The scope of the invention

The present invention generally relates to a flow regulator and, in particular, to a system and method of operation of the regulator with low power consumption, providing selective enabling and disabling of individual components of the controller to reduce energy consumption.

Background of the invention

When the control fluid medium in industrial processes, for example in the oil and gas pipelines, chemical processes and so on, is often required to ensure the reduction and regulation of pressure fluid. To do this usually use regulators, providing an adjustable restriction of flow through the regulator. The task of the regulator in this application may comprise flow control or other parameters of the process, but the restriction is, by its nature, involves the reduction of pressure as a by-product of its function of flow control. As a concrete example of the application of the regulator, you can specify the distribution and transportation of natural gas. The distribution system for natural gas typically includes a network of pipelines laid from natural gas fields to one or more consumers. For transporting large volumes of gas to carry out the compression of gas by increasing the pressure. When Postup the attachment of the gas in the distribution system and, in the end, consumers gas pressure reduced by the pressure reducing stations. For reducing the pressure of the gas at pressure reducing stations typically use regulators. An important requirement to the distribution systems for natural gas is their ability to provide consumers with sufficient volumes of gas. The throughput of this system is usually determined by the pressure in the system, the size of the pipeline and controls, and to assess the system capacity is often used simulation model. To determine the accuracy of the model system using data flow in the various input points, the points of pressure reduction and output points. The point of pressure reduction have a significant impact on the throughput of the gas distribution system and therefore it is important that the system model accurately simulated the point of pressure reduction. However, the point of reducing the pressure inside the distribution system and therefore are not considered to be points of transition (i.e. the points at which control the gas flow passes from the distribution system to the consumer). As a result, at the point of pressure reduction flow is usually not measured. In addition, since the point of pressure reduction are not points of transition, they do not make high demands on precision. the such problems, associated with flow measurement described above with respect to the distribution of natural gas occur in other areas of application of the regulators (i.e. in industrial processes, chemical processes, and so on).

In addition, the wear of knobs during operation leads to their failure, which reduces the ability to control pressure in the pipeline. As a result of damage to the regulator may leak fluid that, in turn, leads to increased losses of fluid and possibly to a dangerous situation. Although damaged regulators can be repaired or replaced, it is not always possible to detect damage to the regulator and to determine whether the regulator has failed. In the conventional distribution system for natural gas, where piping can be run for several miles, the failure is detected and determining whether the regulator has failed, is in big trouble. For regulators, known from the prior art, a typical mode of operation in which all or most of the components of the regulator is always enabled. In those cases, when the power supply controller according to the prior art, is the battery during the operation of these controllers is often unjustified consumption of energy resources, which reduces the efficiency regulate the and. In addition, by reducing the battery capacity of the regulator due to prolonged use or may result from incorrect operation, continued operation of the regulator according to the prior art, all or most of the components which are permanently enabled, reduces the time of operation of such a regulator according to the prior art.

The invention

The method includes the stages on which the transfer controller in the first mode and provide the first command controller to activate the selected sensor from the set of sensors. The controller is transferred to the second mode for operation within a first predefined period of time, and in the second mode, the controller consumes less power than during operation in the first mode. Upon expiration of the first predefined time interval, the controller is again transferred to the first mode. Provide the second command controller for collecting sensory information from the selected sensor.

Detailed description of preferred embodiments of the invention

Figure 1 shows the preferred implementation of the pressure regulator fluid medium, such as a controller 10 of the gas pressure, in accordance with the invention. Shows the controller 10 pressure gas contains a device for measuring gas consumption, which will be described below, in which the measured values of inlet pressure, outlet pressure and flow rate of the holes are used to calculate the flow rate and other information. The following is the duty to regulate to understand in accordance with the principles of the invention can provide a pressure regulator of the liquid and the gas pressure regulator is just one example of a regulator of pressure of the fluid according to the invention.

The controller, shown in figure 1, includes a housing 12 of the regulator casing 14 of the membrane and the upper casing 16. Inside the housing 12 of the regulator is provided an inlet opening 18 for connection to the inlet pipe and the outlet 20 for connection to the exhaust pipe. Throughput hole 22 within the housing 12 of the controller provides communication between the inlet 18 and outlet 20. Inside the casing 14 of the membrane is installed membrane 26, which divides the casing 14 on the upper and lower sections 14a and 14b. To offset the membrane 26 up in the lower section 14b of the cover membrane is provided by push spring 28, attached to the center of the membrane 26.

The membrane 26 is attached to the rod 30 moving along with it. To the lower end of the rod 30 attached throttling element, such as a plate 32 valve, located under the carrying hole 22. The size of the plates 32 of the valve is chosen so that it can completely block throughput hole 22 and, thus, to isolate the inlet 18 to the outlet 20. Obviously, for closing access openings 22 push the spring 28 when estate plate 32 of the valve up. The plate 32 of the valve is made with a variable cross-section, so when the moving plate 32 valve down the area of the clearance (gap) throughput openings 22 increases gradually. Thus, the area of the lumen of the access hole 22 is directly connected with the position of the plate 32 of the valve.

To move the plate 32 of the valve between the closed and open positions to regulate the gas pressure in the upper diaphragm chamber 14a. The pressure in the upper section 14a of the casing can be ensured in different ways. In this embodiment, the pressure in the upper section 14a adjustable load supporting mechanism (not shown). However, without going beyond the scope of the present invention, it is possible to provide the type of controller 10, which uses a control device of another type, such as disposable auxiliary mechanism, or the regulator 10 may be automatic or loaded by pressure.

An alternative method of controlling the gas pressure in the upper section 14a of the casing of the membrane provides for the use of the first tube connecting the intake manifold with the upper section 14a of the casing of the membrane, provided with a first solenoid valve that regulates the gas flow through it. Also provided is a second pipe connecting the upper portion 14a of the casing of the membrane with the issue the SKN pipeline, which is located inside the second solenoid valve regulating the flow through it. The first and second solenoid valves are running on the connected PC. To increase the pressure in the upper section 14a of the casing membrane open the first solenoid valve to apply pressure at the inlet in the upper portion and, thus, to displace the membrane 26 down to open the access hole 22. The gas can be released through the second solenoid valve to reduce the pressure in the upper section 14a and to carry out the lifting of the membrane 26, thereby closing carrying hole 22. Regardless of how and regulated pressure, it is obvious that when the pressure increases, the membrane 26, together with the attached plate 32 of the valve moves downward, opening the bandwidth for the hole 22, while a decrease in pressure leads to the closure of the crossing of the holes 22. This construction is shown by way of example only and not intended to limit the scope of the present invention, because instead you can use other designs known from the prior art.

According to some aspects of the present invention, for measuring levels of pressure P1and R2at the input and at the output, before and after throttling element is provided by the pressure sensors. According pig, the first and second pressure sensors 34, 35 attached to the upper casing 16. From the first pressure sensor 34 departs tube 36, embedded in the pipe connected to the inlet 18 of the regulator. From the second pressure sensor 35 departs another tube 37, embedded in the pipe connected to the outlet 20 of the regulator. Accordingly, although the first and second pressure sensors 34, 35 10 mounted on the upper casing 16, the tube 36, 37 provide the gas pressure at the inlet and outlet, respectively, the first and second pressure sensors 34, 35. Alternatively, the first and second pressure sensors 34, 35 can be placed directly in the inlet and outlet pipes, and wires from the pressure sensors can go to the upper casing 16. To provide temperature correction, if necessary, in the intake manifold place the sensor 48, the temperature of the working environment, which measures the operating temperature.

In the upper casing 16 is also a sensor for determining the position of the valve. According to the shown variant implementation, the rod 30 is attached to the plate 32 of the valve and connected with the diaphragm 26. The progress indicator 40, which preferably is a continuation of the rod 30 passes from the membrane in the upper casing 16, so the position of the progress indicator 40 corresponds to the position of the plate 32 of the valve. The sensor contains m is the mechanism of perception of movement of the indicator, preferably, the Hall sensor. The Hall sensor includes a magnet Hall 42 attached to the upper end of the indicator 40. Inside the upper casing 16 is a magnetic sensor 44, perceiving the position of the magnet Hall 42. Determining the position of the magnet 42, it is possible to determine the position of the plates 32 of the valve, and therefore, the area of the lumen of the access hole 22. To provide a visual indication of movement of the valve with stroke indicator 40 may be associated with the second indicator (not shown). The second progress bar goes from progress indicator 40 upward through the upper casing 16 and extends above the upper surface of the upper casing 16.

Alternatively, to measure the movement of the plates 32 of the valve can be used radar transceiver (not shown)located above the progress bar 40 in the upper housing 16. The radar transceiver detects the position of the progress indicator 40 and transmits a signal characterizing the position of the progress bar. It is obvious that the position of the plate 32 of the valve can be defined in different ways, besides using the above-described magnet 42 and sensor 44. For example, it is possible to provide the laser sensor or in the top 16 for measuring the position of the progress indicator 40, or in the casing 14 of the membrane for the direct measurement of the position of the membrane 26. In the last version posted is of a laser sensor indicator 40 is not required. In addition, to determine the position of the valve it is possible to use an ultrasonic sensor. Figure 2 presents an alternative implementation, in which to determine the position of the valve measure the loading pressure in the upper section 14a of the casing of the membrane. It is obvious that the position of the plate 32 of the valve varies the pressure in the upper section 14a of the casing valve. In this embodiment, for measuring the pressure in the upper section 14a of the casing of the membrane in the upper casing 16 includes a sensor 46 loading pressure. The measured loading pressure can be used to determine the position of the valve. Going back to the version of the implementation presented in figure 1, note that the output signals of the first and second pressure sensors 34, 35, as well as travel sensor 44 is fed to the electronic control unit 50 meter. The electronic unit 50 meter can be performed as an integral part of the regulator, for example in the upper casing 16, as shown in figure 1, or can be placed separately. The flow through the crossing hole controller 10 determines, based on the inlet pressure, outlet pressure and the position of the valve. In the case of sub-critical gas flow rate, to calculate the flow rate using the following algorithm:

F=SQRT{{K SUB 1}OVER{G*T}}*K

sub 2*Y*P sub 1*sin sub 3

SQRT{{P sub 1 - P sub 2}OVER{P sub2}}, where

F - flow

K1- constant absolute temperature,

G is the specific weight of the fluid,

T is the absolute temperature of the fluid,

To2- permanent position stock,

Y - position stock,

P1- absolute inlet pressure,

To3- permanent shape of the balancer and

P2the absolute pressure at the exit.

Constant of the rod position and shape of the balancer To2and K3are determined by the particular size and type of regulator and mainly depend on the specific shape and size of the balancer. Specialists in this field it is obvious that the product2and Y may be equivalent to the traditional factor aperturevalue flow.

The above algorithm is designed to calculate the subcritical (i.e. under the condition of P1-P2<0,5P1) gas flow through the regulators valve type with linear metal rocker. For critical gas consumption used a modified calculation, in which there is no sine function. For other types of regulators, for example, with non-linear metal rocker and regulators elastomeric type uses a similar algorithm, however, constant K2the position of the rod becomes a function associated with the differential pressure ΔP (i.e. the pressure difference P1P2at the entrance and in the course) and/or the position of the valve stem, what is well known from the prior art. For fluid flow equation takes the form:

F=SQRT{{K SUB 1}OVER{G*T}}*K sub 2*Y*

SQRT{P sub 1 - P sub 2},

where

F - flow

K1- constant absolute temperature,

G is the specific weight of the fluid,

T is the absolute temperature of the fluid,

To2- permanent position stock,

Y - position stock,

P1- absolute inlet pressure,

P2the absolute pressure at the exit.

A similar calculation is used according to a variant implementation, presented in figure 2, which provides the measurement of the loading pressure in the upper section 14a of the casing of the membrane to determine the movement of the valve, except that instead of a constant K2the stem position and Y position of the rod used constant K4the loading pressure loading pressure gauge PL. Constant K4the loading pressure also depends on the specific application and must be determined for each type of controller 10. For nonlinear elastomeric throttling elements constant K4the loading pressure is a function ΔP and PL.

In a preferred embodiment, the inside of the upper housing 16 is also block 52 observations of local consumption. Block 52 monitoring local is ashada contains an electronic meter, outstanding information of the total consumption. Block 52 monitoring local consumption also includes an output port that provides access through a portable communication device to obtain the total flow and the zeroing of the meter for future use. In the preferred in the present embodiment, the block 52 monitoring local consumption contains an LCD display, mounted in the upper casing 16. Cover 17 attached to the upper part of the upper casing 16 has a transparent plastic window that allows you to see the LCD display.

The communication unit 54 transmits the data flow to the auxiliary communication device 55, such as a remote terminal (UT), PC or any other device that is able to poll the management bodies of the regulator. The communication unit 54 may include an antenna 53 to transmit information to the remote reading system measurements (not shown). Includes a power supply 56 for supplying power to flow measuring device. The power supply 56 is made with the ability to provide regulated voltage for all devices and can be powered from the known from the prior art source, such as solar panels, battery and DC power and AC.

Obviously, the electronic unit 50 meter unit 52 of observing the local consumption, the communication unit 54 and the power supply 56 may be provided separately, as shown in figure 1, or may be provided on one main electronic Board located inside the upper housing 16.

The design flow through the regulator 10 can be quickly and easily calibrated using a separate flow meter 58. The flow meter 58, which may be a measuring device of a turbine or other type, temporarily inserted into the exhaust manifold to measure the actual flow rate of the fluid. The flow meter 58 provides feedback with the auxiliary communication device 55 (UT, PC etc) or directly from the main electronic Board. Feedback can be used to generate the error functions based on the observed conditions of flow, which is then used in the calculation of the flow regulator 10, which provides more accurate data flow.

Figure 3 shows the currently favored option exercise flowmeter regulator and diagnostic devices, indicated generally by position 100. According to figure 3, the device 100 comprises a cylindrical housing 101, the first end 102 which is designed to connect to the controller (not shown). As in previous versions of the implementation, the slider is positioned in the flow channel for the fluid, having an input section and you the same section. Within the cylindrical body 101 is a progress indicator 103 (figure 4)which is attached to the membrane (not shown) in the controller. According to the shown variant implementation, to register the position of the progress bar 103 uses the Hall sensor. Section 104 of the progress bar 103 is made of magnetic material having pole pieces. The Hall element 105 (figure 4) is located so as to detect the section 104 of the magnetic material and to generate a position signal corresponding to the position of the progress bar 103.

The cylindrical body 101 is attached to the casing 106 having a first pressure port 107 and the second pressure port 108, an auxiliary pressure port 109 and the auxiliary port 110 (Fig 3). In the first pressure port 107 is inserted tool 111 of the first pressure sensor, which is connected by a tube (not shown) to the input section of the flow channel. The second pressure port 108 is inserted tool 114 of the second pressure sensor, which is connected by a tube (not shown) with the output section of the flow channel. In the auxiliary pressure port 109 can be inserted tool 115 of the third pressure sensor for measuring the third point pressure. The third pressure sensor 115 can be used to measure pressure in different places, including in the flow channel or in the controller for determining the stroke of the plunger, which is more in detail described above in connection with the previous embodiment. In a preferred embodiment, provided by the fourth point pressure 117 for measuring atmospheric pressure. For reception of digital or analog signal coming from another device, such as a temperature sensor 48, shown in figure 1, have an auxiliary port 110. In addition, for connection with the external device has a port I/o 112, which is described in more detail below.

Inside the casing 106 is located a few electronic circuits 120A-e to control various operations of the device 100 (figure 4). In the present embodiment, the first (or main) circuit Board 120A may include an interface for the first, second, and third pressure sensors and gauges atmospheric pressure and a connector for Hall sensor 105. The second electronic Board (or a communication card) 120b includes an interface for communication with external devices. The second electronic Board 120b may include a connector for wired communication, for example for the modem card, driver RS232 communication and CDPD modem. Additionally or alternatively, it is possible to provide a transceiver for wireless communication. The third (or the main electronic Board 120C, preferably contains a processor, a memory unit, a time clock, and communication drivers for the two communication channels. The processor may include, without limitation, one or a few the to the above algorithms, for the calculation of flow, although the memory block can store selected parameters, such as high and low pressure on every day. An optional fourth electronic circuit 120d provides an interface for the auxiliary device I/o 55. As examples of such devices I/o can be mentioned a leak detectors, methane detectors, temperature sensors and level sensors. Also provided is the fifth card e (switching fee)with the controller power supply, workers connectors (to connect to the device I/o), uninterruptible power supply and connectors, into which you can insert other cards 120a-d. Although in the shown embodiment, there are five cards 120A-e, it is obvious that, without departing from the scope of the invention, it is possible to use a single electronic charge, less than five electronic circuit boards five or more electronic circuit boards.

Obviously, the connection between the device 100 and the external device may be accomplished through the RF modem, Ethernet or other known communication systems. The processor allows external devices to enter into the device 100, information such as the desired point of job pressure and conditions alerts and retrieve data stored in memory. The extracted data can include a log of alerts and saved operating parameters. For example, the extracted information m which may include the history of the pressure at the inlet and outlet, periodically stored in the memory unit that allows the device 100 to provide the function of the Registrar pressures. According to certain aspects of the present invention, the processor includes generating alerts. The first part of the procedure involves comparing the measured parameters (i.e., inlet pressure, outlet pressure and stroke) with defined user defined limits, which is schematically illustrated in figure 5. In addition, you can run one or more logical podracer that compare at least two of the measured parameter and generate an alert signal on the basis of specific logical operations, examples of which is shown schematically at 6 and 7A-7D.

Turning first to the alarms about the levels indicate that initiates a check of 150 to determine the presence or absence of restriction level entered by the user. First, pressure, speed, flow rate and parameters of the battery 151 compares with the user-entered limits "high-high". If any of the parameters exceed the limits of "high-high", then read 152 date and time and register 153, a corresponding warning signal is "high high". Then, the measured parameters are compared 154 with the user-entered limits "high". If any p is the parameters exceed the limits of "high", then read 155 date and time and register 156 corresponding warning signal "high". Then the parameters are compared to 157 with the user-entered limits "low". If any of the parameters is less than a user-entered limit "low", then read 158 date and time and register 159 corresponding warning signal "low". Finally, the parameters are compared with 160 entered by the user outside of the "low-low". If any of the parameters is less than the limit of the "low-low", then read 161 date and time and register 162 corresponding warning signal "low-low".

You can set additional alarms based on a design flow of F. for Example, the user can enter the limits for instantaneous or accumulated flow. When the design flow F exceeds any of these limits, runs the alert phase. You can provide another signal on the basis of the stroke of the rod. The user can enter the limit for the accumulated distance of the stroke of the rod and to trigger an alert support, when the accumulated stroke will exceed this limit. After checking the user entered alerts you can run one or more logical podracer to determine the presence or absence of any of the terms of the logical signals. the preferred embodiment, each of the logical sub-procedures are combined into one, combined logical subroutine, illustrated in the General form of figure 6. According to Fig.6, the subroutine begins with step 165 collecting all the data of pressure and stroke, and calculating the flow through the pressure regulator. Then each of the measured parameters as compared with other measured parameters, and any user-defined points of the installation. Control logic signals alerts for pressure at the inlet 166, the pressure at the exit 167, auxiliary pressure 168, stroke rod 169 and flow 170. You can also provide additional logical alerts for feedback from the third pressure sensor and an auxiliary device connected to the connector 112 input/output. After receiving the relative values of each parameter checks the logical signals that are described in more detail below.

On figa schematically shows a preferred sequence of operations to determine the logical signals on the basis of inlet pressure (step 166). First, the subroutine checks at step 172 whether the value entered to the inlet pressure. If the entered value is related to the inlet pressure, the subroutine determines whether the measured inlet pressure to be greater (step 173), less (step 174) widen the th user or equal to the value (step 175). For each comparison (i.e. steps 173, 174 and 175) are a sequence of sub-steps, illustrated in figv-7D.

If the signal requires that the inlet pressure was above a given threshold, the subroutine first checks at step 176 a specific value of pressure at the input entered by the user (pigv). If the user has entered the value of the inlet pressure, the measured value is compared at step 177 with the entered value. If the measured value is greater than the entered value, then set at step 178 the flag inlet pressure is greater than". If no specific user-entered value is not used, then the subroutine checks at step 179, whether it is necessary to compare the pressure at the outlet with the inlet pressure. If Yes, then the subroutine checks at step 180 that the inlet pressure more pressure at the outlet. If Yes, then set at step 181 flag inlet pressure more pressure on the output. If the outlet pressure is not used as a logic signal, then the subroutine checks at step 182, the value of the logical signal on the basis of the auxiliary pressure. If the auxiliary pressure is used as a logic signal, then the subroutine checks at step 183 that the inlet pressure bol is above the auxiliary pressure. If Yes, then set at step 184 the flag inlet pressure more auxiliary pressure".

According pigs and 7D, the subroutine performs a similar process to determine that the inlet pressure is less than the value of the logical signal alerts or equal to (stages 185-202). In addition, the operations shown in FIGU-7D for output and auxiliary pressure to determine that they are greater than, less than or equal to specific values of the signal. Because these operations are identical, the individual logical block diagrams that illustrate these stages are not provided.

On file presents a logical block diagram of the processing logic signal at step 169 on the basis of progress (figa). Accordingly, the subroutine first checks at step 203 that the logical value of the progress has not been entered. If the logical value of the progress has been entered, the subroutine determines at step 204 whether the measured value exceed a Boolean value. If the logical operator is the limit "is greater than", then the subroutine checks at step 205 that the measured move more of the entered value. If Yes, then set at step 206, the flag move more than. If progress is not used limit "greater than", then the subroutine checks at step 207 the limit of "less than" If the limit "less than detected, the subroutine checks at step 208 that the measured speed is less than the entered value. If Yes, then set at step 209 flag "stroke less than". If the value is "less than" is not used, the subroutine checks at step 211 that the measured speed is equal to the value entered. If Yes, then set at step 212 the flag "stroke equal". A similar sequence of operations can be used to determine that the design flow of greater than, less than or equal to the value of the logical signal flow that are invoked at step 170, shown in Fig.6.

On the basis of Boolean flags that can be set may include certain logic signals based on the comparison of the two measured parameters. For example, you can set the starting signal warning about the problem of disconnection, when the piston stroke is equal to zero, and the output pressure increases (the current outlet pressure more than the nearest time previously measured pressure at the outlet). Under appropriate operating conditions for establishing a corresponding logical flags that triggered an alert about the problem of disconnection, which may indicate leakage of fluid through the pressure regulator, possibly due to damage to the throttling element. The other logs the definition of the alert signal can be generated, when the value of turn is greater than zero, and the signal pressure at the output is reduced, which may indicate damage to the rod. Another logical alarm signal can be generated when the value of the stroke is greater than zero, and the signal pressure at the inlet increases, which may indicate damage to the stock or other problem with the regulator. Another logical alarm signal can be triggered when the turn signal is greater than zero, and the signal pressure at the output more user-entered limit the outlet pressure, which may indicate a problem with the auxiliary mechanism, the host controller. You can enter other logical alarms, which take into account the various measured and calculated values, which allows you to immediately indicate other potential problems with the controller.

The block of memory associated with the processor, preferably, contains a file alert, which tracks the date, time and type of alarm. The file access notification can be done with an external communication device that allows you to retrieve a history of alerts. In addition, the processor preferably contains the outline of the report deviations (TNA), which automatically passes any conditions alert to a remote host computer. Accordingly, it is possible to quickly inform you about potential problems in t is webpromote and to identify the specific component or damaged part.

The controller 10 of the gas flow typically has a power source type battery and is specially adapted to minimize power consumption. On Fig shows a diagram 300 with reduced power consumption, designed for minimum energy consumption or by low static power consumption, or through the use of regime switching cycle. The controller 10 of the gas flow contains the schema 300 with reduced power consumption, the individual components which are normally in standby mode and included the need to implement a measurement or diagnosis. Economy circuit with reduced power consumption 300 in the General case contains cost 120 with a processor, connected with the possibility of communication to the Board connection 120b and to the Board 120A input/output sensors.

The CPU 304 operates in three different modes: active mode in which the CPU 304 consumes the power required to support all operations, standby mode in which the CPU 304 consumes reduced power required to support the operations of its internal systems, and in the lock mode in which the CPU 304 practically disabled and operates at minimum power level. When the standby mode operating frequency of the CPU 304 is reduced to save energy. When going into lock mode, the CPU 304, the internal clock generator 318 and the internal RAM 322 are turned off to save more energy.

Block 312 internal I/o also prevents the CPU 304 about the installation of optional communication card, such as card RS232, modem at 2400 baud, interface card cell phone CSC, interface card cell phone cellular communication system with transmission of digital packet data interface card cell phone system multiple access code division (mdcr) or card radio interface Unit EEPROM 316 is used to store settings, calibration and security controller 10 of the gas flow. Block 314 static RAM is a static memory, which is used to store the initialized variables, files, alerts, event files and history files. Plot block 314 static memory is reserved for the download of the firmware, for example, updates to the firmware and functional improvements. This facilitates the implementation of security checks and reliability prior to programming the flash memory 320 updates the firmware. Uninterrupted power supply unit 314 static memory is with the use of replaceable lithium battery.

Communication card 120b provides an interface for external communication with one or more external devices, including the host or master device. The communication unit 120b provides adaptation due to cards of different types, requiring different types of drivers. After you install a specific communication card communication card generates an analog signal, identifying the type of communication card installed, which is supplied to the CPU 304. The CPU 304 uses the data of the analog signal for proper initialization and interfacing with the communication driver Board connection, usually without operator intervention. Communication card comprises a generator signal is La interrupt which throws an INT4 interrupt signal to the CPU 304 on request for communication with the external communication device. In response to the INT4 interrupt signal, the CPU 304 activates the driver on-Board communications, which provides two-way communication between the external communication device and the CPU 304. Communication card 120b may be configured for wired communication, for example via a modem card, driver RS232 communication or wireless communication, for example via modem cellular communication system with transmission of digital packet data (CDPD). Communication card 120b may also be able to pair with other devices, including the modem telephone line, other mobile devices, radio communications device, a satellite interface Fieldbus® or HART interface®.

Board 120A input/output sensors includes one or more analog-to-digital converters (ADC), namely ATP, ATP to facilitate communications between the CPU 304 and various sensors, including the first, second, third and fourth pressure sensors 34, 35, 115 and 117 and the travel sensor 44. The CPU 304 carries out communication with the transducers ACP, ACP by bus serial peripheral interface SPI. Converters ACP, ACP always initiated to maintain the calibration data, but are normally in standby mode to minimize power consumption. The CPU 304 unlocks separate converters ACP, ACP if necessary sprage the Oia with separate sensors 34, 35, 44, 115, 117 for collecting and converting selective readings of the sensors. Board 120A input/output sensors also contains a set of sensor interfaces, including interfaces P1, P2, P3, PBAR first, second, third and fourth pressure sensors and interface TRAVEL travel sensor. The CPU 304 regulates the power supplied to each sensor 34, 35, 44, 115, 117 through the interfaces P1, P2, P3, PBAR and TRAVEL. Communication between the CPU 304 and interfaces P1, P2, P3, PBAR and TRAVEL sensor is provided by the data bus power control SUM. The sensors 34, 35, 44, 115, 117 normally disabled and is enabled only when the need for scanning or sampling. If you want to include a particular sensor 34, 35, 44, 115, 117, the CPU 304 issues a power on command to the appropriate interface pressure. Each sensor interface P1, P2, P3, PBAR, TRAVEL contains a voltage reference, bridgeable power amplifier and power switch. The power switch controls power supplied to the reference voltage, bridgeable power amplifier and sensors 34, 35, 44, 115, 117. Reference voltage source provides power to the sensor, the reference input transducer ACP, ACP and output signal for the bridge amplifier. Using the reference signal at several points makes the circuit 304 with low-power ratio, thereby reducing the effects of drift TNA the signal on the accuracy of analog-to-digital converters.

The sensors 34, 35, 44, 115,117 can work in desktop mode and in standby mode. In standby mode, the sensors 34, 35, 44, 115, 117 consume less power compared to the operating mode. In order to save energy, sensors 34, 35, 44, 115, 117 can be translated into standby mode when they are not in fact used for data collection. For example, the sensors 34, 35, 44, 115, 117 can be translated into standby mode after they have been initialized, and then activated or converted into work mode, when the CPU 304 has requested the data collection. Similarly, analog-to-digital Converter can operate in standby mode and operating mode. According to alternative implementation, the sensors 34, 35, 44, 115, 117 and ADC when not in use, you may not translate into standby mode, just disable. Block 302 I/o expansion is usually placed on a single Board that is interfaced through a single connector expansion bus serial peripheral interface SPI, analog port pins control inputs status. The connector also routes the operation signals from the working connectors on the motherboard 302 I/o expansion. The functions of the Board 302 I/o extensions are usually determined depending on the application.

Figure 9 shows a logical block diagram showing, as a whole works firmware controller 10 is of ashada gas, implemented in the circuit 300 with reduced power consumption. Firmware is stored in flash memory 320. Run the firmware is at the command of the power supply components on the circuit with reduced power consumption, and team power can be generated, the CPU 304 or by the operator at step 402.

At step 404, the CPU 304 starts the initialization process, in accordance with which the initialization circuit 300 with reduced power consumption and sensors 34, 35, 44, 115, 117 according to the setting defined by the operator, for receiving and processing the periodic reads or samples the sensors and settlement expense. In accordance with the setting of the operator knob 10 consumption can access the touch data at different frequencies in different time intervals.

Then, at step 406, the CPU 304 determines, based on the settings specified by the operator whether to initiate a fetch operation. If the setting indicates that the CPU 304 must extract reads sensor, the CPU 304 in step 408 supplies the selected sensors 34, 35, 44, 115, 117 and selected components of the circuit 300 with reduced power consumption, which is necessary for obtaining samples of the readings of the sensors from the converters ACP, ACP. Each of the sensors and the circuit components with low saving is consumption, performing its task in the process of sampling is disabled. The collected data include reading from the sensor 34 to the inlet pressure, the sensor 35 of the outlet pressure, auxiliary pressure sensor 115, the sensor barometric pressure sensor 117 and stroke 44. Other collected parameters include input voltage, the voltage of the battery, the chemical composition of the battery and the ambient temperature of the Board. At step 410, the CPU 304 calculates the flow rate based on the collected sensor information. Then, at step 412, the CPU 304 compares each of the collected readings and estimated flow defined by the operator of the upper and lower limits to determine whether there is any value outside, i.e. corresponds to the condition alerts. The CPU 304 determines any changes to the status of any alarms, such as installation conditions alert to the condition of clearing alerts or conditions of cleaning alert to the condition of installation of alerts and logs its results in the alerts file. After reception of the notification, the CPU 304 is a report deviations (TNA) and automatically transmits the condition alert to a remote host computer through the communication unit 120b. Accordingly, it is possible to quickly inform you about potential problems in the pipeline and to identify the specific component or damaged area.

On the floor is PE 414, the CPU 304 determines whether you want to back up each of the collected readings and estimated flow, based on the tuned frequency of archiving. If the CPU 304 determines that a particular parameter, for example, collected reading or estimated flow, you should back up, then at step 416, the CPU 304 calculates the average value and the accumulated value for this parameter, then registers the values in a history file. The frequency of archiving each of the parameters set by the operator and can range from archiving every minute to archiving every sixty minutes.

If the CPU 304 determines that a particular parameter is not required to back up, the CPU 304 in step 420 adds the value to the current sum of the values of this parameter and tracks the number of parameter values, which were further added, in case the CPU 304 requests to carry out the calculation of the average values of this parameter.

Upon completion of the sampling process, at step 422, the CPU 304 issues a command to perform validation and system diagnostics. The process system diagnostics are performed to verify correct operation of the circuit with reduced power consumption for operation on any waiting requests TNA to ensure that you have applied the latest setup software and hardware for tracking modification software apt the military security to monitor the performance of the battery and to ensure that the regulator 10 gas pressure operates within acceptable limits. In particular, the CPU 304 monitors the power system gas pressure regulator for correct operating ranges in accordance with the limits alert "low"limits alert "low-low"limits alert "high" and limits product alert "high-high". Depending on the voltage levels of the batteries, set the sample rate, the frequency of the internal clock signal, the frequency of the signal pulses of time and levels of communication are setting up appropriate systems of gas pressure regulator to conserve energy and extend battery life. Under conditions of very low power, you can even turn off power to parts of the scheme 300 low power for additional energy savings. Upon completion of tests, the CPU 304 enters standby mode, where it operates at a low operating frequency, which reduces the amount of power consumption. Then, at step 424, the CPU 304 checks various system 35 link in the diagram 300 with reduced power consumption, for example, the communication unit 308, block PLO 310 and a communication card 120b, to determine if any of the communication ports. If the communication port is active, the CPU 304 remains unlocked and returns to e the UPA 406, to determine whether to repeat the process of sampling, and again performs validation systems at stage 422.

If none of the communication ports is not active, the CPU 304 issues a command to give to unlock the CPU 304 via an external interrupt INT1 at the appointed time, then at step 426, the CPU 304 is in the lock mode to save power. When the CPU 304 is in the lock mode, the CPU 304 can be unlocked via an external interrupt INT2, INT3, INT4, issued by, for example, block PLO 310, a communication unit 308 or - connection 120b. Through the assigned period of time at step 428, the give sends to the CPU 304 external interrupt INT1, and the CPU is unlocked again returns to step 404 and again repeats the whole procedure.

Figure 10 are described in more detail, the initialization process performed at step 404. As noted above, at step 402, the initialization process is activated by the command on the exercise of the power supply circuit components with low power consumption. At step 430, the CPU 304 configures various ports I/o to set the correct direction of the signal and the signal levels, the default, to block or disable hardware circuit with reduced power consumption. The CPU 304 also specifies the functions of ports for communication card 120b, the communication unit 308, block PLO 310, converters ACP, ACP and timers, including Gibeah 306.

At step 432, the CPU 304 for implementation through the control of reliability to determine to see whether static RAM suitable software configuration. In particular, three different areas of the SRAM 314 is checked on the basis of known configuration templates. If any of the three different fields does not match the known pattern configuration, static RAM 314 is considered unsuitable. If static RAM 314 is unsuitable, then the CPU 304 at step 434 initializes all memory, including all uninitialized and initialized variables. Then, at step 436 sets the failure flag static RAM. If RAM 314 is suitable, then the CPU 304 initializes only uninitialized variables at step 438 and clears the flag static RAM failure at step 440.

Then, at step 442, the CPU 304 sets the communication unit 306 and give verifies the correct operation of the Gibeah 306. If Gibeah 306 is not working properly or the power Gibeah 306 has been disabled, the CPU 304 reinitializes GIV 306 with the correct functions date and time. At step 444, the CPU 304 checks the modem. If the modem is installed, the CPU 304 initializes the modem, then power off the modem. The modem power is turned off to supply power to other equipment circuit with reduced power consumption, to limit the maximum current draw at startup.

At step 446 is the initialization of the communication ports on the motherboard connection 120b, b is the eye connection 308 and block PLO 310 in accordance with the configured data rate, bits, stop bits and parity. Interrupt INT2, INT3, INT4, designed to initiate communication through the communication ports remain blocked in the initialization process to avoid initiating connections to complete the initialization process. Then, at step 448 to configure all installed modems.

If at step 450 discovered that the static RAM is unusable, then the CPU 304 checks whether stored in EEPROM 316 previously saved configuration memory. Upon detection of a previously saved configuration memory, it is loaded into the SRAM 314 at step 452. If no EEPROM 316 previously saved configuration CPU memory 304 initializes static RAM 314 using the parameters taken by default.

At step 454 initialized parameters of the flash ROM. Update the firmware stored in the flash ROM 320, usually carried out by the operator. Options flash ROM, managed the upgrade process, provide error checking and validation. Then, at step 456 converters ACP, ACP initialized and calibrated to work. Upon completion of the initialization process converters ACP, ACP translate into standby mode to save power. At step 458, the CPU 304 checks the suitability of specified periods of sampling and archiving. The CPU 304 checks the nalitch the E. at least one sample during the active period. Flag is set sampling, and sampling begins immediately upon completion of the initialization process 404.

The sequence of sampling used by the controller 10 of the gas pressure for the selection of different parameters, I/o, for example, reads sensors, various parameters economical schemes and power levels of the batteries, specially designed to minimize power consumption of the battery. Includes only those sensors 34, 35, 44, 115, 117 and schema components with reduced power consumption, which are necessary to implement the fetch operation, after which they are immediately turned off when the sample is collected by the CPU 304. Figure 11 shows an example of a sequence of samples used CPU 304 when reading a selected set of pressure sensors 34, 35, 115 and travel sensor 44, which allows you to minimize the power consumption of the battery and which can be carried out at the step 408.

At step 450, the CPU issues a command to activate the transducers ACP, ACP, sensor 34 of the inlet pressure sensor 35 of the outlet pressure. At step 452, the CPU 304 configures the internal clock generator 318 to issue the enable signal to the CPU 304 after a specified period of time and enters standby mode. The duration of the waiting period depends on the time required for the pressure sensors 34, 35, for sufficient heating to about the ensure accurate reading. The duration of this waiting period may be, for example, fifty milliseconds. At step 454, the CPU 304, unlocked internal clock generator 318, reads the corresponding converters ACP, ACP to obtain sample readings of the pressure sensors 34, 35. Then, at step 456, the CPU 304 issues a command to shut off the pressure sensors 34, 35 and the command to activate the auxiliary pressure sensor 115. At step 458, the CPU 304 converts the filtered reads pressures at the input and output in engineering units. At step 460, the CPU 304 configures the internal clock generator 318 to issue the enable signal to the CPU 304 after a specified period of time and enters standby mode. At step 462 CPU 304, unlocked internal clock generator 318, reads the corresponding Converter ACP, ACP to obtain a reading from the auxiliary pressure sensor 115. Then, at step 464, the CPU 304 issues a command to shut off auxiliary pressure sensor 115 and outputs the command to activate the travel sensor 44. At step 466, the CPU 304 converts a sample derived from an auxiliary pressure sensor 115, in engineering units, and, at step 468 configures the internal clock generator 318 to issue the enable signal at the appropriate time and enters standby mode. At step 470, the CPU 304, unlocked by a signal inside the th clock generator 318, reads the corresponding Converter ACP to obtain a reading from the travel sensor 44. At step 472, the CPU 304 issues a command to shut off sensor turn, then at step 474 converts the read sensor of a course in engineering units. Between sampling periods, the CPU 304 typically goes into lock mode. After completing the survey sensors 34, 35, 44, 115, 117, the CPU 304, before entering lock mode, returns to give 306 command, so that, after a specified period of time issued on the CPU 304 of the interrupt signal INT1 to unlock i.e. translate it into a working mode. A specified period of time corresponds to the time interval between two consecutive sampling periods and depends on the set sampling rate. While in lock mode, the CPU 304 may also be unlocked by the interrupt signal, which demonstrates the request for external communications with the communication device.

Although in the described example was chosen set of sensors within the present invention can be considered a sequence of samples, providing reading fewer sensors or more sensors. For example, the CPU 304 may receive a reading from sensor 117 barometric pressure reading of the battery level and parameters related to performance fees 120C processor. Not going beyond the entity izopet the tion, you can take an alternative sequence selection, the inclusion of selected components necessary for obtaining readings of the sensors, followed by disconnection of the selected components. As noted previously, the controller 10 of the gas flow is supplied from the battery and consumes known power. The power consumed by the regulator of the gas flow, is typically a function of a configurable sample rate. In other words, the higher the sampling rate of the sensors 34, 35, 44, 115, 117, the more power consumption. The CPU 304 monitors the levels of battery capacity and can usually give the estimated date of battery replacement. Perceived the chemical composition of the battery is used to identify the type of battery used as the power source controller 10 of the gas flow. For example, on the basis of perceived chemical composition of the battery, you can determine whether your battery battery lead-acid or lithium battery type. The CPU 304 determines the remaining capacity of the battery based on the received voltage at the battery terminals, perceived the chemical composition of the battery and the known power control gas flow. For a more accurate estimate of the remaining battery capacity of the CPU 304 may also use the data associated with environmental factors, such as perceived is the temperature of the battery.

Returning to Fig, note that the Converter ACP connected with the possibility of communication sensor 502 battery voltage and the sensor 504 of the chemical composition of the battery. The CPU 304 carries out the sampling data read by each of the sensors 502, 504, through the transducer ACP. According pig, the controller 10 of the gas flow can operate in one of four modes battery life: normal mode, the first power saving mode, the second power saving mode and security mode. The CPU 304 translates the controller 10 of the gas flow in the appropriate mode based on the remaining battery capacity. In particular, the sensor 502 battery voltage perceives the voltage at the battery terminals. Converter ATP converts the received voltage at the battery terminals to a digital signal, characterizing the received voltage at the battery terminals. At step 510, the CPU 304 reads the corresponding converters ACP to obtain a read voltage across the battery terminals and the chemical composition of the battery and at step 512 determines the remaining battery capacity. The capacity of the battery and set threshold voltage or threshold containers are stored in memory. The CPU 304 compares the received battery voltage with each of the threshold capacities to identify, operate, if the controller 10 of the gas consumption in the normal operation mode, what erom energy saving mode, the second power saving mode or in protected mode. Logical block, which performs the comparison function, is a component of software and hardware circuits with low power consumption.

At step 514, the CPU 304 determines whether the battery is on the threshold capacity, making up more than 25% full working capacity. If the battery is on the threshold of a capacity exceeding 25%, then at step 516, the CPU 304 issues the appropriate commands to the transfer controller 10 of the gas flow in normal operation. If the battery is at less than or equal to 25%, then the CPU 304 at step 518 determines whether the battery capacity in the range of values less than or equal to a threshold capacity of 25% and greater than or equal to the threshold capacity 15% of full battery capacity. If the battery works in this range, then at step 520, the CPU 304 issues the appropriate commands to the transfer controller 10 of the gas consumption in the first power saving mode.

At step 522, the CPU 304 determines whether the battery capacity in the range of values less than or equal to a threshold capacity of 15% and greater than or equal to the threshold capacity in 5% of full battery capacity. If it is determined that the battery operates in this range, then at step 524, the controller 10 of the gas flow means in the second power saving mode. At step 526, the CPU 304 determines whether the battery is below m is the minimum threshold capacity in 5% of full battery capacity. If the CPU 304 determines that the battery is operating below the minimum threshold capacity, the regulator 10 of the gas flow means in the alarm mode at step 528.

On Fig shows the commands issued by the CPU 304 to transfer controller 10 of the gas consumption in the first power saving mode. At step 530, the frequency with which selected reading sensors, such as read pressure sensor and reading of the sensors is reduced to the first level power saving, and on the stage 532 decreases the clock frequency internal clock generator 318. At step 534 is set alert "low", is a timestamp and the time is logged. In the first power saving mode is still supported the event files, history files, and files warning. However, in the first power saving mode upon the occurrence of certain events may need to increase the clock frequency. Such specific events include, for example, an external interrupt from the communication device, for example, a communication card 120b, the communication unit 308 or block PLO 310. At step 536, the CPU checks whether you want to increase the clock frequency upon the occurrence of certain events. If the CPU 304 determines that the clock frequency must be increased, then at step 538 clock frequency increases for the period necessary to implement functions that require avicennae clock frequency. Then at step 540, the CPU 304 again issue the command to decrease the clock frequency to save battery power.

On Fig shows the commands issued by the CPU 304 to transfer controller 10 of the gas flow in the second power saving mode. At step 542, the frequency with which selected reading sensors, such as read pressure sensor and reading of the sensors, further reduced to a second level of energy efficiency, i.e. the sampling rate is lower sample rate, set at the first level of energy saving. At step 544 all external communications, such as communications via a communication card 120b, stop. At step 546 is set alert "low-low"is the time stamp and the time is logged. The frequency of the internal clock signal generator 318 clock signal remains at a low level. In the second power saving mode event files, history files, and files warning is still supported.

On Fig shows the commands issued by the CPU 304 to transfer controller 10 of the gas flow in the alarm mode, in which the main battery is completely discharged. As noted previously, the event files, history files, and files alerts are stored in a static RAM 314. At step 548 to activate the battery, uninterrupted power supply, for example a replaceable lithium battery, for supplying power to the static ones is some RAM 314, in order, therefore, to support the event files, history files, and files warning. At step 550, all sensors 34, 35, 44, 115, 117, 502, 504, converters ACP, ACP components and circuit Board 120 with a processor, including a CPU 304, off to save energy. Included only static RAM 314. No new data selections are made and not saved before replacing the main battery.

Obviously, though to illustrate a variant embodiment of the invention were used specific thresholds battery capacity, for example 25%, 15% and 5% of full battery capacity, thresholds, battery capacity are the values set by the operator, and, without leaving the scope of the invention, it is possible to install and use alternative thresholds battery capacity. In addition, although the described embodiments of include four modes of operation of the regulator of the gas flow, the use of more or fewer modes is also considered relevant to the scope of invention.
