The technical field to which the invention relates.

Variants of the present invention relate to the detection of leaks through a wired circuit using a network-connected detection module leaks. More specifically, the present invention relates to data collection detection of leaks through module leak is detected during the execution of a sequence of switches in the period when the module power supply is disconnected. Information about the detection of leaks can be passed from module to detect leaks in a period when the power is turned on.

The level of technology

Detection system leakage can be used to detect leaks of liquids, such as water, fuel or hydrocarbons. Such systems for detecting leaks are usually used in buildings or infrastructure, where the potential risk of catastrophic loss in the event of leakage of fluid, such as museums, centres of collection and processing of data or fuel. System leak is detected, usually use the cable to detect leaks that contains one or more conductive circuits and multiple modules to detect leaks. Usually this cable to detect leaks put in place potential leaks or near such a place, and the system is configured to transfer the of igala leak is detected in the alarm system in case of leaks. System for detecting leaks may have information about the location of the leak and the time when this leakage has been detected. System for detecting leaks should probably have a cable for detecting leaks, power supply and telemetry unit to transmit a signal indication about detecting leaks in an alarm system.

Systems for detecting leaks often use small network tools, such as modules, interfaces, sensors (SIM) used to measure the main parameters in the four-wire circuit to detect leaks. Such modules SIM convert the measured analog quantities into digital data that can be transmitted to an alarm system, containing the alarm panel can show the user the presence and location of leaks. In the system for detecting leaks can be used with even smaller dimensions "intelligent connectors" for implementing detection of leaks through the segmented intervals of the cable to detect leaks, for example every 15 m in This way can be independently and simultaneously monitor a large number of segments of the system to detect leaks and to report the results of such control.

Known to many ways to identify leaks with use the of cables to detect leaks, having a four-wire circuit, built in the form of two loops with the measuring system of control lines connected to the ends of the loops. However, this system requires additional separate cables for power supply and for telemetry. Other ways of detecting leaks using more complex eight-wire system, in which there are special wires for power supply, digital telemetry and detection of leaks in the same cable. For example, two wires can be used for power supply, two wires for digital telemetry and the other four wires can be used to detect leaks. However, such a complex system requires more expensive eight-wire cables. Moreover, these eight systems may be incompatible with many of the previously installed systems to detect leaks. Therefore, there is a need to create a four-wire systems that allow for power, telemetry and detection of leaks using a four-wire cables. For these reasons, and in accordance with other considerations arose the need for the proposed improvements here.

Its sole purpose is to outline some principles in a simplified form as a Preface to the more detailed description that is presented later.

Different ways, in General, focused on ways to ensure leak is detected using the measuring cable receiving power and transmitting data by radio. Some options are aimed, in particular, to methods of detecting leaks using the measuring cable receiving power and transmitting data by radio, for use in four-wire systems to detect leaks. In one embodiment, for example, a system for detecting leaks may contain a module for the detection of leaks that have multiple wires containing one or more collecting points. Such a module for detecting leaks may further comprise a capacitor configured to maintain an electrical charge to ensure module energy when the power is turned off, and a few keys that are managed by the processor. The processor may initiate a predetermined sequence of switching, when it is discovered the fact of the transition condition is with power-off. During the execution of this sequence switching can occur in data collection detection of leaks in one or more collector points. The collected data about the detection of leaks can be recorded in the Ledger group. A module for detecting leaks can transmit the recorded data about the detected error condition when the power is turned on. Other options are also described and claimed.

Some of the options, in particular, is aimed at creating ways of implementing detection of leaks using the measuring cable receiving power from the measuring device and transmitting the data by radio, using modules to detect leaks, which can realize the detection of leaks, power and telemetry features using a four-wire cable. Further, some options are aimed at creating systems to detect leaks using multiple modules to detect leaks that are located at certain intervals along the four-wire cable to detect leaks. As a result, these options can improve the feasibility, scalability, modularity, R is scheremet or operational compatibility for the operator, device or network.

In one embodiment uses a method of time sharing for two of the standard four wire sensor schematic. These two wires are the power bus, working only part time. In the state when the power is turned on, two insulated wires in the standard four-wire measuring cable used to supply power to several independent modules, located in the user-selectable points along the measurement system cable. After a sufficient period of time so that each module could charge your own storage capacitor, the power in the tire off. This event off triggers in each module execution cycle of the switching and measurement. At this time the microprocessor, switches, and analog-to-digital Converter operate using the energy stored in the specified native storage capacitor.

Installed on-Board microprocessor planning the transfer of data packets during periods when the power is turned on, if conditions so require. The microprocessor may also from time to time to transmit control packets, the button to confirm all modules and alarm system stay connected.

There is also described and claimed other options. Various options can contain one or more elements. The element may contain any structure, organized to perform certain operations. Each element may be implemented in hardware, software or any combination of software and hardware, required to obtain a given set of design parameters or limitations of characteristics. Although the option can be described using an example from a limited number of elements in a certain topology, this may include more or less elements in alternate topologies, we need to implement a given implementation. It should be noted that any reference to "one" or "some option" means that a particular feature, structure or characteristic described in connection with this option enabled at least one option. When in various places of this description appears in the phrase "in one embodiment", these phrases do not necessarily all refer to the same option.

In the drawings, the same numerical reference designators used to refer to similar elements. In the following description numerous specific p is fractional for a better understanding of the invention. It is obvious, however, that can be offered to new versions without these specific examples. In other instances, well known structures and devices are presented in the form of block diagrams for ease of description. The aim is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the claims.

Fig.1 illustrates a module 100 to detect leaks in accordance with one of the options. Although shown in Fig.1 module to detect leaks has a limited number of elements connected in accordance with a certain topology, it is clear that such a module 100 to detect leaks may have more or fewer elements connected in accordance with any alternative topologies, if required for specific implementations. In one embodiment, the module 100 to detect leaks includes a controller 110, which may be a microprocessor that is responsible for managing the various components of the module 100 to detect leaks. This controller may include various hardware elements, software elements, or various combinations of hardware and software elements. As examples of hardware elements that may be included in the controller, you can specify the devices, processors, microprocessor is s, circuits, circuit components (e.g., transistors, resistors, capacitors, inductors, and so forth), integrated circuits, application-specific integrated circuits (ASIC), programmable logic devices (PLD), digital signal processors (DSP), user-programmable gate arrays (FPGA), memory units, logic gates, registers, semiconductor devices, crystals (chips, microchips, chip sets, etc., as examples of program elements that may be included in the controller, you can specify the software components, programs, applications, computer programs, engine programs, software, operating systems, firmware, firmware, software modules, application programming interfaces (API), instruction sets, or any combination of these components. The decision whether to implement the option of using hardware and/or software elements may depend on a number of factors, such as desired computational speed, power levels, acceptable thermal conditions, the budget cycles of the data transfer rate of the input data transmission rate output, memory resources, the transmission speed of the data bus and other design or functional limitations in accordance with the requirements is of particular implementation.

The controller is connected to the group of registers 120, which may represent one or more positions of the memory used to write data to detect leaks, collected by the controller. These registers 120 may include, for example, a position memory for storing current data set to detect leaks and previous dataset detection of leaks. Discovery data leakage can include information about the location of the leak, the severity of the leak, the time when the detected leakage, or the distance of the leak from a specific module to detect leaks or alarm system. In one embodiment, the data detecting leaks can be a control data transmission module 100 to detect leaks controller AT intervals of time using a timer. The control data may consist of data entered into the system to detect leaks, and can be used to indicate that each module in the system to detect leaks is working correctly. The control data may specify the alarm system, the alarm panel or computer that specific module for detecting leaks correctly reads and transfers the data to detect leaks. If the alarm system, the signal p is Nelson or the computer does not receive the control data from each module to detect leaks at given points in time, can be enabled indication that the system for detecting leaks has one or more defective modules. Possible options in this example are not limited to.

Registers 120 may include computer storage media of different types in the form of one or more memory modules with high performance, such as permanent memory (ROM)), mass storage device, random access (NVR (RAM), dynamic NVR (DRAM), dynamic NVR double data rate (DDRAM), synchronous dynamic NVR (SDRAM), static NVR (SRAM), programmable ROM (PROM (PROM)), erasable programmable ROM (EPROM (EPROM)), electrically erasable programmable ROM (EEPROM (EEPROM)), flash memory, polymer memory such as ferroelectric polymer memory, the memory elements Ushinskogo, memory using phase transitions or ferroelectric memory, the memory structure of the silicon-oxide-nitride-oxide-silicon (SONOS), magnetic or optical memory cards, or media of any other type suitable for recording information.

In one embodiment, the controller 110 may be connected to the transmitter 130, which can be used for data detection of leaks, recorded in the registers 120. The transmitter 130 may be a low-peredach is to, working in the frequency range 900 MHz, for example. The transmitter 130 may use any well-known communication methods and protocols, such as the methods of communication used in packet networks (e.g., public network such as the Internet, private networks, such as the internal network of the enterprise, and so on), the circuit-switched channels (for example, the public switched telephone network (PSTN) or in networks representing a combination of networks with packet-switched and circuit-switched channels (with appropriate gateways and converters). The specified transmitter 130 may include standard controls communication of various types, such as one or more communication interfaces, network interfaces, network interface cards (NIC), radios, wireless transmitters/receivers (transceivers), wired and/or wireless communication lines, physical connectors, and so on, Such a transmitter 130 may communicate with one or more interconnected network devices that are used to collect data for the detection of leaks and/or for communication of these data, such as alarm systems, alarm panels, or computers, for example.

In one embodiment, the discovery data leaks, recorded in the registers 120 may be transmitted to the alarm panel by one or more wires using the-W method, referred to as the telemetry on the wire supply. This method can be applied in addition or alternatively, the data transmission using the transmitter 130. In this way, the system to detect leaks, installed in areas sensitive to noise, and can avoid the use of radio communications. In one embodiment, the data error detection can be transmitted over the same wires that are used as a power rail in the phase power supply, each work cycle.

In one embodiment, the controller is used to manage multiple keys, such as keys 151, 152, 153, 154, 155 and 156, which may represent, for example, low-power MOSFETs with low on-state resistance. This controller can initiate a predetermined sequence of switching these keys 151, 152, 153, 154, 155 and 156. This escape sequence can be initiated when the controller detects a particular state of the module 100 to detect leaks, such as state off power. An example of such a given sequence shown in the timing chart shown in Fig.3 that will be described in more detail below.

In one embodiment, the module 100 to detect leaks is connected to the power supply, and other modules for which the detection of leaks using multiple wires, such as wire 181, 182, 183 and 184. These multiple wires can be, for example, one four-wire cable to detect leaks. It may be the cable for detecting leaks, widely used in the industry. This cable is for detecting leaks usually contains first and second conductors are located at some distance from one another. If there is liquid between the two measurement wires of an electric circuit. If present fluid enough to create a contact between the first and second conductors, the circuit will not occur. Such a cable for detecting leaks can be, for example, measuring cable TRACETEK®, manufactured by TYCO THERMAL CONTROLS®. In one embodiment, wire 181 and 184 can be a copper wire section 28 AWG. These wires 181 and 184 can be used as a power rail, is responsible for transferring the supply voltage to the module 100 to detect leakage from the power source. Power bus formed wires 181 and 184 may have a maximum length, for example, 1000 m in Addition, wire 181 and 184 can be used for telemetry transmission by wire of the power supply, the detection of leaks can be passed to the alarm panel through wires 181 and 184 when the power is turned on. In one embodiment, the wires 182 and 183 can before the presentation of a copper electrode wire 30 AWG. Variants of the invention in this example is not limited.

In one embodiment, the module for detecting leaks can be a component in the system is larger for the detection of leaks, receiving power from a single power supply located at the beginning of the line, such as a source of 190 nutrition. This source 190 power can be used to power up to 50 modules for the detection of leaks, for example. Source 190, the power may be passed to the bus voltage, e.g., 48 VDC and have a part timer. The timer in the source 190 power can be used to toggle the enabled status power off power over specified time periods. For example, in power-on state, the system can be in seconds, and the duration of the off state of the power may be less than, for example, 0.5 C. Variants of the invention in this example is not limited.

In one embodiment, wire 181 and 184 can serve as a power bus module 100 to detect leaks. Source 190, the power may also be composed of a current source for use as a current regulator. This allows you to avoid a large voltage drop in the cable of the power bus. In the on state of the power source 190 power supply can supply power for charging is condensator 140 and transmit data using the transmitter 130. The capacitor 140 may be configured to accumulate sufficient energy to power the components of the module 100 to detect leaks while the module is in the off state power. Off power such module 100 to detect leaks can perform a predetermined sequence of switching and collect discovery data leaks.

In one embodiment, the module 100 to detect leaks may have one or more collection points, such as collector points 171, 172 and 173. In this embodiment, the collector point 171 can continuously monitor the state of the current through the module 100 to detect leaks. Collector points 172 and 173 can be used to collect data for the detection of leaks in specific points in time during the execution of a given sequence that takes place off the power. These data detection of leaks can include information about the location of the leak, the severity of the leak, the time when the detected leakage, or the distance from the spill area to a specific module for detecting leaks or alarm system. Variants of the invention in this example is not limited.

Fig.2 illustrates a variation of a system 200 for detecting leaks. This system 200 to detect the Oia leaks may include one or more modules to detect leaks, such as the module 100 to detect leaks, shown in Fig.1. As shown in the drawing, the system 200 for detecting leaks includes modules for detecting leaks with numbers 210, 220...n, where n is a positive integer modules to detect leaks. These modules to detect leaks in the system 200 for detecting leaks can be located along a four-wire cable to detect leaks at regular intervals to create segments that can be controlled simultaneously. Thus, each module for detecting leaks can be a specified segment of the cable to detect leaks, such as 5 or 100 meters In one embodiment can be used in four-wire cable for the detection of leaks, such as described above for Fig.1. Two-wire power bus can be built using two of these wires, such as wire 181 and wire 184, shown in Fig.1. The negative wire can be continuously located at the end of the line power source to farthest module. Positive wire can be terminated in each of the modules by means of a key in the form of, for example, field-effect transistor with low on-state resistance.

In one embodiment, a system for detecting leaks uses the principle of Dover who I trust approach. In this approach, each module for detecting leaks "believes" that the modules to detect leaks along the cable before and after this module, perform the same functions data collection detection of leaks in process sequences of simultaneous switching. In this way, each module can perform a full set of measurements for accurate detection of the leak and determine its location only when similar modules before and after this module, perform the same sequence of closures of keys and measurements in advance mutually fixed schedule, which runs for these modules at the same time on the fact of recognition by all modules of the voltage drop when the power is turned off. Similarly, each module for detecting leaks will send data to detect leaks and to charge its capacitor being in power-on state.

Fig.3 illustrates a timing diagram of operation of one embodiment of the module for detecting leaks. In this embodiment, since the time t0each module to detect leaks in the system to detect leaks can perform the same procedure or sequence switch within a predetermined period of time, such as 200 MS or 500 MS. In % the CE perform this sequence each switch module for detecting leaks can produce only four voltage measurements. This is the number of voltage measurements may be more or less depending on the specific design decisions.

As shown in Fig.3, the keys are set in accordance with a given configuration in the initial period of time, to smooth capacitive effects. In one embodiment, at time 40 collector point (this may be a collector point 172, shown in Fig.1) performs the first measurement to collect discovery data leakage or data capture). Another dimension for data collection detection of leaks in the collector point In can be performed at time 70. The third and fourth dimension for data collection detection of leaks can be made at time 130, one in each of the manifold of points b and C. the collector point may correspond to a collector point 173, shown in Fig.1.

Data collected during execution of the sequence switch, may be recorded in the Ledger group "current values". The content of registers current values can be compared with the contents of register "previous value", where the recorded data collected during the previous state off power. The comparison can be applied to a number of threshold rules to determine, in sufficient data in the registers of the current values of ex is evidence from the data in the registers previous values to request data that indicates a leak. If you want to send the data, may be prepared packet of data for transmission, which is then passed to an alarm system or alarm panel. Similarly, when detecting the control data to the transmission can be prepared a package containing these control data, and then transmitted to the alarm system or alarm panel. Discovery data leakage or control data can be transmitted to the alarm panel in the power-on state using the transmitter or using the power bus module to detect leaks.

In the present application includes several schemes of logical processes, representing examples of how the implementation of new aspects of the proposed architecture. Although for ease of explanation, one or more of the methodologies presented here, for example, in the form of schemes of logical processes, depicted and described as a sequence of steps, you should understand and recognize that these techniques are not limited to the order of execution of actions, and some of these actions can according to the present invention is made in another non-illustrated order and/or concurrently with other actions, different from what is shown and described here. For example, experts in rassmatrivaemoi region must understand and recognize, in an alternative embodiment, the method can be represented as a series of unrelated one to another of States and events, for example in the form of diagrams of States. Moreover, not all the steps in the method may be required for a new implementation.

Fig.4 illustrates a variation of the scheme logic of process 400. This logical process 400 may represent some or all of the operations performed by one or more of the options described here. In the variant shown in Fig.4, the logical process 400 begins with the enabled status of the power supply unit 405. For example, one or more of the wires constituting the cable to detect leaks, can begin to transfer the power to the module for detection of leaks, such as the module 100 to detect leaks, described above with reference to Fig.1. This transition is enabled supply can occur at set intervals and can be initiated by a timer included in the power source.

The logical process 400 may charge the capacitor in the module for detection of leaks while in the power-on state in block 204. For example, a capacitor capable of providing power to the module for detection of leakage in the off state of the power supply can be charged in the power-on state. This state included the power supply can be configured in the form of a predetermined period of time in accordance with the design of a particular system to detect leaks or module to detect leaks. For example, the state of the included power supply can be configured in the form of a specified amount of time, the duration of which depends on the used capacitors or power requirements imposed on a particular system to detect leaks or module to detect leaks. Variants of the invention in this example is not limited.

The logical process 400 can determine, is over whether a given period of time for an enabled state, in block 415. In an alternative embodiment, block 415 may determine whether fully charged capacitor in a module to detect leaks. When you expire a given period of time for the enabled status of the power supply and/or when the capacitor module to detect leaks is fully charged, the system can switch to the off state power. Thus, one or more wires in the cable for detecting leaks can be temporarily used to detect leaks instead serve to transfer the supply voltage. Off the power, because one or more power wires are used to detect leaks, the module for detecting leaks can get energy by using a capacitor, charged while in the previous power-on state. Options image is etenia this example is not limited.

In one embodiment, one or more collecting points in the module for detection of leaks can be used for continuous monitoring module to detect leaks. For example, these one or more collecting points can be used to determine when the module is in the off state power or in power-on state. In block 420, the controller module to detect leaks can trigger a sequence of switching, when said one or more collecting points found off the power. This sequence of switching can be performed using multiple keys in the module to detect leaks. These multiple keys can be constructed, for example, on the basis of field-effect transistors with low on-state resistance. Variants of the invention in this example is not limited.

The logical process 400 may collect data detection of leaks in block 425. These data detection of leaks can include data representing the location of the leak, the distance from the spill area to a specific alarm, the severity of the leak, the time when the detected leakage, or was there a leak is detected earlier. Data discovery will crack the EC can be collected in one or more specified points in time during the execution of the sequence. At each given point in time one or more collecting points in the module to detect leaks can collect discovery data leakage. The collected discovery data leakage can be transferred to the controller and recorded in the memory, such as a group of registers in the module to detect leaks. Variants of the invention in this example is not limited.

The logical process 400 may compare the collected data to detect leaks with previously collected data detection of leaks in block 430. For example, the module for detecting leaks may include a set of threshold rules, the requirements which must be met before you will recognize that the detection of leaks indicate leakage. For example, you may want to current the collected discovery data leakage differed greatly from previous data collected for the detection of leaks to generate a command to transmit data to detect leaks. Variants of the invention in this example is not limited.

The logical process 400 may, at block 435 to determine whether the current data collected for the detection of leaks to one or more threshold rules for the detection of leaks, for example, sufficiently whether the current data collected detect leaks differ from previous FDS is data discovery data leakage. If Yes, the current collected discovery data leakage can be transmitted using the transmitter module to detect leaks. In one embodiment, the collected discovery data leakage can be passed with the method of the telemetry transmission by wire of power, according to which the data are transmitted by one or more wires of the power supply module to detect leaks. These are the data to be transmitted detection of leaks can be transferred during the next state included power supply to the alarm system to the alarm panel or PC used to monitor the status of the system to detect leaks. Variants of the invention in this example is not limited.

The logical process 400 may, at block 445 to determine whether the control data in the current data collected for the detection of leaks. The control data may consist of data transmitted at set intervals by the controller in the system to detect leaks. The control data may be used to indicate that each module in the system to detect leaks is working correctly. The control data may serve as an indication for the alarm system, alarm panel or computer that specific module for the detection is of leaks reads and transfers the data to detect leaks properly. If the alarm system, the alarm panel or the computer does not receive the control data from each module to detect leaks at given points in time, can be signaled that the system for detecting leaks has one or more defective modules. Variants of the invention in this example is not limited.

The logical process 400 can transfer data detection of leaks, containing new information about the leaks or the control information in block 440. Data transfer must occur in power-on state. These transmissions can be performed by a transmitter in the module for detection of leaks, such as low-power transmitter 900 MHz range. In an alternative embodiment, for transmission can be applied the way telemetry through the wires of the power supply, when the data are transmitted by one or more wires of the power supply module to detect leaks. The receiver system, such as alarm system or alarm panel, you may receive the transferred data detect leaks and to evaluate these data with the goal of highlighting information about new leaks or about the functioning of the system. Information about all detected leaks can be presented to the user on the display embedded in the signal panel. Variants of the invention in this example is not limited.

Logs the definition process 400 can be completed in block 450 or data transmission detection of leaks, or without the transfer of these data. Some options can be described using the expression "connected" ("coupled" and "connected" ("connected") together with their derivatives. These terms do not have to be synonymous with one another. For example, some options can be described using the terms "connected" and/or "connected" to indicate that two or more elements are in direct physical or electrical contact with one another. The term "connected", however, may also mean that two or more elements are not in direct contact with one another, but still cooperate or interact with one another.

It should be emphasized that the invention is given here so that the reader can quickly "get" the essence of the technical description. The abstract provided with the understanding that it should not be used to interpret or limit the scope or meaning of the claims. In addition, in the above detailed description, you can see that various characteristics are grouped together in a single embodiment for purposes of clarity of description. The method described in the description should not be interpreted as a reflection of intention to declare options demanded more signs than is explicitly stated in each item of the claim. On the contrary, as shown by the subsequent clauses of the formula, p is admit invention does not contain all the features of one of the considered options. Thus, the following paragraphs are included in this detailed description, with each item by itself describes a single option. In the accompanying claims, the terms "including" ("including") and "where" ("in which" are used as the plain-English equivalents of the respective terms "comprising" ("comprising") and "where" ("wherein"), respectively. Moreover, the terms "first", "second", "third", etc. are used merely as labels, and are not intended for presentation of any numeric requirements indicated in these terms of objects.

SUBSTANCE: fuzzy adaptive position method of automatic control of objects with discrete executive devices is proposed, which is realised by means of a logic controller and consists in generation of control parameters according to fuzzy rules and feeding these control parameters to an object. Control parameters generation is divided into two levels, at the first of which with the help of fuzzy logic they localise (identify) the control range, where further adaptation will be carried out. Localisation of the control range is carried out by definition of the main (base) value of the control parameter of this range according to the formula: Uad1=Uo(1-β)+Ukβ, where Uad1 - adaptable control parameter, Uo and Uk - control parameters in two extreme (opposite) conditions B of the object, β - normalised equivalent of object condition (β=0 at Bo, β=1 at Bk, where Bo - initial condition of the object, Bk - final condition of the object), taken as the value of the parameter of the adaptive middle position at this range, and at the second level the value of the control parameter is defined with the help of the adaptive three-position control method.
