The invention relates to systems process control or monitoring systems. More specifically, the present invention relates to a system that adds wireless capabilities for field devices of these systems.
Control systems in process plants are used for control and monitoring of production resources used in manufacturing and chemical processes, and for other similar purposes. Usually the management system does this by using the field devices distributed in key points of the process and associated with the control circuit control by means of a closed loop process control. The term "field device" refers to any device operating in a distributed control or monitoring system of the technological process, including all devices used to measure, control and monitoring of technological processes.
Some field devices include the Converter. The Converter should be understood as a device that produces an output signal of the input signal of a physical parameter, or as a device that produces an output signal of a physical parameter based on the input signal. Typically, the Converter converts the input signal to output the Noi signal different species. Types of transformers include various analytical devices pressure sensors, thermistors, thermocouples, strain gages, flow sensors, position sensors, motors, solenoids, indicator lights, and others.
Typically, each field device also includes an electronic communication scheme used for communication with the point process control, or other structure in a closed loop process control. In some installations, closed loop process control is also used to feed in the field device controlled current and/or voltage for the power supply. A closed loop is used to transmit data in analog or digital format.
Analog field devices traditionally connected with the control two-wire current closed loop control process, and each device connects to the control of his two-wire control loop. Typically, the voltage difference between two wires supported within 12-45 In analog mode and 9 of 50 In digital mode. Some analog field devices transmit a signal to the control when the modulation current, the current in the closed circuit, a current proportional registered technological parameter. Others who many analog field device is able to function under the control of the control point change in the value of the current through the circuit. In addition or as an alternative to this closed loop process control can transmit digital signals used to communicate with field devices. Digital communication more efficient for the transmission of information in comparison with analog. The field device can respond and share digital information selectively by the control unit and/or other field devices. In addition, such devices can provide additional signal information, such as diagnostic and/or emergency.
In some installations, wireless technologies are already being used for communication with field devices. Work in wireless version facilitates wired cabling and configuration of field devices. Currently used wireless systems, which made the field device includes an internal battery may charge a solar cell or other way to generate electricity without any wired connection. The problem when using the internal battery occurs when the needs of the energy consumption of wireless devices greatly depend on many factors, such as speed data, items, devices, etc. External to the field device system power supply and the connection for the wireless exchange of information represents a significant improvement in this area.
Wireless power and communications to field devices configured for connection with the field device and for providing a working power supply and wired, preferably digital connection between this unit and the field device. Electronic RF device is configured to provide radio frequency communications. In one implementation, the power source in the above-mentioned block includes one or more solar cells that convert solar energy into electrical energy to power and the said block, and a field device. Wireless power supply and connection provides power to the field device and communicates with the field device according to the standard Protocol industrial relations. The unit communicates wirelessly with an external device, such as a control point on the basis of interaction with the field device.

The present invention includes a wireless power supply and communication that allows field devices developed for wired communication, to work in wireless mode. Although to date there is some development of devices with the addition of wireless connectivity to wired devices, these developments do not function, to release the wired field devices from their control loops, since they are wired, and the power is in their control loops.Fig.1 and 2 depict schematic view and a block diagram of an exemplary field device, which is particularly useful application of wireless power and communications in accordance with the present invention. System process control or monitoring system 10 includes a control or system control 12, which is associated with one or more field devices 14 via a two-wire process loop 16 management. Examples of the process circuit 16 controls include analog 4-20 mA communication, hybrid protocols, which includes analog and digital communication, for example, standard Highway Addressable Remote Transducer (HART®), as well as all other digital protocols, such as standard FOUNDATIONTMFieldbus. Typically, the protocols of process control loops can provide power to a field device, and transfer data between the field device and other devices.
In this example, the field device 14 includes a circuit 18 associated with the actuator/transducer 20 and processing circuit 16 control via the terminal block 21 in the housing 23. The field device 14 is shown as a generator of technological parameter (TP), whereby it is connected with the technology and responds to the indication, for example, temperature, pressure, pH, flow, and other technologies the parameters, and provides the indication. Other examples of field devices include valves, actuators, controllers and display unit.
Typically, field devices are evaluated for their suitability to work in a field where they may be exposed to the environment, such as temperature, humidity and pressure. In addition to the environmental field devices often must withstand corrosive, hazardous and/or even explosive atmosphere. In addition, such devices must operate in the presence of vibrations and/or in terms of electromagnetic interference. Field devices of this type, as shown in Fig.1 represents a broad class of traditional devices, designed to work exclusively in a wired version.
Fig.3 depicts a block diagram of a wireless field device in accordance with the prior art. The field device 34 includes internal module 38 of the power source, the controller 35, a wireless communication module 32, and the actuator/transducer 20. Module 38 of the power supply typically includes a battery powering the field device 34 as long as the battery will require replacement. Some field devices include built-in solar cell. The power source 38 feeds the controller 35 for mutual the action actuator/transducer 20 and the wireless communication module 32. The wireless communication module 32, in turn, communicates with other devices via the antenna 26, as indicated by the number 24. The disadvantage in obtaining wireless capabilities within the device 34 is that if a battery, solar cell, or the wireless communication module is damaged, then the field the entire device must be repaired or replaced. Another disadvantage of using the internal battery is that some users of wireless devices require much more energy than others. For example, if the field device is activated once per minute instead of once per hour, the energy consumption increases. Energy use also varies greatly depending on, whether the device is configured with a minimum number of system elements, or it is filled with all the elements. Thus, the internal power source is not promising in the sense that the different energy demands of different users are poorly linked to each other.
Fig.4. depicts a front view of the wireless unit 100 power and communications, fixed on a field device 14, shown here in probation. Block 100 is preferably attached to the device 14 through the standard pipeline 102 for field devices. When the career of suitable pipe connections include Seba/2-14 NPT, M20 x 1.5, G1/2, and 3/8-18 NPT. The unit 100 may include a joint that allows rotation 104 around the axis 106 and the rotation 108 about the axis 110. In addition, the region 112 of the attachment unit 100 is preferably hollow for insertion of wires connecting block 100 with the device 14. In those implementations that do not require adjustment of the position of the body, the area 112 attachment may simply be a conductive part.
The unit 100 includes a housing 114, mounted on a region 112 of the attachment. The housing 114 contains the schema (discussed in connection with Fig.8) in order to provide the power supply unit 100 and to allow him to communicate with the device 14 in accordance with the standardised production Protocol, such as 4-20 mA HART®, FOUNDATIONTMFieldbus, Profibus PA, Modbus, CAN, or. Preferably the Protocol organizes digital communication to increase the level of interaction between the block 100 and the device 14.
In Fig.4 shows one or more photovoltaic cells 116, mounted directly on the upper surface 118 of the housing 114. In one embodiment, the implementation of the photovoltaic cell(s) 116 form part of the sealed cover to the housing 114. In these embodiments of the cell(s) 116 is preferably covered with a transparent protective shell for protection from external influences. Cell 116 preferably have the t slope of 30 degrees and are used for converting incident light into an electrical voltage for power supply unit 100 and the device 14. Because the block 100 is located outside of the device 14, it can be many variants of block 100 with the photovoltaic cells of different configurations and/or sizes, depending on the specific power requirements of the field device, is attached to the block. It is preferable that the block 100 includes a wireless communication scheme (not shown in Fig.4)associated with the antenna 120. The presence of the external antenna 120 facilitates wireless communication compared with internal antennas, since many coating field devices made of metal and absorb the wireless signal. However, there may be options for implementation with an internal antenna located near radiotransparent section of the housing 114 or cell(-EC) 116. Options for implementation with external antenna yet more practical, because in this case, the block 100 is externally insulated from the environment, which actually developed the field device.
In accordance with one feature of the invention, the unit 100 includes a local user interface. Accordingly, the block 100 may include a display device, such as LCD display 122, which can be mounted directly near one of the cells 116. To receive local user information unit 100 may include one or n is how many local inputs, such as a command button 124. The local user interface is important, because if the joint system block/field device works completely wirelessly, for experts it is more convenient to have a local user interface, instead of challenging the wireless access device via a portable computer device or something like that. The local interface can be used to access the unit, and to access a field device or to both together. In this case, the term "local user interface" means the presence or the local custom entry tool(s) (e.g., command button), the local user output(s) (e.g., LCD), or combining both. In Fig.4 shows that the LCD can be combined with the cell(s) 116.
Fig.5 depicts a front view of the wireless power and communications in accordance with another variant of realization of the present invention. Wireless unit 200 power and communication has a lot to do with the wireless unit 100 power and communications, and similar components are labeled similarly. The main difference between the wireless unit 200 power and communications and wireless unit 100 power and communication is the location of the device display the local users who ski interface. Namely, the unit 200 includes a display located in close proximity to the photovoltaic cell(-EC) 116 or combined with it(mi). Instead, the display 202 is combined with region 112 of the attachment. Preferably, the display 202 is executed independently rotating around the axis 106 of approximately 270°.
The placement of the display of the user interface directly near the region of 112 attachment increases the ability of the modular block 200. Namely, the housing 114 and all of the components can be made similar, thus achieving space saving. In those installations in which the desired user's local display, it can simply be added in the form of a module between the housing 114 and the junction region 204 112 attachment. This modular design is also useful in those implementations in which a single block 200 is used for work and communicate with many field devices, as will be described in more detail in connection with Fig.6 and 7. Thus, if the installation location is hard-coded, then the power supply system, comprising a solar cell and antenna can be mounted remotely using the adapter with cable seal that is connected to the upper part 206 LCD display 202. The base of the adapter is then used for mounting the housing 14, and the tabulation of the connecting cable through the cable seal. This allows you to position the housing 114 in the optimum operating position in the situation when the local user interface is located directly near each field device.
Fig.6 depicts a schematic view of the wireless unit 300 of the power and communications in accordance with a variant implementation of the present invention. Wireless unit 300 of the power and connection adapted for mounting remote from one or more field devices 14. The unit 300 includes an appropriate power production and the possibility of accumulation to power field devices 14 - simultaneous, sequential or asynchronous. It is evident from Fig.6 shows that each field device 14 is connected separately with unit 300 through the field of 112 attachment, schematically shown in Fig.6. As noted above in connection with Fig.5, the region 112 of the attachment preferably includes a local user interface, such as a command button 124 and/or the display 202. Because each field device 14 connects to the block 300 separately, with each field device 14 individually can be implemented in analog or digital communication. Although it is preferable that the user interfaces were included in the field of 112 attachment, as shown for the embodiments of Fig.6, in some embodiments, the delivery of the AI can be more, or an alternative user interface, implemented in block 300.
Fig.7 depicts a schematic view of the wireless unit 350 in accordance with another variant of realization of the present invention. Block 350 is shown with a single connection 352 to multiple field devices 14. Specialists in the art it should be clear that shown in Fig.7 configuration greatly simplifies the installation of cabling and connection of the field devices 14, block 350. For communication with the individual field devices 14 in block 350 preferably used digital communication or Protocol hybrid or fully digital standardized production Protocol. In addition, this Protocol is used to power all of the field devices 14 simultaneously, sequentially or asynchronously depending on the need. In Fig.7 also schematically shows the connection of the field devices 14 in the network using the area 112 of the fastening. Thus, each of the field devices 14 may have a local user interface that contains a local user input and/or a local user output, for example an LCD display.
Fig.8 depicts a block diagram of a wireless power and communications in accordance with the variants is realizatsii of the present invention. Block 360 includes a controller 362, the device 364 energy storage (shown as batteries), Converter 365 energy contour Communicator module 368 and 366 of the wireless interface.
The controller 362 preferably includes a low-power microprocessor and the corresponding charging circuit for supplying the necessary amount of energy from the element(s) 116 and/or from the device 364 savings for power supply 360 and all field devices connected to the region 112 of the attachment. In addition, the controller 362 also directs excess energy from the element(s) 116 on the device 364 accumulation. The controller 362 may also be associated with an additional circuit for measuring temperature so that the controller 362 can reduce the charging current through the device 364 accumulation, if it begins to overheat. Diagram of the temperature measurement may contain the corresponding sensing element, for example associated with the device 364 accumulation of thermocouple. Analog-to-digital Converter can convert the signal from thermocouple to a digital representation and to apply the digital signal to the controller 362.
The controller 362 can be configured in either hardware or software, or and so and so, for the active power distribution and for himself, and on the attached field device. Thus, the controller 32 is able to transfer himself, and any necessary field devices in eco standby mode. Standby mode is a working mode with reduced power consumption. For field devices, the standby mode may occur as a result of the team on establishing their operational current at the lowest permissible level. Events that can cause the machine enters energy saver mode, may include: after the active period, the input signal from one or more funds local user input, communicating with one or more attached field devices or wireless transmission. Such events can also be used for the output unit 360 and/or any attached field devices from standby mode. In addition, the controller 362 can selectively convert the attached field device in the standby mode for any logic or rules, as reflected in software teams within the controller 362 and/or the wireless information received through the module 366 wireless. Preferably the local input, such as a command button 124, configured by the user. Thus, the only command button can be used to output the field device from the standby mode to the user-selected period of time and at a corresponding configuration the radio again translate the field device in the standby mode. In one embodiment, the implementation of configurable local command button uses a jumper or switch to specify the following:
Command button Reduces the Active Time - selects either of 1, 1.5, 2, or 3 seconds. The field device ignores the button press duration, less specified.
The Time interval is selected either 10, 15, 30 seconds, or 5, 15, 30, 60 minutes.
If the command button is pressed twice with a small interval, then the field device remains in the mode for a specified time (for example, 60 minutes), after which it returns to the standby mode.
If the command button is pressed a second time after a specified time interval (for example, 5 seconds), then the field device returns to the standby mode.
The controller 362 preferably may also translate the parts diagram in block 360 or attached field device in standby mode. Module 366 wireless communication may be, for example, commercially available module cellular telephone System General packet radio use (GPRS), which has a normal operating mode, and standby mode. The signal from the controller 362 can transfer module 366 in the standby mode, if not guaranteed the importance of wireless messages.
Converter 365 energy can be any device suitable for conversion potential is through the energy of the environment, directly surrounding block 360, into electrical energy. In preferred embodiments of the inverter 365 is simply one or more photovoltaic elements 116. But the Converter 365 may be any other device known or developed, which is able to convert potential energy near unit 360 into electricity. Thus, the inverter 365 may include a generator with a moving element, for example, using the motion environment, the motion of the waves or wind generating electricity. In addition, for the generation of electricity Converter 365 can be thermobattery device on the temperature difference using the Peltier effect. In addition, for receiving electric power source can be used with the compressed gas or the like. Finally, in those implementations in which the energy storage devices has a relatively large capacity for a given consumer, the inverter 365 may be excluded.
Module 366 wireless connected to the controller 362 and communicates with an external wireless device via the antenna 120 on the basis of commands and/or data from the controller 362. Depending on the application module 366 of wireless devices may be adapted for osushestvleniya in accordance with any suitable Protocol wireless including, without limitation, the following: wireless network technologies (e.g., IEEE 802.11 b wireless access point and wireless network devices, developed by Linksys of Irvine, California), cellular or digital networking technologies (such as Microburst® by Aeris Communications Inc. of San Jose, California), ultra-wideband, optical free space, Global System for Mobile Communications (GSM), General Packet Radio Use (GPRS), Multiple Access, Code Division (CDMA), wideband technology, technology, infrared communication System for Transmission of Short Messages (SMS) or any other suitable wireless technology. In addition, a well-known technology prevent data conflict can be used so that many blocks will not interfere with the conditions of their mutual influence. This method of conflict prevention may include the use of multiple radio frequency channels and/or the method of expanding the range.
Module 366 wireless communication may also include transducers for a variety of methods of wireless communication. For example, the primary wireless communication can be carried out using the method regarding long-distance communications, such as GSM or GPRS, and the secondary, or additional, communications can be provided by experts or operators near unit using, for the example, technology IEEE 802.11b or Bluetooth.
Some modules of wireless communication may include a circuit capable of interacting with the Global Positioning System (GPS). The GPS system can be successfully used in block 360 for mobile devices to enable detection of individual unit 360 at its remote location. But can also be used and other methods of determining location.
It is shown in Fig.8, the storage device 370 is separated from the controller 362, but in reality it may be part of controller 362. The storage device 370 may be of any suitable type, including the device's volatile memory (RAM), non-volatile memory device (flash memory, EEPROM memory, and so on), and can also be any combination of them. The storage device 370 may include program commands for the controller 362, and any necessary service data unit 360. The storage device 370 may contain a unique identifier for a block 360, such that the block 360 was able to distinguish intended for him, wireless transmission amongst the wireless transmission. Examples of such identifiers may be a MAC address Access Control (Data), Electronic Serial Number, a global phone number, Internet Protocol (IP) or any other suitable identificator. Moreover, the storage device 370 may include information about the attached field devices, such as their unique identifiers, configuration, and capabilities. Finally, the controller 362 when using the storage device 370 may enable block 360 to provide an output signal of any suitable form. For example, the configuration and interaction with unit 360 and/or one or more attached field devices can be represented in the form of hypertext (HTML) web pages.
The synchronizer 372 is shown associated with the controller 362, but may also be part of the controller 362. The synchronizer 372 allows the controller 362 to work more efficiently. For example, the synchronizer 372 can be used to synchronize the periods indicated above in connection with configurable command button 125. In addition, the controller 362 may store information from one or more attached field devices and correlate information over time in order to identify trends. In addition, the controller 362 can complement the data acquired from one or more field devices, information about the time, before sending it through the module 366 wireless. In addition, the synchronizer 372 can be used to automatically generate periodic commands waiting/act who having increased at block 360 and/or the field device. Another option periodic synchronizer usage 372 is allowing the controller 362 to produce a module 366 pulsating signal for periodically indicating a valid status of the external wireless device.
Contour device 368 is connected with the controller 362 and negotiates the controller 362 with one or more field devices associated with one or more regions 112 attachment. Contour device 368 is a known circuit, which generates the appropriate signals to exchange information according to the above production Protocol. In those implementations in which the block 360 is associated with multiple field devices that communicate according to different protocols, it is possible that many of the contour communicators were used to enable the controller 362 to interact with various field devices. The physical connection(s)made through the region 112 attachment, allows you to block 360 to provide power to field devices and share information with them. In some embodiments of this can be done by applying power through the wires used for communication, such as two-wire circuit. But there are also options of implementing izaberete the Oia, in which power to the field device is supplied separately from the channel of information exchange. To facilitate access specialists unit 360 may include two or more terminals directly near the contour of your device 368 or region 112 attachment that facilitates the connection with the portable configuration device, such as device Model 375 Handheld, available from Rosemount, Inc. of Eden Prairie, Vinnesota.
In Fig.8 also shows an optional block 374 command button operator and an optional block LCD display associated with the controller 362. This drawing is intended to show that all local input signals from the individual field devices, the wireless unit 360 power supply and communication or both of them are connected with the controller 362. In addition, local custom displays for each field device, the wireless unit 360 power supply and communication or on both of them, are also associated with the controller 362. This allows the controller 362 to interact with each local display separately on the basis of input signals from the field device, configurable command button, attached to a field device, one or more buttons or input devices located in the vicinity of the block 360, or wireless data transfer.
Fig.9 depicts a rear view of the wireless power supply and communication with the accordance with the variant of realization of the present invention. The wireless unit 400 is associated with the field device 14 as in the previous implementations. However, the module 366 wireless and/or antenna 120 may be located in a field device 14, and not in the housing 114 of the block 400. Module 366 wireless and/or antenna 120 can be added to the field device 14 as mounted elements. In addition, the module 366 wireless communication can be an integral part of the field device 14. Thus, in some embodiments of the module 366 may be associated with the controller unit 400 through the region 112 of the attachment. In other embodiments of the module 366 may be combined with the field device, and in such embodiments of block 400 can easily provide operating power.
In the wireless power and communications in accordance with the variants of implementation of the present invention can add significant opportunities for process monitoring and control. Wireless output signal of the wireless power supplies and communication may simply be a technological parameter, but can also contain a lot more information. For example, a wireless output signal may also include diagnostic and/or operational information. In addition, the wireless power and communication may also signal the needle wirelessly about one or more field devices or even block out. The unit can send a wireless alarm signal to the same place he usually sends wireless information (e.g., control), or it can send information to an alternative object, such as a pager operator. In addition, in those implementations in which the block is associated with more than one field device, a wireless output signal can display a combination of the process parameters or the output signal of a higher level. In addition, in those implementations in which many field devices include PV generators, and one or more actuators that can change the process parameter, the blocks themselves can provide a closed image of Autonomous technology management, without interaction with the control, but only based on wireless.
Although the present invention considered in connection with the preferred variant implementation, specialists in the art it should be clear that in detail and form changes are possible, however, without deviating from the essence and scope of the invention.
