    The invention relates to sensors. The invention also relates to valves and process control.
  • BACKGROUND OF THE INVENTION
  • [0003]
    Industrial process control environments typically require physical sensing of parameters such as temperature, pressure, flow rate, strain, displacement, humidity, vibration, etc. Adapting a sensor network and its cabling infrastructure to existing plant environments is usually cost prohibitive.
  • [0004]

    Pneumatic or fluid controlled valves are known in the art and used in a variety of applications, such as to control water and other fluids in nuclear reactors. Such valves are discussed in U.S. Pat. No. 5,197,328 to Fitzgerald; U.S. Pat. No. 6,026,352 to Burns et al.; U.S. Pat. No. 5,329,956 to Marriott et al.; and U.S. Pat. No. 5,774,048 to Achterholt, all of which are incorporated by reference. In a typical pneumatic operated valve, a current to pressure (I/P) transducer is coupled to a valve positioner which supplies an operating pneumatic pressure to a valve diaphragm actuator. The diaphragm actuator in turn is coupled to a sliding valve stem and plug. Feedback is provided by a mechanical linkage, such as by a valve positioner arm having one end connected to the actuator/valve stem and the other end coupled to the positioner so as to track movement of the valve stem. Alternatively, electrical signal feedback is provided from installed valve positioner instrumentation.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0018]
    FIG. 1 shows a system embodying various aspects of the invention. The system 9 includes a fluid control or pneumatically operated valve 10. The air operated valve 10 includes a control valve 11, a pneumatic diaphragm actuator 12, a stem coupler 13, a valve positioner 14, a pressure or volume booster 15, a controller and I/P or E/P converter 16, a sensor 17, an air regulator 18, and a pneumatic fluid supply line 19. The valve 11 controls fluid flow through a main fluid line 20. The main fluid line 20 transfers fluid in connection with an industrial process. For example, the main fluid line could transfer fluid used in a power plant (e.g., water or other fluids used in a nuclear power plant). The fluid line 20 may be any other sort of fluid line in an industrial process facility.
  • [0019]
    In the illustrated embodiment, a condition of the fluid line 20 is sensed (e.g., temperature, pressure, flow) and this information is sent to the valve positioner 14. For example, in the illustrated embodiment, the sensor 17 is a pressure transducer that senses pressure upstream of the valve 11. In alternative embodiments, different parameters can be sensed either upstream or downstream of the valve 11. In the illustrated embodiment, an electro-pneumatic type valve positioner 47 is shown, including pneumatic positioner 14 and I/P converter 16. The sensor 17 provides an output, which is an electrical output in the illustrated embodiment. More particularly, in the illustrated embodiment, the sensor 17 provides a current output. The converter 16 is coupled to the sensor (transducer) 17 and converts an electrical signal (current in the illustrated embodiment) from the sensor 17 to pressure. Other I/P or E/P converters could be employed. In some embodiments, the sensor 17 provides a signal that can be directly used by the valve positioner 14 and the converter 16 is omitted. In alternative embodiments, converter 16 can receive electrical signals from the valve position controller 39, from the sensor 17, or from both the valve position controller 39 and the process sensor 17. The valve position controller 39 is a remote controller, in some embodiments. The valve position controller 39 is a manually operable controller in some embodiments.
  • [0020]
    In the illustrated embodiment, the converter 16 is coupled to the valve positioner 14 which supplies an operating pneumatic pressure to the actuator 12. The diaphragm actuator 12 includes a diaphragm 21, and a spring 23 operating on the diaphragm. The diaphragm actuator 12 can be of a type that is opened by pneumatic fluid and closed by the spring, or can be of a type that is closed by a pneumatic fluid and opened by the spring. The actuator 12 is coupled to a sliding valve stem 24 and to the control valve 11. The spring 23 is biased between the valve stem 24 and the diaphragm 21. Feedback is provided by the actuator-valve stem coupler 13 which has one end connected to the valve stem 24 and another end coupled to the positioner 14 so as to track movement of the valve stem 24. As the valve 11 approaches the closed position, feedback is used to seat the valve 11 without slamming. The regulator valve 18 merely reduces pressure from pneumatic supply line 19 and booster 15 merely increases pressure to a level required to operate the pneumatic actuator 12.
  • [0021]
    Alternative arrangements are possible. For example, while the pneumatic actuator 12 shown in FIG. 1 is a direct-acting pneumatically operated diaphragm actuation, in which increasing pneumatic pressure pushes down on the diaphragm 21 extending the actuator stem 24, alternative actuator types could be employed. For example, in one alternative embodiment (not shown), a reverse-acting pneumatically operated diaphragm actuator type is employed in which increasing pneumatic pressure pushes up on the diaphragm and retracts the actuator stem. In another alternative embodiment (not shown), a reversible type pneumatic actuator is employed that can be assembled and installed as either a direct-acting or reverse-acting type pneumatic actuator.
  • [0022]
    Similarly, while an electro-pneumatic type valve positioner 47 is shown in FIG. 1, including pneumatic positioner 14 and I/P converter 16, alternative embodiments are possible. For example, while an analog type electro-pneumatic positioner 14 is shown in FIG. 1, a digital electro-pneumatic positioner is used in alternative embodiments. Further, in some applications a pneumatic type positioner will be used. In these embodiments, the pneumatic positioner 14 receives a pressure input signal directly from the process sensor 17 or valve position controller 166.
  • [0023]
    In some embodiments, a plurality of RFID sensor assemblies is provided to establish on-line self-diagnostic, prognostic, and calibration capabilities for the pneumatically operated valve. To instrument a component such as the pneumatically operated valve 10, individual RFID sensor assemblies are attached to monitor various parameters. Various RFID sensor assemblies may have unique sensor interfaces. More particularly, the RFID sensor assemblies include mounting structure such that the mounting and sensing is noninvasive to normal valve operation. Some such mounting structures are described below in connection with FIGS. 3 and 4.
  • [0024]
    The RFID sensor assemblies are used, in the embodiment of FIG. 1, to provide on-line or in-use self-diagnostic, prognostic, and calibration capabilities for pneumatically operated process control valves and control system components. For example, RFID sensor assemblies can be coupled to or proximate (e.g., upstream or downstream of) components such as, for example, the I/P or E/P converter 16, the valve positioner 14, the pressure or volume booster 15, the actuator spring 23, the packing of the control valve 11, and the fluid supply regulator valve 18. In FIG. 1, an RFID sensor assembly 31 is coupled to an electrical conductor 41 between the converter 16 and the valve positioner 14, an RFID sensor assembly 32 is coupled to the actuator-valve stem coupler 13, an RFID sensor assembly 33 is coupled to a conduit 22 between the booster 15 and the pneumatic actuator 21, an RFID sensor assembly 34 is coupled to a conduit 43 between the valve positioner 14 and the booster 15, an RFID sensor assembly 35 is coupled to a conduit 45 between the valve positioner 14 and regulator valve 18, an RFID sensor assembly 36 is coupled to pneumatic supply line 19 between feeds to the regulator valve 18 and to the booster 15, and RFID sensor assemblies 37 are coupled to the process line or conduit 20 on either side of the control valve 11.
  • [0025]
    The use of RFID sensor assemblies 31-37 allows for condition monitoring (e.g., periodic monitoring and data logging) of important valve performance parameters such as valve seating force, spring 23 preload and spring constant, bench set, spring packing drag or bearing friction loads, linearity of the spring 23, condition of the diaphragm 21, and valve 11 position, stroke times, and calibration. Bench set comprises compression on the spring.
  • [0026]
    In the illustrated embodiment, the system 9 further includes an RFID control tag 38, and each of the RFID sensor assemblies 31-37 communicates to the control tag 38. This is, in some embodiments, a bi-directional link so that the control tag 38 can request data from the RFID sensor assemblies 31-37 and also communicate with a reader. The system 9 further includes a reader 40 defined by, for example, a portable computer 42 such as a laptop or personal digital assistant plus an RF receiver or module 44 coupled to the laptop or personal digital assistant for communication with the laptop or personal digital assistant. Communication can be via an RS-232 link, PCMCIA connection, serial port, or other communication link. In the illustrated embodiment, the computer 42 includes software that allows for data transfer from the control tag 38 and/or the RFID sensor assemblies 31-37. The software (or separate software) permits setting up the tags.
  • [0027]
    In other embodiments, the RFID sensor assemblies 31-37 communicate directly with the reader, instead of through the control tag 38.
  • [0028]
    In the illustrated embodiment, the RF link between the reader 40 and the control tag 38 (and/or the sensor assemblies 31-37) is a low power link. For example, low power is used for transmissions. This allows the read/write range to be restricted to a predetermined range. The restricted read/write range allows for multiple networks to be placed in zones or grids, much like cell phone grids, without crossover RF interference.
  • [0029]
    The tags have individual IDs, only tags with requested IDs will respond. In the illustrated embodiment, the tags and reader operate in a frequency band that does not require government licensing such as the ISM (industrial scientific measurement) band in the U.S. or frequency bands that similarly do not require government licensing in other countries.

    The RF tags offer significant features at the sensors. The tags include microprocessors. In the illustrated embodiments, the microprocessors allow for calibration, compensation, preprocessing, and onboard diagnostics and prognostics. Each tag includes a large amount of nonvolatile memory. In some embodiments, the RFID tags are used as data loggers. The tags use the memory to periodically or at various times store data that is measured by the sensors. The nonvolatile memory is also used to store setup information that is particular to the type of sensor and the tag application requirements. For example, the time period for acquiring data is user settable (e.g., times when data is to be taken and frequency of data logging within specified time ranges). Each control tag and RFID tag included in the assemblies 31-37 has its own unique identification code or ID which is a main element in the RF protocol for communications. In some embodiments, the RF link between the reader 40 and the control tag or RFID assembly 31-37 is two way (RF reader 40 request tag to transmit). In other embodiments, the RF link between the reader 40 and the control tag or RFID assembly 31-37 is one way (tag periodically transmits to an RF reader). In some embodiments, the reader 40 is coupled to (or selectively coupled to) the Internet and defines a web server so that process reporting is performed via web pages and so that users can monitor process parameters using web browsers. Alternatively, data from the reader 40 is transferred at times to a web server 46 separate from the reader.
