Abstract
A system and method to monitor and control the valves in industrial process control and automation using Near-Field Communication (NFC) is disclosed. The system comprises a NFC-Equipment Interface Unit (NFC-EIU) to acquire parameters from the valves through a port and send the parameters to any handheld device by NFC for analysis. The NFC-EIU on receiving the analysis results from the handheld device can control the valves too.
Claims9
A system to monitor and control a plurality of valves in process control using Near-Field communication (NFC), said system comprising:
- a NFC-Equipment Interface Unit (NFC-EIU), wherein said NFC-EIU comprises of a microcontroller and a NFC module, said microcontroller configured to:
- obtain at least one parameter from at least one of a pressure valve and a flow valve through a Local Control Unit (LCU), wherein said at least one parameter comprises a Set-Reset, a Process Value (PV), a Set point Value (SP), and a Local-Remote mode;
- a handheld device connected with said NFC-EIU, wherein said handheld device is configured to:
- receive said at least one parameter from said NFC-EIU to monitor said at least one parameter;
- analyze said at least one parameter;
- and
- control at least one of said pressure valve and said flow valve based on said analysis.
A method for monitoring and controlling a plurality of valves in process control using Near Field Communication (NFC), said method comprising:
- obtaining, by a microcontroller, at least one parameter from at least one of a pressure valve and a flow valve through a Local Control Unit (LCU), wherein said at least one parameter comprises a Set-Reset, a Process Value (PV), a Set point Value (SP), and a Local-Remote mode, by the microcontroller of a NFC-Equipment Interface Unit (NFC-EIU);
- receiving, by the microcontroller, said at least one parameter from said NFC-EIU to monitor and control said at least one parameter, by a handheld device;
- analyzing, by the microcontroller, said at least one parameter, by said handheld device;
- and
- controlling, by the microcontroller, at least one of said pressure valve and said flow valve based on said analysis.
A non-transitory computer program product for monitoring and controlling a plurality of valves in process control using Near Field Communication (NFC), said product comprising:
- an integrated circuit further comprising at least one processor;
- at least one memory having a computer program code within said circuit;
- said at least one memory and said computer program code executable by at least one processor to:
- obtain at least one parameter from at least one of a pressure valve and a flow valve through a Local Control Unit (LCU), wherein said at least one parameter comprises a Set-Reset, a Process Value (PV), a Set point Value (SP), and a Local-Remote mode, by a microcontroller of a NFC-Equipment Interface Unit (NFC-EIU);
- receive said at least one parameter from said NFC-EIU to monitor said at least one parameter, by a handheld device;
- analyze said at least one parameter, by said handheld device;
- and
- control at least one of said pressure valve and said flow valve based on said analysis in said handheld device.
