Monitoring and controlling of valves in industrial process control and automation using NFC

摘要

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.

主权项

1. 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; andcontrol at least one of said pressure valve and said flow valve based on said analysis.
