## 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.

## Claims

### Claim 1

A system to monitor and control a valve in process control using Near-Field communication (NFC), wherein said system comprises:
an NFC-Equipment Interface Unit (NFC-EIU), wherein said NFC-EIU comprises a microcontroller, a NFC module;
at least one valve connected with said NFC-EIU;
a handheld device connected with said NFC-EIU;
wherein said system is configured to:
obtain parameters from said at least one valve using said NFC-EIU;
send said parameters to said handheld device by said NFC-EIU;
analyze said parameters by said handheld device; and
control said at least one valve by said NFC-EIU based on said analysis, on said NFC-EIU receiving said analysis from said handheld device.

### Claim 2 (depends on 1)

The system as in claim 1, wherein said at least one valve comprises: a pressure valve, a flow valve.

### Claim 3 (depends on 1)

The system as in claim 1, wherein said system is configured to integrate with existing valve by implementing said NFC-EIU to internal modules of said at least one valve.

### Claim 4

A Near-Field Communication (NFC)-Equipment Interface Unit (NFC-EIU) for monitoring and controlling a valve in process control using NFC, wherein said NFC-EIU comprises a microcontroller, a NFC module, further said NFC-EIU is configured to:
acquire parameters from at least one valve in said process control;
send said parameters to a handheld device for analysis; and
control said at least one valve based on said analysis, on said NFC-EIU receiving said analysis from said handheld device.

### Claim 5 (depends on 4)

The NFC-EIU as in claim 4, wherein said NFC-EIU is configured to acquire said parameters and control said at least one valve using wired communication.

### Claim 6 (depends on 4)

The NFC-EIU as in claim 4, wherein said NFC-EIU is configured to send said parameters to said handheld device and receive said results from said handheld device by NFC using said NFC module in said NFC-EIU.

### Claim 7

A method for monitoring and controlling a valve in process control using Near Field Communication (NFC), wherein said method comprises:
obtaining parameters from at least one valve using a NFC-Equipment Interface Unit (NFC-EIU);
sending said parameters to a handheld device by said NFC-EIU;
analyzing said parameters by said handheld device; and
controlling said at least one valve based on said analysis by said NFC-EIU from said handheld device.
