System and method for monitoring and controlling a target operating device of a process control system

摘要

A method of monitoring and controlling a target operating device of a process control system. The method comprises: detecting activation of one or more parts of the target operating device with a sensor of a wireless latching unit; latching a switch of the wireless latching unit from an active state to an inactive state upon detecting the activation of the one or more parts; transmitting one or more active signals from the wireless latching unit to abuse station upon latching the switch to the active state; detecting deactivation of the one or more parts of the target operating device with the sensor of the wireless latching unit; ignoring the detected deactivation at the wireless latching unit; and continuing to transmit the one or more active signals from the wireless latching unit to the base station. A wireless monitoring and control system is also disclosed.

1. A method of monitoring and controlling a target operating device of a process control system, the method comprising:
detecting activation of one or more parts of the target operating device with a sensor of a wireless latching unit; latching a switch of the wireless latching unit from an inactive state to an active state upon detecting the activation of the one or more parts; transmitting one or more active signals from the wireless latching unit to a base station upon latching the switch to the active state; detecting deactivation of the one or more parts of the target operating device with the sensor of the wireless latching unit; ignoring the detected deactivation of the one or more parts of the target operating device with the wireless latching unit; and continuing to transmit the one or more active signals from the wireless latching unit to the base station after the detected deactivation until receiving a termination signal from a second source that the wireless latching unit has been reset to an inactive state.
