System and Method for Monitoring and Controlling a Target Operating Device of a Process Control System
First Claim
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 with the wireless latching unit; and
continuing to transmit the one or more active signals from the wireless latching unit to the base station.

Abstract
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.

7. 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; and continuing to transmit the one or more active signals from the wireless latching unit to the base station until receiving a termination signal from a second source. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A wireless monitoring and control system comprising:
-
a base station comprising a base processor and a base memory; a target operating device comprising one or more parts; a wireless latching unit communicatively coupled to the target operating device and the base station, the wireless latching unit having a latch processor, a latch memory, an interface for transmitting data associated with the wireless latching unit to the base station, a sensor for detecting activation and deactivation of one or more parts of the target operating device, and a switch adapted to be latched to an active state upon activation of the one or more parts of the target operating device; a module stored in the latch memory of the wireless latching unit and executable by the latch processor to;
(1) detect activation of the one or more parts of the target operating device;
(2) latch the switch to the active state when activation of the one or more parts is detected;
(3) instruct the interface to transmit one or more active signals from the wireless latching unit to the base station; and
(4) ignore deactivation of the one or more parts of the target operating device until receiving a termination signal from a second source that the wireless latching unit has been reset to an inactive state. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A system comprising a processor, a computer readable storage medium, and computer-executable instructions stored on the computer readable storage medium and executable by the processor to:
-
detect activation of one or more parts of the target operating device with a sensor of a wireless latching unit; latch 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; transmit one or more active signals from the wireless latching unit to a base station upon the switch being latched to the active state; detect deactivation of the one or more parts of the target operating device with the sensor of the wireless latching unit; ignore the detected deactivation at the wireless latching unit; and continue to transmit the one or more active signals from the wireless latching unit to the base station until receiving a termination signal from a second source.
