Time-Stamped Emissions Data Collection for Process Control Devices
First Claim
1. A method in a process control device monitoring system, the method comprising:
- measuring, in the process control device monitoring system, one or more operating states of a process control device;
associating, in the process control device monitoring system, a time-stamp with the one or more measured operating states of the process control device, where associating the time-stamp with the one or more operating states is in response to a trigger generated based on the one or more measured operating states; and
transmitting the time-stamp and an indication of the one or more operating states to a monitoring device.

Abstract
The claimed method and system provide a process control device monitoring system and a process control valve assembly with a process control device monitoring system to measure one or more operating states of a process control device. The process control device monitoring system may also associate a time-stamp with the one or more measured operating states of the process control device in response to a trigger generated based on the one or more measured operating states. The process control device monitoring system may also transmit the time-stamp and an indication of the one or more operating states to a monitoring device.

16. A process control valve assembly comprising:
-
a valve to control a process; a position sensor to measure a position of a portion of the valve; a valve monitoring system to receive data from the position sensor, wherein the valve monitoring system is configured to associate a time-stamp with the data from the position sensor in response to a trigger, and wherein the valve monitoring system comprises a processor and a non-transitory computer-readable medium with instructions executable by the valve monitoring system; and a communications interface for transmitting data from the valve monitoring system. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
