Valve service detection through data analysis
First Claim
1. A method for detecting a mode of operation of a valve in a process plant, the method comprising:
- receiving, at a computing device, data generated as a result of the valve operating within the process plant to control an industrial process, the valve data including respective valve parameter values of the valve for one or more valve parameters over a plurality of instances of time;
analyzing, by the computing device, the valve data to identify, from a plurality of modes of valve operation, a mode of operation of the valve, the plurality of modes of valve operation including two or more of;
full stroke cycling, continuous throttling, or periodic throttling; and
transmitting an indication of the identified mode of operation of the valve to at least one of a user interface or an application within the computing device or another computing device for analyzing operations in the process plant.

Abstract
Securing communications from a process plant to a remote system includes a data diode disposed there between that allows data to egress from the plant but prevents ingress of data into the plant and its associated systems. Process plant data from the secure communications is then analyzed to detect conditions occurring at process plant entities in the process plant using various machine learning techniques. When the process plant entity is a valve, the mode of operation for the valve is determined and a different analysis is applied for each mode in which a valve operates. Additionally, the process plant data for each valve is compared to other valves in the same process plant, enterprise, industry, etc. Accordingly, the health of each of the valves is ranked relative to each other and the process plant data for each valve is displayed in a side-by-side comparison.
