Abstract
A system and method for controlling a remote valve includes temporarily driving or activating a battery-powered pilot valve assembly to place an operatively coupled output valve in a switch position. One or more processors receives a temperature measurement associated with an operating environment of the battery-powered pilot valve assembly, compares the received temperature measurement to a temperature threshold level, and continuously drives the battery-powered pilot valve assembly to maintain the output valve in the switch position if the temperature measurement is below the temperature threshold level.
Claims23
A method for controlling a remote pneumatically operated valve implemented within a process control system, the method comprising:
- receiving, by one or more processors, a temperature measurement of an operating environment proximate a battery-powered pilot valve assembly;
- determining, by the one or more processors, if the temperature measurement is above or below a temperature threshold level, wherein when the temperature measurement is above the temperature threshold,
- temporarily driving, by the one or more processors, the battery-powered pilot valve assembly to place an operatively coupled output valve in a switch position;
- ceasing temporarily driving, by the one or more processors, the battery powered pilot valve assembly;
- and wherein when the temperature measurement is below the temperature threshold,
- continuously driving, by the one or more processors, the battery-powered pilot valve assembly to thereby maintain the output valve in the switch position.
A method for controlling a remote pneumatically operated valve implemented within a process control system, the method comprising:
- monitoring, by one or more processors via an operably coupled temperature sensor, a temperature of an operating environment proximate a battery-powered pilot valve assembly;
- determining, by the one or more processors, if the monitored temperature is above or below a temperature threshold level, wherein when the monitored temperature is above the temperature threshold,
- temporarily driving, by the one or more processors, the battery-powered pilot valve assembly to place an operatively coupled output valve in a switch position;
- ceasing temporarily driving, by the one or more processors, the battery-powered pilot valve assembly;
- and
- wherein when the monitored temperature is below the temperature threshold,
- continuously driving, by the one or more processors, the battery-powered pilot valve assembly to thereby maintain the output valve in the switch position.
A system for controlling a remote pneumatically operated valve, the system comprising:
- a battery-powered pilot valve assembly operatively coupled to an output valve;
- one or more processors operatively coupled to the battery-powered pilot valve assembly;
- a memory operatively coupled to the one or more processors;
- a temperature sensor operatively coupled to the one or more processors, the temperature sensor facilitates monitoring of a temperature of an operating environment proximate the battery-powered pilot valve assembly;
- and
- a control module stored in the memory, which when executed on the one or more processors,
- determines if the monitored temperature is above or below a temperature threshold level, wherein when the monitored temperature is above the temperature threshold level,
- temporarily drives the battery-powered pilot valve assembly to place the output valve in a switch position, and cease temporarily driving the battery-powered valve assembly, and
- wherein when the temperature is below the temperature threshold level, continuously drives the battery-powered pilot valve assembly to thereby maintain the output valve in the switch position.
A tangible non-transitory computer-readable medium having instructions stored there on that, when executed by one or more processors, cause the one or more processors to:
- receive a temperature measurement of an operating environment proximate a battery-powered pilot valve assembly;
- compare the received temperature measurement to a temperature threshold level, wherein when the temperature measurement is above the temperature threshold
- temporarily drive the battery-powered pilot valve assembly to place an operatively coupled output valve in a switch position;
- cease to temporarily drive the battery powered pilot valve assembly;
- and
- wherein when the temperature measurement is below the temperature threshold,
- continuously activate the battery-powered pilot valve assembly to thereby maintain the output valve in the switch position.
