Abstract
A remote fault monitoring system for an electric valve includes: an MCU, a hydrogen sulfide sensor, a hydrogen sensor, a pull-press sensor and an actuating mechanism; the pull-press sensor is connected with an A/D conversion interface of the MCU by a signal amplifier, the hydrogen sulfide sensor and the hydrogen sensor are connected with the A/D conversion interface of the MCU by respective signal transmitters, and a D/A conversion interface of the MCU is connected with an opening-degree control port of the actuating mechanism by a voltage-to-current transmitter. An opening in-place signal and a closing in-place signal of the actuating mechanism are connected with a GPIO input interface of the MCU, and a GPIO output interface of the MCU is connected with an opening control port and a closing control port of the actuating mechanism by actuating mechanism relays.
