Power-off type valve control anti-interference circuit applied to wireless instrument of Internet of Things

The utility model discloses a power-off type valve control anti-interference circuit applied to a wireless instrument of the Internet of Things. The power-off type valve control anti-interference circuit comprises the wireless instrument, a valve of the wireless instrument, a valve driving module and a driving circuit. The driving circuit is arranged at the grounding end of the valve driving module, a control device in the driving circuit is disconnected when the valve does not need to be controlled, and a current loop of the valve driving module is cut off. According to the utility model, by adding the MOS tube control circuit, the power consumption is reduced, and the anti-interference capability is enhanced; an MOS tube control pin is led to a switch in-place detection control pin, so that MCU pins are saved. 本实用新型公开了一种应用于物联网无线仪表的断电式阀门控制抗干扰电路，包括无线仪表及其阀门、阀门驱动模块、驱动电路；在所述阀门驱动模块的接地端设置所述驱动电路，在不需要控制阀门的时候断开所述驱动电路中的控制器件，切断所述阀门驱动模块的电流回路。本实用新型通过增加MOS管控制电路，降低功耗，增强抗干扰能力；将MOS管控制引脚引到开关到位检测控制引脚，节省了MCU引脚。
