Abstract

The invention discloses a remote switch control board for a cold air fan based on WeChat application. The remote switch control board for the cold air fan adopts WeChat remote control and is providedwith a switch circuit and a monitoring circuit, the switch circuit can quickly power down through a control circuit, turning-on and turning-off are quick and stable, and the cost is low. The monitoring circuit effectively protects a front-end circuit, and damage to an inner circuit due to interference of an external signal and surge is avoided; and the switch monitoring circuit converts an analogsignal into a digital signal, so that the working state of a switch is reliably monitored.

Description

technical field [0001] The invention relates to a control panel, in particular to a remote switch control panel for an air-conditioning fan based on WeChat application. Background technique [0002] Switching circuits are widely used in the electronics industry. When the switching circuit is turned off, if the power supply of the subsequent stage drops slowly, and if the power is turned on when the voltage has not completely dropped to a low level, the equipment connected to the power supply of the subsequent stage may not be reset correctly. . The air-conditioning fan needs to be powered down quickly to meet the needs of self-reset. [0003] In the prior art, intelligence is becoming more and more popular, and the remote control switch technology is becoming more and more mature. In the remote control technology, how to reduce the cost of the remote control technology is a problem that needs to be solved as soon as possible. [0004] Ordinary switching circuits have the d...
