Abstract

The present invention relates to the technical field of electronic circuits, and discloses a switch control circuit and a switch control system, wherein the control circuit includes: a plurality of parallel signal processing units, the signal processing unit has a first controllable switch; the first controllable The first end of the switch is connected to the first voltage signal, the second end is connected to the first port of the controller, and the third end is connected to the second voltage signal; the first voltage signal and the second voltage signal control the first control the on and off of the switch, and convert the first voltage signal into a third voltage signal; the third voltage signal is connected to the first port of the controller; the controller is configured to , and send the switch control command to the terminal to be controlled. After converting the high strong electric signal into a low stable weak electric signal, the circuit combines the controller to realize multi-channel switch control, and only processes the voltage signal in the whole circuit, avoiding the processing of various types of signals and ensuring the multi-channel Reliability of switch control.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a switch control circuit and a switch control system. Background technique [0002] The operation of the power switch of the electrical equipment is generally controlled locally by the user, and can only be operated at a fixed position, and can only be operated when the user needs to go to the side of the electrical equipment. [0003] With the improvement of people's living standards and quality, the types of electrical equipment on the market are increasing, and people's requirements for the intelligence of electrical equipment are getting higher and higher, and the intelligence of power switch control of electrical equipment is particularly important. The above-mentioned control method for electrical equipment requires the user to go to multiple electrical equipment in turn to manually control the power switch of each electrical equipment in some occasions where th...
