SWITCH CONTROL CIRCUIT AND SWITCH CONTROL SYSTEM
First Claim
1. A switch control circuit, comprising:
- a plurality of parallel-connected signal processing units, the signal processing unit having a first controllable switch;
the first controllable switch having a first terminal connected to a first voltage signal, a second terminal connected to a first port of a controller, and a third terminal connected to a second voltage signal;
the first voltage signal and the second voltage signal controlling turning-on and turning-off of the first controllable switch, and converting the first voltage signal into a third voltage signal; and
the third voltage signal being connected with the first port of the controller; and
the controller, configured to send a switch control instruction to a to-be-controlled terminal based on the third voltage signal.

Abstract
A switch control circuit and a switch control system includes a plurality of parallel-connected signal processing units. A first voltage signal and second voltage signal control turning-on and turning-off of the first controllable switch, and converting the first voltage signal into a third voltage signal; and the third voltage signal being connected with the first port of the controller; and the controller, configured to send a switch control instruction to a to-be-controlled terminal based on the third voltage signal. This circuit converts a electrical signal of a high voltage in strong electricity into a stable electrical signal of a low voltage in weak electricity, implements multiplex switch control in conjunction with the controller, and only processes voltage signals in the whole circuit, thereby avoiding processing signals of a plurality of types, and guaranteeing the reliability of the multiplex switch control.
