Intelligent embedded automatic smoke proof screen control system with remote radio control

摘要

The utility model releases an intelligent automatic smoke proof screen control system with remote radio control, in which the transforming and rectifying circuit is connected to 220V AC power supply and outputs positive and negative 24V voltage to the rectifying circuit to generate 5V DC voltage; the 5V DC voltage is used to respectively power the CPU circuit, remote radio control signal reception circuit, motor driving and control circuit and smoke proof screen lift/drop control circuit; the DC positive and negative 24V voltage is used to power the smoke proof screen lift/drop control circuit; the central processing circuit is connected to the smoke detection signal input interface to receive smoke alarm signals; the central processing circuit delivers control instructions based on the received smoke detection signal and remote radio control signal, and the motor driving circuit receives such control instructions and actuates the smoke proof screen to lift or drop. The control system reduces economic loss, is easy to use and can meet the needs in practical application.
