Infrared movement and shutter control circuit thereof

The utility model provides an infrared machine core and a shutter control circuit thereof, the shutter control circuit comprises a main controller, a motor controller connected with the main controller and an energy storage circuit connected with the motor controller, the energy storage circuit comprises an energy storage capacitor, and the output end of the motor controller is connected with a shutter; when the motor controller is powered on, the main controller controls the shutter to be opened through the motor controller, and the energy storage capacitor stores electric energy. When the motor controller loses power, the energy storage capacitor releases electric energy, and the main controller controls the shutter to be closed through the motor controller. Through the arrangement of the energy storage circuit, after the motor controller is powered on, the energy storage capacitor is used for providing time delay to control the shutter to be automatically closed, so that the shutter can be intelligently cl
