Air curtain machine control system based on air valve induction

The utility model discloses an air curtain machine control system based on air valve induction, which comprises a control device, the control device is provided with a control unit, a door magnetic switch and a power key, the door magnetic switch is connected with an air valve of an air curtain machine, and the control unit is provided with a first IO port, a second IO port and a third IO port; the control unit controls a motor of the air curtain machine by configuring the first IO port to be in an output mode, and detects the states of the door magnetic switch and the power key by configuring the second IO port and the third IO port to be in an input mode. The control unit enters a standby state when powered on, and when the control unit is in the standby state, the door magnetic switch is closed, and pulse signals with the duty ratio being zero are output to the air curtain machine. The induction effect on the air valve of the air curtain machine is achieved through the door magnetic switch, when the air va
