when the working mode is the automatic mode, the MCU outputs a low level to the optocoupler 2 to switch on the relay K2 based on the received door opening signal, the electromagnetic lock is electrified through a pin 2 of an interface J1 to further execute the unlocking action of the electromagnetic lock, and after the unlocking action is kept for the delay time, the MCU outputs a high level to the optocoupler U2 to further execute the locking action of the electromagnetic lock;
when the working mode is the manual mode, the MCU outputs a low level to the optocoupler 2 to switch on the relay K2 based on the received door opening signal, the electromagnetic lock is powered on through a pin 2 of an interface J1, the unlocking action of the electromagnetic lock is further executed, and when the door opening signal is not detected, the optocoupler U2 outputs a high level, and the locking action of the electromagnetic lock is further executed.
