感应探测器探测到有人进入时，将脉冲信号传给主控器，主控器判断后通知马达运行，同时监控马达转数，以便通知马达在一定时候加力和进入慢行运行。

When the induction detector detects someone entering, it sends a pulse signal to the main controller. After the main controller judges, it notifies the motor to run and monitors the motor speed to notify the motor to apply force and enter slow operation at a certain time.

马达得到一定运行电流后做正向运行，将动力传给同步带，再由同步带将动力传给吊具系统使门扇开启；门扇开启后由控制器作出判断，如需关门，通知马达作反向运动，关闭门扇。

After receiving a certain operating current, the motor operates in a forward direction, transmitting power to the synchronous belt, which then transmits power to the lifting system to open the door leaf; After the door leaf is opened, the controller makes a judgment. If the door needs to be closed, the motor is notified to move in reverse and close the door leaf.
