There are many kinds of automatic electric doors, taking the net flower electric door as an example, it is the use of the relationship between the three sides of the triangle, the change of the right Angle side, so that the net flower under the action of driving, linkage telescopic. Drive the head, in the magnetic field induction control of the controller, the controller and control of the motor forward and reverse, to achieve the drive head correction, stop control. In addition, anti-collision, anti-crawl, Bluetooth control, electronic induction control and other functions. Working principle of the automatic door sensor: when the automatic door sensor detects someone entering, the pulse signal will be transmitted to the main control device, which will inform the motor to run after judging, and monitor the motor revolution at the same time, so as to inform the motor to redouble force and enter the slow operation at a certain time. After the motor gets a certain running current, it runs forward and transmits the power to the synchronous belt. Then the synchronous belt transmits the power to the spreader system to make the door fan open. After the door is opened, the controller will make judgment. If the door needs to be closed, the motor will be notified to move in reverse and the door will be closed.
