How does the automatic door work?
The automatic door system consists of sensors, controllers, motors, rails and doors. The sensor is now mostly microwave sensors, the equivalent of a radar, when there is a movement near the object, it sends a signal to the controller. Controller is generally used PLC programming microcomputer, we can adjust the controller through the door to open the door when the speed. The controller controls the operation of the motor and the motor is connected to the door by means of a toothed belt and a door connection (connected by a hanging part). There is a pulley on the hanging part. The door is hung on the guide rail by a pulley on the hanging part Can slide. The rails are fixed on the beams and the beams are firmly connected to the walls on both sides. The gravity of the door is supported by the guide rail, and the belt pull door slides left and right on the rail
