What is the price of the Bill automatic door?
Smooth automatic door of the basic working principle is: installed in front of the door sensor infrared emission tube emitting a beam of infrared light, in the detection area to form a radiation surface, the radiation surface for the detection area, the light will be reflected in the target into this In a region, the infrared receiver detects and sends an electrical signal that reflects the red light. The signal is amplified, plastic input microcomputer. The computer according to the set procedures to command the motor and drive mechanism to work, so that the door set by the program to open, accelerate, full speed, brake slowly, close. When the door is closed when the door will be back when the obstacles, until the barrier is closed. As can be seen from the previous narrative, and then add some control components, by the controller can achieve more smooth automatic doors performance.
