The garage door is automatically controlled by microcomputer program and operates automatically through the remote controller. The principle is scientific. The built-in torsion spring makes the door body in the "zero weight" state. It rotates by pulley in the track, so the resistance is small and has good dynamic performance. Ring transformer, planetary gear on and off, Hall element induction and pulse. We need a motor to support the remote garage door, but the current used is also what we often call AC. Friends who study physics know that it needs to connect the positive and negative power supplies. When the motor rotates, the garage door will rise, otherwise it will fall.

車間門系統采用無線遙控電路和霍爾傳感器，用單片機控制電機，從而實現了自動車庫門的各種功能。紅外發射信號源，感應器接收信號，弱電控制系統，工作部分電機帶動卷簾門卷起，將電機反轉。電機、傳動鏈輪及控制部分組成。

The workshop door system adopts wireless remote control circuit and Hall sensor, and the motor is controlled by single chip microcomputer, so as to realize various functions of automatic garage door. Infrared transmitting signal source, inductor receiving signal, weak current control system, working part motor drives the rolling shutter door to roll up and reverse the motor. It is composed of motor, drive sprocket and control part.

與此同時，該系統有一個超音波開關，而且事實上，其中一部分是超聲波感應，當你的汽車平穩進入這個范圍時，就能達到這個開度。

At the same time, the system has an ultrasonic switch, and in fact, part of it is ultrasonic induction. When your car smoothly enters this range, it can reach this opening.

本系統還包括上下兩個開關，其狀態從閉合到打開，觸到下限開關之后，與上限原理相同。

The system also includes upper and lower switches, whose state is from closed to open. After touching the lower limit switch, it is the same as the upper limit principle.

維修車間門可安裝防盜、系統：如降遇阻尼系統，使門體在阻停時，既保護人身和車輛，又保證可靠使用；紅外感應控制系統，有效保障人員、車輛、寵物的進出；防盜報警系統，當有人撬門時，高音喇叭會發出警報，保護。待機時，蓄電池可同時切斷電源，無需手動開門。

The door of the maintenance workshop can be equipped with anti-theft and safety systems: if the damping system is encountered, the door body can not only protect the safety of personnel and vehicles, but also ensure reliable use; Infrared induction control system can effectively ensure the safety of personnel, vehicles and pets; Anti theft alarm system, when someone pries the door, the tweeter will give an alarm to protect safety. During standby, the battery can cut off the power supply at the same time without opening the door manually.
