遥控车库门原理是怎么设计的？

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.

车间门系统采用无线遥控电路和霍尔传感器，用单片机控制电机，从而实现了自动车库门的各种功能。红外发射信号源，感应器接收信号，弱电控制系统，工作部分电机带动卷帘门卷起，将电机反转。电机、传动链轮及控制部分组成。

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.

与此同时，该系统有一个超音波开关，而且事实上，其中一部分是超声波感应，当你的汽车平稳进入这个范围时，就能达到这个开度。

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.

本系统还包括上下两个开关，其状态从闭合到打开，触到下限开关之后，与上限原理相同。

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.

维修车间门可安装防盗、安全系统：如降遇阻尼系统，使门体在阻停时，既保护人身和车辆安全，又保证可靠使用；红外感应控制系统，有效保障人员、车辆、宠物的进出安全；防盗报警系统，当有人撬门时，高音喇叭会发出警报，保护安全。待机时，蓄电池可同时切断电源，无需手动开门。

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.
