The reason why the rolling shutter door of garage has a large dynamic opening is that the remote control of garage door selects the triple system (3-phase) for the purpose of transmission. They are equipped with printed circuit boards based on crystal or submerged arc welding to meet severe EMC requirements. The remote controls (types 94335e, 94330e and 94333e) are equipped with two 3V lithium batteries (CR2032). The battery life is five years. When the remote control is activated, it generates a pulsating radio signal.

当开门机中的接收机拾取到信号时，它把信号与存储的代码作比较。接收机验证编码两次。假设它承受代码，则会建议开门机。接收机解码器的照应时刻为0.3秒-从建议遥控器到翻开车库门。

When the receiver in the door opener picks up the signal, it compares the signal with the stored code. The receiver verifies the code twice. Assuming it bears the code, a door opener is recommended. The receiver decoder takes care of 0.3 seconds - from the recommended remote control to the garage door.

电动车库门翻开动态大的原因剖析

Analysis of the reason for the dynamic opening of electric garage door

1.合页、轨迹等的固定螺丝松动。查看固定合页和导轨的螺丝看是否松动，如有松动，用老虎钳上紧

1. The fixing screws of hinges and tracks are loose. Check the screws that fix the hinge and guide rail to see if they are loose. If they are loose, tighten them with a vise

2.设备车库门时，没有保持在一个水平方位，门板一边靠近轨迹，另一边远离导轨，导致门体上升过程中，门板上的铰链和导轨之间冲突力增大，然后发生吱吱的噪音。解决方法，调整两端导轨，确保门板在两端导轨正中间。

2. When the garage door is installed, it is not kept in a horizontal position. One side of the door panel is close to the track, and the other side is far away from the guide rail. As a result, the collision force between the hinge on the door panel and the guide rail increases, and then squeaking noise occurs. The solution is to adjust the guide rails at both ends to ensure that the door plate is in the middle of the guide rails at both ends.

3.门板侧边铰链上面悉数涂上润滑油，特别留神铰链和轨迹对应的那一周围面、铰链孔内部都要加润滑油

3. All the hinges on the side of the door panel shall be coated with lubricating oil, especially the surrounding surface corresponding to the hinge and track, and the inside of the hinge hole
