1、由于故障或移位，两个传感器之间出现通讯故障或无法互相通信。

1. Due to a malfunction or displacement, there is a communication failure or inability to communicate with each other between two sensors.

如果其中一个传感器出现故障或者失灵，它将发送信号给门控电机，告诉它不要关闭门。因此，如果您遇到济南车库门无法完全关闭或关闭一半又自动打开的情况，一步应该是检查传感器是否因为人为或其他原因离开了轨道，如果是，请将其重新安装回原位，并确保两个传感器之间保持水平。如果是传感器故障，就需要更换传感器。这种情况比较复杂，建议请相关人士进行维修。

If one of the sensors malfunctions or malfunctions, it will send a signal to the door control motor, telling it not to close the door. Therefore, if you encounter a situation where the Jinan garage door cannot be fully closed or partially closed and then automatically opens, the first step should be to check if the sensor has left the track due to human or other reasons. If so, please reinstall it back in place and ensure that the two sensors remain level. If it is a sensor malfunction, the sensor needs to be replaced. This situation is quite complex, it is recommended to hire relevant professionals for maintenance.

2、在传感器正常工作的情况下，它们之间存在障碍物。

2. When the sensors are working properly, there are obstacles between them.

如果传感器发射的信号在传输过程中遇到障碍物会出现什么情况呢？其中一个原因可能是，经过一段时间后，传感器的信号发射或接收镜头上积满了灰尘。因此，请用干抹布擦拭镜头，特别是镜头上的灰尘。当然，如果有其他障碍物，如存放在车库中的轮胎、扫帚甚至一片叶子挡住了传感器的信号发射路径，也可能导致门无法关闭。

What happens if the signal emitted by the sensor encounters obstacles during transmission? One reason may be that after a period of time, the signal transmission or reception lens of the sensor is covered with dust. Therefore, please use a dry cloth to wipe the lens, especially the dust on the lens. Of course, if there are other obstacles, such as tires stored in the garage, brooms, or even a leaf blocking the signal transmission path of the sensor, it may also cause the door to fail to close.

大多数情况下，当门控电机在关闭门的过程中收到“不要关闭门”的信号时，它会将门拉回打开状态，并在完全归位后发出“滴答滴答滴答”的声音，提示我们门不能安全关闭。

In most cases, when the door control motor receives a signal of "do not close the door" during the process of closing the door, it will pull the door back to the open state and emit a "click click click" sound after fully returning, reminding us that the door cannot be safely closed.

如果再次遇到这种情况，建议先简单检查家里的传感器是否存在问题或周围是否有障碍物，然后再考虑是否需要找维修人员，以免花费不必要的开销。更多相关事项就来我们网站http://www.xlmygs.com咨询!

If you encounter this situation again, it is recommended to first briefly check if there are any problems with the sensors at home or if there are obstacles around, and then consider whether professional maintenance personnel are needed to avoid unnecessary expenses.
