When the train passes, the train contacts the track, which inevitably causes the stones laid on the track to splash, and the splashing of the probe will cause the probe to be damaged, resulting in high maintenance cost, so it has certain limitations.

This utility model detects the form state of the train through the distance sensor. When the train passes, the distance sensor transmits the sensed signal to the controller, the controller receives the signal and feeds back to the motor, so as to start the motor to run. Under the cooperation of the rotation of the extension shaft, the protection frame is rotated by ninety degrees with the one end of the extension shaft as the center, so that the infrared detector is exposed.
