[0032] The usage process in this embodiment is as follows:

[0033] See Figure 2 This is the retracted state of indicator light 6. When indicator light 6 needs to be extended... Figure 1When the train is in the "state", the telescopic rod 32 of the telescopic cylinder 3 retracts downward. This causes the connecting rod 5 to pull the rear end of the swing rod 4 downward around the hinge in the middle. The front end of the swing rod 4 and the indicator light 6 tilt upward. This allows the indicator light 6 to extend through the gap in the railing to the front side of the railing and be located above the track inside the railing. When the indicator light 6 flashes, it indicates that the train has entered the depot.

The fence 7 is positioned beside the train track 101, and the automatic retraction and extension safety indicator light 6 is mounted on the fence 7 and located between the storage location 105 and the entrance 104. The first sensor 102 is positioned near the entrance 104 to detect whether a vehicle is entering. The first sensor 102 is connected to the control module, which is connected to the telescopic cylinder 3 and the indicator light 6. Based on the entry signal fed back by the first sensor 102, the control module controls the telescopic rod 32 of the telescopic cylinder 3 to extend and lower the indicator light 6. The second sensor 103 is set on the side near the storage position 105 to detect whether a vehicle has arrived at the storage position 105. The second sensor 103 is connected to the control module. Based on the arrival signal fed back by the second sensor 103, the control module controls the telescopic rod 32 of the telescopic cylinder 3 to retract, unfold the indicator light 6, and control the indicator light 6 to flash.

[0036] The system can automatically extend and retract the indicator light 6, effectively solving the safety hazards such as delayed response and oversight in the traditional manual protection mode. While freeing up the labor of maintenance personnel, it improves the accuracy and efficiency of safety protection during maintenance operations.
