When pushing operation is handled, a shunting locomotive is positioned at the tail of a train, and a driver cannot master the running state in front of the train in the process of advancing the train, so shunting personnel (tie members) are required to be positioned at the front of the train to observe, and the driving safety can be ensured. When a train to be connected before the train runs, in order to ensure that the running speed of the train is within a safe and controllable range, a shunting person (a connector) also needs to timely convey the distance between the train and the train to be connected to a crew member so that the crew member can reduce the speed (ten trains: 110m, the speed is controlled below 17km/h, five trains: 55m, the speed is controlled below 12km/h, three trains: 33m, the speed is controlled below 7km/h, and some stations also need to convey the distance of one train, namely 11m), and the process is called displaying distance signals of ten, five and three trains. Therefore, whether the connector can correctly display the distance signals of the ten, five and three vehicles is an important index for finishing the pushing operation, if the distance signals cannot be accurately displayed, the train stops and releases air without reaching a set position, so that delay accidents are caused to influence the shunting operation efficiency, and if the distance signals cannot be accurately displayed, the train is hung continuously at a high speed, so that the train body can be damaged, and even the life safety of shunting personnel is endangered.
