[0026] When in use, move the trolley 1 to a position close to the locomotive, then connect one end of the reconnection signal transmission line 6 to the locomotive external reconnection socket 5 on the host 2, and the other end to the locomotive. First, power the test device through the emergency socket DC 110V power supply, then turn on the host 2 and the LCD screen 3, and at the same time, the personnel in the locomotive driver's cab press the reconnection brake button on the locomotive to connect the locomotive to this reconnection test device, and then test the reconnection telephone 4, sand spreading instructions, emergency instructions, and network display in turn. At the same time, talk freely with the internal personnel of the locomotive through the reconnection telephone 4. The design principle draws on the telephone mode of the locomotive cab ends I and II. The operating instructions and fault handling methods required during the reconnection test can be communicated in a timely, accurate and clear manner, and the various performances of the HXD1C locomotive reconnection can be quickly tested.

[0027] Furthermore, the host 2 includes a mounting box on the outside thereof provided with a sand-spreading indicator light 7 and an emergency indicator light 8 .
