Problems solved by technology

[0003] In the prior art, the cable testing devices are all portable instruments. Before the test, the plugs at both ends of the cable to be tested need to be removed from the original vehicle-mounted equipment and connected to the portable instruments respectively, and enter the test state through manual input instructions. After the test, it is necessary to restore the wiring to the loading state at both ends of the vehicle. This method of testing requires more manpower and time, and repeated operations for a long time will also cause greater loss to the cables and connectors of the vehicle equipment. Reduce the service life of the connector and affect the communication quality of the line

Abstract

The invention provides a train WTB (Wire Train Bus-Line) communication cable detection system and a starting method thereof. The method comprises the following steps of transmitting a command to a central control unit CCU by a driver on a driver display unit DDU at one end of a locomotive through the Ethernet; sending the command to a central control unit CCU at the other end B of the locomotive by the central control unit CCU and transmitting the command to the driver display unit DDU at the end of the locomotive; after receiving the command by the driver display unit DDU, starting a WTB communication cable detection device at the B end of the locomotive and making the WTB communication cable detection device enter a ready condition; and meanwhile, after sending out the command by the central control unit CCU at one end of the locomotive for several seconds, judging whether the communication between the WTB communication cable detection device at the other end B of the locomotive is interrupted, and making a corresponding operation. Therefore, the safe and normal operation of the detection system can be guaranteed.

Description

technical field [0001] The invention relates to the field of locomotive communication detection, and more specifically, to a train WTB communication cable detection system and a starting method thereof. Background technique [0002] In the EMU, the WTB (Twisted Train Bus) communication cable that runs through the carriages is the only way to connect the locomotives at both ends for communication and control, and plays a very critical role. Once the WTB communication cable has abnormalities such as open circuit, short circuit, and poor contact If the situation cannot be dealt with in time, it will cause greater risks and huge economic losses. There is an urgent need to develop a vehicle-mounted communication cable test device to quickly measure the status and related characteristic parameters of the WTB cable, and locate the fault location of the WTB cable when an abnormality occurs, so as to help drivers and maintenance personnel quickly repair and maintain, and grasp the st...
