Each train includes 2 head cars and several middle - carriages; Head car A includes: 2 on - vehicle radio control units (MRCU) and 2 on - vehicle radio transceivers (MST); Head car B includes: 2 on - vehicle radio transceivers (MST), all of which are equipment of the train operation control system (VOCS).

[0003] There is a physical interface between the train operation control system (VOCS) and the train control system (VCS), including the connection between the positioning processing unit (ORTPR) and the on - vehicle radio control unit (MRCU), and the connection from the on - vehicle radio control unit (MRCU) to the on - vehicle radio transceiver (MST). These two connection links respectively transmit train positioning data and other radio data to the ground base station.

[0004] Since head car B is far from head car A, the 2 on - vehicle radio transceivers (MST) of head car B and the train positioning sensors on this side need to be connected to head car A through transition cables. All the above - mentioned equipment between the head cars is connected through adapters. When a fault occurs, problems such as inconvenient detection due to too long a distance or difficulty in fault judgment due to insufficient space often occur.

[0005] If the position of the faulty cable cannot be detected smoothly and quickly, it will affect train positioning, communication, and control, bringing great risks to train operation. Summary of the Invention

At the same time, considering the compatibility and convenience of the product to the greatest extent, both the first test module 1 and the second test module 2 are modularly designed. Using modular design to lead out the device interface can provide flexible and reliable detection means for the detection work in a limited maintenance space, greatly reducing the physical loss of maintenance personnel in the case of a low maintenance space and improving the convenience of detection.
