Embodiment 1

[0062] Such as image 3 As shown, it is a schematic flow chart of Embodiment 1 of the communication fault detection method provided by the present invention, which specifically includes the following steps:

[0063] S101. The power line controller 3 receives a network communication detection instruction;

[0064] S102. The power line controller 3 obtains the device identifiers of all communication devices in the TCMS communication network and records them in the first list;

[0065] S103. The power line controller 3 selects the first communication device as the central communication device, and sends the first switch 11 control command to the network control module 10 of the central communication device;

[0066] S104, the network control module 10 of the central communication device receives the first switch 11 control command, and opens the first switch 11 and the second switch 12 and closes the third switch 13, and throws the first double-throw switch 15 to the first port ...

Embodiment 2

[0080] This example is in image 3 Combining on the basis of the first embodiment Figure 4 The network control module 10 of the central communication device determines the flow diagram of the proximity relationship between the communication devices in the first TCMS communication network and Figure 5 The shown network control module 10 of the central communication device determines the schematic flow diagram of the adjacent relationship between the communication devices in the second TCMS communication network, and the first embodiment is described in detail, specifically including the following steps:

[0081] S201. The power line controller 3 receives a network communication detection instruction;

[0082] S202. The power line controller 3 acquires the device identifiers of all communication devices in the TCMS communication network and records them in the first list;

[0083] S203. The power line controller 3 selects the first communication device as the central communi...

Abstract

The invention provides a TCMS communication system and a communication failure detection method. The TCMS communication system has good flexible control performance and is convenient for failure detection. The communication failure detection method is provided on the basis of the TCMS communication system. By determining adjacency relation between communication devices in the TCMS communication system, according to the adjacency relation of the communication devices, failures of the TCMS communication system can be quickly detected and locations of the failures can be accurately located.

Description

technical field [0001] The invention relates to the technical field of vehicle control and management, in particular to a TCMS communication system and a communication fault detection method. Background technique [0002] As the speed of subway trains increases, the structure of trains becomes more and more complex, which puts forward higher requirements for the safe, reliable and efficient operation of trains. Therefore, subway or train fault detection and diagnosis system has become an essential and important part of modern subway or train. The subway and train fault detection and diagnosis system is an intelligent system that can effectively diagnose train faults in a short period of time through prompts or man-machine business dialogues when a subway or train has a fault or is about to break down during operation. [0003] Such as figure 1 As shown, it is a schematic diagram of the TCMS communication system in the prior art. When a communication failure occurs in the e...
