Abstract

The invention relates to a method and system for fault detection and analysis of a train communication network, which ensures safe operation of trains through analysis and monitoring of train network signals. Described a kind of train communication network fault detection and analysis system comprises signal processing module, FPGA module and train control system, and the train network signal that gathers passes through above-mentioned three modules successively and the signal data after processing is displayed on the computer display screen for user Analytics use.

Description

technical field [0001] The invention relates to a network monitoring and analysis system, in particular to a fault detection and analysis method and system for a train communication network. Background technique [0002] With the rapid innovation of science and technology, the modern train control system has developed from a centralized direct digital control system to a network-based distributed on-board computer control system. Therefore, the fault detection technology of train communication network has become one of the core technologies of modern train control system. At present, my country's train communication network maintenance methods are still at a backward level. The previous train network system was mainly provided by foreign manufacturers, and they were also overhauled and maintained accordingly. In recent years, with the gradual use of domestic network systems, there is no mature solution for the supporting repair and maintenance equipment, especially for the...
