Abstract

The invention relates to a monitoring and analyzing system of a train communication network, and aims at analyzing and monitoring a train network signal to ensure the running safety of a train. The monitoring and analyzing system of the train communication network comprises a signal processing module, an FPGA (Field Programmable Gate Array) module and a train control system; the acquired train network signal is sequentially processed by three modules above and the obtained signal data are displayed in a display screen of the computer for a user to analyze and use.

Description

technical field [0001] The invention relates to a network monitoring and analysis system, in particular to a train communication network monitoring and analysis system. 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 occasional problems t...
