Railway vehicle-mounted equipment monitoring device for network isolation communication

Abstract

The invention relates to the technical field of railway vehicle-mounted equipment monitoring, in particular to a railway vehicle-mounted equipment monitoring device for network isolation communication, which can efficiently manage all data through an FPGA (Field Programmable Gate Array) and a high-speed serial bus by performing structured treatment on different equipment data and implementing different data structures on different data contents. The purpose of safe and reliable transmission between the vehicle-mounted devices is achieved. The system has the advantages that network isolation communication among the vehicle-mounted devices is achieved, data disorder and network conflicts caused by bus mixing are reduced, the device state can be timely and effectively analyzed in real time, an existing vehicle-mounted device communication mode is improved, and a brand new communication mode is brought; high-speed transmission of data is realized, and meanwhile, the circulation security of the data is ensured; the system is simple and reasonable in structure, convenient to use and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of railway on-board equipment monitoring, in particular to a railway on-board equipment monitoring device for network isolation communication. Background technique [0002] The urban railway has the characteristics of commuting, fast speed, and large capacity. The urban railway train control system has the large capacity of urban rail transit, high-level automation, high travel speed, and interconnected operations. [0003] At present, there are many problems in the use of existing on-board equipment in China, and the maintenance interface and information volume designed in the early stage are not satisfactory for the existing maintenance use, and the systems of different models are not completely consistent, which brings great difficulties to maintenance and fault analysis. A general EMU consists of a trailer (T car), a trailer with a cab (Tc car), a motor car with a pantograph (Mp car) and a motor car with...

AI Technical Summary

Problems solved by technology

[0004] The on-board equipment of multiple systems operates independently, with many types of data and out-of-synchronization time. Each records the operation log information. When an equipment failure occurs, it is difficult to conduct effective comprehensive analysis due to out-of-synch time; the equipment is many and complex, and the maintenance personnel manually The daily maintenance workload is heavy, and it is inevitable to make mistakes due to lack of experience, and the quality of maintenance is also very random
