Railway signal monitoring method and system

Abstract

The embodiment of the invention discloses a railway signal monitoring method and a railway signal monitoring system. The method comprises the following steps of: performing acquisition, convergence and format conversion on electrical characteristic information of equipment of the railway signal system and / or railway signal subsystem state information, adapting the information after the format conversion and a monitoring information processing module to form monitoring service data, and making a fault warning, early warning and statistical analysis interface according to the monitoring data after analysis and associated coupling. Because the embodiment adopts a uniform conversion format and is adapted to the information processing module of a fixed form, centralized monitoring of the equipment of the railway signal system is realized, the defects of decentralized management and decentralized maintenance of the railway signal system in the prior art are overcome, and a brand-new early warning mechanism and an intelligent expert diagnosis technique are provided. Because of high centralized degree, the embodiment optimizes the resource allocation of the railway signal monitoring system, and ensures corresponding maintenance efficiency at the same time of reducing the false alarm and missing alarm rate.

Description

technical field [0001] The present invention relates to the technical field of railway control, more specifically, to a railway signal monitoring method and system. Background technique [0002] Railway is an important lifeline of national transportation, and railway signaling system is the information control infrastructure supporting railway transportation. With the development of computer science and information collection technology, railway signal monitoring methods and systems have been gradually formed for the monitoring of railway signal systems. [0003] The existing railway signal monitoring methods and systems are aimed at the electrical characteristics of the signal machine, track circuit, switch switch equipment, etc. of the railway signal system, as well as the interface status between computer interlocking and train control subsystems. [0004] The inventors have found that there are at least the following disadvantages in the prior art: the existing railway ...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that there are at least the following disadvantages in the prior art: the existing railway signal monitoring system aims at decentralized management and decentralized maintenance of the railway signal system, and the repeated allocation of monitoring resources is serious

In addition, there is a lack of monitoring of key information such as the internal network structure status, module status, application software status, and interaction status between subsystems of the railway signal subsystem, and the phenomenon of false positives and missed negatives for faults is serious, resulting in low maintenance efficiency
