A method and system for comprehensive operation and maintenance of rail traffic signals based on cloud computing

Abstract

The present invention relates to a method and system for integrated operation and maintenance of rail transportation signals based on cloud computing; using the four-level model of railway corporations, railway bureaux, electrical service depots, and stations, in the railway corporations and rail bureaux, respectively deploying a data centre, a data acquisition device, and a terminal, and in the electrical service depots and the stations, only deploying a data acquisition device and a terminal; also deploying a real-time data analysis component, the real-time data analysis component in the electrical service depots or stations being deployed in the data acquisition device, and the real-time data analysis component in the railway corporations or railway bureaux being deployed in the data centre. The present invention uses a hierarchical mode of deployment, implementing real-time analysis of signal data by means of directly deploying a real-time data analysis component in an acquisition device, meeting the storage demands of ever-increasing signal data by means of a tiered storage and indexing strategy, and implementing rapid locating of a fault by means of a four-layer indexing structure; the signal data corresponding to the time of a fault can be rapidly retrieved by means of information including the time, type, and position of the fault.

Description

technical field [0001] The present invention provides a method and system for comprehensive operation and maintenance of railway signals based on cloud computing, involving railway signal data, railway communication data, railway knowledge data, system alarm data, machine learning, vehicle-mounted equipment, station equipment, central equipment, and trackside equipment and other technical fields to solve the problems faced by the comprehensive operation and maintenance of railway signals. Background technique [0002] At present, there are three main types of monitoring and maintenance products in the communication and signal fields of rail transit (state-owned railways, enterprise railways and urban rail transit): CSM (Centralized Signal Monitoring System), various equipment maintenance machines, and communication network management systems for ground signal equipment. In order to improve the modern maintenance level of my country's railway signal system equipment, since th...
