Rail traffic signal comprehensive operation and maintenance method and system based on cloud computing

Abstract

The invention relates to a rail traffic signal comprehensive operation and maintenance method and system based on cloud computing. The mode of four stages including a railway company, the railway administration, an electrical service section and a station is adopted, the railway company and the railway administration are respectively provided with a data center, a data acquisition device and a terminal, and the electrical service section and the station are only respectively provided with a data acquisition device and a terminal; meanwhile, real-time data analysis components are deployed, the real-time data analysis components of the station and the electrical service section are deployed in the data acquisition devices, and the real-time data analysis components of the railway administration and the railway company are deployed in the data centers. A hierarchical deployment mode is adopted for the rail traffic signal comprehensive operation and maintenance method and system, signal data can be analyzed in real time by directly deploying the real-time data analysis components on the acquisition devices, the requirement for storing continuously increasing signal data is achieved through a hierarchical storage and indexing strategy, and faults can be fast positioned through a four-layer indexing structure, and corresponding signal data in the faults can be fast retrieved through information such as time, types and positions of the faults.

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...
