Urban rail transit signal maintenance supporting system

Abstract

The utility model provides an urban rain transit signal maintenance supporting system, which comprises equipment centralized stations, car depots, parking bays, mobile servicing system (MSS) station equipment arranged in a control center on an urban rail transit line. MSS line maintenance center equipment arranged in the line maintenance center of the urban rail transit line communicates with all MSS station equipment on the rail transit line. MSS net maintenance center equipment arranged in the net maintenance center of the urban rail transit line communicates with all MSS line maintenance center equipment on the urban rail transit line. The system is important running equipment for guaranteeing running safety, enhancing signal equipment combination part management, monitoring the status of signal equipment, finding potential hazards in the signal equipment, analyzing fault causes of the signal equipment, assisting with fault handling, guiding field maintenance, reflecting equipment application quality and improving the maintenance level and the maintenance efficiency of signal departments.

Description

technical field [0001] The invention relates to an urban rail transit system, in particular to an urban rail transit signal maintenance support system. Background technique [0002] With the acceleration of China's urbanization process and the rapid increase of urban population, the development of urban rail transit systems with low pollution, low energy consumption, large capacity, high speed and high safety is an effective way to solve the pressure on public transportation in large and medium-sized cities. As the command center of urban rail transit operation, the signal system is an important guarantee for the safe, reliable and efficient operation of urban rail transit. [0003] Since the completion of Beijing Line 1, the urban rail signal system has experienced fixed block based on 6502 electrical concentration and analog track circuit, quasi-mobile block based on microcomputer interlock and digital track circuit, and microcomputer interlock, track circuit, etc. Next t...

Problems solved by technology

[0004] These signal maintenance support tools currently used are not coordinated with the development of urban rail transit signal system technology, and cannot meet the growing needs of users in practical applications. The performance is: 1. The urban rail signal maintenance support system still lacks dedicated technical standards, Although there are relevant standards of the mature national railway signal centralized monitoring system (signal microcomputer monitoring system) as a reference, there are large differences between the urban rail and the national railway in the signaling equipment system and signal maintenance management mode, and the national railway standard cannot be completely Meet the needs of urban rail signal maintenance; 2. Urban rail signals use a lot of intelligent signal equipment, and the advanced nature of intelligent signal equipment has not been fully utilized in maintenance and management; 3. The most important main line signal foundation in urban rail The equipment has not been monitored. Usually, the operation and maintenance quality of these signal equipment directly affects the operation safety and efficiency of urban rail; 4. There are many suppliers of urban rail signal equipment, and the standards and standards of signal equipment provided are not uniform. In the implementation stage, the signal maintenance requirements are not clear. After the system is put into use, it is very difficult and costly to adjust and modify the interface between the signal system and the microcomputer monitoring system and the types of monitoring information.
