Technical Field

[0001] The present invention relates to the technical field of rail transit, and in particular to an intelligent safety management and control system for rail transit. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. It is usually powered by electricity and adopts a wheel-rail operation mode. Rail transit is a complex system, usually composed of track routes, stations, vehicles, maintenance and repair bases, power supply and transformation, communication signals, command and control centers, etc. These components work together to ensure the normal operation of the rail transit system. According to the scope and type of service, rail transit can be divided into three categories: national railway system, intercity rail transit and urban rail transit. Among them, urban rail transit includes subways, light rails, urban express rails, modern trams, maglev transportation and other types. Rail transit safety ensures that the entire rail transit operation system controls the risk of accidents at an acceptable level under prescribed conditions. As the backbone of urban public transportation, the safe operation of rail transit is of great significance to protecting the lives and property of the people and maintaining social security and stability.
