The invention relates to a method for realizing a backup train control mode for a TACS (Tracking and Control System), which is characterized in that the backup train control mode based on trackside train occupancy detection is added on the basis of compatibility with the existing resource management of the TACS, and a resource and route management process in the backup train control mode specifically comprises a resource management process, a route management process and a route management process, the resource management module is responsible for resource verification, resource allocation, resource release and resource state registration; in the route management process, an interlocking train control module is responsible for managing a route and a related interlocking train control relation; the resource management process and the route management process run in parallel and are mutually converted, and seamless switching between the TACS main vehicle control mode and the TACS backup vehicle control mode is achieved. Compared with the prior art, the method has the advantages that the availability of the system is enhanced, and the like.
Description
technical field [0001] The invention relates to a TACS system, in particular to a method for realizing a backup vehicle control mode of the TACS system. Background technique [0002] With the help of the TACS (Train Autonomous Control System) system, the railway can realize the autonomous control of the train with on-board equipment as the main body, realize more accurate, more efficient and faster train control, simplify the trackside equipment, and improve the system performance. The railway mobile block system generally requires the use of the light-off mode of the signal machine in the TACS mode, so as to realize the tracking of the mobile block of the train and the precise control of the train running speed. However, in the case of on-board equipment failure or loss of communication with the ground, it is necessary to consider the backup vehicle control method based on the ground equipment, such as using the track circuit or axle counting as the interlocking backup mode...
