Description

technical field [0001] The invention relates to a train signal control system, in particular to a simulation verification method and device for a TACS system. Background technique [0002] The full name of TACS is Train Autonomous Circumambulate System, which is an autonomous train operation system based on the train-to-vehicle communication system. The TACS train control system technology based on vehicle-to-vehicle communication, with its flexible management of trackside resources and savings in subway construction costs, can also have fully automatic driverless functions. TACS technology has gradually become the next-generation train in the rail transit industry. The development direction of control technology. Compared with the traditional "vehicle-ground-vehicle" communication link and control architecture, TACS has broken through the bottleneck of the traditional train control system architecture, making train control significantly improved in terms of safety, flexibi...

AI Technical Summary

Problems solved by technology

[0004] 1. Construction period, input cost and occupied space: the construction of a TACS test line for vehicle-to-vehicle communication is equivalent to the construction of a small subway main line, and the construction of civil engineering, power supply, signal and vehicles needs to be considered. The construction period Long, high input cost, need to plan and occupy more land resources, and the space occupancy rate is huge

[0005] 2. Insufficient expandability of multi-professional interface: TACS train control system line is a multi-professional fusion subway line, which is composed of basic professional equipment such as vehicles, signals and power supply

Because it is in the real test line environment, adding new professional equipment has insufficient interface scalability and low flexibility. There are many situations and factors that need to be considered, and there are great resistance and difficulties in project implementation.

[0006] 3. The scene functions to be verified are limited: TACS technology based on vehicle-to-vehicle communication, as a new subway line operation mode, will also have fully automatic driverless functions

Due to the authenticity of the test line, it is difficult to flexibly simulate fault scenarios and emergency scenarios, which leads to the limitation of verification scenarios and functions in the environment of the test line

[0007] 4. The problem of verification work efficiency: the test line uses real subway line equipment. Since the start-up and operation of real equipment require preparation time, it is often switched from one verification scene to another, which involves more real The equipment needs to be restarted, the train position needs to be restored, and the verification method of the all-physical system used in the test line has inherent shortcomings, which greatly affects the verification efficiency of the vehicle-to-vehicle communication TACS system function

[0008] 5. The problem of high maintenance costs: The real test line equipment itself has a service life. After multiple rounds of sports car experiments and functional verification, the trains and line equipment of the test line need to be regularly maintained and maintained, which requires a lot of manpower. Material and financial resources, high maintenance costs
