Problems solved by technology

The time-space variation characteristics of faults in the high-speed train information control system during operation, as well as the isolation characteristics brought about by system redundancy, modularization or plug-in packaging, etc., make it impossible to achieve normal operation behavior on the traditional hardware-in-the-loop simulation platform. The architecture of a large-scale and complex fault diagnosis application verification platform is constructed simply by setting fault injection links or adding fault diagnosis functions; it is also impossible to simulate the evolution environment of system faults and their occurrence, development, and failure in the fault injection mode. Therefore, it is very difficult to realize the effective control between fault testing / injection behavior, impact and isolation, and it cannot meet the requirements of system-level fault injection and fault diagnosis implementation technology application verification research, and it will also bring problems to platform equipment. destructive, harmful to test personnel and other hidden dangers

[0005] Most of the existing high-speed train simulation platforms aim at simulating, simulating, and verifying the normal operation behavior of high-speed trains. They can only simulate abnormal working conditions in some subsystems or functional modules offline and manually, and “failure-oriented safety "Fault-stopping behavior under the mechanism
