Problems solved by technology

At the same time, since there is no scientific data as a judgment condition, the management of the test process is even less, and it is not convenient to accumulate test experience, and it is impossible to reuse existing test results

[0005] (2) The train transmission control software of the existing semi-physical simulation test bench has many equipments associated with the train, involving a large number of logic control and sequence control functions. The train transmission control software is the "heart" of the train. Carrying out a complete and accurate test often consumes a lot of manpower and material resources

Due to the use of manual testing, it is completely dependent on testers to check. In the process of continuous software modification, software testers need to repeat a large number of test verifications, and the correctness of the tests cannot be strictly guaranteed.

[0006] (3) There are many external objects in the train transmission control software of the existing semi-physical simulation test platform, and the joint simulation platform is constructed by means of physical or semi-physical interconnection, which is not convenient for automatic control of each system
