Train network control system semi-physical comprehensive simulation test platform and test method

The invention relates to a train network control system semi-physical comprehensive simulation test platform and a test method. The test platform comprises a simulation control system, an input and output module and a test piece. The simulation control system comprises a control unit and an equipment simulation unit. The input and output module comprises a communication interface module, a logic controller and an adjustable power supply. The equipment simulation unit is connected with the communication interface module, the logic controller and the adjustable power supply through a communication interface module, a controller interface module and a power control interface module respectively. The output end of the input and output module is connected with the test piece. The test platform of the invention is a comprehensive test platform, can be applied to a variety of protocols and provide a variety of power supplies and is wide in applicability. The test platform can not only be used for test and detection of train network control equipment and related equipment, but also can be used for online debugging of a whole train network. The time for real train test is reduced, the development cycle is shortened, the on-vehicle debugging time is shortened, and the cost of research and development is lowered.
