The Construction Plan Research and Verification of Simulation Testing Platform for Train Control System Engineering of High-speed Railway.

High-speed railway train control system has high safety level, various equipment components, complex functional structure and interface relationship, and great difficulty in dynamic inspection. By using the simulation test technology, it will completely rely on the on-site integrated commissioning and test, and be completed through the implementation of simulation test. It can further improve the test coverage and reduce the impact on transportation. On the basis of researches on the necessity of project construction, construction objectives and technical solutions, specific researches are carried out on ground equipment, on-board equipment, simulation system plan, etc. Through comparison and selection, the ground equipment of simulation testing platform for train control system engineering of the high-speed railway adopts the semi-physical and semi-simulation structure, and uses the cloud platform technology, which has better scalability and economy. The on-board equipment adopts the completely real equipment, which improves the credibility and authenticity of the test. Through the construction of simulation testing platform and the verification based on the simulation environment of Huzhou -- Hangzhou High-speed Railway, the research results show that compared with the field test, the simulation test has completed more scenarios, cases and route tests, and their numbers have increased by 275%, 336% and 442% respectively, which can further improve the quality, depth and breadth of the train control system test.
