The new-type train control system is the latest research direction of train operation control system in China.The new-type radio block center is the core ground equipment of the newtype train control system.It calculates movement authority and sends it to trains in real-time and controls train operation safely.To ensure the quality and safety of the new-type radio block center and identify its functional defects as far as possible in the laboratory simulation stage,it should be tested and verified adequately.Based on the analysis of the new functions of the new-type radio block center,the test method based on the simulation test platform for the new-type radio block center is studied.Combined with the real engineering data of the Ruoqiang—Hetian line,the test scenarios that may occur during actual train operation are designed to test and verify the functions of train occupancy inspection and OS authority generation.The test results show that the designed test scenarios fully consider the combination of laboratory simulation test and field real data,and can meet the verification requirements of the new-type radio block center.
