Integrated Commissioning&Test of Automatic Turn-back Function of C2+ATO Train Control System on Airport Connecting Line of Shanghai Suburban Railway
For the Airport Connecting Line Project of Shanghai Suburban Railway,this paper conducts field test verification for C2+ATO train control system with automatic turn-back function in CRRC Changchun Railway Vehicles Co.,Ltd.The test simulates the train operation according to"two stations and one section",and is equipped with real signal equipment such as train dispatching command system(CTC),computer-based interlocking(CBI),train control center(TCC),temporary speed restriction server(TSRS),ZPW track circuit and balise.The field real test is carried out to verify the after station and in station automatic turn-back function of the train.Based on the real test data,it is calculated that the average automatic end changing time is 4.4 s,and the automatic turn-back interval is 2 min30 s.The test results indicate that the automatic turn-back function of C2+ATO system successfully meets the technical requirements of automatic turn-back after station within 3 min and automatic end changing within 10 s.During the whole test process,the system runs stably,marking that the suburban railway has made technological breakthroughs and innovations in realizing high-density operation of public transit.
