Design of train integrity monitoring system for radio based train control system

Radio based train control system can perform the high density train control due to its real-time traceability of train location and the high amount of information transmission, and it has the merit to reduce costs for equipment invetment and maintenance costs because it does not use the existing track circuit. However, a separate system which can check the train integrity on a real-time basis is required since it does not use the track circuit. This paper proposes a train integrity monitoring system which can check the real-time train integrity in the radio based train control system. For the safe protection of parted train, it is possible to monitor parted situations of train on a real-time basis by using separate onboard equipment. This paper describes system requirements for the design of proposed TIMS, system configuration and the operation algorithm.
