초록

Train control system is a safety system that protects collision and derailment of trains by maintaining the safe interval between the leading and the subsequent trains. To protect these kinds of accidents, the train control system should conduct functions in a safe and accurate way such as train location detection, movement authority establishment, speed profile framing, and supervision/control for train speed. In general the onboard equipment of TCS detects a train location, after that transmits the information to wayside. The wayside equipment of TCS verifies the train location information and then transmits them to wayside by framing movement authority and static speed profile. The onboard equipment makes out the dynamic speed profile based on the information transmitted from wayside. With this criteria, it supervises and controls the train speed. Therefore, train location detection and movement authority establishment are more important in order to improve reliability and safety of train speed control. In this paper we present the concept design for train location detection and train movement authority settings, the definitions of interfaces and their detailed functionalities. We also propose the scheme for reliability and safety improvement.
