상대제동 모델 기반 이동폐색 열차제어시스템

초록

Currently, the most advanced train control system, the moving block train control system, uses communication between onboard and wayside to track the train position and has high transport efficiency. However, it uses an absolute braking model with only the train location information, so there is a limit to improving the transport capacity. This paper proposes a relative braking model and a new movement authority structure to improve the interval control performance. The proposed model can shorten the interval by using the speed information of the preceding train to calculate the braking distance of the following train. The new movement authority consists of distance and speed information and is generated by the train. To enable relative braking, the position report and movement authority packet structure of the domestic standard (KRS SG 0069) is proposed for the movement-obstructed train control system. The interval control performance of the proposed method was compared with that of the existing system. The simulation results show that the minimum safe braking distance is improved by up to 30% based on an urban railway. It is expected that the proposed model will be utilized in the moving block train control system and standards in the future.
