Optimization of CTC System of Beijing- Shanghai HSR and Prospect for its Intelligence

Abstract: In view of the practical application of centralized traffic control (CTC) system of the Beijing-Shanghai HSR and in combination with the line conditions and user requirements, the system is optimized in terms of route self-triggering polling frequency, train receiving route self-triggering timing, train departure route section processing, route self-triggering between yards, wireless route forecasting and automatic train number conversion, which improves the efficiency of automatic route setting of CTC system and the adaptability of high-density and long-major lines. At the same time, according to the intelligent development requirements of railways, the paper proposes the expectation for the centralized traffic control system of the Beijing-Shanghai HSR in terms of intelligent adjustment of TWD, information sharing with traction power supply supervisory control and data acquisition (SCADA) system/disaster monitoring system, intelligent linkage of posts, etc.
