Setting Up and Research of the Dispatching System of Jing-Hu High-speed Railway

摘要

The full length of Jing-Hu high-speed railway is 1307 km from Beijing to Shanghai. There are 30 stations along the whole line. The existing Jing-Hu line will be joined with the hubs at Beijing, Tianjin, Jinan, Xuzhou, Bengfu and Shanghai. It will introduce the existing passenger stations at the above hubs and the new passenger stations to be built. In the light of specific conditions of China, the completed Jing-Hu high-speed railway will adopt the mode of alternating transportation between high-speed and mid-speed. The mid-speed trains on the existing lines will go up or down the high-speed lines at the above hubs. Thus, when the mid-speed trains running on the existing lines go up or down the high-speed lines in state of chaos, the trains running on the high-speed lines will be greatly affected, thus it will need the dispatching system on the high-speed lines and the existing lines to conduct coordinating and linking. According to the designing plan of Jing-Hu high-speed railway (TSRI, 2000), high-speed and mid-speed, mid-speed and ordinary-speed yards will be set up accordingly within the stations at Beijing, Tianjing west, and Jinan. The high-speed and mid-speed yards and mid-speed and ordinary-speed yards will share the throat. High-speed and mid-speed yards and mid-speed and ordinary-speed yards are also set up in Nanjing station, but they do not share the throat. There are no dispersing yards in the stations of Xuzhou and Shanghai. Trains have mixed use of tracks. The new Bengfu is a newly built high-speed station. Besides, on the section from Beiyuan station to Jinan station within Jinan hub, on both ends of Xuzhou station, on the section from Shanghai west to Shanghai station within Shanghai hub, the Jing-Hu high-speed railway and the existing Jing-Hu railway share the same line. Within these hubs, there are some interacting related operations between the two control systems. Thus the problem arises for the traffic control system to link up and connect between the high-speed lines and the existing lines.
