Calculation Method of Train Tracking Interval Time for Moving Block and Virtual Coupling
摘要
Abstract
Moving block and virtual coupling play a significant role in enhancing traffic capacity and optimizing transportation organization,representing the latest advancements in the field of rail transit.Given the close interconnection between moving block and virtual coupling,the calculation method of train tracking interval time during tight tracking operations is investigated.Firstly,the basic principles of train operation control and tracking operation are analyzed under 2 modes of train operation:moving block and virtual coupling.Then,for the main tight tracking operation scenarios,the calculation methods for the tracking interval distance and tracking interval time of train section tracking,train departure tracking,train arrival tracking,and train passing tracking under moving block and virtual coupling are proposed respectively,explaining the meanings and value methods of each parameter in the calculation formula.Finally,combined with actual calculation cases,taking 350 km·h-1 EMU trains and 90 km·h-1 ordinary freight trains as representatives of high-speed railways and conventional-speed railways,the tracking interval distance and tracking interval time during tight tracking operation of trains under 2 operation modes are calculated.The results show that within the virtual coupling fleet,the minimum tracking interval distance between two 350 km·h-1 EMU trains is about 5 100 m,and the minimum tracking interval distance between two 90 km·h-1 ordinary freight trains is about 1 000 m.Under virtual coupling,the tracking interval time of 4 types of trains is significantly compressed compared with those under moving block,with a compression effect of over 46.5%.关键词
