Analyzing method of main track trafficability of urban rail transit in moving block

Abstract

The invention discloses an analyzing method of urban rail transit movement blocking main track trafficability, comprising the following steps of: A, respectively generating a time-distance curve of a front car tail and a rear car head with preset departure interval under the condition of barrier-free operation in a coordinate system with distance as a horizontal coordinate and time as a vertical coordinate; and B, calculating the minimum main track tracking interval corresponding to each point on the time-distance curve of the rear car head according to the time-distance curve of the rear car head and the front car tail, and generating a main track tracking interval curve. Furthermore, the influence on capability caused by the limit condition of interlocking or operation is further considered, thereby making the output result closer to the reality. The invention not only improves the scientificity and the accuracy of the analysis on the main track trafficability of the urban rail transit in a moving block system, but also lowers the difficulty, the complexity and the development cost of the analysis on the track trafficability of the urban rail transit in the moving block system.

Description

[0001] Technical field [0002] The invention relates to the technical field of rail traffic control, in particular to an analysis method for the passing capacity of a moving block main line of urban rail traffic. Background technique [0003] The mobile block system means that it is not necessary to divide the section into fixed block partitions, but to automatically adjust the running interval between two trains to keep a certain distance between them. Thereby greatly improving the passing capacity of the section. The basic technical feature of moving block is that it has two-way safe data communication between the train and the ground. It makes full use of advanced communication transmission means to carry out two-way communication between the train and the ground in real time or regularly, so that the subsequent trains can know the actual distance between the trains ahead in time. The following trains can calculate the optimal braking curve, which not only improves the tr...

Problems solved by technology

[0017] In view of the fact that the analysis method of the main line passing ability of the current urban rail transit is not scientific and accurate, and the required workload is large and the development cost is high, the technical problem to be solved by the present invention is: how to provide a train that can carry the whole main line of the train through The analysis method of the passing capacity of the main line of the mobile block system of urban rail transit based on the capacity analysis not only improves the scientificity and accuracy of the analysis of the passing capacity of the main line of the mobile block system of the urban rail transit, but also reduces the passing capacity of the main line of the mobile block system of the urban rail transit.
