A calculation method of rail transit dynamic buffer zone

Abstract

A method for calculating a dynamic buffer zone of rail transit, taking the track segment being occupied as the starting track segment, and calculating all track segments in the dynamic buffer zone of the track segment being occupied according to the traveling direction of the train A traversal search is performed adding path and switch status information for all track segments in the dynamic buffer. If there is no switch, directly add the path information of the track section and the status information of the empty switch; if there is a divergent switch, add the path information and switch status information of the track section covered by the switch warning area in the order of traversal search. ; If there is a convergent switch, add the path information and switch status information of the track section covered by the switch warning area. The present invention can improve the operating efficiency of software.

Description

technical field [0001] The invention relates to a method for calculating a dynamic buffer zone of rail traffic, in particular to a method for calculating a dynamic buffer zone of rail traffic based on train behavior. Background technique [0002] During the operation of the rail transit train, the buffer zone can ensure the safe operation of the train. The buffer is divided into static buffer (static buffer) and dynamic buffer (dynamic buffer). The dynamic buffer will take into account the status of the switch in front of the train. If the current status of the switch is inconsistent with the status of the switch when the buffer route is traveling Subsequent track sections of the switch do not need to be considered. Therefore, the dynamic buffer state calculation not only improves the efficiency of train operation, but also increases the complexity of the calculation. [0003] In the existing calculation method, each track segment (block) and each track segment (buffering ...

Problems solved by technology

Therefore, the calculation of the dynamic buffer state not only improves the efficiency of train operation, but also increases the complexity of calculation.

[0003] In the existing calculation method, each orbital block (block) and each orbital block (buffering block) that may be occupied when the orbital block is passively occupied (buffered block) are all calculated. The one-to-one algorithm will cause repeated calculation of multiple paths, which will affect the efficiency of software operation
