Embodiment 1

[0269] Taking the downlink capacity analysis of the section from Beijing South Station to Jinan West Station of the Beijing-Shanghai high-speed railway as an example, the analysis method of the present invention is used to quantitatively analyze the integration capabilities of each bottleneck link and interval station under the CTCS-2 / CTCS-3 level, Validate the validity of the analytical method. The specific implementation process is as follows:

[0270] 1. Data preparation for the four aspects of line infrastructure, train model, signaling system and operation organization

[0271] (1) There are 6 stations and 2 line stations along the Beijing South-Jinan West section: Beijing South, Langfang, Beijing-Tianjin Line Station, Tianjin-Shanghai Line Station, Tianjin South, Cangzhou West, Dezhou East, and Jinan West.

[0272] (2) Take CRH380B(BL) and CR400BF as examples for analysis.

[0273] (3) Combining the characteristics of different CTCS levels and the workflow of CTCS-2 an...

Abstract

The invention relates to a capability analysis method suitable for a high-speed railway. The method specifically comprises the following steps: A, preparing data in four aspects of line infrastructure, a train model, a signal system and operation organization parameters; B, according to different access types, dividing partition divisions, specifically, dividing the partitions into five types including a train receiving partition, a train departure partition, a station track partition, an interval partition and a line place partition; C, establishing different types of partition block time models under CTCS2 level and CTCS3 level based on the signal system workflow and in combination with different operation scenes; D, analyzing the capacity of a bottleneck link in operation of the high-speed railway, namely analyzing the capacity of the convergence line where the bottleneck possibly occurs from two indexes, namely the worst train interval and the worst average minimum train interval,of a station; and E, carrying out capability analysis on the section station integration to obtain a most unfavorable section station integration operation plan.

Description

technical field [0001] The present invention relates to the technical field of rail traffic control, in particular to a capability analysis method suitable for high-speed railways under CTCS-2 and CTCS-3 levels, and in particular to a high-speed railway bottleneck link capability under CTCS-2 and CTCS-3 levels Analysis method of section-station integration capability. Background technique [0002] The Chinese Train Control System (CTCS) is the key technology and core equipment to ensure the safety of high-speed railways and improve the transport capacity. The construction and operation have played an important role. Both of them use the entrance of the block zone occupied in front as the end point of the traffic permit, adopt the quasi-moving block method, and the train occupancy check is realized by the track circuit. The information transmission characteristics of the CTCS-2 train operation control system are that the train occupancy information is transmitted through the...
