Protection section configuration method, device and system for train

Abstract

The present invention proposes a train protection section configuration method, device and system, wherein the method includes: the on-board control system VOBC of the train obtains the movement authorization MA of the train from the zone controller ZC; the VOBC generates the braking curve of the train according to the MA, The braking curve is used to indicate the corresponding relationship between the train speed and the train travel distance; VOBC sends the curve parameters of the braking curve to the computer interlocking CI subsystem, so that the CI subsystem can update the train according to the curve parameters and the MA generated by ZC protection zone. The method can dynamically configure the length of the route protection section to prevent the train from rushing forward, thereby ensuring the safety of the vehicle. Since the length of the route protection section can be dynamically configured, the length of the protection section between trains can be optimized, the tracking interval of the train can be effectively shortened, and the transportation efficiency of the rail transit line system can be improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method, device and system for configuring a protection section of a train. Background technique [0002] In the urban rail transit system, due to reasons such as mismanagement of braking locomotives or insufficient braking performance, the trains will rush forward, resulting in conflicts between the rushing trains and the normal approaching trains. In the Communication Based Train Control (CBTC) mode, in order to realize the overshoot protection of the rail transit operation control system, one or more track sections are generally set outside the train parking point as the protection area of ​​the approach Segment (Overlap). Among them, the setting length of the protection zone is mainly related to various factors such as technical specifications of train vehicles, line travel time, and track laying engineering parameters. [0003] In the prior art, in order to facilitat...

AI Technical Summary

Problems solved by technology

[0004] Because in the prior art, the protection section is pre-calculated and fixedly configured in the interlock table, the degree of automation is low and the flexibility is poor

In addition, the allocation algorithm of the protection section is likely to cause the problem of low operation efficiency of the medium and low traffic rail system due to the excessive consideration of the margin
