Method and system for improving operation efficiency of lateral access

Abstract

The invention relates to a method and system for improving the operation efficiency of a lateral access. The method comprises the following steps of: setting a speed-up transponder in an external section of an incoming signal, setting lateral access data to be predicted by the speed-up transponder, acquiring the lateral access data when vehicle-mounted equipment passes through the speed-up transponder, wherein the lateral access data comprises a line speed information packet and a temporary speed limit information packet, determining the minimum value of speed values in the line speed information packet and the temporary speed limit information packet as a target speed limit value, and driving into the lateral access with the target speed limit value. The system comprises a layout module,the speed-up transponder and the vehicle-mounted equipment. According to the method and the system for improving the operation efficiency of the lateral access, the train can receive the lateral access data in advance, acquire temporary speed limit information and line speed information in the lateral access data, and effectively improve the running efficiency of the train of the lateral access.

Description

technical field [0001] The invention belongs to the field of rail transit communication signals, and in particular relates to a method and a system for improving the operating efficiency of a lateral approach. Background technique [0002] In the existing CTCS-2 and CTCS-3 train control systems, the low-frequency code sequences UU and UUS in the block zone have speed meanings respectively. The code requires the train to run at a limited speed (the default turnout lateral allowable speed is 80km / h); [0003] When there is a temporary speed limit or a fixed speed limit lower than 80km / h on the sideways incoming road, the train control system controls the three-closed zone to send the UU code, and the second close-blocked zone sends the U2 code; the on-board equipment enters the second close-blocked zone After receiving the code U2 sent by the track circuit, the allowable speed of the lateral approach is obtained in advance, and the allowable speed is used as the target speed ...

AI Technical Summary

Problems solved by technology

[0007] When the train is running in the section, the on-board equipment uses the main line wireless message data received in advance. When the signal in the front station opens the lateral route, the on-board device cannot receive the lateral route data in advance, and the train only passes the incoming signal. Only the transponder at the train station can receive the data of the lateral approach. The target speed of the on-board equipment driving to the signal machine at the station is at least 0km / h or 25km / h, which leads to a very low driving efficiency of the lateral approach of the train.
