AI Technical Summary

Technical Problem

In urban rail transit, the train operation plan lacks flexibility, which leads to the train degradation or stopping when the train and the ATS communication failure or the forward line or the forward train fails, which affects the overall operation efficiency.

Method used

By obtaining the operating path unit, initial position and target position of the target train, selecting the candidate path unit based on this information, and selecting the target path according to the path selection strategy, to achieve flexible planning of the train operation path.

Benefits of technology

The operation efficiency of the target train is improved, ensuring that the train can flexibly adjust the path when a communication failure or obstacle ahead occurs, avoid downgrade or stopping, and improve overall operation efficiency.

Abstract

The invention provides a path planning method and device, and the method comprises the steps: obtaining a running path unit of an associated target train, and determining an initial position and a target position of the target train; and selecting candidate path units in the running path units based on the initial position and the running direction of the target train, and constructing at least one candidate path comprising at least one target path unit based on the target position and the candidate path units. And selecting a target path for the target train in the at least one candidate path according to a path selection strategy. In the running process of the target train, at least one candidate path can be constructed for the target train according to the initial position and the target position of the target train, and then the target path can be selected from the at least one candidate path according to the path selection strategy. The target train can run according to the target path, flexible planning of the running path of the target train is achieved, and the running efficiency of the target train is improved.
