Pathfinding method and device for M-type turnaround

Abstract

The embodiment of the present invention discloses a method and device for finding a way of M-type turning back. When the ATS plans the path for the target train, if the target train needs to pass through more than one turning point from the current position to the destination, the ATS will obtain the target train Drive to the last second turning point passed by the destination. Plan the path from the current position to each turning point step by step until reaching the second turning point, and send the planned first driving path from the current position to the second turning point to the target train, so that the target train follows the first driving path Drive to the second turning point. No new train number is allocated when the target train is running on the first driving path, and a new train number is allocated to the target train only after the target train reaches the second turning point and stops. This wayfinding method of ATS enables the target train to find its way and turn back correctly without increasing the train number.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of driving path planning, and in particular, to a method and device for finding a way of M-type turnaround. Background technique [0002] The existing principle of train turning back is: the planned train will stop and continue to find its way when it encounters a turning back, and the planned train can continue to operate after being reassigned to the train number. This turn-back logic is applicable to most stations. However, for special station types such as engineering projects, it may be necessary to go through more than one turn-back before reaching the terminal station. If you stop at the first turn-back point and continue to find the way, then It is impossible to realize the logic of more than one return, but only manual return, which reduces the return efficiency and reduces the degree of automation of return. [0003] For more than one return, the train can be assigned a n...

Problems solved by technology

[0005] The present invention solves the problem that when the existing train travels to the turn-back point, it needs to reassign the train number before proceeding to the next section of the travel path. Manual driving to reach the destination, the problem that the train cannot be automatically run to the destination without affecting the overall operation
