M-type turn-back path finding method and device

Abstract

The embodiment of the invention discloses an M-type turn-back path finding method and device. The method includes the steps that when an ATS plans a path for a target train, if the target train needsto pass through one or more turn-back points from a current location to a destination, the last second turn-back point through which the target train passes before travelling to the destination is acquired; the path to each turn-back point is planned section by section from the current location until the second turn-back point is reached, and the planned first traveling path from the current location to the second turn-back point is sent to the target train so that the target train can travel to the second turn-back point according to the first travelling path; when the target train travels according to the first travelling path, no new train number is distributed, and only after the target train reaches the second turn-back point and stops stably, can a new train number be distributed tothe target train. By means the ATS path finding method, correct path finding can be conducted to realize turn-back without adding a new train number to the target train.

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
