Path confirmation method and device of crown block for executing emergency task

The invention provides a path confirmation method and device for a crown block for executing an emergency task, and belongs to the technical field of semiconductor transportation. The path confirmation method for the crown block for executing the emergency task comprises the following steps: inputting a task starting point position and a task ending point position to a path planning model; according to the method, each feasible path and the corresponding estimated time are obtained, then the first path with the minimum estimated time is screened, path optimization and selection are achieved, and when the target crown block travels to the first path, it is monitored that an abnormal condition exists in the track section between the target crown block and the task end point position. According to the determined feasible path and the first lane changing track section between the abnormal track section and the task starting point position, each alternative path of the target crown block starting from the first la
