Unmanned cleaning task dynamic planning method and cloud server

The invention provides an unmanned cleaning task dynamic planning method and a cloud server. The method comprises the following steps: receiving road information of a to-be-operated area collected by a plurality of sweepers in a current execution period; the road information is integrated and spliced to obtain target road sections in the current execution period, all the target road sections in the current execution period form an operation grid, optimal path planning is carried out on each sweeper, and environmental sanitation operation tasks of the whole operation grid are issued to each sweeper. And thus, each sweeping vehicle executes the corresponding sanitation operation task according to the planned optimal path, and sanitation dynamic task allocation is realized. According to the invention, centralized operation management is carried out on unmanned environmental sanitation vehicles, and environmental sanitation dynamic task planning is realized by means of road acquisition, road planning, operation e
