[0061] The range of the mimic map is the area that the drone 5 needs to explore and scan. The centralized control module 7 allocates the mimic map and the task unit to multiple drones 5. The task unit is to fly within the mimic map for a corresponding time or to complete the assigned flight range within the mimic map. After either of the two is started and completed, the drone 5 will return to the parking seat 4 by itself.
