Plant-protecting unmanned aerial vehicle cluster system and plant protection method

The invention discloses a plant-protecting unmanned aerial vehicle cluster system which comprises a task ground station, an unmanned aerial vehicle ground station and a plant-protecting unmanned aerial vehicle cluster composed of N plant-protecting unmanned aerial vehicles. The plant-protecting unmanned aerial vehicle cluster is connected to the task ground station through an AD hoc network modulegroup and is connected with the unmanned aerial vehicle ground station through a data transmission module group to achieve real-time transmission of task instructions, cooperative instructions and emergency operation instructions. The plant-protecting unmanned aerial vehicle cluster system has high automation degree. In the process of a plant protection task, the task ground station can automatically complete a series of actions such as task planning, replanning, cluster takeoff, cluster task starting and cluster return and has low dependence on operators.
