Abstract

The invention provides an agricultural plant protection unmanned aerial vehicle (UAV) planting control system which is composed of a vehicle-borne subsystem and a ground station subsystem. The vehicle-borne subsystem comprises a vehicle-borne GPS antenna (1), a vehicle-borne relative height detector (2), a vehicle-borne obstacle detector (3), and a vehicle-borne data returning and receiving system (4). The ground station subsystem comprises a ground station geographic information system (5), a ground station flight task planning and flight control system (6), and a ground station instruction receiving and sending system (7). According to the system of the invention, work currently needing vehicle-borne flight control is transferred to the ground, the air control part is only responsible for stability augmentation and obstacle detection, and a lot of path computation and flight control operation are managed and controlled by the ground in a unified manner. Therefore, the weight of the vehicle-borne system is reduced greatly, the difficulty in UAV developing is reduced, and the operation requirements of a variety of UAVs are satisfied effectively.

Description

technical field [0001] The invention belongs to the technical field of agricultural drones, and in particular relates to an agricultural plant protection drone sowing control system. Background technique [0002] Plant protection UAV is a kind of unmanned aircraft used for agricultural and forestry plant protection operations. It is generally composed of three parts: flying platform, GPS flight control and spraying mechanism. The spraying operation can be realized through ground remote control or GPS flight control. It can spray Drugs, seeds, powders, etc. It can load 8-10 kg of pesticides and spray pesticides at low altitudes. Its spraying efficiency is 30 times that of traditional manual operations. At the same time, it will not cause pesticide residues and pollution, effectively protecting agricultural operators. [0003] The existing plant protection UAV sowing control system not only has a unit on the UAV that receives GPS information, detects the height of the UAV, an...
