Background technique

Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned paraglider etc. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, low requirements for combat environment, and strong battlefield survivability. Since unmanned aircraft is of great significance to future air combat, all major military countries in the world are stepping up the development of unmanned aircraft. In November 2013, the Civil Aviation Administration of China (CA) issued the "Interim Regulations on the Management of Civilian Unmanned Aircraft System Pilots", and the Chinese AOPA Association is responsible for the management of civil drones. According to the "Regulations", the operation of drones in mainland China can be divided into 11 situations according to the size of the model and the flight airspace. Among them, only drones weighing more than 116 kilograms and airships weighing more than 4,600 cubic meters fly in the integrated airspace, which is managed by the Civil Aviation Administration. In other cases, other flights, including the increasingly popular micro-aerial aerial vehicles, are managed by industry associations or the operators themselves are responsible.

The plant protection drone is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flying platform (fixed wing, helicopter, multi-axis aircraft), navigation flight control, and spraying mechanism. It can be controlled by ground remote control or Navigate the flight control to realize the spraying operation, which can spray chemicals, seeds, powders, etc.

At present, the plant protection UAV is flying according to the established route, and cannot communicate with the background in real time. If the operation path needs to be changed, manual adjustment is required, which affects the operation efficiency.
