Drive decoupled plant protection unmanned aerial vehicle control system and control method

Abstract

The invention relates to a drive decoupled plant protection unmanned aerial vehicle control system and a control method. The control system includes a plant protection comprehensive management module, a height control module, a navigation control module, and a spray control module. The plant protection comprehensive management module is configured to manage the interactive function of navigation, spray operation, height control and parameter setting. The height control module is configured to measure the distance between the unmanned aerial vehicle and the crop canopies, and to maintain the height of the unmanned aerial vehicle, and reduced the droplet drift caused by the influence of natural wind, and ensured the operation effect. The navigation control module is configured to control the unmanned aerial vehicle to flying along the preset operation route. The spray control module is configured to control the operation switch in accordance of the position of the unmanned aerial vehicle, and effectively avoid leakage spray and pesticide spray. The present invention realized the autonomous flight control of the plant protection unmanned aerial vehicle, the decoupled drive of the vertical lift and horizontal thrust guaranteed the simple and reliable of the control system, and reduce the labor intensity of operators.

Description

technical field [0001] The invention belongs to the field of agricultural aviation plant protection, and relates to a control system and control method for driving and decoupling a plant protection UAV platform, so that it can carry out plant protection operations along a preset flight route, maintain the operation height, and avoid pesticide leakage, spraying, etc. Heavy spray or severe droplet drift. technical background [0002] Compared with the traditional manual spraying of pesticides in the field, the spraying of pesticides by plant protection drones has very obvious advantages: the efficiency of drones is high, the harm of pesticides to operators is small, and the labor intensity of operators is greatly reduced. The droplet drift is less, the penetrability of the fog flow to the crops is significantly enhanced, and the control effect on diseases, insect pests and weeds is good. The drone does not need a special lifting site, and the maneuverability is good. At the s...
