Plant protection unmanned aerial vehicle flight control system

Abstract

The invention discloses a plant protection unmanned aerial vehicle flight control system, comprising a ground station subsystem, a mapping subsystem and a flight control subsystem, wherein the mappingsubsystem comprises a mapping module and a first data transmission module; the mapping module is used for obtaining takeoff and landing points of the unmanned aerial vehicle and a plurality of boundary mapping points of a target plot; the first data transmission module is used for sending the takeoff and landing points and the plurality of boundary mapping points to the ground station subsystem;the invention aims to provide the plant protection unmanned aerial vehicle flight control system which ensures safe and reliable flight of the unmanned aerial vehicle during operation by arranging a safe intermediate transit point on the flight path of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a flight control system for plant protection drones. Background technique [0002] At present, with the land transfer and the gradual scale of agricultural land production, in order to improve the efficiency of agricultural production and reduce the cost of agricultural production, there is an increasing demand for drones to spray pesticides and other operations with drones. How to safely and reliably control the flight of UAVs is an important issue in the field of UAVs. The UAV flight control method in the prior art is based on the pre-marked obstacles in the operation area, and performs obstacle avoidance design during path planning to determine the route of the UAV, and control the flight of the UAV based on the determined route. . In this kind of flight control scheme, the flight route is planned based on the marked obstacles in the operation area; in order to facilitate the...

AI Technical Summary

Problems solved by technology

In this kind of flight control scheme, the flight route is planned based on the marked obstacles in the operation area; in order to facilitate the operation, the take-off and landing points of the UAV are usually set outside the operation area. During the return process, due to the uncertainty of the return position , fly directly from the return position to the take-off and landing point outside the operation area, if there are obstacles in the flight path outside the operation area, the flight control will be unreliable
