Study On Ground Station System Of Plant Protection Unmanned Aerial Vehicle

In recent years,eppo UAV as a result of a number of unique advantages,it has gradually become the agricultural eppo technology rookie.Ground station is as one of the most important parts of the UAV system.It has a very important significance for the UAV system use and promotion to hasa detailed research on the key principle and development process involved in it.It is necessary to design a special ground station for eppo UAV.Due to its special application scenarios and conditions of using,the ground station of the eppo UAV has more unique characteristics than the general type.This paper designs and realizes the important function of communication data link,interface display design,route planning algorithm research and data storage of sub-module.The main research contents are as follows:1.Research on route planning algorithm.According to the different regions of different route planning algorithm design.Firstly,the route planning algorithm of convex polygon region is studied.The algorithm is the basis of other kinds of regional planning algorithms.Then,the irregular regions,concave polygon regions,large region segmentation and small region simultaneous planning are analyzed.Finally,the obstacles in the region are planned to solve the obstacle avoidance problem in flight.2.Workflow design of eppo ground station system.Workflow: First of all,through high-precision handheld GPS acquisition of farmland geographic information,and then stored to the ground station My SQL database,and then through the route planning algorithm to generate regional track points,and through the MAVLink protocol will upload UAV track,the last UAV upload the waypoint to complete the flight.3.Ground station system related testing.This paper combined with the UAV ground station system debugging,verification from static test function to the simulation test,and then to the outdoor experiment,test of ground station of each function,the test results show that the ground station can receive real-time and accurate display the telemetry data,can successfully display waypoints and draw the track on the map,route planning,waypoint flight control of UAV can upload,upload to waypoint cruise flight,and the accuracy meets the requirements.
