Research And Development Of UAV Ground Station Management And Control System

UAVs are widely used in aerial scenes,rescue and rescue,and high-altitude surveillance.With the rapid development and large-scale application of drones,the establishment of drones using laws and regulations,research and development and use of drone control systems is of great significance for the use of drones for the benefit of mankind.UAVs usually use wireless communication technologies such as WiFi with a small communication range,and are easily lost when the drone control distance is too long.The 4G network is gradually moving towards large-scale applications,and its wide coverage and high bandwidth characteristics provide a better choice for UAV remote communication.This topic combines 4G communication technology with UAV ground station control system to achieve ultra-remote control of UAVs in 4G signal coverage environment.The drone ground station control system can provide various functions such as data communication,flight monitoring,electronic map positioning,route planning,trajectory echoing,and automatic driving for the drone,and constitute a comprehensive platform for real-time interaction between the ground control personnel and the drone..This paper first expounds the composition and relationship of UAV and ground station systems,studies and analyzes the technical status of UAV ground stations at home and abroad,and focuses on the research status of UAV route planning methods and key technologies.Then it elaborates the key technologies for the development of the UAV ground station control system,including network programming,multi-threading technology,database application,electronic map positioning,route planning algorithm,UI development and so on.Then,according to the system function and non-functional requirements,the three-layer structure design model of data transmission layer,data management layer and user operatio n layer is designed.The data transmission layer acts as the part directly communicating with the drone,and the data will be parsed after the data is parsed.It is stored and managed by the data management layer,and the data table structure and data flow architecture are designed.Each module in the user operation layer requests the required information from the database according to the requirements.At the same time,according to the 4G network coverage characteristics and the requirements of the UAV ground station mission planning function,the heuristic search algorithm was used and improved to design the UAV route planning business process and method,and its shortcomings were analyzed and improved.The UAV route planning method aiming at the optimal 4G signal quality is designed and implemented.Finally,combined with the UAV and the onboard embedded system,the functions of the ground station system were tested one by one.The test results show that the ground station control system designed and implemented in this paper can receive and analyze the flight data of the UAV back in real time,and the functions of positioning,monitoring,route planning and historical track return can be used normally.
