Research Of Unmanned Aerial Vehicle Remote Telemetry Ground Station System And Path Planning

With the development of science and technology,UAVs(Unmanned Aerial Vehicle)have penetrated into every part of our lives.Aerial photography,plant protection,power tours,weather monitoring,and public security systems all have UAVs and China is currently in the big wave of UAV technology research.The engine technology of the UAV body,the flight control technology of the flight control system,the wireless communication technology between the unmanned aerial vehicle and the ground station are the research hotspots of the UAV system.The entire drone system can be divided into three parts.The first part is the drone's flight control part,the second part is the data communication link,and the third part is the remote telemetry ground station.The remote telemetry ground station is an indispensable part of an unmanned aerial vehicle system.It is mainly used to receive and process drone telemetry flight data in real time,and sends some control commands to the drone from time to time,such as takeoff and hovering of flight.With the rapid development of UAVs,ground station systems are faced with numerous problems such as increasing data volume and data types,and diversification of data streams.It is imperative to improve the performance of remotely-controlled telemetry ground station systems.This topic proposes to design a remote telemetry ground station system that satisfies the basic functional requirements of the UAV system.First of all,this paper describes the research purpose and significance of this topic.And to understand the importance and the necessity for this research,this paper starts with the domestic and foreign development situation and future development trend of the remote control telemetry ground station system of UAV.Then,the related technologies of the UAV remote telemetry ground station system scheme and path planning are introduced.The ground station system introduces the basic principle and composition of remote telemetry,hardware design and software design scheme respectively.The path planning section mainly introduces some route planning threat model and algorithms.This is followed by a description of the CCSDS-compliant communication links,which main content is the CCSDS remote telemetry layering model,data format,and data encapsulation.Then describe the UAV remote telemetry ground station software part in detail,which mainly includes the user landing module,flight monitoring module,mission planning module,data management module and system debugging module.Finally,it is the research on drone path planning algorithm of obtaining the pre-planned path of drone and using B-spline to smooth path.At the end of the thesis,the work of this topic and the prospects for the future study are summarized.The design of the ground station software system is based on the Qt Creator platform developed under the linux system.It completes the development of electronic maps and serial communication in conjunction with third-party classes.And the space communication link selects the reliable and effective spatial data remote control protocol so that data can be safely transmitted.Path planning algorithm obtains static path through ant colony algorithm,and smooth of the path through B-spline theory,which makes the path practically flyable.
