Design Of UAV Ground Control System Based On WPF

With the extensive development and application of UAVs in aerial photography,agriculture and other fields,the demand for autonomous operations of UAVs is also increasing.Research on the UAV ground control system to achieve real-time viewing of UAV flight status,trajectory planning,fault diagnosis and other functions is of great significance to promote the development of UAV industry.To this end,this paper designs a UAV ground control system based on WPF.The main work content is as follows:Firstly,according to the actual operating scenario of the UAV,analyzing the functional and non-functional need of the management and control system to give a plan for construction and function design,and complete the construction of communication link and design of the main interface.Secondly,carry out the design and development of the management and control system supervision platform.On the basis of loading the electronic map,the multi-threading technology is used to complete the data receiving and sending.Design trajectory planning algorithm to realize autonomous creation of flight mission.Based on the safety requirements of flight operations,the function of setting up restricted areas was developed.In order to achieve environmental exploration and target monitoring,complete the design of the video display module.Develop a trajectory playback function module to view the historical flight status of the UAV in order to find problems in the operation process.Thirdly,on the basis of completing the development of the supervision platform,design the management and control system data analysis platform to analyze the flight data and related log files in the database.In terms of flight data,navigation and control data can be read,and the flight status of the UAV can be analyzed and judged by comparing the target value with the actual flight data,and operational statistics can be performed by importing flight data in batches.In terms of log files,by reading the image transmission and RTK log files,the number of failed images uploaded by the image transmission is automatically calculated,and the cause of the RTK star loss is diagnosed.Finally,through the use of self-developed UAVs for flight tests,the reliability and stability of the various functional modules of the management and control system were verified,and the system requirements were met.
