UAV Route Planning And The Implementation Of Track Management System

Taking the large-scale campus security cruise application as the background,the subsystem of unmanned aerial vehicle cruise system----track management system was designed based on Android operating system.According to the functional requirements of the system,the aircraft management system consists of four functional modules:data communication module,data processing module,electronic map module and video monitoring module,among which the electronic map module involves online and offline Baidu map calling,track display,track playback,track planning and route modification.In order to obtain video and position-related data,the wireless communication between the track management system and the airborne system is implemented by using TCP connection-oriented socket data communication,and the flight data acquired by the airborne system was stored in SQLite database for the playback of historical tracks.The track planning algorithm was studied in this paper.After analyzing the advantages and disadvantages of the classic track planning algorithm,the A*heuristic function is introduced to improve the ant colony algorithm,avoiding to fall into local optimum,and enhancing convergence and global planning.Besides,simulation is conducted by using MATLAB to prove the feasibility of this algorithm And we realized the function of planning tracks on Android phones according to constraints in advance.Test results show that the track management system functions normally.The refresh frequency of position data from airborne system is 5Mz.And the functions of track display,track reproduction and track planning conduct well.To be short,the design purpose is achieved.
