Research On UAV Telemetry Remote Control Ground Station And Path Planning Under Threat Network

With the rapid development of technology,drones have been widely used in military and civilian fields.As the command center of the UAV system,the ground station system has an extremely important position in the entire UAV system.It is of great practical significance to study the related technologies and development processes involved in the ground station system.This article first introduced the research background and development status of UAV ground stations and Path planning,and then introduces the basic principles and hardware software design schemes of unmanned telemetry and remote control technology;then in order to adapt the current internal transmission of UAV data transmission The type of data and the amount of data continue to increase.The CCSDS data communication link is used here,and the telemetry and remote control model based on CCSDS is introduced;the trajectory planning under threat networking is analyzed again,and the mathematical modeling of the threat networking environment is made.Use MAKLINK graph theory to construct a two-dimensional space for twodimensional trajectory planning,use the Dijkstra algorithm to obtain the initial path on the basis of the two-dimensional space,and then use the ant colony algorithm to obtain the shortest path on the basis of this path;then perform three-dimensional space modeling,Using ant colony algorithm for three-dimensional trajectory planning,and using Matlab to specify the simulation results.Finally,the telemetry and remote control ground station software is designed,which mainly includes flight monitoring,mission planning,data management and system debugging modules.The work is summarized and prospected.The design of the ground station in this article uses the Qt Creator development platform,which is based on the C++ language cross-platform graphical interface development framework.It has the advantages of fast running speed,high compatibility,and good aesthetics.It can efficiently implement the required ground station.basic skills.The ground station system uses the built-in QSerial Port class to implement serial communication in the Qt Creator development environment;the QWeb View controls is used to load Baidu offline maps to realize the development of electronic maps;the virtual instrument is developed through the Qwt component,and finally the SQLite embedded database is used to achieve Development of data management module.The interface of the ground station designed in this article is beautiful and has complete functions,and each module has achieved the expected effect.
