[Abstract]:In recent years, the four-rotor UAV has been widely used in the fields of military reconnaissance, disaster monitoring, geographic mapping, aerial photography and so on because of its strong mobility, high flexibility and low cost. As the command center of UAV system, ground monitoring system can monitor the flight status of UAV in real time, manage the UAV flight control, study the key technology and realization method of ground monitoring system. It is of great significance to the flight safety and mission execution quality of the whole UAV system. Aiming at the shortcomings of low practicability of track planning and poor reusability of system software platform in track planning of ground monitoring system for four-rotor UAV, this paper takes the ground monitoring system of four-rotor UAV as the research object. Combined with the actual functional requirements of the system, the hardware platform of the system is built. The cross-platform graphical interface framework QT is used as the development platform of the system software and functions, and the FFmpeg codec library, Open GLG Qwt graphics library and Google map electronic slicing technology are combined. A four-rotor UAV ground monitoring system with complete function, friendly interface and cross-platform is designed. Firstly, the overall scheme of ground monitoring system is designed. According to the actual function requirement of the monitoring system, the hardware equipment, the function module structure of the system software and the function layout of the software interface are designed. Then, according to the function design of the monitoring system software, the design and implementation process of the main function modules are introduced in detail. The first is the design and realization of the communication function, the communication protocol between the four-rotor UAV and the monitoring system, the receiving and processing of serial communication data, the realization process of aerial video capture and data storage; The second is the realization of data display and data processing, including the rendering of flight virtual instrument, the visualization of flight attitude and flight trajectory, the function of flight playback and the realization of drawing data analysis curve. Thirdly, the function of off-line map and track planning is designed. The display structure and coordinate conversion algorithm of off-line map are designed in detail, and the basic operation function of route planning is designed. Finally, through the online test with the four-rotor UAV, the functions of the monitoring system software are tested as a whole. The test results show that the ground monitoring system works stably and reliably, and the ground monitoring system software can be applied and deployed across the platform, and can accurately receive and display the monitoring data and aerial video of the four-rotor UAV. The aerial video can be compressed and stored, the flight attitude and trajectory can be visualized and displayed normally, and the flight monitoring data can be drawn and displayed by curve when analyzing the data. The off-line map is able to respond correctly to operations such as point and track planning.
