Design Of Multi-rotor UAV Ground Monitoring System

In recent years, with the multi-rotor unmanned aerial vehicles in the field of Agriculture Plant Protection and other applications is becoming more mature. As the entire command and control center of the UAV system, the UAV Ground Monitor System is becoming a hot research, Ground Monitor System which is stable and reliable for UAVs perform homework missions play an increasingly important role.In this paper, the Ground Monitor System combined with the independent development of the multi-rotor UAV has been developed based on WPF technology in the VS2013 software platform. It gives a general description of the overall structure and hardware design of the Ground Monitor System, focuses on the design of the user interface and each function module. It uses XAML to design the user interface and uses C# for logical association on the background.The communication design from the Ground Monitor System to UAV used a custom communication protocol to achieve the wireless network communication and serial communication at the same time, achieving the real-time storage data,playback data. display data, display waveform and data self-test. The GMap.NET map control is used to realize the map operation function, the trajectory planning ,the track drawing and playback function of the UAV autonomous flight are designed.Designed to achieve the sensor calibration at the ground station side, UAV flight-related parameters set in the ground station. Designed to achieve the firmware of the flight control model online upgrade on the ground station side. The article also uses DirectShow technology to deal with the video stream, realizes the multi-rotor UAV video real-time playback and camera function, to achieve the track planning is the regional boundary point of the accurate acquisition, and using the OpenGL to achieve virtual instrument construction and the 3D Model display of UAVFinally, through the Ground Monitor System and multi-rotor unmanned aerial vehicle outdoor flight test, the feasibility and stability of the each functional module of the Ground Monitoring System in this design are verified. Meeting the functional requirements and can be stable and reliable operation, to achieve the desired results.
