基于移动网络的多轴无人机远程控制系统

Multi-axis UAV Remote Control System Based on Mobile Network

使用4G移动网络替代蓝牙或者2.4GHz频率进行数据传输,克服目前无人机控制距离短的缺点。远程控制系统的无人机采用STM32芯片和姿态、高度等传感器相结合作为飞行控制器;采用PID作为控制算法,实现定点悬停、定高飞行等动作;采用PWM输出经过电调调节电机转速,实现对飞行姿态的调整。4G移动网络通信模块的功能是进行数据传输,完成上位机与无人机之间的通信;在上位机上实时显示无人机的地理位置、高度、周围图像等,用户可以根据上位机显示的信息,对无人机的姿态或路线进行调整,从而实现多轴无人机的远程控制。

Using 4G mobile network instead of Bluetooth or 2.4 GHz frequency for data transmission can overcome the shortcoming of short control distance of unmanned aerial vehicle(UAV).The UAV of remote control system uses STM32 chip and attitude and altitude sensors as flight controller.PID is used as control algorithm to realize fixed hover and fixed altitude flight.PWM output is used to adjust the motor speed through electronic speed control(ESC)to realize the adjustment of flight attitude.The function of the 4G mobile network communication module is to carry on the data transmission and complete the communication between the upper computer and UAV.Real-time display of UAV’s geographic position,height,surrounding image on the upper machine,users can adjust the UAV’s attitude or route according to the information displayed by the upper machine,so as to realize the remote control of multi-axis UAV.
