基于北斗定位的无人机可视化监测方法

Visual monitoring method of UAV based on Beidou Positioning

针对目前研究的无人机可视化监测方法存在监测精度和可靠性较低的问题,提出了基于北斗定位的无人机可视化监测方法。通过北斗定位导航芯片和无线射频模块中核心元件芯片,采集可视化数据。同时检测前导码、同步字、数据包长、传输地址、有效数据、CRC校验数据包,确定ADDR寄存器可以调整的地址类型。分析PC机与无人机操作终端之间的运作流程,根据Socket函数与本地IP和端口相关联,完成可视化数据监测。实验结果表明,基于北斗定位的无人机可视化监测方法能够修正历史数据的匹配结果,提高监测的精准性和可靠性。

Aiming at the problems of low monitoring accuracy and reliability in the currently studied UAV visual monitoring method,a UAV visual monitoring method based on Beidou Positioning is proposed.Collect visual data through Beidou Positioning and navigation chip and core component chip in radio frequency module.At the same time,the preamble,synchronization word,packet length,transmission address,valid data and CRC check packet are detected to determine the address type that can be adjusted by ADDR register.Analyze the operation process between PC and UAV operation terminal,and complete visual data monitoring according to the correlation between Socket function and local IP and port.The experimental results show that the UAV visual monitoring method based on Beidou Positioning can correct the matching results of historical data and improve the accuracy and reliability of monitoring.
