摘　　要：设计了一种激光雷达数据远程采集系统,由STM32微处理器、思岚RPLIDAR A1激光雷达、Lo Ra无线数传电台和PC端组成。利用IAR开发平台实现STM32微处理器由串口1采集激光雷达数据,并通过串口2连接到Lo Ra无线数传电台,将数据传输至PC端。采用QT Creator编写PC端串口接收界面程序,实时显示接收数据,通过计算可以得出距离和角度数据,获得周围环境的情况。A long-range lidar data acquisition based on Lo Ra is presented in the paper,which is mainly composed of STM32 microcomputer,lidar module,wireless data transceiver and PC.Using the IAR development platform the lidar data collected from the serial port one by the STM32 microcomputer is achieved,and then the data is transmitted to the LoRa wireless data transceiver from serial port two.The serial port GUI data receiving program of windows in PC is written by Qt language,and the receiving lidar data is showed in time.When the distance and angle of the lidar data are computed,the surroundings are clear.
