摘　　要：激光测距雷达主要应用于测量与采集车与目标之间的距离,是汽车主动防撞系统的基础,也是关键技术之一。本文中主要设计了基于RS-232接口的LMS221型激光雷达的数据采集系统。首先介绍了串口通信的基础知识以及LMS221激光雷达的数据格式,接着介绍了激光测距雷达数据采集系统的主要技术及算法,最后对系统的各个功能模块进行了仿真与测试,经测试系统效果良好。The laser ranging radar is mainly applied to measuring and acquiring the distance between ve-hicle and target, and it is the basis of the active collision avoidance system and one of the key technolo-gies. The data acquisition system of LMS221 laser radar based on RS-232 interface was designed. Thebasic knowledge of the serial communication and the data format of LMS221 laser radar were firstly in-troduced, and then the key technologies and algorithms of the laser ranging radar data acquisition sys-tem were introduced, finally, each function module of the system was simulated and tested. The test re-sults show that the system is of good effect.
