【摘要】 介绍了基于AT89S52的激光雷达门控控制系统的工作原理,并着重讨论系统硬件和软件的实现方法。系统采用AT89S52单片机为核心,配置以数字电位器、光电耦合器、单稳态触发器等部件,控制光电倍增管门控开关的时间,从而实现对激光雷达测量的起始点和结束点的实时调控。更多还原

【Abstract】 The principles and methods of a controlling system based on AT89S52 applied for gating control system of lidar are intro-duced in this paper and described the realizing approaches of both the hardware and soft ware in particularly.The AT89S52 single chip microcomputer is used as the kernel component of this system and the other parts are digital potentiometer and photocoupler and monostable multivibrator which control the timing for the gating of the photomultiplier tube,then enable a more precisely and rea-sonable management towards start point and end point in the measure of lidar.更多还原
