摘要
介绍了基于STC89C52单片机的模拟路灯控制系统.通过安装在模拟路面的TCRT5000光电传感器实现对定位点处经过物体的精确检测,将检测的信号经单片机分析处理后控制LED灯的亮灭.采用光敏电阻来检测环境变化,自动开灯和关灯,实现对路灯运行状况的检测.该系统具有可靠性高、成本低、节能效果明显等优点.
This paper introduces a simulation of streetlight control system based on STC89C52 MCU.Through the installation of TCRT5000 photoelectric sensor in simulation pavement to achieve the anchor point goby after precise detection,the signal detected is used to control the brightness of LED lights.This control system achieves the detection of the operation condition of detection through photo resistance＇s detection of the environmental changes and automatic light up or not.The system has obvious advantages of high reliability and low-cost,energy-saving etc.
