LED智能路灯控制系统 LED intelligent street light control system  PAGE \* MERGEFORMAT V 摘 要 随着社会的快速发展，人们的生活水平也在不断的提升，在人们生活当中，自动化家用电器越来越多。与此同时，路灯也是人们生活当中不可缺少的一部分，当光线不足的楼道内或是夜晚，完全看不见路况，行走就非常不方便。 对于上面的情况，我就进行研究路灯，对于如今现有的路灯我加以分析，就决定了利用51单片机来制作一个智能路灯系统。之后就需要在51单片机上面制作相关的控制电路和软件，以实现自动控制的目标。 其中自动控制方式是红外传感和光敏检测来完成。红外传感是利用BISS0001芯片来进行的，光敏检测是利用光敏电阻来采集数据的，并且采用LM393来分析光敏电阻检测的数据并分析出光的强度。当在光线比较强的时候，该路灯是出于熄灭的状态；当光线比较弱的时候，并且没有人体的存在的时候，路灯也是处于熄灭的状态的；只有当光线比较弱的时候，同时有人体存在的时候路灯才处于亮的状态。并且在路灯亮的时候，人体离开后，延时一段时间后再熄灭路灯。这样就很好的减少了电能的浪费，也充分的体现了智能化，不用声控利用红外也减少了噪音，充分的体现了人性化。 关键词：自动感应 路灯 单片机 智能化 Abstract With the rapid development of society, peoples living standards are also constantly upgrading, in peoples lives, more and more automated household appliances.Meanwhile, the street also were an indispensable part of peoples lives, when insufficient light corridor inside or night, completely invisible road, walking very inconvenient. For the above, I conducted a study on street lights, street lamps available today for me to analyze, it was decided to make a use SCM intelligent street lighting system.Then you need to make the top 51 single-chip control circuitry and related software to achieve automatic control of the target. Wherein the automatic control mode is an infrared sensor and a photodetector to complete.Infrared sensor is the use of BISS0001 chip to carry out, the photodetector is sensitive to light and resistance to collect data and analyze the use of LM393 photoresistor test data and analyze the intensity of light.When the light is strong, when the lights are turned off for the state;When the light is weak, and there is no presence of a body, when the street is in the off state;Only when the light is relatively weak, while the presence of the human body when it is in the bright lights of the state.And bright lights when leaving the human body, the delay period of time before lights go out.This is less of a good waste of energy, but also fully embodies the intelligence, no less a voice by
