摘　　要：本系统以LED路灯为控制系统的研究对象,以STC89C51单片机为控制核心,设计了一个路灯自动控制系统。该系统利用时钟芯片DSl302计时,根据当地天黑天亮的时间对单片机进行编程设定,从而实现对路灯开关状态的时间控制;由光敏器件对环境光照度的采集,将采集信号送给单片机,当白天天气恶劣光线昏暗时,打开路灯照明。该系统具有时间控制、光敏控制相结合的路灯开关智能控制功能,同时还采用声音控制和红外控制作为辅助控制,对校园路灯乃至超市照明等其他光源的设计有参考使用价值。LED lights as the control system, STC 89C51 microcontroller as the core of the design of a street lamp control system. The system uses DSl302 time clock chip, according to the local time of night or day program setting of the microcontroller in order to achieve the status of the lights switching time control; by a photosensitive device to the ambient light collection, the collected signal sent to microcontroller, when the day bad weather, poor lighting, the open street lighting.The system has the time control, the combination of photosensitive control lamp switch intelligent control functions, voice control is also adopted as an auxiliary control and infrared control, and even the supermarket on the campus street lighting, and other reference sources to use the design of the actual value.
