自动化论文智能路灯控制系统设计.doc

摘 要 本设计是基于MCS-51系列单片机STC12C5A60S2和光电检测及其时钟电路设计的智能路灯控制系统，可以通过按键设置手动与自动的模式。自动模式下将一年分为三个时间段来设置早晚路灯的亮灭时间，并在其基础上通过光敏电阻对道路光照度强弱的检测控制路灯的亮灭；夜晚时，还增加了传感器检测车流量来控制路灯状态的功能。本设计具有操作简单、硬件部分稳定等特点，在道路照明正常进行的条件下，还节约了能源，是未来照明系统的首选，有很好的推广价值。 单片机；路灯；光敏电阻；照度 Abstract With the development of economy, street lighting system has become a necessary condition to ensure smooth traffic. The street lamp adopts timing control system, it cannot be guaranteed under the changing conditions of the environment on the road during the day. There is enough light to ensure the smooth passage of traffic. When the night comes, the traffic flow trough lights are always on, wasting energy. Intelligent street lighting systems make up less than before. The design of intelligent lighting control system is based on MCS-51 MCU STC12C5A60S2 and photoelectric detection and clock circuit, it can be set to manual and automatic mode by pressing a button. Automatic mode for one year is divided into three time periods to set up street lamps lit the fight time, sooner or later, and adopted on the basis of photosensitive resistance to road illumination intensity control of street lamp light ceases. During the night, it also increased the detection of traffic flow sensor to control the lamp state function. Manual mode can be manually segmented control the bright lights out, keys corresponding to different sections. Designed for simple operation and hardware features such as stability, under normal conditions of road lighting also saves energy, is the first lighting system in the future, a very good promotional value.
