摘　　要：设计的路灯控制系统以STC单片机作为主控MCU,使用时钟芯片、串口通信、按键、液晶显示、等模块构成支路控制器,用单片机(STC12C08AD)作为单元控制器,使系统能根据设定时间和环境明暗变化自动开灯、关灯以及故障声光报警。在检测行人情况(物体移动检测)方面,本系统通过红外信号发射光来进行检测,通过串口通信告知单元控制器,点亮和关闭LED。系统通过支路控制器与单元控制器的结合,实现了精确的电路调控,同时,电路的性价比和效率高,功耗小,从而实现了节能并高效。This streetlight control system is mainly controlled by microcontroller （STC）, using the clock chip, serial communication,buttons, LCD, and other modules constitute a slip controller to microcontroller （STC12C08AD） as a cell controller, so that system can set the timing and the circumstances under shading changes automatically turn on the lights, turn off the lights and sound and light alarm failure. Detection of traffic conditions （objects, motion detection）, the present system through the infrared light to carry out detecting signal transmission through the serial communication inform the cell controller, light on and off LED. The system controller and cell controller through the slip road to the combination of the circuit to achieve a precise control, while the circuit cost and high efficiency, power consumption, thereby helping to achieve energy-saving and efficient.
