1、 毕 业 设 计(论文) 题目： LED 光伏太阳能照明系统设计 院（系） ：院（系） ： 电气工程学院电气工程学院 专业班级：专业班级： 电气电气091 学学 号：号： 学生姓名：学生姓名： 指导教师：指导教师： 20132013 年年 6 6 月月 1818 日日 I 摘 要 本文设计了一种具有时控和光控相结合的太阳能路灯控制器，利用单片机 STC89C51 和时钟芯片 DS1302 控制路灯照明时间，利用低功耗的数据存储器 24C02 存储路灯点亮和熄灭时间，利用光敏电阻实现光电控制。傍晚光线暗时控 制器自动接通路灯电源，深夜行人少时根据设置的时间熄灭路灯，早上再自动接 通电源点亮路灯、
2、天亮后自动关断。文中详细分析了控制器的电路组成和工作原 理，简述了控制器的调试过程。 太阳能路灯系统的控制器是整个路灯系统中充当管理者的关键部件，它的最 大功能是对蓄电池进行全面的管理，防过充电控制，防过放电控制。过充控制， 就是在蓄电池处于过充状态时断开充电电路，过放控制电路就是在蓄电池处于过 放状态时断开放电电路。过充、过放控制都是为了保护蓄电池，延长蓄电池的使 用寿命。 太阳能路灯由太阳能电池、蓄电池、高亮度 LED, 控制器等部件组成，减少 噪声污染：太阳能路灯运动部件很少，基本没有噪声。 关键词：关键词：太阳能电池；LED；铅酸蓄电池；时控、光控电路；充放电控制器 II Abstra
3、ct This paper designed a solar street lamp controller with time control and light control combination, controling street lamp lighting time by using STC89C51 MCU and clock chip DS1302 ,using low power data storage to storage the time of lighting lamps and extinguished lamps,achieving photoelectric c
4、ontrol by Photoresistor .In the evening when the light is dim street lamp controller automatically switch on the power, when the late night pedestrian less according to set time extinguished lamp, morning auto power on light, dawn after the automatic shutdown.

5、s detailed analysed in the paper and resume the debugging process of the controller. Controller of solar street lighting system is a key component of the street lamp management system , its biggest function is to manage the storage battery, prevent charging control, prevent excessive discharge contr
6、ol. Charge control, is in the battery is charging state is disconnected from the charging circuit, a control circuit is to disconnect discharging circuit when the storage battery is in the overdischarge state , prolong the service life of the battery. Solar street lamp is composed of a solar battery, battery, high brightness LED, and other components, reducing noise pollution: solar street lamp has few moving parts, no noise. Key words: solar battery; LED; lead-acid
