文档介绍：基于单片机的太阳能庭院灯设计
摘要
能源问题仍旧是当今的一个主要问题,开发利用太阳能资源是解决此问题的一个有效办法,在我国发展太阳能光电照明系统具有重要意义。本文介绍了太阳能庭院灯的工作原理,采用了89C51单片机作为智能控制系统,该系统中有蓄电池充满检测电路、过放电保护电路、过流保护电路。即使电压和温度过高,电池也不会因为过充电而损坏,从而有效的延长了系统部件(特别是蓄电池)的使用寿命。实现了太阳能电池板白天给蓄电池充电,晚上自动给负载供电的目的,所设计的家庭庭院灯有很好的实用价值。

Design of Solar Garden Lamp
based on Single-Chip puter
ABSTRACT
The energy issue is still a major chanllenge to tackle one currently. It is an effective way to solve this problem by exploiting and utilizing the solar resource. It is has significant meaning in our country to develop the photoelectric lighting system of solar energy.
This article introduces the operation principle of the courtyard light powered by solar energy, which has adopted 89C51 single-chip puter as the intelligent control system has a storage battery which fulls is consisted of circuit, protecting circuit for over-discharging,electricity protecting circuit for over-flowing of electricity and so on. When the battery discharged and temperature is too high, the system has very good automatic protection functions to the battery , the battery will not be damaged , and the service life of the effective systematic parts (especially the battery ) of extension. It realizes the mechnism by charging the storage battery in the daytime and supplying power for the appliance automatically in the ,the courtyard lights designed is practical.
Keywords: solar, 89C51, single-chip puter, intelligent control, battery
