下载后可任意编辑摘 要太阳能光伏发电是一种不需燃料、无污染猎取电能的高新技术。充分利用太阳能不仅可以节约日益减少的不可再生能源，又可以减少对环境的污染，这使太阳能成为现在社会的一种重要能源。太阳能 LED 路灯，是太阳能应用在现实生活中的实例，近几年受到普遍的关注与讨论。本论文设计了一种智能太阳能 LED 路灯系统，以 AT89S51 单片机为核心，通过对光强的检测和蓄电池电量的检测，再由单片机实现设定功能。本文内容包括国内外太阳能发电现状及工作原理，方案选择，元器件选择，系统的硬件，软件设计及系统的改进方向。其中系统的硬件设计主要包括单片机最小系统、蓄电池充放电控制电路、主副电路的电压变换电路、A/D 转换电路、主副电路切换电路、光强检测电路、电量检测电路、系统与上位机通信电路和温度检测等设计。关键词太阳能 LED 路灯 光强检测 电量检测Abstract：Solar photovoltaic power generation is a kind of don't need fuel, pollution-free electricity for high and new technology. Make full use of solar light can not only save increasingly reduce non-renewable energy sources, and can reduce the pollution to the environment, which makes solar energy society be an important energy. Solar LED street light is a solar energy application examples in real life, so it is widely attention and research in recent years.This paper designs a kind of intelligent solar LED street light system. It is based on AT89S51 as the core, through the optical detection and battery power, to set function by microcomputer. In this paper, the concrete content includes solar power at home and abroad present situation and the working principle, scheme selection, component selection, system hardware, software design and the improvement direction of the system. The system's hardware design mainly includes the SCM smallest system, storage battery charging and discharging control circuit, main circuit and assistant circuit voltage conversion circuit, A/D conversion...
