At the same time, the investment and construction of large photovoltaic power stations all over the world also provide a new energy solution for human beings.. In addition, small off grid system because it has the characteristics of simple and flexible, it in the future will bee another important field of photovoltaic power generation has a pivotal. Therefore, the study of off grid solar charging and discharging system is very necessary. In view of this, this paper designs the charging and discharging control of the solar energy acid battery based on SCM, and adopts the STC89C52, the battery is used for the leadacid battery.. The main work of this paper is the research of PV array power and PV array bined with theory of leadacid battery charging and discharging, thus making the battery safety and reasonable charge and discharge, so that the load can work stably and reliably. Keywords: single chip microputer UC3906, STC89C52, lead acid battery, battery charge and discharge control system. 中北大學(xué) 2021 屆畢業(yè)設(shè)計(jì)說明書 1 目錄 1 引言 ............................................................................................................................................. 1 課題研究背景及意義 . ............................................................................................................. 1 光伏發(fā)電的發(fā)展歷程與發(fā)展現(xiàn)狀 ........................................................................................... 3 本論文研究的主要內(nèi)容 .......................................................................................................... 4 2 系統(tǒng)設(shè)計(jì)簡介 ............................................................................................................................. 5 單片機(jī)的簡介及選擇 ............................................................................................................ 5 路燈系統(tǒng)簡介 ........................................................................................................................... 7 3 系統(tǒng)硬件電路設(shè)計(jì) ..................................................................................................................... 9 PV 板特性與等效電路 ............................................................................................................. 9 太陽能 LED 路燈控制器功能模塊概述 ............................................................................... 13 晶振電路 .............................................................................................................................. 13 復(fù)位電路 ........................................................................................................................... 13 電壓采集模塊 ...................................................................................................................... 14 LCD1602
