控制器的(de)主要(yao)功能(neng):控制器主要(yao)實(shi)(shi)現(xian)以下(xia)功能(neng)：蓄電(dian)(dian)池(chi)和(he)太陽電(dian)(dian)池(chi)的(de)電(dian)(dian)壓采樣(yang)。通過電(dian)(dian)壓采樣(yang)電(dian)(dian)路(lu)實(shi)(shi)現(xian)對蓄電(dian)(dian)池(chi)和(he)太陽電(dian)(dian)池(chi)的(de)適時(shi)電(dian)(dian)壓采集及A/D轉換。

　　蓄電池(chi)的(de)充放(fang)電控制(zhi)。單片機(ji)將采樣電壓(ya)與設定(ding)電壓(ya)比較，根據比較的(de)結果(guo)發出(chu)相應(ying)的(de)控制(zhi)信號，實現蓄電池(chi)的(de)充放(fang)電控制(zhi)。

　　蓄電池供電(dian)(dian)(dian)與市電(dian)(dian)(dian)供電(dian)(dian)(dian)的自動切(qie)換(huan)控制。將(jiang)采(cai)集到的蓄電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓Vcx和蓄電(dian)(dian)(dian)池(chi)的放電(dian)(dian)(dian)保護電(dian)(dian)(dian)壓VoXmn比較(jiao)，單片機相應端口向(xiang)蓄電(dian)(dian)(dian)池(chi)供電(dian)(dian)(dian)一市電(dian)(dian)(dian)供電(dian)(dian)(dian)切(qie)換(huan)電(dian)(dian)(dian)路發(fa)出(chu)控制信(xin)號，實現對(dui)蓄電(dian)(dian)(dian)池(chi)供電(dian)(dian)(dian)一市電(dian)(dian)(dian)供電(dian)(dian)(dian)切(qie)換(huan)的自動控制。
