【正文】 r to track to achieve the level direction. At the same time, another small gear is rotated by another stepper motor according to the control the large gear and the solar panels are rotated by the small gear in order to track to achieve the vertical direction. Solar is tracked by the two stepper motors together. Second, control system part is designed. Control system mainly includes the sensors part, stepper motor, MCU system and the corresponding external circuit, and so on. Photoelectric detection system is used to track solar. Sensors use photosensitive resistance. The two same photosensitive resistances were placed in east and west direction of the bottom edge .When the two photosensitive resistances received different light at the same time, the signal from parison circuit is sent to MCU in order to rotate stepping motors. Keywords ： Solar energy Tracking Photosensitive resistance SCM Stepping motor 畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 第 1 頁(yè) 目錄 1 緒論 .............................................................................................................................................. 1 課題來(lái)源 ................................................................................................................................ 1 課題背景 ................................................................................................................................ 1 能源現(xiàn)狀及發(fā)展 .............................................................................................................. 1 我國(guó)太陽(yáng)能資源 .............................................................................................................. 1 目前太陽(yáng)能的開(kāi)發(fā)和利用 .............................................................................................. 1 太陽(yáng)能的特點(diǎn) .................................................................................................................. 1 課題研究的目的 ................................................................................................................. 2 研究課題的意義 .................................................................................................................... 2 新環(huán)保能源 ...................................................................................................................... 2 提高太陽(yáng)能的利用率 ...................................................................................................... 3 太陽(yáng)能利用的國(guó)內(nèi)外發(fā)展現(xiàn)狀 ............................................................................................ 3 太陽(yáng)追蹤系統(tǒng)的國(guó)內(nèi)外研究現(xiàn)狀 ........................................................................................ 4 論文的研究?jī)?nèi)容 .................................................................................................................... 5 論文結(jié)構(gòu) ................................................................................................................................ 5 2 太陽(yáng)能自動(dòng)跟蹤系統(tǒng)總體設(shè)計(jì) .................................................................................................. 6 本課題的機(jī)械設(shè)計(jì)方案 ....................................................................................................... 6 跟蹤方案的比較選擇 ............................................................................................................ 7 本設(shè)計(jì)的跟蹤方案 .......................................................................................................... 7 3 機(jī)械設(shè)計(jì)部分 .............................................................................................................................. 8 太陽(yáng)能自 動(dòng)跟蹤系統(tǒng)機(jī)械設(shè)計(jì)方案 .................................................................................... 8 電池板的選擇及布局分析 ....
