摘 要:設計了一種基于單片機的太陽能自動跟蹤器,該跟蹤器由單片機STC89C52作為微控制器發送脈沖給步進電機驅動器,在天晴時采用普通的硅光電池作粗略跟蹤,位置傳感器PSD作精確跟蹤,天氣情況不好時則采用天晴時追蹤記錄的數據進行跟蹤。實際測量數據表明,該自動跟蹤器可有效提高系統接收的太陽輻射量,達到了預期目的。

Abstract: This paper designed a solar automatic tracking controller based on single chip. The tracking controller took the single chip STC89C52 as the microcontroller to send pulses to a step motor driver. In sunny days, an ordinary silicon photocell was used for rough tracking and a PSD sensor was used for accurate tracking. When the weather condition was not good, data recorded in sunny days was used to carry out tracking. Actually measured data shows that automatic tracking controller can effectively raise the system to receive solar radiation energy, reaching preset goal.
Key words: automatic tracking; solar energy; single chip; step motor; position transducer
