  • 基于ATmega8的雙軸太陽跟蹤器設計

    為提高太陽能的利用率,以ATmega8單片機為控制核心,設計了一套光電跟蹤與視日運動軌跡跟蹤互補控制的雙軸太陽跟蹤器。該跟蹤器在晴天時,利用光敏電阻采集光強判斷太陽位置,控制步進電機實現光電跟蹤;在陰天時,采集時鐘器件PCF8583的時間信息,計算當前太陽位置來實現視日運動軌跡跟蹤。實驗表明:該太陽跟蹤器能在不同天氣狀況下對太陽進行較準確地跟蹤,能量接收效率提高了30%,達到充分利用太陽能的目的。 Abstract:  To improve the utilization rate of solar energy,a kind of solar tracking controller which effectively combined the sun angle tracking and photo electric tracking based on ATmega8is designed.In the sunny days,the solar tracking con-troller determines the sun's position by using photosensitive resistances to collect light intensity and control stepper motors to achieve photo electric tracking,n cloudy days,it collects clock chip PCF8583time information to calculate the current position of the sun and achieve the sun angle tracking.Experimental results show the solar tracking controller accurately tracks the sun in different weather conditions,improves received energy efficiency by30%and reaches the purpose of full use of solar energy.
