摘要

近年來能源危機及開發新興能源議題已刻不容緩，其中被視為綠色能源之首的太陽能更受矚目，該能源具有取之不盡、用之不竭及成本低之優勢，在替代能源上極具競爭力；唯任何使用在太陽能的設備，均需有追日之功能，才能達到最佳的能源轉換效率。故本研究之目的在開發一組碟盤聚焦型高精密度主動式雙軸追日系統，並以實驗探討追日特性，其內容涵蓋（１）追日機構、（２）追日控制ＰＸＣ模組、（３）附有迴授機構之驅動器及（４）ＰＰＣＬ軟體編寫太陽軌跡理論程式；全系統經過實驗測試及ＥＸＣＥＬ算式表交叉核對結果顯示:（１）程式軟體計算之數據與ＥＸＣＥＬ算式表之數據相符；（２）手動模擬驅動機構運作確實能夠朝向太陽，達到最大之集光效率；（３）附有迴授機構之驅動器，可彌補軟體程式計算誤差所導致追日角度之偏差。

In recent years, the energy crisis and the development of new energy issues is urgent, which is considered the first solar green energy while in the spotlight, with their inexhaustible and the advantages of low cost, highly competitive in alternative energy force, only any use of the solar energy equipment, are required to have at the functional recovery, to achieve the best energy conversion efficiency. Therefore, this study aims to develop a set of disc-type high-precision active focus axis tracking system, and experimental research tracker feature, which covers (1) sun tracking system agencies, (2) tracker control PXC Modular , (3) with a feedback mechanism with the drive module and (4) PPCL sun tracks theoretical preparation software programs; whole system through experimental testing and EXCEL formula sheet cross-checking results showed that: (1) calculation of the data and the software program EXCEL formula sheet data consistent; (2) manual operation of the analog drive mechanism can indeed toward the sun, the light collection efficiency reaches the maximum; (3) drives attached feedback mechanism can compensate for the software program calculation errors resulting tracker angle deviation.
