一種可攜式的固定焦距雙軸追日系統之設計

A Design of Portable Biaxial Solar Tracking System with Stable Focus

追日系統使得收集太陽能更有效率，提高能源轉換效率。本文說明一種將太陽反射光聚焦於固定區域之追日系統的設計製作。此追日系統以控制方位角和俯仰角方式來追蹤太陽在晨昏變換和季節變換的位置，並且以平衡環機構讓反射光可聚焦於固定區域，使得可以更方便於聚光和聚熱後的利用。系統整合Arduino微電腦架構的軟硬體為控制核心，光感測電路感測陽光方向，小型伺服馬達驅動延日機構，攜帶式電源為電力，設計使得太陽能應用可以成為攜帶式設備來運用。

A tracking system makes the collection of solar energy more efficient and improves efficiency of energy conversion. This article describes a design of a solar tracking system which allows the reflected sunli8ght focus on a certain region. The sun changes its position from morning to evening and from summer to winter. The design tracks the position of the sun via the azimuth and elevation angle control. The reflected light is focused to a fixed area by a gimbal mechanism. The accumulation of light and heat is more convenient than before. Arduino microcomputer hardware and software is the control center. Light sensing circuits result the direction of the sun. Small servo motors drive mechanism of the tracking system. A battery is as power. The design makes some applications with solar energy collection is a portable way.
