基于菲涅尔透镜聚热器的太阳追踪系统设计

摘要

The sun's rays through the Fresnel lens refraction are gathered to the focal point , transforming the solar energy for heat energy to be used . To ensure that the focus of constant temperature and relatively fixed position , we designed a north-south direction oblique arrangement , east-west direction automatic tracking sun tracking system and design mainly include: mounting position and structure design , tracking sensing unit design , control circuit design and control strategy design and the sun tracking system can ensure the better for solar tracking of planar point focus Fresnel lens .%太阳光线经过聚焦菲涅尔透镜折射汇聚到焦点处，将太阳能转变为热能加以利用，为确保焦点温度恒定且位置相对固定，现设计了一种南北方向倾斜布置，东西方向自动追踪的太阳追踪系统，主要设计包括：支架安装位置及结构设计、追踪传感单元设计、控制电路设计和控制策略设计，该太阳追踪系统可保证平面点聚焦菲涅尔透镜能较好地进行太阳追踪。
