基于单片机控制的太阳自动跟踪系统设计

Design of Auto Sun Tracking System Based on Single Chip Computer

运用欧几里得几何知识,分析研究了太阳自动跟踪系统的旋转原理,据此设计了太阳自动跟踪系统的机械结构和以单片机为控制核心的自动跟踪控制器。重点介绍了实现对太阳最强光实时跟踪的光检测电路与电机驱动电路的设计。实验表明所设计的系统中太阳能电池板可高精度自动跟踪太阳,太阳能发电系统的效率较高。

The rotating principle of auto sun tracking sysytem is analyzed by using Euclidean geometry knowledge. Mechanical structure and controller based on SCM（ Single chip microcomputer） of auto sun tracking system is designed. Optical detection circuit and motor drive circuit, which can realize the real time tracking to the sun , are introduced mainly. Experimental result shows that the system can make the solar panels follow the sun accurately . The ettqcieney of solar power generation system are improved.
