摘要
针对以往太阳方位手动计算复杂易错且不具备实时性的缺点设计了一套实时跟踪系统。该系统采用微芯公司生产的dsPIC作为核心处理器,具有处理速度快、功耗低的优点。系统结合了HMC3200电子罗盘与高精度视频方位仪,能够实时获取装置的位置指向和实时图像加以观察,使用的太阳方位算法简洁可操作性强、精度高,运行结果显示能满足实时追踪的效果。
The traditional method of manual calculations of solar tracking is complex and error-prone, so that it cannot be used for tracking the sun in real time. In this paper we give a design of a real-time solar tracking system to avoid the traditional method. The system uses a dsPIC as the key processor, which has the advantages of relatively high processing speed and low power consumption. The system incorporates an HMC3200 eleetromic compass and a high-precision video instrument to measure azimuth. It can record pointings of the instrument and video images along these pointings in real time. The new solar azimuth algorithm used in the system is simple and easily operable. Results of test runs show the the system can meet the requirement of real-time solar tracking.
