摘要
通过对太阳运行轨迹理论的分析和研究,确定了太阳跟踪器的运动数学模型,并就其不同的天文算法公式进行了比较和选择,以保证系统的跟踪精度。在此基础上针对太阳跟踪器的控制原理,提出了系统的技术方案,详细阐述了控制系统的软件平台和硬件电路的设计。试验结果表明:两维程控太阳跟踪器的性能指标完全满足应用要求,运行稳定可靠,能适应各种复杂环境条件,这将在气象观测、高精度太阳跟踪测量以及太阳能源利用等领域有重要和广泛的应用。
The basic concepts of celestial geometry is analyzed,and the accurate model of the localization system is constructed.Different algorithms of solar localization are discussed and the best equation by minimizing errors is selected to obtain the astronomical position of the Sun.The design of control system is presented in detail according to the operational principle of solar-tracker, as well as the development of software and hardware. Experiments show that automatic solar-tracker is an all-weather, reliable, affordable tracking and accurate positioning facility for many applications such as weather observation, high-precision solar measurements, solar energy collector etc.
