摘　　要： 针对现有太阳光跟踪器难以实现360°快速精准跟踪问题,提出了球面受光原理的概念并籍此给出了一种新的太阳光跟踪策略。分析了平行太阳光线在检测球面的辐照强度分布,揭示了基于球面受光原理的新的太阳光跟踪机理;结合现有光敏材料物理特性给出了检测球面的构造方法,进一步利用给定区域内太阳光高度角变化范围、光敏材料灵敏性和太阳光跟踪精度要求给出了检测球半径的计算方法;进而构造了太阳光高度角和方位角跟踪数学模型。采用中国西北地区太阳光数据对模型进行仿真和实验验证,结果表明了所提出策略的精确性和正确性。 In light of the inability of existing solar trackers to achieve fast and accurate 360~ light-principle is proposed and a new sunlight tracking strategy based on the concept distribution of the paralleled sun＇s rays on the detection spherical surface is analyzed. A -tracking, the concept of spherical is given. The radiation intensity new sunlight tracking mechanism based on the spherical light-principle is revealed. According to the physical characteristics of existing photosensitive materials, the designing method of the detection spherical structure is given. Further, the calculating method of the detection sphere radius is given based on the change range of sunlight elevation angle in a given area, the sensitivity of photosensitive materials and the sunlight tracking accuracy requirement. A mathematical model for sunlight elevation angle and azimuth tracking is then developed. Finally, using the sunlight angle data in Northwest China for model validation, the accuracy and correctness of the tracking strategy proposed is clear as day.
