A New Scheme of Sunshine Recorder with Integral Sphere Principle

摘要: 该文提出了一种利用积分球原理设计的新型日照传感器。该传感器由限角挡环、积分球体和光电探测器组成。积分球为一有5个针孔的空心正球体。针孔可阻挡散射光进入球内，而射入球内的直射光，经内壁多次漫反射后，其亮度呈均匀分布。与日照阈值下相应的亮度相比较可确定日照之有无。该日照传感器具有无转动部件、结构简单、无需调整及便于操作等优点。

Abstract: A new scheme of sunshine recorder with integral sphere principle is put forward. The recorder consists of ring with diaphragms, integral sphere and photoelectric receptor. The integral sphere is a hollow regular sphere with five pores of needle. The pore of needle can resist scattered light throwing into the sphere, and direct solar radiation thrown into sphere is diffusely reflected through the internal wall for many tines, and then homogeneous distribution of the irradiance is formed. By means of comparing with the irradiance of sunshine threshold, there is sunshine or not to be determined. The sunshine recorder has some advantages, such as nonrotating parts, simple structure, unnecessary adjusting and easy operating
