Sun position sensor

太阳位置传感器

Abstract

本实用新型公开了一种太阳位置传感器,包括寻找追踪单元和精确跟踪单元,其中,寻找追踪单元包括均匀分布的两组若干个光电二极管,各个光电二极管分别接受太阳光线的照射以产生电流,通过计算电流偏差值来初步确定太阳的位置,以引导精确跟踪单元转动,使太阳光线进入精确跟踪单元的探测范围。本实用新型结构紧凑,被控设备的跟踪精度可优于0.1度以上,适用于地球上可利用太阳能发电的任何地区使用。
The utility model discloses a sun position sensor, comprising a finding and tracing unit and an accurate tracing unit, wherein the finding and tracing unit comprises two groups of a plurality of photodiodes which are uniformly distributed; and each photodiode accepts irradiation of sun light to generate current, and the position of the sun can be initially determined by calculating a current deviation value to guide the accurate tracing unit to rotate, so that the sun light enters a probe range of the accurate tracing unit. The sun position sensor provided by the utility model has a compact structure. The tracing precision of equipment to be controlled can be superior to be more than 0.1 degree. The sun position sensor is applicable to any area capable of using solar energy to generate electricity power on the earth.
