摘要

针对塔式太阳能发电系统多定日镜跟踪太阳的问题

提出了一种基于信号处理芯片(DSP)的两轴日光方位传感器。传感器由DSP、四象限光电池、高度角调节电机、方位角调节电机和编码器等构成

控制软件包括模拟量的采集程序、电机控制程序、光电编码器的读数程序等。传感器根据四象限光电池的电压信号调节高度角电机和方位角电机

使光线与四象限光电池垂直

读取编码器的数据进行变换即可得到太阳的实时位置信息。设计的日光方位传感器结构简单、成本低廉

适用于多种受光器件的群控跟踪系统。

Abstract

Directing against the problem of using many heliostats for solar tracking in the tower type solar energy power generation system

a kind of biaxial solar orientation sensor based on digital signal processor(DSP) has been put forward.The said sensor is consisted of DSP

four-quadrant photocell

electric motor for regulating the altitude

electric motor for regulating the azimuth

and encoders etc..The control software includes the analog acquisition programm

electric motor control programm

and serial communication interface programm.The sensor regulates the electric motors according to the voltage from four-quadrant photocell to keep the said photocell vertical to the sunlight

and then the sun's real time position can be known by reading and converting the data of encoders.The designed solar orientation sensor feature

simple structure and low cost

which can be used in group control system with many photic devices.
