|
摘要
使用几何光学分析法对槽式聚光系统的太阳入射光与聚光器法线夹角最大允许值进了讨论,并给出了最大值的计算公式;讨论了遮光法追光传感模块的工作原理,推导出了遮光板高度的计算公式;通过电路设计把光敏电阻阻值转换成电压信号,经过AD转换后,使用单片机进行数据处理;讨论了的东西光敏电阻转换后的ADC值与判决阈值ADC_th对比产生的4种不同结果与太阳位置的判断方法,并编写单片机程序实现了该算法;经测试表明,制作的追光模块能够控制槽式聚光系统正确追光。
The maximum allowable angle between the incident light and the normal line of the parabolic in the trough solar collector is discussed by using the method of geometrical optics.And the calculating formula for the angle is also given.The principle of shading method sun tracking sensing module is discussed.Then a formula is derived to calculate the height of the shading plate.The method of judging the four different relative positions of the sun and parabolic trough solar collector by comparing the ADC value of east and west between ADC_th is discussed.A sun tracking hardware module sample is designed.According to the test result,the module can drive the parabolic trough solar collector system to track the sun correctly.
