在太阳能发电中，太阳板受光面与太阳光线的角度是决定太阳能发电效率的关键因素。本设计的原理是利用传感器（光敏电阻）把接收到的光信号转换成电信号，然后经过信号处理及单片机控制后，由控制电路输出相应的控制数字信号驱动方位角调整机构和高度角调整机构实现相应的位置调整。(In solar power generation, the angle between the solar panel receiving surface and the solar light is the key factor to determine the efficiency of solar power generation. The principle of this design is to use sensors (photoresistors) to convert the received optical signals into electrical signals. After signal processing and single-chip control, the control circuit outputs corresponding digital signals to drive azimuth adjustment mechanism and altitude angle adjustment mechanism to achieve corresponding position adjustment.)
