基于光强的太阳能自动跟踪装置及其蓄电池充电优化控制

Solar Energy Automatic Tracking System based on Light Intensity and Its Charging for Storage Battery

设计了一种太阳能自动跟踪装置,此装置能够根据光的强弱自动转到光强最大的方向,从而提高太阳能利用率。所设计的自动跟踪装置主要由太阳能电池板蓄电电路、单片机主控电路、液晶显示电路和光敏采样电路四个模块构成,其中单片机主控电路是根据四个光敏电阻输出电压的差值,控制两舵机的转动使得太阳能电池板始终面朝光线最强的方向,并监控蓄电池和太阳能电池的状态,通过控制S8050三极管达到控制太阳能电池板向蓄电池浮充充电的目的,控制蓄电池的充放电,提高太阳能充电效率。

One set automatic solar tracking system which track the dimension of sun according to the light intensity was designed. The automatic tracking solar charging device mainly comprises of a solar panel storage circuit, MCU control circuit, liquid crystal display circuit and photosensitive sampling circuit of four modules. Depending on the difference output voltages of the four photosensitive resistor, the single chip microcomputer viz. the control circuit control the solar panels face the strongest light direction so as to charge the storage battery and solar battery. The transistor whose type is S8050 is to control the solar panel charging to the storage cell.
