详细地，本实施例中所述环境照度大于第二照度阈值，即为外界光较强或光线明亮，光伏电池板能够将光转换为电能，所述电能能够满足电源控制电路及外围电路的使用，并有一定的剩余，从而将剩余的电能存储在储能电池中。而当环境照度小于第三照度阈值时，即为外界光较弱或光线较暗，光伏电池板将光转换的电能较少，所述电能不足以支撑电源控制电路及外围电路的使用，此时，可以采用储能电池中存储的电能通过所述电源控制电路对外放电，从而对外供电。因此，本实施例中的第二照度阈值大于第三照度阈值。
在本发明的其他实施例中，还可以通过判断环境光的强度或者亮度判断是否对储能电池进行充电，或需要储能电池进行放电，本实施例中对此 不做限定，只要光伏电池板转换的电能充足，则对储能电池进行充电，若不足，则需要储能电池对外放电。
所述语音模块包括：语音芯片和喇叭；所述语音芯片预设有盲道多种使用状态的提醒信息，所述语音芯片的输入端作为所述语音模块的输入端，所述语音芯片的输出端与所述喇叭的输入端相连。在所述盲道上有障碍物或行人时，所述语音芯片根据所述微处理器的第一输出端的信号驱动所述喇叭播报所述提醒信息。
可见，本发明提供一种太阳能盲道提醒系统，通过对盲道的障碍物或行人进行检测，并播报提醒信息，同时通过光伏供电模块将太阳能转化电能以对各组件进行供电。以解决现有盲道仅靠自身凹凸设计结构来提醒盲人，无法给盲人准确引导和认知前方路况的问题，能提高盲道的智能性，改善盲人出行的便利性。
本发明还提供一种盲道，设置有如上所述的太阳能盲道提醒系统。
如图2所示，所述光伏供电模块1设置在行进盲道凸起结构上、行进盲道相邻两个凸起结构之间或提示盲道上的凹陷结构内上，所述语音模块2设置于盲道磁砖的边角处。所述检测模块3可与光伏供电模块1集成在一起，也可以分开设置在盲道边角或凸起上。常将光伏供电模块排列成矩阵形状或竖排方式，LED发光模块4常设置在盲道凹陷处。
具体的，本实施例中优选地，光伏供电模块1设置在行进盲道相邻两个凸起结构之间的凹陷位置或者设置在提示盲道上的凹陷结构内，行进盲道或者提示盲道上的凸起结构能够对位于凹陷位置的光伏供电模块进行保护，避免踩踏过程中，对光伏供电模块中的光伏电池板造成损伤，降低光伏电池板的光电转换效率。
在本发明的其他实施例中，光伏懂点模块1还可以设置在行进盲道的凸起结构上，沿着行进盲道的凸起结构设置光伏电池板，为避免长期被踩踏，造成光伏电池板上出现损伤或者板材上出现划痕，降低光伏电池板的 光电转换效率，可选的，当光伏供电模块1设置在行进盲道的凸起结构上时，还可以在光伏供电模块1上方设置玻璃板，对光伏供电模块1进行保护，本实施例中不限定所述玻璃板的具体材质，可选的，所述玻璃板可以是有机玻璃板或者钢化玻璃板。
