基于单片机8031的太阳能交通警示牌的设计，以太阳能为能源, 给蓄电池加上充、放电保护装置, 防止过充电和过放电。该警示板设置在夜间有事故隐患的路段, 以太

阳能光伏板为传感器的光控电路, 控制LED 在白天关闭、夜间开启。-This design takes the solar energy as the energy, adds on the electric discharge protective device sufficiently to the accumulator

cell, prevents the surcharge and the electric discharge. This police shows the board to establish has the accident hidden danger road section in at

night, by photovoltaic board the sensor light controls the electric circuit, controls LED to close, at night, in the daytime to open
