摘　　要：为了更好地利用和推广"太阳能"这种绿色清洁能源,设计了太阳能路灯智能控制系统。详细描述了其硬件组成、软件设计及测试过程。首先利用光敏电阻实现太阳能板对太阳光的实时跟踪,保证阴雨天在短时间日照下充满蓄电池;其次使用了光控和时控结合的方法,避免了光控方法易受干扰、时控方法需频繁改变时间设置的麻烦;为了达到节电目的,在深夜行人较少时路灯根据设置的熄灯时间自动熄灭,早上行人多时根据设置的开灯时间亮灯。最后设计过充过放保护策略提高蓄电池使用寿命。实际测试证明该系统太阳光自动跟踪误差在2度以内,蓄电池充放电压严格控制在设定范围以内,具有一定的参考和推广价值。In order to better use and promote solar as a kind of green clean energy, in this paper a solar street light intelligent control system was designed, describing its hardware components, software and test process in detail. At first, in order to guarantee the full charge of battery in a short time in rainy days, the photosensitive resistor was used to realize the real time track of sunlight. Secondly, the light control and time control were used together to avoid the susceptibility of light control method to interference and the frequent time sets of the time control method. To save energy, the light was turned off according to the time setting, when there were few passersby in deep night, and turned on in early morning when there were more passersby. Finally, the overcharge and overdischarge protection strategies was designed to improve battery life. The actual tests prove that the error of automatic sun tracking is within 2 degrees, and the battery charge and discharge voltage is controlled strictly within the range setting. The system has some reference and promotion value.
