摘　　要：结合蓄电池的充电方法和特性,设计了基于ATmega 48单片机为核心的太阳能路灯照明系统,包括太阳能电池、蓄电池、充电电路、驱动电路和指示电路等,通过单片机软件算法编程科学地控制功率开关管的导通与关断,对蓄电池的充放电和路灯加以控制,科学地采用不同百分比的PWM对蓄电池进行充电,依据不同的需求选择不同工作模式进行供电照明。Based on the charging method and property of battery,solar street lighting system,including solar cell,battery,charging circuit,driver circuit,indicating circuit and so on,is designed based on the core of ATmega 48 single chip machine. By using single chip machine software algorithm programming to scientifically control the switching on and the switching off of power switch tube,the charging and discharging of the battery and street lighting are controlled,the battery is charged by scientifically using PWM with different percentage,and power supply for illumination is operated by choosing different working modes according to different demands.
