摘要
系统本着充分利用太阳能供电,并且实现路灯照明系统的智能化为目的,以AT89S51单片机为控制核心,自行设计了一套太阳能LED路灯智能照明系统。在该系统中以单片机与模数转换器构成数据采样模块,实现蓄电池的过充与过放保护电路;数码管显示电路显示蓄电池的电压和当前时间;通过光敏电阻感知外界环境亮度,实现LED路灯的开启与关闭;无线模块实现对LED路灯人为的控制。实验结果表明该系统性能稳定、实时性高、节能、智能,具有良好的应用前景。
The Solar LED intelligent lighting system makes full use of the solar power supply for the purpose of the intelligent lighting with AT89S51 MCU as the control core.In the system the data sampling module composed by MCU and the analog-to-digital converter,to realize the battery overcharge and over discharge protection circuit.Digital tube display circuit displays the battery voltage and current time.Through photosensitive resistance to perceive the external environment brightness,to realize the opening and the closing of the LED street lamp.Wireless module to realize the LED street lamp artificial control.The experimental results show that the system has stable performance,high real-time performance,energy-saving,intelligent,and has good application prospect.
