摘要
介绍了一种智能路灯控制系统的设计:以AT89S52单片机为中心控制器,由按键调整、时钟、检测和液晶显示等电路模块组成。系统利用光敏电阻和AD转换器检测环境的明暗程度,采用红外检测有无人或物体经过从而实现路灯的自动控制。系统将实时时间和灯的设定时间、灯的故障信息用液晶显示出来,出现故障的同时进行声光报警。
This paper introduces an intelligent street lamp-control system design：MCU AT89S52 is its core controller,and it consists of the blocks of keyboard input,clock,testing and LCD displaying.The system makes use of photoresistor and A/D to test the brightness of environment,the passage of people is checked by infrared testing so as to achieve the automatic control of lamps.The real time,the set time and the error message are displayed on LCD.It also alarms by the way of light and sound when some lamps fails.
