摘 要 路灯照明对人们的日常生活有着很重要的作用，路灯照明系统的好坏直接影响到人们夜晚出行的安全。中国的路灯控制系统老旧，效率低，浪费能源过多。路灯系统控制方式落后，无法远程控制开关灯时间，缺乏设备故障检测和报警系统。急需升级改善。单片机拥有卓越的控制能力，已经广泛应用在很多领域。基于单片机的智能路灯控制系统可以改变中国路灯现状，使得路灯的管理变得简单、可靠，能节约更多的电能，能使人们更加安全的出行，减少因路灯控制系统不完善而引起的交通事故。因此，设计一款智能路灯控制系统具有非常重要的意义。 文章介绍了模拟路灯控制系统的两大组成部分，即硬件系统和软件系统。硬件系统以AT89S52单片机为主控芯片，由实时时钟芯片DS1302产生实时系统时间，由LCD1602液晶显示屏显示菜单、提示和实时时间等信息，使用独立式键盘调整切换功能菜单、设置开关灯时间等，采用光敏电阻检测环境的明暗情况，使用反射型红外光电传感器检测交通情况，配合蜂鸣器和LED灯实现故障报警。软件系统包含系统监控程序模块、显示程序模块、键盘程序模块、实时时钟程序模块，环境检测程序模块、报警程序模块、交通检测程序模块，设定路灯开关时间程序模块等。 通过在proteus软件中模拟仿真调试，实现了课题规定的功能和性能指标要求，设计成果具有一定的推广应用价值。 关键词 ： 路灯控制；AT89S52；DS1302；LCD1602 ABSTRACT Street lighting has a quite significant impact on peoples daily life, the quality of the street lamp lighting system directly affects the safety of people at night. In china， street lamp control system is old-style, low efficiency and waste too much energy.The mode of streetlight control system is backward, it can’t remotely control switch lights in time, and lack equipment in fault detection and alarm system, which is badly in need of upgrading. MCU has excellent control ability, which has been widely used in many fields. Based on MCU intelligent lighting control system can change the status of Chinese street lighting, the street lamp management becomes simple and reliable, which can save more energy, make people more safe travel and reduce traffic accidents caused by defective street lamp control system . Therefore, it is great crucial to design a intelligent street lamp control system. This paper introduces the two components of the analog street lamp control system, namely the hardware system and the software system. The main control chip of hardware system is the AT89S52 microcontroller , real-time system time is produced by the real-time clock chip DS1302 , the information of menu,prompt and real time is displayed on the LCD1602 , hardware system use a separate keyboard to adjust or switch function menu and set the time switch lights, photosensitive re
