基于单片机的自动亮度路灯设计(含电路原理图,程序代码)(论文10000字,电路原理图,程序代码)
摘要
路灯作为公路基础设施极大的方便了人们夜间的出行,同时大量的路灯在方便了人们的同时也带来了巨大的能源消耗,因此对于路灯的节约使用,合理使用就非常有必要,这样可以极大的节约社会资源。
在本次课题基于单片机的自动亮度路灯设计中,围绕路灯的控制展开了设计,本系统采用了STC89C52单片机,按键,光照传感器,红外传感器,DS1302时钟模块,LCD液晶等构成整个控制系统的硬件基础,在功能上其具有手动和自动,定时三种工作模式;当自动亮度路灯进入自动模式时,其只要在光照不足并且红外检测到有人的情况下才会点亮路灯;在自动亮度路灯进入定时模式时,只会在设定的时间段内点亮路灯;在手动模式下,用户可以手动进行路灯的开关控制;具有显示设备,显示当前的时间,模式,路灯的状态信息等等;在设计的过程中,一方面针对课题完成电路图图纸设计,软件程序设计,另一方面还通过使用电烙铁,镊子等工具对自动亮度路灯的实物模型进行制作,通过焊接,硬件检查,程序下载,功能测试等步骤对目标功能进行反复调试,最终实现了课题目标。

As a highway infrastructure, street lamps greatly facilitate people's travel at night. At the same time, a large number of street lamps not only facilitate people, but also bring huge energy consumption. Therefore, it is very necessary for the economical and rational use of street lamps, which can greatly save social resources.
In the design of automatic brightness street lamp based on single chip microcomputer, the design is carried out around the control of street lamp. The system adopts STC89C52 single chip microcomputer, key, light sensor, infrared sensor, DS1302 clock module and LCD liquid crystal to form the hardware foundation of the whole control system. In terms of function, it has three working modes: manual, automatic and timing; When the automatic brightness street lamp enters the automatic mode, it will light up the street lamp only when the illumination is insufficient and the infrared detects someone; When the automatic brightness street lamp enters the timing mode, it will only light up the street lamp within the set time period; In the manual mode, the user can manually control the switch of street lamps; It has a display device to display the current time, mode, status information of street lamps, etc; In the process of design, on the one hand, the circuit diagram, drawing design and software program design are completed for the subject. On the other hand, the physical model of automatic brightness street lamp is made by using electric soldering iron, tweezers and other tools. The target function is debugged repeatedly through welding, hardware inspection, program download, function test and other steps, and finally the goal of the subject is realized.
