摘要
随着时代的进步,科学技术的发展,单片机已经渗透到我们生活中的各个角落。伴随着人们生活水平的提高,人们对日常生活用品的功能和集成度的要求也越来越高,并且人们的低碳环保理念也越来越强。台灯是我们生活中的必需品,使用非常广泛,对此设计了多功能台灯。
该设计以51系列单片机AT89S52为控制核心,来实现集多种功能于一体的电子台灯,设计系统时采用模块化的设计方法,分别设计了各个功能的单元模块,系统的硬件部分主要包括八大部分。单片机最小系统选用AT89S52单片机;温度传感器电路主要由数字芯片DS18B20来完成;显示模块用LCD1602A来显示温度、时间和日期等内容;按键模块用来调整时间、日期,电位器来调整LED的亮度;闹钟模块选用时钟芯片DS1302完成,来产生时间和日期,当液晶显示的当前时间和闹钟设定的时间一致时,用蜂鸣器来报警。系统的软件部分用单片机C语言来编程,实现了该设计全部控制功能。该多功能台灯可以显示当前温度、时间和日期、调节灯泡的照明强度、可以设置闹钟时间、具有闹钟报警功能。整个系统结构清晰明了,功能齐全,操作简单,具有很强的实用价值。

Abstract
With the progress of the times, the development of science and technology, SCM has been infiltrated into our lives in every corner. With the improvement of people's living standard, people on the daily necessities, function and integration requirements are also getting higher and higher, and people of low carbon environmental protection concept is also getting stronger and stronger. The lamp is necessary in our life, is widely used, this design of the multifunctional desk lamp.
The design of 51 series single-chip puter AT89S52 as the control core, to realize the integration of multiple functions of electronic lamps, the design of the system uses a modular design method, respectively, design of each function module, system hardware consists of eight parts. The smallest single-chip system selects AT89S52microcontroller; temperature sensor circuit is posed of a digital chip DS18B20 plete; display module using LCD1602A to display the temperature, time and date content; key module is used to adjust the time, date, a potentiometer to adjust the brightness of LED; alarm module selects the clock chip pleted, to generate a time and date, when the liquid crystal display the current time and alarm set time, buzzer alarm. The software of system MCU C language programming, realize the design of all control function. The multifunctional desk lamp can display the current temperature, time and date, adjust the bulb li
