基于单片机控制的智能书桌.doc

摘要 书桌已经成为日用品，是人们居住环境中不可缺失的一部分。而随着时代的发展，尤其是电子信息时代的发展，以前的书桌仅仅用来写字的功能已经不能满足当代人们的需要，人们希望在书桌上集合更多的功能，使它作为一个更加智能，更加方便易用的产品。而与此同时，单片机技术已经伸入到各个领域，基于单片机的产品已经有了越来越广泛的市场，因此，设计一款基于单片机的智能书桌也就被提上了日程。 本文介绍了一种基于STC89C52单片机的智能书桌，主要是以单片机为核心，将台灯、日历与闹钟功能集成在书桌上，经过不同的方案对比，最终确定出以单片机STC89C52为核心，LCD1602屏作为显示模块，显示日历，当前时间与闹钟的信息，采用普通按键可以对日历，时间与闹钟时间进行调节，利用人体红外模块开作为传感器，将信号输入到单片机中，进行一系列处理后控制台灯的开关，经过软件模拟与硬件的调试，证明了电路设计正确，原理可行，达到了预期毕业设计的目的。 关键词：智能书桌，STC89C52单片机，台灯，日历 Abstract? The desk has become a commodity, is an indispensable part of peoples living environment. With the development of times, especially the development of electronic information age, before the desk just to write function has been unable to meet the needs of contemporary people, people want to set more functions on the desk, and make it as a more intelligent, more convenient and easy to use products. At the same time, microcontroller technology has been extended to various fields, MCU based products have been more and more widely in the market, therefore, the design of a microcontroller based intelligent desk will be put on the agenda. This paper introduces an intelligent desk based on STC89C52 single chip, is mainly based on the single chip microcomputer as the core, the lamp, calendar and clock function integrated in the desk, through different scheme comparison, determined the MCU STC89C52 as the core, the LCD1602 screen as the display module, display the calendar, the current time and alarm information, use ordinary button can be on the calendar, time and alarm time adjusted, using the human body infrared sensor module as input signal, to a single chip, switch control lamp through a series of treatment, the debugging software simulation and hardware circuit design, proved correct, feasible principle, to achieve the expected purpose of graduation design.
