基于单片机的电子时钟控制系统字数:7935,页数:42 论文编号:JD340 摘 要介绍了多功能数字钟的系统设计。系统具有时间设置及显示、闹钟等功能。本系统采用时钟芯片DS12C887和单片机AT89C51作为核心，通过外部键盘来实现对时钟芯片内部寄存器的修改，而完成对时钟数据的修改、闹钟时间的设定和铃声的编辑。有关的数据通过LCD来显示。系统带有液晶显示器，配合按键提供友好的用户界面，操作简单。该数字钟能长期、连续、可靠、稳定的工作；同时还具有体积小、功耗低等特点，便于携带，使用方便。单片机软件编程主要实现键盘、液晶显示。关键词：单片机,时钟芯片,键盘,LCDAbstractThis paper describes the design of a multi-functiond digital clock as displaying and setting time for clock and alarm .It is the system center that the real time clock DS12C887 and AT89C51. User can use the keyboard to modify the data that indicate the time data which include the daytime, alarm, date, etc. The data can be show by the LCD. It can be programmed the ringer which you like., this system has other special features such as temperature measurement and data protection at power faillure. The system takes liquid crystal display, matching with a key to provide amity of customer interface, the operation is simple, having the temperature examination function in the meantime, the clock data and the temperature data .consecution,credibility,stable work;Still have a physical volume in the meantime small,the power consume a low etc. characteristics, easy to take, the usage system software design includes a single slice a plait distance with two parts of machine calculator software plait distance mainly carries out a parameter constitution,string to go a people's data to receive,the instruction send out and data of manifestation with saving..Singlelicethemachinesoftwareplaitdistance,LCDmanifestation,temperature examination each mold of etc. piece.

Single-chip microcontroller that micro-computer (Single-Chip Microcomputer) gathering CPU, RAM, ROM, the timing, number and variety of interface integrated microcontrollers. Widely used in various fields. In this paper, the music alarm clock designed by AT89S53 SCM control. The music alarm clock from SCM system is the smallest system and the expansion of LED display circuit and voice circuit. Using single-chip C programming language, can be set to achieve a number of alarm clocks, alarm clocks on time to play music, and showing the date and other functions. This paper introduces the music alarm clock software and hardware design, and design, debugging process of the problems encountered and solutions. The topics designed music alarm system is simple, cost, low-cost, multifunctional, with a very strong sense of practicality. Keywords : music, simple arrangements, clock timing 题目:SCM Application Development-music electronic clock design 希望对您有所帮助，祝您成功！
