毕 业 设 计（论文） 题 目：万年历事物报警系统研究与设计 摘 要 随着科技的快速发展，时间的流逝，至从观太阳、摆钟到现在电子钟，人类不断研究，不断创新纪录，电子万年历是一种应用非常广泛的日常计时工具，数字显示的日历时钟已经越来越流行，特别是适合在家庭居室、办公室、大厅、会议室、车站和广场等使用，也出现了各式各样的万年历其中壁挂式LED数码管显示的日历钟已逐渐受到人们的欢迎LED数字显示的日历钟显示清晰直观、走时准确、可以进行夜视等。并且在万年历上还可以增加很多其他功能比如温度显示、音乐报时等。而对于这样有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点，也符合电子仪器仪表的发展趋势，具有广阔的市场前景。 本课题首先对万年历的基本功能进行研究和分析，对万年历的系统进行设计，以及单片机芯片的选择。其次是显示模块的方案，LED液晶显示的强大功能。再者对报警系统加入的方案。实现万年历的功能的扩展。 关键词：万年历的市场需求；多样化的功能；报警系统扩展 CALENDAR THINGS ALARM SYSTEM RESEARCH ABSTRACT Along with the rapid development of technology, the passage of time, to the sun, pendulum clock from view until now, human continuous research, electric clock innovation record, electronic calendar is a very extensive daily timing tool, digital display calendar clock has more popular, especially suitable for family bedroom, office, hall, conference room, station and plaza use, also appeared a wide variety of calendar one wall hung LED digital pipe display calendar clock has gradually get the welcome of people LED digital display calendar clock shows clear intuitive, keep good time, can undertake night vision, etc. And in the calendar also can increase a lot of other functions such as temperature display, music chime, etc. For such a read convenient, direct display, functional diversity, simple circuit, low cost, and many other advantages, also accord with the development trend of electronic instruments, and has a broad market prospect. This subject is the basic function of calendar first study and analysis of the calendar, system design, and single-chip microcomputer chip choice. Second is the scheme, the LED display module the strong function of liquid crystal display (LCD). Furthermore to alarm system to join the scheme. Make calendar can realize alarm function. Keywords: Calendar market demand; The function of diversification; Alarm 目 录 第一章 绪 论 1 1.1万年历系统研究的背景 1 1.2功能要求 2 1.3主要的研究内容及模块的选择 2 1.3.1技术可行性 2 1.3.2单片机的选择 3 1.3.3显示模块的选择 4 1.3.4键盘模块的选择 4 1.3.5总体方案的选择 4 第二章 系统硬件电路的设计 6 2.
