XXX 学院毕 业 论 文课题名称: 基于单片机的万年历设计 作 者: XXX 学 号: XXX 系 别:___ 电子工程系 专 业:__ 电子信息工程技术 _ 指导老师:_______ XXX XX 年 XX 月 XX 日摘 要本设计以单片机芯片 STC89C52 为中心,通过外挂接 DS12C887 作为时钟芯片,为系统实时的更新时间、日历等。DS18B20 作为温度传感器芯片,用于实时采集当前所处的环境温度。1602 液晶作为实时显示器件,显示单片机采集的所有数据。当在公共场所时,为了方便调节时间,外加红外遥控和键盘两种方式调时功能。于此,构成了一个实时时钟万年历系统。最后,通过软件对其原理图进行绘制和程序的编写,并且调试运行。关键词:单片机芯片 STC89C52;DS12C887 芯片;DS18B20 温度传感器;LCD1602液晶;红外遥控AbstractThe design on the single chip computer chip STC89C52 as the center, through the plugin meet DS12C887 as the clock chip, real-time updates for the system time, calendar, etc. As the temperature sensor DS18B20 chip to the real-time data acquisition at this temperature environment. 1602 LCD as real-time display device, shows all of the data collection single chip microcomputer. When in a public place, in order to facilitate the regulating time, plus infrared remote control and keyboard two ways when the function. In this, and form a real time clock calendar system. Finally, through the software to its principle chart draw and the writing of the program, and debug operation.Keywords: single chip microcomputer chip STC89C52; DS12C887 chip ;DS18B20 temperature sensor; LCD1602 liquid crystal ;infrared remote control目 录 1 引言11.1 课题的来源和意义....................................................................................................11.2 系统总体方案介绍....................................................................................................22 方案论证22.1 时钟芯片的选择22.2 显示器件的选择43 单元电路设计43.1 DS12C887 时钟电路设计43.1.1 DS12C...
