南京信息职业技术学院 毕业设计论文 作者 薛 学号 0722T32 系部 电子信息学院 专业 无线电技术 题目 基于单片机的家用电远程遥控装置 的设计与制作 指导教师 李 评阅教师 完成时间： 2010年 月 11日 毕业设计(论文)中文摘要 题目： 基于单片机的家用电远程遥控装置的设计与制作 摘要：随着电子、计算机科学的发展，我们的生活和工作中都会接触很多的电子产品，而这些电子产品大多都是被称作单片机的微型计算机所控制，本文主要介绍以单片机AT89C51为核心，充分利用单片机的片内外资源，配合使用双音多频接收器MT8870实现远程电话遥控家电开关等功能的仪器。设计中使用了EEROMX25045来存储密码；采用语音芯片实现操作步骤提示、操作成功反馈提示等功能，操作简单、可靠；为了不额外占用资源，在软件中设计有一段时间内无人操作自动挂机的功能；在设计时为了解决单片机I/O口资源有限的问题，我们选用了CPLD可编程逻辑器件来扩展单片机的I/O口，从而实现电路的逻辑功能。 本次设计基于完备的软硬件系统，很好的实现了自动摘机、语音提示、密码核对、操作提示、状态显示及超时自动挂机等功能。 关键词：AT89C51 MT8870 EEROM 单片机 CPLD 毕业设计(论文)外文摘要 Title : Based on the SCM home electrical equipment remote control device design and production of Abstract: With the electronics, Such as electronics, computer science development, we will be living and working in contact with a lot of electronic products, electronic products which are mostly known as a micro-computer controlled by the microcontroller, this article focuses on the single-chip microcomputer AT89C51 the core, make full use of on-chip microcontroller internal and external resources to support the use of dual-tone multi-frequency receiver MT8870 remote telephone switch features such as remote control home appliances instruments. Used in the design of EEROMX25045 to store passwords; use of voice-chip steps suggest that the successful operation of features such as feedback tips, simple operation, reliable; in order not to occupy the additional resources in the design of software for some time to hang up the unmanned automatic function; in the design in order to solve the MCU I / O port resources are limited, we use a CPLD programmable logic device to expand the MCU I / O port, in order to achieve circuit logic functions. The design is based on a complete hardware and softw
