1、数字电子时钟设计报告1250数字电子时钟语音播报系统设计报告 学 院：电子工程学院班 级：2010电子信息工程1班姓 名：覃阳青学 号：201012701250指导老师：蒋 品 群时 间：2013-4-20数字电子时钟语音播报系统摘要 本文介绍了基于ISD4004的语音播报系统。系统由STC89系列单片机为核心，控制整个系统的协调工作。为了使用方便，本系统采用了两种的显示方式，LCD1602和上位机，LCD1602主要用于遥控调节时间时的显示，上位机的显示界面相当简洁，达到一目了然的效果。语音播报核心芯片是ISD4004芯片，该芯片能够实现多电平保存，并且掉电不丢失等优点。为了方便远距离调节时

2、间，本系统使用按键作为时间调节的工具。同时为了让系统时间运行精度更高，该系统采用了PCF8563作为时钟芯片，该芯片运行比较稳定，而且功耗低。单片机先将时钟芯片进行初始化，然后将读回来的数据显示在液晶屏上，并通过ISD4004进行播报。同时为了实时监测周围环境的温度，本系统采用DS18B20芯片作为温度采集器。关键词 单片机 数字时钟 DS18B20 PCF8563 74HC595 ISD4004语音播报 上位机 无线遥控 一、 系统整体设计方案1.1 系统整体功能本系统采用时钟芯片PCF8563和语音芯片ISD4004实现数字语音数字时钟，采用74HC595驱动数码管实时显示。1.2 系统实
