摘要
数字存储式自动应答录音系统是将微电子技术﹑A/D转换技术﹑信息处理等技术综合一体的现代新技术,它与传统的电话机紧密结合成为一种新的通讯工具,广泛应用于家庭、办公等场所。
数字存储式自动应答录音系统主要由A/D转换芯片、存储芯片以及完成功能控制的单片机控制部分组成。该系统可以用于电脑自动应答、数字点歌、自动音频服务等方面。数字存储式自动应答录音机由于功能多,使用方便而备受用户的欢迎,也是电话机中近年高速发展的新型科技产品。
本系统是针对数字存储式自动应答录音系统进行研究的。为了阐明用单片机控制录音的方法,对录音模块单元如何进行、A/D怎么转换,消息怎样存储进行了研究。本文在给出数字存储式自动应答录音硬件设计的基础上,详细分析了数字存储式自动应答录音系统的软件控制方法。本系统介绍用单片机进行控制,利用ISD2590芯片设计实现的一种数字式自动答录系统。该系统具有一定程度的智能化,且实现简单,具有较大的可扩充性。

Abstract
The digital memory type auto answer recording channel is the microelectron technology,It with the traditional telephone in close integration with into one kind of munication facilities, widely applies to place and so on family, work.。
The digital memory type auto answer recording channel mainly by the A/D transformation chip, the memory chip as well pletes the function control the monolithic integrated circuit control section to posed. This system may use in aspect and so puter auto answer, digital song, automatic audio frequency service. The digital memory type auto answer tape recorder are many as a result of the function, the easy to operate prepares user's e, also was in the telephone the recent years high speed development new technical product.。
This system is aims at the digital memory type auto answer recording channel to conduct the research. In order to expound with the monolithic integrated circuit control sound recording method, how to records the module unit to carry on, A/D how transforms, how did the news save has conducted the research. This article in produces in the foundation which the digital memory type auto answer sound recording hardware designs, multianalysis numeral memory type auto answer recording channel software control method。This system introduced carries on the control with the monolithic integrated circuit, digital automatically answe
