摘　　要：设计一套基于三层C/S架构的分布式心音采集及时域分析系统。该系统由单通道心音采集仪、客户端、服务器组成。单通道心音采集仪将采集到的心音数据以TXT文档形式存入SD卡,并通过USB接口将数据上传到客户端。客户端通过TCP协议与服务器进行通信,并利用Socket方式向服务器提交采集到的心音数据。服务器将客户端提交的数据存储在数据库中。心音时域分析算法在MATLAB中进行开发,并通过com builder将其转换为com组件,供服务器软件调用,实现心音的分析。服务器将分析结果图片存入数据库,供用户查询。This paper focuses on a distributed heart sound acquisition and time-domain analysis system based on three-Layer C/S architeture. This system is comprised of single-channel heart sound acquisition instnament, client and server. The single-channel heart sound acquisition instrument stores heart sound data in an SD card in TXT files, and it uploads the files to the client via USB. The cli- ent communicates with the server via TCP, and it uploads heart sound data via Socket on the other hand. The server stores the data up- loaded by the client into the database. The time-domain analysis program is made in Matlab, and then transformed into a corn component by Corn Builder. The server fulfils the purpose of heart sound analysis in time-domain by calling the com component. And the server stores the pictures of analyzed results,which is queried by users, into the database.
