摘　　要：心音和脉搏是反映人体生理及病理的两项重要指标,这里提出了基于单片机和PC机的心音、脉搏信号集成采集系统方案,设计了以单片机为核心的前端信号采集器,将心音和脉搏信号转换为数字量并通过串行通信口传送给上位PC机,在上位机应用程序窗口进行脉搏、心音信号波形的显示。The heart sounds and the pulse are two important indicators which reflect people s physiology and pathology,this paper proposed a heart sounds,pulse-signal integrated acquisition system based on PC and microcontroller,and designed front-end signal acquisition device which used MCU as the core,the heart sounds and pulse signal are converted to digital signal and transmitted to the Host PC by serial communication port,the host computer application s window displays pulse,heart sounds signal wave.

关 键 词：心音 脉搏 单片机 A/D转换 串口通信
