摘　　要：当今社会,心脏疾病已成为威胁人类健康的“头号杀手”。心血管类疾病一直伴随着我们人类,成为人们生活中最大的隐患,对人们的生命健康造成了严重的威胁。因此,为了提取反映心脏健康状况的定量的全方位的心音信息,利用先进的数字信号处理技术和计算机技术,以树莓派为中央处理器,通过被誉为“数学显微镜”的小波变换分析心音的各种成份时间,设计一套便捷的、高质量的心音采集系统,并与互联网信息连接,能够对心音信号波形进行显示。实验测试结果表明,该系统所提取的波形平滑,系统运行稳定,可以准确地判断出所采集的心音信号类型,这对于心血管疾病的预防有重大意义。In today’s society,heart disease has become the“number one killer”that threatens human health.Cardiovascular diseases have always been accompanied by our human beings and have become the biggest hidden danger in people’s lives,posing a serious threat to people’s lives and health.Therefore,in order to extract the quantitative and all-round heart sound information reflecting the health status of the heart,a set of convenient and high-quality heart sound acquisition system is designed by using advanced digital signal processing technology and computer technology,using raspberry pie as the central processor,and analyzing the various components of heart sound by wavelet transform known as“mathematical microscope”.The experimental results show that the waveform extracted by the system is smooth,the system is stable,and the type of heart sound signal can be accurately judged,which is of great significance for the prevention of cardiovascular disease.
