摘　　要：基于心冲击(Ballistocardiogram,BCG)信号的产生原理,提出了一种基于高精度A/D转换模块的BCG信号检测系统.文中详细介绍了该系统的硬件组成、接口时序及软件实现过程.以同步检测的单通道ECG信号为时间基准,与降噪处理后的BCG信号进行了对比验证,结果表明两种信号节律一致,且BCG信号波形特征明显,验证了系统设计的正确性.该系统采用无创检测方式,增强了便携性和抗干扰能力,便于心脏机械活动的日常记录,为其应用到心脏病人长期家庭监护提供了硬件基础.According to the principle of Ballistocardiography （BCG） signals, a measuring device based on high-precision A/D conversion module was presented. The systematic basic composition, the time sequence and the realization process of software were detailed introduction. The experimental results showed that the rhythm of the BCG and synchronized lead I ECG signals is consistent, and wave characteristic of BCG signals is significant, which verified the correctness of the systematic design. A non-invasive method was adopted, which enhanced portability and anti-jam capabilities, and made it easy for daily monitoring cardiovascular mechanical activity. It provided a hardware foundation for long-term home monitor for heart patients.
