摘要
人体脉搏波包含着丰富的生理信息,对其进行测量与分析具有较高的实用价值。本文提出了一种基于LabView虚拟仪器平台的脉搏测试仪设计方案,使用压电式振动传感器获取人体脉搏波信号,利用声卡或数据采集卡对这些信号进行采集,在Labview平台上完成信号的再次处理、进一步的分析及人机界面的构建。本设计充分利用了PC资源,使用方便,结果准确。
Human＇s pulse wave contains rich physiological information, thus measuring and analyzing about it has much practical values. In this article, we propose a design of pulse wave measuring based on Labview. We use piezoelectric pressure transducer to obtain human pulse wave signals and PC sound card or data collecting card to collect these signals. Then with l_abview visual instrument on PC, further processing and analysis about the data are finished. In general, this design is convenient and accurate.
