摘要
本文根据人体脉搏信号特征设计了一个脉搏检测装置,能够获得不失真的人体脉搏波形并且能在PC机上显示,以便医护人员观察和研究。该脉搏波检测系统的最大特点是利用DAQ数据采集卡采集信号并用LabVIEW虚拟仪器的操作面板及相应的程序,显示出脉搏的波形和脉搏频率以及实现波形的存储、回放和异常信号报警等功能。相比与传统的仪器,虚拟仪器并不依赖于硬件,其性能很大程度上由应用软件决定,大大缩短系统的开发时间和成本,提高生产效率高达4～10倍。
In this paper, we designed a detection device system of pulse wave basing on the signal characteristics of the human pulse wave in order to acquire and display a wave watching by the doctor, which is like the body pulse wave very much. The most significant feature of the system is that the pulse wave shape can be displayed,save and Waveform playback and alarmed to exceptional wave on the virtual panel by software based on LabVIEW. Compared with traditional instruments, virtual instrument is not dependent on hardware, to a large extent, on the performance of its applications, which will reduce significantly system development time and costs and improve productivity as much as 4 to 10 times.
