摘要
利用虚拟仪器技术构建一台实验动物生理信号检测与处理系统。该系统设有八个通道,可分别对实验动物的体温、呼吸、血压、心电等生理信号进行检测和处理。利用LabWindows/CVI软件结合PCI-9112数据采集卡对动物的生理信号进行实时、高速的采集,同时借助计算机的强大功能对采集到的数据进行显示、处理、存储和回放。实验证明系统运行稳定,检测精度高,有一定的实用价值。
Based on virtual instrument technology, it design a data detection and procession device which can synchronously display eightchannel experimental animals＇ physiological signals,such as the body temperature, respiration, blood pressure, electrocardiogram and so on. By use of LabWindows / CVI and PCI-9112 data acquisition card, it＇s able to acquire animals＇ physiological signals. Meanwhile, it can display, process, storage and playback the acquired datas with the help of the PC＇s powerful function. The application shows that this system runs stably and accurately. The technology and methods adopted in the system are worthy of using abroad.
