基于无线局域网技术的心电监护网络系统的研究

目的：研究利用无线局域网（WLAN）技术进行心脏病患者心电图像监视系统。方法：利用Labview软件采集处理心电信号，当心脏病患者出现紧急情况时，发出报警信息，并可通过WLAN将患者的心电监视图像以及心电数据传送到救治医院或社区医院，对心脏病患者进行初步诊断及远程救助。结果：基于Labview的软件心电采集系统能够准确优质的采集心电信号；调整后的模拟信号调理电路可以进行更好的高速数字信号处理工作。结论：基于Labview图形编程，可以使心电监护系统具有非常大的灵活性，并根据不同的要求调整信号处理策略。本研究设计的心电监护网络系统也是研究心电信号检测新方法的理想实验平台。

ECG monitoring network system based on WLAN

Objective： The paper mainly Studies using WLAN wireless network on the patients to monitor ECG image system. Methods： The use of labview software acquisition and processing ECG signals,when the heart disease patients are found in an emergency, sending alarm information,and sending the image of monitoring patients and ECG data through the Wlan wireless network to the community or hospital,making initial diagnosis and remote assistance on cardiac patients. Results： The results reveal that the software based on Labview can acquire ECG signals accurately;after adjustment for analog signal conditioning circuit,the circuit would process digital signals better and high-speed. Conclusion： The system has a very large flexibility based on Labview graphical programming, according to different requirements to adjust the signal processing strategies. The system is the ideal experimental platform as a new detection method of ECG.
