远程无线心电监护系统的软件设计

摘要

Heart diseases often happen suddenly and are with high fatality. In order to detect the illness in time, one needs to conduct effective monitoring on the patients suffered from heart diseases. The software design of remote wireless electrocardiogram (ECG) monitoring system is presented in this paper. The bottom program of MC9S12XS128 is used to collect the ECG data and control the AT injunction to the GPRS module, thus realizing the wireless transmission of ECG data. The system software is programmed by LabVIEW which has graphic programming environment, including the analysis, disposal, display and storage of the ECG data. The operator can measure the ECG quality of the patient real time for early diagnosis and treatment. An auto-alarm system is also designed.%心血管疾病具有突发性和高危险性，为了及时发现病情，需要对患者进行有效监护。文中设计了一套远程心电监护系统软件，通过对MC9S12XS128单片机底层程序的设计，完成了对心电信号数据的采集和GPRS模块的AT指令控制，由此实现心电信号数据的无线传输。操作简单、界面友好的监护系统部分采用了LabVIEW图形化编程环境，对采集到的心电信号进行分析、处理、显示以及存储，操作者可以实时监测被测者的心电情况，便于及时做出诊断，及早治疗，同时设置了自动报警系统。
