一种体域网无线心电监护系统的研制与测试

摘要

With the rapid increase of older people in China,the problem of elder people's chronic diseases and their health monitoring requirement outside hospital become more and more important. To face such challenge,the body area network sys-tem,a new kind of health care monitor,is needed to build up. This system is a small network based on IOT and sensor technol-ogies. A design scheme of body area network wireless electrocardiogram monitoring system is described in this paper. The patient system and pre-warning system are introduced emphatically. The portable electrocardiogram detecting blockis adopted in the pa-tient block to collect patient's electrocardiogram signal. The bluetooth short distance wireless communication technology is em-ployed to transmit the real-time electric signal to smartphone. The results of three iterms tested in the hospital environment are given in this paper.%随着中国老龄化和家庭空巢化的加剧，患有慢性疾病的老人在医院外的健康监护问题变得日益突出。这就需要人们能够设计出有别于传统医疗仪器的新系统，这样的新系统称为体域网系统。论述了体域网无线心电监护系统的设计方案，重点介绍了患者系统以及预警系统的构成。患者系统采用便携式心电检测模块来采集患者的心电信号；蓝牙短距无线通信技术用于将实时心电信号传输到智能手机；预警系统能接收患者系统发送的心电信号。最后给出了在医院环境中对系统进行的三项测试结果。
