医疗监护无线传感器网络的研究

Research of Wireless Sensor Network for Medical Care

无线传感器网络具备传感、计算和无线通信等能力,如何将它应用到传统的医疗监护领域是一个很大的挑战.无线传感器网络的实现难点在于网络体系机构、操作系统、通信协议和应用软件等方面的设计.设计了一种心电医疗监护无线传感器网络,它对于医院病人的心电实时监护和临床医学诊断具有重要的实际意义,详细介绍了无线传感器网络体系结构和系统软硬件设计,尤其在节点硬件和通信协议两方面进行了深入的阐述.

The wireless sensor network technology combines the capabilities of sensing, computation and wireless connection. It is an interesting yet challenging job to apply the wireless sensor network technology on the traditional healthcare field. Realizing a wireless sensor network system presents very significant challenges, especially at the architectural, the operation system, the communication protocol and the application software support. We present a wireless sensor network system dedicated to remote continuous real-time cardiac arrhythmias detection and diagnosis. The aim of the system is to monitor people that suffer from heart arrhythmias; and therefore, living a normal life while feeling safe at the same time. The architecture of the system is presented. Some hardware and software implementation details are explained showing how the solution can be effectively implemented and deployed into a system. Moreover, special attention is paid to two aspects： hardware design of nodes and communication protocol of the wireless sensor network.
