摘要
主要介绍了ZigBee技术在医疗监护系统中的应用,利用其短距离、低速率、低功耗、网络容量大且具有自组织、自愈功能的特点,提出了一种基于ZigBee技术的无线医疗监护系统解决方案。系统中,节点和网关设备之间所用的通信协议为802.15.4/ZigBee标准,系统硬件平台基于TI公司的CC2530芯片,软件平台基于TI公司的Z-Stack协议栈,终端节点上的温度及脉搏传感器采集人体的生理数据,通过无线传输最终实现医院对患者生理信息的采集和诊断。实验结果表明:节点采集传感器数据准确,无线传感器网络数据传输可靠。
The application of ZigBee technology in medical monitoring system is introduced, and a system used for wireless medical monitoring based on ZigBee technology is presented,by means of its characteristics of short-range,low-rate,low-power, large network capacity, self-organizing and self-healing. In this system, the close communication standards for nodes and base station equipment are 802.15.4/ZigBee, the system hardware platform is developed using the chip of TI＇s CC2530, software platform is developed based on TI＇s Z-Stack protocol stack. The physiological data of the human body which are collected by the temperature and pulse sensors are transferred to the hospital by the transmission of wireless network, and ultimately being used for the remote collection of patientsv physiological information and diagnosis of the patients. From the test results of the sensor network, it indicates that the sensor of nodes collects data precisely and the data transmission of wireless network is reliable.
