基于无线射频技术的多功能监护仪管理系统

Multi⁃function monitor management system based on radio frequency technology

多功能监护仪是一种实用的医疗监控设备,为了实现多功能监护仪在物联网环境下的综合应用,文中基于无线射频技术设计了一套多功能监护仪管理系统。在监护仪信息的传输方面,系统采用微控制器与传感网络构建了包含传感器层、网络层、互联网层、服务层的综合管理系统。为了保证RFID网络的正常通信,同时建立了传感网络模型,并确定出增益等参数的合理数值。实验测试结果表明,该监护仪管理系统对被测人员的运动识别准确率高于89%,心率检测准确率偏差符合医用标准,能够将呼吸暂停预警时间提高至约4 s。

Multifunctional monitor is a kind of practical medical monitoring equipment.In order to realize the comprehensive application of multi⁃functional monitor in the environment of Internet of things,this paper designs a set of multi⁃functional monitor management system based on radio frequency technology.In the aspect of monitor information transmission,the system uses microcontroller and sensor network to build a comprehensive management system including sensor layer,network layer,Internet layer and service layer.In order to ensure the normal communication of RFID network,the sensor network model is established,and the reasonable value of parameters such as gain is determined.The experimental results show that the accuracy of the monitor management system is higher than 89%,the deviation of the heart rate detection accuracy meets the medical standard,and the warning time of respiratory pause can be increased to about 4 s.
