摘　　要：针对我国人口老龄化和医疗资源紧张问题,设计了一种基于900MHz UHF RFID技术的无线脉搏血氧传感系统。系统整体构架由光电传感器、微处理器、RFID标签、RFID阅读器和上位机组成。光电传感器和微处理器实时采集和处理脉搏血氧信号,RFID标签和阅读器实现数据无线通信,最终通过上位机完成数据收集和界面显示。实验结果表明:所设计系统与临床用血氧检测仪具有良好的一致性,且具有无线传输和低功耗的特点,为无线生物传感芯片的设计开发提供了参考。To relieve social issues caused by population-aging and insufficient medical resources,a wireless pulse oximetry monitoring system based on 900 MHz UHF RFID technique is designed. The whole system is composed of photoelectric sensor, microprocessor,RFID tag,RFID reader and host computer. Photoelectric sensor and microprocessor realtime acquire and process pulse and oxygen saturation signal,RFID tag and reader realize wireless communication of data. Finally,the host computer achieves data acquisition and real-time displays. The experimental results show that the designed monitoring system can has characteristics of wireless transmission,and low power consumption provide a reference for design and development of wireless biosensing chip.
