摘要
目的设计一种低功耗物联网射频识别(RFID)接入方案实现生理参数与医院信息系统(HIS)融合。方法采用低功耗ARM作为主控芯片、驱动PN532芯片作为RFID读写芯片来读取标签数据,再通过查找SD卡中的汉字库,将患者的信息显示于LCD液晶屏上,最后通过Wi-Fi模块将所有数据传至护士站。结果经测试,本系统可准确采集腕带中的患者信息,并清晰显示于LCD屏幕上,数据经绑定后快速连接Wi-Fi网络。结论本系统具有准确、快速、稳定以及低功耗等优点,非常适合应用于物联网传感器节点的设计方案中,具有广阔的发展空间。
Objective To realize integration between physiological parameters of patients and HIS by designing a RFID-based low-power solution accessing to TOt （Things of Internet）. Methods After reading the target information by low-power ARM （master chip） and drive PN532 chip （RF1D reader and writer chip）, the patients information would be displayed on the LCD screen through searching Chinese font in SD. Then all data was uploaded to nurse station by Wi-Fi module. Results The test result showed that this system can capture patients information accurately from wristbands, and display it clearly on LCD screen. Then these bound data was quickly connected to Wi-Fi. Conclusion This system has advantages of fast, accurate, stable and low-power which is very suitable for sensor node and will enjoy wide development space in the future.
