WiFi技术在医院物联网中的应用研究

Research on WiFi Technology for Medical-use Internet-of-Things

针对Wi Fi技术在医院物联网中的应用,通过ARM+Wi Fi So C的方式,设计基于Wi Fi技术的医院物联网传感终端,在小体积低成本的嵌入式系统上实现Wi Fi功能。在物理层开发Wi Fi芯片的驱动程序,在网络层和传输层移植嵌入式TCP/IP协议栈,并开发上层应用实现数据采集和Socket发送;结合医院物联网的具体应用,将所开发的Wi Fi体温采集终端投入到临床应用中,经验证,Wi Fi数据采集终端达到了预期的效果。

Aiming at the application of Wi Fi technology in hospital in IOT,this article outlines the research background and the research status at home and abroad,after that it introduces the relevant knowledge and theory of the Internet of Things and Wi Fi technology. IOT sensing terminal was designed based on Wi Fi technology and Wi Fi technology into a small volume and low-cost embedded systems was introduced in the form of ＂ ARM ＋ Wi Fi So C＂. The driver for Wi Fi chip on the physical layer and transplanted embedded TCP/IP protocol stack on the network layer and the transport layer was developed,after that the upper layer application was also developed which could send acquisited data by Socket. The system reaches the primary goal by testing.
