【摘要】：随着社会经济水平和科学技术的不断进步,人口老龄化程度也随之加剧,接踵而来的是一系列严峻的社会问题,如何保障老年人的生命健康成为社会各界关注和研究的重点。体域网(Body Area Network, BAN)这一名词应运而生,它由放置在人体上或体内的若干个传感器构成,利用传感器采集人体的生理体征参数,并将此数据传输至客户端供家属及医疗人员监测。本文的主要内容是利用嵌入式技术,完成一个嵌入式网关的设计和实现。实现将BAN网络中传感器采集到的人体生理体征参数通过嵌入式网关的作用传输至Internet,设计和实现分为硬件和软件两个方面。(1)硬件方面的工作包括微控制器、串口模块、以太网模块和一些外围模块的器件选型和电路设计。串行接口模块和以太网模块是两个主要通信模块,其中,串行接口模块实现的是将数据从BAN网络的串口设备中进行接收并存储,以太网通信模块实现的是将串口接收来的数据从存储器中取出,再通过以太网模块发送出去。(2)软件方面的工作具体分为四个部分：串行接口模块通信的实现、以太网模块通信的实现、TCP/IP协议栈的实现和服务器的实现。首先,通过定义相同串口传输的报文格式,可以实现数据在串口之间的接收和发送。其次,由以太网模块通过硬件驱动程序实现以太网帧的接收和发送。然后,利用TCP/IP协议栈中的一些协议将数据封装并处理,根据系统的需求选择了TCP、IP、ICMP和ARP协议,并对它们进行了简化,然后组合成为以太网帧。最后,实现一个服务器,实现与以太网的TCP连接并接收数据,再设计一个数据库,用来存储这些数据,服务器可以访问数据库并将数据插入到数据库中。至此,网关系统完成了将BAN网络采集到的老人生理体征参数传输到服务器的功能,最终将数据存放在了数据库中。如此,便可通过Web浏览器查看老年人的生理体征参数,这样的设计可以使不在本地的家属和医护人员及时获得老人身体生理参数数据,并根据具体情况进行及时、准确的照顾和救治。
[Abstract]:With the social and economic level and the continuous progress of science and technology, the degree of population aging is also aggravated, followed by a series of severe social problems. How to protect the life and health of the elderly has become the focus of attention and research from all walks of life. The noun of Body Area Network (BAN) arises at the historic moment, and it is placed in the human body The main contents of this paper are the design and implementation of an embedded gateway. The main content of this paper is to use embedded technology to complete the design and implementation of an embedded gateway. The body physiology of sensors in BAN network is realized. The sign parameters are transmitted to Internet by the function of the embedded gateway. The design and implementation are divided into two aspects of hardware and software. (1) the work of hardware includes the device selection and circuit design of the microcontroller, the serial port module, the Ethernet module and some peripheral modules. The serial interface module and the Ethernet module are the two main communication modules. In the serial interface module, the data is received and stored from the serial port device of the BAN network. The Ethernet communication module realizes the data received from the serial port from the memory and then sent out through the Ethernet module. (2) the work of the software is divided into four parts: the realization of the serial interface module communication. The realization of Ethernet module communication, the implementation of the TCP/IP protocol stack and the realization of the server. First, by defining the message format of the same serial port, the data can be received and sent between the serial ports. Secondly, the Ethernet module is used to receive and send the Ethernet frame through the hardware driver. Then, the TCP/IP protocol stack is used in the protocol stack. Some protocols encapsulate and process data, select TCP, IP, ICMP, and ARP protocols according to the requirements of the system, simplify them and combine them into Ethernet frames. Finally, a server is implemented to connect TCP to Ethernet and receive data, and then a database is designed to store the data. The server can access the data. The server can access the data. The database and the data are inserted into the database. At this point, the gateway system has completed the function of transmitting the physical and physical parameters of the elderly collected by the BAN network to the server. Finally, the data is stored in the database. In this way, the physiological parameters of the elderly can be viewed through the Web browser, so that the design can not be in the local home. The genera and medical staff obtained timely data on physical parameters of the elderly, and promptly and accurately took care and treatment according to the specific circumstances.
