摘要
针对老年人、残疾人、婴幼儿等弱势群体的远程实时监护和关爱的要求,文中设计并实现了基于ZigBee无线通信技术和嵌入式以太网技术的低成本的智能网络关爱系统.应用ZigBee技术,通过无线传输方式实现健康参数测量节点、安全监控节点和视音频交互节点与家庭网关的数据传输,降低了系统功耗,提高了系统的灵活性.利用嵌入式以太网技术,将家庭网关作为一个Web服务器使系统接入互联网,实现用户通过互联网对测量节点测量数据的直接访问.通过在实际场景下的测试,证明了该系统具有很高的实用性.
Based on ZigBee wireless communication technology and embedded Ethemet technology, this paper designs and implements a low- cost imelligent network caring system for the requirement of real- time remote monitor and caring for the elder, the disabled, the infants and other caring needing groups. Employing ZigBee technology, we realize the data transmission between the nodes of detecting physiology parameters, safety monitoring, video ＆ audio interactive and home gateway. It reduces the power consumption and increases the flexibility. Utilizing the embedded Ethernet, the system is connected to the Internet and via the Web server provided by the home gateway, the user could get the data of sensor nodes immediately. With the system testing in a real condition, the system is verified with the remarkable practicability.
