基于Zigbee Pro的多节点组网技术的研究
发布时间:2018-08-18 09:20
【摘要】:自2002年10月Zigbee Alliance成立以来,Zigbee协议从Zigbee 2004、Zigbee2006发展到Zigbee Pro(即Zigbee 2007)。作为物联网技术的重要组成部分,Zigbee技术广泛应用于军事、汽车、医疗、智能家居等领域,Zigbee网络的稳定性、可靠性和Zigbee网络节点容量也成为人们关注的热点。在使用Zigbee节点组网的过程中,我们发现随着节点数量的增加,Zigbee网络开始出现节点随机掉线现象:当节点达到一定数量时,新增的节点会随时上线,在线的一个或几个节点随时会掉线,Zigbee网络的拓扑结构会随之变化,网络变得不稳定;此时,Zigbee网络中的感知节点(温度、湿度、压力、光照、二氧化碳等)和控制节点(GPIO)等无法正常工作,从而导致该网络无法正常运行。本文根据Zigbee的基本原理,在大量可重复实验数据的基础上,分析了Zigbee网络节点掉线的原因,找到了本实验环境下Zigbee网络稳定工作时的最大节点容量,提出了一种改进Zigbee网络节点容量的方法。
[Abstract]:Since the establishment of Zigbee Alliance in October 2002, the Zigbee protocol has evolved from Zigbee 2004 / Zigbee2006 to Zigbee Pro (Zigbee 2007). As an important part of the Internet of things, Zigbee technology has been widely used in military, automobile, medical, smart home and other fields, such as the stability, reliability and Zigbee network node capacity. In the process of using Zigbee nodes to form a network, we find that with the increase of the number of nodes, the random drop of nodes begins to occur in the network: when the number of nodes reaches a certain number, the new nodes will go online at any time. One or more nodes on the line will drop the topology of the Zigbee network at any time, and the network will become unstable; at this point, the sensing nodes in the Zigbee network (temperature, humidity, pressure, light, etc.) Carbon dioxide, etc.) and control nodes, such as (GPIO), do not work properly, resulting in the network not functioning properly. According to the basic principle of Zigbee and on the basis of a lot of repeatable experimental data, this paper analyzes the reason of node dropping in Zigbee network, and finds out the maximum node capacity of Zigbee network when it works stably in this experimental environment. A method to improve the node capacity of Zigbee network is presented.
