【摘要】：随着生活质量的提高，家居对人们来说已经不只是简简单单的物质空间，而是一个舒适、高度安全、美观方便以及智能的居住环境。家电的自动化、智能化，资源管理及购物方式的网络化，通信设施的先进化，信息终端的高效化等等都是人们所期望的。由此可知，家居智能化已经成为一种趋势。本文实现了基于ZigBee的智能家居网络，在此网络的基础上设计了几种节能方法。本智能家居网络分为内网和外网，外网是由智能终端、网关和具有公网IP的服务器组成。本文以mini6410为硬件平台搭建了智能网关，采用NAT穿越技术实现网关与智能终端的通信。内网为整个基于ZigBee的传感器网络。ZigBee是一种标准，，该标准定义了一系列低速率、短距离无线通信所需要的通信协议。目前得到广泛应用和推广的ZigBee协议是ZigBee2007协议。TI公司推出的Z-Stack协议栈和CC2530芯片完全兼容ZigBee2007协议。本智能家居网络的内网就是基于TI的Z-Stack协议栈在以CC2530为主要芯片的平台上实现的。能耗问题是智能家居网络在应用过程中面临的关键问题，如何在不影响性能的基础上延长电池的使用寿命是本文研究的重点。本文研究的节能方法是以内网即ZigBee传感器网络为研究对象。首先从协议栈的角度出发寻找节能的途径。除此之外还提出了路由节点轮换机制和数据包压缩技术实现ZigBee网络的节能。路由节点轮换机制根据电量来变换当前节点的父节点，防止某个节点电量过快耗尽。数据包压缩技术利用了无线网络的中间节点，中间节点将收到的信息进行压缩后再转发出去。最后汇聚节点处统一进行解码，可以大大降低了中间节点发送数据包的次数。经过大量的测试发现，本文实现的基于ZigBee的智能家居网络使用简单、能耗低，很好的克服了许多智能家居网络的缺点，具有很高的应用价值。
[Abstract]:With the improvement of quality of life, home is not only a simple material space for people, but also a comfortable, highly safe, beautiful and convenient living environment.The automation, intelligence, network of resource management and shopping mode, the advanced communication facilities and the high efficiency of information terminal are all expected by people.From this, home intelligence has become a trend.The intelligent home network based on ZigBee is implemented in this paper, and several energy saving methods are designed on the basis of this network.The smart home network is divided into intranet and extranet, which is composed of intelligent terminal, gateway and server with public network IP.In this paper, the intelligent gateway is built based on mini6410, and the communication between gateway and intelligent terminal is realized by NAT traversal technology.The intranet is a standard for the whole sensor network based on ZigBee. ZigBee defines a series of communication protocols for low rate, short range wireless communication.At present, the widely used and popularized ZigBee protocol is the Z-Stack protocol stack and CC2530 chip which is completely compatible with ZigBee2007 protocol.The intranet of this smart home network is implemented on the platform of CC2530 based on TI Z-Stack protocol stack.Energy consumption is a key problem in the application of smart home network. How to extend the battery life without affecting the performance is the focus of this paper.The energy saving method studied in this paper is that the inner network is the ZigBee sensor network.First of all, from the point of view of protocol stack, to find ways to save energy.In addition, the routing node rotation mechanism and packet compression technology are also proposed to achieve energy saving in ZigBee networks.The routing node rotation mechanism transforms the parent node of the current node according to the quantity of electricity to prevent a node from running out too quickly.Packet compression uses the intermediate nodes of wireless networks, which compress the information received and forward it.Finally, the convergent node can be decoded uniformly, which can greatly reduce the number of packets sent by the intermediate node.After a lot of tests, it is found that the smart home network based on ZigBee is simple to use and low in energy consumption. It can overcome the shortcomings of many smart home networks and has high application value.
