【摘要】：隨著生活質(zhì)量的提高，家居對(duì)人們來說已經(jīng)不只是簡(jiǎn)簡(jiǎn)單單的物質(zhì)空間，而是一個(gè)舒適、高度安全、美觀方便以及智能的居住環(huán)境。家電的自動(dòng)化、智能化，資源管理及購物方式的網(wǎng)絡(luò)化，通信設(shè)施的先進(jìn)化，信息終端的高效化等等都是人們所期望的。由此可知，家居智能化已經(jīng)成為一種趨勢(shì)。 本文實(shí)現(xiàn)了基于ZigBee的智能家居網(wǎng)絡(luò)，在此網(wǎng)絡(luò)的基礎(chǔ)上設(shè)計(jì)了幾種節(jié)能方法。本智能家居網(wǎng)絡(luò)分為內(nèi)網(wǎng)和外網(wǎng)，外網(wǎng)是由智能終端、網(wǎng)關(guān)和具有公網(wǎng)IP的服務(wù)器組成。本文以mini6410為硬件平臺(tái)搭建了智能網(wǎng)關(guān)，采用NAT穿越技術(shù)實(shí)現(xiàn)網(wǎng)關(guān)與智能終端的通信。內(nèi)網(wǎng)為整個(gè)基于ZigBee的傳感器網(wǎng)絡(luò)。ZigBee是一種標(biāo)準(zhǔn)，，該標(biāo)準(zhǔn)定義了一系列低速率、短距離無線通信所需要的通信協(xié)議。目前得到廣泛應(yīng)用和推廣的ZigBee協(xié)議是ZigBee2007協(xié)議。TI公司推出的Z-Stack協(xié)議棧和CC2530芯片完全兼容ZigBee2007協(xié)議。本智能家居網(wǎng)絡(luò)的內(nèi)網(wǎng)就是基于TI的Z-Stack協(xié)議棧在以CC2530為主要芯片的平臺(tái)上實(shí)現(xiàn)的。 能耗問題是智能家居網(wǎng)絡(luò)在應(yīng)用過程中面臨的關(guān)鍵問題，如何在不影響性能的基礎(chǔ)上延長(zhǎng)電池的使用壽命是本文研究的重點(diǎn)。本文研究的節(jié)能方法是以內(nèi)網(wǎng)即ZigBee傳感器網(wǎng)絡(luò)為研究對(duì)象。首先從協(xié)議棧的角度出發(fā)尋找節(jié)能的途徑。除此之外還提出了路由節(jié)點(diǎn)輪換機(jī)制和數(shù)據(jù)包壓縮技術(shù)實(shí)現(xiàn)ZigBee網(wǎng)絡(luò)的節(jié)能。路由節(jié)點(diǎn)輪換機(jī)制根據(jù)電量來變換當(dāng)前節(jié)點(diǎn)的父節(jié)點(diǎn)，防止某個(gè)節(jié)點(diǎn)電量過快耗盡。數(shù)據(jù)包壓縮技術(shù)利用了無線網(wǎng)絡(luò)的中間節(jié)點(diǎn)，中間節(jié)點(diǎn)將收到的信息進(jìn)行壓縮后再轉(zhuǎn)發(fā)出去。最后匯聚節(jié)點(diǎn)處統(tǒng)一進(jìn)行解碼，可以大大降低了中間節(jié)點(diǎn)發(fā)送數(shù)據(jù)包的次數(shù)。 經(jīng)過大量的測(cè)試發(fā)現(xiàn)，本文實(shí)現(xiàn)的基于ZigBee的智能家居網(wǎng)絡(luò)使用簡(jiǎn)單、能耗低，很好的克服了許多智能家居網(wǎng)絡(luò)的缺點(diǎn)，具有很高的應(yīng)用價(jià)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.
