【摘要】：當(dāng)今社會，物聯(lián)網(wǎng)的發(fā)展得到人們越來越多的關(guān)注。作為物聯(lián)網(wǎng)應(yīng)用中的重要領(lǐng)域，智能家居系統(tǒng)成為相關(guān)學(xué)者及產(chǎn)業(yè)鏈上各廠商爭相研究的對象。節(jié)能、便捷、低成本的生活方式使人們對智能家居系統(tǒng)提出了更高的要求，其中提高系統(tǒng)的穩(wěn)定性、降低系統(tǒng)功耗和增強可擴展性成為智能家居系統(tǒng)的研究重點。 本文是對基于ZigBee通信技術(shù)的智能家居系統(tǒng)的研究，，主要研究ZigBee路由協(xié)議的改進及智能家居系統(tǒng)的設(shè)計方案，解決傳統(tǒng)路由協(xié)議路由開銷高、節(jié)點能耗大及關(guān)鍵節(jié)點能量耗盡死亡所造成的系統(tǒng)網(wǎng)絡(luò)分割或癱瘓；應(yīng)用改進的路由協(xié)議及ACE反應(yīng)器框架設(shè)計出穩(wěn)定性好，擴展性強的新型智能家居系統(tǒng)。 本文首先介紹了課題來源及研究現(xiàn)狀，闡述了ZigBee技術(shù)的基本原理及現(xiàn)有路由協(xié)議的優(yōu)缺點，為選用ZigBee技術(shù)作為智能家居系統(tǒng)的通信手段提供了理論基礎(chǔ)。其次論文在現(xiàn)有的ZBR路由協(xié)議的基礎(chǔ)上，提出了改進的ZigBee路由協(xié)議M-ZBR，主要改進節(jié)點地址分配方式和網(wǎng)絡(luò)路由選擇機制，添加節(jié)點能量均衡策略。仿真結(jié)果表明在路由開銷和節(jié)點能量消耗方面M-ZBR明顯低于樹路由協(xié)議和ZBR路由協(xié)議。將此協(xié)議設(shè)計應(yīng)用于智能家居的ZigBee網(wǎng)絡(luò)通信模塊可大大提高系統(tǒng)的穩(wěn)定性并降低節(jié)點的功耗。然后本文介紹了智能家居系統(tǒng)的設(shè)計方案，主要包括ZigBee通信模塊設(shè)計、智能網(wǎng)關(guān)設(shè)計、中控機設(shè)計以及基于ACE反應(yīng)器框架的系統(tǒng)軟件設(shè)計。其中中控機為智能家居系統(tǒng)提供了軟件運行平臺及協(xié)議轉(zhuǎn)換策略；ACE框架簡化了系統(tǒng)軟件的實現(xiàn)，使系統(tǒng)運行穩(wěn)定、擴展性增強。最后論文對所設(shè)計的智能家居系統(tǒng)進行了測試，結(jié)果顯示系統(tǒng)實現(xiàn)了預(yù)期功能，且運行穩(wěn)定。
[Abstract]:Nowadays, people pay more and more attention to the development of the Internet of things. As an important field in the application of the Internet of things, smart home system has become the research object of related scholars and manufacturers in the industrial chain. The low cost life style makes people put forward the higher request to the smart home system, among which improving the stability of the system, reducing the power consumption and enhancing the expansibility of the system become the research focus of the intelligent home system. This paper is about the research of smart home system based on ZigBee communication technology. It mainly studies the improvement of ZigBee routing protocol and the design scheme of smart home system, which solves the high routing overhead of traditional routing protocol. Using the improved routing protocol and ACE reactor framework, a new type of smart home system with good stability and expansibility is designed. This paper first introduces the source of the subject and the current research situation, expounds the basic principle of ZigBee technology and the advantages and disadvantages of the existing routing protocols. This paper provides a theoretical basis for choosing ZigBee technology as the communication means of smart home system. Secondly, based on the existing ZBR routing protocol, An improved ZigBee routing protocol, M-ZBR, is proposed, which mainly improves node address allocation and network routing mechanism. The simulation results show that the M-ZBR is obviously lower than the tree routing protocol and the ZBR routing protocol in the aspects of routing overhead and node energy consumption. The design of this protocol can be applied to the ZigBee network communication module of smart home. The stability of the system is greatly improved and the power consumption of the node is reduced. Then this paper introduces the design scheme of the smart home system. It mainly includes ZigBee communication module design, intelligent gateway design, The design of the central control machine and the system software design based on the ACE reactor frame, in which the central control machine provides the software running platform and the protocol conversion strategy for the intelligent home system. The framework simplifies the realization of the system software and makes the system run stably. Finally, the smart home system is tested, and the result shows that the system achieves the expected function and runs stably.
