【摘要】:当今社会,物联网的发展得到人们越来越多的关注。作为物联网应用中的重要领域,智能家居系统成为相关学者及产业链上各厂商争相研究的对象。节能、便捷、低成本的生活方式使人们对智能家居系统提出了更高的要求,其中提高系统的稳定性、降低系统功耗和增强可扩展性成为智能家居系统的研究重点。 本文是对基于ZigBee通信技术的智能家居系统的研究,,主要研究ZigBee路由协议的改进及智能家居系统的设计方案,解决传统路由协议路由开销高、节点能耗大及关键节点能量耗尽死亡所造成的系统网络分割或瘫痪;应用改进的路由协议及ACE反应器框架设计出稳定性好,扩展性强的新型智能家居系统。 本文首先介绍了课题来源及研究现状,阐述了ZigBee技术的基本原理及现有路由协议的优缺点,为选用ZigBee技术作为智能家居系统的通信手段提供了理论基础。其次论文在现有的ZBR路由协议的基础上,提出了改进的ZigBee路由协议M-ZBR,主要改进节点地址分配方式和网络路由选择机制,添加节点能量均衡策略。仿真结果表明在路由开销和节点能量消耗方面M-ZBR明显低于树路由协议和ZBR路由协议。将此协议设计应用于智能家居的ZigBee网络通信模块可大大提高系统的稳定性并降低节点的功耗。然后本文介绍了智能家居系统的设计方案,主要包括ZigBee通信模块设计、智能网关设计、中控机设计以及基于ACE反应器框架的系统软件设计。其中中控机为智能家居系统提供了软件运行平台及协议转换策略;ACE框架简化了系统软件的实现,使系统运行稳定、扩展性增强。最后论文对所设计的智能家居系统进行了测试,结果显示系统实现了预期功能,且运行稳定。
[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.
