【摘要】：随着国民物质文化水平的日益提高,精神质量亟待改善。飞速发展的科技、提倡智能化物联网的热潮、快速的生活节奏、中国式的市场化居家需求等一些列内外因素大大加快了智能家居的产生和发展。虽然智能家居概念的提出由来已久,由于种种缘山,目前还不能够达到与时俱进,满足人民日益提高的生活需求。所以研究设计和优化智能家居系统具有现实意义。可以说智能家居系统是大数据、物联网、人机交互、人工智能技术的产物,也是人类热爱生活,追求高端大气上档次生活质量的时代产物。本文以ARM9为硬件核心模块linux (ubuntu)为嵌入式操作系统,设计以温度、湿度、光照、气体等一系列传感器结合zigbee网络数据收发模块的家居节点,架构以嵌入式微处理器为核心的WEB服务器网关的网络环境,室内使用采用新一代协议的无线技术,外网使用有线和无线相结合的方式,PC终端使用有线,移动终端使用无线网络,从而实现对家居网络节点的集中统一监测和控制管理。无线化、快速化、精简化是智能系统的发展要求。本文首先对嵌入式平台环境搭建及移植、zigbee无线通信技术相关概念进行介绍,然后在此基础上详细阐述了智能家庭网关与家具设备节点的设计与实现,结合智能家具无线网络节点的分布环境构建了嵌入式WEB服务器,通过网络使用者可以随时随地的对家居系统进行监控本文在传统技术应用的基础上,学习探索改进,精简协调器软硬件平台,设计网络速度更快的网络家居节点模块,通过分析ZigBee协议中Cluster-Tree和AODVjr算法的优缺点,提出一种基于Cluster-Tree+AODVjr的优化路由算法,此优化算法能够有效地减小路由跳数,缩短传输时延,减少网络中死亡节点的数量,提高数据传送的成功率,设计数据交换处理能力更好的嵌入式服务器等等一系列新技术手段,实现了整体系统的快速、高效、准确、灵敏、精简和成本低廉的预期目标。论文最后通过对系统整体和细节模块的分析测试验证,得出了较合理而且符合设计之初预想的结论,本系统具有现实意义和应用价值,当然,在细节的处理上发现了一些非人为的不足之处,还需进一步研究和探索
[Abstract]:With the national material and cultural level increasing, the spiritual quality needs to be improved. The rapid development of science and technology, the promotion of intelligent Internet of things upsurge, rapid pace of life. Some domestic and external factors, such as the Chinese type of market-oriented home demand, have greatly accelerated the emergence and development of smart home. Although the concept of smart home has been put forward for a long time, due to all kinds of fate. At present, it is not possible to keep pace with the times and meet the increasing living needs of the people. Therefore, it is of practical significance to study and design and optimize the smart home system. It can be said that the smart home system is the product of big data, Internet of things, human-computer interaction, artificial intelligence technology, but also human love for life, the pursuit of high-end atmosphere quality of life products of the times. This paper takes ARM9 as the core module of linux) as embedded operating system, and designs with temperature, humidity and illumination. A series of sensors, such as gas, combine the home node of zigbee network data transceiver module, and construct the network environment of WEB server gateway with embedded microprocessor as the core. Indoor use of a new generation of wireless protocol technology, the use of cable and wireless combination of the outside network to use cable PC terminal, mobile terminal uses wireless network. Thus, the centralized monitoring and control management of home network nodes can be realized. Wireless, fast and simplified are the development requirements of intelligent system. Firstly, this paper introduces the related concepts of wireless communication technology based on embedded platform setting and transplanting. Then, the design and implementation of the intelligent home gateway and furniture device node are described in detail, and the embedded WEB server is constructed based on the distributed environment of the intelligent furniture wireless network node. Through the network users can monitor the home system anytime, anywhere Based on the application of traditional technology, this paper studies the improvement, simplifies the hardware and software platform of the coordinator, and designs a faster network home node module. The advantages and disadvantages of Cluster-Tree and AODVjr algorithms in ZigBee protocol are analyzed. An optimized routing algorithm based on Cluster-Tree AODVjr is proposed, which can effectively reduce the number of routing hops, shorten the transmission delay and reduce the number of dead nodes in the network. Improving the success rate of data transmission, designing embedded server with better data exchange and processing ability, and so on, a series of new technical means have realized the whole system fast, efficient, accurate and sensitive. Streamlining and low-cost expectations. Finally, through the analysis and test of the whole system and the detail module, the conclusion that the system is reasonable and in line with the initial design is obtained. The system has practical significance and application value, of course. Some non-man-made deficiencies have been found in the handling of details, which need to be further studied and explored.
