【摘要】 现在的中国正迎来一个”数字城市”、”数字社区”建设与“低碳经济”发展的热潮,3G技术和物联网应用对智能家居的发展也起到很重要的推动作用,而智能家居能够有效实现“低碳经济、绿色经济”。基于无线传感器网络的智能家居系统,将有效解决普通无线产品面临的诸多问题。用户所安装的各产品设备根据实际安装情况组成具有安全保证的传输网络,保证了系统智能操作的正确性、检测上报数据和用户控制下行数据传输的有效性。有效实现多设备的协同处理及准确判断能力。本论文利用切合家庭应用场景的自组网协议,利用众多的传输设备,配合涵盖面极广的检测手段,结合移动网络和现场图像,设计了一种基于无线传感网的智能家居检测系统。论文首先详细介绍课题的研究背景和国内外研究的现状,阐述了选题的意义。其次概况介绍了无线智能家居系统的系统架构与系统硬件平台,提出了检测设备、传输设备和网关设备的总体设计方案。第三,重点介绍了整个系统协议设计的原则、拓扑结构、协议解释、Frame结构、各网络层的数据结构以及接口函数。确定系统应采用分层的网络协议、竞争的数据发送方式、自动更换频点、自动分配地址的四跳拓扑结构,实现检测上报数据和用户控制下行数据传输的有效性。第四,重点介绍了无线智能家居系统应用层的网关软件设计,包括用户交互层,逻辑判断层和物理功能模块层,介绍了SmartHouseUI, SmartHouseAPP, LibSinkControl, GsmGprsCom, Libcamera,各模块的设计以及数据接口。系统软件设计遵循接口明晰、组合灵活、扩展性强的准则,具有非常强的扩展功能。第五,对这个系统协议软件从功能测试、容错能力测试、性能测试三方面进行了全面测试与分析,并给出了网关上位机软件的九大界面图集,同时从功能测试(传感器组网功能、网络拓扑更新功能、用户查询功能、用户手机控制网关功能)、稳定性测试(系统稳定工作的能力)、可靠性测试(系统电磁辐射的抗干扰能力)、健壮性测试(无线传感器网络的抗变化性)几方面对整个系统进行了联调。结果表明该系统在检测信息采集与智能控制方面有较高的准确性和可靠性,具有较强的应用价值。最后,对所做的工作进行了总结并对日后该系统的发展提出了更加有利的想法与展望。更多还原

【Abstract】 Nowadays, China is encountering a hot tide that waves the construction of "digital city", "digital community "and the development of "low-carbon economy". The applications of 3G technology and WSN (Wireless Sensor Network) also play a very important role in promoting the development of smart house which can effectively achieve "low-carbon economy, green economy." The smart house system based on WSN will effectively solve many problems that ordinary wireless products are facing. According to the actual condition of installation, all sorts of equipments installed by users make up the transmission networks that have been guaranteed for their safty, correctness of the smart system operation and effectiveness of detecting uploaded data and the downstream data transmission controlled by users, achieving the capability of collaborative processing and accurate judgement of multiple equipments.This paper designs a detecting system based on WSN, which makes use of many transmission equipments, combines with the widely-covered detecting means, mobile network and on-spot images.Firstly, the paper introduces the background and current researching progress of wireless sensor network at house and abroad and states the significance of the subject. Secondly, the system configuration and platform of system hardware are introduced, and the whole designing scheme of the detection, transmission and gateway equipments is put forward. Thirdly, the paper focuses on introducing the principle of the whole system protocol design, the structure of topology and frame, the explanation of protocol, the data structure of each network layer and interface functions, determining that system should adopt a network protocol with several layers, competitive data sending mode, four-jump topology structure that can automatically replace frequency points and assign addresses to achieve the effectiveness of detecting uploaded data and the downstream data transmission controlled by users.Fourthly, the paper mainly introduces the gateway software design of application layer in smart house system, including the interactive layer for users, the layer for logic judgement and the layer for physical function block.And the SmartHouseUI. SmartHouseAPP. LibSinkControl. GsmGprsCom. Libcamera. the design of each block and data interface are also mentioned. The design of system software follows the rules that the system should has clarified interface, flexible combination and strong expansibility. Fifthly, the system protocol software has been completely tested and analyzed in three aspects of the function test, the tolerance test and the performance test. and nine interface graphs of the gateway embedded software were given, meantime the system has been jointly debugged from the test of function, performance, reliability and robustness, such as the sensor network function, the topology updating function, the user’s query function, the user mobile phone control gateway function, the stable working ability of system, the electromagnetism radiation anti-interference ability of system, the wireless sensor networks anti variability. The results indicate that the system has show high accuracy and reliability in detecting the collection of information, and also has strong application value. Finally, the summary is made with respect to the work done and more favorable ideas and expectations are put forward with respect to the development of the system in future.更多还原
