【摘要】 智能家居是利用计算机技术、控制技术、图像显示技术以及通讯技术将各种家用设施通过家庭网络连接到一起,从而为人们提供更舒适更便捷的生活。传统的智能家居一般是通过有线线路的布线方式对家用设施进行控制和通讯的,但这样的有线方式不仅使人们很难脱离各种线缆的束缚、安装成本较高,而且系统的扩展性也很差。基于无线网络技术的智能家居不仅可以摆脱线缆的束缚、降低安装成本,而且系统的扩展性也有了大幅度的提高。所以研究无线智能家居对智能家居的发展是十分必要的。本文设计的智能家居系统实现了对家庭环境的检测和控制,组建了基于无线传感器网络技术的家庭网络。由于无线智能家居越来越多的倾向于低成本、低功耗、易操作、易安装的设计思路。所以本文以无线传感器网络为组网形式,使用TI公司推出的超低功耗单片机MSP430F449和低功耗无线收发芯片CC1100为核心设计一种智能家居系统。系统安装方便,适用范围广,具有很好的实用价值。论文在查阅大量相关资料的基础上,完成了智能家居系统中主控模块,传感器模块的软硬件设计。硬件设计方面,完成单片机的选型和各模块主要组成电路的功能、设计思想和硬件原理图。软件方面,通过分析各个模块的功能,完成流程图和程序的编写。此外,本文还详细介绍了一款低功耗无线收发芯片CC1100,并围绕CC1100完成了无线收发模块的软硬件设计。硬件方面,完成CC1100的外围电路设计和单片机的接口电路设计。软件方面,完成CC1100的寄存器设置和单片机间的SPI通讯以及数据发送和接收,并给出了流程图和部分程序。本文另一个重点是智能家居系统网络的设计。在比较现有组网的技术的基础上,选择采用无线传感器网络技术组建智能家居内部通讯网。通过比较几种基本的网络拓扑结构,采用星型网络拓扑结构。完成了无线传感器网络通讯协议的设计,着重介绍了CC1100的通讯协议和数据包格式化,并给出了无线传感器网络数据传输的流程图和部分程序。最后,对系统进行了调试,验证了系统设计的合理性,并对论文进行了总结,指出了系统设计的不足和改进思路,为课题的进一步研究做了准备。
【Abstract】 Smart home use computer technology、control technology、image display technology and communication technology to contact kinds of constructions with family network. Thus, smart home provides a more comfortable and more convenient life for people. Traditional smart home generally carries on control and communication with this measure that install wire line circuit. But this measure not only make people difficutly to separate from kinds of line、spend the cost of installation ,but also system’s extension is also very bad. hThe smart home based on wireless technology not only break away the line、reduce the cost of installation , moreover system’s extension also had the large scale enhancement. Therefore the research based on wireless that is very essential to the development of smart home.The smart home system that this article designs realize the home environment examination and the control, set up based on the wireless sensor networking family network. Because smart home more and more lean to low cost、low power、easy operation、easy installation design mentality. This article use the wireless sensor network as the network form and use low cost and low power singlechip MSP430F449 from TI company and low power and low cost RF-Transceiver to design a smart home. The system installation is convenient and the applicable scope is broad. The system has the very good use value. The paper completed software and hardware design of control module、the sensor module based on referring correlative information. Aspect of hardware design, completes selection of single chip and design of mostly circuit in each module and hardware schematic diagram. Aspect of software design, Through analyzes each module the function, completes the flow chart and the procedure.In addition, this article also introduced a low power wireless receiving and transmitting chip CC1100 in detail, completed software and hardware design of wireless receiving and transmitting module. Aspect of hardware design, completed the peripheral circuit design of CC1100 and design of interface circuit .Aspect of software design, completed setting of register、communication of SPI with single chip and receiving and transmitting of data, has given the flow chart and the procedure.This article another key point is network of smart home. Based on comparing existing network’s technology, selects wireless sensor network to establish family network. Through compared several kind of basic network topology, selects the star network topology. Completed communication protocol design of wireless sensor network, Introduced emphatically the CC1100 communication protocol and the data packet format, has given the wireless sensor network data transmission flow chart and the procedure.Finally, carried on the debugging to the system, confirmed rationality of the system design, summarized the paper, had pointed out system design’s insufficiency and the improvement mentality, have made the preparation for further research of the topic.
