【摘要】：随着经济快速发展和科学技术水平不断提高,人们对生活品质的追求越来越高,嵌入式智能家居技术得到迅猛发展,研发出一套安全、便利、舒适、高效的智能家居系统成为各大智能家居公司的首要目标。计算机、互联网、嵌入式以及无线传感网络技术的发展和智能家居的市场需求以及发展前景不断促进智能家居技术发展。于是在全世界智能家居公司在智能家居领域的研究设计上出现了“百家争鸣”的景象,但是也出现了行业通信标准不统一、技术水平研究方案参差不齐等弊端,在一定程度上制约了智能家居行业的发展。本文在综合考虑整个系统的扩展性、可靠性、实用性、成本、功耗、体积等一系列的因素的基础上,使用嵌入式ARM与Linux、Zigbee无线网络通信、传感器、单片机、Qt图形应用界面等技术,提出了一套比较完整的嵌入式智能家居系统的解决方案,同时设计了相关电路模块、驱动程序和软件应用程序,验证了此设计方案的可行性。嵌入式智能家居系统由智能网关、Zigbee协调器、无线通信网络、Zigbee终端节点四部分组成,主要实现了以下几个功能：本地触摸屏或者PC机监控、室内温度获取、防盗报警、LED灯开关控制。为了满足人们日益增长的生活需求,住宅智能化技术将得到很大发展,嵌入式智能家居系统功能将会变得更加全面、更加强大,因此,本文设计阶段考虑的主要问题是设计和实现一套能满足当前人们生活需求且便于以后软硬件维护、扩展、升级的嵌入式智能家居系统。为了解决这个问题,本系统中的智能网关采用S5PV210处理器芯片为主控制器、U-Boot作为引导加载程序、嵌入式Linux作为内核、Qt图形界面作为应用程序软件。系统中的无线通信网络采用的是Zigbee无线星型网络拓扑结构和协议栈,协调器节点和终端节点则选用的是TI公司的CC2530芯片,以使整个系统网络可靠稳定运行,同时可以方便扩展系统功能模块和终端设备节点。最后设计软件程序对嵌入式智能家居系统的相关功能及其性能进行了测试。测试结果表明,系统能够稳定可靠地运行,实现了设计之前嵌入式智能家居系统功能需求,达到了前面已经设定的各项指标：易于扩展、低成本、低功耗、高性能、方便使用。
[Abstract]:With the rapid development of economy and the continuous improvement of science and technology, people are pursuing higher and higher quality of life. The embedded smart home technology has developed rapidly, and developed a set of safety, convenience and comfort. Efficient smart home systems have become the primary target of all smart home companies. The development of embedded and wireless sensor network technology and the market demand and prospect of smart home constantly promote the development of smart home technology. Therefore, smart home companies in the world in the field of smart home research and design. The scene of "a hundred schools of thought contending" appeared. However, there are also some drawbacks, such as industry communication standards are not uniform, technical level research programs are uneven, which restricts the development of smart home industry to a certain extent. On the basis of considering a series of factors such as expansibility, reliability, practicability, cost, power consumption and volume of the whole system, this paper uses embedded ARM to communicate with Linux Zigbee wireless network. In this paper, a complete solution of embedded smart home system is put forward, and the related circuit module, driver program and software application program are designed. The feasibility of the design is verified. The embedded smart home system is composed of intelligent gateway Zigbee coordinator and wireless communication network Zigbee terminal node. The main functions are as follows: local touch screen or PC monitor. Indoor temperature acquisition, anti-theft alarm LED lamp switch control. In order to meet the increasing needs of people, intelligent residential technology will be greatly developed, embedded smart home system functions will become more comprehensive, more powerful, so, The main problem in the design phase of this paper is to design and implement a set of embedded smart home system which can meet the needs of current people and be easy to maintain, expand and upgrade in the future. The intelligent gateway in this system uses S5PV210 processor chip as the main controller and U-Boot as the boot loading program. The embedded Linux is used as the kernel QT graphical interface as the application program software. The wireless communication network in the system adopts the Zigbee wireless star network topology structure and the protocol stack, the coordinator node and the terminal node choose the TI company's CC2530 chip. In order to make the whole system network run reliably and stably, the system function module and terminal equipment node can be expanded conveniently at the same time. Finally, the software program is designed to test the related functions and performance of the embedded smart home system. The test results show that the system can run stably and reliably, and achieve the functional requirements of the embedded smart home system before the design. Meet the previous set of indicators: easy to expand, low cost, low power, high performance, easy to use.
