【摘要】：随着经济的发展，特别是近年来计算机技术、网络通信技术、自动化控制技术和传感器技术的突飞猛进，彻底改变了人们的生产和生活方式。人们对家居生活方式有了新的理念，在舒适性、便利性和安全性方面有了更高的要求。智能家居的蓬勃发展也由此拉开了序幕。它利用网络通信、嵌入式等技术使家庭设备网络化、自动化，同时能够与外部网络进行通信。智能家居的诞生提高了人们生活的舒适性、便利性和安全性。本文分析了现有智能家居控制系统的发展现状，研究了多种网络通信技术的特点，提出了一种可行的智能家居控制系统方案。并以LED灯控制为例做了详细设计。本文主要内容及创新如下： 1)本文在充分研究智能家居系统内部通信结构的基础上，对现有无线网络技术进行分析比较，，决定采用ZigBee技术作为智能家居系统内部网络的通信协议，并对ZigBee协议栈整体架构及各层功能作了应用研究，为下面的设计打下理论基础。 2)采用最新的ZigBee片上系统CC2530为核心处理器，完成了协调器和ZigBee传感器节点的硬件设计。除了核心处理模块外还包括电源、传感器、LED灯、按键、LCD显示、串口等功能模块，整个通信平台具有较大的灵活性和扩展性。 3)设计完成了由ARM嵌入式网关、ZigBee协调器、ZigBee传感器节点构成的智能家居控制系统，经由相关实验表明：该系统架构合理，工作稳定、可靠。 4)提出了一种新的传感器节点布置策略。把智能家居照明系统与控制系统有机结合在一起，不仅去除了传统传感器网络能量受限的弊端，而且降低了整个系统的成本、提高了控制网络的稳定性。
[Abstract]:With the development of economy, especially with the rapid development of computer technology, network communication technology, automatic control technology and sensor technology in recent years, Completely changed people's production and life style. People have a new concept of home life style, in comfort, Convenience and security have higher requirements. The vigorous development of smart home has also opened the prologue. It makes use of network communication, embedded technology and other technologies to make home equipment networked and automated. At the same time, it can communicate with the external network. The birth of smart home improves the comfort, convenience and security of people's life. This paper analyzes the development status of the existing intelligent home control system, and studies the characteristics of various network communication technologies. A feasible scheme of intelligent home control system is proposed, and the detailed design of LED lamp control is given. The main contents and innovations of this paper are as follows:. 1) on the basis of fully studying the internal communication structure of smart home system, this paper analyzes and compares the existing wireless network technology, and decides to adopt ZigBee technology as the communication protocol of intelligent home system internal network. The whole architecture of ZigBee protocol stack and the functions of each layer are studied in order to lay a theoretical foundation for the following design. 2) using the latest ZigBee on-chip system CC2530 as the core processor, the hardware design of the coordinator and the ZigBee sensor node is completed. Besides the core processing module, it also includes the function modules such as power supply, sensor LED lamp, keyboard LCD display, serial port and so on. The whole communication platform is flexible and extensible. 3) the intelligent home control system composed of ARM embedded gateway ZigBee coordinator and ZigBee sensor node is designed and completed. The experimental results show that the system is reasonable, stable and reliable. 4) A new sensor node arrangement strategy is proposed. The combination of intelligent home lighting system and control system not only eliminates the disadvantages of traditional sensor network energy limitation, but also reduces the cost of the whole system. The stability of the control network is improved.
