基于物联网的智能家居系统设计与实现

Design and implementation of smart home system based on Internet of things

针对传统智能家居系统中各种通信技术之间互联的困扰,提出了一种智能家居网关的设计。以嵌入式处理器ARM Cortex-A8为核心,Linux为实时操作系统,采用Zigbee、短信、蓝牙、无线网络相结合的通信技术,以满足家庭远程监控和家电控制的个性化需求。在ARM Cortex-A8处理器上构建嵌入式http服务器,通过Zigbee实现家庭内部无线网络的建立,通过无线网络和短信实现外部对该系统的连接和控制。实验结果表明,该设计有效提高了家居控制的便利性和智能家居设备扩展方面的兼容性。

The traditional smart home systems are troubled by the interconnection between various communication technologies. A smart home gateway was designed to solve this problem. The gateway used ARM Cortex-A8 embedded processor as core, with Linux operating system. The gateway combined Zigbee, Short Message Service （SMS）, Bluetooth, wireless network and other communication technologies to meet the needs of home remote monitoring and controlling. Embedded HTI＇P server was built on the ARM Cortex-A8 processor. Smart home controllers was connected with each other by Zigbee wireless network. The system was controlled through wireless network and SMS module. Experimental results show that the design effectively improves the convenience of home control, improve the compatibility of the new smart home devices.
