物联网平台下基于云计算的智能家居系统设计

Smart Home System Design Based on Cloud Computing on Internet of Things Platform

物联网平台下采用云计算进行智能家居系统设计,提高家居控制的可靠性和智能性。传统的智能家居系统设计采用并行计算的Zig Bee技术,由于采用单线程驱动方式导致智能家居控制的指令容易出现中断。在物联网平台下,提出一种基于云计算和Android客户端的智能家居系统设计方法。首先进行了智能家居系统的总体设计,然后基于云计算方法进行智能家居控制的控制指令融合处理,在物联网平台下进行智能家居系统的模块化硬件设计,构建2个并行输入/输出外围接口单元PPI,设计DMA控制器和2个"看门狗"定时器,从而在物联网平台下实现智能家居控制的无缝连接和远程控制。实验测试结果表明,该智能家居系统的控制收敛性,系统稳定性和面向对象性较好。

In the Internet of things, cloud computing is used to design smart home system, improve thereliability and intelligence of home control. The traditional smart home system design uses the ZigBeetechnology of parallel computing, because the use of a single thread drive way to lead to the smart homecontrol instructions easy to interrupt. In the Internet of things, a smart home system design method basedon cloud computing and Android is proposed. First, the overall design of the smart home system, andthen based on the cloud computing method for intelligent home control instruction fusion processing, inthe Internet of things platform for smart home system modular hardware design, build 2 parallel input /output peripheral interface unit PPI, design DMA controller and 2 ＂watchdog＂ timer, so as to realize theintelligent home control of seamless connection and remote control. The experimental results show thatthe intelligent home system has better control convergence, system stability and object-oriented.
