摘要
针对ARM9微处理器在智能家居中的应用问题,设计了一种基于ARM9的电力载波信号在智能家居中的检测控制系统,其中以S3C2440微处理器芯片为核心,通过对传统方案CDMA的改进、系统的模块化处理以及Web服务器Boa的移植,同时利用OFDM在克服噪声和干扰等方面的优势,设计了OFDM控制检测电路,很好地解决了传统CDMA传输处理的局限性,使电力载波传输信号准确、高效到达各种控制设备,实现对智能家居的远程控制,实验仿真结果表明该系统结构简单,信号提取方便快捷,可移植性好,扩展能力强,可广泛应用基于物联网技术的智能家居控制系统。
Through the study of application problems of ARM9 embedded Microprocessor in the smart home, a design of smart home detection control system based on ARM9 embedded power line carrier communications was introduced in this paper. In above design, S3C2440 Microprocessor chip serves as the core. Moreover, through improvement of traditional project CDMA,modular processing of system and transplantation of web server Boa, meanwhile, taking advantages of OFDM overcoming the noise and interference, we develop a novel control and detection circuit of OFDM to solve the limitations of CDMA traditional information transmission and processing, which makes power line carrier transmission signal accurately and efficiently received by the control equipments leading to achieving the remote control of intelligent home furnishing. The actual research shows that the system exhibits the amazing advantages of simple structure, convenient signal extraction, good portability and strong scalability with wide applications in smart home control system based on internet technology.
