【摘要】 随着计算机网络的高速发展，计算机网络的作用已经不仅局限于办公或工业控制，而且开始进入人们的生活领域。学术界近年提出了“Bringing the Internetto Life”，即“把互联网带到生活中”的口号。在这种形势下，智能家居网络就成了目前网络发展的一个重要方向和必然结果。 智能家居网络的发展，导致大量的复杂的布线。线路问题是阻碍智能家居网络发展的关键。利用已有低压电力线进行组网是一种合理、有效、廉价的方法，并且在智能家居网络中表现出其特有的优势。 本文首先介绍了智能家居网络的构架、功能和发展趋势，然后对低压电力线传输特性进行详细分析。为了克服电力线通信中的各种噪声干扰和严重的线路衰减，必须选择合适的通信技术，设计出一套完善的滤波机制。在对目前流行的多种电力线通信方法进行了分析和比较基础上，根据智能家居网络通信特点，提出了基于扩频通信的智能家居网络电力线系统模型。最后还对通信系统进行仿真，分析比较了仿真结果。更多还原

【Abstract】 With the rapid development of computer networks, the application of computer network not only affects the fields of office automation and industry automation but also plays a role in the field of life, hi recent years, academe brings forward the slogan "Bring the Internet to life". In this situation, Intelligent Home Network (MM) has become an important direction and inevitable result of current network development.The development of IHN requires a large number of complex wiring and wiring has become a key work. The use of low voltage power line as a communication medium is reasonable, effective and low-costing. So it has advantages in IHN.At first the paper introduces the framework, function and developing trend of IHN, then analyzes the signal transmission characteristics in low voltage power line in detail. Based on the studying and comparing of some kinds of power line communication techniques and the communication characteristics of IHN, the paper designs a low voltage power line communication system using Spread Spectrum Communication(SSC) technique, and it also provides the simulation of communication system and analyzes its results.更多还原
