应用电力猫构建智能家居局域网

Construction of Intelligent Home Furnishing Local Area Network by Applying PLC Modem

可靠有效的通信媒介及通信技术是构建有效网络的必要条件,基于此构建智能家居局域网才能实现对家庭所有电器的统一控制管理及所有表计的采集。针对以太网技术具有极高的带宽(10 Mbps及100 Mbps等更高速率)和较好的兼容性的优点,提出将其应用于智能电器是智能化电器的发展方向。比较目前可供选择的局域网媒介,包括网线及其他通信线缆、无线信号、及使用载波技术的固有电源线,指出使用电力猫的载波方式比较理想,适合各种家庭,能便捷地为实现全家电器的管控和监测提供媒介,其电力载波采用正交频分复用方式进行调制,能够有效规避干扰。给出了网络构架方案及网络测试方法,并通过分析证明其具备高度的可推广性。

Construction of intelligent home furnishing local area network based on reliable and effective communication medi- um and technology which are necessary for constructing effective network can realize united control management for all elec- trical equipments and collection for all meters. Aiming at advantages of very high bandwidth （10 Mbps and 100 Mbps or higher speed rate） and better compatibility of Ethernet technology, this paper proposes that application of it in intelligent e- lectrical equipment is the development direction for intelligentized electrical equipment. It points out that it is desired to a- dopt carrier technology based on PLC modem which is suitable for various families and realizing management and control for all electrical equipments and providing medium for monitoring. By adopting orthogonal frequency division multiplexing for modulation, the power carrier can avoid interruption effectively. It presents network construction program and testing method and proves strong ability of generalization.
