G3-PLC技术在智能建筑中的应用

Application of G3-PLC Technology in Intelligent Building

考虑到家庭/建筑环境通讯使用的窄带载波技术在通讯中还存在一些瓶颈,例如噪声干扰、配电网结构等,本文提出了一种网络融合架构,通过基于以太网的网络集成来提高窄带电力通信线(PLC)G3-PLC技术的性能,同时分析了G3-PLC设备中实现的CSMA/CA协议的行为。通过TDMA方案解决了性能随着网络节点数量的增加而下降的问题,最终使网络性能得到了进一步的提高。

This paper, considering that the carrier module used in home/building environment communication basically adopts narrow-band carrier technology, and there occur some bottlenecks in the communication, such as noise interference, distribution network structure, etc., proposes a network fusion architecture, which improves the performance of narrow-band power communication line (PLC) G3-PLC technology through network integration with ethernet. At the same time, the paper analyzes the behavior of CSMA/CA protocol implemented in G3-PLC device, to solve the problem that the performance of the network decreases with the increase of the number of network nodes through the TDMA scheme, and finally the network performance is further improved.
