摘要
由于电力线信道的时变性,电力线网络拓扑结构也复杂多样,使得电力线载波自动抄表系统的可靠性受到影响,因此有必要对电力线网络拓扑结构进行分析。对于变化的网络拓扑结构,采用中继路由自动抄表是提高可靠性的有效途径,具有自适应的网络协议能够使电力线通信的实用性大大提高。
Due to time-variation feature of power line channel, the topological structure is complicated and changeable, which affects the reliability of power line meter reading system. Therefore, it is necessary to analyze the topological structure of power line communication network. For dynamic network topological structure, automatic meter reading with Repeaters is an effective approach to improve the reliability, and a network protocol with good adaptive capability will greatly promote the practicability of power line communication.
