电力线载波自动抄表系统集中器的设计

文章针对我国低压电力线上存在的高衰减、高噪声、高变形,设计了一种基于电力线载波通信技术的远程自动抄表系统,该系统分为三部分,即上位机管理主站、集中器和载波电表。集中器是连接管理主站与载波电表之间的枢纽,起着上传下达的作用。文章重点研究设计了集中器硬件系统。此外,为保证系统的可靠传输,还引入了扩频技术以提高系统的抗干扰能力。

Design of Automatic Meter Reading System Concentrator on Power Line Carrier

This article design a power line carrier communication technology based on remote automatic meter reading system,in view of the existence high attenuation,high noise,high deformation on the low-voltage power line,and has three parts,the main station,concentrator and carrier meter.The concentrator connects the main station and carrier meter,is playing the important role.This paper focuses on the design of the hardware of concentrator.In addition,to ensure the reliable transmission system,and also introduced spread spectrum technology,in order to improve the system of anti-interference ability.
