Design Of Broadband Power Line Communication Software Based On Multi-protocol

Powerline Communication(PLC)refers to a communication technology that uses powe r lines as transmission media to modulate information onto electrical signals for data trans mission.With the popularity of smart homes and smart grids,there will be a large numbe r of terminal devices waiting to access the network,and power line communication is bec oming an important solution for access networks because of its wide coverage,low cost,a nd easy maintenance.How to combine PLC technology with other related technologies and establish a power line communication network based on a configuration network is be coming a research hotspot.This paper uses the MiinePort and IT900 as the core module to design the power lin e carrier system based on the Ethernet interface,and realize the conversion between Ether net data and power line data.Using MiinePort as the host of the IT900,a communication node is formed by defining system parameters and user parameters,and a medium-low vol tage power line communication network is established on this basis.In order to facilitate t he management of the power line communication network,a dedicated management system has been designed to implement the equipment configuration,parameter management,and various power remote communication functions defined in the DL/T634.5104 transmission protocol.In addition,in order to expand the scope of use of the acquisition terminal in th e power system,this article also designed an ARM-based serial conversion board,which c an be applied to the carrier remote module to solve the GPRS-based concentrators in prac tical applications.This design is based on three protocols,TCP/IP protocol stack,GPRS c ommunication protocol and power line communication protocol.The core idea of the desig n is to realize data conversion between the three protocols.After testing and verification,the power line communication system designed in this paper meets the design requirements.Through the system,the power line network can be set up,accessed,and managed by various nodes.In addition,various telecontrol communication functions defined in the DL/T 634.5104 transmission protocol can be implemented through this system.
