Novel PLC networking structure and method as well as corresponding novel intelligent electricity meter carrier module

Abstract

The invention discloses a novel PLC networking structure. The novel PLC networking structure comprises a concentrator, a concentrator carrier module, at least one novel intelligent electricity meter carrier module and at least one electricity meter network, wherein the concentrator carrier module is a CCO end connected with the concentrator via communication; the at least one novel intelligent electricity meter carrier module is respectively connected with the concentrator carrier module via communication; each novel intelligent electricity meter carrier module comprises an STA unit and a Sub-CCO unit which work in parallel; the at least one electricity meter network is correspondingly connected with each novel intelligent electricity meter carrier module; each electricity meter network comprises a plurality of common intelligent electricity meter single carrier modules and a plurality of intelligent electricity meters; each intelligent electricity meter is connected with each common intelligent electricity meter single carrier module via communication; and each common intelligent electricity meter single carrier module is provided with an STA function. The novel PLC networking structure disclosed by the invention has the advantages that more intelligent electricity meters are accessed by additionally mounting the novel intelligent electricity meter carrier module with the Sub-CCO working mode logic in case of using one CCO end.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a novel PLC (Power Line Communication) networking structure and method and a corresponding novel smart meter carrier module. Background technique [0002] At present, smart meters in the national grid have been popularized, and the concentrator carrier module responsible for transmitting the information of terminal meters (smart meters) and management terminals (concentrators) has also been used on a large scale. The current carrier module mostly uses narrowband technology, and the communication rate is relatively low at tens of Kbps, which cannot meet the increasing real-time communication needs of the State Grid. [0003] HomePlug GreenPhy (a broadband power carrier communication protocol standard) is a broadband communication protocol that has been widely used in the national grid. According to this agreement, in the power grid application, the local carrier module of the...

Problems solved by technology

[0005] To sum up, the existing power line communication (PLC) networking has limitations on the number of devices connected to the network, and it is necessary to propose a technology that can realize the connection of a large number of smart meters without increasing the number of CCO terminals of the concentrator. solution to simplify the software complexity and avoid the problem of multiple CCO terminals synchronizing with each other
