A fast networking method for power line carrier communication

Abstract

The invention provides a rapid networking method for power line carrier communication and specific implementation steps thereof, and aims to solve the problems of low networking efficiency, complex network structure and poor reliability in a power line carrier communication system. Compared with a conventional networking way, the rapid networking method provided by the invention has the advantages that a node association process is synchronously performed in the processes of completing hierarchical management and forming a system route, and a node association table is formed, so that the communication reliability of the system is ensured while the networking efficiency is increased. The local reconstruction range of a network is small; the efficiency is high; and the self-healing ability is high. The rapid networking method is suitable for data communication of a power line carrier communication system.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a fast networking method applicable to but not limited to power line carrier communication. Background technique [0002] With the rapid development of the global economy, the expansion of the scale of power grid construction, the increasing requirements for the quality, safety and intelligence of power consumption, and driven by the awareness of energy conservation and environmental protection, the development and construction of smart grid has become a world-recognized development trend. As an important branch of smart grid communication technology, power line carrier communication (PLC) technology uses the existing widely distributed power distribution network as the transmission medium, which has the advantages of fast construction speed, wide coverage, low investment, and no need for rewiring. It is suitable for A variety of application services in the smart grid, s...

These relay networking methods have their own advantages and disadvantages. For example, the invention patent with the publication number CN103874291A and the name "Intelligent Networking Control System and Method Based on Power Line Carrier" has the publication number CN102075215A and the name is "A Power Line Carrier Communication The invention patent of "Automatic Relay Networking Method in China", the publication number is CN104022955A, and the invention patent named "A Method for Central Point Recruitment and Tree Cluster Network Routing and Networking Method", the publication number is CN103441781, and the name is " The invention patent and publication number of "Power Line Carrier Ad hoc Network Method and System" is CN103345836, and the invention patent named "Adhoc Network Meter Reading Method Based on Low Voltage Power Line Carrier" can be considered as a non-overlapping clustering method. Using these methods The network will get a tree-like network topology diagram, the network structure is clear, and the network efficiency is high, but the link is single and the invulnerability is poor. When a relay node in the distribution network fails, some The failure of the network, the nodes of this part of the failed network will lose connection without human intervention (re-network); and as described in "Research on Power Distribution Network Planning Based on Improved Ant Colony Algorithm" The swarm algorithm can avoid the prematurity of the traditional ant colony algorithm. Its connectivity and load balancing are better than other networking methods, but the network structure is complex and the system networking is inefficient, so it is more suitable for local network reconstruction.
