Abstract

The invention provides an optimization method of a high-speed power line carrier communication network, and belongs to the technical field of communication. The method comprises the following steps: collecting network topology information of a current transformer area, and generating a network topology structure diagram; analyzing the communication capability of each station; selecting a to-be-optimized site, and evaluating the communication capability quantification information of the to-be-optimized site to obtain an evaluation result; if the evaluation result meets the optimization condition, generating a candidate list; establishing a physical topological structure diagram; marking a site corresponding to each network equipment; selecting an optimal candidate proxy site from the candidate list based on the physical topological structure diagram as a new proxy site of the to-be-optimized site; traversing each site to obtain an optimized network topology structure diagram; analyzing the communication capability of each station based on the optimized network topology structure diagram; and when the communication capability optimization result meeting the optimization condition does not exist, issuing the optimized network topology structure diagram to all network nodes of the current transformer area through the CCO.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optimization method for a high-speed power line carrier communication network. Background technique [0002] High-speed power line carrier (HPLC for short), also known as broadband power line carrier, is a broadband power line carrier technology for data transmission on low-voltage power lines. HPLC mainly adopts Orthogonal Frequency Division Multiplexing (OFDM) technology, and the frequency band uses 2MHz-12MHz. Compared with traditional low-speed narrowband power line carrier technology, HPLC technology has large bandwidth and high transmission rate, which can meet the higher requirements of low-voltage power line carrier communication. demand. The HPLC communication network generally forms a central coordinator (Central Coordinator, CCO) as the center, and a proxy coordinator (Proxy Coordinator, PCO) (smart meter / type I collector communication unit, broadband carrier...
