Broadband-based power line carrier station area identification method

Abstract

The invention discloses a broadband-based power line carrier station area identification method. The method comprises: establishing a broadband carrier communication network of real-time communicationin a low-voltage station area; sending an identification signal to extend the same to any corner of the station area, and carrying out station area ownership judgment; synchronizing all equipment inthe broadband carrier communication network to a shared clock NTB (Network Time Base); and carrying out zero crossing point detection to realize physical phase identification of receiver STA. The method can automatically identify a current station area in a crosstalk case on the basis of a broadband carrier of an OFDM modulation mode according to intensity of a signal and a characteristic parameter of a transformer, automatically selects a concentrator of the station area for network accessing, and has, on a technology aspect, capability to solve the station area crosstalk problem.

Description

technical field [0001] The invention relates to the technical field of station area identification, in particular to a method for identifying a station area based on broadband power line carrier. Background technique [0002] The relationship between household variables is the foundation of the marketing system. The confusion of household variable relationships will lead to incorrect data in the marketing system, making various tasks impossible to perform correctly (such as more refined line loss). Crosstalk between stations is one of the main reasons for the confusion of the relationship between households and transformers. [0003] The problem of crosstalk in the station area has always plagued the carrier communication scheme. Although due to the isolation effect of the transformer between the stations, the communication signal is greatly attenuated. Signals between stations still affect each other through parallel line crosstalk, ground wires, and space radiation. Esp...

Problems solved by technology

It is said that the identification time is about 1 month, and the success rate of identification in the station area is too low (60-70%), which is almost unusable
