Low-voltage power line communication network constructing method for power meter reading system

Abstract

The invention discloses a low-voltage power line communication network constructing method for a power meter reading system. A constructed low-voltage power line communication network comprises a concentrator, a carrier power meter and a collector; wherein the collector and the carrier power meter are used as terminals for each level; the low-voltage power line communication network construction is completed in three steps: logical layering, communication topology construction and communication routing selection; the logical layering comprises establishing logical layers according to the length of the electrical distance between the terminals in each level, and respectively marking and attributing the collector and the carrier power meter into different levels; and the communication topology construction comprises storing the IP of the two terminals and the electrical distance into the concentrator under the condition that the electrical distance of the two terminals between the upper level and the lower level is less than or equal to L, thereby optimizing the network topology. In addition, the invention adopts a communication routing reconstruction method for the carrier power meter with failure, thereby realizing the timely updating and troubleshooting of the network topology.

Description

technical field [0001] The invention relates to a low-voltage power line communication networking method, in particular to a low-voltage power line communication networking method used in a power meter reading system.
