Method for improving data acquisition efficiency of low voltage power line broadband carrier waves

Abstract

A method for improving the data acquisition efficiency of low voltage power line broadband carrier waves comprises the following steps: in a system constructed by a concentrator, acquirers and electric energy meters, the concentrator is in communication connection with the acquirers and the electric energy meters respectively and executes the steps of physical relation construction, concurrent acquisition and acquirer traversal; data acquisition is carried out by adopting a traditional data acquisition scheme when a physical topology relation table is not established; and after the physical topology relation table is established, the electric energy meters connected with different acquirers simultaneously execute a concurrent meter reading treatment technology and an asynchronous communication technology in order to make the concentrator simultaneously acquire data of the electric energy meters externally connected with N acquirers in a same zone area. The method for improving the data acquisition efficiency of low voltage power line broadband carrier waves has the concurrent meter reading treatment technology and the asynchronous communication technology and adopts a scheme for simultaneous parallel acquisition of the electric energy meter data by the different acquirers to substitute a traditional scheme for acquiring one by one according to the sequence of the electric energy meters, so the data acquisition efficiency is substantially improved.

Description

technical field [0001] The invention relates to a method for improving the efficiency of low-voltage power line broadband carrier data acquisition, in particular to a method for solving the problem of fast acquisition of large service data in low-voltage power line broadband carrier large station areas, and belongs to the technical field of automatic meter reading in electric power systems. Background technique [0002] As the construction of the State Grid Corporation's electricity information collection system enters the leading and upgrading stage, the requirements for data volume and data frequency of various professions are increasing day by day. It is difficult to use the traditional low-voltage power line narrowband carrier for data collection to meet the increasing business needs, especially the number of users. In areas with a large amount of business data, it is difficult to guarantee the success rate of data collection, and it is difficult to meet the construction ...
