Abstract

The invention discloses an electric energy meter reading method and device. The method comprises the following steps: according to the reading success rate and reading time length of each child node in the pre-stored reading white list, selecting the reading mode corresponding to the child node; All the child nodes being divided into two groups according to the different ways of reading, At that same time, the power data of the electric energy meters corresponding to the two groups of sub-nodes being respectively read and read in the channels corresponding to the different reading modes; Judging whether the electric power data of a group of sub-nodes corresponding to the electric energy meter has been copied and read; if the power data of the electric energy meter corresponding to any oneof the two groups of sub-nodes is read out, reading out the power data of the electric energy meter correspond to the remaining non-read sub-nodes in the other group by the reading mode correspondingto the group of the electric energy meters under the condition that the communication success rate satisfies a predetermined condition. The electric power data of the electric energy meter correspondsto the remaining non-read sub-nodes in the other group. By continuously optimizing the reading path, the invention reduces the reading time of the electric power data of the electric energy meter andimproves the success rate of the reading.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a method and device for reading and reading an electric energy meter. Background technique [0002] With the rapid development of urbanization, citizens' requirements for high-quality life are gradually increasing, and the rapid expansion of power grid scale and the large increase of metering equipment have become an inevitable trend in the development of power grids. An important symbol of power grid construction is the electricity consumption information collection system, which generally consists of concentrators, collectors, and energy meters. The concentrator is used to issue collection commands to the collector, and the collector is used to receive and record the electricity consumption of the electric energy meter, realize the collection of power data information, and upload the data to the concentrator. Due to the continuous improvement of the intell...
