Collector management electric energy meter phase sequence attribution system and device

Abstract

The invention discloses a collector management electric energy meter phase sequence attribution system and device. The system includes: a concentrator is connected to a collector, a collector is connected to a plurality of collectors to manage a phase sequence attribution device of an electric energy meter, and a plurality of collectors manage The phase sequence belonging device of the electric energy meter is connected with multiple electric energy meters in one-to-one correspondence; the collector determines the phase sequence of the power supply phase line where it is located according to the phase sequence of the concentrator, zero-crossing information and its own zero-crossing information; the collector manages the phase sequence of the electric energy meter The sequence belonging device is used to detect the zero-crossing information of the corresponding electric energy meter, and send the zero-crossing information to the collector through the communication module, so that the collector Determine the phase sequence of the power supply phase line where the energy meter is located. The invention solves the problem that the collector recognizes the phase sequence ownership of all electric energy meters hanging below by setting the collector to manage the phase sequence attribution device of the electric energy meter between the collector and the electric energy meter.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a collector management system and device for phase sequence assignment of electric energy meters. 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. [0003] Generally speaking, the ...

AI Technical Summary

Problems solved by technology

Collectors generally have multiple electric energy meters attached to them, and different electric energy meters may be connected to different power supply phase wires, and electric energy meters themselves do not have the phase sequence recognition function, so the collector cannot directly identify the phase sequence of the electric energy meters attached to them at present. ordinal attribution problem
