Method and device for inhibiting interference signal and electricity consumption information collection system

Abstract

The invention provides a method, equipment and power consumption information collection system for suppressing interference signals of power consumption information, and relates to the technical field of power consumption information collection of power grids. The method includes: the isolation device obtains a carrier signal through a power line, the isolation device performs isolation processing on the carrier signal to obtain a first signal; the filtering device performs filtering processing on the first signal to obtain power consumption information; The filtering device outputs the power consumption information through the power line. The invention realizes the restraint of the interference signal in the power consumption information and improves the success rate of power consumption information collection by setting the isolation device and the filter device between the power consumption equipment of the power grid and the main station.

Description

technical field [0001] The present invention relates to the technical field of power grids, in particular to the collection technology of power consumption information of the power grid, specifically a method, equipment and power consumption information collection system for suppressing interference signals of power consumption information. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section.
