Smart meter, electrical appliance identification method and smart apartment system with the meter

Abstract

The present invention discloses an intelligent electric meter, an electric appliance identification method and an intelligent apartment system having an intelligent electric meter. The problem can besolved that which electric appliance in an operating state cannot be identified. The technical scheme of the method comprises the steps of: performing sampling of a current or a voltage in a power grid and processing data obtained through sampling to form sampling data information; performing preprocessing according to the sampling data information to remain information of sampling data which having values being larger than a preset reference value in the sampling data information to form pre-processing data information; extracting corresponding data information in the preprocessing data information based on the preprocessing data information and according to preset frequency points to form actual spectrum feature vectors; and performing comparing of pre-stored reference spectrum feature vectors of corresponding electrical equipment and the actual spectrum feature vectors, and identifying the corresponding electrical equipment based on the correlation coefficient comparison method. Theintelligent apartment system having the intelligent electric meter can achieve identification of an operating electric appliance and can record residents' electricity habits, and therefore, it is convenient for workers to analyze.

Description

technical field [0001] The invention relates to an electric meter, in particular to an intelligent electric meter, an electrical appliance identification method and an intelligent apartment system with the electric meter. Background technique [0002] Scientific use of electricity requires not only "safe" use of electricity, but also "reasonable and economical" use of electricity. Therefore, in order to use electricity scientifically, it is required that both industrial enterprises and ordinary residents should follow the principles of safety, economy, and rationality when using electricity; among them, safe electricity use is the first premise of scientific electricity use, and saving electricity is a scientific principle. The purpose of using electricity is that rational use of electricity is the way to achieve scientific use of electricity. [0003] In daily life, users often question their electric meters running too fast, and complain to the electric power department. ...

AI Technical Summary

Problems solved by technology

All these parameters cannot accurately describe the frequency domain characteristics of a fixed electrical load equipment, and cannot realize the identification of load electrical equipment

[0005] Based on the existing single-phase electric meter, the staff cannot intuitively explain and analyze the electricity consumption data of the corresponding electrical equipment to the user, so many users cannot understand it, which causes friction in communication and troubles the staff, so it has certain advantages. room for improvement
