Embodiment 1

[0042] A non-intrusive load intelligent identification system for houses based on edge computing, see figure 1 , including smart devices installed on the load line of the house;

[0043] The smart device includes a housing 1 and an acquisition module, a processing module and a communication module arranged in the housing 1;

[0044] The acquisition module is used to follow a preset sampling interval Collect the electrical quantity data on the house-entry load line, and transmit the electrical quantity data to the processing module;

[0045] Specifically, the house entrance load line is the house entrance, see figure 2 , figure 2 Point A in the middle is the entrance of the house, and the smart device is the monitoring point of the house's household load.

[0046] The processing module is used to perform mutation detection on the electrical quantity data, and identify the equipment type of the equipment corresponding to the electrical quantity data according to the resul...

Embodiment 2

[0075] The second embodiment defines the processing flow of the processing module on the basis of the first embodiment.

[0076] The processing module is specifically used for:

[0077] S1: According to the collected historical electrical quantity data of each equipment, construct the load characteristic database of each equipment; specifically include: extracting the characteristic quantity in the historical electrical quantity data of each equipment respectively, and construct the load characteristic database of each equipment;

[0078] Among them, the category of characteristic quantities in the load characteristic database includes one or a combination of several of the following: rated active power, rated reactive power, fundamental current effective value and current total harmonic distortion.

[0079] Specifically, assume that the historical electrical quantity data sequence of a device is T={T 1 ,T 2 ,...,T N}, where N is the data length, T i (1≤i≤N) is the i-th hi...

Abstract

The invention provides a house non-intrusive load intelligent identification system based on edge calculation, which belongs to the technical field of power systems and comprises an intelligent device installed on a house-entry load line, wherein the intelligent device comprises a shell, and an acquisition module, a processing module and a communication module which are arranged in the shell; the acquisition module is used for acquiring electrical quantity data on the house-entry load line according to a preset sampling interval and transmitting the electrical quantity data to the processing module; the processing module is used for performing mutation detection on the electrical quantity data and identifying the equipment type of the equipment corresponding to the electrical quantity data according to a mutation detection result; and the communication module is used for realizing communication between the processing module and an external network. The external network is also used for realizing communication between the house non-intrusive load intelligent identification system and an external server or an external terminal. According to the system, cost is reduced, and timeliness of troubleshooting is improved.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a non-intrusive load intelligent identification system for buildings based on edge computing. Background technique [0002] Residential electricity consumption accounts for an important part of the electricity consumption of the whole society. However, the safety problems of residential electricity consumption occur frequently, and the use of illegal equipment is repeatedly banned, which is an urgent problem to be solved in the safe use of electricity in society. Among them, the safety of residents' electricity use caused by the use of illegal equipment is the main reason for the safety of residents' electricity use. It is of great practical significance to identify residents' illegal equipment in a timely and effective manner. [0003] In the past, the investigation and control of illegal equipment mainly relied on manual unannounced inspections, or transmitted...
