Problems solved by technology

[0004] This kind of distributed home appliance intelligent monitoring system composed of a monitoring module for each household appliance and the Internet of Things has poor reliability and complex structure; are often incompatible with each other), and the data provided by the built-in monitoring module provided by the manufacturer is often inconsistent in standard and format, and the accuracy cannot be guaranteed, which is difficult to convince people; if the unified external monitoring module will significantly increase the system cost, especially in every It is obviously unrealistic and unscientific to configure a monitoring module on a small household appliance with low cost and low power consumption.

Embodiment 1

[0038] Such as figure 2 As shown in the figure, the 220V AC mains enters the user's home through the user's incoming line switch K1, and then connects to n different types of household appliances DQ 1 ~DQ n .

[0039] An intelligent lumped detection system for household appliances based on pattern recognition, comprising an AC voltage transformer VT, an AC current transformer CT, a primary processing unit PM and an advanced processing unit CM; the two ends of the primary coil of the AC voltage transformer VT Respectively connected to the home zero line N and the home live line L; the primary coil of the AC current transformer CT is connected in series with the home zero line N; the secondary coil of the AC voltage transformer VT is connected to the AC current transformer CT The secondary coil serves as the input of the primary processing unit PM; the primary processing unit PM is connected with the advanced processing unit CM through the Internet of Things. The primary pro...

Embodiment 2

[0041] According to the pattern recognition-based intelligent lumped detection system for household appliances described in Embodiment 1, the difference is that the primary processing unit PM includes a digital signal processing chip DSP. The digital signal processing chip DSP calculates and processes the sampling value of the incoming voltage / current, obtains the power information, timing information and characteristic spectrum of the household appliances in use, and then uses the pattern recognition algorithm to intelligently identify the category, model, Quantity and operating status, operating rules and other information.

Embodiment 3

[0043] According to the pattern recognition-based intelligent lumped detection system for household appliances described in Embodiment 1, the difference is that the advanced processing unit CM includes a storage unit, and the storage unit classifies and stores the data uploaded by the primary processing unit PM. According to the stored long-term historical data, the advanced processing unit CM analyzes and processes the data of different household appliances on a longer cycle scale, and further digs out the long-term operation rules and operating status of different household appliances of users (use frequency / efficiency / The long-term change law of load rate), and then infer the "health" status of home appliances, as well as in-depth information such as potential operating risks and failures; and further count the performance differences between different manufacturers and the same type of home appliances.

Abstract

The invention relates to a household appliance intelligent set total detection system based on pattern recognition and a working method thereof. The detection system comprises an AC voltage transformer VT, an AC current transformer CT, a primary processing unit PM and an advanced processing unit CM; two ends of a primary coil of the AC voltage transformer VT are respectively connected with a service entrance zero line and a service entrance fire wire; a primary coil of the AC current transformer CT is connected with the service entrance zero line or the service entrance fire wire; a secondary coil of the AC voltage transformer VT and a secondary coil of the AC current transformer CT are taken as input ends of the primary processing unit PM, and the primary processing unit PM is connected with the advanced processing unit CM through an Internet of Things. The household appliance intelligent detection system based on the pattern recognition is the intelligent set total detection system, only samples a voltage and a current at a position of the service entrance lines, and does not need to sample a voltage and a current of each household appliance; and system hardware cost is reduced, the Internet of Things topological structure is simplified, and sampling data objectivity is improved.

Description

Technical field: [0001] The invention relates to an intelligent lumped detection system for household appliances based on pattern recognition and a working method thereof, belonging to the technical field of pattern recognition technology application. Background technique: [0002] With the rapid development of science and technology, there are more and more types and functions of household appliances, which are greatly changing the lives of modern people. Undoubtedly, the importance of home appliances to family life is getting higher and higher, and the technical complexity is also getting higher and higher, resulting in ordinary consumers getting less and less understanding of the technical principles of home appliances, and thus have a better understanding of different types of home appliances. The monitoring, analysis, and fault diagnosis and prediction of electrical appliances are becoming more and more important. [0003] In the prior art, the utility power enters thr...
