Power monitoring device capable of identify state of electric appliance and power monitoring method thereof

Abstract

The invention relates to a power monitoring device capable of identify a state of an electric appliance and a power monitoring method thereof, with a user participating and feeding back. The power monitoring device comprises a measuring module, a change detection unit, a searching module and am electric appliance feature database established based on participation and feedback of the user. When a change of power consumption characteristic is detected by the measuring module, the change detection unit and the searching module searches the electric appliance feature database according to the change to obtain the electric appliance having the similar change and state of the electric appliance. The user can participate in establishment of the electric appliance feature database through confirming a search result or choosing a correct electric appliance and the state of the electric appliance. When the user confirms the search result, the power monitoring device generates a corresponding relation of the electric appliance and the electric appliance feature database, and updates the electric appliance feature database, according to the change detection unit, the searching module, and information confirmed by the user.

Description

technical field [0001] The present invention relates to a power measurement and monitoring technology, and in particular to a power monitoring technology based on user participation and feedback data to identify the state of electrical appliances, so that users can easily judge the cause of power consumption. Background technique [0002] A power monitoring device (commonly known as an electric meter) is an instrument used to measure and monitor power consumption. It can be used to measure power consumption in residential, industrial and commercial areas or electrical appliances. Power companies can use the power consumption information displayed on the meter as the basis for selling power, and users can also install meters in homes or businesses at the main power source or the power source under test to monitor their power consumption. [0003] Environmental issues such as energy conservation and emission reduction are gradually being valued in the society, and most of the ...

AI Technical Summary

Problems solved by technology

[0004] Taking household electricity as an example, the smart meter in the past is usually installed at the main power supply of the home. Therefore, the user can only monitor the main power supply to obtain the power consumption of the main power supply in the home, but cannot judge the details of each electrical appliance in the home. Even if the smart meter adds Nonintrusive Load Monitoring (NILM) technology to identify electrical appliances based on their power consumption characteristic data, there will be a wide variety of electrical appliances and new ones will continue to be introduced. , it is difficult to collect electrical power consumption characteristic data, and it is impossible to accurately detect various electrical appliances

Moreover, it is also impossible to compare the power consumption of the same electrical appliance or different electrical appliances with the same function, used in different locations, so as to understand the efficiency of electrical appliances and determine the cause of power consumption

It makes it difficult for smart meters to help users understand the power usage and distribution of various electrical appliances in the home, and it is impossible to manage power-consuming appliances in the home and interpret the causes of power consumption, which makes it very difficult to plan power-saving plans

[0005] If the user wants to monitor the power consumption and usage of each electrical appliance in the home, and then judge the cause of the power consumption, the previous power monitoring technology is to install a power consumption monitoring device or sensor similar to a smart meter on each power socket in the home. It is impossible to use a single smart meter to monitor the total power supply in the home and the power consumption of each appliance

Due to the high installation cost of the above-mentioned power monitoring technology, consumers will reduce their willingness to use it
