Embodiment 1

[0046] In order to solve some shortcomings of intrusion, existing researchers have proposed non-intrusive load identification, but at present, only the data collected by smart meters are used to identify electrical appliances, and the accuracy of electrical appliance identification methods is not high enough. Not good enough.

[0047] At present, the charging of most electric vehicles is more based on the structure and specific electric vehicle models for charging identification. This method needs to be purchased separately to realize electric vehicle charging detection, and does not target the characteristics of the electricity generated during the charging process of electric vehicles. For identification and warning methods. Since the electricity characteristic recognition is directly built into the smart meter, it does not need to purchase additional detection components separately, because products such as the meter itself are also necessary products for every household, a...

Embodiment 2

[0078] Embodiment 2 discloses an electronic device, which includes a processor, a memory, and a program, wherein one or more processors and memories can be used, and the program is stored in the memory and configured to be executed by the processor, When the processor executes the program, the smart meter-based electric vehicle charging identification method of Embodiment 1 is realized. The electronic device may be a series of electronic devices such as a mobile phone, a computer, and a tablet computer.

Embodiment 3

[0080] Embodiment 3 discloses a computer-readable storage medium, which is used to store a program, and when the program is executed by a processor, the smart meter-based electric vehicle charging identification method of Embodiment 1 is implemented.

Abstract

The invention discloses an electric vehicle charging recognition method based on an intelligent electric meter. The method comprises the following steps: obtaining electrical parameters required by electric appliance recognition; converting the acquired single-channel current waveform data into a multi-channel to-be-separated characteristic matrix; decomposing the to-be-separated characteristic matrix into characteristic matrixes of a plurality of independent electric appliances by adopting a blind source separation algorithm; and judging whether the power consumption behavior of the electricvehicle exists or not according to the feature matrixes in all the independent electric appliances, If yes, sending alarm information. The invention further provides electronic equipment and a computer readable storage medium. According to the electric vehicle charging recognition method based on the intelligent electric meter, waveform data generated by all electric appliances in the power utilization process are collected through the intelligent electric meter, all the waveform data are analyzed to judge whether an electric vehicle is currently charged or not, and therefore electric vehiclecharging recognition is achieved; according to the method, the electric appliance recognition cost and the implementation difficulty can be reduced, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric meters, in particular to a method and device for identifying charging of an electric vehicle based on a smart electric meter. Background technique [0002] At present, for some vicious loads and restricted electrical appliances, it is necessary to identify them through a series of data collected by the meter, so as to ensure the safety of electricity consumption. Today, with the rapid development of smart grids, the identification of electrical appliances is also conducive to monitoring the electricity consumption of electrical appliances, and can make targeted strategies for saving electricity. The traditional identification of electrical appliances is an intrusive load monitoring. Sensors are installed on each electrical equipment of the user to collect data on its usage. The advantage of this method is that the monitoring data is accurate and reliable, but the disadvantages are high economic ...
