Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] refer to Figure 1 to Figure 7 , a method for identifying the type of electrical grid load electrical appliances and counting the electricity of different electrical appliances, the method comprising the following steps:

[0051] 1) Sampling the high-voltage signal and high-current signal on the side of the grid bus;

[0052] 2) Convert the high-voltage signal collected in step 1) into the first voltage signal through a voltage transformer or a voltage Hall sensor, and compare the first voltage signal to detect the zero-crossing point of the signal to provide a time reference for subsequent signal analysis; The large current signal collected in step 1) is converted into a second voltage signal through a current transformer or a current Hall sensor, and the second voltage signal is subjected to follow-up isolation and program-c...

Abstract

The invention discloses a method and device for the recognition of power load and electric appliance types and the statistics of electric quantities of different electric appliances. The method comprises the steps: carrying out the sampling of a high-voltage signal and a large-current signal of one side of a power grid, carrying out the analysis of the employed data, recognizing an electric appliance in use in the power grid, monitoring the electric quantity of each type of electric appliance in real time, finding the electric appliance which wastes the electric energy according to the monitoring result, and taking the further measures to achieve the energy saving and emission reduction.

Description

technical field [0001] The invention relates to a method and a device for identifying the type of electrical network load electrical appliances and counting the electricity of different electrical appliances. Background technique [0002] With the increasing shortage of oil, electricity and other natural resources, the concepts of environmental protection and energy conservation are gradually being paid attention to. According to statistics, about 39% of the energy is used in the human living environment. Therefore, more and more buildings start to use smart meters (Smart Meter) with energy calculation and control capabilities to provide real-time Various electricity consumption information in the user's living environment. [0003] Generally speaking, in order to understand the actual power consumption of various electrical appliances or equipment in a building, the most direct way is to install measuring devices such as small electric meters on each electrical equipment. ...
