Description

Technical Field

[0001] The invention relates to the field of electric energy meters, and in particular to an overall information detection and alarm system for electric energy meters. Background Art

[0002] The energy meter is an instrument for measuring energy consumption. In actual use, due to the fluctuation of parameters such as voltage and current of the power grid, as well as the error of the energy meter itself, the reading of the energy meter is not completely consistent with the actual energy consumption. As long as each energy meter is powered on, it will consume energy. This loss is theoretically a fixed value and will not increase with the increase of electricity consumption. Although the meter itself will not measure this loss. The total meter will measure the loss of the sub-meter. Generally, the loss of the meter itself is one to two degrees per month. Because it only loses one to two degrees per month, the power is quite small, and the accuracy that can be achieved by the household energy meter cannot be measured. The energy meter's own loss is mainly the loss of the voltage coil. Taking the voltage coil of a 220V single-phase energy meter as an example, the power loss is about 1W, so it is correct to add one degree of electricity to the reading of the energy meter every month for a single-phase energy meter. If it is a three-phase four-wire energy meter, because it has three voltage coils, the loss is about 3W. Summary of the invention

[0003] In order to solve the above technical problems in the prior art, the present invention provides an overall information detection and alarm system for an electric energy meter, which can identify each table body constituent pixel point in a combined processing picture corresponding to the table body of the electric energy meter as a whole based on a set brightness value distribution interval corresponding to the table body of the electric energy meter, perform fitting processing of multiple table body constituent pixel points after removing isolated table body constituent pixel points on each table body constituent pixel point to obtain a table body imaging area, perform edge pixel point judgment based on pixel value gradient on each constituent pixel point of the table body imaging area to obtain multiple edge pixel points in the table body imaging area, and determine a smoothness value corresponding to the table body imaging area based on the percentage of the cumulative number of multiple edge pixel points in the table body imaging area to the total number of pixel points in the table body imaging area, and the determined smoothness value corresponding to the table body imaging area is inversely correlated with the percentage of the cumulative number of multiple edge pixel points in the table body imaging area to the total number of pixel points in the table body imaging area, thereby completing intelligent judgment on the uniform distribution state of on-site materials in the table body imaging area.

[0004] According to the present invention, there is provided an overall information detection and alarm system for an electric energy meter, the system comprising: A rotation drive device, used to perform a time-sharing rotation operation on the electric energy meter in the factory state, so as to rotate the electric energy meter to different angles at evenly spaced moments and the difference between the two angles corresponding to every two adjacent moments is equal; A visual recording device connected to the rotation driving device, used for visually collecting different images of the electric energy meter at evenly spaced moments, so as to obtain various collected images corresponding to evenly spaced moments; A content combination device, connected to the visual recording device, for performing splicing processing on each received captured image to obtain a combined processed image; A meter body recognition device, connected to the content combination device, is used to recognize each meter body constituting pixel point in the received combination processing picture based on the set brightness value distribution interval corresponding to the meter body of the electric energy meter, and perform fitting processing on each meter body constituting pixel point after removing isolated meter body constituting pixel points to obtain a meter body imaging area; A first analysis mechanism, connected to the watch body recognition device, is used to perform edge pixel point judgment based on pixel value gradient on each pixel point of the watch body imaging area received, so as to obtain a plurality of edge pixel points in the watch body imaging area; a second parsing mechanism, connected to the first parsing mechanism, for determining a smoothness value corresponding to the body imaging region based on a percentage of the cumulative number of edge pixels in the body imaging region to the total number of pixels in the body imaging region, wherein the determined smoothness value corresponding to the body imaging region is inversely correlated with the percentage of the cumulative number of edge pixels in the body imaging region to the total number of pixels in the body imaging region; An alarm execution mechanism, connected to the second analysis mechanism, is used to send a signal of uneven material of the entire watch body when the received smoothness value corresponding to the imaging area of ​​the watch body is lower than or equal to a set smoothness threshold; Wherein, the alarm execution mechanism is also used to send a signal of uniform material of the entire watch body when the received smoothness value corresponding to the imaging area of ​​the watch body is higher than the set smoothness threshold; Among them, the rotation drive device is used to perform a time-sharing rotation operation on the electric energy meter in the factory state, so as to rotate the electric energy meter to different angles at evenly spaced moments and the difference between the two angles corresponding to every two adjacent moments is equal, including: the electric energy meter rotates around the centroid of the electric energy meter.

[0005] It can be seen that the present invention mainly has the following significant technical effects: Firstly: based on the set brightness value distribution interval corresponding to the meter body of the electric energy meter, each meter body constituting pixel point in the combined processing picture corresponding to the meter body of the electric energy meter is identified, and a fitting process of multiple meter body constituting pixel points after removing isolated meter body constituting pixel points is performed on each meter body constituting pixel point to obtain a meter body imaging area; Secondly: for each pixel point constituting the surface body imaging area in the surface body imaging area, edge pixel point judgment based on pixel value gradient is performed on each pixel point constituting the surface body imaging area to obtain a plurality of edge pixel points in the surface body imaging area; Again: the smoothness value corresponding to the surface body imaging area is determined based on the percentage of the cumulative number of multiple edge pixel points in the surface body imaging area to the total number of pixel points in the surface body imaging area, and the determined smoothness value corresponding to the surface body imaging area is inversely correlated with the percentage of the cumulative number of multiple edge pixel points in the surface body imaging area to the total number of pixel points in the surface body imaging area, thereby completing the intelligent judgment of the uniform distribution state of the on-site material in the surface body imaging area.

[0006] The overall information detection and alarm system for electric energy meters of the present invention is intelligently designed and has certain pertinence. Since the body imaging area corresponding to the entire body of the electric energy meter can be identified based on the set brightness value distribution interval corresponding to the body of the electric energy meter, a pertinent visual recognition mechanism is used to determine the smoothness value corresponding to the body imaging area, thereby completing the intelligent judgment of the uniform distribution state of the on-site materials in the body imaging area.
