Problems solved by technology

With the development of high-tech and network-based electricity theft, electricity theft that modifies and destroys the metering method occurs from time to time. Inconsistency, but at present, power companies often face the problem of difficult evidence collection when discovering the stealing behavior, which is not conducive to the processing of the stealing behavior and the recovery of electricity bills in the later stage

Embodiment

[0050] Example: such as Figure 1 to Figure 3 Shown; A method for judging the consistency of metering equipment based on graphic recognition, which includes:

[0051] S1: Collect images of different parts of the electricity meter submitted for inspection through an industrial microscope;

[0052] S2: Send the images of different parts of the electricity meter submitted for inspection to the judgment system for image processing; obtain the binarized image and the characteristic signals of the images of different parts of the electricity meter submitted for inspection and store them in the database as the batch of electricity meters submitted for inspection. Standard characteristic signal;

[0053] S3: Obtain the characteristic signals of images of different parts of the electricity meters delivered in the same batch as the electricity meters submitted for inspection or the on-site electricity meters;

[0054] S4: Compare the characteristic signal of the delivered electric met...

Embodiment 2

[0066] like figure 2 As shown, it is a flow chart of judging whether the electric meter of arrival is consistent with the electric meter sent for inspection for the present invention, including the following steps:

[0067] S10: After the same batch of electric meters from the same manufacturer arrives, it is necessary to perform sampling inspection on the arrived electric meters, and the method for obtaining the characteristic signal of the image of the electric meter arrived is as described in Embodiment 1;

[0068] S11: After obtaining the characteristic signal of the image of the electricity meter, it is necessary to determine whether the characteristic signal is a text signal;

[0069] S12: If the characteristic signal is a text signal, such as meter manufacturer, meter supply batch number, meter model, voltage, current, etc., then compare the characteristic signal with the standard characteristic signal to obtain the similarity, if the similarity is not 100 % will send...

Embodiment 3

[0072] like image 3 As shown, it is a flow chart of judging whether the field meter of the present invention is consistent with the electric meter sent for inspection, including the following steps:

[0073] S10: Carry out sampling inspection on the same batch of on-site ammeters from the same manufacturer, and the method of obtaining the characteristic signal of the on-site ammeter image is as described in embodiment 1;

[0074] S11: Calculate the similarity of the image characteristic signal of the on-site electric meter, and then judge whether the on-site electric meter or the electric meter submitted for inspection is the same electric meter, the method is as described in embodiment 2;

[0075] A system for judging the consistency of metering equipment based on graphic recognition, which includes: an image acquisition device and an image processor;

[0076] The image acquisition device is used to obtain the images of different parts of the three types of electricity mete...

Abstract

The invention discloses a method and a system for judging the consistency of a metering device based on pattern recognition. The method comprises: collecting images of different parts of an inspectedammeter by an industrial microscope; conveying the collected images to a determination system for image processing; acquiring and storing feature signals of binary images and the images of the different parts of the inspected ammeter into a database as standard feature signals of ammeters of the inspected batch; obtaining feature signals of images of different parts of a delivered ammeter or an onsite ammeter of the same batch as the inspected ammeter; and comparing the feature signals of the delivered ammeter or the onsite ammeter with the standard feature signals stored in the database to obtain the similarity, and determining the delivered ammeter or the onsite ammeter is an ammeter as same as the inspected ammeter according to the similarity. The method provided by the invention can automatically identify that whether the ammeter delivered by the ammeter supplier and the inspected ammeter are in the same batch and whether the onsite ammeter installed on the user site is artificially replaced, thereby reduce the manual workload, and improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a method and system for determining the consistency of measuring equipment based on graphic recognition. Background technique [0002] With the rapid development of smart grids and the wide application of big data analysis and processing of power consumption information collection, the methods of stealing electricity in power consumption information collection systems are becoming more and more intelligent and concealed. With the development of high-tech and network-based electricity theft, electricity theft that modifies and destroys the metering method occurs from time to time. Inconsistency, but at present, power companies often face the problem of difficulty in obtaining evidence when they discover the electricity theft, which is not conducive to the later processing of the electricity theft and the recovery of electricity bills. In the face of the current severe...
