Description

Technical Field

[0001] The invention relates to the field of remote meter reading, and in particular to an intelligent recognition system for a meter reading state with missing readings. Background Art

[0002] The residential centralized meter reading management system can realize the reading of electric meters, water meters, pure water meters and gas meters in the community network. It can automatically read, automatically bill, and query the status on the management computer of the community. It can record and print historical data, provide meter data interface, and perform manual modification, meter replacement and water, electricity and gas meter settlement under authorization. If the corresponding MODEM or router is added to the management center, external remote access can be realized. The remote meter reading system mainly completes three tasks: electricity metering or information collection, information remote transmission, and background software processing and analysis. The two parts of technology are mature, and the key to the meter reading system technology is to solve the problem of information remote transmission.

[0003] The readings obtained by remote meter reading should be evenly distributed on the surface. If the readings obtained by remote meter reading are unevenly distributed on the surface, there will inevitably be a loss of one or more readings. However, the spacing between the readings on the surface is a refined value, and the prior art lacks a targeted and refined reading missing analysis mechanism. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides an intelligent recognition system for the meter reading status with missing readings, which can identify the imaging areas corresponding to the readings in the filtering processing image based on the imaging features corresponding to the readings, obtain the central pixel points corresponding to the imaging areas, and obtain the horizontal coordinate values ​​corresponding to the central pixel points and the vertical coordinate values ​​corresponding to the central pixel points, and send a reading missing identification signal when the standard deviation of the horizontal coordinate values ​​and the mean of the standard deviation of the vertical coordinate values ​​are greater than or equal to the set standard deviation threshold, thereby realizing the intelligent recognition of the meter reading status with missing readings.

[0005] According to the present invention, there is provided an intelligent recognition system for a meter reading state with missing readings, the system comprising:

[0006] A front-end capturing mechanism is arranged at the front end of the remote meter reading device and is used to perform time-sharing shooting operations on the front-end environment of the remote meter reading device at uniform time intervals to obtain a captured image corresponding to a current timestamp;

[0007] A first enhancement mechanism, which is arranged inside the remote meter reading device and connected to the front-end capture mechanism, is used to perform image frequency domain enhancement processing on the captured image corresponding to the received current timestamp to obtain and output a corresponding frequency domain enhanced image;

[0008] A second enhancement mechanism, connected to the first enhancement mechanism, for performing a spatial domain differential sharpening process on the received frequency domain enhanced image to obtain and output a corresponding spatial domain sharpened image;

[0009] a third enhancement mechanism, connected to the second enhancement mechanism, for performing a smoothing linear filtering process and a salt-and-pepper noise elimination process on the received spatial domain sharpened image, so as to obtain and output a corresponding filtered processed image;

[0010] A reading detection mechanism, arranged inside the remote meter reading device and connected to the third enhancement mechanism, is used to identify the imaging areas corresponding to the readings in the received filtered processed image based on the imaging features corresponding to the readings, and obtain the central pixel points corresponding to the imaging areas;

[0011] A missing identification mechanism is connected to the reading detection mechanism, and is used to obtain the respective horizontal coordinate values ​​corresponding to the respective central pixel points and the respective vertical coordinate values ​​corresponding to the respective central pixel points, and to send a missing reading identification signal when the standard deviation of the respective horizontal coordinate values ​​and the mean of the standard deviation of the respective vertical coordinate values ​​are greater than or equal to a set standard deviation threshold;

[0012] Wherein, the missing identification mechanism is further used to send a reading missing unidentified signal when the mean of the standard deviation of the horizontal coordinate values ​​of the copies and the standard deviation of the vertical coordinate values ​​of the copies is less than the set standard deviation threshold;

[0013] Among them, identifying each imaging area corresponding to each reading in the received filtered processed image based on the imaging feature corresponding to the reading, and obtaining each central pixel point corresponding to each imaging area includes: the imaging feature corresponding to the reading is the color imaging feature of the dial reading of the meter reading object at the front end of the remote meter reading device.

[0014] It can be seen that the present invention has at least the following three important inventive concepts:

[0015] Firstly, the captured image of the front-end environment of the remote meter reading device is subjected to targeted enhancement processing in sequence, including image frequency domain enhancement processing, spatial domain differential sharpening processing, smooth linear filtering processing, and salt and pepper noise elimination processing, so as to obtain a filtered processed image with better image quality, providing more reliable basic data for the subsequent identification of the meter reading status;

[0016] Secondly: based on the imaging features corresponding to the readings, the respective imaging areas corresponding to the respective readings in the image are identified and filtered to obtain the respective central pixel points corresponding to the respective imaging areas, and the respective horizontal coordinate values ​​corresponding to the respective central pixel points are obtained, and the respective vertical coordinate values ​​corresponding to the respective central pixel points are obtained, and when the standard deviation of the respective horizontal coordinate values ​​and the mean of the standard deviation of the respective vertical coordinate values ​​are greater than or equal to the set standard deviation threshold, a missing reading identification signal is issued, thereby realizing the intelligent identification of the meter reading state of missing readings;

[0017] Again: when filtering and processing each imaging area corresponding to each reading in the image based on the imaging feature identification corresponding to the reading, the imaging feature corresponding to the reading is the color imaging feature of the dial reading of the meter reading object at the front end of the remote meter reading device, that is, the numerical distribution range of each color channel of the dial reading of the meter reading object at the front end of the remote meter reading device in the CMYK color space.
