[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0049] It should be understood that the various steps described in the method embodiments of the present disclosure may be executed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this regard.

[0050] As used herein, the term "comprising" and its variations are open-ended, that is, "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0051] In the related art, an intelligent electric meter is mainly a device for measuring and recording power consumption and uploading the recorded data to the power system, and the accuracy of its data directly affects the operation efficiency of the power system and user billing.

[0052] In order to ensure the accuracy of the data collected by the intelligent electric meter, in the related art, it is usually to check the intelligent electric meter manually by professional personnel to determine the operation status of the intelligent electric meter. However, the method of manual inspection cannot process a large number of intelligent electric meters in the same area, and there are problems of time-consuming and low efficiency.

[0053] Therefore, in order to reduce the labor cost of manual inspection and optimize the power management process, there is an urgent need for an intelligent electric meter data processing method that can be efficient and automated to automatically inspect the intelligent electric meter based on the data uploaded by the intelligent electric meter to ensure the efficient operation of the power system and the accuracy of user billing.

[0054] In order to solve the technical problems existing in the related art, an embodiment of the present invention provides a method for evaluating the state of a power metering device. Please refer to Figure 1 , Figure 1 is a schematic flowchart of a method for evaluating the state of a power metering device provided by an embodiment of the present invention. The method includes steps 101 to 104;

[0055] Step 101, obtain the first electric meter data uploaded by the first electric meter and the first electric meter image of the first electric meter uploaded by the user.

[0056] Among them, the first electric meter data includes at least one type of acquisition data collected by the first electric meter. The acquisition data can be the reportable data that the first electric meter can collect, such as power consumption data, environmental parameter data, voltage data, current data, identification data, etc. Specifically, these acquisition data can be collected by various sensors integrated in the first electric meter and sent to the first electric meter, such as voltage sensors, current sensors, temperature sensors, humidity sensors, etc., or can be the data collected by sensors independently arranged outside the first electric meter and sent to the first electric meter. The image of the first electric meter uploaded by the user can contain information such as the appearance of the electric meter, the status of the indicator lights, the position of the buttons, the internal structure, etc., which is convenient for characterizing the physical condition of the electric meter.

[0057] It should be noted that the acquisition data collected by the first electric meter data is not limited to the data collected by the first electric meter once, but can also be the data collected multiple times, such as multiple times within a preset time.

[0058] Step 102, determine the first status information of the first electric meter in the current state according to the first electric meter data, and determine the environmental status information of the environment where the first electric meter is currently located according to the first electric meter data.

[0059] In this embodiment, the first status information provided in this embodiment can characterize the operating performance of the first electric meter, such as whether the electric meter is working normally and whether the working state is stable. Among them, this embodiment can determine the operating performance of the first electric meter by analyzing the electric meter operation data of the first electric meter. Specifically, please refer to Figure 2 , Figure 2 which is a schematic flowchart of a process for determining the first status information provided by an embodiment of the present invention. As Figure 2 shown, it includes steps 201 to 203;

[0060] Step 201, according to the identification information in the first electric meter data and the electric meter operation data within a preset time period, determine the first operation data change curve of the electric meter operation data of the first electric meter in the current state, and the second operation data change curve of the electric meter operation data of the first electric meter in the initial state.

[0061] Among them, the electric meter operation data provided in this embodiment includes the voltage data and temperature data when the first electric meter is running. The temperature data is not the environmental temperature data, but the operating temperature of the processing chip when the first electric meter is running. The voltage data can be used to analyze whether there is an abnormal fluctuation in the first electric meter, and the temperature data can be used to analyze whether there is an overheating phenomenon in the first electric meter, so as to determine the current operating state of the first electric meter.

[0062] In this embodiment, it is possible to collect the operation data of the electricity meter within a preset time period, such as the voltage data and temperature data of the electricity meter within 72 hours. By creating a curve of the change in operation data from the voltage data and temperature data, it is possible to visually analyze the voltage stability and temperature change trend of the electricity meter during operation within 72 hours. By carefully analyzing these curves of the change in operation data, it is possible to effectively identify potential operation problems of the electricity meter. For example, abnormal voltage fluctuations may indicate instability in the power supply, while abnormal temperature increases may mean that there is an overloading or insufficient heat dissipation in the internal components of the electricity meter. Ultimately, this information will assist in maintenance work and facilitate timely measures to ensure the long-term stability and safety of the operation of the electricity meter.

[0063] By continuously tracking the performance of the electricity meter and combining it with a pre-trained electricity meter performance prediction model, it is possible to more accurately predict the possible failures that may occur, thereby taking preventive measures to reduce downtime and maintenance costs. At the same time, such analysis can also provide a basis for the replacement of aging electricity meters to ensure that the electricity meter is always in the best working condition. Specifically, both the failures and aging of the electricity meter can be determined by analyzing the fluctuation amplitude of the curve of the change in operation data. The specific value of the fluctuation amplitude can be determined according to the model of the electricity meter and will not be specifically limited here. In this way, by regularly evaluating this data, it is possible to timely adjust the maintenance plan and even perform preventive intervention before problems occur.

[0064] In order to analyze whether the voltage stability and temperature change trend of the first electricity meter are normal trends, this embodiment can set a series of threshold parameters. If the curve of the change in operation data falls within the normal threshold range, it is considered that the electricity meter is operating normally; if there is a deviation, for example, the voltage fluctuation exceeds the set normal fluctuation threshold or the temperature exceeds the normal temperature threshold, the system will issue a warning signal. In this way, real-time monitoring and early warning of the operation status of the electricity meter can be achieved to ensure the stable operation of the electricity meter and the reliability of the power supply system.

[0065] Similarly, in order to better determine whether the curve of the change in the first operation data of the first electricity meter is a normal trend, this embodiment can also synchronously determine the operation data of the first electricity meter in its initial state, that is, in the normal state (in a scenario without any other interfering factors), so as to facilitate comparative analysis. Through such a comparison, it is possible to more accurately determine the performance of the first electricity meter under specific operating conditions and thus identify problems that only appear under specific circumstances.

[0066] Step 202: Compare and process the curve of the change in the first operation data and the curve of the change in the second operation data to obtain the information on the difference in the operation data of the first electricity meter relative to the initial state.

[0067] To further enhance the monitoring ability of the electricity meter, in this embodiment, the real-time operation data of the electricity meter can be first compared and analyzed with the operation data of the electricity meter in the normal state to evaluate the operation trend of the current electricity meter relative to the electricity meter in the normal state. Then, a comprehensive evaluation is carried out by combining subsequent multi-dimensional evaluation data, namely the second state information and the environmental state information, so as to effectively improve the accuracy of the electricity meter state evaluation.

[0068] Specifically, the electricity meter operation data difference information can be the fluctuation amplitude between the first operation data change curve and the second operation data change curve.

[0069] Step 203, use the electricity meter operation data difference information as the first state information of the first electricity meter in the current state.

[0070] After obtaining the electricity meter operation data difference information, the electricity meter operation data difference information can be used as the first state information of the first electricity meter in the current state, so as to facilitate subsequent combination with evaluation data of other dimensions and comprehensive evaluation.

[0071] In this embodiment, the environmental state information provided in this embodiment can characterize the external conditions under which the first electricity meter operates, including but not limited to ambient temperature, humidity, electromagnetic interference, etc. Combining these information can provide a more comprehensive understanding of the working environment of the electricity meter and provide more detailed data support for preventive maintenance and troubleshooting. Among them, this embodiment can determine the potential impact on the operation status of the first electricity meter by analyzing the environmental parameter data of the environment where the first electricity meter is located. Specifically, please refer to Figure 3 , Figure 3 is a schematic flowchart of a process for determining the environmental state information provided by an embodiment of the present invention. As Figure 3 shown, it includes steps 301 to step 303;

[0072] Step 301, according to the identification information in the first electricity meter data and the environmental parameter data within a preset time period, determine the first environmental change curve of the environment where the first electricity meter is located, and the second environmental change curve of the first electricity meter in the standard environment in the initial state.

[0073] In this embodiment, the environmental parameter data within a preset time period can be collected, for example, the environmental parameter data within 72 hours. By making the environmental parameter data within 72 hours into an operation data change curve, the environmental change trend of the electricity meter within 72 hours can be visually analyzed to determine the impact of the environmental change where the first electricity meter is located on the operation of the electricity meter.

[0074] Meanwhile, in order to evaluate the specific impact of environmental changes on the condition of the first electricity meter, this embodiment also needs to determine the second environmental change curve of the first electricity meter in the initial state in a standard environment (an environment that has no impact on the normal operation of the electricity meter). By comparing these two environmental change curves, the potential impact of environmental factors on the operating state of the electricity meter can be evaluated, expanding the electricity meter monitoring from simple performance detection to environmental adaptability assessment, and ensuring the stability and reliability of the electricity meter under various environmental conditions.

[0075] In addition, this embodiment can also be trained based on a large amount of historical data and examples to establish a complex association model between the electricity meter state and environmental factors. Then, combined with the real-time monitored environmental parameter data, it can timely detect and solve the electricity meter abnormal problems caused by environmental changes, thereby improving the overall operating efficiency and accuracy of the electricity meter. In this way, misreading and failures caused by environmental factors can be greatly reduced, and the operation and maintenance management level of the power system can be improved.

[0076] Step 302: Compare and process the first environmental change curve and the second environmental change curve to obtain the environmental difference information of the current environment of the first electricity meter relative to the standard environment in the initial state.

[0077] Specifically, the environmental difference information can be the fluctuation amplitude between the first environmental change curve and the second environmental change curve. The magnitude of the fluctuation amplitude can reflect the specific impact degree of environmental changes on the operating condition of the electricity meter. By analyzing these fluctuation characteristics in detail, the key environmental factors causing the performance fluctuation of the electricity meter can be identified, and corresponding adjustment or optimization measures can be formulated.

[0078] Step 303: Use the environmental difference information as the environmental state information of the first electricity meter in the current environment.

[0079] After obtaining the environmental difference information, this environmental difference information can be used as the environmental state information of the first electricity meter in the current environment, so as to facilitate subsequent combination with evaluation data in other dimensions for comprehensive evaluation and improve the evaluation accuracy of the electricity meter state.

[0080] Step 103: Determine the current second state information of the first electricity meter according to the first electricity meter data and the first electricity meter image.

[0081] In this embodiment, since the first electricity meter data provided in this embodiment may include identification information, the electricity meter model of the first electricity meter can be determined according to the first electricity meter data, and thus the image information of the corresponding electricity meter in the database can be found based on the electricity meter model. Combining the image information, the appearance condition of the electricity meter can be visually analyzed to determine whether there are problems such as wear, stains, or damage. In addition, the accuracy of the electricity meter reading can also be detected through image recognition technology to ensure that the collected data is true and reliable. Through the double verification of the electricity meter data and the image information, a more comprehensive and accurate basis is provided for the status evaluation of the electricity meter.

[0082] Specifically, please refer to Figure 4 , Figure 4 which is a schematic flowchart of a process for determining the second status information provided by an embodiment of the present invention. As Figure 4 shown, it includes steps 401 to 403;

[0083] Step 401, determine the second electricity meter image of the first electricity meter in the initial state according to the identification information in the first electricity meter data.

[0084] In this embodiment, this embodiment can pre - construct a database for storing the image information of different electricity meter models in the initial state, so as to intuitively identify any changes in the appearance of the electricity meter, such as color fading, physical damage, or structural deformation, by comparing the currently obtained electricity meter image with the electricity meter image in the initial state, further ensuring the accuracy of the electricity meter status evaluation.

[0085] Step 402, perform a comparison process on the target areas in the first electricity meter image and the second electricity meter image to obtain the appearance difference information of the target area in the first electricity meter image relative to the initial state.

[0086] In this embodiment, the target areas provided in this embodiment can be key parts such as the electricity meter dial, electricity meter pointer, and electricity meter dial display screen that can evaluate the appearance change of the electricity meter. Optionally, the step of performing a comparison process on the target areas in the first electricity meter image and the second electricity meter image to obtain the appearance difference information of the target area in the first electricity meter image relative to the initial state provided in this embodiment can specifically be: perform an identification process on the first electricity meter image to obtain the first feature information of the target area in the first electricity meter image; perform a comparison process on the second feature information of the target area in the second electricity meter image and the first feature information to obtain the appearance difference information of the target area in the first electricity meter image relative to the initial state.

[0087] Among them, the feature information includes the glass transmittance of the electricity meter dial, the deflection angle of the electricity meter pointer, and the display defect area of the display screen of the electricity meter dial.

[0088] In addition, to avoid the situation where the display screen of the electricity meter dial is normal but the internal structure, such as the chip, is abnormal, the target area provided in this embodiment may further include the internal chip assembly of the electricity meter. In this way, high-precision image recognition and analysis technologies can be used to carefully inspect the solder joints on the surface of the internal chip assembly of the electricity meter, the integrity of the circuit board, and whether there are short circuits or burnout phenomena.

[0089] Similarly, in order to determine whether there are differences between the first electricity meter image and the electricity meter image of the electricity meter in the initial state, that is, the normal state, this embodiment needs to establish a standard image database to store the detailed image information of the inside and outside of the electricity meter of different electricity meter models in the normal state. In this way, any minor changes, such as the solder joint offset on the chip assembly or the minor crack on the circuit board, can be detected and recorded by comparing with the standard images in this database. In this way, even internal abnormalities that are difficult to visually observe can be accurately detected, thereby improving the early detection rate and repair efficiency of electricity meter failures.

[0090] Step 403, use the appearance difference information as the second state information of the first electricity meter at present.

[0091] After obtaining the appearance difference information, the appearance difference information can be used as the second state information of the first electricity meter at present, so as to facilitate combination with the first state information and the environmental state information determined in the above embodiments to more comprehensively evaluate the current electricity meter state of the electricity meter.

[0092] As an optional embodiment, to ensure the accuracy and comparison efficiency of the comparison process between the first electricity meter image and the second electricity meter image, this embodiment may further perform the following steps before step 402: perform image quality evaluation processing on the first electricity meter image to obtain an evaluation result; when the evaluation result indicates that the first electricity meter image meets the target conditions, return the evaluation result and the corresponding shooting suggestions to the user, and the target conditions include that the image blur exceeds the target threshold and the target area is blocked.

[0093] By performing image quality evaluation processing on the image uploaded by the user, and when the image quality evaluation result does not meet the target conditions, prompting the user to re-acquire the image, and after the user completes re-shooting, performing image quality evaluation again until the requirements are met. In this way, the accuracy of the comparison process is ensured, and reliable second state information of the first electricity meter is generated, providing a solid data basis for the final electricity meter state evaluation.

[0094] Step 104: Based on the first status information, the second status information, and the environmental status information, evaluate the current meter status of the first electric meter to obtain the evaluation result of the current meter status of the first electric meter.

[0095] In this embodiment, an evaluation strategy library can be preset in advance to store various preset evaluation rules and meter status determination logics. Based on these rules, the first status information, the second status information, and the environmental status information can be comprehensively considered to perform multi-dimensional analysis and evaluation on the electric meter. Specifically, in this embodiment, the association patterns and weights among the first status information, the second status information, and the environmental status information can be determined from a large amount of historical data (including the first status information, the second status information, the environmental status information, and the meter status evaluation results of the electric meter) in advance, and then an evaluation model can be constructed. In the evaluation processing stage, the difference score is calculated by matching the evaluation rules in the evaluation strategy library, and the meter status is accurately judged according to the preset evaluation threshold range, such as judging whether there are faults or equipment aging problems with the electric meter. Finally, these evaluation results are provided to maintenance personnel and management personnel to take corresponding maintenance measures or preventive strategies in a timely manner to ensure the stable operation of the electric meter.

[0096] Specifically, the step of evaluating the current meter status of the first electric meter based on the first status information, the second status information, and the environmental status information to obtain the evaluation result of the current meter status of the first electric meter provided in this embodiment can specifically be: According to the identification information in the first electric meter data, obtain the set of weight coefficients corresponding to the first electric meter from the preset evaluation strategy library. The set of weight coefficients includes the first weight coefficient corresponding to the difference information of the electric meter operation data, the second weight coefficient corresponding to the appearance difference information, and the third weight coefficient corresponding to the environmental difference information. The sum of the first weight coefficient, the second weight coefficient, and the third weight coefficient is 1; Based on the difference information of the electric meter operation data and the first weight coefficient, the appearance difference information and the second weight coefficient, and the environmental difference information and the third weight coefficient, calculate the difference score of the first electric meter relative to the initial state; Compare the difference score with the preset evaluation threshold range to obtain the evaluation result of the current meter status of the first electric meter. The evaluation threshold range includes a first range, a second range, and a third range. The second range is greater than the first range, and the third range is greater than the second range. The meter status evaluation result includes the normal meter status result corresponding to the first range, the meter status aging result corresponding to the second range, and the abnormal meter status result corresponding to the third range.

[0097] Optionally, after determining that the evaluation result of the electricity meter status is an abnormal result of the electricity meter status, this embodiment can analyze the specific differences between the first status information, the second status information, and the environmental status information and the initial status respectively to identify the specific reasons for the abnormality. For example, if the specific difference between the environmental status information and the initial status is too large, it can indicate that the environment around the first electricity meter is abnormal, such as the temperature and humidity exceeding the normal operating range. At this time, these differences can be recorded, and possible fault modes or potential risks can be mined through data analysis, so as to provide precise problem location and handling suggestions for maintenance personnel, thereby ensuring the stability and safety of the entire power system. Another example is that if the specific difference between the first status information and the initial status is too large, it can indicate that there may be a short circuit or other faults in the internal operating circuit of the electricity meter, and further inspection and repair are required.

[0098] Meanwhile, this embodiment can also adjust the evaluation weights corresponding to the first status information, the second status information, and the environmental status information in the evaluation strategy library based on the first status information, the second status information, and the environmental status information. Specifically, when the difference values represented by the first status information, the second status information, and the environmental status information reach the difference values corresponding to equipment abnormality or equipment aging, the weights of the relevant evaluation rules in the evaluation strategy library can be increased, so as to optimize the accuracy of the evaluation model. For example, if the environmental status information shows long-term exposure to harsh weather conditions, the proportion of the environmental status information in the evaluation process can be increased, so as to more accurately reflect the actual operating conditions and potential risks of the electricity meter. This dynamic adjustment mechanism ensures that the evaluation strategy library can always adapt to different usage scenarios and improves the effectiveness and practicality of the electricity meter status evaluation.

[0099] In addition, this embodiment can also include a feedback mechanism that allows maintenance personnel to mark the evaluation results according to actual maintenance experience, and then continuously optimize the evaluation rules in the evaluation strategy library. Through this cyclic improvement process, the accuracy and reliability of the electricity meter status evaluation are continuously improved.

[0100] In this way, by deeply integrating and analyzing the image data of the electricity meter with the electricity meter operation data and the environmental parameter data, the health status of the electricity meter can be evaluated more comprehensively. In this way, the operation and maintenance team can quickly locate problems and take corresponding measures to ensure that the electricity meter can accurately record power consumption, thereby providing more reliable data support for users and power companies.

[0101] As an alternative embodiment, in order to evaluate the current meter status of the first meter and obtain the evaluation result of the current meter status of the first meter, before the step of evaluating the current meter status of the first meter according to the first status information, the second status information, and the environmental status information to obtain the evaluation result of the current meter status of the first meter, this embodiment may further include: obtaining a training data set of second meters with multiple different identification information, where the training data set includes the to-be-trained parameter information corresponding to each second meter and the meter status evaluation result, and the to-be-trained parameter information includes the first status information, the second status information, and the environmental status information corresponding to the second meter; using the training data set to train the to-be-trained meter status evaluation model until convergence to obtain the meter status evaluation model.

[0102] After obtaining the meter status evaluation model, the step of evaluating the current meter status of the first meter according to the first status information, the second status information, and the environmental status information to obtain the evaluation result of the current meter status of the first meter provided in this embodiment may specifically be: inputting the first status information, the second status information, and the environmental status information into the meter status evaluation model to evaluate the current representative status of the first meter to obtain the current status evaluation result of the first meter, where the status evaluation result includes three statuses: normal, warning, and failure.

[0103] In this way, using the meter status evaluation method with multi-dimensional data fusion and intelligent learning mechanism provided in the embodiments of the present invention will help build a more intelligent and accurate power monitoring system, laying a solid foundation for ensuring the stability and reliability of power supply.

[0104] In summary, the embodiments of the present invention provide a method for evaluating the status of a power metering device. The method includes obtaining the first meter data uploaded by the first meter and the first meter image of the first meter uploaded by the user, determining the first status information of the first meter in the current state according to the first meter data, and determining the environmental status information of the environment where the first meter is currently located according to the first meter data, determining the current second status information of the first meter according to the first meter data and the first meter image, and evaluating the current meter status of the first meter according to the first status information, the second status information, and the environmental status information to obtain the evaluation result of the current meter status of the first meter.
