[0038] By adopting the above technical solution, the image features obtained by feature extraction of image information are calculated with the preset image features to obtain a similarity value. When the similarity value is greater than the preset similarity threshold, it is determined that the image information corresponding to the image features is an instrument damaged image.

[0068] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0069] In the related art, the calibration of instruments is generally carried out using a calibration station, which records data pulses to make error judgments on the instruments, and sends the judgment results to the display platform after obtaining the judgment results. The staff modifies the instrument coefficient according to the judgment results displayed on the display platform. However, when there are many instruments to be calibrated, the staff cannot modify the instrument coefficient of the instrument according to the judgment results of the calibration station in real time, and the work efficiency is low.

According to the acquired initial data information and the first data information and the preset time, the flow rate is calculated to obtain the actual flow rate data, and the actual flow rate data is judged with the preset flow rate data. When the actual flow rate data is different from the preset flow rate data, the flow rate difference obtained by the difference calculation between the actual flow rate data and the preset flow rate data is used to correct the instrument. By judging the relationship between the actual flow rate data and the preset flow rate data, when the actual flow rate data is different from the preset flow rate data, the flow rate difference obtained by the difference calculation between the actual flow rate data and the preset flow rate data is used to correct the instrument, thereby improving the working efficiency of the instrument calibration.

[0072] Combination Figure 1 , Figure 1 The following is a flow chart of an instrument calibration method provided in an embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102, step S103, step S104, step S105 and step S106, wherein:

[0073] Step S101, obtaining initial data information of the instrument.

[0074] Among them, the initial data information of the meter is the current cumulative flow size of the meter. After receiving the meter calibration instruction, the electronic device obtains the initial data information of the meter. The meter calibration instruction can be triggered by the user clicking the meter calibration start button or by voice triggering. The embodiment of the present application is not limited to this.

[0075] Step S102, obtaining first data information of the meter, where the first data information is data information of the meter after a preset time has passed.

[0076] Among them, after a preset time has passed, first data information of the meter is obtained, and the first data information is the accumulated flow size of the meter after the preset time has passed.

[0077] Step S103, performing flow calculation according to the initial data information, the first data information and the preset time to obtain actual flow data.

[0078] After obtaining the initial data information and the first data information of the meter, the actual flow data of the meter is calculated to calculate the accumulated flow recorded by the meter. The actual flow data is the flow data obtained by the meter after calculation.

[0079] Step S104, determining whether the actual flow data is the same as the preset flow data.

[0080] Among them, the electronic device pre-stores preset flow data, which is the flow size after a preset time. The accuracy of the meter can be determined by judging whether the actual flow data is the same as the preset flow data.

[0081] Step S105: If they are not the same, a difference calculation is performed based on the actual flow data and the preset flow data to obtain a flow difference.

[0082] When it is determined that the actual flow data is different from the preset flow, the difference between the actual flow data and the preset flow data is calculated to obtain the flow difference between the actual flow data and the preset flow data, wherein the flow difference can be used to correct the instrument accuracy.

[0083] Step S106, correcting the meter according to the flow difference.

[0084] Among them, after determining the flow difference, the accuracy of the instrument can be corrected according to the flow difference. The embodiment of the present application does not limit the method of correcting the accuracy of the instrument, and the user can customize the settings according to needs.

[0085] In an embodiment of the present application, flow calculation is performed based on the acquired initial data information, the first data information and the preset time to obtain actual flow data, and the actual flow data is judged against the preset flow data. When the actual flow data is different from the preset flow data, the meter is corrected based on the flow difference value obtained by performing a difference calculation between the actual flow data and the preset flow data. By judging the relationship between the actual flow data and the preset flow data, when the actual flow data is different from the preset flow data, the meter is corrected based on the flow difference value obtained by performing a difference calculation between the actual flow data and the preset flow data, thereby improving the work efficiency of the instrument calibration.

[0086] A possible implementation of the embodiment of the present application is to calculate the difference between the actual flow data and the preset flow data to obtain the flow difference, which includes:

[0087] Obtain unit information of actual flow data and unit information of preset flow data;

[0088] Convert the unit information of the actual flow data according to the unit information of the preset flow information to obtain the converted flow data;

[0089] The flow difference is calculated based on the preset flow data and the converted flow data to obtain the flow difference.

[0090] Flow rate refers to the amount of fluid flowing through the effective cross-section of a closed pipe or open channel per unit time. The unit is generally cubic meters per second. However, on the instrument, the flow rate is generally expressed by the rotation speed. Therefore, when performing difference calculation based on the actual flow data and the preset flow data, it is necessary to convert the unit of the actual flow data. The unit information of the actual flow data is converted according to the unit information of the preset flow data to obtain the converted flow data. The unit information of the converted flow data is the same as the unit information of the preset flow data. The difference calculation is performed based on the converted flow data and the preset flow data to obtain the flow difference.

[0091] In an embodiment of the present application, the unit of actual flow data is converted according to the unit information of preset flow data to obtain the converted flow data, and the difference between the converted flow data and the preset flow data is calculated to obtain the flow difference. By converting the unit of actual flow data according to the unit information of preset flow data, the accuracy of flow difference calculation is improved.

[0092] A possible implementation of the embodiment of the present application, correcting the instrument according to the flow difference includes:

[0093] Calculate the coefficient according to the preset flow data, the initial data information and the first data information to obtain the instrument coefficient;

[0094] Correct the instrument according to the instrument factor.

[0095] In order to obtain the final metering indication of the measuring instrument, a coefficient must be multiplied to the directly displayed indication, and this coefficient is the instrument coefficient. The electronic device pre-stores preset flow data. After determining that the actual flow data is different from the preset flow data, the actual flow data is calculated based on the initial data information and the first data information, and the instrument coefficient is calculated based on the actual flow data and the preset flow data. The instrument is corrected according to the instrument coefficient.

[0096] In the embodiment of the present application, coefficient calculation is performed based on preset flow data, initial data information and first data information to obtain instrument coefficient, and the instrument is corrected based on the instrument coefficient, thereby improving the accuracy of instrument correction.

[0097] A possible implementation of the embodiment of the present application, after correcting the instrument according to the instrument coefficient, further includes:

[0098] Get the instrument number information;

[0099] Determine whether there is an instrument with the same serial number information among all instruments;

[0100] If it exists, the instrument with the same number information will be corrected according to the instrument coefficient.

[0101] Among them, the numbering information is the corresponding assembly line information when the instrument is produced, that is, the same batch of instruments produced by the same assembly line have the same numbering information. Therefore, after determining the instrument coefficient, correcting the instrument coefficient of the same batch of instruments according to the obtained numbering information can improve the efficiency of instrument correction.

[0102] In the embodiment of the present application, it is determined whether there is an instrument with the same number information among all the instruments. If so, all the instruments with the same number information are corrected according to the instrument coefficient, thereby improving the work efficiency of instrument coefficient correction.

[0103] A possible implementation of the embodiment of the present application, after correcting the meter according to the flow difference, further includes:

[0104] Get the image information of the instrument;

[0105] Determine whether the instrument is damaged based on the image information;

[0106] If it is damaged, an alarm message is generated based on the image information and an alarm is sounded.

[0107] When calibrating the instrument, a camera device can be placed in front of the instrument panel, and the camera device can capture the image information of the instrument. After obtaining the instrument image information, it is determined whether the instrument is damaged based on the instrument image information. The embodiment of the present application does not limit the method for determining whether the instrument is damaged. The judgment can be made using a trained neural network model, or by using computer vision technology to judge the image information.

[0108] When it is determined that the instrument is damaged, an alarm message is generated and an alarm is sounded based on the image information and the preset alarm template. The embodiment of the present application does not limit the preset alarm template, which can be "The current instrument is damaged, please deal with it in time!!!" Of course, it can also be other templates, which are not limited by the embodiment of the present application.

[0109] In the embodiment of the present application, it is determined whether the instrument is damaged based on the acquired image information. If damaged, alarm information is generated and an alarm is sounded based on the image information, thereby improving the practicality of instrument image detection.

[0110] A possible implementation of the embodiment of the present application, judging whether the instrument is damaged according to the image information, includes:

[0111] Extract features from image information to obtain image features;

[0112] Calculate similarity between the image features and the preset image features to obtain a similarity value;

[0113] If the similarity value is greater than a preset similarity threshold, it is determined that the instrument corresponding to the image information is damaged.

[0114] Preset image features are pre-stored in the electronic device. After the image information is feature extracted to obtain the image features, the image features are similarly calculated with the preset image features to obtain a similarity value. The embodiment of the present application does not limit the similarity calculation method, which can be any one of the cosine similarity algorithm, hash algorithm, histogram, and SSIM (Structural Similarity, structural similarity measurement).

[0115] If the similarity value is greater than the preset similarity threshold, the image information corresponding to the image feature is determined to be an image of a damaged instrument. If the similarity value is not greater than the preset similarity threshold, the image information corresponding to the image feature is determined not to be an image of a damaged instrument. The embodiment of the present application does not limit the preset similarity threshold, and the user can set it according to experience.

[0116] In an embodiment of the present application, a similarity is calculated between image features obtained by extracting features from image information and preset image features to obtain a similarity value. When the similarity value is greater than a preset similarity threshold, it is determined that the image information corresponding to the image features is an image of a damaged instrument. By calculating the similarity between the image features and the preset image features, the accuracy of instrument image detection is improved.

[0117] A possible implementation of the embodiment of the present application, after correcting the instrument according to the instrument coefficient, further includes:

[0118] Get multiple meter factors;

[0119] Predict the initial instrument coefficient according to multiple instrument coefficients to obtain a prediction result;

[0120] Set the initial instrument factor for the instrument based on the prediction results.

[0121] Among them, in the embodiment of the present application, the method for predicting the initial instrument coefficient based on multiple instrument coefficients is not limited. It can be to calculate the average of the instrument coefficients based on multiple instrument coefficients, wherein the average of the instrument coefficients is the prediction result; or it can be to generate an instrument coefficient bar chart based on multiple instrument coefficients, and use a big data analysis method to predict the initial instrument coefficient to obtain a prediction result.

[0122] In an embodiment of the present application, the initial instrument coefficient is predicted based on multiple acquired instrument coefficients to obtain a prediction result, and the initial instrument coefficient of the instrument is set based on the prediction result, thereby reducing the error category of the initial instrument coefficient and improving the work efficiency of instrument calibration.
