Detailed Implementation
[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0042] In this application, a module refers to a functional module or a logical module.

The character " / " generally indicates that the preceding and following related objects have an "OR" relationship.
[0043] First, the terms used in the embodiments of this application will be explained.
[0044] CSV: Short for Comma-Separated Values, it is a commonly used text file format for storing tabular data, such as spreadsheets or databases. A CSV file consists of one or more lines of text, each line containing one or more fields separated by commas. These fields typically represent columns in a table, and each line of text represents a row in the table.
[0045] bin: an abbreviation for binary, a file format, indicating a file with the ".bin" extension.
[0046] An electronic flow meter is a commonly used type of flow meter, consisting of a base meter and a controller. The base meter collects flow data from the site, while the controller parses and processes the data collected by the base meter. During the product development of an electronic flow meter, testing is necessary to ensure the accuracy of the controller algorithm.
[0047] In existing technologies, testing of electronic flow meters needs to be conducted in real-world scenarios, taking into account issues such as equipment aging and regular maintenance, resulting in high testing costs.
[0048] To address the aforementioned technical issues, the instrument testing method provided in this application can generate a simulated flow field data file by collecting flow field data from a single test site. The simulated flow field data file can then be used to simulate testing of the instrument, eliminating the need for subsequent maintenance work at the test site and effectively reducing testing costs.
[0049] The technical solutions of this application are illustrated below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0050] Figure 1 This is a schematic flowchart illustrating a meter testing method according to an embodiment of this application. The subject executing this method can be a meter testing device. Figure 1 As shown, the method may include:
[0051] S101, Obtain the flow field data measured by the instruments at the test site to obtain a flow field data file, wherein the flow field data file includes flow field data in string format.
[0052] The flow field data includes flow rate data at different time points. In practical applications, flow field data files can be acquired in two ways. Figure 2 This is a schematic diagram illustrating a process for acquiring flow field data files, provided as an embodiment of this application. Figure 2 As shown, in one possible implementation, the flow field data includes flow rate data at different time points. The flow field data is obtained by acquiring flow field data measured by instruments at the test site, resulting in a flow field data file, including:
[0053] Connect the flow field data capture tool to the meters at the test site, periodically capture the flow data of the meters at the test site, and save it in the process data file in the storage medium;
[0054] Read the flow field data file from the storage medium.
[0055] In practical implementation, the flow field data acquisition fixture can be connected to a computer. The fixture periodically (e.g., every 2 seconds) reads the flow data from the meters at the test site and saves it to a storage medium. After the meters at the test site complete data acquisition, the complete flow field data file can be read from the storage medium.
[0056] For example, the instruments at the test site can be connected to the gripping fixture via infrared or serial port.
[0057] like Figure 2 As shown, in one possible implementation, flow field data measured by instruments at the test site is obtained to generate a flow field data file, including:
[0058] Connect the meters at the test site to the computer, and use a flow data acquisition tool to periodically read the flow data from the meters at the test site and save it in a flow field data file.
[0059] In practice, the meters at the test site can be connected to a computer. A flow data acquisition tool on the computer can periodically (e.g., every 2 seconds) read the flow data from the meters at the test site and save it to a flow field data file. Once the meters at the test site have completed data acquisition, a complete flow field data file can be obtained.
[0060] For example, the instruments at the test site can be connected to the computer via a data cable interface, or the instruments at the test site can be connected to the computer via infrared or serial port.
[0061] For example, flow data may include flow rate, flight time, temperature, and gain.
[0062] The flow field data can include multiple flow data at different time points. Each flow data can include: flow velocity, uplink flight time, downlink flight time, temperature, uplink gain, and downlink gain.
[0063] S102, import the flow field data file into the flow field simulation tool, and use the flow field simulation tool to convert the flow field data file into a simulated flow field data file. The simulated flow field data file includes flow field data in text format.
[0064] In practice, the flow field data in the flow field data file is in string format, such as hexadecimal strings. The flow field data file is imported into the flow field simulation tool, which, based on the data structure specification file of the field instruments, determines the header and tail intervals of each string of flow field data, as well as the length and unit of each data item within that string, thus converting the string-format flow field data into text-format flow field data. For example, suppose a string of flow field data in the flow field data file is [02 0000 00 68AB 39 58 68AB 39 58 00 00 1E 1E 00 03 01]. According to the data structure description file of the field instrument, the flow field simulation tool determines that the string of flow field data includes the data header 02, velocity 0000 00, uplink flight time 68AB 39 58, downlink flight time 68AB 39 58, temperature 00 00, uplink gain 1E, downlink gain 1E, and data tail 00 03 01. It also determines that the units of velocity, uplink flight time, downlink flight time, and temperature are all 1 / 10000, thus converting it into text form flow field data as [0.0000,175605.1800,175605.1800,0.0000,30,30].
[0065] For example, the flow field data file can be a txt file, and the simulated flow field data file can be a CSV file or a bin file.
[0066] S103, and, acquire the target data format of the instrument under test, convert the text-based flow field data into the target data format flow field data, and import the target data format flow field data into the controller of the instrument under test, thereby testing the instrument under test.
[0067] In practice, the flow field simulation tool can determine the target data format that the instrument under test can recognize based on the data structure specification file of the instrument under test, convert the text-based flow field data in the simulated flow field data file into flow field data in the target data format, and send it to the controller of the instrument under test, thereby testing the instrument under test.
[0068] In this embodiment, the flow field data in string format measured by the instrument at the test site is acquired. The flow field simulation tool converts this string data into text format and saves it as a simulated flow field data file. When testing the instrument under test, the text format flow field data is converted into the target data format and imported into the controller of the instrument under test. This allows for the simulation of the test site with only one set of flow field data collected, eliminating the need for subsequent maintenance and effectively reducing testing costs. Furthermore, testing the instrument under test only requires importing the flow field data, minimizing site requirements and supporting concurrent testing by multiple users, making testing more convenient and efficient. The flow field data from each test in the same scenario is consistent, effectively improving testing accuracy.
[0069] Figure 3 This is a schematic diagram illustrating a flow field data storage process provided in an embodiment of this application. Figure 3 As shown, in one possible implementation, the method further includes:
[0070] Save the simulated flow field data file to the simulated flow database;
[0071] Obtain the target data format of the instrument under test, and convert the text-based flow field data into the target data format, including:
[0072] Obtain the target simulated flow field data file corresponding to the instrument under test from the simulated flow database, and convert the text-based flow field data in the target simulated flow field data file into the target data format according to the target data format of the instrument under test.
[0073] In practical implementation, after generating the simulated flow field data file, it can be saved to the simulated flow database. The simulated flow database can uniformly manage simulated flow field data files from multiple test sites. When testing the instrument under test, the target flow field for this test can be determined first, the target simulated flow field data file corresponding to the instrument under test can be obtained from the simulated flow database, and the instrument under test can be tested using the target simulated flow field data file.
[0074] In one possible implementation, the method also includes:
[0075] Obtain the cumulative flow of the meter under test during the test period, and obtain the test results of the meter under test based on the cumulative flow.
[0076] Figure 4 This is a schematic diagram illustrating the process of sending flow data using the flow field simulation tool provided in this application embodiment. Figure 4As shown, when testing the instrument under test, the flow field simulation tool reads the simulated flow field data file corresponding to the target simulated flow field from the simulated flow database. The simulated flow field data file includes multiple simulated flow data entries, allowing the tool to generate a simulated flow data list. The tool then obtains the target data format of the instrument under test, reads each simulated flow data entry from the simulated flow data list, and converts each entry into the target data format, thus transforming the simulated flow data into data recognizable by the instrument under test. Finally, the tool sequentially sends the target data format simulated flow data to the controller of the instrument under test via a serial port or other communication method.
[0077] Figure 5 This is a schematic diagram illustrating the process of parsing flow data from the meter under test, as provided in an embodiment of this application. Figure 5 As shown, in the specific implementation, after the controller of the device under test receives multiple simulated flow data in target data format sent by the flow field simulation tool, it first verifies the validity of the data. If the data is valid, it parses each simulated flow data in target data format to obtain the flow velocity, uplink / downlink flight time, uplink / downlink gain, and temperature corresponding to each simulated flow data. Based on each simulated flow data, filtering is performed to remove abnormal data, and flow velocity processing, flow accumulation calculation, and flow anomaly detection are also performed to finally obtain the cumulative flow over the test period.
[0078] The computer can obtain the cumulative flow rate measured by the meter under test within the test period, determine whether the cumulative flow rate is accurate, and thus obtain the test result of the meter under test.
[0079] In one possible implementation, the flow field data file is converted into a simulated flow field data file using a flow field simulation tool, including:
[0080] The flow field data in string format is converted into flow field data in text format using a flow field simulation tool, and then the text flow field data is encrypted to obtain a simulated flow field data file.
[0081] In practice, when writing flow field data in text form to a simulated flow field data file, encryption can be performed to effectively improve data security.
[0082] This application also provides a meter testing device. Figure 6 This is a schematic diagram of the structure of the instrument testing device provided in an embodiment of this application. Figure 6 As shown, the instrument testing device 600 may include:
