DETAILED DESCRIPTION

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figures 1-8 As shown in the figure, a three-phase electric energy meter automatic meter inspection system is provided. The core of the system is to achieve efficient inspection through multi-threaded parallel processing and automated process control. The system includes: The meter inspection module consists of four submodules: basic error, daily timekeeping, communication verification, and current testing. The first three utilize multi-threaded parallel execution. The basic error module loops through the parameter array to initiate verification, configure test point parameters, and read data. The daily timekeeping module loops through the test three times and calculates the average. The communication verification module performs communication tests on a project-by-project basis and evaluates the data. The current test module controls console operation and reads current data.

[0018] Data processing and storage module: performs calculations and judgments on the collected data, such as error average calculation, daily timing error judgment, etc., and saves the results to the production data and EIP data storage table.

[0019] System management and query module: Set communication parameters, platform parameters and operator permissions, and support querying and exporting data according to multiple conditions.

[0020] Log recording module: records operation logs and communication logs, and saves them to TXT files named with time and module.

[0021] The meter inspection module is divided into basic error module, daily time module, communication inspection module, and current test module. Each module includes data acquisition module, data processing module, and data storage module.

[0022] During operation, threads are used to run the basic error module, daily timing module, and communication inspection module at the same time. After completion, the current test module is operated to increase the operating speed.

[0023] Basic error acquisition module: In the Basic Error Acquisition Module, the number of test items and parameters are first queried using the selected scheme name. This data is then saved in the error parameter array, and the error test operation is then initiated in a loop according to the number of test items. During operation, the 8000 board is reset and the test point parameters, such as status, current phase, current, power factor, frequency, voltage, and phase sequence, are set. Then, after power is applied, the error test is initiated. After the test is completed, the measured data is read, and the average measurement value is calculated and determined by the Basic Error Data Processing Module. After completion, the next test item is initiated, and the data is saved until all items are completed. After the error acquisition function is initiated, the three test functions are simultaneously initiated, along with the daily time acquisition module and the communication test acquisition module, to increase meter inspection speed.

[0024] In the daily timer acquisition module, the test item parameters are first retrieved using the selected scheme name, the data is saved in the daily timer parameter array, and the daily timer test operation is initiated according to the test item. During operation, the daily timer test is started. After the test is completed, the measurement data is read. This operation is repeated three times. The daily timer data processing module calculates and determines the measured value and average value, and the data is saved.

[0025] In the current test module, the number of test items and parameters are first queried using the selected scheme name. This data is then saved in the current test parameter array. Current test operations are then initiated in a loop according to the number of test items. During operation, the meter operates the meter and reads the current data according to the scheme items. The measured data is then checked to see if it meets the upper and lower limits. Once completed, the next test item is initiated until all items are completed and the data is saved.

[0026] In the communication test module, the number of test items and parameters are first queried using the selected solution name. This data is then saved in the communication test parameter array. The communication test is then initiated in a loop according to the number of test items. During operation, the communication test is performed according to the solution items, and the communication test data is then determined to be qualified. Upon completion, the next test item is initiated, and the cycle continues until all items are completed and the data is saved.

[0027] Data processing modules such as Figure 3 As shown: When the basic error data processing module operates, it calculates the average measurement data according to the measurement data and sampling times provided by the basic error acquisition module, and then determines whether the average measurement data meets the measurement requirements and provides the data processing results.

[0028] When the daily timing data processing module operates, it calculates the average measurement data according to the measurement data and sampling times provided by the daily timing acquisition module three times, and then determines whether the three measurement data and the average measurement data meet the measurement requirements, and provides the data processing results.

[0029] When the current test data processing module operates, it determines whether the measurement data provided by the current test acquisition module meets the measurement requirements.

[0030] When the communication test data processing module operates, it determines whether the measurement data provided by the communication test acquisition module meets the measurement requirements.

[0031] Data storage module such as Figure 4 As shown, after the data processing module completes the operation, it performs a data saving operation and uploads the measurement data and results to the production data saving table and the EIP data saving table.

[0032] Query and export modules such as Figure 5 As shown: 1. Query conditions include address, time, task order number, meter inspection data, basic error data, daily time data, communication test data, current test data, and export type; 2. When querying, perform data query operations according to the query conditions entered. When exporting data, export the queried data to the corresponding file according to the selected export type.

[0033] System management modules such as Figure 6 As shown: 1. Set the RS485 communication port and baud rate; 2. Set the platform parameters; 3. Set the operator name and password.

[0034] Software interface modules such as Figure 7 As shown: The software interface is divided into a drop-down menu bar, a tool bar, a work area, and a status bar. The drop-down menu bar includes operator information, communication port information, and instrument parameter information for system management; the tool bar includes functions such as starting and stopping instrument inspection, powering on and off; the work area is used to select plans and download inspection items, as well as select instrument locations and display instrument inspection information; the status bar displays information such as the operator and version.

[0035] Logging modules such as Figure 8 As shown: 1. The log is saved in a TXT file with the time and module name as the file name; 2. Logs primarily record operation and communication logs. Operation logs record port opening and closing status, operational errors, and time. Communication logs include basic error communication logs, daily time communication logs, communication test communication logs, and current test communication logs. The logs store project names, times, and communication commands (sent and returned frames) for subsequent analysis.
