[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In order to optimize and reduce the workload of operators in the main control room of a nuclear power plant, minimize the possible deviations caused by manual recording and calculation, and optimize the energy allocation of operators in the main control room, the present invention provides a method for automatically capturing and differentiating test data of a DCS platform of a nuclear power unit. The method automatically obtains data from a DCS server, and automatically calculates and determines the data according to preset calculation rules, thereby significantly improving the work efficiency of operators in the main control room, ensuring the immediacy and reliability of monitoring work, and obtaining great benefits with minimal energy.

[0046] Specifically, refer to Figure 1 , Figure 1 The present invention provides a flowchart of a preferred embodiment of the method for automatically capturing and distinguishing test data of a nuclear power unit DCS platform.

[0047] like Figure 1 As shown, the method for automatically capturing and distinguishing test data of the nuclear power unit DCS platform includes the following steps:

[0048] Step S101: Obtain data description information of the data to be processed.

[0049] In the embodiment of the present invention, before executing step S101, the following steps are first performed: determining whether a data capture instruction is received; if so, performing the step of obtaining data description information of the data to be processed. Specifically, in actual application, when the operator of the main control room needs to capture the test data of the DCS platform, the operator of the main control room clicks the data capture control key in the KIC screen. At this time, the system receives the data capture instruction, determines the data description information of the data to be processed according to the data capture instruction, and obtains the data description information.

[0050] Step S102: Capture the data to be processed from the DCS platform according to the data description information of the data to be processed.

[0051] In the embodiment of the present invention, the data description information includes: DCS data point name.

[0052] In some embodiments, capturing the data to be processed from the DCS platform according to the data description information of the data to be processed includes: determining the DCS data point name of the data to be processed according to the data description information of the data to be processed; and reading data in the DCS platform according to the DCS data point name to obtain the data to be processed.

[0053] Take the No. 1 steam generator water level meter as an example, the DCS data point name format is: ARE010MN. The standard format is: ! R PY3ARE010MN.AV; % F6.3 Other data are similar, and only the device name needs to be modified adaptively. It should be noted that the data to be captured in different modes is different. Different modes have a table template. Figure 2 The table template in mode 1 is shown. Each table template stores the data point name of the data to be captured. Therefore, when receiving the data capture instruction triggered by the operator in the main control room, the system can directly read the corresponding DCS data point name from each table template according to the data capture instruction, and then automatically capture the corresponding test data from the DCS server (i.e., DCS platform) according to the read DCS data point name, and write the read data into the position of the corresponding measured value in the table template to complete the automatic capture of DCS test data.

[0054] Step S103: pre-process the data to be processed to obtain pre-processed data.

[0055] In order to improve the accuracy of captured data, the present invention also needs to preprocess the captured data to be processed, that is, preprocess the data to be processed to obtain the preprocessed data, including: cleaning, deduplication and abnormal data processing of the data to be processed to obtain the preprocessed data.

[0056] Step S104: Calculate the preprocessed data according to preset calculation rules to obtain calculation results.

[0057] In the embodiment of the present invention, the preset calculation rule includes: a preset calculation formula or a preset calculation function.

[0058] In some embodiments, calculating the preprocessed data according to a preset calculation rule to obtain a calculation result includes: calculating the preprocessed data according to a preset calculation formula or a preset calculation function to obtain a calculation result.

[0059] Specifically, different test data have different calculation formulas or calculation functions. Therefore, after capturing the test data, automatic calculation can be performed according to the preset calculation formula or preset calculation function corresponding to the test data to obtain the corresponding calculation result.

[0060] For example, the total flow rate of the RCP system (one-loop coolant system) is used for explanation. Figure 3 As shown in the figure, the flow of the RCP system involves the readings of multiple loop instruments of 3RCP025MD, 3RCP026MD, 3RCP027MD, 3RCP040MD, 3RCP041MD, 3RCP042MD, 3RCP052MD, 3RCP053MD, and 3RCP054MD. Therefore, the system needs to automatically capture the measurement data of these loop instruments, obtain the flow value of each instrument, and then calculate the average flow of each loop, and finally calculate the total flow of RCP. The specific calculation formula is:

[0061] V RCP总 =(V R25 +V R26 +V R27 ) / 3+(V R40 +V R41 +V R42 ) / 3+(V R52 +V R53 +V R54 )

[0062] / 3;

[0063] In the above formula, V RCP总 represents the total flow rate of the RCP system, V R25 Indicates the measured value of 3RCP025MD, V R26 Indicates the measured value of 3RCP026MD, V R27 Indicates the measured value of 3RCP027MD, V R40 Measured value of 3RCP040MD, V R41 Indicates the measured value of 3RCP041MD, V R42 Indicates the measured value of 3RCP042MD, V R52 Indicates the measured value of 3RCP052MD, V R53 Indicates the measured value of 3RCP053MD, VR54 Indicates the measured values ​​of 3RCP054MD.

[0064] Step S105: Compare the calculation result with the acceptance criteria to obtain a determination result.

[0065] Specifically, after the calculation result is obtained in step S104, the calculation result is compared with the acceptance criteria to obtain the judgment result, thereby completing the automatic judgment of the test data. For example, taking the total flow of the aforementioned RCP system as an example, when the total flow of the RCP is calculated to be 73070.93333m 3 / h, and then compare this value with the acceptance criteria (i.e. 68520m 3 / h) compared, obviously, 73070.93333m 3 / h>68520m 3 / h, therefore, the judgment result is normal, that is, "yes" in the data table.

[0066] Step S106: Generate a data table based on the data to be processed, the calculation results and the determination results.

[0067] In an embodiment of the present invention, generating a data table based on the data to be processed, the calculation results and the determination results includes: obtaining a table template; importing the data to be processed, the calculation results and the determination results into the table template to generate a data table.

[0068] Specifically, after the data to be processed is captured and the test data calculation and judgment are completed, the data to be processed, the calculation results of the test data and the judgment results are written into the table template, that is, Figure 2 The data table can be generated in the corresponding position shown.

[0069] Furthermore, in an embodiment of the present invention, the method for automatically capturing and distinguishing test data of a nuclear power unit DCS platform further includes: determining whether a report printing instruction is received; and if so, printing out a data table according to the report printing instruction.

[0070] Specifically, when a report printing instruction is received, the system can automatically print a data table according to the report printing instruction. Figure 4 shown.

[0071] refer to Figure 5 , Figure 5 The invention provides a device for automatically capturing and distinguishing test data of a nuclear power unit DCS platform. The device can be used to implement the method for automatically capturing and distinguishing test data of a nuclear power unit DCS platform disclosed in the embodiment of the invention.

[0074] The data capture unit 502 is used to capture the data to be processed from the DCS platform according to the data description information of the data to be processed;

[0076] The data calculation unit 504 is used to calculate the pre-processed data according to a preset calculation rule to obtain a calculation result;

[0077] The comparison and determination unit 505 is used to compare and determine the calculation result with the acceptance criteria to obtain a determination result;

[0078] The table generating unit 506 is used to generate a data table based on the data to be processed, the calculation results and the determination results.

[0079] Specifically, the specific coordination operation process between the various units in the nuclear power unit DCS platform test data automatic capture and identification device here can refer to the above-mentioned nuclear power unit DCS platform test data automatic capture and identification method, which will not be repeated here.

[0080] In actual application, the operator in the main control room only needs to click the data capture control button on the panel, and the system will read the corresponding DCS data point name from each table template, and then automatically capture the test data from the DCS server according to the read DCS data point name, and calculate according to the preset calculation formula or related function, and then compare the calculation result with the acceptance criteria and give the final judgment result. If the test data is unqualified, it will be highlighted to remind the operator to respond. When the print instruction is received, the data table will be printed out.

[0081] Through the present invention, the time for the main control room operator to execute the program is shortened from the original 1 hour to less than 10 minutes. A nuclear power unit can save 1833 hours for the main control room operator in a year, achieving the purpose of greatly improving quality and efficiency. It not only significantly improves work efficiency, reduces work human risk, optimizes the energy allocation of the main control operator, and saves production costs.
