[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0040] In response to the above problems, this application provides a nuclear power control station periodic test method, see Figure 1 , the method may include:

[0041] Step S101: obtaining an intelligent data table, wherein the data information in the intelligent data table includes a target variable name, a target variable offset, a target variable length, and a target variable type of each target variable.

[0042] In the real-time scenario of this solution, designers edit a smart data table on an engineering station and send it to the system and controller using this method. The controller and the control station have a one-to-one correspondence. The smart data table sent to the controller includes the target variable's address and length; the smart data table sent to the system using this method includes the target variable's name, offset, length, and type.

[0043] Step S102: obtaining an online value of a target variable of a control station output by a controller based on a preset frequency, and an operation result of the control station based on the online value of the target variable, which is recorded as a first operation result.

[0044] After obtaining the smart data table, the controller collects the online value of the target variable in the smart data table based on the variable address and variable length of the target variable in the smart data table, and the operation result of the control station based on the online value of the target variable based on the preset frequency, and uses the operation result as the first operation result. The online value of the target variable and the corresponding first operation result are packaged and sent to the system to which the present method is applied.

[0045] In this step, the controller automatically constructs test cases based on the online values ​​of the target variables of each control station and the output results of the control station based on the online values ​​of the target variables in real time. At this time, there is no need for users to manually write test cases, and the real-time performance is high.

[0046] Step S103: saving the online value of the target variable to a local file according to the smart data table.

[0047] After obtaining the online value of the target variable sent by the controller, this step saves the online value of the target variable in a local file based on the configuration of each target variable in the smart data table (target variable name, target variable offset, target variable length and target variable type).

[0048] Step S104: running the target algorithm program according to the locally stored online value of the target variable to obtain a calculation result, which is recorded as a second calculation result, wherein the target algorithm program is equivalent to the algorithm program run by the processing system of the control station.

[0049] After the online value of the target variable is obtained, the online value of the target variable is used as input data of the target algorithm program, and the target algorithm program is run, and the operation result of the target algorithm program is used as the second operation result.

[0050] Step S105: Output the comparison result of the output variables in the first operation result and the second operation result.

[0051] During the operation and maintenance of a nuclear power control station, after obtaining the first and second computation results, a key step is to compare the output variables of these two results to ensure consistency. This comparison mechanism is an important basis for assessing the reliability of the control system: if the output variables are consistent, it indicates that the control system in the control station is operating reliably and normally; conversely, if the output variables are inconsistent, it may indicate an abnormality or potential failure in the control system.

[0052] In order to further improve the efficiency and transparency of operation and maintenance, this solution also proposes the function of automatically generating test reports based on comparison results. This report, named T2 test report, is designed to visually display the experimental results, so that operation and maintenance personnel can quickly understand the system status. The T2 test focuses particularly on verifying the correctness of the protection logic function. Through intuitive data comparison and analysis, it can quickly identify potential logical errors or system inconsistencies, providing strong support for subsequent troubleshooting and maintenance work. By comparing the output variables of the calculation results and generating T2 test reports, this solution not only enhances the accuracy and efficiency of nuclear power control station operation and maintenance, but also improves information transparency through visualization, providing a solid guarantee for the safe operation and maintenance of nuclear power.

[0053] As can be seen from the above scheme, the present application proposes a nuclear power control station operation and maintenance test scheme, the core of which is to automatically obtain the online value of the control station target variable and its corresponding operation result through the controller. Subsequently, the online value is sent to the target algorithm program equivalent to the control station processing system operation algorithm program. Importantly, this process does not require the user to manually write test cases, but directly uses the actual target variables on the control station side as the test basis. The target algorithm program generates operation results based on these online values, compares them with the operation results of the control station, and finally outputs the comparison results. This scheme significantly simplifies the testing process and maintenance methods. Due to the use of automation, the system can automatically test each control station without manual intervention, thereby greatly improving the testing efficiency. In addition, since the test cases are directly derived from the actual operation data of the control station, the accuracy of the test and the advantage of being close to the actual operation scenario are ensured.

[0054] In summary, this application realizes an automated testing process without the need for users to write test cases by automatically acquiring online values ​​and using equivalent target algorithm programs for comparison. This not only simplifies the maintenance method, but also speeds up the testing process, providing strong support for the safe and efficient operation and maintenance of nuclear power control stations.

[0055] In the technical solution disclosed in this embodiment, to facilitate subsequent data collation, detailed information about each output variable in the first and second operation results can be stored in a database. When storing the output variables, the time stamp of each target variable can be used as a key to sequentially store the detailed information about each target variable. Specifically, to effectively store the detailed information about each output variable in the first and second operation results in the database, a database table can be pre-designed. This table can contain configurations that can be configured based on the detailed information about the target variable. For example, the detailed information can include the target variable's ID, name, type, length, time stamp, and real-time value. In this case, the database table can include fields such as ID (serving as the primary key, auto-incrementing to ensure uniqueness), type (an enumerated type used to distinguish between the first and second operations), target variable name (storing the name of the output variable), time stamp (using a timestamp or datetime type to record the time stamp of the output variable), length, real-time value, and other information (using a text or JSON type to store serialized detailed information about the output variable). During the storage process, the output variables in each operation result are traversed, the name, time stamp, and detailed information of each variable are extracted, and database records are constructed accordingly. These records are then inserted into the database table in sequence. To ensure the temporal sequence of data, the output variables can be sorted by time stamp before insertion. The database not only stores detailed information on the calculation results, but also provides the ability to retrieve output variables in chronological order through the time stamp field, making data query and analysis more convenient.

[0056] In the technical solution disclosed in this embodiment, the first operation result and the second operation result can be stored in a Redis database, and the output variables in the first operation result and the second operation result can be compared in real time through the Redis database. Then, the name, type, length, and real-time value of the output variable can be stored in the Redis database using the time stamp of the output variable as a keyword.

[0057] In this embodiment, there can be multiple controllers, each corresponding to a control station. Each controller can collect the online value of the target variable of the control system of its corresponding control station, as well as the operating result of the control system based on the online value of the target variable, and then send the online value of the target variable and the operating result to the system applying this method. Assuming that the number of controllers is N, in the above scheme, when obtaining the online value of the target variable of the control station output by the controller based on a preset frequency, and the operating result of the control station based on the online value of the target variable, it is specifically configured to: obtain the online value of the target variable of the control station corresponding to each controller output based on the preset frequency, and the operating result of the control station based on the online value of the target variable. In this case, outputting the comparison result of the output variable in the first operation result and the second operation result includes: sequentially outputting the comparison result of the first operation result output by the N controllers with the output variable in the second operation result corresponding to the online value of the target variable corresponding to the first operation result. That is, the comparison result of the output variable in the first output result corresponding to the online value of each group of target variables and the second output result is sequentially obtained, and each group of target variables refers to a combination of target variables belonging to the same control station. Through this approach, the solution can comprehensively monitor and optimize the control effects of multiple control stations, identify control stations with precise control and those that need improvement, and thus provide key support for improving the stability and operational efficiency of the entire system.

[0058] In the technical solution disclosed in this embodiment, the processing systems of the control stations corresponding to the N controllers can be the same or different. Because different types of processing systems require running different target algorithm programs, this application introduces a key step to determine the target algorithm program that matches a specific target variable before running the target algorithm program based on the online value of the locally stored target variable.

[0059] To achieve this goal, the present application pre-establishes a correspondence between control stations and target algorithm programs. This correspondence ensures that each system type's control station has a unique corresponding target algorithm program. In actual operation, the control station's identity is first embedded in the first run result. Subsequently, after obtaining the first run result, it is parsed to extract the control station's identity. Using this identity, the target algorithm program that matches the control station can be accurately found from the preset correspondence, and subsequent algorithm operation and result analysis can be performed accordingly. This method not only improves the flexibility and adaptability of the system, but also ensures the accuracy and efficiency of algorithm operation.
