[0046] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0047] It should be noted that the flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor do they have to be executed in the order described. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0048] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0049] like Figure 1 As shown, some embodiments of the present invention disclose a method for comparing engineering parameters of a nuclear power unit, comprising the following steps:

[0050] Establish a connection with the engineer station according to the engineer station address and obtain the engineer station authority;

[0051] Start the communication service, use the engineer station authority to establish a connection with the control station under the selected nuclear power unit project, and obtain the online parameters of the control station under the selected nuclear power unit project;

[0052] Classifying the acquired online parameters of the control station of the nuclear power unit project to obtain classified online parameters;

[0053] Obtain offline parameters of nuclear power plant projects;

[0054] The classified online parameters are compared with the offline parameters to obtain parameter comparison results.

[0055] like Figure 2 As shown, in some embodiments, a connection is established with the engineer station according to the engineer station address to obtain the engineer station authority, which also includes: during the first comparison, at least two filled-in engineer station addresses are received. It can be understood that the at least two can be two, three or any number.

[0056] During the first comparison, the filled-in engineer station IP address is accepted, for example, the IP address of SNETA is 128.0.0.88, and the IP address of SNETB is 129.0.0.88. The IP addresses here are only examples and are not intended to limit this application. At least two engineer station IP addresses are filled in for redundancy to avoid the inability to use the engineer station authority to connect to the control station under the selected nuclear power unit project when one engineer station IP address is abnormal.

[0057] In some embodiments, establishing a connection with a control station under a selected nuclear power plant project using the engineer station authority includes:

[0058] According to the path of the nuclear power unit project, use the engineer station authority to establish a connection with the control station under the selected nuclear power unit project. According to the path of the specific nuclear power unit project to be compared, such as the path of the Yangjiang Nuclear Power Unit 1 project: D:\HOLLiAS_MACS\ENG\USER\PY1. The Yangjiang Nuclear Power Unit 1 project and its path here are only examples and are not intended to limit this application.

[0059] In some embodiments, the communication service is started, and a connection is established with the control station of the selected nuclear power unit project using the engineer station authority to obtain online parameters of the control station of the selected nuclear power unit project, which also includes:

[0060] Extract the SDB file of the control station under the selected nuclear power unit project;

[0061] Save the engineer station address and the domain number of the selected nuclear power unit project.

[0062] Specifically, after receiving the engineer station address, the SDB files of each control station under the selected nuclear power unit project are extracted. Clicking the Extract SDB button realizes the extraction of the SDB files of each control station under the selected nuclear power unit project. The SDB file is the symbol table of each control station under the selected nuclear power unit project.

[0063] Save the IP address of the engineer station and the domain number of the selected nuclear power unit project, such as Yangjiang Nuclear Power Unit 1, so that you don't need to reselect the settings later. Click the Save Settings button to save the IP address of the engineer station and the domain number of the selected nuclear power unit project.

[0064] In some embodiments, the communication service is started, and the engineer station authority is used to establish a connection with the control station under the selected nuclear power unit project to obtain the online parameters of the control station under the selected nuclear power unit project. Specifically, after receiving the start service button being clicked, the communication service is started. Starting the communication service is similar to the service for processing and managing input and output requests. After starting, all connected control stations under the selected nuclear power unit project can be displayed.

[0065] like Figure 3 As shown, in some embodiments, the communication service is started, a connection is established with the control station under the selected nuclear power unit project according to the authority of the engineer station, and online parameters of the control station under the selected nuclear power unit project are obtained, including:

[0066] Start the communication service, establish a connection with the control station under the selected nuclear power unit project according to the engineer station authority, and determine whether the connection with the control station is successful. If so, obtain the online parameters of the control station under the selected nuclear power unit project.

[0067] Specifically, the communication service is started, and a connection is established with the control station under the selected nuclear power unit project according to the engineer station authority, and it is determined whether the system counter value of the control station under the selected nuclear power unit project is read. If so, the online parameters of the control station under the selected nuclear power unit project are obtained.

[0068] After starting the communication service, the connection status of all control stations under the selected nuclear power unit project can be displayed, that is, the checkbox of the station connection status is checked and there is a value in the edit box below the checkbox, that is, the system counter value of the control station is read, which proves that the connection with the control station is successful. The system counter represents the life value of the control station. The life value of the control station normally increases and cycles between 0-100. The system counter value can truly represent the status of the control station. Therefore, the system counter value is taken to represent whether the control station is connected. If the system counter value of the control station cannot be read, the connection with the control station fails.

[0069] In some embodiments, obtaining online parameters of a control station under a selected nuclear power plant project includes: obtaining online parameters of all successfully connected control stations under the selected nuclear power plant project according to the address sequence of the control stations.

[0070] like Figure 4 As shown, after the communication service is started, the online parameters are obtained through the interface of the communication service. Specifically, the online parameters are applied for through the interface of the communication service (ReadTagValue). The communication service can apply for online parameters through the Requset method and perform online parameter reading and writing. Finally, the communication service end is responsible for interacting with the control station and requesting the online parameters of the control station through the ReadTagValueEx_RequestProcess method.

[0071] In some embodiments, the acquired online parameters of the control station of the nuclear power unit project are classified to obtain the classified online parameters, including:

[0072] The obtained online parameters of the control station of the nuclear power unit project are put into the online data point table of the database according to a preset order for classification, and the classified online parameters are obtained.

[0073] In some embodiments, the obtained online parameters of the control station of the nuclear power unit project are put into the online data point table of the database according to a preset order for classification, which also includes:

[0074] According to the meaning of the online parameters, the online parameters of the control station of the nuclear power unit project are classified to obtain an online data point table;

[0075] According to the functions of the online parameter point table, different types of data point tables are classified to obtain the online algorithm block data point table.

[0076] In some embodiments, the obtained online parameters of the control station of the nuclear power unit project are put into the online data point table of the database according to a preset order for classification, including:

[0077] The obtained online parameters of the control station of the nuclear power unit project are placed into the corresponding point items of the corresponding online data point table according to a preset order;

[0078] Put different point items into the corresponding online data point table according to the preset order.

[0079] Specifically, according to the address size of the control station under the nuclear power unit project, the online parameters of the control station are obtained in a preset order. In order to facilitate the subsequent comparison of online parameters, all online parameters are classified: ① The online parameters are classified into online data point tables according to the meaning of the parameters. For example, according to the parameter meaning represented by the online parameters, they can be divided into more than one hundred online parameter point tables such as PID, AVO, AVI, DVO, DVI, CMS, NSD, etc.; ② The online parameter point tables are classified into online algorithm block data point tables according to their functions. For example, the more than one hundred online parameter point tables classified in step ① can be divided into but not limited to online IO algorithm block data point tables, online control algorithm block data point tables, etc. according to their respective functions, wherein the online IO algorithm block data point tables Including online data point tables such as AVI, AVO, DVO, DVI, etc., and the online control algorithm block data point table includes online data point tables such as NSP, CMV, NSD, CMP, etc.; ③ In different online data point tables, according to the numerical or alphabetical sorting of the online parameters, the online parameters are placed in the corresponding point items of the corresponding online data point table in the preset order, such as placing the online parameters in the corresponding point items such as the range size, small flow cutting, and output alternative method; ⑤ Sort the different point items by numbers or letters, and place the different point items in the corresponding online data point table in the preset order, for example, place the point items such as the range size, small flow cutting, and output alternative method in the preset order in the PY1ARE001MP online data point table. Finally, the tree diagram after the online parameters are classified is as follows Figure 5 shown.

[0080] In some embodiments, obtaining offline parameters of a nuclear power plant project includes: obtaining a data file under a nuclear power plant project path, the data file including classified offline parameters.

[0081] Select the path of the nuclear power plant project for which offline parameters need to be obtained, that is, the path of the nuclear power plant project selected when obtaining online parameters. For example, if the selected nuclear power plant project is Yangjiang Nuclear Power Unit 1, the specific reading path is: D:\HOLLiAS_MACS\ENG\user\YJ_PY1\HSDB, read the db.dat file, the db.dat file includes the classified offline parameters of the required nuclear power plant project, Yangjiang Nuclear Power Unit 1 and its path here are only examples, and are not intended to limit this application. Specifically, the offline parameters have been classified according to the offline algorithm block data point table, the offline data point table, and the point items of the offline data point table.

[0082] like Figure 6As shown, in some embodiments, the classified online parameters are compared with the offline parameters to obtain parameter comparison results, including:

[0083] Match the online algorithm block data point table with the offline algorithm block data point table;

[0084] Match the online data point table with the offline data point table;

[0085] Matching the point items in the online data point table with the point items in the offline data point table;

[0086] The online parameters of the midpoint items in the online data point table are matched with the offline parameters of the midpoint items in the offline data point table, and the online parameters are compared with the offline parameters to obtain parameter comparison results.

[0087] For example, if a certain parameter of the range size point item in the AVI data point table in the IO algorithm block data point table is needed, specifically, first make the online IO algorithm block data point table correspond to the offline IO algorithm block data point table, then make the online AVI data point table correspond to the offline AVI data point table, then make the range size point item in the online AVI data point table correspond to the range size point item in the offline AVI data point table, finally make the online parameters to be compared correspond to the offline parameters, and compare the online parameters with the offline parameters to obtain the parameter comparison results.

[0088] After the online parameters and offline parameters are compared, the parameter comparison results will be recorded in the selected result storage path and saved in the form of an EXCEL table. Figure 7 As shown in the table, the total table records the comparison results and total differences between online and offline parameters of all databases, such as Figure 8 As shown, the other tables are the comparison results and specific differences between the online parameters and offline parameters of each database.

[0089] In some embodiments, comparing the classified online parameters with the offline parameters to obtain parameter comparison results includes: comparing the classified online parameters with the offline parameters, and placing the obtained parameter comparison results into the selected storage path.

[0090] Specifically, after receiving the comparison button being clicked, the online parameters and offline parameters are compared, and the results are generated in the selected storage path. The storage path of the comparison results can be arbitrarily selected to facilitate the search of results, such as C:\Users\1\Desktop\. The path here is only an example and is not intended to limit this application.
