That is, the functional entities can 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] As shown in Figure 1 Some embodiments of the present application disclose a method for comparing engineering parameters of a nuclear power unit, comprising the following steps:

[0050] According to the address of the engineer station, a connection is established with the engineer station to obtain the authority of the engineer station;

[0051] A communication service is started, and the authority of the engineer station is used to establish a connection with the control station under the selected nuclear power unit engineering to obtain the online parameters of the control station under the selected nuclear power unit engineering;

[0052] The obtained online parameters of the control station under the nuclear power unit engineering are classified to obtain classified online parameters;

[0053] Offline parameters of the nuclear power unit engineering are obtained;

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

[0055] As shown in Figure 2 In some embodiments, according to the address of the engineer station, a connection is established with the engineer station to obtain the authority of the engineer station, and before that, when first comparing, at least two filled-in engineer station addresses are received. Understandably, the at least two can be two, three, or any number.

[0056] When first comparing, the filled-in engineer station IP addresses are 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 do not limit the present application. Among them, at least two engineer station IP addresses are filled in redundancy, so that when one engineer station IP address is abnormal, the control station under the selected nuclear power unit engineering cannot be connected using the authority of the engineer station.

[0057] In some embodiments, the authority of the engineer station is used to establish a connection with the control station under the selected nuclear power unit engineering, comprising:

[0058] According to the path of the nuclear power unit engineering, the authority of the engineer station is used to establish a connection with the control station under the selected nuclear power unit engineering. According to the path of the specific nuclear power unit engineering to be compared, for example, the path of Yangjiang Nuclear Power Unit 1 engineering is: D:\HOLLiAS_MACS\ENG\USER\PY1. The Yangjiang Nuclear Power Unit 1 engineering and its path here are only examples and do not limit the present application.

[0059] In some embodiments, the communication service is started, the authority of the engineer station is used to establish a connection with the control station under the selected nuclear power unit engineering, and the online parameters of the control station under the selected nuclear power unit engineering are obtained, and before that,

[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 extracts 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 engineer's workstation IP address and the domain number of the selected nuclear power unit project, such as Yangjiang Nuclear Power Plant Unit 1. This will eliminate the need to reselect and configure it later. Clicking the "Save Settings" button saves the engineer's workstation IP address and the domain number of the selected nuclear power unit project.

[0064] In some embodiments, a communication service is initiated to establish a connection with the control station under the selected nuclear power unit project using the engineer station's permissions, and to obtain the online parameters of the control station under the selected nuclear power unit project. Specifically, after the "Start Service" button is clicked, the communication service is initiated. The communication service is similar to a service that processes and manages input and output requests. After initiation, all connected control stations under the selected nuclear power unit project can be displayed.

[0065] like Figure 3 As shown, in some embodiments, a communication service is initiated, and a connection is established with the control station under the selected nuclear power unit project according to the engineer's station permissions to obtain the online parameters of the control station under the selected nuclear power unit project, 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's permissions, determine whether the connection with the control station is successful, and if so, obtain the online parameters of the control station under the selected nuclear power unit project.

[0067] Specifically, the communication service is activated, and a connection is established with the control station under the selected nuclear power unit project according to the engineer station's permissions. It is then determined whether the system counter value of the control station under the selected nuclear power unit project has been 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 states of all control stations under the selected nuclear power unit project can be displayed, that is, the check boxes of the station connection states are checked and there are values in the edit boxes below the check boxes, which means that the system counter values of the control stations are read, proving that the connection with the control stations is successful. The system counter represents the health of the control station, and the health of the control station normally increases in a cycle between 0 and 100. The system counter value can truly represent the state of the control station, so 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, the online parameters of the control stations under the selected nuclear power unit project are obtained, including: sequentially obtaining the online parameters of all the control stations successfully connected under the selected nuclear power unit project according to the addresses of the control stations.

[0070] As shown in Figure 4 After starting the communication service, the online parameters are obtained through the interface of the communication service. Specifically, the online parameters are applied through the interface (ReadTagValue) of the communication service. The communication service can apply the online parameters through the Requset method to read and write the online parameters. Finally, the communication service end is responsible for interacting with the control station, and the online parameters of the control station are requested through the ReadTagValueEx_RequestProcess method.

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

[0072] The obtained online parameters of the control stations under the nuclear power unit project are classified according to a preset order and placed in the online data point table of the database to obtain the classified online parameters.

[0073] In some embodiments, the obtained online parameters of the control stations under the nuclear power unit project are classified according to a preset order and placed in the online data point table of the database, and further including:

[0074] According to the parameter meaning of the online parameters, the obtained online parameters of the control stations under the nuclear power unit project are classified to obtain the online data point table.

[0075] According to the function 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 stations under the nuclear power unit project are classified according to a preset order and placed in the online data point table of the database, including:

[0077] The obtained online parameters of the control stations under the nuclear power unit project are placed in the corresponding point items of the corresponding online data point table according to the preset order.

[0078] According to the preset order, the different point items are put into the corresponding online data point table.

[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, and for the convenience of subsequent comparison of the online parameters, all the online parameters are classified: ① the online parameters are classified into online data point tables according to the parameter meanings, for example, more than one hundred online parameter point tables can be classified into PID, AVO, AVI, DVO, DVI, CMS, NSD and the like according to the parameter meanings represented by the online parameters; ② the online parameter point tables are classified into online algorithm block data point tables according to the functions, for example, the more than one hundred online parameter point tables classified in step ① can be classified into, but not limited to, online IO algorithm block data point tables, online control algorithm block data point tables and the like according to the respective functions, wherein the online IO algorithm block data point tables include AVI, AVO, DVO, DVI and the like, and the online control algorithm block data point tables include NSP, CMV, NSD, CMP and the like; ③ according to the numerical or alphabetical order of the online parameters, the online parameters are put into the corresponding point items of the corresponding online data point table in a preset order, for example, the online parameters are put into the point items such as the range size, the small flow cut-off and the output replacement mode; ⑤ according to the numerical or alphabetical order, the different point items are put into the corresponding online data point table in a preset order, for example, the point items such as the range size, the small flow cut-off and the output replacement mode are put into the PY1ARE001MP online data point table in a preset order. The tree diagram after classification of the online parameters is shown in Figure 5 .

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

[0081] The path of the nuclear power unit project for which the offline parameters are needed to be obtained is selected, that is, the path of the nuclear power unit project selected when the online parameters are obtained, for example, the selected nuclear power unit project is Yangjiang Nuclear Power Unit 1, and the specific reading path is D:\HOLLiAS_MACS\ENG\user\YJ_PY1\HSDB, the db.dat file is read, and the db.dat file includes the classified offline parameters of the nuclear power unit project needed, and the Yangjiang Nuclear Power Unit 1 and the path thereof herein are only examples and do not limit the present 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] As shown in Figure 6As shown, in some embodiments, the classified online parameters are compared with the offline parameters to obtain parameter comparison results, including:

[0083] The online algorithm block data point table and the offline algorithm block data point table are corresponded;

[0084] The online data point table and the offline data point table are corresponded;

[0085] The point items of the online data point table and the point items of the offline data point table are corresponded;

[0086] The online parameters of the point items in the online data point table are corresponded with the offline parameters of the point 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, a certain parameter of the range size point item in the AVI data point table in the IO algorithm block data point table needs to be compared. Specifically, the online IO algorithm block data point table and the offline IO algorithm block data point table are corresponded first, then the online AVI data point table and the offline AVI data point table are corresponded, the range size point item in the online AVI data point table and the range size point item in the offline AVI data point table are corresponded, and finally the online parameters and the offline parameters that need to be compared are corresponded, and the online parameters are compared with the offline parameters to obtain parameter comparison results.

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

[0089] In some embodiments, the classified online parameters are compared with the offline parameters to obtain parameter comparison results, including: the classified online parameters are compared with the offline parameters, and the obtained parameter comparison results are put into the selected storage path.

[0090] Specifically, after receiving that the comparison button is clicked, the comparison of the online parameters and the offline parameters is started, and the results are generated in the selected storage path. The selected result storage path can be arbitrarily selected to store the comparison results, which is convenient for finding the results, for example, C:\Users\1\Desktop\, the path here is only an example and does not limit the present application.
