[0030] After introducing the technical terms related to this application, next, the technical solutions provided by this application will be described in detail.

[0031] The embodiment of this application provides a nuclear power data processing system. Referring to Figure 1 As shown, the nuclear power data processing system 100 provided by the embodiment of this application includes a server 110 and a browser 120; the server 110 is communicatively connected to the browser 120;

[0032] Server 110 is used to obtain the real-time point data of the target on-site device from the nuclear power plant DCS system during the process of maintaining an OPC UA communication connection with the nuclear power plant DCS system; perform logical calculations on the real-time point data of the target on-site device based on a logical expression to obtain the real-time data analysis result of the target on-site device; encapsulate the real-time point data and the real-time data analysis result of the target on-site device into a real-time monitoring message and then push it to the browser 120; wherein, the real-time point data of the target on-site device includes the real-time monitoring data of each monitoring point of the target on-site device; the logical expression is an expression that is pre-generated based on different types of operators configured on the browser and is used to represent the operation relationship between each monitoring point.

[0033] Browser 120 is used to parse the real-time monitoring message to obtain the real-time point data and the real-time data analysis result of the target on-site device, and then render and display the real-time point data and the real-time data analysis result of the target on-site device.

[0034] In a possible implementation manner, the server 110 is specifically used to obtain the real-time point data of the subscribed target on-site device from the real-time point data of each on-site device published by the nuclear power plant DCS system.

[0035] In a possible implementation manner, the server 110 is further used to establish an OPC UA communication connection with the nuclear power plant DCS system, and during the process of establishing an OPC UA communication connection with the nuclear power plant DCS system, perform legality verification with the nuclear power plant DCS system based on a dual verification method of a digital certificate and a session key.

[0036] In a possible implementation manner, the server 110 is specifically used to, after encapsulating the real-time point data and the real-time data analysis result of the target on-site device into a real-time monitoring message, generate a push message for the real-time monitoring message, add the push message to the message queue, and push the real-time monitoring message to the browser 129 according to the message arrangement order in the message queue.

[0037] In a possible implementation manner, refer to Figure 1 As shown, the nuclear power data processing system 100 provided by the embodiment of the present application further includes a database 130;

[0038] The server 110 is further used to store the real-time point data of the target on-site device obtained from the nuclear power plant DCS system into the database 130;

[0039] The database 130 is used to store the real-time point data of the target on-site device obtained by the server 110 from the nuclear power plant DCS system.

[0040] In a possible implementation, the server 110 is further configured to obtain historical point data of the target field device from the database 130; perform logical calculation on the historical point data of the target field device based on a logical expression to obtain a historical data analysis result of the target field device; encapsulate the historical point data and the historical data analysis result of the target field device into a historical monitoring message and push it to the browser 120; wherein, the historical point data of the target field device includes historical monitoring data of each monitoring point of the target field device.

[0041] The browser 120 is further configured to parse the historical monitoring message to obtain the historical point data and the historical data analysis result of the target field device, and then render and display the historical point data and the historical data analysis result of the target field device.

[0042] Based on the above embodiments, an embodiment of the present application provides a nuclear power data processing method, which is applied to the server 110 in the above nuclear power data processing system 100 provided by the embodiment of the present application. Refer to Figure 2 As shown, the general process of the nuclear power data processing method provided by the embodiment of the present application is as follows:

[0043] Step 201: During the process of maintaining an OPC UA communication connection with the nuclear power plant DCS system, obtain real-time point data of the target field device from the nuclear power plant DCS system; wherein, the real-time point data of the target field device includes real-time monitoring data of each monitoring point of the target field device.

[0044] In the embodiment of the present application, an OPC UA client is integrated in the server 110 in the nuclear power data processing system 100, and an OPC UA server is integrated in the control device in the nuclear power plant DCS system. An OPC UA communication connection is established between the server 110 and the nuclear power plant DCS system through the OPC UA client and the OPC UA server. To improve the security of nuclear power data, during the process of establishing an OPC UA communication connection between the server 110 and the nuclear power plant DCS system, a dual verification method based on digital certificates and session keys can also be used to perform legality verification with the nuclear power plant DCS system. Specifically, it can adopt but is not limited to the following methods:

[0045] Step 1: The OPC UA client generates a key pair, and uses the private key in the key pair to generate a Certificate Signing Request (CSR) based on website information such as the Fully Qualified Domain Name (FQDN) of the server 110 and key information such as the public key in the key pair, and sends the CSR to the Certificate Authority (CA).

[0046] Step 2: After the CA verifies the website information and key information in the CSR and passes the verification, based on website information such as the fully qualified domain name (FQDN) of Server 110 and key information such as the public key in the key pair, generate a digital certificate for the OPC UA client (hereinafter referred to as the client data certificate), and send the client digital certificate to the OPC UA client;

[0047] Step 3: After receiving the client digital certificate, the OPC UA client installs the client digital certificate into the local certificate storage area of Server 110;

[0048] Step 4: Based on connection configuration information such as the OPC UA port address and legal verification information such as the client digital certificate, the OPC UA client initiates a connection request to the OPC UA server in the control device of the nuclear power plant DCS system;

[0049] Step 5: The OPC UA server verifies the validity of the client digital certificate provided by the OPC UA client and simultaneously returns the server digital certificate to the OPC UA client. The server digital certificate contains the public key and subject of the OPC UA server. The acquisition method of the server digital certificate is similar to that of the above-mentioned client data integer, and the repeated parts will not be elaborated;

[0050] Step 6: After receiving the server digital certificate, the OPC UA client verifies the validity of the server digital certificate. After determining that the server digital certificate is valid, generate a random key for session encryption, encrypt the random key based on the public key provided by the OPC UA server to obtain the encrypted key, and send it to the OPC UA server;

[0051] Step 7: When the OPC UA server determines that the client digital certificate is valid and the random key obtained by decrypting the encrypted key based on its private key is the correct key, it determines that the OPC UA client meets the connection conditions and establishes a communication connection with the OPC UA client, thus completing the OPC UA communication connection between Server 110 and the nuclear power plant DCS system and the dual verification based on digital certificates and session keys; when the above connection conditions are met, Step 8 can be continued; conversely, when the above connection conditions are not met, the connection information can be re-verified. If the connection conditions are met, continue to execute Step 8; if the connection conditions are not met, end the connection. In this way, session key verification can prevent unauthorized access, while digital certificate verification can ensure the identity legality of both communication parties, ensuring that both parties of the communication connection are legal and authorized, thereby improving the security of the communication connection and data exchange.

[0052] Step 8: Obtain the real-time point data of the target on-site device from the nuclear power plant DCS system.

[0053] In specific implementation, the server 110 and the nuclear power plant DCS system perform data exchange in a publish / subscribe (PUB / SUB) mode. The publish / subscribe (PUB / SUB) mode allows the data publisher (i.e., the nuclear power plant DCS system) to send nuclear power data to one or more subscribers (i.e., the server 110), and the subscriber (i.e., the server 110) only receives the nuclear power data it subscribes to. That is, the server 110 only receives the real-time point data of the target on-site device it subscribes to among the real-time point data of each on-site device published by the nuclear power plant DCS system. Among them, the real-time point data push of the target on-site device is based on the publish / subscribe (PUB / SUB) mode, which can be WebSocket or RabbitMQ; the real-time point data of the target on-site device at least includes a nuclear power equipment table, a data point table, and a data collection table; the nuclear power equipment table includes equipment ID, equipment name, equipment type, equipment description, affiliated area, creation time, and update time; the data point table includes data point ID, equipment ID (foreign key associated with the equipment table), data point name, data type (e.g., integer, floating point number, boolean value, etc.), data unit, data description, creation time, and update time; the data collection table includes collection ID, equipment ID (foreign key associated with the equipment table), data point ID (foreign key associated with the data point table), collection time, collection value, and creation time.

[0054] Step 202: Perform data analysis on the real-time point data of the target on-site device based on a logical expression to obtain the real-time data analysis result of the target on-site device; among them, the logical expression is an expression pre-generated based on different types of operators configured on the browser 120 and used to represent the operation relationship between each monitoring point.

[0055] In the embodiments of the present application, the browser 120 is used for the configuration of logical expressions and the display of nuclear power data; the configuration of logical expressions is a key step in the nuclear power data processing method, which allows users to define and configure complex logical expressions, that is, nuclear power data processing rules, based on different types of operators, so that the server 110 can perform data analysis on the real-time point data of the target field device based on different types of logical expressions. The browser 120 provides an intuitive and easy-to-use user interface. Users can configure and edit logical expressions through the user interface to define the processing rules of nuclear power data. The user interface provided by the browser 120 can also present the processed nuclear power data to the user, such as displaying the change trend of nuclear power data, data analysis results (including real-time data analysis results and / or historical data analysis results), and the operating status of the nuclear power plant DCS system, etc. Through the browser, users can clearly understand the situation of nuclear power data, which is convenient for real-time monitoring and analysis. Another advantage of the browser 120 is its cross-platform nature. Users can use different devices such as computers, tablets or mobile phones to access the nuclear power data processing system through the browser 120, without being restricted to a specific workstation, which is convenient for users to operate.

[0056] That is, users can configure different types of operators and logical expressions through the browser 120, so as to provide rich support for operators and logical expressions for the server 110 to process the real-time point data of the target field device, so as to perform different types of operations and comparisons according to requirements. Among them, the operators include but are not limited to arithmetic operators, logical operators, relational operators, etc.; the logical expression is an expression generated according to at least one of the arithmetic operator, logical operator, and relational operator; the arithmetic operators include but are not limited to addition operator (+), subtraction operator (-), multiplication operator (*), division operator ( / ), remainder operator (%), etc.; the logical operator is used to perform logical operations according to the true and false values of the real-time point data, such as combining multiple conditions, including but not limited to and operator (and), or operator (or), not operator (not), etc.; the relational operator is used to compare the relationship between data, including but not limited to greater than operator (>), less than operator (<), greater than or equal to operator (>=), less than or equal to operator (<=), not equal operator (!=), equal to operator (==), etc. In this way, after the server 110 obtains the real-time point data of the target field device from the nuclear power plant DCS system, it can perform data analysis on the real-time point data of the target field device based on different types of logical expressions, so as to obtain the real-time data analysis result of the target field device.

[0057] Step 203: Package the real-time point data and real-time data analysis result of the target field device into a real-time monitoring message, and push the real-time monitoring message to the browser for parsing and rendering display.

[0058] In the embodiment of the present application, after the server 110 analyzes the real-time point data of the target field device based on different types of logical expressions to obtain the real-time data analysis result of the target field device, it can encapsulate the real-time point data and the real-time data analysis result of the target field device into a real-time monitoring message, generate a push message for the real-time monitoring message, add the push message to the message queue, and push the real-time monitoring message to the browser 120 in the order of the messages in the message queue.

[0059] In addition, in the embodiment of the present application, after the server 110 obtains the real-time point data of the target field device from the nuclear power plant DCS system, it can also store the real-time point data of the target field device obtained from the nuclear power plant DCS system in the database, so as to perform data analysis on the historical point data of the target field device according to actual requirements in the future. Specifically, the server 110 can obtain the historical point data of the target field device from the database, perform logical calculations on the historical point data of the target field device based on the logical expression to obtain the historical data analysis result of the target field device, and encapsulate the historical point data and the historical data analysis result of the target field device into a historical monitoring message and then push it to the browser 120 for parsing and rendering display.

[0060] The following further details the nuclear power data processing method provided by the embodiment of the present application. Refer to Figure 3 As shown, the specific process of the nuclear power data processing method provided by the embodiment of the present application is as follows:

[0061] Step 301: The browser 120 obtains the expressions configured by the user based on different types of operators to represent the operation relationships between each monitoring point, and stores the logical expressions configured by the user in the database.

[0062] Step 302: During the process of the server 110 establishing an OPC UA communication connection with the nuclear power plant DCS system, it verifies the connection information with the nuclear power plant DCS system based on the dual verification method of digital certificate and session key.

[0063] Step 303: The server 110 determines whether the connection condition is met; if so, it executes step 305; if not, it executes step 304; where the connection condition is that the client digital certificate provided by the OPC UA client is valid, and the random key provided by the OPC UA client is the correct key.

[0064] Step 304: The server 110 re-verifies the connection information with the nuclear power plant DCS system. If the connection condition is met, it continues to execute step 304; if the connection condition is not met, the connection ends.

[0065] Step 305: Server 110 enables the publish / subscribe mode (i.e., PUB / SUB mode) to receive the real-time point data of the target field device subscribed from the real-time point data of each field device published by the nuclear power plant DCS system. Among them, the PUB component configures information such as the data items to be published, the publishing period, and the data type, and the SUB component configures information such as the data items to be subscribed and the subscription period.

[0066] Step 306: Server 110 stores the real-time point data of the target field device in the database.

[0067] Step 307: Server 110 obtains the logical expression and the point data such as the real-time point data and / or historical point data of the target field device from the database, and performs data analysis on the point data of the target field device based on the logical expression to obtain the data analysis result of the target field device.

[0068] Step 308: Server 110 encapsulates the point data such as the real-time point data and / or historical point data of the target field device and the data analysis result into a monitoring message, generates a push message for the monitoring message, adds the push message to the message queue, and pushes the monitoring message to browser 120 in the order of the message arrangement in the message queue.

[0069] Step 309: After parsing the monitoring message to obtain the point data such as the real-time point data and / or historical point data of the target field device and the data analysis result, browser 120 renders and displays the point data such as the real-time point data and / or historical point data of the target field device and the data analysis result.

[0070] In the embodiments of the present application, nuclear power data exchange is carried out based on the OPC UA protocol, which can realize data exchange between different devices and ensure efficient data transmission. Moreover, the legality verification is carried out based on the dual verification method of session key and digital certificate. It is required that the OPC UA client provides a valid digital certificate and the correct session key, which can prevent unauthorized access or tampering of nuclear power data, help maintain the operation safety of the nuclear power plant, improve the security of nuclear power data, and ensure the confidentiality and integrity of nuclear power data transmission. In addition, by configuring and defining various logical expressions through the browser to process, screen and calculate nuclear power data such as the real-time point data of the target field device, more complex data analysis and processing can be realized. And if it is necessary to change the logical conditions or algorithms, the change of the logical expression can be realized based on the logical expression configuration function on the user interface provided by the browser, thus making the configuration of the logical expression easier and faster, and helping to save time and reduce the error rate. In addition, the publish / subscribe function is introduced in data transmission. Once the point data of the monitoring point of the target field device subscribed by the server 110 changes, the nuclear power plant DCS system can immediately push the real-time point data of the monitoring point of the target field device to the server 110, so as to ensure the real-time and accuracy of nuclear power data, and further enable the operator to obtain updated nuclear power data more quickly, realize real-time monitoring and reaction system status, and thus improve the perception ability of the operation situation of the nuclear power plant.

[0071] Based on the above embodiments, the embodiments of the present application provide a nuclear power data processing device, which is applied to the server 110 in the above nuclear power data processing system provided by the embodiments of the present application. Refer to Figure 4 As shown, the nuclear power data processing device 400 provided by the embodiments of the present application at least includes an OPC UA acquisition module 401, a nuclear power data processing module 402 and a message encapsulation and push module 403 that are connected in sequence;

[0073] The nuclear power data processing module 402 is used to perform logical calculations on the real-time point data of the target on-site device based on a logical expression to obtain the real-time data analysis result of the target on-site device, and send the real-time point data and the real-time data analysis result of the target on-site device to the message encapsulation and push module 403; wherein, the logical expression is an expression pre-generated based on different types of operators configured on the browser and used to represent the operation relationship between each monitoring point.

[0077] In a possible implementation manner, the message encapsulation and push module 403 is specifically used to generate a push message for the real-time monitoring message after encapsulating the real-time point data and the real-time data analysis result of the target on-site device into the real-time monitoring message, add the push message to the message queue, and push the real-time monitoring message according to the message arrangement order in the message queue.

[0078] In a possible implementation manner, the OPC UA acquisition module 401 is further used to store the real-time point data of the target on-site device obtained from the nuclear power plant DCS system into the database.
