[0051] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0052] In the present application, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0053] As can be seen from the background art, in the prior art, since the communication station cannot obtain various types, multiple cycles, and customizable type data sent by multiple control stations, it is impossible to meet the fast traversal and fast analysis of the control station data by other offline data analysis software, resulting in low processing efficiency of the control station data. Therefore, how to improve the processing efficiency of the control station data is an urgent problem to be solved in the present application.

[0054] To solve the above problems, the present application discloses a data processing method, device and related equipment based on a nuclear power instrument control system, which acquires various types, multi-cycle, and customizable type control station data of multiple control stations in the nuclear power instrument control system transmitted on the basis of the Ethernet physical layer and data link layer. Since the customizable type refers to one-dimensional arrays or multi-dimensional arrays of the same type, or one-dimensional arrays or multi-dimensional arrays of different types, this solution supports the parsing of customizable type data and realizes the storage of the acquired control station data of multiple control stations by category and by cycle, so as to meet the requirements of other offline data analysis software for the quick traversal and fast reading analysis of control station data, and improve the processing efficiency of the control station data of the nuclear power instrument control system. The specific implementation manner will be specifically described through the following embodiments.

[0055] Refer to Figure 1 As shown, a data processing method based on a nuclear power instrument control system disclosed in an embodiment of the present application mainly includes the following steps:

[0056] S101: Acquire the control station data of multiple control stations in the nuclear power instrument control system; wherein, the control station data of multiple control stations is stored through a pre-designed message queue.

[0057] In S101, the control station data of multiple control stations in the nuclear power instrument control system is collected by capturing network data packets and a network packet capture library (NPCAP); wherein, the control station data at least includes health parameter data, periodic test data, and forced table data.

[0058] Among them, the health parameter data is data representing the operating state of the control station, such as the percentage of the central processing unit (CPU), memory, and storage used, etc.

[0059] The periodic test data is, for example, the input and output data of the running algorithm in the controller.

[0060] The forced table data represents the value of the forced point.

[0061] The specific design process of the message queue is as shown in A1 - A3.

[0062] A1: Define the message queue structure; wherein, the structure at least includes a condition variable, a read lock, and a write lock;

[0063] A2: Initialize the condition variable, read lock, and write lock in the message queue structure.

[0064] Among them, initializing the condition variable, read lock, and write lock in the message queue structure means allocating the memory space of the message queue structure and initializing the read-write lock and the condition variable.

[0065] Read locks and write locks are mechanisms for protecting shared resources. Read locks and write locks are used to protect shared resources. Multiple read threads can execute concurrently, while write threads need to exclusively occupy the resources, and other write and read accesses to the shared resources need to wait.

[0066] Condition variables provide a mechanism for inter-thread communication, allowing one thread to wait for another thread to meet a certain condition before continuing to execute.

[0067] A3: Design a message queue for data synchronization through initialized condition variables, read locks, and write locks.

[0068] In A3, a message queue for data synchronization is designed by combining condition variables, read locks, and write locks.

[0069] The message queue uses a double-ended queue for data storage, provides interfaces for accessing and configuring the queue capacity, and uses read-write locks to control the invocation of the access interfaces. This queue is used to store data from multiple control stations in memory.

[0070] S102: Parse the control station data according to the data address point table and type comparison table obtained from configuration to obtain the parsing result.

[0071] The prerequisite for this solution is to use the configuration software of the engineer station for configuration, configuring one-dimensional arrays or multi-dimensional arrays of the same type, one-dimensional arrays or multi-dimensional arrays of different types, where both the data type and the number of arrays can be customized. Compile one-dimensional arrays or multi-dimensional arrays of the same type, as well as one-dimensional arrays or multi-dimensional data of different types, and generate a data address point table and a data type comparison table after compilation.

[0072] The specific process of parsing the control station data according to the data address point table and type comparison table obtained from configuration to obtain the parsing result is shown in B1 - B3.

[0073] B1: Through the configuration software, configure one-dimensional arrays or multi-dimensional arrays of the same type, as well as one-dimensional arrays or multi-dimensional data of different types.

[0074] Among them, the configuration software of the engineer station needs to support the configuration of custom type data. The custom type data includes one-dimensional or multi-dimensional arrays, and the data types in the arrays include but are not limited to basic data types such as char, bool, short, int, long, float, double, unsigned types, etc.

[0075] B2: Compile and install one-dimensional arrays or multi-dimensional arrays of the same type, as well as one-dimensional arrays or multi-dimensional data of different types, to obtain a data address point table and a type comparison table.

[0076] Use the engineer station configuration software to configure the project. When configuring variables, configure one-dimensional or multi-dimensional arrays. After the project is compiled by the configuration software, a data address point table and a type comparison table will be generated. The data address point table contains at least information such as point name, point type, point offset, point length, and point initial value. The type comparison table contains at least point type name, basic type, length, offset, initial value, number of variables, etc.

[0077] B3: Parse the control station data according to the data address point table and the type comparison table to obtain the parsing result.

[0078] According to the parsing tool, the data address point table and the type comparison table, parse the control station data to obtain the parsing results of data of different types and different periods. The parsing results include a log file and a binary file.

[0079] S103: Create respective corresponding storage folders according to different types of data in the parsing result, and store the data of different types in corresponding periods in the storage folders; among them, the name of the storage folder is determined by encrypting at least the data type and the timestamp value together.

[0080] Among them, the name of the storage folder is determined by the value obtained by encrypting the data type, the timestamp, the time interval, etc. together.

[0081] According to different types of data in the parsing result, create storage folders for different types of data. The name of the storage folder is the ciphertext obtained by encrypting a fixed string using an encryption algorithm. The fixed string contains classification information such as data type (such as periodic test data, health data, forced data, etc.), timestamp or time interval. For example, using the MD5 encryption algorithm, the fixed string format is "data type + timestamp".

[0082] Specifically, the process of creating respective corresponding storage folders according to different types of data in the parsing result and storing the data of different types in corresponding periods in the storage folders is shown in C1 - C4.

[0083] C1: Obtain the periodic test data, health data, and forced data in the parsing result.

[0084] C2: Create a first storage folder corresponding to the periodic test data, a second storage folder corresponding to the health data, and a third storage folder corresponding to the forced data.

[0085] C3: Combine the data type of the periodic test data and the first timestamp value into a first string and encrypt it.

[0086] For example, the regular test data is stored in the first storage folder D: / (under MD5("Test + timestamp")). The data files are stored by time. For example, if the regular test data is millisecond-level data, such as millisecond-cycle data, the storage path is: D: / MD5("Test + yearmonthdayhourminute second") / yearmonthdayhourminute second millisecond.bin.

[0087] C4: Combine the data type of the health data and the second timestamp value into a second string and encrypt it. For example, according to the data type, the health data is stored in the second storage folder D: / MD5("Health + timestamp"). If the health data is second-level data, such as second-cycle data, the storage path is: D: / MD5("Health + yearmonthdayhour") / yearmonthdayhour second.bin.

[0088] C5: Combine the data type of the forced data and the third timestamp value into a third string and encrypt it.

[0089] For example, the forced data is stored in the third storage folder D: / MD5("Force + timestamp"). If the forced data is minute-level data, such as minute-cycle data, the storage path is: D: / MD5("Force + yearmonthdayhour") / yearmonthdayhour minute.bin.

[0090] It can be seen from the above scheme that the millisecond-level data is stored in a folder named after the MD5 encryption value of the data type + second as the timestamp. The advantage is that the number of files stored in the second-level folder is limited. When other systems parse the data, they can quickly traverse and parse the files. The second-level and minute-level data are both stored in this way, which is convenient for other offline software to quickly traverse the files in the folder and parse the data.

[0091] The bin folder stores the ciphertext, which is divided into three parts. The first part includes the encrypted data length a of the basic data, the length b of the complex data type, and the encryption algorithm. The values of a and b are randomly generated each time; the second part is the basic type data (data types such as char, bool, short, int, long, float, double, unsigned types, etc.); the third part is the complex type data (one-dimensional arrays or multi-dimensional arrays of the same type, one-dimensional arrays or multi-dimensional arrays of different types). Each piece of complex type data is stored in the format of offset, length, and value. The encrypted data with random lengths can ensure that the data is not easily cracked and parsed by other software during storage, and can ensure the security of the data.

[0092] To facilitate the understanding of the process of data processing based on the nuclear power I&C system, combined with Figure 2 it is described as follows:

[0093] Figure 2Among them, the engineer station configuration software with the function of supporting custom types is used for configuration. When configuring variables, one-dimensional or multi-dimensional arrays are configured, and after compilation and downloading, a data address point table and a type comparison table are generated;

[0094] When the control station uploads these data, such as health parameter data (data representing the running state of the control station, such as the percentage of CPU, memory, and storage usage), periodic test data (such as the input and output data of the running algorithm in the controller), and forced table data (the values of forced points), at different periods, the running data parser of this solution parses the data address point table and the data comparison table;

[0095] Start using the NPCAP library to collect data. When it is determined to be health parameter data, the control station data is encrypted according to the above encryption scheme, and the data is stored in the D: / MD5("Test + year-month-day hour:minute:second") folder. When it is determined to be periodic test data, the data is encrypted and stored in the D: / MD5("Health + year-month-day hour:minute") folder. When it is determined to be forced table data, the data is encrypted and stored in the D: / MD5("Force + year-month-day hour") folder.

[0096] This solution provides a method for collecting, parsing, and storing multi-control station data. This method can obtain various types, multi-period, and customizable type data from multiple control stations. The custom types in this application refer to one-dimensional arrays or multi-dimensional arrays of the same type, one-dimensional arrays or multi-dimensional arrays of different types. The data type and the number of arrays are determined according to the actual situation, and can be configured at the engineer station. After compilation, a data type point table is generated, including a basic data type point table and a complex data type point table. The data is parsed according to the point table. After parsing, according to the data type, it is stored in a folder named with the MD5 value of the data type + timestamp and other classification information for other systems or platforms to parse.

[0097] This solution involves the collection, parsing, and storage of various types, multi-period, and customizable type data of multiple control stations, and belongs to the field of industrial control. This solution can be used for the collection, parsing, and storage of data of multiple control stations in the field of industrial control. In the field of industrial control, multiple control stations will interact with other systems or devices. When the control stations report various types, multi-period, and customizable type data, there is a method that can collect, parse, and store data through protocols, realizing the data interaction between other systems or devices and multiple control stations. This solution proposes a method for collecting data from multiple control stations, introduces the NPCAP library for capturing network data packets and data analysis, collects various types, multi-period, and customizable type data of multiple control stations, parses the data through multiple tables, and proposes a data storage scheme to store the data, so that other systems can quickly traverse the data folder to parse the data, improving the data processing efficiency.

[0098] Advantages of the embodiments of the present application: Obtain various types, multiple cycles, and customizable type control station data of multiple control stations of the nuclear power I&C system transmitted based on the Ethernet physical layer and data link layer. Since the customizable type refers to one-dimensional arrays or multi-dimensional arrays of the same type, or one-dimensional arrays or multi-dimensional arrays of different types, this solution supports the parsing of data of customizable types, and realizes the storage of the obtained control station data of multiple control stations by category and by cycle, so as to meet the requirements of other offline data analysis software for the quick traversal and fast reading analysis of control station data, and improve the processing efficiency of the control station data of the nuclear power I&C system.
