[0085] The following is further explained in detail through specific implementation methods.

[0086] like Figure 1 and Figure 2 As shown, the present invention provides a nuclear power DCS control system log parsing method, comprising the following steps:

[0087] Step 1: Collect DCS logs. Configure the log collection task, set the log collection method, log tag, log directory, and collection task scheduling.

[0088] Log collection methods include online collection and offline collection, and usually only one of them is used. Online collection automatically collects log files by parsing the log push protocol (including at least the SCP protocol), while offline collection manually collects log files by uploading local files.

[0089] Log tags provide supplementary information for asset management by users selecting tag information such as power plants, units, equipment models, and log types.

[0090] Better manage the collected log files by selecting the log directory.

[0091] Task scheduling configuration controls log collection tasks by setting log collection time, collection frequency, etc.

[0092] Step 1 specifically includes:

[0093] Step 1.1: Offline collection. Set the metadata information of the log file, including the power plant, unit, and file storage directory, select the files to be uploaded, and confirm the ownership of the log data based on the metadata information. The log file management path is determined by the storage directory.

[0094] Offline collection includes: creating a new collection task, selecting a file storage directory, selecting a power plant unit, selecting a file, and uploading a log file. Specifically, it includes:

[0095] 1) Perform offline collection through the log collection module and add offline collection tasks;

[0096] 2) Configure basic task information: task name, file storage directory, and power plant unit to which it belongs;

[0097] 3) Select the file to be uploaded and submit the task. The collection task will automatically run to upload the log file.

[0098] Step 1.2: Online collection. Set the metadata information of the log file, including the power plant, unit, and file storage directory; set the source information of the log file, including the source file server address, connection method, and authentication information; set the collection task scheduling information, that is, the automatic acquisition frequency information of the log file, including the scheduling time and scheduling cycle. Based on the metadata information, confirm the ownership of the log data, and determine the log file management path by the storage directory; confirm the automatic acquisition frequency of the log file by the collection task scheduling information, and incrementally obtain the log files within the frequency period to realize the automatic collection of log files.

[0099] Online collection includes: creating a new collection task, configuring data source, selecting file storage directory, configuring task running time, configuring task running frequency, and uploading log files. Specifically include:

[0100] 1) Configure data source information: source file server address, access account information, and collection protocol;

[0101] 2) Collect data online through the log collection module and add online tasks;

[0102] 3) Configure basic task information: task name, file storage directory, and power plant unit to which it belongs;

[0103] 4) Select the data source to be collected and configure the scheduling information of the collection task: task running time and task running frequency;

[0104] 5) Submit the configured task scheduling information and basic task information, and run, collect, and store log files autonomously.

[0105] Among them, log storage involves step 1, log parsing result storage involves step 3, and metadata storage involves every step.

[0106] For log storage, the collected log files are stored and archived according to a certain period.

[0107] For log analysis result storage, the DCS data after log analysis is stored in a time series database in a unified format.

[0108] For metadata storage, label information as well as business metadata, operation metadata and technical metadata generated by the system itself are stored.

[0121] After selecting multiple or a single file, set the corresponding type of parsing rules to perform a single file parsing on the selected file. Specifically, select multiple files, select parsing rules, and parse all files in the directory; select a single file, select parsing rules, parse the selected file, and view the parsing results.

[0122] Select the file storage directory, set the parsing rules and scheduling information, identify the unparsed files in the selected directory according to the set scheduling time and cycle, and perform file parsing according to the selected parsing rules to achieve automatic parsing of log files. Specifically, select the file directory, select the parsing rules, select the scheduling cycle, select the effective time, and parse all files in the directory.

[0123] Step 4: Parsing rule management. The system presets some parsing rules and supports user-defined parsing rules to achieve the scalability of parsing rules.

[0124] Parsing rule management includes:

[0125] 1) Parsing rule display: Displays the basic information of all parsing rules integrated in the system: rule name, usage log type, creation time, and task description;

[0126] 2) Add new parsing rules: Add new rules script editing, support scripts and programs in multiple programming languages ​​such as Python, Java, regular expressions, etc., and you can also directly upload the completed script files;
