BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 This is a schematic diagram of special tools for auxiliary maintenance. DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 The tool, shown here, is a specialized tool for assisting maintenance of the KIC platform in nuclear power plants. Installed on a DGS or SAS workstation, it features a user-friendly human-machine interface. Each unit in the tool is managed and controlled by account, based on its importance and impact on the site. These include a log classification and statistics unit, an operation trend display unit, a one-click configuration file backup and restore unit, and a screen image capture unit. The log classification and statistics unit, the one-click configuration file backup and restore unit, and the screen image capture unit involve command input and detailed human operation, and require higher-level operator privileges. The operation trend display unit, when used, only involves viewing steps and requires lower-level visitor privileges.

[0028] The log classification and statistics unit includes a log collection module, a log database establishment module, and a data rule list establishment module. The log collection module names the workstation and server according to their names and collection time, and uniformly collects and packages the logs. The log database establishment module extracts log severity information, creates a log severity field, and classifies the logs into ERROR, WARN, and INFO according to severity. The data rule list establishment module establishes a peer relationship between different types of data and different colors according to the type of log data, and displays different types of data in different colors.

[0029] The operational trend display unit includes a module for collecting CPU and memory usage information, a module for establishing an information database, and a module for converting data into images. These modules generate relevant statistical graphs and trends to facilitate analysis of workstation and server operational trends. The module collects server and workstation CPU usage information and memory information, integrating this information to achieve real-time CPU and memory usage data collection. By specifying an update cycle and setting a statistical frequency, the regularly collected CPU usage information can be saved to a 1.txt file. The collected server and workstation CPU usage information includes the percentage of CPU occupied by user space, the percentage of CPU occupied by kernel space, the percentage of CPU occupied by processes with changed priority, and the percentage of idle CPU. The collected server and workstation memory information includes the total physical memory size, used physical memory, and available physical memory. The module for establishing an information database stores CPU and memory usage information by type, allowing data extraction based on type, such as extracting data on the percentage of CPU occupied by user space. The module for converting data into images chronologically converts the extracted data into images, forming operational trends for the server and workstation CPU and memory information.

[0030] The one-click configuration file backup and restoration unit includes a configuration file collection and saving module and a backup file restoration module. The configuration file collection and saving module collects the PI configuration file, GTW configuration file, and Hivision license file and saves the backed-up files in the / home / adacs / bak path. The backup file restoration module restores the files backed up in the configuration file collection and saving module. When restoring the PI configuration file, copy the files in the / home / adacs / sar7str7gtw1(sar8str8gtw2) / NARI_L3_APP / ClientConfig path to the / home / adacs / NARI_L3_APP path. When restoring the GTW configuration file, copy the files in the / home / adacs / bak / sar7str7gtw1(sar8str8gtw2) path to the / home / adacs / ADACS_RT / gtw_files / current_conf path. When restoring the Hivision license file, the files in the / home / adacs / hivision / sas1(sas2) / *.license path will be automatically copied to the sas1:(sas2:) / opt / ihivisionxxxxx / config / licenses path.

[0031] The screen image capture unit includes a screen capture command unit and a unit for categorizing and storing the captured screen images. The integrated screen capture command unit integrates the screen capture command "gnome-panel-screenshot –display=kic-owp11:0.n." The categorized storage unit stores the captured screen images on the workstation according to the categories of "on-site system screen," "periodic test screen," and "accident procedure screen." This facilitates exporting the latest on-site screen images after unit overhaul data is updated, facilitating unit documentation upgrades.

[0032] DCS: Distributed Control System. This computer control system provides centralized operational management and decentralized control of the production process. Microprocessor-based process control stations, distributed throughout the production process, independently control each process flow. These stations are connected to the monitoring and operating stations in the central control room via a data communication system, forming a distributed control system.

[0033] KIC: Power plant computer information and control system. This system belongs to the DCS layer 2 monitoring and control layer, providing computerized monitoring and control functions, including data processing and archiving, software configuration, and interfaces with DCS layers 1 and 3.

[0034] DGS: Data Generation System or ADACS_N (Advanced Data Processing and Control System for Nuclear Applications) Engineering Station.
