[0037] Figure 2 This is a schematic diagram of the structure of the sodium-cooled fast reactor DCS risk analysis and safety intelligent analysis system provided in this application. DETAILED DESCRIPTION

[0038] The following is further explained in detail through specific implementation methods.

[0039] like Figure 1 As shown, the present application provides a sodium-cooled fast reactor DCS risk analysis and safety intelligent analysis method, including:

[0040] Step 1: Data conversion: Based on the provided drawings, tables and other materials, analyze and display the signal connection relationship between the controllers, as well as the I / O signals, forced signals and other functions in each cabinet.

[0041] Automatically parse drawings, tables and other materials, and convert them into data structures that can be recognized by the system, so as to fully display the signal connection relationship between controllers, I / O signals, forced signals and other functions.

[0042] Step 2: Structure display. In the controller interactive signal interface, the controller star map can display the signal connection between the controllers. For a single controller, it is required to display the I / O signal and mandatory signal statistics in order according to the device level for easy viewing.

[0043] Through the controller star diagram, tree branch directory and other methods, the signal connection relationship between controllers and the statistical information of I / O signals and forced signals inside a single controller are intuitively displayed. This display method is not only convenient for viewing, but also can help maintenance personnel better understand the system structure.

[0044] Step 3: Confirm the analysis object. The confirmation method includes selecting the object on the map, intelligently associating the first few digits of the device code entered by the user in the search box, and providing recommended analysis objects through the drop-down method.

[0045] The system provides a variety of ways to confirm the analysis object, including selecting the object on the map, intelligently associating the first few digits of the device code entered by the user in the search box and providing recommended analysis objects through a drop-down method, etc., so that maintenance personnel can quickly locate the equipment or components that need to be analyzed.

[0046] Step 4: Signal isolation analysis: Based on the analysis controller, the controllers connected to it and the corresponding signals are analyzed, which helps maintenance personnel to quickly identify potential risk points and take corresponding countermeasures.

[0047] Step 5: Analyze the controller failure and offline download measures of the controller configuration, including:

[0048] Provide risk response measures in the form of documents or tables;

[0049] According to the affected devices, the logical associated devices, logical alarms and other information of the controllers that need to be installed offline can be listed, and safety measures for controller offline installation, controller failure and cabinet power failure can be automatically generated to provide auxiliary information for maintenance personnel's operations and decisions.

[0050] In one embodiment, the system can provide risk response measures in a document or table format according to the situation of the affected equipment.

[0059] Record the list of points that are in forced status but not restored at the current query time, including the forced point signal name, forced time, forced reason and temporary forced order number.

[0060] In one embodiment, the state parameters of the selected module are first collected in real time through the interface with the industrial automation system, including the module's voltage, current, temperature, operating status, communication status, etc. The collected state parameters are analyzed to determine whether the module is in a normal state. If the system detects any abnormal state parameters, an alarm will be triggered immediately to notify maintenance personnel to handle it in time.

[0061] In one embodiment, based on the status parameters and maintenance data of the module, the system will automatically generate maintenance suggestions, such as regular maintenance, component replacement, etc. The maintenance suggestions are displayed to maintenance personnel so that they can quickly understand and take corresponding maintenance measures.

[0062] In one embodiment, the configuration and data of the industrial automation system are analyzed to identify the points that are currently in a forced state. For each forced point, its signal name, forced time, forced reason, etc. are recorded. This information is summarized to generate a forced point list for maintenance personnel to review.

[0063] In one embodiment, in the mandatory point list, each temporary mandatory order number will be designed as a clickable link. After clicking the link, the system will open the corresponding "DCS signal temporary mandatory tracking sheet during operation".

[0064] Step 7: I / O card fault safety analysis. Analyze the logically associated devices, logical alarms and other information of the signal points in the selected I / O card, and automatically generate safety measures for I / O card restart, card failure replacement, etc., to provide auxiliary information for maintenance personnel's operations and decisions.

For easy viewing, the tree directory is displayed vertically and in layers according to the device type.

[0073] 3) Thumbnail map

[0074] Considering that the directory is deep and the graphics are large, a small map is set at the top of the interface for quick viewing.
