Description

Technical Field

[0001] This application belongs to the field of support timber repair technology, specifically, it relates to a system and method for generating a repair scheme for cracks in marine support timber. Background Technology

[0002] Marine support timber is a key load-bearing component in the support system of ship decks, cabin equipment, and hull structure. It is mostly made of hardwood and is subject to complex conditions such as long-term marine salt spray corrosion, low temperature and humidity, and alternating load impact. It is very prone to damage such as surface cracks and deep through cracks. Cracks in support timber directly reduce its shear area and load-bearing capacity. If repair is not standardized or timely, it will significantly reduce the safety factor of the ship structure and even affect the safety of ship navigation and operation. It is a core control link in the daily inspection, maintenance and upkeep of ships.

[0003] Currently, the repair of cracks in marine support timber mainly relies on on-site manual inspection and experience-based judgment by marine maintenance personnel. The industry lacks a damage assessment system adapted to legal ship regulations and based on quantitative data, and there is no standardized and intelligent repair solution generation mechanism. The entire repair process depends on manual control, which is difficult to meet the refined and standardized maintenance requirements for safe ship operation. Damage assessment relies entirely on manual visual inspection, and the assessment results have a large subjective bias and cannot accurately match the safe load threshold required by ship regulations, which is prone to misjudgment of damage. Moreover, the classification of repair levels corresponding to different degrees of damage is vague, which easily leads to under-repair or over-repair. There are no unified standards for repair process parameters and operation steps, and the repair quality depends entirely on the experience of the construction personnel, making it difficult to guarantee the performance after repair. Summary of the Invention

[0004] To address the aforementioned problems and technical deficiencies, this application adopts the following technical solution: a system and method for generating a repair scheme for cracked marine support timber, comprising the following steps: The system obtains the load calculation results of the supporting timber input by the user through the interactive interface, and calculates other relevant parameters according to the preset correlation calculation logic. A pre-defined grading assessment matrix is ​​used to evaluate the repair level of crack damage based on a grading assessment algorithm that considers strength loss rate and safety factor, and to generate corresponding assessment descriptions. Based on the assessed repair level, the corresponding standardized repair method and its associated detailed steps and process element set are matched and retrieved from the pre-set repair method database. A vector graphic library is established. Based on the standardized repair method of matching, the corresponding elements are called from the vector graphic library. The spatial layout and rendering are performed according to the predefined process logic to generate a two-dimensional or three-dimensional repair schematic diagram corresponding to the selected repair scheme. The load calculation results, repair level, assessment conclusions, repair plan steps, and repair diagrams are integrated into a structured repair plan report.

[0005] Preferably, the load calculation result data includes: Original shear area, crack projected area, effective shear area, area loss rate, original bearing capacity, residual bearing capacity, strength loss rate, and safety factor; The formula for calculating the strength loss rate is as follows: ; in, For strength loss rate, For effective shear area, This represents the original shear area. For the remaining bearing capacity, Original bearing capacity; The formula for calculating the safety factor is as follows: ; in, For safety reasons, For the remaining bearing capacity, This is the preset minimum safe load threshold required by ship specifications for this support timber.

[0006] Furthermore, the grading assessment matrix is ​​a multi-dimensional decision table, and its parameters can be dynamically configured according to ship type, timber type, and usage location, through strength loss rate. Each threshold Each interval is associated with an independent and distinct safety factor threshold. This involves mapping different strength loss rate ranges and safety factor thresholds to different repair levels, specifically including: like and If so, it is rated as Class A repair level, indicating minor surface damage; like and If so, it is rated as a Class B repair level, indicating moderate crack damage; like and If the damage is severe, it will be assessed as a Class C repair level, indicating severe crack damage that requires crack stabilization. like and If the damage is classified as Class D repair level, it indicates ultimate crack damage and requires structural reinforcement. Otherwise, it will be rated as a Class E repair level, meaning it is irreparable and requires complete replacement.

[0007] Furthermore, the repair method database is indexed by repair level and pre-stores at least four standardized repair methods. Each standardized repair method includes detailed, step-by-step operation instructions, including: Class A repair methods are surface protection methods, which correspond to surface coating protection processes. The steps include cleaning, applying low-temperature epoxy resin, curing, and forming a protective layer. Type B repair methods are pressure injection methods, which correspond to multi-pressure injection processes, including deep cleaning, surface sealing, pressure injection, and curing. Type C repair method is crack-stopping injection method, which corresponds to the pressure injection process after drilling crack stop, and the steps include drilling crack stop, pressure injection through crack, and curing. Type D repair method is the inlay strip repair method, which corresponds to the grooved inlay strip bonding process. The steps include grooving, making and pressing in matching inlay strips, and applying adhesive for bonding.

[0008] Furthermore, each of the standardized repair methods is also associated with an XML or JSON structured data file containing a set of process elements, specifically including: The set of process elements associated with Class A repair methods is: {Process Name: Surface Protection, Operation: [Cleaning, Applying Low-Temperature Epoxy Resin, Curing], Graphic Elements: [Coating Coverage Area]}; The set of process elements associated with the Class B repair method is: {Process Name: Pressure Injection, Operation: [Deep Cleaning, Surface Sealing, Pressure Injection, Curing], Graphic Elements: [Injection Area, Multiple Injection Points, Flow Arrow]}; The set of process elements associated with the C-type repair method is: {Process name: crack arrest injection, Operation: [Drilling to arrest cracks, pressure injection through cracks, curing], Graphic elements: [Crack, location of crack arrest drilling, injection path, flow direction]}; The set of process elements associated with the D-type repair method is: {Process name: inlay repair, Operation: [grooving, making and pressing in matching inlays, applying adhesive], Graphic elements: [grooving area, inlay entity, adhesive layer diagram]}.

[0009] Preferably, the repair diagram is a visual diagram that includes cracks and key elements of the repair operation, dynamically displaying the key elements of the repair process corresponding to the repair plan, showing one or more of the following: the wood body, the location of the crack, the area covered by the repair material, the glue injection point, the drilling location, and the location of the inlay strip, and accompanied by illustrations. The repair diagram can dynamically render different elements based on different repair methods, including: For the Class A repair method, a surface coating layer is generated that extends outward by a preset distance based on the crack boundary. For the B-type repair method, based on the crack morphology, multiple injection points are generated along the crack path, and multiple flow arrows pointing to the core area of ​​the crack are generated from each injection point. For Class C repair methods, the rendering includes a first graphic element representing the wood itself, a second graphic element representing the crack, a third graphic element representing the location of at least two anti-crack drill holes, and a fourth graphic element representing the direction of glue flow from one end of the drill hole to the other end. For the D-type repair method, a rectangular slotted area is calculated and rendered based on the crack length, and a strip model matching the size of the slot is rendered within this area, along with a schematic of the adhesive layer between the strip and the slot wall.

[0010] Furthermore, when the repair level is Class C, the following mandatory rendering logic is executed: Call the first graphic element and render it as a semi-transparent 3D block model; Call the second graphical element, based on the input crack projected area. The data is used to render a crack on the surface of the wood model whose width and length match the geometric features of the crack's projected area. The crack length is calculated based on the crack projection area and the preset crack width model. At least two third graphic elements are calculated and rendered. Their distribution logic is as follows: a drill hole is set at each end of the crack. If the crack length exceeds the preset length threshold, drill holes are added at equal intervals in the middle of the crack to form a drill hole sequence. Render the fourth graphic element, which is a line with directional arrows. Its path is forcibly set to start from the crack arresting hole position at one end, connect all the crack arresting hole positions in sequence along the crack direction, and finally reach the crack arresting hole position at the other end.

The grade assessment module has a preset grade assessment matrix. Based on the grade assessment algorithm of strength loss rate and safety factor, it evaluates the repair grade of crack damage and generates the corresponding assessment description. The method generation module matches and retrieves the corresponding standardized repair method and its associated detailed steps and process element set from the pre-set repair method database based on the assessed repair level. The repair schematic module establishes a vector library, calls corresponding elements from the vector library based on a standardized repair method of matching, performs spatial layout and rendering according to predefined process logic, and generates a two-dimensional or three-dimensional repair schematic diagram corresponding to the selected repair scheme. The report generation module integrates load calculation results, repair level, assessment conclusions, repair plan steps, and repair diagrams into a structured repair plan report.

It dynamically displays the key elements of the repair process corresponding to the repair plan, showing one or more of the following: the wood body, the location of the crack, the area covered by the repair material, the glue injection point, the drilling location, and the location of the inlay strip, and is accompanied by illustrations. The repair diagram can dynamically render different elements based on different repair methods, including: For the Class A repair method, a surface coating layer is generated that extends outward by a preset distance based on the crack boundary. For the B-type repair method, based on the crack morphology, multiple injection points are generated along the crack path, and multiple flow arrows pointing to the core area of ​​the crack are generated from each injection point. For Class C repair methods, the rendering includes a first graphic element representing the wood itself, a second graphic element representing the crack, a third graphic element representing the location of at least two anti-crack drill holes, and a fourth graphic element representing the direction of glue flow from one end of the drill hole to the other end. For the D-type repair method, a rectangular slotted area is calculated and rendered based on the crack length, and a strip model matching the size of the slot is rendered within this area, along with a schematic of the adhesive layer between the strip and the slot wall.

[0024] When the repair level is C, the following mandatory rendering logic is executed: Call the first graphic element and render it as a semi-transparent 3D block model; Call the second graphical element, based on the input crack projected area. The data is used to render a crack on the surface of the wood model whose width and length match the geometric features of the crack's projected area. The crack length is calculated based on the crack projection area and the preset crack width model. At least two third graphic elements are calculated and rendered. Their distribution logic is as follows: a drill hole is set at each end of the crack. If the crack length exceeds the preset length threshold, drill holes are added at equal intervals in the middle of the crack to form a drill hole sequence. Render the fourth graphic element, which is a line with directional arrows. Its path is forcibly set to start from the crack arresting hole position at one end, connect all the crack arresting hole positions in sequence along the crack direction, and finally reach the crack arresting hole position at the other end.

[0025] The load calculation results, repair level, assessment conclusions, repair plan steps, and repair diagrams are integrated into a structured repair plan report.

[0026] Example 2, as Figure 2 As shown, a system for generating a repair solution for cracks in marine support timber includes: The data interaction module obtains the load calculation results of the supporting timber input by the user through the interactive interface, and calculates other related parameters according to the preset correlation calculation logic. The grade assessment module has a preset grade assessment matrix. Based on the grade assessment algorithm of strength loss rate and safety factor, it evaluates the repair grade of crack damage and generates the corresponding assessment description. The method generation module matches and retrieves the corresponding standardized repair method and its associated detailed steps and process element set from the pre-set repair method database based on the assessed repair level. The repair schematic module establishes a vector library, calls corresponding elements from the vector library based on a standardized repair method of matching, performs spatial layout and rendering according to predefined process logic, and generates a two-dimensional or three-dimensional repair schematic diagram corresponding to the selected repair scheme. The report generation module integrates load calculation results, repair level, assessment conclusions, repair plan steps, and repair diagrams into a structured repair plan report.

[0027] Data Input and Calculation Module: Implemented in the form of a web page, it contains 8 data input items (original shear area, crack projection area, etc.). The module uses JavaScript event listeners to realize real-time linkage calculation of input items (such as automatically updating the loss rate when the original area and crack area are modified).

[0028] Intelligent evaluation module: Implemented using front-end JavaScript functions, with the core being the determineAssessmentGrade() function, which has built-in evaluation matrix logic as described above.

[0029] The repair solution generation module includes a predefined repair step knowledge base (stored in object form) and a solution matching and dynamic HTML content generation function displayRepairMethod().

[0030] Visualization module: via HTML5 Elements are dynamically constructed using CSS absolute positioning technology. The core function displayRepairDiagram() draws the wood background and crack lines within a specified container based on the passed-in repair method type (A / B / C / D), and adds colored layers, dots (glue dots / drill holes), arrows (flow direction), and geometric shapes (inserts) representing different repair techniques.

[0031] Solution Export Module: Using JavaScript's Blob object and the URL.createObjectURL() method, the concatenated solution text is generated as a .txt file for users to download.

[0032] The system's operation process includes: Users can input or modify load data in the interface; Click to calculate the assessment, which will trigger the intelligent assessment module. The evaluation module calls the algorithm to output the repair level (e.g., "Class C") and a description.

[0033] Click to generate a repair plan. The system will call the corresponding repair steps according to the level and trigger the visualization module to generate a schematic diagram.

[0034] Users can click "Export Solution" to download all the information in a package.

[0035] The evaluation algorithm implementation details use strength loss rate (X-axis) and safety factor (Y-axis) as two-dimensional judgment criteria. The system reads these two values ​​input by the user and determines the corresponding repair level based on which preset rectangular area they fall into. For example, the input (strength loss 8%, safety factor 1.3) falls into the "Class C" area.

[0036] Visualizing implementation details: Taking the generation of a Class C repair diagram as an example. The `displayRepairDiagram('C')` function performs the following operations: exist Create a brown rectangle inside as the "wood body".

[0037] Create a thin red rectangle and rotate it at a certain angle to represent a "crack".

[0038] Create two blue circles at specific locations at both ends of the crack extension line. Add the "Start Hole" and "Arrest Hole" tags to indicate an arresting hole.

[0039] Create a semi-transparent purple rectangle along the crack direction to represent the "glue filling area".

[0040] Create a blue arrow (made of a rectangle) and a triangle (Composition), pointing from the starting hole to the crack arresting hole, and adding the "Injection Direction" label to indicate the direction of glue flow.

[0041] This dynamically generated diagram intuitively conveys the core process of "drilling to stop cracks and pressure injection to penetrate".

[0042] This system can be deployed through a standard web server, and users can access and use it through a browser without installing a dedicated client, making it easy to apply flexibly in various scenarios such as ship construction sites, offices, and workshops.

If the crack length exceeds the preset length threshold, drill holes are added at equal intervals in the middle of the crack to form a drill hole sequence. Render the fourth graphic element, which is a line with directional arrows. Its path is forcibly set to start from the crack arresting hole position at one end, connect all the crack arresting hole positions in sequence along the crack direction, and finally reach the crack arresting hole position at the other end.

8. A system for generating a repair solution for cracks in marine support timber, characterized in that, include: The data interaction module obtains the load calculation results of the supporting timber input by the user through the interactive interface, and calculates other related parameters according to the preset correlation calculation logic. The grade assessment module has a preset grade assessment matrix. Based on the grade assessment algorithm of strength loss rate and safety factor, it evaluates the repair grade of crack damage and generates the corresponding assessment description. The method generation module matches and retrieves the corresponding standardized repair method and its associated detailed steps and process element set from the pre-set repair method database based on the assessed repair level. The repair schematic module establishes a vector library, calls corresponding elements from the vector library based on a standardized repair method of matching, performs spatial layout and rendering according to predefined process logic, and generates a two-dimensional or three-dimensional repair schematic diagram corresponding to the selected repair scheme. The report generation module integrates load calculation results, repair level, assessment conclusions, repair plan steps, and repair diagrams into a structured repair plan report.
