Description

Hull block assembly simulation system and method {SYSTEM AND METHOD FOR BLOCK ASSEMBLY SIMULATION IN SHIP PRODUCTION}

The present invention relates to a hull block assembly simulation system and method.

In general, ships are produced through a block assembly method of stacking or connecting unit blocks to each other.

Dimensional accuracy from small blocks, such as unit blocks, to intermediate and large blocks is a very important quality control subject.

The poor dimensional quality of the hull block has been recognized as a major cause of deterioration of the productivity of ship manufacturing by causing many modifications and waiting processes in the block mounting process.

In order to prevent the deterioration of production workability, the dimensional quality management of blocks is briefly summarized by using the precision measuring equipment for large structures to measure or measure the blocks. After comparing or matching the measured values (e.g., block measurement data, measured values, etc.) according to the block measurement, the error value or error in the three-axis direction (e.g., x-axis, y-axis, z-axis) in space If the vehicle is out of the management standard by calculating, calculating, or analyzing the vehicle, the dimensional quality of the hull block is managed by modifying the corresponding area before transferring the block, which is a post-process.

For the dimensional quality management of such hull blocks, the dimensional quality inspection standard document for the hull block (hereinafter referred to as 'the conventional inspection standard document') for each block and the dimensional quality inspection result book for the hull block (hereinafter, 'the conventional inspection result report') Is abbreviated).

Conventional methods of writing these documents include simple document creation using a general document writer, word processor, and other document programs (e.g., MS Word, Hangul, etc.). It is understood as a simple individual document but difficult to use as data.

The hull block includes a block to be mounted in the dock (hereinafter referred to as a 'mounting block') as understood as a PE (Pre-Erection) block, and a block previously mounted in the dock as understood as an ER (Erection) block ( Hereinafter referred to as 'blocks in the dock'.

The conventional inspection standard document and the conventional inspection result document mentioned above are prepared as the mounting block and the simple document for each block in the dock, and then the minimum amount of correction is made by using the documents before the actual block joint using the documents. The block setting method is found through the manual operation described in the background below.

Throughout this specification, the 'correction amount' is calculated by summing error amounts such as gaps, mis-aligns, and steps between the mounting block and the block in the dock for block mounting, and the optimal mounting block setting For cutting, it means the number of cutting or fostering block modification work.

In the prior art, as shown in Fig. 1, the measurement block object selection step (S10), the conventional inspection criteria document creation step (S20, S21) for the mounting block and the in-dock block, the mounting block and the in-dock block measurement step (S30, S31), the error amount calculation step (S40, S41), the conventional inspection result writing step (S50, S51), the initial correction amount calculation step (S60), the optimum correction amount calculation step (S70) for the mounting block and the in-dock block are performed do.

Looking at this step by step, in the measurement block object selection step (S10), after the planning of the block division of the designed ship is finished, the department in charge of the dimensional quality of the block performs inspection blocks for each process (eg, mounting blocks, blocks in the dock, etc.). Select and plan the overall schedule.

In the step S20 and S21 of preparing the conventional inspection criteria document for the mounting block and the block in the dock, the block sections to be jointed in the corresponding blocks are extracted from the design system, and the design regular dimensions are used by using the drawing contents corresponding to the extracted block sections. Display (Dimension).

In the block measurement step (S30, S31) in the mounting block and the dock, the block sections to be jointed are measured by using a measurement system such as 3D measurement equipment for large structures or IGPS (Indoor Global Positioning System) using optical technology and conventional inspection. On the reference document, the measuring position (eg measuring point position) and the sequence are recorded.

In the error calculation step (S40, S41), when the actual measurement is finished through the above-mentioned measurement operation, the design value for the measured value at each measurement position to quantitatively determine the dimensional quality of the mounting block and the block in the dock The operation of calculating the contrast error amount is performed. At this time, coordinate conversion is performed so that the measured value is placed on the same axis as the design value by using a separate coordinate conversion program.When calculating the amount of error, it is necessary to obtain all the design values for each measuring point corresponding to hundreds of measurement points. Therefore, the design value of the axis of interest of the corresponding section is obtained and only the error amount of one axis is calculated separately using a commercial program equipped with a spreadsheet function. Therefore, it may take a lot of time when the coordinate transformation and human error may occur.

In the step (S50, S51) of preparing the conventional inspection result for the mounting block and the block in the dock, the conventional inspection result report (e.g., check sheet) that checks the dimensional quality of the block is completed, and the calculated error amount and the conventional inspection standard document are On the basis of this, the error amount at each measurement position is written together on the drawing. This is done by handwriting. In many cases, the error amount is recorded directly for each of the hundreds of measurement points, which can take a lot of time and cause no data accumulation.

In the initial correction amount calculating step (S60), the initial correction amount is calculated by summing the mounting block error amount and the error amount of the block in the dock corresponding thereto. This is also done by manual calculation and takes a lot of time.

In the calculation of the optimum correction amount (S70), while performing the repetitive operation based on the initial correction amount, the correction amount is calculated by recalculating the error amount compared to the design value of the measured value each time. This work yields the optimal amount of correction. This work is also done by manual calculation and shows a lot of difference in time and accuracy according to the user's skill.

Then, the correction amount is manually recorded by the hundreds of measurement positions in the conventional inspection standard document for the mounting block. This can be said to be the most time-consuming task compared to the previous tasks.

As described above, in the preparation of the conventional inspection standard document or the conventional inspection result document, it is created by hand firstly and secondly, by manually writing the result of the handwriting into a word processor program, repetitive tasks are generated, requiring a lot of work time, and easy. It is difficult to create a simple, and in particular, due to the absence of a means for easily and conveniently simulating the task of calculating the correction amount between the mounting block and the block in the dock, excessive work time is required along with the inconvenience of excessive manual work. In addition, quality deviation occurs between skilled and unskilled workers, and it is necessary to check, judge, and work in parallel with manual work.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, the measurement of the mounting block (eg PE block) and the in-dock block (eg ER block) using the simulation smart settings window The hull block can be used to calculate the amount of error compared to the design value of each block using the value, and to easily and quickly generate an integrated simulation result file including the calculation of the correction amount before the mounting operation of the mounting block using the calculated error amount.

The aim is to provide a hull block assembly simulation method that allows for the quick, easy and systematic setup and management of the optimal mounting block settings within the limits of the dimensional quality.

The main terms to be mentioned in the present embodiment 100 are defined.

The hull block assembly simulation algorithm is defined to execute the stepwise hull block assembly simulation method described below through the computer device 110 to derive the desired output from a given input.

The integrated inspection standard document is produced by the system and method for preparing the dimensional quality inspection standard document for the hull block of Korean Patent Application No. 10-2007-0072834 as filed by the applicant.

The integrated inspection criteria document is based on a computer data system and has a workbook format that supports spreadsheets or Excel data, objects, and tags, as well as data such as strings in simple computerized documents. All design values for each measurement location or candidate location for measurement are databaseed and stored in the document, which means that they can be used as information sharing, statistical analysis, and monitoring means.

The integrated inspection criteria document copies the block shape with the block cross section to be jointed for each of the mounting block or the block in the dock, and inputs it in the form of an image file in the form of a figure, and minimizes the top, bottom, left and right end points of each block cross section.

Based on the design values, the range of cuboids containing the corresponding cross sections is set individually and included in that range of all measurement data. The measurement data included are selected and the amount of error is automatically calculated relative to the design value in the direction of the axis of interest for each section, and the color ball containing the error values calculated by finding the position on the corresponding section corresponding to the position of the measurement point of each section (E.g., error balloons) and show the block shape or cross-sectional shape with basic measurement information and colored balls.

In particular, the processing results for various functions associated with the simulation smart setting window 202 are shown.

The simulation smart setting window 202 corresponds to a low-acting tool for importing the first integrated inspection result for the mounted block and the second integrated inspection result for the block in the dock and consequently creating an integrated simulation result file.

4 to examine the hull block assembly simulation method.

Referring to Figure 4, the hull block assembly simulation method is a simulation smart setting window execution step (S100), the first integrated inspection result open step (S200), the second integrated inspection result open step (S300), the index between the integrated inspection results Matching step (S400), the initial correction amount calculation step (S500), the optimum correction amount calculation step (S600), the simulation result file web registration step (S700).

Before the execution of the simulation smart setting window (S100), after the mounting block to be simulated and the block in the dock are selected, the first integrated inspection result for the mounting block and the second block for the block are selected by the dimensional quality inspection result preparation system for the hull block. An integrated inspection result sheet is prepared, the first integrated inspection result sheet and the second integrated inspection result sheet are downloaded to the computer device of the present invention through the operating system, and the hull block assembly simulation algorithm of the computer device is executed.

In the execution of the simulation smart setting window (S100), a menu or a toolbar provided by the hull block assembly simulation algorithm is used by the user, so that the simulation smart setting window is overlapped on the top layer of the editing screen of the work window.

The first integrated inspection result opening step (S200) is a file explorer linked to the second button of the activated simulation smart setting window, accessing the first integrated inspection result and opening the first integrated inspection result program to the hull block assembly simulation algorithm. It is the process of connecting them.

The second integrated inspection result opening step (S300) is a file explorer linked to the third button of the activated simulation smart setting window, and accesses the second integrated inspection result and opens the second integrated inspection result program to the hull block assembly simulation algorithm. It is the process of connecting them.

Through the opening steps (S200, S300), the first and second integrated inspection results are overlapped on the editing screen of the work window, and the first and second integrated inspections are performed using the screen display function to be described with reference to FIG. The block cross-sectional shape and the amount of error are displayed in the form in which one of the results is written.

The index matching step (S400) between the integrated check result documents may include a first index matching principle using a preset tolerance when the reference origins of the two blocks are the same, or an automatic matching when the reference origins of the two blocks are different. It is a process of matching index information, that is, matching points, through a two-index matching principle.

The first index matching principle is performed when the reference origins of two blocks are the same based on the first and second integrated test results, and the preset tolerance between the measured value groups on the two block cross sections through a computer internal calculation is performed. It means to search and match measured values satisfying (Tolerance).

The second index matching principle is performed when the reference origins of the two blocks are different based on the first and second integrated test results, and as described in detail with reference to FIG. 6, the first integrated test programmatically interconnected. By means of extracting a set of design values for each block cross section to be jointed between the result book and the second integrated test result book, and automatically matching them, it means securing matching index information.

The initial correction amount calculating step (S500) corresponds to a step of calculating an amount of error compared to the design value of each block by using the measured values of the two matched blocks, and adding or subtracting the calculated error amounts to calculate the amount of correction. .

Optimum correction amount calculating step (S600) is a process of performing a block fine adjustment using the simulation smart setting window based on the initial correction amount calculation result. That is, the optimal correction amount calculating step (S600) is synchronized with the coordinate transformation function, and recalculates the error amount and correction amount each time there is a coordinate transformation and displays them through a table in the simulation smart setting window, thereby allowing the dimensional quality of the corresponding block. Corresponding to the step of calculating the optimal mounted block correction amount within the limit.

This optimal correction amount calculation step (S600) is linked or synchronized with the coordinate transformation function.

That is, the hull block assembly simulation algorithm is programmed to recalculate the error amount and correction amount with the converted value every time the coordinate transformation function is used by the user, so that the user can easily block, error amount and number. It allows to change the quantity and its display state, making it easy to find the optimum mounting block setting corresponding to the minimum amount of error, and to save it as the setting result.

In addition, the hull block assembly simulation algorithm provides the integrated simulation result file opening function linked to the first button so that the integrated simulation result file can be stored in a computer device or the like, or other stored simulation result files can be loaded and viewed.

In addition, the hull block assembly simulation algorithm performs a correction amount display process of displaying the correction amount calculated through the optimal correction amount calculating step (S600) using numerals and arrow marks in the first and second integrated inspection results.

The simulation result file web registration step (S700) is a step of uploading and registering the completed and stored integrated simulation result file on the website of the operating system or the centralized web system.

Registered integrated simulation result files can be viewed and downloaded to various workers or users for convenient information sharing.

This integrated simulation result file can reduce the time required to identify block dimensional quality relatively, share feedback necessary for preprocess or post process, and use it for statistical analysis of dimensional quality problem. DB accumulation allows monitoring of the overall block quality.

Hereinafter, the details of the hull block assembly simulation system of the present invention will be described based on the simulation smart setting window.

Referring to FIG. 5, the first button 210 provided in the simulation smart setting window 202 is for opening a previously created integrated simulation result file, and means for opening a previously created integrated simulation result file for modification, editing, and resave. Is understood.

That is, when the first button 210 is clicked with a mouse, an open menu similar to a file explorer is executed in a pop-up format.

When finding and opening the integrated simulation result file previously worked in the open menu or opening the training sample file, the contents of the integrated simulation result file are displayed on the edit screen 201a of the work window 201 shown in FIG. It can be displayed, modified, edited and restored.

In addition, when the second button 211 for opening the first integrated inspection result book of the simulation smart setting window 202 is clicked with a mouse, an open menu similar to the file explorer is executed in a pop-up form. When the first integrated inspection result sheet prepared in advance is found and opened in the open menu, the contents of the first integrated inspection result are displayed on the editing screen of the work window 201, and are connected programmatically to the hull block assembly simulation algorithm. .

To prepare an index match with the first integrated test result book.

The fourth button 213 for hiding a table display performs one of a table display (eg, bottom of FIG. 5) and a table hide (eg, top of FIG. 5) corresponding to a mouse click.

For example, corresponding to the mouse click of the fourth button 213, the simulation smart setting window 202 is enlarged or restored to its original size, so that the tables t1 and t2 are eventually shown or hidden.

The expanded area in the simulation smart setting window 202 may be adjusted by the mouse drag function m.

One side (e.g., right) of the tables t1 and t2 (t1) is a relative index of the amount of error compared to the design value of the measured value of the first integrated inspection result, the correction amount for each of three axes, and the number matching between the two blocks. Including information (e.g. matching points).

The other side (e.g., left) table t2 of the tables t1 and t2 is displayed including the amount of error compared to the design value of the measured value contained in the second integrated inspection result and the relative index information for the number matching between the two blocks. do.

In addition, the fifth button 214 for storing the setting result of the simulation smart setting window 202 realizes a function of temporarily storing the converted information for each conversion result through coordinate transformation when the user proceeds. This can be done through a separate setting result view window (not shown) with functions such as saving settings, executing settings, deleting, and closing.

In addition, the simulation smart setting window 202 has a tab for index matching, and when the location is activated, an index matching button 220 is provided. When the index matching button 220 is clicked, the following index matching is performed. Proceed.

As shown in FIG. 6, conceptualized description will be provided to facilitate understanding of index matching.

The first integrated test result may have a block shape b1 on the left side and a design value distribution (original characters 1 to 101) of the block shape b1, and has a first block cross section bs1 to be joined at this time. .

The second integrated inspection result may have a block shape b2 on the right side and a design value distribution (original letters 1 to 100) of the block shape b2, and has a second block cross section bs2 to be joined.

The index matching allows the computer device to match the measurement values to be calculated after the user designates the first block section bs1 and the second block section bs2 to be jointed with each other and recognizes the computer device. Means to secure index information.

The detailed process of index matching is as follows.

The user can use the mouse to select any three points (eg left original 2, 4, 8 and right original 1, 5, By specifying (eg, clicking) 7), the first and second block sections bs1 and bs2 to be matched or jointed are defined. Through this, the computer apparatus may recognize the first and second block sections bs1 and bs2 to be jointed between the first integrated test report and the second integrated test report.

The computer apparatus uses three points each specified in each of the first and second block sections bs1 and bs2 to be jointed, and calculates a normal vector of the plane through the cross product of the vector, and then one point among the three points. The equations of the plane are constructed by using and the normal vector, respectively.

The computer device then retrieves a design value with a distance of 0 between each between the first block cross section bs1 defined by the equation of the plane and all points of the design value distribution of the block shape b1, and eventually The group of design values corresponding to the original characters 1 to 8 of the first block section bs1 is detected.

In the same way, the computer device retrieves the design values with the number 0 between each between the second block cross section bs2 defined by the equation of the other plane and all points of the design value distribution of the block shape b2. Finally, the group of design values corresponding to the original characters 1 to 7 of the second block section bs2 is detected.

The computer device extracts the detected design value group for each of the first and second integrated inspection result books.

The computer device automatically matches the extracted set of design values.

The automatic matching of the computer device calculates the optimal coordinate transformation matrix based on the calculation of the computer device without providing any matching information, and designates the design value corresponding to the second integrated test result sheet to the design value of the first integrated test result sheet. As a method of automatically matching and converting a design value group of the second integrated inspection result book, it is programmed by applying an iterative closest point (ICP) algorithm.

The computer device obtains index information matching between the first integrated test result book and the second integrated test result book through the automatic matching.

Referring to FIG. 5, the simulation smart setting window 202 is provided with various coordinate transformation tabs 230 for executing a coordinate transformation function.

As can be intuitively understood through the name of the coordinate conversion tab 230, the plurality of coordinate conversion tab 230 is used to convert and adjust the measured value group of the first integrated test result and the second integrated test result.

Here, the coordinate transformation tab 230 provides various transformation methods by those skilled in the art using general computer coordinate transformation techniques such as translation and rotation.

Each time the above-described coordinate conversion function is performed, the error amount and the correction amount for each of the three axes are recalculated and updated in real time in the tables t1 and t2 shown in FIG. 5. For example, the one-side table t1 corresponding to the right side synchronizes the error amount or the three-axis correction amount [X (c / t), Y (c / t), Z (c / t)] with the coordinate transformation function. Redisplay.

In addition, the error amount or the correction amount for each of the three axes is also reflected in the error balloon hole 260 as shown in FIG.

5 or 7, the simulation smart setting window 202 provides a screen display function through the screen display area 240.

The screen display area 240 includes a first confirmation box labeled 'LEA1 / PE' and a second confirmation box labeled 'correction amount'.

The first confirmation box marked 'LEA1 / PE' shows the first integrated inspection result on the editing screen of the task pane according to its checkmark display, or the second integrated inspection result report on the editing window of the task pane according to its checkmark removal. It is in charge of the function shown in the award.

The second confirmation box marked 'correction' displays or updates the correction amount, which is the sum of the error amounts of the two block cross-sections, according to the display of his check mark, and the value corresponding to the position to be corrected. Also reflected and displayed in real time to the corresponding error balloon 260 of Figure 7, or in accordance with the removal of the check mark is responsible for the function of displaying the error amount, such as the format or content of the existing integrated inspection results instead of the correction amount.

Through this, the user can numerically view the correction amount of the block cross-section to be jointed and move the block shape using the tab 230 for coordinate transformation of the simulation smart setting window 202, and the correction amount is automatically reset every time. Since it is calculated and displayed, it is possible to understand the assembly state between two blocks, and fine tuning can easily perform the optimal block setting.

7 or 8, the simulation smart setting window 202 provides an error amount display function through the error amount display area 250.

In the error amount display area 250, an open list menu labeled 'Tol' is used to determine a tolerance to be used for the aforementioned first index matching principle.

For example, when the tolerance of the open list menu is set to 100, each measured value in the measured value group is recognized as a matching point in the system when the distance between the corresponding design values is within 100 mm.

In the error amount display area 250, a one-line text box marked 'error' is used to define a setting error for determining whether to correct. For example, when the numerical value of the setting error described in the one-line text box is 10, as shown in FIG. 8, the error balloon hole 261 at the measurement position where the setting error occurs in the three-axis direction by 10 mm or more is displayed in red. It is intended to convey graphical information to the user.

In the error amount display area 250, the confirmation box described as 'index display' shows a function of turning on or off the index display of the measured value.

In the error amount display area 240, the confirmation box indicated by the 'error arrow' enables to selectively display the text display of the error value (left figure in FIG. 8) or the error arrow display for each of three axes (right figure in FIG. 8). Do it.
