Description

TECHNICAL FIELD [0001] The present invention relates to a method of automatically arranging an assembly of a fixed table using model information when a ship is built,

The present invention relates to a method for automatically arranging an assembly of fixed platens using model information in shipbuilding, in which assembly projected shape information is extracted from model data on a fixed platen, which is a shipbuilding workplace, and automatically arranged by applying various constraints and algorithms. Especially, considering the characteristics of the assembly workshop, the work priority of the assembly according to the schedule schedule is set in the defined work platform, and then the bitmap image of the assembly having various shapes is extracted to consider the size and the load of the work platform And automatically arranging them.

Generally, in order to dry the ship, it is necessary to start the sales design according to the type of ship (merchant ship, special ship, etc.) and size (displacement amount) When the sales design is started, detailed design is made, and the purchase schedule is established accordingly, and then the middle planning is established so as to link with the above purchase schedule. When the detailed design and middle planning is established, the production design necessary for production is made again, and the small schedule necessary for production is established by departments and processes, as well as the goods are purchased and the production is executed.

In other words, if the ship is ordered, the plan for the quotation-design-production will be concurrently carried out. In the production stage, a mid- to long-term plan (large schedule) will be established and a plan for 6 to 12 months We will set up a plan and schedule a small schedule for each production stage. When the production process is carried out according to the above-mentioned small-scale schedule, each assembly constituting the hull is assembled in the workplace, that is, the fixed base. By assembling, assembling, painting, It will be done.

That is, the assembly is carried out in the order of, for example, sub-assembly (subassembly), bass assembly (middle assembly), and inspection (assembly). When a small assembly is assembled by cutting and welding an iron plate in the subassembly, And then combined with other assemblies to produce larger assemblies, which are then transported to the dock for comparison. Of course, the assemblies are assembled into the next assemblies while the assemblies are moved to the fixed platens when the assemblies are assembled. In this case, since a plurality of assemblies are transferred to the above-mentioned platen and assembled into various assemblies, the assemblies have various shapes, so that it is necessary to efficiently arrange the platen efficiently. That is, the operator confirms the shapes of the above-described assemblies and places the new assemblies in the vacant spaces according to the shapes of the assemblies currently placed on the base.

However, when various types of assemblies are arranged on the platen as described above, when the operator manually arranges the shape and size of the assemblies between the assemblies by manual operation, The assemblies must be moved to a different place when the assembly of the assemblies is incorrect.

FIG. 1 is a schematic view showing a method of arranging assemblies on a base of a ship drying workshop according to the related art, and various kinds of assemblies used in assembling, designing, mounting and the like are stored in a server computer to form a standard assembly. In other words, when standardizing various types of assemblies placed on the base in shipbuilding, by length, width, and type, and storing them in the server computer, when placing new assemblies on the base, selecting one from the standardized assemblies, So that the assembly can be disposed. For example, in the case of a triangle-shaped assembly, the standardization of the above-described assembly can set the coordinates (0.0, 0.0, 0.0) for each of the vertexes p1, p2 and p3 to specify the size and shape.

This prior art has the advantage that the standard form and size of the assemblies are defined and stored in the server computer as standard assemblies, and when the assemblies are placed on the base, the interference of the assemblies and the interference of the assemblies and facilities can be grasped.

The present invention is a further refinement of the related art as described above. The present invention extracts a bitmap image (an assembly projection shape) using information of an assembly specified in model data designed in a production design using a CAD, stores the extracted bitmap image The object of the present invention is to provide a method of automatically arranging an assembly of fixed platens using model image information when a ship is dried, in which productivity can be improved by improving the rotation rate of a platen by optimally arranging the platens on a work table using a program.

In order to accomplish the above object, the present invention provides a method of operating a ship design program, including: operating a ship designing program such as Tribon; Extracting assembly information from the design program; Creating an SPF file based on the extracted assembly information; Generating a bitmap file from the SPF file; And operating the base batch process based on the generated bitmap file.

According to the present invention, assemblies having various shapes and physical properties to be assembled in a platen are grouped into similar groups, then detailed processes occurring in the work steps are identified, work periods are set in consideration of the work amounts of the respective processes, When the new assembly is placed on the table after storage, it is possible to accurately arrange the assembly and schedule by simply placing the table in the current table state reflecting the standardized assembly information

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

2 is a diagram showing a process of extracting an image from the production design model data of the present invention.

In step S10, a ship design program such as Tribon (Design CAD Model Data) is operated. In step S20, the assembly information is extracted from the design program. The assembly information is a 3D value. In step S30, an SPF file, which is an assembly information file, is created based on the extracted assembly information. In steps S40 and S50, a bitmap file which is an assembly image file is generated from the created SPF file. In step S60, the base batch program is activated based on the generated bitmap file.

In step S40, the bitmap file is read by a program that converts an SPF file into a bitmap file, and then the content of the SPF file is analyzed using an SPF parser, and two-dimensional information Which extracts the slope information considering the workability of the production. The bitmap file, which is the assembly image information, contains detailed information as much as the assembly information is generated from the design CAD model data, and reflects the information about the structure of the assembly 100%.

3 is a view showing a method of disposing an assembly on a specific surface of a ship drying workshop. When placing the assembly on the table, as shown in the figure, the reference points such as the first reference point, the second reference point, the third reference point, and the fourth reference point are set in advance, and then the assembly is arranged based on the reference point. When the user places the assembly on the table with the mouse on the computer screen, the position of the assembly at that time is also used as a reference point. The parts that should not touch the assembly at the time of placement of the table should be displayed after displaying the constraint line and not placed when the line is caught. In Fig. 3, A shows an area in which the assemblies overlap. On the other hand, when the assembly is placed on the table, the assemblies are placed on the table from the preassigned assembly on the basis of the "priority" of the preassigned assembly. . The assembly work is calculated taking into consideration both time and space. The time is calculated by taking the time required for the work performed on the work surface, the period for replacing the assembly on the work surface, and the time interval for the work surface Space refers to information such as the number of plaques, the size of plaques, and the location of plaques.

The following is a description of the alignment process flow. First, the assembly information is extracted from the design program such as the step Tribon, and the assembly information is obtained (S4100, S4110). Subsequently, a bitmap file is generated from the extracted assembly information to generate an assembly bitmap (S4120, 4130). Subsequently, an assembly list composed of the assembly information and the assembly bitmap is generated, and an assembly list is created (S4140, S4150). Subsequently, at one factory, one of the work bases to be placed on a specific date, for example, the present day, is selected, and then the respective bases are sequentially searched (S4160). Then, it is confirmed whether or not the batch placement for the day is completed (S4170). If the layout is completed today, the current date is changed to the next date (S4180), and the current base is moved to the first base of the next date (S4190). Then, it is confirmed whether or not the table is available for the current date (S4200). If available, it is checked whether there is an assembly working on the current table on the current date (S4210). On the other hand, if it is determined in step S4170 that the placement of the table is not completed today, the flow advances to step S4200 to confirm whether or not the table is available for the current date. In step S4210, if there is no assembly working on the current base of the current date, all the assemblies in the assembly list are sequentially arranged (S4220). If there is no overlap, the current assembly is removed from the assembly list (S4240), and it is confirmed whether the assembly list is empty (S4270). If the overlap is not empty, And terminates. If the assembly list is not empty, the current platen is moved to the next platen (S4280). If an overlap has occurred in step S4230, the assembly is rolled back to the assembly list (S4250), and it is checked whether all the assemblies in the assembly list have been arranged (S4260). Then, If the placement is attempted, the current platen is moved to the next platen (S4280), and the flow advances to step S4170 to confirm whether the platen placement is completed for the present day. On the other hand, if the table is not available on the current date in step S4200 and there is an assembly working on the current table on the current date in step S4210, the flow advances to step S4280 to move the current table to the next table, The flow advances to step S4170 to confirm whether or not the base placement is completed today. On the other hand, if it is determined in step S4260 that all the assemblies in the assembly list have not been arranged, the flow returns to step S4280 to move the current platen to the next platen, and then proceeds to step S4170 to confirm whether the platen placement is completed. If it is determined in step S4260 that no batch is attempted for all the assemblies in the assembly list, the process advances to step S4220.

Fig. 5 shows a flow chart for generating a plazma image. Hereinafter, a flow for generating plazma image is described.

First, the 3D format step data for the assembly is input (S510), and the 3D data and the assembly data are generated by analyzing the step data (S520). In step S530, an image creation object, that is, an object placement target is selected in the assembly list. In step S540, a plane coordinate, that is, a position to be placed on the spot for the convenience of operation is automatically calculated in step S540. If the position is not suitable, the user manually confirms the position (S560), determines the position manually (S560), and corrects the position to check whether the position is proper again (S550). Then, the scale is determined so that the pixel values of the assembly assembly are equal to each other according to the pixel value of the base size (S570). Next, in step S590, the assembly bitmap is generated using the position information as a 2D value (S580). In this way, a platen image is generated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. have.
