Description

Technical Field [0001] The present invention relates to a weight information verification system for each block in ship design information,

The present invention can prevent the occurrence of safety accidents such as dismantling of the installation of the equipment installed in the block or dropping and dropping the block as the corresponding block is unbalanced during transportation of the block for ship building To a system for verifying weight information of each block in ship design information.

Generally, large ships in shipyards are constructed by combining multiple blocks. In other words, the ship is divided into a plurality of blocks and produced, and the blocks thus manufactured are combined according to design, thereby completing the ship.

On the other hand, a variety of equipments are individually mounted on the block which is separately manufactured. The above-mentioned equipment may be various kinds of mechanical equipment, electrical equipment, and wooden equipment installed so that the ship can operate and operate normally. At least one of the equipment is mounted on one block to constitute the weight of the block.

The blocks are separately manufactured and transported to a dock in general for drying the ship using the block, respectively, and then assembled according to the design. Here, the block has a weight of several tons or tens of tons in addition to the mounted equipment, and a specially designed crane is used for transportation to a specific point according to the design.

As mentioned above, since the block immediately before assembly is mostly equipped with most of the equipment for ship building, it is relatively heavy, and since the assemblies are not fully assembled, the mounting state of the equipment is relatively unstable. Therefore, when the block is transported to the specific point according to the design, a sudden tilting may cause the weight to deviate. In this case, the equipment mounted on the block may not be able to overcome the weight. In addition, due to the movement of the equipment, the center of gravity of the block may change and the fixed state of the block with the crane may become unstable. As a result, the block may be separated from the crane and fall down.

In order to prevent the above-mentioned accident, it is more important to level the block when transporting the block. For this purpose, it is important to arrange the crane, which is a means of transporting the block, and the installation position of the lifting lug.

On the other hand, in order to match the arrangement of the crane, the type of the lifting lug, the application quantity and the installation position, it is necessary to prioritize the weight information of the block accurately. However, when the conventional ship design information is converted into a DB, the weight information of the block is limited to simply numerical data, so there is a limit to checking the weight distribution state of the block in three dimensions.

As a result, the crane and the lifting lug can not be placed on the ground in the field, and the block must be transported on the basis of the worker's sense. Therefore, there is a problem that the risk of safety accident as well as the efficiency of the work should be maintained.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an apparatus and a method for quickly arranging a crane and a lifting lug during block transportation in a field through accurate weight information management of a block equipped with a fitting. A technical object of the present invention is to provide a system for verifying weight information of each block in ship design information, which can reliably carry stable transportation work, and can grasp wrong weight information in advance and check errors of ship design information in advance.

According to an aspect of the present invention,

A ship design information DB storing shape information having coordinate values in 3D format, drying process information, and ship design information including information on weight for each ship block composed of the main body and the equipment;

A reference information DB having a block area DB for determining a range of a block area with corresponding coordinate values of the block body and storing the range as reference information; And

A weight information generation module that generates weight information of the verification target block, which is made up of information on coordinates and weight of a verification target block, from the ship design information database; A verification device having a weight information verification module for searching the database for comparison with the weight information and for checking whether there is an error;

A weight information verification unit for each block in the ship design information.

In the present invention, it is possible to grasp whether the ship design information is erroneous beforehand so that the block can be corrected and supplemented before the block is assembled, and the position of the crane and the lifting fixing lug for efficiently transporting the block can be precisely checked, The effect of the block is to compensate for the loss of stability during transport.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, It will be possible. The present invention is capable of various modifications and various forms, and specific embodiments are illustrated in the drawings and described in detail in the text. It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a verification system according to an embodiment of the present invention. Referring to FIG.

The verification system according to the present invention includes a ship design information DB 10 for storing ship design information, a reference information DB 20 for storing reference information for verifying the weight information of the block to be verified, And a verification device 30 for generating information.

The ship design information DB 10 is a device for storing ship design information, and the shape information for the ship is stored as data having coordinate values in 3D format. In the embodiment of the present invention, CAD may be applied to an application that operates the 3D format data, but various known and common applications for editing and processing 3D images may be applied.

Next, in addition to the above shape information for the ship, the ship design information DB 10 stores 'drying process information' and 'work type information' for drying the ship concerned, 'specific material information about constituent materials' And the like.

As a result, the ship design information DB 10 stores all the design information necessary for building a specific ship.

The reference information DB 20 is a device for storing reference information for verifying the weight information of a block to be verified specified by the operator and includes a process classification DB 21, a reference weight DB 22, a block region DB 23, And an information DB 24.

The process classification DB (21) stores process information in which the ship building process is subdivided, and confirms whether the classification target of the block to be identified specified by the operator is correct. When the operator designates the target block by process, To be classified. More specifically, a large ship is usually completed by combining 250 blocks. Since most of these blocks are similar in shape and structure except for the head and the stern blocks, the operator can not easily distinguish them by the shape and shape of the block. Therefore, by linking and managing the ship building process and the block applied at this time, the operator can easily retrieve the reference information of the block corresponding to the verification target block, thereby reducing the possibility of error in the block verification.

The reference weight DB 22 is a device for setting and storing, on a block-by-block basis, valid weight values to be checked at the time of verification among pieces of equipment mounted on a block by an operator, and the effective weight value can be arbitrarily set by an operator as needed. For reference, the effective weight value will be relatively small when the block to be checked is composed only of small weight equipment, and when the block to be verified is composed only of large weight equipment, the effective weight value is relatively small It will be big.

The block area DB 23 stores reference information as a comparison reference for the weight information of the block to be verified. The block area DB 23 stores not only the coordinate value, the weight, the position value of the center of gravity, Part name, part description, and the like. Here, the reference information stored in the block area DB 23 may be generated on the basis of the ship design information of the ship design information DB 10, or may be generated based on the actual measurement result of the block.

The management information DB 24 is a device for storing information on a person who installs and manages equipment for each block. The management information DB 24 is updated and managed in real time so as to notify the person in charge of the error and confirm the error.

The verification device 30 includes a weight information generation module 21 for searching the ship design information DB 10 for information about the 3D coordinate value and the weight of the verification target block to generate weight information of the verification target block, A weight information verification module 32 for comparing the weight information with the reference information of the block stored in the block area DB 23 to check whether there is an error and a verification result management module 33 for managing the history of the verification result do.

The weight information generation module 31 searches the ship design information DB 10 for information about the 3D coordinate value and the weight of the block to be confirmed and generates weight information about the total weight of the block and the position value of the center of gravity do. Here, the worker (the searcher) who generates the weight information can search the block to be inspected more quickly and efficiently because the search operation can be performed according to the construction system of the ship or the drying process of the ship. For reference, the ship building process and the like are systematically stored in the process classification DB 21, and the blocks stored in the ship design information DB 10 and the block area DB 23 are systematically stored.

The weight information verification module 32 compares the weight information of the verification target block generated by the weight information generation module 31 with the corresponding reference information of the block area DB 23 to be compared with the verification target block, Whether or not the weight information of the block to be verified is erroneous is checked based on the reference information. At this time, the positions of the weight and the center of gravity, which are information included in the weight information of the block to be confirmed, are also checked.

The verification result management module 33 generates and manages the verification history information of the weight information verification module 32. If an error is confirmed in the verification process, the verification result management module 33 searches the management information BD 24 for the person in charge of the corresponding block, So that the error can be checked and corrected. For reference, the notification means of the verification result management module 33 may be various such as e-mail, SMS, messenger, and the like.

In addition, the verification result management module 33 transmits the verification history information to an aggregation department or the like that calculates the loading weight so that the loading can be performed by the loading block, by point, by function, and by part.

3 is a perspective view showing an embodiment of a ship building block carried in accordance with the verification method according to the present invention. Referring to FIG. 2, Will be described in detail.

S10; Vessel design information configuration step

Ship design information, which is basic information for ship construction, is stored in the ship design information DB 10. As described above, the ship design information includes data having coordinate values in 3D format for each block corresponding to the shape information of the ship, information on drying process information, work type information, material information about the construction material, weight and the like do.

Here, the coordinate values of the block-by-block 3D format are coordinate values for the main body 110 constituting the block 100 of the ship and coordinates for the positions of the fittings 121, 122, 123 and 124 mounted on the main body 110 Value. The information on the weight is information on the weight of the block 100 and the weight of each equipment 121, 122, 123 and 124.

Since the ship design information DB 10 is naturally manufactured for ship construction, detailed description of the ship design information is omitted.

S20; Standardization Information Standardization Step

The coordinate values of the body 110 of the block 100 stored in the ship design information DB 10 are confirmed to determine a block area and standardize the block area.

As described above, since the coordinate values for the main body 110 are in the 3D format, the stereoscopic block area is determined and recorded in the block area DB 23. In this embodiment, the main body 110 of the block 100 is in the form of a hexahedron composed of the outer plate 111 and the support base 112, and four pieces of equipment 121, 122, 123, and 124 are mounted on the main body 110, And 3D coordinates of the body 110 of the block 100 are stored in the block region. Subsequently, the first equipment piece 121 is a reinforcing panel for reinforcing the outside sheathing 111. The third equipment piece 123 is a partition wall separating the adjacent block from the first equipment piece 121. The second and fourth equipment pieces 122, Machinery.

On the other hand, the process classification DB 21 stores process information on the shipbuilding process based on the ship design information of the ship design information DB 10. [ Therefore, it is possible to relatively easily search the reference information for the block to be checked according to a predetermined classification system, and it can be determined whether the weight information for the verification target block inputted for verification is the constituent block of the ship.

In the reference weight DB 22, effective weight values set by the operator for each block 100 are stored.

In the management information DB 24, information of the person in charge designated for each block 100 is stored.

S30; Step of generating check target weight information

The weight information generation module 31 selects the check target block 100 from the ship design information DB 10 and controls the position of the block 100 and the pieces of equipment 121, 122, 123 and 124 Weight information including coordinate values that can be confirmed and information about the weight of the block 100 and the equipment 121, 122, 123, and 124 is generated.

The weight information may include a position value G of the center of gravity of the block 100 to be verified. The position value G of the center of gravity is utilized to match the placement of the crane, the type of the lifting lug, the application quantity, and the installation positions A, B, and C at the time of carrying the check target block 100.

The weight information generation module 31 selects only the fittings 123 and 124 having the effective weight value or more of the corresponding block 100 among the fittings 121, 122, 123 and 124 by checking the reference weight DB 22 And reflects the weight information. As a result, in the present embodiment, the weight information of the pieces of equipment 123, 124 included in the weight information of the verification target block 100 will be the weight of the third equipment 123 and the fourth equipment 124.

For reference, the selection of equipment pieces having an effective weight value or more may be made selectively. That is, all of the installed equipment 121, 122, 123, and 124 may be checked to check whether the block 100 is faulty. Alternatively, only the equipment 123, 124 having a valid weight value or more may be checked It is possible.

S40; Weight information verification step

The weight information verification module 32 checks whether or not the weight information of the verification target block 100 generated by the weight information generation module 31 is error based on the block area which is the reference information of the corresponding block in the block area DB 23 do. That is, it is checked whether or not the coordinate values of the block area as the reference information and the main body 110 coincide with each other, whether the equipment 123, 124 belongs to the block area as the reference information, I will check whether.

The position of the equipment 123, 124 corresponding to the effective weight value is obtained by calculating the center point position of the equipment 123, 124. To be more specific, the fittings 123 and 124 have respective unique shapes, and the outer points of the ship design information DB 10 are accurately shown and stored as 3D coordinate values. Accordingly, the center point position of the equipment 123, 124 can be calculated based on the outline point.

The calculated center point position is regarded as the position of the equipment items 123 and 124 and the weight information verification module 32 determines whether the corresponding equipment items 123 and 124 are reference information of the corresponding block 100 Check whether it is within the block area.

The weight information verification module 32 calculates the weight of the verification target block 100 by using the weight of the main body 110, the information about the weight of the fittings 123 and 124 and the center point position of the fittings 123 and 124 The central coordinate value G 'as shown in the figure is converted into the 2D coordinate value belonging to the plane of the block 100 by checking the position value G of the center, .

As a result, if the lifting lug is disposed at the vertex position of the polygon having the center coordinate value G 'as its center of gravity, the object block 100 can be stably transported without tilting. Of course, since the lifting lug is installed at the vertex position, it is a matter of course that the vertex position should be a point intersecting the support stand 112. For reference, in the embodiment of the present invention, three lifting lugs (A, B, C) are disposed at the vertex positions of the triangle having the center of gravity G 'as the center of gravity. However, the present invention is not limited thereto, and the number and position of the lifting lugs may be variously modified.

On the other hand, the verification result management module 33 generates and manages the verification history information of the weight information verification module 32. If an error is confirmed during the verification process, the management result information management module 33 searches the management information BD 24 for the person in charge of the block, So that the error can be confirmed and corrected.

In addition, the verification result management module 33 transmits the verification history information to an aggregation department or the like that calculates the loading weight so that the loading can be performed by the loading block, by point, by function, and by part.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
