Description

Block setting monitoring system and method {SYSTEM AND METHOD FOR MONITORING BLOCK SETTING}

TECHNICAL FIELD The present invention relates to hull block settings, and more particularly to block setting monitoring systems and methods.

In general, shipbuilding is largely the entire process from the field production process including small assembly, heavy assembly, and control, and the field production process including pre-Erection (PE) and dock block loading of the contrasting control block. Is being done through.

In general, the block drying method is used to improve the productivity of the shipbuilding industry.

In the block drying method, first, the hull is divided into tens or hundreds of blocks, and the individual blocks are assembled on the ground, and the manufactured blocks are sequentially mounted on the ship's fleet to assemble into one hull.

The blocks may be assembled at PE workshops to make larger blocks, and blocks such as large transverse bulkheads may be mounted directly on a ship in a dock.

As ship terminology, the degree can mean dimensional accuracy or precision.

In addition, the block coalescing setting may mean welding the set blocks after setting them so that block-to-block registration can be made for block assembly.

In addition, the mounting may mean welding the set block after setting the inter-block matching.

In ship construction, due to the nature of ship production that stacks and connects the intermediate products of assembled blocks, the size of all target blocks from the large block manufactured for loading in the dock to the assembled small block constituting the large block are Is an important quality control target and can maximize the productivity of shipbuilding if integrated block-level prediction and management is possible at the design or manufacturing stage.

However, in the case of large ships, the hull is made up of hundreds of blocks, and in the manufacturing process of these blocks, a plurality of welding deformations, movement deformations, and block temperature difference deformations are generated from the small assembly to the mounting stage, and the measured values are different from the design normal values. Other states, that is, errors can occur, and these process-specific errors can be accumulated or enlarged more and more as small assembling, heavy assembling, contrasting, preloading, PE dock, and dock block mounting, so that the blocks can be loaded at once without re-correction. Can be in a very difficult situation.

Block setting, eg PE setting, is made by placing two control blocks to be preloaded (PE) on the support, comparing them with the normal design values, and calculating the adjustment amount for the setting. By means of detailed adjustments using the transmission, it can mean the task of matching the two contrasting blocks just before mounting.

This setting process can be broadly classified into three categories, including level alignment, block alignment alignment, and block mounting alignment.

Level matching refers to the operation of measuring the level of two control blocks placed on the support, and then adjusting the height between each measuring point using a hydraulic power transmission device. Block alignment alignment refers to the operation of aligning the straightness between two control blocks.

Finally, the block mounting fit refers to the task of opening the proper gap between the two control blocks when welding the two control blocks, so that the PE block can be a normal design value mounting.

The PE setting operation according to the prior art is performed by manual operation of the general shipyard general apparatus by the operator, as shown in FIG.

That is, in the prior art PE setting target block selection operation (S10), when the block assembly schedule of the ship is established, the department in charge of pre-drying according to the schedule selects the PE setting target block and plans the setting schedule.

Subsequently, in the level measurement and analysis operation S11, the level is measured near the support position of the upper or lower portions of each of the two control blocks to be the PE block. The operator calculates the level adjustment through calculation based on manually measured values.

In addition, in the level adjustment operation (support height adjustment) (S12), each control block is lifted larger than the previously calculated level adjustment value by using the hydraulic power transmission apparatus. After adjusting the support height by the level adjustment value, put down each control block using hydraulic power transmission again.

Then, in the level measurement and confirmation operation S13 after adjustment, the level is measured again near the support position of the upper or lower portion of each control block. Check that the level of each support position is correct based on the measured values.

In the conventional block straightness matching operation (S14), the block straightness is adjusted by two methods using a thread and a three-dimensional measuring instrument.

First, in the straightness matching method using a thread, one inner material such as a long paper, a girder, and a frame is selected and marked with a predetermined length at both ends of the corresponding inner material of each control block. Then, connect the thread from the end of the corresponding inner material of one control block to the end of the inner material of the other control block. Each control block is moved using a hydraulic transmission so that the seal and marking line are in a straight line.

On the other hand, in the straightness matching method using a three-dimensional measuring instrument, the main inner material such as girders, frames are selected to measure both ends of the corresponding inner material of each control block. Based on the measured values, a moving value for matching the straightness of the two control blocks is calculated. Check and measure after adjusting by using hydraulic power transmission.

After the straightness is adjusted in this way, the GAP adjustment operation (S15) is performed after the mounting measurement.

In the conventional gap adjusting operation (S15), the mounting of each control block to be PE is measured using a tape measure or the measurement of the main girder and the frame end is mounted as in the previous step using a three-dimensional measuring instrument. Measure it. By calculating the design mounting value of the PE block through the drawing and comparing it with the measured value, the gap value and the setting mounting value in which the weld shrinkage is properly taken into account through experience are obtained. Two control blocks are moved in correspondence with the obtained values using a hydraulic transmission.

Finally, in the final level check measurement operation S16, a level is measured around the support position of the upper or lower portions of each of the two control blocks to be PE to check whether there is any level shift due to the straightness and mounting alignment. If the level is not correct, readjust and readjust the level.

However, the PE setting work according to the prior art has a disadvantage in that setting time is long, and the work result is different according to the operator experience, which makes setting quality management difficult.

In addition, the PE setting work of the prior art has a disadvantage in that the setting accuracy is low and the setting work takes a long time through several setting attempts by manually considering the welding shrinkage to be generated in the block setting.

In particular, in the case of welding shrinkage amount reflects the same value irrespective of steel grade, thickness and gap (gap), there is a disadvantage that the setting expected value is inaccurate, re-correction later occurs. This may show a lot of difference depending on the experience or skill in the deformation, and has been a cause for deterioration of the assembly block.

In addition, the PE setting operation of the prior art has a disadvantage in that it is difficult to perform accurate and rapid setting since it is impossible to simultaneously perform simulation while grasping the movement amount according to the movement of the actual control block in real time.

Embodiment of the present invention is to improve the simulation accuracy and setting accuracy, as the simulation for the block setting can be performed with real-time measurement.

According to an aspect of the present invention, a host computer connected to a wired or wireless network for transmitting information or signals for a plurality of block settings, and having a block setting simulator and a real-time measurement management unit installed therein, and controlled by the host computer. A block setting monitoring system may be provided that includes a real-time measuring device connected to a network, and a server computer coupled to the host computer through the network network to provide block setting information to the host computer or to receive an output result.

According to another aspect of the present invention, the method includes attaching a measurement target, a single sensor, and a wireless hub to a block, selecting a line and a block in a block setting simulator connected to the wireless hub, and forming a three-dimensional block according to the selection. The loading step, the block setting simulator to load the regular design value of the PE target block from the centralized web system of the server computer, and to measure the block using the single sensor and the measurement target; The measurement values obtained by the measurement are loaded into the block setting simulator and matched to have the same coordinate axis as a design normal value, the block setting simulator adjusting the level and straightness, or calculating an optimum gap; The block setting simulator provides a travel value for level adjustment, a travel value for straightness adjustment and an optimum gap. Updated every block movement of the donggap can be provided with a monitoring block sets comprises the step of displaying the measurement point position.

According to the embodiment of the present invention, the block setting simulation is performed by monitoring the entire process of setting the block through real-time measurement, thereby increasing the work efficiency while increasing the accuracy of the block setting.

Embodiments of the present invention can prevent a large amount of time due to the measurement of the same points repeatedly to match or check the level of the blocks and to measure the straightness or mounting.

The embodiment of the present invention calculates the setting amount by a formula reflecting one of the movement of the block and the deformation caused by the temperature, the shrinkage deformation according to the gap of the block, the deformation caused by the deflection, and reflects the setting amount to the corresponding joining surface. Can increase the accuracy.

In the embodiment of the present invention, while performing real-time measurement of the actual collation block, level alignment and straightness alignment between blocks can be performed in the block setting simulator to maximize work convenience, and do not depend on the operator's experience. Work quality can be kept uniform.

In addition, the block setting simulator 123 includes an automatic matching module, a short block error checking module (e.g., a system and method for preparing a dimensional quality inspection result for a hull block (Applicant: Samsung Heavy Industries, Registration No. 10-0941390)), This can be used to convert measured values to have the same axes as the design normal values.

The block setting simulator 123 includes a level alignment unit 125, a straightness alignment unit 126, and a gap alignment unit 127 in the user interface, and the click setting allows for the level alignment, the straightness alignment, and the gap alignment. It may be configured to perform related computer computing operations.

Meanwhile, referring to FIG. 2, the real-time measuring device 130 may be connected to the network 110 to be linked and controlled by the host computer 120.

The real-time measuring device 130 is connected to a plurality of IGPS (Indoor GPS) single sensors 133a and 133b installed at the sensor attachment positions of the blocks 90a and 90b, and to the single sensors 133a and 133b.

In addition, the real-time measuring device 130 is a plurality of IGPS light installed around the block (90a, 90b) so that the sensor local coordinates can be measured in a single sensor (133a, 133b) connected through the wireless hub (132a, 132b). In order to obtain a correlation using the transmitter 131, the measured values obtained from the single sensors 133a and 133b (e.g., the sensor measured values) and the measured values of the measured points of the blocks 90a and 90b, The measurement targets 135a and 135b may be attached to the measurement points of the blocks 90a and 90b.

To this end, the server computer 140 may include a design system for recording and managing three-dimensional CAD block shape information, and a centralized web system for recording and managing a regular design value of a PE target block.

In addition, for the present embodiment, a hydraulic transmission device 80a, 80b connected to the host computer 120 and having a level adjustment function or a position adjustment function whose operation is controlled by the block setting simulator 123 of the host computer 120. ) May be further included.

Hereinafter, the block setting monitoring method according to the present embodiment will be described.

3 is a flowchart of a block setting monitoring method shown in FIG. 2.

Referring to FIG. 3, the block setting monitoring method according to the present embodiment includes a measurement target and sensor attaching step S100, an arc line and a block selection step S110, a three-dimensional block shape loading step S120, and a normal value loading step ( S130), measurement step (S140), measurement value loading and matching step (S150), level matching step (S160), straightness matching step (S170), optimum gap calculation step (S180), block movement value display ( S190), the block movement value display real-time update (S200).

In the step of attaching the measurement target and the sensor (S100), the measurement targets 135a and 135b may be attached to the measurement point positions of the respective blocks 90a and 90b (see FIG. 2).

Thereafter, the IGPS single sensors 133a and 133b and the wireless hubs 132a and 132b may be attached to the sensor attachment positions of the blocks 90a and 90b for 3D real time measurement (see FIG. 2).

In the line and block selection step (S110), the operator executes the block setting simulator to select the corresponding work line and the block in the block setting simulator.

Accordingly, the 3D block shape loading step S120 may be performed.

That is, in the three-dimensional block shape loading step (S120), the three-dimensional CAD block shape information of the PE target block is brought into the block setting simulator 123 (see FIG. 4) from the design system of the server computer, and the block shape ( 90a ', 90b') (see FIG. 4).

In the normal value loading step (S130), the block setting simulator obtains the normal design value of the PE target block from the centralized web system of the server computer.

In the measuring step S140, a three-dimensional large member measuring method using IGPS and a three-dimensional measuring means 134 (see FIG. 2) (for example, a vector bar, etc.) used in the method are used. Measured values of the target may be sent to the block setting simulator.

In the measurement value loading and matching (S150), the measurement values are loaded into the block setting simulator.

The measured value may be in a state where the design normal value and the coordinate axis are different. Therefore, the measured value can be converted to have the same coordinate axis as the design normal value by the automatic matching module of the block setting simulator.

When the coordinate axes between the measured values coincide with each other, the block setting simulator can obtain a correlation between the measured values obtained from the single sensor and the measured values of the measured points of the block.

For example, as shown in FIG. 4, the measured value of the blue point which is the measuring point 91a, 91b of actual block or block shape 90a ', 90b', and the red point measured value obtained from the single sensor 133a, 133b. Can be defined as a correlation with a coordinate transformation matrix.

Here, it is understood that the correlation is defined to output the measured values of the measuring points 91a and 91b through the calculation of the coordinate transformation matrix when the red point measured values obtained from the single sensors 133a and 133b are input as input values. Can be.

Thereafter, the block setting simulator may perform the level fitting step S160.

In the level fitting step (S160), the block setting simulator extracts the measured values used for the level fitting using the height values among the measured values, and obtains a height difference between the measured values and the design normal values.

By using the least-square method using the height difference of each measurement point, the level plane to be the work standard can be obtained, and the height distance from the measured value to the level plane can be determined as the moving values 93a and 93b for level fitting. have.

The movement values 93a and 93b determined as described above may be displayed together with the three-dimensional block shapes 90a 'and 90b' (see FIG. 5).

In the straightness alignment (S170), the block setting simulator extracts a point to be used for the straightness alignment of the block from the measured values, and generates a straightness line based on the two points. The distance value from the extracted points except the two points to the straightness line is obtained. These distance values are the movement values of the block for straightness alignment and can be displayed on the 3D block shape.

In the optimum gap calculation step (S180), the block setting simulator obtains the design mounting value of the PE block from the design normal value and obtains the measurement mounting value from the corresponding measurement value. After calculating the weld shrinkage at the time of PE welding from the deformation inference formula, the optimum gap is calculated from the measurement mount value, the design mount value, and the weld shrinkage amount.

Here, the deformation inference equation can be understood as a prediction equation for a type of shrinkage deformation. The three-dimensional CAD block is used to calculate the factors (eg, plate thickness, steel grade, and initial gap (gap: length between blocks)) for calculating the amount of shrinkage. After extracting from the CAD information DB associated with the shape information and processing the extracted factors through finite element analysis, the shrinkage can be predicted in advance, and then the inference formula containing the three factors mentioned above can be inferred based on the predicted shrinkage. . The inferred deformation inference formula can be corrected and completed to a high degree by verifying through measurement of dimensions before and after welding of actual blocks.

If the deformation type of the block is related to the shrinkage according to the gap, the block-mounted simulator is measured to match the design normal value when calculating the short block error amount at the joining plane in the 3-axis direction between the reference block corresponding to the block and the modified block. Each point group is extracted, the average of one of three axis directions of the first simulation results reflecting the movement and temperature deformation of the extracted measurement point group is maintained, and the current gap between the extracted measurement point groups is maintained as the reference gap. The deformation value may be calculated using a contraction equation according to a reference gap, and the deformation value may be calculated using a contraction equation reflecting a gap increase when the current gap exceeds the reference gap.

Here, the contraction formula according to the reference gap or the contract expression reflecting the gap increase is extracted by using factors such as steel grade, thickness, gap length, etc. to calculate the weld shrinkage considering the gap using the experimental design method, the plurality of by the finite element analysis It may be an inference prediction formula derived by processing the two factors.

In the block movement value display step S190, the movement value for level alignment, the movement value for straightness alignment, and the movement value for the optimum gap may be displayed at the corresponding measurement point position.

In the block movement value display real-time update step (S200), the measured value of the measurement point may be obtained in real time by using the correlation between the single sensor and the measurement point obtained by receiving the measurement value from the single sensor every time the block is moved.

Using the changed measured value, the block movement value can be obtained and displayed again. By using the measured value automatically received from the single sensor without additional measurement work, the changed block movement value can be displayed at the corresponding measurement point position every time the block is moved. Therefore, real-time monitoring is performed by performing block setting and block simulation in real time. can do.

In addition, the movements of the blocks have been obtained through numerical calculations after the current measurement, but in the block setting simulator, the shape and design normal values of the blocks are received from the design system and the server computer, which is a centralized web system. No drawing is required, and the block movement values for level, straightness, and mounting fit are automatically calculated to eliminate human error due to water calculation and displayed at the corresponding measuring point on the 3D block shape. can do.

In addition, through the present embodiment, the measurement data coming in real time can be obtained by automatic calculation in the block setting simulator to obtain a moving value of the block and display it on the 3D block shape to see the PE setting.
