Description
Technical field
Usually, the present invention relates to a kind of system that is used to predict ship section (ship block) fitted position precision, method with and recording medium.More specifically, the present invention relates to a kind of following technology, promptly before the ship section is directly assembled, the dimensional discrepancy of the ship section that calculated in advance will make up, and the size of optimization load segment (erection block), make load segment to be assembled on the root segment (basic block) by disposable assembly technology.
Background technology
A kind of marine structure that comprises ship, the accessory by cutting, processing and welding such as the thick pipe of metal, stud, timber and designing material assembles usually.Ship for example will assemble 100 or multistage more.According to the assemble sequence of finishing ship, at first process and cut according to drawing as a kind of slab of sheet metal, and be welded on the hull part of previous assembling.Then, next piece slab also is welded on this welding portion.Each section of forming hull all is a large scale, and is made of metal, and therefore, by cutting, processing and welding process, its profile may be out of shape.That is to say that it is inconsistent with drawing that its profile may become.In the assembling of ship, carry out dimensional measurement based on load segment and the previous root segment that has been assembled in the hull, load segment utilizes measurement result through being welded to root segment after the processing once more.Hereinafter, " root segment " is meant the ship section that before is assembled in the hull, and " load segment " is meant the ship section with " root segment " combination.
With reference to Fig. 1, the traditional handicraft that is used to predict ship section fitted position precision has been described.
In conventional art, the operator utilizes light wave measurement instrument (1) to measure main part, and root segment is connected to load segment in this main part, and utilizes light wave measurement instrument (2) to measure main part, and load segment is connected to root segment in this main part.The three-dimensional coordinate of the measurement point that light wave measurement apparatus measures operator focuses on.Measurement data corresponding to three-dimensional coordinate is stored in the PDA(Personal Digital Assistant).
Computing machine reads the measurement data of root segment and load segment from PDA, and compares and measures data to calculate the deviation between the measurement point and to export based on the result who tests.
After this, the operator exports sketch and write the three-dimensional numerical value of using text representation in sketch, thereby finishes fitted position precision report (4).The operator utilizes the experience concept of space that three-dimensional numerical value is matched with load segment, so that understand the degree of deformation of load segment, and three-dimensional numerical value is write in the report of two-dimentional fitted position precision, thereby needs the operator to have very high proficiency.
By using the report of fitted position precision, load segment is processed once more thereby cut off load segment.The reprocessing precision of load segment is decided by the accuracy of fitted position precision report.
For assembly technology, in conventional art, load segment is risen and is positioned on the surface in contact of root segment of ship.Then, use the rule measurement to be in the root segment of occasional combination state and the size combinations state of the surface of contact between the load segment.After using actual measured results cutting and process and assemble section, load segment is positioned on the surface of contact of root segment by crane, so that the fixed combination state.Interim and the root segment combination when load segment when the measurement result imprecision, uses crane to repeat the assembly technology of load segment for several times to guarantee the fitted position precision of load segment.
The conventional art of assembling ship section has following shortcoming:
The first, therefore the operator needs operator's proficiency directly according to three-dimensional coordinate value prediction fitted position precision.
The second, because this technology depends on operator's proficiency, so need suitable time and the proficiency that becomes the original operator of raising.
Three, because the operator directly according to three-dimensional coordinate value prediction fitted position precision, so be not easy the numerical value of the load segment in the complex management shape section.
Four, have only the fitted position precision of two sections to predict, and can not judge whether there is gap or overlapping automatically with respect to the deviation that predicts the outcome based on surface of contact.
Five, in the section assembly technology of ship, load segment uses the crane assembling usually.Yet,, increase the service time of crane because of repeating again assembly technology so if the fitted position accuracy prediction of load segment is inaccurate.The crane that uses at present when crane increases service time needs suitable extra cost.
In addition, when under confined state, measuring, the expensive time, and operation is both inaccurate also unstable with cutting operation.
In order to address the above problem, need accurately to measure and manage the size of root segment and load segment, and utilize the technology of the assembly technology of disposable processing and the assembly technology section of finishing.
Summary of the invention
The purpose of this invention is to provide a kind of method, be used on monitor, exporting the 3-D view of root segment and load segment, and the relatively measured value of root segment and the measured value of load segment on the surface of contact of root segment and load segment, and calculation deviation is with prediction fitted position precision, thereby prepare the report of fitted position precision automatically, wherein the deviation chart corresponding to fitted position accuracy prediction result is shown on the load segment.And the present invention has improved the fitted position precision of load segment to reduce the assembly technology time of using crane, assembles and welding technology thereby simplify the ship section.

Thereby fitted position precision with the relative root segment of identification load segment in the measurement coordinate input program of root segment and load segment.
Fig. 5 is an illustration according to the process chart of fitted position precision that is used to predict the ship section of embodiment of the present invention.
When carrying out fitted position accuracy prediction program, the program screen of prediction fitted position precision outputs on the described interface 10.
When selecting root segment from the program screen (in S60 for being), described fitted position accuracy prediction unit 16 reads the segment file of the root segment of selection from described segment file storage unit 14, so that root segment is outputed in the described graphic operation window 30.
When select measuring file from the program screen (in S64 for being), described fitted position accuracy prediction unit 16 reads selected measurement file from PDA, so that each measurement point is outputed to (S66) in the graphic operation window 30.When the position concerns between each measurement point of maintenance, represented measurement point by described graphic operation window 30 demonstrations.
In order to show measurement point on root segment, fitted position accuracy prediction unit 16 is with the reference mark and the measurement point coupling (S68) of root segment.
The method at coupling measurement point and reference mark comprises arranges a plurality of measurement points and a plurality of reference mark, and mates described measurement point and described reference mark.In other words, carrying out the arrangement operation earlier makes the measurement point in the reference mark and the section of being combined in one by one to correspond to each other.As shown in Figure 6, in S66, the measurement point 62 of distribution and be presented in the described action pane 30 with the root segment 61 of reference mark 63 combination.Yet reference mark 63 is difficult to accurately correspond to each other with the measurement point 63 of root segment 61.Preferably, when section was measured under situation about not linking with the reference mark, the position or the direction of design point and measurement point were variant.In this case, before the reference mark was connected to measurement point, reference mark and measurement point made them one by one to correspond to each other based on given standard ordering.For example, can arrange two reference mark and two corresponding measurement points.In dialog box, select two measurement points to be changed with mouse or with the keyboard input.First is starting point, and the basic axle of described two points is passed in second formation.Then, select two reference mark of corresponding selected measurement point, all the other measurement point auto arrangement are with corresponding all the other reference mark.This attended operation can be carried out by several different methods.For example, the operator can manually be connected in the reference mark measurement point or based on a position.In matching process based on a position, when the numerical range of reference mark and measurement point is mated in input, have only the point in the corresponding numerical range to mate, thus coupling reference mark and measurement point.When by before step finish and arrange operation, thereby the reference mark can one by one corresponding measurement point, the measurement point that is arranged in based on the given radius at each reference mark is connected in the reference mark.Described radius is the distance corresponding to the numerical value of given join domain.
The segment file of described fitted position accuracy prediction unit 16 storage root segments, wherein measurement point and 14 combinations (S70) of described segment file storage unit.
Then, described fitted position accuracy prediction unit 16 judges whether to select load segment (S72) on described program screen.
If load segment is selected the judged result (in S72 for being) as S72 extraly, described fitted position accuracy prediction unit 16 execution in step S62 to S70 are to be connected measurement point with selected load segment, and store the segment file of described load segment, utilize this with described measurement point and 14 combinations of described segment file storage unit.
In order to predict the fitted position precision of load segment to root segment, at least one or more a plurality of load segment and root segment, execution in step S62 to S70 of the present invention, thus measurement point is made up in load segment and root segment.When a load segment is connected on the root segment, generate the segment file of a root segment and the segment file of a load segment.Yet, when a plurality of load segments are connected on the root segment, generate the corresponding load segment of segment file.
If have all segment files of root segment and load segment, can carry out the order that load segment is connected to root segment.
On the program screen, select root segment and at least one or more a plurality of load segment, when carrying out a section bind command (among the S74 for being), described dimensional accuracy predicting unit 16 reads the segment file of selected root segment and load segment from described segment file storage unit 14, output to the three-dimensional picture with root segment and load segment in the described graphic operation window 30 of program screen.As shown in Figure 3, show root segment 100 and load segment 200 on the described graphic operation window 30 of program screen.
After the measurement point annexation of setting between root segment and the load segment, described fitted position accuracy prediction unit 16 is according to the fitted position precision of the measurement coordinate Calculation load segment of root segment and load segment.
The setting operation of carrying out the measurement point between coupling root segment and the load segment is with which measurement point of setting assembling and a measurement point coupling in the root segment 100.The operation of the measurement point of coupling root segment 100 and load segment 200 execution that can in all sorts of ways.Particularly, can connect measurement point,, perhaps manually carry out based on the name coupling measurement point of each measurement point based on the position of each measurement point.The method of location matches measurement point based on point is the measurement point that mates load segment 200 automatically, and the matching process of this and root segment 100 is very approximate.
Fig. 7 is illustration is used for based on point location load segment being connected to root segment according to embodiment of the present invention a method synoptic diagram.Utilizing after mouse selects to be connected in the root segment of load segment, set and the input matching range.Measurement point outside the matching range can not match each other.That is to say that the measurement point that only is positioned at the numerical range of corresponding join domain could mate.As a result, the measurement point of root segment 100 can mate with the measurement point of load segment 200.Here, be necessary to select the whether section of insertion of section to be assembled.That is, need to set the relation end to end of section or the internal and external relation of section.Internal and external relation is meant that the center line based on the figure stage casing is arranged in the inboard or the outside with section broad ways (y axle).Here, be necessary to determine whether load segment 200 is combined in root segment 100 in preceding thick view or left and right sides view.
In the method for coupling measurement point based on the name of point, when the name of the root segment 100 and the consecutive point of load segment 200 was identical, measurement point mated automatically.When the measurement of the measurement point of the measurement of load segment 200 and root segment 100 is carried out with same sequence, can carry out this method.
Fig. 8 is that illustration is used for the method synoptic diagram of linkage section manually according to embodiment of the present invention.
The measurement point 210 that manually mates load segment 200 as the user uses this method during with the measurement point 110 of root segment 100.As shown in Figure 8, the user clicks the measurement point that will match each other to select measurement point with mouse in graphic operation window 300, perhaps in dialog box the name of input section name and measurement point with direct coupling measurement point.
When the measurement point of the measurement point of root segment and load segment does not match, carry out linear interpolation or curve interpolation with the measurement point of coupling load segment and the measurement point of root segment.Linear interpolation utilizes two measurement points to generate straight line, and generates XY, YZ and the ZX planar interface of a measurement point of the root segment of passing contiguous load segment, thereby the calculated crosswise of execution and straight line is to generate pseudo-measurement point on load segment.Curve interpolation utilizes three or more measurement point formation curves of load segment, and generates XY, YZ and the ZX planar interface of a measurement point of the root segment of passing contiguous load segment, thus the calculated crosswise of execution and straight line, on load segment, to generate pseudo-measurement point.
After the measurement point coupling of the measurement point of root segment and measuring section, analyze when in S76, finishing when assembling, the operator moves or rotates load segment to adjust the assembling analysis result.
Particularly, shown in Fig. 9 to 12, section moves/rotate command if the operator is the input of fitted position accuracy prediction program on screen, and described fitted position accuracy prediction unit 16 shows the deviation corresponding to the assembling analysis result as vector value.As shown in Figure 9, as the identifier that depends on the degree of deviation, bias vector can be different.In the present invention, identifier can be used employed colouring discrimination in the combination with legend 34, so that operator's a glance just can be discerned the size of deviation.That is to say,, can discern the degree of deviation at a glance if bias vector uses the arrow of the different colours that depends on the deviation size to show.In the drawings, if be shown as ← →, bias vector is represented deviation gap 801, and if be shown as → ←, then bias vector is represented deviation overlapping 802.Bias vector, i.e. the calculated value that obtains by the measurement point between the section relatively is by using the display packing corresponding to the arrow of deviation to obtain.
As shown in figure 10, the direction of the bias vector in each measurement point can be different.In the drawings, the deviation between measurement point is along x direction of principal axis 803, y direction of principal axis 804 and 805 expressions of z direction of principal axis.The method of the direction of appointment bias vector can comprise with mouse selects or draws a measurement point to select several measurement points simultaneously.The user can select the direction of bias vector in the window that ejects subsequently.
With reference to Figure 11, bias vector shows well, is because covered by section in the place that load segment is combined in root segment in figure figure.For fear of the bias vector crested, used the deviation compensation value among the present invention.That is, as shown in figure 12, load segment 200 is one apart from root segment 100 and gives set a distance, and this distance is specified with the deviation compensation value.Therefore, though load segment 200 is to set a distance apart from root segment 100, when section is combined, can be with reference to the compensation value calculation deviate.The deviation compensation value can be set respectively along three direction x, y, z.
The operator can move and rotates load segment 200 according to bias vector, perhaps can be by moving and rotation load segment 200 be adjusted the deviation of root segment 100 and load segment 200.
Simultaneously, the operator can be with the deviation that obtains from S76 process and assemble section 200 once more.Move and the rotation of above-mentioned load segment is not essential step of the present invention.Yet the ship section comprises the part that is difficult to carry out processing once more and carries out the part of processing once more easily.Therefore, be accurate adjustment, move once more and the measurement point of rotation load segment, thereby remove or reduce the deviation of the part that is difficult to carry out processing.The deviation of carrying out the part of processing when relative difficult becomes hour, and the deviation of easily carrying out the part of processing relatively becomes bigger.But, because have the efficient that has improved whole operation than the easy processing of the part of large deviation.
In the present invention, carry out the method that moves section by any or 2 moving methods, and by rotating (one-point-axis-rotation) (displacement) from some axle, 2 axle rotation (two-point-axis-rotation) (displacements) are selected a method of carrying out the rotation section in some axle rotation (1-point-axis-rotation) (angle) and 2 axle rotation (two-point-axis-rotation) (angles).
As shown in figure 13, a bit moving is to point to the mobile load segment of world coordinates axle (x, y, z axle).That is, move selection section to be moved by mouse, and select the moving direction axle.Then, with mouse dilatory correspondent section from described graphic operation window 30, perhaps directly import moving displacement.
As shown in figure 14,2 mobile being meant when moving different shift values, respectively to different direction traverse measurement points 901 and 902.When two end points distortion of section and rotation, 2 are moved of great use.In the same way, select two measurement points of section to be moved, perhaps input and select the section name or measure and call the roll in dialog box from described graphic operation window 30.
The method of rotation section comprises based on the rotation of displacement with based on the rotation of angle.Rotation based on displacement is meant x, the y that uses measurement point to be rotated, the direction displacement rotation section of z axle.Collude spinning solution and use turning axle and rotation angle.But, under the assembling analysis situation of section, use the axial moving displacement of x, y, z at some place to be rotated more effective than using rotation angle.Be divided into two methods based on the rotation of displacement according to the establishing method of turning axle.
