Accompanying drawing explanation
Fig. 1 is the workflow diagram of pipe design of the present invention integration automatic generation method.
Embodiment
Below in conjunction with accompanying drawing and embodiments of the invention to the further detailed description of pipe design integration automatic generation method of the present invention.
As can be seen from Figure 1, first pipe design of the present invention integration automatic generation method comprises to encode to element and to be stored in database, comprise point set information, type collection information, element basis data, element material data are encoded, basis of formation unit, in engineering design process, according to plumbing connection system figure, in 3 D stereo design environment, first orient this pipeline to rise, final position, which namely connect from equipment, which to equipment stop, collect and connect all elements of this pipeline and determine interelement connection logical relation, transfer duct element one by one subsequently, by design starting condition, determine and need transfer duct element coding, according to component numbering find in a database to should element basis unit, thus extract the point set data of this element, type collection data, basic data, material data of description, secondly, to this element in three-dimensional fix, because pipeline reference position is known, first element is directly put into the starting point of pipeline, still first connect pipe string to access again, this is that designer determines, but regardless of any connection, first element coordinate starting point is easy to find, transfer the three-dimensional pattern of the point set data of first element, type collection data generation component, and by this element coordinate setting to starting point, form the three-dimensional stereo model of this element, the basic data of element, material data of description, be contained in the stereoscopic model of this element in the lump.Can calculate this component outlet position coordinates according to point set, type collection data, a rear element is with this exit coordinates for starting point, and all elements in pipeline take out from database by iterative cycles, locate in three dimensions, forms pipeline three-dimensional stereo model.
Owing to comprising design parameter in element basis units all in three-dimensional, the true overall dimensions of each element are all consistent with the parameter in typical conduit design manual.So the program utilizing us to develop is easy to change into working planimetric map, shaft side figure according to projection principle.Extract the individual logarithmic data of each element in the material data of description in each element, basic data, component count device, be easy to generate pipeline material report.
Embodiment 1, component numbering:
Determine coding rule: computer code is carried out to the element in typical conduit design manual, coding point seven parts:
Part I: name code, with 1 English alphabet representative, as:
P represents pipeline; E represents elbow; T represents threeway; It is first-class that R represents size.
Part II: level code, with design pressure or nominal pressure representative, unit is MPa.
Part III: material classification, represents with a capitalization English letter, as |:
C: carbon steel; A: alloy steel; S: stainless steel.
Part IV: material code, represents by 2 bit digital, and one has more than 20 plants material, as: 11 is the material of Q235-A, and 12 is the material of 15CrMOG, and 13 is the material of 20G, and 33 is the material of A335P22.
Part V: pattern code, represents with two capitalization English letters:
S0: seamless external diameter; SI: seamless internal diameter; WO: welding external diameter; EO: external diameter hot pressing; EI internal diameter hot pressing etc.
Part VI: specification code, represents with latus rectum or internal diameter.
Part VII: angle code, this part only has elbow, three to be connected with.
Adopt said elements cryptoprinciple, conventional typical conduit design manual is decomposed, the corresponding coding of each concrete element that design ap-plication is arrived.
As: pressure is 17.6MPa, and temperature is 546 degree, and material is A335P22, and to be the identification code of 90 degree of seamless hot-pressed elbows of 250 be latus rectum: E17.6A33SO250A90.
Wherein E represents elbow, and 17.6 representative pressures are 17.6 MPa, and A represents alloy steel, and 33 to represent material be A335P22, SO representative is seamless external diameter pipe, and 250 to represent latus rectum be that 250mm, A90 represent 90 degree of elbows.
E17.6A33SO250A90 elbow warehouse-in information mainly contains:
1. point set information: the crucial anchor point of element pattern.90 degree of elbows, have three anchor points, can give expression to its pattern location.
2. type collection information: the three-dimensional pattern information of element, 90 degree of elbows, with its point set key point for foundation, encase the pattern of key point formation, represent 90 degree of elbow patterns with right cylinder.Complicated element pattern needs multiple key point, and multiple pattern form, just can indicate its model, and as valve model just needs multiple pattern locator key point, multiple pattern set gives expression to its true model.
3. element basis data, as: connected mode, overall dimensions, wall thickness, substance etc.
4. element material data, some characteristics of referenced elements, as: component type, latus rectum, nominal pressure, design temperature, material etc.
Above-mentioned four kinds of information combination are become the basis unit of these 90 degree of elbows, that is express all design parameter information of this element in typical conduit design manual and be entirely included in this basic unit, this basic metaset pattern, attribute, information are integrated.
Embodiment 2, pipe design:
To design a pipeline, comprise elbow, concentric reducer, threeway etc. in pipeline for example, the material selected is 15CrMOG, and pressure is 4.2MPa, design temperature 455 degree, and pipeline is through concentric reducer, so caliber has two kinds of sizes, DN400 and DN350.The elbow of pipeline all adopts 90 degree of elbows in the design.
According to pipeline elementary diagram and above-mentioned design conditions, binding member coding rule, performs instruction and automatically can find out a secondary component numbering called:
Pipeline: P4.2A12SO400 and P4.2A12SO350.
P represents pipeline, 4.2 representative pressures, and A represents alloy steel, and 12 to represent material be that 15CrMOG, SO represent weldless steel tube 400 and represent inside nominal diameter.
Elbow: E4.2A12SO400A90 and E4.2A12SO350A90.
Threeway: T4.2A12EO400X400A90.
Concentric reducer: R4.2A12SO400X350.
Connecting starting element is elbow, this routine pipeline initial coordinate is (6700, 11800, 10000) east is represented respectively, north, high coordinate figure (value represents with millimeter), pipeline first extends 4 meters eastwards as required in the design, so the coordinate figure connecing first elbow becomes (10700, 11800, 10000), the initial latus rectum of pipeline is 400, so this elbow coding is E4.2A12SO400A90, the data element of this element is recalled from database, resolve through basic meta analysis device, recall the point set data of this element respectively, type collection data, basic data, material data of description, if elbow outlet eastwards upwards, according to point set data, type collection data, generate the stereoscopic model of elbow, by in model orientation to three dimensional space coordinate point (10700, 11800, 10000), now this model has included generally basic data, material data of description.The long 50(of this elbow straight section can find in basic data), so outlet (terminal) coordinate that just can calculate elbow is (10750,11800,10050), this is worth being because elbow exports eastwards upwards, so coordinate points increases by 50 eastwards, upwards increases by 50.So the starting point of next pipe fitting is accurate with this coordinate points, according to each pipe fitting order of connection and on-the-spot cabling requirement, complete whole connections of this pipeline by above-mentioned principle.
The three-dimensional tube stereoscopic model generated, all with design parameter, calls the program of our exploitation, utilizes Three-view projection principle, can extract planimetric map out; Shaft side figure can be generated to a direction projection from solid space; Extract material data of description, the basic data in each element, transfer the individual logarithmic data of each element in component count device, can automatically generate pipeline material report.
