In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe in detail an implementation method of the present invention with reference to the accompanying drawings and embodiments, so that how to apply technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Example one
According to an embodiment of the present invention, a method for managing a pipeline component is provided, and fig. 1 shows a schematic flow chart of a method for managing a pipeline component according to an embodiment of the present invention, and as shown in fig. 1, the method for managing a pipeline component may include: step 110 to step 130.
In step 110, three-dimensional parameter information of the new pipe piece is obtained.
Here, the model three-dimensional parameter information of the new pipeline piece can be obtained by three-dimensional software to perform three-dimensional analysis on the model of the existing pipeline piece, for example, by three-dimensional modeling software Creo. Or, if the existing pipeline piece only has a real object, the existing pipeline piece can be scanned by a three-dimensional scanner to obtain three-dimensional parameter information.
In step 120, a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database is calculated based on the three-dimensional parameter information.
Here, by calculating a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database, it can be determined whether the new pipeline component is similar to or completely consistent with the pipeline component in the pipeline database according to the first similarity.
In step 130, it is determined whether the new pipeline component can be replaced by an existing pipeline component in the pipeline database based on the first similarity, if yes, the existing pipeline component is directly used, and if not, a production demand is initiated according to the new pipeline component.
Here, if it is determined that the new pipe fitting can be replaced by an existing pipe fitting in the pipe database based on the first similarity, meaning that the new pipe fitting and the existing pipe fitting can be used interchangeably, it is not necessary to design a new pipe fitting; and if the new pipeline piece is judged not to be replaced by the existing pipeline piece in the pipeline database, the stored pipeline piece cannot be used for replacing the new pipeline piece, and a new production requirement needs to be initiated.
In this embodiment, whether the new pipeline piece can be replaced by an existing pipeline piece in the pipeline database is determined based on the first similarity, and the existing pipeline piece can be matched when a user designs a new pipeline piece, so that the utilization rate of the existing pipeline piece is improved, and unnecessary increase of material cost is avoided.
Example two
On the basis of the above embodiment, a second embodiment of the present invention may further provide a pipe fitting management method. As shown in fig. 2, the pipe member management method may include steps 210 to 230.
In step 210, three-dimensional parameter information of the new pipe fitting is obtained.
Here, the model three-dimensional parameter information of the new pipeline piece can be obtained by three-dimensional software to perform three-dimensional analysis on the model of the existing pipeline piece, for example, by three-dimensional modeling software Creo. Or, if the existing pipeline piece only has a real object, the existing pipeline piece can be scanned by a three-dimensional scanner to obtain three-dimensional parameter information.
In step 220, a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database is calculated based on the three-dimensional parameter information.
Here, by calculating a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database, it can be determined whether the new pipeline component is similar to or completely consistent with the pipeline component in the pipeline database according to the first similarity.
In step 230, it is determined whether the new pipeline component can be replaced by an existing pipeline component in the pipeline database based on the first similarity, if yes, the existing pipeline component is directly used, and if not, a production demand is initiated according to the new pipeline component.
Here, if it is determined that the new pipe fitting can be replaced by an existing pipe fitting in the pipe database based on the first similarity, meaning that the new pipe fitting and the existing pipe fitting can be used interchangeably, it is not necessary to design a new pipe fitting; and if the new pipeline piece is judged not to be replaced by the existing pipeline piece in the pipeline database, the stored pipeline piece cannot be used for replacing the new pipeline piece, and a new production requirement needs to be initiated.
Therefore, whether the new pipeline piece can be replaced by the existing pipeline piece in the pipeline database or not is judged based on the first similarity, the existing pipeline piece can be matched when a user designs the new pipeline piece, the utilization rate of the existing pipeline piece is improved, and meanwhile, unnecessary material cost is prevented from being increased.
In an alternative embodiment, as shown in fig. 3, in step 220, calculating a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database based on the three-dimensional parameter information may include: step 221 to step 222.
In step 221, geometric characteristic information of existing pipelines in the pipeline database is obtained.
Here, the obtaining of the geometric characteristic information of the existing pipeline may be a three-dimensional geometric analysis of a model of the existing pipeline by using three-dimensional software, for example, the geometric characteristic information of the model of the existing pipeline may be obtained by using three-dimensional modeling software Creo. Or, if the existing pipeline part only has a real object, the existing pipeline part can be scanned by a three-dimensional scanner to obtain the geometric characteristic information. Wherein the geometric feature information includes: at least one of material, diameter, length, bending radius and bending number of the pipeline.
In step 222, a similarity between the three-dimensional parameter information and the geometric feature information is calculated to obtain the first similarity.
Here, the similarity between the three-dimensional parameter information and the geometric characteristic information is calculated, and may reflect the similarity between the new pipeline component and the existing pipeline component in the three-dimensional structure, such as a pipe orifice radius, a pipeline length, a pipeline shape, and the like, so that the first similarity between the new pipeline component and the existing pipeline component in the pipeline database may be obtained, so that a user may search for a similar pipeline.
In an alternative embodiment, as shown in fig. 4, in step 222, calculating a similarity between the three-dimensional parameter information and the geometric feature information to obtain the first similarity may include: step 2221 through step 2228.
In step 2221, according to the three-dimensional parameter information, first pipe diameter information and second pipe diameter information of two pipe orifices of the new pipeline piece are respectively determined.
Here, since the three-dimensional parameter information already includes the pipe diameter information of the two pipe orifices of the new pipe fitting, the first pipe diameter information and the second pipe diameter information of the two pipe orifices of the new pipe fitting, which include the radius or the diameter, can be directly determined from the three-dimensional parameter information. Wherein, the two pipe orifices of the new pipeline piece refer to a starting pipe orifice and a final pipe orifice of the new pipeline piece.
In step 2222, based on the three-dimensional parameter information, first coordinate information and second coordinate information of two end points of the new pipeline piece center line and a first vector direction and a second vector direction respectively related to two pipe orifices of the new pipeline piece are obtained, where the first vector direction and the second vector direction are respectively directions perpendicular to a perpendicular line segment of a plane where the two pipe orifices of the new pipeline piece are respectively located.
Here, the first coordinate information and the second coordinate information of the two end points of the new pipeline center line refer to a start point coordinate and an end point coordinate of the new pipeline center line.
It should be noted that, in step 2222, acquiring, based on the three-dimensional parameter information, first coordinate information and second coordinate information of two end points of the center line of the new pipeline component and a first vector direction and a second vector direction respectively related to two pipe orifices of the new pipeline component may include:
and setting the new pipeline part in a coordinate system according to the three-dimensional parameter information, and determining the first coordinate information, the second coordinate information, the first vector direction and the second vector direction in the coordinate system.
Here, the new pipeline component is set in a coordinate system, the new pipeline component may be re-modeled in the coordinate system through the three-dimensional parameter information, or a three-dimensional model of the new pipeline component may be directly imported into the coordinate system according to the three-dimensional parameter information, and this operation may be completed through three-dimensional modeling software. Then, in the coordinate system, the first coordinate information and the second coordinate information may be acquired, and a first vector direction and a second vector direction may be acquired. It should be noted that the coordinate system includes a rectangular spatial coordinate system and a spherical coordinate system.
In step 2223, third pipe diameter information and fourth pipe diameter information of the two pipe orifices of the existing pipeline piece are determined according to the geometric characteristic information.
Here, since the geometric characteristic information already includes the pipe diameter information of the two pipe orifices of the existing pipe fitting, the third pipe diameter information and the fourth pipe diameter information of the two pipe orifices of the existing pipe fitting, which include the radius or the diameter, can be directly determined from the geometric characteristic information. Wherein, the two pipe orifices of the existing pipeline piece refer to a starting pipe orifice and a final pipe orifice of the existing pipeline piece.
In step 2224, based on the geometric feature information, obtaining third coordinate information and fourth coordinate information of two end points of the center line of the existing pipeline part and a third vector direction and a fourth vector direction respectively related to the two pipe orifices of the existing pipeline part, where the third vector direction and the fourth vector direction are respectively directions perpendicular to perpendicular line segments of the plane where the two pipe orifices of the existing pipeline part are respectively located; and the new pipeline part and the existing pipeline part are arranged in the same coordinate system in a consistent manner.
Here, the methods of obtaining the third coordinate information and the fourth coordinate information and obtaining the third vector direction and the fourth vector are the same as the methods of obtaining the first coordinate information and the second coordinate information and obtaining the first vector direction and the second vector direction, and are not described herein again.
In step 2225, the similarity of the corresponding pipe orifice radii between the new pipe fitting and the existing pipe fitting is calculated according to the first pipe diameter information and the second pipe diameter information, and the third pipe diameter information and the fourth pipe diameter information.
Here, the calculating of the similarity of the corresponding pipe orifice radii between the new pipe orifice and the existing pipe orifice is to determine whether the radii of the pipe orifice at the starting point and the end point of the new pipe orifice and the existing pipe orifice are consistent, and if the pipe orifice radii are too large, the pipeline cannot be installed, which indicates that there is no pipe orifice capable of replacing the new pipe orifice in the pipeline database.
In step 2226, the similarity between the two corresponding end points of the center line between the new pipeline piece and the existing pipeline piece is calculated according to the first coordinate information and the second coordinate information, and the third coordinate information and the fourth coordinate information.
Here, since the new pipe and the existing pipe are arranged in the same coordinate system, the similarity between the coordinates of the two ends of the center line between the new pipe and the existing pipe is calculated, and it is determined that the new pipe and the existing pipe are identical in position.
It should be noted that the new pipeline component and the existing pipeline component are arranged in the same coordinate system in the same manner, which includes:
setting the starting position of the pipeline center line corresponding to the new pipeline piece and the existing pipeline piece on the same coordinate point in a coordinate system, and setting the planes of the respective starting pipe orifices of the new pipeline piece and the existing pipeline piece on the same plane in the coordinate system, and
and the pipeline extending direction and the pipeline bending direction of the new pipeline part and the existing pipeline part in the coordinate system are respectively kept consistent.
Here, since the piping member is a three-dimensional object, the inconsistency of the placement manner thereof in the coordinate system may cause the inconsistency of the reference points of the first coordinate information and the second coordinate information and the third coordinate information and the fourth coordinate information, the inconsistency of the first vector direction and the second vector direction, and the third vector direction and the fourth vector direction, and thus the similarity may not be calculated. Therefore, the new pipeline element and the existing pipeline element are arranged in the same coordinate system in a consistent manner, so as to ensure that the new pipeline element and the existing pipeline element are placed in the coordinate system in a consistent manner.
For example, if the starting point position of the pipeline center line corresponding to the new pipeline part and the existing pipeline part can be set at the origin of the rectangular spatial coordinate system, the first coordinate information representing the starting point of the center line of the new pipeline part is (0,0, 0). And setting the planes of the starting nozzles of the new pipeline piece and the existing pipeline piece on an XOZ surface on a rectangular coordinate system, wherein the pipeline extension directions of the new pipeline piece and the existing pipeline piece in the coordinate system extend along the positive direction of a Y axis, and then the first vector direction of the starting nozzle of the new pipeline piece is represented on the Y axis. The fact that the bending directions of the pipelines are respectively kept consistent means that the rotation angle of the pipeline piece can be regulated to rotate clockwise in a right view (XOZ plane along the negative direction of the Y axis) in a space rectangular coordinate system within a range of 0-360 degrees, the bending angle of the pipeline piece is bent clockwise in a top view (XOY plane along the negative direction of the Z axis) of the space rectangular coordinate system within a range of 0-180 degrees.
In step 2227, the similarity of the vector directions of the corresponding nozzles between the new pipe fitting and the existing pipe fitting is calculated according to the first vector direction and the second vector direction, and the third vector direction and the fourth vector direction.
Here, the pipe diameter similarity of the pipe orifices and the similarity of the positions of the pipe orifices are calculated in the above steps, but the pipe orifices actually exist in the direction in the pipe connection, so the vector direction similarity of the corresponding pipe orifices between the new pipe piece and the existing pipe piece is calculated, and the pipe orifice connection direction can be ensured to be consistent.
In step 2228, the first similarity is obtained based on the similarity of the pipe orifice radii, the similarity of the two end points, and the similarity of the pipe orifice in the vector direction.
Here, it can be determined whether the existing pipeline piece can be used in place of the new pipeline piece according to the similarity between the new pipeline piece and the corresponding pipe orifice of the existing pipeline piece, the similarity between the coordinates of the two end points of the corresponding center line, and the similarity between the vector directions of the pipe orifices.
It should be noted that, in the present embodiment, it is determined whether or not the existing pipe member can be used in place of the new pipe member, and only whether or not the existing pipe member can be connected as the new pipe member at the position to which the new pipe member is to be connected is considered, regardless of the shape, bend, and the like of the pipe member. If the starting point of the two end points of the two pipelines is the same as the coordinate of the terminal, the vector direction of the tail end of the pipeline is regarded as replaceable by a small degree.
In an optional embodiment, after step 230, the method may further include:
and connecting the existing pipeline piece capable of replacing the new pipeline piece as the new pipeline piece on the pipeline, and carrying out design specification check on the new pipeline piece on the pipeline to judge whether the new pipeline piece meets the design requirement.
Here, when designing the pipeline, parameters such as bending angle and length of the pipeline are different due to the fact that part of the pipeline is limited by a spatial structure or is matched with different components, such as a compressor, a gas-liquid separator and other key components. Therefore, the pipeline components determined from the pipeline database do not necessarily completely meet the design requirements, and it is necessary to determine whether the new pipeline component meets the design requirements. If not, initiating a design requirement according to the original new pipeline piece.

In step 310, three-dimensional parameter information for the new pipe fitting is obtained.
Here, the model three-dimensional parameter information of the new pipeline piece can be obtained by three-dimensional software to perform three-dimensional analysis on the model of the existing pipeline piece, for example, by three-dimensional modeling software Creo. Or, if the existing pipeline piece only has a real object, the existing pipeline piece can be scanned by a three-dimensional scanner to obtain three-dimensional parameter information.
In step 320, a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database is calculated based on the three-dimensional parameter information.
Here, by calculating a first similarity between the new pipeline component and an existing pipeline component in a preset pipeline database, it can be determined whether the new pipeline component is similar to or completely consistent with the pipeline component in the pipeline database according to the first similarity.
In step 330, it is determined whether the new pipeline component can be replaced by an existing pipeline component in the pipeline database based on the first similarity, if yes, the existing pipeline component is directly used, and if not, a production demand is initiated according to the new pipeline component.
Here, if it is determined that the new pipe fitting can be replaced by an existing pipe fitting in the pipe database based on the first similarity, meaning that the new pipe fitting and the existing pipe fitting can be used interchangeably, it is not necessary to design a new pipe fitting; and if the new pipeline piece is judged not to be replaced by the existing pipeline piece in the pipeline database, the stored pipeline piece cannot be used for replacing the new pipeline piece, and a new production requirement needs to be initiated.
In this embodiment, whether the new pipeline piece can be replaced by an existing pipeline piece in the pipeline database is determined based on the first similarity, and the existing pipeline piece can be matched when a user designs a new pipeline piece, so that the utilization rate of the existing pipeline piece is improved, and unnecessary increase of material cost is avoided.
In an alternative embodiment, as shown in fig. 6, before step 310, the method further includes: the step of pre-constructing the pipeline database specifically comprises: step 301 to step 302.
In step 301, geometric characteristic information of an existing piping component is obtained.
Here, the obtaining of the geometric characteristic information of the existing pipeline piece is consistent with the obtaining of the three-dimensional parameter information of the new pipeline piece, and details are not repeated here.
In step 302, the pipeline database is constructed based on the geometric feature information.
Here, by constructing the pipeline database, the stored pipelines can be subjected to standardized management, and the pipeline pieces can be conveniently searched.

In step 304, based on the second similarity, one pipeline is determined as a standard pipeline from among the pipeline meeting a preset similarity threshold, and only data information of the standard pipeline is retained in the pipeline database.
By calculating the second similarity of the pipe pieces in the pipe database, the pipe pieces that are substantially similar or consistent in the pipe database can be merged to optimize the pipe data. Determining one pipeline piece as a standard pipeline piece from among pipeline pieces meeting a preset similarity threshold means that only one common pipeline piece is reserved from among a plurality of similar or consistent pipeline pieces which can be replaced and used.
