Description

Technical Field

[0001] The invention relates to the field of computer-aided design, and in particular to a conversion method, system and storage medium for a core sheet diagram. Background Art

[0002] The core sheet diagram is a schematic diagram used to show the structure and size of the core. Its content includes the cross-sectional diagram of the core and the dimensional parameters of each level of the core. The core sheet diagram plays a guiding role in the actual processing of the core.

[0003] At present, the efficiency of manually drawing core sheet diagrams by staff is relatively low. For example, the production time of a sheet diagram of an ordinary distribution transformer core is more than 30 minutes, and the production time of a main transformer core sheet diagram with many levels and relatively complex sheet types is 45 minutes to 1 hour and 15 minutes. Such efficiency cannot meet the factory's increasing production needs. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a method, system and storage medium for converting a core sheet diagram to solve one or more problems in the prior art.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A method for converting a core sheet diagram comprises the following steps: Obtain core design parameters; Calculate the cross-sectional parameter group and the annotation parameter group according to the core design parameters; Generate a core cross-section view according to the cross-section view parameter group, and annotate corresponding dimensions on the core cross-section view according to the annotation parameter group.

[0006] Further, the core design parameters include the number of high-voltage side stages, the number of low-voltage side stages and the sheet width corresponding to each stage; the annotation parameter group includes the sheet width annotation parameter; The step of calculating the marked parameter group according to the core design parameters comprises the following steps: Determine whether the number of stages on the high-pressure side is greater than that on the low-pressure side. If the number of stages on the high-pressure side is greater than that on the low-pressure side, the slice width annotation parameters of the corresponding slice widths are generated according to the slice widths of each stage on the high-pressure side and the slice widths of the small stages on the low-pressure side; If the number of stages on the high-pressure side is equal to the number of stages on the low-pressure side, the slice width annotation parameters of the corresponding slice widths are generated according to the slice widths of each stage on the high-pressure side.

[0007] Furthermore, the core design parameters also include the thickness corresponding to each level of the core, and the annotation parameter group also includes the level thickness annotation parameters; The step of calculating the marked parameter group according to the core design parameters also includes the following steps: If the number of stages on the high-pressure side is greater than that on the low-pressure side, the level on the high-pressure side that is more than the low-pressure side is defined as the second level, and the same level on the high-pressure side and the low-pressure side is defined as the first level. The corresponding level thickness annotation parameters are generated according to the thickness between each second level and the small level on the low-pressure side, and the corresponding level thickness annotation parameters are generated according to the thickness between each first level and the corresponding low-pressure side level; If the number of stages on the high-pressure side is equal to that on the low-pressure side, the corresponding stage thickness annotation parameters are generated according to the thickness between each stage on the high-pressure side and the corresponding stage on the low-pressure side.

[0008] Furthermore, the annotation parameter group also includes a single-stage thickness annotation parameter, and the annotation parameter group is calculated according to the core design parameters, and the following steps are also included: Determine whether the thickness of each stage on the high-pressure side is the same as the corresponding single-stage thickness on the low-pressure side. If the thickness of each level on the high-pressure side is different from the corresponding single-level thickness on the low-pressure side, the single-level thickness annotation parameters are generated according to the single-level thickness on the low-pressure side that is different from the corresponding high-pressure side, and the corresponding single-level thickness annotation parameters are generated according to the single-level thickness on all high-pressure sides; If the thickness of each level on the high-pressure side is the same as the corresponding single-level thickness on the low-pressure side, the corresponding single-level thickness annotation parameters are generated according to the single-level thickness of all high-pressure sides.

[0009] Furthermore, the step of generating slice width annotation parameters corresponding to the slice widths according to the slice widths of each level on the high-voltage side includes the following steps: Determine the marking length corresponding to each level according to the level number, sheet thickness and preset marking interval of the corresponding level on the high pressure side; Generate slice width annotation parameters according to the annotation length and slice width corresponding to the level.

[0010] Furthermore, before calculating the cross-sectional parameter group according to the core design parameters, the following steps are included: Determine whether the core design parameters include offset. If yes, a cross-sectional parameter group related to the slice width, slice thickness and offset is calculated according to a preset first calculation method; If not, a cross-sectional parameter group related to the slice width and slice thickness is calculated according to a preset second calculation method.

[0011] Further, generating the core cross-sectional view according to the cross-sectional view parameter group, and marking corresponding dimensions on the core cross-sectional view according to the marking parameter group, comprises the following steps: Acquire software parameters, and determine the conversion method based on the comparison relationship between the preset software parameters and the conversion method; Converting the cross-section parameter group into a cross-section specific parameter group and converting the annotation parameter group into an annotation specific parameter group according to the conversion method; The cross-section specific parameter group and the annotation specific parameter group are input into corresponding drawing software to generate the core cross-section diagram and corresponding annotations.

In addition, the labeled data is screened during the drawing process, and some duplicate data is removed, so that the formed core sheet type diagram is more concise without causing information loss.

[0021] A method for converting a core sheet diagram, see Figure 1, including the following steps: S100, obtaining core design parameters.

[0022] The core design parameters include the number of high-voltage side stages, the number of low-voltage side stages, and the width and thickness of each core stage.

[0023] The core is made of multi-stage silicon steel sheet groups. The sheet width of the silicon steel sheet group gradually decreases from the middle of the core to the sides. That is, the sheet width of the middle stage of the core is the largest, which is defined as the main stage. The core parts on both sides of the main stage are the high-voltage side core and the low-voltage side core. The last stage on the high-voltage side and the last stage on the low-voltage side are both defined as the small stage.

[0024] In the core industry, it is generally required that the number of high-voltage side cores is greater than or equal to the number of low-voltage side cores, and when the number of high-voltage side cores is equal to the number of low-voltage side cores, the high-voltage side cores and the low-voltage side cores correspond to each other step by step, and the shapes of the silicon steel sheets constituting the corresponding high-voltage side cores and low-voltage side cores are the same; and when the number of high-voltage side cores is greater than the number of low-voltage side cores, the low-voltage side cores still correspond one-to-one with part of the high-voltage side cores, and the remaining high-voltage side cores that do not correspond to the low-voltage side cores are small levels and cores stacked on the small levels in sequence.

[0025] S200, calculating a cross-sectional parameter group and a marking parameter group according to the core design parameters.

[0026] The cross-section parameter group is applied to the drawing software to display the data of the overall cross-section of the core, and the annotation parameter group is applied to the drawing software to display the data of various annotations of the core.

[0027] In this embodiment, the cross-sectional view parameter group and the annotation parameter group are both coordinate parameter groups.

[0028] Among them, the cross-sectional view parameter group includes multiple cross-sectional view coordinate sets, each cross-sectional view coordinate set corresponds to a certain level of the iron core, and each cross-sectional view coordinate set has two diagonal coordinates, and the two diagonal coordinates under the same cross-sectional view coordinate set correspond to the two diagonal endpoints of the corresponding level of the iron core.

[0029] It can be seen that the calculation of the cross-sectional parameter group is related to the sheet width and sheet thickness of each level of the core. However, since the cross-sectional diagram of the core has two different types, D type and non-D type, D type, such as Figure 2 As shown, the distances from both sides of the high-voltage side core to the center of the main stage are not equal. Figure 3 As shown, the distances from both sides of the high-voltage side core to the center of the main stage are the same. In order to distinguish these two cross-sectional views, the offset parameter is introduced. The offset refers to the distance between the side lines of each level of the high-voltage side core in the D-type core and the side line of the main stage. In this embodiment, the offset is specifically defined as the distance between the right side line of each level and the right side line of the main stage.

[0030] Specifically, calculating the cross-sectional parameter group according to the core design parameters includes the following steps: S210: Determine whether the core design parameters include an offset.

[0031] S220: If the core design parameters include an offset, a cross-sectional parameter group related to the sheet width, sheet thickness, and offset is calculated according to a preset first calculation method.

[0032] S230: If the core design parameters do not include the offset, a cross-sectional parameter group related to the sheet width and the sheet thickness is calculated according to a preset second calculation method.

[0033] The principle of the first calculation method is as follows: First, establish a two-dimensional coordinate system on the cross-section diagram to determine the origin. Second, use the origin as a reference point, determine the two diagonal coordinates of the corresponding level in turn according to the sheet width and sheet thickness of each level of the core, and then summarize the diagonal coordinates to form a cross-section parameter group.

[0034] For example, take the midpoint of the left side of the main stage cross-section as the origin, the length direction of the main stage as the X axis, the thickness direction of the main stage as the Y axis, the width of the main stage as L, the thickness of the main stage as H, the coordinates of the upper left corner endpoint of the main stage as (0, H / 2), the coordinates of the lower right corner endpoint as (L, -H / 2), and the cross-section coordinate set corresponding to the main stage as (0, H / 2: L, -H / 2). The width of the high-voltage side core of the first stage adjacent to the main stage is M, and the thickness is h, then the cross-section coordinate set of the high-voltage side core of this stage is ((LM) / 2, -H / 2: (LM) / 2+M, -H / 2-h).

[0035] The principle of the second calculation method is as follows: First, establish a two-dimensional coordinate system on the cross-sectional view and determine the origin. Second, use the origin as a reference point and determine two diagonal coordinates based on the sheet width and sheet thickness of the iron core of the nearest level to the origin. Third, use the newly generated diagonal coordinates as a reference point and determine two diagonal coordinates based on the sheet width, sheet thickness and corresponding offset of the adjacent level iron core. Repeat the third step until the diagonal coordinates corresponding to all levels of iron cores are generated.

[0036] For example, still taking the midpoint of the left side of the main stage cross-section as the origin, the length direction of the main stage is the X axis, the thickness direction of the main stage is the Y axis, the sheet width of the main stage is L, the sheet thickness of the main stage is H, the coordinates of the upper left corner endpoint of the main stage are (0, H / 2), the coordinates of the lower right corner endpoint are (L, -H / 2), and the cross-section coordinate set corresponding to the main stage is (0, H / 2: L, -H / 2). The sheet width of the high-voltage side core adjacent to the main stage is M, the sheet thickness is h, and the offset is X. The coordinates of the main stage endpoint closest to the high-voltage measuring core of this stage are (0, -H / 2). Now taking the coordinates of this endpoint as the reference point, the coordinates of the upper right corner endpoint of the high-voltage side core of this stage are (X, -H / 2), the coordinates of its lower left corner endpoint are (X+M, -H / 2-h), and the cross-section coordinate set is (X, -H / 2: X+M1, -H / 2-h).

[0037] The annotation parameter group includes sheet width annotation parameters, level thickness annotation parameters and single level thickness annotation parameters.

[0038] The sheet width annotation parameter is used to mark the sheet width of any level of core. Although each level of core has a corresponding sheet width. However, since the low-voltage side core has a corresponding relationship with at least part of the high-voltage side core, in fact, only the low-voltage side core needs to be marked, such as Figure 4 shown.

[0039] Calculating the marked parameter group according to the core design parameters includes the following steps: S240, determining whether the number of stages on the high-pressure side is greater than the number of stages on the low-pressure side.

[0040] S241. If the number of stages on the high-pressure side is greater than that on the low-pressure side, a slice width annotation parameter of the corresponding slice width is generated according to the slice width of each stage on the high-pressure side and the slice width of the small stage on the low-pressure side.

[0041] S242. If the number of stages on the high-pressure side is equal to the number of stages on the low-pressure side, a slice width annotation parameter of the corresponding slice width is generated according to the slice width of each stage on the high-pressure side.

[0042] Judging whether the number of stages on the high-voltage side is greater than the number of stages on the low-voltage side is to judge whether the high-voltage side core and the low-voltage side core completely correspond. If the number of stages on the high-voltage side is equal to the number of stages on the low-voltage side, it is only necessary to mark the sheet width of the high-voltage side core, and completely omit the sheet width marking of the low-voltage side core. If the number of stages on the high-voltage side is greater than the number of stages on the low-voltage side, due to the particularity of the core structure, in addition to marking all the sheet widths of the high-voltage side core, it is also necessary to mark the sheet width of the small-level low-voltage side core, so that the staff can understand which levels the low-voltage side core lacks relative to the high-voltage side core. As for the situation where the number of stages on the high-voltage side is less than the number of stages on the low-voltage side, it means that there is a problem in the entry of the core design parameters, and an alarm is issued.

[0043] The step of generating slice width annotation parameters of corresponding slice widths according to slice widths of each level on the high-voltage side includes the following steps: S243, determining the marking length corresponding to each level according to the level number, sheet thickness and preset marking interval of the corresponding level on the high-voltage side.

[0044] S244. Generate slice width annotation parameters according to the annotation length and slice width corresponding to the level.

[0045] The slice width annotation parameters include two dimension line coordinates and one slice width text coordinate. The slice width boundary coordinate is related to the slice width and thickness of the corresponding level, and the slice width text coordinate is related to the slice width, thickness and annotation length of the corresponding level.

[0046] The calculation method of the marked length of the high-voltage side core is: S=N*Z+Q1, where N is the number of stages corresponding to the high-voltage side core, Z is the preset marking interval, and Q1 is the total thickness of the high-voltage side. The total thickness of the high-voltage side needs to be added with half of the thickness of the main stage core in addition to the sum of the thickness of the high-voltage side core.

[0047] For the convenience of calculation, the marked length of the main stage is also calculated using the above formula, but the number of the main stage needs to be defined as 1, the number of the high-voltage side core adjacent to the main stage is defined as 2, and the number of the remaining high-voltage side cores is increased by one.

[0048] The calculation method of the marked length of the low-voltage side core is: S=Z+Q2, Z is the preset marking interval, and Q2 is the total thickness of the low-voltage side. The total thickness of the low-voltage side needs to be added with half of the thickness of the main core in addition to the sum of the thickness of the low-voltage side core.

[0049] Furthermore, the horizontal coordinates of the two sheet width limit coordinates of the high-voltage side core are the same as the horizontal coordinates of the two diagonal coordinates of the corresponding level core, and the vertical coordinates of the sheet width limit coordinates are the negative value of the total thickness of the current level of the high-voltage side plus the previous level. The horizontal coordinate of the sheet width text coordinate is the middle value of the horizontal coordinates of the two sheet width limit coordinates, and the vertical coordinate is the negative value of the marked length.

[0050] The horizontal coordinates of the two sheet width limit coordinates of the low-voltage side core are the same as the horizontal coordinates of the two diagonal coordinates of the corresponding level core, and the vertical coordinates of the sheet width limit coordinates are the total thickness of the current level of the low-voltage side plus the previous level. The horizontal coordinate of the sheet width text coordinate is the middle value of the horizontal coordinates of the two sheet width limit coordinates, and the vertical coordinate is the marked length.

[0051] Calculating the marked parameter group according to the core design parameters also includes the following steps: S250. If the number of levels on the high-pressure side is greater than that on the low-pressure side, the level on the high-pressure side that is more than the low-pressure side is defined as the second level, and the same level on the high-pressure side and the low-pressure side is defined as the first level. The corresponding level thickness annotation parameters are generated according to the thickness between each second level and the small level on the low-pressure side, and the corresponding level thickness annotation parameters are generated according to the thickness between each first level and the corresponding low-pressure side level.

[0052] S251. If the number of stages on the high-pressure side is equal to the number of stages on the low-pressure side, corresponding stage thickness annotation parameters are generated according to the thickness between each stage on the high-pressure side and the corresponding stage on the low-pressure side.

[0053] The stage thickness annotation parameter is used to annotate the total thickness from a certain stage on the high-voltage side to the corresponding stage on the low-voltage side. When the number of high-voltage side stages is equal to the number of low-voltage side stages, each high-voltage side core has a corresponding low-voltage side core. However, when the number of high-voltage side stages is greater than the number of low-voltage side stages, there will be several high-voltage side cores without corresponding low-voltage side cores. Therefore, these high-voltage side cores are defined as the second level, and the low-voltage side small stage is designated as the corresponding stage of the second-level core, such as Figure 5 shown.

[0054] The step thickness annotation parameters are also composed of three coordinate points, including two step thickness limit coordinates and one step thickness text coordinate.

[0055] The origin is the midpoint of the left side of the main-level cross-section, the length direction of the main level is the X-axis, and the thickness direction of the main level is the Y-axis. The horizontal coordinates of the two level thickness boundary coordinates of the main level are both the main level sheet width, and the two vertical coordinates are half of the main level thickness and the negative of half of the main level thickness; the horizontal coordinate of the main level thickness text coordinate is the sum of the main level sheet width and the preset distance, and the vertical coordinate is 0. The preset distance is set by the staff and must be larger than the size of the annotation text.

[0056] The horizontal coordinates of the two level thickness limit coordinates of other level thickness annotation parameters are the difference between the previous level horizontal coordinate minus the previous level sheet width and the current level sheet width. The vertical coordinate of the level thickness limit coordinate on the low-pressure side is the sum of the previous level vertical coordinate and the current level low-pressure side sheet thickness, and the vertical coordinate of the level thickness limit coordinate on the high-pressure side is the sum of the previous level vertical coordinate and the negative number of the current level high-pressure side sheet thickness. The horizontal coordinate of the level thickness text coordinate is the sum of the previous level horizontal coordinate and the preset distance, and the vertical coordinate is 0.

[0057] Calculating the marked parameter group according to the core design parameters also includes the following steps: S260, respectively determine whether the thickness of each stage on the high-pressure side is the same as the corresponding single-stage thickness on the low-pressure side.

[0058] S261. If the thickness of each stage on the high-pressure side is different from the corresponding single-stage thickness on the low-pressure side, single-stage thickness annotation parameters are generated according to the single-stage thickness on the low-pressure side that is different from the corresponding high-pressure side, and corresponding single-stage thickness annotation parameters are generated according to the single-stage thickness on all high-pressure sides.

[0059] S262. If the thickness of each level on the high-pressure side is the same as the corresponding single-level thickness on the low-pressure side, the corresponding single-level thickness annotation parameters are generated according to the single-level thickness of all high-pressure sides.

[0060] The single-stage thickness marking parameter is used to mark the thickness of the single-stage core.

[0061] Same as the sheet width marking, when the thickness of the low-voltage side core sheet is the same as the corresponding high-voltage side core sheet thickness, then only the single-stage thickness of the high-voltage side core needs to be marked, and there is no need to repeat the sheet thickness of the low-voltage side core. Therefore, it is necessary to first determine whether the sheet thickness of each level on the high-voltage side is the same as the corresponding single-stage sheet thickness on the low-voltage side. Once the sheet thickness of each level on the high-voltage side is different from the corresponding single-stage sheet thickness on the low-voltage side, then the sheet thickness of the high-voltage side core and the corresponding low-voltage side core need to be marked, such as Figure 6 shown.

[0062] The single-level thickness marking parameters include two thickness limit coordinates and one thickness text coordinate. The thickness limit coordinates and thickness text coordinates of the same level of core share the same horizontal coordinate, and the horizontal coordinate is the horizontal coordinate of the level thickness limit coordinate corresponding to the level.

[0063] The ordinate of one thickness limit coordinate of the high-voltage side iron core is the ordinate of the level thickness limit coordinate corresponding to the level, the ordinate of another thickness limit coordinate is the ordinate of the level thickness limit coordinate corresponding to the level minus the corresponding sheet thickness, and the ordinate of the thickness text coordinate is the ordinate of the level thickness limit coordinate corresponding to the level minus the corresponding sheet thickness minus the preset distance.

[0064] The ordinate of one thickness limit coordinate of the low-voltage side iron core is the ordinate of the level thickness limit coordinate corresponding to the level, the ordinate of another thickness limit coordinate is the ordinate of the level thickness limit coordinate corresponding to the level plus the corresponding sheet thickness, and the ordinate of the thickness text coordinate is the ordinate of the level thickness limit coordinate corresponding to the level plus the corresponding sheet thickness plus a preset distance.

[0065] 300. Generate a core cross-section diagram according to the cross-section diagram parameter group, and mark corresponding dimensions on the core cross-section diagram according to the marking parameter group.

[0066] At present, common 2D drawing software include CAXA, AutoCAD, etc. Different drawing software may have different requirements for parameter formats. Therefore, in order to cooperate with more drawing software, the core cross-section diagram is generated according to the cross-section diagram parameter group, and the corresponding dimensions are marked on the core cross-section diagram according to the annotation parameter group, including the following steps: S310: Acquire software parameters, and determine a conversion method based on a comparison between preset software parameters and the conversion method.

[0067] S320, converting the cross-sectional view parameter group into a cross-sectional view specific parameter group and converting the annotation parameter group into an annotation specific parameter group according to a conversion method.

[0068] S330, inputting the cross-sectional view specific parameter group and the annotation specific parameter group into corresponding drawing software to generate the core cross-sectional view and corresponding annotations.

[0069] The correspondence between the software parameters and the conversion method is preset by the staff, and the software parameters can be acquired by the computer together with the core design parameters.

[0070] In addition, to avoid the situation where the drawing cannot be produced due to the lack of software parameters, the default drawing software is set in advance, such as setting AutoCAD as the default drawing software. When the software parameters cannot be obtained, the calculator automatically uses AutoCAD's conversion method to convert the section parameter group and the annotation parameter group, and uses AutoCAD to generate graphics and annotations.

[0072] The data acquisition module is used to obtain the core design parameters. The data conversion module is used to calculate the cross-sectional parameter group and the annotation parameter group according to the core design parameters. The graphics generation module is used to generate the core cross-sectional view according to the cross-sectional parameter group, and annotate the corresponding dimensions on the core cross-sectional view according to the annotation parameter group.
