[0002] The source of attribute information required for engineering quantity calculation is currently provided by the design professionals, which is basically in the form of file transfer. This method does not match the function of automatic quantity calculation and needs to be improved.

In addition, because professional design is not for the purpose of quantity calculation, that is, as long as the component attribute information meets the design requirements during design, these attribute information may not be fully obtained on the PDMS design model, so it needs to be completed by some method.

[0056] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0057] It should be noted that the flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor do they have to be executed in the order described. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0058] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0059] like Figure 1 As shown, the present invention discloses a method for calculating engineering quantity, which is applicable to a quantity calculation platform and includes the following steps:

[0060] Step S10: Obtain component data required for engineering quantity calculation in the PDMS component design model and convert it into an SFC data file;

[0061] Step S20: acquiring corresponding component data from other design platforms according to the component data missing from the engineering quantity calculation in the SFC data file;

[0062] Step S30: Generate a quantity calculation model according to the SFC data file, and calculate the engineering quantity based on the quantity calculation model.

[0063] In this embodiment, if Figure 2 As shown, before step S10, the following steps are also included:

[0064] Step S00: According to the component drawings of the engineering quantity to be calculated, the corresponding PDMS component design model is obtained from the PDMS platform, wherein the PDMS platform is a factory three-dimensional layout design management system, and the DMS component design model is a three-dimensional solid model.

[0065] In some embodiments, the step S00 includes:

[0066] Step S001: receiving a user's selection instruction and selecting a component drawing for which engineering quantities need to be calculated;

[0067] Step S002: Determine the major to which the component drawing belongs according to the drawing code, enter the PDMS platform according to the major, and locate the corresponding PDMS component design model under the major.

[0068] Specifically, the drawing codes, professional codes, equipment category codes, material codes, etc. of nuclear power projects are only used in the nuclear power industry. When the drawings uploaded to the engineering document index (IED) system are declared approved and available (work ready, WR for short), the quantity calculation platform first determines the profession according to the drawing code and preset rules. For example, if the 14th / 15th digit of the drawing code BS3SEC25059DIYK43SD is YK, it represents the Em9 instrumentation and control profession. If it is DQ or TX, it represents the Em8 electrical profession. After entering the PDMS platform according to the profession, the design model of the entire project can be displayed. According to the rules, the corresponding work area and model node of the corresponding drawing under the profession can be located, that is, the PDMS component design model, so that the PDMS component design model of a certain component of a certain profession can be obtained.

[0069] In this embodiment, step S10 includes:

[0070] Step S101: Acquire corresponding engineering quantity calculation rules according to the profession to which the PDMS component design model belongs; in some embodiments, the corresponding engineering quantity calculation rules may be acquired according to the profession determined in the above step S002.

[0071] Step S102: Obtaining corresponding component data in the PDMS component design model according to the engineering quantity calculation rule;

[0072] Step S103: Based on the correspondence between the preset profession and the conversion method, the component data is converted into an SFC data file. The SFC data file includes component data for calculating the engineering quantity, including component attributes and attribute information. In some embodiments, the component attributes include coordinates, length, width, height, and material; in some other embodiments, the component attributes are not limited to coordinates, length, width, height, and material. In some other embodiments, the SFC data file also includes other data derived from the PDMS component design model.

[0073] Accordingly, in this embodiment, step S20 includes:

[0074] Step S201: according to the engineering quantity calculation rule, the component attributes of the missing attribute information in the SFC data file are obtained;

[0075] Step S202: According to the correspondence between the preset component attributes in other design platforms, the corresponding attribute information is obtained from other design platforms to be supplemented into the SFC data file, thereby achieving accurate acquisition of attribute information between databases of different design platforms, and synchronous acquisition of multiple attribute information with multiple other design platforms.

[0076] In some embodiments, the server pre-sets the correspondence between component attributes of different systems, and the missing attribute information in the SFC data file can obtain corresponding attribute information in other design platforms based on the correspondence according to the component attributes.

[0077] For example, from the PDMS component design model, assuming that the exported component material is a stainless steel pipe, the component attribute of the stainless steel pipe can be used as a condition to obtain the corresponding attribute information of the stainless steel pipe from other design platforms, such as "post-pickling = yes, degreasing = no, oil flushing = no" in Table 2 below, and the obtained attribute information can be added to the SFC data file.

[0078] Table 2

[0079]

[0080] In addition, component attributes, such as the universality of nuclear power names and codes, can be used to provide a cross-platform way to complete component data, such as on the bulk material (BMMS) platform. For example, the device name obtained from the PDMS component design model, that is, the component attribute, and the corresponding relationship between the device name and the nuclear power generic name, can be obtained from the bulk material (BMMS) platform. The corresponding attribute information of the equipment can also be obtained from the bulk material (BMMS) platform, and the nuclear grade of the pipeline can be found according to the material code on the BMMS platform, etc. This information can be added to the SFC data file synchronously to form a complete calculation book output result.

[0081] In this embodiment, if Figure 2 As shown, the method also includes:

[0082] Step S21: according to other components preset to be paired with the PDMS component design model, data of other components are added to the SFC data file.

[0083] In some embodiments, when exporting SFC data files, some components (such as matching flanges of valves) do not have design models established in the PDMS platform, but in fact, in the nuclear power field, matching flanges are required on the components. To avoid missing component data, some types of valves can be pre-set to require an additional pair of flanges, and the component attributes and attribute information corresponding to the flanges can also be pre-set. When this type of valve is identified, the SFC data file will automatically add the component identification, component attributes, attribute information and default quantity to the additional component data of the valve, thereby ensuring that the component data is complete and accurate.

[0084] In this embodiment, if Figure 2 As shown, the method also includes:

[0085] Step S40: Write the calculation result into the corresponding quantity column of the engineering quantity calculation sheet, and write the component data into the corresponding project characteristic column of the engineering quantity calculation sheet to complete the engineering quantity calculation sheet and output a complete engineering quantity calculation sheet.

The PDMS platform is a factory three-dimensional layout design management system, and the DMS component design model is a three-dimensional solid model.

[0092] In some embodiments, the model acquisition module includes:

[0093] A selection module is used to receive a user's selection instruction and select a component drawing for which engineering quantity calculation is required;

[0094] The positioning module is used to determine the major according to the drawing code of the component drawing, enter the PDMS platform according to the major, and locate the corresponding PDMS component design model under the major.

[0095] Specifically, the drawing codes, professional codes, equipment category codes, material codes, etc. of nuclear power projects are only used in the nuclear power industry.

For example, if the 14th / 15th digit of the drawing code BS3SEC25059DIYK43SD is YK, it represents the Em9 instrumentation and control profession. If it is DQ or TX, it represents the Em8 electrical profession. After entering the PDMS platform according to the profession, the design model of the entire project can be displayed. According to the rules, the corresponding work area and model node of the corresponding drawing under the profession can be located, that is, the PDMS component design model, so that the PDMS component design model of a certain component of a certain profession can be obtained.

[0099] The data conversion module is used to convert the component data into an SFC data file based on the correspondence between the preset profession and the conversion method. The SFC data file includes component data for calculating the engineering quantity, including component attributes and attribute information. In some embodiments, the component attributes include coordinates, length, width, height, and material; in some other embodiments, the component attributes are not limited to coordinates, length, width, height, and material. In some other embodiments, the SFC data file also includes other data derived from the PDMS component design model.

[0100] Accordingly, in this embodiment, the missing supplement module includes:

[0101] The attribute acquisition module is used to obtain the component attributes of the missing attribute information in the SFC data file according to the engineering quantity calculation rules;

[0102] The information acquisition module is used to obtain corresponding attribute information from other design platforms according to the corresponding relationship between preset component attributes in other design platforms, so as to supplement it into the SFC data file, thereby realizing the accurate acquisition of attribute information between databases of different design platforms, and can also realize the synchronous acquisition of multiple attribute information with multiple other design platforms.

[0103] In some embodiments, the server pre-sets the correspondence between component attributes of different systems, and the missing attribute information in the SFC data file can obtain corresponding attribute information in other design platforms based on the correspondence according to the component attributes.

[0104] For example, from the PDMS component design model, assuming that the exported component material is a stainless steel pipe, the component attribute of the stainless steel pipe can be used as a condition to obtain the corresponding attribute information of the stainless steel pipe from other design platforms, such as "post-pickling = yes, degreasing = no, oil flushing = no" in Table 2 below, and the obtained attribute information can be added to the SFC data file.

[0108] In addition, component attributes, such as the universality of nuclear power names and codes, can be used to provide a cross-platform way to complete component data, such as on the bulk material (BMMS) platform. For example, the device name obtained from the PDMS component design model, that is, the component attribute, and the corresponding relationship between the device name and the nuclear power generic name, can be obtained from the bulk material (BMMS) platform.

[0111] In some embodiments, when exporting SFC data files, some components (such as matching flanges of valves) do not have design models established in the PDMS platform, but in fact, in the nuclear power field, matching flanges are required on the components. To avoid missing component data, some types of valves can be pre-set to require an additional pair of flanges, and the component attributes and attribute information corresponding to the flanges can also be pre-set. When this type of valve is identified, the SFC data file will automatically add the component identification, component attributes, attribute information and default quantity to the additional component data of the valve, thereby ensuring that the component data is complete and accurate.
