Description

Technical Field

[0001] The present invention relates to the field of nuclear power technology, and specifically to a method and system for naming cable trays in three-dimensional modeling design. Background Art

[0002] In the design process of conventional nuclear power plants, the naming rules of cable tray systems are as follows:

[0003] The hierarchy is WORLD->SITE->ZONE->MAIN->BRAN, as follows: Figure 6 As shown in the figure, the SITE level is set by the system administrator assigned by the Project Office Design Management Office, and other levels are created and managed by electrical professional designers according to design requirements, data hierarchy division and naming rules.

[0004] Currently, the naming rule of ZONE is: plant code + elevation level number + professional code + TM. For example: AA01-K-TM.

[0005] The naming rule of MAIN is: based on ZONE, reduce the function representation and add the pallet matching code + bridge attribute identification. For example: AA01-K-MCT-

[0006] AC00, as shown in Figure X. Among them, there are two types of bridge type codes, "MCT" represents the main pallet, and "LCT" represents the secondary pallet. The main pallet is defined as a pallet with a width of 300mm or more, and the secondary pallet is defined as a pallet with a width of less than 300mm. The bridge attribute identification consists of a safety column, a bridge group, and a serial number, a total of 4 digits. The safety column is represented by a single uppercase English letter, where A represents the safety level A column, B represents the safety level B column, E represents non-safety level earthquake resistance, and N represents non-safety level. The bridge group is represented by a single uppercase English letter, where C represents the control cable bridge and M represents the measurement cable bridge.

[0007] The naming rule of BRAN is: based on MAIN, add the bridge section number, and number them in sequence according to the bridge section (usually 2m or 3m each). Example: AA01-K-

[0008] MCT-AC00-1147A.

[0009] According to the current naming rules, when modeling a bridge, the specific number and spatial position of each bridge section (generally a physical bridge, 2m or 3m section) can be accurately determined. However, because each bridge section needs to be named one by one, the modeling is time-consuming and complicated to operate.

[0010] Moreover, in the MAIN level, MCT and LCT are distinguished according to the 300mm pallet rule. In the actual modeling process, if the bridge is changed in diameter above or below the 300m specification, the bridge naming needs to be changed, which will also increase the modeling time.

[0011] In addition, in the post-processing plant project, 3D modeling does not require the model to accurately distinguish the specific number and spatial position of each cable tray section, which means that there is room for optimization in the current cable tray naming method. Summary of the invention

[0012] The technical problem to be solved by the present invention is to provide a method and system for naming cable trays in three-dimensional modeling design in view of the above-mentioned deficiencies in the prior art. By re-establishing the naming rules for the data levels MAIN and BRAN in the existing naming method and constructing a cable tray naming system, the modeling operation can be simplified, the modeling time can be shortened, and the modeling efficiency can be improved while meeting the modeling precision.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] It should be understood that the specific embodiments and drawings described herein are only used to explain the present invention rather than to limit the present invention.

[0045] It can be understood that each unit and module involved in the embodiments of the present invention may correspond to only one physical structure, or may be composed of multiple physical structures, or multiple units and modules may be integrated into one physical structure.

[0046] It can be understood that, without conflict, the functions and steps marked in the flowcharts and block diagrams of the present invention may occur in an order different from that marked in the drawings.

[0047] It is understood that the flowcharts and block diagrams of the present invention illustrate the possible architectures, functions, and operations of the systems, devices, equipment, and methods according to the various embodiments of the present invention. Each box in the flowchart or block diagram may represent a unit, module, program segment, or code, which contains executable instructions for implementing the specified functions. Moreover, each box or combination of boxes in the block diagram and flowchart may be implemented by a hardware-based system that implements the specified functions, or may be implemented by a combination of hardware and computer instructions.

[0048] It can be understood that the units and modules involved in the embodiments of the present invention can be implemented by software or hardware. For example, the units and modules can be located in a processor.

[0049] The characteristics of the post-processing plant are large spans, many professional equipment rooms, a lot of equipment, and a large amount of cables. The white area corridor is a key location, where various pipelines and cables converge. Correspondingly, many levels and sequences of bridge frames need to be arranged. The general layout plan is to set up main trays along the extension direction of the corridor, and set up secondary trays in each professional equipment room along the way, extending to the vicinity of the equipment in the room.

[0050] Example 1

[0051] like Figure 1 As shown, this embodiment discloses a method for naming a cable tray in a three-dimensional modeling design, including:

[0052] Define the data hierarchy of the cable tray and create the naming rules for the cable tray. The management hierarchy includes MAIN-BRAN. The naming rules of the MAIN hierarchy are: sub-item code and elevation level serial number-professional code and function identification-system category-tray serial number. The naming rules of the BRAN hierarchy are: sub-item code and elevation level serial number-professional code and function identification-system category and tray serial number-BRANCH serial number 1-BRANCH serial number 2.

[0053] Construct a three-dimensional model of the cable tray and determine the management level of the cable tray to be named in the three-dimensional model of the cable tray;

[0054] Name the cable tray according to its management level and the cable tray naming rules.

[0055] Specifically, for a corridor on the same floor and the bridges of the rooms arranged on both sides, there is no need to distinguish between primary and secondary trays. They can be built uniformly under a ZONE-MAIN-BRAN level, which reduces the management level by half compared to the traditional method.

[0056] To build a 3D model of the cable tray, you can use PDMS (Plant Design Management System) software for 3D design, including the establishment of the main tray and the secondary tray, including:

[0057] Establishment of main pallet: The corridor of post-processing plant is characterized by long distance, and the length of a single corridor is usually more than 50 meters. If the traditional model is used for modeling, with a segment every 3 meters, at least 15 straight segments need to be established here. However, this method only requires one straight segment to be established. Then, in the editor mode, drag the bridge control handle to the appropriate length. The time-saving and labor-saving effect of establishing a physical bridge is more obvious when the length is longer, saving more than half of the time.

[0058] Sub-tray establishment: In the new mode, the sub-tray extending to the room only needs to create a new bran branch at the main level of the main channel. Each room only needs to create one or two brans in the same way as the main tray. There is no need to create a new zone-main management level. The model level is reduced and the organization is clearer.

[0059] In some embodiments, Figure 2 , Figure 3 As shown, the sub-item code is 2 uppercase letters, such as AA; the elevation level number is 2 digits, such as 01.

[0060] In some embodiments, Figure 2 , Figure 3 As shown, the professional code is a single capital letter, such as E; the function identifier is a single capital letter, such as N.

[0061] Using the above naming convention, MAIN can be named AA01-EL-N1.

[0062] In some embodiments, the system categories are: N for normal power supply system, B for backup power supply system, and E for emergency power supply system.

[0063] In some embodiments, the bridge serial numbers are: the bridge I serial number of the emergency power supply system is 1, the bridge II serial number of the emergency power supply system is 2, the bridge 1 and 2 serial numbers of the backup power supply system are 1 and 2 respectively, and the normal power supply system serial number is 1.

[0064] In some embodiments, the BRAN serial number 1 consists of two digits, indicating the number of the previous BRAN segment connected to the current BRANC. If the current segment is the first BRANCH, the number of the previous BRANCH is 00; the BRAN serial number 2 consists of two digits, indicating the number of the current BRAN segment, and is arranged in serial number.

[0065] Using the above naming convention, BRAN can be named AA01-EL-N1-00-01.

[0066] Compared with the existing technology (such as Figure 4 As shown), this method re-establishes the naming rules for the data levels MAIN and BRAN in the existing naming method and reconstructs the cable tray naming system. It can simplify the modeling operation and improve the modeling efficiency on the basis of meeting the modeling precision.

[0067] Specifically, the naming rules constructed in this method have made the following innovations:

[0068] (1) Drawing on the concepts of tree trunks and branches, the existing naming rules that restrict naming by section are broken away. Instead, a whole section of the bridge is defined as BRAN01 (generally the bridge in a public channel). Any branch in the bridge is used to derive a new BRAN and is numbered BRAN02. The trunk and branches are clearly defined, and the numbering is concise and clear.

[0069] (2) Convert the existing concepts of MCT and LCT. There is no need to differentiate and name them according to the size of the bridge. Instead, one entire bridge section is defined as BRAN01 (generally the bridge in the public channel) as MCT (MCT is not included in the bridge number), and the remaining branches are defined as LCT (LCT is also not included in the bridge number).

[0070] The effect diagram of the three-dimensional model of the cable tray named by this method is as follows: Figure 5 As shown in the figure, the effect diagram of the three-dimensional model of the cable tray after naming using the existing method is as follows Figure 6 As shown. Figure 5 , Figure 6 It can be seen that the naming rules of this method greatly simplify the original complex naming rule system. According to actual measurements, the modeling time of the same-scale cable tray system is 1 / 3 of the modeling time using the existing old naming rules, which greatly improves the modeling efficiency and reduces labor input.

[0071] Example 2

[0072] like Figure 7 As shown, this embodiment discloses a cable tray naming system in three-dimensional modeling design, which is used to execute the cable tray naming method in three-dimensional modeling design, including:

[0073] The rule formulation unit 11 is used to define the data hierarchy of the cable tray and create the naming rules of the cable tray, wherein the management hierarchy includes MAIN-BRAN, the naming rules of the MAIN hierarchy are: sub-item code and elevation layer serial number-professional code and function identification-system category-tray serial number, and the naming rules of the BRAN hierarchy are: sub-item code and elevation layer serial number-professional code and function identification-system category and tray serial number-BRANCH serial number 1-BRANCH serial number 2;

[0074] A modeling unit 12 is used to construct a three-dimensional model of the cable tray and determine the management level of the cable tray to be named in the three-dimensional model of the cable tray;

[0075] The naming unit 13 is connected to the rule formulation unit 11 and the modeling unit 12 respectively, and is used to name the cable tray according to the management level of the cable tray to be named and the cable tray naming rule.

[0076] Example 3

[0077] like Figure 8 As shown, this embodiment discloses a cable tray naming system in three-dimensional modeling design, including a memory 21 and a processor 22, wherein the memory 21 stores a computer program, and the processor 22 is configured to run the computer program to implement the cable tray naming method in three-dimensional modeling design as described above.

[0078] The cable tray naming system in the three-dimensional modeling design disclosed in Examples 2 and 3 re-establishes the naming rules for the data levels MAIN and BRAN in the existing naming method, and reconstructs the cable tray naming system. This can simplify the modeling operation and improve the modeling efficiency while meeting the modeling precision. According to actual measurements, the modeling time for a cable tray system of the same scale is 1 / 3 of the modeling time using the original old naming rules, which greatly improves the modeling efficiency and reduces labor input.

[0079] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
