[0039] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0040] The first aspect of this invention provides an automatic terminal wiring diagram generation method, which is an automatic terminal wiring diagram generation method based on 3D software, such as... Figure 1 As shown, it includes:

[0041] Step 1: Obtain the equipment attribute information of each electrical device in the electrical system and the attribute information of multiple terminal blocks on the electrical devices.

[0042] In this embodiment of the invention, the above-mentioned information of the electrical system is obtained from the CAD drawings provided by the manufacturer. Specifically, the terminal table of the electrical equipment is extracted from the CAD drawings provided by the manufacturer to obtain the attribute information of multiple terminal blocks on the corresponding electrical equipment, and then stored and recorded. For example, the storage and recording are performed in EXCEL format.

[0043] Furthermore, this embodiment of the invention also extracts equipment attribute information of electrical equipment from CAD drawings provided by the manufacturer, specifically extracting electrical circuit models and terminal definitions, whereby the electrical circuit model mainly extracts the name, shape information, and location information of the electrical equipment. The extracted equipment attribute information is then stored and recorded, for example, in EXCEL format.

[0044] This invention uses the automatic generation of terminal wiring diagrams for a hydropower station electrical system as an example to illustrate the effectiveness of the method. The business process for terminal wiring in a hydropower station electrical system is as follows: Figure 2 As shown, the terminal block table of the electrical equipment extracted from the CAD drawings provided by the manufacturer is as follows: Figure 3 As shown, this terminal table is to be imported into the 3D software.

[0045] Before the information obtained in step 1 is entered into the 3D software to form equipment that the 3D software can recognize, the type of electrical equipment and the type of cable need to be specified in accordance with the electrical design rules, and the corresponding extensions are implemented in the software.

[0046] This invention defines a library of terminals and accessories in 3D software, including different types of terminals, connectors, cables, etc. This library serves as the basis for selection, enabling automated wiring and drawing in subsequent steps.

[0047] Step 2: Construct the logic reference diagram of the electrical system, and input the equipment attribute information and terminal block attribute information of the electrical equipment into the logic reference diagram to obtain the logic structure diagram, which specifically includes:

[0048] Step 2.1: Based on the hierarchical relationship within the electrical system, construct a tree-like logical reference diagram of the electrical system.

[0049] In this embodiment of the invention, before inputting the equipment attribute information and terminal block attribute information of the electrical equipment into the 3D software to form equipment that can be recognized by the 3D software, it is first necessary to establish a logical reference diagram of the electrical system in the 3D software. This logical reference diagram presents a tree structure with parent nodes and child nodes according to the hierarchical relationship within the electrical system, so that the equipment attribute information of the electrical equipment and the attribute information of multiple terminal blocks on the electrical equipment obtained in step 1 can be input into the corresponding nodes according to the hierarchical relationship, thereby making the hierarchical structure of the electrical system inside the 3D software the same as the hierarchical structure of the electrical system in the CAD drawings provided by the manufacturer.

[0050] Step 2.2: Enter the equipment attribute information of each electrical device and the attribute information of multiple terminal blocks on the electrical device into the corresponding positions in the logic reference diagram to obtain the logic structure diagram of the electrical system.

[0051] For example, the present invention first selects a schematic diagram for reconstruction in 3D software, such as... Figure 4 As shown, in the schematic refactoring, select the logic reference, that is, select the created terminal wiring system (corresponding node), and then select the CAD drawing. At this time, the schematic from the CAD drawing is imported into the newly created schematic view, as shown. Figure 5 As shown, by combining the equipment attribute information of each electrical device, the reconstructed electrical device in the 3D software is obtained. Specifically, the 3DE (3DExperience) development plugin is used to read the equipment attribute information of the electrical devices in the CAD drawing and reconstruct it under the corresponding node in the logical reference diagram, thus obtaining the electrical device with attribute information in the 3D software.

[0052] The attribute information of multiple terminal blocks on electrical equipment in the 3D software of this invention is automatically created based on the terminal block attribute information obtained in step 1, and automatically created under the corresponding node in the logic reference diagram to obtain a logic structure diagram with terminal block attribute information.

[0053] For example, in 3D software, termination graph reconstruction is selected, such as... Figure 6 As shown, select the established terminal wiring system (corresponding node), and then select the option provided by the manufacturer through CAD drawings, such as... Figure 3The terminal list is shown. The software will automatically read all devices in the terminal list and create them. Additionally, the 3D software will automatically create their terminal numbers based on the terminal list, and will also create terminal signal information, appliance numbers, and other information, such as... Figure 7 As shown.

[0054] Step 3: Based on the terminal wiring command and the automatic routing command for the termination diagram, automatically wire the terminal blocks in the logic structure diagram to obtain the wiring diagram for each terminal block, specifically including:

[0055] Step 3.1: Based on the terminal wiring command and the automatic wiring command of the termination diagram, perform automatic wiring of each terminal in the logic structure diagram to obtain the wiring information of each terminal block; the terminal wiring command includes the electrical equipment information on this side, the electrical equipment information on the other side, and the cable information.

[0056] The information on electrical equipment on both sides includes the name of the electrical equipment, the terminal block number, the serial number of the terminal in the terminal block, and the information inside the terminal, including the signal content and the device number.

[0057] The cable information above includes the cable type and name, and the cable is instantiated.

[0058] This step specifically involves selecting the local and remote electrical equipment based on the terminal signal information and appliance number provided in the 2D diagram of the logic structure diagram, establishing the logic reference node where the cable is located, selecting the cable type and name according to the 2D diagram display, and instantiating the cable; for example... Figure 8 As shown.

[0059] Step 3.1 above specifically includes:

[0060] Step 3.1.1: Obtain the corresponding cable, the terminal of the electrical equipment on this side, and the terminal of the electrical equipment on the opposite side from the terminal wiring command.

[0061] For example, after selecting electrical equipment and cables, the connection information for terminals is selected. Based on the core number corresponding to the cable, and considering the different core numbers corresponding to different cables, the connectors for this side's electrical equipment, the terminals for this side's electrical equipment, the connectors for the opposite side's electrical equipment, and the terminals for the opposite side's electrical equipment are selected, thereby creating the terminal connection information; such as... Figure 8 As shown.

[0062] Step 3.1.2: Using the termination diagram automatic routing command, automatically wire each terminal in the logic structure diagram, so that the corresponding cable connects the corresponding terminal of the electrical equipment on this side and the corresponding terminal of the electrical equipment on the opposite side, and obtains the wiring information of each terminal block.

[0063] For example, select the command for automatic termination diagram connection (i.e., the automatic wiring command for termination diagram) in the 3D software, select the system created at the beginning, and select the newly created electrical equipment according to the table. After selection, the terminal wiring diagram will automatically complete the wiring, as shown. Figure 9 As shown.

[0064] This invention uses the termination diagram automatic routing command to automatically identify electrical equipment ports for conductor connection. Specifically, it selects terminal connection information based on different instantiated cable types and creates terminal links after selection.

[0065] Step 3.2: Determine the wiring diagram for each terminal block based on the wiring information of each terminal block. The wiring information includes the terminal block number, the serial number of the terminal in the terminal block, and the signal content of the terminal.

[0066] For example, after wiring is completed, a termination diagram will be automatically generated. The generated termination diagram will be placed in the termination diagram view created for each device in the terminal block table, such as... Figure 10 As shown; export the generated terminal wiring diagram to a usable file format for easy saving and sharing. The generated terminal wiring diagram can be checked and verified, including verifying the number of terminals, cable paths, etc., to facilitate actual wiring and cabling work by engineers and technicians.

[0067] After automatically wiring each terminal, the present invention can use the termination diagram automatic wiring command to select the nodes in the logic structure diagram and the corresponding electrical equipment within the nodes, thereby automatically generating a standard table of terminal information for the selected electrical equipment with one click, and further generating construction drawings.

[0068] This invention provides a method for automatically drawing terminal wiring diagrams by constructing wiring relationships. This method can solve the problems of tedious manual drawing of wiring diagrams by designers and difficulty in verifying wiring information. It improves the efficiency of designers in manually selecting the connection process of the corresponding terminals on the local and opposite sides of different devices. This method has the advantages of high automation, convenient operation, reduced errors and time saving. It can be widely used in the design and installation of various electrical systems to improve work efficiency and accuracy.

[0069] This invention relates to an automatic terminal wiring drawing method based on 3D software. In the electrical design of hydropower stations, the original termination table is customized into a drawing template for the software. The original single graphic is displayed as terminal blocks and terminals with attributes in the software, which is convenient for computer recognition and use. This computer software can recognize data models and rules, and manually select the connection definitions between devices in the interface. It supports functions such as creating / modifying connections, cable selection, and signal reading. Based on the connection information, the software automatically reads the connection status between devices and inherits the terminal information. The drawing is completed in the view according to the design rules of the hydropower industry. This reduces the repetitive workload of designers in checking connection information, accelerates production efficiency, shortens the design cycle, and thus effectively reduces design costs, generating good economic benefits.

[0070] After automatically wiring the terminal blocks in the logic diagram, this embodiment of the invention further includes:

[0071] Obtain the equipment structure information of the logic structure diagram for the completed automatic terminal block wiring;

[0072] Based on the equipment structure information, the corresponding 3D equipment is arranged to obtain the 3D model corresponding to the logic structure diagram. The equipment structure information includes the name, location, and connection information of each electrical device in the logic structure diagram.

[0073] The three-dimensional model generated in this embodiment of the invention is based on the software-consumable two-dimensional and three-dimensional driving concept. It arranges two-dimensional electrical equipment in detail as three-dimensional equipment, which meets the requirements of three-dimensional collision detection and three-dimensional bidding, and realizes two-dimensional and three-dimensional associated arrangement.

[0074] This invention presents an automatic terminal wiring diagram generation method based on 3D software, providing a fast, efficient, and accurate terminal wiring diagram design and automatic generation solution. This method combines the advantages of 3D software and its developed algorithms, offering electrical system designers and engineers convenient terminal wiring diagram design and generation capabilities. The 3D software incorporates advanced selection and wiring algorithms, automatically selecting suitable terminals, cables, etc., and performing automatic wiring based on user-defined wiring rules and requirements, thus improving design efficiency and accuracy.

[0075] A second aspect of the present invention provides a terminal device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described method.

[0076] This invention automates terminal wiring design with the aid of 3D software, improves design efficiency, reduces the probability of errors when manually selecting terminal block connection equipment, and solves the problem of low efficiency in the manual selection and wiring process.

[0077] In the electrical design of hydropower stations, this invention transforms the original method of describing equipment and systems using natural language such as graphics and documents into a method of using computer-recognizable data models. This allows computers to read the data directly, improving the efficiency and quality of the design work. It also reduces the workload of designers in terms of ports and connections, avoids repetitive work, reduces design errors, shortens the design cycle, and thus effectively reduces design costs, generating good economic benefits.

[0078] This invention provides an efficient and accurate solution for the wiring design of electrical equipment such as hydropower stations by using an automatic terminal wiring drawing method based on 3D software. By utilizing modern 3D modeling and design software, database management systems, and automatic connection algorithms and rules, the wiring design process can be greatly simplified, and the quality and efficiency of the design can be improved. The generated terminal wiring diagrams are clear and can help engineers better understand and manage the electrical wiring relationships of the equipment.

[0079] The application of this invention in hydropower engineering design can generate numerous mature case studies and accumulate a wealth of engineering data solutions, which is beneficial for the inheritance of engineering experience in design units and forms a valuable data asset that can be read and recognized by computers. The automatic terminal wiring drawing method based on 3D software is of great significance in the wiring design of electrical equipment such as hydropower stations, and is expected to continue to develop and improve in the future, providing electrical engineers with better design tools and support.
