[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] Embodiments, at least one embodiment provides a main wiring intelligent generation method, which automatically configures the main wiring graphic symbols and design parameters according to the parameters of the main wiring diagram, and supports supplementary selection to meet various expression needs of the electrical main wiring diagram, improve the standardization degree and design quality of the electrical main wiring diagram, and when the main wiring diagram is automatically generated, first divide the main wiring diagram layout area, arrange the corresponding symbols in the corresponding layout area according to the design parameters, and automatically generate the electrical main wiring diagram, forming a structured design scheme for the main wiring diagram, improving drawing efficiency and quality.

[0030] See also Figure 1 Specifically, the method comprises: S110: Input the parameters of the main wiring diagram.

[0031] Specifically, the step of inputting the parameters of the main wiring diagram is performed by any one of the three methods: parameter selection input, scheme reference input, and semantic recognition input. By setting a variety of methods for parameter reporting, reporting requirements in different situations can be met.

[0032] The following explains parameter selection input, solution reference input, and semantic recognition input respectively: The first type is parameter selection input, which has the following steps: providing an enumeration item of the parameter value of the main wiring design; receiving a selection instruction and / or a parameter value, and completing the input. Specifically, the parameter values ​​of the icons required for the historical main wiring diagram are summarized to facilitate manual selection. At the same time, the parameter values ​​can be manually input, wherein the manually input parameter values ​​can be existing parameter values ​​or new parameter values ​​proposed according to new design requirements. Each time a parameter value is received, the enumeration item of the corresponding icon is updated to facilitate the next selection.

[0033] The second method is scheme reference input, which has the following steps: select a design scheme from the general design; and automatically input the parameter values ​​in the main wiring data of the selected design scheme. Specifically, the main wiring data of the general design scheme of the substation project is stored, and when inputting the parameters of the main wiring diagram, the required general design scheme is directly selected, and then the input is completed according to the main wiring data of the selected design scheme.

[0034] The third type is semantic recognition input, which has the following steps: input the feasibility study report; perform semantic recognition on the feasibility study report to obtain parameter values; and automatically input the parameter values ​​based on the obtained parameter values. Specifically, the feasibility study report of the substation project is semantically recognized, preset keywords are captured from the text paragraphs, the parameter values ​​are obtained, and the parameter values ​​are automatically input. Figure 2 shown.

[0035] By using the above three methods of inputting parameters of the main wiring diagram, a structured data form for the main wiring design is generated, thereby improving the efficiency of scheme analysis and data formation.

[0036] S120: Obtaining corresponding main wiring diagram symbols and design parameters according to the parameters of the main wiring diagram.

[0037] Specifically, step S120 includes the following steps: S121: Input the system solution data into the pre-established standard symbol library and design parameter library for matching.

[0038] It should be noted that the matching process uses keyword search to perform matching.

[0039] The steps of establishing the standard symbol library and the design parameter library include: S210: Scan the historical main wiring diagram drawing.

[0040] Specifically, since the main wiring diagram used in each phase of substation construction is not drawn by the same electrical engineer, the drawings will be stored after each construction is completed. When establishing the standard symbol library and design parameter library, in order to ensure the integrity of the data, it is necessary to scan the drawings of the main wiring diagrams of the past periods for subsequent library construction.

[0041] In standard high-voltage electrical design, components of different voltages need to be placed in different locations to design circuits for different voltages and different substation nodes.

[0042] Generally speaking, a primary substation is divided into a high-voltage area, a medium-voltage area, and a low-voltage area. The distribution relationship between each part needs to comply with the substation design safety standards. The voltage on the high-voltage side is high, the phase-to-phase voltage is the highest, and the required equipment needs to have the highest withstand voltage level. If the equipment that does not meet the corresponding withstand voltage standards is placed in a misplaced position, the equipment will be damaged. Therefore, when laying out high-voltage equipment, it is often necessary to follow paper drawings for construction. When electrified equipment is used, the electrified equipment will be broken down or equipment failure will occur, causing the electrified equipment to fail to work properly. Generally, relevant paper drawings will be laid out near the equipment for easy maintenance.

[0043] The existing substation main wiring drawings can be scanned. If there are paper documents, the corresponding paper documents can be scanned to generate electronic drawings. If there are no paper documents, the electronic files can be generated into the corresponding scanning format and then electronic drawings can be input into the server. The server will cut the complete electronic drawings into corresponding high-voltage areas, medium-voltage areas and low-voltage areas.

[0044] First, according to the withstand voltage value of the equipment, distinguish the equipment in the high-voltage zone, the equipment in the medium-voltage zone, and the equipment in the low-voltage zone. The specific voltage changes with the input of the drawing. The specific operation steps are to identify the highest voltage area on the electronic drawing, and then identify the lowest voltage area on the electronic drawing. Then, the equipment connected to the highest voltage area is divided into high-voltage area equipment, the equipment connected to the lowest voltage area is divided into low-voltage area equipment, and the remaining equipment is divided into medium-voltage area equipment. For equipment in the medium-voltage zone that is difficult to divide, on the one hand, the server needs to mark the doubtful equipment, and on the other hand, after marking the doubtful equipment area, the electronic drawing needs to be packaged and sent to the doubtful drawing. Finally, the doubtful part of the drawing is corrected manually to obtain the correct high-voltage area, medium-voltage area and low-voltage area. When encountering such drawings or related equipment in the future, the result area of ​​manual judgment is preferred. If the comparison error is 80%, the result is adopted. If the comparison result is less than 80%, the above steps need to be repeated, and the new high-voltage area, medium-voltage area and low-voltage area are archived and saved to the cloud server.

[0045] When distinguishing the medium voltage area, the server generally handles it this way. There are some devices in the circuit for taking on different voltage parts, such as transformers. This electrical equipment has both high-voltage and low-voltage areas. The existence of such equipment is to convert high voltage to low voltage or low voltage to high voltage. It is a dividing point in the circuit. The withstand voltage value of the equipment connected at both ends of the transformer can be used to analyze whether the function of the transformer is from high voltage to low voltage or from low voltage to high voltage. Due to the different voltage values ​​of the connecting equipment at both ends of the electrical equipment, the two ends of the transformer can be directly or indirectly divided into different voltage level areas. The server distinguishes different voltages along the voltage conversion direction of the transformer according to the preset program.

[0046] After completing the voltage differentiation, the electronic drawings can be divided into different voltage parts, and then the electronic drawings can be simplified into the layout structure of the circuit. Different electronic drawings can be divided into different layout structures, thereby supplementing the data bureau.

[0047] 35 110 S220: Perform graphic recognition on the scanned historical main wiring diagram to obtain the graphic symbols and wiring quantity.

[0048] Specifically, when a scanned drawing of a historical main wiring diagram is received, the graphic symbols are identified according to relevant standards for graphic symbols in the electric power industry to obtain the graphic symbols contained in each historical main wiring diagram and the corresponding number of wiring connections.

[0049] S230: judging whether all historical main wiring diagrams are ambiguous based on the acquired icons and the number of wirings corresponding to the icons.

[0050] Specifically, since the drawings are stored for a long time, they may be blurred or have missing lines. In order to deal with this situation, the same symbols in all historical main wiring diagrams are classified, and the number of connections of the same symbols are compared and divided to extract abnormal data.

[0051] The abnormal data refers to the classification and division of the number of wirings of the same icon. If the number of the classified categories is greater than one, the main wiring diagram corresponding to the icon of the category with the least number is marked as abnormal data, that is, indicating that the drawing of the historical main wiring diagram is blurred.

[0052] S240: Complete the ambiguous historical main wiring diagram to obtain a complete historical main wiring diagram.

[0053] like Figure 8 As shown, specifically, the icons in the fuzzy historical main wiring diagram are selected and compared with the same icons in the rest of the historical main wiring diagrams. According to the layout form of the fuzzy historical main line diagram and the preset layout form, all possibilities for connecting the icons of the missing lines are determined and sorted according to the number of occurrences. The sorting results are manually corrected, and the instructions for manual selection are received to complete the missing lines in the fuzzy historical main wiring diagram, thereby obtaining a complete historical main wiring diagram and restoring the on-site electrical main wiring diagram.

[0054] S250: Remove the wires from the complete historical main wiring diagram to obtain the graphic symbols and corresponding design parameters.

[0055] Specifically, the connection between each symbol in each historical main wiring diagram is removed, and the symbol point information of the wiring is marked to complete the acquisition of the symbol, and then the corresponding design parameters are extracted to complete the extraction.

[0056] S260: Associating the acquired icons with the corresponding design parameters and storing them, thus completing the establishment of the annotation icon library and the design parameter library.

[0057] The graphic symbol library is established based on the historical design plans of substation projects and relevant standards for graphic symbols in the power industry. It has professionalism and graphic connection point information, strong standardization, good versatility and a wide range of applications. The design parameter library is established based on the parameter tables of common equipment in the power industry, and the data is complete, comprehensive and standard.

[0058] At the same time, the matching of icons and design parameters supports default configuration and supplementary selection. New icons and corresponding design parameters can be stored manually, which has high expression efficiency.

[0059] S122: Obtaining icons and design parameters according to the matching results.

[0060] Specifically, firstly, the corresponding icon is selected according to the parameter value, and then the design parameters associated with the corresponding icon are obtained, so as to select the icon and design parameters required by the system solution data. Figure 3 As shown, the style of a certain icon and the corresponding design parameters are shown.

[0061] S130: Generate a main wiring diagram according to the acquired main wiring symbols and design parameters.

[0062] In this embodiment, step S130 includes the following steps: S131: Divide the main wiring diagram layout area.

[0063] Specifically, step S131, that is, determining the voltage level according to the system solution data; obtaining the number of layout areas according to the voltage level; and obtaining an adapted layout type from the preset main wiring layout types according to the number of areas.

[0064] Among them, the types of preset main wiring layout types are as follows Figure 4 shown.

[0065] S132: Arranging corresponding icons in corresponding layout areas according to design parameters.

[0066] Specifically, step S132 is to construct a wiring diagram of the power distribution device; and sort out the placement order of the icons in each layout area.

[0067] Specifically, the wiring diagram is a single busbar segmented wiring, such as Figure 5 shown.

[0068] Sort out the order of the icons in each layout area, according to Figure 5 In the wiring diagram, from right to left, the incoming line interval is placed at the 1st position of bus section I; the main transformer incoming line interval is placed at the 2nd position of bus section I (after the incoming line interval is arranged on the bus section); the busbar interval is placed at the 3rd position of bus section I; and the segmented interval is placed at the 4th position of bus section I.

[0069] S133: Automatically generate the main electrical wiring diagram.

[0070] Specifically, step S133, that is, completing automatic wiring according to the point information of the icon and the frame range of each layout area, and automatically generating the electrical main wiring diagram.

[0071] For example, Figure 6 As shown, a main electrical wiring diagram is provided after automatic wiring is completed.

[0072] like Figure 7 As shown, at least one embodiment also provides a main wiring intelligent generation device.

[0073] The main wiring intelligent generation device includes the following modules: a reporting module, an acquisition module and an automatic generation module.

[0074] The reporting module is suitable for inputting the parameters of the main wiring diagram. Specifically, the step of inputting the parameters of the main wiring diagram is performed by any one of the three methods of parameter selection input, scheme reference input, and semantic recognition input. By setting a variety of methods for parameter reporting, the reporting requirements in different situations can be met. And it is suitable for executing the above-mentioned step S110.

[0075] The acquisition module is adapted to acquire the corresponding main wiring diagram symbol and design parameters according to the parameters of the main wiring diagram, and is adapted to execute the above-mentioned step S120.

[0076] like Figure 8 As shown, the acquisition module has a built-in standard symbol library and a design parameter library, and the establishment process is as follows: S210: Scan the historical main wiring diagram drawing.

[0077] Specifically, since the main wiring diagram used in each phase of substation construction is not drawn by the same electrical engineer, the drawings will be stored after each construction is completed. When establishing the standard symbol library and design parameter library, in order to ensure the integrity of the data, it is necessary to scan the drawings of the main wiring diagrams of the past periods for subsequent library construction.

[0078] S220: Performing graphic recognition on the scanned historical main wiring diagram to obtain graphic symbols and wiring quantities.

[0079] Specifically, when a scanned drawing of a historical main wiring diagram is received, the graphic symbols are identified according to relevant standards for graphic symbols in the electric power industry to obtain the graphic symbols contained in each historical main wiring diagram and the corresponding number of wiring connections.

[0080] S230: judging whether all historical main wiring diagrams are ambiguous based on the acquired icons and the number of wirings corresponding to the icons.

[0081] Specifically, since the drawings are stored for a long time, they may be blurred or have missing lines. In order to deal with this situation, the same symbols in all historical main wiring diagrams are classified, and the number of connections of the same symbols are compared and divided to extract abnormal data.

[0082] The abnormal data refers to the classification and division of the number of wirings of the same icon. If the number of the classified categories is greater than one, the main wiring diagram corresponding to the icon of the category with the least number is marked as abnormal data, that is, indicating that the drawing of the historical main wiring diagram is blurred.

[0083] S240: Complete the ambiguous historical main wiring diagram to obtain a complete historical main wiring diagram.

[0084] like Figure 8 As shown, specifically, the icons in the fuzzy historical main wiring diagram are selected and compared with the same icons in the rest of the historical main wiring diagrams. According to the layout form of the fuzzy historical main line diagram and the preset layout form, all possibilities for connecting the icons of the missing lines are determined and sorted according to the number of occurrences. The sorting results are manually corrected, and the instructions for manual selection are received to complete the missing lines in the fuzzy historical main wiring diagram, thereby obtaining a complete historical main wiring diagram and restoring the on-site electrical main wiring diagram.

[0085] S250: Remove the wires from the complete historical main wiring diagram to obtain the graphic symbols and corresponding design parameters.

[0086] Specifically, the connection between each symbol in each historical main wiring diagram is removed, and the symbol point information of the wiring is marked to complete the acquisition of the symbol, and then the corresponding design parameters are extracted to complete the extraction.

[0087] S260: Associating the acquired icons with the corresponding design parameters and storing them, thus completing the establishment of the annotation icon library and the design parameter library.

[0088] The graphic symbol library is established based on the historical design plans of substation projects and relevant standards for graphic symbols in the power industry. It has professionalism and graphic connection point information, strong standardization, good versatility and a wide range of applications. The design parameter library is established based on the parameter tables of common equipment in the power industry, and the data is complete, comprehensive and standard.

[0089] At the same time, the matching of icons and design parameters supports default configuration and supplementary selection. New icons and corresponding design parameters can be stored manually, which has high expression efficiency.

[0090] The automatic generation module is adapted to generate a main wiring diagram according to the acquired main wiring symbols and design parameters, and is adapted to execute the above-mentioned step S130.

[0091] At least one embodiment further provides a computer-readable storage medium, wherein the computer-readable storage medium stores at least one instruction, and when the instruction is executed by a processor, the above-mentioned main wiring intelligent generation method is implemented.

[0092] The main wiring intelligent generation method automatically configures the main wiring graphic symbols and design parameters according to the parameters of the main wiring diagram, and supports supplementary selection to meet various expression needs of the electrical main wiring diagram, improve the standardization degree and design quality of the electrical main wiring diagram. When the main wiring diagram is automatically generated, the main wiring diagram layout area is first divided, and the corresponding symbols are arranged in the corresponding layout area according to the design parameters.
