[0055] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0056] In an embodiment, at least one embodiment provides a main wiring intelligent generation method. According to the parameters of the main wiring diagram, the main wiring graphic symbols and design parameters are automatically configured, and supplementary selection is supported 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 layout area of the main wiring diagram is first divided, and the corresponding graphic symbols are arranged in the corresponding layout areas according to the design parameters, and the electrical main wiring diagram is automatically generated, forming a structured design scheme for the main wiring diagram, improving the drawing efficiency and quality.

[0057] Please refer to Figure 1 , specifically, the method includes:

[0058] S110: Input the parameters of the main wiring diagram.

[0059] Specifically, the step of inputting the parameters of the main wiring diagram is executed by any one of parameter selection input, scheme reference input, and semantic recognition input. By setting multiple methods for parameter filling, the filling requirements in different situations are met.

[0060] The following explains parameter selection input, scheme reference input, and semantic recognition input respectively:

[0061] The first type is parameter selection input, and the steps are as follows: Provide an enumeration of parameter values for the main wiring design; Receive a selection instruction and / or parameter value to complete the input. Specifically, summarize the parameter values of the graphic symbols required for the historical main wiring diagram to facilitate manual selection. At the same time, parameter values can be manually input, where 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, update the enumeration item of the corresponding graphic symbol to facilitate selection next time.

[0062] The second type is scheme reference input, and the steps are as follows: Select a design scheme from the general design; Automatically input according to the parameter values in the main wiring data of the selected design scheme. Specifically, store the main wiring data of the general design scheme of the substation project. When inputting the parameters of the main wiring diagram, directly select the required general design scheme, and then complete the input according to the main wiring data of the selected design scheme.

[0063] The third type is semantic recognition input, and the steps are as follows: Input the feasibility study report; Perform semantic recognition on the feasibility study report to obtain parameter values; Automatically input according to the obtained parameter values. Specifically, perform semantic recognition on the feasibility study report of the substation project, capture preset keywords from the text paragraphs to complete the acquisition of parameter values, and automatically input the parameter values. Among them, some documents of the feasibility study report are as Figure 2 shown.

[0064] Through the above three methods of inputting the parameters of the main wiring diagram, a structured data form for the main wiring design is generated, which improves the efficiency of scheme analysis and data formation.

[0065] S120: Obtain the corresponding main wiring graphic symbols and design parameters according to the parameters of the main wiring diagram.

[0066] Specifically, step S120 includes the following steps:

[0067] S121: Input the system scheme data into the pre-established standard graphic symbol library and design parameter library for matching.

[0068] It should be noted that the matching process is performed by keyword search.

[0069] Among them, the establishment steps of the standard graphic symbol library and the design parameter library include:

[0070] S210: Scan the drawings of the historical main wiring diagram.

[0071] Specifically, since the main wiring diagrams used in each phase of the substation construction are not drawn by the same electrical engineer, after each construction is completed, the drawings will be stored. 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 main wiring diagrams of previous periods for subsequent use in building the library.

[0072] In standard high-voltage electrical design, components with different voltages need to be placed in different positions for circuit design of different voltage levels and different substation nodes.

[0073] Generally speaking, primary power transformation 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 safety standards of substation design. The voltage on the high-voltage side is high, and the phase-to-phase voltage is the highest. The equipment to be placed requires the highest withstand voltage level. If equipment that does not meet the corresponding withstand voltage standard is placed in the wrong position, it will cause damage to the equipment. Therefore, when laying out high-voltage equipment, it is often necessary to construct according to the paper drawings. When using electrified equipment, the electrified equipment will be punctured or malfunction, resulting in the electrified equipment being unable to work properly. Generally, relevant paper drawings will be laid out near the equipment for easy maintenance.

[0074] The existing main wiring diagrams of the substation can be scanned. For paper documents, scan the corresponding paper documents to generate electronic drawings. For those without paper documents, generate the corresponding scanned format from the electronic documents and then generate electronic drawings. Input them into the server, and the server will perform corresponding cutting processing on the complete electronic drawings, dividing them into the corresponding high-voltage area, medium-voltage area, and low-voltage area.

[0075] First, according to the withstand voltage value of the equipment, distinguish the equipment in the high-voltage area, the equipment in the medium-voltage area, and the equipment in the low-voltage area. The specific voltage changes with the input of the drawing. The specific operation steps are to identify the area with the highest voltage on the electronic drawing, then identify the area with the lowest voltage on the electronic drawing, and then divide the equipment connected to the highest voltage area into high-voltage area equipment, divide the equipment connected to the lowest voltage area into low-voltage area equipment, and the remaining equipment into medium-voltage area equipment. For the equipment in the medium-voltage area that is difficult to divide, on the one hand, the server needs to mark the equipment in doubt, and on the other hand, after marking the area of this part of the equipment in doubt, pack the electronic drawing and send it to the doubtful drawing. Finally, the doubtful part of the drawing will be corrected manually to obtain the correct high-voltage area, medium-voltage area, and low-voltage area. When encountering such drawings or related equipment subsequently, give priority to using the results of manual judgment for comparison. If the comparison error is within 80%, use this result. If the comparison result is lower than 80%, the above steps need to be repeated, and the new forms of the high-voltage area, medium-voltage area, and low-voltage area will be archived and saved in the cloud server.

[0076] When distinguishing the medium - voltage area, the server generally processes it in this way. There are some devices in the circuit for undertaking different voltage parts, such as transformers. This kind of electrical device has both a high - voltage area and a low - voltage area. The existence of such devices is to transform high voltage into low voltage or transform low voltage into high voltage. It is a dividing point in the circuit. We can analyze whether the function of the transformer is to transform high voltage into low voltage or from low voltage to high voltage from the withstand voltage values of the devices connected to both ends of the transformer. Due to the different voltage values of the devices connected to both ends of the electrical device, the two ends of the transformer can be directly or indirectly divided into different voltage - level areas. The server distinguishes different voltage areas along the voltage - transformation direction of the transformer according to the preset program.

[0077] After completing the voltage distinction, the electronic drawing can be divided into different voltage parts, and then the electronic drawing can be simplified into the layout structure of the circuit. Different electronic drawings can be divided into different layout structures, and then the data layout can be supplemented.

[0078] 35 110 S220: Perform graphic recognition on the scanned historical main wiring diagram to obtain graphic symbols and the number of wiring connections.

[0079] Specifically, when receiving the scanned drawing of the historical main wiring diagram, identify the graphic symbols according to the relevant standards of graphic symbols in the power industry, and obtain the graphic symbols and the corresponding number of wiring connections contained in each historical main wiring diagram.

[0080] S230: Based on the obtained graphic symbols and the number of wiring connections corresponding to the graphic symbols, judge whether all the historical main wiring diagrams are blurred.

[0081] Specifically, because the drawings have been stored for a long time, there may be situations such as blurred drawings and missing lines. To handle this situation, classify the same graphic symbols in all historical main wiring diagrams, compare and divide the number of wiring connections of the same graphic symbols, and extract abnormal data.

[0082] Among them, abnormal data refers to classifying and dividing the number of wiring connections of the same graphic symbols. If the number of classified categories is greater than one, mark the main wiring diagram corresponding to the graphic symbols in the category with the least number as abnormal data, that is, indicating that the drawing of this historical main wiring diagram is blurred.

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

[0084] Such as Figure 8As shown, specifically, select the graphic symbols in the fuzzy historical main wiring diagram and compare them with the same graphic symbols in the remaining historical main wiring diagrams. According to the layout form of the fuzzy historical main wiring diagram and the preset layout form, judge all the possible connections of the graphic symbols missing lines, sort them according to the number of occurrences, manually correct the sorting results, receive the instruction of manual selection, and complete the missing lines in the fuzzy historical main wiring diagram, so as to obtain the complete historical main wiring diagram and restore the on-site electrical main wiring diagram.

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

[0086] Specifically, remove the connections between each graphic symbol in each historical main wiring diagram, mark the point information of the graphic symbols of the wiring, complete the acquisition of the graphic symbols, and extract the corresponding design parameters to complete the extraction.

[0087] S260: After associating the obtained graphic symbols and the corresponding design parameters, store them to complete the establishment of the marked graphic symbol library and the design parameter library.

[0088] The graphic symbol library is established according to the historical design scheme of the substation project and the relevant standards of the graphic symbols in the power industry. It has professionalism, the connection point information of the graphic symbols, strong standardization, good versatility, and a wide range of applications; while the design parameter library is established according to the parameter table in the general equipment of the power industry, and the data is complete, comprehensive, and standard.

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

[0090] S122: Obtain the graphic symbols and design parameters according to the matching results.

[0091] Specifically, first select the corresponding graphic symbols according to the parameter values, and then obtain the design parameters associated with the corresponding graphic symbols, so as to select the graphic symbols and design parameters required for the system scheme data. As Figure 3 shown, the style of a certain graphic symbol and the corresponding design parameters are shown.

[0092] S130: Generate the main wiring diagram according to the obtained graphic symbols and design parameters of the main wiring.

[0093] In this embodiment, step S130 includes the following steps:

[0094] S131: Divide the layout area of the main wiring diagram.

[0095] Specifically, in step S131, determine the voltage level according to the system scheme data; obtain the number of arrangement areas according to the voltage level; obtain the adapted layout type from the preset main wiring layout types according to the number of areas.

[0096] Among them, the types of the preset main wiring layout types are as Figure 4 shown.

[0097] S132: Arrange the corresponding graphic symbols in the corresponding arrangement areas according to the design parameters.

[0098] Specifically, step S132, that is, construct the graphic of the wiring form of the distribution device; sort out the placement order of the graphic symbols in each arrangement area.

[0099] Specifically, the wiring form graphic is a single busbar sectionalized wiring, as Figure 5 shown.

[0100] Sort out the placement order of the graphic symbols in each arrangement area. According to the Figure 5 wiring form graphic, from right to left, the incoming line interval is placed in the first gear of the I-section busbar; the main transformer incoming line interval is placed in the second gear of the I-section busbar (after the incoming line interval is arranged on this section of the busbar); the busbar equipment interval is placed in the third gear of the I-section busbar; the sectionalizing interval is placed in the fourth gear of the I-section busbar.

[0101] S133: Automatically generate the electrical main wiring diagram.

[0102] Specifically, step S133, that is, complete the automatic wiring according to the point position information of the graphic symbols and the drawing frame range of each arrangement area, and automatically generate the electrical main wiring diagram.

[0103] For example, as Figure 6 shown, an electrical main wiring diagram after automatic wiring is provided.

[0104] As Figure 7 shown, at least one embodiment also provides a main wiring intelligent generation device.

[0105] The main wiring intelligent generation device includes the following modules: a filling module, an obtaining module, and an automatic generation module.

[0106] The filling module is suitable for inputting the parameters of the input main wiring diagram. Specifically, the step of inputting the parameters of the input main wiring diagram is executed by any one of parameter selection input, scheme reference input, and semantic recognition input. By setting multiple methods for parameter filling, the filling requirements in different situations are met. And it is suitable for executing the above-mentioned step S110.

[0108] As Figure 8 shown, among which, the acquisition module has a standard symbol library and a design parameter library built in, and the establishment process is as follows:

[0109] S210: Scan the drawings of the historical main wiring diagram.

[0110] Specifically, since the main wiring diagrams used in each phase of the construction of the substation are not drawn by the same electrical engineer, after each construction is completed, the drawings will be stored. When establishing the standard symbol library and the design parameter library, in order to ensure the integrity of the data, it is necessary to scan the drawings of the historical main wiring diagrams in the past for subsequent use in building the library.

[0111] S220: Perform graphic recognition on the scanned historical main wiring diagram to obtain symbols and the number of wirings.

[0112] Specifically, when receiving the scanned drawings of the historical main wiring diagram, perform symbol recognition according to the relevant standards of graphic symbols in the power industry to obtain the symbols contained in each historical main wiring diagram and the corresponding number of wirings.

[0113] S230: Judge whether all the historical main wiring diagrams are blurred based on the obtained symbols and the number of wirings corresponding to the symbols.

[0114] Specifically, since the drawings have been stored for a long time, there may be situations where the drawings are blurred and the lines are missing. In order to handle this situation, classify the same symbols in all historical main wiring diagrams, compare and divide the number of wirings of the same symbols, and extract abnormal data.

[0115] Among them, abnormal data refers to classifying and dividing the number of wirings of the same symbols. If the number of classified categories is greater than one, mark the main wiring diagram corresponding to the symbol with the smallest number of the category as abnormal data, that is, indicating that the drawing of this historical main wiring diagram is blurred.

[0116] S240: Complete the blurred historical main wiring diagram to obtain a complete historical main wiring diagram.

[0117] As Figure 8As shown, specifically, select the graphic symbols in the fuzzy historical main wiring diagram and compare them with the same graphic symbols in the remaining historical main wiring diagrams. According to the layout form of the fuzzy historical main wiring diagram and the preset layout form, judge all the possibilities that the graphic symbols missing lines can be connected, sort them according to the number of occurrences, correct the sorting results manually, receive the instruction of manual selection, and complete the missing lines in the fuzzy historical main wiring diagram, so as to obtain the complete historical main wiring diagram and restore the on-site electrical main wiring diagram.

[0118] S250: Remove the lines from the complete historical main wiring diagram to obtain the graphic symbols and the corresponding design parameters.

[0119] Specifically, remove the connections between each graphic symbol in each historical main wiring diagram, mark the point position information of the wired graphic symbols, complete the acquisition of the graphic symbols, and extract the corresponding design parameters accordingly to complete the extraction.

[0120] S260: After associating the obtained graphic symbols and the corresponding design parameters, store them to complete the establishment of the marked graphic symbol library and the design parameter library.

[0121] The graphic symbol library is established based on the historical design scheme of the substation project and the relevant standards of the graphic symbols in the power industry. It has professionalism, graphic symbol connection point position information, strong standardization, good versatility, and a wide range of applications; while the design parameter library is established based on the parameter table in the general equipment of the power industry, with complete, comprehensive, and standard data.

[0122] At the same time, the matching of graphic symbols and design parameters supports default configuration and supplementary selection. New graphic symbols and the corresponding design parameters can be stored manually, with high expression efficiency.

[0124] At least one embodiment also provides a computer-readable storage medium, in which at least one instruction is stored, and when the instruction is executed by a processor, the above-mentioned intelligent main wiring generation method is implemented.

[0125] The intelligent main wiring 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, meeting various expression needs of the electrical main wiring diagram, improving the standardization degree and design quality of the electrical main wiring diagram. When automatically generating the main wiring diagram, first divide the layout area of the main wiring diagram, arrange the corresponding graphic 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 the drawing efficiency and quality.
