[0002] Overhead lines are a crucial component of power distribution networks. Erected above the ground, they are transmission lines that use insulators to anchor conductors to towers and poles to transmit electrical energy. The main components of an overhead transmission line include: conductors, lightning protection wires, hardware, insulators, towers, guy wires and foundations, and grounding devices. Overhead line design drawings are of significant reference value for the actual construction of power distribution networks.

[0067] Reference Figure 2 , Figure 2 FIG. 1 is a flow diagram of an overhead line design graph automatic drawing method based on a power grid graph database according to an embodiment of the present application; the method is applied to Figure 1The overhead line design drawing automatic drawing device and the overhead line design drawing automatic drawing method include but are not limited to steps S210 to S260.

[0068] Step S210: According to the obtained engineering information, survey data and drawing information, automatic drawing processing is performed to obtain a first path diagram and path diagram information displayed on the first path diagram.

[0069] In this step, after obtaining the engineering information, survey data and drawing information input by the engineering personnel in advance, automatic drawing is performed to obtain the first path diagram displaying the path diagram information. The engineering personnel can intuitively obtain the path diagram information through the first path diagram, which facilitates preliminary review and modification of the design drawing.

[0070] According to some embodiments of the present application, the path diagram information includes stake coordinate information, stake name information, angle information and distance information, wherein the angle information is used to represent the angle value between the two intersecting path segments, and the distance information is used to represent the straight-line distance between two stakes.

[0071] Step S220: According to the preset tension segment attribute information, the tension segment attribute setting processing is performed on the first path diagram to obtain a second path diagram.

[0072] In this step, after obtaining the preset tension segment attribute information, the engineering road segments between the path nodes in the first path diagram are automatically set with tension segment attributes to obtain the second path diagram. The construction personnel or auditors can check the tension segment attribute information through the second path diagram, which improves the automatic drawing efficiency and is beneficial to the actual engineering construction.

[0073] According to some embodiments of the present application, the preset tension segment attribute information includes meteorological zone information, tension segment voltage grade, conductor type, loop number, laying method and conductor safety factor.

[0074] It can be understood that one or more engineering road segments can be selected in the first path diagram, and the selected one or more engineering road segments are set with tension segment attributes according to the preset tension segment attribute information, so that these engineering road segments have the same parameter information, batch setting of tension segment attribute parameters is realized, and the efficiency of automatic drawing is improved.

[0075] Step S230: According to the preset tension segment attribute information, matching processing is performed in the power grid graphic database to determine the matched device graph element.

[0076] In this step, the preset tension segment attribute information is used as a reference standard to automatically search for a device graph element matching the reference standard in the power grid graphic database. The device graph element is automatically matched and found to facilitate the next drawing process, and the drawing efficiency is further improved.

[0077] It should be noted that the power grid graphic database is formed based on a Common Information Model (CIM) of a power system, and the power grid graphic database includes a plurality of device graph elements, a graph element attribute table, and a graph element electrical attribute table. Information such as a graph element identifier and a graph element type can be obtained from the graph element attribute table. Based on this, matching processing can be performed in the power grid graphic database to determine a matched device graph element.

[0078] Specifically, the device graph element is a tower. That is, this step can automatically match a tower type in the power grid graphic database according to the preset tension section attribute information.

[0079] Step S240: Obtain tension section pile site information from path graph information.

[0080] In this step, pile site coordinate information and pile site name information of a tower that needs to be drawn can be determined from the path graph information, to provide reference information for drawing a third path graph. The tension section pile site information includes the pile site coordinate information and the pile site name information.

[0081] Step S250: Automatically arrange a device graph element in the second path graph according to the tension section pile site information, to obtain a third path graph.

[0082] In this step, after obtaining the tension section pile site information, the pile site name information of a path node in which a device graph element needs to be inserted, and corresponding pile site coordinate information can be known. The device graph element is drawn on a single path node according to the pile site coordinate information, or the device graph element is automatically arranged in multiple path nodes in sequence according to the pile site coordinate information, to obtain the third path graph, reduce the workload of an engineer, and improve the automatic drawing efficiency.

[0083] Specifically, the device graph element is a tower, and automatic tower arrangement is implemented according to the tension section pile site information.

[0084] Step S260: Automatically set device attributes in bulk for a device graph element in the third path graph according to a preset graph element identifier and corresponding device attribute information, to obtain an overhead line design graph.

[0085] In this step, after obtaining the preset graph element identifier and the corresponding device attribute information, device attributes are automatically set in bulk for a device graph element having the graph element identifier, to obtain the overhead line design graph, reduce the workload of an engineer, and improve the drawing efficiency.

[0086] According to some embodiments of the present application, the device icons in the third path diagram are automatically set with device attributes in batches according to the preset icon identification number and the corresponding device attribute information, and an overhead line design diagram is obtained, comprising: obtaining the preset icon identification number and the corresponding device attribute information; selecting at least one first target device icon from the device icons in the third path diagram according to the icon identification number; and setting the attributes of the first target device icon according to the device attribute information to obtain the overhead line design diagram. After the first target device icon is selected based on the icon identification number, the attributes are set uniformly, which has high automation and improves the drawing efficiency.

[0087] The embodiment of the present application can first perform automatic drawing processing according to the obtained engineering information, survey data and drawing information to obtain a first path diagram and path diagram information displayed on the first path diagram, then perform tension segment attribute setting processing on the first path diagram according to preset tension segment attribute information to obtain a second path diagram, then perform matching processing in the power grid graphic database according to the preset tension segment attribute information to determine the matched device icons, then obtain the tension segment stake point information from the path diagram information, then automatically arrange the device icons in the second path diagram according to the tension segment stake point information to obtain a third path diagram, and finally automatically set the device attributes of the device icons in the third path diagram in batches according to the preset icon identification number and the corresponding device attribute information to obtain an overhead line design diagram. Therefore, according to the scheme provided by the embodiment of the present application, the overhead line design diagram can be automatically drawn in the distribution network design planning stage, the workload of the engineering personnel is reduced, and the drawing efficiency of the overhead line design diagram is improved.

[0088] Reference Figure 3 , Figure 3 is an embodiment of the present application Figure 2 The specific method flowchart of step S210 is shown in the figure. Step S210 includes but is not limited to steps S310 to S340.

[0089] Step S310: Obtain preset path starting point information, preset path intermediate node information and preset path termination point information according to drawing information.

[0090] In this step, after obtaining the drawing information, the preset path starting point information, the preset path intermediate node information and the preset path termination point information are obtained through the drawing information. The drawing information can be default initial information or drawing information preliminarily set by a designer, so as to draw the first line as a basis.

[0091] Step S320: Perform automatic connection processing according to the preset path starting point information, the preset path intermediate node information and the preset path termination point information to obtain a first line.

[0092] In this step, the first line obtained after automatic connection processing can serve as the basis for subsequent drawing adjustment.

[0093] Step S330: adjusting the first line according to the engineering information and the survey data to obtain a second line.

[0094] In this step, the survey data includes real coordinates of path nodes, slope information, etc., and the engineering information includes engineering design standards, etc. The line adjustment processing of the first line based on the engineering information and the survey data includes but is not limited to adjusting the line angle, stretching the specific length between the previous path node, and adjusting the angle of the corner, etc. The second line that is more in line with the actual construction situation can be obtained after the line adjustment processing.

[0095] Step S340: performing naming and labeling processing on the second line to obtain a first path map and path map information.

[0096] In this step, the path labeling distance information in the second line, the pile site coordinate information, the pile site name information, and the angle information are labeled on the path nodes (i.e., pile site points) according to the survey data. The pile site name information can be a digital number. After the naming and labeling processing is completed, the first path map is obtained, and the path map information is displayed on the first path map.

[0097] Through steps S310 to S340, the first path map is automatically drawn based on real survey data and engineering information, reducing the amount of manual work and improving the drawing efficiency.

[0098] Reference Figure 4 , Figure 4 is a flowchart of an overhead line design map optimization method provided by an embodiment of the present application. According to some embodiments of the present application, after obtaining the overhead line design map, the overhead line design map automatic drawing method further includes but is not limited to steps S410 to S450.

[0099] Step S410: obtaining field survey pictures and ground object information according to the survey data.

[0100] Step S420: obtaining a background image after format modification and image processing on the field survey pictures.

[0101] Step S430: determining ground object types and ground object coordinate information according to the ground object information.

[0102] Step S440: selecting ground object models from a power grid graphics database according to the ground object types.

[0103] Step S450: importing the background image into the overhead line design drawing, and automatically drawing the ground object model in the overhead line design drawing according to the ground object coordinate information, to obtain an optimized overhead line design drawing.

[0104] By implementing steps S410 to S450, the field survey picture and the ground object information can be obtained from the survey data, the background image and the ground object model can be obtained after processing the field survey picture and the ground object information, and then the background image is imported into the overhead line design drawing and the ground object model is drawn, so that the overhead line design drawing is optimized. Based on the real survey data, the overhead line design drawing is optimized, and the overhead line design drawing is enriched, so as to provide more reliable reference design drawing for engineering personnel.

[0105] It should be noted that the formats and specifications of different images collected in actual survey may not be consistent, so the format of the field survey picture needs to be modified to a format supported by the processor, specifically, the supported format is DXF format; the image processing includes scaling, cropping and other processing, and the background image with appropriate specifications is obtained after image processing; after importing the background image, the content of the overhead line design drawing is enriched, so that the overhead line design drawing has higher referenceability.

[0106] Reference Figure 5 , Figure 5 is a flowchart of the modified and updated overhead line design drawing provided by an embodiment of the present application. According to some embodiments of the present application, after obtaining the overhead line design drawing, the overhead line design drawing automatic drawing method further includes but is not limited to steps S510 to S540.

[0107] Step S510: selecting at least one to-be-processed device graph element in the overhead line design drawing.

[0108] In this step, at least one to-be-processed device graph element can be selected in the overhead line design drawing according to the input screening information, and the screening information can be a graph element identification number, an attribute name, coordinate information, etc. Alternatively, the to-be-processed device graph element can be manually selected by engineering personnel.

[0109] Step S520: screening in the power grid graphic database according to the preset screening information to obtain a device graph element recommendation list, the device graph element recommendation list including a plurality of candidate device graph elements sorted in descending order of relevance.

[0110] In this step, according to the preset screening information, a plurality of candidate device graph elements with high relevance to the preset screening information are screened out from the power grid graph database, and the plurality of candidate device graph elements are sorted in descending order of relevance to obtain a device graph element recommendation list. The preset screening information includes attribute information, device model and other information. The more the candidate device graph elements meet the screening conditions in the preset screening information, the higher the relevance is; otherwise, the lower the relevance is.

[0111] Step S530: determining a second target device graph element from the plurality of candidate device graph elements.

[0112] In this step, the candidate device graph element with the highest relevance in the device graph element recommendation list can be automatically selected as the second target device graph element. The second target device graph element can also be determined through the selection operation of an engineer.

[0113] Step S540: replacing the to-be-processed device graph element according to the second target device graph element to obtain an updated overhead line design graph.

[0114] In this step, after the second target device graph element is determined, the to-be-processed device graph element is replaced by the second target device graph element to realize batch modification and obtain an updated overhead line design graph.

[0115] Through steps S510 to S540, when the overhead line changes, a plurality of graph elements can be selected for batch modification, thereby reducing the artificial workload and improving the drawing efficiency.
