Description

Technical Field

[0001] The invention relates to a method and device for generating a full-path drawing of a secondary circuit, electronic equipment and a storage medium, and belongs to the field of image recognition and computer vision. Background Art

[0002] The work content and working environment of professionals related to the secondary circuit of the substation, in addition to measuring or operating the actual primary and secondary equipment of the substation, is to consult the secondary circuit design drawings. The secondary circuit drawings are a two-dimensional display of the actual secondary circuit of the substation, which plays an important role in the learning of relevant professional and technical personnel and auxiliary analysis during troubleshooting. However, for a long time, the operation and design of the secondary system mainly rely on traditional unstructured drawings such as CAD. The secondary circuit design drawings of the actual substation are complicated and have a large number of components. There are dozens or even hundreds of interval drawings, and there are dozens or even hundreds of secondary circuit components (terminals, relays, contacts, wires, etc.) on each drawing. Therefore, when operators work on site, the workload of consulting the primary and secondary equipment drawings is huge and the efficiency is low. It is not only time-consuming, but also very easy to make mistakes or omissions.

[0003] For the above problem, patent CN104484499A performs substation secondary circuit modeling by parsing CAD files, thereby realizing rapid generation of dynamic simulation images of actual substation secondary circuits. However, this method is only for substation secondary circuit modeling with CAD files, and cannot solve the problem of substation secondary circuit modeling with only paper files.

[0004] Patent CN116702396A realizes the modeling of a single paper drawing by parsing a single drawing file. However, this method ignores the correlation between the secondary circuits of the same substation and fails to consider the connection between multiple drawings during the modeling process.

[0005] In addition, the existing patents CN104484499A and CN116702396A are drawn completely according to the drawing format, and reading the drawings requires certain professional knowledge, that is, the professional requirements are relatively high.

[0006] In summary, the substation secondary circuit modeling method in the prior art has many problems:

[0007] (1) Some existing stations only have paper secondary circuit diagrams, but no CAD electronic diagrams, and lack intelligent tools for modeling based on paper diagrams;

[0008] (2) When working on-site, operators often need to consult multiple related primary and secondary equipment drawings (including design institute drawings, primary manufacturer schematics, and secondary manufacturer schematics) at the same time. This process is time-consuming, labor-intensive, and inefficient. It is impossible to quickly and accurately extract information from multiple drawings and apply it to on-site operations. Summary of the invention

[0009] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for generating a full-path drawing of a secondary circuit, thereby solving the existing problem that modeling cannot be performed based on paper drawings.

[0053] The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0054] Example 1

[0055] The present invention provides a method for generating a secondary circuit full path drawing, such as Figure 1 As shown, the method comprises the following steps:

[0056] Step 1: Create a graphic element library based on the objects included in the secondary circuit paper drawing within the target range.

[0057] Specifically, a general SVG graphic element library is designed according to the paper drawing. For example, each type of object such as terminals, ports, circuit breakers, circuit breakers, relays, etc. needs to design an SVG format graphic element to facilitate flexible application and expansion in the drawing of the secondary full path diagram. Fig. 9 It shows some object schematic diagrams in the design completion drawing and primary and secondary schematic diagrams of the substation.

[0058] Here is an example SVG file of a long closed node:

[0059] <svg width="138" height="26" viewbox="0 0 138 26" fill="none" xmlns="http: / / www.w3.org / 2000 / svg">

[0060] <path d="M98.5 20.5L49 1.5H0" stroke="#CFB8FF" stroke-width="2" / >

[0061] <path d="M91.5 26V1H138" stroke="#CFB8FF" stroke-width="2" / >

[0062] < / svg>

[0063] Step 2: Classify, label and set parent-child relationships for the graphics in the graphics library.

[0064] Specifically, the information describing the parent-child relationship includes: a parent graphic element and a corresponding child graphic element; for example: a graphic element of type terminal belongs to a panel cabinet, a node of type capacitor belongs to equipment, and equipment belongs to a panel cabinet, etc.

[0065] Step 3: Identify each paper image within the target range in turn to obtain the basic information, type, parent-child relationship, and connection relationship between the corresponding graphic elements of the paper image.

[0066] The identification of each paper map within the target range includes:

[0067] Step 31: Use target detection technology to identify objects in the paper image and obtain basic information of the corresponding image elements; wherein the basic information includes: position, size and shape.

[0068] In order to better identify the information in the drawings, the target detection technology uses the improved yolov5 algorithm model for detection, such as Figure 2 As shown, the specific detection process includes: terminal block area detection, device area detection, object text and object type detection and connection line detection.

[0069] It should be noted that, since there are various types of detection rectangles of different sizes in the detection of various element information areas, the improved yolov5 algorithm model refers to improving the head part of the yolov5 algorithm model, adding a detection head and the corresponding size of the detection head on the basis of the original yolov5, so that the head part of the improved yolov5 algorithm model can realize the function of detecting multiple different sizes. The improved yolov5 can adapt to targets of different sizes when checking targets of different sizes, wherein the detection sizes include: 160×160, 80×80, 40×40, 20×20.

[0070] Step 32: Use semantic segmentation technology to identify the object names in the paper image and obtain the types and inclusion relationships of the corresponding graphic elements.

[0071] In order to more accurately identify the content of the text area detected by the yolov5 algorithm model, an attention mechanism layer is added to the CRNN algorithm model. Figure 3As shown in the figure, an attention mechanism layer is added after the recurrent neural network layer, and the attention mechanism is used to perform feature screening on the features extracted by the recurrent neural network, screen useful information, and eliminate noise feature information. Finally, the extracted feature information is passed through the translation layer to output its recognition result.

[0072] Step 33: Use image analysis technology to identify the lines in the paper diagram and obtain the connection relationship between the corresponding graphic elements.

[0073] Specifically, the information describing the connection relationship includes: the connection type, connection direction and connection port between different graphic elements.

[0074] Step 4: Integrate the basic information, type, parent-child relationship and connection relationship between the elements in all secondary circuit paper drawings within the target range to generate a standardized model file.

[0075] Specifically, the information of the recognized image is described in a JSON file, which mainly includes:

[0076] Basic information of each object: Lists the basic properties of each object, such as ID, name, type, and description.

[0077] Object inclusion relationship: describes the sub-object information contained in each object.

[0079] Number of cabinets passed by the entire path: counts the number of cabinets involved in the entire path.

[0080] Number of devices involved in each cabinet: Count the number of devices contained in each cabinet.

[0081] More specifically, the JSON file description includes: root-level fields and data fields.

[0112] Step 5: Based on the standardized model file, draw a full path drawing of the secondary circuit within the target range.

[0113] Example 2

[0114] Based on Example 1, this example provides a specific process of drawing a full path drawing of a secondary circuit within a target range.

[0115] Draw a full-path diagram of the secondary circuit within the target range, including:

[0116] Step 51: Generate screen cabinet layout.

[0117] Specifically, generating the screen cabinet layout includes:

[0118] Step 511: Determine the number of screen cabinets according to the recognition result;

[0119] Step 512: Determine the height of the screen cabinet according to the number of times the connection line passes through the screen cabinet; for example, if the number of times the connection line passes through the screen cabinet is twice, the height of the screen cabinet is 2×30x+20.

[0120] Step 513: Determine the width of the screen cabinet according to the maximum number of nodes that enter the screen cabinet at a single time; for example, if a maximum of 5 nodes pass through the screen cabinet at the same time, the width of the screen cabinet is 5×30x+20.

[0121] Figure 5 An example of a secondary circuit passing through two cabinets is shown: the line passes through the first cabinet twice, and the first time it passes through 5 nodes in the cabinet.

[0122] Step 52: Generate node layout.

[0123] Specifically, the generating node layout includes: arranging the nodes passing through the screen cabinet in a preset arrangement direction in the screen cabinet; Figure 6 As shown, if the same node belonging to the same cabinet is passed through twice, the line is changed in the cabinet and the arrangement direction is adjusted to the opposite direction of the preset arrangement direction.

[0124] Step 53: Connect the nodes with line segments.

[0125] Specifically, the connecting nodes with line segments includes: connecting the nodes according to the connection principle that the first row is arranged in a preset direction and the second row is arranged in the opposite direction of the preset direction; wherein, line segments of different colors are used for connection within the same screen cabinet and between different screen cabinets.

[0126] like Figure 7 As shown, in this embodiment, the first row is from left to right, and the second row is from right to left. The nodes are connected by line segments. The lines within the same screen cabinet are connected with blue line segments, and the lines between different screen cabinets are connected with yellow line segments.

[0127] Step 54: Frame the nodes belonging to the same device.

[0128] Specifically, Figure 8 As shown, the nodes belonging to a certain device are framed with color blocks for easy identification and distinction.
