Description

Technical Field

[0001] This invention relates to the field of electronic digital data processing, and specifically to a secondary system drawing system based on full-loop diagram positioning using graphic codes. Background Technology

[0002] The design of secondary circuits in power systems is a crucial link in ensuring the normal operation of the system's automated control, protection, and monitoring functions. Traditional secondary system drawings are mainly drawn manually, relying on engineers to manually organize a large amount of component information and connection logic. This is not only inefficient but also prone to problems such as missing or incorrect connections, leading to unclear logic and difficulty in positioning during subsequent construction or maintenance. Therefore, a drawing system that can automatically convert drawing code information into circuit diagrams is needed to improve work efficiency.

[0003] The foregoing description of the background art is intended only to facilitate understanding of the invention. This description does not endorse or acknowledge any common general knowledge in the materials mentioned.

[0004] Many secondary drawing systems have been developed. Extensive research and reference have revealed existing systems such as the one disclosed in publication number CN111522537B. These systems generally involve: analyzing the drawing patterns of electrical secondary circuit diagrams and identifying the drawing characteristics of different types of electrical components in the secondary circuit; defining custom function names based on the characteristics of each electrical component in the secondary circuit, and writing corresponding parametric drawing programs for the electrical components based on these custom function names; placing the parametric drawing program file in the installation directory of the drawing software, modifying the internal settings of the drawing software, and loading the parametric drawing program file into the software's startup items; starting the drawing software, inputting the custom drawing function in the command line, calling the parametric drawing program, and achieving parametric drawing to create the electrical secondary circuit diagram. However, this system still requires a significant amount of manual operation for drawing and cannot directly convert diagram information into circuit diagrams, thus its work efficiency needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings by proposing a secondary system drawing system based on full-loop diagram positioning using image codes.

[0006] The present invention adopts the following technical solution:

[0007] A secondary system drawing system based on image code positioning full-loop diagram includes an image code parsing module, a topology generation module, a loop identification drawing module, and a user interaction module;

[0008] The image code parsing module is used to receive image code information and perform parsing processing; the topology generation module generates the topological relationship between components based on the parsing result; the loop identification and drawing module identifies loops based on the topological relationship and draws them; and the user interaction module is used to perform interactive operations and display the final drawing result.

[0009] The image code parsing module includes an image code recognition unit, an information matching unit, and a location positioning unit. The image code recognition unit is used to identify the device type, number, and function identifier to which the image code belongs. The information matching unit is used to map the image code to standard device attributes in the database. The location positioning unit is used to determine the location and logical area to which the device belongs in the image.

[0010] The topology generation module includes a logical relationship construction unit, a connection template calling unit, and a structure verification unit. The logical relationship construction unit establishes the connection logic between devices based on device attributes and graphic code rules. The connection template calling unit is used to quickly construct local connections by referencing commonly used loop connection templates. The structure verification unit is used to monitor structural anomalies such as isolated points and redundant connections in the topology.

[0011] The circuit identification and drawing module includes a circuit classification unit, a path tracking unit, and a graphic generation unit. The circuit classification unit is used to identify types such as control circuits, trip and close circuits, and protection circuits. The path tracking unit is used to trace the closed path of the circuit and confirm the starting and ending components. The graphic generation unit draws equipment symbols and connection lines according to electrical diagram standards.

[0012] The user interaction module includes an input management unit, a drawing interaction unit, and a result output unit. The input management unit is used to support batch import of drawing codes and setting of circuit parameters. The drawing interaction unit is used to edit components and view their attributes. The result output unit is used to export the final drawing into a set file.

[0013] Furthermore, the logical relationship construction unit includes an attribute association processor, a connection path generation processor, and a priority judgment processor. The attribute association processor automatically determines the upstream and downstream components that the device may connect to based on the device's functions. The connection path generation processor generates connection paths based on the logical rules between components. The priority judgment processor is used to determine the key logical path that is prioritized among multiple connection options.

[0014] Furthermore, the connection path generation processor calculates the connection score S between the two elements according to the following formula. ij :

[0015] S ij =α·f(F i F j )+β·d(Pi P j )+γ·r(R i R j );

[0016] Where, f(F) i F j ) represents the upstream and downstream rating between the i-th component and the j-th component, d(P i P j ) represents the spatial distance between the i-th component and the j-th component, r(R) i R j ) represents the loop rule matching degree between the i-th element and the j-th element, where α, β, and γ are three weighting coefficients;

[0017] When the connection score is greater than the minimum connection threshold, it means that the two components can be connected.

[0018] Furthermore, the connection path generation processor calculates the spatial distance between the two elements according to the following formula:

[0019]

[0020] Among them, P i =(x i y i , z i ), representing the logical position of the i-th element;

[0021] The matching degree of the loop rule is obtained directly by calling the loop rule library.

[0022] Furthermore, the loop classification unit includes a loop rule base, a loop attribute analysis processor, and a loop identification processor. The loop rule base is used to store the identification logic for different loop types. The loop attribute analysis processor is used to analyze the connection relationship and determine the loop type. The loop identification processor is used to assign a unique ID and type label to the identified loop.

[0023] The beneficial effects achieved by this invention are:

[0024] This system automatically obtains equipment attributes, location, and function information through code parsing, eliminating the need for manual modeling and significantly reducing drawing design time. It is particularly suitable for the rapid drawing requirements of large-scale electrical engineering projects, improving drawing efficiency. Furthermore, the system automatically generates equipment topology and identifies closed loops, verifying connection logic based on loop rules to effectively avoid omissions, misconnections, and logical errors, thereby improving the engineering reliability of drawings and ensuring loop accuracy.
