This embodiment is applicable to situations requiring efficient and accurate detection of secondary circuits in substations. The method can be executed by a secondary circuit detection device, which can be implemented in software and / or hardware, and is generally integrated into an electronic device. This electronic device can be a terminal device or a server device; the present invention does not limit the specific type of electronic device. Correspondingly, as...

[0038] The secondary circuit under test can be an electrical circuit formed by interconnecting secondary equipment to detect, control, regulate, and protect sequentially used equipment. This mainly includes tripping within the current compartment, tripping of other compartments, and startup failure. The physical image of the secondary wiring can be obtained by capturing images of the wiring configuration within the substation protection cabinet using photographic equipment. The schematic image of the secondary wiring can be a circuit diagram provided by the secondary circuit manufacturer.

[0039] In this embodiment of the invention, a photographic device can be used to capture images of the wiring configuration of the secondary circuit to be tested in a substation protection panel, obtaining a physical image of the secondary wiring. The secondary wiring principle image can be drawn by the secondary circuit manufacturer and acquired via document file reception.

[0040] S120. Perform image recognition on the secondary wiring entity image to obtain a secondary wiring entity recognition image, and perform image recognition on the secondary wiring principle image to obtain a secondary wiring principle recognition image.

[0041] The secondary wiring entity recognition image can be obtained by processing the secondary wiring entity image using an image recognition algorithm. The secondary wiring principle recognition image can also be obtained by processing the secondary wiring principle image using an image recognition algorithm.

[0042] In this embodiment of the invention, the secondary wiring entity identification image is processed by an image recognition algorithm to extract the manufacturer's internal wiring wire number set, external cable wire number set, and protection cabinet name information from the secondary wiring entity identification image. Then, a secondary wiring entity identification image is generated from the manufacturer's internal wiring wire number set, external cable wire number set, and protection cabinet name information from the secondary wiring entity identification image. Similarly, the secondary wiring principle identification image is processed by an image recognition algorithm to extract the manufacturer's internal wiring wire number set and trip entry point information from the secondary wiring principle identification image. Then, a secondary wiring principle identification image is generated from the manufacturer's internal wiring wire number set and trip entry point information from the secondary wiring principle identification image.

The reference identifier can be an identifier that uniquely identifies the wiring number sleeve in the secondary circuit. The standard connection component can be a component used to indicate the connection of the wiring terminal to the internal wiring.

[0045] In this embodiment of the invention, the reference identifier of the reference component in the secondary circuit to be detected is obtained from the secondary wiring entity recognition image obtained by the above steps. It is easy to understand that the reference identifier can uniquely identify a reference component, and the standard connection component that matches the reference identifier can be uniquely identified based on the reference identifier of the reference component.

[0046] S140. Construct a reconstructed secondary loop structure diagram of the secondary loop to be detected based on the reference component and the standard connection component.

[0047] Among them, the reconstructed secondary loop structure diagram can be a relational image used to represent the connection relationship between the reference component and the standard connection component.

[0048] In this embodiment of the invention, by obtaining the reference component, standard connection component, and mapping relationship between the reference component and the standard connection component in the image based on the above steps, a reconstructed secondary circuit structure diagram matching the secondary circuit to be detected can be obtained. The reconstructed secondary circuit structure diagram may include, but is not limited to, information on internal wiring numbers and external cable numbers from the manufacturer.

[0049] S150. The reconstructed secondary circuit structure diagram is detected based on the secondary wiring principle image to obtain the detection result of the secondary circuit to be detected.

[0050] In this embodiment of the invention, after obtaining the reconstructed secondary circuit structure diagram, it can be used as the structure diagram of the secondary circuit to be tested. The reconstructed secondary circuit structure diagram is then tested based on the secondary wiring principle image, for example, to determine whether the connections between various circuit components in the reconstructed secondary circuit structure diagram are correct, thereby obtaining the test result of the secondary circuit to be tested. Simultaneously, the reconstructed secondary circuit structure diagram is printed so that it can be pasted inside the protective enclosure for display.

[0051] The technical solution of this invention involves acquiring a physical image of the secondary wiring and a schematic image of the secondary wiring of the secondary circuit to be tested. Image recognition is performed on the physical image to obtain a secondary wiring entity recognition image. Image recognition is also performed on the schematic image to obtain a secondary wiring principle recognition image. Based on the secondary wiring entity recognition image, a reference identifier for a reference component in the secondary circuit to be tested is determined, and a standard connection component matching the reference identifier is identified. A reconstructed secondary circuit structure diagram matching the secondary circuit to be tested is constructed based on the reference component and the standard connection component. Finally, the reconstructed secondary circuit structure diagram is tested based on the schematic image of the secondary wiring to obtain the test result of the secondary circuit to be tested. This solution solves the problem of a lack of efficient verification methods for secondary circuits, saves labor costs, and improves the efficiency and accuracy of secondary circuit testing.

The secondary wiring principle recognition image is also processed by an image recognition algorithm to extract the manufacturer's internal wiring wire number set and trip entry point information. Then, a secondary wiring principle recognition image is generated from the manufacturer's internal wiring wire number set and trip entry point information.

[0060] S230. Determine the reference identifier of the reference component in the secondary circuit to be detected based on the secondary wiring entity recognition image, and determine the standard connection component that matches the reference identifier.

[0062] The reference external wire number sleeve can be a wire number sleeve wound on the external cable in the substation protection cabinet. The reference external wire number sleeve identifier can be an identifier that uniquely identifies one reference external wire number sleeve. The preset mapping relationship table can be a diagram used to show the association between the reference external wire number sleeve and the external wire number sleeve connection components. The first standard connection component can be a relay protection component connected to the reference external wiring.

[0063] In this embodiment of the invention, firstly, the mapping relationship between the external wire number sleeve identifier and the external wire number sleeve connection component is obtained according to the external wire number sleeve identifier and the external wire number sleeve connection component. Then, a preset mapping relationship table is obtained according to the external wire number sleeve identifier, the external wire number sleeve connection component, and the mapping relationship between the external wire number sleeve identifier and the external wire number sleeve connection component. The reference external wire number sleeve identifier is matched with the preset mapping relationship table. Based on the matching result, the first standard connection component and the second standard connection component connected to the left and right ends of the reference external line where the reference external wire number sleeve identifier is located are determined.

[0064] S240. Construct a reconstructed secondary loop structure diagram of the secondary loop to be detected based on the reference component and the standard connection component.

[0067] Figure 5 This is a schematic diagram of a reconstructed secondary loop structure provided in Embodiment 2 of the present invention. In a specific example, such as... Figure 5 As shown, the above steps determine that the first standard connection component matching the reference external wire number sleeve identifier "EMB-103 / 133R" is "1LP5-1". Then, the first connection relationship between the first standard connection component and the reference external wire number sleeve is determined, and the reference external wire number sleeve "EMB-103 / 133R" and the first standard connection component "1LP5-1" are connected based on this first connection relationship.

The reference external wire number sleeve "EMB-103 / 101" and the second standard connection component "4n1" are connected based on this second connection relationship, finally yielding the reconstructed secondary loop structure diagram of the reference external wire number sleeve.

[0068] S250. The reconstructed secondary circuit structure diagram is detected based on the secondary wiring principle image to obtain the detection result of the secondary circuit to be detected.

[0069] In an optional embodiment of the present invention, the step of detecting the reconstructed secondary circuit structure diagram based on the secondary wiring principle image may include: determining the mapping relationship to be detected between the trip entry point, internal wiring and external cable in the reconstructed secondary circuit structure diagram; determining the reference mapping relationship between the trip entry point, internal wiring and external cable in the secondary wiring principle image; and determining that the reconstructed secondary circuit structure diagram passes the preliminary detection if the mapping relationship to be detected matches the reference mapping relationship.

[0070] In this embodiment of the invention, the one-to-one mapping relationship between the trip entry point, internal wiring, and external cable in the reconstructed secondary circuit structure diagram is determined based on the reconstructed secondary circuit structure diagram and used as the mapping relationship to be tested. The one-to-one mapping relationship between the trip entry point, internal wiring, and external cable in the secondary wiring principle image is determined based on the secondary wiring principle image and used as the reference mapping relationship. The mapping relationship to be tested is matched with the reference mapping. If the matching fails, it is determined that the reconstructed secondary circuit structure diagram has failed the preliminary test; if the matching is successful, it is determined that the reconstructed secondary circuit structure diagram has passed the preliminary test.

[0071] In an optional embodiment of the present invention, after determining that the reconstructed secondary circuit structure diagram has passed the preliminary test, the method may further include: acquiring the protection configuration data of the secondary circuit to be tested; matching the target secondary circuit standard database from each secondary circuit standard database according to the protection configuration data of the secondary circuit to be tested; acquiring the circuit structure data of each standard secondary circuit and the standard security association configuration data of each standard secondary circuit; reorganizing the protection configuration information of the circuit structure of the standard secondary circuit according to the standard security association configuration data to obtain the secondary circuit standard database. The method further includes acquiring the secondary circuit network diagram stored in the target secondary circuit standard database; wherein the secondary circuit network diagram includes standard protection configuration data; and matching the protection configuration data to be tested with the secondary circuit network diagram to detect the security compliance of the reconstructed secondary circuit structure diagram.

[0073] In this embodiment of the invention, firstly, the protection configuration data of the secondary circuit to be tested is obtained. Then, the protection configuration data of the secondary circuit to be tested is used to match the target secondary circuit standard database in the secondary circuit standard database to obtain the circuit structure data and standard safety association configuration data of each standard secondary circuit. Next, the protection configuration information of the circuit structure of the standard secondary circuits is reconstructed according to the standard safety association configuration data to obtain the secondary circuit standard database. Further, the secondary circuit network diagram stored in the target secondary circuit standard database is obtained; the protection configuration data to be tested is matched with the secondary circuit network diagram. If the match is successful, the reconstructed secondary circuit structure diagram complies with safety compliance; if the match fails, the reconstructed secondary circuit structure diagram does not comply with safety compliance.

If it is determined that there is an abnormal result in the detection result of the secondary circuit to be tested, an abnormal alarm shall be triggered; wherein, the abnormal result includes abnormality of the standard connection component and / or abnormality of circuit missing component.

[0075] Among these, a standard connection component malfunction can occur when only one end of the connection component is properly connected. A loop defect malfunction can occur when a loop fails to close properly.

[0076] In this embodiment of the invention, it is determined whether the detection result of the secondary circuit to be tested is abnormal. If it is determined that it is not abnormal, the connection of the secondary circuit to be tested is normal. If it is determined that it is abnormal, an abnormal alarm is triggered. The abnormal alarm includes, but is not limited to, issuing an abnormal error correction alarm signal or illuminating a red light, so as to serve as a warning.

[0077] Figure 6 This is a structural diagram of a secondary loop detection system provided in Embodiment 2 of the present invention. Figure 6As shown, the system first imports the physical image of the secondary circuit's secondary wiring using the image import and extraction module, and then imports the image of the secondary circuit's secondary wiring principle using the drawing import and extraction module. A key data comparison module is then used for comparison. After the key data comparison is completed, a standard database management module is used for matching. For mismatched secondary circuits, an anomaly correction and alarm module is used to issue an anomaly alarm. Alternatively, based on the user-selected single maintenance relay protection device, the system can automatically identify the key terminals of the operating equipment and activate the maintenance status early warning function, illuminating a red light to serve as a warning. Finally, the reconstructed secondary circuit structure diagram is exported using the data result export module.

[0078] The technical solution of this invention involves acquiring a physical image of the secondary wiring and a schematic image of the secondary wiring of the secondary circuit to be tested. Image recognition is performed on the physical image to obtain a secondary wiring entity recognition image. Image recognition is also performed on the schematic image to obtain a secondary wiring principle recognition image. Based on the secondary wiring entity recognition image, a reference identifier for a reference component in the secondary circuit to be tested is determined, and a standard connection component matching the reference identifier is identified. A reconstructed secondary circuit structure diagram matching the secondary circuit to be tested is constructed based on the reference component and the standard connection component. Finally, the reconstructed secondary circuit structure diagram is tested based on the schematic image to obtain the test result of the secondary circuit to be tested. If an abnormal result is found in the test result of the secondary circuit to be tested, an abnormal alarm is triggered. By matching the schematic image of the secondary wiring with the reconstructed secondary circuit structure diagram, efficient verification of the secondary circuit is achieved, saving labor costs and improving the efficiency and accuracy of secondary circuit testing.
