Description

Technical Field

[0001] This invention relates to the field of intelligent substation commissioning and operation and maintenance technology, specifically to a device and method for generating, printing and verifying labels for all optical cables and fiber optic links in an intelligent substation. Background Technology

[0002] Smart substations generally adopt a "three-layer, two-network" architecture (process layer - bay layer - station control layer). Process layer equipment and bay layer equipment communicate with each other via optical cables and fiber optic links. The labels on all optical cables and fiber optic links in the station are key identifiers for installation, commissioning, acceptance, and subsequent operation and maintenance. Their accuracy directly affects construction efficiency, commissioning cycle, and power grid operation safety.

[0003] Currently, the management process for fiber optic link labels in smart substations is mainly divided into three stages: design, printing, and acceptance. In the design stage, designers create fiber optic connection diagrams and backplane patching diagrams for each bay based on typical design and functional requirements. In the printing stage, printing personnel print various labels and signboards according to certain standards based on the design drawings. In the acceptance stage, secondary acceptance personnel need to visually inspect and verify each link using handheld testers, comparing it with the drawings and signboards.

[0004] However, existing technologies have the following drawbacks: 1) During the design phase, drawings are scattered and lack a unified view across the entire substation, making errors and omissions easy to occur; 2) Printing personnel are not professional staff, which can easily introduce new labeling errors; 3) The acceptance phase relies entirely on manual verification, which is labor-intensive, inefficient, and difficult to guarantee 100% accuracy. These disconnects and human errors pose hidden dangers to the long-term stable operation of substations. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for generating, printing and verifying labels for all optical cables and fiber optic links in a smart substation. This invention achieves closed-loop management from SCD file to physical label generation and verification through automation, enhances the correlation and uniformity of all optical cables and fiber optic links in the substation, reduces human error in each link, greatly improves the efficiency and accuracy of construction and acceptance, and ensures the correctness of the labels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for generating, printing, and verifying labels for all optical cables and fiber optic links in a smart substation, comprising:

[0007] The whole station optical cable and fiber optic link diagram generation module is used to import the SCD file of the smart substation, generate the whole station virtual terminal connection diagram based on the SCD file, and simplify the virtual terminal connection diagram into a fiber optic link diagram that includes all smart devices and their fiber optic connection relationships. Then, by adding cabinet models and equipment models, the whole station optical cable and fiber optic link diagram containing complete physical connection information is generated.

[0008] The label generation and printing module is used to extract the corresponding port and link information from the whole site optical cable and fiber optic link diagram according to the preset label printing rules, automatically generate label printing data and send it to the external label printer for printing.

[0009] The label recognition module is used to acquire the label image of the port to be verified and to identify the label information from the image;

[0010] The GOOSE / SV packet parsing module is used to capture packets on the fiber optic link of the port to be checked through the device's optical port, and parse the captured GOOSE / SV packets to extract link data information.

[0011] The tag comparison module is connected to the whole-site optical cable and fiber optic link diagram generation module, the tag recognition module, and the GOOSE / SV data packet parsing module, respectively. It is used to compare the tag information recognized by the tag recognition module with the corresponding information in the whole-site optical cable and fiber optic link diagram, and perform composite verification by combining the link data information extracted by the GOOSE / SV data packet parsing module, output the verification result, and mark the correctly verified ports on the whole-site optical cable and fiber optic link diagram.

[0012] Furthermore, the whole-site optical cable and fiber optic link diagram generation module converts the logical connection relationship in the virtual terminal connection diagram into a physical optical port connection relationship according to the preset optical port configuration rules, and generates a simplified fiber optic link diagram; then, it adds models of secondary cabinets, control cabinets, fusion splice trays / fiber distribution frames, switches, waveform recording devices and network analysis devices to the simplified fiber optic link diagram, and configures each intelligent device model into the corresponding cabinet model to generate the whole-site optical cable and fiber optic link diagram.

[0013] Furthermore, the optical port configuration rules include:

[0014] The same device sends multiple data packets to the same device using the same optical port;

[0015] The two devices that send and receive data to each other use the same optical port;

[0016] Each device has one network port;

[0017] The link connected to the measurement and control device uses a network port;

[0018] The merging unit receives GOOSE messages from smart terminals via the network interface;

[0019] GOOSE communication between interval layer devices uses a network port;

[0020] Non-networked links use direct sampling ports or direct jump ports.

[0021] Furthermore, the whole-site optical cable and fiber optic link diagram generation module also verifies the generated whole-site optical cable and fiber optic link diagram according to the preset wiring logic; the wiring logic includes: using optical cables to connect different cabinets and adding fusion splice trays; using jumper cables to connect devices within the same cabinet; concentrating the links from the same device to the same cabinet as much as possible on the same fusion splice tray; and not using the same fusion splice tray or pigtail cable for the two sets of intelligent devices with dual configurations.

[0022] Furthermore, it also includes a label printing rule setting module, which is used to set the label printing rules, including the label naming rules and printing format.

[0023] Furthermore, it also includes a hardware module, which is connected to the whole station optical cable and fiber optic link diagram generation module, the label generation and printing module, the label recognition module, and the GOOSE / SV data packet parsing module, respectively. The hardware module has an optical port, a printing interface, and an image acquisition unit, which is used to import the SCD file of the smart substation into the whole station optical cable and fiber optic link diagram generation module, drive the label printer to print labels through the printing interface, acquire the label image of the port to be verified through the image acquisition unit, and capture packets of the fiber optic link of the port to be verified through the optical port.

[0024] This invention also provides a method for generating, printing, and verifying labels for all optical cables and fiber optic links in a smart substation, applied to the aforementioned device. The method includes the following steps:

[0025] S1: Import the SCD file of the intelligent substation and generate a virtual terminal connection diagram of the entire station based on the SCD file;

[0026] S2: Simplify the virtual terminal connection diagram of the entire station into a simplified optical fiber link diagram, and add cabinet models and equipment models to generate a diagram of optical cables and optical fiber links for the entire station;

[0027] S3: Based on the preset label printing rules, extract the corresponding port and link information from the whole site optical cable and fiber optic link diagram, automatically generate labels and print them;

[0028] S4: Tag verification stage, acquire the tag image of the port to be verified and identify the tag information therein;

[0029] Packet capture is performed on the fiber optic link of the port to be verified, and the captured GOOSE / SV data packets are parsed to extract link data information;

[0030] The identified tag information and extracted link data information are compared and verified with the corresponding information stored in the whole station optical cable and fiber optic link diagram.

[0031] If the verification is correct, mark the port as verified on the entire site's optical cable and fiber optic link diagram, until all ports on the entire diagram have been verified.

[0032] Further, step S2 includes:

[0033] By applying preset optical port configuration rules, the logical signal transmission / reception relationships in the virtual terminal connection diagram are mapped to the connection relationships between the physical optical ports of smart devices, so as to generate a simplified optical fiber link diagram.

[0034] Based on the type and location information of the smart device, its model is configured into the corresponding secondary screen or control cabinet model;

[0035] In the fiber optic connection path between smart devices, insert fusion splice trays / fiber optic distribution frames or switch models according to the connection distance and position relationship.

[0036] Based on the location relationship of the cabinets and the cabling specifications, determine whether the connection medium is optical fiber, pigtail cable or patch cord, and complete the connection between the models to generate a full-site optical fiber and fiber optic link diagram.

[0037] Further, in step S3, the automatic generation and printing of labels includes:

[0038] From the overall optical cable and fiber optic link diagram, extract the tag information of the optical cable / tail cable, the tag information of each optical fiber in the optical cable / tail cable, the tag information of the patch cord, and the tag information of the spare fiber core.

[0039] The extracted information is arranged and combined according to a preset format to generate print data suitable for different types of labels and then printed.

[0040] Furthermore, in step S4, when the identified tag information is consistent with the corresponding information in the whole station optical cable and fiber optic link diagram, and the communication parameters in the extracted link data information match the virtual terminal connection relationship defined in the SCD file, the port tag is determined to be correct.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. Unified source and high accuracy: This invention automatically generates link diagrams and tags based on a unique SCD file across the entire site, ensuring the accuracy and uniqueness of the data source and eliminating design and drawing errors at the source.

[0043] 2. High degree of automation and improved efficiency: This invention realizes full automation or strong assistance of the entire process from drawing generation and label printing to acceptance verification, which greatly reduces manual participation and repetitive work in the design, printing and acceptance stages, and significantly improves work efficiency.

[0044] 3. Intelligent verification, eliminating omissions: This invention uses image recognition and data packet parsing technology for automated verification, which is more reliable and faster than traditional manual verification. It can also intuitively display the verification progress through a graphical interface, effectively avoiding omissions.

[0045] 4. Complies with the design principles of intelligent substations: This invention conforms to the core principle of intelligent substations, namely "source-end modification and process control", and realizes digital management and closed-loop control of engineering data.

[0054] like Figure 1 As shown, this embodiment provides a device for generating, printing, and verifying labels for all optical cables and fiber optic links in a smart substation. The device includes a whole-station optical cable and fiber optic link diagram generation module, a label printing rule setting module, a label generation and printing module, a label recognition module, a GOOSE / SV data packet parsing module, a label comparison module, and a hardware module.

[0055] The whole station optical cable and fiber optic link diagram generation module is used to import the SCD (System Configuration Description) file of the smart substation, generate a whole station virtual terminal connection diagram based on the SCD file, and simplify the virtual terminal connection diagram into a fiber optic link diagram that includes all smart devices and their fiber optic connection relationships. Then, by adding cabinet models and equipment models, a whole station optical cable and fiber optic link diagram containing complete physical connection information is generated.

[0056] Specifically, the whole-site optical cable and fiber optic link diagram generation module converts the logical connection relationships in the virtual terminal connection diagram into physical optical port connection relationships according to preset optical port configuration rules, generating a simplified fiber optic link diagram. The optical port configuration rules include:

[0057] 1) The same device sends multiple data packets to the same device using the same optical port;

[0058] 2) The two devices that transmit and receive data use the same optical port;

[0059] 3) Each device has one network port;

[0060] 4) The link connected to the measurement and control device uses a network port;

[0061] 5) The merging unit receives GOOSE messages from smart terminals via the network interface;

[0062] 6) GOOSE communication between bay-layer devices uses a network port;

[0063] 7) Non-networked port links use direct sampling ports or direct jump ports.

[0064] Then, add models of secondary switch cabinets, control cabinets, fiber optic patch panels / fiber optic distribution frames, switches, waveform recording devices, and network analysis devices to the simplified fiber optic link diagram, and configure each intelligent device model into the corresponding switch cabinet model to generate a full-site optical cable and fiber optic link diagram.

[0065] The whole-site optical cable and fiber optic link diagram generation module also verifies the generated whole-site optical cable and fiber optic link diagram according to the preset cabling logic. The cabling logic includes: using optical cables to connect different cabinets and adding fusion splice trays; using jumper cables to connect devices within the same cabinet; concentrating the links from the same device to the same cabinet on the same fusion splice tray as much as possible; and not using the same fusion splice tray or pigtail cable for two sets of intelligent devices with dual configurations.

[0066] The label printing rule setting module is used to set the label printing rules, including the label naming rules and printing format.

[0067] The label generation and printing module is used to extract the corresponding port and link information from the whole station optical cable and fiber optic link diagram according to the preset label printing rules, automatically generate label printing data and send it to the external label printer for printing.

[0068] The label recognition module is used to acquire the label image of the port to be verified and to identify the label information from the image.

[0069] The GOOSE / SV packet parsing module is used to capture packets on the fiber optic link of the port to be checked through the optical port of the device, and to parse the captured GOOSE / SV packets to extract link data information.

[0070] The tag comparison module is connected to the whole-site optical cable and fiber optic link diagram generation module, the tag recognition module, and the GOOSE / SV data packet parsing module, respectively. It is used to compare the tag information recognized by the tag recognition module with the corresponding information in the whole-site optical cable and fiber optic link diagram, and perform composite verification by combining the link data information extracted by the GOOSE / SV data packet parsing module, output the verification result, and mark the correctly verified ports on the whole-site optical cable and fiber optic link diagram.

[0071] The hardware module is connected to the whole-station optical cable and fiber optic link diagram generation module, the label generation and printing module, the label recognition module, the GOOSE / SV data packet parsing module, and the label printing rule setting module, respectively. It has an optical port, a printing interface, an image acquisition unit, and input / output devices. It is used to import the SCD file of the smart substation into the whole-station optical cable and fiber optic link diagram generation module, drive the label printer to print labels through the printing interface, acquire the label image of the port to be verified through the image acquisition unit, capture packets of the fiber optic link of the port to be verified through the optical port, and input the label printing rules and display the image through the input / output devices.

[0072] The device is integrated into a digital relay protection tester.

[0073] This embodiment also provides a method for generating, printing, and verifying labels for all optical cables and fiber optic links in a smart substation, applied to the aforementioned device, and its specific implementation steps are as follows.

[0074] S1: Import the SCD file of the intelligent substation and generate a virtual terminal connection diagram of the entire station based on the SCD file.

[0075] S2: Simplify the entire site's virtual terminal connection diagram into a simplified fiber optic link diagram, and add cabinet and equipment models to generate a complete site optical cable and fiber optic link diagram; specifically including:

[0076] 1) Apply the preset optical port configuration rules to map the logical signal transmission / reception relationship in the virtual terminal connection diagram to the connection relationship between the physical optical ports of the smart devices, so as to generate a simplified optical fiber link diagram;

[0077] 2) Based on the type and location information of the intelligent device, configure its model into the corresponding secondary screen or control cabinet model;

[0078] 3) In the fiber optic connection path between intelligent devices, insert fusion splice trays / fiber optic distribution frames or switch models according to the connection distance and position relationship;

[0079] 4) Based on the location relationship of the cabinets and the cabling specifications, determine whether the connection medium is optical fiber, pigtail cable or patch cord, and complete the connection between the models to generate a full-site optical fiber and fiber optic link diagram.

[0080] S3: Based on the preset label printing rules, extract the corresponding port and link information from the whole site optical cable and fiber optic link diagram, automatically generate labels and print them.

[0081] Specifically, from the overall optical cable and fiber optic link diagram, the tag information of the optical cable / tail cable, the tag information of each optical fiber in the optical cable / tail cable, the tag information of the patch cord, and the tag information of the spare fiber core are extracted respectively; then, the extracted information is arranged and combined according to the preset format to generate printing data suitable for different types of tags and printed.

[0082] S4: In the tag verification stage, acquire the tag image of the port to be verified and identify the tag information; capture packets of the fiber optic link of the port to be verified, and parse the captured GOOSE / SV data packets to extract link data information; compare and verify the identified tag information and extracted link data information with the corresponding information stored in the whole-site optical cable and fiber optic link diagram; if the verification is correct, mark the port as verified on the whole-site optical cable and fiber optic link diagram, until the verification of all ports in the diagram is completed. Specifically, when the identified tag information matches the corresponding information in the whole-site optical cable and fiber optic link diagram, and the communication parameters in the extracted link data information match the virtual terminal connection relationship defined in the SCD file, the port tag is determined to be correct.

[0083] In this embodiment, the SCD is parsed and a full-site virtual terminal connection diagram is generated, such as... Figure 2 As shown.

[0084] The whole-site optical cable and fiber optic link diagram generation module is the core module of this device. This module gradually generates the whole-site optical cable and fiber optic link diagram based on the whole-site virtual terminal connection diagram. For example... Figure 3 As shown, in Figure 2 Based on the overall virtual terminal connection diagram of the intelligent station, and according to the relevant knowledge and procedures of the intelligent station process layer, the following optical port configuration rules are set to gradually generate a simplified optical fiber link diagram:

[0085] Serial Number Generation rules Corresponding sub-image 1 Multiple data packets are sent from the same device using the same optical port. Figure 3 (a) 2 Two devices that send and receive data use the same optical port. Figure 3 (a) 3 Each device has a fixed network port. Figure 3 (b) 4 All devices connected to the measurement and control system use network ports; Figure 3 (b) 5 The merging unit receives the smart terminal GOOSE using a network port; Figure 3 (b) 6 GOOSE uses network ports to connect the inter-layer devices; Figure 3 (b) 7 Those that do not use a network interface should use a direct sampling or direct jump interface; Figure 3 (b) 8 The definition of virtual terminals in SCD and the above principles can be used to configure the relevant optical ports. Figure 3 (c) 9 The remaining output ports need to be entered by personnel according to the design drawings. Figure 3 (d)

[0086] Note: (1) Figure 3 In Figure (a), SV 0X4001 identifies the SV control block and data packet, and GOOSE 0X1001 identifies the GOOSE control block and data packet; (2) Figure 3 In Figure (b), 1X in 1XA indicates the first plug-in of the intelligent device (protection device, measurement and control device, merging unit, intelligent terminal), and A represents the Ath optical port of the plug-in. The specific optical port varies depending on the device; (3) Figure 3 In Figure (c), 1X1 represents the first optical port of the first plug-in of the device. Here, 1X1 is used to refer to the networking port. If the actual networking port does not receive virtual terminals, it also needs to be manually set. (4) The different generation rules will directly affect the number of optical fiber links in the actual process layer. If the entire station does not use networking, then the rules related to the networking port can be left unselected. These rules can be combined into corresponding functional modules for design and debugging personnel to select. For detailed rules, there is no need to select each one.

[0087] like Figure 4 As shown, finally Figure 3 The fiber optic link diagram in Figure (d) further refines the relevant information, mainly including the following:

[0088] (1) Place the intelligent device into the corresponding intelligent control cabinet or secondary screen. The intelligent control cabinet does not need to contain secondary room information, while the secondary screen must contain secondary room information.

[0089] Serial Number Secondary chamber Screen cabinet name 1 220kV equipment compartment (220kV protection compartment) XXJ 220kV XX line protection and control panel 2 - 220kV XX line intelligent control cabinet

[0090] (2) Optical fiber connections between secondary rooms and equipment areas, and between equipment areas, are made using optical cables. That is, optical cables are used between secondary screens and control cabinets, and between control cabinets. Fiber optic splicing trays are required between screens / cabinets. Equipment within a screen / cabinet is directly connected using jumper cables, i.e., using a transmit / receive pair of optical fibers. Secondary screens within the same secondary room can be connected using pigtail cables; no fiber optic splicing trays are required. Note that optical cables are also used between secondary screens in different secondary rooms, requiring additional fiber optic splicing trays.

[0091] (3) The same smart device to the same cabinet should be in the same fiber optic cable (optical cable) and tail cable, and the location area should be in the same block; the two sets of smart devices with dual configuration should not be in the same fiber optic cable (optical cable) and tail cable, and the same set of smart devices should be in the same fiber optic cable (optical cable) and tail cable as much as possible.

[0092] Serial Number Equipment types Specification 1 ODF (Optical Discharge Fabrication Unit) The main types are 12-core and 24-core, with a small number of 4-core, 6-core, and 8-core. 2 optical cable Mainly 12-core and 24-core 3 Tail cable Mainly 4-core, 6-core, and 12-core 4 Prefabricated optical cable Mainly 4-core, 8-core, 12-core, and 24-core

[0093] (4) The process layer switch is installed in a secondary panel in the secondary room and is connected in a radial connection manner according to points (2) and (3);

[0094] (5) Intelligent devices, fiber optic assemblies, switches, and other equipment should all be assigned device numbers, such as Figure 4 The protection devices 1-1n and the measurement and control devices 2n are included.

[0095] (6) The above steps can be generated manually step by step, or automatically generated by setting corresponding rules, and then corrected by checking and logical verification.

[0096] like Figure 5 As shown, the automatic generation of labels requires extracting the information contained in the optical fiber link diagram of the entire station, arranging and combining it in a fixed format, and finally generating tags for optical cables / tail cables, labels for optical cables / tail cables, labels for jumpers, and labels for spare fiber cores. Figure 5 In the image, (a) is the tag for the optical cable / tail cable, (b) is the tag for the optical cable / tail cable fiber core, (c) is the tag for the jumper fiber, and (d) is the tag for the spare fiber core.

[0097] For easy viewing and editing, the function of generating a full-site optical fiber link diagram can be completed on the computer software. Labels can also be directly output and printed from the computer software, and then the computer software can output a file of a specific format for import into the debugging instrument, which can then verify the labels.

[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
