[0025] In order to better understand the technical solution of the present invention, the following is a detailed description through specific embodiments:

[0026] A method for maintaining substation equipment and location names by using a virtual reality device of the present invention is characterized by comprising the following steps:

[0027] S1, build a virtual model of substation equipment and storage space;

[0028] S2, using machine learning methods, intelligently identifies and labels virtual models through photos of equipment locations with nameplates, and inputs the recognition learning results into the VR head display device;

[0029] S3, the inspectors wear VR headsets to conduct inspections and enter the warehouse nameplate data.

[0030] In S1, the virtual model of substation equipment and positions is built based on the BIM model in the substation design stage, including high-voltage switchgear positions, transformer equipment, and low-voltage switchgear positions. The virtual model includes the nameplate position 1. Figure 1 This is the basis for nameplate recognition using machine learning.

[0031] In S2, the equipment location photos are diverse sample photos, including locations of different circuits, busbar sections, open equipment and closed equipment, top busbars and transformer equipment. The system can learn and identify nameplate features, automatically capture and recognize text information, and accurately draw equipment names. At the same time, the system can learn based on historical data to determine whether the nameplate on the equipment location meets the specifications, and prevent missing affixes and incorrect location names and locations. For example, the recognition accuracy of the different locations and methods of affixing nameplates of capacitors, feeders, and high-voltage equipment of different models and manufacturers should be no less than 95%.

[0032] In S3, before the inspection, the operation and maintenance personnel need to wear VR headsets for preliminary training, and then enter the station for daily inspections and enter the corresponding warehouse nameplate data. The inspection path is input into the VR headset in advance, and the inspectors inspect the equipment in the station one by one based on the path and the arrow prompts of the VR headset. For the warehouses and nameplates that have been missed, the VR headset will mark them 2, and for the warehouses and nameplates that have been scanned, the VR headset will mark them 3. Figure 2 and Figure 3 .

[0033] See also Figure 4 The VR headset device checks the historical data to determine whether the nameplate on the equipment position is logical and meets the standard naming requirements for the position nameplate. Nameplates that do not meet the naming requirements will also be marked.

[0034] After completing the inspection of the entire route, the VR headset generates a multi-format warehouse layout diagram of the inspection area based on the scan results, such as PDF, CAD, etc. At the same time, the warehouse nameplate data information is updated based on the same source database to achieve a single source of data. The operator realizes the warehouse layout during the inspection process. Figure 1 Key generation.

[0035] The VR headset is connected to the backend server via wireless transmission, and transmits the entered warehouse nameplate data and warehouse layout data to the backend server. The backend server verifies the rationality of the inspection through manual intervention, and corrects the inspection and equipment problems in a timely manner.

[0036] Through the management of background data, before-and-after comparisons can be made, and a model based on the historical timeline can be generated to trace the position changes before and after. Based on the i State Grid platform, the latest data of the substation is transmitted, distributed and shared in real time.

[0037] The system supports operations such as adding, deleting, modifying and checking device names, and can intelligently identify and prompt potential errors or inconsistencies. At the same time, the system can automatically record the records of each maintenance operation for subsequent auditing and tracing. Display and interact with device information through virtual reality devices: Users can view device information in virtual models through virtual reality devices, including detailed information such as device name, specifications, and manufacturer. The system provides interactive functions, allowing users to query and operate device information, realizing intuitive display of information and interactive operations.

[0038] From the above description, it can be seen that the present invention improves work efficiency and accuracy, reduces the error rate of manual operation, and provides a new solution for the operation and maintenance management of the power system by using virtual reality equipment to draw the substation equipment and the storage name maintenance method.

[0039] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
