Digital substation metering operation inspection auxiliary method based on AR technology

Abstract

The invention discloses a digital substation metering operation inspection auxiliary method based on an AR technology. The method comprises the following steps of: in the operation and inspection process of a digital transformer substation, allowing workers to wear AR intelligent glasses, collecting and sending a field device two-dimensional code, a field device picture and video, field device parameters and worker voice information to a mobile phone operation inspection APP terminal for off-line analysis; or enabling the mobile phone operation and maintenance APP terminal to upload the information to the Web background system for network cloud analysis to obtain a solution, and then issuing an instruction to the AR intelligent glasses to guide the workers to perform fault processing and next operation and maintenance work. According to the invention, the AR glasses, the mobile phone operation inspection APP terminal and the Web background system are connected together in a wireless and wired manner, data information interaction is achieved, the safety and real-time performance of inspection operation are improved, the development process of achieving comprehensive automation of the intelligent substation is promoted to be presented in an augmented reality mode, and the method has great application value for metering, operation and inspection work of the digital substation.

Description

technical field [0001] The invention relates to an AR technology-based auxiliary method for measurement and inspection of digital substations, and belongs to the technical field of inspection methods for substations. Background technique [0002] Digital (smart) substations, due to the use of optical fiber digital communication, compared with traditional substations, the entire metering device has undergone major changes in related equipment, inspection and maintenance work, and current metering professionals are facing many difficulties. At present, a small number of enterprises are still in the state of manual registration and statistics of equipment information for management work, and some enterprises are using more advanced electronic PDA handheld devices for inspections, which will cause the following problems: [0003] (1) Missed inspections occur, and the workload of the inspection process is very huge. Missed equipment inspections and data management errors are inev...

AI Technical Summary

Problems solved by technology

[0003] (1) Missed inspections occur, and the workload of the inspection process is very huge. Missed equipment inspections and data management errors are inevitable;

[0004] (2) The real-time performance of the data is poor. The inspection personnel cannot obtain the inspection standard information in real time, and it is more difficult to locate defects. The management department cannot obtain the statistical analysis results of the inspection in time, and cannot guarantee the accuracy and consistency of management;

[0005] (3) The data is isolated and lacks correlation, and a large amount of data is generated during the inspection process, but the inspection data is isolated, without intelligent correlation analysis, and cannot effectively manage potential safety hazards in a preventive manner;

[0006] (4) The quality requirements of personnel are too high. With the popularization of digital (intelligent) substations, the difficulty of power inspection is further increased, and the professional knowledge of on-site inspection personnel is required to be higher, which increases the labor cost and error rate of inspection.
