Description
Technical Field
The invention belongs to the technical field of power transmission line inspection, and particularly relates to a method for overhauling an underground cable based on virtual reality.
Background
The cable is mainly used as a carrier for transmitting electric power, consists of single-strand or multi-strand wires and an insulating layer, and is arranged to convey the electric power from a power plant to a user unit so as to facilitate the production and living use of the user unit. After entering modern society, due to the reasons of shortage of urban land, high traffic pressure, urban construction and the like, underground cable power transmission is commonly adopted in large cities. Compared with an overhead line, the cable has the advantages of small occupied area, reliable power transmission, strong anti-interference capability and the like.
The underground cable is an important component of national economic infrastructure, is a life line of a city, is responsible for transmitting light and energy for thousands of households, is an important support for guaranteeing economic development and normal production and life of common people, and the maintenance operation of the underground cable becomes an important content of daily operation and maintenance work of a power grid.
The traditional maintenance treatment mode mainly comprises two modes of manual line inspection maintenance and early fault judgment cognitive maintenance. Manual inspection requires a large amount of manpower and time to perform manual investigation, and identification and judgment are performed after abnormality is determined, and then disposal is performed. And (3) early fault judgment cognitive maintenance, namely performing operation maintenance on the underground cable according to different angles of monitoring of power grid parameters by adopting an early judgment mode based on an early fault model, a wavelet transformation method and a Bayesian method.
The manual line patrol inspection only depends on manual identification, so that the efficiency is low inevitably, a large amount of manual errors exist when large data volume is processed, the manual line patrol inspection is basically not suitable for operation, inspection and processing of a large amount of underground cables, in addition, the workload is huge, the efficiency is low, the weight checking accuracy is extremely low, and a large amount of human resources are consumed.
The early failure judgment cognitive maintenance mode is used for carrying out abstract evaluation on the cable operation data, the calculation times are huge when the cable data with large data volume is processed, the evaluation model period is too long, and the efficiency is low. When the underground line operation maintenance processing is carried out, due to the existence of time resolution, frequency resolution and statistical errors of data, invalid information identification can occur, so that abnormal information is omitted; the early fault judgment cognitive maintenance mode can only find abnormal data under the condition of a specific model and cannot analyze and screen all operation data information. When the amount of data to be processed is large, the processing efficiency is still low, and the accuracy is low and can only reach about 60%.
Therefore, it is urgently needed to develop a method for overhauling an underground cable based on virtual reality to solve the problems.
