AI Technical Summary

Technical Problem

Traditional substation operation risk identification methods rely on manual observation and experience-based judgment, which are intermittent and subjective, making it difficult to achieve continuous, objective, and accurate monitoring. Furthermore, traditional monitoring methods suffer from blind spots and low positioning accuracy, failing to meet the requirements for high-precision and high-reliability risk identification.

Method used

By combining multi-view video with high-precision positioning, multiple fixed-view cameras and mobile video acquisition devices are deployed to acquire video of the work site. Combined with a high-precision positioning system and a three-dimensional digital twin model, the three-dimensional spatial coordinates of the workers and equipment are determined and real-time dynamic images are generated. Real-time risk assessment and early warning are then performed using spatiotemporal fusion algorithms and risk assessment algorithms.

Benefits of technology

It enables comprehensive, blind-spot-free monitoring of substation work sites, improves positioning accuracy and risk identification accuracy, provides timely and effective risk warnings, and enhances the level of safety management at work sites.

Abstract

The invention relates to a substation operation risk identification method based on a multi-view video and high-precision positioning. Acquiring video data of a working site through a plurality of cameras with fixed visual angles and mobile video acquisition equipment; a high-precision positioning system is used for obtaining three-dimensional space coordinates of operators and equipment in real time; establishing a three-dimensional digital twinborn model of the substation equipment, and performing dynamic scene reconstruction based on the multi-view video stream to generate a real-time three-dimensional scene of the operation site; fusing the positioning data and the three-dimensional scene by adopting a space-time fusion algorithm to generate a dynamic digital portrait of the operator; and carrying out real-time analysis on behaviors and positions of operators by using a risk assessment algorithm based on a preset risk rule, calculating to obtain a risk assessment value, and setting a feedback mechanism to continuously optimize positioning and scene reconstruction precision. According to the invention, efficient, accurate and real-time identification and early warning of the operation risk of the transformer substation are realized, and the safety management level of an operation site is effectively improved.
