Equipment and method for identifying smoke and fire hidden danger of overhead transmission line channel

Abstract

The equipment for identifying the smoke and fire hidden danger of the overhead transmission line channel comprises a storage unit which is configured to store a standard image associated with a target scene, the standard image is at least provided with a first standard area and a second standard area, and the processing priority of the first standard area is higher than that of the second standard area; and a processing unit configured to: obtain a current video frame associated with a target scene; acquiring a first detection area associated with the first standard area in the current video frame; acquiring a first intersection between the two; calculating a first ratio between the first intersection and the first detection area; if the first ratio is greater than or equal to the first effective threshold, maintaining or improving the warning level of the first detection area; otherwise, reducing the warning level of the first detection area. A method is also provided. The method can reduce the adverse effect caused by false alarm, and improves the operation inspection efficiency of the power transmission line.

Description

technical field [0001] The invention belongs to the field of intelligent detection, and in particular relates to a device for identifying hidden dangers of pyrotechnics in channels of overhead transmission lines, and a method for identifying hidden dangers of pyrotechnics in channels of overhead transmission lines. Background technique [0002] Power system transmission inspection is the guarantee for efficient and safe operation of power transmission. In the field of transmission intelligent transportation inspection, the identification accuracy of hidden danger identification has reached a relatively ideal level, and it can accurately identify hidden dangers that may cause harm to transmission lines, such as large mechanical equipment, fireworks, etc. Among all kinds of hidden dangers, fireworks in fields, mountains and forests in dry climates are very harmful to transmission lines, and are the key hidden dangers in the detection of hidden dangers in transmission lines. ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at finding the difference between pyrotechnics and other object characteristics through models in the prior art, so as to reduce the false alarm rate of pyrotechnic hidden dangers, but this method requires huge data for support, and is significantly affected by the environment, especially Clouds, halos, lights, etc. have a high probability of false alarms. On the one hand, we design and provide a device for identifying hidden dangers of pyrotechnics in overhead transmission line channels.
