Benefits of technology

This patented technology allows users to easily recognize if two electrical components (a movable contact arm or stationary contact) have been opened/closed during certain times based on their images taken from different angles. It does this through calculating connections between these images and comparing them with previous ones beforehand. By doing this it saves time and effort compared to requiring extensive samples that require trained operators' hours. Additionally, multiple values may also be added to increase its effectiveness but at lower costs than traditional methods such as grey algorithms. Overall, this approach provides efficient identification capabilities while reducing complexity and improving efficiency over existing systems.

Problems solved by technology

The technical problem addressed in this patented technology relates to identifying when certain parts within images are blocked from view during power transmission operations without causing false alarms caused by incorrect movement of these blocking elements.

Abstract

The invention discloses an on-off state image recognition method for a high-voltage double-column isolating switch, relates to the technical field of power systems, and solves the technical problem ofrecognizing the oil level of a transformer. The method comprises the steps that a rectangular opening and closing identification area is set in a monitoring image of the double-column type isolationswitch, two calibration areas A and B are defined in the opening and closing identification area, and a movable conductive tube and a static conductive tube of the double-column type isolation switchare both located in the calibration areas A; then, when the double-column isolating switch is closed, an image of an opening and closing identification area is intercepted as a reference image, gray processing is carried out on the reference image, and after fitting calculation, a calibration area A connection percentage value and a calibration area B background percentage value of the reference image are calculated; and identifying the real-time image in the opening and closing identification area by using the connection percentage value of the calibration area A and the background percentagevalue of the calibration area B of the reference image. The method provided by the invention is suitable for the substation configured with the high-voltage double-column isolating switch.
