Status Recognition of Isolator Technology Based on Substation Inspection Robot

摘要

This paper presents a method for checking the status of isolators, which is applied in the sequence control in smart substation based on mobile substation inspection robot (PowerRobot). It can recognize the status of an isolator through analyzing the features. The homography matrix can be obtained by using the SIFT feature between the template image and new acquired image. Then it gets the range of isolator, finally recognizing the status of isolator by image processing. The experiment results prove that the method could recognize the isolator status effectively. The substation realizes one key sequence control system through this technology based substation inspection robot.
