Abstract:With the demand for quality improvement and efficiency enhancement, the intelligent inspection service of substations is rapidly evolving. In the intelligent inspection system of substations, robots undertake daily and emergency inspection tasks and need to mark inspection points. The traditional online point marking method is inefficient and has many shortcomings. In response to the problems of traditional point marking, this paper proposes a robot point marking method based on virtual scene, completing point marking and verification in a virtual scene, which is not affected by work tickets and weather conditions, effectively improving the operation and maintenance efficiency of inspection robots. The successful application of this method in a substation proves the efficiency of it, meeting the demand for quality improvement and efficiency enhancement of intelligent operation and maintenance.
