Tracking Position and Status of Electric Control Switches Based on YOLO Detector

摘要

Tracking position and status of switches of electric control cabinets is the key to automatic polling and management systems for intelligent substation. It is a typical task of multi-target image detection and recognition. In this paper, we present an end-to-end switch position detection and state recognition system based on YOLO detector that can detect and recognize multiple targets in a single frame at one time. A four-category network based on YOLOv3-tiny is designed and optimized for real-time detection, then logistic regression is used to predict the probability of status of switches, and then an algorithm based on the prior information of the cabinet is developed to remove duplicate targets. Finally, the detected switches are sorted and numbered to compare with the information in the database. Experiments are reported to verify the proposed system.
