A Review of Research Intrusion Monitoring Technology for Railway Carrier Equipment

With China’s rail transit operating speed and transport loads continue to improve and the continuous expansion of the railway network scale, railway safety in the human defence, physical defence, technical defence “three in one” security system of the initial establishment of the railway perimeter security put forward higher requirements. Object detection and other detection technologies have received more and more attention, and the accuracy. The accuracy, reliability and robustness of the detection of technical defence means are the pain points and problems that need to be solved in the application of railway security engineering. The article firstly outlines the development history and technical process of railway perimeter intrusion object detection technology. Then it describes the research progress of image-based object detection, focusing on the RT-DETR real-time object detection algorithm based on Transformer. After that, the article compares the RT-DETR real-time target detection algorithm with YOLO series and traditional DETR in terms of improving accuracy and speed, and introduces image datasets and performance evaluation metrics. Finally, it analyses the main problems faced by railway perimeter intrusion object detection technology and points out to the future development direction of railway perimeter object detection technology.
