【Abstract】 In this paper, a comprehensive review on the research status of intrusion detection, categories of abnormal objects and common consequence caused by abnormal objects on railways are outlined. Related work of intrusion detection methods, such as grid detection, fiber grating detection, video detection, radar detection, ultrasonic detection and infrared barrier method were summarized and reviewed. The application scenarios, detection performance, advantages and limitations of state-of-art intrusion detection methods were summarized. At last, the future direction of railway intrusion detection technology was discussed.更多还原
