Research on monitoring system for foreign object intrusion in mountain railway
The railway in the southwestern mountainous area of China is prone to geological disasters such as landslides,deb-ris flow,and rockfall,which can lead to foreign object intrusion and pose a threat to train safety.Addressing the issues of false alarm,missed alarm,and low intelligence in the current monitoring system for foreign object intrusion in mountain railway,a monitoring system combining the vibration sensing,3D laser radar,and video multi-sensor fusion was proposed,and the low power wireless vibration sensing device and railway foreign object detection equipment were designed.The system was applied in multiple monitoring sites for foreign object intrusion in mountain railways.The results show that the monitoring system for foreign object intrusion in mountain railway can effectively reduce the false alarm rate and missed alarm rate,and improve the intelligence level of system.In the 2-year monitoring period from 2022 to 2024 of 18 monitoring sites for foreign object intru-sion in Chongqing-Huaihua Railway,there were no missed alarm,2 false alarms,and 1 rockfall impact protection net event was successfully captured,which effectively test the performance and reliability of the system.The research results can provide some reference for the development and research of monitoring system for foreign object intrusion in mountain railways,and ef-fectively ensure the safety of railway operation.
