Design and application of real-time monitoring system for service status of continuously welded turnout on the high-speed railway bridge

Wireless sensing in high-speed railway turnouts with battery-free materials and devices

“…Real-time data of service status indicators were acquired using fiber grating and video perception technologies from the perspectives of video perception technologies. A real-time monitoring system for the service status of the bridge’s continuously welded turnouts has been in place for more than four years, effectively maintaining railway safety and security 18 A computer vision approach for detecting wear on railway automated switch stationary contacts was presented, which computes average pixel distance in wear zones and rescales to real-world level using image calibration tools. 19 Furthermore, an image sensor-based detector was constructed, and an automated technique was presented to assess the size of the switch gap using the detector’s pictures.…”
