Monitoring tunnel portals

         Many trains travel through tunnels on a daily basis during normal operation. The AOS LiDAR object detection system monitors the area in front of the tunnel portal using 2D LiDAR sensors. When an object such as a person or an animal approaches the tunnel, this is detected and an alarm is issued. Trains are recognized as such and can travel through the tunnel without triggering an alarm. This avoids collisions and prevents vandalism or terror attacks.

  • Non-contact detection due to LiDAR technology
  • Adjustable, application-specific monitoring areas
  • Automated self-test cycles
  • Customized control configurations
  • Easy implementation of new functions
  • Optional gateways for remote diagnosis or data analyses
