Passive Warning System by Ballast Tools Equipment

The BTE BallastVisionTM Short Range Passive Mode Warning System is designed to detect objects and alert equipment operators of objects and personnel within the specified detection zones.

BallastVision Cameras detect objects in the predetermined detection zones. The system can detect objects within a range of 95 feet for reflective objects and does not require personnel to carry a special token or device with them.

SEE IT IN ACTION

Protecting personnel working in and around roadway work equipment has long been a top priority throughout the railway industry. While on-track safety has continued to improve steadily there is still a need to apply new technology to help eliminate on-track incidents – especially in the “work zone.”BTE was recently approached by a Class 1 railroad to develop new technology to alert work equipment operators and on-track personnel of one another’s presence.

BENEFITS

Alerts on-track workers to approaching machines
Alerts machine operators of objects and workers in close
proximity to the machine
Real-time, live view cameras allow operators to see objects and personnel
3D detection of scenes and objects
Suited for use in mobile machines
IP67 rated for operation in harsh industrial environments
High protection rating for the requirements of harsh industrial environments
Reliable distance measurement
Indication of warnings and obstacles in the live view

Applications

Vehicle to track worker advance warning
Vehicle to vehicle collision avoidance

Coming and Going

The system utilizes forward and rear facing cameras and an in-cab display equipped with warning lights and an audible alarm.

THE SOLUTION

BallastVision is a LIDAR based system designed to detect objects and alert equipment operators of objects and personnel within the specified detection zones. The system utilizes forward and rear facing cameras and an in-cab display equipped with warning lights and an audible alarm. BallastVision also utilizes an exterior light and alarm beacons to alert personnel working around the machine. Detection zones are configurable in 4 directions: distance, minimum height, maximum height and width of detection areas. BallastVision can detect objects within a range of 95 feet for reflective objects and 30 feet for non-reflective objects and does not require personnel to carry a special token or device with them.
