WORKSITE SAFETY DEVICE USING LIDAR

A perimeter safety device comprises a laser, detector, controller and an alarm. The laser emits optical laser radiation into a monitored zone. Laser radiation reflected from an object in the monitored zone is detected by the detector and a range to the object is determined by the controller. An alar...

Beschreibung
Zusammenfassung:	A perimeter safety device comprises a laser, detector, controller and an alarm. The laser emits optical laser radiation into a monitored zone. Laser radiation reflected from an object in the monitored zone is detected by the detector and a range to the object is determined by the controller. An alarm is activated if the object is determined to be in a location that is not authorized. The invention also reside in a network of perimeter safety devices that together define a monitored area formed of monitored zones. A central controller may define a pre-defined "safe" path through the monitored area.
