The BEA LZR-H100 is an impressive alternative to traditional induction loops. Designed for use with rising barriers, the LZR-H100 incorporates laser sensors to detect all types of vehicles and are used to open, secure and/or detect a presence.
Laser technology works according to the principle of time of flight. The sensor sends an intense light impulse in a defined direction and measures the time until the signal returns. As the speed of light is a constant value (approximately 300.000 km/s), this time is directly proportional to the distance between the sensor and the first object encountered by the light impulse.
As a result, and by sending multiple beams in multiple directions (2D or 3D), the sensor is capable of knowing the exact position of any object in its detection area at any given time. By analysing this information over a very short period of time, it is capable of determining the exact shape, speed, and direction of any object.
As you can see from the video, this solution provides four laser-based curtains, producing a three-dimensional detection zone for accurate object detection, including any type of vehicle or person for ultimate safety. The detection curtains are highly configurable and can be set up for activation and presence detection in vehicle sensing applications.
All types of vehicles are detected in the opening field: passenger cars, electrical vehicles, vehicles made of composite materials, trucks with trailers…You can also define the vehicle’s trajectory for targeted opening.
Pedestrian & cross-traffic filter
The barrier only opens when a vehicle is approaching. Pedestrians and parallell traffic in the opening field are screened.
