RAM111

Description

RAM111 is the highest-level sensor for overheight vehicle detection, based on a laser scanner and a double-beam laser.

The RAM111 emitted light is reflected so that it can be recognized by the receiver, which filters the environmental light noises.

The laser scanner is very accurate in measuring the height and detecting the presence of a vehicle, while the double beam laser has a very high frequency and a narrow angle, allowing the detection of objects of small dimensions even at a distance of 20 m.

An internal CPU works in real time combining the data of both lasers and thus providing very accurate data. The algorithms are designed to detect small objects over the allowed height but to trigger the alarm only when the presence of a vehicle is detected, reducing the false alarm rate.

Moreover, the system can also inform which lane the vehicle is traveling in. RAM111, installed on the side of the road, can detect overheight vehicles in three lanes.

Compared to systems based on photocells with transmitter and receiver, the RAM series has the advantage of easy installation, as they are placed on the road’s side and don’t need to collimate transmitter and receiver.

It is also possible to combine the laser detection with a variable message sign (VMS) to alert the driver about the potential danger. When an overheight vehicle is detected, RAM111 provides alarms in different ways: relay contact, digital output and software event (protocol).
