18 lugClassification with axles detection
The LSR-2001-AXIS sensor uses laser technology to detect vehicles and infrared photocells to detect axles. The emitted laser beam is used to scan on 1 plane on a 96 ° angle. Along the plane the sensor detects 274 points and is able to precisely identify the profile of the vehicle. The maximum sensing distance is 30 m. and the emitted beam is on the infrared field and is thus not visible.
The photocells couple consist of an emitter and a receiver and also work on the infrared range. They are able to accurately detect the presence of axles basing to the interruption of the emitted beam.
The laser sensor must be installed on a pole on the side of the lane about 5 meter height.
Being a laser scanner, the detector can measure the vehicle’s profiles and their presence. For this reasons it is very precise on classifying and counting vehicles even in “heavy” traffic conditions, stop & go and in queue presence.
The laser sensor information is combined, by the CPU
There are 2 versions of the LSR-2001-AXLES:
- LSR-2001-AXLES-1 with one couple of photocells
- LSR-2001-AXLES-2 with two couples of photocells
The main difference between the two versions stays in the fact that the version with two photocells LSR-2001-AXLES-2 is able to provide also the speed and the length of the vehicle. The photocells are installed on the ground at an height of about 5 cm. from the ground. The receiver shall be placed on the same side of the laser sensor while the transmitter on the opposite side, perpendicular to the lane.
