LaserProf

LaserProf is a portable system designed for road profiling measurements with no need for permanent installations. The system can be mounted on the trailer hook on a vehicle. The LaserProf is a flexible, fast, and reliable precision tool.

LaserProf is fitted in a standard suitcase, and it can be mounted in a few minutes on-site. The high maximum speed capacity allows you to perform measurements while the road is open to the public and with the pace of undisturbed traffic.

Measuring principle

LaserProf is fitted in a standard suitcase, and it can be mounted in a few minutes on-site. The high maximum speed capacity allows you to perform measurements while the road is open to the public and with the pace of undisturbed traffic.

LaserProf is utilising the latest FPGA technology (Field Programmable Gate Array). The FPGA runs at 50 MHz and collect data from the different sensors. The data is then organized by the FPGA and transmitted to a computer using a normal ethernet connection. An 100 kHz 16 bit A/D converter and 1 g bias circuitry is integrated to handle analog input from accelerometers.

The electronics is integrated on one board. The system can be powered from both 12V and 24V vehicle systems. A built in DC/DC converter steps up the voltage to charge two 12 volt rechargeable batteries providing power supply stabilisation (UPS).

Typical sensors for the LaserProf configuration:

• Digital Selcom laser profile sensors. (Update frequency from 16 kHz to 64 kHz)
• Odometer implemented with an encoder 1 pulse per 0.1 mm distance traveled
• GPS

Collected data can be real time or post mission resampled into intervals chosen by the user. For a standard 16 kHz profile sensor typical resampling intervals is 25 mm - 100 mm. For a 64 kHz texture sensor typical resampling intervals is 0.5 mm - 2.5 mm

Results like IRI and MPD can be presented in a number of formats in intervals chosen by the user, typical 10 m - 25 m.

A Laptop is connected to the control box via the ethernet port. The laptop stores data and calculates certain results real-time.

The odometer is magnetically mounted on the wheel of a vehicle. This generates high precision distance measurements.
One sensor boxe is mounted using the flexible mounting kit: Either on the trailer hook on a vehicle, or with vacuum cups on any glass or painted surface of the vehicle.
Two sensor boxes are mounted using the flexible mounting kit: Either on the trailer hook on a vehicle, or with vacuum cups on any glass or painted surface of the vehicle.
The LaserProf control box is connected to the electrical system of the vehicle, either directly to the battery or in the cigarette lighter socket. The laptop is connected to the control box via the Ethernet port. The control box combines and collects sensor information from odometer, lasers and accelerometer. The laptop stores data and calculates certain results real-time.
