2D LiDAR sensors
The 2D LiDAR sensor records the contour of the passing vehicle. To do this, it establishes
a measuring range and scans the vehicle using a non-contact time-of-flight process.
The laser beam is emitted through the inspection window. The scan plane position of the
LMS511 is indicated by a housing marking next to the inspection window (see the circle in
the figure below).
In the TIC102, the 2D LiDAR sensors are installed as a fixed component in the housing.
The laser is beamed through special output apertures in the housing.

The 2D LiDAR sensors automatically measure contamination on the inspection window.
The level of contamination is displayed directly on the device or displayed via the Traffic
Controller and/or transmitted to the downstream customer system.
For detailed information about the operating principle of the 2D LiDAR sensors, please
refer to the operating instructions for the LMS111 and LMS511 product families.
Traffic Controller
The Traffic Controller uses the installed profiling software to calculate the vehicle
dimensions using the vehicle contour, the vehicle class and other data.
At the same time, the Traffic Controller acts as the central control unit for the profiling
system. Using its TCP/IP Ethernet interface, it constantly provides the downstream
systems with all system data, the measuring points, measurement results, and system
messages.
The TCP/IP interface is also used for set-up, calibration, and fault analysis with the aid of
tools.
