There is no vehicle, no fault
Possible cause
Remedy
The 2D LiDAR sensors’ visual range has
been blocked by outside ambient
conditions, e.g., snow or dirt.
▸
Clear away anything that is blocking the 2D
LiDAR sensor’s measuring range.
▸
Check that the 2D LiDAR sensor’s visual range is
clear.
The IP addresses of the 2D LiDAR sensors
(e.g., those of the LMS Width and the LMS
Length) have been interchanged.
▸
Check the configuration.
Problems with length measurement/speed measurement
Possible cause
Remedy
Static objects are located in the LMS
Length’s field of view, e.g., concrete lane
barriers, guardrails, sections of the gantry
or a bridge, bumps in the surface of the
road, etc.
▸
Use the filtered raw data to check whether the
LMS Length’s visual range is clear (see chapter
8.3.1 Fault diagnosis in TEMS Manager
▸
Check the inspection window of the LMS Length
for contamination.
▸
Clean the inspection window of the 2D LiDAR
sensor.
Speed measurement with opposite sign
Possible cause
Remedy
The direction of travel was configured
incorrectly in TEMS Manager.
▸
Check the direction of travel for the lanes in
TEMS Manager. The configuration does not have
to be stopped for this.
Classification keeps delivering poor results (unclear 3D point clouds)
Possible cause
Remedy
The orientation of the 2D LiDAR sensors
was incorrectly rotated by 180° when
configuring it in TEMS Manager.
▸
Check the configuration.
The TIC501 mounting angle does not
correspond with correct alignment.
▸
Adjust the mounting angle in the configuration
until the point cloud of the vehicle is output in a
clean square shape.
The wrong classification system was
selected for the TIC501.
▸
Check the configuration. If the TIC501 is
mounted on the side of the lane, the
ECTN Side
classifier
basic category system must be
selected.
The IP addresses of the LMS Width and
the LMS Length have been interchanged.
▸
Check the configuration.
There is heavy contamination on the
inspection window of the 2D LiDAR
sensor.
▸
Clean the inspection window of the 2D LiDAR
sensor.
There are problems with length
measurement.
Static objects are located in the field of
view of the LMS Length, e.g., concrete
lane barriers, guardrails, sections of the
gantry or a bridge, or bumps in the
surface of the road.
▸
Use the
filtered
raw data to check whether the
visual range of the LMS Length is clear (see
chapter
8.3.1 Fault diagnosis in TEMS Manager
▸
Check the inspection window of the LMS Length
for contamination.
▸
Clean the inspection window of the 2D LiDAR
sensor.
