Operating principle
Fig. 6:
Monitoring principle
•
One or two 2D LiDAR sensors mounted on the industrial truck continuously monitor the
area behind the vehicle when the reverse gear is activated.
•
Depending on the mounting position, monitoring of the side area is also possible.
•
With the factory setting, the monitored area scanned by the 2D LiDAR sensor is divided
into the two
Warning
and
Stop
monitoring fields.
•
The size and geometry of the monitoring fields can vary and must be parameterized
correspondingly during commissioning.
•
Each monitoring field is assigned to a switching output of the 2D LiDAR sensor.
•
When an object is detected in a monitoring field, the switching signal is passed on to
the control unit.
•
The control unit processes the incoming signals from the 2D LiDAR sensor and signals
corresponding
results such as “object detection within the warning field” or “object
detecti
on within the stopping field” to the optical and acoustic signa
ling devices.
NOTE!
•
To avoid false alarms, the signals from the 2D LiDAR sensor are only taken into
account when the vehicle is
reversing (
with
reverse gear activated
).
•
If an object is detected in
warning field 2
(=stopping field), the system does not stop
the vehicle.
•
The driver only receives an acoustic and visual signal to initiate braking of the vehicle.
