In this case, the two ultrasonic sensors underneath the bin deflectors form the upper detection plane, while the three
sensors are mounted underneath the lifters. These are located here in the driving-off position. All the sensors are
installed in an upright position.
Generally speaking, the following installation rules of thumb have proved effective:
„
The ultrasonic sensors should be installed wherever possible at the rear end of all the attached mechanisms so
that no parts of them protrude into the measuring area of the sensors.
„
The best solution has often proved to be to install a sensor directly underneath each bin deflector (assuming that
the lifting and tipping mechanism is fitted with such deflectors). This location is not always suitable, however.
„
In the case of systems that just have a loading position (i.e. without a driving-off position), it is often only possible to
install two sensors on one main level.
„
If sensors are only installed on one main level, they should be mounted wherever possible at a height of between
50 and 90 cm above the road surface.
„
The distance between the two (outer) sensors on the main level should be at least 1.50 metres.
„
In the case of systems with a driving-off position, an additional level with two to three further sensors can frequently
be realised.
„
Where sensors have been installed on two planes, the bottom edge of the sensors on the lower plane should be at
least 40 cm above the road surface. Otherwise, ramps or curbs will be mistakenly detected as being objects behind
the vehicle when it drives over them.
„
In the case of a lower additional level, the outer 15° sensors should be mounted within the treads for the refuse
collectors (if present) so that they are not in the measuring area.
„
The distance between the two (outer) sensors of a lower additional level should be at least 1.20 metres.
„
Here is a general note on the size and form of the measuring areas of the ultrasonic sensors: The club-shaped
measuring area of an upright installed sensor is approx. 1.20 metre wide and approx. 20 cm high (namely the
installation height of the /- 10 cm) at a distance of 1 metre.
