[0001] Embodiments of the present invention relate to a waste disposal vehicle and to a
method for controlling a lifting mechanism of a waste disposal vehicle. Further embodiments
refer to a lifting mechanism of a waste disposal vehicle and to a controller for the
lifting mechanism.
[0002] Conventional waste disposal providers use waste disposal vehicles, where the waste
Hopper, below referred to as container is positioned next to the lifting mechanism,
so that the lifting mechanism when being activated can lift the waste container from
a release position to a lifted position and further to an emptying position. Typically,
the waste disposal staff opens the lid of the waste container so as to check the content
of the waste container.
[0003] An example of a waste disposal vehicle is described in
WO 2019/183606 A1. When emptying the waste containers, there have already been tragic accidents in
which homeless people have suffered life-threatening injuries because they had laid
down in a waste container to sleep and were, for example, loaded with the gripper
arm of the waste disposal vehicle while disposing of the waste. It is very problematic
when the homeless have wrapped themselves in a foam mat or covered themselves with
cardboard.
[0004] The
WO 2021/255409 A1 describes a detector which is configured to be mounted to a container. The detector
has a housing and a mounting arrangement for mounting the housing to the container.
A sensor arrangement includes a sensor to monitor the container and to generate a
sensor output signal in response to a sense container event. A processor executes
a machine learning algorithm to determine a class of the sensed container event for
determining occupancy of the container from the sensor output signal, where the control
system is configured to provide an output based on the class of sensed container events
determined by the machine learning algorithm. A disadvantage of such a detector, which
is arranged on the waste container is that many such detectors are required, because
such a detector would have to be attached every container that could possibly serve
as accommodation as homeless people. Furthermore, it is possible that the detector
getting damaged parking or emptying the waste container, or it will be vandalized
by someone or the homeless person. Therefore, there is a need for an improved approach.
[0005] An objective of the present invention is a concept for avoiding that a human or animal
staying in a waste container is injured during the emptying.
[0006] The objective is solved by the subject-matter of the independent claims.
[0007] An embodiment provides a waste disposal vehicle, which comprises a lifting mechanism,
a sensor and a controller. The lifting mechanism is configured for lifting a waste
container. The sensor is configured to detect a signature, e.g., an infrared or thermal
signal on or within the waste container. The controller is configured to send a stop
command to the lifting mechanism if the signature complies with a characteristic signature,
wherein the characteristic signature is a signature of a human or an animal.
[0008] According to preferred embodiments, the sensor is an infrared or thermal sensor.
Consequently, the signature is an infrared/thermal signature, where the characteristic
signature comprises a characteristic infrared/thermal signature. According to further/general
embodiments, the sensor comprises a temperature sensor, e.g., a different kind of
temperature sensor. An infrared sensor may, for example, be realized by an infrared
camera or a thermopile array.
[0009] Embodiments of the present invention are based on the finding that it is possible
to detect homeless persons or any human-based objects contained within a waste container
during the lifting process by stopping the machinery before emptying the waste container
or a one or more equipment stages of emptying with the object of preventing a dangerous
situation. For this, a thermal imagery or thermal camera imagery may be used to identify
such objects. According to embodiments, this process can be supported by AI (artificial
intelligence). Embodiments of the present invention enable beneficially to determine
a human or animal within the waste container during the lifting procedure, such that
the lifting procedure can be stopped before the danger of injury the human or animal
exists.
[0010] According to an embodiment, the sensors attached to the lifting mechanism or a grip
arm, referred to as a lifting arm, of the lifting mechanism. Due to this arrangement,
it is possible to arrange the sensor more closely to the potential position of the
human or animal within the waste container. For example, the sensor may be directed
to the waste container gripped by the lifting mechanism, e.g., from the side. This
enables that the sensor is configured to determine a signature of the lower portion
or the middle portion of the waste container. Here, the sensor may be - according
to embodiments - activated during the lifting. For example, the controller is configured
to activate the sensor at a position before emptying or before reaching the emptying
position.
[0011] According to embodiments, the controller outputs a stop command so as to stop the
lifting. Preferably, the controller outputs a stop command so as to stop the lifting
before emptying or before the emptying position. This second possibility for outputting
the stop command is beneficially combinable with the above-discussed activation of
the sensor.
[0012] According to embodiments, the controller may be configured to differentiate between
at least two different sensitivity states, wherein the characteristic signature depends
on the sensitivity state. For example, in the lower sensitivity state, a signature
may be determined as characteristic signature, if the signature has a high amount
of specific characteristics. In a higher sensitivity state, the signature may be determined
as characteristic signature, even if just a few characteristics are determined. Characteristics
may be the temperature difference between the potential human characteristic and the
surrounding or may be the size of the potential human characteristic or the shape
of the potential human characteristic. According to embodiments, the selected sensitivity
state depends on the user input, a geographical classification of the current position,
a current position itself, and/or a value of a GNSS sensor of the waste disposal vehicle.
Background thereof is that in each city, there are certain areas where the probability
that a homeless person uses the waste container is higher or lower. According to embodiments,
a controller may comprise an artificial intelligence engine configured to determine
a sensitivity state and/or a geographical classification based on previous detections
of a human or an animal.
[0013] According to further embodiments, a controller is configured to control warning means,
like acoustic warning means. For example, the acoustic warning means are enabled dependent
on a sensitivity mode. According to an example, the acoustic warning signal may be
output when the sensitivity mode is high so as to wake up the homeless person sleeping
within the waste container. In this case, the human characteristic may be influenced
to a motion, which, vice versa, can be determined. Thus, according to embodiments,
the sensor is configured to determine a motion of the signature. Alternatively (or
additionally) optical warning means may be used as well. An optical warning could
be outside on a warning lamp or inside the cabin on a display.
[0014] Another embodiment provides a lifting mechanism for a waste disposal vehicle. The
lifting mechanism is configured for lifting the waste container and additionally comprises
the following elements:
- a sensor configured to detect a signature on or within the waste container; and
- a controller configured to send a stop command to the lifting mechanism, if the signature
complies with a characteristic signature, wherein the characteristic signature is
a signature of a human or an animal.
[0015] Another embodiment provides a controller for a lifting mechanism for a waste disposal
vehicle. The lifting mechanism is configured for lifting a waste container. The controller
comprises a sensor input for a sensor configured to detect a signature on or within
the waste container. The controller is further configured to send a stop command to
the lifting mechanism, if the signature complies with a characteristic signature,
where the characteristic signature is a signature of a human or an animal.
[0016] Another embodiment provides a method for controlling a lifting mechanism of a waste
disposal vehicle. The method comprises the following steps:
- lifting a waste container;
- detecting a signature on or within the waste container; and
- sending a stop command to the lifting mechanism if the signature complies with a characteristic
signature, wherein the characteristic signature is a signature of a human or an animal.
[0017] Of course, the lifting mechanism may be computer implemented. Thus, another embodiment
provides a computer program for performing, when running on a controller for a lifting
mechanism, the above-discussed method.
[0018] Embodiments of the present invention will subsequently be discussed referring to
the enclosed figures, wherein:
- Fig. 1
- shows a schematic representation of a waste disposal vehicle including a lifting mechanism
according to an embodiment;
- Fig. 2
- shows a lifting mechanism according to an embodiment including different positions
for a sensor; and
- Fig. 3
- shows a schematic flowchart illustrating a process for controlling a lifting mechanism
according to an embodiment.
[0019] Below, embodiment of the present invention will subsequently be discussed referred
to the enclosed figures, wherein identical reference numerals are provided to objects
having identical or similar functions, so that the description thereof is interchangeable
and mutually applicable.
[0020] Fig. 1 shows a waste disposal vehicle 10 comprising a waste container 12 and a loading
mechanism 20. The loading mechanism 20 can be arranged at different positions, since
a differentiation between front loaders, rear loaders, and side loaders is made. Furthermore,
it is differentiated between manual loaders, automated loaders, and semiautomatic
loaders. Especially for automated and semi-automated loaders, the side loader arrangement
is preferred, since the waste disposal vehicle 10 can drive along the walkway, stop
at the position of the waste container 30, and perform the loading and emptying procedure
automatically. For illustration reasons, the below discussion is focused on back loaders,
wherein teachings disclosed are applicable to other loader types.
[0021] The waste container 12 has an opening 12o, e.g., at the rear side of the vehicle
10 or at the top side of the waste container 12. Furthermore, the waste container
12 may have a garbage press 12p arranged inside the waste container 12 and configured
to compress the waste 32w inside the container 12.
[0022] At the backside of the vehicle 10, the lifting mechanism 20 is arranged. Same may
comprise a grip arm 22 which is configured to grip the waste container 30. Same is
lifted from a lower position to a lifted position and then transferred to emptying
position, where the waste container 30 is turned over, so that the content of the
waste container 30 is emptied through the opening 12o into the container 12.
[0023] As discussed above, often a waste container is used by a homeless person for sleeping.
Especially when the homeless person wraps themselves into a foam mat or cover themselves
with cardboard, they cannot be recognized by the waste disposal staff. To enable the
determination of homeless persons or in general persons/humans or even animals, a
sensor 40 is attached to the waste disposal vehicle 10 or especially to the lifting
mechanism 20. The controlling of the lifting mechanism 20 being influenced by the
sensor 40 will be discussed with respect to Fig. 2.
[0024] Fig. 2 shows a lifting mechanism 20, e.g., being attached to a waste container 12
of a waste disposal vehicle. For example, the lifting mechanism 20 comprises a rail,
along which a grip arm 20 can be moved from a lower position LP to a higher position
HP and emptying position EP. The grip arm 22 is configured to grip the container 30.
[0025] According to embodiments, the sensor 40 is attached to the gripping arm 22 or to
the lifting device 20 for the waste container 30 of the disposal vehicle 12. As it
is illustrated, the sensor 40' may additionally/alternatively be directed into the
opening 30o of the waste container 30.
[0026] Since above the structure of the lifting mechanism has been discussed, the functionality
will be discussed below. The container 30 is gripped by the gripping arm in the position
LP and then lifted along the rail 21 up to the position HP. From the position LP to
the position HP, the container 30 is still in the erected position, so that the container
opening 30o or the container lid 301 looks towards above. After position HP, the container
30 is transferred by the gripping arm 22 into the emptying position EP. Here, the
container 30 is turned around, such that the opening 30o substantially extends downwards,
so that the waste 32w falls due to gravity into the container 12. The emptying procedure
can be supported by shaking the container 30, so that the contents of the container
fall into the container 12. This procedure including gripping, lifting and emptying
is controlled by the controller 42. For example, the controller 42 receives a signal
to grip and lift the container 30 and controls the actuator of the lifting mechanism
20 to move the gripping arm 22 from the position LP to the position EP.
[0027] In case a human or an animal stays in the container 30 same is emptied into the container
12 together with the waste. This can cause an injury of the human or animal. Furthermore,
the press 12p can injure the human or animal.
[0028] To avoid this the human or animal must be detected before emptying. For this, a sensor
40 like an infrared sensor or - in general - thermal sensor can be attached to the
waste disposable vehicle 12. Preferably, the sensor 40 is attached to the lifting
mechanism 20 or the gripping arm 40 like in this case.
[0029] Here, the infrared sensor 40 is directed to the container 30, e.g., from the side,
so that a thermal pattern 34 or in general a characteristic signature can be determined.
Typically, the waste in a waste container 30 has an even temperature profile along
the surface of the container 30 or across the perspective of the infrared sensor 40.
In case, there is a locally increased temperature spot this can be determined by the
sensor 40. A human or animal has a characteristic signature. This signature may, for
example, be defined by size and/or shape and/or an absolute temperature and/or a temperature
profile along the geometry. Typically the temperature of the body and the head is
higher when compared to the temperature of the extremities. Thus, a temperature profile
for a human may be characterized by a relatively large temperature spot of approximately
above 30 degrees or above 35 degrees or above 36 degrees with upper and lower extremities
having a certain length and a reduced temperature in a range between 20 or 25 to 30
or 35 degrees. The controller 42 comprises such characteristics, so that same is enabled
to compare the detected signature with the characteristic signature which decide,
whether the probability that the determined signature 34 belongs to a human (complies
to a characteristic signature) is high or low.
[0030] According to embodiments, a controller may use a kind of threshold for the probability,
so a stop command can be sent by the controller 42 to stop the lifting procedure when
the probability is high enough. For example higher than 30 percent. Due to sending
the stop command the lifting procedure is stopped and especially stopped before reaching
the emptying position.
[0031] According to embodiments, the sensor 40 is activated before lifting or before reaching
the position HP or at least before reaching the position EP. For example, the sensor
40 may start to detect the characteristic 34 after gripping and during lifting before
the position HP or at the position HP.
[0032] According to embodiments the sensor 40 may be attached to the rail 21 or to the vehicle
10, so that it scans the container 40 during lifting subsequent to the opening of
the lid 30L. A possible position is marked by the reference numeral 40'.
[0033] According to embodiments, a sensor detecting the successful grip or a weighting unit
for determining the weight of the waste may be integrated into the grip arm 22. The
controller 42 may for example start the gripping procedure in response to a user command
or in response to a detection or optical detection of a container 30.
[0034] According to embodiments, the controller 42 and especially an artificial intelligence
engine of the controller 42 may evaluate the determination of a characteristic position
together with the position of the waste disposal vehicle. For this, a GPS sensor or
a comparable sensor may be used. By use of the positon information areas with high
probability of homeless persons may be differentiated from areas with low probability
of homeless persons. Dependent on the certain area/current position the sensitivity
of the sensor 40 may be adapted. As discusses above, a threshold may be used for determining
the probability of a characteristic signature. This threshold may be set to a lower
threshold, e.g. 30 percent for areas with high probability of homeless persons and
to a low value, e.g. 50 percent in regions with low probability of homeless persons.
This relationship may be determined by use of artificial intelligence.
[0035] Expressed in other words, this means that positions (GPS) can - according to embodiments
- be saved at which human objects (persons, such as homeless people) have already
been recognized in a waste container. This makes it possible to narrow down the areas
in which people often spend the night in containers (near train stations, parks, etc.).
This can serve as a warning for the driver or the operator or for increasing the reliability
or for adaption of probably thresholds.
[0036] According to further embodiments, artificial intelligence may be used for optimizing
the detection algorithm for detecting a characteristic signature. For example, by
giving a feedback that the detection was correct or wrong this detection algorithm
may be trained. Based on this machine learning system, it is possible to recognize
human objects (persons, such as homeless people) and in particular distinguish them
from rubbish objects. Furthermore, the machine learning system enables according to
embodiment to identify areas under which a homeless person might be (such areas covered
with a cardboard or foam mat). If it is the case that a human could not be clearly
identified, but identified with a probability, so that the waste disposal staff can
double-check the situation. Thus, in such a case it is according to embodiments possible
that the controller outputs an advice, e.g. to a driver or operator that this is where
the covered areas should be checked before starting or continuing the emptying process.
[0037] In case the position 22 for the sensor is used, the above-mentioned machine learning
system can be used to determine further thresholds. For example, it can be detected
whether the lid 201 of the waste container 20 is open or closed. If open, then start
the recognition. Otherwise, inform the driver and/or the operating person (acoustically
or via LED/display) that the lid of the container is to be opened. If no human object
was detected the container can then be further emptied in the empty position EP.
[0038] According to further embodiments, different kinds of sensor devices may be used.
For example, the above-discussed sensors 40/40' may be implemented as simple temperature
sensors or IO-camera (thermal imagery or thermal camera imagery). Alternatively a
simple camera may be used which performs image detection, so as to determine a person.
[0039] According to embodiments, one or more sensor devices or a combination of different
kinds of sensor devices may be used to improve the detection. For example, a measurement
of the outside temperature may be used to calibrate the thermal image, so that not
only an absolute value of the signature 34 is taken into account, but also a temperature
difference which might be high, when the surrounding temperature is low and which
might be low when the surrounding temperature is high. Especially by use of artificial
intelligence, this factor can be taken into account. A possibility to take this factor
into account is to vary the threshold for the probability of a detection, since a
low temperature difference between the surrounding and the assumed body temperature
of a person leads to the situation, that less characteristics of the signature 34
can be determined.
[0040] Another factor which can be taken into account is the motion of the person laying
within the container 30. According to embodiments an acoustic warning unit may be
used to wake up people sleeping in the waste container 30 if necessary and thus enable
(subsequent) detection by means of the sensor 40/40'.
[0041] According to embodiments the controller as described above can be part of the lifting
mechanism or can be part of the vehicle or implemented within the vehicle controller.
According to embodiments the controller has access to data gained by the vehicle,
e.g., to the GPS data. Furthermore, a connection to the vehicle on-board system or
to the board computer may be used, e.g., to output information regarding a detection
or regarding a probability or a hint for the staff, e.g., to open the lid 201. Furthermore,
an interface, e.g., a Wi-Fi interface or LTE/5G interface (a general communication
interface) may be used to get access to information stored in the cloud. This information
may include information on the previous detections assigned to respective positions.
Vice versa, information on detection may be stored within the cloud via this interface.
[0042] Fig. 3 shows a flow chart for the detection approach. The method 100 for controlling
the above-discussed lifting mechanism comprises the steps 110, 120 and 130. Here,
within the step 120 a differentiation between two different characteristics is made.
[0043] The step 110 refers to lifting the container 30. Here a sub step of opening the lid
30I may be performed. Subsequent to the lifting and/or opening of the waste container
30 the step 120a/120b is performed. Here, a signature 34a/b on or within the waste
container 30 is detected. In the step 120a and 120b a differentiation between two
different signatures 34a and 34b is made. The signature 34a is a signature clearly
indicating a human within the container 30. As can be seen, the signature 34a is above
35 °Celsius clearly differentiated from the surrounding having 16 °Celsius and having
the size of human. In contrast to this, the signature 34b comprises two portions both
having a sufficiently high temperature (35 °Celsius), wherein due to the separation
of the signature 34b into the two portions it could not be clearly decided, whether
this is a characteristic signature or not. However, based on the one characteristic,
that the temperature of 35 °Celsius being significantly higher than the temperature
of the surrounding (16 °Celsius) the probability of a detected human might be high,
e.g. higher than a preset threshold. Thus, subsequent to both steps 120a and 120b
the step 130 is performed, namely sending a stop command to the lifting mechanism,
if the signature complies with a characteristic signature if the signature 34a/34b
is comparable to a characteristic signature, wherein the characteristic signature
is a signature of a human or an animal.
[0044] In case no characteristic signature is determined (see step 130a) the step 130 is
not executed. Note the step 120 and especially step 130 is performed before emptying
the waste container, e.g. during the lifting, but before the position EP.
[0045] According to embodiments, a higher than Human Temperature signature alert may be
incorporated. Thus, the IR camera / sensor may be configured to distinctly determine
high temperatures. Background: An additional frequent subject is fire in the truck
this has been seen more and more commonly with the avid use of Lithium ion batteries
being incorrectly discarded into residual waste and not presented for recycling in
the correct way. This has seen increasing Truck fires and/or more seriously at the
disposal site once the waste is off loaded by the truck carrying it, there are systems
in the market to detect fire at these disposal sites but with this solution we could
also provide an additional benefit of further prevention of these Disposal site and
serious truck fires by providing an early warning system. For example, One or multiple
sensors may scan the containers in the lifting process, so as to capture the main
part of the container. Alternatively, it is possible to add more than one sensor to
more than one position to continuously scan the container and/or body of each Refuse
truck type i.e. rear, side front loader.
[0046] According to embodiments, this could also provide GPS position for where the waste
was collected from if detected in the waste container during emptying and/or where
the truck is should it detect after an emptying or while the truck is in motion to
alert the driver and the office of a potential fire so it can be dealt with before
the truck is consumed.
[0047] According to embodiments, it is possible to add further sensors with flush fitting
sensors into a boss added to the truck body at intervals to monitor the internal body
temperature of the waste.

[0049] Depending on certain implementation requirements, embodiments of the invention can

a digital storage medium, for example a floppy disk, a DVD, a Blu-Ray, a CD, a ROM,
