The present invention relates to an automatic data acquisition system, in particular a system for acquiriny the data of refuse, comprising a receptacle and a collection container serving to empty the receptacle.
Since decades, data acquisition systems of the kind under discussion have been known from practice in the most different versions. Such systems are used all over where any kind of solids or liquids are first collected in receptacles and subsequently removed in larger receptacles, such as collection containers. It should be emphasized already at this point that the contents collected in the receptacles or collection containers may include any kind of liguids, solids, i.e., objects or the like which can be discharged on the one hand, and be collected in any form on the other hand.
Thus, for example, it is conceivable that with the above-described data acquisition system, grapes or the like are first collected by individuals into receptacles and subsequently, when the receptacle iS filled, discharged into a collection container for removal. The range of application of such systems is by no means limited to special uses.
In the following, the known data acquisition system under discussion will be described in more detail with reference to the collection of refuse only by way of example.
The removal of refuse is currently one of our most serious environmental problems in general. Almost everything that is in these days purchased or consumed, is expensively packaged, so that already within the scope of daily consumption a considerable quantity of discarded packing material accumulates. Overflowing 2 0 ~
refuse containers and overfilled landfills are the consequence.
It is now intended to encourage private households more and more to separate the daily accumulating refuse by materials, so as to enable an environment protecting recycling of the raw materials.
However, apart from the environment-conscious mental attitude which underlies such a behavior, there are currently no incentives for the population to reduce substantially the quantity of the refuse to be collected from households and businesses. While the utilization of a compost pile or a separate delivery of glass, metal, or paper reduce already the amount of refuse accumulating altogether in particularly environment-conscious households, it will however be necessary to strive for a drastic reduction of refuse by the entire population, i.e., in all households, as a result of continuously increasing costs for removal and storage.
A possibility of fighting the increasing buildup of refuse would be the enactment of laws and/or ordinances. This, however, would take time and would certainly meet with considerable political resistance.
Nuch more suitable in this instance appear to be primarily monetary incentives to reduce the amount of refuse which is separated by raw materials or can be separated, and need to be removed as a whole. However, the existing fee system of communities is not very .
suitable to this end. The customer, i.e., the household, pays presently a lump sum per refuse container, or large receptacle, no matter whether the refuse container or the large receptacle is empty, half full or even overfilled. No incentive exists to the end of not totally filling a refuse container which is emptied for example every week.

The less refuse needs to be picked up, for example, every week, the less the customer would have :..
to pay for the removal. Such a regulation would give rise to motivate the population in any event as regards money to reduce the quantity which cannot be turned over to recycling, which would certainly be effective up to and including a "package-conscious" buying behavior of the consumers.
It is therefore one object of the present invention to configure and further develop a data acquisition system of the initially described kind, in particular a data acquisition system within the ~cope of removing refuse, such that it is possible to pick up the collected material of any kind while registering the weight of the collected material, which can be associated to the collector. Another object of the invention is to describe a method of automatically acquiring data of refuse, which utilizes the automatic data acquisition system in accordance with the invention.
The automatic data acquisition system of the present invention, which solves the aforesaid problem, is described by the characteristic features of clai~ 1.
Accordingly, an automatic data acquisition system comprising a receptacle and a collection container serving to empty the receptacle, in particular a system for acquiring data of refuse, is designed and constructed such that an identification feature is associated to the receptacle, and that the collection container is provided with a reader to recognize or read the identification feature, a weighing device for weighing the receptacle before and after emptying, and a computer with a memory unit for storing the weight difference of the receptacle before and after its emptying wtih association of the identification feature.

The present invention has first recognized the necessity to gather data of collected material of any kind while considering the weight of the collected ~' ,. - .. ~ : - . . . . , . . , .. , : . ... , .: . . -. : ~
4 2~8'~2 material, and to remove same. It has further been recognized that it is necessary to this end to associate the determined weight to each collector, so as to obtain, for example in the case of household refuse a bill concerning the collection of the refuse, or in the case of picking and harvesting grapes, a performance-dependent basis for computing the wages of the harvesters. In accordance with the invention, this association is possible in that on the one hand an identification feature is associated to the receptacle of the collector, for example, the refuse container.
On the other hand, a reader is associated to the collection container for recognizing or reading the identification feature. This enables already the identification and association. Finally, a weighing device for weighing the receptacle before and after emptying, as well as a computer with a memory unit for storing the weight difference of the receptacle before and after its emptying are needed, so that the weight can be stored or further processed with association of the identification feature.
In a simple embodiment of the data acguisition system in accordance with the invention, the identification feature is a readable identification number. The reader associated to the collection container operates by light optics. The identification feature or the readable identification number could be glued, or painted or sprayed onto the receptacle.
Likewise however, the identification feature could be applied to or glued on the receptacle in the form of a bar code. This bar code would then have to be read by the operating personnel with a reader in the form of a bar code pin reader associated with the collection container or computer respectively. Aside from the known bar codes, it would be possible to use any coding which is readable or unreadable by a human ,. . .
:.
2 ~ i 2 being, and suitable for a light-optical, automatic reading by means of a corresponding reader.
As regards an acquisition of data suitable for electronic data processing, it will be especially advantageous to provide the identification feature encoded in a code carrier. The latter could be releasably attached to the receptacle. To avoid that the code carrier associated to the respective receptacle is easily manipulatable by the collector, is t advantageous that the code carrier can be removed from the receptacle only by means of a special tool. As a - further protection against unlawful manipulations, the code carrier could be lead-sealed to the receptacle.
To reduce the cost incurred with securing the code carrier against manipulations or even its removal or exchange, the code carrier could be attached to the receptacle stationarily, i.e. not removably. In an advantageous manner, this could be accomplished in that the code carrier is made integral with the receptacle.
In such an instance, the code carrier with an unchangeable identification feature would be associated to or "incorporated" in the receptacle, for example, already during its manu~acture.
Likewise, the code carrier could be integrated in or attached to a handle of the receptacle. An advantage of this arrangement of the code carrier can be seen, among other things, in that the handle of the receptacle is always easily i accessible, and thus likewise the code carrier which is attached thereto or provided thereon for the reader.
In particular in the case of a subsequent, i.e. not integrated arrangement of the code carrier, it is advisable to protect same against a harmful atmosphere or dirt as well as excessive mechanical stress. To this end, it will be advantageous to seal the code carrier in a plastic housing, which would naturally have to be transparent, when an ~.
2 ~
identification feature to be read by light optics is used.
In particular with regard to an unobstructed data transmission and continuing data processing, the code carrier itself could be made in an especially advantageous manner as a wireless operating, electronic code carrier. In this instance, the code carrier would contain the identification feature in an encoded, unchangeable form, which is read by the reader in noncontacting manner.
As regards the supply of energy to such a code carrier, it would be of advantage, in particular with respect to the space necessary for installation, if the code carrier operated without its own, i.e.
internal supply of energy. To realize this, the code carrier could receive the necessary energy during the reading by induction via the reader, for example, by -means of high-frequency waves. However, it should also be ensured that the identification feature remains -~
permanently stored in the code carrier also over a `
longer period of time without an inductive supply of energy via the reader.
In a particularly advantageous manner, the code carrier is provided with a miniaturized sender, and the collection container or the reader has a miniaturized receiver. In this instance, the identification feature will be transmitted, when the reader supplies energy by induction, to the reader, and received by the receiver provided therein. Such a combination of sender and receiver would make it difficult to access or manipulate the code carrier without authorization.
To cope with any winter and summer temperatures, the code carrier should consist of such ~-materials that it operates without problems at temperatures ranging from -30C to +75C.

, - ' , . , , . '' .' ' ., ~ . , . . ` ~ ' ' . .; ' 2~''&~2 In order to enable the operating personnel of the automatic data acquisition system in accordance with the invention to recognize the identification feature without technical aids, in particular for a proper return of the receptacle, it will be of great advantage, when for example the identification feature is arranged in addition on the code carrier or on the receptacle in a visible, i.e. readable form.
This arrangement will also be of great `r, importance, especially when the code carrier on the receptacle serving as a wireless data storage operates improperly or not at all. In such an event, it should be possible to manually input the number or the identification feature of the receptacle to be emptied.
The operator can read a glued on identification ` feature, for example a number, and communicate same by means of an intercom system to an operator of the memory unit. If the system of the present invention is used on a refuse collection truck, a worker would read at a failure of the code carrier the respective number and communicate same via an intercom system to the driver in the cab. The driver would then input this number via a key pad for further processing.
A further characteristic resides in that the intercom system could be automatically connected at a failure of the code carrier. Since the refuse collector wears thick working gloves in particular in winter, the operation of the key pad by the driver is especially advantageous inasmuch as the latter is anyway idle while the refuse container is emptied.
Within the scope of one aforesaid, especially preferred application of the data acquisition system of the present invention, the concern is the removal of refuse. The receptacle in this instance is a refuse container. The collection container would then be associated with in known manner with a refuse collection truck. The operating personnel of the .
. .
2 Q ~ 2 refuse collection truck would empty the refuse container or the like in known manner into the refuse collection truck. This procedure remains also unchanged in accordance with the teaching of the present invention.
To raise the refuse container, the collection truck is provided in known manner with a lifting mechanism. To determine the weight of the full and the emptied refuse container, the lifting mechanism itself is provided with power sensors, so that the weight of ., the full refuse container and the emptied container can be determined in a simple manner respectively when the refuse container is lifted and set down.
To ~e able to dynamically weigh in a particularly advantageous manner, it is necessary to consider the acceleration of the earth or respectively the mass inertia when lifting the refuse container, so as to avoid a false determination of the weight.
Otherwise, it would be necessary to weigh in an operating phase, in which neither an increase nor a decrease of speed occurs, i.e. in which neither positive nor negative accelerations occur. To realize such a dynamic determination of weight, while eliminating the mass inertia or respectively the acceleration of the earth, at least one acceleration sensor is provided in a particularly advantageous manner, which is preferably associated with the lifting ;
mechanism. The acceleration sensor picks up the speed of the refuse container and corrects accordingly the result of the weighing while considering the negative or positive acceleration. In this instance, for example a commercially available acceleration pickup or a standard force gauge is used as a sensor. Besides the acceleration sensor, it is advantageous to provide likewise an inclination sensor. While the weight is determined, the following occurs:
'f -, :.
'' ' .
.. ..
., "' 9 2 ~ 2 A known weight (dead load) undergoes the same acceleration as the receptacle to be emptied with the refuse contained therein. When now an acceleration occurs as the refuse container is lifted, the weight of the weighing container with the refuse therein increases percentagewise at the same ratio as the weight of the dead load at the reference sensor. This allows to compensate for the change in weight of the refuse in the receptacle with unknown weight, which is prodl~ced by negative or positive acceleration.
Likewise, the method under discussion allows to advantageously compensate for any factors which influence the weight determination, for example, also vibrations of the vehicle. Naturally, the application of the above-described compensation of the dynamic when determining the weight is not limited to the case of refuse collection.
As the weight is determined during th~
lifting operation, however, the problem arises that any ballast adhering to the refuse container, such as for example snow in winter, is likewise weighed. When the refuse container is emptied, this ballast drops, i.e., it is added to the weight of the material to be discharged. Accordingly, the customer would pay for the snow which dropped during the emptying.
.. . .
It is possible to eliminate the foregoing problem in that an intermediate container is provided.
i In this instance, the contents of the refuse containar ~1) are first emptied into the intermediate container, i.e., they are not weighed during the actual lifting operation. The intermediate container with the discharged material to be carried away is subsequently weighed with any ballast removed. Moreover, this further development of the teaching in accordance with the invention has the great advantage that in the case of multichamber refuse containers, it i5 possible to weigh sorted bulk material separately. -~ 2~g~2 In a particularly advantageous manner, a refuse discharge computer is associated with the collection container or respectively the refuse collection truck. The signal of the power sensor, which represents the weight of the full and the emptied refuse container, is input, preferably via a measuring amplifier, in this discharge computer which again controls the lifting mechanism.
With respect to a further processing of the data, the measuring amplifier is provided with a programmable intelligence in the meaning of a computer or microprocessor. The microprocessor of the measuring amplifier linearizes the measuring signals, and performs, if need be, a temperature compensation and an error correction.
To ensure a csrtain operational ease, it is of advantage, when the discharge computer is provided with an LCD and a key pad. The LCD could, for example, indicate the momentary operating mode of the discharge :
computer, but liXewise the identification feature of the refuse container which is just being emptied. The ;
key pad would allow to manually input data or commands.
Such an input would be necessary, for example when, for any reasons whatsoever, it would no longer be possible to electronically read the identification feature. In this instance, the operating personnel would have to read the identification feature or the identification number and input same manually via the key pad. Absent ~ -a recognition of the identification feature, it would also be conceivable to input the name of the customer, to which the computer would automatically associate the correctly stored identification feature.
The discharge computer transmits in an advantageous manner the measured signals to an onboard computer in the cab of the refuse collection truck.
The onboard computer is provided with a microprocessor and, preferably, with an internal c~ock. Furthermore, ' .
', : - ... ' , . ,~ , ~ ' '` ' ' " . ` :
2 ~ 3 '~ 2 , . 11 the onboard computer may be integrated in the data acquisition system such that it coordinates the discharge of the refuse and the discharge computer.
If need be, a record printer is connected to the onboard computer. This record printer serves on the one hand to immediately prepare a trip report of the refuse collection truck. On the other hand, it can ; secure the determined data in written form for the event that all electronically stored data are lost as a result of a system error.
; As regards the data to be acquired as a whole, it will be of advantage, when besides the weight and the identification feature of the refuse container, the vehicle number of the refuse collection truck and .
the time of the emptying are recorded and stored in the onboard computer. This serves in particular to document the service rendered as a result of emptying the refuse containers. Moreover, any desired information to be predetermined by the operating personnel may be input, and associated with the identification feature.
With respect to securing and transmitting the data, it is particularly advantageous when the onboard computer is provided with mobile storage cards as an output medium. These storage cards will then serve at the same time as input medium for a preferably stationary central computer.
For a simpler handling, the mobile storage cards could be of the size of check cards. Likewise, it would be conceivable that the storage cards have ~heir own energy supply in the form of a miniature battery. Likewise, as regards the securing of data, the storage card could be protected in a particularly advantageous manner by a shielding against overvoltage and voltage discharge.
While foregoing a further data transmission by means of storage cards, the data gathered by means .
: .
of the data acquisition system of the present invention and, if need be, stored in the on board computer could in a particularly elegant manner be radioed directly to a preferably stationary processing center with a central computer. Likewise, it is possible to communicate these data by means of infrared light directly to the preferably stationary processing center, it being necessary in this instance that the latter be in direct vicinity.
In the event of transmitting the data by means of storage cards, the central computer would have to be provided with a card reader for reading the mobile storage cards. To prepare invoices or statistics, graphics or the like, it would also be possible to provide in addition a printer for printing out the data prepared by the central computer. , It is also possible to design and construct the lifting mechanism for emptying two receptacles or refuse containers, i.e. for a double discharge. In this instance, it is of particular advantage with -regard to an always required weighing accuracy, when the control for the lifting mechanism, preferably designed as a hydraulic control, is linked with the -onboard computer. As a result, a synchronization of the weighing and the control of the hydraulic is realized, so that the weighing device operates only in the measuring phase and not during the lifting operation-Within the scope of a further, advantageous embodiment, the receptacle or refuse container may have at least two chambers separated from one another, which is to be preferred especially from ecological viewpoints. In the chambers, the refuse is separated by kinds, and the collection container receives the sorted refuse accordingly separated.
To be able to check reliably the contents of a receptacle or the receptacles, in a particularly ;
:, : .
2 ~ g ~
advantageous manner, the contents of a receptacle or the receptacles to be emptied are detected via a camera system which is preferably associated with the lifting mechanism. In its place, or in addition, the contents of the receptacle may also be detected, as regards metal, via a metal sensor which is preferably associated with the lifting mechanism. Likewise, it is possible to arrange chemical or spectroanalytical sensors for the detection of paints, varnish and other chemicals.
To avoid that hazardous contents of the receptacle are not mixed with the so-called residual refuse in the collection container, a special device is provided for sorting out or separating special refuse that is detected.
Furthermore, it would also be possible to detect the contents of the receptacle with respect to its volume, preferably by means of level sensors. The latter could operate by induction, capacitance, or by the eddy-current principle. Level sensors operating by capacitance could advantageously be constructed as a capacitance strip. However, the level sensors could operate liXewise by light optics.
In the case of a receptacle having at least two chambers, the respective chambers should be detected each individually.
Furthermore, it will be of special advantage, when the components of the data acquisition system are interconnected, galvanically decoupled, via a preferably serial field bus system.
Finally, the code carrier could be provided, besides the identification eature, with a read-write memory. Accordingly, the reader would be constructed as a read-write device. When the receptacle is emptied, all detected data could then be written via the read-write device into the memory, so that always cumulated data are associated to the receptacle, which ' :
~, 2~8~2 may be requested by the owner of the receptacle for a check, if need be.
The portion of the problem underlying the teaching of the present invention, which relates to a method, is solved in that a method of automatically acquiring data of refuse comprises the following steps:
before the start of the work or trip, a mobile storage card is inserted into the onboard computer of the refuse collection truck. As usual, the refuse containers are emptied, with the following occurring:
before or during the lifting of the refuse container, a noncontacting reader reads the identification feature.
The latter is transmitted via a discharge computer to the onboard computer where it is stored. Subsequently the weight of the full refuse container is determined via power sensors provided in the lifting mechanism, and likewise transmitted, via the discharge computer to the onboard computer. The emptied refuse container is lowered in the usual manner, with the weight of the emptied refuse container being determined via the power sensors provided in the lifting mechanism, and likewise transmitted via the discharge computer to the onboard computer. The weight difference, i.e., the weight of the emptied refuse, is stored in the onboard computer or on the mobile storage card and associated to the pertinent, previously read identification feature, it being likewise possible to associate to the identification feature, if need be, further data, such as for example, time, vehicle number, or the like. If desired, a record printer will print out the determined and associated data. At the end of the trip, the mobile storage card is removed from the onboard computer and delivered to the processing center. The storage card or the data stored on the storage card are read via a card reader of the central computer and evaluated by the latter. The evaluation serves~ for example, to prepare invoices, statistics, and other ' ~i :

evaluations by means of printers, plotters, or the like.
There are two different possibilities of advantageously configuring and further developing the subject matter of the present invention. To this end, reference is made on the one hand to dependent claims 2-49 or respectively 51, and on the other hand to the description of an embodiment of the subject matter with reference to the drawing.

2 ~ 2 As further shown in Figures 1 and 3, the discharge computer 10 transmits the measuring signals to an onboard compu~er 15 preferably arranged in the cab 14 of the refuse collection truck 2.

A record printer not shown in the Figures can be connected to the onboard computer 15.
As shown in the schematic illustration of Figure 5, it is also possible to acquire, besides the weight and the identification feature of refuse container 1, the vehicle number of refuse collection truck 2 and the time of the emptying, and to store same in onboard computer 15.
Moreover, it is possible to store in onboard computer 15 any desired information which can be input by the operating personnel with association to the identification feature ~.
Indicated in Figures 1 and 4 is that the onboard computer 15 uses mobile storage cards 17 as an output medium. ~he storage cards 17 serve as input medium for a preferably stationary central co~puter 18 which is qenerally accommodated in a municipal or local administration building.

Naturally, the data prepared in the central computer 18 may also be used for further preparation of information, so that it is possible to generate likewise extensive, informative customer data banks and statistics besides invoicing or collecting late payment~.
Finally, it should be emphasized that the teaching of the present invention is merely explained by the above-described embodiment, but is by no means limited thereto.

On the other hand, a reader is associated to the collection container for recognizing or reading the identification feature. This enables already the identification and association. Finally, a weighing device for weighing the receptacle before and after emptying, as well as a computer with a memory unit for storing the weight difference of the receptacle before and after its emptying are needed, so that the weight can be stored or further processed with association of the identification feature.
In a simple embodiment of the data acguisition system in accordance with the invention, the identification feature is a readable identification number. The reader associated to the collection container operates by light optics. The identification feature or the readable identification number could be glued, or painted or sprayed onto the receptacle.
Likewise however, the identification feature could be applied to or glued on the receptacle in the form of a bar code. This bar code would then have to be read by the operating personnel with a reader in the form of a bar code pin reader associated with the collection container or computer respectively. Aside from the known bar codes, it would be possible to use any coding which is readable or unreadable by a human ,. . .

2 ~ i 2 being, and suitable for a light-optical, automatic reading by means of a corresponding reader.
As regards an acquisition of data suitable for electronic data processing, it will be especially advantageous to provide the identification feature encoded in a code carrier. The latter could be releasably attached to the receptacle. To avoid that the code carrier associated to the respective receptacle is easily manipulatable by the collector, is t advantageous that the code carrier can be removed from the receptacle only by means of a special tool. As a - further protection against unlawful manipulations, the code carrier could be lead-sealed to the receptacle.
To reduce the cost incurred with securing the code carrier against manipulations or even its removal or exchange, the code carrier could be attached to the receptacle stationarily, i.e. not removably. In an advantageous manner, this could be accomplished in that the code carrier is made integral with the receptacle.
In such an instance, the code carrier with an unchangeable identification feature would be associated to or "incorporated" in the receptacle, for example, already during its manu~acture.
Likewise, the code carrier could be integrated in or attached to a handle of the receptacle. An advantage of this arrangement of the code carrier can be seen, among other things, in that the handle of the receptacle is always easily i accessible, and thus likewise the code carrier which is attached thereto or provided thereon for the reader.
In particular in the case of a subsequent, i.e. not integrated arrangement of the code carrier, it is advisable to protect same against a harmful atmosphere or dirt as well as excessive mechanical stress. To this end, it will be advantageous to seal the code carrier in a plastic housing, which would naturally have to be transparent, when an ~.
2 ~
identification feature to be read by light optics is used.
In particular with regard to an unobstructed data transmission and continuing data processing, the code carrier itself could be made in an especially advantageous manner as a wireless operating, electronic code carrier. In this instance, the code carrier would contain the identification feature in an encoded, unchangeable form, which is read by the reader in noncontacting manner.
As regards the supply of energy to such a code carrier, it would be of advantage, in particular with respect to the space necessary for installation, if the code carrier operated without its own, i.e.
internal supply of energy. To realize this, the code carrier could receive the necessary energy during the reading by induction via the reader, for example, by -means of high-frequency waves. However, it should also be ensured that the identification feature remains -~
permanently stored in the code carrier also over a `
longer period of time without an inductive supply of energy via the reader.
In a particularly advantageous manner, the code carrier is provided with a miniaturized sender, and the collection container or the reader has a miniaturized receiver. In this instance, the identification feature will be transmitted, when the reader supplies energy by induction, to the reader, and received by the receiver provided therein. Such a combination of sender and receiver would make it difficult to access or manipulate the code carrier without authorization.
To cope with any winter and summer temperatures, the code carrier should consist of such ~-materials that it operates without problems at temperatures ranging from -30C to +75C.
.' ~ .
, - ' , . , , . '' .' ' ., ~ . , . . ` ~ ' ' . .; ' 2~''&~2 In order to enable the operating personnel of the automatic data acquisition system in accordance with the invention to recognize the identification feature without technical aids, in particular for a proper return of the receptacle, it will be of great advantage, when for example the identification feature is arranged in addition on the code carrier or on the receptacle in a visible, i.e. readable form.
This arrangement will also be of great `r, importance, especially when the code carrier on the receptacle serving as a wireless data storage operates improperly or not at all. In such an event, it should be possible to manually input the number or the identification feature of the receptacle to be emptied.
The operator can read a glued on identification ` feature, for example a number, and communicate same by means of an intercom system to an operator of the memory unit. If the system of the present invention is used on a refuse collection truck, a worker would read at a failure of the code carrier the respective number and communicate same via an intercom system to the driver in the cab. The driver would then input this number via a key pad for further processing.
A further characteristic resides in that the intercom system could be automatically connected at a failure of the code carrier. Since the refuse collector wears thick working gloves in particular in winter, the operation of the key pad by the driver is especially advantageous inasmuch as the latter is anyway idle while the refuse container is emptied.
Within the scope of one aforesaid, especially preferred application of the data acquisition system of the present invention, the concern is the removal of refuse. The receptacle in this instance is a refuse container. The collection container would then be associated with in known manner with a refuse collection truck. The operating personnel of the .
. .
2 Q ~ 2 refuse collection truck would empty the refuse container or the like in known manner into the refuse collection truck. This procedure remains also unchanged in accordance with the teaching of the present invention.
To raise the refuse container, the collection truck is provided in known manner with a lifting mechanism. To determine the weight of the full and the emptied refuse container, the lifting mechanism itself is provided with power sensors, so that the weight of ., the full refuse container and the emptied container can be determined in a simple manner respectively when the refuse container is lifted and set down.
To ~e able to dynamically weigh in a particularly advantageous manner, it is necessary to consider the acceleration of the earth or respectively the mass inertia when lifting the refuse container, so as to avoid a false determination of the weight.
Otherwise, it would be necessary to weigh in an operating phase, in which neither an increase nor a decrease of speed occurs, i.e. in which neither positive nor negative accelerations occur. To realize such a dynamic determination of weight, while eliminating the mass inertia or respectively the acceleration of the earth, at least one acceleration sensor is provided in a particularly advantageous manner, which is preferably associated with the lifting ;
mechanism. The acceleration sensor picks up the speed of the refuse container and corrects accordingly the result of the weighing while considering the negative or positive acceleration. In this instance, for example a commercially available acceleration pickup or a standard force gauge is used as a sensor. Besides the acceleration sensor, it is advantageous to provide likewise an inclination sensor. While the weight is determined, the following occurs:
'f -, :.
'' ' .
.. ..
., "' 9 2 ~ 2 A known weight (dead load) undergoes the same acceleration as the receptacle to be emptied with the refuse contained therein. When now an acceleration occurs as the refuse container is lifted, the weight of the weighing container with the refuse therein increases percentagewise at the same ratio as the weight of the dead load at the reference sensor. This allows to compensate for the change in weight of the refuse in the receptacle with unknown weight, which is prodl~ced by negative or positive acceleration.
Likewise, the method under discussion allows to advantageously compensate for any factors which influence the weight determination, for example, also vibrations of the vehicle. Naturally, the application of the above-described compensation of the dynamic when determining the weight is not limited to the case of refuse collection.
As the weight is determined during th~
lifting operation, however, the problem arises that any ballast adhering to the refuse container, such as for example snow in winter, is likewise weighed. When the refuse container is emptied, this ballast drops, i.e., it is added to the weight of the material to be discharged. Accordingly, the customer would pay for the snow which dropped during the emptying.
.. . .
It is possible to eliminate the foregoing problem in that an intermediate container is provided.
i In this instance, the contents of the refuse containar ~1) are first emptied into the intermediate container, i.e., they are not weighed during the actual lifting operation. The intermediate container with the discharged material to be carried away is subsequently weighed with any ballast removed. Moreover, this further development of the teaching in accordance with the invention has the great advantage that in the case of multichamber refuse containers, it i5 possible to weigh sorted bulk material separately. -~ 2~g~2 In a particularly advantageous manner, a refuse discharge computer is associated with the collection container or respectively the refuse collection truck. The signal of the power sensor, which represents the weight of the full and the emptied refuse container, is input, preferably via a measuring amplifier, in this discharge computer which again controls the lifting mechanism.
With respect to a further processing of the data, the measuring amplifier is provided with a programmable intelligence in the meaning of a computer or microprocessor. The microprocessor of the measuring amplifier linearizes the measuring signals, and performs, if need be, a temperature compensation and an error correction.
To ensure a csrtain operational ease, it is of advantage, when the discharge computer is provided with an LCD and a key pad. The LCD could, for example, indicate the momentary operating mode of the discharge :
computer, but liXewise the identification feature of the refuse container which is just being emptied. The ;
key pad would allow to manually input data or commands.
Such an input would be necessary, for example when, for any reasons whatsoever, it would no longer be possible to electronically read the identification feature. In this instance, the operating personnel would have to read the identification feature or the identification number and input same manually via the key pad. Absent ~ -a recognition of the identification feature, it would also be conceivable to input the name of the customer, to which the computer would automatically associate the correctly stored identification feature.
The discharge computer transmits in an advantageous manner the measured signals to an onboard computer in the cab of the refuse collection truck.
The onboard computer is provided with a microprocessor and, preferably, with an internal c~ock. Furthermore, ' .
', : - ... ' , . ,~ , ~ ' '` ' ' " . ` :
2 ~ 3 '~ 2 , . 11 the onboard computer may be integrated in the data acquisition system such that it coordinates the discharge of the refuse and the discharge computer.
If need be, a record printer is connected to the onboard computer. This record printer serves on the one hand to immediately prepare a trip report of the refuse collection truck. On the other hand, it can ; secure the determined data in written form for the event that all electronically stored data are lost as a result of a system error.
; As regards the data to be acquired as a whole, it will be of advantage, when besides the weight and the identification feature of the refuse container, the vehicle number of the refuse collection truck and .
the time of the emptying are recorded and stored in the onboard computer. This serves in particular to document the service rendered as a result of emptying the refuse containers. Moreover, any desired information to be predetermined by the operating personnel may be input, and associated with the identification feature.
With respect to securing and transmitting the data, it is particularly advantageous when the onboard computer is provided with mobile storage cards as an output medium. These storage cards will then serve at the same time as input medium for a preferably stationary central computer.
For a simpler handling, the mobile storage cards could be of the size of check cards. Likewise, it would be conceivable that the storage cards have ~heir own energy supply in the form of a miniature battery. Likewise, as regards the securing of data, the storage card could be protected in a particularly advantageous manner by a shielding against overvoltage and voltage discharge.
While foregoing a further data transmission by means of storage cards, the data gathered by means .
: .
of the data acquisition system of the present invention and, if need be, stored in the on board computer could in a particularly elegant manner be radioed directly to a preferably stationary processing center with a central computer. Likewise, it is possible to communicate these data by means of infrared light directly to the preferably stationary processing center, it being necessary in this instance that the latter be in direct vicinity.
In the event of transmitting the data by means of storage cards, the central computer would have to be provided with a card reader for reading the mobile storage cards. To prepare invoices or statistics, graphics or the like, it would also be possible to provide in addition a printer for printing out the data prepared by the central computer. , It is also possible to design and construct the lifting mechanism for emptying two receptacles or refuse containers, i.e. for a double discharge. In this instance, it is of particular advantage with -regard to an always required weighing accuracy, when the control for the lifting mechanism, preferably designed as a hydraulic control, is linked with the -onboard computer. As a result, a synchronization of the weighing and the control of the hydraulic is realized, so that the weighing device operates only in the measuring phase and not during the lifting operation-Within the scope of a further, advantageous embodiment, the receptacle or refuse container may have at least two chambers separated from one another, which is to be preferred especially from ecological viewpoints. In the chambers, the refuse is separated by kinds, and the collection container receives the sorted refuse accordingly separated.
To be able to check reliably the contents of a receptacle or the receptacles, in a particularly ;
:, : .
2 ~ g ~
advantageous manner, the contents of a receptacle or the receptacles to be emptied are detected via a camera system which is preferably associated with the lifting mechanism. In its place, or in addition, the contents of the receptacle may also be detected, as regards metal, via a metal sensor which is preferably associated with the lifting mechanism. Likewise, it is possible to arrange chemical or spectroanalytical sensors for the detection of paints, varnish and other chemicals.
To avoid that hazardous contents of the receptacle are not mixed with the so-called residual refuse in the collection container, a special device is provided for sorting out or separating special refuse that is detected.
Furthermore, it would also be possible to detect the contents of the receptacle with respect to its volume, preferably by means of level sensors. The latter could operate by induction, capacitance, or by the eddy-current principle. Level sensors operating by capacitance could advantageously be constructed as a capacitance strip. However, the level sensors could operate liXewise by light optics.
In the case of a receptacle having at least two chambers, the respective chambers should be detected each individually.
Furthermore, it will be of special advantage, when the components of the data acquisition system are interconnected, galvanically decoupled, via a preferably serial field bus system.
Finally, the code carrier could be provided, besides the identification eature, with a read-write memory. Accordingly, the reader would be constructed as a read-write device. When the receptacle is emptied, all detected data could then be written via the read-write device into the memory, so that always cumulated data are associated to the receptacle, which ' :
~, 2~8~2 may be requested by the owner of the receptacle for a check, if need be.
The portion of the problem underlying the teaching of the present invention, which relates to a method, is solved in that a method of automatically acquiring data of refuse comprises the following steps:
before the start of the work or trip, a mobile storage card is inserted into the onboard computer of the refuse collection truck. As usual, the refuse containers are emptied, with the following occurring:
before or during the lifting of the refuse container, a noncontacting reader reads the identification feature.
The latter is transmitted via a discharge computer to the onboard computer where it is stored. Subsequently the weight of the full refuse container is determined via power sensors provided in the lifting mechanism, and likewise transmitted, via the discharge computer to the onboard computer. The emptied refuse container is lowered in the usual manner, with the weight of the emptied refuse container being determined via the power sensors provided in the lifting mechanism, and likewise transmitted via the discharge computer to the onboard computer. The weight difference, i.e., the weight of the emptied refuse, is stored in the onboard computer or on the mobile storage card and associated to the pertinent, previously read identification feature, it being likewise possible to associate to the identification feature, if need be, further data, such as for example, time, vehicle number, or the like. If desired, a record printer will print out the determined and associated data. At the end of the trip, the mobile storage card is removed from the onboard computer and delivered to the processing center. The storage card or the data stored on the storage card are read via a card reader of the central computer and evaluated by the latter. The evaluation serves~ for example, to prepare invoices, statistics, and other ' ~i :

evaluations by means of printers, plotters, or the like.
