Description

BRIEF DESCRIPTION OF THE EMBODIMENTS

(1) The invention will be described in more detail in the following referring to drawings depicting merely exemplary embodiments. In the drawings:

(2) FIG. 1 shows a schematic diagram of a suggested agricultural work situation;

(3) FIG. 2 shows a schematic diagram showing cases of use of the suggested agricultural work situation; and

(4) FIG. 3 shows a schematic depiction of the communication between the pattern recognition system and individual functional units of the suggested agricultural work system.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(5) Referring to the drawings, FIG. 1 schematically shows the basic construction of the suggested agricultural work system 1 for optimizing agricultural work flows. Agricultural work system 1 has at least one agricultural work unit 2, 3, in this case two agricultural work units 2, 3. In the example depicted here, the two agricultural work units 2, 3 are agricultural work machines, for example, a combine harvester 4 shown at bottom left in the diagram and, for example, a tractor 5 with a transporting trailer 6 as mounted implement, shown at bottom right in the diagram. Agricultural work unit 2, 3 can also be formed by a mounted implement as such, for example, by a plow, a cultivator, a harrow, a mower, a baler 7 or the like instead of by an agricultural work machine. Additionally or alternatively, an agricultural work unit 2, 3, as meant herein, can also be formed by a stationary agricultural arrangement such as a grain drying arrangement 8, a grain store 9, a workshop area 10 or the like.

(6) The suggested agricultural work system 1 has a plurality of functional units 11, 12 for implementing or supporting agricultural work which have in each instance a control device 13 for controlling the respective functional unit 11, 12, particularly based on a stored set of rules 14. In the depicted embodiment example, the functional units 11, 12 are identical to the agricultural work units 2, 3; that is, one functional unit 11 is formed by combine harvester 4 and the other functional unit 12 is formed by tractor 5. In the present instance and preferably, each functional unit 11, 12 has one or more work assemblies for implementing or supporting agricultural work. As meant herein, work assemblies are in particular a traveling drive 15 of the agricultural work machine, a steering system 16 of the agricultural work machine, a crop-processing work assembly such as a cutter 17, a thresher and/or a load transferring device 18 or a driver assistance system of the agricultural work machine which, in particular, controls a plurality of work assemblies during the agricultural work flows and, in particular, also comprises control device 13.

(7) In an alternative embodiment example, not shown, the mounted implement can also have work assemblies. For example, a baler can have a crop pickup device and a crop pressing device. A stationary agricultural arrangement can also have work assemblies as functional unit. For example, a grain drying arrangement can have a grain feeding device and a heating device.

(8) The suggested agricultural work system 1 further has a central pattern recognition system 19. At least one agricultural work situation is stored as a situation pattern 20a, 20b, 20c in pattern recognition system 19. In this case, for example, three different situation patterns 20a, 20b, 20c are stored, each of these situation patterns 20a, 20b, 20c representing a different work situation. As meant herein, a work situation is a particular situation in which a determined agricultural work flow is to be carried out as part of a work order. In a merely exemplary manner and not exhaustively, this includes the work situation during brush cutting, the work situation when harvesting along a wheel track in the field, the work situation when approaching a headland, the work situation in the headland, the work situation when approaching an obstacle, the work situation during accompanied travel, for example, for the purpose of load transfer, the work situation during the load transferring process, the work situation during grain collection, the work situation during straw baling, or the work situation during straw bale collection. Each of these work situations requires a determined work sequence which in turn requires parameter adjustments of one or more work assemblies of an agricultural work unit 2, 3, for example, of an agricultural work machine. In an exemplary and purely schematic manner, FIG. 1 shows a load transferring process in which a combine harvester 4 as one functional unit 11 follows closely alongside a tractor 5 forming a further functional unit 12 and is coupled with a transporting trailer 6 as a mounted implement for pickup of the grain by combine harvester 4. In this work situation, for example, the respective control device 13 must control the respective traveling drive 15 and the respective steering system 16. The driving movements of the two traveling drives 15 and the steering movements of the two steering systems 16 must be coordinated. Further, in the functional unit 11 formed by the combine harvester 4, the cutter 17 and load transferring device 18, inter alia, must be controlled. The movements of these two devices 17, 18 must also be coordinated.

(9) In order to optimize the required work flow of the two agricultural work units 2, 3, i.e., in this instance combine harvester 4 and tractor 5, a plurality of, particularly multiple, work situation-specific information I is transferred to pattern recognition system 19. The work situation-specific information I is information or data which are related to the impending and/or present work situation and/or which are suitable for defining the impending and/or present work situation. In the present instance and preferably, the work situation-specific information I is determined by the functional units 11, 12 themselves, possibly also additionally by further functional units of agricultural work system 1, and is transferred to pattern recognition system 19.

(10) Pattern recognition system 19 is configured such that it identifies a stored work situation and the associated situation pattern 20a, 20b, 20c based on the obtained work situation-specific information I. In particular, pattern recognition system 19 matches the individual obtained data with the stored situation patterns 20a, 20b, 20c. If a matching situation pattern 20a, 20b, 20c has been identified based on the data, pattern recognition system 19 transmits meta-information M characterizing the identified work situation to the plurality of functional units 11, 12. The meta-information M is a communication about the identified work situation which, in the present instance and preferably, is limited to the strict indication of the identified work situation in the form of the designation or a description of the work situation and accordingly in particular contains no work instructions. Correspondingly, the meta-information preferably includes no parameters, parameter sets or parameter sequences (parameters changing in temporal succession) for controlling the respective functional unit and/or no references to parameters, parameter sets or parameter sequences stored in the respective functional unit for controlling the respective functional unit. Rather, in the present instance and preferably, the functional units 11, 12 must themselves generate corresponding parameters, parameter sets or parameter sequences for the identified work situation based on the communicated work situation, i.e., the meta-information M, and carry out corresponding parameter adjustments.

(11) In an alternative embodiment example, not shown, it can also be provided that the meta-information M also contains—in addition to the data comprising a designation and/or description of the work situation—parameters, parameter sets or parameter sequences for controlling the respective functional unit 11, 12 and/or references to parameters, parameter sets or parameter sequences for controlling the respective functional unit 11, 12 that are stored in the respective functional unit 11, 12.

(12) The meta-information M contains particularly data which comprise a designation and/or description of the “brush cutting” work situation, the “harvesting along a wheel track in the field” work situation, the “approaching a headland” work situation, the “headland” work situation, the “approaching an obstacle” work situation, the “accompanied travel” work situation, the “load transferring process” work situation, the “grain collection” work situation, the “straw baling” work situation and/or the “straw bale collection” work situation.

(13) It should be emphasized that the meta-information M which is generated and conveyed by pattern recognition system 19 is not compulsorily conveyed only to the two functional units 11, 12 working together with one another in the respective work situation, but rather can also be conveyed to other functional units of the agricultural work system 1, which is symbolized in FIG. 1 by two arrows which proceed from pattern recognition system 19 and do not lead to any of the functional units shown. All of the functional units of the agricultural work system 1 detect, particularly independently, whether or not the received meta-information M applies to them. The respective control device 13 responds only in case the meta-information M relates to it, as is the case here with functional units 11, 12.

(14) To this end, in the present instance and preferably, control devices 13 of the plurality of functional units 11, 12 are configured to coordinate the cooperation of those functional units 11, 12 that work together in the identified work situation based on the meta-information M. In the course of this coordination, control devices 13 carry out corresponding parameter adjustments of the associated functional unit 11, 12. Accordingly, in the present instance and preferably, the meta-information M is a trigger which activates control devices 13 so that the latter generate parameters, parameter sets and/or parameter sequences and carry out corresponding parameter adjustments. Additionally or alternatively, pattern protection system 19 can be configured to coordinate the cooperation of those functional units 11, 12 working together in the identified work situation based on the meta-information M. In this case also, control devices 13 carry out corresponding parameter adjustments of the associated functional unit 11, 12.

(15) As mentioned previously, functional units 11, 12 can be formed by different agricultural work units 2, 3. Accordingly, functional units 11, 12 are, for example, an agricultural work machine, a mounted implement which is coupled or coupleable with an agricultural work machine, and/or a stationary agricultural arrangement. In an alternative embodiment, not shown, functional units 11, 12 can also be formed by different work assemblies of an agricultural work unit 2, 3. For example, a functional unit 11, 12 can be a traveling drive 15 of the agricultural work machine, a steering system 16 of the agricultural work machine, a driver assistance system of the agricultural work machine, a crop-processing work assembly of the agricultural work machine or of the stationary agricultural arrangement and/or a crop-processing work assembly of the mounted implement.

(16) In the present instance and preferably, pattern recognition system 19 is configured to receive individual or a plurality of work situation-specific information I from sensors 21 of the at least one agricultural work unit 2, 3 or of the plurality of agricultural work units 2, 3. In this case, it can further be optionally provided that work situation-specific information I can be entered by the operator via an input device 22 of the agricultural work unit 2, 3, which work situation-specific information I is likewise received by pattern recognition system 19.

(17) In the present instance and preferably, pattern recognition system 19 has a communications interface 23 for receiving the work situation-specific information I and for conveying the meta-information M to functional units 11, 12. Further, pattern recognition system 19 has a computer 24 for processing the individual received work situation-specific information I and a data storage 25 in which the situation patterns 20a, 20b, 20c are stored. In the present instance and preferably, computer 24 and data storage 25 are a component part of a cloud 26, that is, are provided via the Internet. Accordingly, pattern recognition system 19 is preferably partially or completely cloud-based. However, it is also conceivable to provide this in association with a machine, that is, in an agricultural work machine, and/or in a stationary manner, that is, in a localized manner, for example, in a data processing installation on an agricultural operation.

(18) Functional units 11, 12 also preferably have in each instance a communications interface 27. This serves in every case to receive meta-information M. Further, communications interface 27 can also be configured to transmit work situation-specific information I. In the present instance and preferably, communications interface 27 is further configured to exchange data with a communications interface 27 of another functional unit 11, 12 so that it is possible to coordinate the cooperation by direct route.

(19) In the present instance and preferably, control devices 13 of functional units 11, 12 have in each instance a microcontroller 28 for processing the respective meta-information M and a data storage 29 in which the set of rules 14 is stored. The set of rules 14 can have parameters, parameter sets and/or parameter sequences for at least one work assembly of agricultural work unit 2, 3 which are associated respectively with different work situations. The respective control device 13 can then adjust at least one parameter, at least one parameter set and/or at least one parameter sequence for at least one work assembly of agricultural work unit 2, 3 based on the obtained meta-information M and coordinate the at least one adjustment with at least one adjustment of another functional unit 11, 12 based on the same meta-information M.

(20) The work situation-specific information I is preferably structured and contains work situation-specific information I from one or more hierarchically distinct situation levels E, E.sub.0, E.sub.1, etc. Accordingly, work situation-specific information I can be determined relating to at least one main work situation, at least one auxiliary work situation, at least one propulsion situation, at least one machine situation, at least one safety situation, at least one automation level, at least one simulation situation and/or at least one load situation and can be conveyed to pattern recognition system 19.

(21) Work situation-specific information I relating to a main work situation or to a work situation of a main situation level E.sub.0 can contain at least work situation-specific information I for defining the preparation of a work order and/or for defining the environment (e.g., road, field) and/or for defining the work order (e.g., grain harvesting, soil tillage, etc.) of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(22) Work situation-specific information I relating to an auxiliary work situation or to a work situation of a subordinate auxiliary situation level E.sub.1 can contain at least work situation-specific information I for defining a subordinate task (e.g., brush cutting, harvesting along a wheel track in the field, approaching a headland, traversing a headland, approaching an obstacle, accompanied travel, load transferring process, grain collection, straw baling, straw bale collection) of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(23) Work situation-specific information I relating to a propulsion situation or to a work situation of a further subordinate situation level can contain at least work situation-specific information I for defining a movement state and/or traveling state (e.g., standstill, stationary, forward, reverse) of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(24) Work situation-specific information I relating to a machine situation or to a work situation of another subordinate situation level E.sub.1 can contain at least work situation-specific information I for defining a machine state (e.g., main assembly “on”, main assembly “off”) of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(25) Work situation-specific information I relating to a safety situation or to a work situation of another subordinate situation level can contain at least work situation-specific information I for defining the functional safety of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(26) Work situation-specific information I relating to an automatic level or to a work situation of another subordinate situation level can contain at least work situation-specific information I for defining an adjusted driving mode or driving mode level (Level 1: internal automation, Level 2: automatic cutter control, Level 3: automatic field travel, Level 4: remote-controlled field travel, Level 5: autonomous field travel, Level 6: automatic road travel) of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(27) Work situation-specific information I relating to a simulation situation or to a work situation of another subordinate situation level can contain at least work situation-specific information I for defining a simulation of a work order.

(28) Work situation-specific information I relating to a load situation or to a work situation of another subordinate situation level can contain at least work situation-specific information I for defining a load state (e.g., capacity used up, full capacity available) of the agricultural work unit or of another, particularly adjacent, agricultural work unit.

(29) The data exchange between pattern recognition system 19 and the respective functional unit 11, 12 and/or the data exchange between functional units 11, 12 is carried out in the present instance and preferably in real time. Particularly preferably, the data exchange is carried out wirelessly.

(30) In the present instance and preferably, the suggested agricultural work system 1 is expandable modularly by further functional units (not shown) for implementing or supporting agricultural work. Each of the further functional units can correspond to the functional units 11, 12 described above with respect to construction and manner of functioning.

(31) FIG. 2 shows the suggested agricultural work system 1 for the agricultural case of use of grain harvesting and the corresponding subordinate tasks such as harvesting along a wheel track in the field, the load transferring process, grain collection in the operation yard and straw baling.

(32) An agricultural operation having a workshop area 10 in addition to a grain drying arrangement 8 and a grain store 9 is shown schematically at lower right in FIG. 2. The agricultural operation, as such, and its stationary structural units comprising grain drying arrangement 8, grain store 9 and workshop area 10 form stationary functional units 11, 12 of the suggested agricultural work system 1.

(33) The agricultural operation is connected to a plurality of lands to be processed, in this case crop areas A.sub.1, A.sub.2, A.sub.3, by a network of roads and paths of any configuration.

(34) Two agricultural work machines constructed as combine harvesters 4 are in use for harvesting on a first crop area A.sub.1. One combine harvester 4 passes through the field crop and a further combine harvester 4 travels through the headland. The two combine harvesters 4 form further functional units 11, 12, in this case mobile functional units 11, 12, of the suggested agricultural work system 1. The combine harvesters 4 store the harvested fructification parts, in this case cereal grain, in a tank associated with the machine in a conventional manner, per se, until a load transferring process, while the straw generated by the harvesting process is put down as swath on crop area A.sub.1 in the rear area of the combine harvester 4.

(35) Two further agricultural work machines constructed as combine harvesters 4 perform harvesting work in a similar manner on a further crop area A.sub.2, for example, simultaneously or at different times. These two combine harvesters 4 form further functional units 11, 12, in this case mobile functional units 11, 12, of the suggested agricultural work system 1. Accordingly, the depicted processing of agricultural crop areas A.sub.1, A.sub.2 reflects a typical use of combine harvesters 4 in harvesting, since in the case of large parcels of land A.sub.1, A.sub.2 a plurality of agricultural work machines generally execute an agricultural work order jointly for reasons of economy. A possible load transferring process between one of the combine harvesters 4 and a tractor 5 and transporting trailer 6 working in tandem is depicted in FIG. 2 above crop area A.sub.2.

(36) A further crop area A.sub.3 is shown on which, for example, simultaneously or at different times, a baler 7 drawn by a tractor 5 presses the crop put down in swaths into bales of crop. The tractor 5 forms a further functional unit 11, 12, in this case a mobile functional unit 11, 12, of the suggested agricultural work system 1.

(37) Finally, further tractors 5 and transporting trailers 6 acting in tandem are depicted traveling along the network of roads and paths with the aim of loading and unloading the grain. The tractor 5 and transporting trailer 6 are empty in two cases and full in one case. Each of these tractors 5 forms a further functional unit 11, 12, in this case a mobile functional unit 11, 12, of the suggested agricultural work system 1.

(38) Each of the situations mentioned above which are shown schematically in FIG. 2 represents an agricultural work situation within the meaning of the present application. Each of these work situations corresponds to a situation pattern 20a, 20b, 20c which is stored in the central pattern recognition system 19 and which can be identified by pattern recognition system 19 based on received work situation-specific information I. Following the identification of a determined situation pattern 20a, 20b, 20c and in accordance with an identified work situation, the pattern recognition system 19 transmits meta-information M characterizing the identified work situation to the functional units 11, 12 shown in FIG. 2 in the manner described above.

(39) For example, the transfer of grain to the grain drying arrangement 8 is identified (“grain collection” situation pattern) as work situation for the agricultural operation. The harvesting of a field, in this instance a grain field, along wheel tracks (“harvesting along a wheel track in the field” situation pattern) is identified, for example, as work situation for the first crop area A.sub.1. The transfer of harvested fructification parts, in this instance cereal grain, is identified (“load transferring process” situation pattern), for example, as work situation for the second crop area A.sub.2. The pressing of bales, in this instance round bales, is identified (“straw baling” situation pattern), for example, as work situation for the third crop area A.sub.3.

(40) As has already been mentioned, the work situation-specific information I which is transmitted to pattern recognition system 19, contains particularly information from a plurality of situation levels E, E.sub.0, E.sub.1, etc. Work situation-specific information I contains, for example, at least information relating to a main work situation and an auxiliary work situation. In this instance, a subordinate, global “grain harvest” situation pattern, for example, is associated with a main work situation. In this instance, merely by way of example and not exclusively, the “harvesting along a wheel track in the field”, “load transferring process”, “grain collection” and “straw baling” situation patterns are associated with an auxiliary work situation in pattern recognition system 19.

(41) All of the functional units 11, 12 shown in FIG. 2 and the control units 13 thereof are configured in this instance and preferably in such a way that the control devices 13 of those functional units 11, 12 which work together in the identified work situation coordinate their cooperation based on the obtained meta-information M and execute parameter adjustments of the associated functional unit 11, 12.

(42) For example, parameter adjustments of traveling drive 15 and of steering system 16, inter alia, are carried out by the control devices 13 of every functional unit 11, 12 based on the “load transferring process” situation pattern so that combine harvester 4 and tractor 5 meet one another at an optimal time in optimal orientation. The rest of the functional units 11, 12 also obtain the meta-information M but detect independently that they are in a different work situation and accordingly do not react to the meta-information M.

(43) In a further embodiment example, the operator specifies the “brush cutting” work situation via the input device 22 of a first work unit 2, 3 configured as combine harvester as work situation-specific information I. This work situation-specific information I is then transferred to pattern recognition system 19 which subsequently identifies the stored “brush cutting” work situation and the associated situation pattern 20a, 20b, 20c based on the obtained work situation-specific information I. Pattern recognition system 19 generates and then transmits meta-information M characterizing the identified “brush cutting” work situation to all of the further work units 2, 3 of the agricultural work system 1 which form a functional unit 11, 12 in each instance, including in particular at least one further combine harvester and at least one unloading vehicle.

(44) The cooperation of the work units 2, 3 working together in the “brush cutting” work situation is coordinated based on the meta-information M in that parameter adjustments specifically provided for the “brush cutting” work situation are carried out in the first work unit 2, 3 formed as combine harvester, and/or in that a further combine harvester is requested as further work unit 2, 3 for the “brush cutting” work situation, and/or in that an unloading vehicle is requested as further work unit 2, 3 for a “load transferring process” work situation following the “brush cutting” work situation.

(45) As has already been mentioned, the suggested agricultural work system is generally configured in such a way that individual or a plurality of work situation-specific information I is transferred to pattern recognition system 19 from one or more devices for acquiring work situation-specific information I. In a particularly preferred manner, the work situation-specific information I is transferred to pattern recognition system 19 from one or more work units 2, 3, from one or more functional units 11, 12, from one or more sensors 21 of at least one of the work units 2, 3, from one or more input devices 22 for operator input of work situation-specific information I, and/or from one or more further devices for acquiring work situation-specific information I. In the present instance and preferably, pattern recognition system 19 transmits the transferred work situation-specific information I and/or the meta-information M generated based on the latter by pattern recognition system 19 back to one or more of these devices, particularly all of these devices.

(46) Finally, FIG. 3 schematically shows the communication between pattern recognition system 19 and individual functional units 11, 12 of the suggested agricultural work system 1. The communication is bidirectional (indicated by a double arrow) in some functional units 11, 12, i.e., is carried out in both directions between pattern recognition system 19 and functional unit 11, 12. In other functional units 11, 12, the communication is unidirectional (indicated by a single arrow), i.e., is carried out either only from pattern recognition system 19 to functional unit 11, 12 or only from functional unit 11, 12 to pattern recognition system 19. Optional communication paths are shown in dashed lines.

(47) Shown on the left-hand side as functional units 11, 12 by way of example are, from top to bottom, a transverse control unit, a longitudinal control unit, an “autofill” control unit, an operator display for displaying a target setting, an operator display for displaying status, an operator display for displaying prompts, alerts, and/or optimization suggestions, an (optional) storage or external services for data recording, a storage or external services for data analysis, a storage or external services as operations center, a simulation unit for simulating individual machine functions, and a simulation unit for simulating machine movements.

(48) Shown on the right-hand side as further functional units 11, 12 by way of example are, from top to bottom, a sensor unit with at least one sensor for generating unprocessed signals, a sensor unit with at least one expanded sensor with signal processing, a module for communications, a module in the form of an operator device, a function module in the form of the machine, a function module in the form of the mounted implement, a function module in the form of a steering module, a function module in the form of a logistics module, a function module in the form of an optimization module (precision applications), for example, in the form of an automatic swath controller (section control) or in the form of a variable application rate control (variable rate control), and a functional module in the form of a route planning module.
