    Arrangement for the automatic recognition of the configuration of a drive train and / or the number of active movable elements of a working member of a
    working machine
    The invention relates to an arrangement for the automatic detection of the configuration of a drive train for driving a working member of a working machine and / or the number of active moving elements of a working member of a working machine, with a control unit and a cooperating with the working organ sensor whose output signal is evaluable by the control unit Information about the configuration and / or the number of active moving elements of the working organ contains.
    State of the art
    Work machines of all kinds are currently being increasingly equipped with electronic control units that serve to adjust or regulate Betriebsparametem individual components of the machine. The controllers, in turn, require data regarding the particular configuration of the work machine to adequately control it. In order to set the cut length to a desired value in a forage harvester by the speed of Vorpress rollers is set accordingly, the control unit, for example, information regarding the proportionality factor between a detected speed of the pre-compression rollers and the peripheral speed of the pre-compression rollers on the one hand and the number of knives the Chopper drum and their speed on the other hand present. Usually, the fixed data (such as the proportionality factor between the speed of the pre-compression rollers and their peripheral speed) in the control unit fixed or changeable programmed, while the number of blades during the manufacture of the machine or after a change by the operator in the
    Control unit is programmed. In this case, errors are possible, which in turn unenviable functional problems of the machine result in a forage harvester z. B. too short or too long cutting lengths.
    It has also been proposed to detect in a forage harvester for the purpose of correct automatic cutting length adjustment, the number of knives by a sensor not described in detail (DE 196 32 977 Al).
    It has also been proposed to detect vibrations in agricultural machines and to assign them to certain components on the basis of their frequencies (EP 1 221 280 A1). For this purpose, an analysis device whose speed or the gear ratio, with which they are driven by the internal combustion engine ago, already be known. Here, too, therefore, there are possibilities for error if, during the assembly of the work machine or after a conversion, incorrect entries concerning the gear ratio are made inadvertently.
    task
    The problem underlying the invention is seen to provide an arrangement and a method which make it possible without great effort to automatically recognize the configuration of a drive train for driving a working member of a working machine and / or the number of active moving elements of a working organ.
    solution
    This problem is solved according to the invention by the teaching of claims 1 and 11, which are listed in the other claims features that further develop the solution in an advantageous manner.
    An arrangement for the automatic recognition of the configuration of a drive train, which serves to drive a working member of a work machine, and / or for the automatic detection of the number of active movable elements of a working member of a work machine and a corresponding method comprise an electronic control unit and a cooperating with the working organ sensor , The output signal of the sensor contains
    Information regarding the configuration of the drive train and / or the number of active moving elements of the working organ. The control unit compares in operation the signals of the sensor and / or derived values, for example a frequency spectrum, with a database in which iur different, provided by the manufacturer of the working machine configurations of the drive train and / or numbers of active moving elements of the working organ associated Pattern are stored. The pattern in the database that best suits the detected signals and / or values derived therefrom is found out, and the control unit then outputs output data regarding the powertrain configuration and / or the number of active moving elements of the work organ.
    In this way, an automatic detection of the configuration of the drive train and / or the number of active moving elements of the working organ is easily possible, even if the manufacturer should be provided a variety of possible configurations or numbers. The automatic detection has the advantage that no incorrect inputs by an operator or by the production staff are more possible and that any changes in the event of a modification of the machine can be detected automatically.
    When determining the powertrain configuration, it may be useful to provide the control unit with data regarding the input rotational frequency of the powertrain and the rotational frequency of the powerplant. The control unit uses the ratio between the rotational frequency of the working element and the input rotational frequency of the drive train as a parameter to extract from the database the respective configuration of the drive train. For this purpose, different ratios between the rotational frequency of the working element and the input rotational frequency of the drive train and associated configurations are entered in the database. Examples of removable from the database configurations would be in a gear transmission whose transmission ratio (or numbers of teeth) and in a belt transmission, the pulley sizes. It is exploited that on the part of the manufacturer only certain numbers of teeth and gear ratios or
    Pulley sizes are used.
    A preferred embodiment of the invention uses as a sensor a vibration sensor which is arranged to detect vibrations generated by the moving working member.
    The signals of such a sensor can be used to determine the speed of the working organ, by deducing from them the Grundffequenz, which in turn corresponds to the speed of the working organ. Alternatively or additionally, however, the control unit can also use other data relating to the rotational frequency of the working member, such as the above-mentioned transmission ratio of the drive train of the working member and its input rotational frequency. Furthermore, the control unit evaluates the signals of the sensor at one or more harmonic frequencies of the fundamental frequency in order to compare the signals of the sensor at one or more frequencies of the fundamental frequency with corresponding patterns stored in the database Work organ to determine and provide as output. One makes use of the fact that the detected signal amplitudes at the individual nth order levels depend on the number n of movable elements.
    For example, if only two elements are distributed around the circumference of the working organ, a relatively high amplitude at twice the fundamental frequency is to be enzvarten. If, analogously, 123 elements are distributed around the circumference of the working element, a relatively high amplitude at 123 times the fundamental frequency is to be expected.
    A further refinement provides that the elements of the working member are mounted in several rings distributed around the working member. The individual rings may comprise different numbers of elements. The control unit is additionally designed in this case to recognize the different numbers of elements of the rings. A typical application for this would be a so-called Dutch configuration of a chopper drum, where in the middle two out of four rings of chopper knives, every other knife is removed or placed in an inactive, d. H. pushed inward position is spent so that it does not interact with the Emtegut.
    A preferred application of the present invention resides in a forage harvester where the working member is the forage harvester drum and the movable elements are chopper knives cooperating with a bedknife. Also accidentally in the inactive position reached (slipped) knives are detected with the inventive arrangement and can be displayed to the operator for correction. But there are also other applications of agricultural harvesters conceivable, for example, to detect the number of Dreschleisten a threshing drum or the blades of a straw chopper of a combine harvester. The automatically recognized configuration of the drive train can also be used to evaluate the vibration spectra for the detection of a possible error (see EP 1 221 280 A1, the disclosure of which is incorporated by reference into the available documents).
    It is advisable to use the automatically detected by the control unit number of active, movable elements of the working organ, to control other components of the machine, for example, to set or regulate a manually entered or predetermined by a sensor cutting length. It is further proposed that the control unit emits a warning signal and / or prevents the operation of the work machine, if an improper or inadmissible configuration of the drive train and / or the number of active movable elements of the working organ is detected. In this way, for example, it can be prevented that a cutterhead of a forage harvester is put into operation, which is inadvertently equipped with chopping knives only on half of the circumference.
    The control unit can determine the configuration of the drive train and / or the number of active moving elements of the working member immediately after the completion of the work machine still in the production line. There can also be a comparison with an order database to ensure that the ordered or a legal configuration was mounted on the machine. Errors before delivery are thus prevented and could also be subsequently analyzed in the case of recourse claims, for which purpose the determined configuration would have to be stored by the manufacturer. In addition, the configuration of the drive train and / or the number of active moving elements of the working member can be determined at intervals, for example, with a driven working member and no Emtegutdurchsatz at the field end.

    An embodiment of the invention will be explained with reference to the drawings. Show it:
    Fig. 1 is a schematic side view of a self-propelled harvester in
    Shape of a forage harvester,
    2 is a schematic plan view of the drive system of the harvesting machine,

    Fig. 6 is a flow chart, according to which the control device proceeds in an automatic detection of the number of chopping blades of the cutterhead.
    In the figure 1 is shown as an example of a working machine, a harvester 10 in the manner of a self-propelled forage harvester in a schematic side view. The harvester 10 is built on a frame 12 supported by front driven wheels 14 and steerable rear wheels 16. The operation of the harvesting machine 10 is carried out by a driver's cab 18, from which a Emtevorsatz 20 in the form of a pickup is visible. By Emtevorsatzes 20 picked up from the ground Emtegut, z. B. grass or the like is fed via a feed conveyor 22 with Vorpresswalzen, which are arranged within a feed housing 24 on the front side of the forage harvester 10, arranged below the driver's cab 18, provided as a working organ chopper drum 26, which chops it into small pieces and one Releases conveyor 28. The crop leaves the harvesting machine 10 to a transporting vehicle traveling alongside by means of a discharge shaft 30 which can be rotated about an approximately vertical axis and tilted in the inclination. In the following, directional details, such as laterally, downwardly and upwardly, refer to the forward movement direction V of the harvesting machine 10, which in FIG the figure 1 runs to the right.
    FIG. 2 shows a plan view of the drive arrangement of the harvesting machine 10. In the rear region of the harvesting machine 10 there is an internal combustion engine 36 arranged at the rear of the rear axle, which is designed in particular as a diesel engine and connected to longitudinal members and / or cross members of the frame 12. The crankshaft 40 of the engine 36 extends in the forward direction of the harvester 10 and extends outward from the housing of the engine 36.
    The internal combustion engine 36 drives in operation with its crankshaft 40 to a longitudinal shaft 44, which is connected to the input-side bevel gear 48 of a transmission 52. The longitudinal shaft 44 also drives via the gears 70, 72 and another shaft 76 to a pump unit 74, which includes a hydraulic pump for driving hydraulic motors for propulsion of the harvester, a steering pump and a hydraulic pump for oil supply to the control of the hydrostatic drive for the propulsion of Harvesting machine 10 includes, and a first hydraulic pump 110, which serves to drive a first hydraulic motor 116 for driving the Emtevorsatzes 20. It would also be conceivable to drive further permanently driven elements, such as an electric generator and / or a blower drive for the cooling air supply for the internal combustion engine 36, via one of the gears 70, 72 or a toothed wheel (not shown).
    The output bevel gear 50 of the transmission 52 is connected to a transverse shaft 80 which extends through a coaxially arranged on a pulley 82 hollow shaft 106 and on which on the side facing away from the gear 52 side of the pulley 82 is connected to a clutch 78. To the pulley 82, a drive belt 84 runs around, which also rotates about a pulley 88 for driving the chopper drum 26 and a pulley 86 for driving the conveying device 28. The clutch 78 is the output side connected to the hollow shaft 106, which also on the gear 52 side facing the pulley 82 via gears 96, 108 and 100 drives a second hydraulic pump 102, which serves to drive a second hydraulic motor 112, the feed conveyor 22 via a gear 114 drives. The clutch 78 which can be actuated by means of an actuator 90 makes it possible to connect the drive belt 84 and with it the chopper drum 26 and the conveying device 28 to the quenelle 80 in order to drive it in emitter operation or to separate it from it.
    The chopper drum 26 cooperates with a counter-blade 38.
    FIG. 3 shows a perspective view of the chopper drum 26. It comprises a shaft 42 which is rotatably supported in the frame 12 and on which support disks 46 are mounted, around the circumference of chopping blades 54 are distributed. The chopping blades 54 are screwed to knife holder 56, which are screwed to the support plates 46 as shown here. The knife holder 56 could also be welded in a conventional manner on a separate drum shell (not shown). In the illustrated embodiment, the chopping blades 54 are arranged in four rings to each 12 chopping knives, the chopping blades 54 of the individual rings are each arranged angularly offset from each other.
    Reference is now made to FIG. The counter-blade 38 is provided with an adjusting device 58, which is adapted for moving the counter-blade 38 in the horizontal direction on the chopper drum 26 to and from her. It serves to adjust the size of the cutting gap. At both lateral ends of the counter cutting edge 38 on the frame 12 supporting counter cutting bed 60 each a vibration sensor 62 is arranged.
    The vibration sensor 62 attached to the counter cutting bed 38 is part of an arrangement for automatically recognizing the configuration of the drive train for driving a working member (namely, the cutterhead 26) of the harvester 10 and the number of active moving elements (chopping knives 54) of the working member shown in FIG shown in total. The vibration sensor 62 comprises a mass 64 suspended from springs 64, whose position can be detected by a position sensor 68 which, for example, operates capacitively or inductively. If the counter-blade 38 is accelerated, a carrier plate 118 of the vibration sensor 62, which is preferably detachably fastened to it, is accelerated, while the mass 66 initially remains stationary due to its inertia and only starts to move due to the suspension on the springs 64. The relative movement between the carrier plate 118 and the mass 66 is detected by the position sensor 68. In FIG. 4, the vibration sensor 62 detects obliquely downward and oscillating from the extending direction in an area of the counter cutting bed 60 adjacent to the chopper drum 26 because the springs 64 extend obliquely downward and downward. The sensitive direction of the vibration sensor 62 thus extends approximately parallel to the diagonal of the counter-blade 38. The position of the vibration sensor 62 or at least the springs 64 and the mass 66 may be adjustable, in particular rotatable about the longitudinal axis of the counter-cutting bed 60 or an axis parallel thereto, to be able to capture the vibrations generated by the chopper blades 54 when passing on the counter-blade 38 as well as possible. As indicated in FIG. 4, vibration sensors 62, 62 'may be disposed at both ends of the counter cutting bed 60 (or at any positions therebetween).
    The output signals of the position sensors 68 of the vibration sensors 62, 62 'are fed to a control device 120, which could be arranged, for example, in the driver's cab 18. The control device 120 comprises an amplifier 122, an analog / digital converter 124, a Fourier transformation device 126 and an evaluation circuit 128, which cooperates with a database 130 which is stored in a memory 132. The amplifier 122 amplifies the incoming signals of the vibration sensors 62 and possibly 62 ', while the analog / digital converter 124 converts the amplified output signals of the amplifier 122 into digital width. The
    Control device 120 is connected to a bus 136, a display device 134 and a controller 138 for controlling the hydraulic motor 112 and / or the hydraulic pump 102.
    FIG. 5 shows a flowchart according to which the control device 120 proceeds in order to determine the configuration of the drive train of the chopper drum 26. After the start in step 200, a query is made in step 202 as to whether the chopper drum 26 rotates without processing material being processed. This information may be obtained by means of associated sensors (a cutterhead rotation speed sensor 26 and a sensor detecting the drive power of the pre-press rollers 22 in the feeder housing 24) or the state of the actuator 90 and the position of the etched attachment 20 which may be excavated by an actuator 138 , be won. If the result of step 202 is negative, step 202 again follows. Otherwise, step 204 follows in that the control device 120 detects the output signals of the analog / digital converter 124 and the rotational speed of the internal combustion engine 36 over a time T that, for example, takes a few seconds can. The speed of the engine 36 may be supplied to the controller 120 from a motor controller 140 of the engine 36 via the bus 136. In the subsequent step 206, a frequency spectrum normalized to the rotational frequency of the internal combustion engine 36 is generated by means of the Fourier transformation device 126 and fed to the evaluation circuit 128. This identifies the ratio of the rotational frequency of the internal combustion engine 36 and the basic frequency of the detected signals of the vibration sensor 62 and possibly 62 'in step 208 in the detected frequency spectrum. The Grundffequenz corresponds to the rotational frequency of the cutterhead 26. Then follows the step 210, in which based on the identiüzierten in step 208 ratio of the rotational frequency of the internal combustion engine 36 and the Grundffequenz the detected signals of the vibration sensor 62 and possibly 62 'the configuration of the transmission 52 and of the belt drive, d. H. the dimensions of the pulleys 82 and 88 have been taken from the database 130. In this case, it is utilized that it is known which combinations of transmissions 52 and pulleys 82 and 88 available at the factory lead to what gear ratios of the drive train, which is composed of the gear 52 and the belt drive with the pulleys 82, 88 and the drive belt 84.
    In particular, no different combinations of gears 52 and pulleys 82, 88 are provided which result in the same transmission ratio of the drivetrain. The determined powertrain configuration may be displayed by the display device 134 upon a corresponding input by the operator. In addition, it may be used by the controller 138 to derive the speed of the cutterhead 26 from the speed of the engine 36 provided by the engine controller 140, which slip in the belt transmission may be neglected or accounted for, for example, based on the particular load on the engine 36 is also provided by the engine controller 140. Step 210 is followed by step 200 again.
    FIG. 6 shows a flow chart according to which the control device 120 proceeds to determine the number of chopping blades 54 of the chopper drum 26. After the start in step 300, a check is made in step 302 as to whether the chopper drum 26 is rotating without processing material being processed. This information can be determined as in step 202. If the result of step 302 is negative, step 302 again occurs. Otherwise, step 304 is followed by the control device 120 detecting the output signals of the analog / digital converter 124 over a time T, which may for example last a few seconds.
    In the subsequent step 306, a frequency spectrum normalized to the rotational frequency of the chopper drum 26 is generated by means of the Fourier transformation device 126 and fed to the evaluation circuit 128. This identifies in step 308 in the detected frequency spectrum the position (frequency in relation to the rotational frequency of the cutterhead 26) and the height (or included area) of the individual maximum of the signals detected
    Vibration sensor 62 and possibly 62 '. This is followed by step 310 where the data identified in step 308 is compared to database 130 to find out the number of chopping knives 54 that most closely matches the locations and sizes of the determined maxima. Specifically, the number of chopping blades 54 in each ring and the number of rings from the database 130 can be determined, and it can also be found if chopping blades 54 are missing or displaced inwardly to an inactive position on each or all of the rings. Furthermore, information regarding the width of the chopper drum 26 can be taken from the database 130.
    The determined number of chopping blades 54 may be displayed by the display 134 at step 312 upon a corresponding input by the operator. In addition, it is forwarded to the controller 138. The controller 138 requires the number of chopper knives 54 to achieve a cut length predetermined by the operator or crop detection sensor 142 (eg, working in the near infrared region and detecting the moisture of the crop) by correspondingly driving the hydraulic pump 102 and / or the hydraulic motor 112 , This is followed by step 312, in which the evaluation device 128 checks whether there is a fault, for example an asymmetrical or otherwise unacceptable arrangement and distribution of the chopping blades 54 on the cutterhead 26. If this is the case, step 316 follows in which via the display device 134 a warning is issued. In addition, in this case, the internal combustion engine 36 can be stopped automatically and / or the actuator 90 can be made to separate the clutch 78. Step 314 is followed by step 300 again.
