Description

[0001] Data processing system for an agricultural machine and method for controlling an agricultural machine

[0002] The invention relates to a data processing system for an agricultural machine for applying spray liquid according to the preamble of patent claim 1 and to a method for controlling an agricultural machine for applying spray liquid according to the preamble of patent claim 19.

[0003] The data processing systems used to apply spray liquid to agricultural land usually have a screen and an electronic processing unit, whereby the electronic processing unit can determine current application parameters.

[0004] Data processing systems are known in practice that offer a configurable application rate overview on the screen, in which at least one current application parameter is graphically displayed in an overview. However, the overview in the application rate overview only provides the operator with a rough overview of the current application situation. Until now, the operator has had to make settings or adjustments based on the overview in the application rate overview.

[0005] The object underlying the invention is therefore to provide the operator with additional detailed information on the current application situation during the application process, as required, and thus to enable the operator to intervene in the control system as required.

[0006] The object is achieved by a data processing system of the type mentioned at the outset, wherein a detailed application rate overview can be set on the screen of the data processing system according to the invention, in which overview current section-specific and / or nozzle-specific application rate parameters for one or more sections and / or for one or more nozzles of the agricultural machine are graphically displayed in a detailed representation. Determining the current application rate parameters can, for example, comprise calculating the current application rate parameters and / or retrieving and / or receiving the current application rate parameters. The application rate parameters can, for example, be retrieved and / or received by a control unit, in particular by a task controller. The section-specific and / or nozzle-specific application rate parameters can be graphically displayed on the screen.When applying the spray liquid based on application maps, it may happen, for example, that different application rate parameters need to be set across the sections or nozzles, for example due to locally increased yield potential or locally increased pest infestation. The sections and / or nozzles of the agricultural machine can be arranged next to one another along a transversely extending spray boom of the machine. The sections and / or nozzles can be distributed symmetrically or asymmetrically along the spray boom. The sections can have the same width or different widths. The nozzles can have the same spray cones and / or spray fans or different spray cones or spray fans. The respective sections can comprise one or more nozzles or one or more nozzle groups.The application rate parameter of a single section, which can include one or more nozzles, can be manipulated using a zoom function and a scroll function.

[0007] The data processing system according to the invention can also be used for an agricultural machine for sowing seed, in particular for a seed drill. In this case, the application rate parameters preferably relate to the amount of seed sown via the sowing coulters of the agricultural machine.

[0008] The data processing system according to the invention can also be used for an agricultural machine for spreading fertilizer, in particular for a fertilizer spreader. In this case, the application rate parameters preferably relate to the amount of fertilizer applied via fertilizer placement or discharge elements of the agricultural machine. In a preferred embodiment of the data processing system according to the invention, the current section-specific and / or nozzle-specific application rate parameters for the one or more sections and / or the one or more nozzles of the agricultural machine are displayed in the detailed view in a column display, with one or more columns assigned to each section and / or each nozzle.The current section- and / or nozzle-specific application rate parameters for the one or more sections and / or the one or more nozzles of the agricultural machine can alternatively be displayed in the detailed view using a bar display. The columns or bars preferably consist of one or more rows of pixels. The bar display can include a scale. The scale can automatically adjust to the application rate parameters to be displayed.

[0009] In a further preferred embodiment of the data processing system according to the invention, the at least one application rate parameter graphically displayed in the overview display is a current actual application rate. Alternatively or additionally, the one or more section- and / or nozzle-specific application rate parameters graphically displayed in the detailed display are current section- and / or nozzle-specific actual application rates. The actual application rates can be measured and / or calculated and / or estimated. The total application rate is measured, for example, in liters per minute using a flow meter. Using the driving speed and the current working width, the average actual application rate in liters per hectare can then be calculated.When using pulse width modulated valves, the distribution of the quantity along the spray boom can be calculated and / or estimated based on the set duty cycle or the set duty cycle of the valves.

[0010] Furthermore, a data processing system according to the invention is advantageous in which the electronic computing unit is configured to determine section-specific and / or nozzle-specific target application rate parameters, wherein the determined section-specific and / or nozzle-specific target application rate parameters for the one or more sections and / or the one or more nozzles of the agricultural machine are graphically displayed in the application rate detail view. Determining the section-specific and / or nozzle-specific target application rate parameters can, for example, comprise calculating the target application rate parameters and / or retrieving and / or receiving the target application rate parameters. The target application rate parameters can, for example, be retrieved and / or received by a control unit, in particular by a task controller.

[0011] In a further preferred embodiment of the data processing device according to the invention, the section- and / or nozzle-specific target application rate parameters for the one or more sections and / or the one or more nozzles of the agricultural machine are integrated in the detailed display into the bar display of the current section- and / or nozzle-specific actual application rate parameters for the one or more sections and / or the one or more nozzles of the agricultural machine. This integration provides a clear display, for example during cornering, of whether or when the limit for active ingredient dosing at the ends of the spray boom has been reached and how much the actual application rate parameter deviates from the target application rate parameter.

[0012] Furthermore, a data processing system according to the invention is advantageous in which a column assigned to a section or nozzle changes color when the current section- and / or nozzle-specific actual application rate parameter deviates from a section- and / or nozzle-specific target application rate parameter by more than a tolerance. The color change, for example, from green to red or from green to yellow, immediately indicates to the operator that the actual application rate parameter has left an acceptable range, allowing the operator to initiate appropriate measures to correct the actual application rate parameter.

[0013] The data processing system according to the invention is further advantageously developed in that one or more sections and / or one or more nozzles can be selected in the application rate detail view by touching the screen in one or more section- and / or nozzle-specific selection areas and / or by actuating one or more actuating elements of the data processing system to set a section- and / or nozzle-specific target application rate correction parameter that is higher in the control hierarchy than the section- and / or nozzle-specific target application rate parameter. The operator can set the target application rate correction parameter directly and / or via a target application rate correction factor, for example if the active ingredient dosage is to be adjusted in certain areas of the agricultural land, such as in areas with different fertilizer requirements or areas with different weed infestation.By touching the screen in several section- or nozzle-specific selection areas and / or by activating several control elements of the data processing system, several sections or nozzles can be selected. By touching the screen in a collective selection area and / or by activating a collective control element of the data processing system, all sections or nozzles can be selected. The selection area for setting the target quantity correction parameter is preferably located below the display area of ​​the column assigned to the section and / or nozzle in the column display.

[0014] In a further preferred embodiment of the data processing system according to the invention, the electronic processing unit is configured to use the set section-specific and / or nozzle-specific target rate correction parameter as the basis for a static or dynamic target rate correction. With static target rate correction, the set correction application rate is maintained regardless of a changing target rate. With dynamic target rate correction, the set correction application rate dynamically adapts to the changing target rate. With dynamic target rate correction, the correction application rate can be calculated, for example, by offsetting the changing target rate with a constant or variable correction factor.

[0015] Furthermore, a data processing system according to the invention is preferred in which the target quantity correction parameter of the one or more sections or nozzles selected for setting the target quantity correction parameter can be adjusted by touching the screen in the area of ​​at least one displayed icon and / or by actuating an actuating element of the data processing system. Preferably, the target quantity correction parameter of the one or more selected sections or nozzles can be increased by touching the screen in the area of ​​a first displayed icon and / or by actuating a first actuating element of the data processing system, and can be decreased by touching the screen in the area of ​​a second displayed icon and / or by actuating a second actuating element of the data processing system.When setting the target quantity correction parameter, the section- and / or nozzle-specific target application rate parameter preferably remains displayed, for example by a dashed line in the column assigned to the section or nozzle.

[0016] In a further preferred embodiment of the data processing system according to the invention, the setting of the target quantity correction parameter of the one or more sections or nozzles selected for setting the target quantity correction parameter can be canceled by touching the screen in the area of ​​at least one displayed pictogram and / or by actuating an actuating element of the data processing system, so that the setting of the section- and / or nozzle-specific target application rate parameter, which is lower in the control hierarchy, is initiated again. This cancels the override by touching the pictogram or by actuating the actuating element. Furthermore, the spray pressure of the spray liquid can be adjusted by touching the screen in the area of ​​at least one displayed pictogram and / or by actuating an actuating element of the data processing system.Preferably, the spray pressure of the spray liquid can be increased by touching the screen in the area of ​​a first displayed pictogram and / or by actuating a first actuating element of the data processing system and can be reduced by touching the screen in the area of ​​a second displayed pictogram and / or by actuating a second actuating element of the data processing system.

[0017] In another preferred embodiment of the data processing system according to the invention, the electronic processing unit is configured to determine current section-specific and / or nozzle-specific application parameters, wherein the determined current section-specific and / or nozzle-specific application parameters for a section and / or nozzle of the agricultural machine are graphically displayed in the overall application rate overview and / or in the application rate detail view. Determining the section-specific and / or nozzle-specific application parameters can, for example, comprise calculating the application parameters and / or retrieving and / or receiving the application parameters.The section- and / or nozzle-specific application parameters can include: the section- and / or nozzle-specific actual application rate; and / or the section- and / or nozzle-specific target application rate; and / or the deviation of the section- and / or nozzle-specific actual application rate from the section- and / or nozzle-specific target application rate; and / or the nozzle type installed on the section or currently selected; and / or a duty cycle range for pulse-width modulated valves of the agricultural machine suitable for the current application process; and / or the section- and / or nozzle-specific droplet spectrum; and / or the section- and / or nozzle-specific spray pressure.

[0018] A data processing system according to the invention is also advantageous in which the respective sections and / or nozzles can be selected in the application rate detail view by touching a screen in a section- and / or nozzle-specific selection area and / or by actuating an actuating element of the data processing system to display the section- and / or nozzle-specific application parameters. The current section- and / or nozzle-specific application parameters for a section and / or nozzle of the agricultural machine can be displayed in relation to section- and / or nozzle-specific application parameters of one or more sections or nozzles that are selected for setting a target rate correction parameter. The selection area for displaying the section- and / or nozzle-specific application parameters is preferably the display area of ​​the column assigned to the section in the column display.

[0019] A data processing system according to the invention is further preferred in which the section- and / or nozzle-specific application parameters are displayed in a parameter display area of ​​the screen in addition to the current section- and / or nozzle-specific actual application rate parameters and / or the section- and / or nozzle-specific target application rate parameters and / or the set section- and / or nozzle-specific target application rate correction parameters. The operator can switch between several section- and / or nozzle-specific application parameters by swiping across the parameter display area.

[0020] The data processing system according to the invention is further advantageously further developed in that the electronic processing unit is configured to determine a driving speed range suitable for the current application process. The determined driving speed range is graphically displayed in the overall application rate overview and / or in the application rate detail view in a speed display area of ​​the screen. Preferably, the current driving speed is also displayed in the overall application rate overview and / or in the

[0021] A detailed overview of the application rate is displayed in the speed display area of ​​the screen. When determining the appropriate driving speed range for the current application process, the electronic processing unit can consider whether to overdose or underdose in a borderline situation, depending on the settings.

[0022] In a further preferred embodiment of the data processing system according to the invention, the electronic processing unit is configured to determine operating information, in particular the current duty cycle of pulse-width modulated valves of the agricultural machine. Alternatively or additionally, the electronic processing unit is configured to determine a duty cycle range suitable for the current application process for the pulse-width modulated valves of the agricultural machine. The determined operating information and / or the determined duty cycle range are preferably displayed graphically in the overall application rate overview and / or in the application rate detail view in a duty cycle display area of ​​the screen.Determining the operating information or the duty cycle range can include calculating and / or retrieving and / or receiving the operating information or the duty cycle range. The duty cycle of a pulse-width modulated valve can also be referred to as the duty cycle of the pulse-width modulated valve. When negotiating tight curves, it may happen that the minimum permitted duty cycle is not low enough, or conversely, a 100% duty cycle is not sufficient as the maximum. As a result, the optimal driving speed when driving straight ahead may be a larger range, but this range becomes smaller when cornering, and a quantity error can only be maintained within an acceptable tolerance range for a specific driving speed range. A similar situation can arise when using an application map, according to which different application rates of spray liquid are to be applied along the spray boom.The greater the difference between the minimum and maximum duty cycle, the smaller the range of optimal driving speed.

[0023] The data processing system according to the invention is further advantageously developed in that a nozzle configuration overview can be set on the screen, in which the configuration of the nozzles and / or a target spray pressure for the spray liquid can be set. The operator can also add new nozzles and their properties via the nozzle configuration overview, so that the nozzles used on the agricultural machine can also be replaced with a different nozzle type.

[0024] In a further preferred embodiment of the data processing system according to the invention, one or more droplet size definition overviews, each assigned to a specific nozzle type, can be set on the screen. In these overviews, spray pressure limit values ​​for the droplet sizes that occur when using the respective nozzle type can be defined. The droplet size definition overviews can thus be used to store the pressure-dependent atomization properties of the nozzle type used, so that they can be taken into account when controlling the agricultural machine when applying spray liquid to the agricultural field.

[0025] Furthermore, a data processing system according to the invention is advantageous in which the electronic processing unit is configured to check the plausibility of the spray pressure limit values ​​defined in the one or more droplet size definition overviews for the droplet sizes that occur when using the respective nozzle type. The electronic processing unit can be configured to trigger the output of a warning message and / or refuse to save the spray pressure limit values ​​entered by the operator if the plausibility assessment is negative.

[0026] The object underlying the invention is further achieved by a method of the type mentioned above, wherein, within the scope of the method according to the invention, a detailed application rate view is set on the screen, in which the determined current section- and / or nozzle-specific application rate parameters for one or more sections and / or nozzles of the agricultural machine are graphically displayed in a detailed representation. The method according to the invention is preferably carried out using a data processing system according to one of the embodiments described above. With regard to the advantages and modifications of the method according to the invention, reference is therefore made to the advantages and modifications of the data processing system according to the invention.

[0027] Preferred embodiments of the invention are explained and described in more detail below with reference to the accompanying drawings.

[0052] Fig. 1 shows a data processing system 10 for an agricultural machine for applying spray liquid to agricultural land. The data processing system 10 is designed as an operator terminal and includes a touch-sensitive screen 12 and an electronic processing unit 14 configured to determine current application parameters. The current application parameters can be determined, for example, by calculating and / or retrieving and / or receiving the application parameters. The application parameters can be retrieved or received, for example, by a control unit 16 of the data processing system 10 acting as a task controller.

[0053] A total application rate overview can be set on screen 12 of the data processing system 10, in which a current application parameter is graphically displayed in an overview. Furthermore, a detailed application rate view can be set on screen 12, in which current section- and / or nozzle-specific application rate parameters for one or more sections and / or for one or more nozzles of the agricultural machine are graphically displayed in a detailed view.

[0054] Fig. 2 shows a data processing system in which the screen 12 is part of a standalone display device. The display device comprising the screen 12 can be, for example, a portable mobile phone. The display device comprising the screen 12 can be connected to a processing unit 14 of the data processing system 10 via a wired or wireless connection. The processing unit 14 can be connected to a control unit 16 of the data processing device 10 via a wired or wireless connection. The control unit 16 can be a task controller.

[0055] On screen 12, a total application rate overview and a detailed application rate view can be set. Figure 3 shows a total application rate overview 100. The overview display 102 shows several application rate parameters, such as the current application rate in [L / ha] and the current spray pressure in [bar]. Furthermore, the application rate across the entire boom width is shown graphically in a highly simplified manner.

[0056] To the right of the overview display 102 are the control panels 104, which can be selected by the operator to enter operating commands via a finger touch.

[0057] Fig. 4 shows a detailed application rate view 200, in which current section-specific application rate parameters 206a-206i, 208a-208i for several sections of the agricultural machine are graphically displayed in a detailed view 202. To the right of the detailed view 202 are again control panels 204, which can be selected by the operator to enter operating commands via a finger touch.

[0058] The current section-specific application rate parameters 206a-206i for the multiple sections of the agricultural machine are section-specific actual application rates and are displayed in a bar chart, with each section assigned a column. The bar chart includes a scale, which automatically adjusts to the application rate parameters 206a-206i to be displayed. The application rate parameters 208a-208i are current section-specific target application rates, with the section-specific target application rates being integrated into the bar chart of the current section-specific actual application rates 206a-206i for the multiple sections of the agricultural machine via a horizontal bar or a horizontal line.

[0059] In the application rate detail view 200, the operator can compare the actual application rates 206a-206i with the target application rates 208a-208i in order to be able to make a manual target rate correction on one or more sections if necessary.

[0060] To do so, the operator can select the selection areas 210, 210a-210i marked in Fig. 5 by touching the screen 12. The operator can set a target rate correction parameter 238 as follows: First, one or more sections of the agricultural machine must be selected by touching the selection area 210a-210i assigned to the respective section. By touching the selection area 210, all sections of the agricultural machine can also be selected. In Fig. 5, by touching the selection area 210i, the right-most section of the agricultural machine is selected. By touching the pictograms 214a, 214b in the area of ​​the control panels 204, the target rate correction parameter 238 can be set. By touching the pictogram 214a, the target application rate of the selected section is increased.By touching the pictogram 214b, the target application rate of the selected section is reduced.

[0061] By touching the pictogram 216, the target quantity correction can be canceled, so that the original target application rate 208i is restored. When a target quantity correction is active, the horizontal bar or horizontal line assigned to the target application rate 208i is displayed as a dashed line, so that the distance to the target quantity correction parameter 238 can be determined.

[0062] The individual columns of the column display also represent section-specific selection areas 212a-212i. By touching a column assigned to a section, section-specific application parameters are displayed in the application parameter overview 224. In Fig. 5, section number 6 is selected, and this is indicated to the operator via a triangle below the column assigned to the section. The application parameter overview 224 displays a section-specific application rate in liters per hectare, a deviation from a target application rate in percent, nozzle information, and a duty cycle range. The application parameter overview 226 also displays the current spray pressure and the droplet spectrum implemented at the prevailing spray pressure.

[0063] The operator can adjust the spray pressure by touching the pictograms 218a, 218b. The spray pressure can be increased by touching the pictogram 218a. The spray pressure can be decreased by touching the pictogram 218b. The spray pressure can be reset to the original target value by touching the pictogram 220. Fig. 6 shows a detailed view of the speed display area 222, also shown in Figs. 4 and 5. The electronic processing unit 14 of the data processing system is configured to determine a travel speed range suitable for the current application process. The determined travel speed range is displayed graphically in the application rate detail view 200 in the speed display area 222 of the screen 12. The current travel speed is also displayed in the speed display area 222 via a vertical bar.The position of the vertical bar allows the operator to conveniently determine whether the current driving speed is within the calculated appropriate driving speed range.

[0064] Fig. 7 shows an application overview 228 that can be set on the screen 12 of a data processing system 10 according to the invention. In the application overview 228, the operator is shown the target quantities for area spraying and band spraying as well as a reduced target quantity for a band width of 25 cm.

[0065] Fig. 8 shows an application overview 230 which can be displayed on the screen 12 of a data processing system 10 according to the invention, in which the operator is shown the nozzle type currently used, the set target injection pressure and the droplet spectrum resulting from the set target injection pressure.

[0066] Figure 9 shows a nozzle configuration overview 232, which the operator can use to configure multiple nozzles. In the illustrated nozzle configuration overview 232, one of four possible nozzles is configured, namely the nozzle labeled IDTA. The nozzle designation is located on a color-contrasting field. The field containing the nozzle designation "IDTA" can, for example, be highlighted in red. This color can represent an internationally standardized nozzle size. Nozzles of the same caliber have the same colors internationally.

[0067] By touching the screen 12 in an area assigned to a nozzle, the individual nozzle configuration view 234 shown in Fig. 10 is accessed. In the individual nozzle configuration view 234, a nozzle name can be assigned and a color or nozzle size can be assigned to the nozzle. In the view shown, the color red has the nominal size 04. Furthermore, the flow rate at 3 bar spray pressure must be specified. By touching the screen in an area assigned to the droplet size class, the operator accesses the droplet size definition overviews 236a, 236b, which are shown in Figs. 11 and 12.

[0068] In the droplet size definition overviews 236a, 236b, the operator can assign maximum pressure values ​​to the respective droplet size classes UC (ultra-coarse), XC (extremely coarse), VC (very coarse), C (coarse), M (medium), F (fine), VF (very fine), and XF (extremely fine). The pressure values ​​assigned by the operator are checked for plausibility by the computing unit 14 of the data processing system 10. If the plausibility check results in a negative result, for example, the entered maximum pressure values ​​can be refused storage and / or a warning can be issued.
