    “SYSTEM AND METHOD FOR MONITORING THE PRODUCTION OF WASTE FROM A HARVESTER”
    Background
    [001] The present description refers in general to a system and method for monitoring the production of waste from a combine.
    [002] In general, a harvester system processes agricultural crops, collects agricultural products from crops, and deposits waste from crops in an agricultural field as the harvester system passes through the agricultural field. Harvester systems typically include a cutter to cut waste into smaller pieces before depositing waste on the field, crop waste may fall into the agricultural field, thereby taking nutrients back to the agricultural field. The properties of the crop residue in the agricultural field (for example, size of the waste pieces, percentage of the agricultural field that is covered by the waste, thickness of the residue cover, and a uniformity of the scattering of the crop waste, etc.) can affect the amount of nutrients taken back to the agricultural field. However, if the properties are not good and / or the properties are not known, the yield of the harvest for a subsequent harvest may be reduced.
    Brief Description
    [003] In one embodiment, one or more machine-readable, non-transitory, tangible media that includes instructions that cause a processor to receive a signal indicating a residue cover on an agricultural field surface from a sensor, and the sensor is positioned behind a combine system with respect to the direction of travel. The instructions also cause the processor to determine the waste coverage on the agricultural field surface based on the signal, and the waste coverage includes the percentage of the agricultural field that is covered by the waste. Additionally, the instructions make the
    Petition 870190110735, of 10/30/2019, p. 14/40
    2/19 processor controls a waste control system based on waste coverage.
    [004] In another embodiment, a system for monitoring waste coverage on an agricultural field surface includes a controller that receives a signal indicating a waste coverage on an agricultural field surface from a sensor, and the sensor is positioned behind a combine system with respect to the direction of travel. The controller also determines the coverage of waste on the surface of the agricultural field based on the signal, and the coverage of waste includes the percentage of the agricultural field that is covered by the waste. In addition, the controller emits a control signal indicative of a set of settings for a waste control system based on waste coverage.
    [005] In an additional modality, a method for monitoring waste coverage on an agricultural field surface includes receiving a signal, via a controller, indicative of the waste coverage on the agricultural field surface from a sensor, and the sensor is positioned behind a combine system with respect to the direction of travel. The method also includes determining, through the controller, the coverage of waste on the surface of the agricultural field based on the sign, and the coverage of waste includes a percentage of the agricultural field that is covered by the waste and a uniformity value of the waste coverage . Additionally, the method includes generating, through the controller, a map of the waste coverage on the surface of the agricultural field. In addition, the method includes storing, through a storage device, the waste coverage map.

    Detailed Description
    [011] One or more specific modalities of the present description will be described below. In an effort to provide a concise description of these modalities, all features of an actual implementation may not be described in the specification. It should be considered that in the development of any real implementation, as in any engineering or design project, several implementation-specific decisions must be made to achieve the specific objectives of the developers, such as compliance with system-related and business-related restrictions, which may vary from one implementation to another. In addition, it must be considered that this development effort can be complex and time-consuming, but it would nevertheless be a routine task of design, manufacture and production for those skilled in the art who have the benefit of this description.
    [012] When introducing elements of various modalities of this description, articles a, one, o and said are intended to mean that there is one or more of the elements. The terms comprising, including and having are intended to be
    Petition 870190110735, of 10/30/2019, p. 16/40
    4/19 inclusive and mean that there may be other elements besides the listed elements. Any examples of operational parameters and / or environmental conditions are not exclusive to other parameters / conditions of the described modalities.
    [013] Turning now to the drawings, Figure 1 is a side view of a modality of a combine system 10 that travels in an agricultural field 12. The combine system 10 is configured to travel along a surface 14 of the field agricultural 12 in a travel direction 22. As harvester system 10 travels through agricultural field 12, a platform 16 arranged in front of harvester system 10 collects agricultural crops. The combine system 10 processes agricultural crops to separate a portion that is collected (e.g., agricultural product) from a portion that is taken back to the field (e.g., waste). The portion that is taken back to the field (for example, waste) is discharged by the combine system 10 into a waste spreader 18. Additionally, the harvest waste that is taken back to the field covers the field and can be used to return nutrients for agricultural field 12.
    [014] After the crop residues have been discharged back onto surface 14, a sensor assembly 20 monitors the residues. The sensor assembly 20 is arranged behind the combine system 10 with respect to travel direction 22, which allows the sensor assembly 20 to monitor the surface 14 behind the combine system 10. Although the sensor assembly 20 is coupled to a bar 21 that extends from the top of the harvester system 10 in the present embodiment, it should be noted that, in alternative embodiments, the sensor assembly can be coupled to the harvester system in another suitable way that allows the sensor assembly to monitor the surface behind the system combine harvester.
    [015] In certain embodiments, the combine system 10 includes a cutter that receives crop residues (for example, from a
    Petition 870190110735, of 10/30/2019, p. 17/40
    5/19 crop processing within the harvester system) and cuts crop residues into smaller pieces. The cutter may include a rotary shaft with threshing knives that cut the crop residues as the shaft rotates. The speed and / or position of the cutter can be adjusted to change the size and / or burst rate of the crop residue. For example, the cutter can be moved up, down, left, or right, and / or the cutter's rotation rate can be increased or decreased.
    [016] In certain embodiments, the waste spreader 18 can also be controlled to adjust the spread of waste across the surface 14. For example, the waste spreader 18 can be controlled to spread the waste substantially evenly across the surface. 14. The waste spreader 18 can be controlled to move up, down, left, or right, so that waste is deposited at a target location. The waste spreader 18 can be additionally controlled to increase or decrease the width of the waste spread. For example, an exhaust duct from the waste spreader 18 may expand or contract to provide a target dispersion of the crop residue. The combination of controlling the target and the discharge width of the waste spreader 18 can adjust the spread of the waste, thereby making the waste cover substantially uniform behind the harvester system 10.
    [017] Figure 2 is a schematic diagram of a modality of a waste coverage control system 24 that can be used within the combine system 10 of Figure 1. In the illustrated embodiment, a waste coverage control system 24 includes a control system 26 (e.g., mounted on the combine system 10), and control system 26 includes a first transceiver 28 configured to establish a wireless communication link with a second transceiver 30 from a base station 32. As will be noted, the
    Petition 870190110735, of 10/30/2019, p. 18/40
    6/19 first and second transceivers can operate in any suitable frequency range within the electromagnetic spectrum. For example, in certain embodiments, transceivers can transmit and receive radio waves within a frequency range of about 1 GHz to about 10 GHz. Additionally, the first and second transceivers can use any suitable communication protocol, such as a standard protocol (for example, Wi-Fi, Bluetooth, etc.) or a proprietary protocol.
    [018] In the illustrated embodiment, the control system 26 includes a spatial location device 34, which is mounted to the combine system 10 and configured to determine the position of the combine system 10. The spatial location device can include any system configured to determine the position of the combine system, such as a global positioning system (GPS), for example. In certain embodiments, the spatial location device 34 can be configured to determine the position of the combine system 10 with respect to a fixed point within the field (for example, by means of a fixed radio transceiver). Accordingly, the spatial location device 34 can be configured to determine the position of the combine system 10 with respect to a fixed global coordinate system (for example, via GPS) or a fixed local coordinate system. In certain embodiments, the first transceiver 28 is configured to transmit a signal indicative of the position of the combine system 10 to the transceiver 30 of the base station 32.
    [019] Additionally, the combine system 10 includes the sensor set 20. The sensor set 20 is configured to facilitate the determination of the residue coverage on the surface of the agricultural field. In certain embodiments, the sensor assembly may include one or more sensors (for example, image sensor (s) (for example, camera (s) 33), radar sensor (s), terahertz sensor (s), sensor ( s) of

    7/19 infrared, ultrasonic sensor (s), capacitance sensor (s), light variation and detection sensor (LiDAR), etc.), each configured to monitor the residue coverage on the surface behind the system of harvester with respect to the direction of travel. In addition, the sensor array may include an illumination array 31 (e.g., an LED light, a halogen light, etc.) that provides light for the images captured by the image sensor (s). The lighting set can reduce the shadows cast by an element of the harvester system structure, the sensor assembly, clouds in the sky, etc. The use of the lighting set can provide more consistent lighting for the image sensor (s), which can increase the accuracy of the data produced by the sensor set 20. In certain embodiments, the sensor set may include a combination different sensors and the lighting set can be configured to provide light in different spectra of the electromagnetic spectrum. For example, the lighting array can provide illumination in the infrared spectrum for an infrared sensor. In addition, the sensor assembly 20 may include one or more sensors (for example, a weather vane, an anemometer, or both) that are configured to monitor the speed and direction of the wind. As discussed in detail below, waste coverage may include the percentage of the surface covered by the waste, the spread of the waste, the uniformity of the waste, the thickness of the waste, or any combination thereof.
    [020] In certain modalities, a controller 46 is an electronic controller having an electrical circuit configured to process data from transceiver 28, the spatial location device 34, the sensor set 20, or a combination thereof, among other system components harvester 10. In the illustrated embodiment, controller 46 includes a processor, such as the illustrated microprocessor 48, and a memory device 50.

    8/19 suitable. Processor 48 can be used to run software, such as software to control combine system 10, and so on. In addition, processor 48 may include multiple microprocessors, one or more "general purpose" microprocessors, one or more special purpose microprocessors, and / or one or more application specific integrated circuits (ASICS), or some combination thereof. For example, processor 48 may include one or more processors with a reduced instruction set (RISC).
    [021] Memory device 50 may include volatile memory, such as random access memory (RAM), and / or non-volatile memory, such as ROM. The memory device 50 can store a variety of information and can be used for various purposes. For example, memory device 50 can store computer executable instructions (for example, firmware or software) for processor 48 to execute, as well as instructions for controlling combine system 10. The storage device (s) ( for example, non-volatile storage) may include read-only memory (ROM), flash memory, a hard drive, or any other suitable solid-state or magnetic or optical storage medium, or a combination thereof. The storage device (s) can store data (for example, waste coverage maps, harvest settings, etc.), instructions (for example, software or firmware to control the combine system, etc.), and any other suitable data.
    [022] Control system 26 includes a waste control system 44 configured to control various parameters of the combine system 10. For example, in certain embodiments, the combine control system 44 can be configured to instruct controller 46 ( for example, via a communication link, such as a CAN bus or ISOBIIS) to adjust a cutter 38 or spreader 18 of the combine system 10. By way of example, the combine control system 44 can instruct the controller 46 to change one
    Petition 870190110735, of 10/30/2019, p. 21/40
    9/19 orientation / position 40 of cutter 38 (for example, up, down, left, or right), speed 42 of cutter 38, an orientation 44 of spreader 18 (for example, up, downwards, to the left, or to the right), a spreading element 45 of the spreader 18 (for example, it expands or contracts), or any combination thereof.
    [023] In the illustrated embodiment, the combine system 10 includes a user interface 60 coupled in communication mode to controller 46. User interface 60 is configured to present data from the combine system to an operator (for example, data associated with harvester system operation). User interface 60 is also configured to allow an operator to control certain functions of the combine system (for example, starting and stopping the combine system, etc.). In the illustrated embodiment, user interface 60 includes a screen 62 configured to present information to the operator, such as the position of the combine system 10 within the field, the speed of the combine system 10, the path of the combine system 10, the residue cover behind the harvester system 10, images or video from the sensor set 20, among other data.
    [024] As previously discussed, control system 26 is configured to communicate with base station 32 via transceivers 28 and 30. In the illustrated embodiment, the base station includes a controller 68 coupled in communication mode to the transceiver from base station 30. Controller 68 can be configured to issue commands and / or data to the combine system 10. For example, as discussed in detail below, controller 68 can be configured to perform at least some of the same operations as controller 46.
    [025] In certain embodiments, controller 68 is an electronic controller having an electrical circuit configured to process data from certain components of base station 32 (for example, transceiver 30).
    Petition 870190110735, of 10/30/2019, p. 22/40
    10/19
    In the illustrated embodiment, the controller 68 includes a processor, such as the illustrated microprocessor 70, and a memory device 72. The processor 68 can be used to run software, such as software to provide commands and / or data to the controller system. of combine 46, and so on. In addition, processor 48 may include multiple microprocessors, one or more "general purpose" microprocessors, one or more special purpose microprocessors, and / or one or more application specific integrated circuits (ASICS), or some combination thereof. For example, processor 70 may include one or more reduced instruction set (RISC) processors. The memory device 72 may include a volatile memory, such as random access memory (RAM), and / or a non-volatile memory, such as ROM. The memory device 72 can store a variety of information and can be used for various purposes. For example, memory device 72 can store computer executable instructions (e.g., firmware or software) for processor 70 to execute, such as instructions for providing commands and / or data to the combine controller system 46.
    [026] In the illustrated embodiment, base station 32 includes a user interface 74 coupled in communication mode to controller 68. User interface 74 is configured to present data from the combine system to an operator (for example, data associated with the operation of the combine system). User interface 74 is also configured to allow an operator to control certain functions of the combine system (for example, starting and stopping the combine system, etc.). In the illustrated embodiment, the user interface includes a screen 76 configured to present information to the operator, such as the position of the combine system 10 within the field, the speed of the combine system, the path of the combine system, debris behind the combine system, images or video from the sensor assembly 20
    Petition 870190110735, of 10/30/2019, p. 23/40
    11/19 among other data.
    [027] In the illustrated embodiment, base station 32 includes a storage device 78 coupled in communication mode to controller 68. Storage device 78 (e.g., non-volatile storage) may include read-only memory (ROM), flash memory, a hard drive, or any other suitable solid-state or magnetic or optical storage medium, or a combination thereof. The storage device (s) can store data (for example, waste coverage maps, etc.), instructions (for example, software or firmware to control the combine system, etc.), and any other data appropriate. For example, controller 46 or controller 68 can receive data from sensor assembly 20 and spatial location device 34. From said data, controller 46 or controller 68 can create a map of the waste coverage in the field agricultural. The map can include data on the location and distribution of waste coverage in the agricultural field.
    [028] Although the control system 26 of the waste coverage control system 24 includes controller 46 in the illustrated mode, it should be noted that in alternative modalities, control system 26 may include controller 68. For example, in certain modalities, certain functions of control system 26 can be distributed between controller 46 and controller 68. In additional modalities, controller 68 can perform a substantial portion of the functions of control system 26. For example, in certain modalities, the transceiver 28 can send signals indicating the coverage of residues to transceiver 30. In said modalities, transceiver 30 can emit signals corresponding to controller 68, and controller 68 can construct a map of coverage of residues and determine a control action based on waste coverage and issue a signal indicating the control action. For example, the controller
    Petition 870190110735, of 10/30/2019, p. 24/40
    12/19 can issue instructions to controller 46 (for example, via transceivers 28 and 30), instructing the waste control system 44 to change an orientation / position 40 of cutter 38 (for example, up, down , to the left, or to the right), the speed 42 of the cutter 38, an orientation 44 of the spreader 18 (for example, up, down, left, or right), a spreading element 45 of the spreader 18 (for example, expand or contract), or any combination thereof.
    [029] Figure 3 is a block diagram of a modality of the control system 26 that can be used within a waste coverage control system of Figure 2. In the illustrated modality, the control system 26 includes controller 46 However, as previously discussed, the control system may include the base station controller (for example, alone or in combination with controller 46). As illustrated, controller 46 receives a signal 80 indicative of an image of the agricultural field surface. Signal 80 is received from the sensor assembly, which is configured to monitor the surface for collecting images. In certain modalities, the sensor set can include sensors, whose data emitted is in different image formats, or can be converted into images. Controller 46 determines an emitted signal 82 indicative of surface residue coverage based on signal 80. The controller can determine residue coverage 82 by comparing differences in color. For example, the waste may be a different color from the underlying soil of the agricultural field, or the waste may be a softer color than that of the soil. Controller 46 can detect said differences and determine which portions of the surface image include waste and which portions of the surface image include soil. From that determination, controller 46 can determine various properties of the waste, which include what percentage of the surface is covered by the waste, the average size of the waste, or the uniformity of the spreading of the waste (ie
    Petition 870190110735, of 10/30/2019, p. 25/40
    13/19 is, how uniform the waste is distributed in the image).
    [030] In the illustrated mode, controller 46 also receives a signal 84 indicative of the combine's position. Additionally, in the illustrated embodiment, controller 46 receives a signal 86 indicative of the speed of the combine. In certain embodiments, signal 84 and signal 86 are received from the spatial location device, which is configured to determine the location and rate of change of the location (i.e., speed and acceleration) of the combine system. Controller 46 is configured to use a surface image signal 80, the combine position signal 84, and the combine speed signal 86 to create an emitted signal 88 indicative of the agricultural field waste coverage map. The signal emitted 88 can be displayed in real time to an operator (for example, via the combine system user interface or base station). In addition, the emitted signal 88 can also be stored in the storage device. In addition, the waste coverage map can be used to control subsequent tillage and / or seeding / planting operations. For example, the waste coverage map can be used during sowing / planting operations to control application rate and / or seed spacing, and / or the waste coverage map can be used during tillage operations to control the depth of penetration of tillage tools. In addition, the waste coverage map can be used to determine a target crop grade for each section of the agricultural field. In addition, the waste coverage map can be used to determine the fertilizer distribution for each section of the agricultural field.
    [031] In the illustrated mode, controller 46 receives a signal 94 indicative of wind speed and wind direction. As discussed above, wind speed and wind direction can be monitored and a signal can be emitted by the
    Petition 870190110735, of 10/30/2019, p. 26/40
    14/19 sensor set for controller 46. As discussed above, the signal emitted from the waste cover 82 and the signal emitted from the waste map 88 can be displayed to an operator (for example, on the combine user interface screen or on the base station user interface screen). In turn, the operator can manually adjust the waste control system settings to control the waste outlet. In other modalities, the controller can determine the settings of the waste control system and emit a signal emitted 92 indicating the settings of the waste control system. For example, waste control system settings can include speed and orientation / position for the cutter, and an orientation and spread of the waste spreader. As discussed above, these configurations can adjust the spread and coverage of debris across the surface. In still other embodiments, the controller can determine the waste control system based on the wind speed and direction signal 94 and a signal emitted from the waste cover 82 to create the signal emitted from the waste control system settings 92. The signal emitted from the waste control system 92 settings can be emitted substantially continuously (for example, at a frequency of one second or less), a signal emitted from the waste cover 92 can be emitted in time intervals, or the controller it can emit the signal emitted from the waste control system settings 92 after a threshold value has been reached. For example, a threshold value can be assigned to each of the waste coverage properties (for example, what percentage of the surface is covered by the waste, the average size of the waste pieces, the uniformity of the waste spreading (that is, the how uniform the waste is distributed in the image), the thickness of the waste, the position of the waste in relation to the combine, the size of the waste pieces). After the threshold value has been crossed for any combination of the waste coverage properties, the controller can emit the signal emitted from the
    Petition 870190110735, of 10/30/2019, p. 27/40
    15/19 waste control system settings 92.
    [032] For example, if a signal emitted from the waste cover 82 indicates that the waste is not evenly spread on the surface, the signal emitted from the waste control system settings 92 can adjust the position of the cutter or spreader so that the portion of the surface that receives less pieces of waste receives more pieces of waste. For example, if the left side of the surface is receiving fewer pieces of waste, the position of the cutter and / or spreader can be adjusted to the left to provide more pieces of waste to the left. Alternatively, if the waste pieces are determined to be very large, the speed of the cutter may increase so that the size of the waste pieces is reduced. Alternatively, if the spread of waste is very narrow, the spreader opening can be expanded to allow greater spread of waste. Alternatively, if the waste is deposited too close to the combine, the spreader's orientation can be adjusted upwards. Alternatively, if the thickness of the waste is too high, the amount of waste deposited may increase.
    [033] Figure 4 is a flow chart of a modality of a process 100 for controlling the settings of the waste control system of the harvester system 10. Process 100 increases the uniformity of waste coverage across the surface of the agricultural field. . Although process 100 below includes a number of operations that can be performed, it should be noted that process 100 can be performed in a variety of suitable orders. All operations of process 100 may not be performed. In addition, all operations of process 100 may be performed by the combine controller 46, the base station controller 68, or a combination thereof. It should be noted that the combine controller 46 can perform all functions of the base station controller 68, and the base station controller 68 can perform all functions.
    Petition 870190110735, of 10/30/2019, p. 28/40
    16/19 combine controller functions 46.
    [034] The initial settings of the waste control system of the waste control system can be adjusted (block 102). For example, the operator can adjust an initial cutter orientation / position and / or speed, an initial spreader orientation and / or width, or a combination thereof. In certain modalities, the initial operating parameters are based on previous agricultural operations from a previous season or from saved initial configurations.
    [035] Then, data acquisition can be conducted (block 104). For example, the sensor set may include one or more sensors (for example, image sensor (s) (for example, camera (s)), radar sensor (s), terahertz sensor (s), sensor (s) infrared, ultrasonic sensor (s), capacitance sensor (s), LiDAR sensor (s), etc.), each configured to monitor the residue coverage on the surface behind the harvester system with respect to the direction of travel. In addition, the sensor array may include a lighting array (for example, an LED light, a halogen light, etc.) that provides light for the images captured by the image sensor (s). The lighting set can reduce the shadows cast by an element of the harvester system structure, the sensor assembly, clouds in the sky, etc. The use of the lighting set can provide more consistent lighting for the image sensor (s), which can increase the accuracy of the data produced by the sensor set 20.
    [036] Next, the waste coverage and / or the waste coverage map is determined (block 106). After conducting the data acquisition, the controller can analyze the data to determine the residue coverage on the surface of the agricultural field. As discussed above, waste coverage can include properties related to the percentage of the surface covered by the waste, the average size of the waste pieces, the uniformity of the waste spreading
    Petition 870190110735, of 10/30/2019, p. 29/40
    17/19 (that is, how uniformly the waste is distributed in the image), the thickness of the waste (that is, the amount of waste deposited on the surface), the position of the waste in relation to the combine, or a combination thereof, among other waste properties. Additionally, from the data, the controller can create a map of the waste coverage in the agricultural field. The map can include data on the location and distribution of waste coverage in the agricultural field.
    [037] The waste coverage is then assessed (block 108). For example, the controller can assess whether one or more of the waste coverage properties are within a specified range. In certain embodiments, the range may include a minimum threshold value, a maximum threshold value, or a combination thereof. For example, the range may include a minimum threshold value that corresponds to the percentage of the surface that is covered by the waste (that is, 5%, 10%, 20%, 30%, 40%, 50%), the average size of the pieces of waste (ie, 1 cm (“cm”), 2 cm, 3 cm, 4 cm, 5 cm), the uniformity of the spreading of the waste, the thickness of the waste, or the position of the waste in relation to the combine. In addition, the range may include a maximum threshold value that corresponds to the percentage of the surface that is covered by the waste (ie 40%, 50%, 60%, 70%, 80%, 90%), the average size of the pieces of residue (ie, 3 cm, 5 cm, 7 cm, 10 cm, 15 cm), the uniformity of the spreading of the waste, the thickness of the waste, or the position of the waste in relation to the combine.
    [038] If the waste coverage is within the specified range, the controller can issue a signal to the waste coverage system indicative of instructions for maintaining (block 110) the initial operating parameter. Subsequently, the sensor assembly can continue to conduct (block 104) data acquisition as the harvester system moves through the agricultural field.
    [039] However, if the waste coverage is outside the specified range, the controller can emit (block 112) a signal to the waste control system
    Petition 870190110735, of 10/30/2019, p. 30/40
    18/19 indicative of instructions for setting the operating parameter from the initial operating parameter to an adjusted operating parameter. The adjusted operating parameter can be determined by referencing a data table that includes changes in the operating parameter values correlated to the desired changes in waste coverage properties. For example, if a 10% increase in the percentage of the surface covered by the waste is desired, the data table may include changes in operating parameter values that correspond to a 10% increase in the percentage of the surface covered by the waste. Subsequently, the sensor assembly can conduct (block 104) acquisition of additional data. Therefore, the waste coverage can be monitored and adjusted during the harvest.
    [040] In addition, the data that was acquired in block 104 can also be stored (block 114) in the storage device. Said data can be stored so that a map of the waste coverage within the agricultural field is created. The waste coverage map can be used to control subsequent tillage and / or seeding / planting operations. For example, the waste coverage map can be used during sowing / planting operations to control the application rate and / or seed spacing, and / or the waste coverage map can be used during tillage operations to control the depth of penetration of tillage tools. Additionally, the waste coverage map can be used to determine the target crop grade for each section of the agricultural field. In addition, the waste coverage map can be used to determine the fertilizer distribution for each section of the agricultural field.
    [041] Although only certain features of the description have been illustrated and described here, many modifications and changes will occur for those
