The present disclosure generally relates to agricultural implements and, more particularly, to systems and methods for controlling the operation of an agricultural implement.
It is well known that, to attain the best agricultural performance from a field, a farmer must cultivate the soil, typically through a tillage operation. Modern farmers perform tillage operations by pulling a tillage implement behind an agricultural work vehicle, such as a tractor. In general, tillage implements include ground-engaging tools, such as shanks, disks, and/or the like, supported on its frame. Each ground-engaging tool, in turn, is configured to be moved relative to the soil within the field as the tillage implement travels across the field. Such movement of the ground-engaging tools loosens and/or otherwise agitates the soil to prepare the field for subsequent planting operations.
Upon completion of the tillage operation, it is generally desirable that the residue pieces remaining on the field surface be of a given length to maintain the productivity potential of the soil. In this respect, systems for controlling the operation of an agricultural implement such that the residue pieces remaining on the field surface are of the given length have been developed. While such systems work well, further improvements are needed.
Accordingly, an improved system and method for controlling the operation of an agricultural implement would be welcomed in the technology.
Aspects and advantages of the technology will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the technology.
In one aspect, the present subject matter is directed to an agricultural implement including a frame and a ground-engaging tool supported on the frame, with the ground-engaging tool configured to perform an operation on a field as the agricultural implement travels across the field.

In this respect, the computing system configured to identify a plurality of residue pieces present within the portion of the field based on the image data generated by the imaging device. Furthermore, the computing system is configured to determine a number of residue pieces of the identified plurality of residue pieces having a length within a first length range. Additionally, the computing system is configured to determine a number of residue pieces of the identified plurality of residue pieces having a length within a second length range, with the second length range being different from the first length range. Moreover, the computing system is configured to determine a characteristic length range for the portion of the field, with the characteristic length range corresponding to one of the first length range or the second length range having the greatest number of residue pieces associated therewith. In addition, the computing system is configured to control an operating parameter of the ground-engaging tool based on the determined characteristic length range.

These and other features, aspects and advantages of the present technology will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the technology and, together with the description, serve to explain the principles of the technology.
A full and enabling disclosure of the present technology, including the best mode thereof, directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended figures, in which:
Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present technology.
Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
In general, the present subject matter is directed to a system and a method for controlling the operation of an agricultural implement. Specifically, in several embodiments, a computing system of the disclosed system is configured to receive image data depicting a portion of the field across which the agricultural implement is traveling (e.g., to perform an agricultural operation thereon). Furthermore, the computing system is configured to identify a plurality of residue pieces present within the portion of the field based on the received image data. In addition, the computing system is configured to determine the number of identified residue pieces having a length within a first length range and the number of identified residue pieces having a length within a different, second length range. Moreover, the computing system is configured to determine a characteristic length range for the imaged portion of the field. The characteristic length range, in turn, corresponds to the first length range or the second length range having the greatest number of residue pieces associated therewith.
Additionally, in several embodiments, the computing system is configured to control one or more operating parameter(s) of a ground-engaging tool(s) of the agricultural implement based on the determined characteristic length range. Such operating parameter(s) may include the position(s) of the ground-engaging tool(s) relative to the implement frame, the penetration depth(s) of the ground-engaging tool(s), and/or the force(s) being applied to the ground-engaging tool(s). For example, in some embodiments, the computing system may control an angle(s) of a disk gang(s) of the agricultural implement relative to the frame based on the determined characteristic length range. Specifically, in such an embodiment, the computing system may initiate an increase in the angle(s) of the disk gang(s) relative to the frame when the characteristic length range changes from a first or smaller length range to a second or larger length range. Conversely, in such an embodiment, the computing system may initiate a decrease in the angle(s) of the disk gang(s) relative to the frame when the characteristic length range changes from the second or larger length range to the first or smaller length range.
Controlling an operating parameter(s) of the ground-engaging tool(s) of the agricultural implement based on the characteristic length range for the residue pieces present within the field improves the operation of the agricultural implement. More specifically, to leave residue pieces on the field surface having a given length after completion of an agricultural operation (e.g., a tillage operation), it is generally necessary to adjust the operating parameter(s) of the agricultural implement based on the lengths of the residue pieces present within the field prior to the operation. Because there can be a variety of lengths of residue pieces present on a portion of the field, some conventional systems use the average length of residue pieces or the range of lengths to control the implement operating parameter(s). However, in many instances, the lengths of the residue pieces may be skewed toward one end of the range. For example, a portion of the field may have many long residue pieces, with a few short pieces. Alternatively, the portion of the field may have many short residue pieces, with a few long pieces. In this respect, the average length and the length range of the residue pieces for a portion of the field may not provide an accurate indication of the typical lengths of the residue pieces present within that portion of the field. As described above, the characteristic length range corresponds to the particular residue piece length range having the greatest number of residue pieces associated therewith. Thus, by controlling the operating parameter(s) of the ground-engaging tool(s) based on the particular residue piece length range having the greatest number of residue pieces associated therewith, the operation of the agricultural implement can be tailored to the residue length range most prevalent within the field. This, in turn, results in the lengths of residue pieces remaining on the field surface upon completion of the agricultural operation more closely corresponding to the given length.

In general, the imaging device(s) 104 may correspond to any suitable sensing devices configured to generate image data or image-like data depicting the surface profile of the field. Specifically, in several embodiments, the imaging device(s) 104 may correspond to a suitable camera(s) configured to capture images of the soil surface of the field present within the field of view 106, thereby allowing the lengths of the residue pieces present on the surface of the field to be determined by analyzing the content of each image. For instance, in a particular embodiment, each imaging device(s) 104 may correspond to a stereographic camera(s) having two or more lenses with a separate image sensor for each lens to allow the cameras to capture stereographic or three-dimensional images. Alternatively, the imaging device(s) 104 may correspond to any other suitable devices for generating image data or image-like data, such as a monocular camera(s), a LiDAR device(s), a RADAR device(s), and/or the like.

For example, in the illustrated embodiment, an imaging device 104 is mounted on the forward end of the work vehicle 10. However, in alternative embodiments, an imaging device(s) 104 may be mounted at any other suitable location(s), such as at the forward end of the carriage frame assembly 30 or the forward frame 42 of the agricultural implement 12.
Additionally, in the illustrated embodiment, a single imaging device 104 is in operative association with the work vehicle 10. However, in alternative embodiments, multiple imaging devices 104 may be in operative association with the work vehicle 10 and/or the agricultural implement 12.

Moreover, the system 100 includes a computing system 112 communicatively coupled to one or more components of the work vehicle 10, the agricultural implement 12, and/or the system 100 to allow the operation of such components to be electronically or automatically controlled by the computing system 112. For instance, the computing system 112 may be communicatively coupled to the imaging device(s) 104 via a communicative link 114. As such, the computing system 112 may be configured to receive image data from the imaging device(s) 104 that is indicative of the residue present within the field across which the vehicle/implement 10/12 is traveling. Furthermore, the computing system 112 may be communicatively coupled to the disk gang actuator(s) 110 via the communicative link 114. In this respect, the computing system 112 may be configured to control the operation of the disk gang actuator(s) 110 to adjust the angle of the disk gang(s) 48 relative to the carriage frame 30. In addition, the computing system 112 may be communicatively coupled to any other suitable components of the work vehicle 10, the agricultural implement 12, and/or the system 100. For example, the computing system 112 may be communicatively coupled to the actuators 56, 58, 60 of the agricultural implement 12 via the communicative link 114.
In general, the computing system 112 may comprise one or more processor-based devices, such as a given controller or computing device or any suitable combination of controllers or computing devices. Thus, in several embodiments, the computing system 112 may include one or more processor(s) 116 and associated memory device(s) 118 configured to perform a variety of computer-implemented functions. As used herein, the term “processor” refers not only to integrated circuits referred to in the art as being included in a computer, but also refers to a controller, a microcontroller, a microcomputer, a programmable logic circuit (PLC), an application specific integrated circuit, and other programmable circuits. Additionally, the memory device(s) 118 of the computing system 112 may generally comprise memory element(s) including, but not limited to, a computer readable medium (e.g., random access memory RAM)), a computer readable non-volatile medium (e.g., a flash memory), a floppy disk, a compact disk-read only memory (CD-ROM), a magneto-optical disk (MOD), a digital versatile disk (DVD) and/or other suitable memory elements. Such memory device(s) 118 may generally be configured to store suitable computer-readable instructions that, when implemented by the processor(s) 116, configure the computing system 112 to perform various computer-implemented functions, such as one or more aspects of the methods and algorithms that will be described herein.

As shown, at (202), the control logic 200 includes receiving image data depicting a portion of a field across which an agricultural implement is traveling. Specifically, as mentioned above, in several embodiments, the computing system 112 is communicatively coupled to the imaging device(s) 104 via the communicative link 114. In this respect, as the agricultural implement 12 travels across the field to perform an agricultural operation (e.g., a tillage operation) thereon, the computing system 112 may receive image data from the imaging device(s) 104. Such image data, in turn, depicts the residue pieces present on the surface of a portion of the field.
Furthermore, at (204), the control logic 200 includes identifying, with the computing system, a plurality of residue pieces present within the portion of the field based on the received image data. Specifically, in several embodiments, the computing system 112 is configured to analyze the image data received at (202) to identify a plurality of residue pieces present within the portion of the field depicted in the received image data. For example, the computing system 112 may use any suitable image processing algorithms or techniques to identify the residue pieces, such as color-based image processing algorithms, texture-based image processing algorithms, and/or the like.
Additionally, at (206), the control logic 200 includes determining the lengths of the identified plurality of residue pieces. Specifically, in several embodiments, the computing system 112 is configured to analyze each of the plurality of residue pieces identified at (204) to determine its length. As used herein, the length of a residue piece corresponds to its longest dimension.
Moreover, at (208), the control logic 200 includes determining, with the computing system, the number of identified residue pieces having a length within a first length range. Specifically, in several embodiments, the computing system 112 is configured to analyze the lengths of the residue pieces determined at (206) to determine the number of identified residue pieces having a length within a first length range.
In addition, at (210), the control logic 200 includes determining the number of identified residue pieces having a length within a second length range. Specifically, in several embodiments, the computing system 112 is configured to analyze the lengths of the residue pieces determined at (206) to determine the number of identified residue pieces having a length within a second length range. In general, the second length range is different from the first length range. For example, the first length range may correspond to a small length range and the second length range may correspond to a large length range. In one embodiment, the first and second length ranges do not overlap.
The control logic 200 is described herein in the context of two length ranges. However, in alternative embodiments, the lengths determined at (206) may be placed into any suitable number of length ranges, such as three length ranges (e.g., small, medium, and large length ranges) or four or more length ranges.
Furthermore, at (212), the control logic 200 includes determining a characteristic length range for the portion of the field. The characteristic length range, in turn, corresponds to the first or second length range having the greatest number of residue pieces associated therewith. As such, the computing system 112 is configured to determine a characteristic length range for the portion of the field based on the number of residue pieces having lengths within the first length range and the number of residue pieces having lengths within the second length range. Specifically, the computing system 112 determines which of the first and second length ranges has the most residue pieces with lengths falling therein and assigns that length range as the characteristic length range. For example, when more residue pieces have lengths falling within the first length range than the second length range, the computing system 112 determines that the first length range is characteristic length range. Conversely, when more residue pieces have lengths falling within the second length range than the first length range, the computing system 112 determines that the second length range is characteristic length range.
As will be described below, one or more operating parameters of the ground-engaging tool(s) of the agricultural implement 12 are controlled based on the characteristic length range determined at (212). Such operating parameter(s), in turn, may include the positioning of the ground-engaging tool(s) relative to the implement frame, the penetration depth(s) of the ground-engaging tool(s), and/or the force(s) being applied to the ground-engaging tool(s) of the agricultural implement 12. Moreover, the operating parameter(s) of any suitable ground-engaging tool(s) of the agricultural implement 12 may be controlled based on the characteristic length range determined at (212). In one embodiment, the computing system 112 may control the operation of the actuators 56 to adjust the relative positioning of, the penetration depth of, and/or the force being applied to the disks 42 of the agricultural implement 12. In another embodiment, the computing system 112 may control the operation of the actuators 60 to adjust the relative positioning of, the penetration depth of, and/or the force being applied to the leveling blades 52 of the agricultural implement 12. In further embodiments, the computing system 112 may control the operation of the actuators 58 and/or the disk gang actuator(s) 110 to adjust the relative positioning of, the penetration depth of, and/or the force being applied to the disk gangs 48 of the agricultural implement 12.
For example, as will be described below, in a particular embodiment, the computing system 112 may control the operation of the disk gang actuator(s) 110 to adjust the angle(s) of the disk gang(s) 48 relative to the carriage frame 30.

Additionally, at (216), the control logic 200 includes initiating an increase in the angle of a disk gang of the agricultural implement relative to a frame of the agricultural implement. More specifically, when the current characteristic length range is the second length range and the previous characteristic range is the first length range, the typical length range of the reside pieces present within the field has increased. As such, it is necessary to increase the disk gang angles (e.g., the disk gang angles 272 in
Conversely, at (218), the control logic 200 includes determining when the characteristic length range changes from the second length range to the first length range. As mentioned above, in several embodiments, the second length range corresponds to greater residue lengths than the first length range. In such embodiments, the computing system 112 is configured to compare the characteristic length range determined at (212) for the current portion of the field to the determined characteristic length range for the previous portion of the field. When the current characteristic length range is the first length range and the previous characteristic length range is the second length range, the control logic 200 proceeds to (220). Alternatively, when the current and previous characteristic length ranges are the same, the control logic 200 returns to (202).
Moreover, at (220), the control logic 200 includes initiating a decrease in the angle of the disk gang relative to the frame of the agricultural implement. More specifically, when the current characteristic length range is the first length range and the previous characteristic range is the second length range, the typical length range of the residue pieces present within the field has decreased. As such, it is necessary to decrease the disk gang angles (e.g., the disk gang angles 272 in
For example, in one embodiment, the lengths of each identified residue piece may be placed within one of a small length range, a medium length range, or a large length range. In this respect, when the characteristic length range for the current portion of the field corresponds to the small length range, the disk gang angle may be about zero degrees. Moreover, when the characteristic length range for the current portion of the field corresponds to the medium length range, the disk gang angle may be about nine degrees. In addition, when the characteristic length range for the current portion of the field corresponds to the large length range, the disk gang angle may be eighteen degrees. However, in alternative embodiments, the disk gang angles corresponding to each residue piece length range may be different.

For instance, as described above, the computing system 112 may identify a plurality of residue pieces present within the portion of the field based on the received image data.
Additionally, at (306), the method 300 includes determining, with the computing system, the number of residue pieces of the identified plurality of residue pieces having a length within a first length range. For instance, as described above, the computing system 112 may determine the number of residue pieces of the identified plurality of residue pieces having a length within a first length range.
Moreover, at (308), the method 300 includes determining, with the computing system, the number of residue pieces of the identified plurality of residue pieces having a length within a second length range. For instance, as described above, the computing system 112 may determine the number of residue pieces of the identified plurality of residue pieces having a length within a different, second length range.
In addition, at (310), the method 300 includes determining, with the computing system, a characteristic length range for the portion of the field. For instance, as described above, the computing system 112 may determine a characteristic length range for the portion of the field. The characteristic length range, in turn, corresponds to one of the first length range or the second length range having the greatest number of residue pieces associated therewith.
Furthermore, at (312), the method 300 includes controlling, with the computing system, an operating parameter of a ground-engaging tool of the agricultural implement based on the determined characteristic length range. For instance, as described above, the computing system 112 may control one or more operating parameter(s) (e.g., the relative positioning of, the penetration depth(s) of, and/or the force(s) being applied to) of the ground-engaging tool(s) of the agricultural implement 12 based on the determined characteristic length range. In some embodiments, the computing system 112 may control the operation of the disk gang actuator(s) 110 to adjust angle(s) of the disk gang(s) 48 of the agricultural implement 12 based on the determined characteristic length range.
