An image sensor assembly is positioned downstream of the crop processor along a flow path of the crop material. The image sensor assembly is operable to capture a post-processing image of the crop material. A computing device is operable to execute a crop processing analysis algorithm to receive the post-processing image of the crop material from the image sensor assembly, and to analyze the post-processing image to determine an actual degree of processing to the characteristic of the crop material achieved by the crop processor. The computing device may then communicate a notification signal to an output indicating the actual degree of processing to the characteristic of the crop material.

[0031] Referring to the Figures, wherein like numerals indicate like parts throughout the several views, a harvester implement is generally shown at 20. The harvester implement 20 shown in the Figures and described herein is configured as a forage harvester. However, it should be appreciated that the harvester implement 20 may be configured differently than the example forage harvester shown in the Figures and described herein.

[0034] Referring to
[0035] Referring to
[0036] In the example implementation shown in the Figures, the cutter head 40A is positioned downstream of the feeder 34, relative to the flow path 28 of the crop material. The cutter head 40A is rotatably attached to the frame 22 and is rotatable about an axis of rotation. The axis of rotation of the cutter head 40A is generally perpendicular to the direction of travel 32 of the harvester implement 20 while gathering crop material, and generally perpendicular to the direction of crop processing. The example embodiment of the cutter head 40A shown in the Figures and described herein includes a cylindrical drum 42 having a plurality of knives 44 disposed circumferentially about the outer periphery of the drum 42.
[0037] Referring to
[0038] Referring to
[0039] The harvester implement 20 further includes a discharge spout 54. The discharge spout 54 is positioned downstream of the kernel processor 40B relative to the flow path 28 of the crop material. The discharge spout 54 includes an inlet 56 positioned to receive the crop material from the crop processor 40A, 40B, e.g., the cutter head 40A and the kernel processor 40B, and partially defines the flow path 28 of the crop material. The discharge spout 54 may include an exit 58 that is positioned to expel the crop material into a storage container 60. The discharge spout 54 may include, but is not limited to, an elongated tubular structure that is shaped to guide and direct the crop material into the storage container 60. In one implementation, the storage container 60 may include a bin supported by the frame 22 and integral with the harvester implement 20. In another implementation, such as shown in
[0040] Referring to
[0041] Referring to
[0042] In other alternative implementations, the image sensor assembly 66 may be positioned to capture the post-processing image 68 of the crop material as the crop material is expelled from the discharge spout 54 and/or deposited in the storage container 60. As such, the image sensor assembly 66 may be located on an exterior of the harvester implement 20 and positioned to capture the flow of the crop material as the crop material is dispensed from the exit 58 of the discharge spout 54 and into the storage container 60. In yet another implementation, the image sensor assembly 66 may be located on the storage container 60, e.g., a truck or trailer positioned adjacent to the forage harvester. In this implementation, the image sensor assembly 66 may be positioned to capture the flow of the crop material as the crop material is dispensed from the exit 58 of the discharge spout 54 and into the storage container 60. It should be appreciated that the image sensor assembly 66 may be positioned at some other location not specifically described herein, either on or off the harvester implement 20, that enables the image sensor assembly 66 to capture the post-processing image 68 of the crop material.
[0043] Referring to
[0044] Because the crop material may include abrasive materials, the window covering 76 may include and/or be manufactured from an abrasive resistant material. For example, the window covering 76 may include or be manufactured from a sapphire glass or ceramic glass. However, it should be appreciated that the window covering 76 may include and be manufactured from some other transparent, abrasion resistant material, not mentioned or described herein.
[0045] Referring to
[0046] Each of the light sources 78 positioned within the interior region 72 of the housing 70 is positioned to provide direct lighting through the opening 74 of the housing 70 and through the window covering 76 extending over the opening 74, and onto the crop material in the flow path 28. As used herein, the term “direct lighting” is defined as illumination directly from the light source 78 that has not been reflected off of another surface.
[0047] In the example implementation described herein, each of the light sources 78 may include a pulsed light source 78. As used herein, the term “pulsed” defines a light source 78 that is controlled on/off for each post-processing image 68 that is captured. In other words, the pulsed light source 78 is not continuously on, but is rather turned on in order to capture the post-processing image 68, then turned off. In the example implementation described herein, each of the light sources 78 may include, but are not limited to, a Light Emitting Diode (LED) that is operable to emit light in the visible light spectrum. The visible light spectrum may include light having a wavelength between the range of approximately 380 nanometers and 700 nanometers. While the example implementation of the light sources 78 includes LED lights, it should be appreciated that the light sources 78 may include some other construction not described herein that is capable of emitting light in the visible light spectrum.
[0048] Referring to
[0049] In the example implementation described herein, the camera module 80 is operable to capture the post-processing image 68 in the visible light spectrum. As noted above, the visible light spectrum includes light having a wavelength between the range of approximately 380 nanometers and 700 nanometers. While the example implementation of the light sources 78 and the camera module 80 include emitting light and capturing images in the visible light spectrum, it should be appreciated that other light spectrums may alternatively be used.
[0050] Referring to
[0051] Referring to
[0052] As used herein, “computing device” or “controller” are intended to be used consistent with how the term is used by a person of skill in the art, and refers to a computing component with processing, memory 90, and communication capabilities, which is utilized to execute instructions (i.e., stored on the memory 90 or received via the communication capabilities) to control or communicate with one or more other components. In certain embodiments, a controller may also be referred to as a control unit, vehicle control unit (VCU), engine control unit (ECU), transmission control unit (TCU), or electrical controller. In certain embodiments, a controller may be configured to receive input signals in various formats (e.g., hydraulic signals, voltage signals, current signals, CAN messages, optical signals, radio signals), and to output 62 command or communication signals in various formats (e.g., hydraulic signals, voltage signals, current signals, CAN messages, optical signals, radio signals).
[0053] The computing device 86 may be in communication with other components on the harvester implement 20, such as hydraulic components (e.g., valve block), electrical components (e.g., solenoid, accumulator sensor), actuators, sensors 92, and operator inputs within an operator station of the work vehicle. The computing device 86 may be electrically connected to these other components by a wiring harness such that messages, commands, and electrical power may be transmitted between the computing device 86 and the other components. Although the computing device 86 is referenced in the singular, in alternative implementations the configuration and functionality described herein can be split across multiple computing device 86s using techniques known to a person of ordinary skill in the art.
[0054] The computing device 86 may be embodied as one or multiple digital computers or host machines each having one or more processors 88, read only memory (ROM), random access memory (RAM), electrically-programmable read only memory (EPROM), optical drives, magnetic drives, etc., a high-speed clock, analog-to-digital (ND) circuitry, digital-to-analog (D/A) circuitry, and any required input/output (I/O) circuitry, I/O devices, and communication interfaces, as well as signal conditioning and buffer electronics.
[0055] The computer-readable memory 90 may include any non-transitory/tangible medium which participates in providing data or computer-readable instructions. The memory 90 may be non-volatile or volatile. Non-volatile media may include, for example, optical or magnetic disks and other persistent memory. Example volatile media may include dynamic random access memory (DRAM), which may constitute a main memory. Other examples of embodiments for memory include a floppy, flexible disk, or hard disk, magnetic tape or other magnetic medium, a CD-ROM, DVD, and/or any other optical medium, as well as other possible memory devices such as flash memory.
[0056] Referring to
[0057] As described above, the computing device 86 includes the processor 88 and the memory 90. The memory 90 includes a crop processing analysis algorithm 104 stored thereon. The processor 88 is operable to execute the crop processing analysis algorithm 104 to implement a method of monitoring the operation of the crop processor 40A, 40B, and/or controlling the harvester implement 20.
[0058] Referring to
[0059] Once the desired level of crop conditioning has been input into the computing device 86, operation of the harvester implement 20 may begin. The step of operating the harvester implement 20 is generally indicated by box 202 in
[0060] In the example implementation of the harvester implement 20 described herein, as the crop material moves through the discharge spout 54, the processor 88 is operable to execute the crop processing analysis algorithm 104 to activate the light source 78 of the image sensor assembly 66 to illuminate the crop material adjacent to the window covering 76 and then actuate the camera module 80 to capture the post-processing image 68 of the crop material. The step of capturing the post-processing image 68 is generally indicated by box 204 in
[0061] The processor 88 is operable to execute the crop processing analysis algorithm 104 to receive the post-processing image 68 of the crop material from the image sensor assembly 66. The post-processing image 68 may then be stored in the memory 90 of the computing device 86. The post-processing image 68 may be communicated between the image sensor assembly 66 and the computing device 86 through a wired connection, a wireless connection, a CAN bus, etc.
[0062] The computing device 86 may then analyze the post-processing image 68 to determine an actual degree of processing to the characteristic of the crop material achieved by the crop processor 40A, 40B. The step of determining the actual degree of processing to the characteristic of the crop material is generally indicated by box 206 in
[0063] In another example, the computing device 86 may use object recognition software to identify a kernel portion of the crop material, and then use artificial intelligence software to compare the identified kernel portion to pre-learned images stored in the memory 90 and related to specific degrees of kernel wall fracture. By doing so, the computing device 86 may determine how much of the wall of the kernel portion is fractured or cracked, i.e., an actual degree of kernel fracture. The computing device 86 may then relate the actual degree of kernel fracture to a kernel processing score. It should be appreciated that the kernel processing score may represent an industry accepted standard representing the amount, level, or percentage of the wall of the kernel that is cracked or fractured. For example, the United States Department of Agriculture (USDA) uses a Kernel Processing Score (KPS) providing a Goal level that is equal to or greater than seventy percent (70%) kernel wall fracture, and Adequate level that is between fifty percent (50%) and seventy percent (70%) kernel wall fracture, and a Poor level that is equal to or less than fifty percent (50%) kernel wall fracture. It should be appreciated that the USDA KPS score described above is merely exemplary, and that the desired level of crop conditioning and the actual degree of kernel fracture may be expressed in some other manner, using some other scale 110 or scoring system.
[0064] Once the actual degree of processing of the crop material has been determined, the processor 88 is operable to execute the crop processing analysis algorithm 104 to compare the actual degree of processing to the pre-defined allowable characteristic range to determine if the actual degree of processing is equal to or within the pre-defined allowable characteristic range or if the actual degree of processing is outside the allowable characteristic range. The step of determining if the actual degree of processing is within an allowable range is generally indicated by box 208 in
[0065] For example, the desired level of processing may include a desired cut length between the range of fifteen millimeters (15 mm) and twenty five millimeters (25 mm). If the actual cut length of the identified stem portion is determined to approximately seventy five millimeters (75 mm), then the computing device 86 may determine that the actual degree of processing, e.g., the actual cut length, is greater than the desired level of processing, i.e., the desired cut length, and thereby determine that maintenance and/or re-adjustment of one of the components of the harvester implement 20 may be required.
[0066] The computing device 86 may then communicate a notification signal to the output 62. The step of communicating the notification signal to the output 62 is generally indicated by box 218 in
[0067] The notification signal may include other data in addition to or as an alternative to the post-processing image 68. For example, the notification signal may indicate that the actual degree of processing is equal to or within the pre-defined allowable characteristic range or that the actual degree of processing is outside the allowable characteristic range. The notification signal may further include the actual cut length of the crop material in a first display section 112 of the output 62, and/or the actual degree of kernel processing or the kernel processing score in a second display section 114 of the output 62. It should be appreciated that other data may be included in the notification signal and presented on the visual display 106 as well, such as but not limited to, a geographic location of where the post-processing image 68 was taken, a time and date of the post-processing image 68, weather conditions at the time the post-processing image 68 was taken, etc.
[0068] As described above, if the computing device 86 determines that the actual degree of processing is not equal to or within the pre-defined allowable characteristic range, i.e., that the actual degree of processing is outside the pre-defined allowable characteristic range, generally indicated at 214, then maintenance to the crop processor 40A, 40B and/or an adjustment to the crop processor 40A, 40B may be required in order to achieve the desired level of processing. For this reason, the processor 88 may be operable to execute the crop processing analysis algorithm 104 to identify a potential maintenance requirement associated with the crop processor 40A, 40B based on the actual degree of processing to the crop material achieved by the crop processor 40A, 40B. The step of identifying a maintenance requirement is generally indicated by box 220 in
[0069] The computing device 86 may be configured to detect or otherwise determine, based on the determination that the actual degree of processing is not equal to or within the pre-defined allowable characteristic range and other sensor data related to the crop processor 40A, 40B, that the knives 44 of the cutter head 40A require sharpening and/or replacement, that the first processing roll 48 and/or the second processing roll 50 are worn and are in need of replacement, that one or more bearings on the rotating cylindrical drum 42 of the cutter head 40A, the first processing roll 48 of the kernel processor 40B, or the second processing roll 50 of the kernel processor 40B are worn and need replacing, etc. It should be appreciated that other components and features of the crop processor 40A, 40B, not specifically identified and/or described herein, may be identified by the computing device 86 for maintenance based on the data obtained at least partially from the post-processing image 68.
[0070] Furthermore, if the computing device 86 determines that the actual degree of processing is not equal to or within the pre-defined allowable characteristic range, i.e., that the actual degree of processing is outside the pre-defined allowable characteristic range, then the processor 88 may be operable to execute the crop processing analysis algorithm 104 to automatically adjust the crop processor 40A, 40B to change the actual degree of processing to the crop material achieved by the crop processor 40A, 40B. The step of adjusting the crop processor 40A, 40B is generally indicated by box 222 in
[0071] As noted above, the computing device 86 may include the GPS system 102 that is capable of receiving location data and determining a geographic location of the harvester implement 20. As such, the processor 88 may be operable to execute the crop processing analysis algorithm 104 to determine a geographic location of the crop material captured in the post-processing image 68, using the GPS system 102. The step of determining the geographic location is generally indicated by box 224 in
[0072] The processor 88 may further be operable to execute the crop processing analysis algorithm 104 to communicate the post-processing image 68, the actual degree of processing to the crop material, and the geographic location associated with the post-processing image 68, as well as other data if desired, to a remote data storage and/or access location 116. The step of communicating data to the access location 116 is generally indicated by box 226 in
[0073] Remote access to the real time data obtained from the post-processing image 68 may enable real time adjustments and/or decisions from users located remote from the harvester implement 20. For example, the processor 88 may be operable to execute the crop processing analysis algorithm 104 to receive a setting control input signal 122 from a remote transmitter 120. The step of receiving the setting control input signal 122 is generally indicated by box 228 in
[0074] As noted above, the harvester implement 20 may include the NIR sensor 82 that is capable of sensing the NIR image of the crop material. The processor 88 may be operable to execute the crop processing analysis algorithm 104 to analyze the NIR image to determine a moisture content and/or a starch content of the crop material. The moisture content and/or starch content of the crop material may be included in the notification signal communicated to the output 62, or may be included in the data communicated to the remote location 116.
[0075] It may be desirable to improve or increase digestible starch in the diet of some animals. For example, milk production in cows is dependent upon available or digestible starch. Starch is a major energy source for lactating dairy cows when digested in the rumen and/or absorbed in the intestine as glucose. Increasing ruminal starch digestion improves microbial protein synthesis, which is the main amino acid source for absorption in the small intestine. Improving or increasing the available or digestible starch in the cow's diet may increase milk production. If corn is too mature, however, the starch may be difficult for a cow to digest. Starch content in corn, for example, may range between 18% and 48%. However, the starch content in corn that is available or digestible by a cow may range between 5.8% and 7.8%.
[0076] As used herein, “e.g.” is utilized to non-exhaustively list examples, and carries the same meaning as alternative illustrative phrases such as “including,” “including, but not limited to,” and “including without limitation.” As used herein, unless otherwise limited or modified, lists with elements that are separated by conjunctive terms (e.g., “and”) and that are also preceded by the phrase “one or more of,” “at least one of,” “at least,” or a like phrase, indicate configurations or arrangements that potentially include individual elements of the list, or any combination thereof. For example, “at least one of A, B, and C” and “one or more of A, B, and C” each indicate the possibility of only A, only B, only C, or any combination of two or more of A, B, and C (A and B; A and C; B and C; or A, B, and C). As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Further, “comprises,” “includes,” and like phrases are intended to specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.
