Description

[Technical field]

[0001] The present invention relates to a program and a device for assisting in coupling an agricultural implement to a tractor. [Background technology]

[0002] Conventionally, when connecting an agricultural implement to a tractor, it is necessary to appropriately select and set the length of the top link and the position of each mounting hole depending on the combination of the hitch, which is the connecting means for the agricultural implement, and the three-point linkage mechanism, which is the connecting means for the tractor. These selections and settings require complicated tasks such as referring to a table in the instruction manual that lists the settings for many combinations, or selecting and setting the hitch (farm implement) and the tractor's three-point linkage mechanism in the specified positions so that they can be connected properly. In response to this, a system has been known that can check the matching (possibility of combination) between an agricultural machine and a three-point linkage mechanism of a tractor (see Patent Document 1).

[0003] [Patent Document 1] JP 2005-11 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, the task of connecting an agricultural implement to a tractor (matching task) is a complicated task, and such a task can lead to incorrect selection and setting. If the agricultural implement is incorrectly connected in this way, it may not be possible to put the agricultural implement in the desired position, or the agricultural implement may collide with the body of the tractor when lifted. Furthermore, the matching inquiry support device described in Patent Document 1 only provides information on whether an agricultural implement and a tractor can be connected, and the part replacement and improvement methods required to enable the connection, but does not provide specific selection and setting of the length of the top link, the position of each mounting hole, etc., when connecting the agricultural implement to the tractor. Therefore, even now, when connecting an agricultural implement to a tractor, the problem remains that the complicated task of appropriately selecting and setting the length of the top link and the position of each mounting hole, etc., depending on the combination of the hitch and the tractor's three-point linkage mechanism, has not been resolved.

The agricultural machine is not limited to a rotary tiller, but may be any agricultural machine that can be connected to a tractor. The connecting mechanism of the tractor is not limited to a three-point linkage, but may be a different connecting mechanism such as a two-point linkage. Furthermore, since three-point links, two-point links, hitches, etc. are all well-known mechanisms, their explanation will be omitted.

[0011] [Agricultural machinery matching support system] FIG. 1 is a block diagram of an agricultural machine matching support system according to an embodiment of the present invention. The agricultural machine matching support program of this embodiment is executed by a smartphone 1 which is an agricultural machine matching support device. The smartphone 1 is connected to a server 2 via the Internet. The smartphone 1 is equipped with an information input unit 11 for inputting various data, an information processing unit 12 having an arithmetic circuit such as a central processing unit (CPU), a memory unit 13 having various memories such as ROM and RAM for storing various programs including an agricultural machinery matching support program and various data, a display unit 14 for displaying various information such as various data and processing results by the information processing unit 12, and a communication unit 15 for communicating with external information processing units, memory units, etc., either directly or via a network such as the Internet. The server 2 is equipped with an information input unit 21 for inputting various data, an information processing unit 22 having an arithmetic circuit such as a central processing unit (CPU), a memory unit 23 (external memory unit) having various memories such as ROM and RAM for storing various programs including an agricultural machinery matching support program and various data, and a communication unit 24 for communicating with external information processing units, memory units, etc., either directly or via a network such as the Internet. The smartphone 1 downloads and installs the agricultural machine matching support program and various data from the storage unit 23 (external storage unit) of the server 2 to the smartphone 1 via the Internet.

[0012] [Agricultural machinery matching support program] As described above, the agricultural work machine matching support program of this embodiment is installed in the smartphone 1. When the agricultural work machine matching support program is read out from the storage unit 13 and executed by the information processing unit 12 in response to an operation of the smartphone 1 by an operator, the information processing unit 12 executes a series of processes for performing information output processing for outputting matching support information between the agricultural work machine and the tractor to the display unit 14.

[0013] In this embodiment, the agricultural machine matching support program is configured to perform information output processing to specify matching support information based on information input by the worker and output the specified matching support information to the display unit. The matching support information is information for guiding and supporting the worker so that the worker can perform an appropriate matching operation when performing a matching operation of connecting the agricultural machine to the tractor, and includes information on various setting values ​​that are preset for each combination of the tractor, hitch, agricultural machine, and joint, navigation information for navigating the matching operation (details will be described later), various explanatory image information, etc. In addition to the agricultural machine matching support program, various data including a combination table and image information to be described later that are used in this program are all downloaded from the storage unit 23 of the server 2 and stored in the storage unit 13 of the smartphone 1 in this embodiment.

[0014] 2 to 4 are diagrams showing flowcharts of the agricultural machine matching support program. FIG. 5 is a diagram explaining how to input tractor information in an embodiment of the present invention, FIG. 6 is a diagram explaining how to input hitch information in an embodiment of the present invention, FIG. 7 is a diagram explaining how to input agricultural machine information in an embodiment of the present invention, and FIG. 8 is a diagram explaining how to input joint information in an embodiment of the present invention, where (a) is a diagram showing the display screen 141 of the smartphone 1 and (b) is a diagram showing a pull-down display. When the worker operates the smartphone 1 to start up the agricultural work machine matching support program, the agricultural work machine matching support program is executed. In the agricultural machine matching support program of this embodiment, the various information for identifying the matching support information is stored in the following order: tractor information, hitch information, agricultural machine information, and joint information, but any order may be used. Also, it is not necessary to store all of the tractor information, hitch information, agricultural machine information, and joint information, and the program may not store some of the information, may omit storing some of the information based on information that has already been stored, or may not store some of the information due to an operation by the operator.

[0015] When the agricultural work machine matching support program is executed, first, in step S1, the information processing unit 12 of the smartphone 1 reads out image information for the worker to input information of a tractor to be matched with the agricultural work machine from the storage unit 13, and outputs a tractor information input image to the display unit 14. After the tractor information input image is output to the display unit 14, the process proceeds to step S2 in which the input of the tractor information is confirmed. In step S1, as shown in Fig. 5(a), a tractor information input image for the worker to input the tractor information is displayed on the display screen 141 of the display unit 14. In step S2, the information processing section 12 determines whether the tractor information has been input, and repeats this determination until the tractor information has been input. The three-point link of the tractor can be specified by the tractor name (tractor information) indicating the type of tractor used. In this embodiment, the three-point link corresponding to the tractor is specified by specifying the tractor information from the tractor name input by the worker. In this embodiment, the tractor name is input by displaying a list of multiple tractor names using a pull-down menu as shown in FIG. 5(b). The worker inputs the tractor name by selecting a tractor name to be matched with the agricultural machine from the displayed list of tractor names. Data (image information) related to multiple tractor names and images indicating their shapes and structures is stored in advance in the storage unit 13. The tractor name is, for example, a manufacturer name, a symbol indicating the model, a number, or a combination of these.

[0016] In this embodiment, the image of the three-point link of the tractor displayed in correspondence with the tractor name selected by the worker also changes. That is, an image showing the detailed shape and structure of the three-point link (target member) corresponding to the tractor name highlighted by the worker's operation among the tractor names displayed in the pull-down menu is displayed on the display screen 141 of the display unit 14. The worker looks at the displayed tractor name and the image of the three-point link corresponding to that tractor, and selects (determines) and inputs the tractor name matching the agricultural machine using the information input unit 11 (touch panel) provided in the smartphone 1. FIG. 5(a) shows a state in which the three-point link of a specific tractor is displayed as the three-point link. In this embodiment, an image showing the detailed shape and structure of the three-point link corresponding to each tractor name is displayed on the display screen 141 of the display unit 14. In other words, a different image of a three-point link is displayed for each tractor name, but one image of a three-point link is displayed in common to each tractor name. In other words, even if the tractor name displayed in reverse changes, the same image of a three-point link may continue to be displayed. Then, when the information processing unit 12 determines that the worker has operated the smartphone 1 to select (decide) the tractor name (Yes in step S2), it proceeds to step S3, where the information processing unit 12 stores the tractor name selected by the worker in the memory unit 13 as tractor information, and proceeds to step S4.

[0017] In this embodiment, the tractor names are displayed as a list using a pull-down menu, but instead of displaying the list using a pull-down menu, it is also possible to have the operator directly input the tractor name. Also, when the operator inputs part of a tractor name, tractor names including this may be displayed as selection candidates, allowing the operator to select the displayed tractor name. Also, when inputting a tractor name, it is also possible to display tractor names that have already been selected as candidates. Furthermore, it is also possible to display the tractor name selected in the previous setting as a default.

[0018] In step S4, the information processing unit 12 reads from the memory unit 13 image information for inputting information about the hitch on which the worker is attached to the tractor and to which the agricultural machine is attached, and outputs a hitch information input image to the display unit 14. After the hitch information input image is output to the display unit 14, the process proceeds to step S5 for confirming the input of the hitch information. By step S4, as shown in Fig. 6(a), a hitch information input image for the worker to input the hitch information is displayed on the display screen 141 of the display unit 14. In step S5, the information processing section 12 determines whether or not the hitch information has been input, and repeats this process until it determines that the hitch information has been input. When an autohitch (also called a quick hitch or one-touch hitch) is attached to the three-point link of a tractor to connect the tractor and an agricultural machine via the autohitch, the type of hitch can be specified by the autohitch name (hitch information). In this embodiment, the autohitch name can be input by selecting from a plurality of autohitch names using a pull-down menu as shown in FIG. 6(b). As with the tractor name data, a plurality of autohitch names and data (image information) relating to images showing their shapes and structures are stored in advance in the storage unit 13. The autohitch name may be any information that can specify the autohitch to be attached, and may be, for example, information showing the hitch standard, information combining the hitch standard and the manufacturer's name, other symbols, numbers, and combinations thereof.

[0019] In this embodiment, the image of the auto hitch displayed in correspondence with the auto hitch name selected by the worker also changes. That is, among the auto hitch names displayed in the pull-down menu, an image showing the detailed shape and structure of the auto hitch (target member) corresponding to the auto hitch name that is highlighted by the worker's operation is displayed. The method of selecting the auto hitch name is the same as the method of selecting the tractor name described above, and the worker looks at the displayed auto hitch name and the image corresponding to that auto hitch, and selects (determines) and inputs the auto hitch name to be used using the information input unit 11 (touch panel) provided in the smartphone 1. FIG. 6(a) shows a state in which a specific auto hitch is displayed as the hitch. Then, when the information processing unit 12 determines that the worker has operated the smartphone 1 to select (decide) the auto hitch name (Yes in step S5), it proceeds to step S6, where the information processing unit 12 stores the auto hitch name selected by the worker in the memory unit 13 as hitch information, and proceeds to step S7.

[0020] In this embodiment, the auto hitch names are displayed as a list using a pull-down menu, but instead of displaying the list using a pull-down menu, it is also possible to have the worker directly input the auto hitch name. Also, when the worker inputs part of an auto hitch name, auto hitch names including this may be displayed as selection candidates, and the displayed auto hitch name may be selected. Also, when inputting an auto hitch name, it is also possible to display auto hitch names that have already been selected as candidates. Furthermore, it is also possible to display the auto hitch name selected in the previous setting as a default.

[0021] In step S7, the information processing unit 12 reads out image information for the worker to input information about the agricultural work machine to be used from the memory unit 13, and outputs the agricultural work machine information input image to the display unit 14. After the agricultural work machine information input image is output to the display unit 14, the process proceeds to step S8 in which the input of hitch information is confirmed. By step S7, as shown in Fig. 7(a), an agricultural work machine information input image for the worker to input the agricultural work machine information is displayed on the display screen 141 of the display unit 14. In step S8, the information processing section 12 determines whether or not information about the agricultural machine has been input, and repeats this process until it determines that information has been input. When an attachment part (mast, guide pin, etc.) provided on an agricultural implement is directly connected to a three-point link of a tractor or connected via an auto hitch, the attachment part can be specified by the agricultural implement name (information on the agricultural implement), which is the type of agricultural implement to be used. In this embodiment, the agricultural implement name can be input by selecting from a plurality of agricultural implement names using a pull-down menu, as shown in FIG. 7(b). As with the tractor name data, data (image information) relating to a plurality of agricultural implement names and images showing their shapes and structures is stored in advance in the storage unit 13. The agricultural implement name is, for example, composed of a manufacturer name, a symbol indicating the model, a number, or a combination of these.

[0022] In this embodiment, the image of the agricultural machine displayed in correspondence with the agricultural machine name selected by the worker also changes. That is, an image showing the detailed shape and structure of the agricultural machine (target member) corresponding to the agricultural machine name highlighted by the worker's operation among the agricultural machine names displayed in the pull-down menu is displayed. The method of selecting the agricultural machine name is the same as the method of selecting the tractor name described above, and the worker looks at the displayed agricultural machine name and the image corresponding to that agricultural machine, and selects (determines) and inputs the agricultural machine name to be used using the information input unit 11 (touch panel) provided in the smartphone 1. FIG. 7(a) shows a state in which a specific rotary tiller is displayed as the agricultural machine. Then, when the information processing unit 12 determines that the worker has selected (decided) the agricultural machine name (Yes in step S8), it proceeds to step S9, where the information processing unit 12 stores the agricultural machine name selected by the worker in the memory unit 13 as agricultural machine information, and proceeds to step S10.

[0023] In addition, when the tractor's three-point link and the agricultural work machine are necessarily connected via an auto hitch, the process for storing information about the agricultural work machine may not be executed, the agricultural work machine matching support program may not have a process for storing information about the agricultural work machine, or when hitch information is input, the process for storing information about the agricultural work machine may not be executed. Furthermore, information on mounting parts (mast, guide pins, etc.) of the input agricultural work machine may be acquired as agricultural work machine information. Furthermore, if the agricultural work machine matching support program is applied only to a specific agricultural work machine, it does not need to have a program for storing information about the agricultural work machine.

[0024] In this embodiment, the names of agricultural machines are displayed as a list using a pull-down menu, but instead of displaying the list using a pull-down menu, it is also possible to have the worker directly input the name of the agricultural machine. Also, when the worker inputs part of the name of the agricultural machine, agricultural machine names including this may be displayed as selection candidates, and the displayed agricultural machine name may be selected. When inputting an agricultural machine name, it is also possible to display agricultural machine names that have already been selected as candidates. Furthermore, it is also possible to display the agricultural machine name selected in the previous setting as a default.

[0025] In this embodiment, matching support can also be provided for the joint that connects the PTO shaft of the tractor and the power input shaft of the agricultural machine. In step S10, the information processing unit 12 reads out image information for the worker to input information of the joint to be used from the storage unit 13, and outputs a joint information input image to the display unit 14. After the joint information input image is output to the display unit 14, the process proceeds to step S11 for confirming the input of joint information. By step S10, as shown in Fig. 8(a), a joint information input image for the worker to input joint information is displayed on the display screen 141 of the display unit 14. In step S11, the information processing section 12 determines whether or not joint information has been input, and repeats this process until it determines that the information has been input.

[0026] The type of joint to be used can be specified by the joint name (joint information). In this embodiment, the joint name can be input by selecting from a plurality of joint names (joint information) using a pull-down menu, as shown in FIG. 8(b). As with the tractor name data, data on a plurality of joint names and images (image information) showing their shapes and structures is stored in advance in the storage unit 13. The joint name can be, for example, a manufacturer name, a symbol indicating the model, a number, or a combination of these. In this embodiment, the image of the joint displayed in correspondence with the joint name selected by the worker also changes. That is, an image showing the detailed shape and structure of the joint (target member) corresponding to the joint name highlighted by the worker's operation among the joint names displayed in the pull-down menu is displayed. The method of selecting the joint name is the same as the above-mentioned method of selecting the tractor name, and the worker looks at the displayed joint name and the image corresponding to the joint, and selects (determines) and inputs the joint name to be used using the information input unit (touch panel) provided in the smartphone 1. FIG. 8(a) shows a state in which a specific joint is displayed as a joint. Then, when the information processing unit 12 determines that the worker has selected (decided) a joint name by operating the smartphone 1 (Yes in step S11), the information processing unit 12 proceeds to step S12, where it stores the joint name selected by the worker in the memory unit 13 as joint information, and proceeds to step S13.

[0027] In this embodiment, the joint names are displayed in a list using a pull-down menu, but instead of displaying the list using a pull-down menu, it is also possible to have the worker directly input the joint name. Also, when the worker inputs part of a joint name, joint names including this may be displayed as selection candidates, and the displayed agricultural machine name may be selected. When inputting a joint name, it is also possible to display joint names that have already been selected as candidates. Furthermore, it is also possible to display the joint name selected in the previous setting as a default.

[0028] In addition, the manner of the list display for the operator to select (decide) the type of tractor, hitch, agricultural implement, and joint can be modified in various ways. In this embodiment, the types of tractor, hitch, agricultural implement, and joint are displayed in a list so that they can be viewed by a pull-down menu, but the present invention is not limited to this. Since the types of agricultural implements and joints that can be matched are limited for each combination of the tractor type and the hitch type, it is possible to store combinations of the types of tractors, hitches, agricultural implements, and joints that can be matched, and after the worker selects (determines) the type of tractor and the type of hitch, the types of agricultural implements and joints displayed in a list by a pull-down menu are limited to only the agricultural implements and joints that can be matched, and the worker can select the desired agricultural implement or joint from the limited list. In this case, the number of types of agricultural implements and joints displayed in a list by a pull-down menu is reduced, making it easier for the worker to select from the list. In addition, the worker will not mistakenly select an agricultural implement or joint that cannot be matched with the tractor type and the hitch type that the worker has set in advance. If the agricultural implement or joint that the worker is trying to match is not displayed in the list, the worker can reconfirm whether the agricultural implement or joint can be matched with the tractor or the hitch.

[0029] Furthermore, after the worker first selects (decides) the type of tractor, the hitch names listed in the next pull-down menu are displayed limited to hitches that can be matched with the selected (decided) tractor, and after the worker selects (decides) the type of hitch, the agricultural implement names listed in the next pull-down menu are displayed limited to agricultural implements that can be matched with the selected (decided) tractor and hitch, and the joint names listed in the next pull-down menu are displayed limited to joints that can be matched with the selected (decided) tractor, hitch, and agricultural implement.In this way, as more type information is entered, the list is displayed limited to types that can be matched with the type already entered.

[0030] In addition, since the number of tractors, hitches, agricultural implements, and joints that a worker can use (own or borrow) is limited, the types of tractors, hitches, agricultural implements, and joints that the worker can use may be registered in advance, and only the registered types of tractors, hitches, agricultural implements, and joints may be displayed in a list using a pull-down menu. In this case, as described above, the list may be limited to agricultural implements and joints that can be matched with the combination of the selected (determined) tractor type and hitch type, or each time information on the type input increases, the list may be limited to types that can be matched with the types already input. Furthermore, possible matching combinations may be displayed based on the types of registered tractors, hitches, agricultural implements, and joints, and the worker may select (decide) the combination he or she wishes to match from the displayed combinations.

[0031] In step S13, the information processing unit 12 reads out image information for confirming to the worker that the input work has been completed from the storage unit 13, outputs it to the display unit 14, and proceeds to step S14. In step S13, a list of the information input by the worker is displayed, and a confirmation button (not shown) for confirming that the information input work has been completed is displayed on the display screen 141 of the display unit 14. In step S14, the information processing section 12 determines whether or not a confirmation operation (for example, operation of a confirmation button) has been performed by the operator, and repeats this process until it is determined that a confirmation operation has been performed. In addition, if there is an error in the information entered in step S13, when the worker selects (tap) the incorrect input information on the confirmation image in step S13, an input image corresponding to the input information is displayed, allowing the worker to input the correct information, or the worker may perform a specified operation to return to step S1 and re-enter the information from the beginning.

[0032] When the information processing unit 12 determines that the operator has performed a confirmation operation (Yes in step S14), the process proceeds to step S15, where the information processing unit 12 specifies various settings for matching the tractor and agricultural machine based on the tractor (three-point link) information, hitch information, agricultural machine information, and joint information stored in the memory unit 13, and then proceeds to step S16. The various settings include the length of the top link, the length of the lift rod, the positions of the mounting holes of the lift rod and lower link for mounting the lift rod and lower link, the position of the top link mounting hole of the tractor to which the top link is attached, the position of the top link mounting hole of the hitch to which the top link is attached, the length of the joint, etc. It is also possible to not display the confirmation button after the joint name is selected (determined).

[0033] FIG. 14 is a combination table of the agricultural machine matching support program according to the embodiment of the present invention. The various settings are specified based on a combination table stored in the storage unit 13 of the smartphone 1. The combination table defines set values ​​for various settings corresponding to combinations, and in the combination table of this embodiment, for each combination of a tractor, a hitch, an agricultural machine, and a joint, set values ​​(matching support information) for each combination indicating various settings for each combination, such as a top link adjustment length, a lift rod adjustment length, a lift rod / lower link hole position for attaching the lift rod and the lower link, a top link hole position for attaching the top link to the tractor, a hitch / lower link attachment for attaching the lower link to the hitch, a hitch / top link attachment for attaching the top link to the hitch, and a joint length, are defined. This combination table, like the agricultural machine matching support program, is downloaded in advance from the server's memory unit 23 to the smartphone 1, installed therein, and stored in the memory unit 13. For example, if the tractor name, hitch name, agricultural implement name, and joint name stored in the memory unit 13 are "T1XXX", "H4", "I1△△△", and "J2", respectively, the NO column is searched for NO "4" that matches these combinations, and the value of NO "4" is stored in the memory unit 13. It is not necessary to assign a NO to each combination and store the searched NO in the memory unit 13; the setting value for each searched combination may be stored in the memory unit 13.

[0034] In addition, if all of the tractor information, hitch information, agricultural implement information, and joint information are not necessary as information for identifying a combination, unnecessary information does not need to be used. For example, if joint matching assistance is not provided, only three pieces of information, tractor information, hitch information, and agricultural implement information, or only two pieces of information, tractor information and hitch information, may be used. Also, if the attachment part of the agricultural implement is connected to the tractor's three-point linkage without using an auto hitch, only two pieces of information, tractor information and agricultural implement information, may be used. The combination table may be composed of multiple combination tables, such as a combination table that specifies a combination using four pieces of information, a combination table that specifies a combination using three pieces of information, and a combination table that specifies a combination using two pieces of information, or a single combination table may incorporate a combination table that specifies a combination using four pieces of information, a combination table that specifies a combination using three pieces of information, and a combination table that specifies a combination using two pieces of information. Also, for example, one combination table may be constructed for each piece of information about a tractor, one combination table may be constructed for each piece of information about a hitch, one combination table may be constructed for each piece of information about an agricultural machine, etc. As described above, the combination table stored in the storage unit 13 of the smartphone 1 may be composed of either one combination table or multiple combination tables.

[0035] Fig. 9 is a diagram for explaining the display of information on the three-point link between the hitch and the tractor as matching support information according to an embodiment of the present invention, and Fig. 10 is a diagram for explaining the display of the completed state of the installation of the three-point link between the hitch and the tractor as matching support information according to an embodiment of the present invention. In Fig. 9, in correspondence with the locations where the settings in Fig. 9 are displayed, a display showing work procedures 1 to 6 among the work procedures displayed in the navigation display described below, and a display in which the setting values ​​corresponding to these work procedures are added are displayed. Note that only one of these two displays may be displayed.

[0036] In this embodiment, first, as shown in FIG. 9, the various settings identified are displayed in their entirety, and image information showing the shapes and structures of the top link, lower link, lift rod, etc., which are the members (target members) for which these various settings are presented, is included. In step S16, the information processing unit 12 reads out image information (including image information showing the shape and structure of the top link, lower link, lift rod, etc.) based on the combination setting values ​​corresponding to the identified NO from the memory unit 13, outputs it to the display unit 14, and proceeds to step S17. As a result, as shown in FIG. 9, the display screen 141 of the display unit 14 displays the detailed shape and structure of the tractor's three-point link corresponding to the input tractor information and the hitch corresponding to the input hitch information, including the top link, lift rod, lower link, hitch, and tractor-side mounting part (target parts) in a roughly combined arrangement, and also displays the length of the top link and the length of the lift rod, and displays in an easily-identifiable manner the positions of the mounting holes for the lift rod and lower link, the position of the top link mounting hole on the tractor to which the top link is attached, and the position of the top link mounting hole on the hitch to which the top link is attached. In addition, the configuration is not limited to reading out image information of all target components based on the setting values ​​for each combination corresponding to the identified No. from the memory unit 13, but image information of each target component based on the setting values ​​for each combination of the identified target components may be read out from the memory unit 13 and combined. In addition, in FIG. 9, the setting values ​​for each identified combination (matching support information) are displayed in addition to the display location of each setting value.

[0037] For example, FIG. 9 shows the display contents when the number "4" in the combination table shown in FIG. 14 is specified. FIG. 9 displays six types of matching support information: the length of the top link, the length of the lift rod, the positions of the mounting holes on the lift rod and lower link when attaching them to the lift rod and lower link, the position of the top link mounting hole on the tractor when attaching the top link, and the position of the top link mounting hole on the hitch when attaching the top link.

[0038] The length of the top link is indicated on the top link diagram to show the dimensions of the top link. The value is the top link adjustment length a2, which is the set value for each combination. This indication of the top link length corresponds to the operation procedure 1 "top link adjustment" of the navigation display (see Fig. 11(a)) described later. The length of the lift rod is indicated on the lift rod drawing to show the dimensions of the lift rod. The value is the lift rod adjustment length b2, which is the set value for each combination. This indication of the lift rod length corresponds to the work step 2 "Lift rod adjustment" (see Figure 11(b)) of the navigation display, which will be described later.

[0039] The positions of the mounting holes of the lift rod and the lower link when attaching the lift rod and the lower link are displayed so that the specified holes among the multiple mounting holes of the lift rod and the lower link can be distinguished from the other holes. In this embodiment, the specified mounting holes are displayed by encircling them. The color of the circle is preferably a color that is different from the display color of the member, etc. and is conspicuous. In addition, the mounting holes themselves may be colored, or an arrow pointing to the mounting holes may be added. These mounting holes correspond to the lift rod hole position c3 of the set value for each combination. The display of the mounting hole positions of the lift rod and the lower link corresponds to the operation procedure 3 "Lower link adjustment" (see FIG. 11(c)) of the navigation display described later.

[0040] The position of the tractor top link mounting hole when the top link is attached is displayed so that the specified hole among the multiple mounting holes of the tractor top link mounting holes can be distinguished from the other holes. In this embodiment, the specified tractor top link mounting hole and the tractor mounting hole of the top link are displayed in a circle. The color of this circle is preferably a conspicuous color different from the display color of the member, etc. In addition, the mounting hole itself may be colored, or an arrow pointing to the mounting hole may be added. This tractor top link mounting hole corresponds to d2 of the top link mounting hole of the set value for each combination. The display of these specified tractor top link mounting holes and top link mounting holes corresponds to the operation procedure 4 "top link installation" (see FIG. 11(d)) of the navigation display described later.

[0041] In this embodiment, the position of the lower link mounting hole of the hitch when attaching the lower link is one, and the lower link mounting hole of the hitch and the hitch mounting hole of the lower link are displayed as being surrounded by a circle. The color of this circle is preferably a color that is different from the display color of the components and is conspicuous. In addition, the mounting holes themselves may be colored, or arrows or the like may be added to indicate the mounting holes. These lower link mounting holes of the hitch and the hitch mounting holes of the lower link correspond to e2 of the hitch / lower link mounting setting value for each combination. The display of these lower link mounting holes of the hitch and the hitch mounting holes of the lower link corresponds to operation step 5 "Hitch installation 1 (circled number)" (see FIG. 11(e)) on the navigation display described later.

[0042] The position of the top link mounting hole of the hitch when the top link is attached is displayed so that the specified hole among the multiple mounting holes of the top link mounting hole of the hitch can be distinguished from the other holes. In this embodiment, the specified top link mounting hole of the hitch and the tractor mounting hole of the top link are displayed in a circle. The color of this circle is preferably a color that is different from the display color of the member, etc. and is conspicuous. In addition, the mounting hole itself may be colored, or an arrow pointing to the mounting hole may be added. The top link mounting hole of this hitch corresponds to f2 of the hitch-top link mounting setting value for each combination. The display of these specified top link mounting holes of the hitch and the hitch mounting holes of the top link corresponds to the operation procedure 6 "Hitch mounting 2 (circled number)" (see FIG. 11(f)) of the navigation display described later.

[0043] In addition, if you perform an operation to change the display while the various setting information shown in Figure 9 is being displayed, an image of the tractor's three-point linkage and hitch with their installation completed will be displayed, as shown in Figure 10. These two views can be switched at any time by changing the display. In step S17, the information processing section 12 determines whether or not the operator has performed a display change operation. In step S17, if the information processing unit 12 determines that the worker has performed a display change operation (Yes in step S17), it proceeds to step S18, and if it determines that the worker has not performed a display change operation (No in step S17), it proceeds to step S19. In step S18, the information processing section 12 switches between the display shown in FIG. 9 and the display shown in FIG. 10 as described above, and returns to step S17.

[0044] That is, when an image based on the set values ​​for each combination corresponding to the specified No. shown in Fig. 6 (an image showing the shape and structure of the top link, lower link, lift rod, etc.) is displayed on the display screen 141 of the display unit 14, the information processing unit 12 reads out image information of the completed state of attachment of the hitch and the three-point link of the tractor based on the set values ​​for each combination corresponding to the specified No. shown in Fig. 10 from the storage unit 13, and outputs it to the display unit 14. As a result, an image of the completed state of attachment of the three-point link of the tractor and the hitch based on the set values ​​for each combination corresponding to the specified No. is displayed on the display screen 141 of the display unit 14, as shown in Fig. 10. Furthermore, when an image of the completed state of attachment of the hitch and the three-point link of the tractor based on the set values ​​for each combination corresponding to the specified NO shown in Fig. 10 is displayed on the display screen 141 of the display unit 14, the information processing unit 12 reads out image information (images showing the shapes and structures of the top link, lower link, lift rod, etc.) based on the set values ​​for each combination corresponding to the specified NO shown in Fig. 9 from the storage unit 13, and outputs it to the display unit 14. As a result, an image (images showing the shapes and structures of the top link, lower link, lift rod, etc.) based on the set values ​​for each combination corresponding to the specified NO is displayed on the display screen 141 of the display unit 14, as shown in Fig. 9.

[0045] In addition, on the display screen 141 of the display unit 14, a button (not shown) for changing the display is displayed together with the information display as shown in FIG. 9. When the worker taps the button for changing the display in the display state as shown in FIG. 9, the image displayed on the display screen 141 is switched to an image of a state in which the attachment of the three-point link and the hitch of the tractor is completed as shown in FIG. 10. Similarly, when the information display as shown in FIG. 10 is performed, a button for changing the display (not shown) is displayed on the display screen 141. When the worker taps the button for changing the display in the display state as shown in FIG. 10, the image displayed on the display screen 141 is switched to the information display as shown in FIG. 9. The operation for changing the display is not limited to tapping the button display on the display screen, but may be pressing an operation button provided on the smartphone 1.

[0046] In addition, in Figures 9 and 10, the three-point link and hitch of the tractor are all displayed together, but this is not limited thereto. The information may be divided into two displays: information related to the top link, such as the length of the top link, the position of the top link mounting hole of the tractor to which the top link is attached, and the position of the top link mounting hole of the hitch to which the top link is attached; and information related to the lower link, such as the length of the lift rod and the positions of the mounting holes of the lift rod and the lower link for attaching the lift rod and the lower link; or the information may be divided into many displays. In addition, it is not necessary to display both Figures 9 and 10, and it is possible to display either one of them. In the case where only Figure 10 is made displayable, it is preferable to display the length of the top link and the length of the lift rod in Figure 10.

[0047] In this way, the settings required to perform the matching work according to the combination of the tractor, hitch, and agricultural machine are displayed on the display screen 141 of the display unit 14. Therefore, the worker can perform the matching work correctly by performing the matching work while looking at this display screen. In this embodiment, not only are various settings displayed in their entirety, but numbers representing the recommended procedure for the matching process are also displayed on the display screen, as shown in FIG. 9, so that the user can proceed with the matching process appropriately by working through the steps in the numerical order.

[0048] In step S19, the information processing unit 12 determines whether the worker has performed a display change operation for checking the joints. In step S19, if the information processing unit 12 determines that the worker has performed a display change operation to check the joints (Yes in step S19), it proceeds to step S20, and if it determines that the worker has not performed a display change operation to check the joints (No in step S19), it proceeds to step S25. In addition, on the display screen 141 of the display unit 14, together with the information display shown in FIG. 9 or FIG. 10, a button (not shown) for moving on to joint confirmation is displayed, and when this button is tapped (Yes in step S19), the process moves to step S20.

[0049] In step S20, the information processing unit 12 reads out from the storage unit 13 image information (a message confirming that the inner and outer cylinders of the drive shaft of the joint can be extended and retracted within a predetermined range of length, and an image of the joint) for prompting the worker to confirm that the preparation for attaching the joint based on the combination setting value corresponding to the identified NO has been properly performed, outputs it to the display unit 14, and proceeds to step S21. As a result, a message confirming that the inner and outer cylinders of the drive shaft of the joint can be extended and retracted within a predetermined range of length, and an image of the joint (an image prompting the worker to confirm the dimensions of the joint) are displayed on the display screen 141 of the display unit 14, as shown in Fig. 12(g). In addition, if an operation is performed to change the display while the image prompting the user to check the dimensions of the joint shown in Figure 12(g) is displayed, an image prompting the user to check the condition of the hitch, as shown in Figure 12(h), is displayed. These two views can be switched at any time by changing the display.

[0050] In step S21, the information processing section 12 determines whether or not the operator has performed a display change operation. In step S21, if the information processing unit 12 determines that the worker has performed a display change operation (Yes in step S21), it proceeds to step S22, and if it determines that the worker has not performed a display change operation (No in step S21), it proceeds to step S23. In step S22, the information processing section 12 switches the display shown in FIG. 12(g) and the display shown in FIG. 12(h) as described above, and returns to step S21. That is, when an image prompting the user to check the dimensions of the joint shown in Fig. 12(g) is displayed on the display screen 141 of the display unit 14, the information processing unit 12 reads out image information prompting the user to check the state of the hitch shown in Fig. 12(h) from the storage unit 13 and outputs it to the display unit 14. As a result, an image prompting the user to check the state of the hitch is displayed on the display screen 141 of the display unit 14, as shown in Fig. 12(h). Furthermore, when an image prompting the user to check the hitch state shown in Fig. 12(h) is displayed on the display screen 141 of the display unit 14, the information processing unit 12 reads out image information prompting the user to check the dimensions of the joint shown in Fig. 12(g) from the storage unit 13 and outputs it to the display unit 14. As a result, an image prompting the user to check the dimensions of the joint is displayed on the display screen 141 of the display unit 14, as shown in Fig. 12(g). The displayed image can be changed by tapping the arrows (←, →) shown in Figures 12(g) and (h).

[0051] In step S23, the information processing section 12 determines whether or not the operator has performed a return operation. In step S23, if the information processing unit 12 determines that the worker has performed a back operation (Yes in step S23), it proceeds to step S16, and if it determines that the worker has not performed a back operation (No in step S23), it proceeds to step S24. In addition, on the display screen 141 of the display unit 14, a back button (not shown) is displayed together with the displays shown in FIG. 12(g) and FIG. 12(h). When the worker taps the back button (Yes in step S23), the process proceeds to step S16. In step S24, the information processing section 12 determines whether or not the operator has performed an operation to end the agricultural machine matching support program. In step S24, if the information processing unit 12 determines that the worker has performed the termination operation (Yes in step S24), it terminates the processing, and if it determines that the worker has not performed the termination operation (No in step S24), it proceeds to step S20. In addition, on the display screen 141 of the display unit 14, an end button (not shown) is displayed together with the displays shown in Figures 12(g) and 12(h), and when the worker taps the end button (Yes in step S24), the processing is terminated.

[0052] 11 and 12 are diagrams for explaining the display of navigation for a work procedure for connecting an agricultural machine and a tractor with a three-point linkage as matching support information according to an embodiment of the present invention. In step S25, the information processing section 12 determines whether the operator has performed a display change operation to display the navigation screen. In step S25, if the information processing unit 12 determines that the operator has performed a display change operation to display navigation (Yes in step S25), it proceeds to step S26, and if it determines that the operator has not performed a display change operation to display navigation (No in step S25), it proceeds to step S31. 9 or 10, an operation button (not shown) for displaying a navigation display is displayed on the display screen 141 of the display unit 14, and tapping this operation button (Yes in step S25) causes the process to proceed to step S26. Note that the navigation display may be performed without displaying the information on various settings shown in FIG. 9 and the installation completion diagram shown in FIG. 10. In the navigation display, the navigation for each task is displayed in a set order, as shown below. When you have completed a task by following the displayed navigation, you can move on to the navigation for the next task (tap the arrow (→) on the right side of each display in Figures 11 and 12), and the navigation for the next task will be displayed. Also, if you move on to the navigation for the previous task (tap the arrow (←) on the left side of each display), the navigation for the previous task will be displayed.

[0053] In step S26, the information processing unit 12 reads out, from the memory unit 13, navigation image information of messages and images indicating the work procedures shown in FIG. 11(a) based on the setting values ​​for each combination stored in the memory unit 13, outputs it to the display unit 14, and proceeds to step S27. In step S27, the information processing section 12 determines whether or not the operator has performed a display change operation. In step S27, if the information processing unit 12 determines that the worker has performed a display change operation (Yes in step S27), it proceeds to step S28, and if it determines that the worker has not performed a display change operation (No in step S27), it proceeds to step S29. The displayed image can be changed by tapping the arrows (←, →) shown in Figures 11 and 12. In step S28, the information processing unit 12 reads out image information corresponding to the operator's display change operation from the storage unit 13, outputs it to the display unit 14, and then returns to step S27. As described above, in this embodiment, first an image relating to work procedure 1, which will be described later, is displayed on the display screen 141 of the display unit 14, and then, based on the operation of the worker, images relating to the previous and next work procedures are displayed on the display screen 141 of the display unit 14. Note that the images displayed in the following work steps 1 to 6, 9, and 10 are displayed based on the setting values ​​for each combination, and work steps 7 and 8 are displayed based on the information requesting confirmation mentioned above (matching support information).

[0054] 1. Top link adjustment When the worker performs an operation to display navigation while the information shown in Fig. 9 or 10 is being displayed, the information processing unit 12 reads out from the storage unit 13 a message for adjusting the length of the top link to be used and image information of the image of the top link, as shown in Fig. 11(a), and outputs it to the display unit 14. As a result, a message for adjusting the length of the top link to be used and an image of the top link are displayed on the display screen 141 of the display unit 14, as shown in Fig. 11(a). Note that the setting value is displayed in the XX mm portion, as shown in Fig. 9. The worker adjusts the length of the top link to the length specified in the message displayed on the display screen 141. The top link has a cylindrical member in the middle, and the rod members on both sides are capable of expanding and contracting in the axial direction by means of turnbuckles, and the length of the top link can be adjusted to the specified length by rotating the cylindrical member and the rod member relatively. After completing the adjustment of the top link, the worker moves to the next step (tap the arrow (→) on the right side displayed on the display screen 141). When the image shown in FIG. 11(a) is displayed on the display screen 141 of the display unit 14, if the left arrow (←) displayed on the display screen 141 is tapped, the back operation described below is regarded as being performed, and the image shown in FIG. 9 or FIG. 10 may be displayed, or the image shown in FIG. 12(j) described below may be displayed.
