[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0018] 1 is a configuration diagram of a rice transplanter as an example of an agricultural machine according to an embodiment of the present invention. In the following, forward / backward, left / right, and up / down are defined based on the traveling direction of the rice transplanter.

[0019] In FIG. 1, a traveling vehicle body 1 is provided with a control device 2 and a display 3 for displaying data.

[0020] The control device 2 can acquire position data of its own traveling vehicle body 1 through a receiver 4a capable of receiving radio waves from a satellite positioning device 4 such as GNSS. The control device 2 can also exchange data with an external server 5 through a receiving port 5a. The control device 2 is also connected to a connection port 6a to which an information storage device 6 such as a USB or tablet can be connected, which stores at least an identifier, encryption information, password, and other credential information. The tablet can be connected via wireless communication. The control device 2 is also connected to a work implement port 7a to which a variable-speed spraying work implement 7 is connected. When the variable-speed spraying work implement 7 is connected to the work implement port 7a, the control device 2 can communicate with the variable-speed spraying work implement 7. The control device 2 can also display data on a display 3.

[0021] As shown in Figure 2, the server 5 stores at least field position information 8 for each of a plurality of fields A, B, C, etc., and field map data 9 for each of the fields A, B, C, etc., such as fertilization map data and pest control map data. The field position information 8 includes position information, shape information, center of gravity information, map range information, etc., for each vertex.

[0022] The display 3 is capable of displaying various data and images under the control of the control device 2, including a standby screen for reading farm field map data.

[0023] Next, an example of the operation of this embodiment will be described. As shown in Figure 3, first, the control device 2 detects whether the information storage device 6 is connected to the connection port 6a, and if it is connected, checks the qualification information in the information storage device 6.

[0024] The control device 2 will not start the operation of acquiring the field map data if the information storage device 6 is not connected, or if it is connected but is not qualified.

[0025] Next, when a qualified information storage device 6 is connected, the control device 2 checks whether a standby screen for reading the field map data is displayed on the display 3. If the standby screen is not displayed, the control device 2 does not start the operation of acquiring the field map data.

[0026] By doing this, when the information storage device 6 is connected to the connection port 6a for another purpose, for example to save some image data in the information storage device 6, the operation of acquiring the field map data is not started, thereby preventing reading from occurring in an unintended situation. For this reason, an operator who intends to read the field map data needs to have the standby screen for reading the field map data displayed on the display device 3 in advance.

[0027] Next, the control device 2 obtains the position of its own traveling vehicle body 1 using data from the satellite positioning device 4. Then, it compares its own position with information on the field position etc. in the data stored in the server 5, and selects one field.

[0028] For example, the control device 2 compares the position data of its own traveling vehicle body 1 with the center of gravity position data in the field position information of each field A, B, C, etc. stored in the server 5, and selects the field having the center of gravity position data closest to the position data of its own traveling vehicle body 1. This is because an operator usually moves the traveling vehicle body 1 close to the field where he or she is about to work.

[0029] Alternatively, the control device 2 compares the position data of its own traveling vehicle 1 with the map range data in the field position information of each field A, B, C, etc. stored in the server 5, and selects the field whose range is included in the position data of its own traveling vehicle 1. The worker can reliably select the desired field by moving the traveling vehicle 1 inside the range of the field where he or she is about to work.

[0030] Next, the control device 2 checks whether an adjustable spraying implement 7 is connected to the implement port 7a and also checks its type. That is, for example, it checks whether an adjustable spraying implement 7 that complies with the AG-PORT standard (a common protocol for communication control of agricultural machinery) has been connected. If an adjustable spraying implement 7 is not connected, the operation of reading the field map data does not start.

[0031] To check whether the variable speed spraying implement 7 is connected to the implement port 7a, the control device 2 checks, for example, whether the ID in the communication information from the variable speed spraying implement 7 is an ID used for a specific variable speed spraying implement. For example, it checks whether it is an ID conforming to the AG-PORT standard. In other words, a specific CAN-ID is used. In this way, it is possible to exclude cases where an implement other than the variable speed spraying implement 7 is connected. In such cases, the operation of reading the field map data will not be started.

[0032] Furthermore, the control device 2 confirms whether the adjustable spraying machine 7 is connected to the machine port 7a by checking that the content of the communication information from the adjustable spraying machine 7 is content related to a specific adjustable spraying machine 7. The content of such communication information can be checked as spraying performance, machine type, machine determination information, etc. This makes it possible to determine whether the adjustable spraying machine 7 is a fertilizer application machine or a pest control machine.

[0033] As described above, when the control device 2 has already selected a target field, for example, when field A has been selected, it can further select target field map data from the type of implement obtained from the adjustable spraying implement 7 in this way (see Figure 2). That is, if it is known from the adjustable spraying implement 7 that the implement is a fertilizer application implement, it selects the fertilization map data from the field map data 9 for field A. If the implement is a pest control implement, it selects the pest control map data from the field map data 9 for field A.

[0034] By doing this, if all of the above conditions are met, the control device 2 can automatically select and acquire the desired field map data, and the field map data can be automatically displayed on the display 3 (S2 in Figure 3), significantly reducing the burden on the worker.

[0035] In the above embodiment, the operations of each control device 2 shown in S1 of Fig. 3 are not limited to the order described above, and any operation may be performed first. For example, in the above example, the self-position is used first to select a field, and then information from the adjustable-size spraying machine 7 is used, but it is also possible to use information from the adjustable-size spraying machine 7 first, and then use the self-position.

[0036] Also, the check for the standby screen startup may be omitted.

[0037] Next, as a prerequisite for starting the operation of reading field map data, it may be possible to obtain the desired field map data while omitting conditions other than the connection of the information storage device 6 as described above (obtaining self-position data and checking the connection of the work implement).

[0038] For example, if specific field map data is already being displayed on the display 3, that specific field map data can be stored in the control device 2, or a file containing that specific field map data can be identified and stored, or a specific folder containing that specific file can be stored, and when the information storage device 6 is once disconnected from the control device 2 and then reconnected, it is possible to display information on the display 3 using the stored specific field map data, specific file, and specific folder simply by checking the connection of the information storage device 6 and its credentials. This is because there may be only one piece of field map data in that specific file, or there may be only one file and one piece of field map data in that specific folder.

[0039] For example, after working in field A in the morning using fertilization map data, the information storage device 6 is removed during lunch break, and then inserted again in the afternoon to use the fertilization map data in field A again.

[0040] Next, various inventions related to the present invention will be described.

[0041] (1) The field map data to be read is read from a file with a specific file name in the information storage device 6, which is preset in the control device 2.

[0042] (2) If the file read in (1) contains only one piece of field map data, it is displayed on the display 3.

[0043] (3) If the file read in (1) contains multiple pieces of field map data, they are displayed as a list on the display 3.

[0044] (4) The field map data to be read is read from a file in a specific folder in the information storage device 6, which is preset in the control device 2. This simplifies the file preparation process by simply placing the file in a specific folder. Multiple files can be read simultaneously.

[0045] (5) If the file read in (4) contains only one piece of field map data, that data is displayed on the display 3.

[0046] (6) If the file read in (4) contains multiple pieces of field map data, they are displayed as a list on the display 3.

[0047] (7) If the file loaded in (4) contains multiple field map data, the field map data containing the location information closest to the determined self-location among the location information of each loaded field map data is determined to be the field map data of the target field and displayed on the display 3.

[0048] (8) If the file loaded in (4) contains multiple field map data, the field map data whose center of gravity position, determined from the position information of each loaded field map data, is closest to the determined self-position is determined to be the map data of the target field and displayed.

[0049] (9) If the file loaded in (4) contains multiple field map data, the field map data that includes the determined current position within the map range created from the position information of each loaded field map data is determined to be the map data of the target field and is displayed.

[0050] (10) The map to be read is a file specified in a setting file in the information storage device 6, which is preset in the control device 2. By being able to specify the file to be read in the setting file, the user can freely specify the file to be used.

[0051] (11) If the file read in (10) contains only one piece of farm field map data, the read farm field map data is displayed on the display 3.

[0052] (12) If the file read in (10) contains multiple pieces of farm field map data, the read farm field map data are displayed on the display 3 as a list.

[0053] If there is no field map data to be loaded in the above steps, it will not be displayed.

[0054] (13) If a work machine is connected, a file with a specific file name that is preset in the control device 2 and stored in the information storage device 6 is read.

[0055] (14) If the file read in (13) contains only one piece of farm field map data, the read farm field map data is displayed on the display 3.

[0056] (15) If the file read in (13) contains only one piece of field map data, and the received implement type and the work content of the field map data correspond to each other, the read field map data is displayed on the display 3. For example, this is the case for a fertilizer application implement and fertilization map data.

[0057] (16) If the file loaded in (13) contains only one piece of field map data, the field map data will not be displayed if the received implement type and the work content of the field map data do not correspond, as in the case of a fertilizer application implement and pest control map data.

[0058] (17) If the file loaded in (13) contains multiple pieces of farm field map data, the loaded farm field map data is displayed as a list.

[0059] (18) If the file read in (13) contains multiple pieces of field map data, the field map data are displayed as a list.

[0060] (19) If the file read in (13) contains multiple pieces of field map data, only those pieces of field map data that correspond to the received implement type and the work content of the received implement type are displayed as a list on the display 3.

[0061] (20) If there is only one corresponding data in (19), the field map data is displayed.

[0062] (21) If the file read in (13) contains multiple pieces of field map data, the received implement type and the work content of the field map data do not correspond to each other and are not displayed.

[0063] (22) When a work machine is connected, a file in a specific folder in the information storage device 6 that is preset in the control device 2 is read.

[0064] (23) If the file read in (22) contains only one field map data, the field map data is displayed.

[0065] (24) If the file read in (22) contains only one piece of field map data, the read field map data is displayed if the received implement type and the work content of the field map data correspond to each other.

[0066] (25) If the file loaded in (22) contains only one piece of field map data, the field map data will not be displayed if the received implement type and the work content of the field map data do not correspond.

[0067] (26) If the file loaded in (22) contains multiple pieces of farm field map data, the loaded farm field map data is displayed as a list.

[0068] Note that Figure 4 shows the display when only a USB connection is used, Figure 5 shows the display when a USB connection is used and the standby screen is displayed, Figure 6 shows the display when a USB connection is used and an AG-PORT connection is displayed, and Figure 7 shows the display when a USB connection is used and the standby screen is displayed and an AG-PORT connection is displayed.

[0069] FIG. 8 is an algorithm analysis tree diagram for reading and displaying data under various combinations of USB connection, standby screen, and AG-PORT connection.

[0070] Also, if the map data for a field is only pest control map data, as in field B, it will not be displayed if the connected implement is a fertilizer application implement.

[0071] In the above embodiment, data such as information on the farm field position does not need to be stored in the server 5, but can be stored in the information storage device 6 itself. [Industrial Applicability]

[0072] The present invention is ideal for agricultural work machines that use field map data to perform various spraying operations, as it allows for the selection and display of optimal field map data easily and with fewer errors. [Explanation of symbols]
