[First Embodiment]
When performing farm work on a farm field, a work plan is often made with reference to past farm work results (referred to as work results), and farm work is often performed according to the work plan. The work plan is established based on the analysis result by analyzing the work results using a personal computer or the like before performing the farm work. Or when performing farm work, a farm worker (producer) may refer to the past work performance and decide simultaneously with farm work based on the referred work performance and the producer's know-how.

  In the agricultural work support system of the present invention, in order to be able to easily provide a work plan when performing farm work, first, a work record when farm work is performed in advance on a farm field is collected by a data collection device (data collection means). Then, the work plan is calculated and output to the agricultural machine based on the collected work results, or the collected work results are arranged and output to the agricultural machine working on the field.

Hereinafter, the farm work support system will be described in detail.
FIG. 1 shows an overall view of a farm work support system.
As shown in FIG. 1, the farm work support system 1 </ b> A includes a data collection device (data collection means) 2 that collects work results and a database 3 that collects and saves work results for each farm field. In addition, the farm work support system 1 includes work plan calculation means 4 that calculates a work plan based on work results stored in the database 3 and data output means 5 that outputs the work plan.

  The data collection device 2 is mounted on a combine 10 that is one of agricultural machines, and the database 3, the work plan calculation means 4, and the data output means 5 are provided in an external terminal 11 such as a personal computer. In this farm work support system 1, the work results of the combine 10 collected by the data collection device 2 are transmitted to the external terminal 11 via the portable terminal 12 and stored in the database 3 of the external terminal 11. Based on the work results stored in the database 3 of the external terminal 11, the work plan calculation unit 4 calculates the work plan, and the calculated work plan is transferred to the tractor 13 different from the combine 10 by the data output unit 5. Send.

  That is, as shown in FIG. 2, the farm work support system 1 </ b> A is a system that performs farm work in cooperation with one farm machine (combine 10) and another farm machine (tractor 13). Work results are collected when farming is performed with a machine (combine 10). Then, a work plan for working with another agricultural machine (tractor 13) is made using the work record in one agricultural machine (combine 10), and this work plan is output to the other agricultural machine (tractor 13). . In this agricultural work support system, as a matter of course, the agricultural machine is a wireless communication device capable of transmitting and receiving various data (for example, short-range wireless communication, such as WiFi (R), Bluetooth (R), ZigBee (R) Etc.), and can perform data communication with the portable terminal 12 and the external terminal 11.

  The data collection device 2 includes a nonvolatile memory (storage unit) 15. The storage unit 15 temporarily stores various work results when the combine 10 is operated. Specifically, the combine 10 is provided with a taste sensor 20 for detecting the protein of the harvested cereal and a yield sensor 21 for detecting the amount of harvested cereal. The protein (taste, protein content) detected by the taste sensor 20 and the yield (yield) detected by the yield sensor 21 are temporarily stored in the storage unit 15 as work results.

  The mobile terminal 12 is composed of a tablet PC, a smartphone having a telephone function, etc., and a positioning communication satellite for acquiring the wireless communication function for wirelessly communicating with various devices and the position of the mobile terminal 12. And a position detection function (position detection unit) 23 for detecting a position based on a signal from the signal 22. The position detection unit 23 includes a program stored in the mobile terminal 12.

  Specifically, the position detection unit 23 is for detecting a position by GPS or the like which is one of the satellite positioning systems, and a signal transmitted from the positioning satellite 22 (GPS satellite) (GPS satellite position and transmission). Time, correction information, etc.) are received, and the position (for example, latitude, longitude) of the portable terminal 12 is obtained based on the received signal. When the portable terminal 12 is mounted on the combine 10, the position of the portable terminal 12 becomes the position of the combine 10 (referred to as a work machine position). This work machine position is used to specify in which field the work results are collected (acquired).

  For example, when the user rides on the combine 10 with the portable terminal 12 and activates the combine 10, the data collection device 2 obtains the work result of the combine 10 and also obtains the work equipment position of the combine 10 by the portable terminal 12. Can do. In this way, since the work machine position when the work results are acquired is known, the field where the work results are collected can be identified by comparing the work machine position with the position of the field. The work record acquired by the combine 10 and the work machine position acquired by the portable terminal 12 are transmitted to the external terminal 11, and the external terminal 11 determines which field the work record is, and the work record for each field. Are stored in the database 3.

  As shown in FIG. 3A, in detail, when harvesting is performed by operating the combine 10, work results (protein, yield) are transmitted from the data collection device 2 to the portable terminal 12, and the work results are also displayed. The acquired data acquisition time is transmitted to the external terminal 11 via the portable terminal 12. On the other hand, as shown in FIG. 3A, the work machine position of the combine 10 and the time when the work machine position is acquired from the portable terminal 12 (position acquisition time) are also transmitted to the external terminal 11.

  As illustrated in FIG. 3B, when the external terminal 11 receives the work record, the data acquisition time, the work machine position, and the position acquisition time, the external terminal 11 compares the data acquisition time with the position acquisition time, and obtains the data acquisition time and the position. A work result table at the time when the acquisition time coincides with the work machine position is stored in the database 3 in association with the work result and the work machine position.

  Next, the external terminal 11 compares the work machine position in the result position table with the field map (latitude, longitude) indicating the position of the field, and associates the work result acquired by the combine 10 with the field on the field map. . For example, when the work machine position in the result position table and the field shown in the field map overlap each other (when the work machine position exists in the field on the field map), the work result corresponding to the work position overlapping the field Is determined to have been acquired in the overlapped field, and the overlapped field and the work performance are associated with each other.

Then, as shown in FIG. 4A, the external terminal 11 creates a first work result table T1 that associates the field number that identifies the overlapping field and the work result, and associates the field number and the work result. Then, the first work result table T1 is stored in the database 3.
Here, every year, when the harvest is harvested with the combine 10, the work results are collected, and if the work results are associated with the field, as shown in FIG. 4 (b), not only a single year but also several years. It is possible to create a second work result table T2 having minute work results. Further, the first work result table T1 and the second work result table T2 are a data group in which a plurality of work results (protein, harvest amount) exist for one farm field. FIG. As shown, average the protein in one field, use the average value as the representative value of the protein in the field, and calculate the yield (kg / 10a, 俵 / 10a) in the single field. A third work performance table T3 having (kg / 10a, 俵 / 10a) may be created in the database.

  The database 3 may include all of the first work result table T1, the second work result table T2, and the third work result table T3 described above, but the first work result table T1 and the second work result table T2. , Any work result table T2 of the third work result table T3 may be included. It should be noted that when the first work performance table T1, the second work performance table T2, and the third work performance table T3 are created, the data acquisition time (or position acquisition time) may be associated with each other and created in the database 3. By doing so, it is possible to confirm the date and time (work performance date and time) when the farm work is performed even at a later date, which is more convenient when performing the work plan.

  As described above, in the farm work support system 1, when the combine 10 performs farm work (harvesting) in the field B among a plurality of fields, it is possible to acquire work results when the farm work is performed in the field B. When the combine 10 performs farm work (harvesting) in the field D, the work results when the combine 10 farms in the field D can be acquired. The work results in the field B and the work results in the field D can be stored in the database 3 as a work result table.

  In addition, you may perform the preparation of the performance position table in which the work performance and the working machine position were linked | related with the portable terminal 12 instead of the external terminal 11. FIG. In this case, for example, when the farm work on the farm field is completed, the work record and the data acquisition time are collectively transmitted from the data collection device 2 to the portable terminal 12. The portable terminal 12 collates the data acquisition time transmitted from the data collection device 2 with the position acquisition time stored in advance when collecting work results. Then, similarly to the external terminal 11, the work result and the work machine position at the time when the data acquisition time and the position acquisition time match are associated with each other, and the data in which the work result and the work machine position are associated with each other are stored in the result position table. And If the actual position table created in this way is transmitted from the portable terminal 12 to the external terminal 11, the actual position table can be stored in the database 3.

Now, the work plan calculation means 4 calculates a work plan for each field based on the work results, and is composed of a program stored in the external terminal 11 or the like.
When the program constituting the work plan calculating means 4 is activated, as shown in FIG. 5, the display unit (monitor) of the external terminal 11 calculates a fertilization amount (for example, nitrogen fertilization amount) as one of the work plans. A setting input screen S1 for inputting information (field number, target yield, target taste value, yield weighting coefficient α, taste weighting coefficient β, reference fertilization amount S) necessary to do so is displayed.

  In the setting input screen S1, the field number designates the field for calculating the fertilization amount, the target yield sets the target yield in the designated field, and the target taste value indicates the designated field. This specifies the target taste in. The yield weighting coefficient α sets the importance of the yield when calculating the fertilization amount, and the taste weighting coefficient β sets the importance of the taste when calculating the fertilization amount. Yield and taste are in a contradictory relationship. Increasing the importance (α) of the yield decreases the importance (β) of the taste, and increasing the importance (β) of the taste increases the importance of the yield. (Α) decreases. When setting the nitrogen fertilization amount (work plan), the producer sets the yield weighting coefficient α and the taste weighting coefficient β in consideration of the balance between the conflicting yield and taste.

  The reference fertilization amount S is obtained, for example, in consideration of the nitrogen amount already existing in the field (nitrogen amount per one field) in determining the nitrogen fertilization amount. The amount of nitrogen in the field is subtracted from the amount of nitrogen, and a reference fertilization reference amount S is obtained. For example, when the standard amount of nitrogen desired per field is 12.0 kg / 10a and the amount of nitrogen in the field is 8.50 kg / 10a, the fertilization reference amount S is 12.0 kg / 10a. The value obtained by subtracting 8.50 kg / 10a from the value is 3.50 kg / 10a. Note that the reference fertilization amount S is not limited to the above-described calculation method, and for example, the producer may set the cereal variety.

The work plan calculation means 4 includes information (field number, target yield, target taste value, yield weighting coefficient α, taste weighting coefficient β) input to the setting input screen S1, and taste and yield (work) stored in the database 3. Based on the actual results), the amount of nitrogen fertilizer sprayed on the designated field is calculated as a work plan.
Hereinafter, the work plan calculation means 4 will be described in detail.

The work plan calculation means 4 includes a yield difference calculation unit 30, a taste difference calculation unit 31, a yield difference correction unit 32, a taste difference correction unit 33, and a fertilizer application amount setting unit. The yield difference calculation unit 30, the taste difference calculation unit 31, the yield difference correction unit 32, the taste difference correction unit 33, and the fertilizer application amount setting unit 34 are configured by a program or the like.
The yield difference calculation unit 30 calculates the yield target value (target yield) Y _O entered in the setting input screen S1 and the actual yield value (actual yield) stored in the database 3 based on the following equation (1). ) to calculate the yield being the difference between Y _P.

  Specifically, when the field number is input on the setting input screen S1, the yield difference calculation unit 30 obtains the previous year's yield in the field corresponding to this field number from the database 3, and the previous year's yield as the actual yield Yp. adopt. The yield difference calculation unit 30 may obtain the yields of a plurality of years instead of obtaining the yields of the previous year from the database 3, and may obtain the average value of the obtained yields of the plurality of years as the actual yield Yp. The weighted average value calculated by weighting the yield may be used as the actual yield Yp.

Then, the yield difference calculation unit 30 calculates the yield difference by subtracting the actual yield Yp from the target yield Y _O input on the setting input screen S1, as shown in Expression (1).
Taste difference calculation unit 31, based on equation (2), the actual value of taste that is stored in the database 3 (actual taste value) and Q _P, protein content, which is input to the set input screen S1 of (taste value) A taste difference which is a difference from the target value (target taste value) Q _O is calculated.

Specifically, when the field number is input on the setting input screen S1, the taste difference calculation unit 31 acquires the previous year's taste in the field corresponding to this field number from the database 3 in the same manner as the yield difference calculation unit 30. and, to adopt the previous year of taste as the actual taste value Q _P. Incidentally, taste difference calculation unit 31, instead of obtaining the year of the taste from the database 3 to obtain a multi-year taste, to the average value of the multi-year taste obtained may be used as actual taste value Q _P, each a weighted average value calculated by performing weighting the yield of the year may be used as the actual taste value Q _P.

The yield difference calculating section 30, as shown in equation (2), by subtracting the target palatability value Q _O input from the actual taste value Q _P to the setting input screen S1, to calculate a taste difference.
The yield difference correction unit 32 multiplies the yield difference (Y _O −Y _P ) calculated by the yield difference calculation unit 30 by the yield weighting coefficient α input on the setting input screen S1, as shown in Equation (3). Is used to calculate the importance of the yield difference.

As shown in Expression (4), the taste difference correction unit 33 multiplies the taste difference (Q _P −Q _O ) calculated by the taste difference calculation unit 31 by the taste weighting coefficient β input on the setting input screen S1. Thus, the importance of the taste difference is calculated.

The fertilizer application amount setting unit 34 calculates the corrected yield difference α (Y _O −Y _P ) calculated by the yield difference correcting unit 32 and the corrected taste difference β (Q _P −Q _O ) calculated by the taste difference correcting unit 33. By applying the equation (5), the amount of nitrogen fertilization N (kg / 10a) is obtained.

Now, the unit of fertilization reference amount S is “kg / 10a”, the unit of yield difference (Y _O −Y _P ) is “俵 / 10a”, and the unit of taste difference (Q _P −Q _O ) is “ %, And the fertilization reference amount S, the yield difference (Y _O −Y _P ), and the taste difference (Q _P −Q _O ) are values of different units, but the formula as shown in the formula (5) The amount of nitrogen fertilization N (kg / 10a) can be determined. Referring to equation (5), α (Y _O −Y _P ) is a correction term for correcting the fertilization reference amount S from the viewpoint of yield, and should be increased or decreased to achieve the target yield Y _O. Can be treated as nitrogen fertilizer. Β (Q _P −Q _O ) is a correction term for correcting the fertilization reference amount S from the viewpoint of the taste value, and is a nitrogen fertilization amount that should be reduced or increased in order to achieve the target taste value Q _O. Can be handled.

Therefore, as shown in the formula (5), the yield difference α (Y _O −Y _P ) is added to the fertilization reference amount S, and the taste difference β (Q _P −Q _O ) is subtracted. Thus, the nitrogen fertilization amount N can be obtained by taking into account the increase / decrease in the amount of nitrogen fertilization due to the yield difference α (Y _O −Y _P ) and the increase / decrease in the amount of nitrogen fertilization due to the taste difference β (Q _P −Q _O ). . When determining the amount of nitrogen fertilization, the units of the target yield, the actual yield, the actual taste value, the target taste value, and the fertilization reference amount S may be ignored, and these values may be used as they are.

  In formula (5), in determining the nitrogen fertilization amount N, the yield weighting coefficient α (0 ≦ α ≦ 1) and the taste weighting coefficient β (0 ≦ β ≦ 1) are set in order to set the balance between yield and taste. The sum of (α + β) is 1. By setting “α + β = 1”, if one of the yield and the taste is heavily weighted, the other weight becomes small, and a result that more appropriately reflects the contradictory relationship between the yield and the taste can be obtained. The yield weighting coefficient α and the taste weighting coefficient β are preferably set so as to be both positive values.

In the present embodiment, the yield is represented by the number of pods harvested per piece, but the yield may be represented by the weight (kg) harvested per piece. When representing the targeted yield Y _O and actual yield Y _P weight per first reaction the (kg / 10a) as a unit, by applying the targeted yield Y _O and actual yield Y _P as it units formula (1), obtained By dividing the yield difference by 60 kg which is the weight per 1 kg, the unit of yield difference “kg / 10a” obtained by the formula (1) can be converted to the unit “俵 / 10a”.

When the nitrogen fertilization amount N is determined by the equation (5), as shown in FIG. 6, the nitrogen fertilization amount N (kg / 10a) is associated with the field information (field number, field name, field area, etc.) regarding the field, Each field is stored in the database 3.
Thus, in the agricultural work support system 1, when harvesting grains such as rice and wheat with the combine 10, the data collection device 2 mounted on the combine 10 can collect work results such as harvest and taste. The collected work results are stored in the database 3 of the external terminal 11, and a work plan that is the amount of nitrogen fertilization can be set for each field by the work plan calculation means 4. Since the work plan (nitrogen fertilization amount) is stored in the database 3 for each field, it can be used when fertilization is performed in the field.

The farm work support system 1 includes data requesting means 6 that requests a work plan (nitrogen fertilization amount) and data output means 5 that outputs the work plan (nitrogen fertilization amount) requested by the data requesting means 6. . The data requesting means 6 is composed of, for example, a program for the portable terminal 12, and the data output means 5 is composed of a program for the external terminal 11.
When a program constituting the data requesting unit 6 is started, as shown in FIG. 7, a request input for inputting information (a field number) necessary for requesting a work plan to the display unit (monitor) of the portable terminal 12 A screen S2 is displayed. The field number in the request input screen S2 designates a field for which a work plan is to be acquired, and the producer inputs the field number corresponding to the field to be spread when the fertilizer is spread by the tractor 13. .

  When the field number is input to the request input screen S2, the data requesting means 6 transmits a request signal for requesting the field number and work plan to the personal computer having the database 3 by wireless communication or the like. When the data output means 5 receives the field number and the request signal from the data request means 6, the data output means 5 refers to the database 3 to extract the nitrogen fertilization amount corresponding to the field number, and extracts the extracted nitrogen fertilization amount and the field information (field number). , Field name, field area, etc.) are transmitted to the portable terminal 12. When the portable terminal 12 receives the nitrogen fertilization amount and the field information, the mobile terminal 12 displays the nitrogen fertilization amount and the field information on the display unit.

  For example, when fertilizer is spread by the fertilizer spreader 37 connected to the tractor 13, if the producer carries the portable terminal 12 and gets on the tractor 13, the amount of nitrogen fertilizer applied to the producer who gets on the tractor 13 can be set. You can be notified. The producer can calculate the amount of fertilizer to be spread on the field with reference to the amount of nitrogen fertilizer displayed on the mobile terminal 12, field information (field area, etc.), and the nitrogen component value% contained in the fertilizer. By manually manipulating the fertilizer application device 37 so that the amount of fertilizer is applied, fertilization corresponding to the work plan can be performed.

  In the above-described embodiment, the amount of nitrogen fertilization (work plan) is displayed on the mobile terminal 12, but it is installed around the driver's seat of an agricultural machine (for example, the tractor 13) that performs work on the field. You may make it display a nitrogen fertilization amount (work plan) on a display apparatus (for example, meter panel). In this case, the work plan and the field information may be transmitted from the portable terminal 13 or the external terminal 11 to the tractor 13, and the display device of the tractor 13 displays the work plan and the field information after receiving the work plan and the field information. do it.

  Alternatively, the mobile terminal 12 outputs information necessary for nitrogen fertilization (the field area, the nitrogen component value included in the fertilizer) among the nitrogen fertilization amount and the field information to the control device 38 that controls the fertilizer spraying device 37, Fertilization may be automatically performed under the control of the control device 38. In this case, when receiving the nitrogen fertilization amount and the field area through the mobile terminal 12, the control device 38 obtains the fertilization amount to be applied to the field from the nitrogen fertilization amount, the field area, and the nitrogen component value contained in the fertilizer. The fertilizer application device 37 is controlled. The nitrogen component value% contained in the fertilizer is preferably input to the mobile terminal 12.

  For example, if the nitrogen fertilization amount that is the work plan is “3.885475 kg / 10a”, the field area is 10a, and the nitrogen content of the fertilizer to be sprayed is 14%, the nitrogen fertilization amount (3.885475 kg / 10a) The value obtained by dividing by 14%, approximately 27.5340 kg / 10a, is the amount of fertilizer applied to the field. The control device 38 adjusts the amount of fertilizer applied per unit time by the fertilizer spraying device 37 according to the travel distance in the field so that the amount of fertilization in the field becomes 27.5340 kg / 10a, or the tractor 13 in the field. The fertilizer application amount per unit time by the fertilizer spraying device 37 is adjusted according to the speed of. In addition, since what is necessary is just to control the fertilizer spraying apparatus 37 so that it may become the amount of nitrogen fertilization which is a work plan, control etc. of the fertilizer spraying apparatus 37 are not limited to what was mentioned above.

  As described above, according to the farm work support system 1, when the fertilizer is spread by the tractor 13, for example, if the producer has the portable terminal 12 and gets on the tractor 13, the fertilizer can be easily manually or automatically according to the work plan. Can be sprayed. In summary, in the agricultural work support system 1, one agricultural machine (combine 10) equipped with the data collection device 2 and another agricultural machine (tractor 13) that performs agricultural work different from the one agricultural machine (combine 10). Agricultural work can be carried out in cooperation with each other. In particular, the database 3 that collects the work results collected by one agricultural machine (combine 10) for each field, the work plan calculation means 4 that calculates the work plan for each field based on the work results of the database 3, and other Since the agricultural machine (tractor 13) is provided with the data output means 5 for outputting a work plan corresponding to the field, the result (work result) of the agricultural work by one agricultural machine (combine 10) can be obtained from other agriculture. It can be used for farm work by the machine (tractor 13), and farm work by the tractor 13 can be easily performed.

  In the embodiment described above, the mobile terminal 12 and the external terminal 11 are configured separately, but the function of the external terminal 11 may be provided in the mobile terminal 12. That is, as shown in the farm work support system 1B of FIG. 8, the database 3, work plan calculation means 4, data request means 6, and data output means 5 may be provided in the portable terminal 12. In this case, by replacing the external terminal described above with a mobile terminal, the operation of the mobile terminal 12 is performed, and thus description thereof is omitted.

Moreover, you may provide the function of the portable terminal 12 in one agricultural machine (combine). For example, the position detection unit 23 of the portable terminal 12 and the function of the actual position table may be provided in the combine 10, and the actual position table may be transmitted from the combine 10 to the external terminal 11.

Etc.) is displayed. The field number in the request input screen S3 designates a field for which work results are desired to be acquired, and the producer inputs the field number corresponding to the field to be spread when the fertilizer is spread by the tractor 13. . The year in the request input screen S3 designates the year to be acquired among the work results of a plurality of years, and the presence / absence of an average sets whether to obtain the work results as an average value. .

  When the field number, year, and average presence / absence are input to the request input screen S3, the data requesting means 40 transmits the field number, year, and average presence / absence to the personal computer having the database 3 by wireless communication or the like. When the data output means 41 receives the field number, year, and average presence / absence from the data request means 6, the data output means 41 refers to the database 3 to extract the work results corresponding to the field number, year, and average presence and the extracted work The results and the field information (field number, field name, field area, etc.) are transmitted to the mobile terminal 12. When the portable terminal 12 receives the work record and the farm field information, the portable terminal 12 displays the work record and the farm field information on the display unit.

For example, when the fertilizer is sprayed by the fertilizer spraying device 37 connected to the tractor 13, if the producer carries the mobile terminal 12 and gets on the tractor 13, the producer who gets on the tractor 13 sees the work results and the field information. be able to. The producer can make a work plan with reference to the work results and the field information displayed on the mobile terminal 12.
In the second embodiment, the function of the external terminal 11 may be provided in the mobile terminal 12 as in the first embodiment.
[Third Embodiment]
The third embodiment is a modification of the first embodiment, and adds a parameter for calculating a work plan. Differences from the first embodiment will be described.

  As shown in FIG. 11, in the database 3 in the third embodiment, the field characteristics (characteristics) that may affect the amount of nitrogen expressed in the field, and the characteristics affect the nitrogen amount. A field characteristic table T4 associated with the field characteristic coefficient C whose degree has been evaluated is stored. The characteristics and the field identification coefficient C are set in advance in consideration of past work results and the like.

  When the program constituting the work plan calculation means 4 is started, the field number, target yield, target taste value, yield weighting coefficient α, taste weighting coefficient are displayed on the display unit (monitor) of the external terminal 11 as shown in FIG. A setting input screen S4 for inputting β, reference fertilizer amount S, and characteristics is displayed. When “previous crop, high yielding variety” is selected as the characteristic, 1.2 is set as the field identification coefficient C.

The fertilizer application amount setting unit 34 also considers the field specific coefficient C in addition to the target yield Y _O , the target taste value Q _P , the yield weighting coefficient α, the taste weighting coefficient β, and the reference fertilizer application quantity S, and these are expressed by Equation (6) The amount of nitrogen fertilization is calculated by applying to

According to this embodiment, since the amount of nitrogen fertilization can be calculated in consideration of the characteristics of the field, fertilization more suitable for the field can be performed.
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. In the embodiment described above, the data collection device 2 is mounted on the agricultural machine, but the data collection device 2 may not be mounted on the agricultural machine. In this case, the work results collected by the data collection device 2 may be configured to be transmitted to the mobile terminal 12 or the external terminal 11, and the position is detected by the data collection device 2 based on the data from the positioning satellite 22. It is preferable to provide a position detection unit 23 that performs the above.

  In the embodiment described above, one agricultural machine is the combine and the other agricultural machine is the tractor, but the present invention is not limited to this. For example, one agricultural machine may be a tractor, another agricultural machine may be a transplanter, one agricultural machine may be a transplanter, and another agricultural machine may be a tractor.
