Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an overall view of a farm work information management system.
As shown in FIG. 1, the farm work information management system 1 collects farm work information (referred to as farm work information) when farm work is performed in the field 3 using the farm machine 2 such as a combine or a rice transplanter. The collected farm work information is managed for each field.

  Specifically, the agricultural work information management system 1 collects agricultural work information of the agricultural machine 1 while detecting the working position of the agricultural machine 1 using a satellite positioning system (Global Positioning System, Positioning system, etc.). The collected farm work information and work position are transmitted to the farm work information management apparatus 6 configured from a server or the like using a communication device such as a portable terminal, and the farm work information management apparatus 6 sorts the farm work information for each farm field. The farm work information arranged for each farm field can be used, for example, for a work plan when farming in the farm 3 or for creating a daily work report for performing farm work.

First, taking a combine as an example, the configuration of an agricultural machine will be described.
FIG. 13 shows an overall view of the combine.
The combine 2 is configured to include a driver's seat 13, an engine 14, a threshing device 15 for threshing processing, a glen tank 16 for storing threshed crops, and the like on a machine body 12 having a pair of left and right traveling devices 11. On the front side of the machine body 12, a cutting unit 17 that cuts crops (for example, grains) is provided.

  As shown in FIGS. 1 and 2, the combine 2 includes means for measuring the water content, taste, yield, etc. of the crop as farm work information when the farm work is performed. Specifically, the combine 2 includes a moisture measuring unit 20 that measures the amount of moisture contained in the crop, a taste measuring unit 21 that measures the taste of the crop, and a yield measuring unit 22 that measures the crop yield. I have. The moisture measuring unit 20 and the taste measuring unit 21 are provided inside the Glen tank 16 or around the Glen tank 16.

The taste measurement unit 21 irradiates the crop with near-infrared light, analyzes the absorption spectrum based on the spectral analysis of the transmitted light, and obtains the amount of components such as protein contained in the crop based on the analysis result. The harvest amount measuring unit 22 is configured by a load cell or the like.
As shown in FIG. 2A, in the farm work information, moisture and taste are measured by putting a part of the crop put in the glen tank 16 into the measurement case 23 and the moisture of the crop put in the measurement case 23. And the taste is measured by the moisture measuring unit 20 and the taste measuring unit 21.

As shown in FIG. 2B, the crop in the measurement case 23 is placed in the Glen tank 16 when the measurement is completed. The harvest amount is obtained by measuring the weight of the Glen tank 16 by the harvest amount measuring unit 22 and converting the weight of the Glen tank 16 into the harvest amount when the Glen tank 16 is filled with crops. .
That is, the moisture and taste are measured after storing the crop in the measurement case 23 and securing the crop for sampling, and then measuring the crop for sampling. On the other hand, the harvest amount is when the crop in the Glen tank 16 is full. Since the weight of the Glen tank is measured in a similar manner, the sampling period for moisture and taste is different from the sampling period for yield, and the sampling period for moisture and taste is shorter than the sampling period for yield.

The combine 2 is provided with a position detection device 25 that receives a signal from a GPS satellite or the like, which is one of satellite positioning systems, and detects a position (for example, latitude and longitude). The position detection device 25 can detect the work position when the combine 2 performs the farm work.
The position detection device 25 may be configured by a mobile terminal (tablet PC, smartphone having a telephone function, or the like) that can detect a position by receiving a signal from a GPS satellite or the like. In this case, an operator who operates the combine 2 may bring the mobile terminal and operate the combine 2 or install the mobile terminal in the combine 2 and set the position of the mobile terminal as the work position of the combine 2. .

Here, when the measurement of the moisture and taste of the crop is completed, the work position of the combine 2 at the time of measuring the moisture and the taste (at the end of the measurement) is related to the moisture and the taste, and the moisture and the taste control the combine 2 To the control device 26 or the wireless communication device 27 provided in the combine 2. Further, when the measurement of the crop yield is completed, the work position of the combine 2 at the time of the harvest measurement (at the end of the measurement) is associated with the harvest, and the harvest is stored in the control device 26 or the wireless communication device 27. Sent.

The farm work information (moisture, taste, yield, etc.) and work position are temporarily stored in the control device 26 or the wireless communication device 27. The farm work information and the work position temporarily stored in the control device 26, the wireless communication device 27, and the like are transmitted to the farm work information management device 6 via the wireless communication device 27 that performs wireless communication with the outside, for example. .
As shown in FIG. 3, when the farm work information management apparatus 6 receives moisture, taste, harvest amount, and work position, the farm work information management apparatus 6 sequentially stores moisture in the information storage unit 30 provided in the farm work information management apparatus 6 at predetermined intervals. Storing (storing) the taste, yield, and work position. That is, a plurality of pieces of farm work information (moisture, taste, yield) are stored in the information storage unit 30 at a predetermined interval (work position detection interval). For example, 24 pieces of farm work information are stored in the information storage unit 30 while the combine 2 moves from the first position (longitude 34.55989, latitude 135.467494) to the second position (longitude 34.56449, latitude 135.472094). Become.

The accuracy of the work position (position accuracy) that can be detected by the position detection device 25 is about several tens of centimeters to several meters, and the high performance is actually several centimeters. As described above, although the position detection device 25 having a positional accuracy of several centimeters has been developed, the one having a positional accuracy of several centimeters is very expensive and may be adopted as a device for detecting the combine working position. difficult.
That is, the position detection device 25 employed in the combine 2 or the like often has a position accuracy (measurement error) of several tens of centimeters to several meters, and the combine 2 is positioned using a work position including these errors. It is difficult to specify the farm 3 to be performed by the conventional technique.

Further, as shown in FIG. 4, the field 3 is generally rectangular and is regularly arranged vertically and horizontally, so there is little difference in shape. It is difficult to identify the field only by For example, the case where the farm work by the combine 2 is performed in the field A among the field A, the field B, the field C, and the field D is considered.
Immediately after the start of farm work in the field A, the combine 2 is located on the entrance side of the field 3, but the entrance of the field 3 is close not only to the field A but also to the field B, so the position detection device 25 Thus, even if one work position of the combine 2 is detected, an error is included in the work position by the position detection device 25. Therefore, when only one work position is seen, the actual combine 2 is It is difficult to determine whether the user is in the farm B or the farm B.

Therefore, in the present invention, the correspondence (relevance) between the farm work information and the farm field 3 is appropriately determined by performing processing as described later using a plurality of work positions and map data. In particular, in the present invention, the farm work information corresponding to the farm field is determined using the contour line and the work position of each farm field obtained from the map data.
The farm work information management apparatus and farm work information management system of the present invention will be described below.

  The farm work information management device 6 collects farm work information transmitted from the combine 2 and arranges the farm work information offline after collection. For example, a personal computer owned by a user, a management owned by a farm management company, etc. It consists of servers and so on. When a farm work (harvesting work) is performed in a predetermined field 3 using the combine 2, farm work information when the farm work is automatically performed is automatically collected (saved) in the control device 26 of the combine 2. The farm work information stored in the combine 2 (control device 26) is transmitted to the farm work information management apparatus 6.

  Note that any method may be used for transmitting the farm work information to the farm work information management apparatus 6. For example, the farm work information may be automatically transmitted to the farm work information management apparatus 6 periodically (every day, every week), or the operator operates a display device provided around the driver's seat of the combine 2. Thus, the farm work information to be transmitted may be determined and the farm work information or the like may be transmitted to the farm work information management device 6 via the wireless communication device 27, or the portable terminal or the like that wirelessly communicates with the wireless communication device 27 may be manually operated. The farm work information or the like may be transmitted to the farm work information management apparatus 6 via the portable terminal, or may be transmitted by other methods.

The farm work information management device 6 includes an information storage unit 30 that stores farm work information and work positions,
A map data storage unit 31 that stores map data of a plurality of farm fields 3 and an information organizing unit 32 that organizes farm work information for each farm field using work positions and map data are provided.
The information storage unit 30 is configured by a non-volatile memory or the like, and as described above, a plurality of farm work information (moisture, taste, yield) and work position (latitude, longitude) transmitted from the combine 2, and farm work The work position at the time of going is stored in association with it.

Similar to the information storage unit 30, the map data storage unit 31 is also composed of a non-volatile memory or the like, and stores map data relating to a plurality of fields 3 (for example, the latitude and longitude of the field 3, the contour of the field 3, etc.). To do.
The information organizing unit 32 includes a CPU, a program, and the like, and organizes the farm work information using farm work information (moisture, taste, yield), work position (latitude, longitude), map data, and the like. For example, among the collected farm work information, the information organizing unit 32 first divides each farm work information for each field and sorts the divided farm work information as necessary. For example, using a plurality of pieces of farm work information divided for each field, the moisture and taste for each field are obtained, and the harvest amount for each field is obtained. The information organizing unit 32 organizes farm work information by various methods such as mathematics, but any method may be used for organizing the information.

As described above, since the field 3 is often formed in a rectangular shape (quadrangle), when performing the farm work (crop harvesting) with the combine 2, the shape of the field 3 is taken into consideration. The travel route is determined.
The moving route of the combine 2 in the agricultural field will be described with reference to FIG. In the description of FIG. 5, when viewing the field, the side located on the right side and extending up and down on the paper surface is referred to as “right vertical side portion”, and the side located on the left side and extending up and down on the paper surface is referred to as “left vertical side portion. The side located on the upper side and extending to the left and right of the paper surface is referred to as “upper horizontal side portion”, and the side located on the lower side and extending to the left and right of the paper surface is referred to as “lower horizontal side portion”.

As shown in FIG. 5, in the harvesting of the crop by the combine 2, the combine 2 first performs row cutting while proceeding from the entrance of the field 3 along the edge (right vertical side portion R <b> 1). When the combine 2 travels to the opposite side of the entrance, it turns 90 degrees on the opposite side, proceeds along the upper horizontal side U2 of the field 3 that is substantially orthogonal to the right vertical side R1 of the field 3, and performs horizontal cutting.
When the horizontal cutting around the upper horizontal side U2 is completed, the cutting is performed while proceeding along the left vertical side L1 substantially parallel to the right vertical side R1 of the field 3. When the cutting in the vicinity of the left vertical side portion L1 is completed, the direction of 90 degrees is changed, and the horizontal cutting is performed while proceeding along the lower horizontal side portion D2 substantially parallel to the upper horizontal side portion U2 of the field 3.

That is, when harvesting a crop with the combine 2, the crop is first harvested while turning counterclockwise along each side (contour line E) of the field 3 from the entrance of the field 3, and the contour line is drawn inside the field 3. After one round along E, the crop is harvested while moving counterclockwise in the field 3 in the same manner.
That is, when harvesting crops (agricultural work) using the combine 2, first, since one round is taken along the contour line E of the field 3, the locus of the work position of the combine 2 when the farm work is performed is It is considered that it substantially coincides with the contour line E.

In the present invention, paying attention to the relationship between the movement of the combine 2 when the farm work is performed in the field 3 and the contour line E of the field, it is determined appropriately which field 3 the farm work information corresponds to. Are organized by field.
FIG. 6 shows an example of the movement track of the farm 2 and the farm B adjacent to each other and the combine 2. Consider a case where the combine 2 is moving along the right vertical side R1 of the field A.

When the combine 2 is moving along the right vertical side R1 of the field A, the combine 2 is in a position close to the left vertical side L1 of the field B adjacent to the right vertical side R1 of the field A. Therefore, it is difficult to determine whether the combine 2 is in the field A or the field B even if only the movement locus of the work position of the combine 2 stored in the information storage unit 30 is viewed.
However, the combine 2 changes its direction at the corner of the field A, moves along the upper horizontal side U2 of the field A, and moves away from the field B. Therefore, the combine 2 moves along the right vertical side R1 of the field A. Combine 2 when moving along the upper horizontal side U2 in addition to the movement trajectory Q when moving
It is possible to distinguish whether the combine 2 is located on the field A or the field B by looking at the movement locus Q of the work position.

  That is, when it is desired to determine which side the combine 2 is in among the fields (the fields A and B), for example, the right vertical side R1 of the field A extending in one direction (vertical direction) and the left of the field B The vertical side portion L1 is extracted, and the upper horizontal side portion U2 and the upper horizontal side portion U2 of the agricultural field A that intersect (orthogonal) one direction and extend in the other direction are extracted. According to the relationship between the right vertical side R1 of A, the left vertical side L1 of the field B, the upper horizontal side U2 of the field A, the upper horizontal side U2 of the field B, and the work position stored in the information storage unit, Can be identified.

  When the relative distance (deviation amount) between each work position of the combine 2 that moves the field A and the right vertical side R1 of the field A in the right vertical side part R1 of the field A is calculated, The amount tends to be shown in FIG. Further, when the amount of deviation between each work position of the combine 2 that moves the field A and the left vertical side L1 of the field B in the left vertical side part L1 of the field B is calculated, The tendency shown in FIG.

That is, as shown in FIG. 7A, the amount of deviation between the right vertical side R1 of the field A and the work position and the amount of deviation between the left vertical side L1 of the field B and the work position have the same tendency. Show.
On the other hand, when a relative distance (deviation amount) between each work position of the combine 2 that moves the field A and the upper side part U2 of the field A is obtained along the upper side part U2 of the field A (horizontal section). The deviation amount tends to be shown in FIG.

In addition, when the amount of deviation between each work position of the combine 2 that moves the field A and the upper side part U2 of the field B is obtained along the upper side part U2 of the field B (lateral section), the amount of deviation is obtained. FIG. 7B shows the tendency.
That is, as shown in FIG. 7B, the amount of deviation between the upper horizontal side portion U2 of the field A and the work position and the amount of deviation between the upper horizontal side portion U2 of the field B and the work position tend to be different. The amount of deviation between the upper horizontal side portion U2 of the farm field B and the work position increases.

As described above, in a plurality of farm fields (farm fields A and B), the tendency of the shift amount between the common vertical side (first side) and the work position is compared, and the common horizontal side (second side) ) And the tendency of deviation between the work positions, it is possible to specify the field where the combine 2 farmed.
Furthermore, it demonstrates in detail with the operation | movement of the information organization part 32. FIG.

The information organizing unit 32 includes a side extracting unit 40, a deviation amount calculating unit 41, and an information correspondence determining unit 42. The side extraction unit 40, the deviation amount calculation unit 41, and the information correspondence determination unit 42 are configured by a CPU, a program, and the like.
The edge extraction unit 40 links the farm work information stored in the information storage unit 30 to the farm field on which the farm work has been performed, so that a plurality of farm fields 3 and the contour lines E of each farm field 3 (simply referred to as the contour line E). Are extracted from the map data.

Specifically, first, the edge extraction unit 40 refers to the work position in the information storage unit 30. For example, as illustrated in FIG. 6, when the locus of the work position in the information storage unit 30 is along the contour line E of the farm field A (one farm field) located on the left side, the edge extraction unit 40 selects the farm field A. Candidates for farm work. A field that is a candidate for performing farm work is called a candidate field.
In addition to the field A, the side extraction unit 40 also sets a field B (another field) located on the right side of the field A and adjacent to the field A as a candidate field. For convenience of explanation, the field A and the field B shown in FIG.

When the extraction of the candidate field is completed, the side extraction unit 40 proceeds to a process of extracting the contour line E of the candidate field (contour line extraction process).
In the contour line extraction process, first, among the four contour lines E (the right vertical side portion R1, the left vertical side portion L1, the upper horizontal side portion U2, and the lower horizontal side portion D2) of the field A, the movement trajectory Q of the work position. And at least two sides having different directions are extracted. As described above, in the field A, the right vertical side portion R1 extending in one direction and close to the movement locus Q and the upper horizontal side portion U2 extending in a direction intersecting (orthogonal to) one direction and close to the movement locus Q are arranged. Extract.

Next, in the contour line extraction process, the four contour lines E (the right vertical side portion R1) of the field B are the same as the field A.
, The left vertical side portion L1, the upper horizontal side portion U2, and the lower horizontal side portion D2) are extracted from at least two side portions that are adjacent to the movement locus Q of the work position and have different directions. In the field B, a left vertical side L1 extending in one direction and close to the movement locus Q and an upper horizontal side U2 extending in a direction intersecting (orthogonal) with one direction and close to the movement locus Q are extracted.

That is, the side extraction unit 40 extracts a common side (longitudinal side portion) that is close to the work position and extends in one direction in the field A and the field B that are candidate fields, and extends in a direction intersecting with one direction. Extract common sides (lateral sides). Hereinafter, the common vertical side portion extracted by the side extraction unit 40 is referred to as a first side portion, and the common horizontal side portion is referred to as a second side portion.
When the extraction of the first side and the extraction of the second side are completed in the fields A and B, the side extraction unit 40 extracts the position information (latitude and longitude) of the first side from the map data. The position information (latitude, longitude) of the second side is extracted from the map data.

The deviation amount calculation unit 41 includes a first side deviation amount calculation unit 41a and a second side deviation amount calculation unit 41b.
The first side deviation amount calculation unit 41a obtains a first side deviation amount that is a deviation amount between the first side portion and the work position for each candidate farm. Specifically, as described above, since the first side in the field A is the right vertical side R1, the first side shift amount calculation unit 41a uses the position information of the right vertical side R1 of the field A. A first side shift amount (referred to as a first side shift amount for the field A) between the right vertical side portion R1 and each work position in the vertical section is obtained.

Moreover, since the 1st edge part in the agricultural field B is the left vertical edge part L1, the 1st edge deviation | shift amount calculating part 41a uses the position information of the left vertical edge part L1 of the agricultural field B, and the said left vertical edge part L1 And a first side deviation amount (referred to as a first side deviation amount for the farm B) with respect to each work position in the vertical section.
The second side deviation amount calculation unit 41b obtains a second side deviation amount that is a deviation amount between the second side portion and the work position for each candidate field. Specifically, as described above, since the second side portion in the field A is the upper horizontal side portion U2, the second side deviation amount calculation unit 41b uses the position information of the upper horizontal side portion U2 in the field A. A second side shift amount (referred to as a second side shift amount for the field A) between the upper horizontal side portion U2 and each work position in the horizontal section is obtained.

Moreover, since the 2nd side part in the agricultural field B is the upper horizontal side part U2, the 2nd side deviation | shift amount calculating part 41b uses the positional information on the upper horizontal side part U2 of the agricultural field B, and the said upper horizontal side part U2 And a second side deviation amount (referred to as a second side deviation amount for the field B) with each work position in the horizontal section.
In the calculation of the shift amount, the work position of the same vertical section is used for the first side (vertical side), and the work of the same horizontal section is used for the second side (horizontal side). Position is used. Further, when attention is paid to one side (vertical side or horizontal side), there are a plurality of pieces of position information indicating the one side, and therefore, from each position information on the one side to one work position. It is preferable that the average value of the distances be the contour shift amount of each work position. In other words, it is preferable that an average value of differences between one work position and a plurality of pieces of position information (information indicating one side) is set as a shift amount (contour shift amount) corresponding to each work position.

As described above, the shift amount calculation unit 41 (the first side shift amount calculation unit 41a and the second side shift amount calculation unit 41b) performs four types of shift amounts (the first side shift amount for the field A and the first for the field B). 1 side deviation amount, second side deviation amount for field A, and second side deviation amount for field B) are obtained.
The information correspondence determination unit 42 includes a first side shift amount (a first side shift amount for the field A, a first side shift amount for the field B) and a second side shift amount (a second side shift for the field A) in each field. On the basis of the amount, the second side displacement amount for the farm B), it is determined which farm field the farm work information corresponding to the work position corresponds to (determines which farm the combine 2 has worked on). The information correspondence determination unit 42 includes a first side shift amount comparison unit 45, a second side shift amount comparison unit 46, and an agricultural field determination unit 47.

The first side deviation amount comparison unit 45 includes a first side deviation amount (a first side deviation amount for the field A) in a predetermined A field (one field) and a B field (another field) adjacent to the A field. The first side deviation amount (the first side deviation amount for the field B) is compared.
For example, as shown in FIG. 7A, a change tendency of the first side deviation amount for the field A and a change tendency of the first side deviation amount for the field B are arranged, and the change tendency of the first side deviation amount is arranged. Compare if there is no difference.
When comparing the change tendency of the first side deviation amount for the field A and the change tendency of the first side deviation amount for the field B, the calculation start point (the position of the work position) when the calculation of the deviation amount is started. (Latitude or longitude).

The second side deviation amount comparison unit 46 determines a second side deviation amount (second field deviation amount for the field A) in a predetermined A field and a second side deviation amount (for the field B) for the B field (other fields). 2nd side deviation amount).
For example, as shown in FIG. 7B, the change tendency of the second side deviation amount for the field A and the change tendency of the second side deviation amount for the field B are arranged, and the change tendency of the second side deviation amount is arranged. Compare if there is no difference.

  The field determination unit 47 compares the first side shift amount (the first side shift amount for the field A, the first side shift amount for the field B) in the first side shift amount comparison unit 45 with the second comparison result. The farm work information corresponds to the field A based on the comparison result when the second side shift amount (the second side shift amount for the field A and the second side shift amount for the field B) in the side shift amount comparison unit 46 is compared. Or whether it corresponds to the field B.

  Specifically, as shown in FIG. 7, the field determination unit 47 does not substantially change the first side deviation amount for the farm A and the first side deviation amount for the farm B, and the second side deviation amount for the farm A. Corresponds to the work position when the change tendency of the second side shift amount for the farm B and the second side shift amount for the farm B is very large compared to the second side shift amount for the farm B. It is determined that the farm work information is not the field B on the side where the amount of deviation is large (the second side deviation amount side for the field B) but the field A.

As can be seen, by using the vertical side, the horizontal side, and the work position along which the combine 2 moves, it is easy to grasp which field the farm work information associated with the work position belongs to. can do.
That is, even when farm work information is collected while performing farm work in the field A or the field B by the combine 2, the information correspondence determination unit 42 performs the farm work information corresponding to the field A and the farm work information corresponding to the field B. And can be distinguished. That is, since the farm work information obtained by farming in a plurality of fields 3 can be accurately determined and divided, it is possible to prevent the farm work information in each field 3 from being confused. can do.

In the above-described embodiment, it is determined which farm work information is about the farm fields A and B that are adjacent to each other. However, which farm works information is about the farm fields A and C that are vertically adjacent to each other. It can also be determined whether it is.
Hereinafter, as a modification, the case of the vertically adjacent fields A and C will be described.
As shown in FIG. 8, when the combine 2 moves, the side extraction unit 40 extracts the lower horizontal side D2 of the field C as the second side (horizontal side) and the upper horizontal side of the field A Part U2 is extracted. In addition, the side extraction unit 40 extracts the left vertical side L1 of the field C and the left vertical side L1 of the field A as the first side (vertical side).

  The first side shift amount calculation unit 41a uses the position information of the left vertical side portion L1 of the farm field A to set the first side shift amount between the left vertical side portion L1 and the work position of the vertical section (first field A first for field A). (Referred to as side misalignment). In addition, the first side shift amount calculation unit 41a uses the position information of the left vertical side portion L1 of the field C to determine the first side shift amount (for the field C) between the left vertical side portion L1 and the work position of the vertical section. 1st side deviation amount).

  The second side deviation amount calculation unit 41b uses the position information of the upper horizontal side portion U2 of the farm field A to determine the second side deviation amount between the upper horizontal side portion U2 and the work position of the horizontal section (second field A second field A2). (Referred to as side misalignment). In addition, the second side deviation amount calculation unit 41b uses the position information of the lower horizontal side portion D2 of the field C to determine the second side deviation amount (for the field C) between the lower horizontal side portion D2 and the work position of the horizontal section. Second side deviation amount).

  For example, as illustrated in FIG. 9A, the first side deviation amount comparison unit 45 arranges the change tendency of the first side deviation amount for the field A and the change tendency of the first side deviation amount for the field C. Then, it is compared whether there is a difference in the change tendency of the first side deviation amount. For example, as illustrated in FIG. 9B, the second side deviation amount comparison unit 46 arranges the change tendency of the second side deviation amount for the field A and the change tendency of the second side deviation amount for the field C. Then, it is compared whether there is a difference in the change tendency of the second side deviation amount.

  As shown in FIG. 9, the farm field determination unit 47 has almost the same difference between the second side deviation amount for the farm field A and the second side deviation amount for the farm field C, and the first field deviation amount for the farm field A and the second field C pattern. When the change tendency with the one side deviation amount is different and the first side deviation amount for the field C is very large compared to the first side deviation amount for the field A, the farm work information corresponding to the work position is It is determined that the field A is not the field C on the side with the larger amount of deviation (the first side deviation amount side for the field C).

  As described above, according to the work machine information management system and the farm work information management device of the present invention, the work position when the combine 2 moves along the vertical side (first side) in the field, and the horizontal side The work position when moved along the part (second side) is stored in the information storage unit 30 and the above-described deviation amount calculation unit 41 and the information correspondence determination unit 42 are used to properly perform farm work. The field corresponding to the information can be specified.

In the above-described embodiment, the case where adjacent farm fields have the same shape has been described. However, as shown in FIG. 10, for example, even if the farm field A and the farm field B have a different shape from the farm field A, the farm work information A field corresponding to can be obtained. With reference to FIG. 10, the identification of a field in a field having a different shape will be described.
As shown in FIG. 10, when the combine 2 moves from P10 to P11, the side extraction unit 40 extracts the right vertical side R1 of the field A as the first side (vertical side), and the field B The left vertical side portion L1 is extracted. Further, the side extraction unit 40 extracts the upper horizontal side portion U2 of the field A as the second side portion (horizontal side portion), and the lower horizontal side portion of the field B on the side close to the extracted upper horizontal side portion U2. D2 is extracted.

Next, the first side shift amount calculation unit 41a uses the position information of the right vertical side portion R1 of the field A, and the first side shift amount for the field A between the right vertical side portion R1 and the work position of the vertical section. Ask for. In addition, the first side shift amount calculation unit 41a uses the position information of the left vertical side portion L1 of the field B to calculate the first side shift amount for the field B between the left vertical side portion L1 and the work position of the vertical section. Ask.
Further, the second side deviation amount calculation unit 41b uses the position information of the upper horizontal side portion U2 of the field A to calculate the second side deviation amount for the field A between the upper horizontal side portion U2 and the work position of the horizontal section. Ask. Further, the second side deviation amount calculation unit 41b uses the position information of the lower horizontal side part D2 of the field B to calculate the second side deviation amount for the field B between the lower horizontal side part D2 and the work position of the horizontal section. Ask.

  As described above, the first side shift amount calculation unit 41a and the second side shift amount calculation unit 41b perform various types of shift amounts (the first side shift amount for the field A, the first side shift amount for the field B, and the second for the field A. Even if the edge deviation amount and the second edge deviation amount for the field B) are obtained, the change tendency of the first edge deviation amount and the change tendency of the second edge deviation amount do not change. The field of agricultural machinery cannot be specified.

  However, when the combine 2 further proceeds from P11 and reaches P12, the side extraction unit 40 extracts the upper horizontal side U2 of the field A as the second side (horizontal side) and The lower horizontal side portion D2 is extracted. The side extraction unit 40 extracts the left vertical side L1 of the field A as the first side (vertical side), and the left vertical side L1 of the field B on the side close to the extracted left vertical side L1. Extract.

Next, the first side shift amount calculation unit 41a uses the position information of the left vertical side portion L1 of the field A, and the first side shift amount for the field A between the left vertical side portion L1 and the work position of the vertical section. Ask for. In addition, the first side shift amount calculation unit 41a uses the position information of the left vertical side portion L1 of the field B to calculate the first side shift amount for the field B between the left vertical side portion L1 and the work position of the vertical section. Ask.
Further, the second side deviation amount calculation unit 41b uses the position information of the upper horizontal side portion U2 of the field A to calculate the second side deviation amount for the field A between the upper horizontal side portion U2 and the work position of the horizontal section. Ask. Further, the second side deviation amount calculation unit 41b uses the position information of the lower horizontal side part D2 of the field B to calculate the second side deviation amount for the field B between the lower horizontal side part D2 and the work position of the horizontal section. Ask.

  In this case (when the combine further proceeds from P11 to P12), the field determination unit 47, as shown in FIG. 11, the field A second side shift amount and the field B second side shift amount are almost the same. The change tendency of the first side shift amount for the field A and the first side shift amount for the field B is different, and the first side shift amount for the field B is much smaller than the first side shift amount for the field A. Therefore, the farm work information corresponding to the work position is determined to be the field A, not the field C on the side with the larger amount of deviation (the first side deviation amount side for the field B).

In this way, even when adjacent fields are different, the field can be specified by calculating the shift amount for each side.
