The display units 65 and 66 are configured by a liquid crystal monitor, a liquid crystal panel, and the like, and can perform various displays. For example, the display units 65 and 66 display a plurality of agriculture maps in which a plurality of agriculture map data are visualized.

  The data selection unit 5 receives the selection of a plurality of arbitrary agricultural map data among the plurality of agricultural map data. The correlation operation unit 6 calculates the correlation of a plurality of arbitrary agricultural map data received by the data selection unit 5. That is, the data selection unit 5 and the correlation operation unit 6 of the agriculture support device 1 obtain correlations between at least two or more arbitrarily selected agriculture map data from among a plurality of agriculture map data. It is possible.

Next, the configurations of the display control unit 4, the data selection unit 5 and the correlation operation unit 6 will be described in detail.
For example, when the fixed terminal 64 logs in to the agricultural support apparatus 1, a menu screen for selecting a menu or the like is displayed on the display unit 65 of the fixed terminal 64 by the control of the display control unit 4 or the like. The following description will be made by taking the fixed terminal 64 as an example, but it is naturally applicable to the portable terminal 61.

When a button or the like is selected on the menu screen and a predetermined operation is performed, the fixed terminal 64 requests the agricultural support apparatus 1 for map support. As shown in FIG. 6, the display control unit 4 of the agricultural support device 1 displays the support screen M1 on the display unit 65 of the fixed terminal 64 in response to the request of the fixed terminal 64.
The support screen M1 includes a first map display unit 81 and a second map display unit 82. The first map display unit 81 displays an agriculture map F1 in which the agriculture map data stored in the map data storage unit 3A is visualized. For example, the display control unit 4 refers to the map data storage unit 3A, converts the agricultural map data stored in the map data storage unit 3A into the agricultural map F1, and displays the first converted map of the agricultural map F1. Display on the part 81. For example, the display control unit 4 refers to data such as numerical values and the like in the agricultural map data and the position (latitude, longitude). On the other hand, the display control unit 4 divides the field in the first map display unit 81 into a plurality of areas Qn (n = 1, 2, 3,... N), and each of the divided areas Qn in the agricultural map data The average value obtained by averaging a plurality of data Gn [i] (n: classification, Gn [i]: data, i: number of data) that enter the group is set as the representative value Dn (n = 1, 2, 3 ... n) Do. Alternatively, the display control unit 4 sets, as a representative value Dn, an integrated value obtained by integrating a plurality of data Gn [i] that enter each of the divided areas Qn in the agricultural map data. Alternatively, the display control unit 4 sets, as a representative value Dn, a numerical value around the area obtained by dividing the average value and the integrated value by the area of the area Qn.

  After obtaining the representative value Dn, the display control unit 4 assigns a plurality of groups (a plurality of ranks) according to the magnitude (value) of the representative value Dn, and changes colors etc. for each rank. Display the agriculture map F1. That is, the first map display unit 81 divides a field indicating a field etc. into a plurality of pieces, and displays a mesh type agricultural map in which data of agricultural map data is allocated to the area Qn. Further, in the embodiment described above, the visualization of the agricultural map F1 with a mesh type map is illustrated, but the visualized map of the agricultural map F1 is not limited to the above-described example.

  When a plurality of agricultural map data are stored in the map data storage unit 3A, the plurality of agricultural maps F1 are displayed vertically or horizontally in the first map display unit 81. When displaying the agricultural map F1 on the first map display unit 81, the display control unit 4 displays the map type of the agricultural map F1, the data type, and the agricultural map data that is the source of the agricultural map F1 around the agricultural map F1. Display map basic information such as acquisition date. In addition, basic information (map classification, data classification, acquisition date, etc.) of agriculture map F1 connects either of portable terminal 61 and fixed terminal 64 to agriculture support device 1, and inputs basic information. Basic information is associated with each map data (management information). The basic information may be automatically generated and associated with the management information, and may be stored in the map data storage unit 3A. There is no limitation on the input method and the association method.

Hereinafter, the thing of the agriculture map F1 displayed on the 1st map display part 81 for convenience of explanation is called 1st map F1.
The first map F1 displayed on the first map display unit 81 can be selected by the pointer 84. When the display unit 65 is a touch panel, the first map F1 displayed on the first map display unit 81 may be selected by the selection operation of the operator or the like.

  When an arbitrary first map F1 is selected by the pointer 84 or the selection operation in a state where the plurality of first maps F1 is displayed on the first map display unit 81, the data selection unit 5 selects The management information of an arbitrary first map F1 is held. When two or more of the plurality of first maps F1 are selected among the plurality of first maps F1 displayed on the first map display unit 81 and the completion button 85 displayed on the support screen M1 is selected, data selection is performed. The unit 5 outputs (notifies) the held plurality of management information to the correlation operation unit 6. Hereinafter, the first map F1 corresponding to the management information received by the data selection unit 5 among the plurality of first maps F1, that is, the first map F1 selected by the data selection unit 5 is referred to as “selection map” It is said. The agricultural map data corresponding to the selection map is called "selection data".

  The correlation operation unit 6 refers to the map data storage unit 3A and extracts a plurality of selection data from a plurality of agriculture map data. Here, assuming that the number of selection maps (the number of selection of selection data), that is, the number of management information held by the data selection unit 5 is “p”, the correlation operation unit 6 sets each of a plurality of selection data. A correlation coefficient of corresponding data Gn [i] p (n: division, i: number of data, Gn [i]: data, i: number of data, p = 1, 2 · · · selection number) is obtained. For example, when the number of selection maps is two and the growth map is selected for the first time (p = 1) and the seeding map is selected for the second time (p = 2) as the selection map, the correlation operation unit 6 The correlation coefficient between the growth data Gn [i] 1 that is the source of the growth map and the seeding data Gn [i] 2 that is the source of the seeding map is determined.

  Specifically, the correlation operation unit 6 uses the growth data Gn [i] 1 and the seeding data Gn [i] 2 to calculate the correlation coefficient Cn for each area Qn (n = 1, 2, 3....・ Ask for n). For example, when the number of data in area Q1 (n = 1) is 3 (i = 3), all data of growth data G1 [1] 1, G1 [2] 1, G1 [2] 1, and sowing data The correlation coefficient with all the data of G1 [1] 2, G1 [2] 2, G1 [2] 2 is set as the correlation coefficient C1 of the area Q1.

Then, the correlation operation unit 6 obtains the correlation coefficient Cn (n = 1, 2, 3... N) for each area Qn, and then obtains the obtained correlation coefficient Cn as the magnitude of the correlation coefficient Cn A correlation map F2 is created by assigning a plurality of groups (a plurality of ranks) according to the value).
The second map display unit 82 displays a correlation map F2 in which the correlation calculated by the correlation calculation unit 6 is visualized. That is, the second map display unit 82 displays the correlation map F2 in which the color or the like is changed for each rank of each area Qn allocated by the correlation operation unit 6. That is, in the second map display unit 82, the mesh type correlation map F2 in which the correlation coefficient Cn is assigned to the area Qn is displayed by dividing the field indicating the field etc. into a plurality. Although the embodiment described above exemplifies that the correlation map F2 is visualized as a mesh map, the correlation map F2 is not limited to the above-described example.

In addition, the second map display unit 82 displays, along with the correlation map F2, map basic information corresponding to a plurality of selection maps used to calculate the correlation coefficient Cn. For example, as described above, when the selection map is a growth map and a seeding map, map types, data types, acquisition dates and the like of the growth map and the seeding map are displayed.
As shown in FIG. 6, the support screen M1 may display a setting unit 83. The setting unit 83 is a part that performs various settings regarding the support screen M1. In the setting unit 83, for example, narrowing information of the agricultural map F1 displayed on the first map display unit 81 can be input. The narrowing-down information is an acquisition date, a range of acquisition dates, a type, and the like. When the narrowing-down information is input, only the agriculture map F1 corresponding to the narrowing-down information can be displayed on the first map display unit 81 among the plurality of agricultural maps F1.

  In the setting unit 83, the agricultural map F1 displayed by the first map display unit 81 and the second map display unit 82, and the length (longitudinal length and horizontal length) of one side of the area Qn in the correlation map F2 Can be set, or thresholds (ranges) of representative values Dn of a plurality of ranks (levels) can be set. The setting unit 83 can change the mesh length and the rank range of the area Qn.

FIG. 10 is a diagram showing a flow from acquisition of agricultural map data to display of a correlation map or the like.
The data acquisition unit 2 of the agriculture support device 1 acquires agriculture map data transmitted from a machine or the like regularly or irregularly (S1). After acquisition of the agricultural map data, the acquired agricultural map data is stored in the map data storage unit 3A together with the management information and the basic information (S2). When an agricultural worker connects to the agricultural support apparatus 1 using the portable terminal 61 or the fixed terminal 64 (S3), the support screen M1 is displayed on the display unit 66 of the portable terminal 61 or the display unit 65 of the fixed terminal 64 (S4) . A plurality of agricultural maps F1 are displayed on the support screen M1 (S5). When the selection of the plurality of arbitrary farming maps F1 is completed (S6), the correlation coefficient in the plurality of arbitrary farming maps F1 is calculated (S7), and the correlation map F2 is displayed (S8). As described above, by repeatedly performing S5 to S8, it is possible to find out a plurality of agricultural maps F1 that tend to have high correlation coefficients, or to grasp locations with high correlation in the correlation map F2.

  According to the above, the agricultural support system includes the data acquisition unit 2, the data selection unit 5 that receives the selection of a plurality of arbitrary agricultural map data among the plurality of agricultural map data acquired by the data acquisition unit 2, and the data selection unit A correlation operation unit 6 that calculates the correlation of a plurality of arbitrary agricultural map data received in 5 and a display unit that displays the correlation obtained by the correlation operation unit 6 (a display unit 66 of the mobile terminal 61 and a display unit of the fixed terminal 64 65) and. The agricultural support apparatus 1 further includes a data acquisition unit 2, a data selection unit 5, a correlation operation unit 6, and a display control unit 4.

  Therefore, for example, by having an agricultural worker such as an agricultural worker or a manager collect multiple agricultural map data and select any plural agricultural map data from among the collected multiple agricultural map data. In a plurality of selected agricultural map data, it is possible to grasp whether the correlation is high or low. In other words, when farmers have many data on yield, component data, growth data, soil component data, meteorological data, machine data, and operation data, they can grasp data with high correlation by selecting various combinations. It can be used for actual agriculture.

  The display unit 66 of the mobile terminal 61 and the display unit 65 of the fixed terminal 64 display a plurality of farming maps in which a plurality of farming map data are visualized, and the data selecting unit 5 displays a plurality of farming maps displayed on the displays 65 and 66. Accept the selected agricultural map from among the agricultural maps. According to this, it is possible to easily select the agricultural map to be used for obtaining the correlation while looking at the agricultural map of many agricultural map data.

Further, the correlation calculation unit 6 creates a correlation map F2 visualizing the correlation such as the correlation coefficient, and displays the correlation map F2 created by the correlation calculation unit 6 on the display units 65 and 66. According to this, the tendency of the correlation in the whole map can be grasped like the agriculture map used for asking for correlation.
The display units 65 and 66 cause the first map display unit 81 to display the farming map (selection map) F1 corresponding to the plurality of farming map data (selection data) used to obtain the correlation coefficient Cn, and the phase relationship A correlation map F2 indicated by a number Cn is displayed on the second map display unit 82. That is, since the display units 65 and 66 display the selection map F1 and the correlation coefficient Cn in association with each other, it is possible to visually grasp the relationship between the selection map F1 and the correlation coefficient Cn.

  Now, when the correlation calculation unit 6 creates the correlation map F2, the correlation calculation unit 6 creates new agriculture map data by setting the correlation coefficient Cn (correlation data) as agriculture map data. As shown in FIG. 5, specifically, when the correlation operation unit 6 creates the correlation map F2, the correlation operation unit 6 creates new management information for the correlation data, and creates new management information. , Correlation data (correlation coefficient Cn for each area Qn), and management information corresponding to a plurality of selection maps used to calculate the correlation of the correlation map F2 are stored in the map data storage unit 3A in association with each other. .

As described above, when the correlation calculation unit 6 creates correlation data, that is, the correlation map F2 based on the growth data and the seeding data, the correlation calculation unit 6 sets management information corresponding to the correlation data to “006-001. Set “-0000000002”, and associate the management information (001-004-0000000010) corresponding to the growth data with the management information (003-003-0000000001) corresponding to the seeding data as related information with respect to the management information. . Then, the correlation operation unit 6 creates new agricultural map data and correlation data by storing the correlation coefficient Cn, which is the correlation data, in association with the management information indicated by "006-001-0000000002". be able to.
In addition, as shown in FIG. 5, the correlation calculating part 6 respectively produces "correlation map", "correlation data", and "correlation map data," the map name corresponding to new agriculture map data, data classification, and an acquisition date. It is preferable to set “correlation map”, “correlation data”, and “the day on which the correlation map data was created” corresponding to “the day it was taken” as the basic information.

In the embodiment described above, management information corresponding to agricultural map data used to obtain correlation, for example, management information of growth data, management information of sowing data, is stored in the map data storage unit 3A as related information. However, instead of this, basic information of growth data and basic information of seeding data may be associated and stored in the map data storage unit 3A.
As described above, since the correlation data is added as new agricultural map data to the map data storage unit 3A, the first map display unit 81 can display the correlation map visualizing the correlation data as the agricultural map F1. The data selection unit 5 can select the correlation map.

Therefore, the newly created correlation data is added as a new agricultural map data and can be selected, so that the correlation data and the other data (crop data, soil data, weather data, machine data, work data) are also correlated Can be examined.
In the embodiment described above, the correlation operation unit 6 obtains the correlation coefficient Cn for each area Qn from the two or more selection maps F1, but the overall phase relationship of the data corresponding to the two or more selection maps F1 The number CT may be determined. Further, the entire correlation coefficient CT determined by the correlation calculation unit 6 may be stored in the correlation storage unit 3B together with the information of the selection map F1 used to obtain the correlation.

  For example, after selecting two or more selection maps F1 in the first map display unit 81, the correlation operation unit 6 uses all the data Gn [i] p corresponding to each of the plurality of selection data F1. The overall correlation coefficient CT is determined. For example, as the selection map F1, the growth map is selected at the first time (p = 1), the seeding map is selected at the second time (p = 2), and the correlation operation is performed when the number of data is 10 (i = 10) The part 6 obtains the overall correlation coefficient CT from all the data of the growth data Gn [1] 1 to Gn [10] 1 and the seeding data Gn [1] 2 to Gn [10] 2 (n: 1 ~ Max). The correlation storage unit 3B associates the management information (001-004-0000000010) corresponding to the growth data Gn [i] 1 with the management information (003-003-0000000001) corresponding to the seeding data Gn [i] 2. Then, at least the type (map type, data type) and the overall correlation coefficient CT determined by the correlation operation unit 6 are stored.

  As shown in FIG. 7A, in the above-described embodiment, the correlation storage unit 3B stores the management information together with the entire correlation coefficient CT, thereby obtaining the type (map type, data type) and the correlation operation unit 6 Although the correlation coefficient CT of the whole is associated and stored, as shown in FIG. 7B, by storing the basic information and the correlation coefficient CT of the whole in association, the type (map type, data type) and The entire correlation coefficient CT determined by the correlation operation unit 6 may be stored in association with one another. Alternatively, the correlation storage unit 3B may directly store the type (map type, data type) and the entire correlation coefficient CT.

The display units 65 and 66 display the entire correlation coefficient CT stored in the correlation storage unit 3B and the types (map type and data type) of a plurality of agricultural map data associated with the correlation coefficient CT. FIG. 8 shows the support screen M2. When a button or the like is selected on the menu screen and a predetermined operation is performed, a support screen M2 is displayed on the display unit 65 of the fixed terminal 64.
The support screen M2 includes a correlation display unit 86. As shown in FIG. 8, the correlation display unit 86 displays a list of the correlation coefficient CT stored in the correlation storage unit 3B and the type (map type, data type). For example, the display control unit 4 refers to the management information of the correlation storage unit 3B, determines basic information including the type from the management information, and displays a list of the calculated basic information and the correlation coefficient CT.

According to this, it is possible to grasp the correlation coefficient CT in at least two or more agriculture map data (selection data) and the type of agriculture map data (selection data) used to calculate the correlation coefficient CT. it can. For example, it can be grasped whether the relationship between the driving rotation map and the growth map is high or low.
Among the plurality of agricultural map data (selection data) used to obtain the correlation coefficient, the display units 65 and 66 are types of agriculture map data (selection data) for which the correlation coefficient CT is equal to or greater than a threshold value. The combination may be displayed. For example, as shown in FIG. 8, the correlation display unit 86 of the support screen M2 shows an input unit for inputting the upper limit value and the lower limit value of the correlation coefficient CT. When the upper limit value and lower limit value of the correlation coefficient CT are input, the display control unit 4 refers to the correlation storage unit 3B, and the management information corresponding to the correlation coefficient CT falling between the upper limit value and the lower limit value Search for. After the management information is retrieved, basic information including the type is determined from the management information, and the determined basic information, that is, the combination of the types of agricultural map data (selected data) and the phase relationship between the upper limit and the lower limit Display a list with several CTs. According to this, agricultural maps with high correlation can be grasped, and agricultural maps with low correlation can be grasped easily.

In the support screen M2 described above, the correlation coefficient CT of two or more selection data and the type of selection data are displayed, but instead, as shown in FIG. 9, two or more are displayed. A selection map F2 corresponding to the selection data and the correlation coefficient CT may be displayed.
