However, although the technique described in Patent Document 1 can select a suitable cultivated crop from the characteristics inherent to the seed, which seed is suitable for the user's cultivated land can be obtained by increasing the number of years of use. High reliability and high accuracy are required.
In addition, since the history of cultivated crops remains, it is possible to prevent a decrease in geopower due to crop rotation, but no specific method for crop rotation management is described.
Moreover, although the technique of the said patent document 2 can determine a cultivated crop from weather information, when determining the cultivated crop of the next season in consideration of the past cultivated crop, a continuous cropping failure does not arise. There are problems such as being unable to support.

  The object of the present invention is to manage the position and shape of the field, the position on the map, and the type of cultivated crop in units of a predetermined period (for example, in units of multiple years), and a field or continuous cropping failure in which proper rotation cultivation is performed occurs. It is an object of the present invention to provide a cultivated crop aged management method, apparatus, and program capable of visually displaying on a map a field that is likely to be cultivated and supporting the cultivation of a crop that can achieve an appropriate rotation.

In order to achieve the above object, the cultivated crop aging management method according to the present invention includes a shape of a field to be managed, position information, a cultivated crop type, a cultivated year, and a cultivated crop color and display color.

Compared with the case where a field is assigned a number or name and managed, information on the position and shape of the field is registered, so that complicated management is not required even when the field differs from the previous year due to a division or writing. become. Specifically, when the field is divided, it is only necessary to register the shape and position after the division on the map.
When overlaying and displaying the figure of the field, the overlay is performed so that the farm in the old year is in the lower layer. Can also be identified. Therefore, if there is a place where the same color is deeply painted, it will be immediately apparent that the same crop has been planted for multiple years.
Also, it is possible to display only the place where the crop in a certain year is cultivated by the display attribute information, so it is possible to cultivate the crop according to the rotation pattern or reverse cropping. It becomes possible to easily identify the farm field.

Hereinafter, the present invention will be specifically described with reference to the drawings showing an embodiment of the present invention.
FIG. 1 is a diagram showing an embodiment of a cultivated crop aging management system according to the present invention.
As shown in FIG. 1, the cultivated crop aging management system of the present embodiment includes a central processing unit 1 that performs input / output of data and database access, a display device 2 having a character and graphic screen, a keyboard, a mouse, and the like. The data input device 3, the map database 4 storing map data as background data of the graphic representing the field, and the field data composed of the position information of the graphic representing the field and information such as the type of cultivated crop are stored. It consists of a field database 5, a display style database 6 that defines display styles such as the fill color, fill pattern, and transmittance of a figure representing the field, and a crop master database 7 that defines the type and code of the cultivated crop.
The central processing unit 1 includes a data display process 11, a data input process 12, a display data creation process 13, a display style setting process 14, a field data registration process 15, a field data reference process 16, and a database access process 17. Each of these processes is specifically configured by a program stored in the memory of the central processing unit 1.
The data display process 11 is a process for displaying the display data created in the display data creation process 13 on the display device 2, and the data input process 12 is called from the field data registration process 15 or the field data reference process 16. This is a process of accepting data input in.
The database access process 17 is a process for referring to or updating data in the map database 4, the field database 5, and the display style database 6 as necessary.

The data stored in each database will be described.
FIG. 2 is a diagram showing the structure of the field data stored in the field database 5.
The farm field data has a figure ID 21 and shape information 22 for specifying a figure representing the farm field, and a style ID 23 possessed by the figure. The style ID 23 becomes a search key for the display style database 6.
In the figure ID 21, data of what number and figure of which layer is digitized and set.
The shape information 22 is composed of X and Y coordinate values of the vertices of a plurality of composing points constituting the graphic representing the farm field.
Further, the field data includes information such as a field number 24 for identifying the field, a cultivation year 25, and a cultivated crop 26. The codes corresponding to the cultivated crops are managed in the crop master database 7 for the cultivated crops, and it is desirable that the corresponding codes are set for the cultivated crops 26 in the field data.
The map data stored in the map database 4 also has a graphic ID, shape information, and style ID, similar to the field data.

FIG. 3 is a diagram showing the data structure of style data stored in the display style database 6.
Style data is prepared in advance for each type of graphic such as a river, a road, and a field of a specific crop, and each style data is assigned a unique style ID and stored in the style database 6.
The style data has a style ID 31 and an attribute value 33 for specifying a display style. The attribute value 33 is data of a line color 34, a line type 35, a line width 36, a fill color 37, a fill pattern 38, and a transmittance 39. Consists of.
The line color 34 designates the color of the line when displaying the display target graphic.
The line type 35 designates the type of line (solid line, broken line, etc.) when displaying the display target graphic.
The line width 36 designates the thickness of a line when displaying the display target graphic.
The fill color 37 is for designating the fill color in the graphic frame when displaying the display target graphic.
The fill pattern 38 is for designating a fill pattern (diagonal lines, shading, etc.) within a graphic frame when displaying a display target graphic.
The transmissivity 39 represents the transmissivity when the display target figures of a plurality of layers are overlaid and displayed in a color-coded manner, and the color of the figure displayed below is also checked at the same time when the field figure is overlaid. If desired, the transmittance 39 is set high.

Next, graphic data such as map data and field data will be described.
FIG. 4 shows the layer structure of the map database 4 and the field database 5.
The map data stored in the map database 4 has a layer structure with a plurality of layers as shown in FIG. 4, road figures are stored in the road layer 45, and river figures are stored in the river layer 46. When all the layers in the map database 4 are overlapped, the same image as the map 41 is obtained.
Similarly, in the field database 5, for example, the 2004 field pattern is stored in the 2004 field layer 47, the 2003 field pattern is stored in the 2003 field layer 48, and the 2002 field pattern is stored in the 2002 field layer 49. .
The display data creation processing 13 creates data to be displayed on the display device 2 by designating the coordinate value of the display range 50 on the map 41 and the display target layer from the input device 3.

A flowchart showing the processing procedure of the display data creation processing 13 is shown in FIG.
The display data creation process 13 first receives a display target from the data input device 3 in step S51.
The display target indicates what is displayed at which location, but the designation method may be various such as latitude / longitude designation, address designation, and figure type designation. To check whether an appropriate rotation is being performed in a field in a certain area, specify the area and the section of the cultivation year.
Next, the display range and display target layer on the map are determined from the display target specified in step S52.
Next, in step S53, the display range on the map is converted into a coordinate value represented by a coordinate system in the system.
Next, the farm field database 5 is accessed in step S54, and the farm figure included in the display range is extracted for each target layer in step S55.
Processing for setting a display style for the extracted graphic is step S56. The display style setting process in step S56 will be described later with reference to FIG.

As an example of graphic data display, FIG. 6 shows an example in which all fields in a certain area are displayed, and FIG. 7 shows an example in which fields at a place where a crop is designated are displayed.
FIG. 6 shows, as a color-coded display target, graphics of all layers of the map database 4 and all layers of the field database 5 in a certain display range.
The field graphic is displayed in different colors because different colors are defined in the display style database 6 for each type of cultivated crop.
Further, since all the field figures of the 2004 field layer 47, the 2003 field layer 48, and the 2002 field layer 49 are set as display targets, the fields for three years managed by the three layers are displayed in a superimposed manner. .
In FIG. 6, there is a portion (reference numeral 61) where the same color is displayed darkly, which indicates that there is a high possibility that the same crop is being continuously cropped.
FIG. 7 shows an example in which “potato” in 2002, “tensai” in 2003, and “soybean” in 2004 are conditioned.
In the display style database 6, it is assumed that the color of “potato” is beige, the color of “sugar beet” is purple, and the color of “soybean” is light blue. When "potato", "sugar beet", and "soybean" have an appropriate pattern for a three-year rotation, it is possible to easily recognize where the corresponding field is by color-coded display. A portion indicated by reference numeral 71 displayed in a mixed color of colors indicating each crop is a portion corresponding to an appropriate pattern in this case.
The display style setting process 14 required for color-coded display will be described.

FIG. 8 is a flowchart showing the processing procedure of the display style setting process 14.
When color-coded display is performed under certain conditions as shown in FIG. 7, fields other than the designated crop do not follow the display styles such as the fill color, fill pattern, and transmittance of the set style, and are not subject to color-coded display. . First of all for that judgment
In step S81, the display style creation process 14 determines whether the display target field graphic is a color-coded display target, that is, whether it is a specified crop field graphic. If it is not a color-coded display target, a style defined in advance for color-coding non-target is set in step S82, and the process ends.
For example, the line color 34 constituting the attribute value 33 is black, the line type 35 is a solid line, the line width 36 is 0, the fill color 37 and the fill pattern 38 are not included, and the transmittance 39 is 100%. This is a style in which an attribute that only displays the shape of the figure is set.
If it is a color-coded display target, the style ID 23 of the graphic data of the display target field is acquired from the field database 5 in step S83.
Next, an attribute value corresponding to the style ID acquired in step S84 is set, and the process ends.

Next, the field data registration process 15 will be described.
FIG. 9 is a diagram showing the operation of the field data registration process 15.
As shown in FIG. 9 (a), the field data is registered by displaying map data 91 as background data on the display device 2 and using the data input device 3 such as a mouse on the map data 91. Further, as shown in FIG. 9B, information on the field number 24, the cultivation year 25, the cultivation crop 26, and the farmer name 27 is inputted by the data input device 3 such as a keyboard.

FIG. 10 is a flowchart showing the processing procedure of the field data registration processing 15.
In FIG. 10, first, in step S101, the shape of the field is input on the map data as the background. Specifically, a plurality of composing points constituting the shape of the field to be registered are sequentially designated and input by the input device 3 on the map displayed on the display device 2.
Next, in step S <b> 102, it is determined whether or not a specific operation or command of the input device 3 indicates that the input operation of the constituent points constituting one field has been completed. When the input completion is instructed, in step S103, composition point data constituting one input field graphic is acquired.
Next, in step S104, the acquired constituent points are converted into coordinate values represented by a coordinate system in the system, and in the next step S105, the number of constituent points is checked. An error occurs because cannot be created.
If there are three or more composing points, it is also checked in step S106 whether the composing points are not self-intersecting.
If not self-intersecting, shape information 22 (number of vertices, X coordinate value of vertex 1 to Y coordinate value of vertex n) shown in the data structure of the field database 5 in FIG. 2 is created in step S107.
Next, in step S108, the information of the style ID 23, the field number 24, the cultivation year 25, the cultivation crop 26, and the farmer name 27 in FIG. 2 is received from the data input device 3, and in the next step S109, the field database in FIG. 5 is created, and the field data is registered in the field database 5 using the database access process 17 in the next step S110.
In this case, the figure ID 21 is automatically generated and registered for each figure of one field.

Next, the reference process for the field data will be described.
FIG. 11 is a diagram showing operations of the field data reference process.
As shown in FIG. 11, when an arbitrary position of the field graphic displayed in a superimposed manner is pointed by the data input device 3 such as a mouse, the cultivated crop of the field graphic existing at that position can be acquired. Pointing to the place of the code 111 where the purple color is dark, the type of crop cultivated in the past is displayed in text. In the example of FIG. 11, it is displayed that “sugar beet” has been planted over the past three years, and this display indicates that another crop must be cultivated so that a proper crop rotation can be achieved in the next season. . In other words, it is understood that there is a risk of continuous cropping failure when “Tensai” is grown in the next season.
In addition, when the place indicated by reference numeral 112 is pointed, the type of crop cultivated in the past is displayed in a letter. In the example of FIG. 11, it can be seen that a rotation of potato → sugar beet → wheat is performed, and it is understood from the rotation pattern that the cultivated crop suitable for the next season is “potato”.

FIG. 12 is a flowchart showing the processing procedure of the field data reference processing 16.
In step S121, the field data reference processing 16 performs a point position on the map displayed on the display device 2 when a place where the field figure superimposed and displayed as shown in FIG. The point position data is acquired in step S122.
Next, the acquired coordinates of the point position are converted into coordinate values represented by a coordinate system in the system in step S123.
Next, in step S124, the field database 5 is accessed using the database access process 17, and in step S125, field data in which the coordinates of the component points including the coordinate values are present is acquired in units of years.

As described above, the types of cultivated crops cultivated over a plurality of years in the field existing in the designated area can be displayed in different colors. In addition, if the same type of crop has been cultivated continuously over multiple years, the color of the field figures in each year's hierarchy is superimposed, resulting in a darker display color density and continued cropping. Displayed visually.
When continuous cropping is not continued, since different colors are superimposed, the display color of a specific crop does not become dark and it can be seen that proper crop rotation is being performed.

The map data to be displayed on the display device 2 may be acquired via a network.
In addition, the example of specifying the area with the map displayed is explained, but first, specify the address of the field, the field number, the farmer name, the target year, and call the corresponding field data. The map data in a range including the position coordinates in the field data can be acquired and the map can be displayed, and the type of cultivated crop in the target year in the corresponding field can be displayed on the map.
Moreover, the display data creation process incorporated in the central processing unit 1 can be provided as a program that can be executed by a general-purpose personal computer.
