(Hardware configuration)
FIG. 1 shows a block diagram of an agricultural information processing device 100. As shown in FIG. The agricultural information processing apparatus 100 includes an identification information reception unit 101, a field data storage unit 102, an initial screen selection unit 103, a work plan storage unit 104, a work content storage unit 105, a progress determination unit 106, a display control unit 107, and a display device. 108.

The agricultural information processing device 100 is implemented using a commercially available PC (personal computer). Application software for realizing each functional unit shown in FIG. 1 is installed in the PC. As the display device 108, a display device such as a liquid crystal display device included in the PC or a display device externally attached to the PC is used.

Functional units other than the display device 108 can also be grasped as a processor that executes the relevant functions, an electronic circuit that executes the relevant functions, and a software program that executes the relevant functions.

Various control computers (for example, computers for automatic steering control and automatic operation control of tractors), applications for realizing the functions of the functional units shown in FIG. 1 on a server that can be connected via a communication line It is also possible to install software and operate the computer as the agricultural information processing device 100 . A laptop computer or the like can be used as the PC to be used. Moreover, a configuration is also possible in which a user's PC is used as an interface and a server connectable to the PC via a line is operated as the agricultural information processing apparatus 100 .

In this case, various calculations (processing) are performed on the server side, and the PC is used as an operation terminal. Also, a form in which a smartphone is used as an operation terminal is also possible.

The agricultural information processing device 100 can be configured with various processors. For example, the agricultural information processing apparatus 100 can also be configured by electronic circuits such as PLD (Programmable Logic Device) represented by ASIC (Application Specific Integrated Circuit) and FPGA (Field Programmable Gate Array). It is also possible to configure part of the functions with dedicated hardware and configure the other part with a general-purpose microcomputer.

The identification information reception unit 101 receives identification information of a user who operates the agricultural information processing device 100 . The identification information is entered using techniques such as passwords, IC cards, magnetic cards, barcodes, and biometric authentication.

In this example, as shown in FIG. 2, three levels (three types) of users are set: a parent user (grower), a child user, and an agricultural instructor. A parent user is an owner (or a representative or person in charge of an agricultural corporation) who owns a plurality of fields. A farm field is a farmland that is partitioned and partitioned by banks, fences, or the like. In addition, even if the farmland is not visually partitioned, it is possible to grasp the farmland partitioned on the data of the electronic map as the agricultural field.

A child user is hired by a parent user and takes charge of farm work in one or a plurality of fields owned by the parent user. Agricultural instructors are technical consultants who have a consulting contract with parent users, and give various advice to parent users and child users. Agricultural instructors may enter into a consulting contract with other parent users other than the parent user concerned.

Parent users have access to data for all fields they own. However, it is not possible to access the data of fields owned by other parent users. Child users can only access the data of fields they are in charge of.

Agricultural instructors can access the agricultural information of parent users with whom they have a consulting contract. For example, assume that an agricultural instructor has a consulting contract with parent user A and parent user B. In this case, parent user A cannot access the data of the field owned by parent user B. In addition, parent user B cannot access the data of the farm field owned by parent user A. Agricultural instructors can access parent user A's and parent user B's agricultural information.

It should be noted that the content of user access rights for each layer described above is an example of settings, and the settings can be changed. It is also possible to set two types (two layers) or four types (four layers) or more as the types of users.

Field data includes field position (longitude, latitude, elevation), field type (type of paddy field, field, etc.), information on crops to be grown, past growth history, person in charge of work, soil map, fertilization map , Training map included. The field position data includes not only data on one point in the field but also data on the positions of various parts of the field.

The field data includes data of an aerial image of the field photographed from above. In the aerial photographed image of the field, the position of each point in the photographed image (the position in the absolute coordinate system, such as latitude, longitude, and altitude) is specified by a technique used in aerial photogrammetry. Here, the relationship between the soil map, the fertilization map, the cultivation map, and the aerial photograph image is specified via position information. Therefore, a soil map, a fertilization map, or a growing map can be synthesized and displayed on the display of an aerial photograph image.

The soil map is a map that indicates the condition of the soil of the field. A soil map specifies the relationship between a position (latitude and longitude) in an absolute coordinate system and the state of the soil (eg, nutrient content) at that position. For example, the soil map may be a map showing the distribution of the content of various nutrients, the distribution of the water content, and the distribution of the pH. Soil maps are created based on analysis of aerial photographs and measurements by optical sensors.

The fertilization map is a map that determines the amount of fertilizer to be applied to the field. The fertilization map specifies the relationship between the position (latitude and longitude) in the absolute coordinate system and the amount of fertilizer applied at that position. For example, a fertilization map is obtained by dividing a field into a matrix and determining the fertilization amount for each unit division. Normally, a fertilization map is created based on the soil map.

The growing map is a map showing the distribution of the growing state of crops in the field. In the growing map, the relationship between the position (latitude and longitude) in the absolute coordinate system and the growing state (for example, stem length) of the crop at that position is specified. Growth conditions include stem length, leaf color, fruit size, and the like. The growing state of crops is created based on the optical analysis of captured images and the measurement results of various sensors. The soil map, fertilization map, and cultivation map are described, for example, in Japanese Patent Application No. 2019-031202.

Field data is stored in the field data storage unit 102 . A storage device (semiconductor memory) of a PC or a hard disk device is used as the field data storage unit 102 . As the field data storage unit 102, a server connected to the Internet line or an external storage medium can be used.

The initial screen selection unit 103 selects an initial screen corresponding to the user's identification information received by the identification information reception unit 101 . Here, the initial screen is a screen first displayed on the display device 108 after the application software for operating the agricultural information processing apparatus 100 is activated on the PC to be used and the user is authenticated.

In this embodiment, the information that can be accessed differs depending on the user's hierarchy, so the initial screen is selected according to the difference in information.

FIG. 3 shows an example of the initial screen. The initial screen shown in FIG. 3 is an initial screen displayed when a parent user or an agricultural instructor logs in. Login is performed by inputting identification information (authentication data). In this case, the user (parent user or child user) whose farm work progress is delayed and the farm field whose work is delayed are highlighted in the aerial photograph image.

Here, the aerial photograph image of the field is associated with position data. Also, the relationship between the aerial photograph image of the field, the soil map, the fertilization map, and the cultivation map is acquired in advance. Therefore, a mode is possible in which the user designates a specific portion captured in the aerial photograph image, and the soil map, fertilization map, or cultivation map of that portion is displayed. This is the same for FIGS. 4 to 6 as well.

FIG. 4 is an initial screen displayed when an agricultural instructor logs in. FIG. In this example, only the parent user can be checked with the agricultural instructor's account. Of course, it is also possible to set so that even child users can be checked.

FIG. 5 shows an initial screen displayed when the parent user logs in. FIG. In this case, only child users of the parent user can be confirmed (the agricultural information of child users of other parent users cannot be accessed).

FIG. 6 shows an initial screen displayed when a child user logs in. FIG. In this case, what can be confirmed is limited to the data of the field that the child user is in charge of.

The work plan storage unit 104 stores a work plan for each field. The work plan is prepared prior to farm work, and is a process chart for disinfection, fertilization, plowing, sowing seeds (planting seedlings), various measurements, spraying chemicals, and other work related to farming. The work plan describes the schedule (which may be approximate) for each task.

The work content storage unit 105 is a record of the content of work performed in each field. For example, the work content recording unit 105 records the content that XX work is performed on XX day. Although it is assumed that the child user in charge of the work inputs the record of the work content, it may be done by a person other than the child user.

The progress determination unit 106 compares the work plan with the contents of the work content storage unit and determines the progress of the work. For example, if a task scheduled to be performed between May 10th and May 20th in the work plan has not been performed by May 25th, it is determined that the task is delayed.

The display control unit 107 controls the display device 108 to display screens as shown in FIGS. 3 to 6 by using the GUI function unit of the PC to be used. For example, the display control unit 107 creates a composite image by combining an aerial photograph image with a soil map, a fertilization map, or a cultivation map. Further, when it is determined that the work will be delayed, the display control unit 107 controls the display to notify the fact.

(Example of processing)
When the PC constituting the agricultural information processing apparatus 100 is activated, the process of the flowchart shown in FIG. 7 is executed. This processing is recorded in an appropriate storage area and executed in the PC.

When the application software realizing the agricultural information processing apparatus 100 is activated, the processing shown in FIG. 7 is executed. First, it is determined whether user identification information has been received (step S101). When the identification information of the user is received, the hierarchy of the received identification information is obtained (step S102). Next, an initial screen is selected according to the obtained hierarchy (step S103).

Next, progress is determined (step S104). The progress is determined by comparing the work plan and the record of work details. After the progress is determined, the progress is notified (step S105). FIGS. 3 to 6 show an example of a case where the progress is notified on the screen.

(feature)
(1) Agricultural Instructor When logging in as an agricultural instructor, a list of users who are subject to guidance is displayed on the left side of the screen, and the cards of users whose progress is behind schedule are colored. On the right side of the screen, the fields owned by all users and the data in them are displayed. This display is based on an aerial photograph image, and it is possible to visually grasp the position and condition of the field. Moreover, the data to be displayed are a growth map, a fertilization map, and a color representation of the degree of work progress, which can be selected.

A warning color and details of the delay are automatically displayed in the field of the user whose progress is delayed. Only the parent user can be confirmed with the agricultural instructor's account, and the progress of the child user cannot be confirmed. If it does in this way, an agricultural instructor will manage progress of the user who is an instruction object. Also, it is easy to compare progress between users.

(2) Parent User If you log in as a parent user, you will see a list of yourself and your child users on the left side of the screen, and the cards of users whose progress is behind schedule will be colored. There is always a one-to-one relationship between the user and the field. On the right side of the screen, an aerial photograph image of the field owned by the user and various data are displayed. The data is a growth map, a fertilization map, and the progress of work expressed in colors, and can be selected. A warning color and delay details are automatically displayed on the user's farm where the progress is delayed. In this way, it is possible to manage progress among users including oneself.

(3) Child User When logged in as a child user, a list of fields in charge is displayed on the left side of the screen, and the cards of fields whose progress is behind schedule are colored. On the right side of the screen, the field you are in charge of and the data in it are displayed. The data is a growth map, a fertilization map, and the progress of work expressed in colors, and can be selected. A warning color and delay details are automatically displayed for farms that are slow to progress.

(4) Overall By registering the yearly schedule in advance by the parent user or agricultural instructor, the user's progress can be displayed. The user can freely switch the order of the user list and field list. Modes of switching include the alphabetical order of names, the order of progress, and the order of items close to the current location using the GPS function (field list only). This function can be said to be user-friendly because it gives priority to the information that the user wants to see.
