Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are examples that embody the present invention, and are not intended to limit the technical scope of the present invention.

(Embodiment 1)
[1] Overall Configuration As shown in FIG. 1, the work map creation system 10 according to the present embodiment includes a management server 2 and a user terminal 3. The work map creation system 10 creates a work map M1 (see FIG. 3) used for work in the field F1 (see FIG. 2). As an example in the present embodiment, the work map M1 is a "fertilizer application map" used for fertilizer spraying work (that is, fertilizer application work) in the field F1. Such a work map M1 is a kind of work support information D1 (see FIG. 2) used for spraying work (including fertilization work) in the field F1. Therefore, the work map creation system 10 according to the present embodiment is an example of the work support information creation system that creates the work support information D1.

The work map M1 (work support information D1) created by the work map creation system 10 is output from the work map creation system 10 in a format that can be input to the work machine 4, and is used by the work machine 4, for example. The "working machine" as used in the present disclosure means various working machines that move in the field F1, and as an example, a work vehicle such as a rice transplanter, a tractor, a sprayer, a sprayer, a seeder, a transplanter, and a combine. Is. That is, the work machine includes the work vehicle. The work machine 4 is not limited to a “vehicle” such as a rice transplanter and a tractor, and may be, for example, a work projectile such as a drone or a multicopter for fertilization or pesticide spraying. Further, the work machine 4 is not limited to the agricultural machine (agricultural machine), and may be, for example, a construction machine (construction machine) or the like. In the present embodiment, unless otherwise specified, the work machine 4 is a passenger-type rice transplanter, and at least the spraying work of "fertilizer" as a spraying material, that is, the fertilizing work can be performed as a work. I will explain it by citing it.

Further, the "field" referred to in the present disclosure is a work target area where various operations such as fertilization, pesticide spraying, sowing, planting (rice planting) or harvesting are performed while the work machine 4 is moving, and the agricultural products are used. Includes rice fields, fields, orchards and pastures to grow. In this case, the crop grown in the field F1 is an agricultural product. Further, when the plants are grown in the plantation field, the plantation field becomes the field F1, and when the trees to be wood are grown in the forest as in the forestry, the forest becomes the field F1. In this case, the crops cultivated in the field F1 are plants, trees and the like. Since such a field F1 is a specific place in a real space (existing space), the position, shape, size, etc. are represented by, for example, an address on a map, latitude, longitude, or the like. In the present embodiment, the case where the work target area for performing various tasks while the work machine 4 moves in the real space is the field F1 will be described, but the work target area may be other than the field F1. good. For example, if the work machine 4 is a construction machine, the work site where the construction machine works is the work target area. In the present embodiment, unless otherwise specified, the case where the field F1 is an outdoor rice field will be described as an example.

Further, it is not essential that the work map M1 (work support information D1) created by the work map creation system 10 is used by the work machine 4. That is, the work supported by the work map M1 created by the work map creation system 10 may be any work related to the cultivation of crops in the field F1, and is not limited to the work performed by the work machine 4. For example, the work map M1 created by the work map creation system 10 may be used for the work performed by the person at a plurality of positions in the field F1, such as the work performed by the person while moving the field F1. As an example of this kind of work, there is a spraying work (including fertilizer application work) in which a person sprays fertilizer or a chemical (pesticide). Such work such as spraying work may be performed by the work machine 4, but it may also be performed by a person. Then, even when a person performs work such as spraying work, for example, the spraying amount of the sprayed material (fertilizer, chemicals, etc.) can be adjusted with reference to the work map M1. However, in the present embodiment, unless otherwise specified, a case where the work map M1 (work support information D1) used in the work machine 4 is created by the work map creation system 10 will be described.

In the present embodiment, the work machine 4 using the work map M1 (work support information D1) created by the work map creation system 10 is not included in the components of the work map creation system 10, but the work machine 4 may be included in the components of the work map creation system 10. Further, in the present embodiment, the user terminal 3 is included in the component of the work map creation system 10, but it is not essential that the user terminal 3 is included in the component of the work map creation system 10. That is, the work map creation system 10 may or may not include at least one of the work machine 4 and the user terminal 3 as a component. When the work map creation system 10 does not include both the work machine 4 and the user terminal 3 in the components, the work map creation system 10 includes only the management server 2 in the components.

The management server 2 and the user terminal 3 can communicate with each other. "Communicable" as used in the present disclosure means direct communication or via a communication network (network) N1 or a repeater by an appropriate communication method of wired communication or wireless communication (communication using radio waves or light as a medium). It means that information can be exchanged indirectly. The management server 2 and the user terminal 3 can communicate with each other via, for example, the Internet, LAN (Local Area Network), WAN (Wide Area Network), public telephone line, mobile phone line network, packet line network, wireless LAN, or the like. be. The communication means between the management server 2 and the user terminal 3 is not limited to the above example, and is realized by an appropriate communication means. Further, it is not an essential configuration in the work map creation system 10 that the management server 2 and the user terminal 3 can communicate with each other. For example, even if there is no communication function between the management server 2 and the user terminal 3, the management server 2 records the information on a computer-readable non-temporary recording medium, and the user terminal 3 records the information from the recording medium. By reading, it is possible to exchange information offline.

On the other hand, the exchange of information between the user terminal 3 and the work machine 4 is performed offline, not communication, as an example in the present embodiment. That is, by recording information on a non-temporary recording medium that can be read by a computer on the user terminal 3 and reading the information from the recording medium on the work machine 4, information can be exchanged offline. Specifically, the data output unit 36 of the user terminal 3 described later writes the work support information D1 (including the work map M1) to the portable recording medium 5 (see FIG. 2) connected to the user terminal 3. The work machine 4 reads the work support information D1 from the recording medium 5. Thereby, the work map M1 (work support information D1) created by the work map creation system 10 can be input to the work machine 4. Further, for example, the user terminal 3 and the work machine 4 may be able to communicate with each other, and in this case, information may be exchanged between the user terminal 3 and the work machine 4 by communication.

In the present embodiment, the management server 2 has a core function of the work map creation system 10. That is, the management server 2 has a function of creating (generating) a work map M1 (work support information D1). The user terminal 3 is a communication terminal used by the user. For example, in order to access the website of the work support service provided by the management server 2 (for example, "work support site") on the user terminal 3 and create the work map M1 (work support information D1). It is possible to display the screen (web page) of. The number of user terminals 3 may be one or a plurality.

The work machine 4 that uses the work map M1 (work support information D1) created by the work map creation system 10 may be one or a plurality of machines. When there are a plurality of work machines 4, the plurality of work machines 4 jointly execute a spraying operation for spraying a sprayed material (fertilizer, chemicals, etc.) in, for example, one or a plurality of fields F1. Further, the plurality of work machines 4 using the work map M1 (work support information D1) may include different types of work machines 4, such as rice transplanters, tractors, and drones.

[2] Working Machine Next, the configuration of the working machine 4 (passenger type rice transplanter in this embodiment) will be described with reference to FIG.

The work machine 4 has a traveling block 41 that moves in the field F1 and an attachment block 42 that executes the work. The traveling block 41 has a power source (engine, motor, etc.), a transmission, a steering device, an operation device, a control device, an actuator, and the like. The traveling block 41 is configured to be able to travel in the field F1 by utilizing the power generated by the power source. The attachment block 42 is connected to the traveling block 41 (including mounting and mounting), and performs operations such as fertilizer spraying (fertilizer application) and chemical spraying (pesticide spraying). The attachment block 42 operates by utilizing, for example, the power generated by the power source of the traveling block 41.

In the present embodiment, as an example, the work machine 4 operates (autonomously travels) by automatic operation. Specifically, the work machine 4 is a position detection unit that detects the position (latitude and mildness) of the work machine 4 by using a satellite positioning system such as GNSS (Global Navigation Satellite System), and the posture of the work machine 4. The control device includes a posture detection unit and the like for detecting. As an example, the position detection unit detects a position with relatively high accuracy, as in RKT (Real Time Kinematic) positioning.

Here, the control device of the working machine 4 includes a computer system having one or more processors and one or more storage memories such as a non-volatile memory and a RAM (Random Access Memory). The control device is configured so that the portable recording medium 5 can be connected, and by connecting the recording medium 5, the work support information D1 (including the work map M1) can be read from the recording medium 5. The control device automatically controls the traveling block 41 and the attachment block 42 based on the current position and posture of the work machine 4 and the work map M1 of the work support information D1. As a result, the work machine 4 can autonomously perform the work while traveling in the field F1 along the travel path according to the work support information D1.

In particular, in the present embodiment, the work machine 4 executes at least a fertilizer spraying operation (fertilizer application operation). Therefore, the work machine 4 performs the spraying work according to the spraying amount (fertilizer) specified in the work map M1 while changing the spraying amount for each position of the field F1. Fertilizer application work) can be carried out. That is, if the spraying amount of each position of the field F1 is instructed in the work map M1, the sprayed material (fertilizer) can be sprayed in the distribution according to this instruction by the work machine 4. As a result, even within the same field F1, the spraying work while finely adjusting the spraying amount for each position can be automatically realized.

However, the work machine 4 is not limited to the configuration operated by automatic operation, and may be operated by a person (operator) operation (including remote control). In this case, the person operates the work machine 4 according to the work map M1 while looking at the work map M1 displayed on the display of the work machine 4, the user terminal 3, or the like, for example.

[3] Work Map Next, the work map M1 (work support information D1) created by the work map creation system 10 will be described with reference to FIG.

As described above, in the present embodiment, the work map M1 which is a product of the work map creation system 10 is a kind of work support information D1 used for the spraying work. Specifically, the work support information D1 includes the work map M1. The work map M1 has a plurality of compartments K (see FIG. 3) and corresponds to the field F1. A work index indicating the amount of sprayed material is set for each of the plurality of compartments K. The work map M1 used for the spraying work as described above, wherein the sprayed amount of the sprayed material is the work index of each section K, is also referred to as a “spraying map”. In particular, as in the present embodiment, the work map M1 which is used for the fertilizer application work in which the fertilizer is sprayed as a spray material in the spraying work and the fertilizer application amount (fertilizer application amount) is the work index of each section K is set as "fertilizer application". Also called "map".

In short, the work map M1 as the work support information D1 includes a spray map in which the spray amount of the sprayed material at each position corresponding to the plurality of sections K in the field F1 is used as the work index. Furthermore, the work map M1 includes a fertilizer application amount having the amount of fertilizer applied at each position corresponding to the plurality of sections K in the field F1, that is, the amount of fertilizer applied as a sprayed product as a work index. Here, as an example in the present embodiment, the spraying amount as a work index will be described as the amount of sprayed material (fertilizer) sprayed per unit area. That is, the amount of spray as a work index is not the total amount of spray (fertilizer) sprayed in each section K, but the average amount (average value) of the spray in each section K. As an example, if the unit area is "10a" and the amount of the sprayed material (fertilizer) is expressed by weight (kg), the unit of the sprayed amount as the work index is "kg / 10a". However, the work index may be a representative value in each section K and is not limited to an average value such as the amount of spraying per unit area, but the total value, median value, mode value, maximum value or minimum value in each section K. It may be a representative value such as a value. As an example, the spraying amount as the work index may be the total amount (total value) of the sprayed matter (fertilizer) sprayed on each section K.

More specifically, the plurality of sections K in the work map M1 are set not for the field F1 itself but for the work area A1 (see FIG. 3) corresponding to the field F1. The work map M1 is data in which a work index such as a spraying amount (fertilization amount) is assigned to each of the plurality of sections K set in the work area A1 in this way. The "work area" referred to in the present disclosure is a two-dimensional area set in the virtual space corresponding to the field F1 and is used for creating the work map M1. That is, the area set on the virtual space for creating the work map M1 corresponding to the field F1 existing in the real space is the work area A1.

Therefore, the "section" referred to in the present disclosure means an individual area after division in the virtual space when the work area A1 on the virtual space is divided into a plurality of areas. Each of the plurality of compartments K is a region having a predetermined shape such as a square shape. The work map creation system 10 according to the present embodiment sets the work area A1 on the virtual space, sets a plurality of sections K in the work area A1, and further sets a work index (fertilizer application amount) in the plurality of sections K. By assigning (corresponding) to, the work map M1 is created.

As an example, the work map M1 is created by dividing the entire work area A1 into a plurality of sections K in a mesh shape and assigning a work index to each section K, as shown in FIG. FIG. 3 schematically shows a state in which the work area A1 is divided into a plurality of sections K. For example, each section K is a square area of 5 m × 5 m in terms of actual size in the corresponding field F1. However, the shape and size of each section K are not particularly limited. On the left side of FIG. 3, the coordinate information (section number) of the X coordinate (X axis) and the Y coordinate (Y axis) is attached as the identification information of each section K.

More specifically, the work map M1 is map data including information such as the corresponding "section number" and "work index" for each section K of the work area A1. The section number is the identification information of the section K. As a result, the work index (spraying amount) is registered for each section K. By displaying such a work map M1 on the user terminal 3, for example, the work map M1 is visualized as shown on the right side of FIG. 3 as an example. In the example of FIG. 3, the work map M1 adopts, for example, a multi-gradation gray shade (gray scale) or a mode in which each color is associated with the work index. In this example, for each section K, the lighter the color, the smaller the amount of spraying, and the darker the color, the larger the amount of spraying. Further, the larger the number of sections K (number of divisions) in the work area A1, the higher the definition of the work map M1. The "numerical value" of the work index may or may not be displayed in each section K of the work map M1.

The work map M1 as described above represents the distribution of the work index in the work area A1 and thus represents the distribution of the spray amount (fertilizer application amount) in the entire field F1 corresponding to the work area A1. become. That is, by executing the spraying work according to the work map M1, the spraying amount of the sprayed material in the field F1 can be adjusted for each position corresponding to each section K. This makes it possible to reflect the distribution of the work index in the work map M1 in the distribution of the sprayed amount (fertilizer applied amount) of the sprayed material (fertilizer) with respect to the actual field F1.

However, the work in which the work map M1 is used is not limited to the spraying work (including the fertilization work). Therefore, when generalized, it can be said that the work map M1 has a plurality of sections K for which a work index is set, and is data corresponding to the field F1. Here, the work index is some index (value) related to the work at each position corresponding to each section K in the field F1, and is, for example, the amount of resources used for the work, the time, the man-hours, and various types of the work machine 4. Set values, etc. In the present embodiment, since the work shown in the work map M1 is the spraying work of the sprayed material, the sprayed amount at each position corresponding to each section K in the field, more specifically, the fertilizer application amount, that is, the sprayed material. The amount of fertilizer sprayed is the "work index".

[4] Management Server Next, the configuration of the management server 2 will be described in detail with reference to FIG. The management server 2 is a server including an information processing unit 1, a data storage unit 21, an operation reception unit 22, a (server side) communication unit 23, and the like. The management server 2 is not limited to one computer, and may be a computer system in which a plurality of computers operate in cooperation with each other. Further, various processes executed by the management server 2 may be distributed and executed by a plurality of processors.

The data storage unit 21 includes a non-volatile storage device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) that stores various types of information. The data storage unit 21 stores (stores) a control program such as a work map generation program for causing the information processing unit 1 to execute the work map M1 generation method described later. The work map generation program is, for example, recorded and provided on a computer-readable non-temporary recording medium, read from the non-temporary recording medium by the reading device of the management server 2, and stored in the data storage unit 21. The work map generation program may be provided (downloaded) to the management server 2 from a server other than the management server 2 via a telecommunication line (communication network N1) and stored in the data storage unit 21.

Further, the data storage unit 21 includes a work support information storage unit 211 and an acquisition information storage unit 212. The work support information storage unit 211 stores the work support information D1 including the work map M1. That is, the work support information D1 (including the work map M1) created (generated) by the work map creation system 10 is stored in the work support information storage unit 211. The acquisition information storage unit 212 stores various information acquired by the information acquisition unit 13, which will be described later.

The operation reception unit 22 receives the user's operation. Specifically, since the management server 2 can communicate with the user terminal 3, the operation reception unit 22 transmits an operation signal corresponding to the user's operation to the operation unit 34 of the user terminal 3, which will be described later, from the user terminal 3. By doing so, the user's operation is indirectly accepted. That is, when the user operates the user terminal 3, the user terminal 3 generates an operation signal corresponding to the user's operation, and the operation signal is transmitted from the user terminal 3 to the management server 2. Therefore, the operation receiving unit 22 can receive the user's operation by the operation signal received from the user terminal 3 by the management server 2. Further, the operation receiving unit 22 is not limited to the user's operation on the operation unit 34 of the user terminal 3, and may accept the user's operation (administrator of the management server 2 or the like) on the operation unit other than the user terminal 3. In this case, the operation unit is realized by, for example, a touch panel, a mouse, a keyboard, or the like provided in the management server 2 or attached to the management server 2.

The communication unit 23 is a communication interface having a communication function with an external device such as a user terminal 3. Specifically, the communication unit 23 connects the management server 2 to the communication network N1 by wire or wirelessly, and follows a predetermined communication protocol with one or more user terminals 3 and the like via the communication network N1. Perform data communication.

The information processing unit 1 is a computer system having one or more processors such as a CPU (Central Processing Unit) and one or more memories such as a ROM (Read Only Memory) and a RAM, and is a computer system having various processes (information processing). To execute. The information processing unit 1 has functional units such as a designation unit 11, a creation processing unit 12, an information acquisition unit 13, a reference information designation unit 14, a correction time calculation unit 15, a presentation processing unit 16, a calculation unit 17, and a restriction unit 18. .. These plurality of functional units included in the information processing unit 1 may be distributed in a plurality of housings or may be provided in one housing.

The designation unit 11 executes a designation process for designating the field F1 as the target field. The “target field” referred to in the present disclosure is a field F1 that is a target for creating a work map M1 among the fields F1. That is, the work map creation system 10 creates a work map M1 for the field F1 designated as the target field by the designated unit 11. The "designation" referred to in the present disclosure includes not only an arbitrary designation by a person but also an automatically designated mode such as a value as a default is determined. In the present embodiment, the designation of the field F1 as the target field by the designated unit 11 is an arbitrary designation by a person, and in particular, it is performed according to the operation of the user (person) with respect to the user terminal 3. Specifically, the designation unit 11 designates one of the fields F1 as the target field according to the user's operation on the user terminal 3 received by the operation reception unit 22.

The creation processing unit 12 executes a creation process for creating the work support information D1. Since the work support information D1 includes the work map M1, the creation processing unit 12 creates the work map M1 for the field F1 designated as the target field according to the mapping conditions. The "mapping condition" referred to here is a condition (rule) determined when the work map M1 is created, and is included in the work map generation program and stored in advance in the data storage unit 21, for example. The details will be described later, but as an example, the mapping conditions are to create a work map M1 based on the amount of sprayed material calculated by the calculation unit 17, and to create a work map based on the reference map M2 (see FIG. 15). Includes creating M1 and the like.

The creation processing unit 12 can automatically create the work map M1 by following such a mapping condition. Specifically, the creation processing unit 12 sets the work area A1 corresponding to the target field, divides the entire work area A1 into a plurality of sections K in a mesh shape according to the mapping conditions, and "partitions K" for each section K. The work map M1 is created by assigning information such as "number" and "work index". Then, the creation processing unit 12 stores the work support information D1 including the created work map M1 in the work support information storage unit 211 of the data storage unit 21.

Further, in the present embodiment, the creation processing unit 12 has a plurality of modes including a new creation mode and a modification mode, and these modes can be switched according to the user's operation. Then, in the new creation mode, the creation processing unit 12 newly creates work support information D1 (work map M1) for the field F1 designated as the target field. On the other hand, in the modification mode, the creation processing unit 12 recreates the work support information D1 by modifying the work support information D1 created in the new creation mode. That is, in the present disclosure, the existing work support information D1 (work map M1) may be modified to be a new work support information D1 (work map M1), or the work support information D1 (work map M1) may be "created". ”. However, in the present embodiment, the creation of the work map M1 according to the mapping conditions is executed only in the new creation mode, and in the modification mode, the work map M1 is created according to the modification operation of the user.

In short, in the present embodiment, the operation reception unit 22 receives the user's correction operation for the work map M1 created by the creation processing unit 12. The creation processing unit 12 corrects the work index and recreates the work map M1 according to the correction operation. As an example, in a state where the work map M1 created by the creation processing unit 12 is displayed on the user terminal 3, the operation reception unit 22 accepts the user's correction operation for the work map M1.

More specifically, in the present embodiment, the creation processing unit 12 includes a condition determination unit 121, a new creation unit 122, and a correction processing unit 123. In other words, the work map creation system 10 according to the present embodiment includes a condition determination unit 121, a new creation unit 122, and a correction processing unit 123. The condition determination unit 121 determines the mapping condition. The new creation unit 122 creates the work support information D1 (work map M1) in the new creation mode. The correction processing unit 123 creates the work support information D1 (work map M1) in the correction mode.

By the way, as a related technique, there is a technique for creating a work map M1 such as a spray map corresponding to a field F1 based on an agricultural map such as a yield map. However, in the configuration of the related technique, when one field F1 is selected, a work map M1 for the one field F1 is created. Therefore, when creating the work map M1 for a plurality of fields F1, the user needs to repeat the procedure including the selection (designation) of the field F1 and the creation of the work map M1 for the number of fields F1. A large number of F1s can be a heavy burden.

On the other hand, the work map creation system 10 according to the present embodiment can reduce the burden on the user related to the creation of the work map M1 by the following configuration.

That is, in the present embodiment, the designated portion 11 is configured so that two or more fields F1 can be designated as the target field. In short, the designation unit 11 can not only designate one field F1 as a target field, but can also designate two or more fields, that is, a plurality of fields F1 as target fields. When two or more fields F1 are designated, the target field will include these two or more fields F1. Then, the creation processing unit 12 collectively creates work maps M1 corresponding to each of the two or more fields F1 according to the mapping conditions for the two or more fields F1 designated as the target fields. Each work map M1 has a plurality of compartments K for which a work index is set. Here, since one work map M1 is basically created for one field F1, the same number of work maps M1 as the field F1 designated as the target field are collectively created. That is, for example, if two fields F1 are designated as target fields, two work maps M1 are created, and if five fields F1 are designated as target fields, two work maps M1 are collectively created. ..

The term "collectively created" as used in the present disclosure means that they are created at the same time, and even if they are not created at the same time, they are created together. As an example, when two fields F1 are designated as target fields, a work map M1 for the two fields F1 is created without redesignating the fields F1 in a state where the two fields F1 are designated together. If so, the work map M1 is "created in a batch". On the other hand, when the field F1 is designated one by one for two or more fields F1 as the target fields and the work map M1 is created, the work map M1 is not "collectively created". In short, when the work map M1 is "created in a batch", the work of all the target fields is performed in the state where the target fields are collectively designated as the target fields for two or more fields F1 without redesignating the target fields. Map M1 will be created.

According to the above configuration, even when the work map M1 is created for two or more fields F1, the two or more fields F1 are collectively designated as the target fields, and the work map M1 is collectively created for these two or more fields F1. It becomes possible to do. Therefore, the user does not need to repeat the procedure including the selection (designation) of the field F1 and the creation of the work map M1 for the number of fields F1. As a result, according to the work map creation system 10 according to the present embodiment, it is possible to reduce the burden on the user related to the creation of the work map M1. In particular, in recent years, the number of cases in which the same user manages a large number of fields F1, which is tens or hundreds, is increasing, and for such users, the burden of creating the work map M1 is greatly reduced. Can be expected.

The information acquisition unit 13 executes an acquisition process for acquiring various information. The information acquisition unit 13 acquires various information from the inside of the management server 2 or from the outside of the management server 2.

In the present embodiment, the reference information is acquired from the outside of the management server 2.

The type acquisition unit 132 acquires type information. The type information is information regarding the type of the sprayed material used for the spraying work on the field F1. In the present embodiment, the spraying work is a fertilizer application work, and the sprayed material contains fertilizer. Therefore, the type information is information on the type of fertilizer. The type information includes, for example, information for identifying the fertilizer such as a fertilizer name, the content rate of a specific component in the sprayed material (fertilizer), the weight of the sprayed material (fertilizer) per bag, and the like. In the present embodiment, the type information is acquired from the inside of the management server 2.

The specific quantity acquisition unit 133 acquires the specific quantity information. The specific amount information is information on a specific amount which is a specific quantity per unit area of the field F1 for a specific component of the sprayed material. The "specific component" referred to here is one or more components of one or more components contained in the sprayed material, and basically, in the spraying work to the field F1, the field F1 is used as the main component of the sprayed material. It is a component that is expected to have an effect on. In this embodiment, since the sprayed product is fertilizer, the specific component contains nitrogen as an example. Then, the amount (spraying amount) per unit area of such a specific component is a "specific amount", and the specific amount information regarding this specific amount is acquired by the specific amount acquisition unit 133. In the present embodiment, the specific quantity information is acquired from the inside of the management server 2.

The spray amount acquisition unit 134 acquires the spray amount information. The spraying amount information is information on the spraying amount of the sprayed material per unit area of the field F1.

The "method of spraying work" referred to in the present disclosure includes the type, procedure, timing (including seasons, etc.) of the spraying work, the type of the work machine 4 to be used, and the like. In the present embodiment, since the spraying work is a fertilizer application work, the method of the spraying work includes the original fertilizer and the top fertilizer. Therefore, the work method information includes information for specifying whether the spraying work (fertilization work) is "primary fertilizer" or "additional fertilizer". Furthermore, "primary fertilizer" includes "full-thickness fertilizer" and "side-row fertilizer". That is, the work method information is, for example, information for distinguishing between "primary fertilizer" and "additional fertilizer", and in the case of "primary fertilizer", for distinguishing between "full-thickness fertilizer" and "side-row fertilizer". Includes information, etc. In the present embodiment, the work method information is acquired from the inside of the management server 2.

The reference information designation unit 14 executes a reference information designation process for designating reference information such as the reference map M2 corresponding to the field F1. That is, when it is stipulated that the work map M1 is created based on the reference map M2 as the mapping condition, the creation processing unit 12 is based on the reference map M2 designated by the reference information designation unit 14. , Create a work map M1. In the present embodiment, the designation of the reference information by the reference information designation unit 14 is an arbitrary designation by a person, and in particular, it is performed according to the operation of the user (person) with respect to the user terminal 3. Specifically, the reference information designation unit 14 designates the reference map M2 to be used as reference information according to the user's operation on the user terminal 3 received by the operation reception unit 22.

The correction time calculation unit 15 executes the correction time calculation process for calculating the total resource amount required for the work of the field F1 based on the corrected work map M1. The "total resource amount" as used in the present disclosure means the total amount of specific resources required for work. In the present embodiment, the work in the field F1 in which the work map M1 is used is a spraying work, particularly a fertilizer application work. Therefore, the “total resource amount” is an example of the total fertilizer application amount, that is, the field F1 corresponding to the work map M1. It is the amount of fertilizer applied (the amount of fertilizer) required for the entire fertilizer application work. In short, when the creation processing unit 12 corrects the work support information D1 created in the new creation mode in the correction mode, the total amount of resources required for the work based on the corrected work map M1 changes. The correction time calculation unit 15 obtains the total resource amount after the change due to the correction (that is, after the correction) by recalculation.

The presentation processing unit 16 executes a presentation process for presenting various information to the user. In the present embodiment, the presentation processing unit 16 is configured to be able to present at least the total amount of resources to the user. That is, when the corrected total resource amount is calculated by the correction time calculation unit 15, this total resource amount can be presented to the user by the presentation processing unit 16.

More specifically, the presentation processing unit 16 has a display processing unit 161. The display processing unit 161 executes a process of displaying various information including the corrected total resource amount and the like. In the present embodiment, the display processing unit 161 generates various screens such as the result list screen P1 (see FIG. 5) and the field setting screen P2 (see FIG. 6), and these screens are displayed on, for example, the user terminal 3. Displayed on the unit 33. The “screen” such as the result list screen P1 in the present disclosure means an image (image) displayed on the display unit, and includes an image, a figure, a photograph, a text, a moving image, and the like. Therefore, the information processing unit 1 can display or transmit the work map M1 or the like stored in the data storage unit 21 in response to an operation by the user on the operation reception unit 22, for example.

The calculation unit 17 executes a calculation process of calculating the sprayed amount of the sprayed material from the specific amount based on the type information. That is, according to the calculation unit 17, the amount of the sprayed material is determined from the specific amount represented by the specific amount information acquired by the specific amount acquisition unit 133 based on the type information acquired by the type acquisition unit 132. It is calculated. Specifically, the calculation unit 17 uses the content rate of the specific component in the spray (fertilizer) included in the type information, and uses the specific amount of the specific component per unit area (spray amount) to obtain the spray. Calculate the total spray amount.

By the way, as a related technique, a field showing a field F1 is divided into a plurality of areas, a mesh-type yield map to which harvest data is assigned to the areas is displayed, and each area is displayed on the same screen as the yield map. There is a technique to display a spray input unit for inputting a spray amount. This allows the user to create a work map M1 (scattering map) while looking at the yield map. However, in the above-mentioned related technique, when the user inputs the amount of spray for each area, the weight of the spray is input, but depending on the user, it is necessary to calculate the weight of the spray one by one, and as a result, the work map M1 The creation of work support information D1 such as, etc. can be a heavy burden. As an example, some users may focus on a specific component of fertilizer for each crop when the spray is fertilizer, and determine the spray amount based on the weight of the specific component. For such a user, input the spray amount. However, it is very troublesome, and the creation of the work support information D1 can be a heavy burden.

On the other hand, the work map creation system 10 (work support information creation system) according to the present embodiment aims to reduce the burden on the user related to the creation of the work support information D1 for a wide range of users by the following configuration. Make it possible.

That is, in the present embodiment, the creation processing unit 12 creates the work support information D1 based on the amount of the sprayed material calculated by the calculation unit 17. That is, even if the creation processing unit 12 does not directly use the spray amount information regarding the spray amount per unit area of the field F1, the calculation unit 17 can obtain the specific amount information acquired by the specific amount acquisition unit 133. The work support information D1 can also be created by using the calculated spraying amount.

According to the above configuration, for example, when the sprayed material is fertilizer, even a user who pays attention to a specific component of fertilizer for each crop and determines the spraying amount based on the weight of the specific component can be relatively easily achieved. Work support information D1 can be created. In short, for such a user, instead of the spraying amount (fertilizer application amount) of the sprayed material (fertilizer), a "specific amount" which is the amount per unit area of the field F1 for the specific component of the fertilizer may be input. .. Therefore, depending on the user, the information necessary for creating the work support information D1 can be obtained by inputting the specific amount for the specific component without directly inputting the spray amount of the spray material required for creating the work support information D1. Can be input. As a result, for example, even a user who pays attention to a specific component of fertilizer and determines the spraying amount based on the weight of the specific component does not need to calculate the weight of the sprayed material one by one, and works on the work map M1 or the like. The burden of creating the support information D1 can be significantly reduced. Therefore, according to the work map creation system 10 (work support information creation system) according to the present embodiment, it is possible to reduce the burden on the user related to the creation of the work support information D1 for a wide range of users.

Further, when the work support information D1 is created, the restriction unit 18 executes a restriction process for limiting the input set value input for the spray amount of the sprayed material. That is, in the present embodiment, when the creation processing unit 12 creates the work support information D1 based on the sprayed amount, the input setting value input for this sprayed amount is limited by the limiting unit 18. There is. The work support information D1 is information that supports the spraying work. The "restriction" as used in the present disclosure includes both an active restriction that positively restricts the input of an input set value and a negative restriction that passively restricts the input of an input set value. The positive restriction is embodied, for example, by invalidating the input of the input set value or prohibiting the transition to the option and the screen for inputting the input set value. Negative restrictions are embodied, for example, by displaying a caution statement such as "the upper limit is 100 kg / 10a" when inputting an input set value. In the present embodiment, the input set value is limited by limiting at least one of the upper limit, the lower limit and the range.

By the way, in the configuration of the above-mentioned related techniques, the spraying amount for each area is freely set by the user or automatically set according to the agricultural map, but the spraying amount may be inappropriate depending on the spraying work method. Can be set. As an example, when the sprayed material is fertilizer, the appropriate spraying amount differs greatly depending on whether the spraying work method (fertilizer application method) is the original fertilizer or the top fertilizer. Inappropriate spraying amount may be set due to misidentification.

On the other hand, the work map creation system 10 (work support information creation system) according to the present embodiment makes it easy to appropriately set the amount of sprayed material by the following configuration.

That is, in the present embodiment, the restriction unit 18 limits the input setting value input for the amount of sprayed material when the work support information D1 is created, based on the work method information. In short, when the limiting unit 18 limits the value (input set value) input for the spraying amount of the sprayed material, the limiting unit 18 limits the value based on the work method information acquired by the work method acquisition unit 135. Further, since the timing at which the input set value is restricted by the restriction unit 18 is when the work support information D1 is created, when the creation processing unit 12 creates the work map M1 in the new creation mode, the work map M1 is created in the modification mode. Can be included in any of the cases when creating.

According to the above configuration, the limiting unit 18 can limit the input set value so that an appropriate spraying amount according to the method of spraying work can be easily input. For example, when the sprayed material is fertilizer, the appropriate spraying amount differs greatly depending on whether the spraying work method (fertilizer application method) is the original fertilizer or the top fertilizer. The unit 18 limits the input set value. As a result, even if the user mistakenly determines the appropriate spraying amount according to the spraying work method, the limiting unit 18 limits the input of the incorrect spraying amount, and as a result, the appropriate spraying amount is set. It becomes easy to be done. Therefore, according to the work map creation system 10 (work support information creation system) according to the present embodiment, it becomes easy to appropriately set the spray amount of the sprayed material.

[6] Work Map Generation Method An example of a work map M1 generation method mainly executed by the information processing unit 1 of the management server 2 will be described with reference to FIGS. 4 to 18. Hereinafter, unless otherwise specified, the fertilizer application map used for the fertilizer spraying operation (that is, the fertilizer application operation) in the field F1 will be described as an example of the product (work map M1) by the method for producing the work map M1.

Further, since the method of generating the work map M1 according to the present embodiment is executed by the information processing unit 1 whose main configuration is the computer system, in other words, it is embodied in the work map generation program. That is, the work map generation program according to the present embodiment is a computer program for causing one or more processors to execute each process related to the generation method of the work map M1. Such a work map generation program may be executed in cooperation with, for example, the information processing unit 1 of the management server 2 and the control unit 31 of the user terminal 3.

Let me.

That is, as shown in FIG. 4, by the start operation, the result list screen P1 which is the home screen is first displayed on the display unit 33 of the user terminal 3. Then, when the new creation button B11 in the result list screen P1 is operated, the transition from the result list screen P1 to the field setting screen P2.

[6.1] Result list screen First, the result list screen P1 which is the home screen will be described. The result list screen P1 is a screen for displaying a list of simulation results. In this embodiment, the creation of the work map M1 is also referred to as "simulation". That is, the result list screen P1 displays a list of the work map M1 created (generated) by the method of generating the work map M1 as the simulation result. However, in the present embodiment, since the creation processing unit 12 can collectively create the work map M1 for two or more fields F1 as described above, two or more fields corresponding to these two or more fields F1 can be created at once. The work map M1 may be included in one simulation result.

As shown in FIG. 5, the result list screen P1 includes a list display area R11 and an operation area R12. In the list display area R11, the simulation result, that is, the information regarding the created work map M1 is displayed in a list.

Specifically, as an example, the list display area R11 displays a plurality of simulation results side by side in the vertical direction (vertical direction) so that each row corresponds to an individual simulation result (work map M1). The list display area R11 is divided into a plurality of items in the horizontal direction (horizontal direction), and information regarding each simulation result is divided into a plurality of items and displayed. In the example of FIG. 5, check boxes for selection, identification number, year, group name, simulation name, fertilization method, total fertilization amount, implementation date, and status items are displayed in order from the left. The selection check box is used to select the simulation result when outputting (writing to the recording medium 5) or deleting any of the simulation results. As an example, a crop variety is input to the group name. In addition, the current status of the simulation result is displayed in the status item.

In the example of FIG. 5, as the status, the characters (text) of "calculating", "result confirmation", or "result correction" are displayed. "Calculating" represents a state in which a simulation operation for creating a work map M1 is being executed. "Result confirmation" represents a state in which the simulation calculation for creating the work map M1 is completed and the work map M1 as the simulation result can be confirmed. The "result correction" represents a state in which the work map M1 has been corrected, that is, a state in which the work map M1 has been recreated. Here, states other than "calculating", that is, "result confirmation" and "result correction", are also used as objects of the result confirmation button B12 that can be operated respectively. Further, regarding "result confirmation", for example, the object (result confirmation button B12) is further divided into two states according to the display color, one color (red as an example) is an unconfirmed state, and the other color (green as an example). ) Indicates the confirmed status. A slide bar or a cursor may be displayed in the list display area R11, and the display contents of the list display area R11 may be scrollable in the vertical direction or the horizontal direction.

As an example, the operation area R12 displays an input field for searching the simulation result (work map M1) displayed in the list display area R11 under various search conditions. Further, in the operation area R12, a plurality of buttons to be operated by the user, such as a new creation button B11, an output button B13, a search button B14, and a delete button B15, are displayed. Specifically, search conditions such as year, fertilization method, and implementation date can be input in the input field, and when the search button B14 is operated with these search conditions input, the search conditions are input. The satisfied simulation result is displayed in the list display area R11. Regarding the implementation date, for example, the start (start of the implementation period) and the end (end of the implementation period) of the implementation period can be input so that the implementation period of the simulation can be specified as a search condition. Here, the information processing unit 1 searches the work support information storage unit 211 of the data storage unit 21 for the simulation result to be displayed in the list display area R11. The delete button B15 is a button for deleting the simulation result selected by the check box among the simulation results displayed in the list display area R11.

[6.2] Designation process Next, a "designation process" for designating the field F1 as the target field for which the work map M1 is created will be described. The designation process is executed when the creation process unit 12 newly creates the work map M1 in the new creation mode.

In the designation process, the display processing unit 161 causes the display unit 33 of the user terminal 3 to display the field setting screen P2. That is, when the new creation button B11 is operated on the result list screen P1, the designation process starts, and the screen displayed on the display unit 33 transitions from the result list screen P1 to the field setting screen P2.

The field setting screen P2 is a screen for designating the field F1 as the target field. In the present embodiment, a case where a field F1 as a target field is designated from a plurality of registered fields registered in advance in association with a user will be described as an example. Here, as a registration method of the registered field, for example, automatic registration in which the field F1 is automatically specified (extracted) and registered from the operation information (including the traveling route) of the work machine 4 and the user manually on the map or the like. There are two methods, manual registration, in which the field F1 is selected and registered in. Regardless of the method, the registration of the registered field is performed by storing the information about the field F1 in, for example, the data storage unit 21. Specifically, field identification information for identifying the field F1 such as the field name and address, information for specifying the position, shape, size, etc. of the field F1, and coordinate information of the outline of the field F1 as an example. Is stored in the data storage unit 21 as information about the registered field. The coordinate information is represented by, for example, latitude and longitude.

Further, in the registered field, work information regarding the work performed in the field F1 as the registered field is stored in association with each other. The work information includes, for example, the type of work (including sowing, rice planting, fertilization, harvesting, etc.), the operation information of the work machine 4 used for the work (including the traveling route), the work time, and the work efficiency (area / work time). Includes information such as fertilizer application amount, planting depth, soil characteristics (including soil hardness and board depth, etc.), tillage depth and lift angle. Furthermore, as a result of the work, information such as the yield (yield) of the crop grown in the field F1, the taste of the crop (including protein content or water content, etc.), and the growth status of the crop is also used as work information. It is stored in association with the registered field. Various performance maps such as yield map, taste map, growth map, soil map and performance fertilization map generated based on these work information are also stored as work information in association with the registered field.

The yield map is map data in which when the field F1 is divided into a plurality of areas, the yield for each area (average yield per unit area, etc.) is assigned to each area. The taste map is map data in which when the field F1 is divided into a plurality of areas, the taste such as the protein content or the water content of each area is assigned to each area. The growth map is map data in which the growth status of crops in each area is assigned to each area when the field F1 is divided into a plurality of areas. As for the growth situation of the crop, as an example, the field F1 in which the crop is cultivated is imaged from the sky with a drone or the like, and the captured image is taken as NDVI, DVI, RVI, GNDVI, SAVI, TSAVI, CAI, MTCI, REP, PRI or RSI. It is obtained by analysis with various vegetation indexes such as. In particular, a growth map obtained by a Normalized Difference Vegetation Index (NDVI) is also referred to as an "NDVI map". The soil map is map data in which soil characteristics including soil hardness and hard disk depth for each area are assigned to each area when the field F1 is divided into a plurality of areas. The actual fertilizer application map is map data in which the fertilizer application amount (fertilizer application amount) for each area is assigned to each area when the field F1 is divided into a plurality of areas, and is a map used for past fertilizer application work. Data, that is, map data showing the results of past fertilizer application work. In the present embodiment, these actual maps associated with the field F1 as the registered field are used as the reference map M2 which is an example of the reference information.

Further, the work information as described above also includes time information (start date and time and end date and time as an example) related to the work. As a result, the work information is stored in a mode in which it is possible to specify when the actual work is performed with respect to the actual results map such as the yield map, the taste map and the growth map. For example, even for the same field F1, it is possible to register a yield map, a taste map, a growth map, etc. for each year.

As shown in FIG. 6, the field setting screen P2 includes a field designated area R21 and an operation area R22. In the field designation area R21, information for designating the field F1 as the target field is displayed. That is, the user selects an arbitrary field F1 from the plurality of fields F1 registered as registered fields in the field designated area R21 of the field setting screen P2 displayed on the display unit 33 of the user terminal 3. Designate as a target field.

Specifically, the field designated area R21 includes, as an example, an image Im2 such as a map or an aerial photograph for designating the field F1 and a list of the fields F1 designated as the target field. Therefore, the designation unit 11 designates the target field according to the operation of the user who designates the field F1 on the image Im2. The image Im2 includes at least one field F1, and on the image Im2, the user performs an operation of selecting an arbitrary field F1 with, for example, a cursor or the like, so that the arbitrary field F1 is set as the target field. specify.

In the example of FIG. 6, five fields F11 to F15 are displayed in the image Im2, and the user designates all of these five fields F11 to F15 as target fields. Therefore, on the right side of the image Im2 in the field designated area R21, the field F11 "field 6", the field F12 "field 10", the field F13 "field 3", and the field F14 "field 4", “Field 8”, which is the field F15, is displayed side by side. Here, the field setting screen P2 displays the designated target fields side by side in the vertical direction (vertical direction) so that each row corresponds to the individual field F1.

Then, the information of the designated reference map M2 is displayed side by side in each target field. Here, when a plurality of performance maps are associated with the field F1 designated as the target field, the performance map designated as the reference map M2 can be switched to another performance map. On the other hand, if the reference map M2 is not specified for the field F1 designated as the target field because the actual map is not associated with the field F1, the information of the reference map M2 is displayed as "None". .. In the example of FIG. 6, for "field 6" (field F11) and "field 10" (field F12), the growth map (NDVI map) of June 2019 is designated as the reference map M2. The reference map M2 is not specified for the other fields F13 to F15.

Further, the specific means for designating the field F1 as the target field is not limited to the above example. For example, the user may specify the field F1 included in the arbitrary range as the target field by performing an operation of designating an arbitrary range on the image Im2 with a cursor or the like. In this case, if a plurality of fields F1 are included in the arbitrary range, these plurality of fields F1 are collectively designated as the target field. Further, the user may specify the field F1 as the target field by inputting, for example, information that can identify the field F1 such as a field name, an address, or latitude and longitude. Further, in the image Im2, operations such as map / aerial photograph switching, scrolling, enlargement / reduction, and page switching can be performed according to the user's operation.

In the operation area R22, as an example, an input field for searching a registered field under various search conditions such as a year, a crop, a variety, and a group name is displayed. The field F1 displayed in the image Im2 is narrowed down according to the year and crops input in this input field. Further, in the operation area R22, a parameter setting button B21, a field number setting button B22, B23 for setting the number of fields, a method setting button B24 for setting a fertilization method (spraying work method), a back button B25, etc. , Multiple buttons to be operated by the user are displayed. The field number setting buttons B22 and B23 are radio buttons for selecting whether to specify a plurality of fields F1 or a single field F1 as the target fields for creating the work map M1. By selecting the field number setting button B22, it is possible to specify a plurality of fields F1 as the target field, and by selecting the field number setting button B23, it is possible to specify a single field F1 as the target field. The method setting button B24 is a radio button for selecting one of the three fertilization methods: full-thickness fertilization, side-row fertilization, and top dressing. Full-thickness fertilization and side-row fertilization are included in "primary fertilizer". The back button B25 is a button for returning to the previous screen, that is, the result list screen P1.

By the way, in the present embodiment, the priority is set for the reference map M2. Then, for the field F1 to which a plurality of reference maps M2 are designated, which reference map M2 is used for creating the work map M1 is determined according to this priority. Therefore, for the field F1 to which a plurality of reference maps M2 are designated, the reference map M2 having the highest priority (first priority) among them is displayed by default in the field designation area R21 on the field setting screen P2. The map. That is, for the field F1 to which the plurality of reference maps M2 are designated, the creation processing unit 12 creates the work map M1 based on one or more reference maps M2 selected according to the priority among the plurality of reference maps M2. create. Specifically, the condition determination unit 121 of the creation processing unit 12 determines the reference map M2 to be used for creating the work map M1 by referring to the priority order. As a result, the creation processing unit 12 uses the reference map M2 having the highest priority in order, and for the field F1 to which the reference map M2 having the highest priority is not associated, the reference map M2 having the next highest priority is used. Use to create a work map M1.

Such a priority is arbitrarily set by the user on, for example, the priority setting screen P21 as shown in FIG. 7. As an example in FIG. 7, the priority setting screen P21 can set the reference map M2 as the first priority, the second priority, and the third priority for each fertilization method (spraying work method). In the example of FIG. 7, for "full-thickness fertilization", the growth map (NDVI map) of the previous autumn is set as the first priority, the yield map of the previous year is set as the second priority, and the soil fertility map is set as the third priority. .. Therefore, in the field F1 where full-thickness fertilization is performed, the growth map of the previous year is referred to if the growth map of the previous autumn is associated, and the yield map of the previous year is referred to if the growth map of the previous autumn is not associated. It is used as the map M2 to create the work map M1. Further, when the reference map M2 is not set in any of the first priority, the second priority, and the third priority, it is considered that the reference map M2 is not specified. The priority is set for each user, for example.

[6.3] Parameter setting process Next, a “parameter setting process” for setting the parameters used for creating the work map M1 will be described. The parameter setting process is executed when the creation process unit 12 newly creates the work map M1 in the new creation mode.

In the parameter setting process, the display processing unit 161 displays the parameter setting screen P3 on the display unit 33 of the user terminal 3. That is, when the parameter setting button B21 is operated on the field setting screen P2, the parameter setting process starts, and the screen displayed on the display unit 33 transitions from the field setting screen P2 to the parameter setting screen P3.

The parameter setting screen P3 is a screen for setting parameters used for creating the work map M1. The "parameter" referred to here includes information on the sprayed material (fertilizer) sprayed in the spraying operation, and includes a standard fertilizer application amount as an example. The "standard fertilizer application amount" is a standard fertilizer application amount per unit area defined for a certain field F1, and is expressed in units of, for example, "kg / 10a". That is, the parameter set on the parameter setting screen P3 includes at least the amount of sprayed material (fertilizer application amount).

As shown in FIG. 8, the parameter setting screen P3 includes a setting area R31 and a reference area R32. Information for setting parameters is displayed in the setting area R31. That is, the user inputs the parameters used for creating the work map M1 in the setting area R31 of the parameter setting screen P3 displayed on the display unit 33 of the user terminal 3. Further, in the reference area R32, the "maximum value", "mode" and "minimum value" of the NDVI value for the field F1 designated as the target field are displayed for reference.

Specifically, the setting area R31 includes, as an example, a plurality of input fields C31 to C38, and a plurality of buttons to be operated by the user, such as a creation button B31, a back button B32, and a reference button B33. .. The input field C31 is the fertilizer name, the input field C32 is the nitrogen content, the input field C33 is the weight per bag, the input field C34 is the standard fertilizer application amount, and the input field C35 is the nitrogen weight, for example, in free text. This is an area for input. The maximum fertilizer application amount that can be input as the standard fertilizer application amount is automatically inserted into the input field C36, and the minimum fertilizer application amount that can be input as the standard fertilizer application amount is automatically inserted into the input field C37. The input field C38 is an area for inputting the mesh size of the work map M1, that is, the size of the section K, for example, by a selection method. The back button B32 is a button for returning to the previous screen, that is, the field setting screen P2. The reference button B33 is a button for referring to the input history of the past parameters and quoting the parameters from the input history.

For example, when the reference button B33 is operated, the reference screen P31 as shown in FIG. 9 is displayed on the display unit 33. The reference screen P31 is a screen based on the input history on the parameter setting screen P3, and displays items such as the fertilizer name, the nitrogen content, and the weight per bag that have been input in the past. When an arbitrary fertilizer is selected on the reference screen P31 and the reflection button B311 is operated, the information of the selected fertilizer is automatically inserted into the input fields C31 to C33. It is also possible to delete an unnecessary input history by operating the delete button B312 in the reference screen P31. In the example of FIG. 9, the reference screen P31 is displayed as a pop-up window on the parameter setting screen P3, but the present invention is not limited to this example, and the parameter setting screen P3 may be switched to the reference screen P31.

By the way, in the present embodiment, the calculation unit 17 executes the calculation process while the parameter setting screen P3 is being displayed. That is, since the creation processing unit 12 creates the work support information D1 based on the spraying amount calculated by the calculation unit 17, the parameter setting screen P3 for inputting the spraying amount (standard fertilizer application amount) of the sprayed material. During the display, the calculation process by the calculation unit 17 is executed. The calculation unit 17 calculates the sprayed amount from the specific amount represented by the specific amount information acquired by the specific amount acquisition unit 133 based on the type information acquired by the type acquisition unit 132. Specifically, the calculation unit 17 calculates the standard fertilizer application amount from the nitrogen weight input to the input field C35 based on the type information including the nitrogen content input to the input field C32. Then, the standard fertilizer application amount calculated by the calculation unit 17 is automatically inserted into the input field C34.

As a result, for example, when the user inputs the nitrogen weight in the input field C35 as shown in the upper part of FIG. 10, the standard fertilizer application amount is automatically input in the input field C34 as shown in the lower part of FIG. become. In the example of FIG. 10, since "33.00 kg / 10a" is input as the nitrogen weight, the calculation unit 17 divides "33.00" by the nitrogen content in the type information to obtain a sprayed product (33.00 kg / 10a). Calculate the amount of fertilizer (fertilizer) sprayed. The spraying amount calculated in this way (“73.33 kg / 10a” in the example of FIG. 10) is automatically input to the input field C34 as the standard fertilizer application amount. Therefore, even a user who pays attention to a specific component of fertilizer (for example, nitrogen) for each crop and determines the spraying amount based on the weight of the specific component can relatively easily input the standard fertilizer application amount.

Here, in the present embodiment, the work support information D1 includes a work map M1 having a plurality of sections K. Therefore, the standard fertilizer application amount calculated by the calculation unit 17 is reflected in the work indexes of the plurality of sections K in the work map M1. In other words, the creation processing unit 12 sets the work index of each of the plurality of sections K in the work map M1 based on the spray amount of the sprayed material calculated by the calculation unit 17.

Further, in the present embodiment, the user can directly input the standard fertilizer application amount to the input field C34. When the standard fertilizer application amount is directly input to the input field C34, the standard fertilizer application amount is acquired as the application amount information by the application amount acquisition unit 134. Then, when the spray amount information is acquired by the spray amount acquisition unit 134, the creation processing unit 12 replaces the spray amount calculated by the calculation unit 17 with the work support information D1 based on the spray amount information. To create. That is, when the standard fertilizer application amount is directly input to the input field C34, the standard fertilizer application amount is used for creating the work map M1 instead of the standard fertilizer application amount calculated by the calculation unit 17. As a result, even a user who determines the spraying amount based on the fertilizer application amount (standard fertilizer application amount) instead of the specific amount can easily input the standard fertilizer application amount.

Further, when the spraying amount information is acquired by the spraying amount acquisition unit 134, the calculation unit 17 calculates a specific amount from the sprayed amount of the sprayed material based on the type information. Specifically, the calculation unit 17 calculates the nitrogen weight as a specific amount by multiplying the spray amount (standard fertilizer application amount) acquired by the spray amount acquisition unit 134 by the nitrogen content in the information. In short, the calculation unit 17 not only calculates the spraying amount (standard fertilizer application amount) from the specific amount (nitrogen weight), but also calculates the specific amount (nitrogen weight) from the spraying amount (standard fertilizer application amount). It is possible. Therefore, the specific amount (nitrogen weight) and the spraying amount (standard fertilizer application amount) have a relationship that can be mutually converted by the calculation unit 17.

Further, in the present embodiment, the display processing unit 161 displays both the specific amount and the sprayed amount on one screen. Specifically, as illustrated in FIG. 10, in the parameter setting screen P3, a specific amount (nitrogen weight) is displayed in the input field C35, and a sprayed amount (standard fertilizer application amount) is displayed in the input field C34. To. This makes it easy to visually compare the specific amount and the sprayed amount of the sprayed material.

Further, in the present embodiment, the limiting unit 18 executes the limiting process while the parameter setting screen P3 is being displayed. That is, since the creation processing unit 12 creates the work support information D1 based on the spraying amount of the sprayed material whose input set value is limited by the limiting unit 18, the spraying amount (standard fertilizer application amount) of the sprayed material is input. While the parameter setting screen P3 is being displayed, the restriction process by the restriction unit 18 is executed. When creating the work support information D1, the limiting unit 18 limits the input setting value input for the spraying amount of the sprayed material based on the work method information. Specifically, the restriction unit 18 sets an input setting value of the standard fertilizer application amount input to the input field C34 based on the fertilizer application method (full-thickness fertilization, side row fertilization or topdressing) selected on the field setting screen P2. Restrict. Therefore, considering that the amount of fertilizer required differs depending on the type of fertilizer application method, it is possible to suppress the input of unnecessary fertilizer amount in advance.

In the present embodiment, as an example, the restriction unit 18 implements both positive restriction and negative restriction of input of the input set value. As a positive restriction, for example, when limiting the upper limit of the input set value, the restriction unit 18 prohibits the input of a value equal to or more than the upper limit of the standard fertilizer application amount input to the input field C34. As a negative limitation, for example, when limiting the upper limit of the input set value, the limiting unit 18 automatically inserts the upper limit into the input field C36, and when limiting the lower limit of the input set value, the lower limit thereof. The value is automatically inserted in the input field C37. As a result, the user can input the standard fertilizer application amount after grasping the standard fertilizer application amount that can be input by displaying the input field C36 and the input field C37, and if the input is incorrect, the incorrect input is prohibited. To. In the present embodiment, the standard fertilizer application amount calculated from the nitrogen weight may be input by the calculation unit 17, and in this case, the restriction unit 18 limits the input set value of the nitrogen weight to make a standard. Indirectly limit the input setting value of fertilizer application amount. Further, in the variable fertilization map described later, the input set value can be limited by the limiting unit 18 not only for the upper limit value and the lower limit value but also for the range of variation in the fertilization amount.

More specifically, in the present embodiment, since the method of spraying work (fertilization method) includes the original fertilizer and the top fertilizer, the limiting unit 18 changes the limitation of the input set value depending on whether the fertilizer application method is the original fertilizer or the top fertilizer. .. In particular, the limiting unit 18 limits the upper limit of the input set value to be smaller for topdressing than in the case of the original fertilizer. As a result, when the user sets the standard fertilizer application amount on the parameter setting screen P3, if the fertilizer application method is top fertilization, the upper limit of the standard fertilizer application amount that can be input is smaller than that in the case of the original fertilizer. Therefore, the setting of the excessive fertilizer application amount in the top dressing is automatically suppressed.

Further, in the present embodiment, since the original fertilizer includes full-thickness fertilization and side-row fertilization, the restriction unit 18 changes the limitation of the input set value depending on whether the fertilization method is full-thickness fertilization or side-row fertilization. In particular, the limiting unit 18 limits the upper limit of the input set value to be smaller for side-row fertilization than in the case of full-thickness fertilization. As a result, when the user sets the standard fertilization amount on the parameter setting screen P3, if the fertilization method is side-row fertilization, the upper limit of the standard fertilization amount that can be input is smaller than that in the case of full-thickness fertilization. Will be done. Therefore, even in the case of the original fertilizer application, when there is a clear difference in the required fertilizer application amount in principle, the setting of the excessive fertilizer application amount is automatically suppressed. Here, in the case of top dressing, the upper limit of the input set value is further limited as compared with the case of side strip fertilization.

Further, the work method information includes the type of the work machine 4 used for the spraying work. Therefore, as an example, the restriction unit 18 may change the restriction of the input set value depending on whether the type of the work machine 4 is a sprayer for full-thickness fertilization or a sprayer for side-row fertilization. Further, since the type of the work machine 4 includes, for example, a rice transplanter, a tractor, and a drone, the restriction unit 18 inputs, for example, depending on whether the type of the work machine 4 is a rice transplanter, a tractor, or a drone. You may change the limit of the set value.

[6.4] Creation process Next, the "creation process" for creating the work map M1 will be described. Here, first, the creation process in which the creation processing unit 12 newly creates the work map M1 in the new creation mode will be described.

While the creation process is being executed, the display processing unit 161 causes the display unit 33 of the user terminal 3 to display the result list screen P1. Specifically, when the creation button B31 is operated on the parameter setting screen P3, the creation process starts, and the screen displayed on the display unit 33 transitions from the parameter setting screen P3 to the result list screen P1. Then, while the creation process is being executed, the status of the result list screen P1 is "calculating". When the creation process is completed, the display processing unit 161 can display the result confirmation screen P4 on the display unit 33 of the user terminal 3. That is, the status of the result list screen P1 becomes "result confirmation", and when the result confirmation button B12 is operated in this state, the screen displayed on the display unit 33 changes from the result list screen P1 to the result confirmation screen P4. Transition.

The result confirmation screen P4 is a screen for confirming the created work map M1. As shown in FIG. 11, the result confirmation screen P4 includes an image Im4 such as a map or an aerial photograph for displaying the work map M1, a comparison button B41, a correction button B42, a back button B43, a save button B44, and the like. It includes multiple buttons to be operated. Further, the result confirmation screen P4 has a display column C41 for displaying the total fertilizer application amount (total resource amount) below the image Im4. The back button B43 is a button for returning to the result list screen P1. The save button B44 is a button for saving the simulation result (work map M1).

The image Im4 includes at least one work map M1, and the user confirms the work map M1 on the image Im4. In the example of FIG. 11, five work maps M11 to M15 corresponding to the five fields F11 to F15 are displayed in the image Im4. Here, the work map M11 corresponding to the field F11 and the work map M12 corresponding to the field F12 are variable fertilization maps, and the other work maps M13 to M15 are uniform fertilization maps. The "variable fertilizer application map" referred to in the present disclosure is a work map M1 in which the work index (fertilizer application amount) varies among a plurality of sections K set in the work area A1 corresponding to the field F1. The "uniform fertilization map" referred to in the present disclosure has no variation in the work index (fertilization amount) among the plurality of sections K set in the work area A1 corresponding to the field F1, that is, uniform for the plurality of sections K. It is a work map M1 in which a work index is set in. Therefore, the work maps M13 to M15, which are uniform fertilizer application maps, are displayed in "solid paint" in which the work area A1 is uniformly filled.

The variable fertilization map and the uniform fertilization map can be easily distinguished on the image Im4, but the display mode may be changed between the variable fertilization map and the uniform fertilization map so as to be easier to distinguish. For example, as shown in FIG. 11, the display processing unit 161 can make it easier to distinguish between the variable fertilization map and the uniform fertilization map by differentiating the line type or color of the outer periphery of the work map M1 from the variable fertilization map and the uniform fertilization map. ..

Here, whether to create a variable fertilization map or a uniform fertilization map is determined by the mapping conditions. Specifically, either the variable fertilization map or the uniform fertilization map is selectively created depending on whether or not the reference map M2 is designated corresponding to the field F1. When the reference map M2 is specified, the mapping conditions are specified so that the variable fertilization map is created. In short, the mapping condition is the work map M1 (variable fertilization map) in which the work index is individually set for a plurality of sections K based on the reference map M2 if the reference map M2 is specified corresponding to the field F1. Including, to create. Further, the mapping condition includes setting the work index uniformly for a plurality of sections K if the reference map M2 is not specified corresponding to the field F1.

By following such mapping conditions, a variable fertilization map is created for the field F1 to which the reference map M2 is specified, and a uniform fertilization map is created for the field F1 to which the reference map M2 is not specified. The map. Therefore, in the example of FIG. 11, the variable fertilization map is created only for the fields F11 and F12 to which the reference map M2 is designated. That is, in each of the fields F11 and F12, the growth map (NDVI map) of June 2019 is designated as the reference map M2. Therefore, the work maps M11 and M12 of the fields F11 and F12 are variable fertilization maps created based on the growth map. More specifically, the preparation processing unit 12 works so as to promote the growth by increasing the amount of fertilizer applied to the position in the field F1 where the growth of the crop is determined to be delayed based on the growth map. Create map M1. Therefore, basically, a work map M1 that looks like an inverted growth map is generated.

Here, in the present embodiment, as described above, various performance maps such as a yield map, a taste map, a growth map, a soil map, and a performance fertilization map are used as the reference map M2.

In short, the reference map M2 includes a growth map showing the distribution of crop growth in the field F1. This makes it possible to create a work map M1 that promotes the growth of the crop when the growth is delayed. Then, the growth map shows the growth situation for each of a plurality of small areas (areas) in the field F1. The work map M1 created based on such a growth map has a plurality of sections K corresponding to a plurality of small areas (areas). This makes it possible to create a precise work map M1 that reflects the growth status of each section K.

The reference map M2 also includes a yield map showing the distribution of crop yields within the field F1. This makes it possible to create a work map M1 that promotes growth when the yield of crops is small. Then, the yield map shows the yield for each of a plurality of small areas (areas) in the field F1. The work map M1 created based on such a yield map has a plurality of compartments K corresponding to a plurality of small areas (areas). This makes it possible to create a precise work map M1 that reflects the yield for each section K.

Next, an example of the processing procedure of the management server 2 related to the creation process will be described with reference to FIGS. 12 to 14. The details of the calculation-related process (S7) in FIG. 12 including a series of processes related to the calculation process are shown in the flowchart of FIG. The details of the restriction-related processing (S8) in FIG. 12, including a series of processing related to the restriction processing, are shown in the flowchart of FIG.

As shown in FIG. 12, the information processing unit 1 of the management server 2 starts the designation process (S2) when the new creation button B11 in the result list screen P1 is operated (S1: Yes). Specifically, the information processing unit 1 of the management server 2 causes the display unit 33 of the user terminal 3 to display the field setting screen P2 (S3). In this state, the information processing unit 1 of the management server 2 accepts the designation of the field F1 as the target field.

In step S4, when the parameter setting button B21 in the field setting screen P2 is operated (S4: Yes), the information processing unit 1 of the management server 2 starts the parameter setting process (S5). Specifically, the information processing unit 1 of the management server 2 causes the display unit 33 of the user terminal 3 to display the parameter setting screen P3 (S6). In this state, the information processing unit 1 of the management server 2 receives input of parameters for creating the work map M1 while executing the calculation-related processing (S7) and the restriction-related processing (S8).

In step S9, when the creation button B31 in the parameter setting screen P3 is operated (S9: Yes), the information processing unit 1 of the management server 2 determines whether or not the reference map M2 is specified for the field F1 as the target field. Is determined (S10). For the field F1 to which the reference map M2 is designated (S10: Yes), the information processing unit 1 of the management server 2 acquires the reference information regarding the reference map M2 (S11), and the variable fertilization map is based on the reference map M2. Is created (S12). On the other hand, for the field F1 to which the reference map M2 is not designated (S10: No), the information processing unit 1 of the management server 2 creates a uniform fertilization map (S13).

In step S14, the information processing unit 1 of the management server 2 determines whether or not the work map M1 creation process has been completed for all the fields F1 designated as the target fields. That is, when two or more fields F1 are designated as target fields in the designated process (S2), the information processing unit 1 of the management server 2 executes steps S10 to S14 for all of these two or more fields F1. do. As a result, the creation processing unit 12 collectively creates work maps M1 corresponding to each of the two or more fields F1 for the two or more fields F1 designated as the target fields according to the mapping conditions. When the work map M1 creation process is completed for all the fields F1 designated as the target fields (S14: Yes), the information processing unit 1 of the management server 2 registers the work map M1 (S15) and creates the work map M1. End the process.

Further, in the calculation-related processing, as shown in FIG. 13, in step S71, the information processing unit 1 of the management server 2 determines whether or not a specific amount of input is input. At this time, the information processing unit 1 determines that the nitrogen weight as a specific quantity has been input because the data (value) is input to the input field C35 of the parameter setting screen P3 (S71: Yes), and steps the process. Move to S72.

In step S72, the type acquisition unit 132 of the information processing unit 1 acquires the type information. At this time, the type acquisition unit 132 acquires the nitrogen content and the like input in the input field C32 as the type information. Then, in step S73, the specific quantity acquisition unit 133 of the information processing unit 1 acquires the specific quantity information. At this time, the specific quantity acquisition unit 133 acquires the nitrogen weight input to the input field C35 as the specific quantity information.

In step S73, the calculation unit 17 of the information processing unit 1 executes a calculation process of calculating the spray amount from the specific amount. Specifically, the calculation unit 17 calculates the standard fertilizer application amount as the spraying amount from the nitrogen weight as the specific amount. The standard fertilizer application amount calculated by the calculation unit 17 is automatically inserted into the input field C34.

Further, in the restriction-related processing, as shown in FIG. 14, in step S81, the work method acquisition unit 135 of the information processing unit 1 acquires the work method information. At this time, the work method acquisition unit 135 acquires the fertilizer application method selected from the three layers of full-thickness fertilization, side row fertilization, and top dressing as work method information by the method setting button B24 on the field setting screen P2.

In step S82, the information processing unit 1 of the management server 2 determines whether or not the work method is top dressing. When topdressing is selected by the method setting button B24 on the field setting screen P2, the information processing unit 1 determines that the work method is topdressing (S82: Yes), and the limiting unit 18 sets the upper limit of the input setting value. Set to V1 (S84). On the other hand, when the main fertilizer (full-thickness fertilization or side-row fertilization) is selected by the method setting button B24 on the field setting screen P2, the information processing unit 1 determines that the work method is not top dressing (S82: No) and processes it. To step S83.

In step S83, the information processing unit 1 of the management server 2 determines whether or not the work method is side-row fertilization. When side row fertilization is selected by the method setting button B24 on the field setting screen P2, the information processing unit 1 determines that the work method is side row fertilization (S83: Yes), and the restriction unit 18 inputs the input setting value. The upper limit of is set to V2 (S85). On the other hand, when full-thickness fertilization is selected by the method setting button B24 on the field setting screen P2, the information processing unit 1 determines that the work method is not side-row fertilization (S83: No), and shifts the process to step S86. do.

In step S86, the limiting unit 18 of the information processing unit 1 sets the upper limit of the input set value to V3. Here, as for the upper limit values of "V1", "V2", and "V3", "V1" is the smallest and increases in the order of "V2" and "V3" (V1 <V2 <V3). According to the input setting value in which the upper limit value is set in this way, the limiting unit 18 limits the input of the standard fertilizer application amount to the input field C34 of the parameter setting screen P3.

However, the flowcharts shown in FIGS. 12 to 14 are merely examples, and the processes may be added or omitted as appropriate, or the order of the processes may be changed as appropriate.

By the way, when the work map M1 is created by the creation process, the result comparison screen P5 as illustrated in FIG. 15 can be displayed. That is, when the comparison button B41 is operated on the result confirmation screen P4, the screen displayed on the display unit 33 transitions from the result confirmation screen P4 to the result comparison screen P5.

As shown in FIG. 15, the result comparison screen P5 has a comparison area R51 and an information area R52. In the information area R52, various information regarding the user (owner), the field F1, the fertilizer application work, and the like are displayed. In the comparison area R51, the created work map M1 and the reference map M2 used for creating the work map M1 are displayed side by side. As a result, the user can confirm the reference map M2, which is the basis for creating the work map M1, together with the work map M1 on the result comparison screen P5. Therefore, the user can easily evaluate the work map M1.

[6.5] Correction process Next, a "correction process" for modifying the work map M1 will be described. The correction process is a process in which the creation processing unit 12 recreates the work map M1 in the modification mode, and can be executed after the work map M1 is created in the new creation mode.

In the correction process, the display processing unit 161 displays the result correction screen P6 on the display unit 33 of the user terminal 3. That is, when the correction button B42 is operated on the result confirmation screen P4, the screen displayed on the display unit 33 transitions from the result confirmation screen P4 to the result correction screen P6.

As shown in FIG. 16, the result correction screen P6 includes an image Im6 including the work map M1 and an operation area R61. As an example, the operation area R61 displays a plurality of buttons to be operated by the user, such as the correction method selection buttons B61 and B62, the slide bar B63, the correction button B64, the recalculation button B65, and the save button B66. The correction method selection buttons B61 and B62 are radio buttons for selecting whether the target for correction of the work map M1 is the entire field F1 or the correction range Z61 specified on the result correction screen P6. be. By selecting the correction method selection button B61, the entire field F1 can be corrected as a unit, and by selecting the correction method selection button B62, the correction range can be freely specified by the correction range Z61 instead of the field F1 unit. Will be.

That is, when the correction method selection button B62 is selected, a frame representing the correction range Z61 is displayed on the image Im6 as shown in FIG. The user sets the correction range Z61 to an arbitrary shape and size on the image Im6 with a cursor or the like. As a result, among the plurality of sections K of the work map M1, the section K included in the correction range Z61 can be the target of the correction of the work index. In short, the creation processing unit 12 corrects the work index for the correction range Z61 designated on the result correction screen P6 including the work map M1.

The modification of the work map M1 is performed by the modification of the work index. That is, the work map M1 is modified by changing the value of the work index. Here, the work index is changed by operating the slide bar B63 or the correction button B64. Then, in the present embodiment, when the work index has a variation in a plurality of sections K as in the variable fertilization map, the work index is corrected while maintaining this variation. In the example of FIG. 16, the working index of the section K in the correction range Z61 is uniformly changed while maintaining the distribution. In short, in the present embodiment, when the work index is individually set for the plurality of sections K, the creation processing unit 12 corrects the work index while maintaining the distribution of the work index. However, this configuration is not essential, and for example, the variable fertilization map may be modified to the work map M1 which does not have the distribution of the work index like the uniform fertilization map.

Further, the result correction screen P6 has a display column C61 for displaying the total fertilizer application amount (total resource amount) below the image Im6. In this display column C61, the result of recalculation of the total resource amount for the corrected work map M1 by the correction calculation unit 15 is displayed. Specifically, when the recalculation button B65 is operated, the correction calculation unit 15 recalculates the total fertilizer application amount (total resource amount) based on the corrected work map M1 and displays it in the display column C61. .. As a result, the user can easily grasp that the total fertilizer application amount to be used is significantly different from the initially assumed amount by modifying the work map M1.

That is, in the present embodiment, the operation reception unit 22 receives the user's correction operation for the work map M1 created by the creation processing unit 12. Then, the creation processing unit 12 can modify the work index and recreate the work map M1 according to the correction operation. Here, the restriction unit 18 also limits the input set value when creating the work map M1 when the creation processing unit 12 corrects the work index. In short, in the present embodiment, the restriction unit 18 limits the input set value when the creation processing unit 12 creates the work support information D1 when the work support information D1 is recreated. Specifically, the range in which the work index can be modified is limited by the restriction unit 18 limiting the input set value. In this way, regardless of whether the creation processing unit 12 is in the new creation mode or the modification mode, the restriction unit 18 supports input of parameters (standard fertilizer application amount). The save button B66 is a button for saving the corrected simulation result (work map M1).

By the way, in the present embodiment, if a plurality of fields F1 are selected as correction targets on the result correction screen P6, it is possible to collectively correct these plurality of fields F1. That is, as shown in FIG. 17, by setting the correction range Z61 across the plurality of work maps M1, these plurality of work maps M1 can be corrected at once. In short, when the correction range Z61 is specified across a plurality of fields F1, the creation processing unit 12 corrects the work index for the plurality of fields F1 at once. As a result, for example, in the case of making corrections across a plurality of fields F1 such as uniformly increasing the amount of fertilizer applied to a plurality of fields F1 in the northern range, the burden on the user is greatly reduced.

[6.6] Output processing Next, "output processing" for outputting the work map M1 will be described.

In the output processing, the display processing unit 161 causes the display unit 33 of the user terminal 3 to display the output screen P7. That is, when the output button B13 is operated on the result list screen P1, the screen displayed on the display unit 33 transitions from the result list screen P1 to the output screen P7.

As shown in FIG. 18, the output screen P7 includes an input field and the like for searching an arbitrary simulation result (work map M1). The output screen P7 includes a write button B71, and when the write button B71 is operated, the work support information D1 (work map M1) is written to the recording medium 5 in a format readable by the work machine 4.

Further, at least a part of the functions of the work map creation system 10 may be realized by a cloud (cloud computing) or the like.

On the contrary, in the first embodiment, the functions of the work map creation system 10 distributed in a plurality of devices may be integrated in one housing. For example, at least a part of the functions distributed to the management server 2 and the user terminal 3 may be integrated in the management server 2 or the user terminal 3.

By the way, as shown in FIG. 19, the result comparison screen P5 may be configured so that the reference map M2 can be changed. The result comparison screen P5 illustrated in FIG. 19 has a map selection button B51 for changing the reference map M2 and a recalculation button B52. This facilitates, for example, changing the reference map M2 from a growth map (NDVI map) to another actual map such as a yield map and recalculating the work map M1.

In addition, the configuration of the work map creation system 10 for realizing the function of collectively creating the work map M1 for two or more fields F1, the function related to the calculation process, and the function related to the restriction process can be adopted independently. Is. Further, the configuration of the work map creation system 10 related to the correction process can also be adopted independently. For example, the creation processing unit 12 does not adopt the function of collectively creating the work map M1 for two or more fields F1, but adopts the function of correcting the work index and recreating the work map M1 according to the correction operation. May be good.

Further, the plurality of sections K of the work map M1 are not limited to the mesh (square) division, and may be set by dividing by an arbitrary figure or the like.

Further, the display unit 33 and the operation unit 34 of the user terminal 3 may have a function as a user interface, and the mode of information output and the mode of information input (operation) are not limited to the above-mentioned modes. .. As an example, the display unit 33 may adopt an aspect such as projection by a projector, audio output, or printing as an aspect of information output. In this case, various screens may be projected by a projector, for example, or may be displayed on a sheet by printing. Further, the operation unit 34 may adopt a mode of inputting information such as voice input, gesture input, or input of an operation signal from another terminal. Further, for the operation unit other than the user terminal 3, a mode such as voice input, gesture input, or input of an operation signal from another terminal may be adopted.

Further, the work support information D1 may be any information that supports the spraying work in the field, and is not limited to the work map M1. The work support information D1 may be information (spraying information) such as a spraying amount (spraying amount per unit area) applied to the entire field F1. That is, since the work map creation system 10 is an example of the work support information creation system, the product may be not limited to the work map M1 but may be work support information D1 in a broad sense. Similarly, the work map M1 generation method is an example of the work support information D1 generation method, and the work map generation program is an example of the work support information generation program.

Further, in the first embodiment, the case where the sprayed product is a fertilizer and the specific component contained in the sprayed product is nitrogen is described as an example, but the specific component is not limited to nitrogen. For example, when the spray is a fertilizer, nitrogen, phosphoric acid, potassium and the like, which are known as the three elements of the fertilizer, can be specific components of the spray. That is, in addition to nitrogen, for example, phosphoric acid or potassium may be used as a specific component. In this case, instead of the nitrogen weight, the amount of phosphoric acid or potassium or the like per unit area of the field F1 is ". It becomes a specific quantity.
