[0003] [Patent Document 1] JP 2019-192138 A Summary of the Invention [Problem to be solved by the invention]

[0004] The display device of Patent Document 1 displays a graphic on a field with a large amount of defective weight on a field map, allowing the user to understand the defective selection content (for example, stink bugs, rot, grasshoppers, etc.) indicated by the graphic. However, the reality is that the user can only check the existence of fields with a large amount of defective weight on the field map and the defective selection content by looking at the display device, but does not know what measures to take regarding the defective selection content. In other words, it is not possible to take specific measures regarding the defective crop content of the field. As a result, it is not possible to improve agricultural work.

[0005] In view of the above-mentioned problems, the present invention has an object to provide an agricultural management system that can take measures against the nature of crop defects in a farm field and improve farm work. [Means for solving the problem]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] [First embodiment] Fig. 1A shows an overall view of the agricultural management system. The agricultural management system 1 is composed of a production management system 2 that manages the agricultural products (crops) from planting to harvesting, a crop management system 3 that manages the agricultural products after harvesting, and a field water management system 4 that manages the water in the field.

[0011] First, an overview of the production management system 2 will be described. For the sake of convenience, the following description will be given assuming that the agricultural products are grains such as rice and wheat. Naturally, the agricultural products are not limited to rice and wheat.

[0012] The production management system 2 is a system that manages various information (called production management information) from grain planting to grain harvesting. Here, the production management information is broadly divided into information on farm work (called work information), information on agricultural crops (grains) (called crop information), and information on the field environment (called environmental information).

[0013] The work information is information including the track record of agricultural work (agricultural track record). For example, if the agricultural work is plowing, the information includes the location of plowing and the date of plowing. If the agricultural work is fertilizing, the information includes the location of fertilization, the date of fertilization, the name of fertilizer, and the amount of fertilizer applied. If the agricultural work is spraying pesticide, the information includes the location of pesticide spraying, the date of pesticide spraying, the name of pesticide, and the amount of pesticide sprayed. If the agricultural work is harvesting, the information includes the location of harvesting and the amount of harvest.

[0014] The work information (agricultural performance) may also include information on the worker who performed the agricultural work (worker's name, number of people involved in the work, etc.) and information on the machine that performed the agricultural work (classification, model, machine identification information, work performance information of the agricultural machine, etc.) The work performance information of the agricultural machine may include, for example, work performance information of the work device 17 (implement) described below, and drive performance information of the three-point link mechanism 16 (lifting and lowering operation, height position, etc.). The work information (agricultural performance) may also include information on the water management device 100 in the field (classification, model, machine identification information of the water management device 100, work performance information of water management, etc.). The work performance information of water management may include water supply date, drainage date, water level, opening control of the water supply unit and drainage unit described below, etc. Note that the work information is not limited to the above content as long as it includes the performance of various agricultural works.

[0015] The crop information is information including grain characteristics, such as the grain variety, grain characteristics (moisture content at harvest, protein content at harvest), and harvest volume. Note that the grain characteristics (moisture content at harvest, protein content at harvest) and harvest volume may be treated as work results. Also, the crop information is not limited to the above content as long as it is information representing agricultural products (grains).

[0016] As shown in FIG. 1A, the production management system 2 has a data collection device 5 capable of collecting production management information (work information, crop information). The data collection device 5 is mounted on agricultural machinery such as a tractor 10, a rice transplanter 10A, a combine harvester 20, and a multicopter 10B. This data collection device 5 is capable of communicating with various devices mounted on the agricultural machinery through an in-vehicle network or the like mounted on the agricultural machinery. This data collection device 5 collects (acquires) various data when the agricultural machinery is operated. In other words, the data collection device 5 collects work information including the agricultural performance of the agricultural machinery from the agricultural machinery that performed the agricultural work.

[0017] Hereinafter, the collection of agricultural performance data by the data collection device 5 will be described using the tractor 10 and the combine harvester 20 as examples. For ease of explanation, the data collection device 5 mounted on the tractor 10 will be referred to as the first data collection device 5A, and the data collection device 5 mounted on the combine harvester 20 will be referred to as the second data collection device 5B.

[0018] First, the configuration of the tractor 10 will be described. FIG. 2 is an overall view of the tractor. As shown in FIG. 1A and FIG. 2, the tractor 10 includes a traveling vehicle (traveling body) 11, an engine 12, a transmission 13, a driver's seat 14, and a control device 15. In addition, various working devices can be detachably connected to the rear of the traveling vehicle 11. In detail, a three-point link mechanism 16 is provided at the rear of the traveling vehicle 11 so as to be capable of ascending and descending, and a PTO shaft for transmitting power from the engine 12 is provided. For example, a fertilizer spreading device, a tilling device, a pesticide spreading device, a seed spreading device, and a harvesting device can be attached to the three-point link mechanism 16 as a working device 17 (implement). FIG. 2 shows an example in which a fertilizer spreading device is attached to the three-point link mechanism 16.

[0019] The control device 15 is a device that performs control of the traveling system and the working system of the tractor 10. For example, the control device 15 controls the operation of the engine 12 as the traveling system control. Furthermore, when the control device 15 receives input from operating tools such as an operating lever and an operating switch provided around the driver's seat 14 as the working system control, the control device 15 controls the lifting and lowering of the three-point linkage mechanism 16, the output (rotation speed) of the PTO shaft, and other operations according to the input value. Note that the control of the traveling system and the working system by the control device 15 is not limited to the above.

[0020] Control signals for controlling the traveling system and the work system, and detection signals detected by various devices mounted on the tractor 10 are output to an in-vehicle network.

[0021] The data collection device 5 (first data collection device 5A) is connected to the control device 15 via an in-vehicle network or the like. When the tractor 10 or the like operates, the first data collection device 5A acquires the control signal and the detection signal output to the in-vehicle network.

[0022] For example, when the rotary tilling device connected to the rear of the tractor 10 is operated (when tilling is performed), the first data collection device 5A acquires data such as the rotary rotation speed, rotary load, engine rotation speed, vehicle speed, tillage depth, etc., via the in-vehicle network. That is, the first data collection device 5A acquires the rotary rotation speed, rotary load, engine rotation speed, vehicle speed, and tillage depth, which are agricultural performance data when tilling is performed as agricultural work.

[0023] In addition, when the fertilizer applicator connected to the rear of the tractor 10 is operated (when fertilization is performed), data such as vehicle speed, engine RPM, and amount of fertilizer applied is acquired through the in-vehicle network. That is, the first data collection device 5A acquires the vehicle speed, engine RPM, and amount of fertilizer applied, which are agricultural results when fertilization is performed as agricultural work. When the fertilizer applicator is connected to the rear of the tractor 10, the tractor 10 functions as a spreader.

[0024] Alternatively, when a pesticide spraying device connected to the rear of the tractor 10 is operated (when pesticide spraying is performed), data such as vehicle speed, engine RPM, and amount of pesticide sprayed is acquired through the in-vehicle network. That is, the first data collection device 5A acquires the vehicle speed, engine RPM, and amount of pesticide sprayed, which are agricultural performance data when pesticide spraying is performed as agricultural work. That is, when the agricultural machine is the tractor 10, the first data collection device 5A collects agricultural performance data of agricultural work performed by the device connected to the tractor 10. When a pesticide spraying device is connected to the rear of the tractor 10, the tractor 10 functions as a sprayer.

[0025] The rice transplanter 10A includes a data collection device 5. The data collection device 5 of the rice transplanter 10A acquires the engine speed, vehicle speed, plant spacing, row spacing, transplanting (direct seeding), and the like, which are agricultural performance data when rice transplanting is performed as agricultural work.

[0026] Instead of the fertilizer or pesticide spraying device of the tractor 10, a multicopter (unmanned aerial vehicle) 10B equipped with a fertilizer or pesticide spraying device may be used. The multicopter 10B functions as a sprayer. The multicopter 10B is equipped with a data collection device 5. The data collection device 5 of the multicopter 10B acquires the flight speed and the amount of fertilizer applied, which are agricultural performance results when fertilization is performed as agricultural work, and acquires the flight speed and the amount of pesticide applied, which are agricultural performance results when pesticide spraying is performed as agricultural work.

[0027] Next, the configuration of the combine harvester 20 will be described. FIG. 3 is an overall view of the combine harvester. As shown in FIG. 3, the combine harvester 20 has a machine body 21, a traveling device 22, a driver's seat 14, an engine 12, a grain tank 24, a reaping device 25, a measuring device 26, a control device 27, and a threshing device (not shown). The traveling device 22 is provided at the bottom of the machine body. The driver's seat 14, the engine 12, the threshing device, and the grain tank 24 are provided in the machine body 21. The reaping device 25 is provided at the front of the machine body 21. The reaping device 25 is a device that harvests grain. The threshing device is a device that threshes the harvested grain. The grain tank 24 is a tank that stores the threshed grain. The control device 27 is a device that controls the engine 12, the threshing device, and the reaping device 25.

[0028] The measuring device 26 is a device that measures the moisture content, protein content, yield, etc. of grains. Specifically, the measuring device 26 has a moisture measuring section 26A that measures the moisture content in grains, a taste measuring section 26B that measures the protein content of grains, and a yield measuring section 26C that measures the yield of grains. The moisture measuring section 26A and the taste measuring section 26B are provided inside the grain tank 24 or around the grain tank 24. The yield measuring section 26C is provided in the lower part of the grain tank 24.

[0029] The taste measuring unit 26B irradiates the grain entering the grain tank 24 with near-infrared light, analyzes the absorption spectrum based on the spectroscopic analysis of the transmitted light, and obtains the amount of components such as protein contained in the grain (protein content), i.e., the protein amount, based on the analysis results. The moisture measuring unit 26A is composed of a sensor that measures the moisture content of the grain using the dielectric constant of the grain, or a sensor that measures the moisture content (moisture content) of the grain using the electrical resistance of the grain. The yield measuring unit 26C is composed of a load cell or the like that measures the weight of the grain tank 24 and converts the weight of the grain tank 24 into the yield. The taste measuring unit 26B, the moisture measuring unit 26A, and the yield measuring unit 26C are not limited to those described above.

[0030] The data collection device 5 (second data collection device 5B) is connected to the control device 27 or the measuring device 26 (moisture measuring section 26A, taste measuring section 26B) and collects the grain harvest yield, moisture content at harvest, and protein content at harvest. In other words, when the agricultural machine is a combine harvester 20, the second data collection device 5B collects the harvest yield as agricultural performance, and collects the moisture content at harvest and protein content at harvest as crop information. As described above, the moisture content at harvest and protein content at harvest may also be treated as agricultural performance.

[0031] As described above, the data collection device 5 can collect agricultural results of agricultural work performed by the equipment connected to the tractor 10, agricultural results of agricultural work performed by the combine harvester 20, agricultural results of agricultural work performed by the rice transplanter 10A, and agricultural results of agricultural work performed by the multicopter 10B. Note that the above-mentioned agricultural results are just an example, and the agricultural results are not limited to the above.

[0032] The data collection device 5 (first data collection device 5A, second data collection device 5B) includes a first storage unit 30 and a first communication unit 31. The first storage unit 30 temporarily stores data including agricultural performance. The first communication unit 31 is configured as a device that performs short-distance or long-distance communication, and can be connected to an external device (computer). For example, the first communication unit 31 is a device that performs wireless communication using Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series, which is a communication standard. The first communication unit 31 may be a device that performs wireless communication using a mobile phone communication network, or a device that performs wireless communication using a data communication network.

[0033] The production management system 2 also includes a computer 33 for managing production management information (work information, crop information). The computer 33 can be broadly divided into a terminal device 33A, which is a worker's computer operated by the farm worker who performs the farm work, a terminal device 33B, which is a manager's computer operated by a manager who manages the farm workers, and an information processing device 33C to which the terminal devices 33A and 33B can be connected.

[0034] The terminal device 33A is a mobile terminal assigned to and carried by an agricultural worker. The terminal device 33B is a personal computer (PC) or the like assigned to an administrator, and is equipped with a display device 33B1. The information processing device 33C is, for example, a server, and is a computer that provides services such as farming support to users and production management of agricultural crops in the field.

[0035] The terminal device 33A is, for example, a smartphone (multi-function mobile phone), a tablet PC, etc. The terminal device 33A includes a second communication unit 35, a second storage unit 36, and a display device 56.

[0036] The second communication unit 35 is configured with a communication device that performs wireless communication with the data collection device 5, the information processing device 33C, etc. The second communication unit 35 is a device that performs wireless communication using, for example, Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series, which is a communication standard. The second communication unit 35 is also a device that performs wireless communication using, for example, a mobile phone communication network, a data communication network, etc.

[0037] Therefore, by connecting the first communication unit 31 of the data collection device 5 and the second communication unit 35 of the terminal device 33A, the terminal device 33A can acquire data such as agricultural performance collected by the data collection device 5, i.e., data including production management information (work information, crop information).

[0038] When acquiring production management information (work information, crop information), the terminal device 33A acquires machine identification information, which is the source of the production management information, in association with the production management information. For example, the terminal device 33A acquires machine identification information for identifying the tractor 10 and the work device 17, machine identification information for identifying the combine harvester 20, machine identification information for identifying the rice transplanter 10A, and machine identification information for identifying the multicopter 10B from the data collection device 5 together with the production management information. Therefore, it is possible to extract the production management information using the machine identification information.

[0039] Furthermore, by connecting the second communication unit 35 of the terminal device 33A and the information processing device 33C, data including agricultural performance, i.e., production management information (work information, crop information), can be transmitted to the information processing device 33C. In addition, various data can be transmitted from the information processing device 33C to the terminal device 33A.

[0040] The terminal device 33A may have a position detection unit 37. The position detection unit 37 is a device that receives signals (position of the GPS satellite, transmission time, correction information, etc.) transmitted from a positioning satellite (for example, a GPS satellite) and detects its own position (for example, latitude, longitude) based on the received signals. For example, if an agricultural worker rides on the tractor 10 to perform agricultural work, the position of the agricultural worker during the agricultural work, i.e., the location during the agricultural work, can be detected.

[0041] More specifically, for example, when tilling is performed by the tractor 10, the place where tilling is performed (field position) can be detected, and when harvesting is performed by the combine 20, the place where harvesting is performed (field position) can be detected. The above-mentioned position detection unit 37 may be provided in agricultural machinery such as the tractor 10, the rice transplanter 10A, the multicopter 10B, and the combine 20.

[0042] The second storage unit 36 ​​stores data (work information, crop information, machine identification information, etc.) transmitted from the data collection device 5, and stores data transmitted from the information processing device 33C.

[0043] Next, the information processing device 33C will be described in detail. The information processing device 33C has a crop plan setting unit 40 that sets a crop plan, and a crop plan storage unit 41 that stores the crop plan. The crop plan setting unit 40 is composed of programs and the like stored in the information processing device 33C. The crop plan is a plan for setting the crops to be planted, the farm fields to be planted, and the like.

[0044] When the terminal device 33B logs in to the information processing device 33C and there is a request from the terminal device 33B to create a crop plan, the crop plan setting unit 40 responds to this request by displaying a screen for creating a crop plan, i.e., a crop plan screen for inputting the crop to be planted and the field to be planted, on the display device 33B1 of the terminal device 33B. In addition, when the crop to be planted and the field to be planted, etc. are input on the crop plan screen, the crop plan setting unit 40 stores the input crop and field as a crop plan in the crop plan storage unit 41.

[0045] Therefore, by connecting the terminal device 33B to the information processing device 33C, a cultivation plan that associates the crops to be planted with the farm field can be easily created, and the created cultivation plan can be stored in the cultivation plan memory unit 41.

[0046] The information processing device 33C also has a work plan creation unit 42 that creates a work plan, and a work plan storage unit 43 that stores the work plan. The work plan creation unit 42 is composed of programs and the like stored in the information processing device 33C. The work plan is a plan that sets a predetermined location (field), agricultural work, the time when the agricultural work will be performed (working time), the agricultural worker who will perform the agricultural work, details of the agricultural work, and the like. The work plan may also include the name of the agricultural crop (type of agricultural crop), etc.

[0047] Examples of agricultural work include making bed soil, filling ridges, plowing, sowing, planting, plowing, cutting furrows, weeding, fertilizing, harvesting, etc. Details of agricultural work include the name of fertilizer and the amount of fertilizer applied if the agricultural work is fertilization, and the name of pesticide and the amount of pesticide applied if the agricultural work is pesticide spraying. Information about machines used to perform the agricultural work may be the details of the agricultural work.

[0048] When the terminal device 33B logs in to the information processing device 33C and there is a request for creating a work plan from the terminal device 33B, the work plan creation unit 42 displays a work plan setting screen for creating a work plan on the display device 33B1 of the terminal device 33B in response to this request. The work plan creation unit 42 displays the work plan setting screen for inputting, for example, the name of the crop, the field, the farm work, the work time, the farm worker, and the details of the farm work. In addition, the work plan creation unit 42 stores the items inputted to the work plan setting screen (the name of the crop, the field, the farm work, the work time, the farm worker, and the details of the farm work) in the work plan storage unit 43 as a work plan. Therefore, by connecting the terminal device 33B to the information processing device 33C, a work plan can be easily created, and the created work plan can be stored in the work plan storage unit 43.

[0049] The information processing device 33C further includes a work instruction unit 44. The work instruction unit 44 is configured from a program or the like stored in the information processing device 33C. The work instruction unit 44 transmits a work plan to the terminal device 33A (a computer for an operator).

[0050] When the terminal device 33A assigned to a farm worker logs in to the information processing device 33C and there is a request from the terminal device 33A to send a work plan, in response to this request the work instruction unit 44 extracts a work plan that includes the worker assigned to the terminal device 33A from the work plan memory unit 43 and sends the work plan to the terminal device 33A.

[0051] As described above, according to the production management system 2, a cultivation plan can be created by the terminal device 33B, and the cultivation plan can be stored in the information processing device 33C. Furthermore, a work plan can be created by the terminal device 33B, and the work plan can be transmitted to the terminal device 33A assigned to the farm worker. The farm worker can carry out farm work while looking at the transmitted work plan. Furthermore, work information and crop information including agricultural performance, i.e., production management information, can be transmitted from the terminal device 33A to the information processing device 33C.

[0052] Next, the transmission of production management information from the terminal device 33A to the information processing device 33C will be described in detail. Fig. 4 is an explanatory diagram of a main screen. As shown in Fig. 4, the display device 56 of the terminal device 33A can display a main screen (first screen) Q1. This main screen Q1 displays a notification button 50 and a collection button 51. The notification button 50 and the collection button 51 are selectable.

[0053] When the notification button 50 is selected, a login process is executed between the terminal device 33A and the information processing device 33C. After logging in, the terminal device 33A requests the information processing device 33C to transmit a work plan. The information processing device 33C transmits a work plan corresponding to the terminal device 33A to the terminal device 33A. The information processing device 33C transmits a work plan including, for example, the crop name, tilling location, tilling date, fertilization location, fertilization date, fertilizer name, fertilizer amount, pesticide spray location, pesticide spray date, pesticide name, pesticide amount, harvest location, worker name, agricultural machinery, etc. to the terminal device 33A.

[0054] When the collection button 51 is selected, the terminal device 33A connects to the data collection device 5 (first data collection device 5A, second data collection device 5B) and acquires work information, etc. including agricultural performance collected by the data collection device 5. The terminal device 33A transmits the acquired work information, etc. to the information processing device 33C. The terminal device 33A transmits, for example, the rotary rotation speed, rotary load, engine rotation speed, vehicle speed, tillage depth, fertilizer amount, pesticide spray amount, harvest amount, moisture amount at harvest, protein amount at harvest, etc. to the information processing device 33C. Note that the notification button 50 and the collection button 51 are separate, but the notification button 50 and the collection button 51 may be combined into one button. When the notification button 50 is selected, the terminal device 33A may also acquire work information, etc. from the data collection device 5.

[0055] FIG. 5 is a diagram showing an example of a display of a work plan. The work plan transmitted from the information processing device 33C is displayed on the work plan screen Q2 of the terminal device 33A as shown in FIG. 5. In addition to the work plan, the terminal device 33A can display a completion button 52 indicating the completion of the farm work. When the completion button 52 is selected, the terminal device 33A converts the work plan shown on the work plan screen Q2 into agricultural performance. Specifically, when the completion button 52 is selected, the terminal device 33A converts items shown in the work plan that cannot be obtained by the data collection device 5 as agricultural performance. For example, when the work plan is "crop name, plowing location, plowing date, fertilization location, fertilization date, fertilizer name, fertilizer amount, pesticide spray location, pesticide spray date, pesticide name, pesticide spray amount, harvest location, worker name, agricultural machine", items other than the fertilizer amount, pesticide spray amount, and harvest amount are converted into agricultural performance. When converting the work plan into the agricultural performance, the predetermined items can be modified by operating the terminal device 33A. The terminal device 33A transmits the converted agricultural performance to the information processing device 33C.

[0056] That is, the terminal device 33A transmits work information (plowing location, plowing date, fertilization location, fertilization date, fertilizer name, fertilizer amount, pesticide spraying location, pesticide spraying date, pesticide name, pesticide spraying amount, harvesting location, worker name, agricultural machinery) to the information processing device 33C. The terminal device 33A also transmits crop information (crop name, harvest yield, moisture content at harvest, protein content at harvest) to the information processing device 33C as agricultural performance. The work information and crop information transmitted from the terminal device 33A are stored for each field in the management information storage unit 47 of the storage device 46 provided in the information processing device 33C.

[0057] Fig. 6 is an explanatory diagram of storing harvested grain in a storage member. When grain is harvested, as shown in Fig. 6, the grain harvested by the combine 20 is placed in a first storage member 55 of a transport vehicle 53 (e.g., a truck). The grain placed in the first storage member 55 is transported by the transport vehicle 53 to a processing facility 60 such as a rice center. The first storage member 55 is a container or the like.

[0058] In the production management system 2, it is possible to set the amount of moisture and protein contained in each grain stored in each first storage member 55. That is, in the crop management system 3, it is possible to associate crop information (crop name, harvest yield, moisture content at harvest, protein content at harvest) with each first storage member 55.

[0059] Next, the association between the crop information and the first storage member 55 will be described. The association between the crop information and the first storage member 55 is performed using the terminal device 33A or the like. This terminal device 33A includes an identification acquisition unit 57 and an association unit 58.

[0060] Fig. 7 is a diagram showing an example of a selection screen. As shown in Fig. 7, the display device 56 of the terminal device 33A can display a machine selection screen Q5 for selecting an agricultural machine such as a combine harvester 20. This machine selection screen Q5 displays a list of combine harvester names corresponding to the owned combine harvester 20. When a specific combine harvester name is selected on the machine selection screen Q5, the terminal device 33A holds machine identification information corresponding to the selected combine harvester name.

[0061] The identification acquisition unit 57 acquires identification information (referred to as storage identification information) for identifying the first storage member 55. The storage identification information is composed of a unique number or the like. This storage identification information is attached to a QR code (registered trademark) affixed to the first storage member 55. The identification acquisition unit 57 is composed of a camera or the like, and retains the storage identification information by reading the QR code (registered trademark) as an image. The association unit 58 associates the machine identification information corresponding to the combine name selected on the machine selection screen Q5 with the storage identification information indicating the first storage member 55 acquired by the identification acquisition unit 57.

[0062] When associating the machine identification information with the storage identification information, the associating unit 58 also associates the harvest management information assigned for management. The harvest management information is an ID code or the like, and is composed of a unique number or the like. For ease of explanation, the ID code used as the harvest management information is referred to as a consignment ID.

[0063] 8, the combine harvester 20 that harvested the grain, i.e., the machine identification information that identifies the combine harvester 20, can be associated with the first storage member 55 that contains the grain harvested by the combine harvester 20, i.e., the storage identification information. The relationship between a specific combine harvester 20 and a specific first storage member 55 can be extracted by the consignment ID.

[0064] Furthermore, the terminal device 33A is capable of associating a specific first storage member 55 with the moisture content and protein content of the grain stored in the first storage member 55. This association is performed using various information. For ease of explanation, the combine 20 selected on the machine selection screen Q5 is referred to as the selected combine, the machine identification information indicating the selected combine is referred to as the selected identification information, the specific first storage member 55 associated with the selected combine is referred to as the determined storage member, and the storage identification information indicating the determined storage member is referred to as the determined identification information.

[0065] The association unit 58 refers to the second storage unit 36 ​​of the terminal device 33A and judges whether or not there is crop information on the grain harvested by the selected combine. For example, if there is crop information corresponding to the selection identification information indicating the selected combine in the second storage unit 36, it is judged that there is crop information on the grain harvested by the selected combine. Here, if there is crop information, the association unit 58 extracts crop information (moisture content at harvest, protein content at harvest) on the grain stored in the determined storage member using items (field, harvest date, work time, worker, machine information, etc.) indicated in the agricultural performance converted from the work plan and time information (year, month, day, hour, minute, etc.) previously held by the terminal device 33A. For example, the association unit 58 extracts, in the second storage unit 36, the agricultural performance having the same harvest date as the day on which the combine 20 and the first storage member 55 were selected on the machine selection screen Q5, and regards the moisture content and protein content corresponding to the extracted agricultural performance as the grain stored in the determined storage member. That is, the association unit 58 associates the extracted crop information, ie, the moisture content and protein content at harvest, with the storage identification information indicating the determined storage member.

[0066] In the above-described embodiment, the determined storage member (storage identification information) and crop information were associated by referring to the second memory unit 36 ​​of the terminal device 33A, but the storage identification information and crop information may also be associated by referring to the management information memory unit 47 of the information processing device 33C.

[0067] For example, the association unit 58 transmits the items (field, harvest date, work time, worker, machine-related information, etc.) indicated in the agricultural performance converted from the work plan and the selection identification information as search keys to the information processing device 33C. Then, the association unit 58 uses the search key to extract crop information harvested by the selected combine from the management information storage unit 47. Then, the association unit 58 associates the crop information extracted from the management information storage unit 47 with the determined storage member (storage identification information).

[0068] 9, the associating unit 58 can associate the storage identification information with the crop information (harvest yield, moisture content at harvest, and protein content at harvest) by searching the second storage unit 36 ​​and the management information storage unit 47. The associated crop information and storage identification information are stored, together with the harvest management information, in the harvest information storage unit 48 of the storage device 46 provided in the information processing device 33C.

[0069] In addition to associating the crop information with a predetermined first storage member 55, work information (agricultural performance) may also be associated with the crop information. For example, the terminal device 33A is connected to the information processing device 33C, and agricultural performance (e.g., the harvested field, the worker's name, etc.) corresponding to the crop information is extracted from the management information storage unit 47, and the extracted agricultural performance (work information), crop information, storage identification information, and consignment ID are associated with each other and stored in the harvest information storage unit 48, as shown in Fig. 10. Also, the association between storage identification information and crop information is not limited to the above-mentioned method.

[0070] As described above, the production management system 2 can collectively manage, for example, crop planting plans, farm work plans, farm work results (work information), information on crop harvest (crop information), and the like.

[0071] Next, a description will be given of the crop management system 3. The crop management system 3 is a system that mainly manages post-harvest agricultural crops (grains). Specifically, the crop management system 3 is a system that manages processing equipment 60 that processes post-harvest agricultural crops (grains).

[0072] First, a description will be given of the processing equipment 60. As shown in Fig. 11, the processing equipment 60 has a dryer 61, a cooling tank 62, a rice huller 63, a preparer 64, and a weighing device 65.

[0073] The dryer 61 is a device that dries grain. The dryer 61 has an inlet 61A for inputting grain (paddy), a storage section 61B for temporarily storing grain, a drying section 61C for receiving the grain stored in the storage section 61B and drying the supplied grain, a circulation section 61D, and a control section (referred to as a first controller) 66A. The circulation section 61D is a mechanism for transporting grain inputted into the inlet 61A to the storage section 61B and returning grain dried in the drying section 61C to the storage section 61B.

[0074] The first controller 66A is a device that controls the dryer 61, and controls the drying temperature of the drying section 61C and the circulation speed of the circulation section 61D, etc., so that the moisture content and protein content of the grain after drying are set to predetermined target values.

[0075] Furthermore, the first controller 66A can output operation information (referred to as drying operation information) of the dryer 61. For example, the first controller 66A outputs, as the drying operation information, an operation state (loading, drying, stopped, etc.), a drying start time, a drying end time, a moisture content during drying (drying moisture content), a drying temperature, a weight of grains during drying (dry weight), etc.

[0076] Therefore, according to the dryer 61, the grain put into the inlet 61A (loaded) can be temporarily stored in the storage section 61B while being supplied to the drying section 61C, where it can be dried. Also, by returning the grain dried in the drying section 61C to the storage section 61B, the grain can be dried while being circulated.

[0077] The cooling tank 62 is a tank in which the grains dried in the dryer 61 are stored for a predetermined period of time to be cooled. The huller 63 is a device that hulls the grains cooled in the cooling tank 62.

[0078] The preparation machine 64 is a device that prepares grains (such as coarse brown rice) obtained by hulling the grains in the huller 63. In other words, the preparation machine 64 is a device that can prepare grains after drying in the dryer 61. The preparation machine 64 is a device that performs color inspection and color sorting, and has a color sorter 67 that sorts grains by color.

[0079] The color sorter 67 has a first hopper 67A, an imaging unit 67B, an injector 67C, and a control unit (second controller) 66B. The first hopper 67A is a member that puts grains in and drops the grains. The imaging unit 67B is a device that captures images of the grains as they fall, and the injector 67C separates grains that are determined to be defective based on the color sorting results.

[0080] The second controller 66B is a device that controls the color sorter 67, and for example, judges whether the color of the grain is defective from the image of the grain captured by the imaging unit 67B. That is, the second controller 66B detects damaged grains (such as stink bugs), white immature grains (white rice), dead rice, and discolored grains (scorched grains) based on the color of the captured image of the grain, and judges the grains that fall under these categories to be defective. If the second controller 66B judges the grains to be defective, it outputs a command to the injector 67C to blow away the defective grains.

[0081] In addition, the second controller 66B can output operation information (referred to as preparation operation information) of the color selector 67. For example, the second controller 66B outputs, as the preparation operation information, color selection results (color conditions, good rate, bad rate), color start time, color end time, etc.

[0082] Therefore, according to the color sorter 67, by placing grains in the first hopper 67A, the grains are imaged, and based on the captured image, the grains are color-sorted, and defective grains are separated from good grains.

[0083] The proportion of defective grains is determined by providing a broken rice weighing device that weighs the weight (discharge weight) of grains that have been determined to be defective after color sorting. The proportion of defective grains can then be determined, for example, by dividing the weight of grains fed into the color sorter 67 (feed weight) by the discharge weight. The proportion of good grains (yield) can then be determined from the proportion of defective grains. Note that the method of determining the yield is not limited to this. The proportion of good grains and the proportion of defective grains may also be determined by the operation management unit 74, which will be described later. In this case, it is desirable to use the size-reduced equivalent amount, which will be described later, as the feed weight.

[0084] The weighing device 65 weighs the grain after it has been processed by the color sorter 67 etc., and has a second hopper 65A for containing the grain, a base 65B provided at the bottom of the second hopper 65A, a weighing section 65C, and a control section (fourth controller) 66D.

[0085] The second hopper 65A is a container for holding grain, and the base 65B is a platform for placing a second storage member 69 for holding the grain. The second storage member 69 is a flexible container bag or a container, etc. The weighing unit 65C is a device for measuring the weight of the grain placed in the second storage member 69.

[0086] The fourth controller 66D is a device that controls the weighing device 65, and performs processes related to the weighing result, weighing start, weighing end, etc. The fourth controller 66D can also output operation information (weighing operation information) of the weighing device 65. For example, the fourth controller 66D outputs the measurement result (e.g., shipping amount, number of bags, bagged amount), weighing start time, weighing end time, etc. as the weighing operation information.

[0087] As shown in Figs. 1A and 11, the crop management system 3 includes a crop management computer 70 configured with a server and the like. The crop management computer 70, the first controller 66A, the second controller 66B, the third controller 66C, and the fourth controller 66D are connected to one another via a network such as a LAN. This network allows data to be transmitted and received between the crop management computer 70 and each controller. For example, the crop management computer 70 stores operation information output from each controller and outputs various data to each controller. In addition, the crop management computer 70 is connectable to an information processing device 33C via an external network.

[0088] The crop management computer 70 has a production information acquisition unit 71, an operation acquisition unit 72, an information output unit 73, and an operation management unit 74.

[0089] The production information acquisition unit 71 acquires data stored in the information processing device 33C. For example, when a specific grain is dried by the dryer 61, the production information acquisition unit 71 accesses the information processing device 33C and refers to the harvest information storage unit 54. Then, the production information acquisition unit 71 acquires the storage identification information of the first storage member 55, the crop information associated with the storage identification information, and the consignment ID. In addition to the crop information, the production information acquisition unit 71 acquires information including agricultural performance (such as the name of the crop plan and the field).

[0090] The operation acquisition unit 72 is composed of electronic components, programs, and the like, and acquires various pieces of operation information from the first controller 66A, the second controller 66B, the third controller 66C, and the fourth controller 66D.

[0091] The information output unit 73 is composed of electronic components, programs, and the like, and outputs various information to the first controller 66A, the second controller 66B, the third controller 66C, and the fourth controller 66D.

[0092] The operation management unit 74 performs processing related to the processing equipment 60. As shown in FIG. 12, the operation management unit displays a management screen Q8 on a display device connected to the crop management computer 70. This management screen Q8 is a screen that displays information related to the operation of the processing equipment 60. The management screen Q8 has a goods receipt display section 75A, a drying display section 75B, a cooling display section 75C, a preparation display section 75D, and a measuring device display section 75E. The operation management unit 74 controls the display of the goods receipt display section 75A, the drying display section 75B, the cooling display section 75C, the preparation display section 75D, and the measuring device display section 75E.

[0093] The goods receipt display section 75A displays the storage identification information and crop information acquired by the production information acquisition section 71. Specifically, the drying display section 75B displays the name of the first storage member corresponding to the storage identification information and crop information for the grains stored in the first storage member. The goods receipt display section 75A can also display information including agricultural performance acquired by the production information acquisition section 71.

[0094] 12, the container name, which is the name of the first storage member 55, the name of the crop plan, the yield, the moisture content (the moisture content at harvest), the protein content (the protein content at harvest), the field, and the recommended placement destination are displayed on the goods receipt display section 75A. The container name, the name of the crop plan, the yield, the moisture content, the protein content, and the field are information obtained by the production information acquisition section 71 from the information processing device 33C.

[0095] The operation management unit 74 determines a recommended storage location based on the drying operation information obtained from the first controller 66A, and displays the storage location on the goods receipt display unit 75A. For example, assume that of the four dryers, the third dryer (referred to as No. 3) is stopped and the fourth dryer (referred to as No. 4) is being stored. In this case, the operation management unit 74 recognizes that No. 3 is stopped and No. 4 is being stored based on the drying operation information.

[0096] Since the protein content of the grain loaded into Unit 3 is 7.2%, and Container 01, Container 03, Container 04, and Container 07 contain grains with approximately the same protein content as the grain loaded into Unit 3, operation management unit 74 recommends Unit 3 as the loading destination for Container 01, Container 03, Container 04, and Container 07. Then, operation management unit 74 displays Unit 3, the recommended destination, in the loading destination column for Container 01, Container 03, Container 04, and Container 07 on the cargo receiving display unit 75A.

[0097] Furthermore, because the protein content of the grain loaded into Unit 4 is 6.3%, the operation management unit 74 recommends that Unit 4 be loaded into containers 02 and 05, which contain grains with this protein. The operation management unit 74 then displays Unit 4, which is the recommended loading destination, in the loading destination column for containers 02 and 05 on the cargo receiving display unit 75A. However, since Unit 1 is drying and Unit 2 is waiting to be discharged, the operation management unit 74 does not recommend loading into Unit 4.

[0098] Therefore, a recommended dryer 61 is determined based on protein content, so that grains with relatively similar protein content can be loaded into the dryer.

[0099] As shown in Fig. 12, a decision button 78 for deciding to stake out the container is displayed in the stake-out destination of the goods receipt display section 75A. When this decision button 78 is selected, the operation management section 74 decides that the container corresponding to the decision button 78 will be staked out to the recommended destination, and sets the harvest amount of the container to the "stacking amount", the moisture amount at the time of harvest to the "moisture amount at stake-out (stacking moisture amount)", and the protein amount at the time of harvest to the "protein amount at stake-out (stacking protein amount)".

[0100] The operation management unit 74 calculates the total loading amount, loading moisture amount, and loading protein amount at the time of stoppage and during loading based on the set loading amount, set loading moisture amount, set loading protein amount, and the loading amount, loading moisture amount, and loading protein amount already in the dryer 61.

[0101] The information output unit 73 outputs the total amount of loading, the amount of loading moisture and protein, the dryer number, and the container name (container identification information) to the first controller 66A. The first controller 66A displays the total amount of loading, the amount of loading moisture and protein, the dryer number, and the container name on a display device provided in the dryer 61.

[0102] The drying display section 75B displays the status of the dryer 61, etc. Specifically, the drying display section 75B displays the status of the dryer 61, such as the dryer number, the cropping plan, the operation status (loading, drying, stopped, etc.), the remaining capacity (loadable amount) that is the capacity that can be loaded into the dryer 61, the total loading amount, the moisture amount (loaded moisture amount, dried moisture amount), the protein amount (loaded protein amount, dried protein amount), and the discharge destination. The operation status and the dried moisture amount are drying operation information obtained by the operation acquisition section 72 from the first controller 66A. The cropping plan is information obtained by the production information acquisition section 71. The total loading amount, the remaining capacity, and the discharge destination are information shown based on the calculation result by the operation management section 74. In this embodiment, the loaded protein amount is treated as the protein amount (dried protein amount) of the grain being dried.

[0103] The calculation of the remaining capacity by the operation management unit 74 will be described. The operation management unit 74 calculates the remaining capacity by subtracting the total loading amount from the maximum loading amount of the dryer 61 corresponding to the dryer number. The maximum loading amount of each dryer 61 is pre-stored in the crop management computer 70. The operation management unit 74 also displays the vertical axis of the grag in the area displaying the remaining capacity on the drying display unit 75B. The operation management unit 74 then displays the maximum loading amount of the dryer 61 corresponding to the dryer number at the top of the vertical axis, displays zero at the bottom of the vertical axis, and displays the remaining capacity along the vertical axis.

[0104] Therefore, the operation management unit 74 can determine the amount of grain that can be loaded into the dryer (remaining amount) based on the harvested amount of grain, the amount to be loaded into the dryer, and the maximum loading amount of the dryer. Since the possible loading amount and the maximum loading amount are displayed, the worker can easily determine whether or not grain can be loaded into the dryer. In particular, when there are multiple dryers 61, the order in which to load grain can be appropriately determined by looking at the possible loading amount.

[0105] The operation management unit 74 determines the discharge destination of the cold-discharging tank 62 based on the protein amount of the grain stored in the cold-discharging tank 62, and displays the discharge destination on the drying display unit 75B. For example, assume that there are four cold-discharging tanks 62. Here, if the protein amount (cold-discharging protein amount) of the grain stored in the second cold-discharging tank 62 is 7.3% and the protein amount (dried protein amount) of the grain stored in the second dryer 61 is 7.3%, the operation management unit 74 determines the second cold-discharging tank 62 as the discharge destination since the cold-discharging protein amount and the dried protein amount are the same. The protein of the grain stored in the cold-discharging tank 62 is determined based on the crop information discharged from the dryer 61 to the cold-discharging tank 62.

[0106] In addition, a decision button 78 for deciding the discharge destination is displayed in the discharge destination of the drying display unit 75B. When this decision button 78 is selected, the operation management unit 74 determines that the grain has been discharged from the dryer 61 corresponding to the decision button 78 to the discharge destination cooling tank 62. Then, the operation management unit 74 calculates the weight of the grain after drying (the discharge amount discharged to the cooling tank 62), i.e., the drying equivalent amount, based on the total charged amount, the charged moisture amount, and the dried moisture amount. For example, the drying equivalent amount is calculated by "drying equivalent amount (kg) = total charged amount (kg) - (charged moisture amount [%] - dried moisture amount at end of drying [%]) x total charged amount [kg]".

[0107] Therefore, the weight (converted amount) of the grain after drying can be calculated based on the charged moisture content and the dried moisture content (moisture content after drying). That is, the grain to be put into the cooling tank 62 can be grasped without providing a weight scale or the like on the inlet side of the cooling tank 62. Moreover, the amount of grain to be put into the huller 63 and the amount to be put into the preparation machine 64 can be calculated using the converted amount.

[0108] In addition, the operation management unit 74 regards the moisture content at the end of drying (drying moisture content) as the moisture content of the grain placed in the cooling tank 62 (cooling moisture content), and regards the protein content at the end of drying as the protein content of the grain placed in the cooling tank 62 (cooling protein content).

[0109] The cooling display section 75C displays the status of the cooling tank 62. Specifically, the cooling display section 75C displays drying management information, crop plan, dry equivalent amount, cooling moisture amount, cooling protein amount, etc. as the status of the cooling tank 62. The cooling display section 75C also displays the discharge destination.

[0110] The preparation display unit 75D displays the status of the preparation machine 64, etc. Specifically, the preparation display unit 75D displays drying management information, crop plan, refined grain equivalent amount, color sorter number, operation status (color selecting, stopped, etc.), and color selection result as the status of the preparation machine 64. The color sorter number, operation status, and color selection result are preparation operation information obtained by the operation acquisition unit 72 from the second controller 66B. The preparation display unit 75D also displays the discharge destination. The drying equivalent amount is information calculated by the operation management unit 74.

[0111] The operation management unit 74 calculates the amount of polished rice that can be fed into the color sorter 67 based on the dry equivalent amount. The operation management unit 74 calculates the amount of polished rice that can be fed into the color sorter 67, for example, by "polished rice equivalent amount (kg) = dry equivalent amount (kg) x weight of rice husk relative to weight of coarse brown rice (husk removal rate) (%)". Since the weight of rice husk is about 15% of the weight of coarse brown rice, the husk removal rate is set to 0.85. Note that the husk removal rate is not limited to the value mentioned above.

[0112] Therefore, the weight (equivalent amount of refined grain) of the grain that can be fed into the preparation machine 64 to be prepared after processing by the rice huller 63 can be known in advance. In other words, the grain to be fed into the preparation machine 64 can be known without providing a weight scale or the like on the inlet side of the preparation machine 64.

[0113] The measuring device display unit 75E displays the status of the measuring device 65, etc. The measuring device display unit 75E displays drying management information, crop planning, total bagging amount, shipping results (shipping amount, bagging number, bagging amount), etc. as the status of the measuring device 65. The shipping results (shipping amount, bagging number, bagging amount) are measuring operation information that the operation acquisition unit 72 has obtained from the fourth controller 66D.

[0114] As described above, the crop management computer 70 can manage the operation of the processing equipment 60 using operation information obtained from each controller (drying operation information, preparation operation information, weighing operation information) and information obtained from the information processing device 33C (harvest yield, moisture content at harvest, protein content at harvest, crop plan).

[0115] In the processing equipment 60, when each process is performed, management information is assigned corresponding to each process. Specifically, in the drying process in the dryer 61, management information (drying management information) is assigned for each operation of the dryer 61. In addition, in the preparation process in the preparer 64, management information (preparation management information) is assigned for each operation of the preparer 64, and in the weighing process in the measuring device 65, management information (measurement management information) is assigned for each operation of the measuring device 65.

[0116] The drying management information, preparation management information, and measurement management information are represented by, for example, a lot number or ID. The drying management information, preparation management information, and measurement management information are assigned by the crop management computer 70, and the lot number or ID assigned to each controller is output.

[0117] The crop management computer 70 has an association unit 80. The association unit 80 associates operation information obtained from each controller, the results of calculations performed by the operation management unit 74, or information obtained by the production information acquisition unit 71. The association unit 80 is composed of electronic components, programs, and the like.

[0118] As shown in FIG. 13, the associating unit 80 associates drying information, such as drying operation information (dried moisture content, dried protein content, drying start time, drying end time, dried weight) obtained from the first controller 66A, the results calculated by the operation management unit 74 (charged moisture content, charged protein content), and information obtained by the production information acquisition unit 71 (crop plan), with drying management information. In detail, the crop management computer 70 automatically issues a lot number as drying management information before starting the operation of the dryer 61. Then, for example, when the number of the dryer is decided by the decision button 78 of the goods receipt display unit 75A and it is obtained from the first controller 66A that the dryer 61 corresponding to the number has started operation, the associating unit 80 determines the association between the issued lot number and the drying information of the dryer 61 that has decided to perform drying.

[0119] After the dryer 61 starts drying, the drying information obtained until the end of drying continues to be linked and associated with the lot number. When the operation of the dryer 61 ends, the associated drying information and drying management information are stored in an information storage unit 81 provided in the crop management computer 70. The associated drying information and drying management information are transmitted from the crop management computer 70 to the first controller 66A and displayed on the display device of the dryer 61.

[0120] Therefore, since the drying control information is associated with the drying information including the drying operation information, the operation of the dryer 61 can be managed for each operation unit (each lot number) of the drying control information. For example, the dried moisture content, dried protein content, drying start time, drying end time, and dried weight can be grasped for each operation unit, and these can be reflected in the preparer 64 and weighing device 65 located downstream.

[0121] In addition, as shown in FIG. 14, the association unit 80 associates preparation information regarding the preparation machine 64, such as preparation operation information (operation status, color selection result, color selection start time, color selection end time) obtained from the second controller 66B and results calculated by the operation management unit 74 (dry equivalent amount), with preparation management information.

[0122] In detail, the crop management computer 70 automatically issues a lot number as preparation management information before the preparation machine 64 (color selector 67) starts to operate. For example, when the number of the color selector is determined by the decision button 78 shown on the cooling display unit 75C and it is obtained from the second controller 66B that the color selector 67 corresponding to the number has started to operate, the association unit 80 determines the association between the issued lot number and the preparation information of the color selector 67 that determined the color selection. Then, after the color selection by the color selector 67 starts, the association and association between the preparation information obtained by the end of the color selection and the lot number are continued. When the operation of the color selector 67 ends, the associated preparation information and preparation management information are stored in the information storage unit 81. The associated preparation information and preparation management information are transmitted from the crop management computer 70 to the second controller 66B and displayed on the display device of the preparation machine 64 (color selector 67).

[0123] Therefore, since the preparation management information is associated with the preparation information including the preparation operation information, the operation of the preparation machine 64 can be managed in operation units of the preparation management information. For example, the operation state, color selection result, color selection start time, color selection end time, etc. can be grasped in operation units, and these can be reflected in the measuring device 65 located downstream or fed back to the dryer 61 located upstream.

[0124] Furthermore, as shown in FIG. 15, the associating unit 80 associates the weighing operation information (shipping amount, number of bags, bagged amount, weighing start time, weighing end time) obtained from the fourth controller 66D with the weighing management information.

[0125] In detail, the crop management computer 70 automatically issues a lot number as preparation management information before the weighing device 65 starts to operate. Then, for example, after the decision button 78 shown on the weighing device display unit 75E is selected, the crop management computer 70 acquires operation information from the third controller 66C that the operation has started, and the association unit 80 determines the association between the issued lot number and the measurement information. Then, after the weighing device starts to measure, the association and association between the measurement information obtained until the end of the measurement and the lot number are continued. When the operation of the weighing device 65 ends, the associated measurement information and measurement management information are stored in the information storage unit 81. The associated preparation information and preparation management information are transmitted from the crop management computer 70 to the fourth controller 66D and displayed on the display device of the weighing device 65.

[0126] Therefore, since the measurement management information is associated with the preparation information including the measurement operation information, the operation of the measuring device 65 can be managed in operation units of the measurement management information. For example, the shipping amount, the number of bags, the bagging amount, the measurement start time, and the measurement end time can be grasped, and these can be fed back to the preparation machine 64 located upstream and the dryer 61 located upstream, etc.

[0127] In the processing facility 60, grains are processed in the order of the dryer 61, the preparer 64 (e.g., color sorter 67), and the weighing machine 65. Here, when a downstream device performs processing, the associating unit 80 associates the downstream management information with the upstream management information of the upstream device. When the preparer 64 prepares grains that have been dried in the dryer 61 corresponding to the drying management information, the associating unit 80 associates the drying management information, which is one piece of upstream management information, with the preparation management information, which is one piece of downstream management information.

[0128] As shown in FIG. 16, in detail, the crop management computer 70 associates a lot number issued before the start of drying in the dryer 61 with the lot number of the dryer 61 that dried the grain fed into the color selector 67 (a lot number determined for each operation of the dryer 61). As described above, after a predetermined drying is completed, the cooling tank 62 and the color selector 67 can be selected as the discharge destination by pressing the decision button 78, so that the lot number determined for each operation of the dryer 61 can be easily associated with the lot number determined for each operation of the color selector 67. The associated drying management information and preparation management information are then stored in the information storage unit 81. The associated drying management information and preparation management information can be displayed on the display device of the crop management computer 70.

[0129] Therefore, before preparation, drying information when the grain to be fed into the preparation machine 64 is dried can be obtained using the drying control information as a search key, so that it is possible to set the settings of the preparation machine 64 taking into account the operation history of the dryer 61. Furthermore, when preparation is performed by the preparation machine 64, it is possible to check how the dryer 61 has operated on an operation basis. The associating unit 80 may associate the drying control information, which is one of the upstream management information, with the weighing control information, which is one of the downstream management information, when the grain that has been dried by operation of the dryer 61 corresponding to the drying control information is weighed by the weighing device 65.

[0130] Specifically, the crop management computer 70 associates a lot number issued before the start of drying in the dryer 61 with the lot number of the dryer 61 that dried the grain fed into the weighing machine 65 (a lot number determined for each operation of the dryer 61). As described above, after a predetermined drying is completed, the cooling tank 62, the color sorter 67, and the weighing machine 65 can be selected as the discharge destination by pressing the decision button 78, so that the lot number determined for each operation of the dryer 61 can be easily associated with the lot number determined for each operation of the weighing machine 65. The associated drying management information and weighing management information are then stored in the information storage unit 81. The associated drying management information and weighing management information can be displayed on the display device of the crop management computer 70.

[0131] For example, the weighing device 65 may weigh and ship in units of 30 kg, and the dryer 61 may dry several tons (e.g., 6 tons). Therefore, for one lot of the dryer 61, the weighing device 65 may handle 200 lots. In the present invention, since the drying management information and the weighing management information are associated with each other, the correspondence can be understood even if the processing unit (number of lots) differs for each process. In other words, when weighing is performed with the weighing device 65, it is possible to check how the dryer 61 has been operating for each operation unit.

[0132] In addition, when the weighing device 65 weighs the grain prepared by the preparation device 64 corresponding to the preparation management information, the association unit 80 may associate the preparation management information, which is one of the upstream management information, with the weighing management information, which is one of the downstream management information. In detail, the crop management computer 70 associates the lot number issued before weighing by the weighing device 65 with the lot number (lot number determined for each operation of the color selector 67) in the color selector 67 that color-selected the grain to be fed into the weighing device 65. As described above, after the completion of a predetermined color selection, the weighing device 65, which is the discharge destination of the grain from the color selector 67, can be selected by the decision button 78, so that the lot number determined for each operation of the weighing device 65 can be easily associated with the lot number determined for each operation of the color selector 67. The associated preparation management information and weighing management information are stored in the information storage unit 81. The associated preparation management information and weighing management information can be displayed on the display device of the crop management computer 70.

[0133] Therefore, when measuring with the measuring device 65, it is possible to check how the preparation machine 64 is operating on an operation basis.

[0134] As described above, while the information processing device 33C manages production management information (work information, crop information), the crop management computer 70 can manage information related to processing in the processing facility 60, and by linking these, the production management information, particularly the crop information, can be used to perform processing in the processing facility 60. In the processing facility 60, information on at least the dryer 61, preparer 64, and weighing device 65 can be shared with each other, and information on the operation of each process can be reflected in the other processes.

[0135] Furthermore, the associating unit 80 associates various information of each process in the processing equipment 60, and also associates production management information obtained from the information processing device 33C with various information of each process. Specifically, the associating unit 80 associates production management information (work information, crop information) with management information assigned to each operation (drying management information, preparation management information, measurement management information).

[0136] The process of associating the drying management information, drying information, work information, and crop information will be described. As described above, when the dryer number is determined by the decision button 78 of the consignment display section 75A, the association section 80 holds the harvest management information (consignment ID) associated with the first storage member 55 corresponding to the decision button 78 and the crop information of the grain contained in the first storage member 55.

[0137] Then, when the drying management information (lot number) and the drying information are linked, the associating unit 80 associates the harvest management information (receiving ID) that has been stored in advance with the drying management information (lot number) and the drying information.

[0138] The associating unit 80 also connects to the harvest information storage unit 48, and uses the stored harvest management information (receiving ID) as a search key to extract work information and crop information including agricultural results associated with the receiving ID. Then, as shown in FIG. 17, the associating unit 80 associates the extracted work information, crop information, and harvest management information (receiving ID) including agricultural results with the drying management information and drying information. Then, the associated drying management information, drying information, work information, crop information, and harvest management information are stored in the information storage unit 81. The associating unit 80 may associate the harvest management information with the drying management information, and store only this association in the information storage unit 81.

[0139] Therefore, since the drying operation information, work information, and crop information are associated with each operation of the dryer 61, it is possible to compare the results of drying by the dryer 61, the results of farm work, and the state of the crop at the time of harvest. For example, it is possible to grasp the dried moisture content and dried protein content in relation to the moisture content and protein content at the time of harvest in the field and at harvest.

[0140] The work information associated by the associating unit 80 may be any of the following: tilling location, tilling date, fertilization location, fertilization date, fertilizer name, fertilizer amount, pesticide spray location, pesticide spray date, pesticide name, pesticide amount, harvest location, worker name, agricultural machinery, or other information. It is desirable that the work information includes at least the harvest location. Furthermore, the crop information associated by the associating unit 80 may be any of the following: crop name, harvest yield, moisture content at harvest, protein content at harvest, or other information.

[0141] The associating unit 80 also associates the preparation information, preparation management information, work information, and crop information, as shown in Fig. 17. For example, when associating the drying management information with the preparation management information, the associating unit 80 takes over the work information and crop information that have been previously associated with the drying management information, and associates the taken-over work information and crop information with the preparation management information as well. The associated preparation information, preparation management information, work information, and crop information are then stored in the information storage unit 81.

[0142] Therefore, since preparation operation information, work information, and crop information are associated with each operation of the preparation machine 64, it is possible to compare the results of color selection by the preparation machine 64, the results of farm work, and the state of the crop at the time of harvest. For example, it is possible to grasp the color selection results (proportion of good products, proportion of defective products) for the field, amount of fertilizer applied, and amount of pesticide sprayed.

[0143] The associating unit 80 also associates the measurement information, measurement management information, work information, and crop information. For example, when associating the drying management information with the measurement management information, the associating unit 80 takes over the work information and crop information that have been previously associated with the drying management information, and associates the taken-over work information and crop information with the measurement management information. The associated measurement information, measurement management information, work information, and crop information are then stored in the information storage unit 81.

[0144] Therefore, since the weighing operation information, work information, and crop information are associated with each operation of the weighing device 65, it is possible to compare the results of weighing with the weighing device 65, the results of farm work, and the state of the crop at the time of harvest. For example, it is possible to grasp the weighing results (shipping amount, bagged number, bagged amount) for the field, the amount of fertilizer applied, and the amount of pesticide sprayed.

[0145] In the above-mentioned agricultural management system 1, various information on each process of the processing equipment 60 can be associated with the production management information obtained from the information processing device 33C, so that agricultural production can be reviewed and improved by comparing the two. That is, it is possible to trace back to the farm work when the crop was cultivated and the state of the crop at the time of harvest. In addition, the processing equipment can be set up, etc., by referring to the work information and crop information obtained when the processing equipment 60 is in operation. For each operation of the processing equipment, it is possible to trace back to the farm work when the crop was cultivated and the state of the crop at the time of harvest.

[0146] Next, the field water management system 4 will be described. As shown in Fig. 1A, the field water management system 4 includes a water management device 100 provided in the field, and a support device 201 that supports the water management device 100. For example, in the case of a user who owns multiple fields, a water management device 100 on the water supply side and a water drainage side are provided for each of the multiple fields, and it is also possible to control the multiple water management devices 100 with a single support device 201.

[0147] First, the water management device 100 installed in the field H1 will be described with reference to Fig. 18A. As shown in Fig. 18A, a pipeline 110 through which irrigation water flows is installed at a predetermined location around the field H1 where agricultural products (crops) are cultivated. The water management device 100 is connected to the pipeline 110.

[0148] Specifically, the pipeline 110 includes a supply pipe 110a and a branch pipe 110b that branches off from the supply pipe 110a and extends toward the farm field H1. The supply pipe 110a is connected to an irrigation channel, through which irrigation water from the irrigation channel flows. The branch pipe 101b is connected to the water management device 100. Therefore, the irrigation water from the supply pipe 110a is supplied to the water management device 100 through the branch pipe 101b.

[0149] It is also possible to provide a water management device 100 for each of the multiple farm fields H1. In this case, multiple branch pipes 101b are provided at predetermined intervals along the length of the supply pipe 110a, and the multiple branch pipes 101b are connected to the water management devices 100 in each of the farm fields H1. In other words, the multiple branch pipes 101b are connected to the multiple water management devices 100 in a one-to-one relationship.

[0150] <Overview of the water management device 100 on the water supply side of the field H1> As shown in Fig. 18A, the water management device 100 on the water supply side of the field H1 is the first water management device 100A. The first water management device 100A (water management device 100) is equipped with a water supply unit 105 that supplies water to the field H1. The water supply unit 105 is a mechanism (adjustment mechanism) that adjusts the water supply from the branch pipe 101b to the field H1. Specifically, the water supply unit 105 is equipped with a cylindrical main body 101 to which the branch pipe 101b is connected and through which the water can pass, a valve body 102 (actuator) that can be opened and closed provided inside the main body 101, and a supply port 103 that penetrates the main body 101 in the thickness direction and through which the water flows toward the field H1.

[0151] The opening of the valve element 102 is changed by a control device 160, which will be described later. When the opening of the valve element 102 is zero (closed state), water is not supplied to the field H1. On the other hand, when the opening of the valve element 102 is not zero (open state), irrigation water is supplied to the field H1 at a flow rate according to the opening. Note that the water supply unit 105 is not limited to the configuration described above.

[0152] <Outline of the water management device 100 on the drainage (falling water) side of the field H1> As shown in FIG. 18A, the water management apparatus 100 is provided on the water supply side of the field H1, but a further water management apparatus 100 may be provided on the drainage side (falling water side) where water (irrigation water) supplied to the field H1 is discharged. The water management apparatus 100 on the drainage side of the field H1 is the second water management apparatus 100B. The second water management apparatus 100B (water management apparatus 100) is equipped with a drainage section 106 that drains the field H1. The drainage section 106 is a mechanism (adjustment mechanism) that adjusts drainage from the field H1 to the drainage channel 120.

[0153] One end of a drain pipe 121 is connected to the drainage channel 120, and the other end of the drain pipe 121 is connected to a drainage basin 122. A water fall section 123 is provided in the drainage basin 122, and a water management device 100 (second water management device 100B) on the drainage (falling water) side is connected to the upper part of the water fall section 123.

[0154] 18A, the drainage section 106 is provided on the water fall section 123 side of the second water management device 100B. The drainage section 106 includes a partition section 125 (actuator) that can be moved vertically to change its position between a state in which water is not allowed to fall (closed state) and a state in which water is allowed to fall (open state), and a movement mechanism 126 that moves the partition section 125 vertically.

[0155] The height of the partition 125 is changed by vertical movement by the moving mechanism 126. The partition 125 is cylindrical, and is in a closed state that does not allow water to drain when the upper end of the partition 125 is higher than the water level of the field H1, and is in an open state that allows water to drain when the upper end is lower than the water level of the field H1. The drainage unit 106 is not limited to the above-mentioned configuration.

[0156] <Water management equipment 100> Fig. 1B is a detailed diagram of a water management system for a farm field. As shown in Fig. 1B, the water management device 100 includes a solar panel 140 and a power storage device 141. The solar panel 140 is a power generation device that converts solar light energy into electrical energy. The power storage device 141 stores the power generated by the solar panel 140. The water management device 100 can be operated by the power stored in the power storage device 141.

[0157] The water management device 100 includes a detection device 150, a control device 160, and a communication device 170. The detection device 150 is a sensor that detects the state (environment) of the field H1, and includes a water level sensor 50a that detects the water level, a water temperature sensor 50b that detects the water temperature, an air temperature sensor 50c that detects the air temperature, a humidity sensor 50d that detects the humidity, and a soil temperature sensor 50e that detects the soil temperature. Note that the water management device 100 does not need to include all of the water level sensor 50a, the water temperature sensor 50b, the air temperature sensor 50c, the humidity sensor 50d, and the soil temperature sensor 50e, and any combination of these is possible.

[0158] The communication device 170 is a communication module that communicates with the support device 201 via the relay station 200, and can output various information to the outside. The communication device 170 can perform wireless communication using, for example, the IEEE802.11 series of communication standards such as Wi-Fi (Wireless Fidelity, registered trademark), BLE (Bluetooth (registered trademark) Low Energy), LPWA (Low Power, Wide Area), and LPWAN (Low-Power Wide-Area Network). The communication device 170 can also perform wireless communication using, for example, a mobile phone communication network or a data communication network.

[0159] The control device 160 is a device that performs various controls of the water management device 100. The control device 160 is composed of electric and electronic circuits, a CPU, etc. The control device 160 controls the opening and closing of the valve body 102 and the movement of the partition part 125 by issuing commands to operate the water supply part 105 and the drainage part 106 based on commands from the outside or detection values ​​(water level, water temperature, air temperature, humidity, soil temperature, etc.) detected by the detection device 150.

[0160] Water management device 100 is equipped with observation camera 180. Observation camera 180 is a CCD camera, a CMOS camera, or an infrared camera. Power is supplied to observation camera 180 from power storage device 141 via power supply line PL1, and observation camera 180 operates with the power from power storage device 141. Observation camera 180 includes visible light camera 180a that captures images in the visible light frequency band, and infrared camera 180b that captures images in the infrared frequency band. Observation camera 180 may have a movement mechanism that changes the shooting direction of observation camera 180.

[0161] 18A shows a state in which water management apparatuses 100 on the water supply side and drainage side are arranged in relation to a field H1. The water management apparatus 100 installed in the field H1 is associated with the field H1. For example, the apparatus identification information (name, model number, manufacturing number, serial code, etc.) of the water management apparatus 100 is associated with the field identification information (name, management number, etc.) of the field H1 and stored in the support device 201. The installation position (latitude, longitude) of the water management apparatus 100 is also associated with the identification information of the field H1 or the installation position (latitude, longitude) of the field H1 and stored in the support device 201.

[0162] <Support device 201> 1B, the support device 201 performs various settings for the water management apparatus 100 based on instructions from the terminal device 33B, and is capable of storing various states of the water management apparatus 100, the environmental conditions of the field H1, etc. The support device 201 is, for example, a server or a fixed personal computer. The support device 201 may also be an arithmetic processing device provided in the information processing device 33C.

[0163] The relay station 200 is a communication unit that relays communication between the communication device 170 of the water management device 100 and the support device 201. In this embodiment, the field water management system 4 performs indirect communication by including the relay station 200, but the communication device 170 of the water management device 100 and the support device 201 may also perform direct communication, and the communication method is not limited.

[0164] The support device 201 includes a storage device 246 that stores various information, data, and the like. The storage device 246 includes, for example, a growth database 220. The support device 201 includes a clock unit 248 that measures time. The clock unit 248 is a timer, an RTC (real-time clock), or the like, and measures the year, month, date, and time (hours, minutes).

[0165] The detection values ​​(water level, water temperature, air temperature, humidity, soil temperature, etc.) detected by the detection device 150, the state of the water supply unit 105 and the drainage unit 106 (i.e., the state of opening / closing of the valve body 102 and the movement of the partition unit 125), and time information (date and time) indicating the time of the detection or the time of the change in state are associated with each other and stored in the storage device 246 of the support device 201 for each field H1. Specifically, the storage device 246 stores the environmental information of the field (including the detection values ​​detected by the detection device 150) associated with the time information and for each field. The storage device 246 also stores the water management work (deep water, shallow water, intermittent, mid-season drainage, intermittent, irrigation at low temperature, shallow water, intermittent, drainage, etc.) as the work information of the water management device 100 associated with the time information and for each field. Furthermore, the states (operation records) of the water supply unit 105 and the drainage unit 106 of the water management device 100 are stored in the storage device 246 in association with time information and distinguished for each field. The support device 201 transmits various information (e.g., environmental information and work information) stored in the storage device 246 to the information processing device 33C, and the information is stored in the storage device 46 of the information processing device 33C.

[0166] The field water management system 4 has an irrigation mode and a growth monitoring mode. The field water management system 4 may have either the irrigation mode or the growth monitoring mode. When the terminal device 33B connects to the support device 201 and performs a predetermined operation, it can be set to either the irrigation mode or the growth monitoring mode. It is also possible to set both the irrigation mode and the growth monitoring mode simultaneously in the field water management system 4. <Irrigation mode> When the irrigation mode is set by operating the terminal device 33B, the support device 201 displays a setting screen M1 on the display device 33B1 of the terminal device 33B, as shown in Fig. 18B. The setting screen M1 displays a unit selection section 210 for inputting an irrigation unit (control unit), an irrigation selection section 211, a water level setting section 212, a detailed setting button 213, and a time setting section 214.

[0167] In the unit selection section 210, whether to set in field units (each field H1) or in a group of a plurality of predetermined fields H1 is input. When field units are selected, irrigation can be performed in field H1 units, and when a group is set, irrigation can be performed in a group of a plurality of fields H1. The irrigation selection section 211 can select constant flooding, overflow, stop, etc. In the constant flooding, irrigation (water supply) is performed when the water level falls below the control width from the set water level, and irrigation (water supply) is stopped when the water level exceeds the set water level. Overflow is a setting in which irrigation (water supply) is performed regardless of the setting. Stop is a setting in which irrigation (water supply) is stopped regardless of the setting. The water level setting section 212 sets the upper limit value of the water level (upper water level).

[0168] When the detailed setting button 213 is selected, as shown in FIG. 18C, the support device 201 displays a setting screen M2 on the display device 33B1 of the terminal device 33B. In the setting screen M2, a control width input section 215 and a valve opening input section 216 are displayed. The control width input section 215 is a section for inputting a control width F1, which is a numerical value indicating a width from the upper limit water level, as shown in FIG. 18D. By setting the control width F1, the lower limit value of the water level (lower limit water level) is determined. If a very small value such as less than 1 cm is input as the control width F1 in the control width input section 215, a warning is displayed on the setting screen M2 to urge the user not to input a very small value in the control width input section 215. The valve opening input section 216 inputs the opening C1 of the on-off valve 100c (valve body 102).

[0169] The time setting section 214 is a section for setting whether or not irrigation is performed depending on the time of day, and when "ON" is selected, it is possible to set the irrigation start time and irrigation end time. When "OFF" is selected, irrigation is performed based on the irrigation setting information regardless of the time.

[0170] As described above, the irrigation setting information (field unit, group unit, constant flooding, overflow, stop, upper water level, control range F1, irrigation start time, irrigation end time) set by the setting screens M1 and M2 is stored in the storage device 203 provided in the support device 201. The support device 201 transmits the irrigation setting information (field unit, group unit, constant flooding, overflow, stop, upper water level, control range F1, opening C1, irrigation start time, irrigation end time) to the communication device 170 of the water management device 100.

[0171] Furthermore, when the support device 201 is set to the irrigation mode, it transmits this information to the water management device 100. When the communication device 170 of the water management device 100 receives this information, the control device 160 performs an operation corresponding to the irrigation mode. In the irrigation mode, the control device 160 controls the supply of water to the field H1.

[0172] As shown in FIG. 1B, the control device 160 of the water management device 100 includes a water level control unit 160A and a water level range change unit 160B.

[0173] As shown in Fig. 18D, the water level control unit 160A controls the valve element 102 so that the water level (detected water level) F2 detected by the water level sensor 50a falls within the control width F1. When a constant flooding is set, if the detected water level F2 falls and approaches the lower limit water level, the water level control unit 160A sets the valve element 102 to the opening degree C1 set by the irrigation setting information and performs irrigation to supply irrigation water to the field H1. On the other hand, if the detected water level F2 rises and approaches the upper limit water level, the water level control unit 160A operates the valve element 102 so that the valve element 102 is fully closed, stopping irrigation (water supply). The water level control unit 160A may not use the water level detected by the water level sensor 50a until the water surface stabilizes. For example, the water level (detected water level) may not be used to control the valve body 102 for a predetermined time (water level stop time) after water supply is started, or the water level sensor 50a may not measure the water level immediately after the valve body 102 is opened. The water level stop time may be set according to the season. For example, when the ears of rice are large, the water level sensor 50a may measure the water level after the start of water supply, but the detection value after a certain time has passed (water level stop time has passed) may be detected as the actual water level.

[0174] Furthermore, when constant flooding and an irrigation start time and an irrigation end time are set (constant flooding with time zone), if the detected water level F2 falls and approaches the lower limit water level during the time zone between the irrigation start time and the irrigation end time, the water level control unit 160A sets the valve 102 to the opening degree C1 set by the irrigation setting information and performs irrigation to supply irrigation water to the field H1. On the other hand, if the detected water level F2 rises and approaches the upper limit water level, the water level control unit 160A operates the valve 102 so that the valve 102 is fully closed, and stops irrigation (water supply). In other words, in the case of constant flooding with time zone, the valve 102 is repeatedly opened and closed during the time zone.

[0175] If the number of opening and closing operations of the valve body 102 reaches or exceeds a predetermined number within a predetermined time (for example, one day), the water level control unit 160A notifies the support device 201 via the communication device 170 that "the number of opening and closing operations has reached or exceeds a predetermined number." The support device 201 notifies that "the number of opening and closing operations has reached or exceeds a predetermined number" within a predetermined time.

[0176] The water level range change unit 160B changes (corrects) the control range F1 of the irrigation setting information. As shown in Fig. 18E, the control device 160 stores, for example, in a storage device that the control device 160 has or in a storage device connected to the control device 160, periods (water management periods) corresponding to deep water, shallow water, intermittent, mid-season drainage, intermittent, low temperature irrigation, shallow water, intermittent, and drainage in order from the time of transplanting seedlings as water management for the field. The control device 160 also stores numerical values ​​A1, AW2, and AW3 of the control range F1 corresponding to the water management periods. The control device 160 stores openings AW4, AW5, and AW6 corresponding to the water management periods.

[0177] For example, in the case of a period T1 of deep water, shallow water, or intermittent water after transplanting seedlings, if the control width (set control width) F1 indicated by the irrigation setting information matches the numerical value A1, the water level width change unit 160B does not change the control width F1. On the other hand, in the case of period T1, if the control width F1 and the numerical value A1 do not match, the water level width change unit 160B changes (corrects) the control width F1 in period T1 to the numerical value A1.

[0178] Furthermore, for example, in the case of period T1, if the opening (set opening) C1 indicated by the irrigation setting information matches the value AW4, the water level width change unit 160B does not change the opening C1. On the other hand, in the case of period T1, if the opening C1 and the value AW4 do not match, the water level width change unit 160B changes (corrects) the opening C1 in period T1 to the value AW4.

[0179] In the case of period T2 of mid-season drainage, intermittent watering, or low-temperature irrigation, if the control range F1 matches the value AW2, the water level range change unit 160B does not change the control range F1. On the other hand, in the case of period T2, if the control range F1 and the value AW2 do not match, the water level range change unit 160B changes (corrects) the control range F1 in period T2 to the value AW2.

[0180] Also, for example, in the case of period T2, when the opening degree C1 matches the numerical value AW5, the water level width change unit 160B does not change the opening degree C1. On the other hand, in the case of period T2, when the opening degree C1 and the numerical value AW5 do not match, the water level width change unit 160B changes (corrects) the opening degree C1 in period T2 to the numerical value AW5.

[0181] If the control width F1 matches the value AW3 during the period T3 of shallow water, intermittent water, or falling water, the water level width change unit 160B does not change the control width F1. On the other hand, if the control width F1 does not match the value AW3 during the period T3, the water level width change unit 160B changes (corrects) the control width F1 in the period T2 to the value AW3.

[0182] Also, for example, in the case of period T3, when the opening degree C1 matches the numerical value AW6, the water level width change unit 160B does not change the opening degree C1. On the other hand, in the case of period T3, when the opening degree C1 does not match the numerical value AW6, the water level width change unit 160B changes (corrects) the opening degree C1 in period T2 to the numerical value AW6.

[0183] That is, the water level width change unit 160B limits the lower limit value of the control width F1 when the control width F1>AW1, control width F1>AW2, and control width F1>AW3 in each of the periods T1, T2, and T3. Also, the water level width change unit 160B limits the opening degree C1 when the opening degree C1>AW5, opening degree C1>AW6, and opening degree C1>AW6 in each of the periods T1, T2, and T3. Also, since the water level width change unit 160B changes the opening degree C1 according to the control widths AW1, AW2, and AW3, the opening operation time, that is, the opening degrees AW4, AW5, and AW6 are variable according to the control widths AW1, AW2, and AW3. For example, in the case of (valve open time) / (total time of valve open and valve closed) shown in FIG. 18D, the opening degree is expressed as a percentage (%).

[0184] In the above-described embodiment, the control device 160 stores the relationship between the periods T1, T2, T3 and the control ranges AW1, AW2, AW3 and the openings AW4, AW5, AW6, and changes the control ranges AW1, AW2, AW3 and the openings AW4, AW5, AW6 based on the periods T1, T2, T3. However, the water level range change unit 160B may change the control ranges AW1, AW2, AW3 or the openings AW4, AW5, AW6 based on the growth of the crop U1 in the field H1.

[0185] An observation camera 180 captures an image of a crop U1 such as rice from the side, capturing an image of the growth of the crop U1. The water level width change unit 160B includes a determination unit 160B1 that estimates the size (grass height (back height)) X1 of the crop U1 from, for example, observation data (captured image) captured by the observation camera 180, and determines whether the time corresponds to any of the following periods: deep water, shallow water, intermittent, mid-season drainage, intermittent, low-temperature irrigation, shallow water, intermittent, or drainage. When the determination unit 160B1 determines that the time corresponds, the water level width change unit 160B changes the control widths AW1, AW2, AW3 and the openings AW4, AW5, AW6. In other words, the water level width change unit 160B determines the growth stage, such as the rooting stage, tillering stage, panicle differentiation stage, booting stage, flowering stage, ripening stage, etc., from the state of the crop U1 in the captured image using the determination unit 160B1, and changes the control widths AW1, AW2, AW3 and the openings AW4, AW5, AW6 according to the growth stage determined by the determination unit 160B1. Note that the control device 160 (water level width change unit 160B) may determine the state of the crop U1 by pattern matching between the captured image and a reference image that serves as a determination criterion for the crop U1.

[0186] The water level width change unit 160B increases the control widths AW1, AW2, and AW3 as the crop U1 grows (the growth stage progresses). The water level width change unit 160B decreases the openings AW4, AW5, and AW6 as the crop U1 grows (the growth stage progresses), for example. Note that the above-mentioned control widths AW1, AW2, and AW3 and openings AW4, AW5, and AW6 are merely examples, and may be freely changed depending on the geology of the field H1, the regional system, the type (brand) of the crop U1, and the numerical values ​​of the control widths AW1, AW2, and AW3 and openings AW4, AW5, and AW6 may be obtained from past performance, simulations, and the like.

[0187] <Growth monitoring mode> When the growth monitoring mode is set by operating the terminal device 33B, the support device 201 transmits to the water management device 100 that the growth monitoring mode has been set. When the communication device 170 of the water management device 100 receives the growth monitoring mode, the control device 160 performs an operation corresponding to the growth monitoring mode. In the growth monitoring mode, the control device 160 monitors the crop U1 in the field H1.

[0188] In the growth monitoring mode, the observation camera 180 captures an image of the crop U1 from the side (lateral direction) and transmits the captured observation data to the support device 201 via the communication device 170.

[0189] The observation camera 180 captures an image of the range from the root side to the tip of the crop U1. When the observation camera 180 captures an image of the crop U1, the control device 160 adjusts the position of the observation camera 180 to capture an image of the range from the root side to the tip of the crop U1.

[0190] For example, when the observation camera 180 is a visible light camera 180a, the water management device 100 transmits to the support device 201 the device identification information, the image capturing time, and the captured image (crop image) of the crop U1 captured by the visible light camera 180a as observation data.

[0191] When the observation camera 180 is the infrared camera 180b, the water management apparatus 100 transmits the apparatus identification information, the image capturing time, and the crop image captured by the infrared camera 180b to the support apparatus 201 as observation data.

[0192] When the observation camera 180 is a visible light camera 180a and an infrared camera 180b, the water management device 100 transmits the device identification information, the image capturing time, and the crop images captured by the visible light camera 180a and the infrared camera 180b to the support device 201 as observation data.

[0193] The support device 201 stores the observation data (device identification information, image capture time (date, time), and crop image) transmitted from the water management device 100 in the growth database 220. In the above-mentioned embodiment, the observation data is captured from the side of the crop U1 and transmitted to the support device 201. In addition to this, the water level detected by the water level detection device (water level sensor) 50a and the water temperature detected by the water temperature detection device (water temperature sensor) 50b may be transmitted as observation data and stored in the growth database 220.

[0194] 1A is capable of identifying correlation information for a plurality of fields in a designated area DA and reporting the information via terminal devices 33A and 33B. This configuration will be described below. The information processing device 33C includes a control device 45 and a storage device 46. The control device 45 includes an electric / electronic circuit, a CPU, etc.

[0195] Fig. 19A is a diagram showing an example of multiple pieces of production management information for each field stored in a storage device. As shown in Fig. 19A, storage device 46 stores multiple pieces of production management information related to crop production management in the fields, distinguishing them for each of the multiple fields. Fig. 19A shows multiple pieces of production management information related to crop production management for the nth field out of the first to nth fields. The production management information includes multiple pieces of crop information related to crops grown in the field, multiple pieces of work information carried out in the field, and environmental information of the field.

Damaged grains include cracked grains, broken grains, and stink bug (spotted grains). The production information further includes the grain size rate, moisture content at harvest, and protein content at harvest.

[0197] The work information includes rice planting work, fertilization work, pest control work, harvesting work, and water management work. Rice planting work includes, for example, the rice planting date, spacing information, and type of seedlings. Fertilization work includes, for example, the fertilization date, dilution rate / amount of sprayed material (e.g., fertilizer), and fertilizer name or type. Pest control work includes, for example, pest control date, dilution rate / amount of sprayed material (e.g., chemical solution), and chemical solution name or type. Water management work includes, for example, deep water, shallow water, intermittent, mid-season drying, intermittent, irrigation at low temperature, shallow water, intermittent, and drainage.

[0198] The environmental information includes the air temperature, accumulated temperature, water temperature, and water level of the field. Alternatively, it may be divided into a predetermined growth period. Here, the environmental information is collected for multiple months (May to October). ) are divided into the air temperature, accumulated temperature, water temperature and water level of the field. Multiple months (May to October) may be treated as one.

[0199] The information processing device 33C identifies, for a plurality of fields in the designated area DA, production management information that is correlated with the selected production management information from among the plurality of pieces of production management information stored in the storage device 46, as correlation information. The terminal devices 33A and 33B notify the correlation information identified by the information processing device 33C.

[0200] The control device 45 includes a reception unit 45a, a designation unit 45b, an extraction unit 45c, a calculation unit 45d, and a For example, the control device 45 includes a CPU that executes a control program. By this, the reception unit 45a, the designation unit 45b, the extraction unit 45c, the calculation unit 45d, and the identification unit 45e It functions as part 45e.

[0201] The reception unit 45a receives the selection of the crop information by the user. The content of the crop information received by the unit 45a is stored in a storage device, The information is extracted based on the crop information for each of a plurality of fields in the designated area DA stored in the storage unit 46. For example, if the value of the crop information of the field is within a predetermined acceptable range, the extraction unit 45c The field is extracted as a good field, and if it is within a predetermined range of bad judgment, the field is extracted as a bad field. and extract.

[0202] The designation unit 45b accepts the designation of the designated area DA by the user. The designation unit 45b extracts good and bad fields from the designated area DA received.

[0203] When the first confirmation instruction is received, the calculation unit 45d displays the crop information selected from the plurality of crop information. The content of the information is good for good fields and bad for bad fields, and multiple pieces of work information and environmental information are For example, the calculation unit 45d calculates the correlation coefficients of the good fields extracted by the extraction unit 45c. Correlation coefficients of the multiple pieces of work information and environmental information are calculated for the cultivated field and the non-cultivated field, respectively.

[0204] The specification unit 45e specifies information whose correlation coefficient is a specified value as correlation information. The specification unit 45e specifies the name of the correlation information, the degree of influence of the correlation information, and the detailed content of the correlation information. The information processing device includes a data generating unit 45f. The data generating unit 45f is composed of an electric / electronic circuit, a CPU, etc. Generate a correspondence table CT1 that associates the name, impact level, and detailed content of the correlation information identified by 5e. The terminal device 33A is provided with a display device 56 that displays the correspondence table CT1. 3B includes a display device 33B1 that displays the correspondence table CT1.

[0205] The data generating unit 45f generates a plurality of data sets for at least one of the good and bad fields. A work performance calendar CL is generated in which the work information is arranged in chronological order. The device 33B1 displays the correspondence table CT1 and the work result calendar CL.

[0206] The storage device 46 stores a map including the designated area DA. The determining unit 45e determines whether or not a farm work improvement message is generated based on the name, the degree of impact, and the detailed content of the correlation information specified by the determining unit 45e. Sage MS3 is created, which includes good and bad fields and displays good and bad fields in different ways. Generate a correlation map screen M5 including the map to be displayed by the user and the farm work improvement message MS3. The display device 56 or the display device 33B1 displays a map screen.

[0207] The data generating unit 45f determines whether at least one of the water temperature and the water level of the field is relative in the identifying unit 45e. When the information is identified as relevant information, the water temperature of the field is sent as a farming work improvement message MS3. and a message for improving at least one of the water level and the water temperature is generated, and the message is output to the specifying unit 45e. When at least one of the temperature and the accumulated temperature of the place is identified as correlation information, A message is generated to prompt a change to a crop variety corresponding to the accumulated temperature.

[0208] The display device 56 or the display device 33B1 displays a list of corresponding data, which associates at least one of color sorting information and production information for each field, for a plurality of unsuitable fields, and displays the list in the order of information selected by the user from damaged grains, white immature grains, discolored grains, yield, and yield rate, as well as displaying a map including good and unsuitable fields.

[0209] When a name in correspondence table CT1 is selected by the user, display device 56 or display device 33B1 displays a graph showing the measurement results of information related to the name out of the work information and environmental information.

[0210] According to the agricultural management system 1 of this embodiment, multiple pieces of production management information for each field are stored in the information processing device 33C, and by specifying the area to be checked on a field map including multiple fields and selecting a check item, the information processing device 33C can identify correlation information that is correlated with the check item, and the identified correlation information can be displayed on the terminal devices 33A and 33B.

[0211] Using Fig. 19B, a correlation information display process for confirmation items by the information processing device 33C will be described. Fig. 19B is a flowchart showing an example of the correlation information display process of the first embodiment. Here, a case where correlation information is displayed on the terminal device 33B will be described. A case where correlation information is displayed on the terminal device 33A is the same as that of the terminal device 33B, and detailed description thereof will be omitted here since it is only necessary to read the terminal device 33B as the terminal device 33A.

[0212] First, the information processing device 33C permits the login of the terminal device 33B based on user information (e.g., user identification information) from the terminal device 33B. If the user information is legitimate information, the information processing device 33C permits the login, and if the user information is not legitimate information, the information processing device 33C does not permit the login. For example, if the received user identification information matches the identification information of a legitimate user already stored in the storage device 46, the information processing device 33C permits the login.

[0213] After permitting login of terminal device 33B, when information processing device 33C receives a map display request from the user from terminal device 33B, it transmits display information corresponding to the map display request to terminal device 33B. For example, based on the user information from terminal device 33B, information processing device 33C identifies a field owned by the user indicated by the user information, and transmits display information including a map including the identified field to terminal device 33B.

[0214] Based on the display information from the information processing device 33C, the terminal device 33B displays a setting screen M3 of a map including a plurality of fields on the display device 33B1 as shown in Fig. 20. Fig. 20 is a diagram showing an example of a screen display of the terminal device. The setting screen M3 shown in Fig. 20 has, for example, a first display area G1 at the top, a second display area G2 in the middle, and a third display area G3 at the bottom.

[0215] The first display area G1 displays a selection tab ST1 for selecting the actual farming period (e.g., year) to be confirmed, a selection tab ST2 for selecting the confirmation item, a selection tab ST3 for selecting the display color of the field, a selection tab ST4 for selecting the region designation mode or the field designation mode, and a selection tab ST5 for selecting the crop (e.g., rice) variety.

[0216] The user can select one performance year from among multiple performance years by performing a selection operation (e.g., a pull-down operation) on the selection tab ST1. Here, FIG. 20 shows a state in which "2020" is selected as the performance year.

[0217] The user can select (e.g., pull down) the selection tab ST2 to set one of multiple confirmation items. For example, either the "color sorting information" or "production information" items shown in FIG. 19A can be selected. For "color sorting information", items such as "stink bugs", "cracked grains", "broken grains", "white rice", "discoloration", and "dead rice" can be selected. For "production information", items such as "yield", "yield per ton", "yield rate", "grain size", "moisture content", and "protein" can be selected. Here, FIG. 20 shows a state in which "white rice" from "color sorting information" has been selected as a confirmation item.

[0218] The color setting can be selected by the user's selection operation (e.g., pull-down operation) on the selection tab ST3. For example, at least the color of good fields (e.g., green) and the color of bad fields (e.g., red) can be selected and set. In this case, fields other than good and bad fields are not colored (displayed with the background color). Note that the color of fields other than good and bad fields (e.g., yellow) may also be selected and set.

[0219] The user can select the area designation mode or the field designation mode by performing a selection operation (e.g., a pull-down operation) on the selection tab ST4. In the area designation mode, an area including multiple fields can be designated. In the field designation mode, at least one field can be designated. Here, as shown in FIG. 20, the "area designation mode" has been selected by the user, and therefore "area designation", which indicates the area designation mode, is shown to be selected.

[0220] By the user selecting (e.g., using a pull-down menu) the selection tab ST5, the user can set the target crop varieties to either "select all," "similar varieties," or "same variety." Here, FIG. 20 shows a state in which "select all" has been selected, indicating that the target crop varieties are all types. When the user selects "similar varieties," a variety input field is displayed in the first display area G1, and the variety entered in the variety input field and its similar varieties are selected as the target crops. When the user selects "same variety," a variety input field is displayed in the first display area G1, and only the variety entered in the variety input field is selected as the target crops.

[0221] The second display area G2 displays a map image MP1 including a plurality of farm fields. The third display area G3 displays various messages. For example, the third display area G3 displays a message MS1, such as "Please specify the area you wish to check," which prompts the user to specify the area he or she wishes to check, and a message MS2, such as "Please select the item to check," which prompts the user to select the item to check.

[0222] As shown in FIG. 19B, when the designation unit 45b accepts the designation of the designated area DA by the user, the control device 45 of the information processing device 33C sets the designated area DA (S1). For example, the designation unit 45b accepts an instruction designated by the user at the terminal device 33B. The control device 45 sets the designated area DA accepted by the designation unit 45b. More specifically, the user sees the message MS1 shown in FIG. 20, and sets the designated area DA as shown in FIG. 20 for the map image MP1 on the setting screen M3 shown in FIG. 20 of the terminal device 33B. For example, the user can set the designated area DA for the field map by dragging the cursor.

[0223] Also, because "Select All" is selected in the selection tab ST5, all fields within the designated area DA are targeted. If "Similar Varieties" is selected in the selection tab ST5, then of all the fields within the designated area DA, the fields that are targeted are the variety entered in the variety input field and its similar varieties. If "Same Variety" is selected in the selection tab ST5, then of all the fields within the designated area DA, only the fields of the variety entered in the variety input field are targeted.

[0224] When the user selects crop information on the setting screen M3 shown in FIG. 20 of the terminal device 33B, the reception unit 45a receives the selection. As shown in FIG. 19B, the control device 45 selects the selection received by the reception unit 45a, that is, the crop information selected by the user, as a confirmation item (S2). Specifically, when the user operates the selection tab ST2, multiple selectable crop information are displayed in a pull-down menu. The multiple crop information includes color sorting information such as damaged grains (such as stink bugs), white immature grains (white rice), dead rice, and colored grains (scorched), and production information such as yield, yield rate, grain size adjustment rate, moisture content at harvest, and protein content at harvest. One piece of crop information can be selected from the multiple crop information and set as a confirmation item. When the user selects white immature grains (white rice) as shown in FIG. 20, the control device 45 sets "white rice" as a confirmation item.

[0225] When the user operates the button image BT1 (see FIG. 20) indicating OK, the extraction unit 45c extracts good fields where the content of "sirata" that is the crop information accepted by the acceptance unit 45a is good and bad fields where the content is bad, based on the crop information for each of the multiple fields in the designated area DA stored in the storage device 46 (S3). For example, if the value of "sirata" that is the crop information of a field is within a predetermined good judgment range (e.g., less than 0.05% for sirata), the extraction unit 45c extracts the field as a good field, and if the value is within a predetermined bad judgment range (e.g., 0.2% or more for sirata), the extraction unit 45c extracts the field as a bad field. Here, the extraction unit 45c extracts 10 fields indicated by diagonal hatching as good fields and 13 fields indicated by cross hatching as bad fields. Note that the good judgment range and the bad judgment range are not limited to the above and may be other values.

[0226] Fig. 21 is a diagram showing an example of a screen display of a terminal device 33B. As shown in Fig. 21, the terminal device 33B displays a color selection map screen M4 including 10 good fields and 13 bad fields extracted by the extraction unit 45c.

[0227] The control device 45 creates list data that displays crop information (color sorting information and production information) for each unacceptable field extracted by the extraction unit 45c. The display device 33B1 of the terminal device 33B displays the list data received from the information processing device 33C on a color selection map screen M4. Specifically, the display device 33B1 displays a map image MP2 that distinguishes between good and unacceptable fields in the second display area G2, as shown in FIG. 21. In the second display area G2 shown in FIG. 21, 10 good fields indicated by diagonal hatching are displayed, and 13 unacceptable fields indicated by cross hatching are displayed.

[0228] The display device 33B1 displays a color selection map screen M4 displaying a list LT1 in the third display area G3. The list LT1 is a list of correspondence data for a plurality of unsuitable fields, in which at least one of color sorting information and production information is associated with each field, and is displayed in order (for example, descending order) of information selected by the user from damaged grains, white immature grains, colored grains, yield, and yield rate (here, white immature grains (white immature grains)).

[0229] The user can check the existence of good and bad fields and a list table LT1 for the confirmation item of white immature grains (sirata) among multiple fields in the specified area DA by looking at the map image MP2 shown in Fig. 21. However, the reality is that the user cannot know what measures to take to improve the white immature grains (sirata) just by looking at the map image MP2 shown in Fig. 21.

[0230] Therefore, in this embodiment, the information processing device 33C can provide the user with an awareness for improving farm work (here, improvement of white immature grains (shirata) as an example). Specific explanation will be given below.

[0231] When an operation instruction (first confirmation instruction) is given by operating the analysis button BT2 in Fig. 21, the control device 45 identifies correlation information having a correlation with the confirmation item (S4) as shown in Fig. 19B. The process of identifying correlation information is executed according to the flowchart shown in Fig. 19C. Fig. 19C is a flowchart showing an example of the correlation information identifying process of the first embodiment.

[0232] The calculation unit 45d performs production management of each of the good and bad fields for the confirmation item (here, sardines). The calculation unit 45d calculates a correlation coefficient of the information (S41). For example, when the first confirmation instruction is received, and a good field in which the content of the crop information (sirata) selected from the plurality of crop information is good. Calculate correlation coefficients of multiple pieces of work information and environmental information for each of the fields that are positive and negative. Specifically, the calculation unit 45d calculates the following for the good fields and the bad fields extracted by the extraction unit 45c: The correlation coefficient between the confirmation item Shirata and the multiple work information and environmental information shown in Figure 19A was calculated. The work information shown in FIG. 19A includes rice planting work (rice planting date) value WA1, value WA2 for rice planting work (spacing), value WA3 for rice planting work (type of seedlings), etc. , the value of fertilization work (dilution rate / amount) WB1, ..., the value of pest control work (dilution rate / amount) WC1, ..., There are harvest work (harvest date) values ​​WD1, ..., water management work values ​​WE1 to WE9, etc. The multiple pieces of environmental information shown in FIG. 19A include air temperature values ​​EA1, . . . , integrated temperature values ​​EB1, . . . , water temperature value EC1, ..., water level value ED1, etc., which are calculated for a given period (e.g. month, birth year, etc.). It is divided into multiple values ​​according to the development stage.

[0233] The specification unit 45e is configured to specify, among the correlation coefficients of the plurality of pieces of work information and the plurality of pieces of environmental information shown in FIG. Information with a correlation coefficient of a specified value ("-1 to -0.5" or "0.5 to 1") is considered as correlation information. For example, the determination unit 45e determines whether the number of the candidates is equal to or smaller than the number of the candidates calculated by the calculation unit 45d in a round-robin manner (S42). For the multiple correlation coefficients, the strength of the correlation is identified as shown in FIG. 19D. 11 is a diagram showing the relationship between the correlation coefficient and the strength of the correlation. If it is between 1 and -0.7, there is a strong negative correlation, and if it is between -0.7 and -0.5, there is a weak negative correlation. There is a correlation, if it is between -0.5 and 0.5, there is no correlation, if it is between 0.5 and 0.7, it is weak. If the correlation is between 0.7 and 1, it is determined that there is a strong positive correlation. As related information, the "average water temperature in August" and "maximum water temperature in August" show a strong positive correlation, while the "average water temperature in August" shows a weak positive correlation. Let's say that "minimum water temperature in August" is extracted, which shows a positive correlation with "minimum water temperature in August".

[0234] Next, the specification unit 45e specifies the name from the specified correlation information. For example, If the correlation information with the coefficient at the specified value is the August water temperature in the environmental information, the name of the correlation information and The determination unit 45e determines the influence of the correlation information, that is, the correlation If the numbers are strongly correlated, it is "large", if they are less correlated, it is "medium", if there is no correlation, it is "no correlation". In addition, the specification unit 45e specifies the detailed contents of the correlation information (for example, the water temperature in August) and Identify.

[0235] The data generating unit 45f generates various display data of the correlation information specified by the specifying unit 45e. For example, as shown in FIG. 23, the data generating unit 45f determines whether the specifying unit 45e A correspondence table CT1 is generated that associates the name, the impact level, and the detailed content of the identified correlation information. FIG. 23 is a diagram showing an example of a screen display of a terminal device.

[0236] The data generating unit 45f generates the name, the degree of influence, and the details of the correlation information identified by the identifying unit 45e. For example, the data generating unit 45f generates a farm work improvement message MS3 based on the content. The name of the correlation information specified by the specifying unit 45e (for example, “water temperature”), the degree of influence of the correlation information is strong, Since the correlation is small, the answer is "large." Based on the details of the correlation information (e.g., water temperature in August), FIG. 22 shows an example of a screen display of the terminal device. The farm work improvement message MS3 shown in Figure 22 is "damage to good and bad fields (here) The difference between the two varieties is strongly influenced by the water temperature during the ripening period (August). Why not reconsider this issue based on the water temperature in good farmland? The section 45f includes good fields and bad fields, and displays the good fields and the bad fields in different display modes. Generate a correlation map screen M5 including a map image MP3 and a farm work improvement message MS3. do.

[0237] As shown in Fig. 19B, the terminal device 33B displays various types of correlation information and the like (S5). As shown in Fig. 22, the terminal device 33B displays a correlation map screen M5 generated by the data generating unit 45f on the display device 33B1. In the second display area G2 of the correlation map screen M5, a first group GD indicating a group of good fields and a second group NGD indicating a group of bad fields are displayed. The first group GD includes 10 good fields indicated by diagonal hatching. The second group NGD includes 13 bad fields indicated by cross hatching.

[0238] In addition, the data generating unit 45f generates information on a plurality of works carried out in good farm fields as shown in FIG. The calendar CL shows the work results of good fields, which are arranged in chronological order, and the calendar CL shows the work results of bad fields. A field work performance calendar CL is generated by arranging the information in chronological order (S43).

[0239] When the user selects the details button BT3 on the correlation map screen M5, the terminal device 33B displays a details screen M6 on the display device 33B1, as shown in Fig. 23. The details screen M6 is a screen including the correspondence table CT1 and the work performance calendar CL of good and bad fields generated by the data generating unit 45f.

[0240] The correspondence table CT1 of the detail screen M6 shown in Fig. 23 is a table that associates the name of correlation information (for example, factors), the degree of impact, and detailed content. This correspondence table CT1 shows that the correlation information includes average water temperature, maximum water temperature, and minimum water temperature, and that their impacts are "large," "large," and "medium," and that the details are "there is a strong positive correlation with the August data," "there is a strong positive correlation with the August data," and "there is a weak positive correlation with the August data." Note that for the accumulated temperature, rice planting date, distance between plants, pest control, and mid-drying period, the correlation coefficients were outside the specified values, so the impact is shown to be "none," and the details are shown to be "irrelevant."

[0241] The work performance calendar CL for good fields and the work performance calendar CL for bad fields on the detailed screen M6 shown in Figure 23 display the work performance of transplanting, pest control, ripening, pest control, drainage, and harvesting in calendar format. Here, although differences can be confirmed between good fields and bad fields in the timing of transplanting and pest control before ripening, the difference shows no correlation with "white rice."

[0242] The detail screen M6 shown in Fig. 23 includes a detailed improvement message MS4 that explains the content of the farm work improvement message MS3 in more detail. The detailed improvement message MS4 is generated by the data generating unit 45f.

[0243] When any of the names of multiple pieces of correlation information (e.g., factors) on the detailed screen M6 shown in Fig. 23 is selected, the information processing device 33C transmits to the terminal device 33B a graph showing the measurement results of information related to the name of the correlation information (e.g., water temperature) (e.g., water temperature and air temperature in good and bad fields, water levels in good and bad fields, open / close state of the water supply unit 105 of the water management device 100, and precipitation). Fig. 24 is a graph showing the measurement results of information related to the correlation information. As shown in Fig. 24, the terminal device 33B displays a graph showing the measurement results of the water temperature and air temperature in good and bad fields, and a graph showing the measurement results of the water levels in good and bad fields, the open / close state of the water supply unit 105 of the water management device 100, and the amount of precipitation.

[0244] In FIG. 22, a case where the user selects white immature grains (shirata) in the selection tab ST2 has been described, but the present invention is not limited to this. Any confirmation item can be selected in the selection tab ST2. FIG. 25A is a diagram showing an example of a screen display of a terminal device. For example, as shown in FIG. 25A, when the user selects stink bugs, which are an example of damaged grains, in the selection tab ST2 (S2), the control device 45 of the information processing device 33C sets "stink bugs" as a confirmation item, and the extraction unit 45c extracts good and bad fields for "stink bugs" (S3). The control device 45 identifies correlation information that is correlated with "stink bugs" (S4). The terminal device 33B uses the correspondence table CT1 generated by the data generation unit 45f of the information processing device 33C to display various correlation information of "stink bugs" and the like (S5). The terminal device 33B displays the correlation map screen M5 shown in FIG. 25A, which is generated by the data generation unit 45f. The farm work improvement message MS3 shown in FIG. 25A states, "There is a strong correlation between stink bug damage and transplanting timing in good and bad fields."

[0245] In this way, even if "stink bugs" is selected as a confirmation item, as shown in FIG. 25A, it is possible to provide the user with insight into how to improve the "stink bugs" problem, that is, insight into adjusting the transplanting timing of poor fields to match the transplanting timing of good fields.

[0246] Fig. 25B is a diagram showing an example of a screen display of a terminal device. In Fig. 25B, as in Fig. 25A, stink bugs are selected as a confirmation item (S2), and the control device 45 identifies correlation information correlated with "stink bugs" (S4), but the contents are different. The terminal device 33B displays the correlation map screen M5 shown in Fig. 25B, which is generated by the data generating unit 45f. The farm work improvement message MS3 shown in Fig. 25B has the content that "There is a strong correlation between stink bug damage and control timing in good and bad fields."

[0247] In this way, even if "stink bugs" is selected as a confirmation item, as shown in FIG. 25B, the user can be provided with insight into how to improve "stink bugs," that is, insight into aligning the control timing of poor fields with the control timing of good fields.

[0248] Up to this point, a case has been described in which "area designation" indicating an area designation mode is selected in the selection tab ST4 shown in Fig. 20, and correlation information correlating with the check items is identified for multiple fields in the designated area DA in the same actual farming season (same year) in Fig. 20 to Fig. 25B. Next, a case will be described below in which "field designation" indicating a field designation mode is selected in the selection tab ST4, and correlation information correlating with the check items is identified for the same field in two or more different actual farming seasons (multiple years), as shown in Fig. 26A. Fig. 26A is a diagram showing an example of a screen display of a terminal device.

[0249] The storage device 46 stores the production management information of the first to nth fields shown in FIG. 19A, distinguishing between the multiple fields and between the multiple farming seasons. For example, the storage device 46 stores the production management information of the first to nth fields in association with farming season information (e.g., information on 2018, 2019, 2020, etc.) indicating the year or time of the farm work. For this reason, the farming season information is stored in association with each of the multiple pieces of work information shown in FIG. 19A or with the entirety of the work information. In short, the storage device 46 stores the production management information of the same field, distinguishing between the multiple farming seasons based on the farming season information.

[0250] 26A, the display device 33B1 displays the setting screen M7. When the user selects "Field designation" indicating the field designation mode in the selection tab ST4, the display device 33B1 displays a message MS5, such as "Please specify the field and multiple years," which prompts the user to designate the field and multiple years that the user wants to confirm, and a message MS6, such as "Please select the confirmation item," which prompts the user to select the confirmation item that the user wants to confirm, in the third display area G3 of the setting screen M7.

[0251] Fig. 27A is a flowchart showing an example of correlation information display processing. As shown in Fig. 27A, the control device 45 of the information processing device 33C specifies a field and multiple farming periods (S1A). For example, when the specification unit 45b receives an instruction of the field and multiple farming periods selected by the user at the terminal device 33B, the control device 45 sets the field and multiple farming periods received by the specification unit 45b.

[0252] Specifically, the designation unit 45b accepts the designation of a field by the user. For example, when the user selects any one of the multiple fields in the map image MP1 in the second display area G2, the designation of the selected field is accepted by the designation unit 45b. As shown in FIG. 26A, assume that a designated field DF is selected by the user's selection operation. When the designation unit 45b accepts the designation of the field, the control device 45 causes at least one of the designated field name and field number to be displayed on the terminal device 33B. In FIG. 26A, the field number "E9" of the designated field DF is displayed in the third display area G3 of the setting screen M7.

[0253] The designation unit 45b accepts the designation of multiple agricultural periods (e.g., years) by the user. The user can select the "multiple" item indicating the multiple years designation item from multiple performance years by performing a selection operation (e.g., a pull-down operation) on the selection tab ST1. In FIG. 26A, the "multiple" item is selected on the selection tab ST1. When the multiple years designation item is selected, the terminal device 33B displays an input field in which the start year and the end year can be input in the third display area G3 of the setting screen M7. The user inputs a numerical value indicating the start year (e.g., 2018) and a numerical value indicating the end year (e.g., 2020), and the designation unit 45b accepts the input designation of multiple agricultural periods (i.e., multiple years). For example, the years "2018-2020" are designated. The control device 45 sets the years "2018-2020" as multiple agricultural periods.

[0254] As shown in Fig. 27A, the control device 45 selects the selection received by the reception unit 45a, i.e., the crop information selected by the user, as a confirmation item (S2). Specifically, when the user selects crop information on the setting screen M7 shown in Fig. 26A of the terminal device 33B, the reception unit 45a accepts the selection. Here, as in the first embodiment, it is assumed that the user selects white immature grains (white rice) as shown in Fig. 26A, and the control device 45 sets "white rice" as a confirmation item.

[0255] When an operation instruction (second confirmation instruction) is given to the multiple year analysis button BT4 in Fig. 26A, the control device 45 identifies correlation information that is correlated with the confirmation item, as shown in Fig. 27A (S3A). The process of identifying correlation information is executed according to the flowchart shown in Fig. 27B. Fig. 27B is a flowchart showing an example of the correlation information identifying process.

[0256] When there is a second confirmation instruction different from the first confirmation instruction (for example, an instruction to operate the multiple year analysis button BT4 in Figure 26A), the calculation unit 45d calculates correlation coefficients of multiple work information and environmental information for good farming periods where the content of the crop information selected by the user is good and bad farming periods where the content of the crop information selected by the user is bad, for the production management information of the same field divided into multiple farming seasons, as shown in Figure 27B (S301).

[0257] Specifically, when the multiple year analysis button BT4 is operated, the calculation unit 45d extracts a good farming period and a bad farming period for the production management information of the specified field DF (field number "E9") for the multiple farming periods (here, the years "2018-2020") shown in FIG. 26A, in which the content of the crop information "Shirata", which is a confirmation item, is good. For example, if the value of "Shirata" for the year "2018" is within the good judgment range, the year "2018" is extracted as a good farming period, and if it is within the bad judgment range, the year "2018" is extracted as a bad farming period. Here, it is assumed that "2018" and "2019" are extracted as good farming periods, and "2020" is extracted as a bad farming period. Next, the calculation unit 45d calculates the correlation coefficients of the multiple work information and environmental information shown in FIG. 19A for the good farming period and the bad farming period in a brute force manner.

[0258] The identification unit 45e identifies, as correlation information, information whose correlation coefficient is a specified value ("-1 to -0.5" or "0.5 to 1") among the correlation coefficients of the multiple pieces of work information and environmental information shown in Fig. 19A (S302). Here, it is assumed that only "average water temperature in August", which shows a strong positive correlation, is extracted as correlation information.

[0259] The data generating unit 45f generates various display data such as correlation information of the same field in multiple farming seasons identified by the identifying unit 45e (S303). Fig. 26B is a diagram showing an example of a screen display of a terminal device. For example, as shown in Fig. 26B, the data generating unit 45f generates a correlation map screen M8 including a map image MP3 including a designated field DF selected by the user and a farm work improvement message MS7.

[0260] The farm work improvement message MS7 shown in Figure 26B states, "The difference in damage between the good farming season (2018-2019) and the bad farming season (2020) is strongly influenced by the water temperature during the ripening period (August). Why not reconsider this based on the water temperature during the good farming season?"

[0293] Specifically, when the correlation information is information indicating the water temperature in the field, the control device 45 By controlling the irrigation unit 105 and the drainage unit 106, the water supply and drainage to the field are adjusted to improve the field condition. The control device 45 controls the water temperature in the field. In this case, at least the water supply unit 105 is controlled to adjust the timing of water supply to the field. In addition, when the correlation information indicates mid-drying or water fall, the control device 45 At the very least, by controlling the drainage unit 106, the drainage timing of the field is adjusted.

[0294] The control device 45 of the information processing device 33C detects that the target device TD related to the correlation information is the rice transplanter 1 If the correlation information is 0A, control information corresponding to the correlation information is output to the rice transplanter 10A.

[0295] The control device 45 of the information processing device 33C determines whether the target device TD related to the correlation information is a sprayer ( In the case where the control information is a spreader (multicopter 10B), the control information according to the correlation information is The output is sent to a drone (10B). The sprayer is a truck with a fertilizer or pesticide spraying device connected to it. It may be 10.

[0296] The control process of the target device TD based on the correlation information by the information processing device 33C of the second embodiment will be described with reference to Figs. 28A and 28B. Fig. 28A is a flowchart showing an example of the reflection process of the control information according to the correlation information of the second embodiment. Fig. 28B is a flowchart showing an example of the execution process of the cultivation plan after the reflection process shown in Fig. 28A. Since S1 to S5 shown in Fig. 28A are the same as Fig. 19B, S6 and subsequent steps shown in Fig. 28A will be described in detail.

[0297] The control device 45 of the information processing device 33C identifies the target device TD and the control information according to the correlation information (S6). Fig. 29 is a diagram showing an example of a correspondence table showing the correspondence between the correlation information, the target device, the control target, and the control information. As shown in Fig. 29, the storage device 46 stores in advance a correspondence table TB1 showing the correspondence between the correlation information, the target device TD, the control target, and the control information (adjustment or change content).

[0298] Correlation information (water temperature), target device TD (water management device 100), control object (water supply unit 105 and drainage unit 106), and control information (adjusting water temperature in the field) are stored in correspondence with each other in the correspondence table TB1. Correlation information (water temperature in the ripening period), target device TD (water management device 100), control object (water supply unit 105 and drainage unit 106), and control information (adjusting water temperature in the ripening period) are also stored in correspondence with each other in the correspondence table TB1. Correlation information (time to transplant seedlings), target device TD (water management device 100), control object (at least water supply unit 105), and control information (adjusting water supply time in the field) are also stored in correspondence with each other in the correspondence table TB1. Furthermore, the correspondence table TB1 stores correlation information (intermediate drainage or water drainage), target device TD (water management device 100), control target (at least drainage section 106), and control information (adjusting the drainage timing of the field) in association with each other.

[0299] Correlation information (rice planting date), target device TD (rice transplanter 10A), control object (rice transplanter 10A), and control information (adjusting the rice planting date) are stored in correspondence with each other in the correspondence table TB1. Correlation information (high temperature during rice planting season), target device TD (rice transplanter 10A), control object (none), and control information (change to high temperature variety) are stored in correspondence with each other in the correspondence table TB1. Correlation information (low water level during rice planting season), target device TD (rice transplanter 10A), control object (seedling planting device equipped in rice transplanter 10A), and control information (change from direct seeding by the direct seeding device to transplanting by the seedling planting device) are stored in correspondence with each other in the correspondence table TB1. In addition, the correspondence table TB1 stores correlation information (distance between rows), a target device TD (rice transplanter 10A), a control object (a seedling planting device provided in the rice transplanter 10A), and control information (adjusting the spacing between rows by the seedling planting device) in correspondence with each other.

[0300] Correlation table TB1 stores correlation information (fertilization date), target device TD (sprayer: fertilizer spraying device of multicopter 10B or tractor 10), control target (sprayer), and control information (adjustment of fertilization date) in association with each other. Correlation table TB1 also stores correlation information (pest control date), target device TD (sprayer: pesticide spraying device of multicopter 10B or tractor 10), control target (sprayer), and control information (adjustment of pest control date) in association with each other. Control information, other than "changing to a high temperature variety" and "changing from direct seeding to transplanting", is control information with contents that correspond to those of a good field.

[0301] For example, suppose that the two pieces of correlation information identified in S6 are "interim drainage" and "water temperature during ripening". Suppose that the degree of influence of "interim drainage" is "medium" and the degree of influence of "water temperature during ripening" is "large". If the identified correlation information is "interim drainage", the "water temperature during ripening" control device 45 can specify, by the correspondence relationship table TB1, that the target device TD is the water management device 100, that the specific control target is "at least the drainage unit 106", and that the control information is "adjustment of the drainage timing of the field". This control information of "adjustment of the drainage timing of the field" is the same as the control information of the drainage unit 106 of the interim drainage of the good field, in order to match the drainage timing of the interim drainage of the bad field with that of the good field.

[0302] Furthermore, if the identified correlation information is "water temperature during the ripening period," the control device 45 can identify, using the correspondence relationship table TB1, that the target device TD is the water management device 100, that the specific control target is the "water supply unit 105 and drainage unit 106," and that the control information is "adjustment of water temperature during the ripening period." This control information for "adjustment of water temperature during the ripening period" is control information for the water temperature during the ripening period of a bad field that has the same content as the control content of the water supply unit 105 and drainage unit 106 during the ripening period of a good field, in order to match the water temperature during the ripening period of a bad field to the water temperature during the ripening period of a good field.

[0303] After S6, the control device 45 displays a confirmation screen on the terminal device 33B indicating whether or not to reflect the information in the cultivation plan for the next agricultural season, and judges whether or not the information is reflected (S7). For example, the control device 45 displays the identified correlation information on the confirmation screen of the terminal device 33B in descending order of influence. Here, it is assumed that the identified correlation information is displayed on the terminal device 33B as "water temperature during the ripening period." When a button "reflect" is pressed on the terminal device 33B, the control device 45 judges that the information is reflected (Yes in S7), stores the "water temperature during the ripening period" in the cultivation plan for the next agricultural season of the bad field as adjusted (adjustment flag is turned on), and stores the same control information as the control information for the water temperature during the ripening period of the good field in the storage device 46.

[0304] On the other hand, in S7, if a button operation for "not reflecting" is performed on the terminal device 33B, the control device 45 determines that the information is not reflected (No in S7), and determines whether or not there is the next correlation information (S8).

[0305] The control device 45 judges whether or not there is the next correlation information (S8). Here, the identified correlation information is "intermediate drainage" with a "medium" impact level, so it is judged that there is the next correlation information (Yes in S8) and the process returns to S6. The control device 45 then identifies the target device TD and control information corresponding to the next correlation information (S6) and judges whether or not to reflect the information in the cropping plan for the next farming season (S7). When the "reflect" button is pressed on the terminal device 33B, the control device 45 judges that the information is reflected (Yes in S7), stores the "intermediate drainage" in the cropping plan for the next farming season of the bad field as adjusted (sets the adjustment flag on), and stores the information in the storage device 46 with the same control information as the control information for the drainage period of the intermediate drainage of the good field.

[0306] When the control device 45 determines that there is next correlation information (Yes in S8), on the other hand, when the control device 45 determines that there is no next correlation information (No in S8), this process ends.

[0307] As shown in FIG. 28B, when the next crop plan for the unsuitable field is executed, the control device 45 of the information processing device 33C judges whether it is the output timing of the specified control information (S11). For example, when the "intermediate drainage" in the crop plan for the next agricultural season for the unsuitable field is stored as adjusted (adjustment flag is turned on) and stored in the storage device 46 with the same control information as the control information for the drainage period of the intermediate drainage of the good field, the control device 45 judges whether it is "intermediate drainage". Also, when the "water temperature in the ripening period" in the crop plan for the next agricultural season for the unsuitable field is stored as adjusted (adjustment flag is turned on) and stored in the storage device 46 with the same control information as the control information for the water temperature in the ripening period of the good field, the control device 45 judges whether it is "ripening period".

[0308] If it is not the output timing of the specified control information (No in S11), the control device 45 returns to S11. For example, if it is not the "mid-drying" or "ripening period", the control device 45 returns to S11.

[0309] On the other hand, when it is the output timing of the specified control information (Yes in S11), the control device 45 outputs the control information to the target device TD (S12). For example, when it is "intermediate drainage", the control device 45 outputs to the water management device 100 of the unsuitable field the same control information as the control information for the drainage period of intermediate drainage of a good field. Also, when it is "ripening period", the control device 45 outputs to the water management device 100 of the unsuitable field the same control information as the control information for the water temperature during the ripening period of a good field.

[0310] For example, the judgment unit 160B1 of the water management device 100 can judge the growth stage, such as the rooting stage, tillering stage, panicle differentiation stage, booting stage, flowering stage, and ripening stage, from the state of the crop U1 in the image captured by the observation camera 180 as described above. For this reason, when the water management device 100 of the bad field judges that the state of the crop U1 is in the ripening stage, it outputs an instruction signal indicating that it is in the ripening stage to the information processing device 33C. When the control device 45 of the information processing device 33C receives this instruction signal, it may judge that it is in the "ripening stage" and output the same control information as the control information of the water temperature in the ripening stage of the good field to the water management device 100 of the bad field.

[0311] During mid-drying, the water management device 100 of the bad field controls at least the drainage section 106 of the water management device 100 of the bad field based on control information from the control device 45, and adjusts the drainage timing of the mid-drying of the bad field to match the drainage timing of the mid-drying of the good field. For example, the water supply section 105 of the water management device 100 of the bad field is left open and only the drainage section 106 is opened so that the mid-drying of the bad field is the same as the mid-drying of the good field last year or within a specified range.

[0312] For example, the judgment unit 160B1 of the water management device 100 can judge whether the crop U1 is deep water, shallow water, intermittent, mid-drainage, intermittent, low temperature irrigation, shallow water, intermittent, or drainage from the state (e.g., size) of the crop U1 in the image captured by the observation camera 180 as described above. For this reason, when the water management device 100 of the bad field judges that the state of the crop U1 is mid-drainage, it outputs an instruction signal indicating mid-drainage to the information processing device 33C. When the control device 45 of the information processing device 33C receives this instruction signal, it may judge that the crop U1 is "mid-drainage" and output to the water management device 100 of the bad field the same control information as the control information for the drainage period of mid-drainage in the good field.

[0313] 18E, the control device 160 stores, in order from the transplantation of seedlings, periods (water management periods) corresponding to deep water, shallow water, intermittent, mid-drying, intermittent, low temperature irrigation, shallow water, intermittent, and drainage, as water management for the field. Therefore, if the water management device 100 is in irrigation mode, it may determine that mid-drying is in progress based on this stored data, and output an instruction signal indicating that mid-drying is in progress to the information processing device 33C.

[0314] The control device 45 determines whether or not there is next specified control information (S13). If there is next specified control information (Yes in S13), the control device 45 returns to S11. If it is time to output the next specified control information, the control device 45 outputs the control information to the target device TD (S12).

[0315] During the ripening period, the water management device 100 of the bad field controls the water supply unit 105 and the drainage unit 106 of the water management device 100 of the bad field based on control information from the control device 45 to adjust the water temperature during the ripening period of the bad field to match the water temperature during the ripening period of the good field. For example, the water supply unit 105 and the drainage unit 106 of the water management device 100 of the bad field are opened so that the water temperature of the bad field is the same as the water temperature of the good field last year or within a predetermined range of difference.

[0316] For example, if there is no next specified control information (No in S13), the control device 45 ends this process.

[0317] Furthermore, the control device 45 of the information processing device 33C can cause the terminal device 33B to display a comparison result screen M9 including an annual comparison table for fields in which agricultural work has been changed using control information corresponding to the correlation information. Fig. 30 is a diagram showing an example of a screen display of the terminal device.

[0318] The comparison result screen M9 shown in FIG. 30 shows, for example, the results of discrimination between the year in which correlation information was acquired, i.e., "2020", the year before the farm work was changed, and "2021", the year in which the farm work was changed using control information corresponding to the correlation information, for a field with field number "E9". Stink bugs, burnt rice, white rice, product yield, and product yield are displayed for "2020" and "2021". The user can confirm that white rice in "2020" was "3.64", whereas in "2021" (i.e., the year in which the farm work was changed using control information corresponding to the correlation information), white rice has decreased to "2.31", and product yield and product yield have increased.

[0319] Furthermore, the control device 45 judges that there is an effect when the current value of the item indicated by the correlation information is lower than the previous value by a certain amount, and judges that there is no effect when this is not the case. Since the control device 45 judges that there is an effect, it displays a message MS9 indicating confirmation of the effect, such as "It seems that the change in the farm work based on the correlation information was effective," on the comparison result screen M9. Therefore, the user can confirm the effect of the change in the farm work based on the correlation information.
