In order to realize more precise and efficient agriculture, it is necessary to divide the field into small sections and perform appropriate farm work (referred to as a farm work event in the present application) for each small section. That is, the content of the farm work event carried out on the micro plot during cultivation (for example, the content of fertilization work), the content of the farm work event acquired in the micro plot at the time of harvest (for example, the amount and taste of the harvested crop). And, based on this record, determine the content of the next agricultural work event (for example, the content of fertilization work). However, for micro-compartments with special circumstances, simply mechanically obtaining the contents of agricultural work events (for example, the amount of fertilizer in fertilizer application work) for the next micro-compartment based on the yield and taste of the past micro-compartments. Therefore, there is a possibility of assigning inappropriate agricultural work event contents. In addition, since the experience of farmers is important in agriculture, it is more precise to consider various circumstances in a specific section and the experience of farmers when deciding the content of farm work for a small section. It is important to realize efficient agriculture.
In view of these circumstances, when planning a farm work event for a small plot, a farming system that can consider not only the contents of past farm work events but also the special circumstances of a specific micro plot and the experience of a farm worker is required. There is.

The farming system for managing a field divided into a plurality of micro-compartments according to the present invention includes a farm work event management unit that manages event results for each micro-compartment in various farm work events carried out on the field.

The outline of the farming system according to the present invention will be described with reference to FIG. The farming system described here is an example used for rice cultivation, but various crops such as wheat, corn, carrots, and onions can be handled in the same manner. This farming system is a computer system 5 provided with a layered database as a data recording unit 60. The computer system 5 is installed in a management center in which many farmers are registered and participating, and each farmer can access the computer system 5 by using a communication line such as the Internet. In the data recording unit 60, a layer that divides the field contour generated based on the field map data into a plurality of minute sections is used for each type of farm work event carried out for this field, and the field environment related to this field. Created for each type of information. Here, 5 m × 5 m is adopted as the size of the minute section, but other sizes may be adopted, or different sizes may be adopted depending on the agricultural work event. Since the position data corresponding to the map coordinates is assigned to the minute sections, each minute section can be specified by the position on the map. Further, although not shown in FIG. 1, a layer for recording the field environment information for each type is created for each measurement time of the field environment information. That is, the data recording unit 60 also records the history of agricultural work events and field environment information.

Examples of the agricultural work event recorded in the layer of the data recording unit 60 include rice planting work, fertilization work (including topdressing work), drug application work, water management work, growth status monitoring work, harvesting work, quality evaluation work, and the like. As a result of the event obtained by carrying out the agricultural work event, in the fertilization work and the drug application work, the fertilizer application amount and the medicine for each minute section can be obtained, and in the quality evaluation work performed at the same time as the harvesting work and the harvesting work, each minute section is obtained. Yield and taste are obtained. If the properties of the crops obtained in the sorting work performed after harvesting are, for example, rice cultivation or wheat cultivation, the result of the color selection inspection (detection of colored grains and immature grains by stink bugs) is that of colored grains and immature grains. The occurrence status is recorded in large plot units of the field. The yield and taste of agricultural products such as grains may be measured as part of the post-harvest drying operation.

Regarding field environment information, crop growth status can be recorded in small plot units, but sunshine duration, rainfall, wind passage, field temperature, soil quality, soil depth, fertility, etc. can be recorded in large plot units. The field ambient temperature and water management status are recorded substantially on a field-by-field basis.

Further, although not shown in FIG. 1, a field map is recorded in the data recording unit 60 as a basic layer of the field. Further, as field attribute data, information on field ID, field name, field location, planting type (rice, wheat, corn, etc.), and information on varieties (xx Hikari, XX Komachi, etc.) are also recorded.

The fertilizer application / medicine machine 1F, the drone 1D that examines the growth of seedlings and rice ears from the sky, and the harvester 1C that performs grain harvesting work are taken up. These agricultural work machines are equipped with a self-position detection device based on GNSS (Global Positioning Satellite System such as GPS), and can relate the detected running position (or flight position) to the event result. Various data generated by the agricultural work machine 1 can be sent to the computer system 5 in which the data recording unit 60 is constructed through a wireless data transmission device, a portable memory device, or the like.

In FIG. 1, as an example of the layer created in the data recording unit 60, a taste layer, a yield layer, a work route layer, a fertilization layer, a growth state layer, a soil fertility layer, a soil quality layer, and a soil depth layer are illustrated. There is. The computer system 5 is constructed with a farm work event management unit 61 and a field environment information management unit 62 that manage event results in units of minute sections in various farm work events carried out on the field. The farm work event management unit 61 can manage farm work events by using a layer assigned for each type of farm work event and for each implementation date and time. At that time, the agricultural work event management unit 61 records and manages the data related to the minute divisions sent from the agricultural work machine 1 in the matching layer. The field environment information management unit 62 manages the field environment information by using a layer assigned to each type of the field environment information and each time the field environment information is acquired. For example, the field environment information management unit 62 records and manages the field environment information sent from the agricultural work machine 1 and the measuring device (not shown) or the artificially created field environment information in a suitable layer. At that time, if the field environment information is related to the minute section, it is recorded in relation to the minute section.

In the work path layer, a work path, which is a traveling locus calculated from the position of the own machine acquired over time by the position detection device of the own machine, is recorded. For example, the work route of the rice planting / sowing machine 1P can be used to create a traveling route of the fertilizer application / medicine machine 1F and the harvester 1C thereafter.

FIG. 2 shows a functional block of the computer system 5 of the management center used in this embodiment. The computer system 5 receives the event results of the farm work events carried out by each of the control units 10 of the farm work machine 1, the tractor 1T, the rice planting / seeding machine 1P, the fertilizer application / medicine machine 1F, the drone 1D, and the harvester 1C. to manage.

The computer system 5 includes a user interface management unit 50, an information input unit 51, an information output unit 52, a data recording unit 60, an agricultural work event management unit 61, a field environment information management unit 62, an agricultural work event planning unit 63, and an event content correction unit 64. , The control information output unit 65 is provided. The information input unit 51 inputs information sent via a WAN such as the Internet, and the information output unit 52 inputs information generated by the computer system 5 to the agricultural work machine 1 or the user via the WAN such as the Internet. Send to the terminal UT. The user interface management unit 50 has a function of generating and managing a user interface screen such as a homepage in a cloud service system, a server client system, or the like, and is connected to various external terminals including the control unit 10 of the agricultural work machine 1.

The data recording unit 60, the agricultural work event management unit 61, and the field environment information management unit 62 have the functions described with reference to FIG. When the farm work event is carried out, the data such as the farm work event managed by the farm work event management unit 61 and the event result managed by the field environment information management unit 62 is stored in the data recording unit for each minute section of the field where the farm work event is carried out. Recorded at 60. In other words, the data is managed in a two-dimensional spread and a temporal spread.

The farm work event planning unit 63 calculates the content of the recommended event for each minute section in the farm work event carried out for the field by each farm work machine 1 based on the past event results extracted from the data recording unit 60. The content of the recommended event differs depending on the agricultural work event. For example, in the fertilizer application work, the fertilizer dose per micro-compartment is used. For this reason, the fertilizer application / medicine machine 1F has an adjustable fertilizer dose for each micro-compartment and has a self-position detection function by GNSS, and fertilizer is administered at the fertilizer dose assigned to each micro-compartment. Can be done. The fertilizer dose per micro-compartment in the content of the recommended event is calculated based on the past yield per micro-compartment and field environment information.

When the agricultural work event planning unit 63 uses the event results over a plurality of years and the field environment information as the input data for outputting the recommended event contents regarding the fertilizer application amount and the dosage amount, the input data amount becomes large. In order to obtain the desired output from a large number of input data of different types, the agricultural work event planning unit 63 includes a machine learning module.

The output of the recommended event content by the farm work event planning unit 63 is executed by the request through the user terminal UT owned by each farm. The output recommended event content is converted into a format visualized by the user terminal UT by the user interface management unit 50, and sent to the user terminal UT through the information output unit 52. On the user terminal UT side, the received recommendation event content is visualized by a monitor display or a printout. Farmers can formulate a final farm work plan while looking at the visualization of the recommended event content.

In order to examine the content of the recommended event, it is necessary to refer to the results of past farm work events carried out for the micro plots of the same field, so the results of such past farm work events can also be visualized in units of micro plots. It is sent to the user terminal UT in various formats. As a result of examining the content of the recommended event, if correction is necessary, the content of the recommended event is corrected in units of minute sections by sending the correction information from the user terminal UT to the computer system 5 based on the user input. This correction process is performed by the event content correction unit 64. At that time, the event content correction unit 64 can also give the correction content to the machine learning module of the agricultural work event planning unit 63 as teacher data and reflect it in the output of the next recommended event content.

FIG. 3 shows a monitor screen MS in which the recommended event content and reference information are displayed side by side, which is used when examining the recommended event content and when modifying the recommended event content based on the farmer's experience. It is shown. At that time, the positional relationship of each other's minute sections is displayed in association with each other. In this example, as the content of the recommended event, the fertilizer application plan map is displayed in the lower right area of the monitor screen MS, and the fertilizer application map showing the results of the fertilizer application work carried out in the previous year is displayed in the reference information area at the lower left of the monitor screen MS. It is shown. In each case, the field is divided into 5m × 5m micro-compartments, and the shades of the micro-compartments indicate the fertilizer dose, and the darker the area, the higher the dose. In the upper area of the monitor screen MS, the map information that can be displayed in the reference information area is displayed as thumbnails. In this example, the taste map, yield map, soil quality map, and soil fertility map are displayed, but scrolling displays other information maps. By dragging and dropping the thumbnail-displayed information map to the reference information area, the information map desired by the user is enlarged and displayed in the reference information area.

If you want to modify the fertilizer application dose in the fertilizer application plan map, which is the content of the recommended event, on the monitor screen MS, select the modified micro-section and operate the plus button or minus button. When the correction is completed, the event content correction unit 64 records the corrected event content in the data recording unit 60 as the determination event content. In this embodiment, a control information output unit 65 is provided that converts and outputs control information in a format that can be used by the agricultural work machine 1 that implements the event content based on the content of the determination event. In this case, control information for realizing the dose in the minute section defined by the map coordinates is generated so that the fertilizer application machine 1F administers the fertilizer according to the content of the determined fertilizer application work, and the fertilizer application is performed. -Send to the control unit 10 on the 1st floor of the dispensing machine.

As described above, when each farmer makes a plan for a farm work event, he / she accesses the computer system 5, extracts the data recorded in the data recording unit 60, and obtains the farm work event result and the field environment information as a user. Display on the terminal UT. For example, when making a fertilization plan for a specific field, the taste, yield, soil (soil quality), fertility, soil depth, growth status, sunshine (sunshine hours), in each minute section of the field. It is possible to display and refer to the ventilation, color selection status, etc. on the screen. In addition, when making a slowdown plan, the growth status, pest damage status, soil temperature, integrated temperature, sunshine duration, precipitation status, sunshine (sunshine duration), ventilation, etc. in each minute section of the field are displayed on the screen. It can be displayed and referenced. In this way, various information is displayed in units of minute sections, so that a precise farming event can be planned. Further, instead of each farmer individually planning a farm work event, an agricultural consultant may access the computer system 5 on behalf of each farmer to plan a farm work event.

The farm work machine 1 that carries out the farm work event in the field is provided with a function of recording the farm work event result for each minute section and a function of directly or indirectly sending the recorded farm work event result to the computer system 5. ..

FIG. 4 is a functional block diagram showing a functional unit related to the present invention constructed in the control unit 10 of the harvester 1C as an example of the agricultural work machine 1 introduced in this farming system. The harvester 1C has a crawler-type traveling device 101, a working device 102 such as a harvesting device and a threshing device, a yield measuring device 103 for measuring the yield of harvested grains at the time of harvest, and a grain taste for measuring the taste of the grains at the time of harvesting. It is equipped with a taste measuring device 104 and a sensor group 105 for detecting the state of each device of the harvester.

The control unit 10 includes a traveling ECU 11 that controls the traveling device 101, a working ECU 12 that controls the working device 102, a device state detection ECU 13 that processes a detection signal from the sensor group 105, a GPS unit 14 that detects the position of the own machine, and a yield. A measurement ECU 15 for processing a measurement signal from the measurement device 103 and the taste measurement device 104 is provided. Further, the computer system 5 is provided with an information generation unit 2 and an information communication unit 16 in order to send the yield, taste and work route data for each minute section as a result of the agricultural work event. The work ECU 12, the device state detection ECU 13, the GPS unit 14, the measurement ECU 15, the information generation unit 2, and the information communication unit 16 are connected to each other via an in-vehicle LAN or other data transmission line.

The information generation unit 2 includes a work basic data generation unit 21, a traveling locus data generation unit 22, a yield data generation unit 31, a taste data generation unit 32, and a field work data generation unit 20. The work basic data generation unit 21 generates basic information of the carried out agricultural work such as the work content, the work date and time, the field ID of the work field, and the fuel consumption. The travel locus data generation unit 22 processes the position (positioning data) of the own machine acquired from the GPS unit 14 in a timely manner, and generates work route data indicating the travel locus during work. The yield data generation unit 31 generates yield data indicating the yield associated with the position of the own machine (map coordinates) based on the data from the yield measuring device 103. The taste data generation unit 32 generates taste data related to the position (map coordinates) of the own machine based on the data from the taste measurement device 104.

The field work data generation unit 20 generates agricultural work event data by combining the data generated by the work basic data generation unit 21, the travel locus data generation unit 22, the yield data generation unit 31, and the taste data generation unit 32. The generated agricultural work event data is sent to the computer system 5 via the information and communication unit 16.

FIG. 4 shows a functional block in which the harvester 1C is taken as an example of the agricultural work machine 1, but the other agricultural work machines 1 also have a similar configuration with respect to the information generation unit 2. For example, in the fertilizer application / application machine 1F shown in FIG. 5, a fertilizer application / application device is mounted as a working device 102, and in the information generation unit 2, fertilizer application is performed instead of the yield data generation unit 31 and the taste data generation unit 32. A data generation unit 33 and a drug administration data generation unit 34 are provided. The fertilizer application data generation unit 33 generates fertilizer application data indicating the fertilizer dose for each minute section, which is related to the position of the own machine (map coordinates). The drug administration data generation unit 34 generates drug administration data indicating the drug dose for each minute section, which is related to the position of the own machine (map coordinates).

FIG. 6 shows an example of agricultural work event data generated by the information generation unit 2 of the harvester 1C and sent to the computer system 5. This farm work event data includes "field ID", "field name", "area", "region", "planting type", "variety", etc. as field basic information, and further, this field and harvester. It also contains micro-compartment data for the micro-compartments set for 1C. The micro-partition data includes a "micro-partition ID" and a "coordinate value". The "coordinate value" is a map coordinate value that defines the position of each minute section ID (either an absolute map coordinate value or a map coordinate value having a specific point of this field as the origin). The data showing the result of the farm work event of the harvester 1C is linked to the ID of the harvester 1C, and is linked to the "work content", "date and time of implementation", "working time", "fuel consumption", "working route", and " It includes a basic work data group such as "agricultural crop type" and a work record data group of "yield" and "taste" linked to "micro plot ID".

FIG. 7 shows an example of agricultural work event data generated by the information generation unit 2 on the fertilizer application / drug application machine 1F and sent to the computer system 5 during the fertilizer application work and the drug administration work. The basic work data group of the field basic information and the farm work event result is substantially the same as that of the harvester 1C except that the "fertilizer type" is included instead of the "crop type". The work performance data group includes the "fertilizer dose" linked to the "microcompartment ID".

In the above example, the micro-compartment is set before the implementation of the farm work event, and the result of the farm work event is assigned to the micro-compartment in the farm work machine 1. Instead of this, it is also possible for the computer system 5 side to allocate the result of the farm work event to a small area. In that case, in the farm work machine 1, the result of the farm work event is linked to the position (map coordinates) of the own machine from the GPS unit 14 and converted into data. Upon receiving such farm work event data, the farm work event management unit 61 of the computer system 5 displays the farm work event results (yield, taste, fertilizer drop amount, drug dose, etc.) linked to the map coordinates in the field in a predetermined size. Is assigned to the minute divisions obtained by dividing the data, and the data is recorded in the corresponding layer of the data recording unit 60.

The field environment information is not generated by the normal farm work machine 1, but the measurement data from the water management device and the environment measurement device installed in the field, the data downloaded from the server of the external organization, and the farmer's own acquisition. The measured data etc. Data that cannot be recorded in small plot units similar to the results of agricultural work events are recorded in field units or large plot units.
