Description

Technical Field

[0001] The present invention relates to an agricultural management system capable of managing various data in a farmland.

Background Art

[0002] Conventionally, there has been an agricultural management system that can display and output the location information of a farmland and the processing information of agricultural products together with map information for easy confirmation. For example, Patent Document 1 discloses an agricultural management system having a management means for managing the information of a farmland and the processing information of agricultural products harvested in the farmland, and a display unit connected to the management means and capable of displaying and outputting the processing information. The display unit can display and output the location of the farmland and the processing information together with the map information in a single pin display.

[0003] With such a configuration, even in a small-scale farmland where agricultural land and residential land are mixed, it is possible for a user to efficiently grasp the location of the farmland and the processing information. On the other hand, the displayed processing information is limited to the yield of the farmland and / or the quality information of the agricultural products harvested in the farmland. Therefore, although it is possible to manage the data related to the harvested agricultural products, there is no function to manage the information related to the farmland in the growth stage before harvesting, and it cannot be said to be sufficient as an agricultural management system.

Modes for Carrying Out the Invention

[0020] Hereinafter, embodiments of the agricultural management system of the present invention will be described with reference to the drawings. The agricultural management system of the present invention can be applied to agriculture for cultivating various agricultural crops such as fruits, mushrooms, vegetables, grains, etc. In this specification, the case where rice is the target agricultural crop will be described.

[0021] FIG. 1 is a system schematic diagram of the agricultural management system 1 of this embodiment. That is, the agricultural management system 1 of this embodiment includes at least a management device 2 and an operation terminal 3 connected to each other by a communication line including an Internet line or the like.

[0022] The management device 2 of this embodiment includes a database 20, a weather information acquisition means 21, a calculation means 22, a learning unit 23, a comparison means 24, and a management device transmission / reception unit 25.

[0023] The database 20 stores the location information (coordinates) of the fields managed by the agricultural management system 1, the processing results obtained by the processing of the weather information acquisition means 21, the calculation means 22, the learning unit 23, and the comparison means 24, and the information transmitted from the operation terminal 3.

[0024] The weather information acquisition means 21 acquires the weather information of the location closest to the location information of the fields managed by the agricultural management system 1 from the weather information management server 4. The weather information to be acquired includes location information such as latitude and longitude, and there are daily average temperature, daily maximum temperature, daily minimum temperature, daily accumulated precipitation, sunshine duration, all-day solar radiation amount, downward long-wave radiation amount, daily average relative humidity, daily average wind speed, etc.

[0025] As the weather information management server 4 for acquiring weather information, it is possible to use WAGRI, etc. of the National Agriculture and Food Research Organization, which divides the target area of weather observation into 1 km square grids and provides the weather information of each grid.

[0026] In the calculation means 22, the weather information acquired by the weather information acquisition means 21 is sent, and for each field managed by the agricultural management system 1, the accumulated temperature (the accumulated value of the daily average temperature) and the accumulated sunshine duration (the accumulated value of the daily sunshine duration) from the input reference date (accumulation start date) are calculated. When the agricultural crop is rice, the reference date (accumulation start date) input and set can be the heading date.

[0027] In this embodiment, when four pieces of weather information correspond to the weather information of the location closest to the location information of the field, that is, when the field is located at the corner of four grids, the average value of the four pieces of weather information is adopted.

[0028] In addition, when two pieces of meteorological information correspond to the meteorological information at the position closest to the field location information, that is, when the field is located at the boundary of two grids, the average value of the two pieces of meteorological information is adopted.

[0029] The learning unit 23 can use the harvested fields, crop varieties, accumulated temperature, and accumulated sunshine hours as teacher data to predict the optimal harvest time. In addition, it is also possible to use past harvest information such as the quality information and yield of the shipped agricultural products as teacher data. Based on the inference model of such a learning unit 23, the calculation means 22 can calculate the target accumulated temperature and target accumulated sunshine hours from the start date of accumulation (reference date) to harvest for harvesting a large amount of high-quality agricultural products.

[0030] The comparison means 24 compares the accumulated temperature and accumulated sunshine hours calculated by the calculation means 22 with the target accumulated temperature and target accumulated sunshine hours by the inference model constructed by the learning unit 23, and calculates the ratio of the accumulated temperature to the target accumulated temperature and the ratio of the accumulated sunshine hours to the target accumulated sunshine hours. Note that in the above comparison means 24, not only the target accumulated temperature and target accumulated sunshine hours by the inference model constructed by the learning unit 23, but also the target accumulated temperature and target accumulated sunshine hours determined in advance by the user may be compared with the accumulated temperature and accumulated sunshine hours calculated by the calculation means 22.

[0031] Then, the comparison means 24 determines whether the calculated ratio has reached 100%, is less than 100% and equal to or greater than a preset predetermined ratio (80% in this embodiment), or has not reached the predetermined ratio.

[0032] The management device transceiver unit 25 can transmit and receive various information to and from the operation terminal 3, and can further receive meteorological information from the meteorological information management server 4 and processing information from the preparation facility 5.

[0033] The operation terminal 3 can be a fixed terminal such as a personal computer, a tablet, a smartphone, a PDA, or other portable terminals.

[0034] As shown in FIG. 1, the operation terminal 3 includes at least an input unit 30, a display unit 31 such as a liquid crystal display, and an operation terminal transceiver unit 32 capable of transmitting and receiving information to and from the management device transceiver unit 25 of the management device 2, and an output information generation unit 33 that generates output information to the display unit 31 based on the information acquired from the management device 2.

[0035] The input unit 30 is used to input the position information of each farmland, the reference date (e.g., the heading date of rice), the variety of crops, the instruction information to the management device 2, etc. In addition, when there are the target accumulated temperature and the target accumulated sunshine hours determined by the user in advance as described above, the input unit 30 inputs these target accumulated temperature and target accumulated sunshine hours. The information input by the input unit 30 is transmitted to the management device transceiver unit 25 of the management device 2 via the operation terminal transceiver unit 32. The operation terminal transceiver unit 32 receives information such as the accumulated temperature and the accumulated sunshine hours transmitted from the management device transceiver unit 25.

[0036] In this embodiment, the agricultural management system 1 can at least execute three modes: a "management support mode", a "learning mode", and a "harvest support mode", which will be described in detail below.

[0037] "Management support mode" ··· It is possible to perform assignment registration of each farmland for cultivating crops and the user who manages each farmland. As a result, the registered user can view the list of farmlands to be managed and use the functions of the agricultural management system 1, and can confirm the processing results by the management device 2 together with the map information by the operation terminal 3.

[0038] "Learning mode" ··· As described above, the learning unit 23 of the management device 2 outputs the target accumulated temperature and the target accumulated sunshine hours corresponding to the variety of crops and each farmland based on the inference model based on the accumulated temperature and the accumulated sunshine hours from the reference date (accumulation start date) to the harvest of the crops and the harvest information such as the harvest amount and quality of the harvested crops.

[0039] "Harvest Support Mode" ··· A mode executed based on the processing results in the "Management Support Mode" and "Learning Mode". Based on the input information of the user who manages the farmland, it is possible to check the current accumulated temperature and accumulated sunshine hours in each farmland, and further confirm the appropriate harvest timing.

[0040] Hereinafter, an example of the operation mode of the agricultural management system 1 in the present embodiment will be described.

[0041] When the user logs in to the agricultural management system 1, a TOP screen as shown in FIG. 3 is displayed on the operation terminal 3. Then, when the user performs a menu operation, a setting screen as shown in FIG. 2 is displayed on the operation terminal 3.

[0042] On the setting screen shown in FIG. 2, it is possible to set the farmland to be managed. By touching the "Add" icon on the screen, a farmland selection screen as shown in FIG. 4 is displayed on the operation terminal 3. As shown in the figure, on the farmland selection screen, a plurality of farmlands are displayed by pin information PN together with map information. Then, by touching the pin information PN of the farmland to be managed and then touching the "OK" icon, the farmland can be set as the management target.

[0043] When the "OK" icon in FIG. 4 is touched, the setting screen shown in FIG. 2 is displayed again on the operation terminal 3. In FIG. 2, the farmland selected on the farmland selection screen is displayed as the farmland name "N20", and the lot number of the farmland is displayed. Then, the user can input the cultivated variety of the agricultural crop (for example, "Koshihikari", etc.) and the start date of accumulation through the input unit 30 of the operation terminal 3. Of course, the user may first input the location information of the farmland and the cultivated variety of the agricultural crop, and then input the start date of accumulation after the heading. When the "Back" icon on the farmland selection screen in FIG. 4 is touched, the screen returns to the setting screen in FIG. 2 without selecting a farmland.

[0044] When touching the "Delete" icon on the setting screen shown in FIG. 2, the target field can be removed from the management target and deleted from the list. Also, by checking the checkbox of "Top Display", as shown in FIG. 3, the weather information widget WG in the field to be checked is displayed on the TOP screen. As a result, since the integrated temperature and integrated sunshine hours of the fields checked at the time of application startup can be confirmed, it becomes possible to immediately check the weather information of the fields that need to be checked more carefully. Furthermore, when touching the "Details" icon of the weather information widget WG displayed on the TOP screen, the setting screen on which the information of each field shown in FIG. 2 is displayed is transitioned to.

[0045] When the integrated start date is input on the setting screen shown in FIG. 2, the calculation means 22 of the management device 2 calculates and displays the integrated air temperature and integrated sunshine hours from the integrated start date based on the weather information corresponding to the position of the field acquired by the weather information acquisition means 21, as shown in FIG. 2. Also, the target integrated air temperature and the target integrated sunshine hours (not shown) may be set to display the values predicted by the learning unit 23 as described above, or it is also possible for the user to directly input the target integrated air temperature and target integrated sunshine hours determined in advance.

[0046] Further, the comparison means 24 calculates the ratio of the integrated air temperature and integrated sunshine hours calculated by the calculation means 22 to the target integrated air temperature and target integrated sunshine hours, and determines whether the calculated ratio has reached 100% or a predetermined ratio.

[0047] When performing display output on the setting screen shown in FIG. 2, there are cases where the integrated air temperature and integrated sunshine hours have reached the target integrated air temperature and target integrated sunshine hours respectively, cases where the integrated air temperature and integrated sunshine hours have not reached the target integrated air temperature and target integrated sunshine hours respectively but have reached a predetermined ratio, and cases where the integrated air temperature and integrated sunshine hours have not reached a predetermined ratio of the target integrated air temperature and target integrated sunshine hours respectively. In each case, the character colors for displaying the integrated air temperature and integrated sunshine hours are color-coded with different colors from each other.

[0048] For example, when the accumulated temperature and the accumulated sunshine hours are 100% or more of the target accumulated temperature and the target accumulated sunshine hours, the text colors of the above-mentioned accumulated temperature and the above-mentioned accumulated sunshine hours shall be red. Also, if the accumulated temperature and the accumulated sunshine hours are 80% or more and less than 100% of the target accumulated temperature and the target accumulated sunshine hours, the text colors of the above-mentioned accumulated temperature and the above-mentioned accumulated sunshine hours shall be yellow. Furthermore, if the accumulated temperature and the accumulated sunshine hours are less than 80% of the target accumulated temperature and the target accumulated sunshine hours, the text colors of the above-mentioned accumulated temperature and the above-mentioned accumulated sunshine hours shall be green.

[0049] That is, if the accumulated temperature and the accumulated sunshine hours are displayed in red, it can be determined that the crops planted in that field have passed the appropriate harvesting period. Also, since the accumulated temperature has a higher correlation with the appropriate harvesting period than the accumulated sunshine hours, when the accumulated temperature is displayed in red and the accumulated sunshine hours are displayed in yellow, the user may judge to harvest. Note that these text colors are merely examples and are not limited to text colors as long as they can be distinguished by different display modes.

[0050] Subsequently, the operation mode of the "Harvest Support Mode" will be described. On the TOP screen as shown in FIG. 3, by the user performing a menu operation, it is possible to transition to the "Harvest Support Mode" as shown in FIG. 5. Specifically, on the display unit 31 of the operation terminal 3, as display information DI, map information MP around the current position CL and pin information PN indicating the positions of each field are displayed together.

[0051] When the user touches and operates the pin information PN, as shown in FIG. 6, on the display unit 31, the accumulated temperature and the accumulated sunshine hours from the start date of accumulation and the crop variety planted in the field corresponding to the touched pin information PN are displayed and output as weather information widget WG. Note that the example shown in FIG. 6 corresponds to the weather information of the field name "A10" in the setting screen shown in FIG. 2, and since the accumulated temperature exceeds 100% of the target accumulated temperature, it is displayed in red as in the setting screen.

[0052] Also, when the "Details" icon of the weather information widget WG shown in FIG. 6 is touched, the setting screen on which the information of each field shown in FIG. 2 is displayed is transitioned. Thereby, it becomes possible to check the details of the weather information of the field designated by the user on the map. When the "Back" icon of the weather information widget WG shown in FIG. 6 is touched, the display screen of the "Harvest Support Mode" shown in FIG. 5 is returned to.

[0053] As described above, in the agricultural management system 1 of the present embodiment, various information can be input and output via the operation terminal 3, and information can be displayed and output on the display unit 31 of the operation terminal 3 in response to a user's request.

[0054] As shown in FIG. 7, in the agricultural management system 1 according to the present embodiment, the management device 2 and the operation terminal 3 are connected to each other wirelessly or by wire. Then, information input from the input unit 30 of the operation terminal 3 (such as field position information, user information, crop variety information, integrated start date (reference date) information, mode selection information, field selection information, etc.) is transmitted to the management device 2.

[0055] Note that the management device 2 may be installed in an agricultural-related facility or the like, or may use a cloud server. The input information TI input from the input unit 30 as described above is stored and saved in the database 20 in association with each field.

[0056] Request information RI requested by the user using the operation terminal 3 (for example, mode selection information or field selection information) is transmitted from the operation terminal transmission / reception unit 32 of the operation terminal 3 to the management device transmission / reception unit 25 of the management device 2. Then, the management device 2 extracts necessary information from the database 20 and transmits it to the operation terminal 3 as output information OI.

[0057] Then, the output information OI transmitted from the management device 2 is received by the operation terminal transmission / reception unit 32 of the operation terminal 3, and display information DI required by the user generated by the output information generation unit 33 is configured to be displayed and output on the display unit 31.

[0058] The database 20 stores information about the fields (such as user ID, coordinates, plot number, cultivated crop variety, etc.). As a result, on the operation terminal 3, as shown in FIGS. 4 and 5, pin information PN indicating the position of each field can be displayed together with the map information MP.

[0059] Also, the accumulated temperature and accumulated sunshine hours from the start date of accumulation (reference date), the target accumulated temperature and target accumulated sunshine hours, the ratio of the accumulated temperature and accumulated sunshine hours to the target accumulated temperature and target accumulated sunshine hours, etc. are associated with each field and stored in the database 20. Therefore, by touching the arbitrary pin information PN on the map displayed on the display unit 31 of the operation terminal 3 (see FIG. 5), the accumulated temperature and accumulated sunshine hours of the field where the pin information PN is displayed can be color-coded and displayed on the display unit 31 in the same manner as the setting screen in FIG. 2 (see FIG. 6).

[0060] The user can use their own smartphone or the like as the operation terminal 3 and install a computer program (application) for operating the agricultural management system 1. Alternatively, it may be possible to use a web application (web app) that can be operated from a web browser using the Internet.

[0061] After the crops are harvested, the harvested amount and quality of the harvested crops, and the accumulated temperature and accumulated sunshine hours from the start date of accumulation (reference date) to the harvest date are fed back to the learning unit 23, and the prediction accuracy of the appropriate harvest time can be further improved.

[0062] In the above embodiment, the integrated temperature and integrated sunshine duration are color-coded and displayed on the display unit 31 of the operation terminal 3. However, the pin information PN indicating the positions of the respective fields shown in FIG. 5 may be color-coded based on the ratios of the integrated temperature and integrated sunshine duration to the target integrated temperature and target integrated sunshine duration. By configuring in this way, it becomes possible to grasp the meteorological information of a plurality of surrounding fields on the map. In addition, when performing color-coded display of the pin information PN, since the correlation between the appropriate harvest period and the harvest quantity and quality of the agricultural crop is higher for the integrated temperature than for the integrated sunshine duration, the color-coding of the pin information PN may be performed based on the integrated temperature.

[0063] In the above embodiment, as shown in FIGS. 3 and 6, the meteorological information widget WG is displayed, and the integrated temperature, the integrated sunshine duration, and the crop variety to be planted are displayed and output. However, other information, such as the date of heading (start date of integration), the target integrated temperature and target integrated sunshine duration, the predicted appropriate harvest period (date, number of remaining days, etc.) may also be displayed together.

[0064] In the above embodiment, the integrated temperature and the integrated sunshine duration are displayed on the setting screen of FIG. 2 and the meteorological information widget WG of FIGS. 3 and 6. However, only the integrated temperature, which has a high correlation with the appropriate harvest period and the harvest quantity and quality of the agricultural crop, may be displayed. Of course, it is also possible to display only the integrated sunshine duration.

[0065] As described above, the embodiments and some modification examples of the present invention have been described. However, these descriptions are for facilitating the understanding of the present invention and do not limit the present invention. The present invention can be changed and improved without departing from its gist, and equivalents thereof are included in the present invention. Also, within the scope of solving at least a part of the above-described problems or achieving at least a part of the effects, combinations or omissions of the respective components described in the claims and the specification are possible.
