[0020] The field water management system, the field water management device, and the terminal device according to the present invention will be described below. [Configuration of the field water management system] As shown in Fig. 1, the field water management system 100 is a system in which a field management server 40 functioning as a field water management device, a terminal device 50 owned by a farmer who is the manager of each field, and water supply and drainage equipment are connected via the Internet 30, which is an example of an information and communication network. Note that the information and communication network is not limited to the Internet 30.

[0021] Each field 1 where rice cultivation is carried out is provided with water supply and drainage equipment such as a water supply device 12 that directs irrigation water flowing in a water supply pipe 10 to the field 1 via a water conduit 11, a drainage device 22 that drains the water in the field 1 to a drainage channel 20 via a discharge channel 21, and a water temperature and water level meter 2 that measures the water temperature and water level in the field 1.

[0022] The water supply device 12 and the drainage device 22 are communicatively connected to a field water management server 40 via the Internet 30, or, if necessary, via a repeater consisting of a wireless router 32 arranged near the field 1, to the field water management server 40 via the Internet 30. For example, when the LTE-M (Long Term Evolution for machine-type-communication) method, which is suitable for IOT communication, is adopted, a repeater is not required, whereas a Lora (Low Power Wide Area) method is adopted, a repeater is required.

[0023] The water temperature and water level measured by the water temperature and water level gauge 2 are transmitted to the field water management server 40 via the water supply device 12. The water temperature and water level gauge 2 may be configured to transmit to the field water management server 40 via the drainage device 22, or the water temperature and water level gauge 2 may be configured to directly communicate with the field water management server 40. The water temperature gauge and water level gauge may each be configured as separate sensors.

[0024] A portable terminal device such as a smartphone or a tablet computer is preferably used as the terminal device 50. Note that a desktop or laptop computer may also be used as the terminal device 50.

[0025] Taking rice cultivation as an example, it is necessary to variably adjust the water level in the field 1 according to each stage of rice cultivation, such as plowing, transplanting, rooting period, tillering period (early and late), panicle formation period, heading and flowering period, ripening period, etc. For this purpose, a field water management system 100 is utilized.

[0026] 2, the field water management server 40 is a computer system equipped with a CPU board and a memory board, and is configured with functional blocks that execute desired operations by executing a specific application program under the control of an OS installed in the memory mounted on the memory board. Specifically, the functional blocks are a field management unit 42, a map information acquisition unit 44, a location information management unit 46, and a storage unit 48.

[0027] The field management unit 42 is a functional block that manages field management information including a field ID that uniquely identifies each field 1, field identification information linked to the field ID, water supply and drainage equipment identification information that identifies the water supply and drainage equipment including the water supply equipment 12 and drainage equipment 22 installed in each field 1, and the water supply and drainage status of each field 1, and remotely controls the water supply and drainage equipment.

[0028] The field identification information includes the latitude and longitude indicating the location of the field 1, the address of the field 1, and manager information. Information indicating the water supply and drainage status of the field 1 includes the target water level, current water level, drainage water level, water temperature, water tap opening, etc. The field management information is stored in a memory unit 48 consisting of a section of memory mounted on a memory board.

[0029] The map information acquiring unit 44 is provided with an API (Application Programming Interface) for using a service provided by a map information providing server 60, which is a commercial map information providing device such as Google Maps. The map information acquiring unit 44 requests map information from the map information providing unit 62 based on information specifying the area, such as the address of each field, included in the field management information. The map information providing unit 62 transmits link information for accessing the map information managed by the map information managing unit 64 based on the request from the map information acquiring unit 44. The map information acquiring unit 44 stores the link information in the memory unit 48.

[0030] The map information acquisition unit 44 transmits the link information to the terminal device 50 based on a request from the terminal device 50, and thereby the map is displayed on the display unit of the terminal device 50. The position information management unit 46 acquires the identification information of the field 1 or the water supply and drainage equipment and their position information, i.e., latitude and longitude information, transmitted from the terminal device 50, and associates the information with the field specifying information and water supply and drainage equipment specifying information managed by the field management unit 42.

[0031] The terminal device 50 has the following functional blocks: a request processing unit 52, a display processing unit 54, a position identification processing unit 56, and a position information transmission unit 58. Similar to the field water management server 40, these functional blocks are realized by the CPU executing an application program under the control of the OS installed in the memory of the terminal device 50, and function as a browser that receives information transmitted from the field water management server 40, executes predetermined processing, and transmits necessary information to the field water management server 40.

[0032] The display processing unit 54 is a functional block that displays information about a specific field 1 and water supply and drainage equipment transmitted from the field management unit 42 of the field water management server 40 on the display unit, thereby displaying the management status of the field 1 so that the farmer who owns the terminal device 50 can understand it.

[0033] Furthermore, the display processing unit 54 is a functional block that acquires map information from the map information providing server 60 based on the link information transmitted from the map information acquisition unit 44, displays the map information on the display unit, and also displays the positions of the field and water supply and drainage equipment on the map, thereby enabling the farmer who owns the terminal device 50 to confirm the positions of the field and water supply and drainage equipment, and to specify the positions of the field and water supply and drainage equipment on the map. Specific display modes and position designation modes will be described later.

[0034] The location specification processing unit 56 is a functional block that executes a process of specifying and registering the location of the field and the location of the water supply and drainage equipment on the map displayed on the display unit by the display processing unit 54, that is, a process of associating the identification information of the field and the water supply and drainage equipment with any point (point specified by latitude and longitude) specified on the map. The location information transmission unit 58 is a functional block that transmits the latitude and longitude associated by the display processing unit 54 and the identification information of the field and the water supply and drainage equipment to the field water management server 40.

[0035] The request processing unit 52 requests management including water supply and drainage treatment for a specific field 1 identified by the field identification information. For example, when flooding control is performed, a target water level is specified and a water supply request is sent. In response to this request, the field management unit 42 operates the drainage device 22 of the corresponding field by specifying the height of the drainage weir that will be the drainage water level, and outputs a water supply command to the water supply device 12. The water supply device 12 controls the opening and closing of the water supply tap based on the value of the water temperature and water level gauge 2, and transmits the operating state of the water supply tap and the water temperature and water level of the field measured by the water temperature and water level gauge 2 to the field management unit 42.

[0036] Furthermore, the request processing unit 52 requests the field water management server 40 to register the position information of the field 1 and water supply and drainage appliances, and to update the registered position information to new positions.

[0037] The water supply device 12 includes a water supply faucet 12A and a water supply control device 12B. The water supply control device 12B includes an actuator 120 that operates the water supply faucet 12A, a water supply control unit 122 that controls the actuator 120, and a communication unit 124 that communicates with the field water management server 40. It also includes a storage battery 126 that supplies power to the motor provided in the actuator 120, the water supply control unit 122, the communication unit 124, etc., and a solar cell 128 that charges the storage battery 126.

[0038] The drainage device 22 includes a drainage weir 22A and a drainage control device 22B. The drainage control device 22B includes an actuator 220 that raises and lowers the drainage weir 22A, a drainage water level control unit 222 that controls the actuator 220, and a communication unit 224 that communicates with the field water management server 40. It also includes a storage battery 226 that supplies power to the motor provided in the actuator 220, the drainage water level control unit 222, the communication unit 224, etc., and a solar cell 228 that charges the storage battery 226. Note that the solar cells 128 and 228 are not essential.

[0039] FIG. 3 shows a series of water management processes executed by the field water management server 40. When a login request is received from any of the pre-registered terminal devices 50 (SA1), the field management unit 42 reads out management information of the field managed by the farmer who is the operator of the terminal device 50 from the storage unit and transmits it to the terminal device 50 (SA2). As a result, the management information of the field managed by the farmer is displayed on the display unit of the terminal device 50.

[0040] When a map display request is received from the terminal device 50 (SA3), the map information acquisition unit 44 acquires link information (map information) for accessing a map of the relevant area from the map information providing server 60 (SA4), and if there is location information of a preregistered farm field or water supply and drainage equipment, transmits the location information together with the link information to the terminal device 50 (SA5). As a result, map information including the farm field managed by the farmer is displayed on the display unit of the terminal device 50.

[0041] When location information of the field or water supply and drainage equipment is transmitted from the terminal device 50 (SA6), the location information management unit 46 stores the identification information of the field or water supply and drainage equipment and their location information (latitude and longitude information) in association with the field identification information and water supply and drainage equipment identification information managed by the field management unit 42 (SA7).

[0042] When a processing request for the field is made from the terminal device 50 (SA8), the field management unit 42 remotely controls the water supply and drainage equipment of the field, and updates and stores the state of the field, such as the water faucet opening, water level, water temperature, etc. (SA9). The processing from steps SA2 to SA9 is repeated until the terminal device 50 logs off, and when logged off, the processing waits in step SA1 (SA10).

[0043] FIG. 4 shows a series of processes executed by the terminal device 50 operated by the farmer. When a farmer logs in to the field water management server 40 (SB1), the display processing unit 54 acquires field management information about the field managed by the farmer, transmitted from the field water management server 40 (SB2), and displays the acquired management status of the field and water supply and drainage equipment on the display unit provided in the terminal device 50 (SB3). The field management information of the field managed by the farmer is associated with the login information.

[0044] If the farmer checks the display contents on the screen and performs some kind of touch operation (SB4, Y), and if the operation is an operation requesting the display of a map (SB5, Y), the request processing unit 52 sends a map display request to the field water management server 40 (SB6), obtains map information from the map information providing server 60 based on the link information sent from the field water management server, and displays the map on the display unit (SB7). If there is no operation in step SB4, a log-off check is performed in step SB10 (SB10), and if there is no log-off, the process returns to step SB2.

[0045] The map information displayed at this time is preferably an aerial photograph, but may be a topographical map. If a farm field or water supply and drainage equipment is associated with the latitude and longitude managed by the position information management unit 46, a label indicating the farm field or water supply and drainage equipment is displayed at the corresponding latitude and longitude position on the map.

[0046] When the farmer performs some kind of touch operation on the display screen and it becomes necessary to send some kind of request to the field water management server 40 (SB5, Y), a processing request is sent (SB9) to the field water management server 40. Processing requests include a request for remote control of water supply and drainage equipment for flooding and draining the field to be managed, a schedule setting request for water supply and drainage equipment for flooding and draining at a specified date and time, and a location information registration request for registering the installation positions of the field and water supply and drainage equipment on the displayed map.

[0047] Furthermore, in step SB10, it is determined whether or not the user is logged off (SB10), and the process returns to step SB2 until the user is logged off, and ends when the user is logged off. Also, if there is no processing request in the above-mentioned step SB8 (SB8, N), the process returns to step SB2.

[0048] 5 to 17 show screens that are displayed on the display unit of the terminal device 50 by the display processing unit 52. Reveal Note that the screen displays described below are examples for ease of understanding, and the displayed contents, such as specific numerical values, may not be realistic.

[0049] The login screen is shown in Figure 5(a). After logging in by entering a user name and password, the initial screen shown in Figure 5(b) is displayed. The initial screen is a field list screen that displays a list of the fields managed by the farmer. In this example, three fields managed by the farmer, Field 1, Field 2, and Field 3, are displayed, along with the water level, water temperature, water tap status, and drainage height (target height of the drainage dam) for each field. The field list screen allows the farmer to understand the status of each field. Several menus for switching display modes are displayed at the top of the screen.

[0050] When the display area for "Field 1" indicated by a thick line is touched on the "Field List" screen shown in FIG. 6(a), the screen switches to the "Field Details" screen shown in FIG. 6(b), where detailed information for field 1 is displayed. In this example, the values ​​of the water level and temperature gauges, the number of water supply devices and their status are displayed. When the display area for "Field List" indicated by a thick line is touched, the screen switches to the field list screen shown in FIG. 6(a). The display content of each screen is based on the field management information sent from the field management server 40.

[0051] 6(b), an operation screen is displayed for remotely controlling the water supply, drainage, and water level settings for the corresponding field in real time, and the water supply and drainage equipment for the corresponding field is remotely controlled by the field water management device 40 in accordance with the operations on the screen. Furthermore, when the "Schedule Setting" display area is touched, an operation screen is displayed for setting schedules for water supply and drainage for the corresponding field in the field water management server 40, and when the "Field Setting / Equipment Setting" display area is touched, an operation screen is displayed for setting information such as the specifications of the equipment installed in the corresponding field in the field water management server 40.

[0052] When the "Map Display" display area indicated by a thick line on the "Field List" screen shown in Fig. 7(a) is touched, a map (aerial photograph) of the area in which fields 1, 2, and 3 are located is displayed in the middle of the screen, as shown in Fig. 7(b), and the lower section displays management information for the fields included in the map, such as the field name, water level, water temperature, valve (water tap) opening, and communication repeaters to which the water supply and drainage equipment is connected. When the "Field List" display area indicated by a thick line on the "Map Display" screen in Fig. 7(b) is touched, the screen returns to the "Field List" screen shown in Fig. 7(a).

[0053] The map in question is a map acquired by the display processing unit 54 from the map information providing server 60 based on link information transmitted from the field water management server 40, i.e., link information previously associated with the map based on the addresses or latitude and longitude of the fields. The numbers 2 and 3 enclosed in circles shown on the map indicate field 2 and field 3, respectively. At this point, link information associating field 1 with the map has not been generated, so the number 1 enclosed in a circle is not displayed on the map.

[0054] When the display area for "Field 1" indicated by a thick line is touched on the "Map Display" screen shown in Figure 8(a), detailed field information such as the latest management information for Field 1, including water level, water temperature, valve opening, and drainage height (height of the drainage dam), is displayed, as shown in Figure 8(b).

[0055] When the "Location registration" display area indicated by a thick line is touched on the "Map display" screen shown in Fig. 9(a), the screen switches to a screen for registering "Field 1" on the map, as shown in Fig. 9(b), and the message "Please click on the location information to register" is displayed. When the "OK" display area is touched and the location of "Field 1" is touched on the map, a marker indicating the registration location is displayed, as shown in Fig. 10(a), and a confirmation message is displayed asking "Do you want to register at this location?", as shown in Fig. 10(b).

[0056] When the "OK" display area is touched on the screen in Fig. 10(b), a registration request is sent to the location information management unit 46 so as to associate the latitude and longitude of the map with the field 1, link information associating the latitude and longitude with the field 1 is generated, and the link information is incorporated into the field management information. As a result, as shown in Fig. 10(c), the number 1 enclosed in a circle is displayed on the map, making it possible to grasp the location of the field 1.

[0057] The "Map Display" screen shown in Fig. 11(a) displays detailed field information for Field 3. When the "Equipment Layout" display area indicated by the thick line in the lower right of this screen is touched, a list of water supply and drainage equipment installed in Field 3 is displayed, as shown in Fig. 11(b). Field 3 has two water supply devices and three drainage devices installed.

[0058] These water supply and drainage devices are not associated with the map, and therefore are not displayed on the map. When the display area for "Water Supply Device 3-1" indicated by a thick line on the "Map Display" screen shown in Fig. 12(a) is touched, detailed information for "Water Supply Device 3-1" is displayed as shown in Fig. 12(b). When the display area for "Location Information Registration" indicated by a thick line in Fig. 13(a) is touched, a message stating "Please click on the location information to register" is displayed as shown in Fig. 13(b).

For example, a message such as "Please check the capacity of the storage battery" installed in the water supply and drainage equipment is displayed.

[0062] As described above, the field water management system according to the present invention is a field water management system in which a field water management device and a terminal device are connected via an information and communication network, and the field water management device comprises a field management unit that manages field management information including a field ID that uniquely identifies each field, field identification information linked to the field ID, water supply and drainage equipment identification information that identifies water supply and drainage equipment installed in each field, and the water supply and drainage status of each field, and a map information acquisition unit that acquires map information of the area in which each field is located from a map information providing device. the terminal device is configured to include a display processing unit that acquires the field management information from the field water management device and displays the management status of a specific field on a display unit, and a display processing unit that superimposes position markers identifying the field and the water supply and drainage equipment on the map displayed on the display unit based on the map information and the position information acquired from the field water management device.

[0063] The terminal device is further configured to include a location identification processing unit that identifies the locations of the field and the water supply and drainage equipment on the map displayed on the display unit, and a location information transmission unit that transmits the location information of the field and the water supply and drainage equipment identified by the location identification processing unit to the field water management device, and the location information management unit provided in the field water management device is configured to update the location information transmitted from the location information transmission unit.

[0064] The field management information further includes status information for specifying whether the water supply and drainage equipment is normal or abnormal, and the display processing unit is configured to change the display mode of the position indicator based on the status information. Therefore, by visually checking the display mode of the position indicator for specifying the field and the water supply and drainage equipment superimposed on the map, it is possible to easily grasp whether the water supply and drainage equipment is normal or abnormal.

[0065] In the above explanation, the water supply and drainage equipment includes a water supply device, a drainage device, a water level sensor, a temperature sensor, and a communication repeater, but there are cases where each field does not have a remotely controllable drainage device or does not have a communication repeater. Therefore, the water supply and drainage equipment needs to include at least a water supply device and a water level sensor. In a field that does not have a remotely controllable drainage device, the farmer will manually adjust the height of the drainage dam installed in the field.

[0066] The embodiment described above is merely one example of the present invention, and the description is not intended to limit the technical scope of the present invention. It goes without saying that the specific configuration of each part can be appropriately modified and designed within the scope of the effect of the present invention. [Explanation of symbols]
