DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] A field water management system 10 according to one embodiment of the present invention will be described below.

[0027] The field water management system 10 is for managing the water supply and drainage of each field H. As shown in Fig. 1, the field water management system 10 includes a water supply device 11, a drainage device 12, a communication repeater 13, an owner terminal 14, and a field management server 15.

[0028] The water supply device 11 is for supplying water to the field H. The water supply device 11 is provided in each field H. The water supply device 11 includes a communication device for communicating with the communication repeater 13 described later, and a water supply valve provided in a waterway connecting the water supply pipe S and the field H (not shown). The water supply device 11 can control the start and stop of water supply from the water supply pipe S to the field H by opening and closing the water supply valve. The water supply device 11 can also adjust the amount of water supplied to the field H depending on the opening degree of the water supply valve. As shown in Figs. 1 and 2, the water supply device 11 includes a solar panel 11a, an operation unit 11b, a microphone 11c, a battery 11d, and a water supply control unit 11e.

[0029] The solar panel 11a is for generating power by utilizing sunlight. The solar panel 11a is provided on a housing that forms the outer periphery of the water supply device 11.

[0030] Operation unit 11b is for manually operating the water tap. Operation unit 11b is provided on the housing of water supply device 11. Operation unit 11b includes buttons for opening and closing the water tap, etc. As will be described later, in this embodiment, button operation of operation unit 11b is valid only when certain conditions are met. In this state, owner P of field H can manually open and close the water tap by operating the button on operation unit 11b.

[0031] 2 is for capturing a predetermined sound such as the voice of the owner P. The microphone 11c is provided inside the housing of the water supply device 11.

[0032] The battery 11d supplies the power used for the operation of the water supply device 11. The battery 11d is connected to the solar panel 11a and can be charged with the power generated by the solar panel 11a. For example, a lithium ion battery can be used as the battery 11d.

[0033] The water supply control unit 11e is a device for controlling the operation of the water supply device 11. The water supply control unit 11e is equipped with a calculation device, a storage device, etc., and can execute processes related to the operation of the water supply device 11. For example, the water supply control unit 11e can communicate with the farmland management server 15 via the communication repeater 13 described later, and can open and close the water tap in response to the operation of the operation unit 11b. The water supply control unit 11e can also acquire voice from the microphone 11c and execute various processes. The processes based on the voice from the microphone 11c will be described later.

[0034] The drainage device 12 shown in FIG. 1 and FIG. 2 is for draining the field H. The drainage device 12 is provided in each field H. The drainage device 12 includes a communication device for communicating with the communication repeater 13 and a lifting body provided at the drainage outlet of the field H (not shown). The drainage device 12 discharges the water in the field H that exceeds the lifting body into the drainage channel D. In this way, water can be stored in the field H up to a water level that is the same height as the height position (height position of the upper surface) of the lifting body. Hereinafter, such a height position of the lifting body (water level that can be stored in the field H) is referred to as the "drainage height". The drainage device 12 also includes a solar panel 12a, an operation unit 12b, a microphone 12c, a battery 12d, and a drainage control unit 12e.

[0035] Solar panel 12a, microphone 12c, and battery 12d are configured in the same manner as in water supply device 11. Operation unit 12b and drainage control unit 12e are configured in the same manner as in water supply device 11, except for adjusting the drainage height.

[0036] 1 is a device capable of wireless communication. The communication repeater 13 can exchange information with the water supply device 11, the drainage device 12, and the farm land management server 15 via wireless communication.

[0037] The owner terminal 14 is a terminal owned by the owner P of the field H. The owner terminal 14 is configured by a device (such as a smartphone or a tablet terminal) that the owner P can carry with him / her. The owner terminal 14 has a communication function and can exchange various information with external devices. As shown in Fig. 2, the owner terminal 14 includes a microphone 14a, a speaker 14b, a touch panel 14c, a position detection unit 14d, and a terminal control unit 14e.

[0038] The microphone 14a is for acquiring a predetermined sound such as the voice of the owner P. The speaker 14b is for outputting sound. The microphone 14a and the speaker 14b are built into the owner terminal 14.

[0039] The touch panel 14c is for inputting and outputting information. The touch panel 14c can display predetermined information. Various types of information are input to the touch panel 14c by touch operations.

[0040] The position detection unit 14d is for detecting position information (latitude, longitude, etc.) indicating the current position of the owner terminal 14. The position detection unit 14d can receive signals from GPS satellites and mobile phone base stations and detect the position information (latitude and longitude) of the owner terminal 14.

[0041] The terminal control unit 14e controls the owner terminal 14. The terminal control unit 14e is mainly composed of an arithmetic processing unit such as a CPU, a storage (storage device), and the like. The terminal control unit 14e can appropriately control devices provided in the owner terminal 14. For example, the terminal control unit 14e can output sound from the speaker 14b and display information on the touch panel 14c. In addition, various information is input to the terminal control unit 14e from devices provided in the owner terminal 14. Specifically, the terminal control unit 14e receives inputs of sound acquired by the microphone 14a, operation results on the touch panel 14c, and detection results of the position detection unit 14d. In addition, the terminal control unit 14e can execute various processes based on the sound from the microphone 14a. The process based on the sound from the microphone 14a will be described later.

[0042] 1 and 2 is for carrying out processes related to water supply and drainage in the field H. The field management server 15 is configured as a cloud server (strictly speaking, a server virtually constructed within the cloud server).

[0043] The farm field management server 15 configured as described above can exchange information with the water supply apparatus 11 and the drainage apparatus 12 (the water supply control unit 11e and the drainage control unit 12e) via the communication repeater 13. The farm field management server 15 can acquire various information by receiving signals from the water supply apparatus 11 and the drainage apparatus 12. For example, the farm field management server 15 can acquire the opening degree of the water supply faucet based on the signal from the water supply apparatus 11. The farm field management server 15 can also acquire the current drainage height based on the signal from the drainage apparatus 12.

[0044] Furthermore, the farm field management server 15 can control the water supply and drainage of the field H by sending signals to the water supply device 11 and the drainage device 12. For example, the farm field management server 15 can open and close the water supply tap by sending a signal to the water supply device 11. Furthermore, the farm field management server 15 can change the drainage height by sending a signal to the drainage device 12. The farm field management server 15 can adjust the water level of the field H to a height suitable for the growth conditions by automatically opening and closing the water supply tap and adjusting the drainage height based on the crop variety and growth conditions.

[0045] Furthermore, the farm land management server 15 can exchange information with the owner terminal 14 via an internet line or the like. For example, the farm land management server 15 can acquire the detection results of the position detection unit 14d from the owner terminal 14. Furthermore, the farm land management server 15 can operate the water supply device 11 and the drainage device 12 based on signals from the owner terminal 14.

[0046] The fields H to which the field water management system 10 configured as described above is applied are divided into field groups G. A field group G is a collection of fields H (see FIG. 4). A field group G includes at least one field H. The field groups G are set in advance and managed by a field management server 15. The field management server 15 can operate the water supply devices 11 and the drainage devices 12 for each field H or for each field group G. When a field H is provided with multiple water supply devices 11 and multiple drainage devices 12, the field management server 15 can operate one or more of the multiple devices, or can operate all of the devices collectively.

[0047] Furthermore, the farm land management server 15 can operate the water supply device 11 and the drainage device 12 based on voices picked up by the microphones 11c, 12c, and 14c of the water supply device 11, the drainage device 12, and the owner's terminal 14. First, the terminal side operation process for operating the water supply device 11, etc. based on voices picked up by the microphone 14a of the owner's terminal 14 will be described below.

[0048] 3 is executed when an appropriate operation is performed on the owner terminal 14. The terminal side operation process is executed when, for example, an application that executes the terminal side operation process is started on the owner terminal 14.

[0049] When the terminal side operation process is executed, the terminal control unit 14e performs the process of step S110. In step S110, the terminal control unit 14e performs voiceprint authentication of the owner P from the voice acquired by the microphone 14a of the owner terminal 14. Specifically, the terminal control unit 14e compares the voice characteristics included in the voice acquired by the microphone 14a with the voice characteristics of the owner P stored in advance. If these match, the terminal control unit 14e authenticates the owner P (step S110: Yes). In this case, the process of step S120 is performed. On the other hand, if the owner P cannot be authenticated (step S110: No), the terminal side operation process is terminated. In this way, by authenticating the owner P, the terminal control unit 14e can prohibit the operation of the water supply device 11 and the drainage device 12 by anyone other than the owner P, thereby improving security.

[0050] In step S120, the field management server 15 determines whether the owner P is near the water supply apparatus 11 or the drainage apparatus 12. Specifically, when the processing of step S120 is started, the owner terminal 14 transmits position information of the owner terminal 14 (detection result of the position detection unit 14d) to the field management server 15. Based on the position information of the owner terminal 14 and pre-stored position information of the water supply apparatus 11, etc., the field management server 15 extracts the apparatus located closest to the owner terminal 14 from among the water supply apparatuses 11 and drainage apparatuses 12 of each field H. Then, the field management server 15 determines whether the distance (e.g., straight-line distance) of the extracted apparatus to the owner terminal 14 is less than a predetermined threshold. In this way, the field management server 15 determines whether the owner P is located close enough to the water supply apparatus 11 or the drainage apparatus 12 to visually confirm the operation of the water supply apparatus 11 or the drainage apparatus 12.

[0051] If the distance to the owner terminal 14 is less than a predetermined threshold, the farm field management server 15 determines that the owner P is near the water supply apparatus 11, etc. (step S120: Yes). In this case, the process of step S140 is performed. On the other hand, if the distance to the owner terminal 14 is equal to or greater than a predetermined threshold, the farm field management server 15 determines that the owner P is not near the water supply apparatus 11, etc. (step S120: No). In this case, the process of step S130 is performed.

[0052] In step S130, the farm field management server 15 determines which of the water supply devices 11 and drainage devices 12 in each farm field H are to be operated, based on the input results to the owner terminal 14. In this way, the operation target is selected by the owner P. When the processing of step S130 is completed, the processing of step S160 is performed.

[0053] In step S140, the farm land management server 15 automatically determines the operation target based on the position information of the owner terminal 14. Specifically, the farm land management server 15 determines, as the operation target, the water supply device 11 and the drainage device 12 that is located closest to the owner terminal 14 (for example, the device with the shortest straight-line distance to the owner terminal 14). When the processing of step S140 ends, the processing of step S150 is performed.

[0054] In step S150, the farm land management server 15 determines the operation timing of the operation target based on the position information of the owner terminal 14. In this embodiment, the farm land management server 15 determines the time interval for communication between the operation target and the farm land management server 15. This will be described in detail below.

[0055] When the farm field management server 15 receives a signal from the owner terminal 14 to operate the water supply apparatus 11 and the drainage apparatus 12, it transmits a signal to the water supply apparatus 11, etc. to instruct the apparatus to operate. At this time, the farm field management server 15 does not transmit the signal to the water supply apparatus 11, etc. immediately upon receiving the signal from the owner terminal 14, but transmits the signal at regular intervals. By transmitting the signal at regular intervals in this manner, it is possible to reduce the processing load and power consumption. For example, in this embodiment, it is assumed that the time interval is set so that the farm field management server 15 and the water supply apparatus 11, etc. communicate every 10 minutes.

[0056] In step S150, farm field management server 15 changes the time interval for communicating with the operation target determined in step S140 to an interval (for example, every minute) shorter than the preset time interval (every 10 minutes). By changing it in this way, the timing of operation of water supplying apparatus 11 etc. in response to the transmission of a signal from owner terminal 14 to farm field management server 15 is changed. In other words, when a signal is transmitted from owner terminal 14 to farm field management server 15, water supplying apparatus 11 etc. will operate promptly (within one minute). When the processing of step S150 is completed, the processing of step S160 is performed.

[0057] In step S160, the farm land management server 15 operates the operation object determined in steps S130 and S140 in response to the owner P's speech. At this time, the terminal control unit 14e analyzes the voice acquired by the microphone 14a and outputs the voice contained in the voice as text information. The terminal control unit 14e extracts information indicating the operation content (opening degree, etc.) from the voice thus recognized (output text information) and transmits the extraction result to the farm land management server 15. The farm land management server 15 operates the operation object in response to the information. This allows the owner P to operate the water supply device 11 by speaking to the owner terminal 14. When the processing of step S160 ends, the terminal side operation processing ends.

[0058] A specific example of the terminal-side operation process will be described below with reference to Fig. 4. In this example, a field group G includes a first field H1, a second field H2, a third field H3, and a fourth field H4. In this example, an owner P who is in a location (e.g., at home) away from the fields H1 to H4 operates the water supply device 11 of the first field H1.

[0059] When the terminal operation process is started, the owner terminal 14 (terminal control unit 14e) authenticates the owner P based on the utterance of the owner P (for example, the utterance of "start operation") (Step S110: Yes).

[0060] Because the owner P (owner terminal 14) is located away from each of the fields H1 to H4 (step S120: No), the terminal control unit 14e issues a message prompting the owner P to select an operation target. For example, the terminal control unit 14e causes the speaker 14b or the touch panel 14c to output a message saying "Please specify the device to operate." When the owner P speaks in response to the message ("The water supply device of the first field"), the terminal control unit 14e recognizes the content of the speech and transmits it to the field management server 15. In this way, the field management server 15 determines the water supply device 11 of the first field H1 as the operation target based on the input result to the owner terminal 14 (step S130).

[0061] Then, the farm land management server 15 accepts the speech from the owner P. At this time, the terminal control unit 14e notifies the owner P of a message urging him / her to speak the operation content based on an instruction from the farm land management server 15. For example, the terminal control unit 14e causes the speaker 14b or the touch panel 14c to output a message saying "Please specify the operation."

[0062] When the owner P speaks in response to the message ("stop water supply"), the terminal control unit 14e recognizes the speech and extracts information indicating the operation content ("supply water" and "stop"). The terminal control unit 14e then notifies the user that the speech has been accepted. For example, the terminal control unit 14e causes the speaker 14b or the touch panel 14c to output a message saying "An instruction to stop water supply has been accepted." The terminal control unit 14e also transmits the extracted operation content to the field management server 15. The field management server 15 communicates with the water supply device 11 at appropriate timing based on a preset time interval (every 10 minutes) for communicating with the water supply device 11. At this time, the field management server 15 transmits a signal corresponding to the operation content from the terminal control unit 14e to the water supply device 11 of the first field H1, and stops the water supply to the first field H1 (step S160).

[0063] In this way, the owner P can operate the water supply apparatus 11 by speaking into the owner terminal 14. This allows the farm field management server 15 to reduce the burden of inputting information into the owner terminal 14 when the owner P operates the water supply apparatus 11. Furthermore, when the owner P is not near the water supply apparatus 11, the farm field management server 15 can set the time interval for communicating with the water supply apparatus 11 to be relatively long (for example, operating every 10 minutes), thereby reducing the processing load and power consumption.

[0064] Unlike this specific example, when the owner P specifies field group G as the target of operation (for example, when he / she speaks the name of field group G into the owner terminal 14), the field management server 15 stops water supply to each of the fields H1 to H4 belonging to the field group G.

[0065] Also, unlike this specific example, when the owner P speaks into the owner terminal 14 near the water supply apparatus 11 in the first field H1 (step S120: Yes), the field management server 15 determines the water supply apparatus 11 in the first field H1 as the operation target based on the location information of the owner terminal 14 (step S140). This allows the field management server 15 to eliminate the need to input the operation target, reducing the workload of the owner P. Also, the water supply apparatus 11 in the first field H1 stops water supply at shorter time intervals (for example, within one minute) than in this specific example (steps S150 to S170).

[0066] This allows water supply apparatus 11 to operate with almost no delay (time lag) in response to owner P's speech, and owner P can operate water supply apparatus 11 without feeling uncomfortable standing next to it. Also, owner P can confirm that the operation of water supply apparatus 11 is complete without having to wait for a long time, so he or she can quickly proceed to the next task. This also improves workability.

[0067] Next, referring to FIG. 5, a device-side operation process for operating water supply device 11 or drainage device 12 based on voice picked up by microphones 11c and 12c of water supply device 11 or drainage device 12 will be described.

[0068] The main unit side operation process shown in Fig. 5 is executed when voice is acquired by microphones 11c and 12c of water supply device 11 or drainage device 12. In the following, the contents of the main unit side operation process will be described using as an example a case where voice is acquired by microphone 11c of water supply device 11, out of water supply device 11 and drainage device 12.

[0069] When the main unit side operation process is executed, the process of step S210 is performed by the water supply control unit 11e of the water supply device 11 that is the same as the microphone 11c that acquired the voice. In step S210, the water supply control unit 11e performs voiceprint authentication of the owner P from the voice acquired by the microphone 11c. The content of the voiceprint authentication is the same as that of step S110 (see FIG. 3). If the water supply control unit 11e authenticates the owner P (step S210: Yes), the process of step S220 is performed. On the other hand, if the water supply control unit 11e cannot authenticate the owner P (step S210: No), the process of step S250 is performed.

[0070] In step S220, the water supply control unit 11e enables the button operation of the operation unit 11b of the water supply device 11 that is the same as the microphone 11c from which the voice was acquired. In this way, the water supply control unit 11e switches the water tap to a state in which it can be manually operated. When the process of step S220 ends, the process of step S230 is performed.

[0071] In step S230, the farm land management server 15 shortens the time interval for communicating with the water supplying device 11 of the microphone 11c from which the voice was acquired. At this time, the farm land management server 15 changes the time interval of the water supplying device 11 so that the time interval becomes shorter (for example, every minute) than the preset time interval (every 10 minutes). When the process of step S230 ends, the process of step S240 is performed.

[0072] In step S240, water supply control unit 11e and farmland management server 15 operate water supply device 11 of microphone 11c from which voice was acquired in response to the operation of operation unit 11b or the owner P's speech. Specifically, when operation unit 11b, whose button operation was enabled in step S220, is operated, water supply control unit 11e operates water supply device 11 in response to the operation of operation unit 11b. Furthermore, when microphone 11c acquires the owner P's speech, farmland management server 15 operates water supply device 11 in response to the owner P's speech. The content of the operation in response to the owner P's speech is the same as in step S160 (see FIG. 3). With this configuration, water supply device 11 can be operated by speech, improving convenience.

[0073] Also, depending on the topography around the field H, the water supply device 11 may be installed in a location where it is difficult to operate the buttons on the operation unit 11b. Even in such a case, the owner P can open and close the water tap by speaking into the water supply device 11 without operating the buttons on the operation unit 11b. This can also improve workability. When the processing of step S240 is completed, the operation processing on the main unit is completed.

[0074] In step S250, which is performed if the owner P cannot be recognized in step S210, the water supply control unit 11e recognizes the sound of rain from the voice acquired by the microphone 11c. Specifically, the water supply control unit 11e analyzes the voice acquired by the microphone 11c and determines whether the voice includes the sound of rain. If the sound of rain is included (step S250: Yes), the process of step S260 is performed. On the other hand, if the sound of rain is not included (step S250: No), the device-side operation process is terminated.

[0075] In step S260, the farm field management server 15 reduces the opening of the water tap of the water supply device 11 corresponding to the microphone 11c from which the voice was acquired, thereby reducing the amount of water supplied to the farm field H. When the process of step S260 ends, the process of step S270 is performed.

[0076] In step S270, the farm field management server 15 lowers the drainage height of the drainage device 12 provided in the same farm field H as the water supply device 11 from the microphone 11c from which the voice was acquired, to make it easier to drain water from the farm field H. When the processing of step S280 ends, the main unit side operation processing ends.

[0077] In this way, when the machine-side operation process recognizes the sound of rain (step S250: Yes), it controls the water supply device 11 and the drainage device 12 (steps S260-S270) to suppress a rise in the water level in the field H. This makes it easier to maintain the water level in the field H at an appropriate level (such as a water level suitable for crop growth) even when it rains.

[0078] Furthermore, in the operation processing on the device side, the processing of step S210 to authenticate the owner P is performed before (given priority to) the processing of step S250 to recognize the sound of rain, so that the water supply device 11 can be operated in response to the owner P's speech even in the rain.

[0079] When the device-side operation process is executed in response to voice acquisition by the microphone 12c of the drainage device 12, the drainage device 12 is operated in response to the owner P's speech or the like (steps S210 to S240). The other processes (steps S250 to S270) are the same as those of the water supply device 11.

[0080] As described above, the field water management system 10 of this embodiment comprises a field water management device (water supply device 11 and drainage device 12) that supplies water to and drains water from the field H, a voice acquisition unit (microphones 11c, 12c, 14c) that acquires voice, a voice recognition unit (water supply control unit 11e, drainage control unit 12e, and terminal control unit 14e) that recognizes the voice acquired by the voice acquisition unit, and a control unit (field management server 15) that controls the water supply and drainage to the field H by operating the field water management device based on the recognition result of the voice recognition unit.

[0081] With this configuration, the owner P can control the water supply and drainage to the field H by voice (for example, the owner P's speech). This can improve convenience.

[0082] The voice acquisition unit includes a first voice acquisition unit (microphone 14a) provided in a terminal (owner terminal 14) capable of communicating with the control unit (farm land management server 15).

[0083] With this configuration, the owner P can control the water supply and drainage to the field H by voice from a location where the terminal is located (for example, the owner P's home, etc.). This can further improve convenience.

[0084] In addition, the field water management system 10 further includes a detection unit (position detection unit 14d) that detects position information of the terminal (owner terminal 14), and a plurality of the field water management devices (water supply devices 11 and drainage devices 12) are provided, and the control unit (field management server 15) determines which field water management device to operate from among the plurality of field water management devices based on the detection results of the detection unit (step S140).

[0085] With this configuration, it is possible to appropriately determine the field water management device (the water supply device 11 and the drainage device 12) to be operated according to the location information of the terminal (the owner terminal 14).

[0086] In addition, the field water management system 10 further includes a detection unit (position detection unit 14d) that detects position information of the terminal (owner terminal 14), and the control unit (field management server 15) determines the operation timing of the field water management device (water supply device 11 and drainage device 12) based on the detection result of the detection unit (step S150).

[0087] With this configuration, the operation timing of the field water management device (the water supply device 11 and the drainage device 12) can be appropriately determined according to the location information of the terminal (the owner terminal 14).

[0088] The voice acquisition section includes a second voice acquisition section (microphones 11c and 12c) provided in the field water management device (the water supply device 11 and the drainage device 12).

[0089] By configuring in this way, it is possible to further improve convenience. In particular, if the owner P is authenticated based on the voice acquired by the second voice acquisition unit (microphones 11c and 12c) as in this embodiment (step S210), it is possible to prevent a third party from operating the field water management device (the water supply device 11 and the drainage device 12) on-site, thereby improving security.

[0090] In addition, when the voice recognition unit (water supply control unit 11e and drainage control unit 12e) recognizes the sound of rain from the voice acquired by the second voice acquisition unit (step S250: Yes), the control unit (field management server 15) controls the field water management device (water supply device 11 and drainage device 12) (steps S260-S270).

[0091] With this configuration, when it rains in the field H (when the voice recognition unit recognizes the sound of rain), the water supply and drainage of the field H can be appropriately controlled.

[0092] The water supply device 11 and the drainage device 12 according to this embodiment are one embodiment of the field water management device according to the present invention. Moreover, the water supply control unit 11e, the drainage control unit 12e, and the terminal control unit 14e according to this embodiment are an embodiment of a voice recognition unit according to the present invention. Moreover, the microphones 11c, 12c, and 14c according to this embodiment are an embodiment of a voice capture unit according to the present invention. Moreover, the owner terminal 14 according to this embodiment is one embodiment of the terminal according to the present invention. Moreover, the microphone 14a of the owner terminal 14 according to this embodiment is an embodiment of a first voice acquisition unit according to the present invention. Moreover, the position detector 14d according to this embodiment is one embodiment of a detector according to the present invention. Moreover, the microphones 11c and 12c of the water supply device 11 and the drainage device 12 according to this embodiment are an embodiment of a second voice acquisition section according to the present invention.

[0093] Although the embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0094] For example, in this embodiment, the owner P is authenticated by voiceprint authentication (step S110), but the owner P may be authenticated by authentication other than voiceprint authentication. For example, the owner P may be authenticated by password authentication, fingerprint authentication, vein authentication, or the like. By authenticating the owner P by such information other than voice, it is possible to prevent a third party from operating the water supply device 11 and the drainage device 12, thereby improving security.

[0095] In the present embodiment, the voices captured by the microphones 11c, 12c, and 14c are recognized within the devices in which the microphones 11c, 12c, and 14c are installed, but the present invention is not limited to this, and the voices may be recognized by an external device. For example, the voice captured by the microphone 11c of the water supply device 11 may be recognized by the farm land management server 15 or the drainage control unit 12e of the drainage device 12.

[0096] Moreover, while the position detection unit 14d is described as being provided in the owner terminal 14, this is not limited thereto and may be provided in other devices. The position detection unit 14d may be provided in, for example, the water supply device 11 or the drainage device 12. In this way, by appropriately communicating between the position detection unit 14d provided in the water supply device 11 or the like and the owner terminal 14, it is also possible to configure the position information of the owner terminal 14 to be detected.

[0097] In the present embodiment, the microphones 11c, 12c, and 14c are provided in the water supply device 11, the drainage device 12, and the owner's terminal 14, but the devices in which the microphones are provided are not particularly limited and can be changed as desired. For example, the microphones may be provided only in the water supply device 11, or may be provided in devices other than the water supply device 11, the drainage device 12, and the owner's terminal 14.

[0098] In this embodiment, the water supply device 11, etc., is remotely operated using the owner terminal 14 (smartphone or tablet terminal), but the device used to remotely operate the water supply device 11, etc. is not particularly limited and can be changed arbitrarily. For example, the water supply device 11, etc. may be remotely operated using a device that the owner P cannot carry (for example, a personal computer, etc.). In this case, the water supply device 11, etc. may be operated by appropriate communication between the device and the farmland management server 15. The water supply device 11, etc. may also be remotely operated using a telephone. In this case, the water supply device 11, etc. may be operated using an automatic response system that automatically responds to a call from the owner P. In this case, the automatic response system may acquire the contents of the owner P's speech over the phone using a microphone, etc., recognize the contents of the speech, and operate the water supply device 11, etc. according to the recognition result. This allows even a person who is not familiar with terminal operation (elderly people, etc.) to easily operate the water supply device 11, etc. by voice.

[0099] In this way, the voice acquisition unit includes a third voice acquisition unit (equipment such as a microphone that acquires the voice of a phone call from owner P in the above-mentioned automatic answering system) that acquires voice from a telephone that is capable of making calls.

[0100] With this configuration, the field water management device (the water supply device 11 and the drainage device 12) can be operated by telephone, further improving convenience.

[0101] Furthermore, when operating water supplying device 11, etc. using a telephone, water supplying device 11, etc. may be operated by receiving telephone dialing operations through an automated answering system, rather than by voice. Furthermore, when operating water supplying device 11, etc. using a telephone, a person (e.g., a call center staff member, etc.) may answer the call, and water supplying device 11, etc. may be operated according to the answering result, rather than using an automated answering system.

[0102] In addition, in the terminal operation process, the operation target is automatically determined based on the position information of the owner terminal 14 (step S140), but the criteria for determining the operation target are not limited to the position information of the owner terminal 14. In the terminal operation process, the operation target can be appropriately determined according to other criteria that can determine the operation target. Furthermore, the operation target may always be selected by the owner P regardless of the position information of the owner terminal 14. Furthermore, the owner P may be able to set in advance whether or not to automatically determine the operation target.

[0103] In the terminal operation process, the time interval for communication between the operation target and the farm land management server 15 is set to either a preset time interval or a specified time interval shorter than the preset time interval (steps S120-S150), but the method for shortening the time interval is not limited to this and can be changed arbitrarily. For example, the time interval may be shortened in a stepwise or stepless manner according to a criterion (such as the distance between the owner terminal 14 and the operation target).

[0104] In addition, in the operation process on the machine side, one of the water supply devices 11 and drainage devices 12 in each field H whose voice is picked up by the microphones 11c and 12c is operated in response to the owner P's speech, but the unit of operation of the water supply devices 11 and drainage devices 12 is not limited to this and can be changed arbitrarily. For example, in the operation process on the machine side, the water supply devices 11 and drainage devices 12 may be operated collectively for each field group G. Also, when multiple water supply devices 11 and multiple drainage devices 12 are provided in one field H, these water supply devices 11 and drainage devices 12 may be operated collectively. Also, the water supply devices 11 and drainage devices 12 of all the fields H owned by the owner P may be operated collectively.

[0105] In this way, the field water management device (water supply device 11 and drainage device 12) is provided in a plurality of fields H, the plurality of fields H are grouped into a plurality of field groups G, and the control unit (field management server 15) controls the field water management device for each field group G based on the results of voice recognition by the second voice acquisition unit (microphones 11c and 12c of the water supply device 11 and drainage device 12).

[0106] With this configuration, the owner P can collectively operate a plurality of field water management devices (field water management devices of fields H belonging to the same field group G) by speaking to one field water management device (the water supply device 11 and the drainage device 12). This can further improve convenience.

[0107] In addition, in the operation process on the machine side, when the sound of rain is recognized by the water supply control unit 11e, the opening degree of the water supply faucet is reduced and the drainage height of the field H is lowered (steps S260-S270). However, the control contents of the water supply device 11, etc. when the sound of rain is recognized are not particularly limited and can be changed arbitrarily. For example, in the operation process on the machine side, when the sound of rain is recognized, either the opening degree of the water supply faucet or the drainage height may be changed. Also, for example, when the sound of rain is recognized, the drainage height may be increased rather than decreased. This allows more precipitation to be stored in the field H, and in the event of heavy rain, water flow from the field H into the river is prevented, thereby preventing the river from flooding or overflowing.
