However, the communication device 70 of the water management device 1 and the external terminal 201B may directly communicate with each other, and the communication method is not limited.

The field water management system has an irrigation mode, a growth monitoring mode, a water monitoring mode, a theft monitoring mode, an intruder monitoring mode, and a field monitoring mode. The field water management system does not have to have all of the irrigation mode, growth monitoring mode, water monitoring mode, theft monitoring mode, intruder monitoring mode, and field monitoring mode, and all combinations are possible. ..
When the external terminal 201B is connected to the support device 201A and performs a predetermined operation, it can be set to any one of the irrigation mode, the growth monitoring mode, the water monitoring mode, the theft monitoring mode, the intruder monitoring mode, and the field monitoring mode. .. It is also possible to set two or more modes at the same time in the field water management system. It is possible to set both the irrigation mode and the water monitoring mode at the same time, or to set the theft monitoring mode and the intruder monitoring mode at the same time.
<Irrigation mode>
When the irrigation mode is set by operating the external terminal 201B, the support device 201A displays the setting screen M1 on the external terminal 201B as shown in FIG. 8A. On the setting screen M1, the unit selection unit 210 for inputting the irrigation unit (control unit), the irrigation selection unit 211, the water level setting unit 212, the detailed setting button 213, and the time setting unit 214 are displayed.

The unit selection unit 210 is a part for inputting whether to set in a field unit (each of the fields H1) or in a predetermined group of a plurality of fields H1. When the field unit is selected, irrigation can be performed in the field H1 unit, and when a group is set, irrigation can be performed in a plurality of field H1 groups. The irrigation selection unit 211 can select constant flooding, flushing, stopping, and the like. In constant flooding, irrigation (water supply) is performed when the water level falls below the control range from the set water level, and irrigation (water supply) is stopped when the water level exceeds the set water level. Flushing is a setting for irrigation (water supply) regardless of the setting. Stop is a setting to stop irrigation (water supply) regardless of the setting. The water level setting unit 212 is a part for setting an upper limit value (upper limit water level) of the water level.

When the detailed setting button 213 is selected, the support device 201A displays the setting screen M2 on the external terminal 201B as shown in FIG. 8B. On the setting screen M2, the control width input unit 215 and the valve opening degree input unit 216 are displayed. The control width input unit 215 is a portion for inputting the control width F1, and is a numerical value indicating the width from the upper limit water level as shown in FIG. By setting the control width F1, the lower limit value (lower limit water level) of the water level is determined. When the input control width F1 is input to a very small value such as less than 1 cm in the control width input unit 215, a warning is displayed on the setting screen M2 and a very small value is input to the control width input unit 215. Encourage not to. The valve opening degree input unit 216 is a portion for inputting the opening degree C1 of the on-off valve 100c (valve body 102).

The time setting unit 214 is a part for setting whether or not to perform irrigation according to the time, and when "ON" is selected, it is possible to set the irrigation start time and the irrigation end time. When "OFF" is selected, irrigation is performed based on the irrigation setting information regardless of the time.
As described above, the irrigation setting information (field unit, group unit, constant flooding, flushing, stop, upper limit water level, control width F1, irrigation start time, irrigation end time) set by the setting screens M1 and M2 , It is stored in the storage device 203 provided in the support device 201A. The support device 201A connects the communication device 70 of the water management device 1 with irrigation setting information (field unit, group unit, constant inundation, flushing, stop, upper limit water level, control width F1, opening C1, irrigation start time, irrigation. End time) is sent.

Further, the support device 201A transmits to the water management device 1 that the irrigation mode is set when the irrigation mode is set. Upon receiving that the communication device 70 of the water management device 1 is in the irrigation mode, the control device 60 performs an operation corresponding to the irrigation mode. In the irrigation mode, the control device 60 controls to supply water to the field H1.
As shown in FIG. 6, the control device 60 of the water management device 1 includes a water level control unit 60A and a water level width changing unit 60B.

As shown in FIG. 9, the water level control unit 60A controls the actuator 10 so that the water level (detected water level) F2 detected by the water level detection device 50a falls within the control width F1. The water level control unit 60A sets the actuator 10 to the opening degree C1 set by the irrigation setting information when the detected water level F2 drops and approaches the lower limit water level when a constant flooding is set, and the field is fielded. Irrigation is performed to supply water to H1. On the other hand, the water level control unit 60A operates the actuator 10 so that the valve body 102 is fully closed when the detected water level F2 rises and approaches the upper limit water level, and stops irrigation (water supply). The water level control unit 60A does not use the water level detected by the water level detection device 50a until the water surface stabilizes. For example, the actuator 10 controls the water level (detected water level) for a predetermined time (water level stop time) after water is supplied. The water level detection device 50a may not measure the water level immediately after the valve body 102 is opened. The water level stop time may be set according to the season. For example, when the ear of rice is large, the water level detection device 50a is measured after the start of water supply, but the detected value after a lapse of a certain time (the lapse of the water level stop time) may be detected as the actual water level.

Further, when the constant flooding is set and the irrigation start time and the irrigation end time are set (constant flooding with a time zone), the water level control unit 60A has a time zone between the irrigation start time and the irrigation end time. In, when the detected water level F2 drops and approaches the lower limit water level, the actuator 10 is set to the opening degree C1 set by the irrigation setting information to perform irrigation to supply water into the field H1. On the other hand, the water level control unit 60A operates the actuator 10 so that the valve body 102 is fully closed when the detected water level F2 rises and approaches the upper limit water level, and stops irrigation (water supply). That is, in the case of constant flooding with a time zone, the valve body 102 is repeatedly opened and closed during the time zone.

When the opening / closing operation of the valve body 102 exceeds a predetermined number of times within a predetermined time (for example, one day), the water level control unit 60A sends the communication device 70 to the support device 201A "the opening / closing operation is performed a predetermined number of times". Notify that it has become "above". The support device 201A notifies that "the opening / closing operation has reached a predetermined number of times or more" within a predetermined time.
The water level width changing unit 60B changes (corrects) the control width F1 of the irrigation setting information. As shown in FIG. 10, as shown in FIG. 10, the control device 60 corresponds to deep water, shallow water, intermittent, medium-dried, intermittent, low-temperature irrigation, shallow water, intermittent, and falling water in order from seedling transplantation (water). Management time) is remembered. Further, the control device 60 stores the numerical values A1, A2, and A3 of the control width F1 corresponding to the water management time. The control device 60 stores the opening degrees A4, A5, and A6 corresponding to the water management time.

The water level width changing unit 60B is, for example, when the control width (setting control width) F1 indicated by the irrigation setting information matches the numerical value A1 in the case of deep water, shallow water, and intermittent period T1 after transplanting the seedlings. , The setting control width F1 is not changed. On the other hand, in the case of the period T1, the water level width changing unit 60B changes (corrects) the control width F1 in the period T1 to the numerical value A1 when the set control width F1 and the numerical value A1 do not match.

Further, for example, in the case of the period T1, the water level width changing unit 60B does not change the set opening degree C1 when the opening degree (set opening degree) C1 indicated by the irrigation setting information matches the numerical value A4. On the other hand, in the case of the period T1, the water level width changing unit 60B changes (corrects) the opening degree C1 in the period T1 to the numerical value A4 when the set opening degree C1 and the numerical value A4 do not match.
The water level width changing unit 60B does not change the set control width F1 when the set control width F1 matches the numerical value A2 in the case of the period T2 of medium drying, interruption, and low temperature irrigation. On the other hand, in the case of the period T2, the water level width changing unit 60B changes (corrects) the control width F1 in the period T2 to the numerical value A2 when the set control width F1 and the numerical value A2 do not match.

Further, the water level width changing unit 60B does not change the set opening degree C1 when, for example, the set opening degree C1 matches the numerical value A5 in the case of the period T2. On the other hand, in the case of the period T2, the water level width changing unit 60B changes (corrects) the opening degree C1 in the period T2 to the numerical value A5 when the set opening degree C1 and the numerical value A5 do not match.
The water level width changing unit 60B does not change the set control width F1 when the set control width F1 matches the numerical value A3 in the case of the period T3 of shallow water, interruption, and falling water. On the other hand, in the case of the period T3, when the set control width F1 and the numerical value A3 do not match, the water level width changing unit 60B changes (corrects) the control width F1 in the period T2 to the numerical value A3.

Further, the water level width changing unit 60B does not change the set opening degree C1 when the set opening degree C1 matches the numerical value A6 in the case of the period T3, for example. On the other hand, in the case of the period T3, when the set opening degree C1 and the numerical value A6 do not match, the water level width changing unit 60B changes (corrects) the opening degree C1 in the period T2 to the numerical value A6.
That is, the water level width changing unit 60B has a set control width F1> A1, a set control width F1> A2, and a set control width F1> A3 in each of the periods T1, T2, and T3. The lower limit is limited. Further, the water level width changing unit 60B sets the set opening C1> A5, the set opening C1> A6, and the set opening C1> A6 in each of the periods T1, T2, and T3. It is restricted. Further, since the water level width changing unit 60B changes the opening degree C1 according to the control widths A1, A2, and A3, the opening / closing operation time, that is, the opening degree is changed according to the control widths A1, A2, and A3. A4, A5, and A6 are variable.

By the way, as shown in FIG. 2C, a plurality of water management devices 1 (1A, 1B, 1C) for supplying water to one field H1 may be installed. In such a case, the irrigation start time and the irrigation end time for performing the water management device 1 (1A, 1B, 1C) may be different, that is, the opening / closing timing of the valve body 102 may be different. In such a case, in the plurality of water management devices 1 (1A, 1B, 1C), among the plurality of water management devices 1 (1A, 1B, 1C), the detected water level F2 of the predetermined water management device 1 is the lower limit water level. When the support device 201A commands a plurality of water management devices 1 (1A, 1B, 1C) to irrigate at the same time, and the detected water level F2 of the predetermined water management device 1 approaches the upper limit water level. The support device 201A commands the plurality of water management devices 1 (1A, 1B, 1C) to finish irrigation at the same time. That is, when a plurality of water management devices 1 (1A, 1B, 1C) for supplying water to the field H1 are installed, the support device 201A synchronizes the irrigation operation.

By the way, in the above-described embodiment, the relationship between the period T1, T2, T3 and the control widths A1, A2, A3, the opening degree A4, A5, A6 is stored in the control device 60, and the periods T1, T2, T3 The control widths A1, A2, A3, the opening degrees A4, A5, and A6 were changed based on Alternatively, the openings A4, A5, and A6 may be changed.

As shown in FIG. 11, the observation camera 80 images the crop U1 such as rice from the side and images the growth of the crop U1. For example, the water level width changing unit 60B estimates the size (plant height (height)) X1 of the crop U1 from the observation data (captured image) captured by the observation camera 80, and deep water, shallow water, intermittent, medium-dried, intermittent, low temperature. The control widths A1, A2, A3, and the opening degrees A4, A5, and A6 are changed by determining whether the time corresponds to the time of irrigation, shallow water, intermittent water, or falling water. In other words, the water level width changing unit 60B determines the growth stage such as the survival stage, the tillering stage, the ear differentiation stage, the scion stage, the flowering stage, and the ripening stage from the state of the crop U1 in the captured image. , The control widths A1, A2, A3, and the opening degrees A4, A5, A6 are changed.

The water level width changing unit 60B increases the control widths A1, A2, and A3 as the crop U1 grows (the growth stage advances). The water level width changing unit 60B reduces the opening degrees A4, A5, and A6 as the crop U1 grows (the growth stage advances), for example. The control widths A1, A2, A3, openings A4, A5, and A6 described above are examples, and may be freely changed depending on the geology of the field H1, the regional system, the type (brand) of the crop U1, and the like. The numerical values of the widths A1, A2, A3, the opening degrees A4, A5, and A6 may be obtained by past achievements, simulations, and the like.

More specifically, the control device 60 makes it possible to image the water surface W10 near the through hole 105 of the on-off valve 100c and the root U1a of the crop U1 closest to the on-off valve 100c.

In the observation camera 80 provided in the water management device 1, when the imaging range G1 includes the water surface W10 around the water management device 1 and the root U1a of the crop U1, the water management does not have the position change mechanism 159B. It may be the device 1. That is, in the water monitoring mode, the observation camera 80 transmits the imaged observation data in the vicinity where the water is supplied to the support device 201A by the communication device 70.

Specifically, the observation camera 80 images the water surface W10, the ripples W11, and the root U1a of the crop U1 when the actuator 10 is operated. In other words, the water surface W10, the ripples W11, and the root U1a of the crop U1 when the valve body 102 is opened under the control of the control device 60 are imaged.
As shown in FIG. 15A, regardless of whether the observation camera 80 is the visible light camera 80a or the infrared camera 80b, the water management device 1 has the device identification information, the imaging time, the captured images of the water surface W10 and the ripples W11. Water surface image), water level, water temperature, opening of on-off valve) are transmitted to the support device 201A as observation data.

In the above-described embodiment, in the water management device 1, the water surface W10 and the ripple W11 when the valve body 102 is opening (opening is zero or more) are acquired as water surface images. Alternatively, in the water monitoring mode, the state of the water surface W10 when the valve body 102 is closed (stopped at zero opening) may be imaged, and the water surface image including the water surface W10 may be transmitted to the support device 201A. ..

Further, the light (illumination device) 230 of the water management device 1 can irradiate the light source toward the ground of the field H1. As a result, the water surface W10 and the ripple W11 can be imaged more clearly. For example, it is easy to grasp the ups and downs of the water surface W10 and the flow of water by taking an image while shining light on the lighting device 230.
As shown in FIGS. 15A and 15B, the support device 201A has observation data (device identification information, imaging time, captured image (water surface image), water level, water temperature, opening / closing valve opening) transmitted from the water management device 1. Is stored in the water surface database 225.

The support device 201A includes a water management unit 228. The water management unit 228 is composed of an electric / electronic circuit, a program, and the like provided in the support device 201A.
As shown in FIG. 14, the water management unit 228 transmits a water surface image including the water surface W10, ripples W11, and the root U1a of the crop U1 to the external terminal 201B, and causes the external terminal 201B to display the water surface image. Alternatively, the water management unit 228 transmits a water surface image including the water surface W10 to the external terminal 201B and displays it on the external terminal 201B. Here, when displaying the water surface image on the external terminal 201B, it is preferable to display the operation information as to whether or not the actuator 10 (valve body 102) is operating together with the water surface image. As a result, the administrator can easily grasp whether or not the image is a water surface when the actuator 10 (valve body 102) is operating.

Alternatively, the water management unit 228 estimates the water level of the field H1 based on the observation data of either the ripple W11 or the water surface W10. In the situation where the actuator 10 (valve body 102) is operating, the water management unit 228 estimates that the water level is deep when the ripple W11 is small, and estimates that the water level is shallow when the ripple W11 is large.
As shown in FIG. 14, the water management unit 228 has an area S1 of the root U1a of the crop U1 shown in the water surface image, an arrangement of the root U1a, an opening degree of the actuator 10 (valve body 102), and a water surface image. Using the indicated ripple W11 as an input value, the water level of the field H1 is estimated by deep learning (artificial intelligence).

For example, when the predetermined opening degree of the actuator 10 (valve body 102) is constant, the area S1 of the root U1a of the crop U1 shown in the water surface image is small, and water is supplied from the front surface (discharge side) of the water management device 1. When the generated water (water) does not easily hit the root U1a, a correlation is established between the number of ripples W11 and the water level. On the other hand, when the predetermined opening degree of the actuator 10 (valve body 102) is constant, the area S1 of the root U1a of the crop U1 shown in the water surface image is large, and water is supplied from the front surface (discharge side) of the water management device 1. When the generated water (water) easily hits the root U1a, the amount of ripples W11 correlates with the area S of the root U1a and the arrangement of the root U1a. Therefore, it is possible to estimate the water level of the field H1 based on the area S1 of the root U1a, the arrangement of the root U1a, the opening degree of the actuator 10 (valve body 102), and the ripple W11 shown in the water surface image. ..

The water level detected by the water level detection device 50a is converted into data in advance, and the water level is used as an actual value. The area S1 of the root U1a of the crop U1, the arrangement of the root U1a, the opening degree of the actuator 10 (valve body 102), and the ripple W1 The water level may be estimated by deep learning using the above as an input value.
The water management unit 228 determines whether or not the estimated water level of the field H1 (estimated water level) is within the target water level of the field H1, that is, between the upper limit water level and the lower limit water level. When the target water level (upper limit water level to lower limit water level) of the field H1 is not reached, the water management unit 228 notifies the water management device 1 that the estimated water level is not within the target water level. When the estimated water level is not within the target water level, the water management device 1 operates the actuator 10 (valve body 102) to supply water.

As shown in FIG. 6, the water management device 1 may include a sound detection device 229. The sound detection device 229 is a sound collector (microphone) or the like that detects sounds around the housing 11. The sound detection device 229 detects, for example, the sound when the actuator 10 (valve body 102) is opened, and transmits the detected sound data (sound data) to the support device 201A via the communication device 70. The support device 201A stores the sound data in the water surface database 225 together with the device identification information, the imaging time, the captured image (water surface image), the water level, the water temperature, and the opening degree of the on-off valve.

The water management unit 228 estimates the water level of the field H1 by deep learning (artificial intelligence) using the sound data, the opening degree of the actuator 10 (valve body 102), and the ripple W11 shown in the water surface image as input values. do. When water is supplied from the water management device 1 into the field H1, the sound changes when the supplied water hits the root U1a of the crop U1, and the sound changes when the water hits the root U1a of many crops U1. That is, there is a correlation between the area S1 of the root U1a of the crop U1 and the arrangement of the root U1a shown in the water surface image and the sound data at the time of water supply, and the sound data is the root U1a of the crop U1 shown in the water surface image. It can be a parameter representing the arrangement of the area S1 and the root U1a of. Therefore, the water management unit 228 can estimate the water level by performing deep learning (artificial intelligence) as described above.

In the water monitoring mode of the above-described embodiment, the water supply side is described, but the water monitoring mode can also be applied to the drainage side. That is, in the explanation in the water monitoring mode, the water supply is read as drainage. That is, when draining, by acquiring a water surface image including the water surface W10, ripples W11, and the root U1a of the crop U1, the water surface image at the time of drainage and the water level at the time of drainage can be confirmed or estimated. That is, in the water monitoring mode, after acquiring the water surface image using the observation camera 80 provided in the water management device 1 on the drainage side, the valve body (partition) 125 is subjected to the above-mentioned operation during water supply by the actuator 10. If it is replaced with the contents that are operating, the explanation will be on the drainage side, so the explanation will be omitted.

By doing so, the steering direction of the front wheels can be changed. The steering device 330 described above is an example, and is not limited to the configuration described above.

The tractor includes a positioning device (second positioning device) 340. When the position is obtained by RTK-GNSS or the like, the positioning device (second positioning device) 340 is on the mobile station side. The positioning device 340 can detect its own position (positioning information including latitude and longitude) by a satellite positioning system (positioning satellite) such as D-GPS, GPS, GLONASS, Beidou, Galileo, and Michibiki. That is, the positioning device 340 receives the satellite signal (position of the positioning satellite, transmission time, correction information, etc.) transmitted from the positioning satellite, and based on the satellite signal, the position of the tractor (for example, latitude, longitude), that is, , Detects the vehicle body position. The positioning device (second positioning device) 340 is on the mobile station side.

The positioning device 340 includes a receiving device 341 and an inertial measurement unit (IMU) 342. The receiving device 341 is a device having an antenna or the like and receiving a satellite signal transmitted from the positioning satellite, and is attached to the traveling vehicle body 303 separately from the inertial measurement unit 342.

As shown in FIG. 17, the tractor includes a control device 360. The control device 360 controls the tractor in various ways. The control device 360 advances and reverses the traveling vehicle body 303 based on the operation of the forward / backward moving member 361a. The control device 360 starts and stops the prime mover 304 based on the operation of the ignition switch 361b. The control device 360 changes the shift stage (shift level) of the shift device 305 based on the operation of the shift change member 361c.

The control device 360 may perform automatic driving control (automatic driving control). In the automatic driving in the control device 360, the traveling vehicle body 303 is automatically driven along a preset traveling route. In the control device 360, at least the traveling position of the traveling vehicle body 303 (the position detected by the positioning device 340) and the preset traveling route (traveling route) match, that is, the traveling vehicle body 303 and the traveling route are aligned with each other. The switching position and opening degree of the control valve 335 are set so as to match. In other words, in the automatic driving mode, the control device 360 sets the moving direction and the moving amount (steering direction and steering angle of the front wheels) of the steering cylinder 336 so that the traveling position of the tractor and the traveling route match. ..

Specifically, in the automatic traveling mode, the control device 360 compares the traveling position of the traveling vehicle body 303 with the position indicated by the traveling route (scheduled traveling position), and the traveling position and the planned traveling position match. If so, the steering angle and steering direction (steering angle and steering direction of the front wheels) of the steering wheel 331 in the steering device 330 are held unchanged (the opening degree and switching position of the control valve 335 are maintained unchanged). ). When the traveling position and the planned traveling position do not match, the control device 360 has the steering angle of the steering wheel 331 and the steering angle of the steering wheel 331 in the steering device 330 so that the deviation (deviation amount) between the traveling position and the planned traveling position becomes zero. / Or change the steering direction (change the opening and / or switching position of the control valve 335).

In the above-described embodiment, the control device 360 changes the steering angle of the steering device 330 based on the deviation between the traveling position and the planned traveling position in the automatic traveling control, but the direction of the traveling route and the tractor When the direction (vehicle body direction) of the traveling direction (traveling direction) of (traveling vehicle body 303) is different, the control device 360 may set the steering angle so that the vehicle body orientation matches the orientation of the traveling route. Further, the control device 360 sets the final steering angle in the automatic driving control based on the steering angle obtained based on the deviation (positional deviation) and the steering angle obtained based on the directional deviation in the automatic driving control. You may. Further, the steering angle may be set by a method different from the steering angle setting method in the automatic traveling control described above. Further, the control device 360 sets the traveling device 301 (that is, the front wheels and / or) so that the actual vehicle speed of the tractor (traveling vehicle body 303) matches the vehicle speed corresponding to the preset traveling route in the automatic traveling control. The number of rotations of the rear wheels) may be controlled. Further, although the control device 360 performs automatic driving by controlling the steering of the traveling vehicle body 303 and the vehicle speed, the vehicle speed may be automatically driven by auto-steering control (automatic steering control) in which the driver adjusts the vehicle speed. Not limited to control. Further, as a matter of course, it is possible for the driver to perform manual operation in which the tractor is manually operated.

As shown in FIG. 17, the tractor includes a storage device 362 that stores machine identification information and a communication device 363. Since the communication device 363 is the same as the communication device 70, the description thereof will be omitted.
As described above, according to the tractor, the work by the work device 302 can be performed by running the field H1 in the state where the work device 302 is connected.

By the way, as shown in FIG. 18A, in the theft monitoring mode, the monitoring device 231A displays the theft setting screen M3 on the external terminal 201B. The theft setting screen M3 includes an image display unit 240 and a field selection unit 241. The image display unit 240 is a portion that displays an image captured by the observation camera 80. The field selection unit 241 is a portion for selecting a predetermined field (monitored field) from the plurality of fields H1, and the field to be monitored can be selected from the field list indicating the plurality of fields H1. The field selection unit 241 may be a portion of the field map in which the field map to be monitored can be selected by displaying the field map, and the field selection unit 241 is not limited.

When the monitored field H1 is selected by the field selection unit 241, the captured image captured by the observation camera 80 of the water management device 1 installed in the selected monitored field H1 is displayed on the image display unit 240.
Specifically, when the monitored field H1 is selected, the monitoring device 231A is a water management device (monitoring water management device 1) installed in the monitored field H1 based on the field identification information of the selected monitored field H1. ) Is extracted, and the monitoring water management device 1 is requested to transmit the image. The communication device 70 of the monitoring water management device 1 transmits the captured image G10 captured by the observation camera 80 to the support device 201A, and the support device 201A transmits the captured image G10 to the external terminal 201B. Alternatively, the communication device 70 of the monitoring water management device 1 directly transmits the captured image G10 captured by the observation camera 80 to the external terminal 201B. Therefore, the captured image G10 of the monitored field H1 can be displayed on the theft setting screen M3.

When the monitoring start button 243 is selected when the image G10 displayed on the image display unit 240 includes the agricultural machine 300 on the theft setting screen M3, the monitoring device 231A changes the monitoring water management device 1. Monitoring based on the captured image G10 of the observation camera 80 is started. If the agricultural machine 300 is not transferred to the captured image G10 displayed on the image display unit 240 (the captured image G10 does not include the agricultural machine 300), the monitoring device 231A indicates that there is no agricultural machine 300 to be monitored. Is displayed on the theft setting screen M3 or the like.

On the other hand, when the monitoring end button 244 is selected, the monitoring device 231A ends the monitoring. In the theft setting screen M3, a monitoring time zone (monitoring time zone) may be input. In this case, during the monitoring time zone, the monitoring device 231A performs monitoring based on the captured image G10 of the observation camera 80 of the monitoring water management device 1.
Specifically, when the monitoring device 231A starts monitoring, the agricultural machine 300 in the captured image G10 stays at the same position and monitors whether or not it is moving (whether or not it is stopped at a predetermined position). To judge). For example, the monitoring device 231A generates a warning when the agricultural machine 300 in the captured image G10 moves and does not appear in the captured image G10 under the monitoring situation.

For example, the monitoring device 231A displays a warning to the external terminal 201B that the agricultural machine 300 has moved during monitoring. Alternatively, the monitoring device 231A outputs a warning signal to the monitoring water management device 1, and the control device 60 of the monitoring water management device 1 lights or blinks the lighting device 230 when the lighting device 230 is provided. A warning is generated by letting it. That is, the lighting device 230 also operates as a warning device.

The monitoring device 231A can determine whether or not it is the agricultural machine 300 by pattern matching of the captured image G10 or the like. Further, in the monitoring device 231A, image data of various agricultural machines 300 may be input and deep learning (artificial intelligence) may be used to determine whether or not the agricultural machine 300 is used.
Further, in a situation where the agricultural machine 300 in the captured image G10 is being monitored by the theft monitoring mode, the monitoring device 231A determines that when only the working device 302 is not projected from the captured image G10 from the traveling vehicle body 303, the traveling vehicle body It is determined that the working device 302 has been removed from 303. Also in this case, as described above, the monitoring device 231A generates a warning.

Further, in the above-described embodiment, the field selection unit 241 is displayed on the theft setting screen M3, and the field H1 to be monitored is selected by the field selection unit 241. However, in the anti-theft mode, the water management device 1 The monitored field H1 may be set by operating the operation panel 43 installed in the above. That is, when the operation panel 43 of the water management device 1 is operated, the monitoring device 231A is set as the monitoring water management device 1 that operates the operation panel 43, and the field H1 corresponding to the monitoring water management device 1 is set as the monitoring target field H1. Set to. In such a case, the monitored field H1 can be set without selecting a predetermined field H1 from the field selection unit 241 displayed on the theft setting screen M3.

Further, in the above-described embodiment, the monitoring device 231A monitors whether or not the agricultural machine 300 is in the captured image G10, but instead, the monitoring device 231A monitors the agriculture in the captured image G10. It is determined whether or not the machine 300 is a legitimate agricultural machine 300, a drive permission signal is transmitted to the agricultural machine 300 if it is a legitimate agricultural machine 300, and a drive permission signal is sent to the agricultural machine 300 if it is not a legitimate agricultural machine 300. Monitoring may be performed so that the drive permission signal is not transmitted.

Specifically, the support device 201A includes a machine registration unit 236. The machine registration unit 236 is composed of an electric / electronic circuit, a program, and the like provided in the support device 201A.
The machine registration unit 236 performs a process of associating the agricultural machine 300 with either the water management device 1 or the field H1. As shown in FIG. 18B, when the external terminal 201B is connected to the support device 201A and performs a predetermined operation, the machine registration unit 236 displays the machine registration screen M4 on the external terminal 201B.

The machine registration screen M4 includes a field selection unit 241, a device input unit 245, and a machine input unit 246. The field selection unit 241 is the same as the above-described embodiment. The device input unit 245 is a part for inputting device identification information of the water management device 1. This is a part for inputting machine identification information (name, model number, serial number, serial code, etc.) of the agricultural machine 300.
When the field H1 is selected on the machine registration screen M4 and the device identification information and the machine identification information are input, the machine registration unit 236 provides related information (field identification information, device identification information and machine identification information) to the support device 201A. It is stored in the machine database 226 provided in. On the machine registration screen M4, the support device 201A can extract the device identification information from the field identification information and the field identification information from the device identification information. Therefore, on the machine registration screen M4, the field selection unit 241 And any one of the device input units 245 may not be present.

As described above, the machine registration unit 236 can associate any of the water management device 1 and the field H1 with the agricultural machine 300. That is, the manager or the like can register the relationship between any of the water management device 1 and the field H1 owned by the farm machine 300 by the machine registration unit 236.
By the way, in the situation where the registration is performed as described above, in the case of the theft monitoring mode, at least one of the support device 201A, the external terminal 201B and the water management device 1 is in the theft monitoring mode for the agricultural machine 300. Send that. Upon receiving that the communication device 363 of the agricultural machine 300 is in the theft monitoring mode, the communication device 363 transmits the machine identification information stored in the storage device 362 to at least the support device 201A, the external terminal 201B, and the water management device 1. When the external terminal 201B and the water management device 1 receive the machine identification information, the received machine identification information is transmitted to the monitoring device 231A. When the support device 201A receives the machine identification information, the monitoring device 231A extracts either the field identification information or the device identification information corresponding to the machine identification information from the machine database 226, and refers to the water management device 1 of the device identification information. Therefore, the captured image G10 captured by the observation camera 80 is requested. Upon receiving the captured image G10, the monitoring device 231A displays the captured image G10 on the external terminal 201B.

The external terminal 201B notifies the support device 201A (confirmation notification) that the agricultural machine 300 has been confirmed when the administrator or the like performs a predetermined operation in the theft monitoring mode. When the support device 201A receives the confirmation notification within the predetermined time, the monitoring device 231A determines that the agricultural machine 300 of the captured image G10 is a legitimate agricultural machine. On the other hand, if the support device 201A does not receive the confirmation notification within the predetermined time, the agricultural machine 300 of the captured image G10 is not determined to be a legitimate agricultural machine. When the monitoring device 231A determines that the agricultural machine 300 is a legitimate agricultural machine, the monitoring device 231A transmits a drive permission signal to the agricultural machine 300. On the other hand, if the monitoring device 231A does not determine that the agricultural machine 300 is a legitimate agricultural machine, the monitoring device 231A does not transmit a drive permission signal to the agricultural machine 300. More specifically, when the agricultural machine 300 is a legitimate agricultural machine, the monitoring device 231A transmits a permission signal to the water management device 1 having the observation camera 80 showing the legitimate agricultural machine, and the water management device 1 The permission signal is transmitted to the agricultural machine 300 via the communication device 70. The monitoring device 231A may transmit the permission signal to the external terminal 201B, and the external terminal 201B may transmit the permission signal to the agricultural machine 300.

When the ignition switch 361b is operated after the communication device 363 of the agricultural machine 300 receives the permission signal, the prime mover 304 is driven. On the other hand, when the communication device 363 of the agricultural machine 300 does not receive the permission signal, the prime mover 304 is not driven even if the ignition switch 361b is operated. That is, only the agricultural machine 300 determined by the monitoring device 231A to be a legitimate agricultural machine 300 can be driven.
<Intruder monitoring mode>
As shown in FIG. 6, the support device 201A includes a monitoring device 231B. The monitoring device 231B is composed of an electric / electronic circuit, a program, and the like provided in the support device 201A. The monitoring device 231B can monitor the invader 270 that has invaded the field H1. The invader 270 is, for example, an animal such as a bird, a dog, a cat, a tatsuki, a fox, or a wild boar. When the intruder monitoring mode is set by operating the external terminal 201B, the support device 201A transmits to the water management device 1 that the intruder monitoring mode is set. Upon receiving that the communication device 70 of the water management device 1 is in the intruder monitoring mode, the monitoring device 231B and the water management device 1 perform an operation corresponding to the intruder monitoring mode.

The support device 201A includes a time measuring unit 248 that measures the time. The timekeeping unit 248 is a timer or the like, and measures the month, day, and time (hours and minutes).
When a predetermined operation is performed on the external terminal 201B in the intruder monitoring mode, the monitoring device 231B displays the monitoring screen M5 on the external terminal 201B as shown in FIG. The monitoring screen M5 includes an image display unit 240 and a time input unit 250. The image display unit 240 is the same as the above-described embodiment. The time input unit 250 can input a time such as a month, a day, and a time (time zone). In the intruder monitoring mode, when the time measured by the time measuring unit 248 reaches the time input to the time input unit 250, the monitoring device 231B instructs the water management device 1 to monitor the intruder, and the water management device 1 The observation camera 80 transmits the captured image G10 to the support device 201A. In the intruder monitoring mode, when the support device 201A receives the captured image G10 transmitted from the water management device 1, the monitoring device 231B transmits the captured image G10 to an external terminal 201B such as an administrator or a worker. The external terminal 201B displays the captured image G10 (surveillance image) on the monitoring screen M5.

As shown in FIG. 20, in the intruder monitoring mode, the captured image G10 is monitored to determine whether or not the invader is 270 corresponding to an animal such as a bird, a dog, a cat, a fox, a fox, or a wild boar. For example, the monitoring device 231B determines whether or not the invading object 270 is an animal based on the size (height H20, width W20), shape, movement, and the like of the invading object 270. The height H20, width W20, shape, movement, etc. of animals such as birds, dogs, cats, foxes, foxes, and wild boars are input to the monitoring device 231B in advance as input values, and deep learning (artificial intelligence) is used. , The monitoring device 231B may determine whether the invader 270 is an animal such as a bird, a dog, a cat, a fox, a fox, or a wild boar.

When the monitoring device 231B determines that the intruder 270 is an animal, it issues a warning via the warning device. The warning device includes any one of the ultrasonic wave generator 190, the sound generator 191 and the light source 192. The water management device 1 is provided with at least one of an ultrasonic wave generator 190 that generates ultrasonic waves, a sound generator 191 that generates sound, and a light source 192 that irradiates light as warning devices. When the invader 270 is an animal, the monitoring device 231B identifies the type of the animal and transmits a signal indicating a frequency that the animal dislikes to the water management device 1 as a control signal. The ultrasonic wave generator 190 of the water management device 1 warns by generating ultrasonic waves based on the control signal.

Alternatively, the monitoring device 231B identifies the type of animal and transmits a sound disliked by the animal to the water management device 1 as a control signal. The sound generator 191 of the water management device 1 warns by generating a sound based on the control signal.
Alternatively, the monitoring device 231B identifies the type of animal and transmits the light disliked by the animal to the water management device 1 as a control signal. The light source 192 of the water management device 1 warns by emitting light based on the control signal.

When the observation camera 80 is a visible light camera 80a and an infrared camera 80b, the monitoring device 231B may switch to either the visible light camera 80a or the infrared camera 80b based on the time measured by the measuring unit 248. good. For example, when the time measured by the time measuring unit 248 is the time zone (morning, daytime, evening) when the sun is shining, the monitoring device 231B is a control signal captured by the visible light camera 80a on the water management device 1. Is output to monitor the intruder 270 with the observation data (captured image G10) of the visible light camera 80a. When the time measured by the time measuring unit 248 is a time zone (night, midnight) when the sun is not setting, the monitoring device 231B outputs a control signal imaged by the infrared camera 80b to the water management device 1. Therefore, the intruder 270 is monitored by the observation data of the infrared camera 80b. Since the time when the sun is shining differs depending on the season, the sunrise time and sunset time of the monitoring device 231B are obtained from the Meteorological Agency and the provider that provides the weather information, and the sunrise time and sunset time are obtained. The time for switching between the visible light camera 80a and the infrared camera 80b may be determined based on the above.

Further, in the intruder monitoring mode, when the intruder 270 is an animal as a result of monitoring the intruder 270, the time and type of intrusion may be transmitted to a server such as the support device 201A or an external terminal 201B.
When there are times when crops are not growing in the field or when they are not used in the closed rice fields, the camera can be fixed in a different direction from the field and used as a crime prevention device.

The monitoring device 231C monitors the agricultural machine 300. When the field monitoring mode is set by operating the external terminal 201B, the support device 201A transmits to the water management device 1 that the field monitoring mode is set. Upon receiving that the communication device 70 of the water management device 1 is in the field monitoring mode, the monitoring device 231C and the water management device 1 perform an operation corresponding to the field monitoring mode. That is, in the field monitoring mode, the surroundings of the field H1 can be monitored by the monitoring device 231C and the water management device 1.

By the way, as shown in FIG. 21, in the field monitoring mode, the monitoring device 231C displays the monitoring screen M6 on the external terminal 201B. The monitoring screen M6 includes an image display unit 240 and a field selection unit 241. The image display unit 240 is a portion that displays images captured by a plurality of observation cameras 80. The field selection unit 241 is the same as the above-described embodiment.

For example, when the monitoring device 231C issues a command to direct the imaging direction X1 to the field B, the monitoring device 231C captures the entire field B so that the observation cameras 80 of the monitoring water management devices 1a, 1c, 1d, 1e, and 1f can image the entire field B. Set the angle of direction X1.

For example, the monitoring device 231C is set so that when the imaging direction X1 is directed to the field B, the entire field B can be imaged by the observation cameras 80 of the monitoring water management devices 1a, 1c, 1d, 1e, and 1f. The monitoring device 231C has an imaging direction X1 of the observation camera 80 of the monitoring water management device 1a of 315deg, an imaging direction X1 of the observation camera 80 of the monitoring water management device 1c of 45deg, and an imaging direction X1 of the observation camera 80 of the monitoring water management device 1d.

Then, the monitoring device 231C transmits the set angle of the imaging direction X1 to the monitoring water management devices 1a, 1c, 1d, 1e, and 1f.

When the monitoring water management devices 1a, 1c, 1d, 1e, and 1f receive the angle (set angle) of the imaging direction X1 set by the monitoring device 231C, the monitoring water management devices 1a, 1c, 1d, 1e, and 1f, respectively. The control device 60 directs the imaging direction X1 toward the field B by operating the electric motor 162 according to the set angle to rotate the turntable 160.
Then, when the setting of the imaging direction X1 is completed, the observation cameras 80 of the monitoring water management devices 1a, 1b, 1c, 1d, 1e, and 1f transmit the captured image G10 to the support device 201A via the communication device 70. ..

The monitoring device 231C displays the captured image G10 of the monitoring water management devices 1a, 1b, 1c, 1d, 1e, and 1f on the image display unit 240. The monitoring device 231C may include an image generation unit 233. The image generation unit 233 generates an image around the field H1 from the captured image. The image generation unit 233 synthesizes the captured images G10 of the monitoring water management devices 1a, 1b, 1c, 1d, 1e, and 1f as an around view image to create a composite image, and the composite image is sent to the external terminal 201B.

The monitoring device 231C may set the height to be imaged constant (fixed) when the field B is imaged by the observation cameras 80 of the monitoring water management devices 1a, 1b, 1c, 1d, 1e, and 1f.

Further, when the monitoring water management devices 1a, 1b, 1c, 1d, 1e, and 1f have a plurality of cameras, the monitoring device 231C may generate an around view image by synthesizing a plurality of captured images G10. Alternatively, the monitoring device 231C synthesizes the captured images G10 before and after the rotation of the turntable 160 as an around view image, and displays the entire field (fields A, B, C, D, E, F from FIGS. 22A and B). Images can also be generated.

Further, the support device 201A may automatically switch between the intruder monitoring mode and the field monitoring mode according to the time measured by the time measuring unit 248. In other words, the observation camera 80 can switch between a field monitoring mode for monitoring the field H1 and an intruder monitoring mode for monitoring the intruder 270 invading the periphery of the field H1 based on the time measured by the time measuring unit 248. .. In the field monitoring mode, the observation camera 80 may be switched according to the time in the same manner as in the intruder monitoring mode. That is, in the morning, daytime, and evening, the monitoring device 231C monitors the field B with the visible light camera 80a, and in the case of night and midnight, the monitoring device 231C attaches the infrared camera 80b to the water management device 1.
