<Communication control device 20>
Next, the configuration of the communication control device 20 will be described.
As shown in FIG. 5, the communication control device 20 includes a control processing unit 21, a communication processing unit 22, a storage unit 23, and an operation unit (not shown) that receives various operations from the user. Further, the storage unit 23 stores a water supply device ID that identifies the water supply device W installed in the paddy field 300.
The water supply device ID is stored in the storage unit 23 at the time of shipment of the product (at the time of manufacture) or at the time of installing the water supply device W by the operation of the manufacturer (or user).

The control processing unit 21 receives the setting of the communication control device 20 by operating an operation unit (not shown).
Further, the control processing unit 21 sends and receives various information to and from the server 100 via the communication processing unit 22, controls the operation of the gate elevating mechanism 50, and forms a lower horizontal bar portion that constitutes the limb portion 1. The hose H placed on the 1c is opened or closed to control the water supply to the paddy field 300.

Specifically, the control processing unit 21 sets the communication processing unit 22 at a predetermined timing (for example, every few hours or at a predetermined time (6:00, 00:00, 15:00, 18:00)). An "inquiry request" for inquiring which state the open / closed state of the hose H controlled by the water supply device W should be set is transmitted to the server 100 via the server 100. This "inquiry request" includes the "water supply device ID" stored in the storage unit 23. That is, the control processing unit 21 reads out the "water supply device ID" stored in the storage unit 23 at a predetermined timing, and includes the "water supply device ID" for the server 100 via the communication processing unit 22. Send the "inquiry request".
After that, the control processing unit 21 receives the "open / close command (open command, close command)" transmitted from the server 100 in response to the "inquiry request" via the communication processing unit 22.

Then, when the "open / close command" transmitted from the server 100 is the "command to close the hose H", the control processing unit 21 refers to the gate elevating mechanism 50 with respect to the rod-shaped gate of the gate elevating mechanism 50. A closing command signal for lowering 53 is transmitted, the rod-shaped gate 53 is lowered downward, and the hose H placed on the lower horizontal bar portion 1c of the leg portion 1 is moved to the rod-shaped gate 53 and the lower horizontal bar. The hose H is crushed by being sandwiched by the portion 1c, and the sandwiched portion (pinching portion) of the hose H is closed and closed.

The closing command signal is a signal for rotating the rotation shaft 51a of the motor 51 in the first direction, and the control processing unit 21 transmits a closing command signal to the motor 51 to rotate the rotation shaft 51a of the motor 51 in the first direction. Rotate to. Then, when the rotation shaft 51a of the motor 51 rotates in the first direction, the rotation shaft 52b rotates in the first direction together with the rotation shaft 51a of the motor 51. Further, when the rotary shaft 52b rotates in the first direction, the nut 52c at the lower end of the rotary shaft 52b also rotates in the first direction, and the elevating shaft 52d screwed into the nut 52c descends downward. As a result, the rod-shaped gate 53 fixed to the lower end of the elevating shaft 52d descends toward the lower horizontal bar portion 1c, and the hose H placed on the lower horizontal bar portion 1c is moved. The hose H is sandwiched between the rod-shaped gate 53 and the lower horizontal bar portion 1c, and the outer peripheral portion of the hose H is crushed by receiving a load, so that the sandwiched portion of the hose H is substantially flat and closed.

Further, the control processing unit 21 drives the motor 51 for a preset time, and then stops driving the motor 51. Even if the drive of the motor 51 is stopped, the elevating shaft 52d fixing the rod-shaped gate 53 is screwed into the nut 52c, so that the rod-shaped gate 53 is connected to the lower horizontal bar portion 1c. The state of being arranged at the position where the hose H is sandwiched is maintained. That is, even after the drive of the motor 51 is stopped, the hose H is sandwiched by the bar-shaped gate 53 and the lower horizontal bar portion 1c, and the outer peripheral portion of the hose H is maintained in a loaded state, and the hose H is closed. It remains in that state.

Further, when the hose H is in the closed state and the "open / close command" received by the control processing unit 21 is a "command to open the hose H", the control processing unit 21 sends the gate elevating mechanism 50 to the gate elevating mechanism 50. On the other hand, an open command signal for raising the bar-shaped gate 53 of the gate elevating mechanism 50 is transmitted, the bar-shaped gate 53 is raised, and the hose H placed on the lower horizontal bar portion 1c of the leg portion 1 is rod-shaped. The rod-shaped gate 53 is arranged at a position separated from the hose H by separating the gate 53. As a result, the load on the outer peripheral portion of the hose H (the load by the rod-shaped gate 53) becomes unloaded and the hose H is opened (water flowing through the hose H is supplied to the paddy field 300).

The above-mentioned open command signal is a signal for rotating the rotation shaft 51a of the motor 51 in the second direction, and the control processing unit 21 transmits the open command signal to the motor 51 to make the rotation shaft 51a of the motor 51 second. Rotate in the direction. Then, when the rotation shaft 51a of the motor 51 rotates in the second direction, the rotation shaft 52b rotates in the second direction together with the rotation shaft 51a of the motor 51. Further, when the rotary shaft 52b rotates in the second direction, the nut 52c at the lower end of the rotary shaft 52b also rotates in the second direction, and the elevating shaft 52d screwed into the nut 52c rises (inside the pipe of the rotary shaft 52b). I will be drawn in). As a result, the rod-shaped gate 53 fixed to the lower end of the elevating shaft 52d rises from the lower horizontal bar portion 1c and is separated from the hose H placed on the lower horizontal bar portion 1c. A rod-shaped gate 53 is arranged in the hose H, and the hose H is opened.

Further, the control processing unit 21 drives the motor 51 for a preset time, and then stops driving the motor 51. Even if the drive of the motor 51 is stopped, the elevating shaft 52d fixing the rod-shaped gate 53 is screwed into the nut 52c, so that the rod-shaped gate 53 is positioned away from the hose H. It is maintained in place and the hose H is kept open.

In response to the request from the control processing unit 21, the communication processing unit 22 transmits an “inquiry request” including the “water supply device ID” to the server 100 via the antenna AT and the repeater 50. .. Further, the communication processing unit 22 receives the "open / close command (open command, close command)" sent from the server 100 via the antenna AT and the repeater 50, and receives the "open / close command" received by the control processing unit 21. (Open order, close order) ”is sent.

In the present embodiment, the communication processing unit 22 wirelessly transmits an "inquiry request" to the repeater 50 installed at a position about 1 to 2 km away, or "open / close command (open command, open command,). It is possible to receive "close command)".

For example, as the communication control device 20, an information processing device having an operation unit such as a CPU, a main storage device, an auxiliary storage device, an I / O interface, a communication interface, a wireless circuit, an antenna, and an operation button can be used. In this case, the auxiliary storage device stores a program for realizing the functions of the control processing unit 21 and the communication processing unit 22. Further, a predetermined area of the auxiliary storage device is the storage unit 23. Then, the functions of the control processing unit 21 and the communication processing unit 22 are realized by the CPU loading the program stored in the auxiliary storage device into the main storage device and executing the program.

<Power supply unit 30>

Further, if the read "water level" is smaller than the read "water level specified value" and the read "open / close status" is "closed", the water supply device control unit 120 changes the hose H from the closed state to the open state. Determine that it needs to be changed. Then, the water supply device control unit 120 generates an "open / close command for opening the hose H" and gives the water supply device W an "open / close command for opening the hose H" via the network NW and the repeater 50. To send. That is, if the "water level" of the paddy field 300 in which the water supply device W that sent the "inquiry request" is installed is smaller than the "water level specified value" and the open / close status is "closed", the water supply device control unit 120 has It is determined that the hose H needs to be changed from the closed state to the open state, and a "open / close command for opening the hose H" is transmitted to the water supply device W. After that, the water supply device control unit 120 accesses the water supply device database 220 and "opens" the "open / close status" of the record in which the water supply device ID that identifies the water supply device W that has transmitted the "open / close command" is registered. Update to.
On the other hand, if the read "water level" is smaller than the read "water level specified value" and the read "open / close status" is "open", the water supply device control unit 120 needs to change the open / closed state of the hose H. Judge that there is no. That is, if the water supply device W that has sent the "inquiry request" is installed and the "water level" of the paddy field 300 is smaller than the "water level specified value" and the open / close status is "open", the water supply device control unit 120 has an open / close status. It is determined that it is not necessary to change the open / closed state of the hose H.

When the water supply device control unit 120 determines that it is not necessary to change the open / closed state of the hose H, the water supply device control unit 120 does not particularly transmit a command to the water supply device W. When the water supply device W that has transmitted the "inquiry request" does not receive the "open / close command" that responds to the "inquiry request", it is assumed that the open / closed state of the hose H does not need to be changed, and the open / closed state of the hose H is currently changed. Keep it as it is (does not work in particular).
Alternatively, when the water supply device control unit 120 determines that it is not necessary to change the open / closed state of the hose H, the water supply device W is notified via the network NW and the repeater 50 in the sense of "opening / closing the hose H". A "command indicating that the status quo is maintained" may be transmitted. Also in this case, the water supply device W maintains the open / closed state of the hose H as it is (does not operate in particular).
Hereinafter, the above-mentioned control process of the water supply device W performed by the water supply device control unit 120 will be described by exemplifying a typical case.

First, the hose H of the water supply device W installed in the paddy field 300 is in the "open state", the water level specified value of the water supply device W is "4 cm", and the paddy field 300 in which the water supply device W is installed. The case where the water level of the water level is "6 cm" (the case where the water supply device ID of the water supply device W shown in FIG. 12 is "w0001") will be described.

The water supply device W installed in the paddy field 300 is stored in the communication control device 20 of the water supply device W to the water supply device control unit 120 of the server 100 via the repeater 50 and the network NW at a predetermined timing. An "inquiry request" including the water supply device ID (in this case, "w0001") is transmitted.

When the water supply device control unit 120 receives the "inquiry request" sent from the water supply device W via the repeater 50 and the network NW, the water supply device control unit 120 accesses the water supply device database 220 and is included in the "inquiry request". The record in which the water supply device ID "w0001" is registered (the top-level record of the water supply device database 220 in FIG. 12) is specified.
Further, the water supply device control unit 120 has a "water level sensor ID (" s0001 "in this case)" and a "water level specified value (in this case," s0001 ") associated with the" water supply device ID "from the specified record. 4 cm ")" and "open / close status (" open "in this case)" are extracted. Further, the water supply device control unit 120 accesses the water level sensor database 210 and extracts the "water level (" 6 cm "in this case)" associated with the extracted "water level sensor ID".

Then, the water supply device control unit 120 starts from the extracted "water level specified value (" 4 cm "in this case)", "open / close status (" open "in this case)" and "water level (" 6 cm "in this case"). , It is determined whether or not it is necessary to change the open / closed state of the hose H of the water supply device W.

Specifically, in this case, in the water supply device control unit 120, the water supply device W that sent the "inquiry request" is installed, the "water level" of the paddy field 300 is larger than the "water level specified value", and the open / close status is high. Since it is open, it is determined that the hose H of the water supply device W needs to be changed from the open state to the closed state. Then, the water supply device control unit 120 generates an "open / close command for closing the hose H" and gives the water supply device W a "open / close command for closing the hose H" via the network NW and the repeater 50. To send.
Further, when the water supply device control unit 120 transmits the "open / close command for closing the hose H", the water supply device W accesses the water supply device database 220 and transmits the "open / close command for closing the hose H". The "open / close status" of the record in which the water supply device ID that identifies is registered is updated to "closed".

After that, when the water supply device W receives the "open / close command for closing the hose H" transmitted by the water supply device control unit 120, the water supply device W lowers the rod-shaped gate 53 of the gate elevating mechanism 50 shown in FIG. 9A. As shown in FIG. 9B, the hose H placed on the lower horizontal bar portion 1c is sandwiched between the rod-shaped gate 53 and the lower horizontal bar portion 1c, and the hose H is crushed. The hose H is closed and closed. As a result, the water flowing through the hose H is stopped, and the supply of water to the paddy field 300 is stopped.

Next, the hose H of the water supply device W installed in the paddy field 300 is in the "closed state", the water level specified value of the water supply device W is "4 cm", and the paddy field in which the water supply device W is installed. A case where the water level of 300 is “2 cm” (a case where the water supply device ID of the water supply device W in FIG. 12 is “w0002”) will be described.

The water supply device W installed in the paddy field 300 is stored in the communication control device 20 of the water supply device W to the water supply device control unit 120 of the server 100 via the repeater 50 and the network NW at a predetermined timing. An "inquiry request" including the water supply device ID (in this case, "w0002") is transmitted.

When the water supply device control unit 120 receives the "inquiry request" sent from the water supply device W via the repeater 50 and the network NW, the water supply device control unit 120 accesses the water supply device database 220 and is included in the "inquiry request". The record in which the water supply device ID "w0002" is registered (the record in the second row from the top of the water supply device database 220 in FIG. 12) is specified.
Further, the water supply device control unit 120 has a "water level sensor ID (" s0002 "in this case)" and a "water level specified value (in this case," s0002 ") associated with the" water supply device ID "from the specified record. 4 cm ")" and "open / close status (" closed "in this case)" are extracted. Further, the water supply device control unit 120 accesses the water level sensor database 210 and extracts the "water level (" 2 cm "in this case)" associated with the extracted "water level sensor ID".

Then, the water supply device control unit 120 starts from the extracted "water level specified value (" 4 cm "in this case)", "open / close status ("closed "in this case)" and "water level (" 2 cm "in this case"). , It is determined whether or not it is necessary to change the open / closed state of the hose H of the water supply device W.

Specifically, in the water supply device control unit 120, the water supply device W that has sent the "inquiry request" is installed, the "water level" of the paddy field 300 is smaller than the "water level specified value", and the open / close status is closed. , It is determined that the hose H of the water supply device W needs to be changed from the closed state to the open state. Then, the water supply device control unit 120 generates an "open / close command for opening the hose H" and gives the water supply device W an "open / close command for opening the hose H" via the network NW and the repeater 50. To send.
When the water supply device control unit 120 transmits the "open / close command for opening the hose H", the water supply device control unit 120 accesses the water supply device database 220 and identifies the water supply device W that has transmitted the "open / close command". Update the "open / close status" of the record in which is registered to "open".

After that, when the water supply device W receives the "open / close command for opening the hose H" transmitted by the water supply device control unit 120, the water supply device W raises the rod-shaped gate 53 of the gate elevating mechanism 50 shown in FIG. 9B. As shown in FIG. 9A, the bar-shaped gate 53 is arranged at a position separated from the hose H placed on the lower horizontal bar portion 1c to open the hose H. As a result, water flows through the hose H, and the water from the hose H is supplied to the paddy field 300.

As described above, according to the first embodiment of the present invention, it is possible to provide an automatic water supply system capable of automatically adjusting the amount of water in a water storage area such as a paddy field or a reservoir at low cost.

Specifically, in the first embodiment, a hose H is connected to a pipe 330 that supplies water to the paddy field 300, which is a water storage area, and a water supply device W that controls the flow and stoppage of water flowing through the hose H is installed. Compared to a water supply system that controls the water supply to the paddy field 300 by providing an automatic on-off valve in the pipe 330, for example, the installation cost can be suppressed and the user is burdened with an excessive cost. There is no.

In addition, the water supply system that provides an automatic on-off valve on the pipe 330 to control the water supply to the paddy field may not operate normally when floating substances such as vegetation flow into the automatic on-off valve. It is considered unrealistic to use it in an environment such as paddy fields where water is flowing.
On the other hand, in the present embodiment, the hose H is sandwiched and crushed by using the rod-shaped gate 53 to stop the water flowing through the hose H, or the rod-shaped gate 53 is arranged at a position away from the hose H to arrange the hose H. The hose H is opened to allow the water of the hose H to flow. Unlike the automatic on-off valve, this configuration does not easily clog floating objects such as vegetation, so it operates stably even when used in an environment such as a paddy field.

Further, in the first embodiment, the gate elevating mechanism 50 of the water supply device W has a rotation mechanism (motor) 51 and a reciprocating movement mechanism 52 that converts the rotation operation of the rotation mechanism 51 into a linear operation and reciprocates in the vertical direction. Since the device is configured to include a rod-shaped gate 53 attached to the lower end of the reciprocating moving mechanism 52 and it is not necessary to use costly components, the water supply device W can be manufactured at low cost. ..

And have.

In the automatic water supply / drainage system of the second embodiment, the server 101 controls the operation of the water supply device Wa and the drainage device Wb so that the water level of the paddy field 300 becomes the "water level specified value" set by the user, and the water supply device. Wa is made to supply or stop water to the paddy field 300 (stop water supply), and the drainage device Wb is made to drain or stop water from the paddy field 300 (stop drainage). As described above, in the second embodiment, since the running water and the water stoppage are controlled on both the water supply side and the drainage side, the water level of the paddy field 300 becomes the "water level specified value" in a shorter time than in the first embodiment. Can be adjusted to

<< Configuration of water supply device and drainage device >>
Next, the configurations of the water supply device Wa and the drainage device Wb constituting the automatic water supply / drainage system of the second embodiment will be described.

Both the water supply device Wa and the drainage device Wb have the same configuration as the water supply device W (see FIGS. 3 to 7) of the first embodiment described above. That is, the water supply device W of the first embodiment functions as a water supply device Wa when it is used to control the flow of water flowing through the hose H for supplying water to the paddy field 300 and the water stoppage, and drains water from the paddy field 300. It functions as a drainage device Wb when it is used to control the flow of water flowing through the hose H and the water stoppage.

Specifically, the water supply device Wa and the drainage device Wb both have a main body portion 10 having a housing portion 2 supported by the limb portion 1 and the limb portion 1, and communication control housed in the housing portion 2. The device 20 includes a power supply unit 30 housed in the housing unit 2, and a gate elevating mechanism 50 held in the main body unit 10. Further, the communication control device 20 includes a control processing unit 21, a communication processing unit 22, a storage unit 23, and an operation unit (not shown) that receives various operations from the user, as in the case of the first embodiment. Have.
The storage unit 23 of the drainage device Wb stores the drainage device ID that identifies the drainage device Wb. This drainage device ID is stored in the storage unit 23 by the operation of the manufacturer (or the user) at the time of shipment of the product (at the time of manufacture) or when the drainage device Wb is installed.

The above water supply device Wa is installed in the paddy field 300 like the water supply device W of the first embodiment described above, so that the water level of the paddy field 300 becomes the "water level specified value" set by the user.
It operates under the control of the server 101 to supply and stop water to the paddy field 300.

Further, as shown in FIG. 14, the drainage device Wb is installed in the agricultural waterway C, operates in response to an opening / closing command from the server 101, and reaches the "water level specified value" set by the user. The drainage of the water stored in the paddy field 300 is drained, or the drainage of the water stored in the paddy field 300 is stopped (stopped).
The agricultural canal C shown in the second embodiment is formed of, for example, soil, and can be installed by driving the tapered portions at the lower ends of the

vertical legs

1a and 1a of the main body 10 into the canal surface. ing. Further, the drainage device Wb is inserted into the cylinders of the

straight leg portions

1a and 1 after the

vertical leg portions

1a and 1a are inserted into the water channel surface of the agricultural waterway C, similarly to the water supply device W of the first embodiment. , A pile (a pile such as an iron pile) P is inserted, and the pile P is driven into the waterway surface, so that the pile P can be installed in the installation area.

Specifically, as shown in FIG. 14, a pipe (drainage pipe) 331 that connects the paddy field 300 and the agricultural canal C is buried in the ridge 320 of the paddy field 300, and water is stored in the paddy field 300. Water can be drained through the pipe 311. One end of the pipe 331 projects toward the paddy field 300 of the ridge 320 (arranged on the paddy field 300 side), and the other end of the pipe 331 projects toward the agricultural canal C of the ridge 320 (arranged on the agricultural canal C side). , Buried in the ridge 320. Further, the hose H is connected to the other end of the pipe 331 arranged on the agricultural waterway C side.
Then, in the second embodiment, the drainage device Wb is installed at a position near the other end of the pipe 331 in the water channel surface of the agricultural waterway C, and the limb 1 constituting the main body 10 of the drainage device Wb is installed. A hose H connected to a pipe (drainage pipe) 331 communicated with the agricultural waterway C is placed on the lower horizontal bar portion 1c.

Then, the gate elevating mechanism 50 of the drainage device Wb operates under the control of the server 101, lowers the rod-shaped gate 53, presses the outer peripheral portion of the hose H placed at a predetermined position of the limb 1, and applies a load. The hose H is crushed and closed, and the water flowing through the hose H (water drained from the paddy field 300) is stopped.
Further, the gate elevating mechanism 50 of the drainage device Wb operates under the control of the server 101, raises the rod-shaped gate 53, and arranges the rod-shaped gate 53 at a position separated from the hose H placed at a predetermined position of the limb 1. The water stored in the paddy field 300 can be drained by allowing the water of the hose H to flow in an open state with no load applied to the outer peripheral portion of the hose H.

Further, the drainage device Wb performs substantially the same treatment as the water supply device W of the first embodiment described above.
Specifically, in the drainage device Wb, the control processing unit 21 communicates at a predetermined timing (for example, every few hours or at a predetermined time (6:00, 00:00, 15:00, 18:00)). An "inquiry request" for inquiring which state the open / closed state of the hose H controlled by the drainage device Wb should be set is transmitted to the server 101 via the processing unit 22. This "inquiry request" includes a "drainage device ID" stored in the storage unit 23. That is, the control processing unit 21 reads out the "drainage device ID" stored in the storage unit 23 at a predetermined timing, and includes the "drainage device ID" for the server 101 via the communication processing unit 22. Send the "inquiry request".
After that, the control processing unit 21 of the drainage device Wb receives the "open / close command (open command, close command)" transmitted from the server 101 in response to the "inquiry request" via the communication processing unit 22.

When the hose H is in the open state and the "open / close command" received by the control processing unit 21 of the drainage device Wb is the "command to close the hose H", the control processing unit 21 is the gate elevating mechanism. A closing command signal for lowering the rod-shaped gate 53 of the gate elevating mechanism 50 was transmitted to 50, and the rod-shaped gate 53 was lowered downward and placed on the lower horizontal bar portion 1c of the leg portion 1. The "hose H connected to the pipe 331" is sandwiched between the rod-shaped gate 53 and the lower horizontal rod portion 1c, and the hose H is crushed to close the sandwiched portion (pinching portion) of the hose H. .. As a result, the flow path from the paddy field 300 to the agricultural canal C is blocked through the hose H and the pipe 331, and the drainage of the water stored in the paddy field 300 to the agricultural canal C is stopped.

Further, when the hose H is in the closed state and the "open / close command" received by the control processing unit 21 of the drainage device Wb is the "command to open the hose H", the control processing unit 21 is the gate elevating mechanism. A hose H is transmitted to the 50 to raise the bar-shaped gate 53 of the gate elevating mechanism 50, raises the bar-shaped gate 53, and is placed on the lower horizontal bar portion 1c of the leg portion 1. The rod-shaped gate 53 is separated from the hose H, and the rod-shaped gate 53 is arranged at a position separated from the hose H. As a result, the load on the outer peripheral portion of the hose H (the load by the rod-shaped gate 53) becomes unloaded, and the hose H is opened. As a result, the flow path from the paddy field 300 to the agricultural canal C is opened via the hose H and the pipe 331, and the water stored in the paddy field 300 is drained to the agricultural canal C.

<< Server 101 >>
Next, the configuration of the server 101 of the second embodiment will be described.
The server 101 of the second embodiment adds the drainage device database 230 to the server 100 of the first embodiment, and the water supply device control unit 120 that was in the server 100 of the first embodiment is added to the water supply / drainage control device 121. It is a deformed one. The water supply / drainage device control unit 121 adds a function of controlling the operation of the drainage device Wb to the water supply device control unit 120.

Specifically, as shown in FIG. 15, the server 101 of the second embodiment has a water level information acquisition unit 110, a water supply / drainage device control unit 121, and a storage unit 131. The water level sensor database 210, the water supply device database 220, and the drainage device database 230 are stored in the storage unit 131.

The hardware configuration of the server 101 is not particularly limited. For example, the server 101 is composed of a computer (one or a plurality of computers) having a CPU, a main storage device, an auxiliary storage device, an I / O interface, and a communication interface, like the server 100 of the first embodiment described above. To. In this case, the auxiliary storage device stores a program for realizing the functions of the water level information acquisition unit 110 and the water supply / drainage device control unit 121. Further, a predetermined area of the auxiliary storage device is the storage unit 131. Then, the functions of the water level information acquisition unit 110 and the water supply / drainage device control unit 121 are realized by the CPU loading the program stored in the auxiliary storage device into the main storage device and executing the program.

Next, the drainage device database 230 stored in the storage unit 131 of the server 101 will be described. The water level sensor database 210 and the water supply device database 220 are the same as those in the first embodiment described above.

As shown in FIG. 16, the drainage device database 230 is installed in the field 230a for registering the drainage device ID that identifies the drainage device Wb, and in the paddy field 300 in which the drainage device Wb identified by the drainage device ID controls the water level. A field 230b for registering a water level sensor ID that identifies the water level sensor S, and a user's desire for the paddy field 300 that manages the paddy field 300 in which the drainage device Wb identified by the drainage device ID controls the water level. A field 230c for registering the water level (specified water level value) and a field 230d for registering information (opening / closing status) indicating the open / closed state of the hose H installed in the drainage device Wb identified by the drainage device ID. It is composed of the provided records (plurality of records). That is, the drainage device database 230 stores the drainage device ID in association with the water level sensor ID, the water level specified value, and the open / close status.

The drainage device ID is unique information for identifying the drainage device Wb, and is composed of alphanumeric symbols and the like. Further, the open / close status is information indicating the current open / closed state of the hose H installed in the drainage device Wb, and "open" or "closed" is registered.

Further, the information registered in the

fields

230a and 230b of the drainage device database 230 is information that the contractor who installs the drainage device Wb accesses and registers the server 101 when the drainage device Wb is installed.
Further, the information registered in the field 230c of the drainage device database 230 is such that the user who manages the paddy field 300 accesses the website provided by the server 101 from his / her own user terminal UT, and the server 101 is displayed on the website. It is registered as the desired water level (water level specified value (cm)).
Further, the information registered in the field 230d of the drainage device database 230 indicates that when the drainage device Wb is installed, the contractor who installs the drainage device Wb accesses the server 101 to check the open / closed state of the hose H at the time of installation. This is information that is registered and then updated by the water supply / drainage device control unit 121.

Next, the water supply / drainage device control unit 121 of the server 101 will be described.

The water supply / drainage device control unit 121 responds to the request from the user terminal UT of the user who manages the paddy field 300 in which the water supply device Wa, the drainage device Wb, and the water level sensor S are installed, to the paddy field 300. Provide a website that accepts the setting of the desired water level (water level specified value).
The user is notified of the installed "water supply device ID for identifying the water supply device Wa and the drainage device ID for identifying the drainage device Wb". The user operates the user terminal UT and inputs "water supply device ID, drainage device ID and desired water level (water level specified value)" on the website.

Then, when the water supply / drainage device control unit 121 receives the "water supply device ID, drainage device ID, and water level specified value" from the user terminal UT on the provided website, it accesses the water supply device database 220 and accepts it. The record in which the water supply device ID is registered is read, the accepted "water level specified value" is registered in the field 220c of the read record, and then the record is stored in the water supply device database 220.
Further, when the water supply / drainage device control unit 121 receives the "water supply device ID, drainage device ID and water level specified value" from the user terminal UT on the provided website, the water supply / drainage device control unit 121 accesses the drainage device database 230 and accepts it. The record in which the drainage device ID is registered is read, the received "water level specified value" is registered in the field 230c of the read record, and then the record is stored in the drainage device database 230.

Further, when the water supply / drainage device control unit 121 receives the "inquiry request (inquiry request including the water supply device ID that identifies the water supply device Wa)" from the water supply device Wa installed in the paddy field 300, the first described above. The same process as that of the water supply device control unit 120 of the server 100 of the embodiment is performed.
That is, the water supply / drainage device control unit 121 accesses the water level sensor database 210 and the water supply device database 220, and opens / closes the hose H of the water supply device Wa using the water level, the specified water level value, and the open / close status registered in each database. It is determined whether or not the state needs to be changed, and if it is determined that it is necessary, an "open / close order (either open command or close command)" is issued to the water supply device Wa that has made the "inquiry request". Send.

Specifically, when the water supply / drainage device control unit 121 receives the "inquiry request" from the water supply device Wa, it accesses the water supply device database 220 and registers the "water supply device ID" included in the "inquiry request". The "water level sensor ID, water level specified value, open / close status" associated with the "water supply device ID" is read from the record.
Further, the water supply / drainage device control unit 121 accesses the water level sensor database 210 and reads out the "water level" associated with the read-out "water level sensor ID".

If the read "water level" is larger than the read "water level specified value" and the read "open / close status" is "open", the water supply / drainage device control unit 121 changes the hose H from the open state to the closed state. Judge that it is necessary. Then, the water supply / drainage device control unit 121 generates an "open / close command for closing the hose H" and gives the water supply device Wa a "open / close command for closing the hose H" via the network NW and the repeater 50. To send. After that, the water supply / drainage device control unit 121 accesses the water supply device database 220 and "closes" the "open / close status" of the record in which the water supply device ID that identifies the water supply device Wa that has transmitted the "open / close command" is registered. Update to.
On the other hand, if the read "water level" is larger than the read "water level specified value" and the read "open / close status" is "closed", the water supply / drainage device control unit 121 needs to change the hose H to the open / closed state. Judge that there is no.

Further, if the read "water level" is smaller than the read "water level specified value" and the read "open / close status" is "closed", the water supply / drainage device control unit 121 changes the hose H from the closed state to the open state. Determine that it needs to be changed. Then, the water supply / drainage device control unit 121 generates an "open / close command to open the hose H" and gives the water supply device Wa a "open / close command to open the hose H" via the network NW and the repeater 50. To send. After that, the water supply / drainage device control unit 121 accesses the water supply device database 220 and "opens" the "open / close status" of the record in which the water supply device ID that identifies the water supply device Wa that has transmitted the "open / close command" is registered. Update to.
On the other hand, if the read "water level" is smaller than the read "water level specified value" and the read "open / close status" is "open", the water supply / drainage device control unit 121 needs to change the open / closed state of the hose H. Judge that there is no.

Further, when the water supply / drainage device control unit 121 receives the "inquiry request (inquiry request including the drainage device ID that identifies the water supply device Wb)" from the drainage device Wb, the water level sensor database 210 and the drainage device database 230 are displayed. Access and use the water level, specified water level value, and open / close status registered in each database to determine whether or not it is necessary to change the open / closed state of the hose H of the drainage device Wb, and determine that it is necessary. In this case, an "open / close command (either an open command or a close command)" is transmitted to the drainage device Wb that has made the "inquiry request".

Specifically, when the water supply / drainage device control unit 121 receives the "inquiry request" from the drainage device Wb, the drainage device database 230 is accessed and the "drainage device ID" included in the "inquiry request" is registered. The "water level sensor ID, specified water level value, open / close status" associated with the "drainage device ID" is read from the record.
Further, the water supply / drainage device control unit 121 accesses the water level sensor database 210 and reads out the "water level" associated with the read-out "water level sensor ID".

If the read "water level" is larger than the read "water level specified value" and the read "open / close status" is "closed", the water supply / drainage device control unit 121 changes the hose H from the closed state to the open state. Judge that it is necessary. Then, the water supply / drainage device control unit 121 generates an "open / close command for opening the hose H" and gives the drainage device Wb an "open / close command for opening the hose H" via the network NW and the repeater 50. To send. After that, the water supply / drainage device control unit 121 accesses the drainage device database 230 and opens the "open / close status" of the record in which the drainage device ID that identifies the drainage device Wb that has transmitted the "open / close command" is registered. Update to.
On the other hand, if the read "water level" is larger than the read "water level specified value" and the read "open / close status" is "open", the water supply / drainage device control unit 121 needs to change the hose H to the open / closed state. Judge that there is no.

Further, if the read "water level" is smaller than the read "water level specified value" and the read "open / close status" is "open", the water supply / drainage device control unit 121 changes the hose H from the open state to the closed state. Determine that it needs to be changed. Then, the water supply / drainage device control unit 121 generates an "open / close command for closing the hose H" and gives the drainage device Wb a "open / close command for closing the hose H" via the network NW and the repeater 50. To send. After that, the water supply / drainage device control unit 121 accesses the drainage device database 230 and "closes" the "open / close status" of the record in which the drainage device ID that identifies the drainage device Wb that has transmitted the "open / close command" is registered. Update to.
On the other hand, if the read "water level" is smaller than the read "water level specified value" and the read "open / close status" is "closed", the water supply / drainage device control unit 121 needs to change the open / closed state of the hose H. Judge that there is no.

When the water supply / drainage device control unit 121 determines that it is not necessary to change the open / closed state of the hose H, the water supply / drainage device control unit 121 does not particularly transmit a command to the “water supply device Wa and the drainage device Wb”. When the "water supply device Wa and the drainage device Wb" that have transmitted the "inquiry request" do not receive the "open / close command" that responds to the "inquiry request", it is assumed that the open / closed state of the hose H does not need to be changed. Maintain the open / closed state of the hose as it is (does not operate in particular).
Alternatively, when the water supply / drainage device control unit 121 determines that it is not necessary to change the open / closed state of the hose H, the water supply / drainage device control unit 121 confirms with the "water supply device Wa and the drainage device Wb" via the network NW and the repeater 50. , "A command indicating the maintenance of the current status of the open / closed state of the hose H" may be transmitted. Also in this case, the "water supply device Wa and the drainage device Wb" maintain the open / closed state of the hose H as it is (does not operate in particular).

As described above, also in the second embodiment of the present invention, the same action and effect as those in the first embodiment described above can be obtained.
Further, in the second embodiment of the present invention, since the running water and the water stoppage are controlled on both the water supply side and the drainage side, the water level of the paddy field 300 is set to the "water level specified value" in a shorter time than in the first embodiment. Can be adjusted to be.

The present invention is not limited to the above-described embodiments (first embodiment, second embodiment), and various modifications can be made within the scope of the gist thereof.

For example, in the above-described embodiment, the water supply device W, Wa (or the drainage device Wb) sends an "inquiry request" to the server 100 (or server 101) at a predetermined timing, and the server 100 receives the "inquiry request". (Or the server 101) determines how to open / close the hose H, but the present invention is not particularly limited to this. The server 100 (or server 101) itself controls the water supply devices W and Wa (or the drainage device Wb) with reference to the water level sensor database 210 and the water supply device database 220 (or the drainage device database 230) at predetermined timings. It is determined whether or not it is necessary to change the open / closed state of the hose H, and when it is determined that the open / closed state needs to be changed, the water supply devices W and Wa (or the drainage device) are used via the repeater 50. An "open / close command (either an open command or a close command)" may be transmitted to Wb). In this way, since it is not necessary for the water supply devices W and Wa (or the drainage device Wb) to transmit the "inquiry request", the amount of communication can be reduced.
In this case, the server 100 (or server 101) sets the preset opening / closing time (opening / closing time set by the user terminal UT to access the server 100) as a predetermined timing, and sets the "open / close command (open command and close command). Either) ”may be sent. Further, for example, the server 100 (or the server 101) issues an "open / close command (either an open command or a close command)" at a predetermined timing when the "open (or close) request" from the user terminal UT is received. You may send it.
Further, the user terminal UT may be able to send an "inquiry request" to the

servers

100 and 101.

Further, in the above-described embodiment (first embodiment, second embodiment), the hose H placed on the lower horizontal bar portion 1c by lowering the bar-shaped gate 53 of the gate elevating mechanism 50 is connected to the bar-shaped gate. The hose H is crushed by being sandwiched between the 53 and the lower horizontal bar portion 1c to close the hose H, but the hose H is not particularly limited to this. The hose H is placed on the rod-shaped gate 53 of the gate elevating mechanism 50, the rod-shaped gate 53 is raised, and the hose H is crushed by being sandwiched between the rod-shaped gate 53 and the upper horizontal bar portion 1b to crush the hose H. May be closed and the hose H may be opened by lowering the rod-shaped gate 53.

Further, for example, in the above-described embodiment, the water supply devices W, Wa, the drainage device Wb, and the water level sensor S communicate with the

servers

servers

100 and 101 via a network NW such as the Internet, and the water supply devices W, Wa, the drainage device Wb, and the water level sensor S are provided. It may be possible to directly connect to the network NW and communicate with the

servers

100 and 101 without going through the relay device 50.

Further, for example, like the water supply device W, Wa, and the drainage device Wb shown in FIG. 17, the upper side (upper side in the drawing) of the hose H is fixed to the rod-shaped gate 53 by the hose fastener 60, and the hose The lower side (lower side in the drawing) of the hose H may be fixed to the lower horizontal bar portion 1c by the fastener 60. In the illustrated example, the two hose fasteners 60 fix the two points on the left and right sides of the upper side (upper side in the drawing) of the hose H to the rod-shaped gate 53, and the two hose fasteners 60 fix the hose H. Two points on the left and right sides on the lower side (lower side in the drawing) are fixed to the lower horizontal bar portion 1c. With this configuration, the hose H can be opened and closed smoothly.

Further, in the second embodiment described above, the drainage device Wb is installed in the agricultural waterway C, but the drainage device Wb is not particularly limited thereto. For example, as shown in FIG. 18, the drainage device Wb may be installed on the paddy field 300 side.

Then, the hose Hs is attached to the pipe 331 by inserting it into the socket 70 of the hose Hs into the pipe 331 on the paddy field 300 side. Also in this configuration, the same action and effect as the drainage device Wb of the second embodiment described above can be obtained.

Further, in the first and second embodiments described above, the hose is sandwiched between the rod-shaped gate 53 and the lower horizontal rod portion 1c, but this is an example. The lower horizontal bar portion 1c may be replaced with a plate-shaped pedestal portion.

Further, in the first and second embodiments described above, an example in which the cross section of the rod-shaped gate 53 is formed in a C-shape, a cono-shape, or the like has been described, but the present invention is not particularly limited to this. The rod-shaped gate 53 may be formed in a columnar shape (O-shaped cross section). Even in this case, the same action and effect as those of the first and second embodiments described above can be obtained.
