Taking rice cultivation as an example, a sufficient amount of water is supplied to the paddy field for puddling, and deep water management is continued for a while after rice planting to protect the rice. It is necessary to adjust the water level in the field according to the growth of the rice plants, such as resuming intermittent irrigation after mid-drying to promote root growth and suppress stalk growth, and then allowing the water to fall during the harvesting season.

It is necessary to supply a large amount of irrigation water at the same time as the water supply season of each field overlaps, such as the time of plowing. Although the date and time are planned and managed, even in the same field group, depending on the water pressure of the water supply pipe, there may be cases where a sufficient amount of water cannot be supplied at that time. Otherwise, the amount of water supplied to other fields may be insufficient.

In addition, even in rice cultivation, the timing of water supply may vary depending on the variety of rice, and it is very difficult to plan and manage water supply at the appropriate time and in the appropriate amount according to the unique conditions of each field.

In the field water supply reservation system according to the present invention, in order to flexibly deal with such problems, the above-described irrigation water management server 31 and the field water management server 21 are interconnected via a communication medium such as the Internet, thereby enabling farmers to A field water supply reservation system for reserving irrigation water supply to a field group 10, which is a group of fields 1 is.

Specifically, as shown in FIG. 3 , the field water supply reservation system 200 includes a field water management system 20 and an irrigation water management system 30 .

The field water management system 20 includes a field water management server 21, a terminal device 8 owned by a farmer or the like, a water supply device 2 and a drainage device 4 provided in each field 1, and the like. The field water management server 21 is provided with functional blocks of a water supply reservation accepting means 21A and a field water supply control means 21B. The terminal device 8 includes a portable terminal device such as a smart phone and a stationary terminal device such as a desktop computer.

The total amount of water supply to each field group 10 is adjusted by the field group water supply amount adjusting device. The irrigation water management server 31 is provided with functional blocks of an allowable maximum water supply amount acquisition means 31A, an agricultural field group water supply amount adjustment means 31B, and a water supply schedule management means 31C. In addition, below, the water dividing device 140 may be described as the agricultural field group water supply amount adjusting device 140 .

Each server 21, 31 is provided with a CPU board, a memory board, a communication board, a large-capacity external storage device, etc., and an application program stored in the memory provided on the memory board is executed by the CPU mounted on the CPU board. By doing so, each functional block described above is realized.

The irrigation water management server 31 generates a new water supply available schedule based on each water supply reservation information input from the farm field water management server 21 and outputs it to the farm field water management server 21, and the farm field water management server 21 A timetable based on the water supply available schedule is presented to the terminal device 8, and when the water supply reservation request input from the terminal device 8 can be executed, the water supply reservation is accepted, water supply reservation information is generated, and irrigation water is prepared. It is configured to output to the management server 31 .

The allowable maximum water supply amount acquisition means 31A provided in the irrigation water management server 31 is configured to acquire the allowable maximum water supply amount for each field group 10 within a predetermined period and output it to the water supply schedule management means 31C.

The allowable maximum water supply amount refers to the maximum amount of irrigation water that can be supplied to each field group 10 per day or per hour out of the irrigation water obtained from the water distribution reservoir 121. The water supply amount evenly divided by the device 140 is calculated and stored in the external storage device of the irrigation water management server 31 .

The water supply schedule management means 31C provided in the irrigation water management server 31 determines that the total amount of water supply required for each field group 10 is equal to the maximum allowable water supply amount based on water supply reservation information including field identification information, water supply date and time information, and required water supply amount. A water supply schedule including the water supply volume and the water supply available date and time below the water supply available schedule is stored in the memory on the memory board and output to the field water management server 21 .

When the water supply schedule is input from the water supply schedule management unit 31C, the water supply reservation reception means 21 provided in the field water management server 21 stores the water supply schedule in the memory on the memory board, and receives a reservation confirmation request for the water supply schedule. is presented to the terminal device 8. Then, it is determined whether or not to accept a water supply reservation request specifying the water supply target field 1 and the water supply date and time input from the terminal device 8 .

When the water supply reservation reception means 21 determines that the water supply reservation request can be executed according to the water supply availability schedule, the water supply reservation request is received, and the farm field identification information, the water supply date and time information, and the required water supply amount corresponding to the water supply target farm field. and output to the water supply schedule management means 31C.

The water supply reservation request transmitted from the terminal device 8 operated by the farmer includes information specifying the target field for water supply and information specifying the water supply date and time for that field. It is possible to include a plurality of water supply target fields and a plurality of desired water supply dates or times as water supply dates and times for each field. The desired water supply time is specified by dividing the period from 0:00 to 24:00 into the first period to the fourth period at 6-hour intervals.

The information specifying the water supply date and time is an example, and may be configured to specify the water supply start time or water supply end time. In this case, as will be described later, the required water supply time is calculated from the required water supply amount of the corresponding field 1, and the water supply date/time information is generated. Even when the desired water supply time is not included and only the desired water supply date is provided, the required water supply time is calculated from the similarly calculated required water supply amount, and the water supply date and time information is generated by allocating a time slot without reservation.

Each field group 10 and each field 1 belonging to the field group 10 are stored in advance as a field database in the external storage devices of the field water management system 20 and the irrigation water management system 30, and a water supply reservation information database linked to the database. is stored.

The field database contains records consisting of field information such as field group identification code, field identification code (field identification information), field location, owner code, contact information, field size, and type information of water taps in the field. stored.

The water supply reservation information database stores records composed of field information such as water supply date and time, required water supply amount, water supply completion confirmation information, etc., linked to the field identification code described above.

As described above, the water supply reservation information generated when the water supply reservation reception unit 21A receives a water supply reservation request includes the required water supply amount in addition to the field identification information corresponding to the water supply target field and the water supply date and time information. .

The water supply reservation receiving means 21A calculates the required water supply amount from the field size of the corresponding field and the target water depth of the field 1 . For the water supply to the field 1, a target water depth is set for each management period such as the deep water management period at the time of puddling and rice planting, and the subsequent intermittent irrigation management period. is predetermined.

This target water depth information is provided in association with the water supply date/time information of the water supply reservation request from the terminal device 8 . In this case, the water supply reservation receiving means 21A calculates the required water supply amount from the target water depth, but the water supply reservation request may include information on the required water supply amount. Alternatively, the target water depth information may be held in an agricultural field database. In this case, for example, the water level target for each management period of each field is registered in the field database, and the corresponding management period is derived from the number of elapsed days from the first water supply date of the reserved field to the reserved water supply date. Depth information is derived.

Since the amount of water supply per hour is determined from the model information of the water supply device 2 provided in each field 1, the time required for water supply can also be obtained from the model information. Therefore, the required water supply time information can be included in the required water supply amount.

The water supply reservation receiving means 21A refers to the water supply availability schedule, determines whether or not the required amount of water can be supplied at the farm specified in the water supply reservation request, and the water supply date and time. It accepts and generates water supply reservation information.

When the water supply schedule management means 31C receives the water supply reservation information from the water supply reservation reception means 21A, the water supply schedule management means 31C stores the water supply reservation information in the water supply reservation information database, and obtains the maximum allowable water supply amount acquisition means in order to respond to the next water supply reservation request. A water supply available schedule is sequentially updated and generated so that it can be determined whether or not water supply based on the water supply reservation information is possible within a range that satisfies the allowable maximum water supply amount for each field group 10 acquired by 31A.

The water supply schedule clearly indicates the water supply capacity for each period, for example, along a water supply day within a predetermined period and a timetable that divides the day into first to fourth periods at 6-hour intervals. Since the water supply availability schedule is a water supply availability schedule that reflects the water supply reservation information that has been received so far, the dates and time zones for which water supply is available and the amount of water supply are indicated.

A farmer who enters the field water supply reservation system 200 and makes a water supply reservation can use the water supply availability schedule displayed on the terminal device 8, i. Then, a water supply reservation request is made to the water supply reservation reception means 21A by inputting a water supply reservation so that water can be supplied on a day or date when water supply is possible. A water supply reservation request is made by setting the date or time.

FIG. 4 shows the procedure for generating a water supply available schedule executed by the water supply schedule management means 31C described above, and FIG. 5 shows the procedure for water supply reservation reception executed by the water supply reservation reception means 21A.

When a series of water supply reservation requests are made in this way, the farm field water supply control means 21B remotely operates the water supply device 2 provided in the farm field 1 corresponding to the farm field identification information based on the water supply reservation information stored in the memory. Water is supplied to the agricultural field 1 by opening the water tap under control. Since the accepted water supply reservation request is automatically executed, the farmer is freed from troublesome operations such as going to the field each time and manually operating the water supply device 1 . At this time, it goes without saying that the drainage device 4 is remotely controlled to close the drain plug in advance, or the drainage water level is set to be equal to or higher than the water supply water level.

A water level detected by a water gauge 6 provided in each field 1 is input to the water supply device 2 , and the detected water level is transmitted from the water supply device 2 to the field water management server 21 as water level information of each field 1 . The field water supply control means 21B of the field water management server 21 determines whether or not the water supply based on the corresponding water supply reservation information is completed based on the received water level of the water level gauge 6, and when the target water level is reached, the water supply device 2 is remotely controlled to close the water tap, the water supply to the field 1 is completed.

In addition, the controller of the water supply device 2 may close the water tap by itself based on the water level of the water level gauge 6, and transmit the detected water level to the field water management server 21 as the water level information.

Further, based on the water supply reservation information, the field group water supply amount adjusting means 31B remotely controls the field group water supply amount adjusting device 140 provided corresponding to each farm field group 10 to adjust the water supply amount to each farm field group 10. configured to adjust.

For example, wasteful water distribution can be reduced by supplying water to each field group 10 according to the water supply amount required for each predetermined period based on the water supply reservation information.

Further, the agricultural field group water supply amount adjusting means 31B acquires the water supply information of the agricultural field supplied with water from the agricultural field water supply control means 21B, for example, the water level information of the agricultural field and the opening/closing information of the water tap which is an example of the water supply execution information of the water supply device. to determine the water supply status of the water supply target field, and adjust the amount of water supply to the farm field group having the water supply target field.

Specifically, when information is acquired that the water level has not reached a predetermined level at the scheduled end time or that the water tap is not blocked, the water supply amount of the farm field group 10 having the farm field 1 is increased. Ensure that the water supply can be completed early. Alternatively, it is also possible to acquire water level information from the start of water supply and estimate whether or not water supply will be completed at the scheduled time from the water level rise rate. The water supply amount of the farm field group 10 having the farm field 1 may be adjusted so as to increase the water supply amount.

At this time, the agricultural field group water supply amount adjusting means 31B adjusts the water supply amount of the agricultural field group water supply amount adjusting device 140 within a range not exceeding the allowable maximum water supply amount of the relevant agricultural field group 10 .
Furthermore, if there is a surplus in the water supply amount of the other field groups 10, that is, if the requested water supply amount for which the reservation has been accepted is less than the allowable maximum water supply amount, water supply is possible in a range exceeding the allowable maximum water supply amount. In this case, the allowable maximum water supply amount of each field group 10 is temporarily changed, and when water supply is completed as planned, the water supply amount to each field group 10 and the allowable maximum water supply amount are changed based on returned.

The allowable maximum water supply amount to each field group 10 is, for example, the water supply amount obtained by equally dividing the amount of water pressure-fed from the water distribution reservoir 121 to each field group 10, and the reservation in each field group 10 is the supply amount However, if the water supply amount of each field group 10 has a surplus, the surplus amount may be added to the allowable maximum water supply amount. In this case, the allowable maximum water supply amount is recalculated when the water supply reservation request is received. However, since there is a limit to the water supply amount of the field group water supply amount adjusting device 140, the allowable maximum water supply amount is set within a range that does not exceed this limit.

That is, the agricultural field group water supply amount adjusting means 31B is configured to variably set the allowable maximum water supply amount for each agricultural field group 10 within a predetermined period. Therefore, the timing and amount of water supply to each field 1 can be flexibly adjusted.

In the example described above, based on the fact that it takes approximately 6 hours to fill the average size field 1 with water to a depth of 15 cm, the first period to the second period is 24 hours a day at intervals of 6 hours. An example configured to specify the water supply date and time by dividing into four periods has been described, and an example configured to allow reservation at any time zone has been described, but the water supply schedule is defined by the water supply reservation information. It is preferable to include a preliminary time period for completing water supply.

Even if water supply is started based on the water supply reservation information, sufficient water supply may become difficult due to fluctuations in the water pressure and amount of irrigation water supplied to each field 1 at that time. Even in such a case, if the water supply reservation information includes a preliminary time slot, the water supply specified by the water supply reservation information can be completed by continuing water supply during the preliminary time slot. For example, if the 1st to 3rd periods are 6 hours, the 4th period is 3 hours, and the remaining 3 hours are set as the preliminary time zone, the fields that could not be completely watered in the 1st to 4th periods Water is supplied during this preliminary time zone.

Another aspect of the field water supply reservation system 200 of the present invention will be described below.
In the above-described embodiment, the arrangement for making a water supply reservation request to the farm field water management system 20 via the terminal device 8 has been described. good.

As shown in FIG. 6, the agricultural field water supply reservation system 200 includes an agricultural field water management server 21 having an agricultural field water supply control means 21B, an agricultural field water management system 20 including a water supply device 2, a water supply reservation reception means 31D, and an allowance system. Irrigation water including an irrigation water management server 31 having a maximum water supply amount acquisition means 31A, a water supply schedule management means 31C, and a field group water supply amount adjustment means 31B, and a terminal device 8 for inputting a water supply reservation request to a water supply reservation reception means 31D. A management system 30 is provided.

The irrigation water management server 31 presents the terminal device 8 with a water supply available schedule generated based on each water supply reservation information, and accepts the water supply reservation request when the water supply reservation request input from the terminal device 8 can be executed. is configured to generate water supply reservation information and output it to the farm field water management server 21 . That is, the difference is that the irrigation water management server 31 is provided with a functional block as the water supply reservation receiving means 21A provided in the field water management server 21 .

In the above-described embodiment, the agricultural field water supply reservation system 200 has been described as being composed of the agricultural field water management system 20 and the irrigation water management system 30, but may be composed of a single system. For example, the irrigation water management server 31 shown in FIG.

In the above-described embodiment, the agricultural field water supply reservation system 200 is configured to include the agricultural field group water supply amount adjusting device and the agricultural field group water supply amount adjusting means. And it is good also as a system which does not have a field water supply control means.

In the above-described embodiment, the water supply schedule management means updates and generates the water supply available schedule based on the preset maximum allowable water supply amount. may be configured.

For example, at the water supply reservation stage on the same day, multiple fields belonging to one field group become full and cannot accept water supply reservations due to restrictions on the maximum allowable water supply amount, and at least one other field group has the maximum allowable water supply. When the reservation status is less than the maximum allowable water supply amount, increase the allowable maximum water supply amount for the field group with full reservation and decrease the allowable maximum water supply amount for the field group with the reservation status below the allowable maximum water supply amount. may be adjusted.

In the above-described embodiment, the configuration in which the farm field group water supply amount adjusting device 140 is a water dividing device has been described, but any device that adjusts the water supply to the farm field group 10 can be used. In irrigation water equipment provided with a reservoir for storing water, a pump device may be used, and in irrigation water equipment provided with a water diversion device and a reservoir, the water diversion device and the pump device are combined. may be
