The irrigation water management server 31 is provided with functional blocks of an allowable maximum water supply amount acquisition unit 31A, a field group water supply amount adjustment unit 31B, and a water supply schedule management unit 31C. Hereinafter, the water diversion device 140 may be referred to as a field group water supply amount adjustment device 140.

  Each server 21, 31 is provided with a CPU board, a memory board, a communication board, a large-capacity external storage device, and the like, and an application program stored in a memory provided in the memory board is executed by a CPU mounted on the CPU board. As a result, the functional blocks described above are realized.

  The irrigation water management server 31 generates a newly acceptable water supply schedule based on each water supply reservation information input from the field water management server 21 and outputs it to the field water management server 21. The field water management server 21 A time table based on the water supply 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 and water supply reservation information is generated to generate irrigation water. 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 farm group 10 within a predetermined period and output it to the water supply schedule management means 31C.

  The allowable maximum water supply amount is the maximum water supply amount per day or per hour that can be supplied to each field group 10 among the irrigation water obtained in the distribution reservoir 121. For example, each water supply is divided with respect to the pumped water supply amount of the distribution reservoir 121. The amount of water supply equally 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 is based on the water supply reservation information including the field identification information, the water supply date and time information, and the required water supply amount, and the total required water supply amount for each field group 10 is the allowable maximum water supply amount. It is configured to generate a water supply schedule including a water supply possible amount and a water supply possible date and time, and store the water supply schedule in the memory on the memory board and output it to the field water management server 21.

  When the water supply reservation accepting means 21 provided in the farm water management server 21 receives a water supply schedule from the water supply schedule management means 31C, the water supply reservation reception means 21 stores the water supply reservation in the memory on the memory board, and requests the reservation confirmation. To the terminal device 8. Then, it is determined whether or not a water supply reservation request specifying the water supply target field 1 and the water supply schedule input from the terminal device 8 can be accepted.

  When the water supply reservation accepting means 21 determines that the water supply reservation request can be executed according to the water supply available schedule, the water supply reservation accepting unit 21 accepts the water supply reservation request and receives the field identification information, the water supply date / time information and the required water supply amount corresponding to the water supply target field. Is generated 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 for specifying the water supply target field and information for specifying the water supply schedule for the field. It is possible to include a plurality of desired dates or a desired water supply time as a plurality of water supply target fields and a water supply schedule for each field. The desired water supply time is specified by dividing the period from 0 o'clock to 24:00 from the first period to the fourth period at intervals of 6 hours.

  The information specifying the water supply date / time is an example, and the water supply start time or the water supply end time may be designated. 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 and time information is generated. Even when the desired water supply time is not included and only the desired water supply date is calculated, the required water supply time is calculated from the calculated required water supply amount, and the time zone without reservation is assigned to generate the water supply date and time information.

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

  In the field database, there are records composed of field information such as field group identification code, field identification code (field identification information), field location, owner code, contact information, field size, and field tap type information. Stored.

  In the water supply reservation information database, a record composed of field information such as a water supply date and time, a required water supply amount, and water supply completion confirmation information is stored linked to the above-described field identification code.

  As described above, the water supply reservation information generated when the water supply reservation receiving unit 21A receives the 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 / time information. .

  The water supply reservation accepting 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 a deep water management period at the time of cutting and rice planting, and an intermittent irrigation management period thereafter. Is predetermined.

  This target water depth information is given 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 accepting means 21A calculates the required water supply amount from the target water depth, but information on the required water supply amount may be included in the water supply reservation request. Alternatively, the target water depth information may be held in the 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 days elapsed 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 type information of the water tap provided in the water supply device 2 provided in each field 1, the time required for water supply can be obtained from the type information. Therefore, required water supply time information can be included in the required water supply amount.

  The water supply reservation accepting means 21A refers to the water supply reservation schedule, determines whether or not it is possible to supply only the required amount of water in the field and water supply schedule specified by the water supply reservation request, and if it is determined that the water supply reservation is possible, Receiving and generating water supply reservation information.

  When the water supply schedule management unit 31C receives the water supply reservation information from the water supply reservation receiving unit 21A, the water supply schedule management unit 31C stores the water supply reservation information in the water supply reservation information database and accepts the maximum allowable water supply amount acquisition unit in response to the next water supply reservation request. A water supply schedule that can determine 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 is sequentially updated and generated.

  In the water supply schedule, for example, the water supply capacity within each predetermined period is specified along a water supply day within a predetermined period and a timetable divided from the first period to the fourth period at 6-hour intervals. Since the water supply possible schedule is a water supply possible schedule reflecting the water supply reservation information accepted so far, the date, time zone, and amount of water supply are indicated.

  A farmer who enters the field water reservation system 200 and makes a water reservation makes a request for a field that desires water supply from the water supply schedule displayed on the terminal device 8, that is, a timetable that displays the water supply amount at a predetermined date and time. The water supply reservation request is made to the water supply reservation accepting means 21A by inputting the water supply reservation so as to supply water on the water supply date or time, and if the water supply reservation request is rejected, a new water supply reservation is made. Set a date or date and make a water supply reservation request.

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

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

  The water level detected by the water level 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. 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 meter 6, and when the target water level is reached, the water supply device By remotely controlling 2 and closing the water tap, water supply to the field 1 is completed.

  In addition, you may comprise so that the control part of the water supply apparatus 2 may block a water tap itself based on the water level of the water level meter 6, and may transmit water level information to the farm water management server 21. FIG.

  Further, the field group water supply amount adjustment means 31B remotely controls the field group water supply amount adjustment device 140 provided corresponding to each field group 10 based on the water supply reservation information to control the water supply amount to each 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 amount of water required for each predetermined period from the water supply reservation information.

  Further, the field group water supply amount adjusting means 31B obtains water supply information of the field supplied with water from the field water supply control means 21B, for example, water level information of the field and water supply opening / closing information as an example of water supply execution information of the water supply device. Then, the water supply situation of the water supply target field may be determined, and the water supply amount to the field group having the water supply target field may be adjusted.

  Specifically, by acquiring information that the predetermined water level is not reached at the scheduled end time or that the water faucet is not blocked, the water supply amount of the field group 10 having the field 1 is increased. Ensure that water supply can be completed early. Alternatively, the water level information from the start of water supply may be acquired, and it may be estimated from the rate of increase in water level whether or not the water supply is completed at the scheduled time. You may adjust so that the amount of water supply of the agricultural field group 10 which has the said agricultural field 1 may be increased so that it can supply to water.

At this time, the water supply amount adjustment unit 31B adjusts the water supply amount of the field group water supply adjustment device 140 within a range not exceeding the allowable maximum water supply amount of the field group 10.
Furthermore, when there is a surplus in the water supply amount of the other field group 10, that is, when the requested water supply amount for which the reservation has been received is less than the allowable maximum water supply amount, water supply is allowed 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 the scheduled water supply is completed, the water supply amount to each field group 10 and the allowable maximum water supply amount are based on Returned.

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

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

  In the above-described example, based on the fact that the time required to supply water to the average size of the field 1 until the water depth reaches 15 cm is approximately 6 hours, 24 hours a day from the 1st period to the 6th hour. The example configured to specify the water supply date and time by dividing into four periods has been described, and the example configured to be able to make reservations in any time zone has been described, but the water supply schedule is defined by the water supply reservation information It is preferable that the preliminary time zone for completing the water supply is included.

  Even if water supply is started based on the water supply reservation information, sufficient water supply may be difficult due to fluctuations in the water pressure of the irrigation water supplied to each field 1 and fluctuations in the amount of water. Even in such a case, if a reserve time zone is included in the water supply reservation information, the water supply specified by the water supply reservation information can be completed by continuing the water supply in the reserve time zone. For example, if the first to third periods are 6 hours, the fourth period is 3 hours, and the remaining 3 hours are spare time zones, the fields that could not be completed with water supply from the first period to the fourth period are: Water is supplied during this spare time.

Below, another aspect of the agricultural field water supply reservation system 200 of this invention is demonstrated.
In the above-described embodiment, the configuration in which the water supply reservation request is made to the farm water management system 20 via the terminal device 8 has been described, but the water supply reservation request may be made to the irrigation water management system 30 via the terminal device 8. Good.

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

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

  In the above-described embodiment, the farm water supply reservation system 200 has been described as having the farm water management system 20 and the irrigation water management system 30, but may be configured as a single system. For example, the irrigation water management server 31 shown in FIG. 6 may be provided with a function block of the field water supply control means to control the water supply device 2.

  In the embodiment described above, the farm water supply reservation system 200 has been described with the configuration including the farm field water supply amount adjustment device and the farm field water supply amount adjustment unit, but may be a system that does not include these, and further, the water supply device 2. And it is good also as a system which is not provided with an agricultural field water supply control means.

  In the above-described embodiment, an example in which the water supply schedule management unit updates and generates the water supply possible schedule based on the preset allowable maximum water supply amount has been described. However, the water supply schedule management unit changes and sets the allowable maximum water supply amount. It may be configured.

  For example, at the water supply reservation stage on the same day, the water supply reservation cannot be accepted due to the limitation of the allowable maximum water supply amount in a plurality of fields belonging to one field group, and the allowable maximum water supply in one or more other field groups. When the reservation status is less than the maximum amount, the allowable maximum water supply amount for the field group whose reservation is full is increased and the allowable maximum water supply amount for the field group in the reservation state that is less than the allowable maximum water supply amount is decreased. You may adjust.

  In the above-described embodiment, the configuration in which the field group water supply amount adjustment device 140 is a water diversion device has been described. However, the present invention is not limited to this as long as it is a device that adjusts water supply to the field group 10, and irrigation supplied to the field group 10 The irrigation water facility provided with a reservoir for storing water may be a pump device, and the irrigation water facility provided with a water diversion device and a reservoir is a combination of the water diversion device and the pump device. It may be.

  The embodiment described above is merely an example of the present invention, and is not intended to limit the technical scope of the present invention by the description, and is specific to the field drain plug, the field water storage management system, and the water storage management server. It goes without saying that such a configuration can be changed and designed as appropriate within the scope of the effects of the present invention.
