[Composition of field map]
FIG. 5 shows an example of irrigation water equipment. The irrigation water equipment is a water supply equipment for supplying irrigation water taken from a water source pond 330 such as a river or lake to each field 1 via the distribution reservoir 321, and the distribution reservoir 321 and each field 1 are connected to each other as a main line. The water supply pipe 320 is connected to the water supply pipe 300, which is a branch line.

The water distribution reservoir 321 is a facility for storing pumped water for irrigation to be supplied to each field group FG.Irrigation water is pumped up by a pump of a pumping station 331 provided in the water source reservoir 330, and the water level is maintained at a constant level. A water supply pipe 320 is connected to a water distribution port of the water distribution reservoir 321, and pumped water for irrigation is pumped by water pressure.

The main water supply pipe 320 is branched from the water distribution reservoir 321 toward each field group FG, and a water diversion device 340 is provided that functions as a water diversion facility to adjust the amount of water supplied to each branched water supply pipe 300.

Further, each field 1 is provided with a drain plug device 22 having a drain plug 22B, and a drainage channel 20 is provided so that water from each field 1 via the drain plug device 22 is discharged into the river. .

The field map is a field map showing the specific position of each of the above-mentioned fields 1, and a uniquely identifiable field ID is set for each field 1 on the map. Detailed attributes of the field ID attached to the field map are registered in the field database DB.

FIG. 6 shows the data structure registered in the field database DB. The farm field database DB includes administrator records that identify each manager, field records that identify each field, hydrant records that identify each hydrant, hydrant control device records that identify each hydrant control device, and each drain valve. It is equipped with records such as a drain plug record that identifies each drain plug control device, and a drain plug control device record that identifies each drain plug control device.

The manager record stores manager information for each field, and includes field data indicating attributes such as a manager ID, name, address, telephone number, e-mail address, and ID of one or more managed fields.

The field record includes field data indicating attributes such as a field ID, a field address, a manager ID, a hydrant ID, a drain ID, a hydrant control device ID, and a drain control device ID. That is, the water faucet, drain faucet, faucet control device, drain faucet control device, etc. installed in the farm field identified by the farm field ID are uniquely identified.

The hydrant record includes field data indicating attributes such as hydrant ID, field ID, manager ID, model, manufacturer, and hydrant characteristics. The water faucet characteristics include the number of pulses of an encoder (built in the DC motor 141) that defines the opening degree of the water valve, that is, the fully open position, and the motor current value and encoder that indicates the fully closed position, which is the cutoff torque information of the water valve. This includes information such as the number of pulses of water, water faucet pressure characteristics, field water reduction depth characteristics, actuator overload current information, etc. The number of rotations and the direction of rotation of the motor may be specified instead of the number of pulses of the encoder.

The fully open position is defined in advance by the number of pulses of the encoder, with the initial position being the position where the motor current value is driven to a value indicating the fully closed position, and when fully closed, the pulse is determined from the cumulative number of pulses of the encoder when the motor is driven to the fully open position. The motor is driven to the position where the number is subtracted and becomes zero. The same applies when the number of rotations of the motor is used instead of the number of pulses of the encoder. In response to deterioration of the seal member 123, etc., when the motor current value indicating the fully closed position reaches a predetermined value, it is determined that the predetermined cutoff torque has been reached and the motor is stopped, and from then on, that position is changed to the fully open position. It may be corrected as follows. In this case, these characteristic values are transmitted from the hydrant control device 12B to the field water management server 34, and the hydrant characteristics are updated.

The hydrant control device record includes field data indicating attributes such as hydrant control device ID, field ID, administrator ID, model, manufacturer, and device attributes. Device attributes include attributes such as the model, manufacturer, remaining capacity (in this case, no-load voltage value) of the power storage device included in the hydrant control device, and position information received by the GPS receiver provided in the hydrant control device. included.

The drain plug record includes field data such as drain plug ID, field ID, administrator ID, model, manufacturer, and set water level. The drain valve controller record includes field data indicating attributes such as the drain valve controller ID, field ID, administrator ID, model, manufacturer, and the model, manufacturer, and device attributes of the power storage device provided in the drain valve controller. . Device attributes include the model, manufacturer, remaining capacity (in this case, no-load voltage value) of the power storage device installed in the drain valve control device, and location information received by the GPS receiver installed in the drain valve control device. included.

When the cultivation season arrives, the hydrant control device 12B and drain valve control device 22B, which were stored indoors during the winter, are attached to the hydrant 12A and drain plug 22A provided in each field 1, and power supply from the storage battery is started. Then, the water faucet control device 12B and the drain faucet control device 22B are activated and start communicating with the field water management server 21. The series of processing at this time is called initialization processing.

The communication unit 137 of the hydrant control device 12B transmits the position information captured by the GPS receiver 138 and the hydrant control device ID to the field water management server 34. The field map management unit updates the field map information by associating the hydrant control device 12B and the hydrant 12A to which the hydrant control device 12B is attached based on the position information transmitted from the hydrant control device 12B.

The field map management unit compares the location information (latitude and longitude information captured by a GPS receiver) transmitted from the hydrant control device 12B with the address of the field 1, and determines whether the hydrant control device 12B is installed. The hydrant 12A is identified, and the ID of the hydrant control device 12B is registered in the field of the hydrant 12A, and the ID of the hydrant 12A is registered in the field of the hydrant control device 12B.

As a result, the hydrant 12A installed in each field 1 and the hydrant control device 12B are associated with each other. For example, location information (latitude, longitude information) obtained from the address of field 1 using a Geographic Information System (GIS) and location information (latitude, longitude information) transmitted from the hydrant control device 12B. It can be determined that the hydrant control device 12B is attached to the hydrant 12A in the farm field 1 which is the closest. If the position information (latitude, longitude) of the hydrant 12A is registered in advance as field data of the hydrant record in the database, verification will be easier.

The field water management server 34 reads out attribute information including characteristic information of the hydrant 12A to which the hydrant control device 12B is attached from the field map information based on the position information transmitted from the hydrant control device 12B, and controls the hydrant. to device 12B.

The hydrant control device 12B can now appropriately control the installed hydrant 12A based on this attribute information, and even if the hydrant control device 12B installed in the field is replaced with the previous year, it will continue to control the hydrant 12A installed in the field. Past data will be carried over. For example, the appropriate valve opening when opening can be adjusted based on the pressure characteristics of the hydrant, the target water level in the field, etc. can be adjusted based on the water reduction depth characteristics of the field, and the opening degree of the hydrant 12A can be adjusted based on the opening degree information of the hydrant 12A. The control amount of the actuator is determined, the water stop position is determined based on the shutoff torque information of the faucet 12A, and abnormality diagnosis etc. can be performed based on the overload current information of the actuator.

The attribute information of the hydrant control device 12B includes attribution information, that is, the administrator ID, and the field water management server 34 controls the hydrant based on the position information and the hydrant control device ID information transmitted from the hydrant control device 12B. It is configured to determine whether or not the device 12B is attached to the hydrant 12A of the appropriate field 1, and if it is attached to the hydrant 12A of the inappropriate farm 1, the hydrant control device 12B is The system is configured to notify the administrator by e-mail or the like.

For example, it is now possible to appropriately respond to a case where the hydrant control device 12B is mistakenly attached to a hydrant 12A in a field owned by a different manager, or if the hydrant control device 12B is stolen and resold. Security can be improved in a case where the water tap 12A is installed in three different fields.

FIG. 7 shows the procedure of the initialization process executed when the water tap 12A is powered on, and FIG. 8 shows the procedure of the field water management server 34 at that time.

Thereafter, the field water management server 34 outputs a drainage water level adjustment command to the drainage valve control device 22B of the corresponding field 1 at the water supply date and time specified in the water supply schedule stored in the field database DB, and also outputs a drainage water level adjustment command to the corresponding drainage valve control device 22B. A water supply command is output to the hydrant control device 12B of the field 1 to flood each field 1 with water.

In the above example, the mode in which the hydrant device 12 and the drain plug device 22 are connected to the Internet via the repeater 32 has been described. It may be configured with a terminal that can be connected to a mobile phone line and directly connected to the Internet.

The device and other communication devices that serve as child devices communicate wirelessly with each other, and the communication device that is equipped with the parent device and can connect to the Internet sends information such as water level collected from the child devices all at once to a cloud server. The configuration may be such that the information is sent to

The initialization process for the drain plug control device 22B is also performed in the same manner as described above, so the explanation will be omitted. Note that there are cases where the field water management system 100 is not provided with the drain valve control device 22B, but instead uses the drain valve device 22 that manually sets the drainage water level using the drain plug 22A. In that case, the drain valve control device 22B No initialization processing is performed for the .

In the above explanation, the case where the location information capture unit is a GPS receiver has been explained, but the location information capture unit of the present invention is not limited to a GPS receiver, and the location information capture unit of the present invention is not limited to a GPS receiver, and the location information capture unit is not limited to a GPS receiver. Any positional information acquisition mechanism that electronically captures positional information from the holder may be used.

As the location information acquisition mechanism, it is possible to employ an RF-ID tag reader that electronically reads location information from an RF-ID tag equipped with a memory chip that stores location information including the latitude and longitude of water taps and drain plugs. . The RF-ID tag is equipped with a high-frequency antenna, a signal processing unit, and a memory chip, receives radio waves transmitted from the RF-ID tag reader, operates with the energy, reads out the data stored in the memory chip, and transmits it to the outside. The transmitter is configured to store transmitted or received data in a memory chip. If you install such an RF-ID tag on a water hydrant or drain valve installed in the field, when you attach the hydrant control device or drain valve control device to the hydrant or drain valve and start it up, you can The configuration may be such that an RF-ID tag reader provided in a control device or a drain valve control device reads out the positional information of the water tap or drain valve.

As the position information acquisition mechanism, a code reader that reads the contents of a tag printed with the position information of a water tap or drain valve as code information can be employed. A barcode is preferably used as the code information printed on the tag. In addition to the one-dimensional barcode, it is also possible to use a two-dimensional barcode such as a QR code (registered trademark). A code reader is used to read such code information. A barcode scanner or an imaging device can be used as the code reader.

Note that barcode scanners and imaging devices may be attached to the hydrant control device and drain control device at all times, but they are attached to the hydrant control device and drain control device only when necessary, and the barcode scanner and imaging device are printed on the tag. It may be configured to read the code information and output position information to the communication unit, and may be detachably attached so that it can be removed when unnecessary.

The tag with the code information printed on it is attached to the hydrant or drain valve via a wire, etc., and when the hydrant control device or drain control device is attached to the hydrant or drain valve and activated, the tag is attached to the hydrant or drain valve. It can be configured to read the positional information of the water supply faucet or drain faucet using a barcode scanner or an imaging device provided in the water faucet or drain faucet control device.

Note that it is not necessary to permanently install tags with code information printed on hydrants and drain valves; instead, they can be configured to be prepared when a hydrant control device or drain valve control device is attached to a hydrant or drain valve and activated. It's okay. For example, it is possible to suitably use a smartphone installed with a barcode generation/display application that converts location information acquired by a location information acquisition application into a two-dimensional barcode and displays it on a display screen.

When a hydrant control device or a drain control device is attached to a hydrant or drain valve and activated, the application can be executed near the hydrant or drain valve to display location information near the hydrant or drain valve. The two-dimensional barcode may be displayed on the display screen of the smartphone, and the two-dimensional barcode may be read by an imaging device that is detachably attached to the water faucet control device or the drain faucet control device.

Using the above-mentioned field water management system, it is possible to associate agricultural machines working in each field with work contents and manage their history. For example, RF-ID tags equipped with memory chips that store location information, including the latitude and longitude of the facility, are attached to fixed facilities such as water taps and drain valves, and when working in the field. If agricultural machinery is equipped with an RF-ID tag reader, the RF-ID tag reader installed on the agricultural machinery working in each field can read the location information stored in the RF-ID tags installed on water taps and drain valves. It is possible to specify the field where the agricultural machine is working.

Each agricultural machine is equipped with a communication unit that associates the location information acquired by an RF-ID tag reader with an agricultural machine ID that individually identifies each agricultural machine and sends it to the field water management server. If the configuration is configured to also send the work ID that specifies the work content, the field water management server can transmit the field to be worked on, the work date and time, the work content (for example, puddling, tillage, rice planting, chemical application, etc.), and the agricultural machine ID. It can be associated and managed as a work history. If the work schedule for each field is registered in the field water management server in advance, there is no need to transmit the work details from the agricultural machine. The date and time are managed in advance by the field water management server.

Agricultural machines are equipped with RF-ID tags that store agricultural machine IDs that can be used to identify individual agricultural machines, and the RF-ID tag reader installed in the water tap control device or drain valve control device installed in the field is used to carry out work in the field. The system is configured to acquire the agricultural machine ID attached to the agricultural machine to be used, and is configured to transmit the field ID, agricultural machine ID, etc. to the field water management server from the communication section provided in the hydrant control device and the drain valve control device. It is also possible. In this case as well, the field water management server can manage the field as a work history in association with the field to be worked on, the work date and time, the work contents (for example, puddling, tillage, rice planting, medicine application, etc.), and the agricultural machine ID.

Note that the mechanism for acquiring agricultural machine IDs attached to agricultural machinery is not limited to RF-ID tags; barcodes affixed to the body of agricultural machinery can also be installed in water faucet control devices and drain faucet control devices. It may be configured so that the imaging device reads it.

The embodiments described above are merely examples of the present invention, and the technical scope of the present invention is not intended to be limited by the description. It goes without saying that the specific structure, such as the structure of each record registered in the DB, can be changed and designed as appropriate within the scope of achieving the effects of the present invention.
