It is connected to any one of them, and the control device 13 is configured to communicate with the remaining control devices 13. Therefore, even if a failure occurs in the control device 13 in one of the agricultural houses 10, the control device 13 can function normally in the other agricultural houses 10, and the influence on the environment for growing plants can be reduced. It is possible to stay in one agricultural house 10. Moreover, even when the arrangement (layout) of the second sensor 21 or the shared device 22 shared by the multiple agricultural houses 10 is changed, the second sensor 21 or the shared device 22 is connected to the control device 13 that is easy to connect. What is necessary is just to connect, and it becomes possible to respond easily to a change in arrangement.

The control device 13 includes an environmental element monitored by the second sensor 21 in the input information, and controls the shared device 22 together with the individual device 12 based on the output information, and the first sensor 11 monitors It is desirable to include a switching unit 134 that uses only the environmental element to be used as input information and switches between a second state in which only the individual device 12 is controlled based on output information.

It is desirable that all the agricultural houses 10 have the same configuration, and the first sensor 11 and the individual device 12 have the same configuration in all the agricultural houses 10.

Hereinafter, the configuration of the present embodiment will be described in more detail. In embodiment described below, the case where the five agricultural houses 10 are installed side by side is assumed. However, the purpose is not to limit the number of agricultural houses 10. The agricultural house 10 is configured by using a metal pipe frame as a structural material and a covering material such as a synthetic resin film or glass that transmits light. In many cases, the agricultural house 10 has a rectangular planar shape (a shape that occupies the ground), four side walls, and a roof that covers the side walls. In many cases, the cross section intersecting in the longitudinal direction is formed in a semicircular shape or a triangular shape. This type of agricultural house 10 is called a vinyl house or a pipe house.

FIG. 2 shows a configuration example of the agricultural house 10. The illustrated agricultural house 10 includes a frame 31 configured by combining metal pipes as a structural material, and a covering material 32 supported by the frame 31. The covering material 32 is a synthetic resin film having translucency (desirably, transparent).

The agricultural house 10 includes a roof portion 100 having a semicircular cross section, a pair of

side wall portions

101 and 102 that support the roof portion 100 and face each other, and a pair of wife wall portions that are orthogonal to the

side wall portions

101 and 102 and face each other. 103 and 104 are integrally provided. The size of the agricultural house 10 in the direction passing through the pair of

wall portions

103 and 104 is sufficiently larger (for example, 10 times or more) than the size in the direction passing through the pair of

side wall portions

101 and 102. Therefore, in the following, the direction passing through the pair of

end wall portions

103 and 104 is referred to as a longitudinal direction, and the direction passing through the pair of

side wall portions

101 and 102 is referred to as a short direction. The agricultural house 10 described above is an example, and is not intended to limit the configuration of the agricultural house 10, and does not prevent the agricultural house 10 from using other materials or being formed into other shapes.

The agricultural house 10 is provided with a watering device 51 for irrigating the field 41 and a mist generating device 52 for generating mist above the plants planted in the field 41 in order to control the plant growing environment.

The watering device 51 includes a watering tube 511 formed of a flexible material. The watering tube 511 is disposed along the longitudinal direction of the agricultural house 10 between the side wall portion 101 and the agricultural field 41 and between the side wall portion 102 and the agricultural field 41. The watering tube 511 is provided with small holes (not shown) at a plurality of locations, and when water is injected, water is ejected upward of the farm field 41 through the small holes. The water ejected from the watering tube 511 falls to the field 41 and irrigates the field 41.

The mist generating device 52 includes a water supply pipe 521 suspended from the frame 31 so as to be positioned above the farm field 41. A nozzle (not shown) for generating mist is attached to an appropriate portion of the water supply pipe 521, and is configured to generate mist from the nozzle by pouring water into the water supply pipe 521. The mist hardly contributes to the supply of moisture to the field 41, but if the mist is generated, the temperature around the field 41 can be lowered.

The watering device 51 and the mist generating device 52 include a first drive unit 121 (see FIG. 3) configured to inject water into the watering tube 511 and the water supply pipe 521. The first drive unit 121 includes a device that injects water from a water source into the watering tube 511 and the water supply pipe 521 like a pump, and a device that adjusts the timing of water injection into the watering tube 511 and the water supply pipe 521 like a valve. Is provided. The water source supplies water selected from well water, city water, river water, rain water, etc., and the water is stored in a tank. The valve is assumed to have a configuration that can only be opened and closed, such as an electromagnetic valve, but may have a configuration in which the flow rate can be adjusted, such as an electric valve.

Further, the agricultural house 10 includes a curtain 61 configured to adjust the incidence of external light to the field 41 and a side window 62 that is opened and closed to ventilate the agricultural house 10. The curtain 61 is desirably provided along the roof portion 100, the side wall portion 101, and the side wall portion 102 of the agricultural house 10. The side windows 62 are respectively provided on the side wall 101 and the side wall 102 of the agricultural house 10.

The curtain 61 is between a first position (closed position) that reduces or blocks external light incident on the interior of the agricultural house 10 and a second position (open position) that attenuates external light incident on the interior. It is configured to be movable. The curtain 61 is driven by the second drive unit 122 (see FIG. 1). In order to move the curtain 61, the second drive unit 122 moves the curtain 61 between the first position and the second position by a power source (not shown) such as a motor and a driving force from the power source. And a drive mechanism configured to move.

The 2nd drive part 122 may be comprised so that the curtain 61 provided in each 3 site | parts of the roof part 100 of the agricultural house 10, the side wall part 101, and the side wall part 102 may be moved independently. desirable. Depending on whether each of the three curtains 61 is moved to the first position or the second position, the degree to which external light is dimmed changes, and the amount of heat flowing into the agricultural house 10 is adjusted.

The side window 62 is movable between an open position for allowing ventilation between the inside and the outside of the agricultural house 10 and a closed position for preventing ventilation between the inside and the outside. The side window 62 adjusts the ventilation resistance of air when ventilating between the inside and the outside of the agricultural house 10 by adjusting the opening degree. The agricultural house 10 may include windows (not shown) in the

end wall portions

103 and 104 in addition to the

side wall portions

101 and 102. As for the 2nd drive part 122, it is desirable to be comprised so that the side window 62 provided in the side wall part 101 and the side wall part 102 may be driven independently. In order to move the side window 62, the second driving unit 122 is configured to move the side window 62 between a power source (not shown) such as a motor and an open position and a closed position. A drive mechanism.

When the opening degree of each side window 62 is changed, the speed at which air flows between the inside and the outside of the agricultural house 10 is adjusted. That is, by changing the opening degree of each side window 62, the speed at which air is exchanged between the inside and outside of the agricultural house 10 is adjusted, and the internal temperature of the agricultural house 10 is adjusted. Therefore, if there is a temperature difference between the inside and the outside of the agricultural house 10, the internal temperature of the agricultural house 10 is adjusted by adjusting the respective opening degrees of the side windows 62. Further, if there is a difference in humidity between the inside and outside of the agricultural house 10, the internal humidity of the agricultural house 10 is also adjusted by adjusting the opening degree of each side window 62.

As described above, the internal temperature and internal humidity of the agricultural house 10 can be adjusted by appropriately adjusting the position of the curtain 61 and the opening of the side window 62. For example, if the curtain 61 is closed and the opening degree of the side window 62 is increased during a sunny day in the summer, an increase in the internal temperature of the agricultural house 10 is suppressed.

Also, a ventilation fan 63 is attached to the upper part of the

wife walls

103 and 104 of the agricultural house 10. The ventilation fan 63 is configured to forcibly exhaust the air inside the agricultural house 10 or to introduce the outside air of the agricultural house 10 into the inside. That is, the ventilation fan 63 can be used for adjusting the temperature and humidity of the agricultural house 10 as long as there is a temperature difference or humidity difference between the inside and the outside of the agricultural house 10, similarly to the side window 62.

The configuration of the agricultural house 10 described above is an example, and it is not essential that the agricultural house 10 includes the watering device 51, the mist generating device 52, the curtain 61, the side window 62, and the ventilation fan 63. That is, some of the facilities described above may not be provided in the agricultural house 10, and another facility may be added to the agricultural house 10. However, in this embodiment, the structure provided with the installation mentioned above as the agricultural house 10 is assumed.

In the present embodiment, it is assumed that all the agricultural houses 10 in a plurality of buildings have the same configuration, and the first sensor 11 and the individual device 12 have the same configuration in all the agricultural houses 10. However, even when the configuration of the agricultural house 10 is different in some ridges, or when the agricultural house 10 having a different configuration of the first sensor 11 or the individual device 12 is included, the individual control devices 13 are different. This can be dealt with by operating.

The agricultural house 10 only needs to be arranged close enough that external environmental elements that influence the growth of plants grown using the agricultural house 10 can be regarded as equal among the external environments. In short, a plurality of agricultural houses 10 need only be arranged within a range of several hundred meters. Regarding the agricultural house 10 installed in this way, environmental factors may vary due to the influence of buildings, trees, etc. existing in the vicinity, but overall times such as sunrise and sunset times, weather conditions, etc. It can be said that environmental elements are almost equal.

As shown in FIG. 1, each agricultural house 10 includes a first sensor 11 that monitors an environmental element and an individual device 12 that adjusts the environmental element. The environmental element may include the temperature and humidity around the plant to be grown and the amount of water in the soil, the temperature in the soil, the concentration of carbon dioxide around the plant to be grown, and the like. In some cases, the illuminance inside the agricultural house 10 and the wavelength component of light may be included in the environmental elements.

Therefore, the first sensor 11 includes a temperature sensor and a humidity sensor that are installed so as to monitor the temperature and humidity around the plant, and a soil moisture sensor that monitors the amount of moisture in the soil. As the first sensor 11, a temperature sensor that monitors the temperature in the soil, a CO ₂ sensor that monitors the concentration of carbon dioxide around the plant, and the like are used as necessary. It is desirable that the temperature sensor and the humidity sensor are housed in the same case and integrated as a temperature / humidity sensor. When the illuminance or the wavelength component of light is considered as an environmental element, the first sensor 11 may include an illuminance sensor, a color sensor, and the like. As shown in FIG. 3, the agricultural house 10 of the present embodiment shows an example including a temperature / humidity sensor 111 and a soil moisture sensor 112 as the first sensor 11.

The individual device 12 is a device having a function of adjusting environmental elements for each agricultural house 10. In the present embodiment, as the individual device 12, a watering device 51 for watering a plant, a mist generating device 52 for generating mist above the plant, a curtain 61 for dimming or shielding sunlight, a side window 62 used for air replacement, A ventilation fan 63 that ventilates the agricultural house 10 is assumed. The individual device 12 may include a blower fan that blows air to remove the humidity around the plant.

Also, depending on the type of plant grown in the agricultural house 10 and the area where the agricultural house 10 is installed, it may be desirable to adjust the concentration of carbon dioxide, and heating may be necessary. Therefore, the individual device 12 may include a device that generates carbon dioxide and a heating device for heating (in many cases, due to gas combustion).

The water sprinkler 51 is configured to sprinkle the entire field mainly in order to adjust the water content of the soil (field) where the plant is grown. For example, the watering device 51 supplies water to the watering tubes 511 arranged along the

side walls

101 and 102 of the agricultural house 10 and ejects water (or nutrient solution) from small holes formed at appropriate positions of the watering tubes 511. Is configured to give moisture to the field. Moreover, the mist generating apparatus 52 is equipped with the structure which spreads mist above a plant by supplying water to the water supply pipe arrange | positioned above the agricultural field, and ejecting water from the nozzle provided in the appropriate place of the water supply pipe. . Mist is used as a function of regulating the temperature around the plant rather than a function of giving water to the plant. However, when using mist for humidification, mist is sprayed over a long time.

The ventilation device is selected from a side window 62 that is provided on the side wall or the roof and whose opening is adjusted, and a ventilation fan 63 that performs forced exhaust. The side window 62 and the ventilation fan 63 are used for adjusting the temperature and humidity. In particular, if the plant is a soft vegetable such as spinach or komatsuna, if the surrounding humidity remains high, there will be inconveniences such as the possibility of causing diseases, so it is necessary to adjust the humidity with a ventilator. It is.

The curtain 61 includes a ceiling curtain disposed along the roof portion 100, a side curtain disposed along the

side wall portions

101 and 102, and the like. The agricultural house is adjusted by adjusting the amount of solar radiation incident on the agricultural house 10. Regulates internal temperature rise at 10 and regulates plant photosynthesis.

Since the individual device 12 described above adjusts environmental elements in which plants grow in each individual agricultural house 10, it is desirable to control each individual agricultural house 10. Therefore, the control apparatus 13 is provided in each agricultural house 10. The control device 13 generates output information using the environmental element monitored by the first sensor 11 as input information, and controls the individual device 12 based on the generated output information.

As described above, the individual device 12 includes the watering device 51, the mist generating device 52, the curtain 61, the side window 62, the ventilation fan 63, and the like. In the present embodiment, the individual devices 12 are divided into a first group that includes supply of water or nutrient solution, such as the watering device 51 and the mist generating device 52, and a second group that includes other individual devices 12. In the illustrated example, the control device 13 is configured to individually control the first drive unit 121 that controls the operation of the first group and the second drive unit 122 that controls the operation of the second group. Yes. It is not essential to classify the individual devices 12 into two groups, and the control device 13 can perform appropriate control according to the type of the first sensor 11 or the type of the individual device 12.

The control device 13 is built in a control panel (not shown) installed in each agricultural house 10 or is provided as a dedicated device in each agricultural house 10. When the control panel includes a sequencer (PLC: Programmable Logic Controller), the function of the control device 13 can be realized by a sequencer program. Even when a dedicated device is configured, it is desirable that a device including a processor that operates according to a program is configured as a main hardware element. This type of device is selected from a micro controller that includes a processor and a memory integrally, as well as a device that requires a separate memory (ie, MPU (Micro-Processing Unit)).

As shown in FIG. 3, the control device 13 includes a processing unit 130 that performs the above-described processing, a first interface unit 131 that receives input information from the first sensor 11, and a first unit that provides output information to the individual device 12. 2 interface units 132. Furthermore, the control device 13 also includes a communication interface unit 133 for communicating with the control device 13 installed in another agricultural house 10. The communication interface unit 133 may be configured to communicate through a wired communication path. However, if the communication interface unit 133 is configured to communicate through a wireless communication path, no wiring for communication is required between the agricultural houses 10. The advantage that it becomes easy is obtained. In the figure, the interface unit is described as I / F.

Since the control device 13 includes the communication interface unit 133, if information is exchanged with the control device 13 installed in another agricultural house 10, the operation of the individual device 12 between the different agricultural houses 10. Can be linked to each other. However, there are cases where it is not necessary to link the individual devices 12 in the plurality of agricultural houses 10 as in the case where different plants are grown for each agricultural house 10. Therefore, the control device 13 includes a switching unit 134 that switches between a first state that cooperates with the other control device 13 and a second state that does not cooperate with the other control device 13. The operation of the switching unit 134 will be described later.

By the way, the watering device 51 or the mist generating device 52 needs to be supplied with water or nutrient solution. Below, it is called water including nutrient solution. In each agricultural house 10, it is necessary to manage the timing and amount at which water is ejected from the watering device 51 and the timing and amount at which mist is generated from the mist generating device 52. It can be shared in the house 10.

Therefore, the water supplied to the watering device 51 and the mist generating device 52 is collectively managed by the shared device 22. The shared device 22 has a function of distributing water that is collectively managed according to a request from each agricultural house 10. Although the shared device 22 of this embodiment manages only water, when supplying carbon dioxide to the agricultural house 10, the shared device 22 manages the carbon dioxide in a lump, and each agricultural house. Distribute carbon dioxide to 10. The shared device 22 is mainly used for introducing a supply for adjusting the environment for growing plants, such as water or carbon dioxide, from the outside of the agricultural house 10. However, it is not essential that the shared device 22 is configured to introduce supplies to the agricultural house 10.

FIG. 4 shows a configuration example of the shared device 22 that collectively manages water. In the illustrated example, water is introduced into the common tank 223 through the water supply valve 222 from the water source 221 that supplies water selected from well water, city water, river water, rain water, etc., and the water stored in the common tank 223 is used for each agriculture. It is configured to distribute to the house 10. When well water is used as the water of the water source 221, the water source 221 includes a well pump for pumping up the well water. The amount of water stored in the shared tank 223 is determined to have an appropriate range, and is controlled such that the appropriate range is maintained by controlling the water supply valve 222 or the well pump and water supply valve 222 included in the water source 221.

In order to distribute water to the agricultural house 10, the shared device 22 pumps out water from the shared tank 223, and a water distribution valve 225 provided between the shared pump 224 and the agricultural house 10. And further comprising. The water that has passed through the water distribution valve 225 is distributed to each agricultural house 10 through a pipe 226 having a branch path. As described above, in each agricultural house 10, the first drive unit 121 controls the timing and amount of watering and mist generation.

Further, as described above, since the agricultural house 10 is installed in a place where the environmental elements are approximately equal to the entire external environment, it can be said that the environmental elements outside the agricultural house 10 are common. Therefore, as shown in FIG. 1, the environmental element outside the agricultural house 10 is monitored by the second sensor 21 shared by the plurality of agricultural houses 10 (the control device 13). The environmental element monitored by the second sensor 21 is acquired as input information by the control device 13 installed in any of the agricultural houses 10. Further, when the control device 13 communicates with another control device 13, the other control device 13 also shares the same input information.

The environmental elements monitored by the second sensor 21 include, for example, the temperature of the outside air, the humidity of the outside air, and the illuminance outside the agricultural house 10. Moreover, it is also possible to provide the 2nd sensor 21 which monitors the density | concentration of the carbon dioxide in the external air of the agricultural house 10, the solar radiation amount outside the agricultural house 10, etc. as an environmental element. In the configuration example shown in FIG. 1, as the second sensor 21, a temperature / humidity sensor 211 that monitors the temperature and humidity of the outside air and an illuminance sensor 212 that monitors the illuminance outside the agricultural house 10 are illustrated.

The environmental element monitored by the second sensor 21 is given to the control device 13 as input information. Information to be grasped in the shared device 22, for example, the amount of water stored in the shared tank 223 is not an environmental element, but is given to the control device 13 as input information. The control device 13 to which these input information is given through the communication interface unit 133 is any one of the agricultural houses 10, and the control device 13 is connected to the other control devices 13 as described above. This input information is notified.

Although the specific control content by the control device 13 will not be described in detail, the control device 13 takes the input information received from the second sensor 21 and the shared device 22 into account with the input information from the first sensor 11. The control content of the individual device 12 is determined. Moreover, it requests | requires that the water storage amount of the shared tank 223 in the shared apparatus 22 may be controlled as needed.

For example, it is assumed that the illuminance measured by the illuminance sensor 212 which is the second sensor 21 is high and the temperature measured by the temperature and humidity sensor 111 which is the first sensor 11 disposed inside the agricultural house 10 is high. To do. In this case, the control device 13 is instructed to the second drive unit 122 to close the ceiling curtain as the individual device 12 in order to prevent the temperature around the plant from becoming higher than the allowable temperature that is a growth condition. That's fine.

The control content of the individual device 12 is determined using a display 141 and an operation device 142 as the user interface device 14 connected to the control device 13. The display 141 is preferably a flat panel display such as a liquid crystal display, and the operation unit 142 is preferably a touch pad overlaid on the screen of the flat panel display. This type of user interface device 14 is known as a touch panel. Note that the user interface device 14 in which mechanical switches such as push button switches are arranged around the screen of the display 141 may be used.

The control device 13 includes a storage unit 135, and the control content is stored in the storage unit 135. The control content includes basic conditions that are fixedly set in advance and application conditions that allow user adjustment. The basic condition includes a target value related to the environmental element monitored by the first sensor 11 and a reference value related to the control content of the individual device 12. It is desirable that the basic condition includes a target value related to the environmental element monitored by the second sensor 21. The target value is a basic condition to be maintained by operating the individual device 12. Therefore, the processing unit 130 operates the individual device 12 so as to maintain the environmental element monitored by the first sensor 11 or the second sensor 21 at the target value. The application conditions preferably include an adjustment value that increases or decreases the control content of the individual device 12 with respect to the reference value.

As described above, the environmental elements monitored by the first sensor 11 are the temperature and humidity around the plant, and the amount of water in the soil. If necessary, the temperature in the soil and the concentration of carbon dioxide around the plant. Etc. are included. The environmental element may include illuminance or light wavelength components. The target value for the environmental elements is determined as an upper limit value or a lower limit value for these environmental elements. For example, when the environmental elements monitored by the first sensor 11 are temperature, humidity, and illuminance, the temperature is ** [° C.] or higher, the humidity is ** [%] or lower, and the illuminance is ** [klx] or higher. The target value is determined in the form of “**” means a set value.

Moreover, as above-mentioned, the individual apparatus 12 has the function to adjust an environmental element, and the watering apparatus 51, the mist generator 52, the curtain 61, the side window 62, the ventilation fan 63, etc. are used as needed. , A blower that creates an air current around the plant, a device that generates carbon dioxide, a heating device for heating, and the like. The reference value regarding the control content of the individual device 12 is set according to the type of the individual device 12. For example, since the individual devices 12 that supply water such as the watering device 51 and the mist generating device 52 are controlled so as to manage the operation and non-operation time, the operation time and the non-operation time (interval time) are set. Is done. In addition, the individual device 12 that forms a plant environment without using water has a time zone set for each operation state of the individual device 12.

For example, for the mist generating device 52, the reference value is set in a format such as a time for spraying mist as an operation time ** [seconds] and a time for not spraying mist as an interval time ** [minutes]. In addition, the curtain 61 is set with a reference value in a format such as a time period in which the curtain 61 is closed to block light from ** hour to ** hour.

Here, it is desirable that the target value and the reference value included in the basic conditions are set according to the growth stage of the plant to be grown. That is, when the plant growth stage is divided into a plurality of periods, the storage unit 135 preferably stores basic conditions for each growth stage.

The growth stage is divided into, for example, four stages when the plant is spinach. That is, the first period (stage 1) is a period from sowing to germination, and the second period (stage 2) is a period from germination to four true leaves. The third period (stage 3) is a period from four main leaves to a plant height of 20 cm, and the fourth period (stage 4) is a period until the plant height grows from 20 cm to 25 cm. The end point of the fourth period is the harvest point.

When the basic condition described above is set in the storage unit 135, the processing unit 130 determines whether or not the environmental element monitored by the first sensor 11 satisfies the basic condition. When the environmental element monitored by the first sensor 11 does not satisfy the basic condition, the processing unit 130 operates the individual device 12 for adjusting the corresponding environmental element. The individual device 12 operates according to the reference value stored in the storage unit 135.

Now, with respect to the stage 1 of the plant, the target value of the temperature monitored by the first sensor 11 is set to ** [° C.] or more, and the operation time ** for the mist generator 52 which is the individual device 12 Assume that [seconds] and the interval time are set to ** [minutes]. When the temperature monitored by the first sensor 11 is equal to or higher than ** [° C.], the processing unit 130 provided in the control device 13 operates the mist generating device 52 to reduce the ambient temperature of the plant. And

Here, the mist generating device 52 performs an operation of stopping the generation of mist for ** [minutes] after releasing the mist for ** [seconds]. When the mist is generated, the heat around the plant is taken away by the heat of vaporization, and the temperature monitored by the first sensor 11 is lowered. The operation of mist generation and pause is repeated until the temperature monitored by the first sensor 11 becomes less than ** [° C.]. In other words, the operation time defines the amount of mist, and the interval time defines the frequency with which mist is generated.

The basic conditions are set so that the individual apparatus 12 can be automatically controlled so that the environment of the plant to be grown is maintained in a good state according to the growth stage. That is, even if the user does not adjust the operation content of the individual device 12, an environment suitable for plant growth is automatically maintained. Can be nurtured. On the other hand, since the basic conditions are fixedly set, even if an expert of plant growth or the like tries to adjust the operation of the individual device 12 in order to adjust the quality of the plant, the basic conditions alone are flexible. Can not.

In this embodiment, application conditions are set in the storage unit 135 in order to adjust the control content of the individual device 12 with respect to the reference value. The application condition is an adjustment value set to increase or decrease the control content with respect to the reference value, and an adjustment value added to the reference value and an adjustment value subtracted from the reference value are set. .

For example, in the case of the mist generating device 52, which is the individual device 12, as described above, the reference value of the control content is set for the operation time and the interval time, so the adjustment value is also set for the operation time and the interval time. Is done. Rather than showing the numerical value as it is, the adjustment value is intuitively easier to understand by using a qualitative word indicating whether the value is added to or subtracted from the reference value. Therefore, the word “standard” is associated with the reference value, the word “large” is associated with the adjustment value to be added, and the word “small” or “moderate” is associated with the adjustment value to be subtracted. For example, if the reference value is Vs, the adjustment value to be added to the reference value Vs is Va, and the adjustment value to be subtracted from the reference value Vs is Vb, the basic conditions are Vs, “ Vs + Va for “Large” and Vs−Vb for “Less”.

In the storage unit 135, an adjustment value to be added and an adjustment value to be subtracted for each plant growth stage are set. In addition, as in the case where the individual device 12 is the mist generating device 52, adjustment values may be set for two types of time, that is, operation time and interval time.

The basic conditions and application conditions described above are set in the storage unit 135 using the user interface device 14. During the period during which the individual device 12 is automatically controlled, the information on the basic screen D10 shown in FIG. In the illustrated basic screen D10, a field F1 indicating the growth stage, a field F2 indicating the value of the environmental element monitored by the first sensor 11, and an environmental element monitored by the second sensor 21 are displayed. A field F3 indicating a value is displayed. In the lower part of the screen, a button B1 labeled “Preference adjustment” and a button B2 labeled “Setting” are arranged.

Further, the basic screen D10 shown in FIG. 5 includes a button B3 labeled “growth stage” for selecting a growth stage, and “temporary operation” for temporarily operating the individual device 12 for a predetermined time. The indicated button B4 is arranged. Further, a button B5 labeled "irrigation" for performing additional irrigation, and a button B6 labeled "information" for confirming the operation history and the operating state of the individual apparatus 12 are also shown in the basic screen shown in FIG. It is arranged at D10. The button B4 will be described later. Further, the buttons B5 and B6 are not the gist of the present embodiment, and thus description thereof is omitted.

When the basic condition and application condition are set in the storage unit 135, the button B2 is pressed. Although the button is not a mechanical switch, a button of a mechanical push button switch is simulated by the display 141 and the operation unit 142. Therefore, as with the mechanical push button switch, the operation of the button is referred to as “pressing the button”.

When button B2 is pressed, a screen (not shown) for authenticating the administrator is displayed before displaying the screen for setting the basic conditions. Administrator authentication is performed by entering a password. The manager who sets the basic conditions and the manager who sets the application conditions may be different or the same. Further, it may be divided into an administrator who can set basic conditions and an administrator who can set both basic conditions and application conditions. If the administrator's authority is different, the password is set for each administrator.

Suppose here that the screen for setting basic conditions and the screen for setting application conditions can be displayed once the password is entered once on the screen for authenticating the administrator. That is, it is assumed that the passwords of the administrator who sets the basic conditions and the administrator who sets the application conditions are not distinguished.

∙ If basic conditions are not set, application conditions cannot be set, so the screen for setting basic conditions and the screen for setting application conditions are layered. When the administrator password is entered on the screen for authentication, a screen for selecting the type of the individual device 12 is displayed. When the type of the individual device 12 is selected, a screen for setting basic conditions is displayed. In short, when an administrator is authenticated by a password, the authenticated administrator is permitted to set basic conditions and application conditions using the user interface device 14.

As shown in FIGS. 6 and 7, the screens D11 and D12 for setting the basic conditions include fields F4 and F5 for inputting the basic conditions. 6 and 7 exemplify a screen D11 for setting a reference condition corresponding to the mist generating device 52. FIG. A screen D11 shown in FIG. 6 is a screen for setting a target value, and a field F4 is provided so that three items of “community temperature”, “community humidity”, and “illuminance” can be input for each growth stage. ing. That is, on the screen D11, target values can be set for the environmental elements (temperature and humidity) monitored by the first sensor 11 and the environmental elements (illuminance) monitored by the second sensor 21, respectively. become. A screen D12 shown in FIG. 7 is a screen for setting a reference value, and the field F5 is set so that two items of “spray time” (operation time) and “interval time” can be input for each growth stage. Is provided.

Application conditions are set for each of the two standard values. Therefore, as shown in FIGS. 8 and 9, the screens D13 and D14 for setting application conditions include fields F6 and F7 for inputting adjustment values for the respective reference values. A screen D13 shown in FIG. 8 is a screen for setting an adjustment value for the spraying time. The field F6 is set so that adjustment values corresponding to “moderate”, “standard”, and “more” can be input for each growth stage. Is provided. A screen D14 shown in FIG. 9 is a screen for setting an adjustment value for the interval time. The field F7 is set so that adjustment values corresponding to “moderate”, “standard”, and “large” can be input for each growth stage. Is provided.

When the basic condition and the application condition are input by using the user interface device 14, the basic condition and the application condition are set in the storage unit 135. When the basic condition and the application condition are set in the storage unit 135, the control device 13 can control the individual device 12 using the basic condition and the application condition.

As described above, since the screen for setting the basic condition and the application condition is not displayed unless the password is authenticated, the user of the agricultural house 10 is prevented from changing the basic condition and the application condition by mistake. . That is, it is possible to prevent the plant growth from being adversely affected by arbitrarily changing the basic conditions and the application conditions.

If the control device 13 does not give an instruction, the control device 13 operates the individual device 12 using the basic conditions. On the other hand, by pressing the button B1, the operation of the individual device 12 can be changed using the application conditions. When the button B1 is pressed, a screen D15 including three buttons B11, B12, and B13 is displayed as shown in FIG. Button B11 corresponds to water, button B12 corresponds to light, and button B13 corresponds to ventilation.

When the button B11 is pressed, as shown in FIG. 11, an adjustment value relating to the amount (operation time) and the frequency (interval time) can be used for each of the mist generating device 52 and the watering device 51. Is displayed. That is, for four types of items, a screen including buttons B111, B112, B113, and B114 for selecting “reserved”, “standard”, and “more” is displayed.

In addition, when the button B12 is pressed, a screen (not shown) that allows the adjustment value regarding the closing time zone to be used for the curtain 61 is displayed. Since the curtain 61 is provided for the purpose of controlling the light environment, it is desirable to use expressions of “brighter” and “darker” for “more” and “moderate”. When the button B13 is pressed, a screen (not shown) is displayed that allows adjustment values to be used for the temperature at which the side window 62 is opened and the temperature at which the ventilation fan 63 starts operating. For the side window 62 and the ventilation fan, the temperature for ventilation is set higher when “moderate” is selected, and the temperature for ventilation is set lower when “more” is selected. The screen when the button B12 is pressed and the screen when the button B13 is pressed have different item names from the screen when the button B11 is pressed, and thus the number of buttons is different. This is the same as the screen D16 shown in FIG.

Here, the screen D16 shown in FIG. 11 is taken as an example. On this screen D16, “moderate”, “standard”, or “large” can be selected for the buttons B111, B112, B113, and B114 corresponding to the four types of items. Therefore, it becomes possible to adjust the operation of the watering device 51 and the mist generating device 52 by pressing the buttons B111, B112, B113, B114. That is, by giving an adjustment value through the user interface device 14, the operation of the individual device 12 can be finely adjusted.

As described above, the user can finely adjust the operation content of the individual device 12 without receiving password authentication by pressing the “preference adjustment” button B1. As a result, a user who grows a plant can adjust it according to his / her preference without greatly deviating from the plant growing environment. In addition, since the expression of the adjustment value for the user is not a numerical value but a word such as “moderate”, “standard”, “more”, an intuitive understanding is possible for the user.

When the basic condition and the application condition corresponding to the plant growth stage are set for each type of the individual device 12, the control device 13 controls the individual device 12 according to the basic condition (also using the application condition if necessary). . The control device 13 determines a priority order for operating each facility included in the individual device 12 based on the season and the growth stage of the plant. The priority order is preset in the storage unit 135.

Seasons are usually divided into summer and winter, for example. Moreover, a priority is set to the environmental element to be controlled by a combination of the season and the growth stage. As an example, there are five types of environmental elements: temperature, humidity, moisture (in the soil), illuminance, and day length (day length). Also, humidity and moisture may be handled together, and illuminance and day length may be handled together. That is, there are three types of environmental elements: temperature, humidity / moisture, and illuminance / day length. And the individual apparatus 12 used in order to control these environmental elements is set according to the combination of a season and a growth stage.

The control device 13 is individually arranged for each agricultural house 10, and the configuration for setting the basic condition and the application condition as described above and instructing the adjustment value to adjust the operation of the individual device 12 is independent. It can also be used in the agricultural house 10. In other words, the control using the basic condition and the application condition can be used not only in the plurality of agricultural houses 10 but also in the single agricultural house 10.

As described above, it is desirable that the plant growing system includes the user interface device 14 including the display device 141 and the operation device 142. In this case, the storage unit 135 stores basic conditions including a reference value related to the control content of the individual device 12 and application conditions including an adjustment value that is increased or decreased with respect to the reference value. The processing unit 130 determines the control content of the individual device 12 based on the reference value and the adjustment value stored in the storage unit 135 and the instruction from the user interface device 14. Furthermore, the processing unit 130 authenticates the administrator using the user interface device 14, and when the administrator is authenticated, allows the setting of basic conditions and application conditions, and stores the set basic conditions and application conditions. It is desirable to be configured to store in the unit 135.

Further, the individual device 12 may be configured to be controlled by determining respective times of operation and non-operation. In this case, it is desirable that the processing unit 130 is configured to determine respective times of operation and non-operation of the individual device 12 based on the reference value, the adjustment value, and an instruction from the user interface device 14.

The basic condition may include a target value maintained by the operation of the individual device 12 with respect to the environmental element monitored by the first sensor 11. In this case, the processing unit 130 is configured to permit setting of the target value and store the set target value in the storage unit 135 when the administrator is authenticated using the user interface device 14. It is desirable.

Further, the basic condition may include a target value that is maintained by the operation of the individual device 12 regarding the environmental element monitored by the second sensor 21. In this case, the processing unit 130 is configured to permit setting of the target value and store the set target value in the storage unit 135 when the administrator is authenticated using the user interface device 14. It is desirable.

These configurations prevent the user from directly changing the contents of the basic conditions and application conditions when trying to change the control contents of the individual device 12. Since the user is only allowed to increase or decrease the adjustment value with respect to the reference value, the user can adjust the plant growth environment within a range that does not cause unintended adverse effects. Moreover, since only the administrator is permitted to change the basic condition and the application condition, it is possible to prevent the user from changing the basic condition and the application condition by mistake.

Incidentally, as described above, the “temporary operation” button B4 is arranged at the bottom of the basic screen D10 shown in FIG. When the individual device 12 is temporarily operated using the button B4, the individual device 12 affects the first group using water (for example, the watering device 51 and the mist generating device 52) and the environment without using water. Are divided into two groups (for example, the curtain 61, the side window 62, and the ventilation fan 63). That is, the individual device 12 is divided into a group (first group) that is the individual device 12 that uses water and a group (second group) that is the individual device 12 that does not use water. However, the individual devices 12 can be further divided into a large number of groups. Each group includes a plurality of individual devices 12 in principle.

When the button B4 is pressed on the basic screen D10 of FIG. 5, as shown in FIG. 12, a button B21 labeled “collective operation” and a button B22 labeled “individual operation” for each group of individual devices 12. A screen D17 on which is arranged is displayed. The button B21 is pressed when the individual devices 12 included in the group are collectively operated, and the button B22 is pressed when the specific individual devices 12 included in the group are individually operated.

Here, the operation of the control device 13 includes an automatic mode for controlling the operation of the individual device 12 in accordance with basic conditions (according to the application conditions when application conditions are set), and a stop mode for temporarily stopping the automatic mode. There is. That is, the button B21 and the button B22 are operated when the individual device 12 is shifted to the stop mode.

When the “batch operation” button B21 is pressed on the screen D17 shown in FIG. 12, a screen D18 for setting the time is displayed as shown in FIG. A screen D18 shown in FIG. 13 includes a field F21 for setting the duration time of the individual device 12 in the stop mode. When the time is set in the field F21 and the “Input” button B23 is pressed, the time for which the individual device 12 belonging to the corresponding group is kept in the stop mode is set in the storage unit 135. Hereinafter, this time is referred to as “set time”. The set time is set to about 30 minutes to 1 hour, for example.

In the lower part of the screen D18 shown in FIG. 13, a button B24 labeled “automatic” and a button B25 labeled “stop” are arranged. When the time for applying the stop mode to the individual devices 12 belonging to the corresponding group is set in the storage unit 135 and the button B25 is pressed, the control device 13 maintains the stop mode for the set time. After that, the stop mode is automatically canceled to return to the automatic mode. In this case, during the period of shifting to the stop mode, the individual devices 12 belonging to the group collectively stop the operation. The control device 13 counts down during the period when the button B25 is pressed and the stop mode is executed. A screen D18 shown in FIG. 13 is provided with a field F22 for displaying a time until the stop mode is canceled, and the control device 13 displays a value during countdown in the field F22.

Also, when the “automatic” button B24 is pressed during the period of the stop mode, the stop mode is canceled and the automatic mode is restored. That is, even when the stop mode is selected and the set time has elapsed, when the button B24 is pressed, the processing unit 130 returns to the automatic mode.

When the “individual operation” button B22 is pressed on the screen D17 shown in FIG. 12, as shown in FIG. 14, buttons corresponding to the individual devices 12 constituting the group selected on the screen D17 shown in FIG. A screen D19 in which B31 and button B32 are arranged is displayed. In the illustrated example, the individual device 12 is a mist generating device 52 and a watering device 51, the button B31 corresponds to the mist generating device 52, and the button B32 corresponds to the watering device 51. When the button B31 is pressed, the screen shifts to a screen D20 shown in FIG.

This screen D20 has the same contents as the screen D18 shown in FIG. 13, but only the mist generating device 52 is targeted. Further, a button B33 and a button B34 for selecting the individual devices 12 belonging to the same group are arranged at the lower part of the screen D20 shown in FIG. In the illustrated example, the button B33 corresponds to the mist generating device 52, and the button B34 corresponds to the watering device 51. Therefore, on the screen D20 shown in FIG. 15, when the button B34 is pressed, the screen is switched to a screen only for the watering device 51 with the same contents. That is, after setting the stop mode duration for the mist generating device 52 by pressing the button B34, the stop mode duration for the watering device 51 is set without returning to the screen D19 shown in FIG. It becomes possible to do. In the stop mode, the designated individual device 12 stops operation for a set time for each individual device 12.

Here, when the “automatic” button B24 is pressed during the stop mode, the stop mode is canceled and the automatic mode is restored. At this time, even if the plurality of individual devices 12 are in the stop mode, when the button B24 is pressed, the processing unit 130 returns to the automatic mode, and as a result, all the individual devices 12 are collectively in the automatic mode. To be controlled.

As described above, the stop mode is limited to the set time for the duration of the stop mode, so it automatically returns from the temporarily selected stop mode to the automatic mode. Therefore, even if the user forgets to return to the automatic mode, the control device 13 can return to the automatic mode when the set time elapses and maintain the plant growth environment. Further, it is possible to return to the screen D17 shown in FIG. 12 within a set time during which the stop mode is continued (pressing a “return” button arranged in the upper right corner of each screen). Therefore, within the set time, by pressing the “collective control” button B21 or the “individual control” button B22 on the desired individual device 12 from the screen D17, the desired individual device 12 is subjected to collective control or individual control. It becomes possible to do.

Not only the control using the basic conditions and the application conditions, but also the operation using the “temporary operation” button B4 can be used in the single agricultural house 10 instead of the multiple agricultural houses 10. That is, since the control device 13 is individually arranged for each agricultural house 10, the operation of temporarily selecting the stop mode from the automatic mode can also be used in the single agricultural house 10.

As described above, it is desirable for the processing unit 130 to select the operation between the automatic mode and the stop mode. In the automatic mode, the processing unit 130 operates the individual device 12 with the control content determined by the reference value and the adjustment value stored in the storage unit 135 and the instruction from the user interface device 14. In the stop mode, the processing unit 130 stops the operation in the automatic mode for the set time specified by the user interface device 14 for the individual device 12 specified by the user interface device 14 and then returns to the automatic mode.

Further, the processing unit 130 may have a configuration in which a plurality of predetermined types of individual devices 12 are collectively specified in the stop mode. The processing unit 130 may be configured so that the set time can be specified for each individual device 12 within the set time of the stop mode. The processing unit 130 may be configured so that a set time can be specified for a plurality of types of individual devices 12 determined in advance within the set time of the stop mode.

With such a configuration, even if the automatic mode in which the individual device 12 is automatically operated is temporarily stopped, the automatic mode is automatically restored, so that the automatic mode continues to stop so that the plant growing environment is maintained. It is possible to prevent a significant change.

By the way, plants grown in each agricultural house 10 may be different, and a relatively large variation may occur in the amount of solar radiation in each agricultural house 10 due to seasonal variation. In these cases, it may be a more suitable condition for plant growth if each agricultural house 10 controls the individual device 12 without using the input information from the second sensor 21.

In preparation for such a case, it is desirable that the control device 13 can select not only the first state that cooperates with the control device 13 of the other agricultural house 10 but also the second state that does not cooperate. Therefore, as described above, the control device 13 includes the switching unit 134 that switches between the first state and the second state. The switching unit 134 includes a switch (not shown) so that the user can manually select the first state and the second state.

If the user selects the first state with the switching unit 134, the second sensor 21 and the shared device 22 can be shared by the multiple agricultural houses 10. In addition, if the user selects the second state by the switching unit 134, the individual device 12 can be controlled independently for each agricultural house 10 by the input information from the first sensor 11. Moreover, since the control apparatus 13 which communicates with the 2nd sensor 21 and the shared apparatus 22 shares input information with the other control apparatus 13, the 2nd sensor 21 and the shared apparatus 22 are which agricultural house 10 of which. It may be connected to the control device 13. Therefore, even when the second sensor 21 or the shared device 22 is moved in the state where the agricultural house 10 is installed, the second sensor 21 or the shared device may be connected to the control device 13 at a place where it can be easily connected. The position of the device 22 can be easily changed.

According to the configuration of the present embodiment, there is no need to provide a shared control device (for example, a shared panel) to which the second sensor 21 and the shared device 22 are connected, and the control installed in each agricultural house 10. The second sensor 21 and the shared device 22 can be used only by the device 13. Therefore, compared to a configuration using a shared control device, it is easy to change the wiring routing when moving the second sensor 21 or the shared device 22, and the construction cost can be reduced. Further, when a shared control device is used, if the control device fails, the second sensor 21 and the shared device 22 cannot be used in all the agricultural houses 10. On the other hand, in the configuration of the present embodiment, even if the control device 13 to which the second sensor 21 and the shared device 22 are connected fails, the second sensor 21 and the shared device 22 are connected to other control devices 13. In other agricultural houses 10, the environment can be maintained. Therefore, it becomes possible to limit the damage of plants to only one building.

The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
