Description

Agricultural house environment adjustment system

The present invention relates to an environment adjusting system for an agricultural house.

　House cultivation that grows crops using agricultural houses requires various devices. Examples of such a device include, for example, a carbon dioxide supply device for promoting photosynthesis necessary for plants, and a skylight for controlling the growth of plants by discharging oxygen in the greenhouse to the outside or blocking light. Ventilators, devices with curtain opening/closing mechanisms, sprinklers for sprinkling water, sprayers for sprinkling fertilizer, and the like. These devices are separately provided one by one, and each has a sensor and a control device. Therefore, when controlling the operation of these devices, it is necessary to individually give an operation instruction to each of these devices, which is complicated. In order to solve this point, there is a complex environment control device that can be controlled in one place (for example, Patent Document 1 below).

Patent No. 6277159

However, the above-mentioned combined environment control device can only control the heaters, skylights, curtains, etc. determined in advance. In other words, the output destination cannot be selected for the controlling controller. Moreover, since the above-mentioned composite environment control device is premised on being used for a relatively large house, it includes many functions that are unnecessary when used for a relatively small house (for example, a kamaboko type house). .. As described above, in the above-described complex environment control device, there is a function that becomes unnecessary depending on the scale of the house to be used, and further, another function cannot be added later. Therefore, the inventor of the invention according to the present application considers a mechanism that can control a plurality of devices in one place (environmental adjustment system of an agricultural house) and a controller that can use only necessary functions when necessary. It was

Furthermore, in greenhouse cultivation, which costs more than anything else, it is important to make the above controllers cheaper. Therefore, an inexpensive controller is provided by reducing the number of terminals connecting the above-mentioned devices. In particular, the Raspberry Pi and Arduino (registered trademark) are also known as cheap microcomputers. Even if the number of required devices increases, it is a cheap controller, so it is enough to add them.

On the other hand, it suffices if the necessary information can be acquired on the screen of the mobile terminal and the device can be operated only when necessary. If you wirelessly instruct the controller, the device will move automatically. ：

Furthermore, by adding a SIM communication function to the controller, data can be browsed from remote locations via the Internet.

The present invention relates to an environment control system for an agricultural house, which is an agricultural house in which three sensors, a temperature sensor, a humidity sensor, and a carbon dioxide sensor are installed, and a fine fog device and a lighting device installed in the agricultural house. , Environment control devices such as ventilation windows, blackout curtains, heaters, CO ₂ generators, etc., and up to four environment control devices can be arbitrarily selected to connect with the selected environment control device with a cable. There is a controller that has a contact output unit that can perform wireless communication, and a mobile terminal that can be wirelessly connected to a LAN. There is a terminal that can read the values measured from three sensors on the mobile terminal side. When reaching the preset conditions from the terminal for each of carbon dioxide concentration and satiation, any or all of the functions of up to four environmental control devices selected and connected by a cable are turned on or off. This enabled a total of 16 combinations.

In addition, the above-mentioned environment adjustment system enables selection of two out of four among temperature, humidity, carbon dioxide concentration, and satiation, thereby enabling the above 16 combinations×6 (= ₄ C ₂ )=96 combinations. You may make it possible to set the parameter. Moreover, the controller of the above-mentioned environment adjustment system may combine any one or both of a solar radiation sensor and a moisture soil sensor.

According to the present invention, a plurality of environment adjusting devices can be controlled in one place. Further, according to the present invention, it is possible to use a required function when a plurality of environment adjustment devices have the required function. Furthermore, according to the present invention, it is possible to provide an environment adjustment system that achieves the above effects at low cost.

It is a figure which shows typically an example of a structure of the environment adjustment system which concerns on embodiment. It is a figure which shows the structure of the controller 30 of FIG. It is a figure which shows an example of setting of control conditions. It is a figure which shows the combination of "ON" and "OFF". It is a figure which shows typically the structure containing the controller which concerns on a modification.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to this. Further, in the drawings, in order to explain the embodiment, a part of the drawing is enlarged or emphasized, and the scale is appropriately changed. FIG. 1 is a diagram schematically illustrating an example of the configuration of the environment adjustment system 100 according to the embodiment.

The environment adjustment system 100 according to the embodiment is an environment adjustment system for an agricultural greenhouse, and is used for greenhouse cultivation for growing crops in an agricultural greenhouse. As shown in FIG. 1, the environment adjustment system 100 includes an agricultural house 10, an environment adjustment device 20, a controller 30, and a mobile terminal 40. The environment adjustment system 100 includes one agricultural house 10, one controller 30, and one mobile terminal 40.

The agricultural house 10 is a house used for greenhouse cultivation. The agricultural house 10 is, for example, a so-called vinyl house (also called a plastic house or a green house). The agricultural house 10 has an arbitrary shape, but is, for example, a semi-cylindrical type formed by stretching a synthetic resin film in an arch shape on a body such as steel. The agricultural house 10 may have any size, and may be a small one for home use or a large one for agriculture. For example, the width is about 5 m to 10 m and the depth is about 5 m to 10 m. ..

The agricultural house 10 is provided with three types of sensors, a temperature sensor 11, a humidity sensor 12, and a carbon dioxide sensor 13. These sensors are suspended on the inner wall of the agricultural house 10, for example. Further, each of these three sensors is physically connected to the controller 30 via the

communication cables

41, 42, 43, and can communicate with the controller 30. Note that some or all of the above-mentioned three sensors may not be connected to the communication cable 41 or the like. When the sensor is not connected to the communication cable 41 or the like, communication from the sensor to the controller 30 may be performed using various wireless technologies such as Bluetooth (registered trademark), Wi-Fi, or public wireless communication.

The temperature sensor 11 is a sensor that detects the temperature of air, and is used to measure the temperature (air temperature) of the air in the cultivation space 10 a of the agricultural house 10. The humidity sensor 12 is a sensor that detects the humidity of the air, and is used to measure the humidity of the air in the cultivation space 10a. The carbon dioxide sensor 13 is a sensor for detecting carbon dioxide (CO ₂ ) in the air, and is used to measure the concentration of carbon dioxide in the air in the cultivation space 10a. The temperature sensor 11 and the humidity sensor 12 are also used to measure the difference in air saturation in the cultivation space 10a. The satiation is an index showing how much room for water vapor to enter in air at a certain temperature and humidity. Specifically, the satiation means the difference between the saturated water vapor amount at the present temperature and the present vapor pressure of the air, such as the free space of the vapor per 1 m ^{3 of} air expressed in g. The satiation is calculated, for example, as follows based on the temperature and humidity (relative humidity) of the air in the cultivation space 10a.
When the temperature of the air in the cultivation space 10a is T° C., the water vapor pressure e(T) is calculated by the following equation (1).
e(T)=6.1078×10^(7.5T/(T+237.3))...(1)
The saturated water vapor amount VH is calculated by the following equation (2).
VH=217×e(T)/(T+273.15)...(2)
Here, assuming that the relative humidity of the air in the cultivation space 10a is R, the saturation difference HD is calculated by the following equation (3).
HD=(100-R)×VH/100 (3)
It is said that the satiation difference HD of about 3 to 6 g/m ³ is suitable for photosynthesis of cultivated crops.

The environment adjustment device 20 is a device that adjusts the state of the air in the cultivation space 10a. The environment adjustment system 100 includes a total of four environment adjustment devices 20 including a ventilation window 21, a light-shielding curtain 22, a heater 23, and a CO ₂ generator 24. These four environment adjusting devices 20 are connected to the controller 30 via

cables

51, 52, 53, 54, respectively, and can communicate with the controller 30.

The ventilation window 21 is a window for ventilating the cultivation space 10a. The cultivation space 10a is ventilated by opening the ventilation window 21. The ventilation window 21 is openably and closably attached to the outer wall portion or the ceiling portion of the agricultural house 10.

The light-blocking curtain 22 is a curtain that blocks light such as sunlight that enters the cultivation space 10a. By closing the light-shielding curtain 22, the cultivation space 10a is shielded from light, and the effects of heat insulation and heat retention can be expected. The light-shielding curtain 22 is made of, for example, a fine mesh mesh and colored film material or sheet material. For example, one end of the light-shielding curtain 22 is fixed to the agricultural house 10, and a shaft member is attached to the other end thereof. The shaft member is movable on the back side of the ceiling of the agricultural house 10 along a guide rail or the like provided substantially horizontally or along the inclination of the ceiling. When not in use, the light-shielding curtain 22 is housed in a state of being wound around the shaft member, and when in use, the shaft member automatically moves along the guide rails so that it can be expanded so as to cover the cultivation space 10a from above.

The heater 23 generates heat by burning fuel such as kerosene or heavy oil, and supplies this to the cultivation space 10a. By operating the heater 23, the temperature of the cultivation space 10a can be raised.

The CO ₂ generator 24 generates carbon dioxide gas necessary for photosynthesis, which is a growing process of cultivated crops, and supplies this to the cultivation space 10a. By operating the CO ₂ generator 24, the concentration of carbon dioxide in the cultivation space 10a can be improved.

In the environment adjustment system 100 according to the embodiment, a total of four ventilation windows 21, a light-shielding curtain 22, a heater 23, and a CO ₂ generator 24 are selected as the environment adjustment devices 20. The four environment adjusting devices 20 are connected to the controller 30 via

cables

51, 52, 53, 54, respectively. Here, the number of environment adjustment devices 20 selected in the environment adjustment system 100 is not limited to four, and may be one, two, or three. That is, in the environment adjustment system 100, the number of environment adjustment devices 20 connected to the controller 30 via the cable 51 or the like may be appropriately one, two, or three. For example, the environment adjustment device 20 included in the environment adjustment system 100 may be the ventilation window 21 only, or may be the ventilation window 21 and the heater 23, or the ventilation window 21, the light shielding curtain 22, and the heater 23. It may be three.

Further, the environment adjusting device 20 included in the environment adjusting system 100 is not limited to the ventilation window 21, the light shielding curtain 22, the heater 23, and the CO ₂ generator 24, and the ventilation window 21, the light shielding curtain 22, and the heater. 23, and any one or more of the CO ₂ generator 24, for example, to other environment adjustment device 20, such as a fine mist device, a heat retaining curtain, a lighting device, a watering device, a skylight ventilation device, a fertilizer spraying device. It may be replaced. The fine mist device is an environment adjustment device that improves the humidity of the air in the cultivation space 10a by spraying water from a nozzle installed in the cultivation space 10a. Like the light-shielding curtain 22, the heat-retaining curtain is an environment adjusting device that is used in an expanded state to keep the air in the cultivation space 10a warm. The lighting fixture is an environment adjusting device that changes the environment of the cultivation space 10a so as to promote the photosynthesis of the cultivated crop by making the cultivation space 10a bright.

The controller 30 has four terminals 30a, 30b, 30c, 30d for physically connecting to the environment adjusting device 20. These four terminals 30a, 30b, 30c, 30d are connected to

cables

51, 52, 53, 54, respectively. The controller 30 can connect the selected environment adjusting device 20 to the cable 51 or the like by arbitrarily selecting up to four of the environment adjusting devices 20. The controller 30 has only four terminals 30a and the like for connecting to the environment adjusting device 20, and thus has a simple configuration and can be provided at low cost.

The controller 30 is equipped with a SIM communication function, and data can be browsed from remote locations via the Internet. Further, the controller 30 can wirelessly communicate with the mobile terminal 40 via a LAN (Local Area Network).

2 is a diagram showing a configuration of the controller 30 of FIG. As shown in FIG. 2, the controller 30 has a contact output unit 31, an instruction unit 32, an input unit 33, a processing unit 34, a transmission unit 35, and a storage unit 36. The instruction unit 32, the input unit 33, and the processing unit 34 are, for example, a configuration of a single board computer including an inexpensive microcomputer such as a Raspberry Pi and an Arduino (registered trademark).

The contact output part 31 has a total of four contact parts, namely a first contact part 31a, a second contact part 31b, a third contact part 31c, and a fourth contact part 31d. These first to fourth contact portions 31a to 31d are configured to output contact outputs of ON and OFF, respectively. That is, the first to fourth contact portions 31a to 31d are opened and closed by a mechanical relay that mechanically opens and closes the contact portions, thereby performing ON or OFF contact output. The opening/closing operation of the first to fourth contact points 31a to 31d is executed based on an instruction from the processing section 34.

The first contact portion 31 a is physically connected to the CO ₂ generator 24 via the cable 54. Here, the first contact part 31a controls the operation of the CO ₂ generator 24 in two stages of ON and OFF by its opening/closing operation. For example, a CO ₂ generator 24 by the ON contact output at the first contact portion 31a and the operation state, the operation stop state of CO ₂ generator 24 by the OFF contact output at the first contact portion 31a To do.

The second contact portion 31b is physically connected to the heater 23 via the cable 53. Here, the second contact portion 31b controls the operation of the heater 23 in two stages of ON and OFF by its opening/closing operation. For example, the heater 23 is brought into an operating state by turning on the contact output at the second contact portion 31b, and the heater 23 is put into an operation stop state by turning off the contact output at the second contact portion 31b.

The third contact portion 31c is physically connected to the light-shielding curtain 22 via the cable 52. Here, the third contact portion 31c controls the operation of the light-shielding curtain 22 in two stages of ON and OFF by its opening/closing operation. For example, by turning on the contact output at the third contact portion 31c, the light-shielding curtain 22 is put into a use state (in an expanded state), and by turning off the contact output at the third contact portion 31c, the light-shielding curtain 22 is not used. (Stored state).

The fourth contact portion 31d is physically connected to the ventilation window 21 via the cable 51. Here, the fourth contact part 31d controls the operation of the ventilation window 21 in two stages of ON and OFF by its opening/closing operation. For example, the ventilation window 21 is opened by turning on the contact output of the fourth contact portion 31d, and the ventilation window 21 is closed by turning off the contact output of the fourth contact portion 31d.

The instruction unit 32 instructs the contact output unit 31 to open and close each contact based on the control information CI determined by the processing unit 34.

The measured values are input to the input unit 33 from the temperature sensor 11, the humidity sensor 12, and the carbon dioxide sensor 13, respectively. The measurement values (temperature, humidity, and carbon dioxide concentration) measured by the temperature sensor 11, the humidity sensor 12, and the carbon dioxide sensor 13 are cultivation space environment information SI.

Further, the control condition information CO for controlling the operation of the environment adjustment device 20 is input to the input unit 33. The control condition information CO is information relating to the condition that each contact output in the first to fourth contact parts 31a to 31d is ON or OFF. That is, conditions such as when to turn ON or OFF the contact output of the contact output unit 31 are input to the input unit 33 as the control condition information CO. The control condition information CO is input by the user in advance via the mobile terminal 40.

The processing unit 34 first calculates the satiety difference of the air in the cultivation space 10a based on the temperature and humidity data (measured values) in the cultivation space environment information SI. Next, the processing unit 34 outputs the contact point in the contact point output unit 31 according to the condition of the control condition information CO based on the cultivation space environment information SI (data of temperature, humidity, and carbon dioxide concentration) and the calculated difference in saturation. "ON" or "OFF"). That is, the processing unit 34 determines whether to turn ON or OFF the contact output of each contact unit 31a based on the four parameters of the temperature, humidity, carbon dioxide concentration of the air in the cultivation space 10a, and the satiation, It is determined according to the condition of the control condition information CO. The information of ON or OFF of the contact output determined by the processing unit 34 here is the control information CI.

The transmitting unit 35 transmits the cultivation space environment information SI, information regarding the operating state of the environment adjusting device 20, and the like to the mobile terminal 40. It may be transmitted to the mobile terminal 40 when there is a browsing request from the mobile terminal 40, or may be automatically transmitted periodically or constantly even without such a browsing request. In addition, in the environment adjustment system 100, it is assumed that the user browses information such as the cultivation space environment information SI using the mobile terminal 40. Therefore, the controller 30 does not have a display function of the cultivation space environment information SI. However, the function of displaying the cultivation space environment information SI may be provided in the controller 30 in addition to the mobile terminal 40.

The storage unit 36 stores the above-mentioned cultivation space environment information SI, control condition information CO, control information CI, programs necessary for the operation of the contact output unit 31, and the like. The storage unit 36 is a volatile memory such as a RAM, a non-volatile memory such as a flash memory, an EPROM, or an EEPROM.

The mobile terminal 40 is a terminal that can be carried by humans, and is, for example, a smartphone or a tablet terminal. The mobile terminal 40 is connected to the controller 30 via a wirelessly connectable LAN so as to be capable of mutual communication. The mobile terminal 40 may have a SIM communication function for connecting to a wireless LAN. The mobile terminal 40 has a display screen 40a capable of displaying information such as the cultivation space environment information SI received from the controller 30 (see FIG. 1). The display screen 40a is, for example, a display such as liquid crystal or organic EL. The user can browse the cultivation space environment information SI using the mobile terminal 40a. This allows the user to understand the environment of the cultivation space 10a even when the user is away from the agricultural house 10 and the controller 30. Further, the mobile terminal 40 has an input unit for the user to input the control condition information CO. When the control condition information CO is input, the mobile terminal 40 transmits the input control condition information CO to the controller 30.

Next, an example of the operation of the environment adjustment system 100 when the user adjusts the environment of the cultivation space 10a using the environment adjustment system 100 will be described.

The user sets control conditions for the environment adjustment device 20 in the environment adjustment system 100. The control condition is a condition for turning on/off the functions of the ventilation window 21, the light-shielding curtain 22, the heater 23, and the CO ₂ generator 24. The control conditions are set for the purpose of adjusting the cultivation space 10a to a desired environment suitable for cultivation. The control conditions are determined according to, for example, the type of the crop to be cultivated, the variety, the climate of the installation place of the agricultural house 10, and the like. The control condition is set by the user inputting the control condition from the mobile terminal 40. At this time, the user may set the control conditions while appropriately referring to the cultivation space environment information SI displayed on the mobile terminal 40. The information about the control conditions set here becomes the above-mentioned control condition information CO.

The control condition is individually set for each of the four environment adjusting devices 20. For example, (a) the condition that the function of the ventilation window 21 is turned on (that is, the condition that the ventilation window 21 is opened), and (ii) the condition that the function of the light-shielding curtain 22 is turned on (that is, the light-shielding curtain 22 is expanded). State), (c) a condition for turning on the function of the heater 23 (that is, a condition for turning on the heater 23), and (d) a condition for turning on the function of the CO ₂ generator 24 (that is, CO ₂ ) The conditions (a) to (d) for setting the operation state of the generator 24 are set. However, the control conditions may be set collectively for a plurality of environment adjustment devices 20. For example, the conditions (c), (d), and (e) that both the functions of the ventilation window 21 and the light shielding curtain 22 are both in the ON state (that is, the ventilation window 21 is open and the light shielding curtain 22 is expanded). The above conditions (c) to (e) may be set. Further, as the control condition, a condition for turning off the function may be set instead of a condition for turning on the function of the environment adjusting device 20. In this case, the function of the environment adjusting device 20 is inevitably turned on when the condition for turning off is deviated.

Here, the control condition for controlling the function of each environment adjustment device 20 to be in the ON (or OFF) state is any one of four "temperature", "humidity", "carbon dioxide concentration", and "saturation". It is an environmental condition set based on one measured value. For example, the control condition for turning on the function of the ventilation window 21 in (a) above is set only on the basis of “temperature”, and may be an environmental condition of a predetermined temperature or higher. Further, for example, the control condition for turning on the function of the ventilation window 21 in (d) above is set based only on “humidity”, and may be an environmental condition of a predetermined humidity or higher. Further, for example, the control condition for turning on the function of the CO ₂ generator 24 in the above (d) is set only based on the “carbon dioxide concentration”, and even if the environmental condition is a predetermined concentration or less. Good.

In addition, the control condition (environmental condition) for turning on or off the function of each environment adjustment device 20 is one of four "temperature", "humidity", "carbon dioxide concentration", and "saturation difference". It may be set based on any two measured values. For example, the user selects “temperature” and “humidity” from the four control conditions for turning on the function of the ventilation window 21 (a), which are temperature, humidity, carbon dioxide concentration, and satiation. You may set it. For example, as shown in FIG. 3, for “temperature” and “humidity”, there are two environmental conditions of “25° C. or higher” and “70% or higher” (“first condition” and “second condition” in FIG. 3). ) Is set, and the function of the ventilation window 21 is turned on when both of these two environmental conditions are satisfied. In this case, the controller 30 acquires information on the temperature and humidity of the cultivation space, and the contact output unit turns on the function of the ventilation window 21 when the temperature is 25° C. or higher and the humidity is 70% or higher. 31 (4th contact part 31d) is instructed. In addition, for example, regarding the control conditions for turning on the function of the ventilation window 21 in (a) above, environmental conditions such that "temperature" is a temperature within a predetermined range and "carbon dioxide concentration" is within a predetermined range, As the control conditions for turning on the function of the light-shielding curtain 22 in (a) above, environmental conditions such as “humidity” being a predetermined humidity or more and “saturation difference” being a predetermined value or more are set.

Furthermore, the control condition for turning on or off the function of each environment adjustment device 20 is any one of the four "temperature", "humidity", "carbon dioxide concentration", and "saturation difference". You may set based on a measured value. For example, the control condition for turning on the function of the ventilation window 21 in (a) above may be set based on, for example, three measured values of “temperature”, “humidity”, and “carbon dioxide concentration”. Of course, in this case, the environmental conditions may be a predetermined temperature or higher, a predetermined humidity or higher, and a predetermined carbon dioxide concentration or higher.

Furthermore, all four measured values of "temperature", "humidity", "carbon dioxide concentration", and "saturation difference" are control conditions for turning on (or off) the function of each environment adjustment device 20. It may be set based on. For example, the control condition for turning on the function of the light-shielding curtain 22 in (a) above is an environmental condition of a predetermined temperature or higher, a predetermined humidity or higher, a predetermined carbon dioxide concentration or higher, and a predetermined saturated difference value or higher. It may be.

When the setting of the control conditions by such a user is completed, the controller 30 acquires the cultivation space environment information SI and controls each contact part 31a or the like according to the control condition information CO based on the acquired cultivation space environment information SI. ..

In the present embodiment, when the function of a predetermined environment adjustment device 20 (for example, the ventilation window 21) is turned on (expanded state), the instruction unit 32 of the controller 30 causes the environment adjustment device 20 (for example, the ventilation window 21). ) Is sent to the contact portion (for example, the first contact portion 31a) connected to (1). Then, the contact portion (for example, the first contact portion 31a) that receives the signal closes the contact and turns on the contact output. As a result, the environment adjusting device 20 (for example, the ventilation window 21) is in the ON state. On the other hand, when the function of the predetermined environment adjustment device 20 (for example, the ventilation window 21) is turned off (stored), the instruction unit 32 of the controller 30 is connected to the environment adjustment device 20 (for example, the ventilation window 21). The open signal is sent to the contact portion (for example, the first contact portion 31a). Then, the contact portion (for example, the first contact portion 31a) that receives the signal opens the contact and turns off the contact output. As a result, the function of the environment adjusting device 20 (for example, the ventilation window 21) is turned off.

By such control of the controller 30, the function of each of the four environment adjusting devices 20 is appropriately turned on or off. As a result, the environment of the cultivation space 10a is automatically adjusted. By browsing the cultivation space environment information SI and the like displayed on the mobile terminal 40, the user can appropriately confirm whether or not the environment of the cultivation space 10a is adjusted to a desired environment.

Here, as shown in FIG. 4, there are 16 combinations of (1) to (16) in the “ON” and “OFF” states of the four environment adjusting devices 20. As described above, in the environment adjustment system 100, the environment of the cultivation space 10a can be adjusted by 16 kinds of outputs of 16 ways at the maximum.

Therefore, the user can previously set the control conditions for each of the 16 stages of output ((1) to (16) in FIG. 4). That is, for example, the control condition (for example, when the temperature is equal to or higher than a predetermined temperature) to be the output of (1) shown in FIG. 4 (that is, the state where all the functions of the four environment adjusting devices 20 are “ON”), The output of (2) of FIG. 4 (that is, the functions of the ventilation window 21, the light-shielding curtain 22, and the heater 23 are all “ON”, and the function of the CO ₂ generator 24 is “OFF”). It is possible to set control conditions and the like. That is, it is possible to set 16 kinds of control conditions corresponding to the above 16 stages of output. In this case, the 16 control conditions are always set so as to correspond to a deviation or one of these control conditions. It should be noted that each of the conditions is set for the output of 15 steps out of the output of 16 steps (for example, (1) to (15) in FIG. 4), and if all of the 15 conditions are not satisfied, the remaining 1 is left. One output may be set (for example, all (16) in FIG. 4 is in the “OFF” state).

As described above, each of the 16-step output control conditions is based on any one of the four measured values of "temperature", "humidity", "carbon dioxide concentration", and "saturation difference". It may be set, may be set based on any two or three, or may be set based on all four measured values. Here, in the case of selecting and setting any two of the four measurement values of “temperature”, “humidity”, “carbon dioxide concentration”, and “saturation difference” for each of the above 16-step control conditions, The control conditions of the environment adjustment system 100 can be set in a maximum of 16 stages×6 (= ₄ C ₂ )=96 combinations. Note that “ ₄ C ₂ ”is the number of methods (combinations) for selecting two from four different ones.

According to such an environment adjustment system 100, a plurality of environment adjustment devices 20 can be controlled at one place. In addition, according to the environment adjustment system 100, it is possible to use the necessary functions of the plurality of environment adjustment devices 20 when necessary. Further, according to the environment adjustment system 100, the controller 30 has only four terminals 30a and the like that are connected to the environment adjustment device 20, and has a simple configuration in which control is performed by ON or OFF contact output. The environment adjustment system 100 can be provided at low cost. Further, according to the environment adjustment system 100, if the controller 30 is wirelessly instructed, the device automatically moves. Further, in the environment adjustment system 100, by providing the controller 30 with the SIM communication function, data can be browsed from a remote place via the Internet.

As described above, the controller 30 of the environment adjustment system 100 includes four terminals 30a and the like, and can control up to four environment adjustment devices 20. Further, in the environment adjusting system 100, the user can appropriately select such four environment adjusting devices 20. Therefore, the user can also select four of the above-described four environment adjusting devices 20 in descending order of necessity according to the degree of contribution to the growth of the cultivated crop, the frequency of use, and the like. By the way, when the number of terminals 30a for connection with the environment adjusting device 20 in the controller is set to three or less, it becomes impossible to connect all of the environment adjusting devices particularly important in greenhouse cultivation due to lack of terminals. there is a possibility. However, since the controller 30 of the environment adjustment system 100 includes the four terminals 30a, it is possible to further avoid the situation where such terminals are insufficient. On the other hand, when the number of terminals for connection to the environment adjusting device 20 in the controller is set to five or more, there is a possibility that the fifth and subsequent terminals are not used and become redundant equipment. That is, in greenhouse cultivation, various environment adjusting devices for greenhouse cultivation such as ventilation windows and light-shielding curtains are installed depending on the scale and installation location of the agricultural house 10, the type and variety of cultivated crops, etc. Not all the functions that the various environment adjusting devices have are required, and as a result, the number of the seed environment adjusting devices 20 connected to the controller 30 may decrease, and excess terminals may occur. However, since the controller 30 of the environment adjustment system 100 includes only four terminals 30a, it is possible to suppress the surplus occurrence of the terminals 30a. As described above, according to the configuration of the controller 30 of the environment adjustment system 100, the provision of the four terminals 30a to 30d effectively controls the cultivation environment while suppressing the excess equipment and reducing the equipment cost. It becomes possible.

Further, the controller 30 has only four terminals 30a itself, and can control only a maximum of four environment adjusting devices 20 by their ON or OFF contact outputs, but as described above, it has 16 ways of 16 stages. By controlling the output, the environment of the cultivation space 10a can be finely adjusted.

Next, a modified example of the controller 30 described above will be described. In the following description, the same or equivalent components as those of the controller 30 described above are designated by the same reference numerals, and the description thereof will be omitted or simplified. FIG. 5: is a figure which shows typically the structure containing the controller 230 which concerns on a modification. As shown in FIG. 5, in addition to the four sensors of the temperature sensor 11, the humidity sensor 12, the carbon dioxide sensor 13, and the satiety sensor 14, the controller 230 further includes both the solar radiation sensor 14 and the moisture soil sensor 15. Is physically connected to. The solar radiation sensor 14 and the water/soil sensor 15 are physically connected to the controller 230 via the

communication cables

44 and 45, respectively, and can communicate with the controller 230. The solar radiation sensor 14 is installed, for example, in the cultivation space 10a, detects the intensity of sunlight in the cultivation space 10a, and measures the amount of solar radiation. The amount of solar radiation is the amount of radiant energy that a unit area receives from the sun in a unit time. In addition, the above-mentioned moisture soil sensor 15 is inserted into the soil in the agricultural house 10, for example, and measures the soil moisture content of the soil. The soil water content is the proportion of soil water in a unit volume. The solar radiation sensor 14 and the water/soil sensor 15 may not be connected to the communication cable 44 or the like. When the sensor is not connected to the communication cable 44 or the like, communication from the sensor to the controller 230 may be performed using various wireless technologies such as Bluetooth (registered trademark), Wi-Fi, or public wireless communication.

Like the controller 30, the controller 230 has a contact output unit 31, an instruction unit 32, an input unit 33, a processing unit 34, a transmission unit 35, and a storage unit 36. Measured values are input to the input unit 33 of the controller 230 from the solar radiation sensor 14 and the moisture soil sensor 15, respectively. Here, the cultivation space environment information SI includes, in addition to the measured values of the temperature sensor 11, the humidity sensor 12, and the carbon dioxide sensor 13, the measured values of the solar radiation sensor 14 and the moisture soil sensor 15.

The processing unit 34 of the controller 230 determines the contact output (either “ON” or “OFF”) of the contact output unit 31 according to the condition of the control condition information CO based on the above-mentioned cultivation space environment information SI.

The control condition that is the control condition information CO and that turns on (or turns off) the function of each environment adjustment device 20 is one of the six conditions of temperature, humidity, carbon dioxide concentration, satiation, solar radiation, and soil moisture. It may be set based on any one of the six measured values, may be set based on any of the two to five measured values of these six, or may be set based on all the six measured values. May be.

When the environment adjustment device 20 includes a irrigation device, that is, when the irrigation device is connected to one of the terminals 30a of the controller 230, the control condition information CO is, for example, when the amount of solar radiation is a predetermined amount or more. The conditions include turning on the function of the irrigation device, and turning off the function of the irrigation device when the soil water content is a predetermined amount or more.

According to the environment adjustment system including the controller 230 according to such a modification, in addition to the effects of the environment adjustment system 100 described above, the environment of the cultivation space 10a can be controlled based on the amount of solar radiation and the amount of soil water. Therefore, the environment of the cultivation space 10a can be adjusted more finely.

The controller 230 according to the modification described above is connected to both the solar radiation sensor 14 and the moisture soil sensor 15 in addition to the three types of sensors including the temperature sensor 11, the humidity sensor 12, and the carbon dioxide sensor 13. Although it is a configuration, instead of this, a configuration in which a total of four types of sensors in which only one of the solar radiation sensor 14 or the moisture soil sensor 15 is added in addition to the above three types of sensors may be connected may be used.

The embodiments have been described above, but the present invention is not limited to the above description, and various modifications can be made without departing from the scope of the present invention.

For example, in the environment adjustment system 100 of the above-described embodiment, the agricultural house 10, the controller 30, and the mobile terminal 40 are provided one by one, but the invention is not limited to this, and the agricultural house 10, the controller 30, and the portable house 40 are provided. A configuration including one or more mobile terminals 40 may be used.

Further, in the environment adjustment system 100 of the above-described embodiment, the number of terminals 30a and the like provided in the controller 30 is four, but the number is not limited to this, and the number of terminals 30a and the like provided in the controller 30 is 1 to The number may be three, or may be five or more.

By the way, in the environment adjustment system 100 described above, a single board computer equipped with a relatively inexpensive microcomputer is assumed as a computer constituting the instruction unit 32, the input unit 33, and the processing unit 34 in the controller 30. Therefore, in view of the data processing capability of a general microcomputer at the time of filing the present invention, it is preferable that the number of terminals 30a and the like included in one controller 30 be set within four. However, depending on various circumstances such as improvement of the processing capacity of the computer and cost reduction of the computer in the future, it is possible to set the number of terminals 30a etc. included in one controller 30 to 5, and of course 6 or more. It is also possible.

Further, the environment adjustment system 100 of the above-described embodiment has a configuration including one controller 30 and four environment adjustment devices 20, but is not limited to this, and, for example, five or more environment adjustment devices 20 and A plurality of controllers 30 for controlling these environment adjusting devices 20 may be provided. Further, in the environment adjusting system 100, the number of the environment adjusting devices 20 connected to one controller 30 via the cable is four, but it may be one to three or five or more. When five or more environment adjusting devices 20 are connected to one controller 30 via a cable, the controller 30 is provided with five or more terminals 30a or the like corresponding thereto.

Also, the environment adjustment system 100 may include five or more environment adjustment devices 20 and a plurality of controllers 30 that control these environment adjustment devices 20. That is, when it is desired to use five or more environment adjusting devices 20, the number of terminals 30a of the controller 30 will be insufficient, but it is possible to cope with this by using a plurality of controllers 30. Further, the environment adjustment system 100 may include a plurality of mobile terminals 40. When a plurality of users use the environment adjustment system 100, it is possible for each of the plurality of users to carry the mobile terminal 40.
