Further, this cultivation container 12 may be installed either outdoors, such as on a balcony or balcony, or indoors, such as a living room or living room, or may be installed in any of a commercial facility, a single-family house, a housing complex, etc.

The installation environment information acquisition unit 14 is for acquiring installation environment information that is information about the environment in which the cultivation container 12 is installed. The environment in which the cultivation container 12 is installed is the environment outside the cultivation container 12 (soil container 22 and upper cover 24), and if the cultivation container 12 is installed in a building, the environment inside the building. If the cultivation container 12 is installed outside a building, it is the environment around the cultivation container 12 outside the building. The environment in which the cultivation container 12 is installed influences the growth of the plants P. Further, the information on the environment in which the cultivation container 12 is installed includes, for example, the atmospheric pressure, temperature, humidity, illuminance, amount of solar radiation, wind speed, weather conditions, etc. of the environment in which the cultivation container 12 is installed.

This installation environment information acquisition unit 14 includes a barometer 30 that detects the atmospheric pressure of the environment in which the cultivation container 12 is installed, and a thermometer 32 and a hygrometer 33 that respectively detect the temperature and humidity of the environment in which the cultivation container 12 is installed. , an anemometer 34 that detects the wind speed in the environment in which the cultivation container 12 is installed, an illumination meter 35 and a solar radiation meter 37 that measure illuminance and solar radiation, respectively, and meteorological data in the environment in which the cultivation container 12 is installed. It has a weather data receiving section 36 for receiving weather data. Weather data is created by weather forecast-related organizations and companies, and is transmitted from data transmission bases. This installation environment information acquisition unit 14 is arranged outside the cultivation container 12. This installation environment information acquisition unit 14 may be provided integrally with the cultivation container 12, or may be placed apart from the cultivation container 12.

The soil environment information acquisition unit 16 is for acquiring soil environment information that is information about the environment inside the soil 26. The information on the environment in the soil 26 is, for example, the temperature and moisture content in the soil 26. The soil environment information acquisition unit 16 includes a thermometer 38 that detects the temperature of the environment inside the soil 26, and a soil moisture meter 40 that detects the moisture content of the environment inside the soil 26. This sub-soil environment information acquisition unit 16 is placed in the soil 26.

The cultivation environment adjustment section 18 is for adjusting the cultivation environment of the plants P. The cultivation environment includes, for example, the intensity of the light irradiated to the plant P, the light quality (spectral distribution of light), the irradiation time, the temperature and humidity around the trunk and leaves of the plant P, and the wind provided to the plant P. strength, the amount of water provided to the plant P, and the temperature and humidity of the soil 26. This cultivation environment adjustment unit 18 includes a light source 42 that irradiates light to the plants P, a ventilation fan 44 that adjusts ventilation and flow of air, temperature and humidity inside the upper cover 24, and a mist generator that provides mist to the plants P. It has a device 46, a blower device 48 that blows air to the plants P, an irrigation device 50 that waters the plants P, and a temperature adjustment device 52 that adjusts the temperature of the soil 26.

The light source 42 is provided, for example, on the upper part of the upper cover 24, and the temperature adjustment device 52 is placed in the soil 26. The temperature control device 52 has, for example, a heating function that heats the soil 26 and a cooling function that cools the soil 26. For example, a heater is used for the heating function, and for example, a water-cooled heat exchanger, a Peltier element, or the like is used for the cooling function. The ventilation fan 44, the mist generator 46, the blower 48, and the irrigation device 50 are fixed to the upper cover 24 as appropriate.

The control device 20 is for controlling the cultivation environment adjustment section 18 based on the installation environment information and the soil environment information so that the cultivation environment of the plant P matches the cultivation conditions suitable for the plant P. The control device 20 includes a CPU (Central Processing Unit) 54, a ROM (Read Only Memory) 56, a RAM (Random Access Memory) 58, a nonvolatile memory 60, and an information display means 64. The CPU 54 is an example of a "control unit", and the nonvolatile memory 60 is an example of a "cultivation condition storage unit". Further, the information display means 64 is a device that displays text information and images, such as a liquid crystal display.

A program 62 is stored in the ROM 56, and the CPU 54 either reads and executes the program 62, or expands the program 62 into the RAM 58 and executes it.

The nonvolatile memory 60 stores cultivation conditions suitable for the plant P. The cultivation conditions correspond to growth conditions and growth factors that allow the plant P to grow appropriately, and weather conditions suitable for the plant P. These cultivation conditions include, for example, the intensity and quality of the light irradiated to the plant P, the light quality (spectral distribution of light), the temperature and humidity around the trunk and leaves of the plant P, and the strength of the wind provided to the plant P. , the amount of water provided to the plants P, and the appropriate amounts of the temperature and humidity of the soil 26. The nonvolatile memory 60 stores cultivation conditions for each type of plant P. These cultivation conditions may be set separately for each day and time of the year, for each month and day of the year, or for each season of the year.

Here, as shown in the block diagram of FIG. 2, the nonvolatile memory 60 serving as a cultivation condition storage section is provided with a plant species data storage section 60a in which data regarding plants to be cultivated is stored. The "cultivation conditions suitable for plants" in this plant species data will be explained. "Cultivation conditions suitable for a plant" used in this embodiment refers to the growing conditions, cultivation conditions, and excess/deficiency conditions necessary for the plant to grow appropriately based on data regarding the plant by measuring the outside air environment and soil environment. It was extracted by repeatedly performing verifications under different growth conditions and excess/deficiency conditions, and was not determined simply by using conventional plant data. In other words, "cultivation conditions suitable for a plant" used in this embodiment include "distribution area of the plant's original roots," "each root and region of origin of the plant that was multiplied in the process of creating the plant," and "region of origin." We repeatedly verify the growing conditions, cultivation conditions, and surplus/deficiency conditions necessary for proper growth, while considering the variety characteristics and cultivation conditions, etc., while varying the growth conditions and surplus/deficiency conditions. , the growth conditions and elements necessary for growth have been reorganized and extracted to fit the plant classification.

Among the plant species data, data related to sunlight, irradiation time, and soil moisture content (pF value) indicating the wet and dry state of the soil are expressed, for example, as shown in Table 1 below.

"Numerical data" in Table 1 above represents boundary values of illumination intensity, irradiation time, and soil moisture content. For example, the numerical data "0" corresponds to an illuminance of 300 lux and an irradiation time of 3 hours, the numerical data "30" corresponds to an illuminance of 600 lux and an irradiation time of 4 hours, and the numerical data "60" corresponds to an illuminance of 1200 lux and an irradiation time of 4.8 Corresponding to time, the numerical data "104" corresponds to an illuminance of 2000 lux and an irradiation time of 6 hours, and the numerical data "155" corresponds to an illuminance of 2500 lux and an irradiation time of 12 hours. Then, the illuminance and irradiation time corresponding to the numerical data between the boundary values are proportionally divided in the range between the boundary values. For example, the numerical data "15" corresponds to exactly half of the numerical data "0" and "30", so it corresponds to an illuminance of 450 lux, which is the median value between the illuminance of 300 lux and 600 lux, and similarly the irradiation time is 3. Corresponds to .5 hours.

In addition, regarding the dry and wet conditions of the soil shown in Table 1 above, the numerical data "0" to "60" indicate the moist state, the numerical data "60" to "104" indicate the appropriate humidity state, and the numerical data "104" to "155" indicate the moist state. ” indicates the dry state. Specifically, a wet state shows a pF value of 1.5 to 1.8, a proper humidity state shows a pF value of 1.8 to 2.7, and a dry state shows a pF value of 2.7 to 3.6. The specific soil moisture content (pF value) corresponding to the specific numerical data is proportionally divided in the range between the boundary values, as in the case of the above-mentioned illumination intensity and irradiation time.

A specific example of plant species data is shown in the schematic diagram of FIG. For each plant species (A to V), the applicable ranges of illuminance, irradiation time, and dry/wet conditions are numerical ranges indicated by arrows. For example, plant species A has been shown to prefer low light intensity, short exposure time, and moist conditions, and plant species V has been shown to prefer high light intensity, long exposure time, and dry conditions.

The specific numerical range for each plant species is as shown in Table 2 below.

Here, the lower limit value is the leftmost value of the numerical range shown in FIG. 3, and the upper limit value is the rightmost value. Also, the median reference value is the median between the lower limit and the upper limit, the lower reference value is the median between the lower limit and the median reference value, and the upper reference value is the median between the middle reference value and the upper limit. is the median value between. In other words, among the values that divide the numerical range into four equal parts, the smallest value is the lower reference value, the middle value is the central reference value, and the largest value is the upper reference value. For example, for plant species E, the median reference value is shown by the broken line in FIG. 3, and the lower reference value and the upper reference value are shown by the dashed-dotted line.

Next, the operation of the plant cultivation device 10 according to this embodiment will be explained.

When the plant cultivation apparatus 10 is powered on, the CPU 54 sequentially executes steps S1 to S5 shown in the flowchart of FIG.

In step S1, the CPU 54 acquires the installation environment information acquired by the installation environment information acquisition section 14. This installation environment information includes output data from the barometer 30, thermometer 32, hygrometer, illumination meter, solar radiation meter, anemometer 34, and weather data receiving unit 36, that is, the environment in which the cultivation container 12 is installed. It includes data on barometric pressure, sunlight, temperature, wind speed, and weather conditions. Note that in step S1, humidity may be predicted from the atmospheric pressure and temperature, and this predicted humidity data may be used later.

In step S2, the CPU 54 acquires the soil environment information acquired by the soil environment information acquisition section 16. This soil environment information includes output data from the thermometer 38 and soil moisture meter 40, that is, data corresponding to the temperature and dry/wet state of the environment within the soil 26.

In step S3, the CPU 54 extracts cultivation conditions suitable for the plant P arbitrarily selected by the user based on the plant data collected and stored in the nonvolatile memory 60. These cultivation conditions include, for example, the intensity of the light irradiated to the plant P, the quality of the light (spectral distribution of light), the irradiation time, the temperature and humidity around the trunk and leaves of the plant P, and the amount of light provided to the plant P. This includes the appropriate amount of wind strength, the amount of water provided to the plants P, and the temperature and humidity of the soil 26. At this time, if the cultivation conditions are set separately for each hour of each day of the year, for each month and day of the year, or for each season of the year, the timing at which step S3 is executed (the cultivation conditions are extracted The cultivation conditions corresponding to the timing of the cultivation are extracted. Moreover, cultivation conditions are extracted for each variety of plant P. Note that the order of steps S1 to S3 described above may be other than the above.

Here, a specific example will be explained. For example, if the plant P is sensitive to heat and the temperature of the environment in which the cultivation container 12 is installed exceeds 30° C., the growth of the plant P may decline. In this case, the ventilation fan 44, the mist generator 46, the air blower 48, and the temperature adjustment device 52 are controlled so that the temperature is suitable for cultivating the plants P, and the environment for cultivating the plants P is appropriately adjusted.

In step S4, the CPU 54 controls the cultivation environment adjustment unit 18 based on the installation environment information and soil environment information acquired in steps S1 and S2 so that the cultivation environment of the plant P matches the cultivation conditions extracted in step S3. Calculate the control value of. This control value includes control values for the light source 42, ventilation fan 44, mist generator 46, blower 48, irrigation device 50, and temperature adjustment device 52.

In step S5, the CPU 54 controls the light source 42, ventilation fan 44, mist generator 46, air blower 48, irrigation device 50, and temperature adjustment device 52 using the control values calculated in step S4. As a result, the cultivation environment adjustment unit 18 (light source 42, ventilation fan 44, mist generation device 46, ventilation device 48, irrigation device 50, and temperature adjustment device 52) is controlled so that the cultivation environment of the plant P matches the cultivation conditions, The cultivation environment of the plant P is appropriately adjusted. The CPU 54 repeatedly executes steps S1 to S5 until the power to the plant cultivation device 10 is stopped.

In addition, the light source 42, The ventilation fan 44, the mist generator 46, the blower 48, the irrigation device 50, and the temperature controller 52 are controlled, and the cultivation environment for the plants P is appropriately adjusted. That is, the installation environment information acquisition unit 14 reads the current state of the environment in which the plant P is placed, and the control device 20 predicts changes in the current state (changes in weather) and appropriately (early) determines the optimal growth environment for the plant P. The cultivation environment adjustment section 18 and the temperature adjustment device 52 provide the necessary elements for the cultivation container 12 and the soil 26. Moreover, in this case, humidity may be predicted from the atmospheric pressure and temperature, and the control device 20 may predict changes in the current state of the environment in which the plants P are placed (changes in weather) using the predicted humidity data. . Furthermore, the control device 20 may grasp changes in the current state of the environment where the plants P are placed (changes in the weather) based on data obtained from the weather data receiving unit 36 (weather change prediction data). The optimum growth environment for the plant P may be provided by the cultivation environment adjustment section 18 and the temperature adjustment device 52 before stress is applied to the plant P.

In addition, for example, when the night temperature is high, such as on a tropical night, the exhaustion of the plant P due to respiration increases, and the growth, flower buds, fruit set, etc. of the plant P become worse. The ventilation fan 44, the mist generator 46, the blower 48, and the temperature controller 52 are controlled so that the temperature is maintained, and the cultivation environment for the plants P is appropriately adjusted.

In addition, if the lack of sunlight continues, the light source 42 is controlled to ensure the sunshine hours, amount of sunlight, and light quality (spectral distribution of light) suitable for cultivating the plants P, and the cultivation environment of the plants P is changed. properly adjusted.

Hereinafter, the operation of the plant cultivation apparatus 10 according to the present embodiment will be described with respect to control of illumination intensity, irradiation time, and soil moisture content.

FIG. 5 is a block diagram showing means by which the CPU 54 as a control unit is involved in controlling illuminance and irradiation time. Each means in FIG. 5 is realized by the CPU 54 executing a predetermined portion of the program 62. Each means in FIG. 5 will be explained with reference to the flowchart in FIG. 6.

In step S10, the first display means 54a displays the names of a plurality of plant species (for example, plant species A to V in FIG. 3 and Table 2) from the plant species data storage section 60a (see FIG. 2) using the information display means. 64.

In step S11, the first selection means 54b allows the user to select a specific name from among the plurality of plant species displayed on the information display means 64, and selects the plant species related to the specific name selected by the user as a specific plant. Determine as a species. Below, the case where plant species E is selected will be explained as an example.

In step S12, the reference value acquisition means 54c acquires the central reference value, lower reference value, and upper reference value for the specific plant species. For example, in the case of plant species E, the numerical data indicated by the broken line in Figure 3 is the central reference value, and of the two numerical data indicated by the two dot-dashed lines, the left one is the lower reference value, and the right one is the upper reference value. It is a value.

In step S13, the second display means 54d selects plant species that include the lower reference value in the numerical range from the plant species data storage unit 60a (see FIG. 2) as a first group, and selects plant species that include the lower reference value in the numerical range. Plant species are selected as the second group, plant species that include the upper reference value within the numerical range are selected as the third group, and the names of each group are displayed on the information display means 64.

For example, in the example shown in FIG. 3, in addition to plant species E, which is a specific plant species, plant species A, B, C, D, F, G, and H are selected as the first group, and the information display means 64 Is displayed. Further, as a second group, in addition to plant species E, which is a specific plant species, plant species A, B, C, D, F, G, and H are selected and displayed on the information display means 64. Further, as a third group, in addition to plant species E, which is a specific plant species, plant species D, F, G, H, I, J, K, L, M, and N are selected and displayed on the information display means 64. be done.

Here, the first group is selected as plant species that are suitable for humid conditions within the numerical range of the specific plant species. Furthermore, the second group is selected as plant species that are suitable for optimal dry and wet conditions within the numerical range of the specific plant species. Furthermore, the third group is selected from the numerical range of the specific plant species as plant species that are suitable for dry conditions.

In step S14, the second selection means 54e allows the user to select a specific group from among the first group, second group, and third group displayed on the information display means 64, and specifies the group selected by the user. Decide as a group.

Then, in step S15, after the user plants some or all of the plant species of the specific group as plants P in the cultivation container 12, in step S16, the cultivation environment adjustment unit 18 sets the reference value related to the specific group, i.e. , set the illumination intensity and irradiation time corresponding to either the lower reference value, the central reference value, or the upper reference value, and use the set illuminance and irradiation time to apply to a specific group of plants cultivated in the cultivation container 12. , a light source 42 is used to irradiate the light beam. Note that the plants P actually planted by the user may be one type or a plurality of types among the plant species of the specific group, and the specific plant species may not necessarily be included therein. By doing so, it becomes possible to select a plant species other than the one that the user had expected, and there is an advantage that the selection of plant species is expanded.

Various modes of irradiation with this light beam are possible. For example, a light beam may be irradiated with a constant illuminance during a set irradiation time. Alternatively, the illuminance may be gradually increased to a set illuminance from the start of irradiation until the middle of the set irradiation time, and after reaching the set illuminance, the illuminance may be gradually decreased until the end of the irradiation time. Note that the manner in which the illuminance gradually increases and decreases may be linear according to a linear function, or may be approximated to a curved function (for example, a parabola, a normal distribution curve, a sigmoid curve). Good too.

Regarding the setting and control of the dry and wet state of the soil, in step S16, the cultivation environment adjustment unit 18 sets the standard value corresponding to the specific group, that is, the lower standard value, the central standard value, or the upper standard value. A specific group of plants cultivated in the cultivation container 12 is controlled using the watering device 50, the temperature control device 52, and the blower device 48 so that the soil moisture percentage reaches the set soil moisture percentage. Control takes place.

Next, the functions and effects of this embodiment will be explained.

As described in detail above, according to the present embodiment, even if the environment in which the cultivation container 12 for cultivating the plants P is installed changes, or even if the environment is difficult for the plants P to grow, the plants P The cultivation environment adjustment unit 18 (light source 42, ventilation fan 44, mist generation device 46, ventilation device 48, irrigation device 50, and temperature adjustment device 52) is controlled so that the cultivation environment of the plant P matches the cultivation conditions suitable for the plant P. . As a result, for example, if the environment in which the cultivation container 12 is installed changes due to abnormal weather, is not suitable for the original cultivation of the plant P, or exceeds the northern growth limit of the plant P, the southern growth limit of the plant P can be changed. Even if it is below, the plants P can be appropriately cultivated in consideration of changes in the environment in which the cultivation container 12 is installed.

Further, according to the present embodiment, in addition to installation environment information that is information about the environment in which the cultivation container 12 is installed, soil environment information that is information about the environment in the soil 26 in which the plant P is planted is acquired. The cultivation environment adjustment section 18 is controlled taking this soil environment information into consideration. Therefore, by considering soil environment information that has a large influence on the growth of the plant P, the plant P can be cultivated more appropriately.

Further, according to the present embodiment, the non-volatile memory 60 stores the cultivation conditions for each day and time of the year, for each month and day of the year, or for each season of the year, and the CPU 54 stores the cultivation conditions Cultivation conditions corresponding to the timing of extracting are extracted from the nonvolatile memory 60. Therefore, the plants P can be appropriately cultivated depending on the time of each day of the year, the month and day of the year, or the seasons of the year.

In particular, regarding the control of illuminance and irradiation time, plant species that can be planted together with the specific plant species selected by the user are selected from a plurality of plant species data stored in the plant species data storage unit 60a, and these plant species are actually planted. With plant species planted in the cultivation container 12, light can be irradiated with illuminance and irradiation time suitable for the plant species.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement various modifications other than the above without departing from the spirit thereof. It is.
