(Temperature conditions for plant seedlings)
There are two methods to make plants: (1) direct seeding cultivation in seeds and so on, and (2) seeding seedlings in seedlings, raising seedlings (nurturing seedlings) and then transplanting them in the fields. is there. For example, (1) the objects of direct sowing cultivation include spinach such as leaf vegetables, daikon, hakusasai, shungyoku, lettuce and the like. On the other hand, (2) the targets for transplantation cultivation include fruit vegetables such as tomatoes, eggplants, peppers, cucumbers, watermelons, and melons.

For example, as shown in FIG. 4 (a), the temperature range of seedling conditions for fruit vegetables such as tomatoes, eggplants, peppers, cucumbers, watermelons and melons is 24 degrees to 30 degrees in the daytime and 15 degrees to 22 degrees in the nighttime. There is a range. And as an appropriate temperature common to each plant, 25 degree | times-27 degree | times become an appropriate temperature when growing these plants about daytime. However, the optimal temperature common to each plant is as follows: (1) Tomato and cucumber at 17 degrees, (2) Eggplant, pepper, cucumber, watermelon and melon at 18 to 20 degrees. The optimum temperature is slightly different.
However, when raising the above-mentioned two groups, it seems that raising the room temperature in the range of 17 to 18 degrees does not affect the raising of the seedlings.

(Temperature conditions for plant growth)
And as shown in FIG.4 (b), as temperature ranges of the growth conditions of fruit vegetables, such as a tomato, an eggplant, a bell pepper, a cucumber, watermelon, a melon, and a pumpkin, it is 18-30 degree in the daytime, and 8 degree-20 in the nighttime. There is a range of degrees. And as an appropriate temperature common to each plant, about 23 degree | times becomes an appropriate temperature when growing these plants about daytime. However, as the optimum temperature common to each plant, at night, (1) tomato and pumpkin are 10 degrees, (2) eggplant, cucumber, watermelon and pumpkin are 13 to 15 degrees, (3) peppers, watermelon and melon The optimum temperature is 18 degrees, and the optimum temperature is different for each group. The growth conditions for leafy vegetables such as spinach, Japanese radish, scallops, celery, honey bees, pungyaku, lettuce, etc. are optimal temperatures of 15 to 20 degrees in the daytime as an appropriate temperature common to each plant.
Here, in the daytime, there is a temperature difference of “minimum 3 degrees” with 23 degrees of fruit vegetables and 20 degrees of leaf vegetables as the optimum temperature, and “maximum 8 degrees” with 23 degrees of fruit vegetables and 15 degrees of leaf vegetables as the optimum temperatures. is necessary.
Next, leafy vegetables can be grown with a long day length, and the sunshine time affects growth compared to fruit vegetables. Here, the minimum limit temperature common to leaf vegetables is 5 degrees, and the maximum limit temperature is 23 degrees. The optimum temperature at night is (1) 10 degrees for tomatoes and pumpkins, (2) 15 degrees for eggplant and cucumbers, and (3) 18 degrees for peppers, watermelons and melons. Therefore, it is possible to grow fruit vegetables and leaf vegetables at the same time by controlling the temperature at night with the appropriate temperature of fruit vegetables, irradiating the leaf vegetables with LED 61, and preventing the fruit vegetables from being exposed to light by the partition 63a. It becomes.
Therefore, in the plant growth space control system 100 according to the present invention, in the daytime, the plant cultivation room 210 shades the partition 63a and the like to create the temperature difference and bring it close to the appropriate temperature for each group. Plants can be grown in the plant cultivation room 210 at the same time, and at night, seedlings can be brought close to the optimum temperature by illuminating only leaf vegetables with the LED 61.
In addition, about strawberry, since the low temperature is required compared with other plants at 5 to 8 degrees at night, it is desirable to grow alone.

(Illumination conditions for plant growth)
Generally, 20-30 klx (kilolux) is necessary as the illuminance condition for growing leafy vegetables, and 70-80 klx (kilolux) is necessary as the illuminance condition for growing fruit vegetables. And leafy vegetables can grow for a long day length, and fruit vegetables need 6-8 hours at night. Therefore, when leaf vegetables and fruit vegetables are grown in the same place, it is necessary to place the fruit vegetables in a place that is exposed to natural light from the outdoors during the day and in a place where the light from the LED 61 is not exposed at night. is there.

(Configuration according to the present invention)
Hereinafter, the configuration according to the present invention among the configurations described above and the operational effects obtained from this configuration will be described.

  As shown in FIGS. 1 and 2, the plant growth space control system 100 includes detection means 20, 30, and 40 that measure the environment inside and outside a building 200, and the detection results of the detection means 20, 30, and 40. The air conditioner 50 installed in the building 200 and the control means 11 for controlling the equipment 60 installed in the building 200 or outdoors. And the plant cultivation room 210 which grows the plant in which the said air conditioner 50 was installed is provided in the said building 200. FIG. The detection means 30 measures the environment in the plant cultivation room 210, and the control means 11 is optimal for the growth of plants in the plant cultivation room 210 according to the detection result in the plant cultivation room 210 by the detection means 30. The facility device 60 is controlled so as to take in a new environment from the environment inside or outside the building 200 in preference to the air conditioner 50.

For example, it is assumed that tomatoes of fruit vegetables and spinach of leaf vegetables are grown in the plant cultivation room 210. As shown in FIG. 5 and FIG. 6, the control means 11 periodically acquires the optimum environmental information of the plant from the external server 80, and the environmental information of the outdoor and indoor plant cultivation rooms 210 and rooms 220, 230, and 240. Is acquired (step S1). Here, the control part 11 acquired from the external server 80 (1) The optimal room temperature of a tomato is 20 to 25 degree | times, optimal humidity is 50 to 70%, optimal illumination intensity is 70 to 80 klx, (2) Spinach The storage unit 13 stores that the optimum room temperature is 15 degrees to 20 degrees, the optimum humidity is 70 to 80%, and the optimum illumination intensity is 20 to 30 klx.
Next, the indoor environment measured by the indoor sensors 30 and 40 is compared with the outdoor environment measured by the outdoor sensor 20 (step S2). In the example shown in FIG. 5, the optimum temperature common to tomatoes and spinach is 20 degrees. On the other hand, the room temperature of the plant cultivation room 210 is 15 degrees. Since the outdoor temperature (outside temperature) is 23 degrees and the outside temperature is close to the common optimum temperature of 20 degrees for tomato and spinach, the opening is opened (steps S3 and S4). That is, the control means 11 controls the opening / closing means 66 to open the window 210a. In addition, when the electric shutter 62a is not opened, the control unit 11 drives and controls a drive unit (not shown) of the electric shutter 62a so as to open the electric shutter 62a. Thereby, outside air can be taken in into the plant cultivation room 210, and the room temperature of the plant cultivation room 210 can be brought close automatically to an appropriate temperature of 20 degrees. In addition, when the room 220 and the outdoor air temperature are not within the appropriate temperature range, the air conditioner 50 is operated to approach the appropriate temperature (step S5).

  According to this configuration, the control unit 11 prioritizes the environment optimal for the growth of the plants in the plant cultivation room 210 over the air conditioner 50 according to the detection result in the plant cultivation room 210 by the detection unit 30. And since the said equipment 60 is controlled to take in from the said building 200 or an outdoor environment, it becomes possible to take in from the said building 200 or an outdoor environment, suppressing the said air conditioner 50 to the minimum. Therefore, the environment of the plant growing space can be automatically brought close to the optimum growing environment while saving energy.

  Here, it is assumed that the air conditioner 50 is a device that continuously uses power, and the facility device 60 is devices 62 and 66 that temporarily use power. For example, in the above example, the electric shutter 62a and the opening / closing means 66 correspond to the equipment 60 that temporarily uses power.

According to this configuration, the air conditioner 50 is a device that continuously uses electric power, and the facility device 60 is the devices 62 and 66 that temporarily use electric power, giving priority to the air conditioner 50. By using the equipment 60, it is possible to reduce the power consumption when the environment of the plant growing space is automatically brought close to the optimum growing environment, and therefore CO ₂ emission can be reduced.

  Next, for example, as shown in FIGS. 1, 2, and 6, the building 200 is provided with a solar power generation device 64 and a storage battery 65 capable of storing direct current output from the solar power generation device 64, When the LED 61 is installed in the plant cultivation room 210 and the control unit 11 determines that the illuminance of outdoor lighting measured by the detection unit 20 in the plant cultivation room 210 is insufficient. Then, power is supplied from the storage battery 65 to the LED 61, and the LED 61 is turned on (steps S6 and S7). In the example shown in FIG. 5, since the illuminance of the outdoor environment is 50 klx, which is less than the optimum illuminance of tomatoes 70 klx, the control means 11 includes the storage battery 65 so that the LED 61 is turned on and the optimum illuminance of tomatoes is 70 to 80 klx. Is controlled so that the illuminance of the LED 61 becomes the optimum illuminance of 70 to 80 klx.

According to this configuration, the building 200 is provided with the solar power generation device 64 and the storage battery 65 capable of storing the direct current output from the solar power generation device 64, and the plant cultivation room 210 is provided with the LED 61. When the control unit 11 determines that the illuminance of outdoor daylighting measured by the detection unit 20 in the plant cultivation room 210 is insufficient, the control unit 11 supplies power to the LED 61 from the storage battery 65. By turning on the LED 61, for example, it is possible to supply direct current output from the solar power generation device 64 to the storage battery 65 in the daytime, charge the storage battery 65, and supply power from the storage battery 65 to the LED 61 at night or the like. , CO ₂ emissions can be reduced, and the illuminance necessary for growth of a spot can be maintained.

Next, for example, as shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 6, the equipment 60 is shielding means 62 a provided on the outdoor side of the plant cultivation room 210. Is provided with a planter 70 classified according to the type of plant and a moving means 63 for moving the planter 70 as the equipment 60, and the planter 70 is used for photosynthesis of the plant (leaf vegetables, fruit vegetables). Detection means 71 for detecting the speed is installed, and the control means 11 is automatically operated by the moving means 63 according to the photosynthesis speed of the plant (leafy vegetables, fruit vegetables, etc.) detected by the detection means 71. The location of the planter 70 is moved or the opening / closing of the shielding means 62 is controlled. Here, the plurality of planters 70 are divided by the shelves 73 or the partitions 63a and 63b for each kind of plant (for example, fruit vegetables and leaf vegetables). For example, as shown in FIG. 3, the shelf 73 can place a plurality of planters 70 and is placed on the moving means 63, and as shown in FIG. 2, the partition 63 a is arranged on the moving means 63 in the circumferential direction. Planters 70 are installed at predetermined intervals, and planters 70 in which plants of the same type or similar types are planted between partitions 63a, 63a adjacent in the circumferential direction. Moreover, the partition 63b has what is arrange | positioned on the floor of the center part of the moving means 63, and is installed in the intermediate position of the window 210a and the window 220a in parallel with the said window 210a, 220a. The shelf 73 is used when many planters 70 are to be placed on the moving means 63. In addition, the partitions 63a and 63b are used, for example, to divide fruit vegetables that require sufficient light from leaf vegetables that require light that is weaker than fruit vegetables and adjust light.
The unit of the rate of photosynthesis can be expressed by, for example, the amount of oxygen generated / time. Here, as shown in FIG. 3C, a detection means 73 for measuring the rate of photosynthesis is attached to each planter 70 (leaf vegetable spinach, fruit vegetable tomato). In this case, the detection unit 73 transmits information on the speed of photosynthesis to the control unit 11 by wireless. For example, in tomato and spinach, as shown in FIG. 5, the tomato has a higher optimum illuminance than spinach, so that the photosynthesis detected by the detection means 73 installed in the tomato planter 70 is low. The control means 11 controls the movement means 63 to rotate or opens the shielding means 62a so as to approach either the window 210a or the window 210b. Since the speed of photosynthesis is proportional to the illuminance, the measurement data is stored in the storage means 13 in advance. Then, the control unit 11 compares the detection result detected by the detection unit 71 with the photosynthesis speed stored in the storage unit 13, and drives the moving unit 63 to rotate when the photosynthesis rate is low. For example, when the photosynthetic speed is lowered due to the movement of the sun, the moving means 63 is rotated counterclockwise.

According to this configuration, the control unit 11 automatically moves the place of the planter 70 by the moving unit 63 according to the photosynthesis speed of the plant (leafy vegetables, fruit vegetables, etc.) detected by the detecting unit 71. Or, by controlling the opening and closing of the shielding means 62a, for example, when the illuminance of the daylighting from the outdoors is insufficient due to the movement of the sun, the illuminance of Since the shortage can be eliminated, the illuminance necessary for the growth of the spot can be maintained.
Moreover, since the several planter 70 is divided by the kind with the partitions 63a and 63b, sunlight or the light of LED61 can be applied to the desired planter 70, ie, the desired kind of plant.

  Next, for example, as shown in FIG. 1, FIG. 2, and FIG. 6, the light from the plant cultivation room 210 provided between the plant cultivation room 210 and the room 220 adjacent to the plant cultivation room 210 is illuminated. When the detection means 40 detects whether a person is staying in the room 220 adjacent to the plant cultivation room 210, and the control means 11 detects that a person is staying. The shielding means 62b is controlled so that light does not leak from the plant cultivation room 210 into the room 220 where the person stays. For example, when the LED 61 is lit at night, the control means 11 detects that a person is staying in the room 220 by the human sensor 44 and at a predetermined time (for example, 10:00 at night). Then, the shielding means 62b is closed so that the light in the plant cultivation room 210 does not leak into the room 220 (steps S8 and S9).

  According to this configuration, when the control means 11 detects that a person is staying, the light from the plant cultivation room 210 is prevented from leaking from the plant cultivation room 210 into the room 220 where the person stays. By controlling the shielding means 62b that can be shut off, light does not leak from the plant cultivation room 210 to the adjacent room 220. For example, when the LED 61 is lit at night, a predetermined time (for example, night 10). ), The shielding means 62b can be controlled so that light does not leak from the plant cultivation room 210 to the adjacent room 220, and the LED 61 is affected by lighting the person staying in the adjacent room 220. Can be prevented.

Next, for example, as shown in FIGS. 1 and 2, it further includes an opening / closing means 66 for controlling the opening / closing of a window 220a provided between the plant cultivation room 210 and the room 220 adjacent to the plant cultivation room 210, The detection means 40 measures the concentration of CO _{2 in} the room 220, and the control means 11 controls the opening / closing means 66 to open the window 220a when the CO ₂ concentration is a certain value or more. Here, the window 220a is assumed to be an exit window. On the other hand, the concentration of CO ₂ in said plant cultivation room 210 decreases by photosynthesis of plants, the concentration of CO ₂ in the next room 220 because human is relatively high and is staying, the CO ₂ is the It flows into the plant cultivation room 210. For example, in the daytime when tomatoes and spinach are photosynthesising, if the concentration of CO _{2 in} the room 220 is a certain value (for example, 1000 ppm) or more, by opening the window 220a by driving the opening and closing means 66, Air containing CO ₂ in the room 220 can be caused to flow into the plant cultivation room 210.

According to this configuration, the control means 11 controls the opening / closing means 66 so that the air in the room 220 flows into the plant cultivation room 210 when the concentration of CO ₂ is a certain value or more, so that the plant is Since O ₂ can be generated from CO ₂ by photosynthesis, the amount of CO ₂ emission can be reduced, and the environment necessary for the growth of a spot can be maintained.
