FIG. 1 is a schematic overall configuration diagram of a cultivation facility 1 according to a preferred embodiment of the present invention.

<Overall configuration>
As shown in FIG. 1, the cultivation facility 1 includes a housing H that covers the entire cultivation facility 1, a louver device A serving as an illumination adjustment means, and information regarding the cultivation environment of the plants G within the cultivation facility 1. It includes a measuring device D that measures Dt and a control device C that controls the operation of the louver device A. Here, the housing H of the cultivation facility 1 is a general housing made of a light-transmissive sheet, plate material, etc., and is capable of taking in sunlight L indoors. It is also assumed that the plants G to be cultivated are cultivated in the indoor cultivation area Gr of the cultivation facility 1.

The louver device A is disposed in the upper part of the cultivation facility 1 so as to cover the upper part of the cultivation region Gr, and includes a rotating blade member a1 having a light shielding means and a power generation means. The rotating blade member a1 is driven by a motor M, and has the function of adjusting the illuminance in the cultivation facility 1 by changing the amount of sunlight L blocked (or the shading rate), and the function of generating electricity from the sunlight L. have Details of this louver device A will be described later.

The measuring device D is composed of a plurality of sensors capable of measuring the cultivation environment in the cultivation area Gr where the plants G are cultivated, that is, temperature, humidity, illuminance, carbon dioxide concentration, etc. There are multiple locations. The measuring device D is capable of transmitting information Dt regarding the cultivation environment to a control device C, which will be described later, using wired or wireless communication means.

The control device C includes an information processing means C1 that controls the operation of the louver device A, and a storage device C2 capable of storing various information, and acquires information Dt regarding the cultivation environment from the measurement device D and stores it in the storage device C2. At the same time, the information processing means C1 sends a control signal Cs for controlling the drive of the motor M to the louver device A, thereby controlling the operation of the rotating blade member a1. Details of this control device C will be described later.

<Configuration of the louver device>
As shown in FIG. 1, the louver device A has a plurality of rotating blade members a1 that block sunlight L as light blocking means, and the rotating blade members a1 are arranged in the longitudinal direction of the louver device A. Multiple locations are arranged along the (east-west direction). The plurality of rotating blade members a1 are equipped with an elongated rectangular plate-shaped solar panel P as a power generation means. This solar panel P receives sunlight L and generates electricity, and also has the role of blocking sunlight L for illuminance adjustment.

A plurality of rotary blade members a1 are connected to the drive shaft ax, and when the drive shaft ax is rotated by the drive of the motor M which is controlled by the control device C and is capable of forward and reverse rotation, the rotary blade members a1 are connected to each other according to the rotation direction. The solar panel P is configured to be able to rotate forward and backward around a13.

Further, each of the first rotating blade members a11 is configured to operate in conjunction with the drive of the motor M1, and each of the second rotating blade members a12 is configured to operate in conjunction with the drive of the motor M2. Specifically, when the first motor M1 is driven, the drive shaft ax1 connected to the first motor M1 rotates, thereby causing the plurality of first rotating blade members connected to the drive shaft ax1 to rotate. a11, a11, a11... synchronize and rotate the plurality of solar panels P1, P1, P1.... Further, when the second motor M2 is driven, the drive shaft ax2 connected to the second motor M2 rotates, thereby causing the plurality of second rotating blade members a12, a12 connected to the drive shaft ax2 to rotate. , a12... rotate the plurality of solar panels P2, P2, P2... in synchronization. In this way, the first rotating blade member a11 and the second rotating blade member a12 can each operate independently.

FIG. 2 is a perspective view illustrating the arrangement of the rotating blade members a1.
As shown in FIG. 2, the first rotating blade members a11 and the second rotating blade members a12 are arranged alternately from one end side. Further, the rotating blade members a1 are arranged at intervals such that the ends of adjacent rotating blade members a1 overlap when the solar panel P is in a substantially horizontal position. As a result, when the solar panels P (P1, P2) of the rotating blade member a1 are each placed in a substantially horizontal position, the ends of the rotating blade member a1 overlap, making it possible to block the airflow. As a result, the heat retention function and moisturizing function of the cultivation facility 1 can be improved.

FIG. 3 is a schematic right side view of the rotating blade member a1 of the louver device A.
The rotating blade member a1 is mounted horizontally on a support frame h1, and is mounted on a seat plate a15 that is supported and fixed to a horizontal crosspiece h2 that spans the upper part of the cultivation facility 1. , a pedestal a17 which is rotatably attached to a support a16 around a rotation axis a13 and has a solar panel P assembled on its upper surface; a seal part a18 attached to both ends of the pedestal a17; A storage battery a19 for storing power generation and a rotation mechanism a20 for converting the rotational movement of the drive shaft ax into rotational movement of the solar panel P are provided.

The rotation mechanism a20 has a built-in drive gear a22 that meshes with a worm gear a21 provided on the drive shaft ax, and when the drive shaft ax rotates, this drive gear a22 rotates, and as a result, this drive gear A winding shaft a23 coaxially connected to a22 winds up a winding wire a14 attached to a stand a17, thereby making it possible to rotate the solar panel P. In addition, the arrow in FIG. 3 has shown the movement of each member when rotating the solar panel P in the normal rotation direction (counterclockwise) as an example.

FIGS. 4(a) and 4(b) are explanatory diagrams illustrating the operation of the rotating blade member a1.
With the above configuration, the solar panel P disposed on each rotary blade member a1 is moved toward the front side in the paper as shown in FIG. Rotation angle α (0≦α≦90°) in the forward direction (counterclockwise) when viewed from the (west side), and rotation angle β in the reverse direction (clockwise) as shown in Figure 4(b). It is possible to rotate within a range (rotation angle width) of (0≦β≦90°) and change the elevation angle direction F of the solar panel P from east to west within a range of approximately 180°. . Note that the elevation direction F refers to a direction extending perpendicularly from the light shielding surface of the solar panel P. Note that a control device C, which will be described later, can determine the values of the rotation angles α and β based on the control amount of the motor M.

In addition, with the above configuration, by controlling the rotation of the solar panel P of the rotating blade member a1, the louver device A not only adjusts the illuminance in the cultivation facility 1, but also adjusts the gap between the rotating blade members a1. Through the adjustment, it is possible to adjust the temperature and humidity inside the cultivation facility 1. That is, by widening the gap between the rotating blade members a1 to improve air permeability, it is possible to reduce the temperature and humidity inside the cultivation facility 1, and by narrowing the gap between the rotating blade members a1, the air permeability is reduced. The temperature and humidity inside the cultivation facility 1 can be increased by closing or blocking the airflow.

Further, seal portions a18 having a substantially U-shaped surface cross section are provided at both ends of the pedestal a17 so as to protrude downward. This seal portion a18 is formed of an elastic member such as flexible rubber. As a result, when each solar panel P is rotated into a substantially horizontal position, the seal portion a18 closes the gap that occurs between the ends of the rotary blade members a1 in the overlapping portion of the rotary blade members a1. By sealing, airflow can be blocked more effectively. As a result, it is possible to further improve the heat retention function and moisturizing function of the cultivation facility 1. Further, since the seal portion a18 is formed of a flexible elastic member, it is elastically deformed by the pressing force to suitably close the gap, and as a result, the airflow can be effectively blocked.

Note that the electric power stored in the storage battery a19 can be taken out through a connector (not shown) and can be supplied to each mechanism. Thereby, convenience can be improved and the energy efficiency of the entire cultivation facility 1 can be improved.

<Configuration of control device>
As shown in FIG. 1, the control device C is an information processing device equipped with an information processing means C1 such as a CPU, ROM, and RAM, and a storage means C2 such as a semiconductor memory or HDD. Programs and data are processed by information processing means to realize various functions. It should be noted that the control device C is capable of acquiring time information indicating the current time using a clock section (not shown). Moreover, information Dt regarding the cultivation environment can be acquired from the measuring device Dt, and a control signal Cs can be transmitted to the louver device A by a communication means (not shown).

The storage unit C2 stores information necessary for the information processing unit C1 to rotationally control the solar panel P to perform illuminance adjustment control, which will be described later. For example, various types of information such as location information including latitude and longitude of the cultivation facility 1, date and time information including sunrise and sunset times, astronomical data indicating sun direction information, reference illuminance indicating the standard illuminance desirable for the growth of plants to be cultivated, etc. Information is stored. Further, information regarding the cultivation environment of the plants G in the cultivation facility 1 acquired from the measuring device D is appropriately stored.

The control device C configured as described above controls the motor M according to the cultivation environment of the cultivation facility 1 based on the information Dt regarding the cultivation environment measured by the measuring device D and various data stored in the storage means. By outputting the signal Cs and controlling the rotation of the solar panel P to appropriately change its posture, a cultivation environment suitable for the growth of the plants G is realized in the cultivation region Gr.

<Contact (interference) avoidance operation>
In the illuminance adjustment control of the control device C, which will be described later, the plurality of rotating blade members a1, a1, a1... are normally set so that the elevation angle direction F of each solar panel P, P, P... is an appropriate one. The entire structure is synchronously rotated so that it points in the right direction. However, since the plurality of rotating blade members a1, a1, a1... are configured such that the ends of the respective rotating blade members a1 overlap each other, if the entire rotating blade member a1 is rotated synchronously, the rotating blades When the solar panel P of the member a1 is in a substantially horizontal position, the ends contact (interference) with each other and rotation is hindered. Therefore, in such a case, the control device C synchronizes the first rotating blade member a11 and the second rotating blade member a12 in order to avoid contact (interference) between the ends of the rotating blade member a1. Rotation control is performed separately without any interference, and the contact (interference) avoidance operation described in detail below is performed.

As shown in FIG. 5(a), when the rotating blade member a1 is controlled to rotate in the reverse direction (clockwise) from the state where the rotation angle α of the solar panel P is >0°, the solar panel P When in a substantially horizontal position, the ends of the rotating blade members a1 come into contact with each other. Therefore, when controlling the rotating blade member a1 to further rotate in the reverse direction (clockwise) from the state where the solar panel P is in a substantially horizontal position, the control device C performs control according to the following procedure.

5(b) to 5(d), the rotating blade member a1 is rotated in the reverse direction (clockwise) from the state where the solar panel P is in a substantially horizontal position until the target rotation angle β2 is reached. This is an example of control related to contact (interference) avoidance operation in the case of dynamic control.

As shown in FIG. 5(b), the solar panel P1 of the first rotating blade member a11 is controlled to rotate in the normal rotation direction (counterclockwise) to a rotation angle α1. Thereby, the first rotating blade member a11 is retracted to a position where it does not come into contact with the second rotating blade member a12. In the example shown in FIG. 5(b), the rotation angle α1 is approximately 90°, but as long as the first rotation blade member a11 does not come into contact with the second rotation blade member a12, It may be about 90° or less.

Next, as shown in FIG. 5(c), the solar panel P2 of the second rotating blade member a12 is controlled to rotate in the reverse direction (clockwise) to a rotation angle β1. As a result, the solar panel P2 of the second rotating blade member a12 is allowed to overcome the substantially horizontal state in which contact with the first rotating blade member a11 occurs, and further, the solar panel P2 of the second rotating blade member a12 evacuate to a position where it will not come into contact with the In the example shown in FIG. 5(c), the rotation angle β1 is approximately 90°, but as long as the second rotation blade member a12 does not come into contact with the first rotation blade member a11, The angle may be about 90° or less.

Subsequently, as shown in FIG. 5(d), the solar panel P1 of the first rotating blade member a11 is controlled to rotate in the reverse direction (clockwise) to the target rotation angle β2. Thereafter, as shown in FIG. 5(e), the solar panel P2 of the second rotating blade member a12 is controlled to rotate in the normal rotation direction (counterclockwise) to the target rotation angle β2. . In this way, the rotation angle of the solar panel P of all the rotation blade members a1 can be set to the target rotation angle β2.

Also, as shown in FIG. 6(a), when rotating the rotating blade member a1 in the normal rotation direction (counterclockwise) from the state where the rotation angle β of the solar panel P is >0°, When the solar panel P assumes a substantially horizontal position, the ends of the rotating blade members a1 come into contact with each other. Therefore, the control device C performs control related to the contact avoidance operation according to the following procedure.

FIGS. 6(b) to 6(d) show that the solar panel P of the rotary blade member a1 is rotated in the normal direction until the solar panel P reaches the target rotation angle α2' from a substantially horizontal position. This is an example of control related to contact (interference) avoidance operation in the case of rotation control in the direction (counterclockwise).

As shown in FIG. 6(b), the solar panel P1 of the first rotating blade member a11 is controlled to rotate in the reverse direction (clockwise) to a rotation angle β1'. Thereby, the first rotating blade member a11 is retracted to a position where it does not come into contact with the second rotating blade member a12. In the example shown in FIG. 6(b), the rotation angle β1' is approximately 90 degrees, but as long as the first rotation blade member a11 does not come into contact with the second rotation blade member a12. , about 90° or less.

Next, as shown in FIG. 6(c), the solar panel P2 of the second rotating blade member a12 is controlled to rotate in the normal rotation direction (counterclockwise) to a rotation angle α1'. . As a result, the solar panel P2 of the second rotating blade member a12 is allowed to overcome the substantially horizontal state in which contact with the first rotating blade member a11 occurs, and further, the solar panel P2 of the second rotating blade member a12 evacuate to a position where it will not come into contact with the In the example shown in FIG. 6(c), the rotation angle α1' is approximately 90 degrees, but as long as the second rotation blade member a12 does not come into contact with the first rotation blade member a11. , about 90° or less.

Subsequently, as shown in FIG. 6(d), the solar panel P1 of the first rotating blade member a11 is controlled to rotate in the normal rotation direction (counterclockwise) to achieve the target rotation angle α2'. shall be. Thereafter, as shown in FIG. 6(e), the solar panel P2 of the second rotating blade member a12 is controlled to rotate in the reverse direction (clockwise) to the target rotation angle α2'. In this way, the rotation angle of the solar panel P of all the rotation blade members a1 can be set to the target rotation angle α2'.

<Illuminance adjustment control>
The control device C has a plurality of attitude control patterns for the solar panel P, and uses the attitude control patterns to control the rotation of the rotating blade member a1. This embodiment includes the following four attitude control patterns. Note that each attitude control pattern is stored in advance in the storage means C2 of the control device C, and when determining the attitude control pattern, the control device C stores the direction of the sun SN and the incident direction of the sunlight L in the storage device. This can be determined by referring to astronomical data indicating solar azimuth information stored in C2.

The control device C performs illuminance adjustment control by switching each attitude control pattern depending on the situation. Here, the illuminance adjustment control refers to control in which the control device C controls the louver device A to adjust the illuminance in the cultivation area Gr in the cultivation facility 1.

FIG. 7 is a schematic right side view of the plurality of rotating blade members when the solar panel P is in a substantially horizontal position.
As the first attitude control pattern, the horizontal attitude control Pa is controlled so that the solar panels P of all the rotary blade members a1 are in a substantially horizontal attitude, as shown in FIG. Thereby, the ends of the rotary blade members a1 overlap each other, thereby blocking airflow and improving the heat retention function and moisturizing function of the cultivation facility 1. Moreover, since solar radiation is also blocked at the same time, the illuminance within the cultivation area Gr of the cultivation facility 1 can be minimized.

As the second attitude control pattern, the maximum shading attitude control Pb constantly links the elevation angle direction F of the solar panel P with the position of the sun SN, and as shown in FIGS. The elevation angle direction F of the solar panel P of member a1 is controlled to face the sun SN. At this time, the light shielding surface of the solar panel P becomes perpendicular to the direction of incidence of sunlight L. In addition, in FIGS. 8 and 9, one simplified solar panel P is illustrated for convenience of explanation, and in FIG. 8, the case where the sun SN is on the east side of the cultivation facility 1 is illustrated. 9, the case where the sun SN is on the west side of the cultivation facility 1 is illustrated.

As the third attitude control pattern, the minimum shading attitude control Pc constantly links the elevation direction F of the solar panel P with the position of the sun SN, and as shown in FIGS. The elevation angle direction F is controlled to be perpendicular to the direction of incidence of sunlight L. At this time, the light shielding surface of the solar panel P becomes parallel to the direction of incidence of sunlight L. Thereby, the amount of light shielding per one rotating blade member a1 can be minimized, and the illuminance in the cultivation area Gr in the cultivation facility 1 can be maximized.

FIG. 8 is an explanatory diagram for explaining the operation of the solar panel P when the sun is on the east side, and FIG. 9 is an explanatory diagram for explaining the operation of the solar panel P when the sun is on the west side.
As the fourth attitude control pattern, the shading amount adjustment attitude control Pd always links the elevation angle direction F of the solar panel P with the position of the sun SN, and as shown in FIGS. 8 and 9, the solar panel P From the state where the elevation angle direction F is perpendicular to the direction of sunlight incidence (the state of minimum shading posture control Pc), adjust the adjustment angle θCO (0°<θCO<90°) in the direction that increases the shade area S. The orientation of the solar panel P is controlled so that the solar panel P is rotated in the forward direction (counterclockwise) or in the reverse direction (clockwise). In addition, the shade area S refers to the area of the shade generated on the ground surface of the cultivation area Gr by the light shielding of the solar panel P.

Here, the shading rate of the rotary blade member a1 in each posture of the solar panel P is determined by assuming that the shading rate of the solar panel P at the maximum shading posture control Pb is 100%, and the shade area Smax at the maximum shading posture control Pb. and the shade area S (Sx) in each posture. That is, the shading rate R in each posture of the solar panel P can be determined by the following formula.
Shading rate R (%) = (shade area Sx/maximum shade area Smax) x 100
Note that when the minimum light shielding posture control Pc is performed, the shade area S (Smin) becomes the minimum, and the light shielding rate R (Rmin) at this time is, for example, about 10%.

More specifically, when the sun SN is on the east side as shown in FIG. 8, the direction of the adjustment angle θCO that increases the shade area S is in the reverse direction (clockwise), When SN is on the west side, the rotation direction is normal (counterclockwise). Thereby, by controlling the magnitude of this adjustment angle θCO, it is possible to adjust the amount of light blocking (light blocking rate) per one rotary blade member a1, and as a result, the amount of light blocking (light blocking rate) of the louver device A can be adjusted. ), the illuminance in the cultivation area Gr in the cultivation facility 1 can be adjusted.

Next, a method for determining the adjustment angle θCO will be explained.
The control device C determines θCO by comparing the reference illuminance W1 stored in the storage means with the actual illuminance W2 measured by the measuring device D. Here, the reference illuminance W1 is a reference value of illuminance suitable for the growth of the plant G to be cultivated, recorded in chronological order. Information regarding this reference illuminance W1 is stored in advance in the storage means C2 of the control device C, and the user can set an arbitrary value in advance. Further, the actual illuminance W2 is an actual value of the illuminance in the cultivation facility 1 measured by the measuring device D at a predetermined time interval, and the information regarding the actual illuminance W2 is the illuminance measured by the measuring device D. When C obtains the information, it is stored in the storage means C2 of the control device C each time.

FIG. 10 is an explanatory diagram for explaining the relationship between reference illuminance and actual illuminance.
As an example, FIG. 10 shows a graph in which the horizontal axis is time, the vertical axis is illuminance (W/m ² ), and the reference illuminance W1 and actual illuminance W2 of the plant G to be cultivated are shown as solid lines. ing. The control device C determines whether the illuminance is excessive or insufficient for the growth of the plants G by comparing the reference illuminance W1 stored in advance in the storage means C2 and the actual illuminance W2 measured by the measuring device D. It is possible. For example, in the example of FIG. 10, the reference illuminance W1 exceeds the actual illuminance W2 from 6:00 to 14:00, and it can be determined that the illuminance suitable for growing the plants G is insufficient. Further, between the time 14:00 and the time 19:00, the reference illuminance W1 is lower than the actual illuminance W2, and it can be determined that the actual illuminance W2 exceeds the illuminance suitable for growing the plants G.

In addition, when a plurality of measuring devices D are arranged in the cultivation area Gr, the control device C acquires information regarding the cultivation environment from the plurality of measuring devices D, calculates the average value, and calculates the above-mentioned actual illuminance. By using this average value for W2, it is possible to judge the cultivation environment of the entire cultivation region Gr.

When the control device C switches to the light shielding amount adjustment posture control Pd, the control device C sets the adjustment angle θCO to an initial value (for example, 30°) and controls the orientation of the solar panel P (step S1). Next, the reference illuminance W1 stored in the storage means is compared with the latest actual illuminance W2, and if the reference illuminance W1<actual illuminance W2, the adjustment angle θCO is increased by a predetermined amount (for example, 5 degrees), and the reference illuminance W1 >If the actual illuminance W2, the adjustment angle θCO is decreased by a predetermined amount (for example, 5°), and if the reference illuminance W1=actual illuminance W2, the adjustment angle θCO is not changed (step S2). After step S1, the control device C repeats step S2 at predetermined time intervals to appropriately adjust the adjustment angle θCO so that the actual illuminance W2 approaches the reference illuminance W1 while the light shielding amount adjustment posture control Pd is being executed. You can adjust the illuminance while correcting it to a suitable value.

Here, when the adjustment angle θCO≦0° as a result of the correction of the adjustment angle θCO through the repeated control in step S2, the control device C determines that the situation in which the actual illuminance W2 is lower than the reference illuminance W1 continues. Therefore, the minimum light shielding posture control Pc is performed until the reference illuminance W1<actual illuminance W2. Thereafter, when the reference illuminance W1<actual illuminance W2, the process returns to step S1, returns the adjustment angle θCO to the initial value, and performs the light shielding amount adjustment posture control Pd.

Furthermore, as a result of the correction of the adjustment angle θCO through the repeated control in step S2, the control device C causes the actual illuminance W2 to exceed the reference illuminance W1 when the adjustment angle θCO exceeds a predetermined threshold value (for example, 60°). Since it is determined that the current situation is continuous, the maximum light shielding posture control Pb is performed until the reference illuminance W1>actual illuminance W2. Thereafter, when the reference illuminance W1>actual illuminance W2, the process returns to step S1, returns the adjustment angle θCO to the initial value, and performs the light shielding amount adjustment posture control Pd.

By repeating the above control, if the actual illuminance W2 is insufficient than the illuminance suitable for growing the plants G (in the example of FIG. 10, between 6 o'clock and 14 o'clock), the rotating blade member a1 blocks the light. (or the shading rate R) is gradually decreased to increase the illuminance of the cultivation area Gr, and when the actual illuminance W2 exceeds the illuminance suitable for growing the plants G (in the example of FIG. 10, (from time 14:00 to time 19:00), the amount of light shielding (or the light shielding rate R) by the rotating blade member a1 is gradually increased to lower the illuminance of the cultivation region Gr. Thereby, in the light shielding amount adjustment posture control Pd, the rotation of the rotary blade member a1 is controlled so that the illuminance suitable for growing the plants G is realized using sunlight. As a result, sunlight entering the room can be appropriately blocked, making it possible to precisely adjust the indoor illuminance.

Next, the relationship between the diurnal movement of the sun SN and the illuminance adjustment control and contact avoidance operation of the control device C described above will be explained. FIG. 11 is a diagram in which the orbit of the sun SN in the diurnal movement of one day is simplified for the purpose of explanation. In the following explanation, as shown in FIG. 11, the meridian direction of the sun SN is referred to as DS, the angle of the sun from the horizon from AM to noon as θAM, and the angle from the horizon from noon to AM to θPM. . Also, position (A) is sunrise (time: T0), position (B) is in the morning (time: T1), position (C) is noon (midnight) (time: T2), and position (D) is in the afternoon (time: T2). Time: T3) and position (E) indicate the position of the sun SN at sunset (time: T4).

At night, the control device C performs horizontal attitude control Pa. Thereby, the cultivation facility 1 can exhibit its heat retention function and moisturizing function under conditions where the indoor temperature tends to drop due to the influence of a drop in outside air temperature.

When the sun SN is at position (A) and sunrise time T0 arrives, the control device C switches from horizontal attitude control Pa to light shielding amount adjustment attitude control Pd. As a result, the amount of shading is changed from the state of horizontal posture control Pa, which improves the heat retention function and moisturizing function of the cultivation facility 1 at night, to the amount of shading during the day to adjust the illuminance of the cultivation area Gr to a level suitable for plant growth. The process moves to adjustment posture control Pd.

When the sun SN is at position (B), the control device C performs the light shielding amount adjustment attitude control Pd at time T1 in the morning (see FIG. 8). Thereby, the cultivation area Gr can be adjusted to the sunlight intensity suitable for the growth of plants.

When the sun SN is at position (C), at noon time T2, the control device C performs a contact avoidance operation of the rotating blade member a1 according to the procedure shown in FIGS. 5(b) to 5(e). control like this. This is because the direction of incidence of sunlight L changes from the east side to the west side at noon (midsummer time), so it is necessary to control the rotation of the solar panel P. Thereby, the light shielding amount adjustment attitude control Pd can be suitably continued before and after noon (midsummer time).

When the sun SN is at position (D), the control device C continues the light shielding amount adjustment attitude control Pd at time T3 in the morning (see FIG. 9). Thereafter, when the sun SN is at position (D) and sunset time T4 comes, the control device C switches to horizontal attitude control Pa. Thereby, at night, the louver device A can block airflow and improve the heat retention function and moisturizing function of the cultivation facility 1.

Further, when switching to the horizontal posture control Pa, the control device C simultaneously controls the rotating blade member a1 to perform a contact avoidance operation according to the procedure shown in FIGS. 6(b) to 6(e). This is because at the sunrise time T0 of the next day, when switching to the light shielding amount adjustment attitude control Pd, the incident direction of the sunlight L has been switched from the west side to the east side. Thereby, the light shielding amount adjustment posture control Pd can be started smoothly.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention described in the claims, and these are also included within the scope of the present invention. Needless to say.

FIG. 12 is a schematic right side view showing another embodiment of the plurality of rotating blade members a1 when the solar panel P is in a substantially horizontal position. As shown in FIG. 12, the solar panel P' of the rotating blade member a1' may have a gentle curvature. As a result, the area of the light-shielding surface of the solar panel P' can be increased to increase the amount of power generation, and the seal part a18 is locked with the upper end of the adjacent rotating blade member a1', making it more difficult for gaps to occur. It can be a structure. Furthermore, both ends of the rotating blade member a1' may be bent to provide a return portion that projects upward. Thereby, it is possible to create a structure in which the solar panel P' can more easily block light and generate power.

Further, in the above embodiment, a configuration is shown in which the rotation of the solar panel P of the rotating blade member a1 is controlled based on the illuminance measured by the measuring device D, but the invention is not limited to this. The optical panel P may be rotationally controlled. Furthermore, a configuration has been shown in which the solar panel P is rotationally controlled by determining whether the illuminance is excessive or insufficient by comparing the standard illuminance W1 and the actual illuminance W2. The solar panel P may be configured to be rotationally controlled by comparing the magnitude of the integrated actual illuminance W2 and determining whether the illuminance is excessive or insufficient. The same applies to the amount of solar radiation.

Further, in the above embodiment, the configuration is shown in which the rotation of the solar panel P of the rotating blade member a1 is controlled based on the illuminance measured by the measuring device D, but the invention is not limited to this. The rotation of the solar panel P of the rotating blade member a1 can be controlled based on temperature, humidity, carbon dioxide concentration, etc. In this case, for temperature, humidity, carbon dioxide concentration, etc., reference values are stored in the storage unit C2 in chronological order instead of the reference illuminance W1 shown in FIG. 10, and the actual temperature measured by the measuring device D is , humidity, carbon dioxide concentration, etc., and the rotation of the solar panel P of the rotary blade member a1 can be controlled.

For example, by controlling the rotation of the solar panel P, the larger the gap between the rotating blade members a1, the higher the air permeability of the louver device A, and the smaller the gap between the rotating blade members a1, the higher the air permeability of the louver device A. Since the air permeability decreases, when the reference value stored in the storage unit C2>actual temperature, humidity, carbon dioxide concentration, etc. measured by the measuring device D, the temperature, humidity, carbon dioxide concentration, etc. of the cultivation area Gr. In order to increase the carbon concentration, etc., the gap between the rotating blade members a1 is narrowed to reduce breathability, and the reference value stored in the storage section C2 < the actual temperature and humidity measured by the measuring device D. In order to reduce the temperature, humidity, carbon dioxide concentration, etc. of the cultivation area Gr when measuring values such as , carbon dioxide concentration, etc., it can be configured to narrow the gap between the rotary blade members a1 to increase air permeability.

Moreover, at this time, when lowering the temperature, humidity, carbon dioxide concentration, etc. of the cultivation region Gr, a fan capable of blowing air from the bottom to the top of the cultivation region Gr may be provided to blow the air. In addition, when increasing the temperature, humidity, carbon dioxide concentration, etc. of the cultivation area Gr, various devices that increase these values are installed (for example, a carbon dioxide supply device, etc.) to promote the increase in these values. Good too.

In addition, during the light shielding amount adjustment posture control Pd, if the measured values such as temperature, humidity, carbon dioxide concentration, etc. In order to reduce the temperature and create a cultivation environment suitable for the growth of plants G, the ventilation of the cultivation facility 1 is switched to maximum shading posture control Pb until the measured values of temperature, humidity, carbon dioxide concentration, etc. fall below predetermined threshold values. It may be configured to improve performance. In this way, by adjusting the values of temperature, humidity, carbon dioxide concentration, etc. by controlling the louver device A, it is possible to reduce the running cost of the entire cultivation facility 1, and to control the growth rate of the plants G to shorten the shipping time. Can be adjusted.

Alternatively, the cultivation region Gr may be divided into a plurality of sections, the louver device A and the measuring device D may be arranged for each section, and the control device C may be configured to finely control the illuminance etc. for each section.

Further, the shape of the seal portion a18 is such that the cross-sectional shape of the surface is approximately U-shaped, but is not limited to this. Various shapes can be adopted, such as a shape or a spatula shape.

Moreover, in the said embodiment, the example in which the cultivation facility 1 was provided with the housing H was demonstrated. However, regarding the cultivation facility 1, the housing H is not an essential configuration, and the louver device A according to the present invention can be applied even when the cultivation area Gr is not shielded from the outside, such as in open field cultivation, for example. can.
