When the crop 100 grows, the stems, leaves 100a, etc. of the crop 100 grow upward from the pot 105 . Roots 100b of crop 100 grow downward from pot 105 . The roots 100 b of the crop 100 absorb the nutrient solution inside the tray inner space T of the tray 5 .

The liquid supply unit 6 supplies water (nutrient solution) to the inside of the tray 5 . The liquid supply unit 6 injects the nutrient solution into the tray 5 . The liquid supply unit 6 has a nozzle 61 arranged inside the tray 5 . As shown in FIG. 3 , one end of an air hose 62 and one end of a nutrient solution hose 63 are connected to the nozzle 61 .

The other end of the air hose 62 is connected to a compressed air supply source 67 (see FIG. 1) such as an air compressor or an air cylinder. The air hose 62 supplies compressed air supplied from a compressed air supply source 67 to the nozzle 61 . The other end of the nutrient solution hose 63 is connected to a nutrient solution tank 68 (see FIG. 1). The nutrient solution tank 68 stores a nutrient solution in which water, fertilizer (liquid fertilizer) and the like are mixed in a predetermined composition. The nutrient solution hose 63 supplies the nutrient solution sucked from the nutrient solution tank 68 by a pump (not shown) to the nozzle 61 . The compressed air supply source 67 and the nutrient solution tank 68 may be arranged inside the container 2 or may be arranged outside the container 2 .

The nozzle 61 mixes the compressed air supplied from the air hose 62 and the nutrient solution supplied from the nutrient solution hose 63 and injects the mixture into the tray inner space T. The particle size of the nutrient solution injected from the nozzle 61 is not limited at all, and may be in the form of so-called droplets or in the form of mist.

Here, the liquid supply unit 6 sprays the nutrient solution from the nozzles 61 by the later-described growth condition control unit 93 so that the humidity in each tray 5 becomes a predetermined humidity (for example, 100%). It is preferable to control the amount, injection duration, injection timing, and the like.

As shown in FIGS. 2 and 3, the light source 7 irradiates the crop 100 in the pot 105 supported by the tray 5 with the light B. As shown in FIG. As the light source 7, for example, an LED light source can be used. The wavelength of the light B emitted by the light source 7 may be appropriately set according to the crop 100 . The light source 7 is arranged above, for example, the trays 5 supported by the shelves 42 on each stage. The light source 7 is arranged, for example, on the lower surface of another shelf member 42 or top plate 44 positioned above the tray 5 . Irradiation of the light B by the light source 7 is controlled by a growth condition control section 93, which will be described later.

The air hose 62, the nutrient solution hose 63, and the power line 72 have a predetermined extra length so as not to hinder the movement of the shelves 4 when the shelves 4 are moved along the guides 3, as will be described later. .

As shown in FIG. 1, each of the shelves 4 as described above is movable along the guide 3 in the first direction D1.
For example, when performing work such as harvesting, observing, tending, inspecting, or maintaining the crops 100 on each shelf 4, the plurality of shelves 4 are moved along the guides 3 in the first direction D1, and the adjacent shelf 4 is moved. The interval between them can be widened (the state of the two-dot chain line in FIG. 1). Thereby, a space for a person to enter and work can be secured in the gap Sk between the adjacent shelves 4. - 特許庁

In addition, when a person does not enter between the adjacent shelves 4, the plurality of shelves 4 can be moved along the guide 3 in the first direction D1 to narrow the interval between the adjacent shelves 4 (see FIG. 1). solid line in ). As a result, the space other than the portion where the plurality of shelves 4 are assembled can be effectively used for various operations.
As shown in FIG. 3, when the space between the adjacent shelves 4 is narrowed, the light B emitted from the light source 7 on one shelf 4 is diffused, thereby causing the crops held on the trays 5 on the other shelf 4 to grow. 100 can also be irradiated with the light B. FIG. As a result, the crop 100 can be efficiently irradiated with the light B from the light source 7 .

As shown in FIGS. 1 and 2, the photographing unit 8 photographs the crops 100 on each shelf 4 . The photographing unit 8 includes rails 81 and a photographing device 82 .

The spectral filter 84 includes multiple types of filters (not shown). Each filter transmits light in a defined wavelength band. The plurality of types of filters differ from each other in the wavelength range of the transmitted light. The spectral filter 84 is used by selecting an appropriate wavelength band filter from among a plurality of types of filters. By capturing an image through the spectral filter 84 with the camera 83, the fluorescence intensity of the light can be observed based on the captured image. As a result, based on the images (including videos) taken by the camera 83, it is possible to detect the withering of crops and to observe a substance called chlorophyll fluorescence that can measure the rate of photosynthesis.

The moving mechanism 85 includes a guide roller (not shown) that meshes with the rail 81 and a motor (not shown) that drives the guide roller to rotate. The moving mechanism 85 rotates the guide roller by operating the motor, and moves the photographing device 82 along the rail 81 . The operation of the motor is controlled by an imaging control section 92, which will be described later.

The imaging control unit 92 controls the moving mechanism 85 to move the imaging device 82 along the rails 81 . When moving the photographing device 82 along the rail 81, the photographing control unit 92 causes the photographing device 82 to search for the marker 48 provided on each shelf 4, as will be described in detail later. When the marker 48 is found, the imaging control section 92 positions the imaging device 82 with respect to the shelf 4 on which the marker 48 is provided.

The growing condition control unit 93 controls the growing conditions of the crops 100 on each shelf 4 based on the images captured by the camera 83 of the imaging device 82 . For example, based on the image captured by the camera 83, the speed of photosynthesis in each tray 5, the size, height, color, etc. of the stem and leaves of the crop 100 are measured, and the degree of growth of the crop 100 is quantitatively evaluated.

The growing condition control unit 93 controls the growing conditions of the crop 100 based on the evaluation result of the degree of growth of the crop 100 and a preset program. The growth conditions of the crop 100 controlled by the growth condition control unit 93 include, for example, the amount (spray amount) of the nutrient solution supplied to the tray 5 of each shelf 4, the water supply duration, the water supply time interval, and the like in the liquid supply unit 6. be.

FIG. 5 is a flow chart showing the flow of the control method of the photographing device in the photographing control section.
The photographing control unit 92 of the control device 9 automatically performs the following processing at preset time intervals in order to photograph the growing conditions of the crops 100 on each shelf 4 .
As shown in FIG. 5, the photographing control unit 92 first confirms whether or not all the shelves 4 have been photographed (step S11).

As a result, if all the shelves 4 have not been photographed (No in step S11), the following step S12 is performed in order to search for the marker 48 provided on the shelf 4. FIG. That is, the photographing control unit 92 advances (moves) the photographing device 82 along the rail 81 by a predetermined distance (for example, 30 cm) in a direction away from the preset initial position of the photographing device 82 (step S12). . Subsequently, the photographing control unit 92 causes the camera 83 to photograph at the post-movement position (step S12). The camera 83 transmits the photographed image to the photographing control section 92 .

When the image captured by the camera 83 is received, the image capturing control unit 92 performs image processing to check whether the marker 48 is recognized in the image captured by the camera 83 (step S13).

If the marker 48 is not recognized in the image (No in step S13), the imaging control unit 92 returns to step S12 and further moves the imaging device 82 along the rail 81 in the direction away from the initial position. The photographing control unit 92 repeats steps S12 and S13 until the marker 48 is recognized in the image photographed by the camera 83 .

In step S13, if the marker 48 is recognized in the image captured by the camera 83 (Yes in step S13), the capturing control unit 92 determines that the recognized marker 48 is positioned at the center of the image (in the first direction D1). center) (step S14).

Specifically, when the marker 48 is shifted away from the initial position in the first direction D1 with respect to the center of the image, the photographing device 82 is moved further along the rail 81 in the direction away from the initial position. Let In this case, the amount of movement of the photographing device 82 in the first direction D1 is preferably smaller than the amount of movement of the photographing device 82 in step S12 (for example, 5 cm).
Further, when the marker 48 is deviated from the center of the image in the first direction D1 in a direction approaching the initial position, the photographing device 82 is moved along the rail 81 in a direction approaching from the initial position. In this case, the amount of movement of the photographing device 82 in the first direction D1 is also preferably smaller than the amount of movement of the photographing device 82 in step S12 (for example, 5 cm).

In step S15, the photographing control unit 92 causes the camera 83 to continue photographing after adjusting the position of the photographing device 82 as described above.
The photographing control unit 92 repeats steps S14 and S15 until the marker 48 in the photographed image reaches the center of the image in the first direction D1. Note that the marker 48 is not limited to the complete center position of the image in the first direction D1, and the position of the photographing device 82 is adjusted so that the center of the image in the first direction D1 is within a predetermined range.
