Description

Smart ginseng hydroponics system {Smart water culture system for ginseng}

The present invention relates to a smart ginseng hydroponics system, and more particularly, to a smart ginseng hydroponics system that can promote the growth of ginseng and improve the quality of ginseng by individually adjusting the amount of light according to the growth rate of ginseng. .

In general, hydroponics (水耕栽培) is a method of growing plants using a nutrient solution made of water and water-soluble nutrients using an artificial medium or container that can support a plant without using soil.

The advantage of hydroponics is that it is possible to directly observe the condition and growth of the roots, it can continuously produce uncontaminated clean vegetables or plants, and it can be commercially mass-produced.

On the other hand, ginseng is mainly cultivated in traditional methods such as soil cultivation, which usually takes 4-6 years to cultivate, so the cultivation period is too long and the cost is excessive. Therefore, price competitiveness is very weak.

In addition, ginseng suffers from root rot, so it is difficult to cultivate it in one place, so there are many difficulties in compensating the soil.

Therefore, it is necessary to spray a large amount of soil fungicide, which causes many problems, such as side effects and increased cost burden on farms. Accordingly, efforts have been made to improve the quality of ginseng while shortening the cultivation period through hydroponics.

As ginseng grows, the required PPDF (Photosynthetic Photon Flux Density) varies. That is, the PPFD value required for the growth of ginseng is 60 μmol in the early stage of growth, 100 μmol in the middle of growth, and 120 μmol at the end of growth.

On the other hand, the lighting time required for growth is needed a lot in the early stage of growth and gradually decreases at the end of growth.

In this way, the amount of light required and the lighting time are different depending on the growth of ginseng, but in actual hydroponics, all the ginsengs are irradiated with the same lighting.

Since the growth rate of each individual ginseng is slightly different, if the same amount of light is supplied at the same time, there is a problem that the individual cannot grow as a good product due to the difference between the growth rate and the PPFD value. In other words, if most of the individuals are judged to be in the mid-growth stage and the LED brightness is raised to 100 μmol, the photosynthetic efficiency decreases in the slow-growing individuals, and the fast-growing individuals do not grow properly leaves and grow long like bean sprouts. occurs

Hereinafter, the present invention will be described in detail with reference to a preferred embodiment of the present invention and the accompanying drawings, but the same reference numerals in the drawings will be described on the premise that they refer to the same components.

When it is said that any one component "includes" another component in the detailed description or claims of the invention, it is not construed as being limited to that component only unless otherwise stated, and other components are not construed as being limited thereto. It should be understood that more may be included.

1 is a schematic diagram schematically showing the front configuration of a ginseng hydroponic cultivation system 1 according to the present invention, FIG. 2 is a schematic diagram schematically showing an external control structure of the ginseng hydroponic cultivation system 1, FIG. 3 is It is a schematic diagram schematically showing the internal control structure of the ginseng hydroponics system (1).

As shown, in the ginseng hydroponics system 1 according to the present invention, a plurality of ginseng cultivation tanks 100 in which ginseng (A) is grown, and a plurality of ginseng cultivation tanks 100 are grown so that a plurality of ginseng cultivation tanks 100 are floated on the upper surface. A temperature control water tank 200 accommodating the water tank 100, a support frame 300 disposed to cover the upper portion of the temperature control water tank 200, and each ginseng (A) coupled to the ceiling of the support frame 300 To determine the size of ginseng based on the lighting unit 400 for irradiating by differentially controlling the amount of light according to the growth state of the ginseng, the camera 500 for photographing the ginseng (A), and the ginseng image taken by the camera 500 It includes a ginseng size determination unit 600 and a control unit 700 for controlling the lighting unit 400 based on the size of ginseng determined by the ginseng size determination unit 600 .

The ginseng cultivation tank 100 accommodates a certain number of ginseng (A). For example, in the present invention, a pair of ginseng (A) is disposed in one ginseng cultivation tank 100 in the width direction. The inside of each ginseng cultivation tank 100 is filled with the nutrient solution (B). A ginseng fixture 110 is disposed on the upper portion of the ginseng cultivation tank 100 .

The ginseng fixture 110 supports the position of the ginseng (A) so that the ginseng (A) does not fall into the nutrient solution (B), the stem and leaves are exposed to the air, and only the root can grow in a state immersed in the nutrient solution (B). do. The ginseng fixing body 110 is made of a material having elasticity, such as a sponge, and an incision or a groove is formed in the middle region so that the position of the ginseng (A) can be fixed.

Here, in the case of ginseng (A), which is designed to grow only a set number, for example, a pair of ginseng (A) in one ginseng cultivation tank 100, unlike other plants, it is composed of polysaccharides, so it is weak against the penetration of bacteria. If one suffers from a disease or injury, the ginseng root contained in the same nutrient solution (B) suffers the same damage, resulting in poor growth or must be destroyed.

Accordingly, if the ginseng cultivation tank 100 is enlarged and a large number of ginseng is put in and grown at once, if a disease occurs in one ginseng, a large number of ginseng must be discarded, so the damage may be very large. In order to prevent such a case, the ginseng cultivation tank 100 of the present invention is formed in a small size so that only a pair of ginseng (A) can be accommodated.

A nutrient solution temperature sensor 120 is provided inside any one of the plurality of ginseng cultivation tanks 100 to sense the temperature of the nutrient solution B and transmit it to the control unit 700 .

The temperature control water tank 200 is formed in a size that can accommodate all of the plurality of ginseng cultivation tanks 100 , and functions to maintain a constant temperature of the ginseng cultivation tank 100 . The inside of the temperature control water tank 200 is filled with water (C), and a plurality of ginseng cultivation tanks 100 are disposed in a state of being floated on top of the water (C).

Depending on the root environment of ginseng, the stem may or may not rise. In other words, since root damage affects the entire ginseng, controlling the environment around the root is an important factor for cultivating high-quality ginseng. In particular, ginseng roots react very sensitively to temperature changes, and if the temperature change is large, not only cannot grow under severe stress, but also rot and die in severe cases.

The temperature control water tank 200 accommodates a plurality of ginseng cultivation tanks 100 therein, and controls the temperature of the ginseng cultivation tank 100 in an indirect manner. The temperature control water tank 200 regulates the temperature of the ginseng cultivation tank 100 by circulating water (C).

A supply pipe 210 for supplying water (C) to the inside is connected to one side of the temperature control water tank 200, and a discharge pipe 220 for discharging water (C) is connected to the other side. The supply pipe 210 and the discharge pipe 220 are coupled to the water storage tank 230 . A pump 240 is provided in the supply pipe 210 , and a water temperature sensor 260 and a water level sensor 270 are provided in the temperature control water tank 200 , respectively. A temperature control means 250 is provided on the upper portion of the water storage tank 230 to cool or heat the temperature of the water (C).

The controller 700 controls the temperature control water tank 200 so that the temperature of the nutrient solution B is maintained in the range of 16°C to 20°C. When the current temperature of the nutrient solution (B) measured by the nutrient solution temperature sensor 120 exceeds 20 °C, the temperature of the water (C) is controlled to decrease. When there is no difference between the temperature of the water measured by the water temperature sensor 260 and the current temperature of the nutrient solution (B), the control unit 700 drives the temperature control means 250 to supply the water in a lowered state to supply the nutrient solution ( Let the temperature of B) be adjusted to 16℃~20℃.

Conversely, when the current temperature of the nutrient solution (B) is lower than 16°C, the temperature of the nutrient solution (B) is adjusted to 16°C-20°C by supplying the water at a high temperature.

In addition, the control unit 700 drives the pump 240 so that the water level of the water (C) is constantly maintained based on the level of the water (C) sensed by the water level sensor 270 .

By the function of the temperature control water tank 200, the temperature of the nutrient solution (B) is kept constant for four seasons including summer and winter, thereby minimizing the influence of ginseng roots due to temperature change, thereby improving the quality of ginseng.

The support frame 300 is disposed to cover the temperature control water tank 200 on the upper portion of the temperature control water tank 200 . A lighting unit 400 is provided on the upper inner side of the support frame 300 , and blowing fans 310 are provided on both side walls to ventilate the inside.

A control unit 700 is provided outside the support frame 300 , and a power supply line not shown in the drawing is disposed.

The lighting unit 400 is provided on the ceiling of the support frame 300 and differentially supplies an amount of light suitable for the growth degree of each ginseng A in the ginseng cultivation tank 100 under the control of the control unit 700 . 4 is a front view illustrating a process in which the lighting unit 400 of the present invention irradiates light to the ginseng cultivation tank 100, FIG. 5 is a perspective view illustrating the configuration of the lighting unit 400, and FIG. 6 is the lighting unit 400 ) is a side view showing the process of irradiating light to the ginseng cultivation tank (100).

4 to 6 , the lighting unit 400 is coupled to the light emitting member 410 for irradiating light, the substrate frame 420 supporting the plurality of light emitting members 410 and the substrate frame 420 . The light-emitting member 410 adjusts the angle at which the light emitting member 410 irradiates light with a pair of ginseng (A) to control the amount of light supplied to the ginseng (A). Includes a reflective member driving unit 440 for adjusting the angle of.

The light emitting member 410 irradiates light to facilitate the growth of ginseng by photosynthesis. The light emitting member 410 may be provided with an LED. The light emitting member 410 is coupled to the substrate 411 to receive power to emit light. A plurality of light emitting members 410 are provided in the substrate frame 420 along the longitudinal direction. The plurality of light emitting members 410 are preferably disposed in the middle region of the pair of ginseng (A) on the upper portion of each ginseng cultivation tank (100).

Photosynthesis means 'synthesis using light', and for plants, which are photosynthetic organisms, it means that light is used as energy when synthesizing organic materials. Photosynthesis refers to the synthesis of glucose from carbon dioxide and water using light energy.

Photosynthesis is divided into a light reaction that requires light (photophosphorylation) and a dark reaction that does not require light. The light reaction converts light energy into ATP and NADPH ₂ in the Grana of the chloroplast to supply energy, inorganic phosphoric acid, reducing power and hydrogen to the Calvin cycle of the dark reaction, and the dark reaction synthesizes glucose using the ATP and NADPH ₂ in the stroma of the chloroplast By doing so, the bioenergy necessary for growth is obtained.

In addition, plant cells produce a large amount of ATP, a chemical energy, by decomposing glucose in the cytoplasm and mitochondria through glycolysis, TCA cycle, and chemosmotic phosphorylation. It efficiently obtains the energy necessary for growth.

Among these photosynthetic processes, the length of day and Photosynthetic Photon Flux Density (PPFD) are the factors that have the most influence on the vegetative and reproductive growth of plants. growth is different.

In addition, plants photosynthesize in the 380~760nm region including the visible light region, and the radiation energy in the wavelength range where photosynthesis occurs is called photosynthetically active radiation (PAR), and each plant has a broadband (wavelength) and The photosynthetic effective photon mass is different.

Therefore, in many cases, greenhouses or plant factories cannot directly utilize sunlight, so it is very important to secure the light necessary for crop growth, and in this case, artificial lighting is used.

The ginseng hydroponics system (1) of the present invention is provided with an artificial light emitting member 410 to provide PPFD necessary for the growth of ginseng (G), and from this light emitting member 410 to each ginseng (A). A light amount adjusting and reflecting member 430 is provided so that the amount of irradiated light matches the growth rate of the corresponding ginseng (A). Accordingly, the amount of irradiated light is adjusted to match the size of each ginseng A1 and A2 having different growth rates, so that the ginseng A1, A2 maintains the optimum growth rate and improves the quality.

Here, the PPFD value required for the growth of ginseng is 60 μmol in the early stage of growth, 100 μmol in the middle of growth, and 120 μmol at the end of growth.

On the other hand, the lighting time required for growth is needed a lot in the early stage of growth and gradually decreases at the end of growth.

As shown in FIG. 5 , the light emitting member 410 is provided as an LED element, and the light quantity adjusting reflective member 430 is formed in a hemispherical shape surrounding the light emitting member 410 . The light amount control reflective member 430 is provided to be rotatable left and right as shown in FIG. 6 . Since the light quantity control reflective member 430 is formed in a hemispherical shape, the light generated from the light emitting member 410 is concentrated and supplied to a pair of ginseng without being dispersed to the outside.

In addition, the light amount control reflective member 430 is rotatably provided to reflect the angle of the light (L) irradiated from the light emitting member 410 when the growth rate of a pair of ginseng is different, so that the PPFD of the pair of ginseng is more Light (L) is irradiated toward ginseng, which is required a lot.

The light amount control reflective member 430 is formed of a material that can reflect the light (L). As shown in FIG. 5 , a pair of frame insertion holes 433 are formed to face each other on the outer circumferential surface of the light quantity adjusting reflective member 430 . The frame insertion hole 433 is formed in a certain angular range along the upward direction so as not to interfere with the substrate frame 420 when the light quantity adjusting reflective member 430 is rotated left and right.

Accordingly, as shown in FIG. 6 , when the light amount adjusting reflective member 430 is rotated left and right, it is prevented from interfering with the substrate 411 .

A rotation shaft 431 is provided on the upper portion of the light quantity control reflective member 430 . The rotation shaft 431 is coupled to the driving shaft 441 of the reflective member driving unit 440 . The reflective member driving unit 440 is rotated forward and reverse according to the control signal of the control unit 700 and adjusts the rotation direction and the rotation angle of the light quantity control reflective member 430 .

List in advance the amount of light irradiated to each pair of ginseng (A) according to the rotation angle of the light quantity control reflection member 430, and the control unit 700 satisfies the PPFD suitable for the growth rate of the pair of ginseng (A). The reflective member driving unit 440 is driven so that a possible amount of light is supplied.

For example, as shown in FIG. 6 , when a greater amount of light needs to be supplied to the first ginseng (A1) among the first ginseng (A1) and the second ginseng (A2) accommodated in the ginseng cultivation tank 100, the control unit ( 700 drives the reflective member driving unit 440 to rotate the light amount adjusting reflective member 430 clockwise. As a result, the light irradiated from the light emitting member 410 is reflected on the inner surface of the light quantity control reflective member 430 and is blocked from being supplied to the second ginseng A2 and supplied to the first ginseng A1. Accordingly, the amount of light supplied to the second ginseng A2 is relatively decreased and the amount of light supplied to the first ginseng A1 is increased.

Meanwhile, FIG. 7 is an exemplary view illustrating a modified example of the lighting unit 400a. In the above-described lighting unit 400, a plurality of light emitting members 410 in the form of LED elements are disposed to correspond to the intervals of the ginseng cultivation tank 100 along the longitudinal direction of the substrate frame 420, and each light emitting member 410 is provided with a plurality of light emitting members 410. It was a form in which the hemispherical light quantity control reflective member 430 was coupled.

On the other hand, the lighting unit 400a according to the modified example is provided with a bar-shaped LED lamp in which the light emitting member 410a has a predetermined length, and is provided on both sides of the light emitting member 410a to correspond to the spacing of the ginseng cultivation tank 100 A plurality of pairs of light quantity control reflectors 450 and 450a are disposed.

A pair of light quantity control reflecting plates 450 and 450a are provided in a plate shape having a predetermined area, and are provided to be rotatable up and down by a reflective member driving unit (not shown) coupled to each rotation shaft 451 and have a reflection angle. is regulated As a result, the light quantity control reflectors 450 and 450a allow or reflect the movement of the light L toward the first ginseng A1 or the second ginseng A2, and the amount of light supplied to the pair of ginseng A1 and A2 make it equal

On the other hand, as shown in FIG. 6 , a camera 500 for photographing a pair of ginseng A1 and A2 planted in each ginseng cultivation tank 100 is provided in front of each ginseng cultivation tank 100 . The camera 500 is preferably provided as an infrared camera, but may be provided in another type depending on the case.

The ginseng size determination unit 600 analyzes the photographed image of the first ginseng (A1) and the photographed image of the second ginseng (A2) taken by the camera 500, respectively, and the first ginseng (A1) and the second ginseng (A2) ) to determine the size of The ginseng size determination unit 600 detects the size of ginseng from the image processed by the image processing unit 610 and the image processing unit 610 for processing the photographed image taken by the camera 500 as shown in FIG. It includes a size detection unit 620 and a light quantity determination unit 630 that determines the PPFD suitable for the size of ginseng detected by the size detection unit 620 .

(a) of Figure 8 is an exemplary view showing the ginseng (A) planted in the ginseng cultivation tank 100, Figure 8 (b) is the ginseng of Figure 8 (a) is photographed by the camera 500 It is an image of ginseng.

The image processing unit 610 determines the boundary line L by finding a boundary value between the ginseng and the background in the ginseng image shown in FIG. 8(b) . At this time, when the camera 500 is an infrared camera, the root of ginseng A does not transmit light, so the boundary line L of ginseng can be determined using this.

The size detection unit 620 sets the upper one side of the photographed image as the origin (O), and sets the coordinate values of each value (a, b, c, d, e, f, g, h, i) on the boundary line (L). In comparison, the size of the ginseng is determined by detecting the horizontal size and vertical length (b) of each part of the ginseng (A).

The size detection unit 620 measures the width of the ginseng along the height direction, but finds an area in which the empty space inside is less than a certain ratio (for example, 30%). In (b) of FIG. 8 , it is determined that a1 has no empty space, a2 has 20% empty space, and a3 has 30% empty space.

A lot of empty space means a lot of fine roots, and when measuring the length of ginseng, set a3, the point where the empty space is 30%, as the lower point of the root.

Thereby, the total length (b) of the ginseng (A) is from the origin to the point a3.

Here, the reference % of the empty space for setting the length may be variously set as well as 30%.

Meanwhile, the size detection unit 620 calculates an actual width excluding the empty space among the horizontal widths of the root region in which the empty space is less than 30%. Comparing a2 with a1 in (b) of FIG. 8 , although a2 is longer, there are more empty spaces (20%) than a1. Accordingly, when the empty space portion of a2 is subtracted and the width is compared with a1 again, it is determined that the width of a1 is the thickest.

The size detection unit 620 roughly calculates the root volume of ginseng by multiplying the thickest width (a1) in ginseng, the measured length (b), and a predetermined coefficient. The predetermined coefficient may be set to an experimentally suitable value.

The light amount determination unit 630 finds a PPFD value suitable for this based on the root volume of the ginseng (A) calculated by the size detection unit 620 . A PPFD table 631 corresponding to the growth of each root volume of ginseng is stored in the light quantity determination unit 630 . The light quantity determination unit 630 finds a PPFD value corresponding to the root volume of ginseng (A) calculated in the PPFD table 631 and transmits it to the control unit 700 .

The light amount determination process of the ginseng size determination unit 600 is performed for all ginseng planted in the plurality of ginseng cultivation tanks 100 .

The control unit 700 is positioned to correspond to the upper portion of the ginseng cultivation tank 100 in which each ginseng A is planted, based on the PPFD value corresponding to the growth rate of each ginseng A transmitted from the light amount determination unit 630 . Adjusts the rotation angle of the light amount control reflective member (430). Thereby, the amount of light suitable for the growth rate of the ginseng (A) is supplied. That is, the light irradiation amount is increased in fast-growing ginseng to control the PPFD to rise, and conversely, the light irradiation amount is decreased in the slow-growing ginseng so that the light irradiation amount is reflected or dispersed so that the PPFD does not rise excessively.

On the other hand, as shown in Figure 2, the ginseng hydroponics system 1 of the present invention includes a plurality of temperature control water tanks 200, 200a, 200b, 200c, and each temperature control water tank 200, 200a, 200b, 200c, ) includes a plurality of ginseng cultivation tanks (100, 100a, 100b, 100c, 100d) accommodated in the .
