The present invention relates to a plant cultivation apparatus capable of creating an optimized environment for plant growth by creating an atmosphere corresponding to the natural environment within a designated area.

Various kinds of plants are artificially grown for the purpose of edible, ornamental or experimental purposes. Such artificial cultivation is carried out indoors as well as indoors, and in the case of indoor artificial cultivation, various devices are configured to grow a plant to be grown in the same environment as nature.

FIG. 1 is a schematic view showing a conventional artificial cultivation of a plant, and will be described with reference to FIG.

In order to grow plants, one or more shelf fields 10 are provided in a given space H. At this time, a multi-layer shelf may be formed in the shelf 10 so that the shelf can support the container 20 in which the plant 30 is planted. On the other hand, the lower portion of the shelf is provided with a lighting lamp 310 for illuminating the container 20 located on the lower floor.

As described above, the lamp 310 is a means for providing light for photosynthesis of the plant 30, and typically, a resistance lamp such as an incandescent lamp or a discharge lamp such as a fluorescent lamp is used, among which a fluorescent lamp having a relatively low power consumption is used. Widely used. The lamp 310 is turned on and off in a cycle corresponding to the sunrise and sunset cycles of the natural world, so that the plant 30 can proceed to the stable photosynthesis and breathing activity. On the other hand, artificial cultivation, as shown, for the purpose of a large number of plant cultivation, a plurality of lamps 310 is installed in one of the shelves 10, the lamp 310 is collectively controlled. Accordingly, the shelf 10 may be provided with operation panels 50, 50 ′, 50 ″ for collectively controlling the lighting and turning off of the lamp 310.

As described above, in order to cultivate the plant 30 in a room, it is necessary to provide a certain environmental condition, and installation and operation of various devices are required for this purpose. However, these devices require constant power consumption, and this power consumption increases the cost of growing the plant (30), thus reducing the final revenue generated by plant (30) cultivation.

In addition, the cultivation space of the plant 30 is limited to the shelf 10, while the humidifier 60, the air conditioner 70, the ventilator 80, and the like, which form a growth environment of the plant 30, have a space (H). Since power must be consumed to create an environment for the whole, the conventional way of growing plants 30 indoors has been very inefficient and inefficient.

In order to solve this problem, plant growers have been studied to reduce the running time of the devices. However, the shortening of the driving time of the devices was a cause of deteriorating the growth environment of the plant 30, which causes a deterioration of the quality of the plant 30 and a high rate of defects, and thus, a problem in which the economic loss increases.

The lighting unit 300 supplies light so that the plant to be cultivated may perform photosynthetic activity, and various light emitting means such as a resistance lamp, a discharge lamp, and an LED may be applied. By the way, the lighting unit 300 according to the present invention should repeat the flashing at a specified frequency, and this flashing period adjustment is preferable because the power consumption is relatively large, it is preferable to apply the LED as an embodiment for the lighting unit 300.

The lighting unit 300 according to the present invention reduces the amount of power consumed for driving by lowering the brightness, and the loss received by the plant due to the reduced brightness is compensated by adjusting the flashing cycle of the lamp, so that the power consumption for artificial cultivation of the plant It can save and maintain or improve the quality of the plant.

The lighting unit 300 for this purpose is to control the brightness adjustment and the flashing cycle of the lamp 310, it can be set by selecting the brightness and the flashing cycle of the lamp 310 according to the variety of plants.

The lighting unit 300 according to the present invention includes a lamp 310 installed in the cultivation space 101, a PWM waveform generator 320 for generating a pulse signal, and a DC power supply DC. And a constant current controller 330 (constant current control driver) for providing electricity to the lamp 310 according to the pulse signal of the PWM waveform generator 320 to switch the lamp 310 to have a flashing period corresponding to the pulse signal.

Here, the lamp 310 may be applied to the LED (light emitting diode) lamp that can be flashed in the corresponding flashing cycle in response to the electricity supplied by the constant current controller 330. The lamp 310 is preferably disposed directly above the cultivation bed 200 in order to effectively illuminate the plant of the cultivation bed 200, for this purpose is to be installed on the bottom of the shelf 110 supporting the cultivation bed 200 Could be. However, the present invention is not limited thereto, and may be directly fixed to the inner wall of the cultivation space 101 or may be fixed through a hanger (not shown) protruding from the inner wall.

The grower may control the flashing cycle of the lamp 310 by controlling the controller 800 by manipulating the input / output unit 700 individually configured in the plant cultivation apparatus. However, in addition to the grower may be connected to the control unit 800 using the central control unit (C1), computer (C2), mobile communication terminal (C3) and the like to communicate with the control unit 800 via a communication network, through this control unit 800 ) Can directly control the operation of the lamp 310.

Figure 5 is a graph showing the bio weight of the plant as a result of the plant cultivation experiment using the lighting unit according to the present invention, Figure 6 is a graph showing the building of the plant as a result of cultivation experiment of the plant using the lighting unit according to the present invention, Figure 7 Is a graph showing the number of leaves of the plant as a result of the cultivation experiment of the plant using the lighting unit according to the present invention, will be described with reference to this.

Using the lighting unit 300 according to the present invention, the brightness of the lamp 310 irradiated onto the plant was adjusted, and the blinking period of the lamp 310 was adjusted to confirm the final quality of the specific plant.

Here, varieties of plants were made from blue lettuce lettuce (Asian seedlings).

The lamp 310 was a 12W LED lamp, and the pulse signal range of the PWM waveform generator 320 was set to a minimum resolution of 25 MHz, a maximum resolution of 97.65 KHz, and a maximum interval of 0.6710 sec.

The lighting cycle of the lamp 310 was set to 16 hours / day, the growth environment management of the plant 30 was 450ppm carbon dioxide, temperature 20.5 ℃, humidity was 68%, average management was carried out.

로 측정되는 광량이다.On the other hand, after the plant is planted in the cultivation bed (200) until the root sticking period of 4 days, the brightness ratio (Duty ratio) of the lamp 310, the environmental conditions of the experimental group is maintained at 100%, the flashing period is the same 400 ㎲ Let it. Here, 100% brightness of the lamp 310 is at a distance of 30cm away from the lamp 310

The amount of light measured by.

In this experiment, four experimental groups were applied with different environmental conditions.

The first experimental group (blue) applied a flashing cycle of 200 Hz and a relative brightness of 50%.

The second experimental group (red) applied a flashing cycle of 200 Hz and a relative brightness of 100%.

The third experimental group (green) applied a flashing cycle of 400 Hz and a relative brightness of 50%.

The fourth experimental group (purple) applied a flashing cycle of 400 Hz and a relative brightness of 100%.

As shown in FIG. 5, the bioweight of the plant was not large in each experimental group until 12 days after planting, but after 19 days of planting, the difference occurred according to environmental conditions, and the difference in each experimental group was prominent at 26 days. .

In summary, in the first and second experimental groups and the second and third experimental groups having the same flashing cycle, the biomass weights of the second and fourth experimental groups with large relative brightness were large. On the other hand, in the first and third experimental groups and the second and fourth experimental groups having the same relative brightness, the biomass weights of the first and second experimental groups having a small flashing period were large. As a result, it is confirmed that even if the relative brightness is lowered, the bio weight of the plant can be compensated by adjusting the blinking period of the lamp 310.

On the other hand, the bio weights of the second and third experimental groups having different conditions of relative brightness and flashing period were found to be highly significant, which is determined by adjusting the relative brightness and the flashing period of illumination of the plant, thereby improving the quality of the plant. It will be evidence of improvement.

As can be seen from Figure 6, in the building of the plant, the difference of each experimental group is not large until 12 days after planting, the difference occurred according to environmental conditions after 19 days after planting, the difference of each experimental group was noticeable on 26 days . On the other hand, in the first and third experimental groups and the second and fourth experimental groups having the same relative brightness, the building weights of the first and second experimental groups with small flashing periods were large. As a result, it is confirmed that the building weight of the plant can be compensated by adjusting the blinking period of the lamp 310 even though the relative brightness is lowered.

On the other hand, in the buildings of the second experimental group and the third experimental group having different conditions of the relative brightness and the flashing period, the significance was found to be high, which was determined by adjusting the relative brightness and the flashing period of the lighting for the plant. It will be evidence of improvement.

As shown in FIG. 7, the number of leaves of plants was an additional 0.25 in the second experimental group from 12 days after planting, and the number of leaves in the second experimental group was 1.5 more than in the fourth experimental group from 26 days after planting. . In addition, when viewed as a whole, it is confirmed that the leaves and the patterns of the first to fourth experimental groups are similar to those of the bioweight and the building weight. After all, by adjusting the relative brightness and blinking period of the lighting for the plant, it will be a basis for showing that the quality of the plant can be improved.

Through the above experimental results, it was confirmed that when the brightness of the lamp 310 is lowered, the quality of the plant 30 is somewhat reduced. Of course, the difference in quality may not be significant according to the degree of adjustment of the brightness, but it is clear that the lower the brightness affects the plant.

However, it was confirmed through this experiment that the damage caused to the plants by adjusting the brightness is compensated by adjusting the blinking period of the lamp 310. This provides the illumination cycle (flashing cycle) according to the photosynthesis cycle of the plant to ensure that the lamp 310 blinks only a minimum, so that the plant can perform sufficient photosynthetic activity while the stress due to the continuous blinking of the lamp 310 Is assumed to be a minimized effect.

On the other hand, as shown in Table 1, through the brightness adjustment of the lamp 310 it was possible to obtain the following power savings. Here, the voltage is 24V.

Brightness level (%) Current consumption (A) Power Consumption (W) 10 0.022 0.528 20 0.045 1.080 30 0.068 1.632 40 0.092 2.208 50 0.115 2.760 60 0.138 3.312 70 0.163 3.912 80 0.188 4.512 90 0.214 5.136 100 0.245 5.880

As can be seen, when the brightness is lowered from 100% to 50%, the power consumption was reduced from 5.880W to 2.760W. On the other hand, adjustment of the flashing period did not cause changes in the current consumption and the power consumption.

As a result, as shown in the previous test results, it was found that the difference between the first and fourth experimental groups in which the flickering period was adjusted was not large, and the power consumption could be reduced instead of lowering the brightness in the plant varieties. It has been demonstrated that the lighting unit 300 according to the present invention can reduce power consumption and maintain or improve plant quality. Therefore, according to the varieties of plants according to the growth stage by checking the optimized lighting brightness and flashing cycle compared to the power consumption, and if the control of the driving of the lighting unit 300 based on this, the power consumption is reduced and the plant yield can be increased You can expect.

The cooling unit 400 is a device for forcibly lowering the ambient temperature by compressing, condensing, and evaporating a refrigerant gas such as NH ₃ , freon, and the like, which is applied to a plant cultivation apparatus according to the present invention, according to a control signal of the controller 800. It performs a function of forcibly lowering the temperature of the growing space 101. To this end, the cooling unit 400 includes a compressor 410 forcibly compressing the refrigerant gas, a condenser 420 for condensing the compressed refrigerant gas, and an evaporator 430 for evaporating the condensed refrigerant gas. do. In particular, since the evaporator 430 is disposed adjacent to the cultivation space 101 to forcibly discharge cold air through a plurality of cold air discharge holes 104 formed in the cultivation space 101, the air in the cultivation space 101 by using the cold air It can be cooled, through which the temperature of the cultivation space 101 can be forcibly lowered. The cooling unit 400 is a known or common cooling technology applied to a refrigerator or an air conditioner, and the like, and a detailed description of the hardware structure of the cooling unit 400 is omitted here.

The heating unit 500 includes a controller 510 which wires an electric resistance wire (heat wire; not shown) such as a nichrome wire in the cultivation space 101, and controls an electric supply to the electric resistance wire. In this case, the controller 510 may be applied with a material such as a variable resistor to control the supply of electricity to the electric resistance wire according to the control signal of the controller 800, and thus the heating unit 500 controls the controller 800. In response to a signal, the air in the cultivation space 101 is heated to forcibly increase the temperature.

Heat generated from the electrical resistance wire may be transmitted to the plant by a simple radiation method, or may be transmitted to the plant by forcibly generating airflow by means such as a fan (not shown).

The sensor unit 600 detects an environment of the cultivation space 101 and transmits the detected collection information to the control unit 800. The collection information includes one selected from the temperature, humidity, or carbon dioxide amount of the cultivation space 101. The above may be included. To this end, the sensor unit 600 may include a temperature sensor, a humidity sensor, a carbon dioxide sensor, and the like. Here, in the embodiments of the temperature sensor, the humidity sensor, and the carbon dioxide sensor according to the present invention, a conventional sensor manufactured to detect a corresponding object may be applied.

For reference, since each sensor (temperature sensor, humidity sensor, carbon dioxide sensor, etc.) constituting the sensor unit 600 generates and transmits a signal of a general analog type, a separate relay means before the control unit 800 receives it. The signal may be converted into collection information that may be processed by the controller 800 and then transferred to the controller 800.

The nutrient solution supply unit 900 is a nutrient solution tank 910, the nutrient solution is stored, and the nutrient solution of the nutrient solution tank 910, as shown in Figure 9 (a front view schematically showing the appearance of the cultivation box according to the present invention) Consists of a nutrient solution pump 920 for pumping, and the nutrient solution tank 910 and the cultivation bed 200 to circulate the nutrient solution tank 910 and the cultivation bed 200, the pipe 930, 940, 950 do.

The nutrient solution tank 910 may be disposed in the first accommodating space 102 of the cultivation box 100, and it may be desirable to form a structure that can be easily inserted and removed so that the grower can easily fill the nutrient solution.

The nutrient solution pump 920 pumps the nutrient solution stored in the nutrient solution tank 910 and transfers it to the cultivation bed 200 located at the top of the cultivation chamber 100, and the first pipe 930 is the cultivation bed 200. It is connected to the inlet pipe 211 in the tank (210, 210 ') of. Here, the nutrient solution pump 920 is operationally controlled by a control signal transmitted from the controller 800, through which the flow rate for the nutrient solution can be adjusted.

Subsequently, the growing bed shown in Fig. 8 (a) and the growing bed shown in Fig. 8 (b) are alternately arranged up and down, and the second pipe 940 is the inflow pipe 211 and the outflow pipe of each of the growing beds. Connected to the 212 and the cultivation bed is arranged up and down. As a result, the nutrient solution of the cultivation bed 200 located at the top thereof is freely dropped along the second pipe 940 connected to the outlet pipe 212 and flows into the corresponding inlet pipe of the cultivation bed located directly below. In this case, the amount of dissolved oxygen may increase due to the bubbles generated during free fall, thereby maintaining the freshness of the nutrient solution at all times even without a separate air injection.

The nutrient solution injected into the tank of the cultivation bed disposed in a plurality of layers in a manner of freely falling from the upper layer to the lower layer through the second pipe 940 is finally returned to the nutrient solution tank 910 through the third pipe 950. Of course, the returned nutrient solution is pumped by the nutrient solution pump 920 and transferred to the cultivation bed 200 located at the top through the first pipe 930, and the above-described process is repeated.
