The open/closed state of the discharge unit of the feed supply unit 613 can be variably controlled by the control unit 900 . In this case, a reference numerical range may be preset in the control unit 900 .

For example, the control unit 900 opens the discharge unit of the feed supply unit 613 when the water quality measurement value transmitted from the water quality sensor 612 is less than the reference value range to increase the amount of feed discharged, while the water quality sensor When the water quality measurement value transmitted from 612 exceeds the reference value range, the discharge unit of the feed supply unit 613 may be closed to reduce feed discharge. That is, the control unit 900 can variably adjust the amount of feed discharged according to the water quality measurement value transmitted from the water quality sensor 612, so that the water quality of the water W stored in the mooring tank 695 can be maintained constant.

That is, the concentration of nitrate in the water (W) stored in the fish tank 610 should be maintained at 30 to 50 ppm. is reduced, and when the nitrate concentration of water (W) is 30 to 50 ppm, the existing feed supply is maintained.

The carbon dioxide supply unit 960 may include a housing provided in the receiving space 101 and having a space portion formed therein so that solid carbon dioxide is injected therein, and a door portion provided to be opened and closed on one side of the housing. Here, the housing may be provided with a transparent material.

The average concentration of carbon dioxide in air is about 400 ppm. When the external temperature of the housing 100 is between 0 and 17 degrees, the accommodation space 101 having a structure blocked from the outside appropriately controls the rotational speed of the intake part 200 and the exhaust part 300, and in some cases, the temperature By operating the controller 700, the internal temperature of the accommodation space 101 can be appropriately maintained at 20 to 22 degrees. However, when the external temperature of the housing 100 is 5 degrees or less or 18 degrees or more, the temperature is controlled by operating only the temperature control unit 700 while the operation of the intake unit 200 and the exhaust unit 300 is stopped, so the lighting unit In a state in which the lamp 520 of 500 is turned on, the carbon dioxide concentration in the air rapidly decreases due to photosynthesis, so that plants do not grow properly. At this time, the internal carbon dioxide concentration of the accommodation space 101 may be adjusted using solid carbon dioxide to artificially increase the carbon dioxide concentration in the atmosphere.

To this end, the controller 900 may expose solid carbon dioxide to the air by opening the door of the carbon dioxide supply unit 960 when the lamp 520 of the lighting unit 500 is turned on. In this case, solid carbon dioxide is vaporized while coming into contact with air. On the other hand, when the lamp 520 of the above-described lighting unit 500 is turned off, the controller 900 closes the door of the carbon dioxide supply unit 960 to prevent contact between solid carbon dioxide and air. In this case, since vaporization of solid carbon dioxide is prevented, carbon dioxide concentration suitable for photosynthesis can be maintained while minimizing consumption of carbon dioxide.

As a result, the present invention can hydroponically cultivate crops 10 in a cultivation tank arranged in several layers, so that a large amount of crops can be harvested in a narrow space, and from sowing to harvesting of crops 10 in one space. Since it is possible to work in the air, labor can be saved, and water generated in the humidity control process can be reused, so water use can be minimized.

In addition, the present invention can supply high-purity oxygen to the cultivation tank, thereby creating a hydroponic cultivation environment without a separate filtering structure, and maintaining the temperature of the receiving space at a set temperature by adjusting the rotation speed of the intake and exhaust parts. Energy consumption can be reduced, and since the internal temperature of the accommodation space 101 is maintained uniformly, the growth rate of the crops 10 can be kept constant.

In addition, the present invention can maintain the cultivation conditions (temperature, humidity, carbon dioxide, etc.) of the receiving space 101 constant regardless of the external climatic environment, so that crops 10 can be grown in various environments, and the fish tank By monitoring the water temperature and water quality (pH, DO, salinity, ammonia, nitrite, nitrate) in real time, the amount of feed input can be automatically adjusted, and the pH can be automatically adjusted to easily manage the water quality of the fish tank.

In addition, the present invention can increase the efficiency of photosynthesis by appropriately vaporizing solid carbon dioxide according to the photosynthetic time (the time the lamp is turned on) and the non-photosynthetic time (the time the lamp is turned off), and can increase the efficiency of photosynthesis, and when the humidity is low, mist It is possible to automatically maintain proper humidity by spraying, and it is possible to automatically maintain optimal conditions for plant growth by maintaining an appropriate level of nitrate concentration by adjusting the input amount of fish feed.

In addition, the control unit 900 of the present invention receives the internal/external temperature of the housing 100 and appropriately controls the temperature control unit 700, the intake unit 200, and the exhaust unit 300 to control the temperature of the housing 100. The internal temperature can be automatically adjusted, and the internal humidity of the housing 100 can be automatically adjusted by receiving the internal/external humidity of the housing 100 and appropriately controlling the dehumidifier 820 and the mist sprayer 830, By receiving the pH from the water quality sensor 612 and adjusting the operating time of the feed supply unit 613, the feed supply amount can be automatically adjusted, and the carbon dioxide concentration can be automatically adjusted by adjusting the evaporation time of the carbon dioxide supply unit 960. , The pH may be automatically controlled by receiving the pH concentration from the water quality sensor and controlling the calcium carbonate supply unit 696 and the citric acid supply unit 697.

The aquaponics smart farm according to the present invention is a pesticide-free, fertilizer-free 100% natural circulation farming method that can keep the cultivation conditions (temperature, humidity, carbon dioxide, etc.) of the accommodation space constant regardless of the external climatic environment.

In addition, since environmental restrictions for crop cultivation can be reduced, crops can be easily grown in various places, and crops can be grown hydroponically in a growing tank arranged in several layers, so a large amount of crops can be harvested in a small space. Since it is possible to work in one space from sowing to harvesting of crops, it has advantages in reducing labor and maintenance.
