Description

Vertical aquaponics smart farm system { A vertical aquaponics smart farm system }

The present invention relates to a vertical aquaponics smart farm system that links fish farming (Aquaculture) and plant hydroponics.

Aquaponics is a production method that combines fish farming (aquaculture) and crop hydroponic cultivation (hydroponics). It is a production method that combines agricultural and clean areas due to industrialization, soil pollution due to indiscriminate use of pesticides and gunpowder fertilizers, etc. As problems arise, it is attracting attention as a technology that can produce pesticide-free crops in limited areas.

In general, the aquaponics smart farm system absorbs inorganic substances produced by decomposing organic substances generated during the fish farming process (fish excrement and feed residues generated in the rearing water, etc.) by microorganisms as growth nutrients for cultivated crops. The cultivated crops are composed of a recirculating aquaculture system (RAS) that purifies the supplied breeding water and allows continuous purification of the water quality and growth of the cultivated crops.

To be more specific, the aquaponics smart farm system includes a fish tank, a cultivation tank, a lighting unit, a temperature control unit, a humidity control unit, and a control unit for integrated control thereof.

In other words, the breeding water is transferred from the fish tank to the cultivation tank, providing nutrients necessary for crop growth, and the lighting, temperature control, and humidity control are controlled based on circulation filtration in which the water filtered through the cultivation tank is supplied back to the fish tank. The growth environment necessary for crop growth is provided by the control unit and the control unit for integrated control thereof.

Meanwhile, the recently developed aquaponics smart farm system collects fish breeding environment information and plant cultivation environment information, analyzes the collected information, and provides integrated control that links each control component.

For example, Republic of Korea Patent No. 10-2357239 discloses a device and method for controlling a modular smart farm for aquaponics.

Figure 1 is a diagram illustrating a modular smart farm system for aquaponics according to the prior art, in which a number of components constituting a breeding cultivation device are integrated and managed by a control device through a processing module and a communication module.

In detail, the modular smart farm system according to the prior art is equipped with sensors (S) in the breeding tank, sedimentation tank, aquaculture tank, and drainage tank, and the detection information of each sensor (S) is transmitted to the communication module through the processing module and the control device. is collected in

In addition, the control device analyzes the collected information to control the valve (V) and pump (P), and further includes a neural network and a control unit for this purpose.

In other words, the modular smart farm system for aquaponics according to the prior art analyzes the information received through the sensor (S) and controls the valve (V) and pump (P) based on the analyzed results. Commands are calculated through an artificial neural network, and dedicated software (operating program) and equipment system connection are required for this.

However, the integrated control system through dedicated software and equipment grid connection as described above increases the initial investment cost, which is one of the barriers to entry into the aquaponics smart farm system, and causes difficulties in system maintenance for operators.

More specifically, in the integrated control aquaponics smart farm system, approximately 20% of the facility cost is invested in building an integrated control system through dedicated hardware and software, and it is difficult to respond quickly when a breakdown occurs.

In other words, an integrated control system built through dedicated software and equipment control linkage involves the risk of the entire system stopping when some equipment fails or a program error occurs.

However, when the above situation occurs, operators have difficulty identifying the cause of the error, and in order to resolve this, they have no choice but to install an integrated control system or contact the supplier.

In addition, many software installation or supplier businesses are small-scale, and there is a constant risk of continuous and stable maintenance and repair due to company bankruptcy and programmer turnover.

Ultimately, if a problem occurs due to a hardware or program error in the aquaponics smart farm system operated by an integrated control system, you have no choice but to install the software and contact the supplier, and if the response to the contact is not smooth, The operation of the aquaponics smart farm system becomes impossible.

In addition, due to the inability to operate the system, delivery contracts with other businesses are difficult to complete, resulting in penalties being paid, as well as customer defection due to lack of trust in the aquaponics smart farm system. It causes fatal damage.

The above risks are greater for small-scale aquaponics smart farm system operators, and ultimately, system operators face difficulties in stable operation as they become dependent on software installation and suppliers.

As it flows into the internal space 110 through the part 822, convection occurs downward.

In addition, the conditioned air convected downward as described above is forced to flow by driving the plurality of convection fans 120 provided on one side of each of the water tanks 621 to 626, thereby forming a circular flow of conditioned air.

In this embodiment, the air conditioning pipe 810 is located in the central portion of the ceiling of the growth room 100 and is positioned to discharge conditioned air through the discharge portion 812 formed along the side, but the size of the growth room 100 and Depending on the shape, the quantity of the air conditioning pipes 810 may vary, and while they are located at the uppermost part of the growth room 100, the arrangement form may also vary.

In addition, the convection fan 120 is arranged along the longitudinal direction of the sixth water tank 626 on one side of the lighting control unit 720, as shown enlarged in FIG. 6, and a plurality of convection fans 120 are formed at regular intervals to maintain air flow. By forming it, it is possible to provide an air flow like a natural wind in the crop cultivation space provided by the sixth water tank 626.

The air flow as described above can be formed by a convection fan 120 disposed on each floor, and the convection fan 120 on each floor circulates air according to the cycle set by the lighting control unit 720, as described above. It is controlled to create a flow.

Meanwhile, in this embodiment, the lighting control unit 720 provides a cultivation environment in which day and night change through control of the lighting lamp 740.

Figure 8 shows a diagram for explaining the illuminance control process using the vertical aquaponics smart farm system according to the present invention, and Figure 9 shows an embodiment of the vertical aquaponics smart farm system control table according to the present invention. A drawing showing is shown.

Referring to these drawings, in the aquaponics smart farm system according to the present invention, the inside of the growth room 100 is divided into four control sections as shown in the control table of FIG. 9 through individual control of the lighting means 700. Thus, illuminance control is achieved.

First, the control section shown in the control table is divided into a plurality of sections based on 24 hours. In this embodiment, the first control section is a section for creating the inside of the growth room 100 as the first growth environment at 08:30. The lighting 740 is controlled to maintain the first set illuminance (100%) from 22:00 to 22:00.

The second control section is a buffer section to reduce stress on crops due to rapid changes in lighting and temperature, and the third control section creates the darkest and lowest temperature growth environment among the control sections from 00:30 to 06:00. The lighting 740 is controlled to maintain the second set illuminance (50%) from 22:00 to 00:30 before entering the section.

And, in the above-mentioned third control section, the lighting lamp 740 is turned off from 00:30 to 06:00 to maintain the third set illuminance (0%), and the fourth control section is the first control section. Before entering the control section, the lighting 740 is controlled to maintain the second set illuminance (50%) again from 06:00 to 08:30 in the buffer section.

Meanwhile, the lighting means 700 for which the control range of the lighting lamp 740 is set as described above is individually controlled regardless of the control situation of the system configuration of the water circulation system or the system configuration of the air circulation system.

In detail, when the vertical aquaponics smart farm system according to the present invention is turned on, first, the lighting timer 722 is synchronized with the current time.

That is, in the lighting means 700 according to the present invention, the lighting 740 is operated at an illuminance set by the control section divided by the lighting control unit 720 and the operation time of the lighting timer 722, so as to perform initial operation or the entire system. When the system is turned on again after the power is turned off, the lighting timer 722 is synchronized.

And, after the lighting timer 722 is synchronized, the control section corresponding to the current time is checked and illuminance control is performed according to each control section.

Meanwhile, in this embodiment, illuminance control according to each control section can be achieved through controlling the number of lighting lights 740 or adjusting current.

For example, in the case of illuminance control through current control, illuminance can be adjusted by generating signals with different switching frequencies for each set illuminance.

In addition, when illuminance is adjusted by controlling the number of lights, a scattering plate for scattering light is further provided below the lighting lamp 740 along the longitudinal direction of the water tank, and the lighting lamps 740 arranged at regular intervals are further provided along the longitudinal direction of the tank. Illuminance control can be achieved by adjusting the number of lights.

Meanwhile, the control table divided into control sections as described above further includes temperature and humidity ranges for controlling the constant temperature and humidity air conditioning means 800 in addition to controlling the lighting 740.

That is, the control table according to this embodiment has a temperature of 17 to 20°C by air supplied through the constant temperature and humidity air conditioning means 800 in the first control section, which is an environment creation section considering the period from morning to night. Conditioned air is supplied so that the humidity can be adjusted to a range and level of 70 to 80%.

In addition, in the third section, which is an environment creation section considering the night, conditioned air is supplied so that the temperature range of 10 to 13 ° C. and the humidity level of 90 to 97% can be controlled.

In addition, in the present invention, in order to prevent rapid environmental changes between evening and night and night and morning, the second control section and the fourth control section are set as described above, and the temperature range is 13 to 17°C and 70 to 80%. Conditioned air is supplied so that the level of humidity can be controlled.

The second control section, which supplies air conditioned within the above setting range, prevents rapid environmental changes between evening and night, and the fourth control section prevents rapid environmental changes between night and morning.

Meanwhile, Figure 10 shows a diagram showing another embodiment of the control section setting range for lighting control of the vertical aquaponics smart farm system according to the present invention.

In this embodiment of the lighting control, the temperature of the inner space 110 of the growth room 100 is increased by the heat generated from the lighting lamp 740, and the constant temperature and humidity air conditioner 800 produces air with a constant temperature and humidity and a constant flow rate. When provided, temperature changes at sunset and sunrise are realized through sequential lighting control of the lamps.

Hereinafter, for convenience of explanation, the first to sixth water tanks (621622, 623, 624, 625, 626) will be described as the first to sixth floors.

When an LED lamp is applied to the lighting 740, it is assumed that heat of approximately 28 to 29 ℃ is generated on the surface, and when the lighting 740 installed on the 1st to 6th floors are sequentially turned on, the temperature of the internal space 110 gradually rises and maintains a constant temperature.

Also, if the lights 740 are sequentially turned off again after the set time, the temperature gradually decreases, and when they are all turned off, the lowest temperature section can be formed.

That is, in this embodiment, it is turned on sequentially with a time delay set from the 1st floor to the 6th floor to create a temperature atmosphere at sunrise, and is sequentially turned on again with a time delay from the 1st floor to the 6th floor to create a temperature atmosphere at sunset. The lights 740 on each floor are controlled to turn off.

For example, when creating a temperature atmosphere according to the sunrise, the first floor lights up at 6:00, the second floor lights up at 6:30 30 minutes later, and after a 30-minute time delay for each of the 3rd to 6th floors. After 8:30 a.m., when lighting is completed up to the 6th floor, the temperature atmosphere during work hours with all lights 740 turned on is maintained.

In addition, when working hours have elapsed and an atmosphere is created according to the sunset, the lights on the 1st floor are turned off at 22:00, the lights on the 2nd floor are turned off at 22:30 30 minutes later, and the lights are turned off on the 3rd to 6th floors for 30 minutes each. After a delay, the lights are turned off and the night temperature atmosphere is maintained from 24:30 (00:00) when the lights are turned off up to the 6th floor.

Each control section of this embodiment divided as described above is a value derived from the optimal environment for the cultivation of European lettuce grown through the vertical aquaponics smart farm system according to the present invention, and the control section is determined according to the variety of the cultivated crop. The settings can be varied.

On the other hand, in the aquaponics smart farm system according to the conventional integrated control environment, the entire system operation program was newly established when changes in control conditions occurred due to changes in varieties, but in the vertical aquaponics smart farm system according to the present invention, As the system configurations for each system are controlled through individual control units, they can be easily responded to by changing the settings, so the maintenance costs and time of the vertical aquaponics smart farm system operator can be effectively reduced.

In addition, although not shown, the vertical aquaponics smart farm system according to the present invention may be further equipped with a power supply means using a solar panel.

The power supply means can be applied as a Building Integrated Photovoltaic (BIPV) structure forming the upper side of the growth room 100 or the wall of the growth room 100, and the power generated through this is used to supply the feed. Provided with one or more of means (300), oxygen supply and dissolution means (500), calcium carbonate supply means (650), and lighting means (700). Electricity consumption required for operating a vertical aquaponics smart farm can be reduced. .
