Description

Plant factory system

The present invention relates to a plant factory system.

Plant factory means a plant that can produce a large amount of plants by artificially creating environmental conditions for plant growth in a closed space and controlling the growth rate of plants. In relation to plant plants, Joseph W. Campbell et al. Proposed the concept of "automatic food plant production" in US Patent Publication No. 4,068,405 in 1978. They built tray-type plant cultivation on a continuous conveyor belt, installed artificial light, and periodically moved the conveyor. In addition, the nutrient solution supply network was installed so that the nutrient solution can be supplied centrally, and the temperature, humidity, and carbon dioxide concentration can be controlled for plant growth indoors.

This invention was a technically important development in that it proposed a mass production technology of a plant factory. However, due to the low precision of environmental control, high heating and cooling costs, and high installation and operating costs of artificial light sources, the commercialization was very low.

In recent years, an invention related to a plant factory using LED having excellent efficiency as compared to a conventional fluorescent lamp as an artificial light source has been reported. Korean Patent Laid-Open Publication No. 10-2004-0010426 (Dye plant with LED light source and its device) in the cultivation of pigment plants in the closed space to increase the production efficiency in a short space and to be grown in a short time ( LED, Light Emitting Diode) As a plant factory, LED lamps with far infrared light 730 nm, red light 660 nm, and blue light 450 nm are used as light sources. In addition, an ultraviolet sterilizer and an ozone sterilizer of the culture medium were configured, and the dissolved oxygen supply device was used to supply the dissolved oxygen of the culture solution. Cultivation uses NFT (Nutrient Film Technique) and spray hydroponic systems.

In addition, in order to maximize the space for plant cultivation by minimizing the space occupancy in the plant factory, a plant cultivation lighting apparatus for inserting a plurality of LED modules into the floodlight panel, and manufacturing in a slim panel form is disclosed in Korea Patent Publication No. It was reported in 10-2011-0013164. This reduces the space of the lighting device, and features a simple configuration. In recent years, many technologies are mainly focused on LEDs and diversifying light sources to promote plant growth. However, these technologies can be viewed as a high cost structure because the installation of a lot of expensive LED. The closed plant factory is a method that induces the growth of plants with only artificial light without sunlight in the existing closed reinforced concrete or steel structured building, so it is easy to control the environment of the building, but it has the disadvantage of expensive facility cost. It is developing into a building plant factory using

The solar combined type is a fusion of the technical concept of the existing glass greenhouse and the plant factory, and has the technical characteristics of lighting using artificial lighting and sunlight at the same time. Conventional glass greenhouses are made of transparent glass, so the solar transmittance is about 90%. The disadvantages of glass greenhouses are that they do not have good thermal insulation, so they have high indoor and heating energy costs in summer or winter. In addition, there is a problem that can not use the space efficiently because it is difficult to multilayer. The advantage is that daylight mainly uses sunlight and artificial lighting as a supplement, and at night only artificial light can reduce the installation cost of the light source. Conventional solar photovoltaic panels are mostly single-story buildings, and thus the space is not effectively utilized, and heating costs are high in winter and cooling costs are high in summer, resulting in high energy costs.

Angle of the beam 140 and the horizontal member 130 on the same plane is the same. As shown in FIG. 5, when the upper surface of the cell unit 100 has a regular hexagonal shape, the angle formed with the horizontal member 130 on the same plane is 60 degrees, and the beams 140 are formed around the support zone 110. The angle is also 60 degrees.

In addition, such a cell unit 100 is structurally stabilized by combining each honeycomb structural element with a dry-based beam 140 centered on the support zone 110 disposed in the center. Cell portion 100 made of a multi-layer is made of a precast prestressed concrete (PCaPC) structure type to reduce the weight and quality uniformity, shorten the construction period. In addition, by placing the support zone 110 in the center can minimize the number of the support zone 110 and the beam 140 to reduce the construction cost.

The cell unit 100 described above is a structure having a minimum of structural elements, the support zone 110, a plurality of vertical members 120, a plurality of horizontal members 130, and a plurality of beams 140. It has a ring structure connected with). This structure is different from the conventional structure having a simple cubic structure, despite the movement of the sun during the day, it facilitates the inflow of sunlight to maintain a high amount of solar radiation inside the cell portion (100). To this end, in the case of rural areas, the cell unit 100 is installed high, and in the case of the city, the cell 100 unit is installed wide.

In addition, the plane surrounded by the support zone 110, the horizontal member 130, the beam 140 is formed of concrete, the beam 140 is applied to the concrete so that the tensile stress is not applied to the concrete. In this way, tension is applied to the cell portion 100 to form an integrated structure.

The shape of the polygons connecting the top of the vertical member 120, and the shape of the polygons connecting the bottom of the vertical member 120 is the same as the shape of the polygon formed on the top or bottom of the support zone 110, and may be a regular hexagonal shape. have. The envelope member 115 is formed of multiple plastic sheets (or glass) through which light passes well, and a space is formed between the plastic sheets. For example, the outer shell member 115 may be formed of a double window (or double skin) formed of a plastic sheet, as shown in Figure 3, by circulating the air 155 to the outer shell member 115 The temperature in the cell unit 100 is kept constant, and provides an optimal environment for crop growth. Specifically, the outer shell 115 is a plurality of outer shell member 115 formed of a plastic sheet excellent in transparency and elasticity, such as PMMA (acrylic), polycarbonate is arranged at a predetermined interval, the air conditioning facility between the outer shell member 115 By circulating the air flowing from the air, it is possible to appropriately control the inflow and outflow of thermal energy into the indoor and outdoor to reduce the heating and cooling costs. In addition, the shell member 115 may be a plurality of glass (eg, double glass). In this case, the glass facing the outside may maximize the inflow of sunlight using a material having excellent permeability, and the glass facing the inside may maximize the thermal insulation effect by maximizing the thermal insulation performance. In such a case, when the glass is double glass, in the double glass, the glass facing the outside is more permeable than the glass facing the inside, and the glass facing the inside is more heat insulating than the glass facing the outside. In addition, the shell member 115 may optimize the temperature environment in the cell unit 100 by using the difference in the thermal environment for each season. That is, if the wind directly applied to the crop is a barrier to crop growth due to the dry environment, double windows (115a, 115b) can prevent such a barrier. In other words, by circulating air in the outer shell formed of a plastic sheet of a double structure it can block the outflow and inflow of thermal energy in the plant factory. That is, in winter, circulating air or waste heat introduced into the interior can reduce heat energy flowing out to the outside, and in summer, circulate cold air supplied through the air conditioning facility in the same way to heat transfer through the plastic skin from the outside. By reducing the cooling energy of the room can be reduced. In summary, circulating the air flowing from the air conditioning facility between the shell formed of the plastic sheet of the dual structure to properly control the flow of heat energy into the room and the outside, thereby greatly reducing the heating and cooling costs in the plant factory.

Natural light is possible through such an outer shell member 115, and the light insufficient by natural light can be supplemented with an illumination lamp 221 (fluorescent lamp or LED).

It may further include a water supply means for supplying water to the upper end of the outer shell 115 to flow water down to the lower end of the outer shell 115 along the outer surface of the outer shell 115. In this case, the guide 117 is disposed outside the outer plate (see 115b in FIG. 4A) and is provided at the lower end of the outer skin 115 to guide water downward from the water supply means. It may further include a drip tray receiving the flow of water guided by). The drip tray is for recovering water flowing through the outer skin 115 when the outer skin 115 overheated in the summer with water. As such, the temperature of the shell member 115 may be reduced by flowing water in the summer portion of the outer shell member 115 having a double structure. In addition to the direct contact with water on the surface of the outer shell member 115 in the summer, there is an effect that can directly take heat from the heated outer shell member 115, as well as the water generated in the process of evaporating water from the surface of the outer shell member 115 The heat of evaporation (endothermic) has the effect of taking heat away from the shell member 115. In addition, as shown in Figure 4b, because the guide 117 extends downward, the water supplied from the water supply means is guided below the guide 117 when water is supplied from the top of the outer shell portion 115 It will not flow to either side.

The guide diaphragm 116b may be provided to distinguish the areas of the outer plate 115a and the inner plate 115b, respectively.

In addition, the outer skin part 115 is disposed below the outer skin part 115 and has a first air hole (not shown) and a second air hole 116l on the outer side and the inner side of the outer skin part 115, respectively. 116c, and an agent having a third air hole (not shown) and a fourth air hole 116m, which are disposed from the lower side to the upper side and the upper side of the outer skin part 115, respectively, on the outer and inner sides of the outer skin part 115, respectively. 2 air pipes 116d. When the temperature sensed by the temperature sensor 116h is higher than the predetermined temperature, cooling air having a temperature lower than the predetermined temperature is introduced into the third air hole, and the cooling air is supplied to the outer plate 116a through the fourth air hole 116m. Flows between the inner plate 116b and is discharged to the outside of the outer skin 115 through the first air hole through the second air hole 116l, and the temperature detected by the temperature sensor 116h is lower than the predetermined temperature. The heating air having a temperature higher than a predetermined temperature is introduced into the first air hole, and the heated air flows between the outer plate 116a and the inner plate 116b through the second air hole, and opens the fourth air hole 116m. Through the third air hole is discharged to the outside of the outer skin 115. Here, predetermined temperature is the same as the setting reference value mentioned later. As such, when the temperature in the outer skin 115 is higher or lower than the predetermined temperature, the temperature may be controlled to be properly maintained.

The first air pipe 116c is connected to the first valve 116e, and the second air pipe 116d is connected to the second valve 116f. The first valve 116e and the second valve 116f may be controlled by the temperature sensor 116h described later, and the first air pipe 116c is controlled by the first valve 116e and the second valve 116f. ) And the flow rate of the air flowing into the second air pipe 116d is changed. In this way, the flow of air in the outer skin 115 can be controlled through the first air pipe 116c and the second air pipe 116d, so that the temperature in the outer skin 115 can be properly maintained.

In addition, the outer skin 115 is disposed on the flow meter 116g and the inner plate 115b for measuring the flow rate of air, and senses the temperature of the air flowing between the outer plate 115a and the inner plate 115b and exceeds the set reference value.

The installation position and the number of the fans 116j are not limited. Through the fan 116j, the air inside the cell unit can be quickly discharged to the outside of the cell unit. The set reference value can be a specific temperature value.

The outer skin 115 is for controlling the indoor temperature of the plant factory, based on the air-circulating outer shell structure. In winter, since the outside temperature is lower than the inside of the plant factory, the heat of the inside may be rapidly leaked through the outer skin 115. In addition, in the summer, since the outside temperature is higher than the inside of the plant factory, the heat of the outside is easily transmitted to the room through the outer skin 115. As described above, the present invention is to reduce the entry of heat according to the change of the season, when the outside temperature is low (for example, in winter), the hot air through the first air pipe 116c and the outer plate (115b) It is introduced between the inner plate (115a). These flow through the second air pipe (116d) and is discharged to the outside through the second air pipe (116d) installed on the upper again. In this process, the air temperature between the outer plate 116a and the inner plate 116b rises and the heat transfer to the outside becomes slow. The first air pipe 116c and the second air pipe 116d allow the introduced air to effectively flow between the outer plate 116a and the inner plate 116b. When the outside temperature is high (for example, in summer), cold air flows between the outer plate 115b and the inner plate 115a through the second air tube 116d. They flow through the second air pipe 116d and are discharged to the outside through the first air pipe 116c installed at the lower portion again. In this process, the air temperature between the outer plate 115b and the inner plate 115a is reduced to reduce heat transfer to the room. The inflow and outflow of air between the outer plate 115b and the inner plate 115a is controlled by the temperature sensor 116h provided in the inner plate 115a. That is, when the temperature of the outer skin 115 is higher or lower than the target value (reference value), the air flow rate of the flow meter 116i is increased to appropriately control the temperature of the outer skin 115. The compressor 116i may be connected to the flow meter 116g to adjust the air pressure. Since the compressor 116i is connected to the air conditioner 116k, the temperature-controlled air may be smoothly supplied to the outer skin. The air flowing between the outer plate 116a and the inner plate 116b by the temperature control is discharged to the outside of the outer shell portion 115 or recovered into the inside of the cell portion, so that the first air tube 116c or the second air tube 116d is discharged. Can be recycled for inflow.

The present invention relates to an outer shell structure for controlling the heat transfer of the outer shell to maintain the temperature in the plant factory, the air circulation type double circulating air between the plastic plate (eg polycarbonate) of a slow heat transfer It has an outer shell structure. It is advantageous to enlarge the area compared to the existing plate glass, and there is a side effect of reducing the heat transfer by reducing the area of aluminum as an example of a conventional metal frame (frame). In addition, the temperature is controlled between the outer plate 115a and the inner plate 115b to circulate the air to reduce the heat transfer by controlling the temperature of the outer plate 115a, the inner plate 115b and the air. For example, if the measurement temperature (temperature of the circulating air and the inner plate 115b) is lower than the target temperature in winter, the flow rate of hot air is increased through the temperature sensor 116h, and the measurement temperature is the target temperature in summer. If it is higher, the flow rate of cold air is increased to effectively control the heat transfer to the room by adjusting the temperature of the air and the outer plate 115a and the inner plate 115b, thereby effectively maintaining the indoor temperature in the plant factory. This has the effect of significantly reducing the cost of heating and cooling to maintain the proper temperature required for plant growth.

6 is a perspective view of a cell unit of a crop cultivation unit having a crop planting unit according to an embodiment of the present invention.

In addition, by rotating the rotating body, it is possible to lower the installation cost of the lighting unit 200, it is possible to obtain a flashing effect even when the lighting lamp 221 is not used. That is, the light can be irradiated when the light is needed according to the constant amount of light required for the crop, and the light is not irradiated when the light is not required for the crop, thereby increasing the efficiency of energy consumption by light irradiation.

In addition, the rotational speed is controlled to adjust the amount of light irradiated to the crop. When the rotational speed of the rotating body is adjusted, the blinking time of the lighting unit 200 is also adjusted, and the light intensity and the amount of light can be controlled by adjusting the number of lighting lamps 221 provided in the lighting unit 200.

In addition, the size of the rotating body and the number of the lighting lamps 221 are also variables of the lighting conditions. As the speed of the rotor is faster, the driving energy consumption of the rotor is greater. Therefore, if the lighting cost is optimized by dividing the lighting cost into the lighting facility cost and the lighting operation cost, the economical efficiency of the lighting cost can be increased.

In addition, the distance from the crop planting unit 300 of the rotating body can also be adjusted. At this time, the rotating body may move up or down with the support zone 110 as an axis. When the rotating body moves upward, the distance from the crop planting part 300 becomes long, and when the rotating body moves downward, the distance from the crop planting part 300 becomes short.

The rotating frame 210 is the center of the rotating body and has a hollow shape. The rotating frame 210 rotates while being fitted to the support base 110 even when rotating.

The rotary blade 220 includes an illumination lamp 221 for irradiating light to crops; A reflection plate mounted on the illumination lamp 221 and reflecting the light emitted from the illumination lamp 221 in the direction of the crop may be installed.

The lighting lamp 221 may be composed of a fluorescent lamp or an LED, or a combination of a fluorescent lamp and an LED.

In the case of the LED, by combining the blue LED and the red LED in various configurations, it is possible to irradiate the essential light of the crop growth.

When the combination of the fluorescent lamp and the LED, it is possible to compensate for the problem of using only a fluorescent lamp that is rapidly reduced in life and increase the use of electricity when flashing, or using only expensive LED installation.

The reflector collects the light irradiated from the lighting lamp 221 to the place where the crop is located.

That is, the reflective plate may be provided with a light-organic reflector in order to ensure the incident angle of the sunlight according to the altitude and movement of the sun to 60 degrees or more. The mineral organic reflector may effectively introduce sunlight into the building part 10.

As a result, more light can be efficiently distributed to the crop. The reflector may be formed of a material having high reflectance such as aluminum, stainless steel, or plastic.

The rotary blade 220 may be further provided with a camera for photographing the crop image when the rotary blade 220 is rotated, and a sensor 222 (see FIG. 7) for detecting temperature, humidity, and quantity of light suitable for crop growth. have. The camera and the sensor 222 may be installed only on one rotary blade 220, and because the crop to monitor the state of the crop when the rotary blade 220 rotates, the crop grower is the crop is grown through the camera and sensor 222 You can monitor the process or the condition of the crop. By installing the camera and sensor 222, the crop grower does not have to check the condition of the crops one by one.
