Description

Aeroponic cultivation system capable of real-time measurement of plant live weight}

The present invention is a spray culture system capable of measuring plant live weight in real time. More specifically, the spray culture system, which is one of the hydroponic cultivation methods for crops, is applied and a load cell is used as a means to measure the growth degree in real time. It is about technology that can precisely measure total weight non-destructively.

Methods for analyzing plant growth include measuring height, weight, number and area of leaves, stem length, and length between nodes.

However, these methods require a lot of effort because they have a large margin of error and must rely on manual work for each measurement. In particular, destructive measurement of crops has the disadvantage of making it difficult to measure continuous growth and requiring a large number of repetitions.

Therefore, much research is being conducted on non-destructive methods that can automatically measure real-time growth. As an example, there is a method of measuring diameter, cross-sectional area, and non-large shape using a non-contact infrared sensor, or measuring plant height, diameter, number of leaves, and leaf area using real-time image information. However, these technologies have the problem that many errors occur during the analysis process, which reduces the reliability of plant growth measurements.

Meanwhile, as a non-destructive method of measuring plant growth in real time, methods of measuring live weight in real time during hydroponic cultivation have been proposed.

As an example, the technique proposed by Smolders et al. includes the method of measuring live weight in a phlegmoscope.

In addition, in Korea, a method of measuring live weight in real time using a load cell using the Nutrient Film Technique (Kim Ji-su, Kang Woo-hyun, Ahn Tae-in, Shin Jong-hwa, Son Jeong-ik. 2016. Korean J. Hortic. Sci. Technol. 34(1)77- 83) etc. have been presented.

However, these technologies measure the total weight while the plant's roots are immersed in the nutrient solution and then exclude the weight due to the nutrient solution from the total measurement, so there is a problem of errors occurring in the process of measuring the actual live weight. there is.

The present invention was developed to solve the problems of the prior art as described above, and seeks to propose a method for accurately measuring the growth of plants in real time while applying a spray cultivation method.

In particular, when measuring the live weight of a plant, the total weight including the nutrient solution is measured while the plant's roots are immersed in the nutrient solution, and then the weight due to the nutrient solution is excluded from the total measurement, thereby eliminating errors in the process of measuring the actual plant live weight. We want to solve problems that arise.

The object of the present invention is not limited to the above, and other objects and advantages of the present invention that are not mentioned can be understood by the following description.

In order to solve the above problems, one embodiment of the spray cultivation system according to the present invention includes a bed in which ports are formed to support plants being cultivated in a spray culture while allowing the roots of the plants to grow downward; A mesh network spaced apart from the lower part of the bed and connected to the bed, on which the roots of the plants are seated, supports the weight of the roots, and allows the nutrient solution supplied to the plants to permeate; And it may include a live weight measuring means that is in contact with the bed and measures the live weight of the plant.

Furthermore, it further includes a support frame supporting the bed, and the live weight measuring means includes: a load cell disposed on the support frame and in contact with the bed to measure the weight; and a live weight determination unit that receives the weight measurement value from the load cell and determines the live weight of the plant.

As an example, the live weight determination unit may determine the live weight of the plant by subtracting the weight of the bed and the mesh net from the weight measurement value of the load cell.

Preferably, it may further include a support means connecting the bed and the mesh network to adjust the separation distance between the bed and the mesh network.

As an example, the support means may include: a support bar on one side of which is fixedly connected to the mesh network and on the other side of which the other side can penetrate the bed and be drawn upward from the bed; And it includes a fixing means for fixing the support bar to the bed, and the separation distance between the bed and the mesh network can be adjusted according to the degree of withdrawal of the support bar above the bed.

Furthermore, it is mounted on the support frame, and the bed is seated on the upper part, and further includes a cultivation chamber provided with a growth space where the roots of the plants can grow, and the mesh net is located at the middle of the growth space of the cultivation chamber. It can be.

As an example, the cultivation chamber includes a nutrient solution storage space provided below the mesh network to store the nutrient solution that has passed through the mesh network; And it may include a drain line connected to the nutrient solution storage space to discharge the nutrient solution stored in the nutrient solution storage space.

Preferably, it may further include a drain valve that selectively discharges the nutrient solution stored in the nutrient solution storage space of the cultivation chamber through the drain line.

Going one step further, it may further include a vibration means for shaking the mesh network to remove the nutrient solution present in the mesh network.

As an example, the vibration means includes: a vibration motor disposed on the mesh network to cause vibration; a power supply unit that supplies power to the vibration motor; And it may include a vibration controller that controls the operation of the vibration motor.

According to the present invention, the degree of plant growth can be measured non-invasively and in real time by using a cultivation device equipped with a load cell by applying spray cultivation technology.

In particular, in the present invention, the mesh network minimizes the interference of nutrient solution, which negatively affects the measurement of plant live weight, and obtains a measurement value as close as possible to the actual live weight.

Furthermore, by adjusting the separation distance between the bed supporting the cultivated plant and the mesh network supporting the roots of the cultivated plant according to the growth degree of the cultivated plant, an optimal growth space corresponding to the growth of the plant can be provided.

The present invention proposes a technology that can non-destructively and precisely measure the total weight of crops using a load cell as a means to measure growth in real time while applying the spray cultivation method, which is one of the nutrient solution cultivation methods for crops. .

Figure 1 shows an embodiment of a spray culture system according to the present invention, Figure 2 shows an exploded perspective view of the main components of an embodiment of the spray culture system according to the present invention, and Figures 3 and 4 shows a cut-away cross-sectional view of an embodiment of the spray culture system according to the present invention, and Figure 5 shows a configuration diagram of an embodiment of the live weight measuring means in the spray culture system according to the present invention.

The spray cultivation system 10 according to the present invention includes a bed 110, a mesh network 120, a support means 130, a nutrient solution supply means 140, a live weight measurement means 150, a support frame 160, etc. may include.

The bed 110 can support the growth of the plant 1 grown using a spray cultivation method. A pot 111 may be provided in the bed 110 so that the roots 5 of the cultivated plant 1 can grow downward. The port 111 may be formed as a through hole penetrating the bed 110, and a plurality of ports 111 may be provided on the bed 110 to be spaced apart.

The mesh network 120 may be placed below the bed 110. The mesh network 120 is supported on the bed 110 and the roots 5 of the growing plant 1 are seated thereon, thereby supporting the weight of the roots 5. Additionally, the mesh network 120 may be provided with holes to allow the nutrient solution supplied to the plant 1 to pass through.

While the roots 5 of the plant 1 are supported through the mesh network 120, the nutrient solution supplied to the plant 1 may flow downward and be discharged.

As an example, the mesh network 120 may include a permeable net 121 made of fabric or wire mesh that is permeable to nutrient solution, and a net frame 125 that supports the permeable net 121 while maintaining its shape. Preferably, the permeable network 121 has a permeability level of 60 to 120 mesh, so that the nutrient solution can sufficiently pass through the mesh, but it can be dense enough to prevent plant roots from escaping.

The support means 130 may be connected to the bed 110 and the mesh network 120 so that the mesh network 120 is located below the bed 110.

The support means 130 includes a support bar 131 on one side connected to the lower surface of the outer portion of the bed 110 and on the other side connected to the net 125 of the mesh network 120, and supports the bed 110 through the support bar 131. ) can be maintained on the mesh network 120.

Furthermore, the support bar 131 of the support means 130 can adjust the separation distance between the bed 110 and the mesh network 120. The support means 130 may include a fixing member 135 that fixes the support rod 131.

As an example, the support rod 131 may penetrate the bed 110 and be drawn upwards of the bed 110, and the support rod 131 may be drawn upwardly from the bed 110 according to the length of the bed 110 and the mesh. The separation distance between the networks 120 can be adjusted. In addition, the fixing member 135 can fix the position of the support bar 131 while being supported on the bed 110.

As the fixing member 135, various members capable of holding and fixing the support rod 131, such as a clamp, may be applied.

The bed 110 is fixed by fixing the position of the support bar 131 through the fixing member 135 while the separation distance between the bed 110 and the mesh network 120 is adjusted through the support bar 131 of the support means 130. The separation distance between and the mesh network 120 can be maintained.

As an example, as shown in FIGS. 3 and 4, the bed 110 and the mesh network 120 are supported through the support bar 131 of the support means 130 according to the growth degree of the roots 5 of the cultivated plant 1. By adjusting the distance between the plants, more space is secured for the roots 5 of the plant 1 to grow, and the roots 5 of the cultivated plant 1 can grow more effectively.

For example, in a state where the cultivated plant 1 is relatively low-growing, the separation distance between the bed 110 and the mesh network 120 is adjusted to H1 through the support means 130, so that the plant 1 is grown by the mesh network 120. ) roots (5) can be supported.

As the cultivated plant 1 grows, its roots 5 grow further downward and become abundant, so the space formed by the separation distance H1 between the bed 110 and the mesh network 120 may be insufficient. Therefore, according to the growth state of the cultivated plant (1), the separation distance between the bed (110) and the mesh network (120) is adjusted to H2 through the support means (130) so that the roots (5) of the plant (1) can grow. The roots 5 of the plant 1 can be supported by the mesh network 120 while providing sufficient space.

3 and 4 illustrate that the end of the root 5 of the plant 1 is in contact with the mesh net 120 for convenience of explanation, but in reality, the root 5 of the plant 1 is entirely meshed. It can be supported by being seated on the net 120.

The nutrient solution supply means 140 can supply the nutrient solution to the growing plant (1).

The nutrient solution supply means 140 may include a nutrient solution supply unit 141, a chemical solution supply line 143, a spray nozzle 145, etc.

The nutrient solution supply unit 141 can hold the nutrient solution to be supplied to the growing plant 1 and supply the nutrient solution to the nutrient solution supply line 143. The nutrient solution supply unit 141 may include a nutrient solution storage tank and a pump that supplies the nutrient solution from the nutrient solution storage tank to the nutrient solution supply line 143.

The nutrient solution supply line 143 may be positioned such that one side is connected to the nutrient solution supply unit 141 and the other side extends into the space between the bed 110 and the mesh network 120.

The spray nozzle 145 is disposed in the nutrient solution supply line 143 and can spray the nutrient solution supplied through the nutrient solution supply line 143 toward the plant (1). Preferably, a plurality of spray nozzles 145 may be disposed on the nutrient solution supply line 143 extending into the space between the bed 110 and the mesh network 120.

As an example, the spray nozzle 145 may be a multi-directional spray nozzle capable of spraying the nutrient solution in multiple directions. The spray nozzle 145 can spray the nutrient solution with a particle size of approximately 50 to 100 μm so that the nutrient solution can be evenly supplied to the roots (5) of the growing plants (10).

Preferably, the nutrient solution supply line 143 and the spray nozzle 145 may be arranged so as not to directly contact the roots 5 of the plant 1.

Furthermore, although not shown, the nutrient solution supply means 140 may include a hydraulic gauge and a nutrient solution measuring member that measures the nutrient solution supply flow rate and provides it to the user so that a constant pressure is applied to the spray nozzle 145.

As an example, an inverter may be provided to adjust the pump speed of the nutrient solution supply unit 141 to control the hydraulic pressure of the injection nozzle 145, and a timer may be provided to adjust the nutrient solution injection cycle through the injection nozzle 145. You can.

The support frame 160 can support the bed 110 by floating it.

The live weight measuring means 150 can measure the live weight of a plant 1 being cultivated in contact with the bed 110.

The live weight measuring means 150 may include a load cell 151, a live weight determination unit 153, a live weight information providing unit 156, and a user operation unit 158.

One side of the load cell 151 may be fixedly mounted on the support frame 160 and supported by the support frame 160 . A plurality of load cells 151 may be disposed on the support frame 160. As an example, a plurality of pieces may be arranged to be spaced apart from each other in the longitudinal frame of the support frame 160, or a plurality of pieces may be arranged in each of the longitudinal frame and the width direction frame of the support frame 160.

As an example, the load cell 151 is a single point type, and a standard may be applied in which the sum of the weight measurement limits of each load cell 151 may exceed the sum of the final expected weight of the plants being cultivated by more than 30%.

The load cell 151 may be placed on the support frame 160 at an area in contact with the lower surface of the bed 110. The bed 110 is in contact with the load cell 151 and may not be in direct contact with the support frame 160.

That is, the load cell 151 is located between the support frame 160 and the bed 110, and the other side of the load cell 151 is in contact with the bed 110 and the weight is measured by the pressure pressed by the bed 110. can do.

The weight according to the pressure pressed by the bed 110 may include the weight of the bed 110, the support means 130, the mesh network 120, and the growing plant 1. Here, the weight of the bed 110, the support means 130, and the mesh network 120 can be maintained constant.

The live weight determination unit 153 can determine the live weight of the plant (1).

Since the weight of the bed 110, the support means 130, and the mesh network 120 are kept constant, the live weight determination unit 153 determines the weight of the bed 110 and the support means from the weight measurement value measured by the load cell 151. The live weight of the plant (1) can be determined by subtracting the weight of (130) and the mesh network (120).

The live weight information providing unit 156 may provide live weight information determined by the live weight determining unit 153. The user operation unit 158 may receive a user's operation signal for plant cultivation. For example, the corresponding configurations can be controlled by receiving various user manipulation signals, such as nutrient solution supply control and nutrient solution discharge.

As an example, the panel 155 may be equipped with a display 156 that provides various information such as live weight information, nutrient solution supply amount, and nutrient solution discharge amount of plants being cultivated, and each switch 158 that receives a manipulation signal from the user.

In this way, in the present invention, while supporting the cultivated plant through the bed 110 and the mesh network 120, accurate information on the live weight of the plant can be obtained in real time through the live weight measuring means 150.

Figure 6 shows another embodiment of the atomizer cultivation system according to the present invention, Figure 7 shows an exploded perspective view of the main components of another embodiment of the atomizer cultivation system according to the present invention, and Figures 8 and 9 shows a cutaway cross-sectional view of another embodiment of the aeroponic cultivation system according to the present invention.

In describing this embodiment, the description of components that overlap with the previously described embodiment will be omitted or explained briefly.

The atomizer cultivation system 20 may include a cultivation chamber 270 that provides space for the roots 5 of the plant 1 to grow.

The cultivation chamber 270 may be seated and secured on the support frame 260. Among the parts of the cultivation chamber 270 that are seated on the support frame 260, the part where the load cell 251 of the live weight measuring means is located can be opened so that the load cell 251 is not affected by the cultivation chamber 270. there is.

In addition, although the bed 210 covers the upper part of the cultivation chamber 270, the bed 210 is in contact with the load cell 251 and is spaced apart from the upper end of the cultivation chamber 270, so it does not contact the cultivation chamber 270. It may not be possible.

The cultivation chamber 270 may be provided with a growth space 273 in which the roots 5 of the cultivated plant 1 can grow inside the body 271, and a lower part of the growth space 273 stores the nutrient solution. It can function as a space.

The mesh network 220 may be inserted into the growth space 273 of the cultivation chamber 270 and positioned at the middle of the growth space 273. The net 225 of the mesh network 220 may be spaced a certain distance away from the bed 210 through the support bar 231 of the support means 230 and positioned at the middle of the growth space 273 of the cultivation chamber 270. The cross-sectional area of the growth space 273 of the cultivation chamber 270 is larger than the area of the net 225 of the mesh net 220, so that the net 225 of the mesh net 220 does not contact the side wall of the cultivation chamber 270. It may not be possible.

The nutrient solution supply line 243 may extend onto the growth space 273 of the cultivation chamber 270 through the nutrient solution supply hole 275 provided on the side wall of the cultivation chamber 270. A spray nozzle 245 may be disposed on the nutrient solution supply line 243 located on the growth space 273 of the cultivation chamber 270.

The nutrient solution supplied to the growth space 273 of the cultivation chamber 270 through the nutrient solution supply means 240 may be stored and accumulated in the nutrient solution storage space provided at the lower part of the growth space 273 of the cultivation chamber 270.

Furthermore, the depth of the growth space 273 of the cultivation chamber 270 may be determined by considering the growth degree of the cultivated plant 1.

As an example, as shown in FIGS. 8 and 9, the bed 210 and the mesh network 220 are connected to each other through the support bar 231 of the support means 230 according to the growth degree of the roots 5 of the cultivated plant 1. By adjusting the distance between the plants to H1, H2, etc., more space can be secured for the roots (5) of the plant (1) to grow.

As an example, effective growth of the plant 1 can be achieved with the tip of the root 5 of the plant 1 in contact with the nutrient solution P stored in the nutrient solution storage space of the cultivation chamber 270.

Here, since the nutrient solution penetrates the mesh network 220, the mesh network 220 can actually support only the weight of the roots 5 of the plant 1. Therefore, since the weight of the nutrient solution has little effect on the load cell 251 of the live weight measuring means 150, more accurate measurement of the live weight of the plant is possible.

The bottom surface of the cultivation chamber 270 may be provided with a drain hole 277 for discharging the nutrient solution stored in the nutrient solution storage space of the cultivation chamber 270.

A nutrient solution discharge means 280 may be connected to the drain hole 277 of the cultivation chamber 270.

The nutrient solution discharge means 280 may include a drain line 281, a drain valve 285, a drain pump, etc.

The drain line 281 is connected to the drain hole 277 of the cultivation chamber 270 to discharge the nutrient solution stored in the nutrient solution storage space of the cultivation chamber 270 to the outside.

The drain valve 285 is disposed at the middle of the drain line 281 and can selectively discharge the nutrient solution stored in the nutrient solution storage space of the cultivation chamber 270 through the drain line 281.

The drain pump can discharge the nutrient solution stored in the nutrient solution storage space of the cultivation chamber 270 more quickly through the drain line 281.

Figures 10 and 11 show another embodiment of a spray cultivation system according to the present invention.

The pneumatic vibrator 291a may be placed on the upper surface of the bed 210. Preferably, the pneumatic vibrator 291a may be placed at the center of the upper surface of the bed 210.

The pneumatic vibrator 291a can cause vibration through the reciprocating motion of the piston through injected air.

One side of the air supply line 292a is connected to the pneumatic vibrator 291a and the other side is connected to the compressor 293a, so that air can be supplied to the pneumatic vibrator 291a.

The compressor 293a can generate air and provide pneumatic pressure.

The air control valve 294a is disposed at the middle of the air supply line 292a and can selectively control the air supplied through the air supply line 292a.

The vibration controller 295a may control the operation of the pneumatic vibrator 291a by controlling the opening and closing of the air control valve 294a. As an example, the vibration controller 295a may include a timer and operate the pneumatic vibrator 291a according to a time period set in the timer.

In this way, the bed 210 is vibrated through the pneumatic vibrator 291a, and the vibration is transmitted to the mesh network 220 connected to the bed 210 through the support bar 231 of the support means 230, thereby forming the mesh network 220. ) may be shaken. As the mesh network 220 is shaken, the nutrient solution present in the mesh network 220 may be removed.

As another example, as shown in FIG. 11, the vibration means 290b may include a vibration motor 291b, a power supply 293b, a vibration controller 295b, etc.

The vibration motor 291b may be placed on the mesh network 220. Preferably, the vibration motor 291b may be placed on the support frame 225 of the mesh network 220. Depending on the situation, a plurality of vibration motors 291b may be disposed at a plurality of positions on the support frame 225.

The vibration motor 291b may cause vibration depending on the application of power.

The power supply unit 293b may supply power to the vibration motor 291b.

As an example, the power supply unit 293b may include a battery and supply power to the vibration motor 291b through the battery. Alternatively, the power supply unit 293b may include a power line connected to the vibration motor 291b and supply power supplied from the outside to the vibration motor 291b through a power line.

The vibration controller 295b can control the operation of the vibration motor 291b to selectively cause vibration through the vibration motor 291b. As an example, the vibration controller 295b may include a timer and operate the vibration motor 291b according to a time period set in the timer.

Furthermore, a waterproof cover 292b may be provided to surround the vibration motor 291b, the power supply unit 293b, etc. to prevent the nutrient solution from affecting the vibration motor 291b.

In this way, the nutrient solution present in the mesh network 220 can be removed by shaking the mesh network 220 through the vibration motor 291b.

Furthermore, the nutrient solution is sprayed through the nutrient solution supply means 240, and after a certain period of time has elapsed so that the nutrient solution can be absorbed into the roots 5 of the plant 1, vibration is induced through the vibration means 290a, 290b for a set time. The remaining nutrient solution in the mesh network 220 can be removed.

By removing a small amount of residual nutrient solution that may remain in the mesh network through the vibration means described above, it is possible to reduce measurement errors caused by the nutrient solution and achieve more accurate measurement of plant live weight.

Through the present invention discussed above, the degree of plant growth can be measured non-invasively and in real time by using a cultivation device equipped with a load cell by applying spray cultivation technology.

In particular, in the present invention, the mesh network minimizes the interference of nutrient solution, which negatively affects the measurement of plant live weight, and obtains a measurement value as close as possible to the actual live weight.
