Description

[0001] The present invention relates to an automatic high-cultivating system based on human-machine-

The present invention relates to a HMC-based automated high-yield cultivation system.

It is a plant for cultivating crops at a higher level than the surface of the ground. It is often used for the cultivation of strawberries, drop tomatoes, melons and the like, although it is often used for growing vegetables or fruit seedlings.

Strawberries, drop tomatoes or melons are low in crops, so they are prone to all the cultivation work. Therefore, the labor intensity is higher than other crops, and the harvesting and cultivation period is long. It has been increasingly used as a high-quality cultivation equipment for cultivating work, which is improving productivity.

In recent years, unstable supply and demand of agricultural products has been continuing due to the phenomenon of abnormal weather, and plant plant systems are being developed to realize stable cultivation irrespective of environmental changes.

A plant plant is a system that automatically controls the environmental conditions such as light, temperature, humidity, carbon dioxide concentration, and culture liquid in a controlled facility, and automatically produces them continuously regardless of season or place.

This is a state-of-the-art agricultural production technology that combines science and technology in various fields such as agriculture, architecture, facilities, machinery, electronic control, and biological information analysis. As such, plant factories have the characteristics of precision agriculture that scientifically manages the growth conditions of crops and puts fertilizer and pesticide low. Therefore, it can secure safety compared to general agricultural products.

In addition, it is possible to realize high-value-added agriculture by cultivating functional crops that are difficult to cultivate in the open field, and it can be utilized as a food base by dramatically increasing productivity through cultivation of food crops throughout the year. .

Prior art 1 discloses that it is possible to independently maintain and operate electricity by using the power of the internal combustion engine and thereby to stably supply the light energy required for the plant through the artificial light source, Desc / Clms Page number 2 > plant plant system which is evacuated to a plant factory in a purified state.

In the case of Prior Art 1, the contents of the independent operation of the plant plant through the internal combustion engine and the maintenance of the internal temperature of the plant plant by recovering waste heat of the exhaust gas of the internal combustion engine are described. However, Technology is not applied.

On the other hand, regarding the relation between the water content in the medium and the growth of the crop, the proper water content in the medium has a great influence on the growth of the crop. Generally, when the water content in the medium is high, the crops grow nutritionally, and when the water content is low, they reproduce. However, excessively high water content in the medium adversely affects the roots of the crops, and too low a water content is good for the development of the roots, but it is very important for the crops to easily wilting under severe light conditions.

Changes in water content in the medium during the day also have a great influence on the growth of the plants, so that the growth of the crops can be controlled by using the difference in water content during the day.

The moisture content in the medium is a factor that influences the weather (minimum 25%, optimum weather rate 30 ~ 40%) among the three phases of the rhizosphere (gas phase, liquid phase and solid phase) Because the energy produced by the plant affects both water and moisture absorption during the day, the water content must be reduced enough to improve muscle respiration.

If there is insufficient respiration, the lower legs become sulphuric. It is necessary to control the water content in accordance with the increase of the yield depending on the cultivation time. In general, it is difficult to manage the moisture in the medium because the increase in lightness tends to decrease even if the light is good during the period from January to February. Therefore, it is necessary to control the amount of water based on the amount of water, because the water content is excessively increased and the development of root is weakened when the amount of drainage is maintained at 25 ~ 30% during January ~ February.

Therefore, the measurement of the water content is an important factor in crop cultivation using the medium.

The conventional method of measuring moisture content is most commonly the ovendrying method in which oven-dried weight is measured by drying in an oven. The sample is sampled, weighed, dried in an oven, weighed, There is a problem in that it is difficult to apply to the cultivation of the crop using the medium in view of the water content measurement procedure for measuring the content and the long time and difficulty in grasping the water content in real time.

In the prior art 2, infrared thermometers, halogen lamps, a data acquisition system, a computer, and correction coefficients are installed in a simple manner for any process requiring estimation of nondestructive moisture content such as food or other materials as well as wood A non-destructive water content measurement method is disclosed.

In addition, in the prior art 3, a probe for measuring the water content of an object to be measured is provided. The probe includes a heater for generating a predetermined amount of heat, a heating rod for conducting a predetermined amount of heat to the object through the heater, A temperature sensor unit for detecting the temperature of the water and a temperature sensor unit for measuring the temperature detected through the sensor bar, the indicator including a microcomputer for controlling the temperature of the heater unit and receiving a signal through the temperature sensor unit, A correction data input / output unit for providing the microcomputer with correction data relating to the water content of the object to be measured; and a microcomputer for receiving the correction data and the control signal of the microcomputer from an external computer, A moisture content measuring device comprising a connection port for outputting the water content measurement data of the microcomputer to an external computer is disclosed It can control.

However, prior arts 2 and 3 are technologies necessary to control the amount of nutrient solution to be supplied to plants in a state in which information on the water content necessary for plant growth has already been obtained.

In other words, there is no problem in controlling the feed rate of the nutrient solution by measuring the water content of the nutrient in the state that the water content is different depending on the type of the plant and the data of all the plants are retained. However, have.

Even if plants are planted in the data and the amount of nutrient solution is checked on a daily basis, it is difficult to know whether or not the plants are maximally grown according to the supply amount, so that it is difficult to obtain accurate basic data according to the growth.

2. Portable light source and water supply (including nutrient solution)

The plant growth state is grasped by the camera unit 300 through image processing (side-plant height, upper-plant growth distribution, slanting line-flesh size, etc.) and compared with the input reference growth information, And controls the growth management unit 500 so that a light source and irrigation water are provided at a portion where additional nutrient supply is required.

Here, the movable light source and the water supply configuration are modularized (the light source and the irrigation supply structure are moved along the frame in the ∩ type frame) and are arranged at regular intervals in the plant factory, and each module is installed in the guide rail configuration A motor, a belt, and the like), so as to provide a light source and an irrigation water while moving within a corresponding area of each module.

3. Configuration of solar cell

We installed transparent solar cells on the ceiling and sides of plant factories to supply the energy from solar power generation to plant factories (at all times). In addition, when the commercial power cutoff It is used as auxiliary power.

In addition, it is also possible to adopt a configuration for maximizing the power generation efficiency of the solar cell by adding a mounting structure capable of supporting the solar cell on the side of the plant plant and adjusting the tilt angle. That is, it is possible to maximize the efficiency of the sunlight irradiated to the solar cell by changing the installation surface of the solar cell (side of the plant) side in real time according to the irradiation direction of sunlight from sunrise to sunset.
