The plurality of beds 12 is made of at least one bed, and each bed 12 provides a cultivation container in which crops can be planted at regular intervals, and is installed in parallel at regular intervals. Here, if the gap between the two beds is not sufficiently secured, the crops planted in the beds may not receive sufficient light to the lower side. The specification of such a bed 12 may be implemented, for example, in a standard of 450mm * (900mm ~ 1000mm) * 90000mm (Width * High * Length), but is not limited thereto. The length of the bed can be adjusted. In addition, it is preferable that the distance (interval) between the beds in the plurality of beds 12 is installed so as to be 900 mm to 1000 mm.

The lighting unit 13 is made of a plurality of lighting trains, and each lighting train may be made of a plurality of LED crop cultivation lights. Each lighting row 13a, 13b is initially located above each bed. In the present invention, although the lighting unit 13 is illustrated as consisting of two lighting columns 13a and 13b, the present invention is not limited thereto. (where N is a natural number greater than 1). However, as an exception, in the case of configuring one bed 12 , the lighting unit 13 may be configured by one lighting train. For example, when N beds are installed, N-1 lighting columns are sequentially installed on the upper side of each bed, and the lighting unit is not installed in the last one bed.

The lighting unit 13 is formed by the surrounding environment (for example, surrounding structures such as mountains, buildings and bridges, trees, etc.) of the structure 11 or the shade and light formed by the cover of the structure 11. , 13b), the arrangement interval of the LED crop cultivation lights can be set differently. For example, when the bed 12 is located in the shaded area, the arrangement interval of the LED crop cultivation lights of the lighting rows 13a and 13b is 1000mm to 1200mm, and when the bed 12 is located in the sunny area, the The arrangement interval of the LED crop cultivation lights may be implemented to be 1500 mm.

In addition, the lighting unit 13 may determine the number of LED crop cultivation lights disposed on one crop according to various factors such as climate, surrounding environment, and spacing between planted crops. For example, one or more LED crop lamps may be designed to be adjacent to one crop.

In addition, the lighting unit 13 may be controlled to operate when the amount of sunlight is insufficient according to various conditions such as weather, season, and surrounding environment. For example, the lighting unit 13 may operate until the sunrise time after having a rest time for a certain time (eg, 2 hours) after the sunset time according to the season.

In addition, the lighting unit 13 may operate at a time before sunrise after sunset, that is, at night time. This can promote photosynthesis of plants even at night time. In this case, the on/off of the lighting unit 13 may be automatically controlled using the illuminance sensor 14 .

In addition, the lighting unit 13 is controlled to maintain operation until the illuminance value obtained through the illuminance sensor 14 becomes equal to or greater than a preset illuminance value, or based on the illuminance value measured by the illuminance sensor 14 . It may be controlled to partially operate to maintain a preset illuminance value (reference data).

In addition, the lighting unit 13 is installed so as to be positioned at an upper side of each bed 12a, 12b, 12c immediately after planting of the crop, that is, spaced apart by a preset height directly above the planted crop, and the leaves of the crop start to grow. Or it is adjusted to move between the two beds 12 just before the flower is about to form.

In addition, the lighting unit 13 is implemented to enable individual operation of each LED crop cultivation light, and only the LED crop cultivation lamp of the corresponding illumination row of the bed 12 where the leaves grow first according to the light and shade formed in the structure 11 . Position can be adjusted or turn on/off can be controlled. For example, in the case of a shaded area, a crop may grow about 1 to 2 weeks later compared to a sunny area, so a plurality of LED crop cultivation lights constituting each lighting row of the corresponding lighting unit 13 can be individually repositioned. can

In addition, each of a plurality of LED crop cultivation lights constituting each lighting row of the lighting unit 13 may emit light optimized for plant growth generated by a combination of a plurality of RED, BLUE, and ORANGE LEDs to adjacent crops. Here, the combination of a plurality of RED, BLUE, and ORANGE LEDs is arranged in a preset configuration ratio (RED LED:BLUE LED:ORANGE LED), number and arrangement pattern so that the RED LED, BLUE LED, and ORANGE LED have a wavelength band of light that is efficient for photosynthesis. can be Here, the composition ratio of RED LED, BLUE LED and ORANGE LED is based on the types of crops including root plants, fruit trees, leafy vegetables, sunny plants, and shade plants, the height and width of crops, and the size and number of leaves depending on the structure of the crop. can be selected accordingly. A detailed description of the lighting unit will be described with reference to FIGS. 4 to 7 .

The illuminance sensor 14 is installed in each zone in which the internal space of the structure 11 is divided into a plurality, and measures the illuminance (the degree of representing the brightness of light) of the installed zone in units of lux. The illuminance sensor 14 measures the illuminance value inside the structure 11 and transmits it to the control unit 16, and the control unit 16 compares the obtained illuminance value with preset reference data (reference illuminance value) and compares the result of the comparison. According to the lighting unit 13, it is possible to control the point/off of the LED crop cultivation light. For example, in the embodiment of the present invention, when the cultivation space (area) within the structure 11 is divided into A, B, C, and D, the control unit 16 may control the illuminance installed in A, B, C, and D, respectively. Obtaining the measured illuminance value from the sensor 14, comparing the obtained illuminance value with pre-stored reference data (reference illuminance value), and when the obtained illuminance value is less than the reference data as a result of comparison, illuminance to satisfy the reference data It is possible to determine the number of LED crop cultivation lights of the lighting unit (13: 13a, 13b) to be lit by the value, and to operate the determined LED crop cultivation lights. On the other hand, as a result of the comparison, when the obtained illuminance value is equal to or greater than the reference data, the number of LED crop cultivation lights of the lighting unit 13: 13a, 13b to be turned off by the illuminance value exceeding the reference data is determined, and the The lights can be adjusted to actuate. Accordingly, power consumption due to unnecessary lighting of the lighting unit 13 can be reduced, and plant growth can be promoted by maintaining light emission that can promote optimal photosynthesis required for plant growth.

The plurality of CCTV systems 15 take images to monitor the environment inside the structure 11 and the growth state of crops using a camera, and transmit the captured images to the control unit 16 .

The control unit 16 is provided in each lighting column of the lighting unit 13 in response to the degree of light blocking according to the opening and closing of the insulation cover, the ventilation device, and the vinyl cover of the structure 11, and the illuminance that varies depending on the weather. Controls whether or not to turn off/off points and the number of points/offs in crop cultivation. That is, the control unit 16 may automatically adjust the number of points/offs of the LED crop cultivation lights according to the degree of opening and closing of the cover for the structure 11 .

Specifically, the control unit 16 obtains an illuminance value according to whether the cover is opened or closed from the plurality of illuminance sensors 14, compares the obtained illuminance value with pre-stored reference data (reference illuminance value), and the comparison result obtained It is determined whether the illuminance value is less than or greater than the reference data, and in response to the determination result, whether the LED crop cultivation light provided in each lighting column 13a, 13b of the lighting unit 13 in the structure 11 is turned off/off and the point /Determine the number of lights out. That is, the control unit 16 turns off the LED crop cultivation light if the obtained illuminance value is greater than or equal to the reference data as a result of the determination, and turns on the LED crop cultivation lamp if it is less than, but the LED crop is in proportion to the difference between the obtained illumination value and the reference data It is possible to determine the number of lighting of the cultivation lamp.

For example, when the cover of the structure 11 is open, the control unit 16 turns off the LED crop regeneration light, but meets the preset reference illuminance value corresponding to the illuminance value obtained by the illuminance sensor 14 Determine the number of lights out, and when the cover of the structure 11 is closed, turn on the LED crop regeneration light, but set the number of lights to meet the preset reference illuminance value corresponding to the illuminance value obtained by the illuminance sensor 14 decide Accordingly, it is possible to reduce unnecessary power consumption by reducing the provision of an excess amount of light, and at the same time, it is possible to induce optimal plant growth by supplementing the insufficient amount of light.

For reference, since photosynthesis no longer occurs above the light saturation point even if the amount of light (PPFD: Photosynthetic Photon Flux Density) continues to increase, the amount of light for plant growth is preferably within the light saturation point above the light compensation point.

In addition, the control unit 16 acquires the illuminance value inside the structure 11 measured by the illuminance sensor 14 in response to the sunrise/sunset time, and uses the obtained illuminance value to the illumination unit 13 according to sunrise/sunset It is possible to automatically control the on/off of each LED crop cultivation light of For example, the control unit 16 obtains an illuminance value in the structure 11 according to sunrise/sunset from the illuminance sensor 14, and compares whether the obtained illuminance value is less than or equal to preset reference data (reference illuminance value) And, if the illuminance value obtained as a result of comparison is less than the reference data, it is determined as sunset and the LED crop cultivation lamp in the structure 11 is controlled to be turned on. ) Automatically controls my LED crop growing lights to turn off. At this time, the control unit 16 sets a rest time (eg, 2 hours) for stopping photosynthesis and respiration after sunset, and controls to turn off the LED crop cultivation light during the break time and then turn it on again.

Accordingly, the control unit 16 can promote plant growth by creating a photosynthetic environment optimized for plant growth by automatically controlling the on/off of the lighting unit 13 in the structure 11 using the illuminance sensor 14 .

As such, in the present invention, the lighting time of the lighting unit according to the control of the controller 16 may be from 30 minutes just before sunrise to the time of opening the cover. For example, since the temperature is low in winter and the cover is covered even after sunrise, the lighting unit is turned on from 5:30 am to just before the cover is opened. In addition, for the lighting time of the lighting part, lighting is performed from the time when the shade is dark to the time of sunset in the shaded area, and a break time of about 2 hours after sunset in the sunny area, and then lighted from 1:30 to 2:00 minutes. After that, the lights are turned off, and in places in the shade, turn off the lighting part at sunset, have a break for about 2 hours, and then turn off the lights after 1:30 to 2:00 minutes.

In addition, the control unit 16 performs image processing and image recognition on the image transmitted from the CCTV system 15 to monitor the growth of the crop, determine the growth stage of the crop through growth monitoring, and determine the crop The position of the lighting unit 23 is automatically adjusted in response to the growth stage of For example, the control unit 16 positions the lighting unit 13 on the upper side of the crop, that is, on the upper center of the bed, immediately after planting the crop, and through growth monitoring, the growth stage of the crop is the growth period or flowering period of the leaves. If confirmed, the position of the lighting unit 13 is adjusted between the two beds.

This control unit 16 may be implemented with a notebook computer, a computer, etc., and collects and acquires data through a wired/wireless communication network or is electrically connected to each component, and turns on/off the LED crop cultivation lights of the lighting unit 13 and Position control can be performed.

On the other hand, although not shown, the crop cultivation system according to the present invention may include various sensors, and the control unit 16 may perform appropriate control to promote plant growth using the sensing information obtained from each sensor. have. For example, in the crop cultivation system of the present invention, a means for supplying moisture in the structure 11 (a water sprayer, a sprinkler, a water supply hose, etc.), a means for supplying a nutrient solution, and a means for air circulation (a fan) , cover opener, etc.) may be installed in the structure, and humidity, temperature, and water injection amount are set to be suitable for the growth of plants and automatically control them through the control unit 16 to improve the growth of plants. An optimal environment can be provided.

As described above, according to the crop cultivation system according to the present invention, a lighting unit configured by combining a plurality of LEDs to emit light suitable for photosynthesis is used. By adjusting the position of the plant growth can be promoted.

FIG. 2 is a view for explaining a process in which a bed and an LED crop cultivation light are disposed and a control unit adjusts a position of a lighting unit in the crop cultivation system shown in FIG. 1 .

Referring to FIG. 2A , in the crop cultivation system 10 according to the embodiment of the present invention, first, when a crop is planted in the cultivation container of the bed 12 , the control unit 16 controls the lighting unit 13 ), the LED crop cultivation lights constituting each lighting row are controlled to be located above each bed 12 , and the light of the lighting unit 13 is adjusted so that the light of the lighting unit 13 is directly directed toward the crops planted in the bed 12 . At this time, the installation height of the lighting unit 13 is a height spaced apart by a predetermined interval (d) from the top of the seedling of the planted crop, and the predetermined interval (d) is determined differently depending on the type of crop and the size (growth height) of the crop. . For example, the predetermined interval (d) is preferably in the range of 800 to 900 mm for crops with a low growth height of crops, such as strawberries, and 500 to 600 mm for crops with high growth heights, such as cherry tomatoes.

Then, referring to FIG. 2 (b), the control unit 16 monitors the degree of growth of the plant from the image captured in real time from the CCTV system 15, checks whether the crop is flowering or the size of the leaf, and the result of the check When the flowering of crops or the growth of leaves (the size of the leaves has grown beyond a certain level) is confirmed, the LED crop cultivation lights located above each bed 12 are moved to be located between the two beds 12 . At this time, the installation height of the moved lighting unit 13 is a height spaced apart by a predetermined interval (d) from an intermediate position between the position of the top leaf and fruit of the grown crop, and the predetermined interval (d) is the type of crop, It may be determined differently depending on the size (height) of the crop. For example, the predetermined interval (d) is preferably in the range of 800 to 900 mm for crops with a low crop height, such as strawberries, and 500 to 600 mm for crops with high crop heights, such as cherry tomatoes.

By adjusting the position of the lighting unit 13 so that the optimal light is irradiated according to the growth of the crop, it is possible to induce the growth of the crop.

For reference, the hypertrophy according to the growing season of a plant varies depending on the growing season from reproductive growth to vegetative growth and from kidney growth to seed growth. At first, the leaves grow bigger and the number increases, and photosynthesis grows a lot, and after seed generation, it concentrates on fruit production. That is, in the early period of growth, the growth of leaves should be promoted and plant growth should be aided, and in the late period of growth, the growth of the leaves is suppressed (to prevent the number of leaves from increasing), so that the edible parts (eg, fruits) become enlarged. In the present invention, according to the growth period, the growth stage of the crop is divided into the first stage before the kidney growth and the second stage after the kidney growth.
