Description

Green wall system using artificial intelligence {GREEN WALL SYSTEM USING AI}

The present invention relates to a green wall system using artificial intelligence.

Recently, because modern people spend 80 to 90% of their time indoors in a limited way, Microbial contamination has a fatal adverse effect on the health of residents.

According to this trend, in the past, the construction industry mainly invested in exterior materials and landscaping of apartments, but now, the emphasis is on eco-friendly composition, comfort, and improvement of indoor air quality. The demand for the improvement of the eco-friendly quality of life for the internal residential environment rather than the residential environment is increasing.

In the current living environment, efforts are being made to create a more nature-friendly living environment by managing indoor air quality and creating an indoor landscaping. Accordingly, indoor gardens are being actively developed.

However, in indoor gardens, sunlight cannot be sufficiently irradiated indoors, so LED lights for plant cultivation are additionally installed to replace sunlight and irradiate light wavelengths of specific bands that affect plants. For example, in the case of blue light with a wavelength of 450 nm, growth is inhibited and flower bud formation is promoted. And in the case of red light with a wavelength of 660 nm, chlorophyll is produced by promoting the growth of leaves and stems and applied to photosynthesis. Therefore, LED lighting for plant growth is an essential element inducing plant growth, fruiting flowering, and the synthesis of functional substances by controlling it to replace sunlight that cannot be sufficiently irradiated to the indoor garden.

9 is a view showing the LED light for plant cultivation according to the prior art, and FIG. 10 is a view showing the state of cultivating plants in the plant cultivation apparatus using the LED light for plant cultivation according to the prior art.

As shown, in the prior art, a white LED package (1) and a red LED package (2) are repeatedly arranged in the LED light (3) for plant cultivation in order to implement a wavelength suitable for plants. As shown in FIG. 11 , the indoor plant cultivation apparatus using the LED light 3 for plant cultivation configured as described above is suitable for plant growth because pink color is expressed, but for interior use, it gives fatigue to the human eye and color rendering properties. (演色性; a phenomenon that affects the color of an object depending on the light source) is low, so it is difficult to understand the color and shape of the plant. In addition, when the red light LED package (2) and the white light LED package (1) are crossed and used in series connection, one red light LED package (2) and one white light LED package (1) must be configured as one set for plant growth. Since it is possible to implement a target spectrum, there is a problem that requires a considerable volume and area.

In addition, the indoor cultivation method as shown in FIG. 10 is a method in which LED lights for plant cultivation are horizontally arranged on the upper part of the plant to be cultivated, so the efficiency of space use is low and the plant cultivation apparatus cannot be used for indoor air purification or interior. there was
