Description

Technology Field

[0001] The present invention relates to a plant cultivation device, and more specifically, to a lighting device and control system for plant cultivation that can recognize plant type information from a pot in which a plant is planted and create and provide an optimal plant growth environment based on AI. Background Technology

[0003] In general, providing suitable growth conditions for plants is very important, and it is well known that light in a specific wavelength range (350–740 µm) affects plant growth during cultivation.

[0004] For example, blue light (470 μm) is known to be necessary to grow and thicken stems and roots or to increase lateral roots (fine roots), and red light (660 μm) is known to be necessary to promote the growth of leaves and stems, produce chlorophyll, and perform photosynthesis.

[0005] Recently, light-emitting diodes are being used as lighting for plant cultivation to provide a suitable environment necessary for plant growth. Since these light-emitting diode lights operate at low power and can provide light in a specific wavelength band, they can increase the photosynthetic efficiency of plants while also generating energy saving effects. Prior art literature

[0007] Prior Art 1: Korean Registered Patent No. 10-0879711 Prior Art 2: Korean Registered Patent No. 10-1819585 Prior Art 1 Korean Registered Patent No. 10-0879711 discloses a lighting device for plant cultivation using light-emitting diodes, and a technology is known that can promote germination, flowering, and growth of plants by appropriately mixing and configuring the ratio of light emitted from light-emitting diodes according to specific wavelength ranges. In addition, prior art document 2, registered patent No. 10-1819585, discloses a technology for a plant cultivator equipped with an LED lighting device capable of changing wavelengths. However, this device is equipped with lighting modules having different wavelengths, and these lighting modules are rotated for use when the crop is changed. Nevertheless, such conventional lighting devices for plant cultivation are manufactured to suit specific plant types and growth processes, so the wavelength and light intensity of the lighting device cannot be changed when the crop is changed. Furthermore, although the light energy required by the plant varies depending on the growth stage during the growth process, the same wavelength and light intensity are provided throughout the entire growth period, resulting in significant energy loss. There is also the disadvantage that the lighting device must be replaced when the plant to be cultivated changes. The problem to be solved

[0008] The present invention is designed to improve upon the aforementioned problems and aims to provide a lighting device and control system for plant cultivation that recognizes information on the type of plant planted in a pot, provides an optimal cultivation environment suitable for the plant type, and enables energy savings and reduced facility costs. means of solving the problem

[0010] To achieve the above objective, the plant cultivation device according to the present invention comprises: a light source unit that irradiates light onto a pot in which a plant is planted; a plant type recognition unit that recognizes the type of plant planted in the pot; and a control unit that extracts cultivation environment information corresponding to the plant type recognized by the plant type recognition unit and controls the wavelength, intensity, and amount of light emitted from the light source unit based on AI according to the extracted cultivation environment information; wherein the light source unit comprises a plurality of red light-emitting diodes that emit red light; a plurality of blue light-emitting diodes that emit blue light; a plurality of ultraviolet light-emitting diodes that emit ultraviolet light; and a plurality of white light-emitting diodes that emit white light; wherein the red light-emitting diodes, the blue light-emitting diodes, the ultraviolet light-emitting diodes, and the white light-emitting diodes are arranged at mutually set ratios and mounted within a smart lighting case so as to be spaced apart from each other.

[0011] According to one aspect of the present invention, the red light-emitting diode, the blue light-emitting diode, the ultraviolet light-emitting diode, and the white light-emitting diode are mixed in a ratio of 4:2:1:10 and mounted in the dimming case.

[0012] In addition, the plant type recognition unit comprises: a tag or information storage medium of the port mounted on the port, on which plant type information is recorded in a contact or non-contact manner; and a recognition sensor attached to a port holder that reads the information recorded in the tag or information storage medium and provides it to the control unit.

[0013] The above AI-based control system comprises: a sensor input unit that inputs environmental measurement data from external environment-related sensors; an information database that stores growth environment information corresponding to plant types; an AI cultivation environment inference system that extracts cultivation environment information of a plant recognized by a recognition unit from the database and intelligently optimizes the wavelength, intensity, and amount of light by referring to the extracted cultivation environment information and environmental sensor data; and a control unit that controls an optimized lighting device for plant cultivation based on the growth environment information extracted by the inference system. Effects of the invention

[0015] According to the lighting device for plant cultivation of the present invention, information on the type of plant planted in a pot is recognized, and a lighting environment corresponding to that type of plant is found and provided, thereby increasing the convenience of providing a growth environment. In addition, even if the type of cultivated plant changes, optimal lighting control is possible without changing the lighting device for efficient energy management, which can significantly contribute to energy and cost reduction, and energy savings of approximately 40-50% are possible compared to commercial LED plant lighting. This is because, assuming that a commercial product continuously uses 100 units of energy every day from germination to harvest under the same conditions, the device of the present invention gradually grows the plant using 30%, 50%, 70%, and 100% of energy in accordance with the growth cycle during that period, thereby saving that amount of energy.

[0018] Hereinafter, a lighting device and control system for plant cultivation according to a preferred embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0019] FIG. 1 is a diagram showing the configuration of an LED array of the light source unit of an LED lighting device for plant cultivation according to the present invention.

[0020] Referring to Fig. 1,

[0021] The light source unit (100) is controlled by an intelligent complex environment controller (see FIG. 4) and irradiates light onto plants planted in a pot.

[0022] The light source unit (100) is equipped with a plurality of red light-emitting diodes (LEDs) (101) that emit red light, a plurality of blue light-emitting diodes (LEDs) (102) that emit blue light, a plurality of ultraviolet (UV) light-emitting diodes (LEDs) (103) that emit ultraviolet (UV) light, and a plurality of white light-emitting diodes (LEDs) (104) that emit white light.

[0023] Here, a red light-emitting diode (101) with a center wavelength of 660 nm, a blue light-emitting diode (102) with a center wavelength of 460 nm, an ultraviolet light-emitting diode (103) with a center wavelength of 400 nm, and a white light-emitting diode (104) are arranged to be mixed in mutually set ratios and mounted in a light-emitting case (see FIG. 1) so as to be spaced apart from each other.

[0024] As an example, a red light-emitting diode (101), a blue light-emitting diode (102), an ultraviolet light-emitting diode (103), and a white light-emitting diode (104) are mixed in a ratio of 4:1:2:10 and mounted inside a light-emitting case, reflecting the wavelength ratio that takes into account plant growth and growth stages.

[0025] The mixing ratio of these light-emitting diodes by wavelength is set considering the optimal lighting conditions for each growth stage of various plants, enabling the provision of optimal lighting to diverse plants requiring different lighting conditions.
