Description
Technical Field
The invention relates to the technical field of biological illumination systems, in particular to a dynamic light source device, a system and a method for agricultural illumination.
Background
The plant factory combines modern industry, biotechnology, nutrient solution cultivation, information technology and the like, carries out high-precision control on environmental factors in facilities, has the advantages of full sealing, low requirements on surrounding environment, shortening the plant harvesting period, saving water and fertilizer, no pesticide production, no waste discharge and the like, and has the unit land utilization efficiency 40-108 times of that of open field production, wherein the intelligent artificial light source and the light environment regulation play a decisive role in the production efficiency. Light is used as an important physical environment factor, and plays a key role in regulating and controlling the growth and development of plants and the metabolism of substances. One of the main characteristics of the plant factory is a fully artificial light source and the intelligent regulation of the light environment is realized, which is a common consensus in the industry. However, the existing plant illumination lamp can realize continuous output of crops all the year round through manual control illumination, watering, fertilization and the like. However, the existing plant light lamps are fixedly arranged, and the illumination adjustment of plants is realized by selectively turning on and off the plant light lamps. The plant light lamps needed in the method are more in number and higher in cost, and in addition, the illumination of plants is not flexibly adjusted, so that the adjustment operation is troublesome. Meanwhile, the electricity charge in the production cost of the plant factory is about 30%, and if no cheap power supply and high-efficiency artificial lamplight are adopted to reduce the production cost, the plant factory is not attractive to farmers. Thus, the development of a resource-saving light source is a necessary requirement for the construction of plant factories.
For example, chinese patent publication No. CN111174153a discloses a sports type plant light supplementing device, which includes a light supplementing unit and a guide rail unit, the light supplementing unit includes a movable bracket, a light supplementing lamp mounting frame disposed on the movable bracket, and a plurality of plant light supplementing lamps disposed on the light supplementing lamp mounting frame; the guide rail unit comprises a fixed bracket and a guide rail connected with the fixed bracket; the movable support is movably connected with the guide rail; the movable support is provided with side support legs respectively positioned at two sides of the guide rail, the tail ends of the side support legs are rotatably connected with travelling wheels, and the travelling wheels are in butt joint with the guide rail; one of the travelling wheels is connected with a driving device. Therefore, the number of the required plant light lamps is reduced, the cost is reduced, and the plant illumination is flexibly and conveniently adjusted. The inventors have found that the following technical deficiencies still exist: the light source (such as an LED) used in the invention is prone to form white light by mixing a plurality of kinds of fluorescent powder in a certain proportion, the white light LED is matched with fluorescent conversion devices with different wavelengths to work when light is emitted, the power consumption is high, the light conversion efficiency is low, the number of required LED lamps is large, the energy consumption of the whole illumination system is high, and the light utilization rate of the LED of the illumination system is not high. Therefore, how to meet the illumination requirements of animals and plants under the limited light source, thereby achieving the purposes of reducing the investment of fixed equipment (illumination system) and reducing the power consumption and the energy consumption expenditure of daily operation are the technical starting points of the invention. There is a need for improvements that address the deficiencies of the prior art.
Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a dynamic light source device, a system and a method for agricultural illumination.
The dynamic light source method comprises the following steps: the image acquisition part acquires images and/or videos of animals and/or plants in the designated area; a control part acquires the image and/or video of the animal and/or plant shot by the image acquisition part; the control part analyzes and identifies basic data information of the animals and/or plants according to the images and/or videos of the animals and/or plants acquired by the image acquisition part, and controls the illumination part to provide the animals and/or plants with light meal conforming to the requirement of the basic data information according to the basic data information.
The dynamic light source system at least comprises an illumination part, a moving part and a control part. The illumination portion is configured to be able to provide high energy illumination to animals and plants within the planting/breeding area. The moving part is used for connecting the illumination part so that the illumination part can at least move along with the moving part. The control section can be used at least for controlling the movement of the moving section.
Under the condition that the control part can acquire the corresponding illumination demands of the animals and the plants, the control part is configured to provide illumination for the animals and the plants in a narrow-band mode based on the illumination demands of the animals and the plants so as to reduce the electric energy consumption of the illumination system while meeting the illumination demands required by the growth of the animals and the plants.
According to a preferred embodiment, the illumination section includes at least a monochromatic light unit and a light distribution structure unit. The monochromatic light unit can emit high-energy monochromatic light, and the light distribution structure unit can enable the monochromatic light to be converged into a narrow band with a smaller emergent range and intensively emitted to the animals and plants. Because for plants receiving photons with the same energy, the growth promoting effect of the plants brought by short-time high light intensity is better than the growth promoting effect of the plants brought by long-time low light intensity. Therefore, the light distribution structure unit can enable the monochromatic light to be converged into a narrow band with a smaller emergent range and intensively emitted to the animals and plants. Under the condition of the same energy consumption, compared with the average stepwise arrangement of a plurality of light sources, the light sources (namely the monochromatic light units) are intensively arranged and projected on animals and plants in a smaller range, and the illumination mode has better growth promotion effect on the animals and plants. Through the configuration mode, the illumination part only adopts a small number of LED lamps, then light emitted by the LED lamps of the monochromatic light units is converged to the light emitting structure through the light distribution structure units (such as focusing lenses, fresnel lenses and the like), and is projected to animals and plants through the light emitting structure framework, so that the light emitted by the small number of LED lamps can be converged to form a narrow-band light band through the illumination part to obviously enhance the light intensity of emergent light, and the light band with higher light intensity is projected to the animals and plants, thereby not only meeting the illumination required by the growth of the animals and the plants, but also obviously reducing the power consumption of the illumination system/device/equipment and improving the electric energy utilization efficiency of the illumination part to a certain extent, namely realizing the technical effect of obviously saving energy.
According to a preferred embodiment, the moving part is configured such that the illumination part moves along with the moving part and irradiates the animals and plants with light generated by the illumination part in a scanning manner. The illumination part can rotate in a static state or along the axial direction of the moving part, so that the incidence direction of the light emitted by the illumination part to the animals and plants is continuously changed, and the irradiation dead angle generated when the light generated by the illumination part is emitted to the animals and plants is reduced.
According to a preferred embodiment, the illumination part further comprises a light feedback analysis unit, and the light feedback analysis unit at least comprises a light-emitting plate subunit and a light sensor arranged on the light-receiving surface of the light-emitting plate subunit. In the case that the light receiving surface of the light emitting plate subunit is coated with fluorescent powder, the light emitting plate subunit is configured to be placed on the light receiving surface side of the plant root, so that the light generated by the illumination part and/or leaked by natural light passing through the plant leaves is fully utilized to excite the fluorescent powder on the light receiving surface side of the light emitting plate subunit to emit light required by the plant, and the light can be irradiated to the plant. By the arrangement mode, the side, facing the plants, of the monochromatic light unit can be coated with fluorescent powder, so that the fluorescent powder on the monochromatic light unit can be excited again by the light emitted from the light-emitting plate subunit to the monochromatic light unit to generate light emitted to the plants, and the utilization rate of the light emitted by the monochromatic light is improved.
According to a preferred embodiment, the light feedback analysis unit further comprises a light analysis statistics subunit. The light analysis and statistics subunit can record the photon number captured by one side of the light receiving surface of the light emitting board subunit and/or the energy excited by the fluorescent powder by the light sensor, can analyze and obtain growth vigor information of the plant based on the photon number and/or the energy excited by the fluorescent powder, and can send the photon number and/or the energy excited by the fluorescent powder to the control part so that the control part can adjust illumination provided for the plant.
According to a preferred embodiment, the control module further comprises a database recipe unit. In the case that the database recipe unit is capable of obtaining the energy of the excited fluorescent powder sent by the light analysis statistics subunit, the database recipe unit is configured to form and/or update a light meal database matching the illumination requirement of the plant based on the energy of the excited fluorescent powder.
According to a preferred embodiment, the light receiving surface of the light emitting panel subunit comprises a first region. The concentration of the fluorescent powder in the first area can be gradually reduced or increased along the radial direction and the outer direction of the plant stem part by taking the plant stem part as the center, so that the light analysis and statistics subunit can at least obtain the growth condition of the plant leaf based on the change analysis of the photon quantity captured by one side of the light receiving surface of the light emitting plate subunit or the energy excited by the fluorescent powder, and then can analyze and obtain factors influencing the plant growth so as to optimize the light meal database.
For example, since the concentration of the phosphor in the first region is decreased radially outward along the stem of the plant centering around the stem of the plant, it may be divided into a first annular band, a second annular band, a third annular band, and so on. Preferably, the width of each endless belt is uniform. Thus, when the incident angle of the light emitted by the monochromatic light unit to the plant changes, the light analysis and statistics subunit integrated with or arranged on the light receiving surface of the light emitting plate subunit can judge or determine the specific growth condition of the plant leaf through the photons which are received by the different annular bands and are missing from the plant leaf (for example, the leaf at the top is rare, or the leaf at the root is rare, or the leaf at one side or all leaves at one side is less than the normal level of the plant).
Particularly preferably, the light analysis and statistics subunit is capable of determining from which part of the plant the missing light is incident or missing into the first region, based on the trend of the energy excited by the phosphor in each of the annular bands during the movement of the missing light within the first region.
According to a preferred embodiment, the light receiving surface of the light emitting plate subunit further comprises a second area, wherein the fluorescent powder of the second area is coated on the light receiving surface of the light emitting plate subunit in the second area in a mode of same concentration, so that the fluorescent powder of the second area can be directly excited by the light emitted by the monochromatic light unit and/or natural light which is not blocked by plants to generate light which can be used for plant growth, and the side of the illumination part facing the plants can be coated with the fluorescent powder, so that the fluorescent powder on the illumination part can be excited again by the light emitted from the light emitting plate subunit to the illumination part to generate the light which is emitted to the plants.

Detailed Description
The following detailed description refers to the accompanying drawings.
Fig. 1 and 2 illustrate a dynamic light source system. The dynamic light source system at least comprises an illumination part 1, a moving part 2 and a control part 3.
The illumination section 1 is configured to be able to provide high energy illumination to animals and plants within a planting/breeding area;
The moving part 2 is used for connecting the illumination part 1 so that the illumination part 1 can at least move along with the moving part 2.
The control unit 3 can be used at least for controlling the movement of the moving unit 2.
In case the control part 3 is capable of obtaining the illumination requirements of the animals and plants, the control part 3 is configured to be capable of providing illumination to the animals and plants in a narrowband manner based on the illumination requirements of the animals and plants so as to reduce the power consumption of the illumination system while meeting the illumination requirements required for the growth of the animals and plants.
Particularly preferably, the illumination section 1 comprises at least one monochromatic light lamp unit 101. Preferably, the monochromatic light lamp unit 101 may employ an LED lamp. Under the condition that the control part 3 can acquire the requirements of different plants corresponding to the illumination part 1 and different growth stages of the same plant on the light formula, the control part 3 can use the LED core light technology to combine different proportions and intensities of lights with different colors such as red, orange, yellow, green, blue and purple, and the like, thereby not only meeting the energy requirement of photosynthesis of the plants, but also being suitable for the accurate control of the growth and development of the plants, saving energy and cost in production, and further preparing the most suitable light formula.
According to a preferred embodiment, the illumination section 1 comprises at least: a monochromatic light unit 101 and a light distribution structural unit. The monochromatic light unit can emit high-energy monochromatic light, and the light distribution structure unit can enable the monochromatic light to be converged into a narrow band with a smaller emergent range and intensively emitted to the animals and plants.
For plants receiving photons of equal energy, the growth promoting effect of the short-time high light intensity on the plants is better than the growth promoting effect of the long-time low light intensity on the plants. Particularly preferably, the light distribution structure unit can concentrate the monochromatic light into a narrow band with a smaller emergent range and concentrate the monochromatic light to the animals and plants. Under the condition of the same energy consumption, compared with the average stepwise arrangement of a plurality of light sources, the plurality of light sources (namely the monochromatic light lamp units 101) are intensively arranged and projected on animals and plants in a smaller range, and the illumination mode has better growth promotion effect on the animals and plants.
Preferably, the mono-color lamp unit 101 may be an LED lamp manufactured to emit light vertically downward. Preferably, the LED lamp of the mono-color lamp unit 101 may also be manufactured as an inter-plant light supplement lamp that emits light at three hundred sixty degrees close to the plant.
Preferably, the light distribution structural unit may include, but is not limited to: focusing lenses, fresnel lenses, light extraction structures, etc. Preferably, the light distribution structure unit can collect the monochromatic light generated by the monochromatic light lamp unit 101 in a smaller light emitting structure and emit the collected illumination with higher energy to the area where animals and plants are located in a narrow-band mode.
Preferably, the light emitting structure may be in the shape of an elongated narrow strip or slit. Preferably, the light emitting structure may also be circular arc or ring. For example, the light distribution structure unit can collect the light emitted by the LED lamp of the monochromatic light lamp unit 101 to the light emitting structure through devices such as a focusing lens and a fresnel lens, and the light is projected to animals and plants through the light emitting structure. Preferably, the light emitting structure may be in a strip shape or a linear shape.
Preferably, the shape of the light emitting structure can be flexibly set according to the actual illumination requirement. By means of the configuration mode, the illumination part 1 only adopts a small number of LED lamps, then light emitted by the LED lamps of the monochromatic light lamp unit 101 is converged to the light emitting structure through the light distribution structure unit (such as a focusing lens, a Fresnel lens and the like), and is projected to animals and plants through the light emitting structure, so that the light emitted by the small number of LED lamps can be converged to form a narrow-band-shaped light band through the illumination part 1 to obviously enhance the light intensity of the emergent light, and the light band with higher light intensity is projected to the animals and plants, thereby the illumination required by the growth of the animals and plants is met, the power consumption of the illumination system/device/equipment can be obviously reduced, the electric energy utilization efficiency of the illumination part 1 is improved to a certain extent, and the technical effect of obvious energy conservation is achieved.
According to a preferred embodiment, the moving part 2 is configured such that the illumination part 1 moves along with the moving part 2 and irradiates the animals and plants with light generated by the illumination part 1 in a scanning manner. The illumination part 1 can rotate in a static state or along the axial direction of the moving part 2, so that the incident direction of the light emitted by the illumination part 1 to the animals and plants is continuously changed, and the irradiation dead angle generated when the light generated by the illumination part 1 is emitted to the animals and plants is reduced.
Preferably, the moving part 2 may include a rail unit and a lifting unit. Preferably, the rail unit is capable of horizontally moving by acquiring a control signal from the control unit 3.
It is particularly preferred that the rail unit is rotatable along a point inside or outside the rail unit. Preferably, the lifting unit is capable of lifting the rail unit in a vertical direction.
It is particularly preferred that the monochromatic light unit 101 and the rail unit are rotatably connected by a rotation unit.
It is particularly preferable that the turning unit is capable of acquiring the control signal transmitted to the turning unit by the control section 3 and controlling the mono-color lamp unit 101 to hold or adjust the direction of the light emitting structure of the mono-color lamp unit 101 in a static manner or in a manner of turning in the axial direction of the rail unit. Through this configuration mode, the emergent light direction of emergent light that monochromatic light unit 101 sent can be adjusted according to the demand that animal and plant actually grows, and the unit that rotates promptly can make the emergent light that monochromatic light unit 101 sent shoot to the plant with different incident angles to reduce the dead angle that emergent light irradiated the plant. For example, when the rail unit makes the monochromatic light unit 101 reciprocate or rotate longitudinally along a plane (e.g., a horizontal plane), the monochromatic light unit 101 can rotate clockwise or counterclockwise along the axial direction of the rail unit under the driving of the rotating unit, so that the light emitted by the monochromatic light unit 101 to the same area or the same plant can irradiate the same area or the same plant at different incident angles.
For another example, when the rail unit makes the monochromatic light unit 101 reciprocate or rotate longitudinally along a plane (e.g. a horizontal plane), the direction pointed by the monochromatic light unit 101 may form a certain angle with the horizontal plane, and at the same time, the monochromatic light unit 101 may be driven by the rotation unit to perform horizontal scanning with the rotation unit as a center of a circle, so that the light emitted by the monochromatic light unit 101 into the same area or the same plant may irradiate the same area or the same plant at different incident angles
Preferably, the number of the moving parts 2 may be plural. Preferably, at least two moving parts 2 can move in opposite directions in the same plane or different planes. By means of the arrangement mode, the guide rail units of the at least two moving parts 2 can drive the corresponding monochromatic light lamp units 101 to irradiate different sides of the plants, so that the plants can be irradiated from different directions or sides, and irradiation dead angles of illumination can be further reduced.
For example, in the case where the illumination section 1 moves in a plane (for example, a horizontal reciprocating longitudinal movement or a horizontal rotational movement) along with the movement section 2, the monochromatic light lamp units 101 corresponding to the different movement sections 2 may move toward each other or away from each other. Preferably, the illumination section 1 is capable of arranging the monochromatic light units 101 in multiple directions according to the plant growth requirement so as to achieve the optimal illumination environment required by the plant in terms of illumination intensity, illumination direction, spectral composition and the like.
Preferably, at least two illumination sections 1 may be connected to the rail in a fixed manner (i.e. the direction of the outgoing light remains unchanged), while the rail rotates at a fixed point in the animal and plant area, while the two rails connected to the illumination sections 1 are in opposite directions.
Particularly preferably, the illumination portion 1 is connected to the guide rail unit through a rotation unit, so that the illumination portion 1 can rotate at least around the axial direction of the guide rail to adjust the angle of the outgoing light emitted to the animals and plants, so as to reduce the irradiation dead angle of the illumination portion 1.
Preferably, a single or a small number of light sources provide illumination to the animals and plants in a scanning manner. Preferably, the rail unit is movable in a circular motion. Preferably, the rail unit is movable in a zigzag shape. Preferably, the location of the illumination portion 1 may also be located on or near the ground. Preferably, the manner of large-scale illumination of a single light source or a small number of light sources may include: the light source performs scanning in a mobile scanning or fixed (non-mobile) manner.
Preferably, the illumination section 1 can make the illumination intensity of the distal end and the proximal end of the rail unit uniform or approximately uniform at the time of the moving scan.
Preferably, at least two illumination portions 1 can be driven by the moving portion 2 to realize opposite scanning. Preferably, the illumination section 1 itself may also be pitch and/or roll enabled in cooperation with the movement section 2.
Preferably, the outgoing light of the illumination section 1 may also be designed by light distribution such that the outgoing light is not in a circular band shape, but in a circular shape, a rectangular shape, or the like, for example. For example, the same light source is provided with an asymmetric lens, and then the near, middle and far three areas of the area where the plants are located can be managed; after the different light sources are matched with the asymmetric lenses, the near, middle and far areas of the area where the plants are can be divided into three areas.
By this arrangement, compared with a uniform static light source, the illumination part 1 with narrow band and high light intensity dynamically scans the plants and the like by the moving part 2 in a dynamic moving (such as translation, rotation, lifting and other moving modes), so that the illumination dead angles of the animals and the plants irradiated by light rays are less; at the same time, the light intensity and the total energy of the light obtained by the plant in the unit area with more leaves on the macro scale are obviously improved, cilia on the surface of the plant leaves on the micro scale are also reduced to be shielded, and the photoreceptors on the leaf surfaces and the back sides of the leaves can have higher probability of obtaining light to obtain more opportunities for development. In addition, the dynamic light source does not require a complicated light emitting structure compared to the static light source, and thus the cost of the illumination section 1 is lower.
According to a preferred embodiment, the illumination portion 1 further includes a light feedback analysis unit 102, where the light feedback analysis unit 102 includes at least a light-emitting board subunit 102a and a light sensor disposed on a light-receiving surface of the light-emitting board subunit 102 a. In the case that the light receiving surface of the light emitting board subunit 102a is coated with fluorescent powder, the light emitting board subunit 102a is configured to be placed on the light receiving surface side of the plant root, so that the light generated by the illumination portion 1 and/or leaked by natural light passing through the plant leaves is fully utilized to excite the fluorescent powder on the light receiving surface side of the light emitting board subunit 102a to emit light required by the plant, and the light can be irradiated to the plant.
Particularly preferably, the system (device) further comprises a light-emitting board subunit 102a arranged above the plant root, and the light-emitting board subunit is configured to create a dark environment for the plant root, and at the same time, the illumination part 1 and/or natural light passes through the light leaked from the plant leaf to excite the fluorescent powder to emit light required by the plant, and reflect the light to the back of the plant leaf. This is because not only the side of the plant leaf that is remote from the ground has photoreceptors, but also the side of the plant that is close to the ground has photoreceptors. Therefore, the technical scheme of the invention sufficiently utilizes the light leaked from the blades to excite the fluorescent powder to emit the light required by plants, and the light leaked from between the blades and the branches of the plants is reflected into the mid-air again in a back reflection mode through the luminescent plate which is positioned above the roots of the plants and is coated with the fluorescent powder, so that the light reflected back into the mid-air again can be absorbed and utilized by a light receptor on the side facing the ground with the blades of the plants. By the arrangement mode, the light missed by the plants can be reused through the luminescent plate which is positioned above the roots of the plants and is coated with the fluorescent powder, and the utilization rate of the plants (or animals) to the dynamic light source is improved.
According to a preferred embodiment, the control unit 3 can configure the scanning time intervals of different monochromatic lights and the sequencing of the monochromatic light scans as matched to the plant growth based on the actual growth requirements of the different plants. For example, the red and blue alternating intervals may be one hour, i.e., after the red unit is turned on to provide one hour of red illumination, the red unit is turned off and the blue unit is turned on to provide one hour of blue illumination. For another example, red light and blue light may be turned on or off simultaneously at intervals required by the plant based on the lighting requirements of the plant.
The time distribution of light is the distribution of the same light quality and light intensity combination on a light period time axis, and is mainly reflected on the difference of light supply modes. Furthermore, there are related studies that, on the basis of equal power consumption, red and blue light treatments (i.e., red and blue light alternate illumination) of different frequencies are provided. Compared with the mode of simultaneously supplying red and blue light with different frequencies, the mode of alternately supplying red and blue light with different frequencies has positive influence on plant growth and quality. For example, on an equal energy consumption basis, alternating red and blue light once in sixteen hours of light period is beneficial for accumulation of lettuce overground biomass, soluble sugars and crude proteins; the red light and the blue light alternate four times are beneficial to the accumulation of vitamin C and the metabolism of nitrate in lettuce.
On the basis of equal energy consumption, the red light and the blue light alternate for one time in the same light period are beneficial to accumulation of lettuce overground biomass, soluble sugar and crude protein; the red light and the blue light are alternated four times, which is beneficial to the accumulation of vitamin C in lettuce and the metabolism of nitrate), the red light unit and the blue light unit of the illumination part 1 can alternately supply light with a certain frequency based on the illumination requirement of plants.
Particularly preferably, the control unit 3 can control the monochromatic light lamp units 101 of the illumination unit 1 to supply monochromatic light of different frequencies to the area where the plants are located at a certain alternating interval and alternating frequency. For example, in one light cycle (such as one day), the control part 3 may configure the monochromatic light unit to provide an alternating frequency of different monochromatic lights matched with the plant growth requirement according to different kinds of plants, and a light supply time of the single monochromatic light. Preferably, the alternating frequency is the number of times that monochromatic light of different frequencies alternates within the same light period (e.g. one day). Preferably, the light supply time of the single red light and the light supply time of the single blue light may be the same or different.
According to a preferred embodiment, the light feedback analysis unit 102 further comprises a light analysis statistics subunit 102b. The light analysis and statistics subunit 102b can record at least the photon number captured by the light receiving surface side of the light emitting board subunit 102a and/or the energy excited by the fluorescent powder by using the light sensor, and can analyze and obtain growth vigor information of the plant based on the photon number and/or the energy excited by the fluorescent powder, and can send the photon number and/or the energy excited by the fluorescent powder to the control part 3 so that the control part 3 can adjust illumination provided to the plant.
Preferably, the growth vigor information includes, but is not limited to: growth of plant leaves.
According to a preferred embodiment, the control section 3 module further comprises a database formulation unit 301. In case the database recipe unit 301 is able to obtain the energy by which the phosphor sent by the light analysis statistics subunit 102b is excited, the database recipe unit 301 is configured to form and/or update a light meal database matching the illumination requirements of the plant based on the energy by which the phosphor is excited.
The person skilled in the art will easily form and/or update a light meal database matching the lighting requirements of each plant based on the light requirements of said plant in each plant's species, growth phase (e.g. seedling phase, quality formation phase and quality accumulation phase etc.). Since the irradiation time length and illumination intensity database of the seedling stage, the quality formation stage and the quality accumulation stage are also easily formed and updated by the skilled person according to the energy of the excited fluorescent powder, the construction of the photo-dining database is not repeated here.
According to a preferred embodiment, the light receiving surface of the light emitting panel subunit 102a includes a first region. The concentration of the fluorescent powder in the first area can gradually decrease or increase along the radial direction of the plant stem with the plant stem as the center, so that the light analysis and statistics subunit 102b can obtain the growth condition of the plant leaf at least based on the change analysis of the photon quantity captured by one side of the light receiving surface of the light emitting plate subunit 102a or the energy excited by the fluorescent powder, and then can analyze and obtain factors influencing the plant growth to optimize the light meal database.
For example, since the concentration of the phosphor in the first region is decreased radially outward along the stem of the plant centering around the stem of the plant, it may be divided into a first annular band, a second annular band, a third annular band, and so on. Preferably, the first endless belt, the second endless belt and the third endless belt may all be centered on the plant. Preferably, the width of each endless belt is uniform. Preferably, each of the endless belts may be centered on the plant. Thus, when the incident angle of the light emitted from the monochromatic light unit 101 to the plant changes, the light analysis statistics subunit 102b integrated with or disposed on the light receiving surface of the light emitting board subunit 102a can determine or determine the specific growth status of the plant leaves (for example, the leaves at the top are rare, or the leaves near the root are rare, or some or all of the leaves at one side are less than the normal level of the plant) by the photons received from the plant leaves by the different annular bands.
For example, when the top leaf of the plant is rare or less than the normal level and the rest leaves grow normally, when the monochromatic light unit is incident on the plant at a certain inclination angle (for example, the incident light is forty-five degrees from the horizontal plane), the omission from the top of the plant gradually moves from the right side to the left side of the bottom of the plant, and at this time, the concentration of the fluorescent powder in the first area is inconsistent, that is, the concentration of the fluorescent powder in the first to third annular bands gradually decreases, so that the light analysis statistics subunit 102b integrated or disposed in the first area of the light emitting plate subunit 102a can identify that the omitted light is from the top or bottom of the plant.
Particularly preferably, the light analysis statistics subunit 102b is capable of determining from which part of the plant the missing light is incident or missing into the first region from the trend of the energy excited by the phosphor in each of the annular bands during the movement of the missing light within the first region.
For example, when the light analysis statistics subunit 102b recognizes or derives that the missing light moves from the third endless belt (on the right side of the plant) to the second endless belt (on the right side of the plant) by recording the number of acquired photons, the light analysis statistics subunit 102b or the control section 3 judges that the missing light comes from the top of the plant. The ray analysis statistics subunit 102b may also determine that a missing ray is from the top of the plant based on the increasing energy that is stimulated by the missing ray to move from the third annular band (to the right of the plant) to the second annular band (to the right of the plant). For example, when the light analysis statistics subunit 102b recognizes or derives that the missing light moves from the second endless belt (on the right side of the plant) to the first endless belt (on the left side of the plant) by recording the number of acquired photons, the light analysis statistics subunit 102b or the control section 3 judges that the missing light comes from the bottom of the plant. The ray analysis statistics subunit 102b may also determine that the missing ray is from the top of the plant based on the energy that is excited during the movement of the missing ray from the second endless belt (on the right side of the plant) to the first endless belt (on the right side of the plant) gradually increasing and decreasing.
As another example, when the number of leaves on the left of the plant is significantly less than the number of leaves on the right of the plant, when the light analysis statistics subunit 102b recognizes or records that the energy of the missing light excited from the third annular band (on the left of the plant) to the first annular band gradually increases, and either none of the excitation energy (on the right of the plant) or only a portion of the phosphor of the first annular band (on the right of the plant) is excited, then it is determined that the overall leaf growth (on the left of the plant) is significantly lower than the normal level for that type of plant.
For another example, when (the whole leaf of the plant is below the normal level of the plant), and the light analysis statistics subunit 102b identifies or records that the energy excited by the missing light from the third annular band (on the left side of the plant) to the third annular band (on the right side of the plant) is in a trend of increasing and then decreasing, and the average energy excited by the missing light can be higher than the average energy of the fluorescent powder in the first area excited by the missing light when the normal growth level of the plant (leaf) is reached, then the whole leaf growth condition (of the plant) is determined to be significantly lower than the normal level of the plant.
At the same time, the light analysis and statistics subunit 102b can send the trend of the energy excited by the phosphor in each annular band or the determination result to the control unit 3 during the movement of the light omitted from the plant in the first region. Particularly preferably, the control section 3 is capable of analyzing the situation specifically causing the poor (foliar) growth of the type of plant based on the change trend or the determination result of the energy excited by the acquired phosphor and comparing with the historical growth situation of the plant.
For example, if the leaf growth of the same side of the plant is sparse or lower than the normal level of the plant for a long period of time, the control section 3 determines that the cause of the adverse growth of the leaf of the plant may be due to the excessively high temperature of the air corresponding to the side of the plant in the plant factory or in the greenhouse or other plants on the side blocking the incident light.
If the control part 3 derives that the leaf growth at the bottom of the plant is lower than the normal level, the control part 3 decides that the cause of this situation may be that the bottom of the plant is not ventilated smoothly resulting in a concentration of carbon dioxide lower than the normal demand of the plant and the leaf growth at the bottom of the plant is significantly lower than the average level of the plant.
If the control part 3 derives that the leaf growth of the plant as a whole is significantly lower than the normal level, the control part 3 decides that this may be due to the fact that the water supply at the bottom of the plant is too abundant or that the fertilizer applied exceeds the normal demands of the plant, so that the control part 3 can be made to acquire this data to optimize other elements of the plant, such as carbon dioxide concentration, indoor ventilation, indoor temperature, supply of fertilizer adapted to the plant demands, etc. In short, the control part 3 can further influence other adverse factors of plant growth by the energy excited by the fluorescent powder in the first area acquired by the light analysis and statistics subunit 102b, and store the acquired data so as to optimize each element related to plant planting in the future plant planting process, thereby improving the yield of plants while reducing the power consumption of the system.
Preferably, the light receiving area of the light analysis statistics subunit 102b may be a first area.
Preferably, the first region may be circular.
Preferably, the radius of the first area can be flexibly set according to practical requirements, for example, the radius is set to be the maximum length of shadow generated by the plant due to light irradiation when the monochromatic light unit irradiates the plant at an incidence angle of forty-five degrees.
According to a preferred embodiment, the light receiving surface of the light emitting panel subunit 102a further comprises a second area, wherein the fluorescent powder of the second area is coated on the light receiving surface of the light emitting panel subunit 102a in the second area in a manner of same concentration, so that the fluorescent powder of the second area can be directly excited by the light emitted by the monochromatic light lamp unit 101 and/or the natural light which is not blocked by plants to generate the light which can be used for plant growth, and the side of the illumination portion 1 facing the plants can be coated with the fluorescent powder, so that the fluorescent powder on the illumination portion 1 can be excited again by the light emitted from the light emitting panel subunit 102a to the illumination portion 1 to generate the light which is emitted to the plants.
Preferably, the second region is other regions of the light receiving surface of the light emitting panel subunit 102a except the first sub-region.
Preferably, the second region may include a gap between plants and a region where no plants are planted, which is irradiated by the mono-color lamp unit 101. By this arrangement, the light emitted from the illumination unit 1 to the gaps between plants or the plant-free areas can be recycled by the second area of the light-emitting panel subunit 102a, so that the light utilization rate of the illumination unit 1 of the system can be improved.
Preferably, the side of the illumination portion 1 facing the plants can be coated with a phosphor so that the phosphor on the illumination portion 1 can be re-excited with the light emitted from the light emitting panel subunit 102a toward the illumination portion 1 to generate the light toward the plants. By this arrangement, the side of the mono-color lamp unit 101 facing the plant can be coated with phosphor so that the phosphor on the mono-color lamp unit 101 can be re-excited with the light emitted from the light emitting panel sub-unit 102a toward the mono-color lamp unit 101 to generate the light toward the plant.
According to a preferred embodiment, a dynamic light source device includes: an image acquisition section 4 configured to be capable of acquiring at least an image and/or video of an animal and/or plant in a specified area and transmitting the image and/or video to the control section 3.
The control part 3 can analyze and identify basic data information of the animals and/or plants according to the images and/or videos of the animals and/or plants acquired by the image acquisition part 4, and control the illumination part 1 to provide the animals and/or plants with light meal conforming to the requirement of the basic data information according to the basic data information.
Preferably, the image capturing section 4 includes at least a camera or other device capable of capturing images and/or video. Preferably, the image acquisition section 4 may transmit the photographed image and/or video of the animal and/or plant to the control section 3.
Preferably, the control part 3 is capable of sending control signals to the illumination part for adjusting the light meals that can be provided by the lighting units within the illumination part.
Preferably, the designated area may be a physical building for growing plants, such as a greenhouse. Preferably, the designated area may also be a physical building for the farmed animals, such as a chicken house. Particularly preferably, the animals and plants can be cultivated or grown separately and relatively independently. Preferably, the designated area may be a fully enclosed area, such as a farming or planting area relying solely on artificial light sources. Preferably, the designated area may be an area which may also be semi-open or open air, such as a farming or planting area which relies at least in part on solar illumination. Particularly preferably, plants of the same type can be grown in one designated area. Preferably, the single image pickup section 4 may correspond to only one designated area.
Preferably, the plurality of image pickup sections 4 may correspond to one designated area. Preferably, one or more camera devices may be provided in the same designated area. Particularly preferably, the same designated area can be used for planting/breeding the same class of plants/animals. Preferably, the size, shape and area of the same designated area can be flexibly set according to actual requirements.
Preferably, the illumination section is capable of acquiring a control signal from the control section 3 in order to adjust the lighting units in the illumination section accordingly in accordance with the control signal.
Preferably, the above basic data information may include, but is not limited to: the name of the animal and/or plant, the type (e.g., whether it is a positive or negative plant), the stage of growth, etc.
Preferably, the growth phase for plants can be divided into: seedling stage, maturation stage, flowering stage, aging stage and withering stage; for animals, the growth stage can be divided into early childhood, late childhood, sub-adulthood and adulthood, or can be divided directly into age groups, such as three-week-old chicks).
Preferably, the control part 3 may identify the image and/or video of the animal and/or plant using an artificial intelligence based video or image identification technique. Since the technology of identifying animals or plants based on artificial intelligence video or image identification technology in the prior art is mature, and thus a person skilled in the art can easily obtain the technology, the technology of identifying images and/or videos will not be described in detail herein. Preferably, the control section 3 may also use other image and/or video recognition techniques.
For example, the control part 3 may analyze that the captured image and/or video contains the name of an animal and/or plant, the kind (e.g. belonging to a living plant or a living plant) and the growth stage of the plant (or animal), then the control part 3 searches the database provided or integrated in the control part 3 for data information such as light saturation points and light compensation points related to the growth of the plant (and/or animal) located under the basic data information, preferences of the required spectrum (e.g. high light demand in a certain specific spectral range) and the like, and then the control part 3 controls one or more lighting units in the lighting part to provide a light meal corresponding to the animal and/or plant demand in the basic data information to the plant and/or animal in the specific area according to the data information.
