Description

Multi-section periodic light-emitting equipment for agricultural illumination and illumination method
Technical Field
The invention relates to the technical field of plant cultivation, in particular to multi-section periodic light-emitting equipment for agricultural illumination and an illumination method.
Background
Nowadays, the types of gardening facilities mainly include plastic greenhouses, solar greenhouses, multi-span greenhouses, and plant factories, etc., according to facility conditions and the level of environmental factor control in the facilities. The artificial light plant factory is internationally recognized as the highest stage of facility agriculture and is a technology-intensive facility form, and the core technology of the artificial light plant factory comprises a soilless culture technology, an LED lighting technology and an intelligent control technology. The artificial light plant factory has the advantages of full sealing, low requirement on the surrounding environment, shortened plant harvesting period, water and fertilizer saving, no agricultural production, no waste discharge, etc.
Light is used as an important physical environment factor and plays a key role in regulating and controlling the growth and development and the substance metabolism of plants. It has become a common consensus in the industry that "one of the main features of plant factories is the fully artificial light source and the realization of intelligent regulation of light environment".
CN110418571A discloses an illumination device for plant cultivation, or plant cultivation equipment or a plant cultivation method using the same, which provides artificial light suitable for increasing harvest time. A plant cultivation illumination device for illuminating artificial light from a side of a plant toward a plant to be illuminated, the plant cultivation illumination device comprising an LED circuit having a plurality of LED elements for generating the artificial light; and an LED driving circuit that supplies an LED driving current to the pair of LED circuits, wherein the LED driving current has a 1 st period in which a current value is large and a 2 nd period in which a current value is small or no current flows, and the LED driving current periodically changes, and the artificial light whose intensity periodically changes is irradiated to the plant to be irradiated with the artificial light based on the LED driving current whose current value periodically changes.
CN107439242A discloses a control method for shortening the growth cycle of plants, which is characterized in that the method comprises the following steps: step one, a control device for shortening the growth cycle of plants is adopted to provide light sources for the plants; the surface light density of the plant is 2000-6000 Lux, and the method can provide light similar to a sunlight waveband, can also improve light of a waveband required by the plant and promote the growth of the plant.
When plants are cultivated in an existing plant factory, a plane framework and a three-dimensional framework are usually adopted for a plant cultivation frame, the plane framework occupies a large amount of space, so that effective space above the plane framework cannot be fully utilized, meanwhile, a large amount of light supplementing equipment for assisting plant growth is usually matched based on the plane framework, the production cost is undoubtedly increased by the large amount of light supplementing equipment, and in order to solve the problem, the movable light supplementing equipment is utilized in the prior art, but the movable light supplementing equipment cannot ensure that plants at various plant positions in a plant cultivation area can receive light rays with proper proportion and intensity and uniform illumination; for the three-dimensional structure, although the space utilization rate can be effectively increased, when the three-dimensional structure is matched with corresponding light supplement equipment for irradiation, a means that light sources are arranged on each planting layer or the light supplement equipment can move in the vertical direction is arranged on the basis of the three-dimensional structure is not used, but the problems that light irradiation has an illumination blind area and the light irradiation provided by the light supplement equipment is not uniform exist. Secondly, when the light supplement device is used for growing and irradiating plants, the light sources are usually designed in a mode that the light sources with different emission wavelengths or light-emitting colors are combined according to a certain gap and can be independently driven through electric power, but the mode that in actual irradiation, the actual illumination which can be received by various planting positions is different based on the distance difference between the various planting positions and the light sources when the light sources with different emission wavelengths are combined and irradiated is ignored, so that the light source arrangement method adopting a similar equidistant mode cannot meet the requirements of the plants at different positions on light, namely, the various planting positions cannot receive the light with effective uniformity, proper intensity and reasonable proportion. Thus, there remains a need in the art for at least one or several aspects of improvement.
Furthermore, on the one hand, due to the differences in understanding to those skilled in the art; on the other hand, as the inventor studies a lot of documents and patents while making the present invention, but the space is not detailed to list all the details and contents, however, this invention doesn't have these prior art features, but this invention has all the features of the prior art, and the applicant reserves the right to add related prior art in the background art.

Detailed Description
The following detailed description is made with reference to the accompanying drawings.
In the description of the present invention, it is to be understood that "first direction" refers to a direction parallel to the ground or the X axis, and "second direction" refers to a direction perpendicular to the ground or parallel to the Y axis.
The invention provides multi-section periodic lighting equipment and a lighting method for agricultural lighting, which can be applied to plant factories. To this end, the invention also provides a plant factory, which at least comprises a plurality of cultivation devices 1 arranged in the plant factory for bearing plants for plant cultivation and a management system 2 capable of adjusting the cultivation environment of the plant factory in real time at least based on the growth state of the plants and the growth environment thereof.
According to a preferred embodiment, the cultivation device 1 in a plant factory comprises at least a plant cultivation frame 10, the plant cultivation frame 10 may comprise a shaft body 101, at least one first rail 102 distributed on the circumferential outer side surface of the shaft body 101 in a spirally surrounding manner, and a plurality of second rails 103 distributed on the circumferential outer side surface of the shaft body 101 and arranged along the axial gap of the shaft body 101. Preferably, the end of the shaft 101 near the ground is defined as a ground proximal end 101a, and the end thereof away from the ground is defined as a ground distal end 101b.
According to a preferred embodiment, as shown in fig. 1, the first track 102 is configured as a spiral track extending in the axial direction of the shaft body 101 and formed in a manner to spirally spread in a substantially circular shape starting from the axis of the shaft body 101. Preferably, the shape having the spiral diffusion may include a regular spiral and/or an irregular spiral as long as it is satisfied that each point on the curve extending in the prescribed direction takes a posture in which the perpendicular distance from the shaft body 101 gradually increases or decreases.
According to a preferred embodiment, the first track 102 extends axially around the shaft 101 to form a plurality of cultivation layers with different layer spacing. The range of at least one cultivation layer can be defined as a complete plane, a half plane or other selection formed by the first rail 102 surrounding the shaft 101, which mainly depends on the planting requirement of each cultivation layer, because the plants cultivated by each cultivation layer can be the same or different, and the plants can have at least some difference in appearance based on the growth forms that different plants may have in different growth cycles, and the layer spacing between each cultivation layer and the range defined by the cultivation layer are adjusted based on the type of the plant to be planted in order to adapt to the growth characteristics and growth performance of different plants to promote their growth and development and thus make them show the most excellent growth state. Preferably, not only the plants planted on the respective cultivation layers are maintained in an excellent growth state, but also the limited space between the respective cultivation layers is fully utilized based on the design structure of the first rail 102.
According to a preferred embodiment, the first track 102 is configured to extend along the distal end 101b of the shaft body 101 towards its proximal end 101a in a manner shaped around the shaft body 101 with the shaft body 101 as a centre of rotation, and the first track 102 assumes a geometrically stepped and/or proportionally increasing attitude around the radius or perpendicular distance thereof from the shaft body 101 in a direction along the distal end 101b of the shaft body 101 towards its proximal end 101 a. Alternatively, at least a portion of the first track 102 on the side closer to the distal end 101b may have a smaller radius of curvature or a shorter perpendicular distance from the shaft body 101. While at least a portion of the first track 102 near the ground-near end 101a has a larger curve-surrounding radius or a longer vertical distance from the shaft body 101, which allows for the plants at the ground-far end 101b to be closer to the light source, which receives more or stronger light than the plants at the bottom end. While the plants at the proximal end 101a are further from the light source and receive less or weaker light than the top plants. Preferably, either fancy plants or plants with long lighting periods can be planted in at least a portion of the orbit relatively close to the remote ground end 101b, or plants with smaller sizes can be planted around a radius based on a smaller curve; while plants with weak light resistance or short light cycle are planted in at least a portion of the orbit relatively close to the ground-near end 101a, or plants with larger shape are planted around a radius based on a larger curve. Further, the inner side of the first rail 102 is configured as a first channel 1020 extending along the surrounding direction thereof and matching the shape of the first rail 102, the first channel 1020 being configured for carrying, cultivating plants and transporting nutrient solution.
According to a preferred embodiment, as shown in fig. 3, the circumferential outer side surface of the shaft body 101 may be provided with a plurality of first rails 102. Specifically, the plurality of first tracks 102 may be disposed on the circumferential outer side surface of the shaft body 101 in such a manner as to spirally wrap around each other in the first direction and/or the second direction with a certain clearance. Alternatively, the gaps between the first rails 102 in the first direction and/or the second direction may be the same or different, depending on the type of plants being cultivated by the plant cultivation shelf 10, and the gaps between the first rails 102 are adjusted to allow the plants at each planting point in each cultivation layer on the first rails 102 to receive suitable light and grow to the maximum extent according to the growth characteristics thereof, in order to adapt to the growth forms of different plants or the requirements for light, as shown in fig. 6. Preferably, the first tracks 102 are arranged in a manner that the whole volume of the first tracks 102 shows geometric progression and/or equal proportion increase in a direction away from the shaft body 101 along the first direction by taking the shaft body 101 as a center, or the curve radius of at least part of the tracks of the first tracks 102 in the same plane shows geometric progression and/or equal proportion increase in posture. And the whole volume of the first rail 102 close to the shaft 101 is smaller than that of the first rail 102 far from the shaft 101, that is, when looking down along the second direction, the cultivation layers constructed by the first rails 102 are in a staggered posture, as shown in fig. 6. Preferably, the plants on different cultivation layers of the first tracks 102 staggered with each other are exposed to the illumination to the maximum extent based on the phototaxis of the plants during growth, and receive illumination with reasonable proportion and appropriate intensity, so that the excellent growth state such as vertical upward growth can be maintained to the maximum extent.
According to a preferred embodiment, at least part of the circumferential outer surface of the shaft body 101 is provided with a substantially annular second illumination portion 21b. The distal end 101b of the shaft body 101 is provided with at least one movable substantially linear first illumination portion 21a. Specifically, the first illumination portion 21a may be foldable, which considers that when the plant is irradiated by natural light or sunlight without additional supplementary lighting device, the first illumination portion 21a located above the first track 102 may shield at least a part of the plant below the first illumination portion, so as to prevent a part of the sunlight from irradiating the surface of the shielded plant, and thus the plant may show slow growth and the like compared with other plants, and therefore the first illumination portion 21a may be folded towards the direction close to the shaft body 101 manually or based on an external driving manner, so as to reduce the blockage of the illumination light, and thus a plurality of plants on the first track 102 may receive uniform light to perform normal growth and development. Or the at least one first illumination part 21a is folded towards the direction close to the shaft body 101 manually or based on an external autonomous driving mode, namely the first illumination part 21a and the shaft body 101 are in a parallel state, so that the influence on the growth and development of plants due to the fact that the first illumination part 21a forms irradiation obstruction on partial light rays is eliminated.
According to a preferred embodiment, the second illumination portion 21b can additionally illuminate the plants on the spiral first track 102 in such a way that a substantially annular light is emitted radially outward from the shaft 101. Specifically, when the plants thereunder are subjected to growth irradiation by the first illumination portion 21a above the first rail 102, besides the ideal state, the partial plants inevitably cause light blocking to each other during the growth process, for example, the plants relatively close to the top cause light blocking to the plants thereunder; or due to the rotation and/or swing irradiation of the first illumination part 21a, when the plant on the first track 102 is irradiated, at least a part of the illumination blind area exists, for example, at least a part of the first track 102 relatively close to the shaft body 101 may be blocked by the first track 102 at the periphery thereof. Therefore, in this case, at least a part of the plants cannot receive effective light by the leaves thereof to perform photosynthesis required for growth and development, so that the second illumination unit 21b can be used to supplement light to the plants on the first rail 102 from the opposite inner side in cooperation with the first illumination unit 21a, that is, to illuminate the plants from a plurality of angles in cooperation with the second illumination unit 21b when the ideal light coverage cannot be satisfied by the first illumination unit 21a. Preferably, the illumination intensities of the second illumination portion 21b and the first illumination portion 21a may be the same or different from each other in consideration of the phototaxis of plant growth, in order to allow the plants on the respective cultivation layers to grow in the most excellent growth posture, and in addition to providing good quality, to make full use of the respective first tracks 102 and the cultivation spaces on the cultivation layers thereof. Further, the ratio of the light intensities of the second illumination unit 21b to the first illumination unit 21a can be adjusted according to the real-time growth state of the plants on each cultivation layer. Specifically, the real-time growth state of the plant can be detected by, for example, an image pickup device. For example, when the plant on the first track 102 assumes a growing posture in which it is bent toward the shaft body 101, the ratio of the illumination intensities of the first and second illuminating parts 21a and 21b may be appropriately increased to keep the plant in a vertically growing posture as much as possible.
According to a preferred embodiment, the first illumination portion 21a can illuminate the plant on the first rail 102 in a state of being substantially parallel to the ground. Or the plant on the first rail 102 is subjected to growing irradiation in a state of being parallel to a generatrix of a substantially conical structure formed by the first rail 102 being wound, as shown in fig. 9. Preferably, the first illumination portion 21a is rotatable around the shaft 101 by a rotating component disposed at the distal end 101b of the shaft 101 to provide a substantially truncated cone-shaped and/or conical light coverage area for the plants on the first track 102. The specific configuration of the rotating means is not limited at all, and a configuration that enables the second illumination section 21b to rotate around the shaft body 101, which is commonly used in the related art, may be adopted. Preferably, compared to the static light source with a larger light coverage area in the prior art, the first illumination part 21a in the embodiment of the present invention is configured as a dynamically movable linear light source, so that the light emitted by the first illumination part 21a is more concentrated to increase the corresponding illumination intensity, and the corresponding dead zone of illumination is greatly reduced by the dynamic light source, so that more blades can receive light, and the light blocking effect of cilia on the surface of the blade is greatly reduced, so that other parts of the blade, such as the light sensing part on the back side of the blade, can also be irradiated by more light, which is more favorable for the uniform growth of plants.
According to a preferred embodiment, when the first lighting part 21a illuminates the plant located therebelow, its specific pose is manually or externally driven, and for external driving, its specific pose adjustment is based on monitoring of the plant growth state or plant growth environment by external equipment. Further, the monitoring of the plant growth state can be completed by a method of detecting the area of plant leaves and the plant growth height through a camera device, which is commonly used in the prior art; to pairThe plant growth environment can be monitored by using sensors to detect air humidity, temperature, illumination intensity, CO in the plant growth area 2 Or O 2 Concentration, etc.
Preferably, after the image of the growth state of the plant on the cultivation layer at the upper end of the first track 102 is captured by the image capturing device, the image is analyzed by the external control device or the central control device and compared with the standard data in the database, when, for example, the area of the plant leaf reaches a preset growth threshold, the external control device or the central control device can drive the first illumination part 21a to unfold in a direction away from the shaft body 101, and at this time, the plant on the lower cultivation layer may not meet the corresponding growth threshold, and the illumination intensity is reduced due to the increase of the distance between the tail end of the first illumination part 21a and the lower cultivation layer, so that the illumination intensity of the light emitting element on the side of the first illumination part 21a away from the shaft body 101 can be enhanced by external driving and the illumination intensity of the light emitting elements of other sections of the first illumination part 21a can be appropriately adjusted to adapt to the change of the illumination intensity caused by the change of the light distance.
Or, after the image of the plant growth state on at least part of the cultivation layer of the first track 102 is captured by the camera device, the image is analyzed by the external control device or the central control device and compared with the standard data in the database, when, for example, the area of the plant leaf reaches a preset growth threshold, the external control device or the central control device can drive the first illumination part 21a to be folded and/or unfolded in a direction close to and/or away from the shaft body 101, and drive the first illumination part 21a to rotate through the rotating component, and for plants in other areas which do not meet the corresponding growth threshold, the requirement of the plants in the corresponding area for the growth light can be met by adjusting the light intensity of the light emitting elements in different sections of the first illumination part 21a based on the external drive.
Preferably, when the sensor detects CO located in at least a portion of the area of the first track 102 2 Concentration, O 2 After the concentration or the concentration ratio, the external control device or the central control device analyzes the numerical value and compares the numerical value with standard data, and when CO is in the condition of concentration or concentration ratio, the numerical value is analyzed by the external control device or the central control device and compared with the standard data 2 The concentration,O 2 When the concentration or concentration ratio thereof reaches a preset threshold, e.g. when CO 2 Concentration below a certain threshold and O 2 When the concentration is higher than a certain threshold or the concentration ratio is higher than a certain threshold, the net photosynthesis of the plants in the area can be considered to be stronger, and then the folding and/or unfolding of the first illumination part 21a can be adjusted based on the driving of the external control device or the central control device, and the first illumination part 21a is driven to rotate by the rotating assembly to reduce the illumination corresponding to the area meeting the preset threshold, and/or enhance the illumination not meeting the preset threshold.
According to a preferred embodiment, the first and second illumination sections 21a and 21b may be formed by combining several independently drivable light emitting modules 210. Specifically, each light emitting module 210 is configured to be formed by combining several light emitting units that can be independently driven and have different emission wavelengths or emission colors. Further, each light emitting module 210 is provided therein with a first light emitting unit 210a, a second light emitting unit 210b, and a third light emitting unit 210c.
Optionally, the first light emitting unit 210a is configured as a red LED light source having an emission wavelength of 620nm to 760 nm. The second light emitting unit 210b is configured as a blue LED light source having an emission wavelength of 400nm to 450 nm. The third light emitting unit 210c is configured as a green LED light source having an emission wavelength of 492nm to 577 nm.
Preferably, the first light emitting unit 210a, the second light emitting unit 210b and the third light emitting unit 210c with different emission wavelengths are independently driven to provide the plants on the first rail 102 with the light required to meet different growth requirements thereof. For example, a blue LED light source having an emission wavelength of 400nm to 450nm may be used to promote the growth of plant leaves and stems, a red LED light source having an emission wavelength of 620nm to 760nm may be used to promote flowering and fruiting in plants, and a green LED light source having an emission wavelength of 492nm to 577nm may be used to delay leaf senescence.
Preferably, a composite light similar to natural light may be compositely formed by simultaneously driving the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c, and the light quality of the composite light may be changed by adjusting the intensity ratio of each light emitting unit to change the irradiation effect on plants so that they can represent the optimal growth state based on an excellent irradiation environment. In particular, the red light fraction can be suitably enhanced to reduce the blue light fraction, not only because an excessively high content of blue light may retard or inhibit plant growth, hinder its synthesis of carbohydrates, etc., but also because blue light is somewhat harmful to the human eye. For example, for some leaf vegetables, the red-blue light ratio required in the seedling stage has a certain requirement, and the red-blue light ratio can be properly adjusted to increase the seedling quality of the corresponding leaf vegetables in the seedling stage and prevent the corresponding leaf vegetables from growing in vain.
According to a preferred embodiment, the plurality of first tracks 102 are configured to extend from the distal end 101b of the shaft body 101 to the proximal end 101a thereof in a manner of being shaped around the shaft body 101 with the shaft body 101 as a rotation center, and the curve of the first tracks 102 in the direction along the distal end 101b of the shaft body 101 to the proximal end 101a thereof presents a geometric progression and/or an equally scaled increasing posture around the radius or the perpendicular distance between the first tracks and the shaft body 101, so that, in order to adapt to the illumination requirement generated based on the design structure of the first tracks 102, the light emitting module 210 formed by a combination of a plurality of light emitting units which can be driven independently and have different emission wavelengths or emission colors in the first illumination part 21a is configured to: the mounting gaps of the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c in each light emitting module 210 are increased or decreased in equal proportion to each other as viewed in the arrangement direction of the substantially linear first illumination portion 21a, as shown in fig. 8. That is, the mounting gap between the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c in the light emitting module 210 relatively close to the shaft body 101 side is larger than the mounting gap between the first light emitting unit 210a, the second light emitting unit 210b, and the third light emitting unit 210c in the light emitting module 210 relatively far from the shaft body 101 side. Preferably, the specific installation gap can be obtained by calculating parameters such as a suitable photon flux and a photon flux density according to a specific design structure of the first track 102 through a formula.
According to a preferred embodiment, the mounting gaps between the light emitting elements in the light emitting modules 210 are different from each other in consideration of the illumination effect of the light quality combination, ratio and intensity of the first illumination portion 21a on the plants on the first rail 102 located therebelow. Specifically, when the light emitting elements with different emission wavelengths are alternately arranged and emit light simultaneously, at least a portion of the light generated by the light emitting elements is overlapped, and similarly, at least a portion of the light generated by the light emitting module 210 composed of the light emitting elements is also overlapped, so that the light in the overlapped region has a higher light quantum flux, and the light in the other non-overlapped region has a lower light quantum flux, and the non-uniform emitted light is not favorable for plant growth, especially corresponding to the spiral multilayer structure of the first track 102 in the present invention.
According to a preferred embodiment, when the first illumination part 21a illuminates the plants on the lower cultivation layers of the first track 102 based on the horizontal posture of the first illumination part, if the plants are illuminated with the same installation gap and illumination intensity, the effective illumination available to the plants on each cultivation layer is different based on the different light distances of the plants on each cultivation layer from the first illumination part 21a in the second direction, and particularly, the illumination which can be received by the plants on the cultivation layer at the bottom of the first track 102 is more limited. Further, since the radius of the first track 102 around the curve in the extending direction from the distal end 101b of the shaft 101 to the proximal end 101a thereof or the vertical distance between the first track 102 and the shaft 101 is in a geometrically-graded and/or proportionally-increased posture, in order to adapt to the change of the radius of the first track 102 around the plant to satisfy the uniform illumination of each cultivation layer, the installation gap between the light emitting elements in the first illuminating part 21a is gradually decreased with the geometrically-graded and/or proportionally-increased radius of the first track 102 around the curve in the extending direction from the distal end 101b of the shaft 101 to the proximal end 101a thereof, that is, at least a part of the plant closer to the distal end 101b of the first track 102 is closer to the first illuminating part 21a, so that the effective illumination which the light emitting elements can receive is stronger, the installation gap between the light emitting elements corresponding to the position is larger, so as to reduce the higher light flux generated by partial overlapping, avoid the plant receiving the stronger light at the position, prevent the light from being excessively intensified, and prevent the light from being wasted and the light emitting elements from being excessively radiated, and the light can be prevented from being excessively.
According to a preferred embodiment, the light intensity of at least a part of the plants irradiated to the far end 101b of the first rail 102 in a composite overlapping manner is reduced when the mounting gap of each light emitting element in the light emitting module 210 of the first illumination part 21a near the shaft body 101 is larger, and the light generated by the light emitting element can be more irradiated to the plants on the rest cultivation layers, for example, the plants on the cultivation layers far away from the far end 101b, so that the proportion of redundant light irradiated to at least a part of the plants on the far end 101b is reduced and the proportion of effective light irradiated to at least a part of the plants on the rest cultivation layers is increased. On the other hand, the mounting gap of each light emitting element in the light emitting module 210 at the tail end of the first illumination portion 21a far away from the shaft body 101 is the smallest, and similarly, at least a part of the plant closer to the ground end 101a of the first rail 102 is farther from the first illumination portion 21a, and the effective illumination that can be received by the plant is weaker, so the mounting gap of each light emitting element corresponding to the position is smaller, so that higher light quantum flux generated by overlapping of partial light rays is increased, composite illumination received by the plant is prevented from being too low, the illumination required by the plant is increased, the utilization rate of the light is increased, the inhibition effect of the too low illumination intensity on the growth of the plant is also avoided, meanwhile, the overlapped light rays generated by each light emitting element are increased based on the radiation diffusion of light, and the dispersion of the light rays is reduced, so that more light rays can be concentrated at the position, thereby providing stronger illumination.
According to a preferred embodiment, the light intensity of at least a part of the plants irradiated to the far end 101b of the first rail 102 in a composite overlapping manner is reduced when the mounting gap of each light emitting element in the light emitting module 210 of the first illumination part 21a near the shaft body 101 is larger, and the light generated by the light emitting element can be more irradiated to the plants on the rest cultivation layers, for example, the plants on the cultivation layers far away from the far end 101b, so that the proportion of redundant light irradiated to at least a part of the plants on the far end 101b is reduced and the proportion of effective light irradiated to at least a part of the plants on the rest cultivation layers is increased. Preferably, when the plant on the first rail 102 is grown and irradiated by adjusting the posture of the first illumination unit 21a based on the arrangement of the mounting gaps of the light emitting elements in the first illumination unit 21a, the variation of the illumination intensity due to the variation of the light distance can be adapted by adjusting the light source ratio and the intensity of the light emitting elements in different sections of the first illumination unit 21a based on the distance between the first illumination unit 21a and the plant on each cultivation layer. For example, when the light module 210 at the tail end of the first illumination portion 21a is close to the plant on the bottom cultivation layer of the first rail 102, the light intensity of each light emitting element in the light module 210 in the area can be correspondingly reduced to provide a suitable illumination intensity, or the ratio of each light emitting element can be appropriately adjusted to provide a suitable light source ratio based on the growth characteristics of the plant on the bottom cultivation layer.
According to a preferred embodiment, the installation manner of the installation gap between the light emitting units in the light emitting modules 210 of the second illumination unit 21b is the same as that of the first illumination unit 21a. Specifically, the mounting gaps between the light emitting units in the light emitting modules 210 of the second lighting unit 21b are sequentially reduced in the direction extending along the distal end 101b toward the proximal end 101a of the shaft body 101. Accordingly, the mounting clearance of each light emitting element in the light emitting module 210 of the second illumination section 21b on the side closer to the distal end 101b in the axial direction of the shaft body 101 is large, and the mounting clearance of each light emitting element in the light emitting module 210 of the second illumination section 21b on the side closer to the proximal end 101a in the axial direction of the shaft body 101 is small.
Preferably, the surrounding radius of the partial track on the side of the first track 102 close to the far end 101b of the shaft 101 is smaller or the partial track is closer to the shaft 101, so that the partial track can receive more or stronger effective light than the partial track below the partial track, and therefore, in order to reduce the overlapped light irradiated to the partial track, reduce the overall irradiation intensity and improve the overall utilization rate of light, the light emitting elements in the light emitting module 210 corresponding to the partial track have a larger installation gap therebetween, and the light generated by the light emitting module 210 can be more irradiated to the plants on the rest of the cultivation layers, so as to reduce the proportion of redundant light irradiated to at least part of the plants on the far end 101b and improve the proportion of effective light irradiated to at least part of the plants on the rest of the cultivation layers.
Preferably, the mounting gap of each light emitting element in the light emitting module 210 of the second illumination portion 21b along the axial direction of the shaft body 101 and on the side close to the ground end 101a thereof is smaller, and similarly, at least a part of the plant closer to the ground end 101a of the first rail 102 is farther from the second illumination portion 21b and can receive weaker effective illumination, so that the mounting gap of each light emitting element corresponding thereto is smaller to increase a higher light quantum flux generated by overlapping of partial light rays, avoid too low composite illumination received by the plant, increase illumination required by the plant to increase the utilization rate of light, and also avoid an inhibition effect on plant growth due to too low illumination intensity, and simultaneously, overlapped light rays generated by each light emitting element are increased based on radiation diffusion of light to reduce the dispersion of light rays so that more light rays can be concentrated at the location to provide stronger illumination. Further, the specific installation gap can be obtained by calculating parameters such as a suitable photon flux and a suitable photon flux density according to the specific design structure of the first rail 102 through a formula.
According to a preferred embodiment, as shown in fig. 2 and 5, a plurality of second tracks 103 having different lengths are distributed on the circumferential outer side surface of the shaft body 101 at intervals along the axial direction thereof. Specifically, the second rail 103 is inclined to the ground approximately at a certain angle. Preferably, the inclined state facilitates the liquid to fall down by gravity. Further, the inner side of the second track 103 is configured as a second channel 1030, the first channel 1020 being configured for carrying the first track 102 and for transporting a nutrient solution. The first track 102 and the second track 103 are coaxially arranged. And the plurality of first rails 102 and the plurality of second rails 103 construct a plurality of planting parts P for plant cultivation on each cultivation layer of the first rails 102 in such a manner that their respective channels intersect with each other, as shown in fig. 6. In particular, the planting parts P on adjacent planting layers are arranged in a staggered manner with a certain gap between each other when viewed from above in the second direction, in order to increase the utilization rate of the planting gaps in the first direction and the second direction.
According to a preferred embodiment, the lengths of the plurality of second tracks 103, viewed from above in the second direction, assume successively increasing postures in a direction along the distal end 101b of the shaft body 101 toward the proximal end 101b, as shown in fig. 2 and 5. Specifically, the length of the second track 103 proximate to the distal end 101b of the shaft body 101 is the shortest, and the length of the second track 103 proximate to the proximal end 101b of the shaft body 101 is the longest. Further, the length difference of the second rails 103 in the axial direction of the shaft body 101 is set according to the structure of the first rail 102. Since the curve surrounding radius of the first track 102 in the direction extending along the distal end 101b of the shaft body 101 toward the proximal end 101a thereof or the vertical distance therebetween from the shaft body 101 is in a geometrically and/or equally proportionally increased posture, the second track 103 relatively close to the distal end 101b needs to carry the first track 102 having a smaller or smaller number of curve surrounding radii, while the second track 103 relatively close to the proximal end 101a needs to carry the first track 102 having a larger or smaller number of curve surrounding radii.
According to a preferred embodiment, a plurality of planting parts P for plant cultivation are constructed on each cultivation layer of the first rail 102 by a plurality of first rails 102 and a plurality of second rails 103 in such a manner that their respective channels intersect each other. Preferably, the gaps between the plurality of planting parts P in each cultivation layer of the first rail 102 may be the same or different, which mainly depends on the type of plants cultivated in each cultivation layer and enables the limited space to be fully utilized, and while adjusting the number of the first rails 102, the distance between the first rails and the distance between the second rails 103, the number of the planting parts P and the distance between the second rails can be adjusted to change the number of the planting parts P and the distance between the planting parts P, so as to fully utilize the cultivation space in each cultivation layer of the first rails 102 and enable the plants in each cultivation layer to receive more light.
According to a preferred embodiment, the invention can be adapted to known hydroponic and/or aeroponic plant cultivation methods. Preferably, in the case of the hydroponics method, when the plants in the plurality of planting parts P formed by the arrangement of the first rail 102 and the second rail 103 are cultivated, the nutrient solution can flow downwards along the first channel 1020 of the first rail 102 due to gravity and wet the roots of the plants when reaching the corresponding planting parts P, so that the plants in each planting part P can absorb the nutrient supplied by the nutrient solution to promote the growth of the plants.
According to a preferred embodiment, as shown in fig. 1 to 6, the shaft body 101 is a plurality of planes perpendicular to the first track 102 and distributed along the axial direction of the shaft body 101, and formed by the first track 102 rotating around the plane, and the planes are circular, elliptical or spiral. Preferably, the inside of the shaft body 101 is configured as a hollow passage 1010 extending in the axial direction thereof. Further, a pipe 1011 for transporting a nutrient solution is disposed in the hollow channel 1010. The outer circumferential surface of the pipe 1011 is formed with a plurality of outlet holes 1012 arranged at intervals along the axial direction thereof, as shown in fig. 7.
According to a preferred embodiment, each lead-out hole 1012 is connected to an end of the second rail 103 extending into the shaft body 101. Preferably, a liquid extraction device of a centrifugal pump or the like may be provided in the pipe 1011 to extract the nutrient solution flowing to the bottom of the pipe 1011 to the top of the pipe 1011 along the extending direction of the pipe 1011, and the nutrient solution can flow into the second channel 1030 of the corresponding second rail 103 through each of the guide holes 1012 and flow downward based on the gravity caused by the inclined state of the second rail 103 when being sucked to each of the guide holes 1012. Further, both ends of the pipe 1011, which are respectively close to the proximal end 101a and the distal end 101b of the shaft body 101, are connected to both ends of the first rail 102 extending into the shaft body 101, so that the nutrient solution flowing along the first channel 1020 of the first rail 102 can finally flow into the pipe 1011, and can flow into the first channel 1020 of the first rail 102 again when being pumped to the top of the pipe 1011, thereby repeating the above-mentioned nutrient solution watering process.
According to a preferred embodiment, the curvature of any one point on the second track 103 having an arc shape is continuously decreased in view of the increase of the distance from the shaft body 101. In other words, the curvature of the second track 103 has a decreasing trend along its extension. Preferably, the nutrient solution flows along the extending direction of the second channel 1030 due to the gravity, during the flowing process, the plants in the top planting part P of the second track 103 are firstly contacted with the nutrient solution, and then the nutrient solution is firstly contacted with the plants in the planting part P below the second track 103, because the curvature of the second track 103 is continuously reduced, the staying time of the nutrient solution in the top planting part P of the second track 103 is longer, because the larger curvature has a certain temporary effect on the flowing of the nutrient solution, so that the contact time of the nutrient solution with the plants in the top planting part P is longer, the effective absorption of the nutrient substance in the nutrient solution by the corresponding plants is increased, and along with the continuous reduction of the curvature in the extending direction of the second track 103, the flowing speed of the nutrient solution is gradually increased, the contact time of the nutrient solution with the plants in the bottom planting part P of the second track 103 is gradually reduced, which considers that the part of the nutrient solution in the top planting part P of the second track 103 can provide the retained nutrient solution due to the temporary reduction of the curvature of the planting part P, the nutrient solution in the bottom planting part P of the second track 103, and the problem that the nutrition solution can be supplied to the root part P, and the root part P can be supplied to supplement the nutrient solution.
According to a preferred embodiment, a phosphor-coated light emitting plate may be further provided near the plant root system in the planting part P, preferably, for example, above the plant roots, to provide a growth environment without light to the plant root system, and the phosphor-coated light emitting plate receives light and is excited to emit light of a certain wavelength while at least a part of the light emitted from the first and/or second illuminating parts 21a and 21b passes through the plant leaves.
According to a preferred embodiment, the fluorescent layer is provided on a luminescent plateAfter the light-emitting powder material is excited and emits light with a certain wavelength and intensity, the light emitted by the light-emitting plate can be detected by the optical detection element to determine the growth state or progress of the plant leaves, for example, the amount of light that can be received and/or transmitted by the leaves in different growth states is different, which reflects to a certain extent the growth cycle of the plant, the current growth rate of the plant, and the like. Preferably, the position of the optical detection element is not limited specifically as long as the light receiving and detecting can be completed, and in this embodiment, for example, the optical detection element can be disposed at the bottom of the cultivation layer above the plant to receive and detect the light emitted by the light-emitting plate below the cultivation layer. Further, the growth condition of the plant is judged by the difference and change of the emitted light, and other parameters such as temperature, moisture and CO in the growth environment of the plant can be further judged according to the growth condition of the plant 2 Concentration, etc. is supplied in sufficient or excessive amounts. Preferably, photosynthesis in plants is accompanied by CO for at least part of the time, for example when the light intensity is constant 2 Increased in concentration and in CO 2 When the concentration reaches a threshold value, CO 2 Concentration has little effect on photosynthesis, but causes respiration to be continuously attenuated, and the net photosynthetic rate of a plant decreases, which affects the growth and development of the plant.
According to a preferred embodiment, different types of plants and their corresponding growth cycles, as well as the types of light required by the different plants in the different growth cycles, the irradiation times and their intensities, etc. can be correlated with each other to build a photo-formulation database suitable for a plant factory, so that suitable growth schemes can be set for the different types of plants on the basis of the photo-formulation database, so that when planting different plants, only the growth schemes correlated therewith need to be invoked. For lettuce, for example, the irradiation light with the intensity of 100% and the duration of 2h is needed in the seedling period; for cauliflower, it requires irradiation light with an intensity of 60% for a period of 2h during the quality-forming period. Preferably, the illumination duration and illumination intensity in different plant growth schemes are customizable, i.e. the light intensity and duration can be combined differently from each other in order to meet the optimal conditions for plant growth. Furthermore, the optical prescription database can keep a continuously updated state according to the change of the data such as the plant species, the environmental parameters and the like, so that the plants planted in the plant factory are correspondingly configured with growth schemes meeting different planting requirements. Preferably, the plant after cultivation in the plant factory is used for subsequent cultivation of other animals.
