[0002] Light is an indispensable and important physical factor in the growth process of any plant from germination to maturity. The lush growth of various plants in nature must rely on the energy provided by sunlight. According to biological theory, light helps to speed up the absorption of various nutrients by chlorophyll in plants, such as water and carbon dioxide, and synthesize more carbohydrates to promote plant growth. The plant lamp technology was born by simulating sunlight. Its important technical core is that it can realize artificial regulation of light. By adjusting the light state of the plant lamp, we can identify the growth status of the plant and specifically control the growth rate of the plant or control the morphology of the plant. It is an important technology in the field of modern plant cultivation.

[0003] The prior art discloses an application number of 202010523570.4, and the name of the patent application is an intelligent adjustment plant light supplement system, which discloses the field of agricultural planting technology. The technical scheme adopted includes a light supplement device, a light intensity detection device and a control system. In the present invention, the height and position of the plant lamp can be flexibly adjusted by a telescopic rod and a movable base respectively. During the growth of the plant, the height of the plant lamp can be adjusted according to the change of the plant height. The light source is always kept at a distance of about 10 cm from the plant, and the light energy utilization rate is the highest at this time; through the cooperation of the linear motion module and the second distance sensor, the photon sensor can always be kept at a distance of less than 6 cm from the plant. The light intensity value detected at this distance is closer to the actual light intensity received by the plant, providing a more accurate basis for the control of the plant lamp; the plant lamp can adjust the irradiation angle by rotation, providing more uniform lighting conditions for plants with higher plant heights, and increasing the photosynthesis rate of the leaves in the lower part of the plant.

[0004] The prior art discloses an application number of 201110162508.8, and the name of the patent application is a plant cultivation intelligent light-filling method and system; it discloses that the light-filling method includes the following steps: (1) light intensity collection; (2) judging whether light-filling is needed, and if light-filling is needed, light-filling is performed in one or a combination of automatic mode light-filling, time-slot mode light-filling, manual mode light-filling, and controlled mode light-filling; the light-filling system includes at least one intelligent light-filling controller, at least one plant light group, and at least one light detector, and the intelligent light-filling controller is connected to the light detector and the plant light group through a bus and a light driving interface. The present invention can perform light-filling according to the different light intensity requirements of different plants, and can also simulate the change of sunlight to perform light-filling in a gradient manner on plants, and has the advantages of flexible system structure and easy expansion.

[0005] The prior art discloses an application number of 202110037490.2, and the name of the patent application is a method and device for implementing a plant light formula supplementary lighting system based on artificial intelligence. The method is to collect plant images; identify and obtain plant species information and growth stage information based on the plant images; retrieve corresponding light ratio data based on the plant species information and the growth stage information; and adjust the light output ratio of the plant lamp based on the light ratio data.

The present invention identifies the growth conditions of different plants at different stages, accurately controls the plant lamp to provide the best supplementary lighting strategy for the plants, meets the different spectral requirements of different plant growth, and maximizes the growth benefits of the plants.

[0006] However, the existing technology still has the following disadvantages: the plants may have diseases and insect pests or dwarf plants, which are not entirely due to insufficient light intensity. The growth period cannot be fully determined by plant images alone. In addition, the existing image shooting and fill-in lighting can only be done from a high altitude. The observation distance for newly sprouted vegetation is far, and later maintenance and adjustment are difficult.

[0007] Therefore, the present invention provides a plant intelligent lighting device that can observe leaf veins and stem thickness and can be installed at a low place. Summary of the invention

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] Reference Figure 1-Figure 8 As shown, this embodiment provides a specific implementation method for a plant intelligent lighting device, including a track system and a control system, wherein the control system is used to control the operation of the track system, wherein the track system includes a plurality of tracks 10 and a sliding support 20 mounted on each track 10, and the track 10 is directly mounted at a height of 50 cm or more from the ground. Figure 1 , Figure 2 shown.

[0034] That is to say, the present invention can be arranged at a low place or a high place, and the fan-shaped bracket 201 arranged above the sliding support 20 can rotate, and the infrared camera 202 and the plant light 205 mounted on the fan-shaped bracket 201 can look up as well as look down. It is not only suitable for the entire growth process of a certain plant, but also when raising seedlings, the low-place design is more practical and more convenient for later maintenance.

[0035] like Figure 3As shown, specifically, the sliding support 20 includes a fan-shaped bracket 201, an infrared camera 202, a stepping motor, a base 203, and a plant lamp 205; the base 203 is rotatably connected with the fan-shaped bracket 201, and the fan-shaped bracket 201 is equipped with a plant lamp 205 and an infrared camera 202; the plant lamp 205 and the infrared camera 202 are electrically connected to a control chip arranged inside the base 203.

[0036] The sliding support 20 also includes a stepper motor, a pulley 204, and a control chip. Pulleys 204 are installed at the four corners of the bottom end of the base 203, so that the base 203 can slide on the track 10. The base 203 is installed with a stepper motor and a control chip. The control chip is used to receive, convert and transmit signals to control the infrared camera 202, the stepper motor, and the plant light 205.

[0037] like Figure 4-6 As shown, further, the fan-shaped bracket 201 includes two fan-shaped frames 211, and a plurality of latch teeth 212 are equidistantly arranged on the opposite end faces of the two fan-shaped frames 211, and these latch teeth 212 are equidistantly distributed; they are used to latch the infrared camera to realize manual adjustment of the overhead and upward shooting angles; the mechanized design reduces the economic cost, and the track can be arranged at a high place or a low place. Compared with a high place, a low place is easier to adjust the angle, maintain, and clean.

[0038] In one specific embodiment, the fan-shaped frame 211 is welded by a plurality of straight rods 211 - 1 and arc-shaped support rods 211 - 2 , and has a simple structure and low cost.

[0039] In one of the specific embodiments, a linear rod 211 - 1 of a fan-shaped frame 211 is provided with a guide block 211 - 3 for pulling the wires of the infrared camera 202 and the plant light 205 to avoid cluttered lines and leakage.

[0040] Specifically, the track 10 includes two vertical parts 101 parallel to each other, and an inclined part 102 arranged at the bottom of the vertical part; wherein the horizontal line of the inclined part 102 is inclined downward by 1-5 degrees, which does not hinder the movement of the sliding support and also has a good hydrophobic effect; It also includes a U-shaped base frame 103 connecting the bottom ends of the two inclined parts 102. The U-shaped base frame plays a role in drainage. If dew carried by photosynthesis or spraying falls on the track system, it can be discharged through the open ports at both ends of the U-shaped base frame to avoid water accumulation.

[0041] In one specific embodiment, Figure 7As shown, the U-shaped chassis 103 is composed of a plurality of closed plates forming a U-shaped structure, and the first and second ends of the U-shaped structure are open ports. If the vegetation that is easy to shed leaves falls on the track, it can be swept down at one time, reducing the odor caused by the fermentation of fallen leaves and accumulated water, and will not hinder the movement of the sliding support.

[0042] In one specific embodiment, Figure 8 As shown, the U-shaped base frame 103 is composed of a plurality of mesh plates forming a U-shaped structure, and the head and tail ends of the U-shaped structure are open port-like structures, which have strong hydrophobicity and reduce water accumulation. Even if fallen leaves fall on the base frame, in the absence of water or in the absence of water, the possibility of fermentation is low and the movement of the sliding support is not hindered.

[0043] In one specific embodiment, the inclined portion 102 of the track 10 has a plurality of equally spaced drainage grooves 121 opened downwardly on a plane for track drainage, and the distance between two adjacent drainage grooves 121 is more than twice the groove width of the drainage groove 121 to prevent obstruction of the movement of the sliding support.

[0044] In one specific embodiment, the outer surface of the track 10 is coated with a layer of waterproof coating to prevent the metal material from rusting due to long-term immersion in a water mist environment, increasing the sliding resistance and thus increasing the system operation cost.

[0045] In one specific embodiment, the track 10 is preferably made of stainless steel, which is less prone to rust.

[0046] The intelligent fill light system control method based on the plant intelligent fill light device comprises the following steps: S1, collect healthy or unhealthy plant images and input them into the trained plant classification model; S2, using an infrared camera to identify plant images, obtain images of plants currently growing, and then extract the number and size of leaves, leaf veins, and thickness of stems of the plant; S3, after obtaining the plant image, the plant classification model identifies the plant image, obtains plant species information, growth stage information, and disease information, and after obtaining the plant species, continues to input into the identification of the plant growth stage; S4, after obtaining the plant type, growth stage, and disease information, combined with the number and size of the plant's leaves, the thickness of the leaf veins and stems; call the plant spectrum database we established, find the corresponding light ratio data, and output it to the control system through the wireless communication module; S5, the control system outputs PWM waves to control LED lights with different wavelengths.

[0047] It also includes a clock module for presetting a timing so that the control system can control the opening and closing of the plant lamp and the operation of the sliding support; and a Bluetooth module for wirelessly connecting the control system with the plant classification module.

[0048] The S2 step includes the following steps: S21; when the infrared camera is not used, the sliding support is stopped at one end of the track, away from vegetation, to reduce the contact between the water vapor generated by photosynthesis and the infrared camera. Only when necessary, the sliding support is controlled by the control system to slide and shoot; S22; during operation, the plant images taken by the infrared camera use the API of Baidu Cloud Intelligent Cloud to identify the plant species, and then use the Opencv plant classification model to perform feature recognition and color recognition on the plant images; use the Canny edge detection algorithm and the local fuzzy clustering algorithm to identify and extract the leaf veins and stem thickness, and leaf size, so as to facilitate the subsequent comparison with disease information.

[0049] S23; After the operation is completed, the sliding support is stopped at one end of the track, away from vegetation.

[0050] Among them, the Canny edge detection algorithm detects edges through global ratio values ​​and local thresholds, which can detect more detailed edges while avoiding false edges; the local fuzzy clustering algorithm can automatically extract leaf veins, effectively avoid the influence of light, and extract a relatively complete leaf vein area; mathematical methods are used to describe the leaf veins and leaf shapes of plants; by scanning plant leaves and extracting leaf vein images, mathematical methods can be used to describe and analyze them.

[0051] In step S4, S41: Obtain plant image information according to step S3, compare it with images of the plant at the growth stage reached within a certain period of time, and if they do not match, compare it with images of the plant when the plant is diseased, and collect light environment information at the same time, and combine the judgment to determine whether the plant lacks light; if it is in a light environment, the plant light is turned off; if it is in a dark environment, the plant light is turned on; S42: According to the light ratio data, the light of the LEDs with different wavelengths provided on the plant lamp is regulated by PWM waves; the plant lamp is turned on and off at a preset timing.

[0052] The above intelligent fill light system control method can accurately and effectively eliminate the possibility of plant diseases and insect pests or plant dwarfing and other disease problems, and can clearly and effectively fill light for the lack of light source.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
