Description

Technical Field

[0001] The present application relates to the technical field of plant lighting lamps, and in particular to a plant lighting lamp. Background Art

[0002] In plant breeding sheds, plant lighting is needed to provide the required spectrum for plants to simulate sunlight. Plant lighting will emit different spectra to meet the lighting needs of different plants, such as greenhouse flowers: greenhouse flowers refer to ornamental plants that must be cultivated in greenhouses all year round or for a period of time. The environmental conditions of the greenhouse can be partially or completely controlled by humans. For example, jasmine is an open-air flower in southern China, while it is a greenhouse flower in North China and Northeast China. In the process of growing greenhouse flowers, plant lighting is needed to supplement the light to ensure that the photosynthesis of flowers can proceed normally. Therefore, it is particularly important to keep the lampshade clean, especially in large breeding sheds with a large number of breeding boxes and plant lighting. In the absence of maintenance, the lampshade of the plant lighting will be attached to dust. In addition, since plants need to be sprayed with water for irrigation during their growth, the environment is in a humid state for a long time, and mold spots will appear on the lampshade. The mold spots will block the light, causing the spectrum emitted by the lighting to be changed, and the growth of plants with high spectrum requirements and sensitive to the spectrum will be affected.

[0003] For example, an LED plant lamp for greenhouse flower cultivation with publication number: CN212361840U can automatically clean foreign objects on the lampshade plate of the cylindrical LED lamp body by setting a rotatable brush. Although it can clean the plant lighting, it cannot achieve an ideal cleaning effect for stubborn stains such as mildew. Summary of the invention

[0007] The controller is used to obtain the type of stains on the lampshade according to the external image, specifically comprising: identifying the external image through a gray level co-occurrence matrix to extract texture features of the image, and when the texture features are extracted, it is determined to be a mildew stain, otherwise it is determined to be dust;

[0008] The step of identifying the external image by using a gray level co-occurrence matrix to extract the texture features of the image specifically includes:

[0009] Convert the image to grayscale;

[0010] Determine the values ​​of the distance d and the angle θ between the pixel pairs, where the distance refers to the distance between the pixel pairs and the angle refers to the direction between the pixel pairs;

[0033] A plant lighting lamp, the plant lighting lamp comprises a lampshade 11, a lighting lamp arranged inside the lampshade 11, a camera and a cleaning mechanism arranged outside the lampshade 11; the cleaning mechanism comprises a water spray assembly 22 and a wiper mechanism; the camera is used to obtain an external image of the lampshade 11; the water spray assembly 22 and the wiper mechanism mentioned above are both installed on a cleaning seat 21, the plant lighting lamp further comprises a cleaning seat 21, the cleaning seat 21 is movably installed on the lighting lamp; and the water spray assembly 22 and the wiper mechanism are both installed on the cleaning seat 21; the plant lighting lamp further comprises a driving assembly 23, which is used to move the cleaning seat 21 along the side of the lighting lamp so that the cleaning seat 21 can be switched between a working position and a standby position: in the working position, as Figure 1 As shown, the cleaning seat 21 is located in the area below the lampshade 11, in the standby position, as shown in FIG. Figure 2 As shown, the cleaning seat 21 is located in the area below the lampshade 11 of the lighting lamp, the wiper mechanism is used to scrape off the water stains remaining in the water spray assembly 22, and the drive assembly 23 is connected to the controller;

[0034] Through the operation of the driving assembly 23, the cleaning seat 21 can be moved to the corresponding position of the lampshade 11, so as to facilitate cleaning of the stains on the lampshade 11;

[0035] Based on the above structure, Figure 6As shown, the water spray assembly 22 includes a telescopic rod 221 and a water spray head 222, the water spray head 222 is used to spray water to remove stains on the lampshade 11, the fixed end of the telescopic rod 221 is installed on the cleaning seat 21, the water spray head 222 is installed on the telescopic end of the telescopic rod 221, the spray direction of the water spray head 222 is perpendicular to the axial direction of the telescopic rod 221, and there is an angle α between the axial direction of the telescopic rod 221 and the cleaning seat 21; preferably, the water spray head 222 is used to spray ammonia water or clean water. Specifically, the water spray head 222 is connected to two water pumps, which respectively transport ammonia water and clean water to the water spray head 222.

[0036] Based on the above structure, Figure 3 As shown, the driving assembly 23 includes: a guide rail 231, which is installed on the side of the illuminating lamp, and the two sides of the cleaning seat 21 are movably embedded in the guide rail 231; a pulley assembly 232, which is installed on the side of the illuminating lamp, and the belt of the pulley assembly 232 is fixed to the cleaning seat 21. Through the rotation of the pulley assembly 232, the belt will roll, so that the cleaning seat 21 moves forward and backward along the guide rail 231, so as to control the movement of the cleaning seat 21;

[0037] Furthermore, the plant lighting lamp further includes a controller disposed inside the lampshade 11, the pulley assembly 232 is connected to the controller, the controller is used to obtain the location and category of the stains on the lampshade 11 according to the external image, and the controller is further used to control the cleaning mechanism to move to a corresponding position and control the cleaning mechanism to perform automatic cleaning.

[0038] The controller is used to obtain the type of stains on the lampshade 11 according to the external image, specifically comprising: identifying the external image through a gray level co-occurrence matrix to extract texture features of the image, and when the texture features are extracted, it is determined to be a mildew stain, otherwise it is determined to be dust;

[0039] The step of identifying the external image by using a gray level co-occurrence matrix to extract the texture features of the image specifically includes:

[0040] Convert the image to grayscale;

[0041] Determine the values ​​of the distance (d) and angle (θ) between the pixel pairs, where the distance refers to the distance between the pixel pairs and the angle refers to the direction between the pixel pairs;

[0042] For each pixel in the image, find the neighboring pixels at the specified distance and angle, record their grayscale values ​​to construct a grayscale co-occurrence matrix, where the rows and columns of the grayscale co-occurrence matrix represent different grayscale values, and the element P(i, j, d, θ) in the matrix represents the number of times grayscale values ​​i and j appear at the same time at the distance d and angle θ;

[0043] Calculating its texture features according to relevant information in the gray level co-occurrence matrix, wherein the relevant information includes contrast, uniformity and energy;

[0044] Specifically, through the formula Get the contrast in the gray level co-occurrence matrix;

[0045] Determine whether the contrast Contrast exceeds the set value. If yes, it is determined that there is texture, otherwise it is determined that there is no texture. L is the number of gray levels; i and j represent two different gray levels respectively. The above formula calculates the probability of all possible gray level pairs (i, j) multiplied by the sum of the squares of their differences. The higher the contrast, the greater the texture change of the image and the more obvious the gray difference between adjacent pixels. By calculating the contrast, the texture features of the image can be quantified, which helps to identify and classify different texture areas in the image.

[0046] By formula Get the homogeneity in the gray level co-occurrence matrix;

[0047] Determine whether the homogeneity exceeds the set value. If yes, it is determined that there is texture, otherwise it is determined that there is no texture. This formula calculates the probability of all possible gray level pairs (i, j) multiplied by The sum. This term decreases as the difference between i and j increases. Therefore, when i and j are close, the value of this term is larger, reflecting the similarity of grayscale values. The higher the uniformity feature, the more uniform the local texture of the image, that is, the grayscale changes in the image are smaller and the texture is more consistent.

[0048] By formula Get the energy Energy in the gray-level co-occurrence matrix;

[0049] It is determined whether the energy Energy exceeds a set value, if yes, it is determined that a texture exists, otherwise it is determined that a texture does not exist, and L is the number of gray levels.

[0050] This formula calculates the sum of the squares of all element values ​​in the gray-level co-occurrence matrix. The calculation result of the energy feature can reflect the texture consistency of the image and the uniformity of the gray-level distribution. When the image is uniform or the texture is consistent, the energy is large; conversely, when the image texture is uneven, the energy is small.

[0051] The above method can be used to analyze whether the stains remaining on the outside of the lampshade 11 are mildew spots. If it is determined to be mildew spots, the water spray component 22 is controlled to spray 5% ammonia water to clean the stains. Ammonia water is strongly alkaline and can destroy the cell structure of mold. Mold is difficult to survive in an alkaline environment, so ammonia water can inhibit the growth of mold. At the same time, ammonia water can be used as nitrogen fertilizer. Appropriate application of ammonia water can provide nitrogen nutrition for plants and promote plant growth and development.

[0052] If the stain is analyzed as dust through the above method, use clean water to clean it.

[0053] In the above, the method of spraying water on the stains by the water spraying component 22 includes the following steps: Figure 7 As shown:

[0054] S31, the controller analyzes and determines the position of the stain on the lampshade 11 through the external image:

[0055] Set the distance from the water spray head 222 to the stain as Y;

[0056] The distance from the side of the lampshade 11 close to the telescopic rod 221 to the stain is set to X2;

[0057] S32, driving the cleaning seat 21 to move a distance Y by controlling the driving assembly 23;

[0058] S33, control the telescopic rod 221 to extend a distance of Z2, Z2= ;

[0059] Wherein, Z1 is the distance from the water spray head 222 to the intersection when the telescopic rod 221 is retracted to the minimum, and X1 is the distance from the edge of the lampshade 11 close to the telescopic rod 221 to the intersection;

[0060] The intersection is the intersection of the extended line of the axis of the lampshade 11 in the width direction and the extended line of the axis 214 of the telescopic rod 221;

[0061] S34, control the water spray head 222 to spray water, and the spray distance of the water flow is S, In step S34, if the controller analyzes that the stain is a mildew stain, the water spray head sprays ammonia water, otherwise the water spray head sprays clean water;

[0062] Among them, X=X1+X2, Z=Z1+Z2.

[0063] In the above, the method in which the controller obtains the position of the stain on the lampshade 11 according to the external image includes:

[0064] S311, creating a coordinate system on the surface of the lampshade 11, and defining the corner of the lampshade 11 close to the water spray head 222 in the external image as the origin of the coordinate system;

[0065] S312, defining the Y-axis of the coordinate system to point to the length direction of the lampshade 11, and the X-axis of the coordinate system to point to the width direction of the lampshade 11;

[0066] S313, defining and identifying a pixel point of the stain in the external image as a first pixel point, and a pixel point of the origin of the coordinate system in the external image as a second pixel point;

[0067] S314, identifying the distance between the first pixel point and the second pixel point in the X-axis direction and in the Y-axis direction, and forming the coordinates of the first pixel point, and determining the value of the first pixel point in the Y-axis as Y', and the value of the first pixel point in the X-axis as X';

[0068] S315. Determine Y'=Y, X'=X2.

[0069] By means of the above method, water can be precisely sprayed to the location of the stain. After the spraying is completed, the wiper mechanism scrapes off the water stain remaining in the spray mechanism. The method for the wiper mechanism to scrape off the water stain includes:

[0070] The motor 212 is controlled to rotate the shaft 214 so that the top of the scraper 211 is against the bottom of the lampshade 11, and then the cleaning seat 21 is driven to move by the driving component 23. After the top of the scraper 211 scrapes the stain position, the motor 212 is controlled to rotate the shaft 214 so that the top of the scraper 211 is placed in the through groove 213; the cleaning seat 21 is driven to move by the driving component 23, and the cleaning seat 21 enters the standby position, such as Figure 4 and Figure 5 As shown;

[0071] It should be noted that the telescopic rod 221 is installed on a predetermined side of the cleaning seat 21, and the predetermined side is a side of the cleaning seat 21 away from the moving direction of switching from the standby position to the working position. Figure 8 As shown, the telescopic rod 221 is located on the side of the cleaning seat 21 away from the lampshade 11. If there is a stain on the lampshade 11 at this time, when the driving component 23 moves the water spray component 22 to the position of the stain, the position of the telescopic rod 221 will be aligned with the position of the stain, which will make the cleaning seat 21 closer to the front than the telescopic rod 221. Figures 8 to 9As shown, after the water spray head 222 sprays the stains, the driving assembly 23 moves the cleaning seat 21 back and the scraper 211 can scrape off the water stains remaining on the lampshade 11.
