Description

Technical Field

[0001] This application relates to the technical field of energy-saving lighting device control. More specifically, this application relates to an energy-saving light-emitting diode plant lighting lamp and its dimming control method. Background Art

[0002] The control of energy-saving lighting devices is the core of modern lighting systems, covering from basic switch operations to complex intelligent regulation and automation control. Traditional lighting systems mainly rely on physical switches and dimmers to control the light distribution by simple current regulation. However, with the development of technology, in energy-saving lighting devices, lighting control has become more complex and intelligent. Existing plant lighting control includes various advanced means, such as sensor-based automatic adjustment, wireless network control, and integrated control systems. In addition, the control of energy-saving lighting devices also adjusts the light distribution with regulating elements. Among them, sensor technology enables the lights to automatically adjust according to the ambient brightness and time period, improving the energy utilization efficiency and avoiding resource waste. Additionally, wireless control systems, such as Wi-Fi, Bluetooth, and Zigbee, enable remote operation and customized settings, allowing users to adjust the light state through a smartphone or voice assistant.

[0003] In the prior art, the control of energy-saving plant lighting lamps mainly automatically adjusts the spectral combination, light intensity, and time according to the growth requirements of plants through an intelligent module to meet the needs of different growth stages. In addition, environmental sensors such as light intensity, temperature, and humidity sensors can monitor the plant growth environment in real time and automatically adjust the light settings to optimize the growth conditions. Additionally, the plant lighting lamps can also integrate a timing control function to provide remote control and monitoring simulation, enabling users to flexibly adjust the lighting scheme to ensure that plants obtain the best lighting conditions. However, in the dimming control of energy-saving light-emitting diode plant lighting lamps, for different requirements of irradiation coverage intensity, the plant lighting lamps need to be adjusted at different angles. When the plant lighting lamps are deflected and adjusted, there will be a problem of light intensity centralization (that is, the problem that the light intensity gradually decreases from the irradiation center to both sides), resulting in irradiation shadows and uneven irradiation overlap in some irradiation areas of the target plant (that is, the irradiation areas of the light source overlap too much in some places and not enough in other places, resulting in uneven light intensity distribution in the entire irradiation area), and further leading to a decrease in the effective light distribution of the target plant. Therefore, how to achieve uniform irradiation of the target plant under the influence of light intensity centralization, so as to improve the effective light distribution of the plant lighting lamp on the target plant has become a difficult problem faced by the industry.

In summary, the technical solution provided by the present application can realize uniform illumination of the target plant under the influence of light intensity centralization, thereby improving the effective light distribution of the plant lighting lamp on the target plant.

[0052] The core of this application is to first start an energy-saving light-emitting diode plant lighting lamp and obtain the irradiation data when the plant lighting lamp irradiates a target plant; secondly, determine the irradiation characteristic parameters of the plant lighting lamp according to various irradiation attributes of the plant lighting lamp, cascade the characteristics of the irradiation data through the irradiation characteristic parameters to obtain an irradiation cascade characteristic sequence, and divide the irradiation cascade characteristic sequence to obtain the weak light area when the plant lighting lamp irradiates the target plant; further, obtain the light intensity distribution data when the plant lighting lamp irradiates, extract multiple irradiation outer edge components when the plant lighting lamp irradiates from the light intensity distribution data, and determine the irradiation response interval of the plant lighting lamp through all the irradiation outer edge components and the weak light area; then, determine the confidence deflection coefficient when the plant lighting lamp irradiates the target plant based on the spatial characteristics of the irradiation response interval and the weak light area; finally, control the plant lighting lamp to deflect and irradiate towards the weak light area according to the confidence deflection coefficient, which can achieve uniform irradiation of the target plant under the influence of light intensity centralization, thereby improving the effective light distribution of the plant lighting lamp to the target plant.

[0053] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. Refer to Figure 1 , this figure is an exemplary flowchart of a dimming control method for an energy-saving light-emitting diode plant lighting lamp according to some embodiments of the present application. The dimming control method 100 for the energy-saving light-emitting diode plant lighting lamp mainly includes the following steps:

[0054] In step 101, start the energy-saving light-emitting diode plant lighting lamp and obtain the irradiation data when the plant lighting lamp irradiates the target plant.

[0055] It should be noted that the energy-saving light-emitting diode plant lighting lamp in this application refers to a lighting device used for plant growth. While providing the required spectrum, the energy-saving light-emitting diode plant lighting lamp also has low energy consumption. Through efficient light sources and intelligent control technologies, the energy-saving light-emitting diode plant lighting lamp aims to provide the best lighting conditions for plants while reducing energy consumption and operating costs.

[0056] Specifically, when starting the energy-saving light-emitting diode plant lighting lamp, obtain the irradiation data when the plant lighting lamp irradiates the target plant through the plant lighting monitoring database. The irradiation data includes irradiation images collected in the same irradiation area at multiple different time points. The irradiation images can be collected by a camera. The irradiation images represent the images collected in the target plant irradiation area under the irradiation of the energy-saving light-emitting diode plant lighting lamp. The irradiation images show how light propagates in the irradiation area. By collecting the irradiation images, the light-receiving effect of the target plant can be effectively analyzed.

[0057] It should be noted that in this embodiment, the plant lighting monitoring database refers to a data system for collecting, storing, managing, and analyzing data related to plant lighting. This database is typically used to monitor and optimize the lighting conditions in the plant growth environment to ensure that plants grow under the most suitable lighting. The data in the database includes information such as irradiation image data, light intensity distribution data, irradiation time, light uniformity, and feedback on plant growth.

[0058] In step 102, based on multiple types of irradiation attributes of the plant lighting lamp, the irradiation characteristic parameters of the plant lighting lamp are determined. Through the irradiation characteristic parameters, the irradiation data is subjected to feature concatenation to obtain an irradiation concatenated feature sequence. From the irradiation concatenated feature sequence, the weak irradiation area of the plant lighting lamp when irradiating the target plant is divided.

[0059] In some embodiments, refer to Figure 2 As shown, this figure is an exemplary flowchart for determining irradiation characteristic parameters according to some embodiments of the present application. In this embodiment, the irradiation characteristic parameters of the plant lighting lamp can be determined based on multiple types of irradiation attributes of the plant lighting lamp by the following steps:

[0060] First, in step 1021, multiple types of irradiation attributes of the plant lighting lamp are obtained.

[0061] Secondly, in step 1022, irradiation sensitivity analysis is performed on each type of irradiation attribute to obtain the irradiation sensitivities of each type of irradiation attribute.

[0062] Finally, in step 1023, the irradiation characteristic parameters of the plant lighting lamp are determined based on all the irradiation sensitivities.

[0063] Specifically, multiple types of irradiation attributes of the plant lighting lamp can be obtained through the plant lighting monitoring database. The multiple types of irradiation attributes include spectral distribution characteristics, light intensity characteristics, and lighting angle characteristics. Among them, in the present application, the irradiation attributes represent the key performance characteristics of the plant lighting lamp when providing lighting for the target plant. These characteristics directly affect the growth of plants and the energy utilization efficiency. By obtaining the irradiation attributes, the effectiveness of the target plant irradiated by the plant lighting lamp can be effectively analyzed.

[0064] In specific implementation, the irradiation sensitivity analysis can be performed on each type of irradiation attribute by using the Sobol index method in the existing sensitivity analysis methods to obtain the irradiation sensitivities of each type of irradiation attribute, which will not be elaborated here. In addition, in other embodiments, other sensitivity analysis methods can also be used to perform the irradiation sensitivity analysis on each type of irradiation attribute. For example, the variance decomposition method and the gradient method are not limited here. In addition, it should be noted that in this embodiment, the irradiation sensitivity represents the response degree of the irradiation attribute when the plant lighting lamp irradiates the target plant, that is, the greater the irradiation sensitivity, the greater the response degree of the irradiation attribute when the plant lighting lamp irradiates the target plant, and vice versa.

[0065] In specific implementation, the irradiation characteristic parameter of the plant lighting lamp is determined according to all the irradiation sensitivities, that is: the mean value of all the irradiation sensitivities is calculated, and the result of the mean value calculation is used as the irradiation characteristic parameter of the plant lighting lamp. In addition, in other embodiments, other calculation methods can also be used to calculate the irradiation characteristic parameter of the plant lighting lamp, which is not limited here.

[0066] It should be noted that in this application, the irradiation characteristic parameter represents the degree of sensitivity of the description of the light on the target plant area, that is, the greater the irradiation characteristic parameter, the greater the degree of sensitivity of the light on the target plant area, and vice versa. In the control of the plant lighting lamp, it is usually necessary to analyze the light intensity to ensure that the target plant receives sufficient light, thereby effectively improving the cultivation efficiency of the target plant. Therefore, by determining the irradiation characteristic parameter, the sensitive degree of the current target plant to light can be effectively analyzed.

[0067] In some embodiments, the irradiation data is subjected to feature concatenation through the irradiation characteristic parameter to obtain the irradiation concatenated feature sequence, which can be specifically performed by the following steps, that is:

[0068] Feature enhancement is performed on each irradiation image in the irradiation data according to the irradiation characteristic parameter to obtain all the irradiation feature enhancement maps;

[0069] Cascade fusion analysis is performed on all the irradiation feature enhancement maps to obtain multiple irradiation concatenated feature values;

[0070] All the irradiation concatenated feature values are combined to obtain the irradiation concatenated feature sequence.

[0071] In specific implementation, each illumination image in the illumination data is enhanced in features according to the illumination feature parameters to obtain all illumination feature enhancement maps, that is: for each illumination image, the illumination feature parameters are respectively summed with the pixel values of each pixel point in the illumination image to obtain the pixel enhancement values of each pixel point, and all the pixel enhancement values are correspondingly replaced with the original pixel values in the illumination image, thereby obtaining all the illumination feature enhancement maps. In addition, in other embodiments, other calculation methods can also be used to calculate the pixel enhancement values, which are not limited herein.

[0072] It should be noted that in this embodiment, the illumination feature enhancement map represents the illumination image after feature enhancement. In addition, the scale sizes of each illumination feature enhancement map are the same.

[0073] Among them, in some embodiments, cascade fusion analysis is performed on all the illumination feature enhancement maps to obtain multiple illumination cascade feature values. Specifically, the following steps can be adopted, that is:

[0074] Align the scales of all the illumination feature enhancement maps;

[0075] Perform pixel-level cascade fusion on all the aligned illumination feature enhancement maps to obtain multiple illumination cascade feature values.

[0076] In specific implementation, the scales of all the illumination feature enhancement maps can be aligned through the Gaussian pyramid in image processing. In addition, in other embodiments, other alignment methods can also be used to align the scales of all the illumination feature enhancement maps, which are not limited herein.

[0077] In specific implementation, pixel-level cascade fusion can be performed on all the aligned illumination feature enhancement maps through the Laplacian pyramid in image processing to obtain multiple illumination cascade feature values. In addition, in other embodiments, other cascade fusion methods can also be used to perform pixel-level cascade fusion on all the aligned illumination feature enhancement maps, which are not limited herein.

[0078] It should be noted that in this embodiment, when performing pixel-level cascade fusion on the aligned illumination feature enhancement maps, the pixel values of each pixel point are used as the fusion objects. Therefore, one pixel value corresponds to one illumination cascade feature value.

[0079] It should be noted that in this application, the illumination cascade feature sequence represents a sequence containing multiple illumination cascade feature values. The illumination cascade feature value represents the feature value obtained after cascade fusion of multiple illumination feature enhancement maps. The illumination cascade feature value reflects the illumination distribution amount of the target plant. By determining the illumination cascade feature value, it is to identify the contours of the dark and bright areas when the target plant is illuminated, so as to characterize the light-deficient areas of the target plant when illuminated by the plant lighting lamp.

[0080] In addition, it should be noted that in this application, the feature cascade represents the process of fusing multiple features. Among them, the irradiation data is subjected to feature cascade through the irradiation feature parameters, that is: each irradiation image in the irradiation data is subjected to feature enhancement according to the irradiation feature parameters to obtain all irradiation feature enhancement maps; cascade fusion analysis is performed on all irradiation feature enhancement maps, and then multiple irradiation cascade feature values are obtained; all irradiation cascade feature values are combined to obtain an irradiation cascade feature sequence, that is, the feature cascade of the irradiation data is realized.

[0081] In some embodiments, the following steps may be specifically adopted to divide the weak light irradiation area of the plant lighting lamp when irradiating the target plant from the irradiation cascade feature sequence, that is:

[0082] Collect the monitoring image when the current plant lighting lamp irradiates the target plant;

[0083] Extract the maximum irradiation cascade feature value and the minimum irradiation cascade feature value in the irradiation cascade feature sequence;

[0084] Determine the low illuminance recognition coefficient of the plant lighting lamp according to the maximum irradiation cascade feature value and the minimum irradiation cascade feature value;

[0085] Perform low illuminance recognition on the monitoring image by the low illuminance recognition coefficient to obtain multiple low illuminance recognition points;

[0086] Connect the regions of each low illuminance recognition point to obtain the weak light irradiation area of the plant lighting lamp when irradiating the target plant.

[0087] When specifically implemented, the monitoring image when the current plant lighting lamp irradiates the target plant can be collected by a camera, which will not be elaborated here.

[0088] When specifically implemented, determine the low illuminance recognition coefficient of the plant lighting lamp according to the maximum irradiation cascade feature value and the minimum irradiation cascade feature value, that is: calculate the mean value of the maximum irradiation cascade feature value and the minimum irradiation cascade feature value, and use the result of the mean value calculation as the low illuminance recognition coefficient of the plant lighting lamp. In addition, in other embodiments, other calculation methods can also be used to calculate the low illuminance recognition coefficient, which will not be elaborated here.

[0089] It should be noted that the low illuminance recognition coefficient in this embodiment represents the value used to identify the area where the target plant is insufficiently illuminated, that is, when it exceeds the low illuminance recognition coefficient, it means that the area is insufficiently illuminated.

[0090] In specific implementation, the low-light recognition coefficient is used to perform low-light recognition on the monitoring image, and a plurality of low-light recognition points are obtained, that is: the low-light recognition coefficient is compared with the pixel value corresponding to each pixel point in the monitoring image, and all pixel values greater than or equal to the low-light recognition coefficient are extracted, and the pixel points corresponding to the extracted pixel values are used as low-light recognition points. For all pixel values less than the low-light recognition coefficient, no processing is performed. It should be noted that in this embodiment, the low-light recognition points are points used to characterize the insufficient light reception of the target plant.

[0091] In specific implementation, the regional growth algorithm in image processing can be used to connect the regions of each low-light recognition point to obtain the weak-light irradiation area of the plant illumination lamp when irradiating the target plant. In addition, in other embodiments, other regional connection methods can also be used to connect the regions of each low-light recognition point, which is not limited here.

[0092] It should be noted that in this application, the weak-light irradiation area refers to the area where the plant illumination lamp has insufficient illumination on the target plant. The light intensity in the weak-light irradiation area is significantly lower than that in the surrounding areas, indicating that there is a problem of uneven illumination. In the application of plant illumination, the existence of the weak-light irradiation area will cause insufficient light in some areas, thus affecting plant growth or illumination effect. Therefore, by determining the weak-light irradiation area, the area where the target plant has insufficient light reception under the irradiation of the plant illumination lamp can be effectively identified, enabling better angle adjustment of the plant illumination lamp to adapt to the required light distribution, and thus avoiding the influence of uneven irradiation intensity caused by the centralization of light intensity.

[0093] In step 103, the light intensity distribution data when the plant illumination lamp irradiates is obtained, and a plurality of irradiation outer edge components when the plant illumination lamp irradiates are extracted from the light intensity distribution data. The irradiation response interval of the plant illumination lamp is determined by all the irradiation outer edge components and the weak-light irradiation area.

[0094] In specific implementation, the light intensity distribution data when the plant illumination lamp irradiates can be obtained through the plant illumination monitoring database. The light intensity distribution data represents the relevant data of the light intensity distribution when the plant illumination lamp irradiates. For example, the light intensity coverage data. The light intensity distribution data contains the light intensity distribution values collected at different radiation angles, that is, each radiation angle corresponds to a light intensity distribution value. The light intensity distribution value is collected by a light sensor. In this embodiment, the light intensity distribution value represents the light intensity coverage amount of the illumination light of the plant illumination lamp in space, that is, the light intensity distribution value characterizes the light intensity coverage amount. The light intensity distribution value quantifies the geometric characteristics and illumination effect of the illumination area, ensuring the uniformity of light coverage in the irradiation of the target plant, thus ensuring the uniform growth of plants under light and optimizing the illumination energy efficiency of the plant illumination lamp.

[0095] In some embodiments, the following steps may be specifically adopted to extract multiple irradiation outer edge components during the irradiation of the plant lighting lamp from the light intensity distribution data, that is:

[0096] Determine the half-peak light intensity distribution value in the light intensity distribution data;

[0097] Perform an irradiation outer edge analysis on the plant lighting lamp by combining the half-peak light intensity distribution value and the light intensity distribution data to obtain multiple irradiation outer edge components during the irradiation of the plant lighting lamp.

[0098] Specifically, when implementing, determine the half-peak light intensity distribution value in the light intensity distribution data, that is: obtain the peak value of the light intensity distribution in the light intensity distribution data, and dichotomize the peak value of the light intensity distribution to obtain the half-peak light intensity distribution value in the light intensity distribution data.

[0099] It should be noted that in this embodiment, dichotomizing the peak value of the light intensity distribution refers to the process of halving the peak value of the light intensity distribution. In addition, in this embodiment, the half-peak light intensity distribution value represents the value obtained after dichotomizing the peak value of the light intensity distribution.

[0100] Among them, in some embodiments, the following steps may be specifically adopted to perform an irradiation outer edge analysis on the plant lighting lamp by combining the half-peak light intensity distribution value and the light intensity distribution data to obtain multiple irradiation outer edge components during the irradiation of the plant lighting lamp, that is:

[0101] Calculate the absolute difference between the half-peak light intensity distribution value and each light intensity distribution value in the light intensity distribution data to obtain the absolute difference corresponding to each light intensity distribution value;

[0102] Arrange the absolute differences corresponding to each light intensity distribution value in ascending order, and use the light intensity distribution value corresponding to the first absolute difference after ascending order as the first irradiation outer edge component, and use the light intensity distribution value corresponding to the second absolute difference after ascending order as the second irradiation outer edge component.

[0103] It should be noted that in this embodiment, the analysis of the irradiation outer edge represents the process of identifying the outermost irradiation amount during the irradiation of the plant lighting lamp. The irradiation outer edge of the plant lighting lamp is analyzed by combining the half-peak light intensity distribution value with the light intensity distribution data, that is: the absolute difference is calculated between the half-peak light intensity distribution value and each light intensity distribution value in the light intensity distribution data to obtain the absolute difference corresponding to each light intensity distribution value; the absolute differences corresponding to each light intensity distribution value are arranged in ascending order, and the light intensity distribution value corresponding to the first absolute difference after the ascending order is used as the first irradiation outer edge component, and the light intensity distribution value corresponding to the second absolute difference after the ascending order is used as the second irradiation outer edge component, thus completing the analysis of the irradiation outer edge of the plant lighting lamp.

[0104] It should be noted that in this embodiment, the first irradiation outer edge component represents the light intensity distribution value most similar to the half-peak light intensity distribution value, and the second irradiation outer edge component in this embodiment represents the light intensity distribution value second most similar to the half-peak light intensity distribution value. During the irradiation of the plant lighting lamp, the irradiation edge is usually the position corresponding to half of the maximum light intensity distribution value. Therefore, by determining the first irradiation outer edge component and the second irradiation outer edge component, it is to identify the effective edge during the irradiation of the plant lighting lamp.

[0105] It should also be noted that in this application, when the plant lighting lamp irradiates, there will be a phenomenon that the light intensity distribution value in the middle is the largest and the light intensity distribution values at both edges are the smallest, and the light intensity distribution values at both edges will be close to half of the light intensity distribution peak value. Therefore, for the radiation angles corresponding to the light intensity distribution values at the two edges, there will be a radiation angle corresponding to the light intensity distribution value at one edge being greater than the radiation angle corresponding to the light intensity distribution value at the other edge.

[0106] In some embodiments, refer to Figure 3 As shown, this figure is an exemplary flowchart for determining the irradiation response interval according to some embodiments of the present application. In this embodiment, the irradiation response interval of the plant lighting lamp can be determined by all the irradiation outer edge components and the irradiation weak light area through the following steps:

[0107] First, in step 1031, the irradiation characteristic angle of the plant lighting lamp is determined by all the irradiation outer edge components;

[0108] Secondly, in step 1032, the irradiation weak light area is scanned regionally with the position coordinates of the plant lighting lamp as the scanning center point, and then the scanning angles of each boundary point in the irradiation weak light area are obtained;

[0109] Further, in step 1033, perform angular difference analysis on the scanning angles of all boundary points to obtain the maximum scanning angle difference and the minimum scanning angle difference corresponding to the weak illumination area;

[0110] Still further, in step 1034, calculate the absolute difference between the maximum scanning angle difference and the illumination characteristic angle to obtain the lower limit value of the illumination response of the plant lighting lamp;

[0111] Then, in step 1035, perform summation calculation on the minimum scanning angle difference and the illumination characteristic angle to obtain the upper limit value of the illumination response of the plant lighting lamp;

[0112] Finally, in step 1036, construct the illumination response interval of the plant lighting lamp through the lower limit value of the illumination response and the upper limit value of the illumination response.

[0113] Among them, in some embodiments, the following steps can be specifically adopted to determine the illumination characteristic angle of the plant lighting lamp through all illumination outer edge components, that is:

[0114] Obtain all illumination outer edge components, and all illumination outer edge components include the first illumination outer edge component and the second illumination outer edge component;

[0115] Determine the radiation angle loss margin when the plant lighting lamp irradiates;

[0116] Determine the illumination characteristic angle of the plant lighting lamp according to the radiation angle corresponding to the first illumination outer edge component, the radiation angle corresponding to the second illumination outer edge component, and the radiation angle loss margin.

[0117] When specifically implemented, determine the radiation angle loss margin when the plant lighting lamp irradiates, and the radiation angle loss margin can be obtained by querying the parameter nameplate of the plant lighting lamp, that is, the radiation angle loss margin is preset. In this embodiment, the radiation angle loss margin represents the radiation angle that can allow fluctuations set due to the self-illumination accuracy when the plant lighting lamp irradiates.

[0118] When specifically implemented, determine the illumination characteristic angle of the plant lighting lamp according to the radiation angle corresponding to the first illumination outer edge component, the radiation angle corresponding to the second illumination outer edge component, and the radiation angle loss margin, that is: calculate the absolute difference between the radiation angle corresponding to the first illumination outer edge component and the radiation angle corresponding to the second illumination outer edge component, and use the sum of the absolute difference calculation result and the radiation angle loss margin as the illumination characteristic angle of the plant lighting lamp. In addition, in other embodiments, other calculation methods can also be used to calculate the illumination characteristic angle of the plant lighting lamp, which is not limited here.

[0119] It should be noted that in this application, the irradiation characteristic angle represents the coverage range of the light rays in space when the plant lighting lamp irradiates, which is expressed in terms of an angle. The irradiation characteristic angle defines the range in which the light beam spreads from the center of the light source to the edge. The irradiation characteristic angle determines the size and shape of the illumination area. Therefore, by determining the irradiation characteristic angle, the light uniformity and light coverage when the plant lighting lamp irradiates the target plant can be effectively analyzed.

[0120] In specific implementation, a scanner can be used to perform area scanning on the weak irradiation area with the position coordinates of the plant lighting lamp as the scanning center point, and then the scanning angles of each boundary point in the weak irradiation area can be obtained. Among them, each boundary point in the weak irradiation area can be detected by a Sobel operator, which will not be elaborated here. It should be noted that in this embodiment, the scanning angle of the boundary point represents the angle obtained by scanning at the boundary point in the weak irradiation area.

[0121] Among them, in some embodiments, to perform angle difference analysis on the scanning angles of all boundary points to obtain the maximum scanning angle difference and the minimum scanning angle difference corresponding to the weak irradiation area, the following steps can be specifically adopted, that is:

[0122] Select the scanning angle of a boundary point as the selected scanning angle;

[0123] Perform absolute difference calculation on the selected scanning angle and the scanning angles of the remaining boundary points to obtain all the scanning angle differences, and extract the maximum scanning angle difference and the minimum scanning angle difference corresponding to the weak irradiation area from all the scanning angle differences.

[0124] It should be noted that in this embodiment, the angle difference analysis represents the process of calculating the absolute difference between scanning angles. Among them, in this embodiment, the scanning angle difference represents the difference between two scanning angles.

[0125] It should be noted that in other embodiments, the irradiation response lower limit value and the irradiation response upper limit value can also be calculated according to other calculation methods, which are not limited here. Among them, in this embodiment, the irradiation response lower limit value represents the minimum response amount when the plant lighting lamp performs irradiation operations, and the irradiation response upper limit value represents the maximum response amount when the plant lighting lamp performs irradiation operations. When the plant lighting lamp irradiates the target plant, the angle of the plant lighting lamp is usually rotated to adjust the light distribution. However, for different irradiation intensities, the irradiation coverage areas are different. It can be rotating the angle of the plant lighting lamp to adjust the large-area light distribution, or rotating the angle of the plant lighting lamp to adjust the small-area light distribution. Therefore, by determining the irradiation response lower limit value and the irradiation response upper limit value, the angle of the plant lighting lamp can be dynamically rotated to effectively adjust the light distribution of the plant lighting lamp, improving the plant growth effect and lighting efficiency.

[0126] It should also be noted that in this application, the irradiation response range represents the response adjustment range of the plant lighting lamp during the irradiation operation. The irradiation response range is composed of the irradiation response lower limit value and the irradiation response upper limit value. By determining the irradiation response range, the angle of the plant lighting lamp can be dynamically rotated, avoiding the irradiation shadows and uneven irradiation overlaps presented in some irradiation areas, and improving the adjustment of subsequent light distribution.

[0127] In step 104, based on the irradiation response range and the spatial characteristics of the irradiation weak light area, the confidence deflection coefficient when the plant lighting lamp irradiates the target plant is determined.

[0128] In some embodiments, the specific steps for determining the confidence deflection coefficient when the plant lighting lamp irradiates the target plant based on the irradiation response range and the spatial characteristics of the irradiation weak light area are as follows:

[0129] Obtain the position information of the irradiation weak light area;

[0130] Extract the spatial characteristics of the irradiation weak light area from the position information;

[0131] Determine the position angle difference according to the spatial characteristics and the current position coordinates of the plant lighting lamp;

[0132] Determine the confidence deflection coefficient when the plant lighting lamp irradiates the target plant through the irradiation response lower limit value of the irradiation response range and the position angle difference.

[0133] When specifically implemented, the position information of the irradiation weak light area can be obtained through the plant lighting monitoring database, and the position information includes the position coordinates of each part of the irradiation weak light area.

[0134] When specifically implemented, the spatial characteristics of the irradiation weak light area are extracted from the position information, that is: the central position coordinates of the irradiation weak light area are obtained from the position information, and the central position coordinates are used as the spatial characteristics of the irradiation weak light area. In this embodiment, the spatial characteristics represent the central coordinate characteristics for measuring the irradiation weak light area in space.

[0135] When specifically implemented, the position angle difference is determined according to the central position coordinates and the current position coordinates of the plant lighting lamp, that is: in the same coordinate space, the spatial characteristics and the current position coordinates of the plant lighting lamp are subjected to angle conversion, and the absolute difference of the converted angles is calculated to obtain the position angle difference. In addition, in other embodiments, other calculation methods can also be used to calculate the position angle difference, which is not limited here.

[0136] It should be noted that the space features and the current position coordinates of the plant lighting lamp can be converted by the arctangent function, which will not be elaborated here. In this embodiment, the position angle difference represents the included angle formed by two position points in the same two-dimensional space.

[0137] When specifically implemented, the confidence deflection coefficient of the plant lighting lamp when irradiating the target plant is determined by the lower limit value of the irradiation response in the irradiation response interval and the position angle difference, that is: the difference between the position angle difference and the lower limit value of the irradiation response is calculated to obtain the confidence deflection coefficient of the plant lighting lamp when irradiating the target plant. In addition, in other embodiments, other calculation methods can also be used to calculate the confidence deflection coefficient when the plant lighting lamp irradiates, which is not limited here.

[0138] It should be noted that in this application, the confidence deflection coefficient represents the deflection amount required for the current plant lighting lamp when irradiating the target plant, that is, it represents the angle amount that the current plant lighting lamp needs to adjust. When the confidence deflection coefficient is larger, the angle amount that the current plant lighting lamp needs to adjust is larger; when the confidence deflection coefficient is smaller, the angle amount that the current plant lighting lamp needs to adjust is smaller. When the plant lighting lamp irradiates the target plant, there is usually a certain adjustment deviation in the deflection adjustment of the plant lighting lamp, resulting in insufficient irradiation accuracy in the target irradiation range. In order to make the illumination-deficient area receive accurate light, the deflection amount of the plant lighting lamp can be adjusted to make the irradiation light cover the target area more accurately. Therefore, the confidence deflection coefficient of the plant lighting lamp when irradiating the target plant can be determined by the lower limit value of the irradiation response in the irradiation response interval and the position angle difference, and the illumination-deficient area can be accurately covered with light according to the confidence deflection coefficient, so as to ensure that the target plant receives sufficient light.

[0139] In step 105, the plant lighting lamp is controlled to deflect and irradiate the illumination-deficient area according to the confidence deflection coefficient.

[0140] In some embodiments, controlling the plant lighting lamp to deflect and irradiate the illumination-deficient area according to the confidence deflection coefficient can be specifically implemented by the following steps, that is:

[0141] The confidence deflection coefficient is uploaded to the plant lighting lamp adjustment system, and the plant lighting lamp adjustment system analyzes the confidence deflection coefficient and controls the plant lighting lamp to deflect and irradiate the illumination-deficient area according to the analysis result, so as to obtain the effective light distribution of the target plant in the illumination-deficient area.

[0142] In specific implementation, the confidence deflection coefficient is analyzed according to the plant lighting lamp adjustment system, that is: the analysis tool provided by the plant lighting lamp adjustment system analyzes the confidence deflection coefficient until the given magnitude of the confidence deflection coefficient is obtained. For example, the analysis tools Apache NiFi and Talend. It should be noted that in this embodiment, analysis is the process of information extraction, which will not be elaborated here.

[0143] It should be noted that in this embodiment, the plant lighting lamp adjustment system represents a mechanical and electronic system for controlling the angle of the plant lighting lamp, which is often used to optimize the direction and distribution of light.
