Description

TECHNICAL FIELD

[0001] The application belongs to the field of LED, and particularly relates to an LED bulb cloud data processing system. BACKGROUND

[0002] With the continuous progress of LED technology, LED bulbs gradually replace traditional lighting devices and occupy a dominant position in the modern lighting field due to the advantages of high efficiency, long service life, environmental protection and the like. In particular, LED bulbs with a multi-lamp bead structure are worth paying attention to, which have unique performance and can independently regulate the brightness and color temperature of each lamp bead to achieve more diverse, flexible and personalized lighting effects. However, at the same time, the multi-lamp bead structure LED bulb also faces the challenge of a substantial increase in the complexity of lighting data management. In order to achieve efficient lighting management of the multi-lamp bead structure LED bulb, LED bulb cloud data processing emerges as the times require.

[0003] There are also some related solutions to the lighting management of the multi-lamp bead structure LED bulb in the prior art. For example, a multi-level color adjusting LED lamp bead control and adjustment management system disclosed in Chinese Patent Publication No. CN114025449B adjusts the system program of the building brightening structure based on the brightening holiday scene after the building brightening structure is arranged on the brightening floor of the building, and then adjusts the actual brightening parameters of the LED lamp bead from the internal and external influencing factors, detects the environment around the brightening building from the other side, and identifies the shielding object, so as to flexibly adjust the LED lamp bead brightening parameters based on the above influencing factors, and improve the adjustment and management mode of the LED lamp bead in the building brightening process.

[0004] Another Chinese Patent Publication No. CN117354986A discloses a kind of intelligent control method and system of multifunctional LED lamp bead, which first identifies the target user behavior mode, combines it with the LED lamp bead operating parameter to obtain the behavior-light operating parameter of the target user, identifies the environmental factors affecting the user's light regulation, and accordingly obtains the environment-light operating parameter of the user, constructs the target user light operating prediction model, predicts the future operating parameter of the LED lamp bead, and accordingly forms an automatic adjustment scheme, finally formulates the LED lamp bead control scheme, effectively adjusts the LED light according to the user behavior and environmental factors, realizes personalized and intelligent lighting, improves user experience and energy saving effect.

[0005] Although the above-mentioned scheme proposes some related solutions to the lighting management of the multi-lamp bead structure LED bulb, the prior art still has the following limitations. Specifically, 1) the prior art lacks real-time lamp bead light efficiency evaluation capability, and cannot quickly and accurately determine and analyze the actual lighting effect of each lamp bead during the lighting process, making it difficult to grasp the real-time working state of the lamp bead.

[0006] 2. The existing technology lacks an instant adaptive control mechanism for lamp beads and relies too much on advance prediction adjustment schemes, resulting in a serious lag in feedback response capabilities and a significant reduction in accuracy. It is unable to fully utilize the advantages of efficient, flexible and precise lighting that multi-lamp bead structure LED bulbs should have, thereby greatly limiting the application scenarios.

[0007] 3. Existing technologies for fault assessment of LED bulbs with multiple lamp beads rely on lighting effect feedback, such as potential manifestations such as lighting brightness not meeting standards, while ignoring in-depth consideration of operating current, operating temperature, and spectral performance. This makes it difficult to accurately detect and locate potential faults, thus severely restricting the reliability, stability, and efficiency of LED bulb lighting systems with multiple lamp beads.

[0028] The lighting effect inspection module is used to inspect the execution effect of the control instructions of the target LED bulb for the lighting area it covers, and identify the lamp beads that do not meet the standards.

[0029] Specifically, the inspection of the execution effect of the control instructions of the target LED bulb for the lighting area it covers includes: collecting the image of the lighting area it covers according to the built-in integrated camera device of the target LED bulb, locating the lighting position coordinates of each working lamp bead in the image corresponding to the lighting position coordinates specified by the control instruction set, combining the preset effective lighting partition form of the built-in lamp beads of the target LED bulb, and identifying the effective lighting partition of each working lamp bead in the image with its lighting position coordinate as the center.

[0030] Determine the actual lighting base point coordinates of the effective lighting partition of each working lamp bead in the image, compare them with the corresponding lighting position coordinates specified by the control instruction set, and analyze the lighting position deviation of each working lamp bead of the target LED bulb.

[0031] It should be noted that the specific analysis process of the lighting position deviation of each working lamp bead of the above-mentioned target LED bulb is: substituting the actual lighting base point coordinates of the effective lighting partition of each working lamp bead in the image and the corresponding lighting position coordinates specified by the control instruction set into the Euclidean distance formula, obtaining the deviation distance between the actual lighting base point coordinates of the effective lighting partition of each working lamp bead in the image and the corresponding lighting position coordinates specified by the control instruction set, and performing a ratio analysis with the preset reference deviation distance to obtain the lighting position deviation of each working lamp bead of the target LED bulb.

[0032] Reference Figure 3As shown, the effective lighting partition of each working lamp bead in the image is cut into each effective lighting ring area according to a predefined principle, and a preset number of pixel points in each effective lighting ring area are randomly selected and recorded as each detection pixel point of each effective lighting ring area of ​​each working lamp bead. The lighting brightness and lighting chromaticity coordinates of each detection pixel point of each effective lighting ring area of ​​each working lamp bead are obtained, and compared with the lighting brightness and lighting chromaticity coordinates of the corresponding working lamp bead specified by the control instruction set, and the lighting brightness deviation and lighting chromaticity deviation of each working lamp bead are analyzed.

[0033] It should be noted that the above-mentioned predefined principle is to use the lighting position coordinates within the effective lighting area of ​​each working lamp bead as the center of the circle, and to construct each concentric ring area in increasing order with a preset radius. Each concentric ring area is numbered and sorted in order from small to large in radius, and marked as each effective lighting ring area.

[0034] The lighting position deviation, lighting brightness deviation, and lighting chromaticity deviation of each working lamp bead are sorted out to test the execution effect of the control instructions of the target LED bulb for its covered lighting area.

[0035] Specifically, the actual lighting base point coordinates of each working lamp bead effective lighting partition in the image are determined, including: converting the image into Color space, each pixel in the effective lighting area of ​​each working lamp bead is Color space Channel intensity value as its brightness amplitude ,in For the number of each working lamp bead, , is the number of each pixel in the effective lighting area, .

[0036] According to the brightness amplitude of each pixel point in the effective lighting zone of each working lamp bead, the brightness gradient amplitude of each pixel point in the effective lighting zone of each working lamp bead is analyzed.

[0037] It should be noted that the specific analysis process of the brightness gradient amplitude of each pixel point in the effective lighting zone of each working lamp bead includes: constructing the brightness amplitude matrix of each pixel point in the effective lighting zone of each working lamp bead, performing convolution operations with the preset Sobel kernel in the horizontal and vertical directions respectively, and obtaining the horizontal gradient of each pixel point in the effective lighting zone of each working lamp bead. and vertical gradient , according to the formula Obtain the brightness gradient amplitude of each pixel point in the effective lighting area of ​​each working lamp bead.

[0039] It should be noted that the specific analysis process of the chromaticity standard deviation of the unit circle domain with each pixel point as the center in the effective lighting partition of each working lamp bead is to calculate the chromaticity standard deviation of the unit circle domain with each pixel point as the center in the effective lighting partition of each working lamp bead. The channel intensity corresponds to the standard deviation, which is recorded as , according to the formula Obtain the chromaticity standard deviation of the unit circle with each pixel as the center within the effective lighting area of ​​each working lamp bead.

If the lighting position deviation, lighting brightness deviation, and lighting chromaticity deviation of a certain working lamp bead are all smaller than their corresponding preset warning thresholds, then the working lamp bead is identified as a working standard lamp bead; otherwise, the working lamp bead is identified as a working substandard lamp bead, thereby identifying each working substandard lamp bead.

[0046] The embodiment of the present invention accurately identifies the lamp beads that do not meet the standards by testing the execution effect of the control instructions of the target LED bulb for the lighting area it covers, effectively making up for the shortcomings of the existing technology in terms of the accuracy of instruction sending and the comprehensiveness of effect testing.

[0047] The lamp bead adaptive control module is used to determine the specific control objects and control parameters of each lamp bead that does not meet the working standards, and start the adaptive control process of each lamp bead that does not meet the working standards of the target LED bulb, including iterative control and control target completion logic state output.

[0048] It should be noted that the output value of the above-mentioned control target completion logic state is 1 or 0, 1 indicates that the control target is completed, and 0 indicates that the control target is not completed.

[0060] If the specific regulation object of the potential failure lamp bead is the lighting brightness and the lighting brightness regulation parameter is a positive number, then the lighting chromaticity coordinates of the potential failure lamp bead and each adjacent working qualified lamp bead are compared, it is judged whether each working qualified lamp bead adjacent to the potential failure lamp bead has the auxiliary lighting working qualification, the number of working qualified lamp beads adjacent to the potential failure lamp bead and having the auxiliary lighting working qualification is counted, the lighting brightness regulation parameter of the potential failure lamp bead is analyzed by ratio with the number of working qualified lamp beads adjacent to the potential failure lamp bead and having the auxiliary lighting working qualification, and the lighting brightness of each working qualified lamp bead adjacent to the potential failure lamp bead and having the auxiliary lighting working qualification is increased according to the above analysis, so as to carry out the auxiliary lighting work.
