[0036] In this embodiment, the irradiance point value sequence of the light-emitting component refers to a point value sequence formed by the change of the radiation intensity of the printing laser over time within a given time interval. This point value sequence is usually plotted with the time axis as the horizontal axis and the irradiance value as the vertical axis.

[0037] In this embodiment, the optical power gain refers to the ratio of the total optical power of light to the optical power of incident light when light passes through the optical element.

[0038] In this embodiment, the correlation matrix between the optical power adjustment amount and the voltage parameter change amount of the light-emitting component is a set of data tables that describe the linear relationship between them, wherein each row corresponds to a specific voltage parameter change amount, and each column corresponds to a specific optical power adjustment amount. The correlation matrix can be used to evaluate the strength and direction of the relationship between the optical power adjustment amount and the voltage parameter change amount.

[0039] In this embodiment, the corresponding adjustment parameters of the optical power refer to some parameters that need to be changed in order to control or adjust the output power of the laser under certain conditions, such as materials and temperature.

[0045] Embodiment 3: Based on Example 2, the embodiment of the present invention obtains various data of optical power in the printing communication system according to the operation log of the printing system, pre-processes the data, and obtains the characteristics of the printing communication optical power according to the pre-processing results, such as Figure 2 As shown, including: S01: A recording method for obtaining optical power data according to an operation log of a printing system; S02: searching for various data related to optical power in the operation log according to the recording method of the optical power data; S03: Analyze the various data, and obtain the variation law of the optical power of the printing communication system according to the analysis result; S04: Determine the potential structure and relationship in the data based on the machine learning algorithm according to the change law, obtain the characteristics of the printed communication optical power according to the potential structure and relationship, and perform engineering processing.

[0046] In this embodiment, the operation log of the printing system refers to a document that records various events, states, and operations during the operation of the printing system.

[0047] In this embodiment, the optical power data is recorded in a manner including: direct measurement, indirect calculation or sensor reading.

[0048] In this embodiment, the various data related to optical power refer to a series of parameters related to optical power measurement and monitoring in an optical communication system, such as: Optical power: Indicates the optical power value output by the light source.

[0050] Optical power distortion: Indicates the degree of optical power attenuation caused by factors such as loss and reflection during the transmission of optical signals.

[0051] Wavelength: represents the length of a complete electromagnetic spectrum line segment in the propagation of light.

[0052] In this embodiment, in the printing communication system, the variation pattern of optical power is usually related to the length and loss of the optical fiber. When light passes through the optical fiber, a certain loss will occur, which will cause the intensity of the optical signal to gradually weaken. In addition, different types of optical fibers and light sources may also affect the optical power. The optical power in the printing communication system will gradually decrease with the increase of distance. This is because the propagation speed of light in the optical fiber is very fast, but when entering the optical fiber interface, the propagation direction of the light will also change due to the change in the refractive index of the medium, resulting in the loss of optical power.

[0053] In this embodiment, the characteristics of the printing communication optical power may be: light source type, wavelength range, irradiation angle, and ambient temperature.

[0054] In this embodiment, the engineering processing may be: dimensionality reduction, smoothing, and feature enhancement.

[0055] In this embodiment, the data related to optical power may include the magnitude of optical power, fluctuation range, and frequency distribution. There is a certain correlation between these data. For example, the magnitude and fluctuation range of optical power may be affected by parameters such as the type, wavelength, and current of the light source; the frequency distribution of optical power may be affected by parameters such as the material, structure, and length of the optical fiber.

[0056] The beneficial effects of the above technical solution are: obtaining various data on optical power in the printing communication system according to the operation log of the printing system, and preprocessing the data can ensure the quality and accuracy of the optical power data. At the same time, obtaining the characteristics of the printing communication optical power according to the preprocessing results can reduce the complexity of feature selection and improve the quality of the features, and at the same time, provide a basis for the subsequent construction of the model.

[0057] Embodiment 4: Based on Example 3, the embodiment of the present invention combines the characteristics of the printed communication optical power to obtain the main factors affecting the optical power, including: By calculating the correlation and weight between the characteristics of the printed communication optical power based on a statistical analysis method; The features of the printed communication optical power are combined according to the correlation degree and weight between the features to obtain a feature set; The main factors affecting the optical power are determined based on the implicit variables according to the feature set.

[0059] In this embodiment, in the printed communication system, implicit variables refer to those variables that are not directly measured but have a significant impact on the performance of other variables, such as material properties, environmental conditions, and light source characteristics.

[0060] In this embodiment, the main factors affecting the optical power may be: the material, wavelength, temperature and pressure of the light source.

[0061] The beneficial effects of the above technical solution are: combining the features of printed communication optical power according to the degree of correlation and weight of different features to obtain a feature set, and obtaining the factors affecting the optical power based on implicit variables, which can better understand the prediction results of printed communication optical power and formulate more effective measures to reduce or eliminate the impact of these factors, thereby improving printing efficiency and printing quality.

[0062] Embodiment 5: Based on Example 4, the embodiment of the present invention determines the generation mechanism of optical power and the transmission process of optical signals according to the main factors, and constructs an automated deep learning model according to the generation mechanism and the transmission process of optical signals, including: Determine the influence degree on optical power and their interaction according to the main factors; Obtain the type and working mode of the light source, and determine the generation mechanism of light power based on the degree of influence of factors on light power; Obtain the absorption and scattering of the optical signal and determine the transmission process of the optical signal based on the wavelength and refractive index; An automation-based deep learning model is constructed based on the generation mechanism and transmission process of the optical signal.

[0063] In this embodiment, in the printed communication system, the main factors affecting the optical power include: Fiber type: Different types of optical fibers have different effects on optical power. Single-mode fiber has higher optical power transmission performance than multi-mode fiber.

[0064] Length: The optical power will gradually attenuate while passing through the optical fiber, so measures need to be taken to compensate for this attenuation during long-distance transmission, such as using optical amplifiers, optical repeaters and other equipment.

[0065] Loss: In optical fiber, some losses will be generated during the propagation of light, such as absorption loss, scattering loss and bending loss.

[0066] In this embodiment, the interaction between the main factors can be: Fiber type and loss: Loss will affect the choice of fiber type. For example, if a longer transmission distance is required, you need to choose a fiber type that can withstand greater loss. At the same time, the choice of fiber type will also affect the size of the loss. For example, single-mode fiber has lower loss than multi-mode fiber.

[0067] Length and loss: The longer the length, the smaller the optical power. At the same time, loss will also affect the optical power. When the optical signal is transmitted in a long-distance optical fiber, more optical signals will be lost, resulting in a decrease in optical power.

[0068] Light source and optical fiber: The higher the power of the light source, the stronger the optical signal generated. However, the power of the light source cannot be too high, otherwise it will produce too high a light flux, resulting in distortion of the optical signal. At the same time, the optical fiber will also affect the optical signal. For example, the loss, dispersion, and reflection of the optical fiber will affect the transmission of the optical signal.

[0069] In this embodiment, the type of light source refers to the wavelength range of light emitted by the light source, including: LED lamp, HID lamp, Xenon lamp, halogen lamp.

[0074] In this embodiment, the transmission process of the optical signal refers to the process of light propagating in a medium.

At the same time, the model structure and parameters can be adaptively adjusted to adapt to different application scenarios and needs, thereby improving the generalization ability of the model and enhancing the accuracy of prediction.
