Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent manufacturing of clothing, and specifically to an intelligent management system and method applied to flexible customization of clothing. Background Art
[0002] In the field of flexible customization of clothing, color management faces significant challenges in cross-device color space differences. In the traditional process, there are significant differences in the RGB color gamut coverage of cutting machines and the CMYK color gamut coverage of printing and dyeing machines, and there is a lack of a dynamic cross-device mapping mechanism, resulting in a high complaint rate of cross-device color differences for small-batch orders. When processing high-saturation colors, the color deviation problem is prominent, and multiple trial-and-error adjustments are required. At the same time, the existing static ICC profiles cannot adapt to device individual differences, aging, and changes in fabric characteristics. Changes in device status are likely to cause calibration parameters to fail, and manual recalibration takes a long time. Moreover, due to the significant differences in the light reflection characteristics of different fabrics, it is difficult for static profiles to make dynamic compensation, resulting in color differences generally exceeding the visually perceptible threshold, affecting product quality and production efficiency.
[0003] In addition, in the prior art, data in links such as cutting, printing and dyeing, and quality inspection are independent of each other, lacking means for real-time synchronization and reliable evidence storage. To trace quality problems, it is necessary to manually check multi-source data, which takes a long time to locate. Moreover, traditional databases can be tampered with, and it is difficult to define responsibilities. More critically, the existing solutions fail to build a closed-loop system of "data collection - dynamic calibration - quality traceability - algorithm evolution", lacking the ability of multi-modal data fusion, not introducing technologies such as edge computing and blockchain to solve industrial scenario requirements. Algorithm optimization relies on manual experience and cannot achieve adaptive evolution through historical data, making it difficult to cope with the frequent device adjustments and fabric replacements in flexible customization.

[0026] An intelligent management method applied to flexible customization of clothing, comprising the following steps: S1. When the fabric is put into storage, synchronously collect the spectral reflectance, RGB values, and ambient light parameters of the standard color card through a multispectral sensor and an industrial-grade RGB sensor, and construct a cross-device color reference library with timestamps and device identifiers to provide an original reference for full-process color matching; S2. Perform standardization processing on the original color data, eliminate environmental noise and device deviations through illuminance normalization correction and extreme value normalization, and then unify the gamut descriptions of the RGB of the cutting machine and the CMYK of the printing and dyeing machine through the CIE XYZ standard space to eliminate the incompatibility problem of cross-device color spaces; S3. Generate a dynamic conversion matrix exclusive to each device based on the iterative least squares optimization algorithm, convert the RGB data of the cutting machine into the theoretical CMYK values of the printing and dyeing machine, and dynamically update the matrix parameters using the gradient descent algorithm by comparing the actual output error collected by the spectrophotometer to achieve the mapping of cross-device color spaces; S4. Deploy edge computing nodes at the device end, parse the dynamic conversion matrix through a real-time operating system and update the device parameters. At the same time, combine the physical properties of the fabric thickness, gloss, and gram weight collected in real time by the sensor, and use the LSTM neural network to generate a compensation matrix to correct the change in light reflection characteristics caused by material differences and achieve real-time update of device parameters; S5. Real-time collect the operating parameters such as the temperature, pressure, speed, and ink flow of the printing and dyeing machine, combine the real-time spectral reflectance obtained by scanning the output fabric with a spectrophotometer, calculate the difference vector with the reference library spectrum, construct a multiple linear regression model, identify the causal relationship between device state fluctuations and color deviations, and provide data support for quality anomaly analysis; S6.

[0027] In the flexible customized production of clothing, the system first constructs a cross-device color reference library through a multi-source color data acquisition module. Taking a certain silk fabric as an example, with a thickness of 0.15 mm, a glossiness of 92 GU, and a gram weight of 80 g / ㎡, a multi-spectral sensor array covering a wavelength range of 400 - 700 nm with an accuracy of ±0.5% is used to collect the spectral reflectance curve of the standard color card. For example, the reflectance at 550 nm is 68%. Synchronously, through an industrial-grade RGB sensor model IMX571 with a color gamut coverage of 95% sRGB, the tristimulus values R = 185, G = 210, B = 190 are obtained, and the illuminance of 5000 Lux and the color temperature of 6500 K are collected using an ambient light sensor. The data is processed by the reference library construction unit, and with the fabric batch ID "F20230516-001" as the index, a reference data structure containing a timestamp is generated. The data is ensured to be tamper-proof through the SHA-256 hash algorithm and stored in a distributed file system. The color space preprocessing module performs illuminance normalization and extreme value normalization on the original data, converts the RGB values to CIE XYZ space coordinates X = 45.2, Y = 52.8, Z = 39.5, and calculates the corresponding CMYK coordinates through an ink overprint model to achieve the unification of the RGB color gamut of the cutting machine and the CMYK color gamut of the printing and dyeing machine, with the coincidence degree increased from 62% to 89%.
[0028] The dynamic color space mapping module generates a device-specific conversion matrix based on the iterative least squares algorithm, converting the RGB data output by the cutting machine, such as R = 200, G = 150, B = 120, into the initial values of the CMYK theoretical values for the printing and dyeing machine, which are C = 30%, M = 45%, Y = 50%, K = 0%. Comparing with the measured data of the spectrophotometer, ΔE ab = 2.7. After 5 iterations through the gradient descent algorithm, the error between the theoretical value and the measured value converges to ΔE ab = 0.9. The edge real-time calibration module deploys the FreeRTOS system through an edge computing node, with a response time ≤ 100 ms. It analyzes the dynamic matrix and writes it into the printing and dyeing machine controller. At the same time, using a three-layer architecture of the LSTM neural network with 64 neurons in each hidden layer, it analyzes the fabric characteristic vectors d = 0.15 mm, g = 92 GU, w = 80 g / ㎡ collected in real time, generates a 4×4 compensation matrix, and adjusts the ink flow parameters, such as the cyan ink flow increasing from 22 mL / min to 25 mL / min, to make the actual output color difference ΔE* ab stable within 0.8. The device status monitoring module synchronously collects parameters such as the temperature of the printing and dyeing machine at 60℃ ± 1℃ and the pressure at 0.3 MPa ± 0.02 MPa, constructs a multiple linear regression model, identifies that the temperature contributes 42% to the color deviation, and automatically adjusts the temperature control system when the warning threshold is triggered.
[0029] The full-process data closed-loop module stores all-link data through blockchain. Each block contains the conversion matrix version such as V3.2, calibration timestamp 2025-05-16 14:30:05, fabric characteristics, and equipment status, and is automatically uploaded to the chain through a smart contract, improving the data storage efficiency by 70%. The adaptive learning engine extracts more than 100,000 historical data, including 2,000 fabric characteristics and 5,000 matrix update records. Through feature engineering, the key influencing factors are screened out as the glossiness weight of 35% and the temperature weight of 28%, optimizing the LSTM model parameters and improving the generation accuracy of the compensation matrix by 30%. When the change rate of the compensation matrix for 10 consecutive predictions exceeds 5%, online fine-tuning is triggered, updating the normalization parameters and adjusting the loss function weights to form a closed-loop of acquisition-calibration-learning-evolution. In practical applications, the system improves the pass rate of cross-device color consistency from 75% to 98%, shortens the equipment calibration time from 120 minutes per time to 15 minutes per time, reduces the fabric waste rate by 22%, and realizes precise color control for small-batch customized orders such as 50 pieces per order.
