Description
Technical Field
[0001] This invention relates to the field of photovoltaic glass production, and more specifically, to a method and system for intelligent energy management and control in the production process of high-transmittance ultrathin photovoltaic glass. Background Technology
[0002] With the accelerated pace of global energy structure transformation, solar energy, as a clean and renewable energy source, has received widespread attention for its development and utilization. Photovoltaic glass, as the core encapsulation material for solar cell modules, not only provides mechanical protection and environmental isolation, but its optical performance directly affects the photoelectric conversion efficiency of photovoltaic modules. In recent years, the market demand for high-transmittance, ultra-thin photovoltaic glass has been increasing, placing higher demands on the manufacturing process of photovoltaic glass.
[0003] In the production of photovoltaic glass, the melting process is a crucial step that determines its final performance. This process involves melting, clarifying, and homogenizing the batch materials at high temperatures to form a molten glass that meets specific optical and physical performance requirements. The melting process typically takes place in a high-temperature furnace, consuming a significant amount of energy, accounting for over 70% of the total energy consumption in photovoltaic glass production. Therefore, achieving energy-efficient utilization in the melting process while ensuring high light transmittance and ultra-thin product quality has become a pressing technical challenge in the photovoltaic glass manufacturing industry.
[0004] Currently, energy management in photovoltaic glass melting processes largely relies on experience or simple heat calculations based on physical models. These methods typically estimate the required melting heat using heat balance equations based on fundamental parameters such as raw material ratios, output rates, and target temperatures. However, the actual melting process is a highly nonlinear, strongly coupled, and complex system, influenced by various dynamic factors such as furnace thermal efficiency, combustion conditions, atmosphere control, and the flow state of the molten glass. Traditional heat calculation models struggle to accurately capture these complex nonlinear relationships, leading to significant deviations in heat demand estimations. This often necessitates substantial adjustments by operators based on experience, resulting in energy waste or impacting product quality.

Detailed Implementation
[0021] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0022] like Figure 1 As shown, one embodiment of the present invention provides an intelligent energy management method for the production process of high-transmittance ultrathin photovoltaic glass, comprising: Step S110: Real-time acquisition of melting parameters and light transmittance during the photovoltaic glass melting process.
[0023] Step S120: Calculate the melting heat requirement of photovoltaic glass based on the preset melting heat calculation model and melting parameters.
[0024] Step S130: Input the melting parameters and melting heat requirements into a preset neural network. The neural network is a dual-input gated recurrent unit structure. The main path is used to input the melting parameters, the auxiliary path is used to input the melting heat requirements, the hidden layer is used to perform feature fusion on the melting parameters and melting heat requirements, and calculate the nonlinear residual term based on the fused features. The nonlinear residual term is used to represent the defect compensation of the calculation result of the melting heat calculation model.
[0025] In this embodiment, a dual-input gated recurrent unit (GRU) neural network structure is constructed. The melting heat demand calculated based on the physical model is used as an auxiliary path input, which is then fused with the main path input of the real-time acquired melting parameters in the hidden layer. This design not only preserves the interpretability and basic accuracy of the physical model, but also utilizes the powerful nonlinear fitting capability of neural networks to effectively identify and quantify the systematic biases caused by traditional heat calculation models neglecting complex dynamic factors (such as heat loss fluctuations, combustion efficiency changes, and kiln aging). By calculating and outputting nonlinear residual terms for defect compensation, dynamic correction of the initial heat demand is achieved, significantly improving the accuracy of heat demand prediction and its adaptability to actual operating conditions.
[0026] Step S140: Correct the melting heat requirement based on the nonlinear residual term.
[0027] Step S150: Detect the controllable current process parameters in the photovoltaic glass melting process.
[0028] Step S160: Based on the light transmittance and the preset target light transmittance, the current process parameters and the corresponding critical values, and the melting heat requirement, calculate the minimum melting heat requirement and the corresponding target process parameters for the photovoltaic glass to meet the target light transmittance requirement.
[0029] In this embodiment, real-time transmittance detection data and preset target values are directly incorporated into the optimization decision-making process. Taking into account the current process status, safety threshold constraints, and precise heat requirements corrected by a neural network, the minimum melting heat requirement and corresponding target process parameters are calculated to meet the high transmittance quality requirements. This breaks the traditional control model where quality assurance and energy saving are separated, achieving a closed-loop optimization goal of "achieving optimal quality with the lowest energy consumption," making it particularly suitable for the production of high-transmittance ultra-thin photovoltaic glass with stringent optical performance requirements.
[0030] Step S170: Control the energy supply of the photovoltaic glass melting process according to the target process parameters to execute the photovoltaic glass melting process.
[0031] In this embodiment, by accurately predicting and dynamically correcting the melting heat, and based on this, solving for the minimum energy consumption process scheme that satisfies quality constraints, the "overheating" phenomenon existing in traditional experience-based control can be avoided, reducing unnecessary energy waste. Executing the melting process according to the calculated optimal target process parameters ensures that energy consumption per unit product is minimized while guaranteeing product quality, significantly reducing production costs and aligning with the development direction of green manufacturing.
[0032] According to the technical solution of this embodiment, by deeply integrating the mechanism model and deep learning technology, an energy intelligent management and control system integrating precise perception, intelligent diagnosis and collaborative optimization is constructed, which effectively solves the problems of low energy efficiency and difficult quality control in the production of high-transmittance ultra-thin photovoltaic glass, and has significant economic and social benefits.
[0033] One embodiment of the present invention provides an intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process. Compared with the aforementioned embodiments, the intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process in this embodiment includes step S110: Real-time temperature monitoring of photovoltaic glass Liquid temperature change rate Raw material mass flow rate Specific heat capacity and the electro-fusion power using electrodes .
[0034] Step S120 includes: (1) According to the formula Calculate the heat of melting ,in, The preset baseline energy conversion efficiency coefficient, Indicates the production year of the electrode. This indicates that the preset electrode is subject to the production life. The attenuation coefficient of the effect Indicates the service life of the electrode. This indicates the preset electrode temperature relative to the photovoltaic glass. The attenuation coefficient of the effect The preset reference temperature, It represents the multiplication operation.
[0035] In this embodiment, by real-time acquisition of key physical parameters such as temperature, liquid temperature change rate, raw material mass flow rate, specific heat capacity, and electric melting power, a composite heat calculation formula incorporating the contributions of sensible heat absorption and effective electrical energy conversion was constructed. This formula not only considers the basic thermal energy required for material heating but, more importantly, introduces the actual conversion efficiency of electrode electrical energy to glass melt thermal energy. This upgrades the initial estimation of heat demand from a static empirical model to a dynamic physical model based on real-time operating conditions, significantly improving the scientific rigor and accuracy of the calculation starting point.
[0036] In this embodiment, an innovative nonlinear decay model for the power conversion efficiency coefficient is proposed. This model comprehensively considers the material aging caused by the service life of the electrode and the dual effects of the glass melt temperature on conductivity and heat radiation loss. This model can dynamically evaluate the actual working efficiency of the electrode at different service stages and different process temperatures, avoiding excessive or insufficient heat input due to neglecting electrode decay, thus extending the electrode's service life and ensuring the stability of the melting process.
[0037] (2) Detect the external temperature of the furnace where the photovoltaic glass is located.
[0038] (3) Calculate the nonlinear heat loss of the photovoltaic glass melting process based on the external temperature of the melting furnace, as well as the material and ventilation of the melting furnace.
[0039] (4) Based on the nonlinear heat loss of the photovoltaic glass melting process, the melting heat requirement of photovoltaic glass is corrected.
[0040] In this embodiment, the detection of external ambient temperature was added, and a nonlinear heat loss calculation model was established by combining the thermal conductivity characteristics of the furnace material and the on-site ventilation conditions. Since heat dissipation from the furnace surface is not a simple linear relationship but is affected by multiple factors such as temperature difference, wind speed, and insulation layer condition, traditional fixed heat loss coefficients are difficult to accurately reflect the actual situation. This embodiment dynamically calculates and corrects this nonlinear heat loss, making the estimation of total melting heat demand closer to the actual energy consumption and reducing control deviations caused by environmental fluctuations (such as seasonal changes, diurnal temperature differences, and changes in workshop airflow).
[0041] According to the technical solution of this embodiment, by introducing an electrode performance decay model and a nonlinear heat loss dynamic compensation mechanism, the physical calculation kernel of melting heat demand is greatly enriched and improved, so that the energy intelligent management and control method is based on a more scientific and comprehensive mechanism. This not only improves the prediction accuracy and robustness, but also provides strong technical support for the refined, green and intelligent management of high-transmittance ultra-thin photovoltaic glass production.
[0042] like Figure 2As shown, one embodiment of the present invention provides an intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process. Compared with the aforementioned embodiments, the intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process in this embodiment further includes the following steps before step S130: Step S210: Train the neural network and calculate the value of the preset loss function during the training process.
[0043] Step S220: Adjust the parameters of the main path and the auxiliary path according to the gradient change of the loss function value.
[0044] Step S230: Based on the gradient change of the loss function value, adjust the baseline power conversion efficiency coefficient. Electrodes are subject to production lifespan The attenuation coefficient of the influence The temperature of the electrodes is affected by the photovoltaic glass. The attenuation coefficient of the influence Or reference temperature Adjustments will be made.
[0045] Traditional physical models typically rely on laboratory calibration or empirical settings for key parameters, making it difficult to adapt to long-term dynamic factors in actual production, such as equipment aging, raw material fluctuations, and environmental changes. This embodiment innovatively treats these physical model parameters as learnable variables, adjusting them inversely based on changes in the loss function gradient during neural network training. This allows the physical model to continuously "self-calibrate" based on massive amounts of real-world operating data, automatically approximating the optimal parameter combination under real-world conditions, significantly improving the universality and long-term prediction accuracy of the melting heat calculation model.
[0046] According to the technical solution of this embodiment, a self-learning and self-correcting intelligent control system is constructed by introducing a joint gradient optimization mechanism of physical model parameters and neural network parameters. This system not only achieves a deeper understanding of the nonlinear characteristics of the melting process, but also significantly improves the accuracy, adaptability, and practicality of the model through bidirectional feedback between mechanisms and data. This provides an innovative technical path for the energy-efficient, stable, and intelligent control of the high-transmittance ultrathin photovoltaic glass production process.
[0047] like Figure 3 As shown, one embodiment of the present invention provides an intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process. Compared with the aforementioned embodiments, the intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process in this embodiment includes the feature fusion of melting parameters and melting heat requirements in step S130, which includes: Step S310, according to the preset time window The first eigenvector is obtained by independently linearly projecting the melting parameters of the main path. .
[0048] Step S320, according to the time window The second eigenvector is obtained by independently linearly projecting the melting heat requirement of the auxiliary path. .
[0049] Step S330, according to the time window The corresponding first feature vector Second eigenvector Calculate the time window Corresponding dynamic fusion intensity ,in For the sigmoid function, In the time window Previous time window The first feature vector generated, Used for concatenating vectors , These are the preset parameters.
[0050] In this embodiment, instead of the traditional simple splicing or fixed-weight fusion method, a dynamic fusion strength calculation method based on the sigmoid gating mechanism is proposed. This fusion strength is not fixed but is determined by the current main path features, auxiliary path features, and historical features of the main path. This design allows the system to dynamically adjust the relative importance of melting parameters (main path) and mechanistic model output (auxiliary path) in feature fusion based on real-time operating conditions and historical trends. For example, it relies more on real-time data during periods of drastic process fluctuations and trusts the calibrated physical model more during steady-state operation, thus achieving more intelligent and robust information fusion.
[0051] In this embodiment, the first feature vector of the previous time window is specifically introduced as input. This design gives the fusion decision a "memory" function, enabling it to capture the changing trends of melting parameters (such as the rate of temperature rise and the slope of electrode power adjustment). It not only focuses on the current state but also senses the dynamic evolution direction of the process, thereby predicting potential energy consumption changes or quality risks in advance and making more forward-looking compensation decisions, effectively improving the control's response speed and stability.
[0052] Step S340, according to the time window Corresponding dynamic fusion intensity For the time window The corresponding first feature vector Second eigenvector Perform feature fusion.
[0053] According to the technical solution of this embodiment, by constructing a dynamic gating fusion mechanism that integrates historical context information, intelligent and adaptive integration of main path (data-driven) and auxiliary path (mechanism-driven) information is achieved. This not only significantly improves the scientificity and effectiveness of feature fusion, but also endows the energy intelligent management and control system with stronger environmental perception, dynamic adaptability, and decision-making transparency, providing key technical support for achieving precise, efficient, and stable operation of the high-transmittance ultrathin photovoltaic glass melting process.
[0054] like Figure 4 As shown, one embodiment of the present invention provides an intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process. Compared with the aforementioned embodiments, the intelligent energy management method for the high-transmittance ultrathin photovoltaic glass manufacturing process in this embodiment further includes the following steps before step S170: Step S410: Calculate the difference between the target process parameters and the current process parameters.
[0055] Step S420: Based on the difference between the target process parameters and the current process parameters, use S-curve interpolation to generate a sequence of transition process parameters within a preset transition time.
[0056] In the melting and forming process of high-transmittance ultrathin photovoltaic glass, drastic changes in process parameters such as temperature, pressure, and edge pulling force can easily generate uneven thermal or mechanical stress within the glass, leading to defects such as microcracks, warping, and excessive waviness, severely affecting the product's light transmittance and mechanical strength. In this embodiment, by calculating the difference between the target process parameters and the current process parameters, and using S-curve interpolation to generate a sequence of transitional process parameters, the parameter adjustment process exhibits a smooth characteristic of "slow start, stable middle, and gentle finish," avoiding the impact of step changes and fundamentally reducing the quality risks induced by process abrupt changes, thus significantly improving product yield.
[0057] The transition time can be calculated as follows: (1) Detect the thickness and transmission speed of photovoltaic glass.
[0058] (2) Calculate the speed-to-thickness ratio of the photovoltaic glass based on its thickness and transmission speed, which is used to represent the tensile strain rate per unit thickness of the photovoltaic glass.
[0059] (3) Based on the temperature of the photovoltaic glass Calculate the temperature change rate of the photovoltaic glass.
[0060] (4) Calculate the maximum stress change rate of photovoltaic glass based on the speed-to-thickness ratio and temperature change rate of photovoltaic glass, which is used to represent the stress growth rate of photovoltaic glass per unit time.
[0061] (5) Set the transition time according to the maximum stress change rate of the photovoltaic glass.
[0062] This embodiment abandons the crude approach of fixed transition time and proposes an intelligent strategy that dynamically calculates the transition time based on the real-time status of photovoltaic glass. By detecting glass thickness, conveying speed, temperature, and temperature change rate, key physical indicators such as "speed-to-thickness ratio" (characterizing tensile strain rate) and "maximum stress change rate" (characterizing stress growth rate per unit time) are calculated. Based on these, the ability of the glass to withstand stress changes under current operating conditions is assessed, and a safe and reasonable transition time is automatically set. For example, when the glass is thin, the speed is high, or the temperature gradient is large, the transition time is automatically extended to ensure slow stress release, achieving true "on-demand adjustment."
[0063] Step S430: During the transition time, perform the photovoltaic glass melting process according to the transition process parameter sequence.
[0064] After the transition time, proceed to step S170.
[0065] According to the technical solution of this embodiment, by introducing an intelligent transition control mechanism based on S-curve interpolation and dynamic stress assessment, the physical properties of materials are deeply integrated into the process control logic, achieving a closed-loop upgrade from "static optimization" to "dynamic and stable execution." This technology not only effectively solves the quality problems caused by process jumps in the production of high-transmittance ultra-thin photovoltaic glass, but also improves production efficiency while ensuring high product quality through adaptive and refined transition management, providing key process execution guarantees for intelligent manufacturing of photovoltaic glass.
[0066] One embodiment of the present invention provides a method for intelligent energy management in the production process of high-transmittance ultrathin photovoltaic glass. Compared with the foregoing embodiments, the method for intelligent energy management in the production process of high-transmittance ultrathin photovoltaic glass in this embodiment further includes: (1) The vibration frequency of the furnace is detected by a vibration sensor deployed on the furnace.
[0067] (2) Detect abnormal points on the furnace using infrared equipment.
[0068] (3) Determine the fault of the furnace based on the vibration frequency and abnormal points of the furnace.
[0069] In this embodiment, by deploying vibration sensors to monitor the resonant frequency shift of the furnace structure in real time, and combining this with infrared equipment to detect local abnormal high-temperature points, potential equipment hazards can be detected in advance.
[0070] (4) When the fault of the furnace is determined to be a structural resonance frequency shift, the energy supply of the furnace will be reduced according to the preset first limit, and the preset backup pump will be activated to supply energy.
[0071] (5) When it is determined that the fault of the furnace is a defect in the transmission component, the energy supply of the furnace is reduced according to the preset second limit, and the preset diesel generator is activated to supply energy. The second limit is higher than the first limit.
[0072] According to the technical solution of this embodiment, a differentiated energy supply strategy is adopted for different fault types: when the structure resonates and shifts, the energy supply is adjusted according to the preset first limit (such as a reduction of 10%-15%) and the backup pump is switched to avoid equipment overload damage; when the transmission component is defective, the load is reduced according to the higher second limit (such as a reduction of 20%-25%), and the diesel generator is activated to maintain the stability of key process parameters to prevent serious accidents such as glass liquid solidification caused by sudden power failure.

[0102] Demand module 520 calculates the melting heat requirement of photovoltaic glass based on the preset melting heat calculation model and melting parameters.
[0103] The residual module 530 inputs the melting parameters and melting heat requirements into a preset neural network. The neural network is a dual-input gated recurrent unit structure, in which the main path is used to input the melting parameters and the auxiliary path is used to input the melting heat requirements. The hidden layer is used to perform feature fusion on the melting parameters and melting heat requirements, and calculates nonlinear residual terms based on the fused features. The nonlinear residual terms are used to represent the defect compensation of the calculation results of the melting heat calculation model.
[0104] In this embodiment, a dual-input gated recurrent unit (GRU) neural network structure is constructed. The melting heat demand calculated based on the physical model is used as an auxiliary path input, which is then fused with the main path input of the real-time acquired melting parameters in the hidden layer.

Taking into account the current process status, safety threshold constraints, and precise heat requirements corrected by a neural network, the minimum melting heat requirement and corresponding target process parameters are calculated to meet the high transmittance quality requirements. This breaks the traditional control model where quality assurance and energy saving are separated, achieving a closed-loop optimization goal of "achieving optimal quality with the lowest energy consumption," making it particularly suitable for the production of high-transmittance ultra-thin photovoltaic glass with stringent optical performance requirements.
[0109] The melting module 570 controls the energy supply for the photovoltaic glass melting process according to the target process parameters in order to execute the photovoltaic glass melting process.
[0110] In this embodiment, by accurately predicting and dynamically correcting the melting heat, and based on this, solving for the minimum energy consumption process scheme that satisfies quality constraints, the "overheating" phenomenon existing in traditional experience-based control can be avoided, reducing unnecessary energy waste. Executing the melting process according to the calculated optimal target process parameters ensures that energy consumption per unit product is minimized while guaranteeing product quality, significantly reducing production costs and aligning with the development direction of green manufacturing.
