[0002] The lightweighting process of glass bottles faces numerous technical bottlenecks, including the contradiction between strength and weight, insufficient molding precision, and reliance on experience for quality control. Under traditional processes, the internal pressure resistance decreases significantly after the bottle wall is thinned, resulting in a high breakage rate in drop tests and large errors in wall thickness uniformity, leading to a low pass rate.
[0003] Existing technologies also have limitations: Offline and Non-Real-Time: Optimization of process parameters relies heavily on pre-production simulation and post-production testing, making real-time, proactive adjustments during production impossible. Information Silos: There is a lack of deep integration and collaborative analysis between equipment status, process parameters, and product quality data. Feedback control is mostly limited to localized fine-tuning, making global optimization difficult. Traditional Methods Rely on Physical Trial and Error: For new bottle types or equipment layouts, companies need to spend significant time and materials on physical debugging, resulting in high costs and long cycles.
[0004] Therefore, there is a need for a system and method that can closely integrate software simulation with hardware production to achieve end-to-end, self-learning, and dynamic optimization. Summary of the Invention

[0023] The energy consumption and resource monitoring unit is equipped with smart meters and gas flow meters at key nodes such as the furnace, air compressor, and annealing furnace to monitor energy consumption data in real time.
[0024] By adopting the above structure, real-time and accurate energy data collection is carried out on key energy-consuming nodes such as pool kilns, air compressors, and annealing furnaces. This provides a precise data foundation for energy efficiency optimization, cost accounting, and carbon footprint management of the entire system, which is a key link in realizing green manufacturing and refined energy management.
[0025] The data transmission unit uses 5G / industrial Ethernet communication to upload data to the dynamic feedback optimization unit in real time.
[0026] The above structure serves as an "information highway" connecting physical devices and digital systems. By utilizing high-bandwidth, low-latency communication technologies such as 5G / Industrial Ethernet, real-time collected production data is stably and efficiently uploaded to the dynamic feedback optimization unit, providing reliable data flow assurance for the system's real-time analysis, decision-making, and closed-loop control.

[0029] The carbon footprint accounting unit connects to the EU EPDR and the domestic dual-carbon regulatory platform to meet compliance requirements. Based on the raw material carbon emission database, equipment energy consumption carbon emission coefficient and transportation carbon emission model, it calculates the carbon footprint of a single bottle in real time and generates a carbon footprint report.
[0030] By adopting the above structure and integrating internal and external carbon emission factor databases, the carbon emission data of a single glass bottle product can be quantified and tracked in real time and accurately throughout its entire life cycle. At the same time, it automatically generates carbon footprint reports that comply with domestic and international regulations, providing key data support for optimizing carbon emissions in the production process and achieving green compliance for enterprises.

[0032] Using the above structure, a high-fidelity digital twin is constructed and driven. Through comprehensive modeling of integrated equipment geometry, process logic, multiphysics, and material properties, the entire glass bottle production process is accurately reproduced and simulated in a virtual environment. This enables forward-looking prediction and evaluation of product performance, potential defects, and production feasibility, providing an accurate simulation basis and scientific evidence for subsequent process optimization.
[0033] The software simulation optimization unit is used to pre-optimize the equipment layout, dimensions, and molding process parameters, including: Information input subunit: Receives equipment 3D model information, equipment operating parameter information, multi-material physical performance parameters, and environmental parameters. The equipment 3D model information covers the structural dimensions, assembly relationships, and material parameters of the furnace, feeder, forming machine, annealing furnace, and testing equipment. The equipment operating parameter information includes glass melting temperature, blowing pressure range, mold opening and closing speed, and annealing cooling rate. The multi-material physical performance parameters cover the melting point, viscosity-temperature curve, and strength index of ordinary glass, glass-ceramic composite materials, nano-SiO2 reinforced glass, and lead-free environmentally friendly glass. Simulation Analysis Subunit: Based on the entered information, a virtual production environment is constructed, a 1:1 digital twin of the physical production line, simulating the entire processing of glass bottles from raw material melting, initial molding, shaping and strengthening, annealing to inspection. ANSYS finite element analysis software is used to perform stress analysis and process bottleneck identification on the initial blank and finished bottle, focusing on optimizing the stress concentration area at the bottom of the bottle. An LSTM long short-term memory network model and reinforcement learning algorithm are embedded to train a quality prediction model, enabling advanced prediction and evaluation of key quality indicators, with predictions possible 5-10 seconds in advance. Simultaneously, the collaborative working status of various electrical components is analyzed, process connection bottlenecks are identified, and the interval time between each process step is optimized to minimize process connection time. Coupled analysis of process parameters is performed, simulating the interaction between glass melt temperature, blowing pressure, and cooling time through iterative simulation. Output subunit: Through multiple rounds of simulation iteration, it outputs the optimal processing equipment size, layout scheme, and molding process parameters. The process parameters include raw material ratio, melting temperature, molding temperature, initial blowing pressure curve, final blowing pressure, mold opening and closing speed, annealing temperature curve, cooling rate, and time nodes of each process, ensuring that the process interval is minimized and the coupling interference of process parameters is minimized; it outputs the Pareto optimal solution and the carbon footprint pre-control target. Transfer learning sub-unit: When switching bottle type or material, the system can reuse the training model of similar products, and only needs to fine-tune the model with a small amount of new data, shortening the debugging cycle to 2-3 days; establish a standardized mold library and parameter library linkage mechanism.
[0034] By adopting the above structure, a digital twin that is completely consistent with the physical production line is constructed. By integrating multiphysics simulation and AI algorithms, multiple rounds of iterative optimization and forward-looking prediction of equipment layout, process parameters and production process are carried out in a virtual environment. Finally, the optimal production plan that takes into account quality, efficiency, energy consumption and carbon footprint is output, and transfer learning support is provided for rapid production changeover. Thus, the system performance can be accurately designed and continuously optimized before it is put into actual production.
[0035] The dynamic feedback optimization unit is communicatively connected to the software simulation optimization unit, the hardware execution module, and the global data perception module. It uses a PLC and a central controller to construct the control logic. Its reinforcement learning algorithm uses the highest pass rate, lowest energy consumption, lowest cost, and lowest carbon footprint as multi-objective reward functions to automatically iterate and optimize the combination of process parameters. It integrates AI algorithms to achieve adaptive parameter adjustment, defect tracing, and predictive equipment maintenance. The dynamic feedback optimization unit includes: Data distribution subunit: Distributes the optimal set of process parameters obtained by the optimization engine to the central controller of the hardware execution module to guide actual production, and receives equipment status and product quality information uploaded by the equipment working status sensor network unit in real time during the production process; Data comparison and analysis subunit: compares the real-time collected equipment status data and material quality data with the preset parameters output by the software simulation and optimization unit to identify deviations; Parameter Adaptive Adjustment Subunit: When a deviation is detected, parameters are automatically fine-tuned based on reinforcement learning algorithms: If the wall thickness uniformity is unqualified, the pressure of the corresponding side blowing head or the mold closing gap is adjusted; if the glass melt viscosity change leads to poor initial blowing effect, the coefficients k and b in the initial blowing pressure formula P1=kln(μ)+b are updated, where k and b are adjustable coefficients determined by automatic iterative optimization based on reinforcement learning algorithms, historical production data, and real-time detected glass melt viscosity changes. The initial values of k and b are determined by the software simulation optimization unit through iterative pre-optimization using digital twin simulation. The updated values in actual production are automatically calculated and generated by the reinforcement learning model based on real-time detected glass melt viscosity and product quality feedback, and the optimized parameters are fed back to the simulation model parameter library to achieve closed-loop self-learning optimization. μ is the glass melt viscosity; if the residual stress after annealing exceeds the standard, the cooling rate of the annealing furnace or equipment parameters are adjusted; if the carbon footprint exceeds the standard, the crushed glass ratio is increased or the tank furnace temperature is reduced; if the energy consumption is too high, the annealing cooling rate or tank furnace insulation power is optimized. Predictive maintenance subunit: Based on LSTM algorithm, analyze equipment vibration, temperature and wear data to predict the remaining life of the equipment and generate maintenance suggestions; establish equipment maintenance knowledge base to record fault causes and solutions, forming a prediction-maintenance-feedback closed loop; Model and parameter library update sub-unit: Feeds back the adjusted optimal parameters to the software simulation optimization unit, updates the parameter library of the simulation model, and provides accurate basic data for pre-optimization in subsequent production. Early warning and traceability sub-unit: Sets multi-level parameter threshold early warning, including quality threshold and carbon footprint threshold. When equipment parameters exceed the safe range or the material non-conforming rate exceeds 5% for three consecutive times, it triggers an audible and visual alarm and suspends production. Operation resumes after the parameters are adjusted to meet the requirements. In case of sudden failure, it automatically executes emergency adjustment logic to ensure that the non-conforming rate does not exceed 1%. The data server records equipment operation logs, process parameter adjustment records, and material quality information, with a traceability period of not less than 1 year, which facilitates fault diagnosis and process iteration.
[0036] By adopting the above structure, production data and simulation preset values are compared in real time. AI algorithms such as reinforcement learning are used to automatically diagnose deviations, trace defects, and dynamically adjust process parameters. At the same time, predictive maintenance of equipment and system early warning are carried out. Finally, the optimal parameters verified in practice are fed back to update the simulation model, forming an adaptive optimization closed loop of "perception-decision-execution-learning" that runs through the virtual and physical worlds, continuously improving the quality, efficiency and greenness of production.
[0037] The supply chain collaboration interface unit is not limited to connecting to enterprise ERP systems to obtain order information. For new bottle type orders, the platform can conduct virtual trial production and production changeover simulations in advance, providing a basis for accurate production scheduling.
[0038] The above structure serves as a bridge connecting the production system and enterprise information management. By connecting with upper-level systems such as ERP to obtain order data, and using digital twin technology to conduct virtual trial production and changeover simulation for new orders, business needs are transformed into accurate and feasible production plans, thereby achieving efficient and scientific collaboration from order to production scheduling.

[0040] By adopting the above structure and utilizing QR code and blockchain technology, a unique and tamper-proof "digital ID card" is established for each product batch. This allows for the complete and reliable recording and association of data across the entire chain, from raw materials and production to logistics, thereby enabling precise traceability of quality, rapid identification of responsibility for problems, and transparent management of the production process.
[0041] The carbon footprint and cost accounting unit automatically calculates the carbon emissions and production costs per unit of product based on real-time energy consumption and material data, providing data support for green manufacturing and refined management.
[0042] By adopting the above structure, and through the automatic collection and correlation of real-time production data, the resource consumption, carbon emissions and cost composition of each unit product can be accurately quantified, providing enterprises with quantifiable decision-making basis for implementing green manufacturing transformation and refined cost control, and achieving a balance between economic and environmental benefits.
[0043] The AR operation and maintenance unit is equipped with AR glasses that operators can wear, enabling them to view the internal status of the equipment, parameter deviations, and maintenance instructions in real time, thus lowering the barrier to operation and maintenance.
[0044] By adopting the above structure and using augmented reality technology, digital information such as the internal status of the equipment, real-time parameters, and maintenance instructions can be intuitively overlaid on the physical view, realizing the visualization of key operation and maintenance information. This reduces the reliance on personnel experience, improves the accuracy and efficiency of maintenance operations, and effectively lowers the operation and maintenance threshold.
[0045] The remote monitoring unit allows managers to view production line operation data in real time via PC or mobile device, and managers can remotely issue adjustment instructions.
[0046] By adopting the above structure, the limitations of physical space are broken, and the core indicators of the production line (output, pass rate, energy consumption, carbon footprint) are displayed in real time through multiple terminals. In case of anomalies, early warnings are pushed out proactively, enabling managers to grasp the production status anytime and anywhere and make remote interventions (such as parameter fine-tuning and emergency shutdown), thereby greatly improving the management response speed and decision-making efficiency.
[0047] When production efficiency or pass rate declines, the operator can trigger the one-click optimization unit. The system will automatically call the digital twin and AI algorithm to output the optimal parameters and perform adjustments.
[0048] By adopting the above structure, the complex system optimization process is simplified into a "one-click" operation. When production efficiency or pass rate declines, the system can automatically call the digital twin and AI algorithm for rapid diagnosis and global optimization, and automatically perform parameter adjustments. This significantly reduces the technical threshold and time cost of optimization operations, and quickly restores and ensures the optimal operating state of the production system.
[0049] The hierarchical access control unit sets three levels of permissions: operators, administrators, and R&D personnel. Operators can only view operation-related parameters, administrators can view all data, and R&D personnel can only access the simulation model to prevent the leakage of core technologies.
[0050] By adopting the above structure and dividing permissions into three levels—operators, managers, and R&D personnel—layered control of data and functions can be achieved. This ensures system information security, effectively isolates the core simulation model from the production site, prevents the leakage of key technologies, and ensures that each type of user can only access data and functions within their scope of responsibility.
[0051] The data security protection unit performs regular data backups and security audits, in compliance with relevant data security regulations.
[0052] By adopting the above structure and implementing two key measures—regular data backup and security audit—the integrity, availability, and compliance of system data are ensured, data loss and security risks are effectively prevented, and the requirements of laws and regulations such as the "Data Security Law" and the "Administrative Measures for Industrial Data Security" are met, providing reliable data security guarantees for the stable operation of the entire platform.
[0053] Compared with existing technologies, this optimized lightweight glass bottle molding process system has the following advantages: This system uses digital twin technology for virtual simulation and AI pre-optimization to accurately set the optimal process parameters. Combined with a five-dimensional full-process quality inspection system, it enables switching between multiple bottle types and materials to ensure product wall thickness uniformity, high strength, and low defect rate.
[0054] This system significantly reduces production energy consumption through intelligent power regulation, waste heat recovery, and energy consumption monitoring. The AI algorithm-driven parameter optimization and cost accounting modules enable refined management of raw materials and energy, further reducing costs.
[0055] This system constructs a complete closed loop of "perception-decision-execution-feedback". The dynamic feedback optimization unit can automatically adjust process parameters and predict equipment maintenance based on real-time production data using reinforcement learning algorithms, and feed back the verified optimal parameters to the simulation model, enabling the system to have continuous evolution capabilities and ensuring that production is always in the optimal state.
[0056] This system integrates carbon footprint accounting, accurately tracks the carbon footprint of a single bottle, and generates compliance reports, effectively supporting enterprises in achieving their "dual carbon" goals.

[0091] The carbon footprint accounting unit connects to the EU EPDR and the domestic dual-carbon regulatory platform to meet compliance requirements. Based on the raw material carbon emission database, equipment energy consumption carbon emission coefficient, and transportation carbon emission model, it calculates the carbon footprint of a single bottle in real time. It connects to the raw material carbon emission database (such as 0.15kg / kg of quartz sand and 0.8kg / kg of soda ash), the equipment energy consumption carbon emission coefficient (such as 0.6kg / kWh of electricity), and the transportation carbon emission model (calculated by distance and load) to generate a carbon footprint report.
[0092] By integrating internal and external carbon emission factor databases, the system can quantify and track the carbon emission data of individual glass bottle products throughout their entire life cycle in real time and with high accuracy. It can also automatically generate carbon footprint reports that comply with domestic and international regulations, providing key data support for optimizing carbon emissions in the production process and achieving green compliance for enterprises.
[0093] The virtual simulation unit includes: Equipment modeling sub-unit: Based on the entered 3D equipment information, construct a high-fidelity virtual production line; Process modeling sub-unit: Based on the input equipment working information (such as the blowing pressure curve P1=kln(μ)+b, mold opening and closing speed, temperature setting), the entire glass bottle processing process is simulated in a virtual environment; Physics-field coupling analysis sub-unit: Integrating computational fluid dynamics and finite element analysis, it performs high-precision simulation of the flow, temperature distribution, forming process and stress evolution of molten glass during the simulation process, and predicts wall thickness uniformity, structural strength and potential defects (such as uneven wall thickness and stress concentration). Material property library sub-unit: It contains glass material models with different proportions (such as 25%-35% quartz glass, 1-3% ZrO2, 0.5-1.5% Li2O), which accurately reflect their thermophysical and rheological properties.
[0094] By constructing and driving a high-fidelity digital twin, and through comprehensive modeling of equipment geometry, process logic, multiphysics, and material properties, the entire glass bottle production process can be accurately reproduced and simulated in a virtual environment. This enables forward-looking prediction and evaluation of product performance, potential defects, and production feasibility, providing a precise simulation basis and scientific evidence for subsequent process optimization.
[0095] The software simulation optimization unit is used to pre-optimize equipment layout, dimensions, and molding process parameters, including: Information input subunit: Receives equipment 3D model information, equipment operating parameter information, physical performance parameters of multiple materials, and environmental parameters. The equipment 3D model information covers the structural dimensions, assembly relationships, and material parameters of the furnace, feeder, forming machine, annealing furnace, and testing equipment. The equipment operating parameter information includes the glass melting temperature, blowing pressure range, mold opening and closing speed, and annealing cooling rate. The physical performance parameters of multiple materials cover the melting point, viscosity-temperature curve, and strength index of ordinary glass, glass-ceramic composite materials, nano-SiO2 reinforced glass, and lead-free environmentally friendly glass. The simulation analysis subunit constructs a virtual production environment based on a 1:1 digital twin of the physical production line using entered information. It simulates the entire glass bottle manufacturing process, from raw material melting, initial molding, shaping and strengthening, annealing to inspection. ANSYS finite element analysis software is used to perform stress analysis and process bottleneck identification on the initial preform and finished bottle, focusing on optimizing the stress concentration area at the bottle bottom. An LSTM long short-term memory network model and reinforcement learning algorithm are embedded to train a quality prediction model, enabling advanced prediction and evaluation of key quality indicators, with predictions possible 5-10 seconds in advance. Simultaneously, the unit analyzes the collaborative working status of various electrical components (servo motors, temperature controllers, pressure controllers), identifies process connection bottlenecks, optimizes the interval time between process steps, and minimizes process connection time. Coupled analysis of process parameters is performed, simulating the iterative effects of glass melt temperature, blowing pressure, and cooling time. Output subunit: Through multiple rounds of simulation iteration, it outputs the optimal processing equipment size, layout scheme (such as mold spacing, material transfer path) and molding process parameters. The process parameters include raw material ratio, melting temperature (1500-1550℃), molding temperature (1150-1250℃), initial blowing pressure curve (P1=kln(μ)+b, k and b are simulation optimization coefficients, P1=0.28-0.32MPa), final blowing pressure (0.48-0.52MPa), mold opening and closing speed (accuracy ±1mm / s), annealing temperature curve, cooling rate (15%-25% lower than traditional process), and time nodes of each process, ensuring that the process interval is minimized and the coupling interference of process parameters is minimized; it outputs the Pareto optimal solution of "energy consumption-quality-carbon footprint" and the carbon footprint pre-control target (such as single bottle carbon footprint ≤0.5kgCO2e). In the transfer learning sub-unit, when switching bottle types or materials, the system can reuse the training model of similar products, requiring only a small amount of new data for model fine-tuning, shortening the debugging cycle to 2-3 days; a standardized mold library and parameter library linkage mechanism is established to adapt to 50-1000ml capacity, round / square / irregular shapes and more than 10 kinds of bottle types, as well as the production of multiple materials such as ordinary glass and glass-ceramic composite materials.
[0096] By constructing a digital twin that is completely consistent with the physical production line, and integrating multiphysics simulation and AI algorithms, the system performs multiple rounds of iterative optimization and forward-looking prediction of equipment layout, process parameters and production flow in a virtual environment. Ultimately, it outputs the optimal production solution that takes into account quality, efficiency, energy consumption and carbon footprint, and provides transfer learning support for rapid production changeover. This allows for precise design and continuous optimization of system performance before it is put into actual production.
[0097] The dynamic feedback optimization unit communicates with the software simulation optimization unit, hardware execution module, and global data perception module. It uses a PLC and central controller to construct the control logic. Its reinforcement learning algorithm uses a multi-objective reward function of "highest pass rate + lowest energy consumption + lowest cost + lowest carbon footprint" to automatically iteratively optimize process parameter combinations. It integrates AI algorithms to achieve adaptive parameter adjustment, defect tracing, and predictive equipment maintenance. The dynamic feedback optimization unit includes: Data distribution subunit: Distributes the optimal set of process parameters obtained by the optimization engine to the central controller of the hardware execution module to guide actual production, and receives "equipment status" and "product quality" information uploaded by the equipment working status sensor network unit in real time during the production process; Data comparison and analysis subunit: Compares the real-time collected equipment status data and material quality data with the preset parameters output by the software simulation and optimization unit to identify deviations (such as wall thickness exceeding ±0.02mm, blowing pressure deviating from the preset range, and equipment temperature fluctuation exceeding ±5℃). Parameter adaptive adjustment subunit: When a deviation is detected, parameters are automatically fine-tuned based on a reinforcement learning algorithm: If the wall thickness uniformity is unqualified, the pressure of the corresponding side blowing head or the mold closing gap is adjusted; if the glass melt viscosity change leads to poor initial blowing effect, the coefficients k and b in the initial blowing pressure formula P1=kln(μ)+b are updated, where k and b are adjustable coefficients determined by automatic iterative optimization based on reinforcement learning algorithm according to historical production data and real-time detected glass melt viscosity changes. The initial values of k and b are determined by the software simulation optimization unit through iterative pre-optimization using digital twin simulation. The updated values are automatically generated by the reinforcement learning model based on the real-time detection of the glass melt viscosity and product quality feedback. The optimized parameters are then fed back to the simulation model parameter library to achieve closed-loop self-learning optimization. μ is the glass melt viscosity. If the residual stress exceeds the standard after annealing, adjust the annealing furnace cooling rate or equipment parameters (mold closing gap, servo motor control accuracy). If the carbon footprint exceeds the standard, the cullet glass content can be increased to the upper limit allowed by the process (e.g., 35%) or the tank furnace temperature can be reduced (10-20℃). If the energy consumption is too high, optimize the annealing cooling rate or the tank furnace insulation power. Predictive maintenance subunit: Based on LSTM algorithm, analyze equipment vibration, temperature and wear data to predict the remaining life of the equipment (e.g., warning when the remaining life of the mold wear is ≥5000 cycles), generate maintenance suggestions (e.g., mold grinding, motor oil change); establish equipment maintenance knowledge base, record fault causes and solutions, and form a closed loop of "prediction-maintenance-feedback"; Model and parameter library update sub-unit: Feeds back the adjusted optimal parameters to the software simulation optimization unit, updates the parameter library of the simulation model, provides accurate basic data for the pre-optimization of subsequent production, and realizes closed-loop adaptive optimization of process and equipment; Early warning and traceability sub-unit: Sets multi-level parameter threshold early warning, quality threshold (e.g., wall thickness ±0.02mm), carbon footprint threshold (e.g., ≤0.5kgCO2e / bottle). When equipment parameters exceed the safe range or the material non-conforming rate exceeds 5% for three consecutive times, an audible and visual alarm is triggered and production is suspended. Operation resumes after the parameters are adjusted to be within acceptable limits. In case of sudden failure, emergency adjustment logic is automatically executed (e.g., reducing production speed, stabilizing blowing pressure) to ensure that the non-conforming rate does not exceed 1%. The data server records equipment operation logs, process parameter adjustment records, and material quality information, with a traceability period of no less than one year, facilitating fault diagnosis and process iteration.
[0098] By comparing production data with simulation presets in real time, AI algorithms such as reinforcement learning are used to automatically diagnose deviations, trace defects, and dynamically adjust process parameters. At the same time, predictive maintenance of equipment and system early warning are carried out. Finally, the optimal parameters verified in practice are fed back to update the simulation model, forming an adaptive optimization closed loop of "perception-decision-execution-learning" that runs through the virtual and physical worlds, continuously improving the quality, efficiency and greenness of production.
[0099] The supply chain collaboration interface unit can connect to various systems beyond just enterprise ERP systems to obtain order information. For orders of new bottle types, the platform can conduct virtual trial production and production changeover simulations in advance, providing a basis for accurate production scheduling.
[0100] As a bridge connecting the production system and enterprise information management, it obtains order data by connecting with upper-level systems such as ERP, and uses digital twin technology to conduct virtual trial production and production changeover simulation for new orders, transforming business needs into accurate and feasible production plans, thereby achieving efficient and scientific collaboration from order to production scheduling.
[0101] The full lifecycle quality traceability unit assigns a unique QR code to each product batch, linking it to the entire chain of data from raw material formula, process parameters, test results to outgoing logistics, forming an immutable quality blockchain.
[0102] By using QR codes and blockchain technology, a unique and tamper-proof "digital ID card" is created for each product batch, which completely and reliably records and links its data from raw materials and production to logistics, thereby achieving precise traceability of quality, rapid determination of responsibility for problems, and transparent management of the production process.
[0103] The carbon footprint and cost accounting unit automatically calculates the carbon emissions and production costs per unit of product based on real-time energy consumption and material data, providing data support for green manufacturing and refined management.
[0104] By automatically collecting and linking real-time production data, the resource consumption, carbon emissions, and cost composition of each unit product can be accurately quantified, providing enterprises with quantifiable decision-making basis for implementing green manufacturing transformation and refined cost control, thereby achieving a balance between economic and environmental benefits.
[0105] The AR maintenance unit is equipped with AR glasses that operators can wear to view the internal status of the equipment (such as mold wear), parameter deviations, and maintenance instructions (such as mold disassembly steps) in real time, thus lowering the barrier to maintenance.
[0106] Augmented reality technology is used to intuitively overlay digital information such as the internal status of equipment, real-time parameters, and maintenance instructions onto the physical field of view, thereby visualizing key operation and maintenance information, reducing reliance on personnel experience, improving the accuracy and efficiency of maintenance operations, and effectively lowering the threshold for operation and maintenance.
[0107] The remote monitoring unit allows managers to view production line operation data (output, pass rate, energy consumption, carbon footprint) in real time via PC and mobile devices. It pushes early warning information (SMS, APP notification) when anomalies occur, and managers can remotely issue adjustment instructions (emergency shutdown, parameter fine-tuning).
[0108] Breaking the limitations of physical space, the system displays core production line indicators (output, pass rate, energy consumption, carbon footprint) in real time through multiple terminals and proactively pushes early warnings when anomalies occur. This enables managers to grasp the production status anytime, anywhere and make remote interventions (such as parameter fine-tuning and emergency shutdown), thereby greatly improving management response speed and decision-making efficiency.
[0109] When production efficiency or yield rate declines, operators can trigger one-click optimization. The system automatically calls up the digital twin and AI algorithm to output the optimal parameters and perform adjustments.
[0110] The complex system optimization process is simplified into a "one-click" operation. When production efficiency or pass rate declines, the system can automatically call upon digital twins and AI algorithms for rapid diagnosis and global optimization, and automatically adjust parameters. This significantly reduces the technical threshold and time cost of optimization operations, and quickly restores and ensures the optimal operating state of the production system.
[0111] The hierarchical access control unit sets up three levels of permissions: operators, administrators, and R&D personnel. Operators can only view operation-related parameters, administrators can view all data, and R&D personnel can only access the simulation model, preventing the leakage of core technologies. By dividing permissions into three levels, layered control of data and functions is achieved. This ensures system information security while effectively isolating the core simulation model from the production site, preventing the leakage of key technologies, and ensuring that each type of user can only access data and functions within their scope of responsibility.
[0112] The data security protection unit regularly performs data backups and security audits, complying with relevant data security regulations. By regularly implementing these two key measures, the integrity, availability, and compliance of system data are ensured, effectively preventing data loss and security risks. This meets the requirements of regulations such as the "Data Security Law" and the "Industrial Data Security Management Measures," providing reliable data security assurance for the stable operation of the entire platform.

After training with historical data, the LSTM model predicted that the wall thickness deviation of the initial blank would be ≤±0.01mm. The reinforcement learning algorithm iteratively optimized the formula for initial blowing pressure, P1=0.05ln(μ)+0.25, final blowing pressure, and annealing cooling rate of 5℃ / min (20% lower than the traditional method). The energy consumption simulation output melting temperature of 1520℃ was the optimal solution for "energy consumption-mass". Flexible parameter output: linear layout of equipment for 500ml liquor bottles (spacing 1.5m-2.0m), mold parameters and process adjustment scheme for 300ml irregular-shaped bottles (initial blowing pressure 0.3MPa, final blowing pressure 0.52MPa), mold changing adaptation parameters (automatic mold changing robot path planning); carbon footprint pre-control target is ≤0.45kg / bottle.

The robot changes the mold of the irregular bottle according to the digital twin planning path. The mold change time is 4.5 minutes. The software automatically calls up the process parameters of the irregular bottle and adjusts the furnace temperature to 1550℃ to adapt to the glass-ceramic composite material.
[0123] 3. Real-time data acquisition and dynamic optimization Data acquisition: Real-time acquisition of glass melt viscosity μ=1000Pa·s (liquor bottle) / 1200Pa·s (irregularly shaped bottle), initial blowing pressure 0.3MPa / 0.32MPa, wall thickness uniformity ±0.015mm / ±0.018mm, single bottle carbon footprint 0.43kg / 0.48kg, equipment vibration value 0.2mm / s, and mold wear 0.01mm; Dynamic adjustment: When the carbon footprint of the irregularly shaped bottle is close to the threshold of 0.48 kg, the system automatically increases the proportion of crushed glass from 30% to 35%, and the carbon footprint is reduced to 0.46 kg after adjustment; when a slight burr is detected at the mouth of the irregularly shaped bottle, the closing gap of the shaping mold is associated with it and reduced by 0.01 mm, the defect is eliminated. Equipment maintenance warning: When the cumulative wear of the mold reaches 0.05mm, the system predicts that the remaining lifespan is 8000 cycles and pushes a grinding and maintenance suggestion.
[0124] 4. Human-machine collaboration and full lifecycle traceability Operation and maintenance: Operators use AR glasses to check the wear of the molds and complete the polishing according to the instructions; managers use mobile devices to monitor the pass rate (96.5% / 95.8%), energy consumption and carbon footprint data of the two bottle production lines in real time.
