Detailed implementation manners

[0013] By providing an environmental parameter control system for the processing of steel pipes for automotive parts, the present application solves the technical problems in the prior art that due to the lack of precise control of environmental parameters based on the analysis of phase state changes, the quality of pipe fittings is poor and the production efficiency is low. The technical goal of precise control of environmental parameters based on the analysis of phase state changes is achieved, and the technical effect of improving the quality of pipe fittings and the production efficiency is achieved.

[0014] Next, the technical solutions in the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described herein. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application. In addition, it should be noted that for the sake of description, only the parts related to the present application are shown in the drawings rather than all of them.

[0015] Embodiment, please refer to the attached Figure 1 , the present application provides an environmental parameter control system for the processing of steel pipes for automotive parts, which specifically includes: An environmental control element reading unit 11, configured to read the environmental control elements of the processing production line of steel pipes for automotive parts and read the environmental control records, where the environmental control elements include chemical environment and physical environment.

[0016] Specifically, the environmental control elements of the processing production line of steel pipes for automotive parts are read. The environmental control elements include chemical environment and physical environment. The chemical environment includes chemical components in the air, the content of corrosive substances, etc., while the physical environment includes temperature, humidity, dust, etc. The environmental control records are read, including the monitoring data and regulation measures of the environmental control elements in the past period of time.

[0017] A phase change constraint relation determination unit 12, configured to combine the environmental control elements and the environmental control records, perform phase state change analysis of pipe fitting processing, and determine the phase change constraint relation, where the phase state change includes plastic deformation and microstructural change.

[0018] Specifically, environmental control factors have a significant impact on the phase change of pipe fittings. To ensure the quality and performance of pipe fittings, an in-depth analysis of the impact is carried out. The phase change analysis involves the evaluation of plastic deformation and microstructural changes experienced by pipe fittings during the processing. First, the environmental control factors are combined with the corresponding environmental control records, including the actual measured values of parameters such as temperature, humidity, and chemical substance concentration, to more accurately analyze how environmental conditions affect the phase state of pipe fittings. Next, the phase change analysis of pipe fitting processing is carried out. Plastic deformation refers to the changes in the shape and size of pipe fittings during processing, such as bending, stretching, or compression. Microstructural changes involve the alteration of the internal structure of pipe fittings, such as grain size and distribution, and phase composition. By analyzing the phase change, the phase change constraint relationship is determined, that is, how environmental control factors affect the plastic deformation and microstructural changes of pipe fittings, so as to provide a basis for formulating reasonable processing parameters and environmental control strategies.

[0019] The adaptive adjustment module training unit 13 is used to construct an inverse recognition framework based on the phase change constraint relationship and supervise the training of the adaptive adjustment module.

[0020] Specifically, the phase change constraint relationship is the key to understanding how environmental control factors affect the phase change during pipe fitting processing. Based on the phase change constraint relationship, an inverse recognition framework is constructed to identify the phase change from the environmental control records and adjust the environmental control strategy. Next, in order to enable the inverse recognition framework to adaptively adjust the environmental control strategy, supervised training is carried out, and then the phase change is predicted based on the actual measured environmental parameters, and the control parameters are automatically adjusted to maintain the optimal environmental conditions.

[0021] The environmental gain requirement determination unit 14 is used to obtain the quality standard of the pre-processed pipe fittings, combine the main line processing and environmental assistance, decompose the quality standard, and determine the environmental gain requirement.

[0022] Specifically, in order to ensure that the quality of pipe fittings meets the predetermined standards, the quality standards of pre-processed pipe fittings are obtained, including requirements such as dimensional accuracy, surface finish, mechanical properties, and corrosion resistance of pipe fittings. Combining the main line processing process and environmental assistance conditions, the quality standard is analyzed. The main line processing process refers to the forming, cutting, welding, etc. steps that pipe fittings experience on the main processing equipment, while the environmental assistance conditions include environmental control factors such as temperature, humidity, and chemical substance concentration. Decomposing the quality standard is to determine the environmental factors that have a significant impact on the quality of pipe fittings during the main line processing process. Each quality standard item is analyzed in detail to identify various environmental factors that affect the standard. After determining the environmental factors that affect the quality standard, the environmental gain requirement is further determined. The environmental gain requirement refers to optimizing and adjusting the environmental conditions to meet or exceed the quality standard, including adjusting the temperature range, controlling the humidity level, reducing the concentration of harmful chemical substances, etc.

[0023] An environmental parameter strategy determination unit 15, configured to perform a reverse deduction based on the phase state in combination with the adaptive adjustment module for the environmental gain requirement, and determine an environmental parameter strategy for the entire processing cycle.

[0024] Specifically, in order to meet the environmental gain requirement, a reverse deduction based on the phase state is performed in combination with the adaptive adjustment module. Reverse deduction is a strategy formulation method that starts from the final goal and analyzes the conditions required to achieve the goal in reverse. To meet the quality standards of the pipe fittings, an environmental parameter strategy for the entire cycle is determined. Based on the quality standards of the pre-processed pipe fittings, the environmental gain requirement is clarified. The adaptive adjustment module is used to automatically adjust the control strategy according to the actually measured environmental parameters. During the reverse deduction process, the environmental parameters are analyzed and adjusted under different phase states to achieve the quality standards. The environmental parameter strategy for the entire processing cycle is determined through reverse deduction, guiding the whole process from raw material preparation to the completion of the final product, ensuring that the most suitable environmental conditions can be provided at each stage, thereby achieving the quality standards of the pipe fittings.

[0025] An environmental control unit 16, configured to perform environmental control for the processing of the pre-processed pipe fittings in response to the production line control system according to the environmental parameter strategy.

[0026] Specifically, the environmental parameter strategy is designed to ensure the quality and performance of the pipe fittings, that is, the environmental parameter strategy is formulated based on the quality standards of the pre-processed pipe fittings, the environmental gain requirement, and the phase state change analysis. The environmental parameter strategy includes specific requirements for environmental control elements such as temperature, humidity, and chemical substance concentration. The production line control system is a system responsible for monitoring and adjusting the processing process, and controls the operation of the processing equipment according to the preset programs and parameters. The environmental parameter strategy needs to be closely integrated with the production line control system to ensure that the environmental conditions during the processing process can be effectively controlled. When the production line control system is started, the environmental parameter strategy will take effect. According to the parameter ranges and conditions defined in the environmental parameter strategy, the processing environment is monitored in real time. If it is detected that the environmental parameters deviate from the range set by the strategy, adjustments are made to bring the environmental parameters back to the normal range.

[0027] The environmental parameter control system for the processing of automotive part steel pipes achieves the technical goal of precise control of environmental parameters based on phase state change analysis, and achieves the technical effect of improving the quality and production efficiency of pipe fittings.

[0028] Further, as Figure 2 shown, this application further includes: Traverse the environmental control records, conduct an analysis of the evolutionary trend of elements based on environmental control parameters and environmental control elements, and determine the first constraint relationship for measuring relative influence, where the environmental control parameters are determined based on the production line configuration equipment; conduct an analysis of the evolutionary trend of phase change based on environmental control elements and phase states, and determine the second constraint relationship; based on the hierarchical mapping relationship, fit the first constraint relationship and the second constraint relationship to determine the phase change constraint relationship, where the hierarchical mapping relationship is a many-to-one relationship based on environmental control parameters - environmental control elements - phase states.

[0029] Specifically, conduct a comprehensive inspection and analysis of the environmental control records, review each data point in the records, and conduct an analysis of the evolutionary trend of elements based on environmental control parameters and environmental control elements. The environmental control parameters are determined according to the production line configuration equipment, including the operating speed of the equipment, temperature settings, humidity control, etc. By analyzing the relationship between environmental control parameters and environmental control elements, determine the environmental control parameters that have a greater impact on the environment, and thus establish the first constraint relationship.

[0030] At the same time, conduct an analysis of the evolutionary trend of phase change based on environmental control elements and phase states. The phase state refers to the state of the material, such as solid, liquid or gas and the transition state, and is used to obtain how the phase state changes under different environmental conditions and how the change affects the process of processing steel pipes for automotive parts, and determine the second constraint relationship.

[0031] Finally, use the hierarchical mapping relationship to combine the first constraint relationship and the second constraint relationship. The hierarchical mapping relationship is a many-to-one relationship based on environmental control parameters, environmental control elements and phase states, and determine the phase change constraint relationship. The phase change constraint relationship is a comprehensive constraint relationship obtained according to the interaction between environmental control parameters, environmental control elements and phase states.

[0032] Predict and control the impact of environmental changes on the processing of steel pipes for automotive parts through fitting, so as to improve the processing quality.

[0033] Furthermore, this application also includes: Traverse the hierarchical mapping relationship, conduct an analysis of the mutual influence of the same mapping layer, and determine the collaborative influence relationship; add the collaborative influence relationship into the phase change constraint relationship.

[0034] Specifically, traverse the hierarchical mapping relationship, analyze the mutual influence between different elements within the same mapping layer, identify how each environmental control element interacts and influences at the same level, and determine the collaborative influence relationship. The collaborative influence relationship refers to the influence of the interaction between different environmental control elements within the same mapping layer on the environment of the production line for processing steel pipes for automotive parts, including combinations of positive correlation, negative correlation or independent factors.

[0035] Then, after determining the co-influence relationship, integrate the co-influence relationship into the phase change constraint relationship. The phase change constraint relationship already takes into account the many-to-one relationship between environmental control parameters, environmental control elements, and phase states. Now, by adding the co-influence relationship, a more comprehensive understanding of the complex interactions between environmental control elements can be achieved.

[0036] Through integration, the phase change constraint relationship becomes more precise, including not only the direct effects of environmental control parameters and environmental control elements but also the co-effects between elements. This helps to formulate more effective environmental control strategies, ensure the environmental stability of the automotive parts steel pipe processing line, and thus improve the quality and consistency of products.

[0037] Furthermore, this application also includes: Based on the hierarchical mapping relationship, determine multiple sub-frames, where each sub-frame corresponds one-to-one to a phase state; based on the phase change constraint relationship, initialize the multiple sub-frames and integrate them to determine an integrated frame; construct a phase state decision tree, and establish a mapping association between the phase state decision tree and the integrated frame to determine the inverse recognition frame; integrate the environmental control records as sample data and perform supervised training on the inverse recognition frame to generate the adaptive adjustment module.

[0038] Specifically, determine multiple sub-frames based on the hierarchical mapping relationship. Each sub-frame corresponds one-to-one to a different phase state, and each sub-frame represents a specific phase state, such as solid, liquid, or gas, as well as possible phase change processes.

[0039] Next, use the phase change constraint relationship to initialize the sub-frames and integrate the sub-frames into a larger frame, namely the integrated frame. The integrated frame takes into account the mutual relationships and influences between different phase states, providing a comprehensive perspective to understand and control the impact of environmental parameters on the automotive parts steel pipe processing.

[0040] Then, to further optimize the decision-making process, establish a phase state decision tree. The phase state decision tree is a decision support tool that provides corresponding decision paths according to different environmental conditions and phase states. Establish a mapping association between the phase state decision tree and the integrated frame to ensure that the decision tree can accurately reflect the environmental control requirements under different phase states.

[0041] Next, after determining the mapping association, determine the inverse recognition frame. The inverse recognition frame can identify phase state changes from the environmental control records and adjust the environmental control strategy. The inverse recognition frame is obtained through reverse engineering of the integrated frame and can predict and adjust the phase state based on actual environmental data.

[0042] Finally, integrate the environmental control records into sample data, use historical data to train the model, and conduct supervised training on the inverse recognition framework to adaptively adjust the control strategy according to environmental changes. Through training, an adaptive adjustment module is generated, which can monitor environmental changes in real time and automatically adjust control parameters.

[0043] By generating an adaptive adjustment module, the best environmental conditions can be maintained, ensuring the processing quality and performance of steel pipes for automotive parts.

[0044] Furthermore, this application also includes: Based on the environmental gain requirements, determine the phase state changes during the entire processing cycle; traverse the phase state changes, combine with the adaptive adjustment module, traverse each change node, match based on the phase state decision tree, match the target sub-framework based on the mapping relationship, and determine multiple node strategies; serially integrate the multiple node strategies in a positive sequence to determine the environmental parameter strategy.

[0045] Specifically, to meet the environmental gain requirements, determine the phase state changes during the entire processing cycle. Phase state changes refer to how the phase state (such as solid, liquid, or gas) changes over time and processing conditions at different stages of pipe fitting processing. Determining phase state changes is crucial for formulating appropriate environmental control strategies to determine how to adjust environmental parameters to optimize the processing process.

[0046] Next, sequentially access the phase state changes, and combine with the adaptive adjustment module to automatically adjust the control strategy according to the actually measured environmental parameters. During the sequential access to each change node, check each change node, which is the key point of phase state change. At each change node, use the phase state decision tree for matching. The phase state decision tree is a decision support tool that provides corresponding decision paths according to different environmental conditions and phase states. By matching the decision tree, determine the measures to be taken at a specific change node.

[0047] Then, match the target sub-framework based on the mapping relationship. The sub-framework is the framework corresponding to a specific phase state and represents different environmental control requirements. By matching the target sub-framework, ensure that appropriate environmental control strategies are applied at specific change nodes.

[0048] Then, after determining the strategy for each node, serially integrate the strategies in a positive sequence. Serial integration in a positive sequence means organizing the strategies of all nodes in the order of the processing process to form a coherent environmental parameter strategy, guiding the environmental control of the entire processing process and ensuring that the quality requirements of the pipe fittings are met at each stage.

[0049] By ensuring that environmental parameters can be appropriately adjusted and controlled at each stage of the steel pipe processing for automotive parts, the processing efficiency and product quality can be improved.

[0050] Furthermore, the present application further includes: Traverse the multiple node strategies, determine the over-limit node parameters based on the instantaneous shock threshold, where the instantaneous shock threshold corresponds one-to-one with the environmental control parameters, and the over-limit nodes are neighboring node pairs with a parameter amplitude adjustment greater than the instantaneous shock threshold; perform multi-step conversion based on the node amplitude adjustment on the over-limit node parameters, and integrate to determine the environmental parameter strategy.

[0051] Specifically, in order to ensure that the control strategy of the environmental parameters can adapt to the instantaneous changes during the processing, traverse the multiple node strategies to identify parameter changes that exceed the normal range within a short period of time, that is, over-limit node parameters. The instantaneous shock threshold is set in the environmental control parameters and is used to determine whether the parameter change exceeds the normal range. Each environmental control parameter has a corresponding instantaneous shock threshold. When the change amplitude of the parameter is greater than the instantaneous shock threshold, it is considered that an over-limit node appears. An over-limit node refers to a node in the neighboring node pair with a parameter amplitude adjustment greater than the instantaneous shock threshold. If the single-step amplitude adjustment is large, it will affect the control energy efficiency and may even affect the build life.

[0052] Then, once the over-limit node parameters are identified, perform multi-step conversion on the over-limit node parameters. Multi-step conversion is an adjustment method that adjusts the environmental control parameters according to the amplitude adjustment of the node (i.e., the parameter change amplitude). After performing multi-step conversion, integrate the strategies of all nodes, including the converted over-limit node parameters, to determine the final environmental parameter strategy, which will guide the environmental control of the entire processing process to ensure that suitable environmental conditions can be maintained at each stage, thereby improving the quality and consistency of pipe fitting processing.

[0053] By gradually adjusting the parameters, excessive instantaneous shocks during the processing can be avoided, thereby maintaining the stability of the processing process.

[0054] Furthermore, the present application further includes: Determine the phase degree of freedom based on the environmental gain requirement, where the phase degree of freedom is determined based on the demand tolerance interval; derive the control degree of freedom based on the phase degree of freedom; determine the feedback constraint conditions based on the phase degree of freedom and the control degree of freedom.

[0055] Specifically, to meet the environmental gain requirement, determine the phase degree of freedom. The phase degree of freedom refers to the range within which the phase (such as solid, liquid, or gas) can change during the processing, and the phase degree of freedom is determined based on the demand tolerance interval. The demand tolerance interval refers to the interval within which the phase parameters can fluctuate without affecting the final quality of the pipe fitting.

[0056] Then, after determining the phase state degrees of freedom, the control degrees of freedom are derived. The control degrees of freedom refer to the range of environmental control parameters that can be adjusted during the actual processing. The control degrees of freedom need to be broad enough to achieve the desired phase state changes within the phase state degrees of freedom, but not too broad to avoid unnecessary resource waste or negative impacts on the environment.

[0057] Finally, based on the phase state degrees of freedom and the control degrees of freedom, the feedback constraint conditions are determined. The feedback constraint conditions refer to the rules for adjusting the processing based on the real-time data of the phase state and environmental control parameters during the actual processing. The feedback constraint conditions ensure that the processing can proceed stably within the range of the phase state degrees of freedom and the control degrees of freedom, and can also quickly adjust the environmental control parameters when necessary to cope with emergencies or unexpected phase state changes.

[0058] By ensuring that during the processing of steel pipes for automotive parts, the environmental control strategy can flexibly respond to changes in the phase state and maintain within the predetermined quality standard range, the stability of the processing and the quality of the pipe fittings are improved.

[0059] Furthermore, this application also includes: Based on the feedback constraint conditions, a digital feedback device is configured, where the digital feedback device is communicatively connected to the adaptive adjustment module; the processing control monitoring is synchronously performed and transmitted back to the digital feedback device for deviation adjustment determination to obtain a determination result; the determination result is identified, and if there is a feedback adjustment instruction, a feedback decision on environmental control is made in combination with the adaptive adjustment module; where the deviation adjustment determination includes: if the control deviation is less than or equal to the degrees of freedom, the control deviation is set to zero; if the control deviation is greater than the degrees of freedom, a feedback adjustment instruction is generated.

[0060] Specifically, to ensure that the environmental control can respond in real time to changes during the processing, a digital feedback device needs to be configured based on the feedback constraint conditions. The digital feedback device is a device for monitoring and controlling the system, which can receive the data of the processing control in real time and process it. The digital feedback device is communicatively connected to the adaptive adjustment module to share information and instructions. The adaptive adjustment module is generated based on supervised training and can automatically adjust the environmental control strategy according to the real-time data. During the processing, the digital feedback device synchronously performs the processing control monitoring, collects the data during the processing in real time, such as temperature, humidity, chemical substance concentration, etc. The collected data is transmitted back to the digital feedback device for deviation adjustment determination. The deviation adjustment determination refers to comparing the difference between the actually measured environmental parameters and the target values set according to the environmental parameter strategy.

[0061] Then, if the control deviation is less than or equal to the degree of freedom, that is, the parameter fluctuation is within the acceptable range, the digital feedback device will set the control deviation to zero, considering the current environmental control to be effective and no adjustment is required. If the control deviation is greater than the degree of freedom, that is, the parameter fluctuation exceeds the acceptable range, the digital feedback device will generate a feedback adjustment instruction, including adjustment measures, to bring the environmental parameters back to the normal range. After receiving the feedback adjustment instruction, the adaptive adjustment module will make a feedback decision on environmental control in combination with the feedback adjustment instruction, including adjusting environmental control elements such as temperature settings, humidity control, and chemical substance concentration, to achieve precise control of the processing environment.

[0062] The digital feedback device and the adaptive adjustment module together form a closed-loop control system, which can monitor and adjust the processing environment in real time to ensure that the pipe fitting processing process meets the predetermined quality standards.

[0063] In summary, the environmental parameter control system for automotive parts steel pipe processing provided by this application has the following technical effects: Through the environmental control element reading unit, which is used to read the environmental control elements of the processing line of automotive parts steel pipes and read the environmental control records, the environmental control elements include chemical environment and physical environment; the phase change constraint relationship determination unit, which is used to combine the environmental control elements and the environmental control records to conduct phase change analysis of pipe fitting processing and determine the phase change constraint relationship, where the phase change includes plastic deformation and microstructure change; the adaptive adjustment module training unit, which is used to construct an inverse recognition framework based on the phase change constraint relationship and supervise and train the adaptive adjustment module; the environmental gain requirement determination unit, which is used to obtain the quality standard of the pre-processed pipe fitting, combine the main line processing and environmental assistance, decompose the quality standard, and determine the environmental gain requirement; the environmental parameter strategy determination unit, which is used to perform reverse deduction based on the phase state for the environmental gain requirement in combination with the adaptive adjustment module to determine the environmental parameter strategy for the entire processing cycle; the environmental control unit, which is used to respond to the production line control system for the environmental parameter strategy and conduct environmental control for the processing of the pre-processed pipe fitting, achieving the technical goal of precise control of environmental parameters based on phase change analysis and achieving the technical effect of improving the quality and production efficiency of pipe fittings.
