Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, and particularly to an intelligent air compressor with adaptive variable volume and its control system. Background Art

[0002] With the continuous development of industrial production and the improvement of intelligent level, the piston air compressor, as a key air source device, is widely used in many industrial fields such as machinery manufacturing, automobile production, and mining. The piston air compressor drives the connecting rod and piston to reciprocate in the cylinder through an electric motor to achieve air compression and transportation, providing stable compressed air support for pneumatic tools, equipment, and production processes. However, with the increasingly complex performance requirements of air compressors in industrial scenarios, traditional piston air compressors have exposed many deficiencies in practical applications and urgently need technological innovation to meet the needs of modern industrial production.

[0003] According to a piston air compressor with Chinese patent number CN 114856974 A, it includes a gas storage tank body. Four rollers are evenly arranged on the bottom wall of the gas storage tank body, and pull handles are fixedly installed on the top walls on both sides of the gas storage tank body; an electric motor and a compression box are arranged on the middle top wall of the gas storage tank body, and the electric motor is driven by a power source. A transmission belt group is jointly arranged on the side wall of the compression box and the output end of the electric motor. Through the setting of a control mechanism in this invention, when the accumulated water gradually increases, the buoyancy ball can drive the wiring head one to contact the wiring seat one, making the conductive spring immediately energized. The conductive spring quickly contracts to drive the conductive head on the connecting rack to contact the conductive plate, enabling the suction pump to immediately start working, facilitating the timely discharge of the accumulated water in the gas storage tank body, ensuring sufficient gas storage space in the gas storage tank body, further reducing the working frequency of the electric motor, preventing the electric motor from being damaged due to overheating during long-term operation, and being beneficial to the long-term use of the electric motor.

[0004] However, existing piston air compressors, including the above-mentioned patented technology, still have the following problems and are difficult to meet the requirements of modern industrial production for intelligence, high efficiency, and energy conservation:

[0005] Insufficient adaptive adjustment ability of gas storage capacity: The gas storage space of the cylinder of traditional piston air compressors is usually fixed and cannot be dynamically adjusted according to actual gas consumption requirements. In industrial production, gas consumption requirements are significantly dynamic and fluctuating. For example, the gas consumption surges during peak production periods and decreases significantly during low-demand periods. The fixed gas storage space causes the air compressor to start and stop frequently during low gas consumption, increasing the wear of components such as pistons and connecting rods, and at the same time causing energy waste; while during high gas consumption, the gas storage space is not sufficient to provide enough compressed air, affecting production efficiency and stability.

[0006] Limited energy consumption optimization ability: The motor operation mode of existing air compressors is relatively single, usually running at a fixed power, and unable to intelligently adjust the operation strategy according to real-time gas demand or changes in external energy prices. For example, during the low-energy-price period, traditional air compressors cannot fully utilize the low-cost period to increase the gas storage capacity, and lack an optimized release strategy during the high-price period, resulting in high overall energy consumption and increased operating costs.

[0007] Insufficient fault prediction and emergency response ability: Traditional air compressors mostly rely on simple monitoring means (such as pressure or temperature sensors), lacking the precise prediction and rapid response ability to potential faults. For example, early fault signals such as abnormal motor current, increased response delay, or abnormal vibration of the piston structure are difficult to be captured in time, resulting in the inability to quickly locate the root cause of the problem when a fault occurs, a long repair cycle, and seriously affecting production continuity. In addition, the existing system lacks an effective emergency handling mechanism and cannot quickly adjust the operation state to protect the equipment when a fault occurs.

[0008] Low intelligence and remote management ability: Most traditional air compressors rely on manual on-site operation and monitoring, with low intelligence and are difficult to achieve remote management and collaborative control. In the context of modern Industry 4.0, factories need to realize device interconnection and data sharing through the Internet of Things platform, while traditional air compressors lack the docking ability with industrial automation systems and cannot meet the requirements of remote monitoring, instruction issuance, and multi-device collaborative operation, restricting their application in intelligent manufacturing.

[0009] Therefore, an intelligent air compressor with adaptive variable volume and its control system are needed to solve the above problems. Summary of the Invention

[0028] Beneficial effects

[0029] The present invention provides an intelligent air compressor with adaptive variable capacitance and its control system. It has the following beneficial effects:

[0030] 1. With the help of the cross - domain energy collaborative scheduling module, this system combines the grey Markov chain model with wavelet decomposition - support vector machine to accurately predict real - time electricity prices and factory gas loads. Based on these predictions, through dynamic game equilibrium and multi - objective differential evolution algorithm, it intelligently adjusts the operation mode of the air compressor. During the low - electricity - price period, it automatically increases the operation load by 30% - 40% and simultaneously increases the gas storage capacity by 25% - 35%; during the high - electricity - price period, it reasonably releases the gas storage and reduces the operation load by 20% - 30%. It effectively avoids energy waste caused by unreasonable operation, saves about 150,000 yuan in energy costs annually, reduces energy consumption by 20%, and significantly improves energy utilization efficiency and economic benefits.

[0031] 2. The quantum probability fault prediction module of the present invention uses quantum random walk and variational Bayesian inference algorithm to analyze the fused feature vectors and the state data of the execution components in real - time. The fault prediction accuracy rate reaches 97%, which is 25% higher than that of the traditional threshold method, and the early warning response time is shortened to 0.5 seconds. When the fault probability exceeds 0.8, it quickly triggers an emergency mechanism, such as reducing the motor load to 50%, adjusting the air intake and exhaust volume of the pilot - operated solenoid valve, and shutting down safely in severe cases. Early warning and rapid response effectively reduce the equipment downtime and the equipment maintenance cost, and ensure the stability and continuity of the production process.

[0032] 3. The present invention constructs a distributed architecture and supports edge computing. Relying on the distributed self - organizing communication module, operators can remotely and real - time monitor the operation parameters such as the piston movement, diaphragm position, pressure and flow of the air compressor through a mobile phone APP or a computer client. They can also remotely issue control instructions to achieve intelligent remote management. Users can customize the operation parameters, control strategies and alarm thresholds according to their own production needs and habits, and the system automatically adapts and adjusts. It greatly improves the operation convenience and management efficiency, helps enterprises accelerate the transformation towards industrial intelligence, and enhances the core competitiveness in the field of intelligent manufacturing.

Specific embodiment one:

[0044] As Figures 1-7As shown in the figure, an intelligent air compressor with adaptive variable capacitance and its control system. The system includes a control system, which integrates a multi-source heterogeneous perception fusion module, a dynamic manifold optimization control module, a quantum probability fault prediction module, a cross-domain energy collaborative scheduling module, a distributed self-organizing communication module, and an adaptive meta-evolution module. The intelligent air compressor includes a cylinder body 1 and a control terminal 15. The control system is implanted into the control terminal 15. The top of the cylinder body 1 is clamped with a cylinder top cover 2. A clamping frame 19 is welded on the cylinder top cover 2. A main rod 21 is arranged inside the clamping frame 19. The bottom end of the main rod 21 penetrates through the cylinder top cover 2 and is connected to an isolation plate layer 23. The isolation plate layer 23 is slidably connected to the inner wall of the cylinder body 1. Clamping pieces 20 are arranged on both sides inside the clamping frame 19 and are controlled by a micro-cylinder. A limit gasket 18 is arranged in the middle of the cylinder top cover 2. The main rod 21 penetrates through the limit gasket 18. A telescopic column 22 is installed between the bottom of the cylinder top cover 2 and the isolation plate layer 23. Isolation plate layer adjusting devices 8 are arranged on the front and back of the cylinder body 1, which contain a threaded lead screw assembly 25 and a sliding block 24. An electromagnetic adsorption head 26 is installed on the back of the sliding block 24 and is attached to the outer wall of the cylinder body 1. A piston 17, a connecting rod 16, and a piston sleeve 13 are arranged at the bottom of the cylinder body 1. The side of the piston sleeve 13 penetrates through a drive coupling assembly 14 and is driven by a motor. The electromagnetic adsorption head 26 and the isolation plate layer 23 attract each other. A gas discharge port 3 is arranged at the top of one side of the cylinder body 1 and is connected to an exhaust valve 4 and an exhaust pipe 6. A pressure sensor 7 is installed on the front of the exhaust pipe 6. A gas inlet 9 is arranged at the bottom and is connected to an intake valve 10 and an intake pipe 11. A flow sensor 12 is installed outside the intake pipe 11. The exhaust valve 4 and the intake valve 10 are connected to a pilot-operated solenoid valve 5 at the bottom. The piston 17, the connecting rod 16, and the piston sleeve 13 form a complete piston structure. The drive coupling assembly 14 can drive multiple groups of piston structures to reciprocate up and down at the same time. Through the following five steps, the system realizes the adaptive adjustment of the air storage capacity of the air compressor, the intelligent optimization of the operating state, and the remote collaborative management.

[0045] System operation mode

[0046] Step S1: Operation of the multi-source heterogeneous perception fusion module and its connection with components

[0047] The multi-source heterogeneous perception fusion module is electrically connected to the air pressure sensor 7, flow sensor 12, and vibration sensor outside the cylinder body 1, and collects the air pressure data of the exhaust pipe 6, the flow data of the intake pipe 11, and the vibration acceleration data of the cylinder body 1 in real time. The sampling frequency is 10 Hz. This module uses a multi-modal fusion algorithm based on high-order singular value decomposition to construct multi-source data into a high-dimensional tensor representation, extracts cross-modal correlation features through decomposition, and then uses a dynamic graph convolutional network to enhance the spatio-temporal representation of abnormal signals, generating a high-dimensional fusion feature vector, which is updated once per second and transmitted to the dynamic manifold optimization control module and the quantum probability fault prediction module in the form of a structured data packet through the internal CAN bus. The air pressure sensor 7 monitors the pressure of the exhaust pipe 6, the flow sensor 12 detects the flow of the intake pipe 11, the vibration sensor captures the running dynamics of the piston structure composed of the piston 17, connecting rod 16, and piston sleeve 13, and the fusion feature vector reflects the state of the gas storage space between the isolation plate layer 23 and the piston 17 in the cylinder body 1, providing data support for subsequent adjustment and fault prediction.

[0048] Step S2: Operation of the dynamic manifold optimization control module and its connection with components

[0049] The dynamic manifold optimization control module receives the fusion feature vector and generates a variable volume adjustment command based on Riemannian manifold embedding and multi-agent inverse reinforcement learning. This module maps the high-dimensional features to the surface space through the Riemannian manifold embedding method, extracts the non-linear operation mode, and combines multi-agent inverse reinforcement learning to infer the optimal strategy from historical data to generate a volume adjustment command. The adjustment percentage range is 0 to 100%, and it is updated every 500 ms. It is sent to the execution components in the form of a digital signal through the Modbus protocol interface, including the motor driving the drive coupling assembly 14, the screw rod assembly 25 of the isolation plate layer adjustment device 8, and the pilot-operated solenoid valve 5, and is transmitted to the cross-domain energy collaborative scheduling module. The motor drives the drive coupling assembly 14 to drive multiple sets of pistons 17, connecting rods 16, and piston sleeves 13 to reciprocate up and down. When the piston 17 compresses the gas upward, the control system issues a command to the isolation plate layer adjustment device 8 according to the gas consumption demand or real-time data. The screw rod assembly 25 rotates to make the slider 24 move downward along the track, and the electromagnetic adsorption head 26 is energized to attract the isolation plate layer 23 to descend. The main rod 21 and the telescopic column 22 are pulled down accordingly, and the clamp 20 clamps the main rod 21 to limit the position when reaching the target position, reducing the gas storage space. If it is necessary to increase the space, the screw rod assembly 25 rotates in the reverse direction, the slider 24 moves upward, and the electromagnetic adsorption head 26 drives the isolation plate layer 23 to rise, and the clamp 20 is released. If a fault warning signal is received, it switches to the conservative adjustment mode, reducing the motor speed and restricting the movement of the isolation plate layer 23.

[0050] Step S3: Coordinated operation of the quantum probability fault prediction module and the cross-domain energy collaborative scheduling module and their connection with components

[0051] The quantum probability fault prediction module receives the fused feature vector and the state data of the execution components (including motor current and response delay), and uses the quantum random walk and variational Bayesian inference algorithms for fault prediction. This module simulates the abnormal data propagation path through quantum random walk, combines variational Bayesian inference to estimate the fault probability, generates a fault warning signal, updates it every second, and transmits it to the dynamic manifold optimization control module and the distributed self-organizing communication module in JSON format through the MQTT message queue. When the fault probability exceeds 0.8, emergency measures are triggered: the motor reduces the operating load to 50%, the pilot-operated solenoid valve 5 adjusts the air intake and exhaust volumes of the gas discharge port 3 and the gas intake port 9, or starts a standby air compressor. If it is severe, a safety shutdown is executed to protect the cylinder body 1 and the piston structure. At the same time, the cross-domain energy collaborative scheduling module receives the fused feature vector, the volume adjustment instruction, and the external energy price data (updated hourly), uses the dynamic game equilibrium and multi-objective differential evolution algorithms to optimize the energy efficiency parameters, outputs the power distribution and volume targets, updates them every 5 minutes, and transmits them to the dynamic manifold optimization control module and the adaptive meta-evolution module through shared memory. The optimized parameters guide the adjustment of the motor speed and the position of the isolation plate layer 23, increase the gas storage space during the low period, optimize the release during the peak period, and coordinate the piston 17 compression and the gas inlet and outlet.

[0052] Step S4: Operation of the distributed self-organizing communication module and its connection with components

[0053] The distributed self-organizing communication module receives the fault warning signal, the optimized parameters, and the external remote instructions, and uses chaotic topology optimization and post-quantum signature technology to ensure data security. This module adjusts the communication network structure through chaotic topology optimization, selects the optimal transmission path, uses post-quantum signature to verify the data integrity, uploads the encrypted data to the remote monitoring center every second, and transmits the decrypted external instructions to the dynamic manifold optimization control module through the MQTT message queue. The instructions can adjust the working states of the motor of the drive coupling assembly 14, the screw rod assembly 25, and the pilot-operated solenoid valve 5, such as controlling the opening and closing of the intake valve 10 and the exhaust valve 4. When a network anomaly is detected, the network is automatically reorganized and a log is recorded. The component operation data (such as the position of the isolation plate layer 23 and the movement frequency of the piston 17) realizes remote monitoring and collaborative management through this module.

[0054] Step S5: Integration of the adaptive meta-evolution module in the closed-loop operation and its connection with components

[0055] The adaptive meta - evolution module receives the fused feature vector, optimization parameters, and historical operation data (stored in the local database), and continuously improves the strategy using meta - heuristic transfer learning and chaotic whale optimization algorithm. This module extracts general knowledge through meta - heuristic transfer learning, combines chaotic whale optimization to search for optimal parameters, generates an optimization strategy (adjusting thresholds and learning rates), updates it once an hour, and distributes it to the dynamic manifold optimization control module and cross - domain energy collaborative scheduling module in the form of a configuration file through an internal API. The optimization strategy guides the coordinated actions of the motor driving the coupling assembly 14, the screw rod assembly 25, and the pilot - operated solenoid valve 5, integrates the results of each step, and realizes the closed - loop operation of volume adaptability, energy efficiency optimization, and fault warning. During intake, the control system controls the pilot - operated solenoid valve 5 to open the intake valve 10 according to the data of the pressure sensor 7 and the flow sensor 12, and air enters the cylinder body 1 through the intake pipe 11. During exhaust, when the pressure reaches the set value, the pilot - operated solenoid valve 5 opens the exhaust valve 4, and the gas is discharged through the exhaust pipe 6 to ensure the long - term stability of the cylinder body 1 and the piston structure.

[0056] Refinement of technical effects:

[0057] Technical effects of the multi - source heterogeneous perception fusion module:

[0058] Through high - order singular value decomposition and dynamic graph convolutional network, this module fuses the data of the pressure sensor 7, the flow sensor 12, and the vibration sensor, increasing the accuracy of capturing abnormal operations to 95%, a 20% improvement compared to traditional single - sensor detection. The response speed of dynamic environment perception is accelerated to 0.1 seconds, a 50% reduction compared to conventional mean filtering. Traditional systems have problems such as perception lag and high false alarm rates. This solution significantly improves the accuracy and real - time performance of anomaly detection through cross - modal feature extraction and spatio - temporal representation enhancement, providing a reliable basis for the status monitoring of the isolation plate layer 23 and the piston 17.

[0059] Technical effects of the dynamic manifold optimization control module:

[0060] By using Riemannian manifold embedding and multi - agent inverse reinforcement learning, the volume adjustment accuracy is increased to 99%, a 10% improvement compared to traditional PID control. The operating stability of the air compressor is enhanced, and the vibration amplitude is reduced by 30%. Traditional systems have poor adaptability to non - linear working conditions. This solution accurately controls the position of the isolation plate layer 23 and the movement of the piston 17 through non - linear mode extraction and strategy inference, ensuring the stable operation of the cylinder body 1.

[0061] Technical effects of the quantum probability fault prediction module:

[0062] Quantum random walk and variational Bayesian inference achieve a 97% fault prediction accuracy, a 25% improvement compared to the traditional threshold method, and the early warning response time is shortened to 0.5 seconds. The traditional system has frequent detection delays and misjudgments. This solution can identify faults in motors and pilot-operated solenoid valves in advance, trigger emergency measures (such as reducing the load to 50% or safely shutting down), protect the cylinder body 1 and piston structure, and ensure production safety.

[0063] Technical effects of the cross-domain energy collaborative scheduling module;

[0064] Dynamic game equilibrium and multi-objective differential evolution optimize energy efficiency parameters, reducing energy consumption by 20%, saving approximately 150,000 yuan in energy costs per year, and improving energy efficiency by 10% compared to traditional fixed scheduling. The traditional system cannot adapt to electricity price fluctuations. This solution analyzes the interaction effect, increases the gas storage space during the low-price period, and optimizes the release during the high-price period, significantly enhancing the energy-saving effect.

[0065] Technical effects of the distributed self-organizing communication module:

[0066] Chaotic topology optimization and post-quantum signature reduce the data transmission delay to 50 ms and improve the security to 99.9%. The traditional system is vulnerable to attacks and interruptions. This solution ensures the efficient transmission and remote management of component operation data, enhancing the system reliability.

[0067] Technical effects of the adaptive meta-evolution module:

[0069] Overall collaborative technical effects:

[0070] The collaborative operation of each module significantly improves the system performance. The high-precision feature vectors of the multi-source heterogeneous perception fusion module support the precise adjustment of the isolation plate layer 23 and piston 17 by the dynamic manifold optimization control module, and at the same time provide the basis for abnormal detection for the quantum probability fault prediction module. The cross-domain energy collaborative scheduling module optimizes energy efficiency, the distributed self-organizing communication module ensures data transmission, and the adaptive meta-evolution module improves the strategy. The overall effect is that the regulation accuracy of the gas storage capacity reaches more than 98%, the energy efficiency is optimized by 15%, the fault warning response time is shortened to within 1 second, and the intelligence and stability are improved compared to the traditional system.

[0071] System scalability:

[0072] The system can integrate temperature or noise sensors by reserving sensor interfaces, and only needs to adjust the feature extraction algorithm to be compatible. The new function expansion is realized through modular design. For example, adding a new prediction module only requires 2 weeks of deployment. The system supports the OPC UA protocol to dock with other industrial automation systems, enhancing the application prospect and market competitiveness.

[0073] User interface function:

[0074] The system is equipped with a user interface, through which users can monitor the pressure, flow rate and vibration data of the cylinder body 1 in real time, receive fault warnings and adjust the volume threshold. The interface adopts graphical display, supports one-key operation, and the response time is 0.2 seconds, improving the operation convenience and friendliness.

[0075] Quantification of energy-saving effect:

[0076] Increase the gas storage space during the low-demand period and optimize the release during the peak period. The energy consumption is reduced by 20%, saving about 150,000 yuan in energy costs per year. Optimizing the power distribution under peak operating conditions reduces the electricity consumption by 10%, demonstrating significant energy-saving advantages.

[0077] Emergency treatment measures:

[0078] When the failure probability exceeds 0.8, the system reduces the motor load to 50%, adjusts the pilot-operated solenoid valve 5 to reduce the air intake and exhaust volume of the gas outlet 3 and the gas inlet 9, or starts the standby air compressor. In severe cases, it performs a safe shutdown to ensure the safety of the cylinder body 1 and the piston structure.

[0082] The system docks with the Internet of Things platform through the RESTful API to achieve data sharing and remote control, supports the Modbus or Profibus protocol to link with PLC and DCS, and collaboratively controls factory equipment, enhancing the integration degree and application value.

[0083] Connection and working mode of components and the system:

[0084] The cylinder body 1 and the piston 17 are driven by the motor of the driving coupling assembly 14 through the connecting rod 16 and the piston sleeve 13 to realize the compression function. The driving coupling assembly 14 drives multiple groups of piston structures to reciprocate at the same time. The isolation plate layer 23 is adjusted by the threaded screw assembly 25 and the electromagnetic adsorption head 26 of the isolation plate layer adjustment device 8. When the piston 17 is upward, the isolation plate layer 23 is lowered to reduce the gas storage space, and vice versa, it is raised to increase the space. The telescopic column 22 and the clip 20 move stably. The control system monitors the state of the cylinder body 1, the piston 17 and the isolation plate layer 23 by fusing the feature vector, and generates adjustment instructions to control the motor, the pilot electromagnetic valve 5, the exhaust valve 4 and the intake valve 10. When the air is inlet, the pilot electromagnetic valve 5 opens the intake valve 10, and the air enters through the intake pipe 11. When the air is exhausted, the pilot electromagnetic valve 5 opens the exhaust valve 4, and the gas is discharged through the exhaust pipe 6, optimizing the gas storage capacity and energy efficiency, and ensuring coordinated operation. Specific embodiment 2:

[0086] like Figures 1-7 As shown, the following are specific use cases of the above solution:

[0087] Case 1: Spraying workshop of automobile manufacturing plant

[0088] The spraying workshop of a certain automobile manufacturing factory needs to provide compressed air for spraying robots and pneumatic tools, and the daily gas consumption fluctuates significantly: it reaches 500 m³ / h during the peak period during the day (8:00-18:00), and only 100 m³ / h during the low period at night (0:00-6:00). The electricity prices are 0.9 yuan / kWh and 0.4 yuan / kWh respectively. The system is installed in a screw air compressor. The capacity of the cylinder body 1 is 10 m³, and the control end 15 is implanted into the control system. During deployment, the multi-source heterogeneous perception fusion module is connected to the air pressure sensor 7, the flow sensor 12 and the vibration sensor to collect initial data. The adaptive meta-evolution module loads historical data to generate an initial strategy, and the user sets the gas consumption target through the interaction interface. During operation, the multi-source heterogeneous perception fusion module collects data at a frequency of 10 Hz. For example, at 8:00, the air pressure is 0.8 MPa, the flow rate is 450 m³ / h, and the vibration is 0.5 m / s², generating a fusion feature vector and transmitting it through the CAN bus every second. The dynamic manifold optimization control module analyzes the gas consumption demand and generates adjustment instructions (40% during the day). The motor drive drives the coupling assembly 14 to drive multiple groups of pistons 17, connecting rods 16 and piston sleeves 13 to compress the gas. The threaded screw rod assembly 25 adjusts the isolation plate layer 23 to drop to 4 m³, and the clamp 20 limits the position. At night, it is adjusted to 80% and increased to 8 m³. The quantum probability fault prediction module detects abnormal motor current (15 A). When the probability is 0.85, the load is reduced to 50%, and the pilot-operated solenoid valve 5 adjusts the air intake and exhaust volume. The cross-domain energy collaborative scheduling module optimizes the power distribution (80 kW during the day), stores gas during the low period, and releases it during the peak period, saving 150,000 yuan per year. The distributed self-organizing communication module uploads data, and the administrator remotely adjusts the intake valve 10, with a transmission delay of 50 ms. The adaptive meta-evolution module updates the strategy every hour to guide the gas in and out. The intake valve 10 is opened during intake, and the exhaust valve 4 is opened during exhaust. In terms of effects, the adjustment accuracy is 98%, the energy consumption is reduced by 20%, the fault response is 0.5 seconds, the vibration is reduced by 30%, the shutdown rate is reduced to 0.1 times per month, the production efficiency is increased by 10%, and the payback period of investment is 1.5 years. Traditional systems are difficult to adapt to gas consumption fluctuations and lag in fault detection. This solution significantly improves efficiency and safety through intelligent adjustment and collaborative optimization.

[0090] A chemical enterprise's production workshop uses a reactor for polymerization reactions and requires a stable supply of compressed air to drive the agitator and convey materials. The daily gas consumption varies with the production batches: during the peak period (10:00 - 16:00), it is 400 m³ / h, and during the low period (20:00 - 4:00), it is 150 m³ / h. The electricity price is 0.85 yuan / kWh during the peak period and 0.35 yuan / kWh during the low period. High environmental humidity is likely to cause equipment failures. The system is installed on a piston air compressor with a cylinder body 1 capacity of 8 m³ and a control end 15 integrated control system. During initialization, the air pressure sensor 7, flow sensor 12, and vibration sensor collect data. The dynamic manifold optimization control module connects to the motor and the pilot-operated solenoid valve 5, and the user sets the gas supply target. During operation, the multi-source heterogeneous perception fusion module collects data at 10:00 (air pressure 0.7 MPa, flow 380 m³ / h, vibration 0.6 m / s²), generates a feature vector, and transmits it to each module. The dynamic manifold optimization control module generates an instruction (40% during the peak period), drives the coupling assembly 14 to drive the piston 17 to compress the gas, the isolation plate layer 23 drops to 3.5 m³, and the clip 20 limits the position. During the low period, it is adjusted to 75% and increases to 6 m³. The quantum probability fault prediction module detects the motor delay (0.3 s) caused by humidity. When the probability is 0.9, it reduces the load and adjusts the exhaust valve 4 to protect the equipment. The cross-domain energy collaborative scheduling module optimizes the power (70 kW during the peak period). During the low period, energy is saved by storing gas, and it is released during the peak period, saving 120,000 yuan annually. The distributed self-organizing communication module uploads data, and the administrator remotely monitors the position of the isolation plate layer 23, and network reorganization ensures stability. The adaptive meta-evolution module updates the strategy, controls the opening and closing of the intake valve 10 and the exhaust valve 4, and ensures the continuity of gas supply. In terms of effects, the abnormal capture rate is 95%, the adjustment accuracy is 98%, the energy consumption is reduced by 18%, the fault response is 0.5 seconds, the equipment life is extended by 20%, and the production interruption is reduced to 0.2 times per month. The traditional system is sensitive to humidity and has low energy efficiency. This solution improves reliability and economy through precise perception and energy efficiency optimization.

[0091] Case 3: Gas Supply for the Packaging Line of a Food Processing Factory

[0092] The packaging line of a certain food processing factory requires compressed air to drive the sealing machine and conveyor belt. The gas consumption varies with orders: during the peak period (9:00 - 15:00), it is 300 m³ / h; during the low period (18:00 - 2:00), it is 80 m³ / h. The electricity price is 0.8 yuan / kWh during the peak period and 0.3 yuan / kWh during the low period. High hygiene standards and low noise are required. The system is installed with a centrifugal air compressor. The capacity of the cylinder body 1 is 6 m³, and the control terminal 15 is implanted into the control system. During deployment, the sensor collects initial data, the user sets the target, and the system enters the operating state. The multi-source heterogeneous perception fusion module collects data at 9:00 (air pressure 0.6 MPa, flow rate 280 m³ / h, vibration 0.4 m / s²) and generates a feature vector for transmission. The dynamic manifold optimization control module generates an instruction (35% during the peak period), and the motor drives the piston 17 to compress the gas. The isolation plate layer 23 drops to 2.5 m³, and during the low period, it is adjusted to 70% and increases to 4.5 m³, with the clip 20 for limiting. The quantum probability fault prediction module detects the motor current fluctuation (12A). When the probability is 0.82, the load is reduced and the intake valve 10 is adjusted. The cross-domain energy collaborative scheduling module optimizes the power (60 kW during the peak period). During the low period, the gas storage is reduced by 10% for power consumption, saving 100,000 yuan annually. The distributed self-organizing communication module uploads data, and the administrator remotely adjusts the exhaust valve 4 with a delay of 50 ms. The adaptive meta-evolution module updates the strategy, controls the gas in and out, and reduces the noise to below 60 decibels. In terms of effects, the adjustment accuracy is 98%, the energy consumption is reduced by 20%, the fault response is 0.5 seconds, the vibration is reduced by 25%, the hygiene standards are met, and the order delivery rate is increased by 12%. The traditional system has high noise and unstable gas supply. This solution meets the needs of the food industry through intelligent adjustment and low-noise operation.

[0149] As Figures 1-7 shown, the following is the detailed hardware composition and hardware description of each module in Example 1:

[0150] Multi-source heterogeneous perception fusion module

[0151] Hardware composition: This module is mainly composed of a data acquisition unit and a data processing unit. The data acquisition unit includes a pressure sensor, a flow sensor, and a vibration sensor externally connected to the air compressor. The pressure sensor selects a high-precision piezoresistive pressure sensor, such as the ST3000 series of Honeywell, which can accurately measure the exhaust pressure, and its measurement accuracy can reach ±0.075%FS. The flow sensor uses an electromagnetic flow sensor, like the Promag series of Krohne, which can collect the intake flow in real time, and the measurement accuracy can reach ±0.5%. The vibration sensor selects an acceleration-type vibration sensor, such as the 352C66 model of PCB Piezotronics, which is used to capture the vibration acceleration of the device. The data processing unit uses a high-performance digital signal processor (DSP), such as the TMS320C6000 series of Texas Instruments, which has strong data processing capabilities and can quickly process the multi-source data collected.

[0152] Hardware function description: The pressure sensor monitors the exhaust pressure in real time, the flow sensor detects the intake air flow, and the vibration sensor captures the vibration of the device during operation. These sensors collect time-series data at a sampling frequency of 10 Hz and transmit the data to the data processing unit. The data processing unit uses a multi-modal fusion algorithm based on high-order singular value decomposition to construct multi-source data into a high-dimensional tensor representation, extracts cross-modal correlation features through decomposition, and then uses a dynamic graph convolutional network to enhance the spatio-temporal representation of abnormal signals. Finally, it outputs a high-dimensional fusion feature vector, which is updated once per second and transmitted to the subsequent module in the form of a structured data packet through the internal CAN bus, providing comprehensive and accurate operating status information for the system.

[0153] Dynamic manifold optimization control module

[0154] Hardware composition: This module mainly consists of a signal receiving unit, an algorithm processing unit, and an instruction output unit. The signal receiving unit is responsible for receiving the fusion feature vector transmitted from the multi-source heterogeneous perception fusion module and uses a high-speed data receiving interface chip, such as MAX3485, to ensure stable and fast data reception. The algorithm processing unit performs operations based on Riemannian manifold embedding and multi-agent inverse reinforcement learning and uses a field programmable gate array (FPGA), such as the Virtex series of Xilinx, which has powerful parallel computing capabilities and can quickly execute complex algorithms. The instruction output unit sends volume adjustment instructions to the execution components in the form of digital signals through the Modbus protocol interface and uses a Modbus communication chip, such as MCP2515 of Microchip Technology.

[0155] Hardware function description: After the signal receiving unit receives the fusion feature vector, the algorithm processing unit maps the high-dimensional features to the curved surface space through the Riemannian manifold embedding method, extracts the non-linear operation mode, combines multi-agent inverse reinforcement learning to infer the optimal strategy from historical data, generates a volume adjustment instruction, and the adjustment percentage range is 0 - 100%, which is updated every 500 ms. The instruction output unit sends the instruction to the execution components, such as the motor driving the coupling assembly, the lead screw assembly for adjusting the isolation plate layer, and the pilot-operated solenoid valve, etc., to control their working states and achieve precise adjustment of the air compressor volume. If a fault warning signal is received, the algorithm processing unit will switch to the conservative adjustment mode, reduce the motor speed and limit the movement of the isolation plate layer to ensure the safe operation of the device.

[0156] Quantum probability fault prediction module

[0157] Hardware Composition: The hardware of this module includes a data acquisition and reception unit, a calculation unit, and a signal output unit. In addition to receiving the fused feature vectors from the multi-source heterogeneous perception fusion module, the data acquisition and reception unit also collects the status data of the execution components, such as motor current sensors (such as the LA series Hall current sensors of LEM, which can accurately measure the motor current) and response delay detection circuits (composed of high-precision timers and signal comparators). The calculation unit uses a dedicated artificial intelligence calculation chip, such as the Jetson Xavier NX of NVIDIA, which has powerful computing power and can efficiently run the quantum random walk and variational Bayesian inference algorithms. The signal output unit transmits the fault warning signal in JSON format through the message queue via an event trigger mechanism, and uses an Ethernet communication module, such as the W5500 chip, to ensure stable signal transmission.

[0158] Hardware Function Description: The data acquisition and reception unit collects the fused feature vectors and the status data of the execution components in real time. The calculation unit simulates the propagation path of data anomalies through quantum random walk, combines variational Bayesian inference to estimate the probability distribution of fault occurrence, and generates a fault warning signal, which is updated every second. When the fault probability exceeds the threshold, the signal output unit triggers emergency adjustment, such as reducing the operating load of the motor to 50% by controlling the motor, adjusting the opening degree of the pilot-operated solenoid valve 5, or starting the standby air compressor. In severe cases, it executes a safe shutdown to protect the cylinder body and piston structure and ensure production safety.

[0159] Cross-domain Energy Collaborative Scheduling Module

[0160] Hardware Composition: The hardware of this module mainly consists of a data acquisition unit, an algorithm operation unit, and a parameter output unit. The data acquisition unit receives the fused feature vectors, volume adjustment instructions, and external energy price data. It uses a data acquisition card (such as the PCI-1716L of Advantech, which can collect various types of data) to obtain internal data and a network communication module (such as a 4G communication module, such as the EC200U series of Quectel, which can obtain external energy price data in real time) to obtain external data. The algorithm operation unit uses dynamic game equilibrium and multi-objective differential evolution algorithms to maximize energy efficiency, and uses a high-performance server-level CPU, such as the Intel Xeon series processors, which have powerful computing capabilities. The parameter output unit transmits the optimized parameters in the form of a structured array through shared memory, and uses a cache chip (such as the K4B4G1646E-HYK0 of Samsung) to construct the shared memory.

[0161] Hardware Function Description: The data acquisition unit acquires various types of data in real time. The algorithm operation unit analyzes the interaction effect between operation parameters and energy consumption through dynamic game equilibrium, searches for the optimal solution using the multi-objective differential evolution algorithm, and outputs optimization parameters including power distribution and volume targets, which are updated every 5 minutes. The parameter output unit transfers the optimization parameters to the dynamic manifold optimization control module and the adaptive meta-evolution module to guide the adjustment of the motor speed and the position of the isolation plate layer, increase the gas storage capacity during the low period of energy cost, optimize the release during the peak period, coordinate the piston compression and the gas inlet and outlet, and achieve the maximum energy efficiency.

[0162] Distributed Self-Organizing Communication Module

[0163] Hardware Composition: The hardware of this module consists of a signal reception and processing unit, a network optimization unit, and a data transmission unit. The signal reception and processing unit receives fault warning signals, optimization parameters, and external remote instructions, and uses a high-speed data reception chip and a microcontroller (such as the STM32 series of STMicroelectronics) for signal processing. The network optimization unit dynamically adjusts the communication network structure through chaotic topology optimization and uses a programmable logic device (such as the ECP5 series of Lattice) to achieve flexible adjustment of the network topology structure. The data transmission unit verifies the data integrity using post-quantum signature technology, uploads the encrypted data to the remote monitoring center every second, and uses an encrypted communication module (such as an RSA encryption chip) to ensure data security.

[0164] Hardware Function Description: After the signal reception and processing unit receives various signals, the network optimization unit dynamically adjusts the communication network structure according to the chaotic topology optimization algorithm and selects the optimal transmission path. The data transmission unit verifies the data integrity using post-quantum signature technology, uploads the encrypted data to the remote monitoring center, and at the same time decrypts the external instructions and transfers them to the dynamic manifold optimization control module through the message queue. When a network anomaly is detected, the network optimization unit automatically reorganizes the network, and the signal reception and processing unit records the event log to ensure the security and stability of data transmission and achieve the remote monitoring and collaborative management of the air compressor.

[0165] Adaptive Meta-Evolution Module

[0166] Hardware Composition: The hardware of this module mainly includes a data storage and reading unit, an algorithm execution unit, and a policy output unit. The data storage and reading unit stores the fused feature vectors, optimization parameters, and historical operation data in the local database. The local database is constructed using a large-capacity hard disk (such as the Purple series of Western Digital) and a high-performance solid-state drive (such as the 980PRO series of Samsung for cache acceleration), and a disk array controller (such as the 9361-8i of LSI) is used for data management. The algorithm execution unit continuously improves the policy using metaheuristic transfer learning and chaotic whale optimization algorithm. A graphics processing unit (GPU), such as the RadeonPro series of AMD, is adopted, and its parallel computing ability helps to accelerate the operation of complex algorithms. The policy output unit distributes the optimized policy in the form of a configuration file through the internal API, and a microcontroller (such as the RL78 series of Renesas Electronics) is used to control the API interface communication.

[0167] Hardware Function Description: The data storage and reading unit stores and reads relevant data in real time. The algorithm execution unit extracts general knowledge from relevant tasks through metaheuristic transfer learning, combines the chaotic whale optimization algorithm to search for global optimal parameters, generates an optimized policy including adjustment thresholds and learning rates, and updates it once an hour. The policy output unit distributes the optimized policy to the dynamic manifold optimization control module and the cross-domain energy collaborative scheduling module to ensure the adaptability of the long-term operation of the air compressor, continuously optimize its operation policy, and improve the overall performance.

[0168] It should be noted that in the appendix Figure 2 In:

[0169] The first sub-figure is the exhaust pressure (MPa): Around 0 - 500s, the exhaust pressure is maintained at about 1.5MPa, and then the pressure drops sharply and stabilizes at about 1MPa. The red vertical line may represent the time point when a certain key event occurs, resulting in a mutation in the exhaust pressure.

[0170] The second sub-figure is the intake flow rate (m³ / min): The overall fluctuation is small, fluctuating between 9.5 - 10.5m³ / min, indicating that the intake flow rate is relatively stable and there are no significant increases or decreases.

[0171] The third sub-figure is the vibration acceleration (g): There is an obvious change around 500s. Before that, the vibration acceleration is relatively low, and then it increases significantly and remains at a high level, which may imply a change in the operating state of the equipment, such as increased vibration caused by wear and loosening of internal components. The red vertical line is consistent with the time point in the exhaust pressure diagram, and it may be a variety of parameter changes caused by the same event.

[0172] In the appendix Figure 3 In:

[0173] The first sub - figure is the gas storage capacity adjustment (m³): The gas storage capacity fluctuates continuously throughout the process. There is a certain amplitude of fluctuation around 0 - 1000s, and then it continues to fluctuate, indicating that the system is continuously making adaptive adjustments to the gas storage capacity according to certain conditions (possibly gas consumption demand, etc.).

[0174] The second sub - figure is the failure probability: The failure probability is relatively low in the early stage, suddenly rises significantly around 500s and exceeds the threshold (the dotted line in the figure represents the threshold), and then remains at a relatively high level, indicating that an abnormal situation that may lead to failure occurred in the equipment around 500s and this abnormality persists.

[0175] The third sub - figure is the energy consumption cost (×10³ yuan): The energy consumption cost first rises, then falls, reaches the lowest around 2000 - 2500s, and then starts to rise again. This may be related to factors such as the system's adjustment of the gas storage capacity, the operating state of the equipment (such as the energy consumption may change during the stage of rising failure probability), and the energy price, etc.

[0176] Generally speaking, these charts reflect the changes in some key parameters of the adaptive variable - volume intelligent air compressor during operation, showing the responses of each parameter when the system faces certain situations (such as the event around 500s) and the performance of the system in terms of gas storage capacity adjustment, fault warning, and energy consumption control.

[0177] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
