[0002] As a core device for separating mixtures, centrifuges have been upgraded from traditional centrifugal separation to high-precision biopreparation in the pharmaceutical and biological fields. For example, the STC series of fully automatic tubular centrifuges achieve nanoscale material separation through ultra-high-speed rotation at 100,000 rpm and are widely used in the production of biological products such as mRNA vaccines and monoclonal antibodies. However, as bioprocesses place increasing demands on separation accuracy and safety, existing technologies have limited the ability to perform real-time analysis, low dynamic visualization accuracy, poor adaptability to parameter control, and low efficiency in multi-device collaboration.

[0103] Furthermore, it should be noted that the hybrid modeling is adapted to the scenario: in the biopharmaceutical scenario, the hybrid modeling module 202 learns the rheological properties of the protein solution through LSTM and dynamically adjusts the correction coefficient of the centrifugal force field theoretical model.
[0104] In this embodiment, it should also be noted that the real-time monitoring and visualization unit 300 includes a multi-physics field simulation engine 301, an AR augmented reality module 302, a risk warning visualization module 303, and a historical data backtracking module 304, wherein: the multi-physics field simulation engine 301: based on CFD and FEA technology, simulates the flow field distribution, temperature gradient and rotor stress changes in the centrifugal cavity in real time to generate a three-dimensional dynamic simulation model; the AR augmented reality module 302: is used to superimpose equipment parameters, fault points and maintenance guides in the operator's field of view through smart glasses and spatial positioning technology, supporting contactless remote collaboration; the risk warning visualization module 303: is used to present the equipment status in the form of heat maps and three-dimensional vector maps through WebGL technology, and abnormal parameters automatically trigger red, yellow and green color warnings and mark the spatial location; the historical data backtracking module 304: based on the time series database, supports multi-dimensional data query and generates traceable audit reports.

AR visualization interaction mechanism: The operator can use the gesture recognition function of the smart glasses to call up the flow field slice diagram of any cross section of the centrifuge in real time. For example, when viewing the nanocarbon separation process, the gesture sliding can switch to display the particle concentration cloud map at different speeds. The red area automatically marks the agglomeration risk point and displays the optimal speed adjustment suggestion (such as reducing from 10,000 RPM to 8,500 RPM).

Dynamic parameter optimization module 403 integrates a genetic algorithm with an expert knowledge base to automatically optimize the centrifuge speed and temperature profile, improving separation efficiency and reducing energy consumption. Safety interlock control module 404, based on the fail-safe principle, automatically triggers emergency shutdown and valve closure protection actions when parameters exceed limits.
[0108] Among them, it should be noted that the fuzzy adaptive control module 401 and the dynamic parameter optimization module 403 form a dual-loop adjustment system of "parameter self-tuning-process self-optimization", the multi-agent collaboration module 402 realizes the distributed scheduling and fault-tolerant migration of cluster tasks based on blockchain smart contracts, and the safety interlock control module (404) monitors the parameters of the entire process in real time and implements hierarchical protection.
[0109] Furthermore, it is important to note the construction of the fuzzy adaptive control rule base: For cell culture scenarios, the fuzzy controller establishes a "shear sensitivity-speed adjustment" rule base: When the shear sensitivity index of the CHO cell culture fluid is detected to be greater than 0.8, the speed adjustment gradient is automatically set to 50 RPM / minute (the conventional gradient is 200 RPM / minute) and the temperature compensation coefficient is increased (for every 100 RPM decrease, the temperature increases by 0.5°C) to maintain cell viability above 90%. A blockchain-based evidence storage mechanism for multi-agent collaboration: The task scheduling records of each centrifuge are stored in blocks, containing information such as task ID, allocation time, execution parameters, and efficiency indicators.

[0112] Furthermore, it is important to note the load balancing strategy for cloud-edge collaboration: the cloud server is responsible for historical data mining and global optimization (e.g., analyzing the energy consumption data of 100 centrifuges to generate quarterly energy-saving reports), while the edge device handles real-time control (e.g., millisecond-level vibration response).
