Abstract
Description
Technical Field
[0001] This invention belongs to the field of Internet of Things (IoT) technology, specifically referring to an IoT-based intelligent monitoring and control system for the energy efficiency of refrigeration units. Background Technology
[0002] With the acceleration of urbanization and increasing pressure on energy consumption, the refrigeration system, as a major component of building energy consumption, directly affects the overall energy utilization efficiency. Traditional refrigeration unit control systems mostly rely on preset thresholds or simple feedback control, lacking the ability to perceive and dynamically respond to environmental disturbances, equipment aging, and load fluctuations in real time, resulting in low energy efficiency and accelerated equipment wear.
[0003] However, existing intelligent monitoring and control systems for refrigeration unit energy efficiency still have certain shortcomings. Current technologies rely on traditional sensors to collect environmental parameters, and their detection accuracy and sensitivity are limited by the physical characteristics of the sensors. They are unable to capture the nonlinear response of weak environmental disturbances, lack compensation mechanisms for non-target interference, and the collected data is easily contaminated by external noise. The dynamic range and resolution are insufficient, making it impossible to provide high-fidelity input for energy efficiency modeling. Using classical algorithms or shallow machine learning models for energy efficiency prediction makes it difficult to handle the multidimensional coupling relationship between environmental parameters and refrigeration system energy efficiency. In the face of nonlinear behavior in chaotic environments, they lack effective dynamic trajectory prediction capabilities and cannot capture the evolution trend of the system under critical states. They often use a single objective function, ignoring the multidimensional trade-off between energy efficiency and system stability. Therefore, an IoT-based intelligent monitoring and control system for refrigeration unit energy efficiency is proposed. Summary of the Invention

[0118] when When the formula degenerates into Prioritize energy efficiency, when When the formula degenerates into Prioritize minimizing entropy production for all feasible... Combinatorial calculation The solution set corresponding to the minimum value is retained as the Pareto optimal solution.
[0119] Preferably, the holographic digital twin module receives real-time sensor data from the physical devices of the refrigeration system, constructs a high-precision virtual model based on BIM, GIS and 3D modeling technologies, and maps the key state variables of the physical system and the digital twin model to quantum states through a quantum entanglement synchronization protocol;
[0120] Quantum entanglement pairs enable instantaneous state synchronization between physical devices and virtual models. When the state of the physical system changes, the quantum entanglement synchronization protocol immediately triggers the corresponding parameter update of the digital twin model. The digital twin model then recalculates the system performance indicators and generates control suggestions based on the corrected state.
[0121] By leveraging the simulation capabilities of digital twin models, the nonlinear characteristics of physical systems can be dynamically calibrated, correcting deviations in the virtual model.
[0122] Working principle: Multidimensional environmental parameters are collected through a quantum tunneling effect sensor. The nonlinear response characteristics of the quantum system are used to convert environmental disturbances into changes in the energy levels or tunneling probability of the quantum state. The sensor excites the quantum system into a superposition state through laser or electromagnetic field and records the ground state characteristics as a reference value to achieve environmental compensation such as temperature and electromagnetic interference, and eliminate non-target interference. When environmental parameters are disturbed, the energy levels or tunneling probability of the quantum system change nonlinearly. These changes are captured by quantum measurement equipment and converted into quantifiable signals. The multidimensional environmental parameter signals are processed by a chaotic analysis algorithm to extract the Lyapunov exponent and phase space reconstruction features, calculate the chaotic coefficients of each parameter, and finally form an environmental chaotic coefficient matrix. Noise is removed by wavelet transform, and high-frequency chaotic features are preserved.
[0123] The energy efficiency tensor modeling module receives the environmental chaos coefficient matrix and maps its elements to the input variables of the refrigeration system. Based on the system's operating characteristics, a three-dimensional energy efficiency tensor is defined. The environmental chaos coefficients and real-time energy efficiency data are fused and filled into the tensor. Through tensor decomposition, the core tensor and factor matrix are extracted to represent the low-dimensional feature vectors of energy efficiency state, time dimension, and environmental parameters, respectively. The reconstructed three-dimensional energy efficiency coupling tensor associates the features of each dimension through the interaction terms of the core tensor, and calculates the absolute value of the elements of the core tensor as a quantitative indicator of the coupling strength among energy efficiency state, time, and environmental parameters. The phase space trajectory prediction module is based on the three-dimensional energy efficiency coupling... Tensors map environmental chaos coefficients to quantum states. By initializing the quantum state and multiplying it with tensors, a target Hamiltonian containing the physical constraints of the refrigeration system is constructed in the initial quantum state. Combined with transverse field terms, the quantum tunneling effect is simulated, allowing the system to cross local energy efficiency extremes. The quantum annealing processor initializes the qubits as a uniform superposition state and gradually reduces the transverse field strength, allowing the quantum state to evolve to a low-energy state. After annealing, the energy efficiency state is sampled by measuring the quantum state. Combined with probability amplitude weighting, phase space coordinate points are generated to form a phase space topological trajectory diagram of future energy efficiency. Combined with real-time environmental data, the trajectory is dynamically corrected to reveal the nonlinear behavior of the refrigeration system in a chaotic environment.
[0124] Based on the analysis of the curvature characteristics of the phase space topological trajectory diagram using the critical state fuzzy control module, and combined with the Lyapunov exponent in the environmental chaos coefficient matrix, it is determined whether the system is close to the chaotic critical state. The curvature characteristics are quantized into fuzzy sets, and the Lyapunov exponent is mapped to fuzzy linguistic variables. The degree of fuzziness is quantified through membership functions to dynamically generate a fuzzy control rule matrix. The priority of the control rules is adjusted by combining the exponential decay term and the curvature gain term, reducing the sensitivity in chaotic states and enhancing the response capability to sudden changes. Finally, new rules are automatically generated through fuzzy clustering, the control strategy is dynamically updated, and the balance between fuzzy control and default control is achieved. Contribution: The dissipative structure optimization module, based on a fuzzy control rule matrix, establishes a coupled model of the compressor and refrigerant flow, distinguishes between reversible and irreversible processes, calculates entropy change through a virtual reversible path, and utilizes the local equilibrium assumption of non-equilibrium thermodynamics to decompose the system into sub-regions, calculates and sums the entropy changes, establishes a mapping relationship between control parameters and entropy change, constructs a multi-objective optimization problem with compressor speed and refrigerant flow as decision variables, filters non-dominated solutions through dominance relationships, forms a Pareto optimal solution set, dynamically adjusts the fuzzy rule matrix, and regenerates the solution set in conjunction with real-time environmental disturbances, balancing energy efficiency ratio and minimizing entropy production to achieve refrigeration. The system performs global optimization under complex operating conditions. Real-time sensor data from physical equipment is used to construct a high-precision virtual model based on BIM, GIS, and 3D modeling technologies. A quantum entanglement synchronization protocol is used to achieve instantaneous synchronization of key state variables between the physical system and the digital twin model through quantum entanglement pairs. When the state of the physical system changes, the protocol triggers an update to the virtual model parameters.
