Description

Technical Field

[0001] This application relates to the field of thermodynamic engineering monitoring and energy efficiency management technology, and in particular to a high-entropy production area control system, method, electronic device, storage medium and program product. Background Technology

[0002] During the operation of industrial equipment, the entropy increase caused by energy dissipation directly affects the system's energy efficiency. Existing methods for monitoring the energy efficiency of industrial equipment rely on independently deployed infrared thermometers, differential pressure gauges, and particle image velocimetry systems. Due to the lack of a unified triggering mechanism, there are millisecond-level time differences in the temperature field, pressure field, and flow field data.

[0003] Current technologies suffer from three significant drawbacks: First, traditional monitoring uses independent sensors to collect temperature, pressure, and flow field data separately, making it difficult to fuse and calculate these data due to asynchronous acquisition times. Second, existing methods rely on offline CFD simulations to infer entropy production rates, with calculations taking hours to days, failing to capture dynamic irreversible losses such as transient eddies and turbulence. Third, existing sensors only output single physical quantity measurements, lacking the ability to directly reflect the degree of energy dissipation through entropy production rate output. Particularly in critical equipment such as turbomachinery and heat exchangers, the inability to locate the spatial coupling relationship between high-entropy production regions and eddy current regions in real time leads to delayed energy loss warnings and inaccurate control measures. Although existing technologies have attempted to improve monitoring accuracy through infrared thermometry optimization and flow field visualization, none have established a real-time multi-physics fusion entropy production rate calculation model, and even less so a dynamic control mechanism based on entropy production thermograms.

[0050] Figure 2 This is a flowchart of the high-entropy production region regulation method proposed in the embodiments of this application;

[0051] Figure 3 This is a schematic diagram of the structure of the electronic device proposed in the embodiments of this application. Detailed Implementation

[0052] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] In existing technologies, the field of industrial equipment energy efficiency monitoring has long faced the problem of insufficient synchronization of multi-physics field data. Traditional methods rely on independently deployed infrared thermometers, differential pressure gauges, and particle image velocimetry systems. Due to the lack of a unified triggering mechanism, millisecond-level time differences exist between temperature, pressure, and flow field data. For example, in the turbine guide vane flow channel, the local entropy increase phenomenon caused by transient eddies is often difficult to accurately capture due to asynchronous data acquisition. This results in a significant deviation between the entropy production distribution obtained from offline simulation calculations and actual operating conditions, failing to provide a reliable basis for real-time energy efficiency control.

[0054] To address the aforementioned issues, a high-entropy production area control system, method, electronic device, storage medium, and program product are provided.

[0055] Reference Figure 1 This application proposes a high-entropy production region regulation system, comprising:

[0056] The laser trigger pulse module 10 is used to send synchronous trigger pulses to each multiphysics sensor so that each multiphysics sensor synchronizes its data acquisition time.

[0057] The data acquisition module 20 is used to acquire multi-dimensional physical field data collected in real time by each multi-physics sensor.

[0058] The entropy production calculation module 30 is used to calculate the real-time entropy production rate and vortex modulus of each entropy production region of each subsystem in the target system based on multi-dimensional physical field data, determine the coordinates of the vortex region and vortex core of each subsystem according to the preset vortex modulus threshold, and generate a heat map of the entropy production rate distribution of each subsystem based on the real-time entropy production rate of each entropy production region of each subsystem and the coordinates of the vortex region and vortex core of each subsystem.

[0059] The adjustment and control module 40 is used to locate the high entropy production area that overlaps with the eddy region in each subsystem based on the heat map of the entropy production rate distribution of each subsystem, generate adjustment and control instructions for the high entropy production area in each subsystem, and drive the real-time entropy production rate of the eddy region of each subsystem to decrease.

[0060] The laser trigger pulse module 10 is a device that coordinates the sampling timing of multiple sensors through short-period optical signals. Specifically, it can be implemented using a nanosecond-level laser diode array, which eliminates the data phase difference caused by clock drift in traditional independent sensors. The data acquisition module 20 is a multi-channel acquisition circuit integrating temperature, flow rate, and pressure signals, such as an FPGA-based parallel sampling architecture, used to ensure the consistency of multidimensional physical quantities in the spatiotemporal dimensions. The entropy production calculation module 30 is an edge processor embedding a vortex-entropy production coupling algorithm, which calculates the viscous dissipation function by analyzing the velocity gradient tensor and dynamically identifies the spatial coordinates of the vortex core. The adjustment and control module 40 is an execution unit with real-time feedback control function, such as a programmable logic controller combined with a PID algorithm, used to generate guide vane angle adjustment signals based on the entropy production distribution heatmap.

[0061] Specifically, during system operation, all sensors are first triggered by laser pulses to synchronously acquire data. Temperature gradient, velocity field, and pressure field data are spatiotemporally aligned and then input into the edge computing unit. The calculation module delineates the vortex region boundary based on a preset vortex modulus threshold and generates a two-dimensional thermogram by combining it with the real-time entropy production rate. When an abnormal peak in entropy production rate is detected in a certain guide vane channel region, the adjustment module automatically calculates the guide vane deflection angle correction amount and changes the channel geometry through the actuator to suppress vortex intensity, thereby reducing energy dissipation in that region.

[0062] This application's embodiments compress the entropy production analysis delay to the millisecond level through multi-sensor hard real-time synchronization and edge computing. Microsecond-level time synchronization accuracy is achieved through laser trigger pulses, enabling accurate capture of the spatiotemporal correlation between transient eddies and entropy increase processes. This allows for in-situ real-time measurement and dynamic control of local entropy production rates in industrial equipment, solving the entropy production calculation error problem caused by data asynchrony in traditional methods. The system can automatically identify the spatial overlap between eddy current regions and high-entropy production regions, and quickly suppress energy dissipation sources through a closed-loop control mechanism, providing a reliable technical means for real-time energy efficiency management.

[0063] In some embodiments, the multidimensional physical field data includes at least temperature gradient data.

[0064] The entropy production calculation module 30 includes at least a sampling unit and an entropy production rate calculation unit.

[0065] The sampling unit is used for:

[0066] Spatiotemporal alignment of the multidimensional physical field data of each entropy-producing region in each subsystem is performed to obtain the standard multidimensional physical field data of each entropy-producing region in each subsystem.

[0067] Based on the temperature gradient data of each entropy-producing region in each subsystem, the attention weight of each entropy-producing region in each subsystem is calculated according to the following formula:

[0068]

[0069] Where α refers to the attention weight of each entropy-producing region in each subsystem. This refers to the temperature gradient data, where k refers to the preset parameter.

[0070] Based on the attention weight of each entropy-producing region in each subsystem, determine the sampling frequency and sampling density of each entropy-producing region in each subsystem.

[0071] Based on the sampling frequency and sampling density of each entropy-producing region in each subsystem, the standard multidimensional physical field data of each entropy-producing region in each subsystem are sampled to obtain the sampling data of each entropy-producing region in each subsystem.

[0072] The entropy productivity calculation unit is used for:

[0073] Calculate the real-time entropy production rate of each entropy production region in each subsystem based on the sampled data of each entropy production region in each subsystem.

[0074] Temperature gradient data refers to the rate of temperature change within a region collected by sensors. Specifically, this can be achieved using an infrared thermal imaging module with multi-point measurements at a preset resolution, reflecting the energy dissipation distribution during heat conduction. Attention weight is a quantization parameter dynamically adjusted based on the temperature gradient. It can be calculated using normalization and an exponential function, used to identify high-energy-dissipation areas and guide sampling strategy optimization. Sampling frequency refers to the number of times data is collected from a specified area per unit time. This can be achieved by controlling the sensor trigger timing with a programmable clock signal, balancing data accuracy and system resource consumption. Sampling density refers to the number of data collection points per unit area or volume. This can be achieved by adjusting the spatial distribution density of the sensor array, improving the measurement resolution in key areas.

[0075] Specifically, during data acquisition, the multiphysics sensor array first performs spatiotemporal alignment on data such as temperature, flow rate, and pressure difference to eliminate coordinate offsets caused by differences in sensor response times. Attention weights for each region are calculated based on temperature gradient data; higher weight values ​​indicate more significant energy dissipation in that region. For regions with weights below a preset threshold, standard sampling frequency and density are used to reduce computational load; for regions with weights above the preset threshold, a high sampling mode is automatically switched to capture transient thermodynamic characteristics. The sampled data is input into the entropy yield calculation unit, which calculates the entropy yield value reflecting local irreversible losses by fusing the viscous dissipation function with the heat conduction equation.

[0076] This application's embodiments utilize a temperature gradient-driven dynamic sampling mechanism to increase data acquisition density in the early stages of vortex core formation, thereby reducing entropy production calculation errors for key phenomena such as boundary layer separation and secondary flow. It effectively identifies transient high-entropy production regions during industrial equipment operation, such as the formation process of localized high-temperature zones within a gas turbine combustion chamber. Through an adaptive sampling strategy, it captures abrupt temperature gradient changes on a millisecond-level timescale, providing accurate real-time data support for suppressing energy dissipation in hot-end components.

[0077] In some embodiments, the sampling frequency includes at least a standard sampling frequency and a high sampling frequency, and the sampling density includes at least a standard sampling density and a high sampling density.

[0078] Based on the attention weight of each entropy-producing region in each subsystem, determine the sampling frequency and sampling density of each entropy-producing region in each subsystem, including:

[0079] If the attention weight of a certain entropy-producing region in each subsystem is less than a preset weight threshold, the sampling frequency and sampling density of the multi-dimensional physical field data of that entropy-producing region are maintained at the standard sampling frequency and standard sampling density.

[0080] If the attention weight of a certain entropy-producing region in each subsystem is greater than a preset weight threshold, the sampling frequency of the multi-dimensional physical field data of that entropy-producing region is increased to a high sampling frequency, and the sampling density of the multi-dimensional physical field data of that entropy-producing region is increased to a high sampling density.

[0081] The standard sampling frequency refers to the periodic sampling rate that meets the basic data acquisition requirements. This can be achieved by using a fixed time interval for data acquisition, such as acquiring data once every millisecond. The high sampling frequency refers to an increased sampling rate for critical areas. This can be achieved by using hardware triggering with dynamically adjusted clock cycles, such as acquiring data once every microsecond. The standard sampling density refers to the number of basic data acquisition points per unit space. This can be achieved by using a uniformly distributed sensor array layout. The high sampling density refers to the increased density of data acquisition points for critical areas. This can be achieved by using a dynamic focusing mode of a programmable sensor array. The preset weight threshold is the critical value used to distinguish between ordinary and critical areas. This can be obtained through experimental calibration or training with a machine learning model.

[0082] Specifically, when the attention weight corresponding to the temperature gradient data in a certain entropy-producing region is lower than a preset threshold, the system maintains standard sampling parameters to reduce resource consumption. For example, in a homogeneous flow region, standard sampling frequency and density are sufficient to meet data accuracy requirements. When the attention weight exceeds the preset threshold, the system automatically switches to a high sampling mode. For example, in vortex cores or boundary layer regions, increasing the sampling frequency and density can capture transient vortex evolution processes and abrupt temperature gradient changes. This dynamic adjustment mechanism is executed in real time through edge computing units to ensure that the physical field data of high-entropy-producing regions are completely recorded.

[0083] This application's embodiments achieve optimized allocation of data acquisition resources by introducing an attention weight threshold judgment mechanism. It can automatically identify high-gradient regions and improve data acquisition accuracy during industrial equipment operation, effectively avoiding the problem of missed sampling of transient eddy current features. Simultaneously, by dynamically adjusting sampling parameters, it reduces resource consumption in non-critical areas, improving the overall system operating efficiency.

[0084] In some embodiments, the multidimensional physical field data may include at least flow velocity data and pressure difference data.

[0085] The process of determining the real-time entropy production rate of each entropy production region in each subsystem includes:

[0086] Based on temperature gradient data, vorticity data, and pressure difference data, the real-time entropy production rate of each entropy production region of each subsystem is calculated using the following formula:

[0087]

[0088] Where, φ visc The viscous dissipation function, S″ gen This refers to the real-time entropy production rate of each entropy production region, u refers to the flow velocity component in the x-direction, v refers to the flow velocity component in the y-direction, λ refers to thermal conductivity, and T refers to thermodynamic temperature. Temperature gradient, μ refers to dynamic viscosity, ζ refers to volumetric viscosity, and ΔP refers to pressure difference data.

[0089] Among them, temperature gradient data refers to the local temperature change rate data acquired by the infrared thermal imaging module, specifically implemented using a high-temperature resistant sensor array with a resolution of ±0.1℃, used to reflect the entropy production component caused by heat conduction. Flow velocity data refers to the flow velocity field distribution information obtained by the particle image velocimetry module, specifically implemented using a vibration-resistant PIV system, used to calculate the entropy production component caused by viscous dissipation. Pressure difference data refers to the pressure gradient data measured by the microchannel pressure difference sensing array, specifically implemented using a miniature sensor with a response time ≤1ms, used to reflect the impact of pressure pulsation on entropy production. Thermal conductivity λ refers to the thermal conductivity coefficient of the material, which can be obtained by matching a preset physical property parameter library. Dynamic viscosity μ and volumetric viscosity ζ refer to the viscous characteristic parameters of the fluid, which can be dynamically adjusted according to real-time temperature data.

[0090] Specifically, in calculating the real-time entropy production rate, temperature gradient data is first acquired synchronously via an infrared thermal imaging module. Combined with the flow velocity components u and v provided by the particle image velocimetry module, the spatial gradient of the velocity field is derived. ΔP data collected by the differential pressure sensing array is used to quantify the contribution of pressure pulsations to energy dissipation. The viscous dissipation function is calculated using the quadratic term of the velocity gradient tensor, reflecting the mechanical energy loss caused by fluid shearing. The product of thermal conductivity λ and the square term of the temperature gradient characterizes the irreversible loss caused by heat conduction. The product of bulk viscosity ζ and the square term of the velocity divergence is used to capture energy dissipation during fluid compression or expansion. By fusing multiphysics data and using the above formulas for real-time calculation, both thermodynamic and fluid dynamic entropy production mechanisms can be simultaneously covered.

[0091] This application embodiment utilizes multi-sensor data fusion and real-time calculation to synchronously input temperature gradient, flow velocity field, and pressure difference data into the entropy production rate calculation formula. This ensures that the calculation results simultaneously incorporate the combined effects of viscous dissipation and heat conduction, solving the problem that existing technologies cannot reflect the coupling effect of dynamic flow fields and temperature fields in real time. It enables in-situ real-time measurement of local entropy production rate in industrial equipment, accurately quantifying the energy dissipation intensity in high-gradient regions such as vortex zones and boundary layers. By fusing multi-dimensional physical field data, it avoids entropy production calculation errors caused by measurement deviations of single physical quantities, providing high-precision data support for turbine guide vane angle adjustment and flow channel structure optimization, thereby effectively reducing irreversible losses during system operation.

[0092] In some embodiments, the adjustment control module 40 further includes at least a coordinate adjustment unit, which is used for:

[0093] Based on the real-time entropy production rate of each entropy production region in each subsystem, determine the extreme point of the entropy production rate of each entropy production region.

[0094] The vortex core position error of each subsystem is determined based on the spatial offset between the vortex core coordinates and the extreme point of entropy production rate of each subsystem.

[0095] Based on the vortex core position error, the vortex core coordinates of each subsystem are corrected, generating the corrected vortex core coordinates of each subsystem, and synchronized to the entropy yield distribution heatmap.

[0096] Among them, the extreme point of entropy productivity refers to the coordinate position where the entropy productivity reaches a local maximum in the spatial distribution. This can be achieved using gradient descent or peak detection algorithms to identify the core region where entropy productivity abnormally increases. Spatial offset refers to the distance difference between the vortex core coordinates and the extreme point of entropy productivity in the spatial coordinate system. This can be achieved through Euclidean distance calculation or vector difference modulus calculation, used to quantify the degree of deviation between the vortex center and the high-entropy-productive region. Vortex core position error refers to the positioning deviation between the vortex core position derived from the spatial offset and the actual high-entropy-productive region. This can be achieved using normalization or weighted averaging methods, used to guide the magnitude and direction of coordinate correction.

[0097] Specifically, during operation, the coordinate adjustment unit first locates the peak entropy productivity point within each entropy productivity region using an extreme value search algorithm based on real-time entropy productivity data. Then, it spatially compares the original vortex core coordinates of the subsystem with the extreme points of entropy productivity, calculating the offset between them. If the offset exceeds a preset tolerance threshold, a coordinate correction is generated based on the offset direction and magnitude, and the vortex core coordinates are iteratively adjusted. The corrected vortex core coordinates are updated in real-time to the entropy productivity distribution heatmap, thereby ensuring the accurate spatial mapping between the vortex region and the high-entropy productivity region.

[0098] This application embodiment achieves online calibration of the vortex core position by dynamically matching the extreme points of real-time entropy production rate with the coordinates of the vortex core, effectively eliminating positioning errors caused by transient changes in the flow field. It solves the problem of inaccurate spatial mapping between the vortex core position and the high-entropy production region in existing technologies. The real-time coordinate correction mechanism improves the accuracy of the entropy production rate distribution heatmap, providing a reliable spatial positioning basis for the generation of subsequent adjustment and control commands, thereby ensuring the precise execution of system energy efficiency optimization measures.

[0099] In some embodiments, the adjustment and control module 40 includes at least an instruction generation unit, which is used for:

[0100] Based on the heatmap of entropy yield distribution for each subsystem, the location of each high-entropy yield region is determined.

[0101] When a high-entropy productivity region is located within the turbine guide vane passage, the angle correction is determined by a PID controller according to the following formula, based on the real-time entropy productivity of this high-entropy productivity region and the optimal entropy productivity under rated operating conditions:

[0102]

[0103] Among them, K p K i K d Here, φ is the preset control coefficient, and φ is the real-time entropy yield of this high-entropy yield region. ref This represents the optimal entropy production rate under rated operating conditions.

[0104] Based on the angle correction amount of the high-entropy yield region, an adjustment control command for the high-entropy yield region is generated. The adjustment control command is used to adjust the guide vane angle of the high-entropy yield region.

[0105] The PID controller refers to a regulator based on proportional, integral, and derivative control. Specifically, it can be implemented using an incremental digital PID algorithm, dynamically adjusting the guide vane angle based on the deviation between the real-time entropy production rate and the optimal entropy production rate. The angle correction amount refers to the mechanical angle adjustment required for the guide vane, which can be achieved by converting the output value of the PID controller into the displacement of the mechanical actuator, used to precisely correct the spatial attitude of the guide vane. Guide vane angle adjustment refers to changing the installation angle of the turbine guide vane, which can be achieved by using a servo motor to drive the guide vane rotation mechanism, adjusting the flow field distribution within the flow channel by changing the guide vane angle.

[0106] Specifically, when the entropy production rate distribution heatmap shows a high entropy production rate region located in the turbine guide vane flow channel, the real-time entropy production rate and the optimal entropy production rate under rated operating conditions are input to the PID controller. The PID controller calculates the combined output of the proportional, integral, and derivative terms based on the deviation between the two, generating a corresponding angle correction. This correction is converted into a control signal for the guide vane drive mechanism, driving the guide vane to rotate by a specific angle, thereby changing the vortex morphology and velocity distribution within the flow channel and reducing viscous and thermal dissipation in that region. For example, when high entropy production is detected in the guide vane trailing edge region, the guide vane angle is adjusted to weaken flow separation and reduce turbulent dissipation.

[0107] This application embodiment achieves dynamic angle adjustment by driving PID control with real-time entropy production data. Continuous optimization of entropy production rate is achieved through closed-loop control. It can respond in real-time to changes in entropy production rate within the flow channel, automatically adjusting the guide vane angle to suppress eddy current dissipation, effectively reducing energy loss in high-entropy production regions and improving turbine operating efficiency. This solves the technical problem of traditional guide vane adjustment lagging behind actual operating conditions, avoiding continuous performance degradation caused by a fixed guide vane angle.
