Description

[0002] In the precision machining of low-temperature brittle materials (such as carbon fiber composites, ceramic matrix composites, and certain polymer materials), the stability of the cooling circulating water is crucial to manufacturing quality. However, due to the formation of ice crystals in the water at low temperatures, the friction between ice crystals and sand particles generates electrostatic effects, causing sand particles to be electrostatically adsorbed and clogged in the filtration system, reducing water circulation efficiency and triggering additional maintenance requirements. Furthermore, the accumulation of static electricity can affect the accuracy of water conductivity measurements, thus interfering with the normal operation of water quality monitoring systems. To address these issues, existing technologies have integrated pulsed electric field antistatic modules into circulating water pipelines. These modules effectively reduce the electrostatic adsorption of ice crystals and sand particles and minimize interference with conductivity sensors.

[0027] Figure 1 This is a flowchart of the system according to an embodiment of the present invention. Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: The present invention provides, as follows Figure 1 The water circulation monitoring system for sand used in precision manufacturing, shown in the figure, includes an electrostatic accumulation module, an accumulation division module, an energy consumption difference module, and an iterative adjustment module.

[0030] The electrostatic accumulation module is used to acquire electrostatic accumulation data of cooling circulating water and sand particles in different cycles through high-precision sensors to calculate the electrostatic accumulation degree coefficient.

[0031] The cumulative partitioning module is used to calculate the power spectral density of the electrostatic accumulation degree coefficient through time series analysis, and to obtain the initial electrostatic accumulation threshold sequence based on the power spectral density of the electrostatic accumulation degree coefficient.

[0032] The energy consumption difference module is used to compare the electrostatic accumulation degree coefficient with the electrostatic accumulation threshold to allocate different pulse electric field intensities for different levels of electrostatic interference; and to calculate the energy consumption difference coefficient under different pulse electric field intensity strategies.

[0033] The iterative adjustment module is used to define the target optimization function of the electrostatic accumulation threshold and iteratively optimize the electrostatic accumulation threshold using the gradient descent method, continuously updating the electrostatic accumulation threshold.

[0034] The electrostatic accumulation module is used to acquire electrostatic accumulation data of cooling circulating water and sand particles in different cycles through high-precision sensors to calculate the electrostatic accumulation degree coefficient.

[0035] The electrostatic accumulation data includes sand concentration, ice crystal integral, water flow rate, and water temperature;

[0036] The electrostatic accumulation coefficient SEAC is calculated based on electrostatic accumulation data, and the expression is as follows: Where Qs represents sand concentration, Cice represents ice crystal integral, Vs represents water flow velocity, Ts represents water temperature, ∈r represents the dielectric constant of water, Ec represents the conductivity of water, f(Vs,Ts) represents the electrostatic cumulative effect factor of water flow velocity and water temperature, and f(Vs,Ts)=Vs*e Ts ;

[0037] It should be noted that the electrostatic accumulation data can be obtained through high-precision sensors and by setting a fixed acquisition period. The high-precision sensors include turbidity sensors, low-temperature ultrasonic attenuation sensors, electromagnetic flowmeters, platinum resistance temperature sensors, etc.

[0038] This invention uses high-precision sensors to monitor the electrostatic accumulation between cooling circulating water and sand particles, and calculates an electrostatic accumulation coefficient to measure the degree of electrostatic accumulation caused by friction and other factors in the cooling circulating water system. When the electrostatic accumulation coefficient is too high, it indicates severe electrostatic accumulation, which may affect conductivity readings and the stability of the filtration system. Through real-time monitoring of the electrostatic accumulation coefficient, the system can intelligently allocate pulse electric fields of different intensities to eliminate electrostatics, avoid unnecessary high-intensity pulse electric field operation, reduce energy waste, and improve system efficiency. By integrating multi-dimensional parameters such as sand particle concentration, ice crystal integral number, water flow rate, water temperature, dielectric constant, and conductivity, the physical nature of electrostatic adsorption risk is dynamically characterized. The complex electrostatic phenomenon is transformed into a real-time monitorable numerical signal, thereby providing a scientific basis for the precise control of the pulse electric field. The system intelligently identifies the periodicity of electrostatic interference and dynamically adjusts the intensity and duration of the pulse electric field accordingly, suppressing electrostatic adsorption and clogging while avoiding high-energy-consumption operation around the clock.

[0039] The cumulative partitioning module is used to calculate the power spectral density of the electrostatic accumulation degree coefficient through time series analysis, and to obtain the initial electrostatic accumulation threshold sequence based on the power spectral density of the electrostatic accumulation degree coefficient.

[0040] The time series of the electrostatic accumulation coefficient is obtained through the electrostatic accumulation module, and the power spectral density of the electrostatic accumulation coefficient is calculated using Fourier transform, as follows: P(f)=|∫SEAC(t)*e -j2πft dt| 2 In the formula, P(f) represents the power spectral density of the electrostatic accumulation coefficient, used to describe the energy distribution of the electrostatic accumulation coefficient at frequency f, SEAC(t) represents the electrostatic accumulation coefficient acquired at time t, and e -j2πft Let represent a complex exponential function, where e represents the base of the natural number, j represents the imaginary unit, π represents pi, f represents the frequency, and t represents time. The electrostatic interference period is obtained from the power spectral density, as follows: in This represents finding the value of f that maximizes the power spectral density function P(f), where T represents the electrostatic interference period. Wavelet transform is used to analyze the local perturbations of the electrostatic interference period, as detailed below: Where W(T,τ) represents the local characteristics of electrostatic interference, ψ * τ represents the complex conjugate of the wavelet basis function, and τ represents the time offset;

[0041] It should be noted that in this implementation, the Daubechies wavelet basis function is selected to perform wavelet transform on the electrostatic interference period.

[0042] The local electrostatic disturbance factor ΔJZ is calculated using the following expression: Where W(T,τ)k () represents the local characteristics of electrostatic interference at the k-th time offset, where k = {1, 2, 3, ..., K}, and K is a positive integer;

[0043] Calculate the electrostatic accumulation threshold: T1 i T2 represents the start time of the i-th electrostatic interference cycle. i YZ represents the end time of the i-th electrostatic interference cycle; i Let represent the electrostatic accumulation threshold for the i-th electrostatic interference cycle, where i = {1, 2, 3, ..., n}, and n is a positive integer;

[0045] This invention calculates the power spectral density of the electrostatic accumulation coefficient through time-series analysis and obtains an initial electrostatic accumulation threshold sequence based on this power spectral density, thus playing a crucial role in the entire monitoring system. First, Fourier transform analysis of the power spectral density of the electrostatic accumulation coefficient accurately extracts the periodic characteristics of electrostatic interference, ensuring the identification of interference frequencies in the system. This helps accurately determine the global characteristics of electrostatic interference and provides a solid foundation for subsequent threshold setting. Second, wavelet transform analysis of the local disturbances in the electrostatic interference period effectively captures short-term and transient electrostatic interference characteristics. This method, combining global frequency analysis with local time analysis using Fourier transform and local time analysis using wavelet transform, enables the system to perform more comprehensive and detailed monitoring and identification of electrostatic interference at different time scales. By calculating the local electrostatic disturbance factor, the impact of electrostatic interference is further refined, providing a more accurate basis for adjusting the electrostatic accumulation threshold under different interference scenarios.

[0046] The energy consumption difference module is used to compare the electrostatic accumulation degree coefficient with the electrostatic accumulation threshold to allocate different pulse electric field intensities for different levels of electrostatic interference; and to calculate the energy consumption difference coefficient under different pulse electric field intensity strategies.

[0047] In an optional example, the electrostatic accumulation level coefficient is compared with the electrostatic accumulation threshold to assign different pulse electric field intensities to different levels of electrostatic interference, as follows:

[0048] If SEAC ≤ YZ1, it indicates a slight electrostatic interference, which basically does not affect the water cycle, and a low-intensity pulsed electric field is adopted;

[0049] If YZ1 < SEAC ≤ YZ2, it indicates a medium electrostatic interference. To prevent the rapid accumulation of static electricity, a medium-intensity pulsed electric field is adopted;

[0050] If SEAC > YZ2, it indicates a strong electrostatic interference, and a high-intensity pulsed electric field is adopted to suppress the electrostatic interference;

[0051] Calculate the energy consumption difference coefficient under different pulsed electric field intensity strategies, as follows:

[0052] Calculate the pulsed electric field energy consumption. The expression is as follows: En = PW * Ty, where En represents the pulsed electric field energy consumption, PW represents the output power of the pulsed electric field, and Ty represents the duration of the pulsed electric field;

[0053] Calculate the energy consumption difference coefficient. The expression is as follows: Among them, PECC represents the energy consumption difference coefficient, Eba represents the pulsed electric field energy consumption when the pulsed electric field maintains the maximum output power all day long, and Edy represents the weighted sum of the pulsed electric field energy consumption under the actual pulsed electric field intensity strategy;

[0054] In the present invention, by comparing the electrostatic accumulation degree coefficient with the electrostatic accumulation threshold, different degrees of electrostatic interference are accurately identified and corresponding pulsed electric field intensities are intelligently allocated to ensure effective suppression of electrostatic interference while reducing unnecessary energy consumption. The energy consumption difference coefficient is used to measure the energy consumption optimization degree under different pulsed electric field intensity strategies. Its core role is to evaluate the energy-saving effect of the current pulsed electric field energy consumption relative to the all-day maximum power output, reflecting the dynamic regulation ability of the pulsed electric field energy consumption and the overall energy utilization efficiency. This coefficient can quantify the pulsed electric field energy consumption difference under different electrostatic interference degrees, ensure optimal energy consumption management strategies while effectively suppressing electrostatic accumulation, and improve the energy-saving performance and operation stability of the system;

[0055] The iterative adjustment module is used to define the electrostatic accumulation threshold target optimization function and perform iterative optimization of the electrostatic accumulation threshold using the gradient descent method, continuously updating the electrostatic accumulation threshold;

[0057] Perform iterative optimization of the electrostatic accumulation threshold using the gradient descent method: Among them, η is the learning rate, and J is the electrostatic accumulation threshold target optimization function. This represents the initial electrostatic accumulation threshold. This indicates the updated electrostatic accumulation threshold;

[0058] Gradient calculation:

[0059] This invention defines an objective optimization function for the electrostatic accumulation threshold and uses gradient descent to iteratively optimize the threshold. This allows the system to continuously update the electrostatic accumulation threshold under dynamic conditions, minimizing electrostatic accumulation error and optimizing energy management. By calculating the gradient of the objective function, the adjustment direction and step size of the electrostatic accumulation threshold are ensured to be reasonable, thereby avoiding local optima traps and accelerating convergence. During the iteration process, the threshold is dynamically optimized according to the real-time changes in electrostatic interference, enabling the system to adapt to different interference levels, optimize the pulse electric field control strategy, improve the electrostatic suppression effect of the water circulation system, and reduce unnecessary energy consumption, thereby improving the overall stability, energy efficiency, and economy of the system.

[0060] This invention integrates an electrostatic accumulation module, an accumulation division module, an energy consumption difference module, and an iterative adjustment module to achieve precise monitoring and intelligent optimization control of electrostatic interference in the cooling circulating water during the precision machining of low-temperature brittle materials, ensuring the stability and optimal energy efficiency of the water circulation system.
