Description

Technical Field

[0001] The present invention relates to the technical field of filter element detection, and in particular to a silver-based composite filter element detection method and system. Background Art

[0002] The car air conditioning filter is an important component installed in the vehicle air conditioning system. It is mainly used to filter and purify the air entering the car. It can effectively remove harmful substances such as particulate matter, dust, pollen, bacteria, viruses, odors, etc. in the air, providing a cleaner and healthier air environment in the car. At present, the car air conditioning filter mainly uses silver-based fibers to achieve the filtering and purification effect. Silver-based fibers refer to fibers made of 99.99% pure silver and polymer silver-based fibers using high-tech antibacterial technology, which can kill or hinder the growth and reproduction of bacteria and reduce their number and activity.

[0003] The reason why silver-based fibers are antibacterial is because pure silver plays a role. The antibacterial principle of pure silver is that at the molecular level, the presence of catalysts (such as water or heat) activates the activity of silver and releases silver ions. The silver ions bind to receptors on the cell wall to prevent cell respiration, damage bacterial DNA and prevent its replication.

[0004] Therefore, the filtering effect of the air conditioning filter can be detected by detecting the silver content in the silver-based fiber. The current method for detecting the silver content in the silver-based fiber is mainly through atomic absorption spectroscopy, that is, the silver atoms in the sample silver-based fiber absorb light of a specific wavelength, and the silver content is determined by the degree of light absorption. However, the above method requires the silver-based fiber to absorb sufficient light, and the detection and analysis time is too long, and the silver content in the silver-based fiber cannot be known in real time, and thus the filtering effect of the air conditioning filter cannot be detected in real time.

[0088] As described in the above steps S1-S9, the vehicle air conditioning filter is an important component installed in the vehicle air conditioning system. At present, the vehicle air conditioning filter mainly uses silver-based fibers to achieve the filtering and purification effect. Silver-based fibers refer to fibers that are prepared by high-tech antibacterial technology using 99.99% pure silver and polymer silver-based fibers, which have the function of killing or hindering the growth and reproduction of bacteria and reducing their number and activity. The reason why silver-based fibers are antibacterial is that pure silver plays a role. The antibacterial principle of pure silver is that at the molecular level, the presence of catalysts (such as water or heat) activates the activity of silver and releases silver ions. Ions will bind to receptors on the cell wall to prevent cell respiration, and destroy bacterial DNA to prevent its replication. Therefore, the filtering effect of the air conditioning filter can be detected by detecting the silver content in silver-based fibers. The current method of detecting the silver content in silver-based fibers is mainly through atomic absorption spectroscopy, that is, the silver atoms in the sample silver-based fibers absorb light of a specific wavelength, and the silver content is determined by the degree of light absorption. However, the above method requires the silver-based fibers to absorb sufficient light, and the detection and analysis time is too long. It is impossible to know the silver content in the silver-based fibers in real time, and thus it is impossible to detect the filtering effect of the air conditioning filter in real time. The present invention obtains the initial external magnetic field strength and the external magnetic field strength table of the air conditioning filter system, obtains the initial magnetic induction intensity value of the silver-based fiber according to the initial external magnetic field strength, applies an external magnetic field to the silver-based fiber according to the external magnetic field strength table to obtain different first magnetic induction intensity values ​​corresponding to different magnetic field pressure values, and simultaneously reduces the external magnetic field to the silver-based fiber according to the external magnetic field strength table to obtain different second magnetic induction intensity values ​​corresponding to different magnetic field pressure values, and draws a magnetization curve according to the initial magnetic induction intensity value, a plurality of first magnetic induction intensity values, and the second magnetic induction intensity value. Since the magnetization curve analysis is a non-destructive testing method, it is not necessary to destroy the sample or physically treat it, which makes the detection process more convenient and reliable. Through the magnetization curve analysis, the magnetic data of the silver-based fiber can be quickly obtained, including the initial magnetic induction intensity and the response conditions under different external magnetic fields. These data can be used to It can be used to evaluate the quality and characteristics of silver-based fibers immediately without waiting for the results of traditional chemical analysis like atomic absorption spectrometry. The magnetization curve can provide magnetic response data of silver-based fibers under different external magnetic field strengths. By analyzing the slope of the curve, the magnetization characteristics of the silver-based fibers can be quantified, thereby inferring the amount of silver content. The external magnetic permeability of the silver-based fibers is calculated according to multiple second magnetic induction intensity values ​​and the first magnetic induction intensity values, wherein the external magnetic permeability refers to the relative response ability of the silver-based fibers in an external magnetic field, that is, the degree of magnetization under the action of an external magnetic field. Compared with traditional chemical analysis methods such as atomic absorption spectrometry, the calculation of the external magnetic permeability can usually be completed more quickly, and the calculation of the external magnetic permeability has good reliability, making the evaluation of the silver content of the silver-based fibers more accurate. Multiple saturation magnetization intensities and residual magnetization intensities of the silver-based fibers are obtained according to the magnetization curve.The magnetic susceptibility of the silver-based fiber is obtained according to the magnetization curve, wherein the magnetic susceptibility refers to the degree of magnetization generated by the silver-based fiber under the action of an external magnetic field. Since the silver content in the silver-based fiber usually affects its magnetic properties, such as saturation magnetization and residual magnetization, the quantitative data of these magnetic characteristics can be directly obtained by measuring and analyzing the magnetization curve. The magnetic susceptibility reflects the responsiveness of the silver-based fiber to the external magnetic field. An increase in the silver content in the silver-based fiber usually leads to a change in its magnetic susceptibility. Therefore, the relative amount of silver content can be indirectly inferred by calculating the magnetic susceptibility. The silver content is calculated based on the magnetic susceptibility, the applied magnetic permeability, the residual magnetization and multiple saturation magnetizations, wherein the residual magnetization refers to the magnetization still exhibited by the silver-based fiber after the external magnetic field is removed, and the saturation magnetization refers to the magnetization at a higher The maximum magnetization intensity of silver-based fibers under an applied magnetic field, magnetic susceptibility, applied magnetic permeability, saturation magnetization and residual magnetization can be directly used to quantitatively analyze the silver content in silver-based fibers. These parameters are closely related to the magnetic response and magnetic properties of silver. The silver content can be detected through measurement and analysis. Compared with traditional chemical analysis methods such as atomic absorption spectroscopy, the use of magnetic parameters to evaluate silver content is usually faster and more efficient. Since parameters such as magnetic susceptibility, applied magnetic permeability and magnetization have high reliability, this ensures that the results of silver content analysis are stable and accurate. The analysis of the magnetization curve can provide the precise content of silver in the silver-based fibers. The silver content can be calculated in more detail and accurately through parameter characteristics such as residual magnetization and multiple saturation magnetization. ,

[0089] In one embodiment, the step S5 of calculating the applied magnetic permeability of the silver-based fiber according to the plurality of the second magnetic induction intensity values ​​and the first magnetic induction intensity values ​​comprises:

[0090] S51, acquiring a corresponding first external magnetic field pressure value according to each first magnetic induction intensity value;

[0093] S54, calculating the external magnetic permeability of the silver-based fiber according to the vacuum magnetic permeability, multiple first magnetic induction intensity values, the first external magnetic field pressure value, the second magnetic induction intensity value, and the second external magnetic field pressure value, wherein the calculation formula is:

[0094]

[0095] Where W(C) represents the external magnetic permeability, C(1) n Indicates the nth first magnetic induction intensity value, W(1) nrepresents the first external magnetic field pressure value corresponding to the nth first magnetic induction intensity value, C(2) m represents the mth second magnetic induction intensity value, W(2) m represents the second external magnetic field pressure value corresponding to the mth second magnetic induction intensity value, a represents the vacuum magnetic permeability, N represents the total number of first magnetic induction intensity values, M represents the total number of second magnetic induction intensity values, n represents the serial number of the first magnetic induction intensity value, and m represents the serial number of the second magnetic induction intensity value.

[0096] As described in the above steps S51-S54, the present invention obtains the corresponding first external magnetic field pressure value and second external magnetic field pressure value through each first magnetic induction intensity value and the second magnetic induction intensity value, and then obtains the vacuum magnetic permeability of the silver-based fiber under vacuum, and calculates the external magnetic permeability of the silver-based fiber according to the vacuum magnetic permeability, multiple first magnetic induction intensity values, first external magnetic field pressure values, second magnetic induction intensity value and second external magnetic field pressure value. Since the external magnetic permeability is calculated by accurately measuring the magnetization response of the silver-based fiber under different magnetic field intensities, it is faster than traditional chemical analysis methods such as atomic absorption spectrometry. The multiple first magnetic induction intensity values ​​obtained by applying an external magnetic field to the silver-based fiber and the multiple second magnetic induction intensity values ​​obtained by reducing the external magnetic field to the silver-based fiber are combined with the external magnetic permeability calculated by vacuum magnetic permeability, so as to facilitate the calculation of the silver content in the silver-based fiber, so that the detection result is more accurate. The external magnetic permeability can provide a comprehensive magnetic property analysis of the silver-based fiber by combining the magnetic induction intensity values ​​and external magnetic field pressure values ​​under different conditions. These data reflect the magnetic response behavior of the silver-based fiber under different magnetic field conditions.

[0097] In one embodiment, the step S6 of drawing a magnetization curve according to the initial magnetic induction intensity value, the plurality of first magnetic induction intensity values ​​and the second magnetic induction intensity value comprises:

[0101] S64, taking each first magnetic field pressure value and the corresponding first magnetic induction intensity value as a first connection point, and plotting the starting coordinate point and the plurality of first connection points on the magnetic field intensity-magnetic induction axis through a curve to obtain a preliminary curve;

[0102] S65, taking each second magnetic field pressure value and the corresponding second magnetic induction intensity value as a second connection point;

[0103] S66. The end point of the preliminary curve and a plurality of second connection points are plotted on the magnetic field intensity-magnetic induction axis through a curve to obtain a magnetization curve.

[0104] As described in the above steps S61-S66, in the present invention, the corresponding initial external magnetic field intensity, multiple first magnetic field pressure values ​​and second magnetic field pressure values ​​are respectively obtained through the initial magnetic induction intensity value, multiple first magnetic induction intensity values ​​and the second magnetic induction intensity value, and the magnetic field intensity-magnetic induction axis is established with the external magnetic field intensity as the X-axis and the magnetic induction intensity value as the Y-axis, and then the initial external magnetic field intensity and the initial magnetic induction intensity value are used as the starting coordinate points, each first magnetic field pressure value and the corresponding first magnetic induction intensity value are used as the first connection point, and the starting coordinate point and the multiple first connection points are plotted on the magnetic field intensity-magnetic induction axis through a curve to obtain a preliminary curve, and each second magnetic field pressure value is plotted on the magnetic field intensity-magnetic induction axis through a curve. The force value and the corresponding second magnetic induction intensity value are used as the second connection point, and the end point of the preliminary curve and multiple second connection points are plotted on the magnetic field intensity-magnetic induction axis through a curve to obtain a magnetization curve. In this way, by taking the external magnetic field intensity as the X-axis and the magnetic induction intensity as the Y-axis, the magnetization curve can intuitively display the magnetic response of the silver-based fiber under different external magnetic field conditions. By plotting the magnetization curve, the change of the magnetic induction intensity of the silver-based fiber when the external magnetic field is applied and reduced can be analyzed. According to the magnetization curve, the magnetic parameters of the silver-based fiber, such as saturation magnetic induction intensity, residual magnetic induction intensity, magnetic permeability, etc., can be quantified, thereby facilitating the detection and calculation of the silver content in the silver-based fiber.

[0105] In one embodiment, the step S7 of obtaining a plurality of saturation magnetization intensities and residual magnetization intensities of the silver-based fiber according to the magnetization curve comprises:

[0106] S71, obtaining multiple peak values ​​of the magnetization curve within a preset interval, and taking each peak value as a saturation magnetization intensity to obtain multiple saturation magnetization intensities;

[0108] S73, calculating the residual magnetization intensity according to the third magnetic induction intensity value and a plurality of fourth magnetic induction intensity values, wherein the calculation formula is:

[0109]

[0110] Where, S(C) represents the residual magnetization, W(3) represents the third magnetic induction value, and W(4)i represents the i-th fourth magnetic induction intensity value, E represents the number of fourth magnetic induction intensity values, and i represents the sequence number of the fourth magnetic induction intensity value.

[0111] As described in the above steps S71-S73, the present invention obtains multiple peak values ​​of the magnetization curve within a preset interval, and uses each peak value as the saturation magnetization to obtain multiple saturation magnetization intensities, then obtains the third magnetic induction intensity value of the silver-based fiber when the magnetization curve reduces the last second magnetic field pressure value, and continuously monitors and obtains multiple fourth magnetic induction intensity values ​​of the silver-based fiber within a preset time, and calculates the residual magnetization intensity according to the third magnetic induction intensity value and the multiple fourth magnetic induction intensity values. In this way, by identifying multiple peak values ​​in the magnetization curve and considering them as the saturation magnetization intensity of the silver-based fiber, accurate quantification of the maximum magnetic response of the silver-based fiber under different magnetic field intensities can be provided, and the residual magnetization intensity of the silver-based fiber can be calculated using the third magnetic induction intensity value and the multiple fourth magnetic induction intensity values. The residual magnetization intensity refers to the magnetic induction intensity that the silver-based fiber still retains after the external magnetic field is removed. By continuously monitoring the fourth magnetic induction intensity value within the preset time, the magnetic response data of the silver-based fiber at different time points can be obtained in real time. This real-time data acquisition is helpful for analyzing the dynamic magnetization characteristics of the silver-based fiber. By obtaining the saturation magnetization intensity and residual magnetization intensity in the magnetization curve, and continuously monitoring the magnetic induction intensity at multiple time points, the magnetic characteristics of the silver-based fiber can be fully understood. The peak value in the magnetization curve reflects the saturation magnetization intensity of the silver-based fiber under different magnetic fields. These data have high certainty and reliability, thereby improving the accuracy of the silver content calculation. By obtaining the peak value and residual magnetization intensity data in the magnetization curve, the silver content in the silver-based fiber can be easily detected and calculated.

[0112] In one embodiment, the step S8 of obtaining the magnetic susceptibility of the silver-based fiber according to the magnetization curve comprises:

[0113] S81, obtaining a plurality of first magnetic induction intensity values ​​and a plurality of corresponding first magnetic field pressure values ​​on the magnetization curve;

[0114] S82, calculating a first slope according to a plurality of first magnetic induction intensity values ​​and a first magnetic field pressure value;

[0115] S83, obtaining a plurality of second magnetic induction intensity values ​​and a plurality of corresponding second magnetic field pressure values ​​on the magnetization curve;

[0116] S84, calculating a second slope according to the plurality of second magnetic induction intensity values ​​and the second magnetic field pressure values, wherein the calculation formula is:

[0117]

[0118] Where D(X) represents the second slope, C(2)m represents the mth second magnetic induction intensity value, Q(2) m represents the mth second magnetic field pressure value, M represents the number of second magnetic induction intensity values, and m represents the sequence number of the second magnetic induction intensity value;

[0119] S85. Obtain the magnetic susceptibility of the silver-based fiber according to the average value of the second slope and the first slope.

[0120] As described in the above steps S81-S85, the present invention obtains a plurality of first magnetic induction intensity values ​​and a plurality of corresponding first magnetic field pressure values ​​and a plurality of second magnetic induction intensity values ​​and a plurality of corresponding second magnetic field pressure values ​​on the magnetization curve, calculates a first slope according to the plurality of first magnetic induction intensity values ​​and the first magnetic field pressure values, calculates a second slope according to the plurality of second magnetic induction intensity values ​​and the second magnetic field pressure values, and obtains the magnetic susceptibility of the silver-based fiber according to the average value of the second slope and the first slope. The first slope and the second slope reflect the rate of change of the magnetic response of the silver-based fiber under different external magnetic field intensities. These slopes can be used to understand the magnetic field sensitivity and saturation magnetization behavior of the silver-based fiber. By calculating the slopes, the magnetic susceptibility of the silver-based fiber under different magnetic field conditions can be quantified. The magnetic susceptibility is an important parameter that describes the magnetization ability of silver-based fibers under an external magnetic field. The magnetic susceptibility obtained by calculating the average of the first slope and the second slope can provide a quantitative measure of the magnetic properties of the silver-based fibers. This magnetic susceptibility directly reflects the influence of the silver content in the silver-based fibers on the magnetic field response, and is an important indicator for measuring the magnetic strength of the silver-based fibers. The averaged magnetic susceptibility can be used to calculate the change in the silver content in the silver-based fibers. Compared with traditional chemical analysis methods, this physical measurement method is not only faster, but also has more accurate calculation results. The method for calculating the first slope based on multiple first magnetic induction intensity values ​​and first magnetic field pressure values ​​is the same as the method for calculating the second slope.

[0121] In one embodiment, the step S9 of calculating the silver content according to the magnetic susceptibility, the applied magnetic permeability, the residual magnetization and the plurality of saturation magnetizations comprises:

[0122] Extracting the maximum value among multiple saturation magnetization intensities to obtain the maximum magnetization intensity;

[0123] The magnetization intensity ratio is calculated according to the maximum magnetization intensity and the residual magnetization intensity, wherein the calculation formula is:

[0125] Among them, C(B) represents the magnetization ratio, Z(C) represents the maximum magnetization, and S(C) represents the residual magnetization;

[0126] Obtain the density of silver-based fibers and the molar mass of silver;

[0130] As described in the above steps S91-S9, the present invention obtains the maximum magnetization intensity by extracting the maximum value of multiple saturation magnetization intensities, calculates the magnetization intensity ratio according to the maximum magnetization intensity and the residual magnetization intensity, and then calculates the silver content according to the density of the silver-based fiber, the molar mass of silver, the magnetic susceptibility, the external magnetic permeability, the magnetization intensity ratio, the residual magnetization intensity and multiple saturation magnetization intensities. By calculating the magnetization intensity ratio, the relationship between the silver content in the silver-based fiber and its magnetic properties can be evaluated. The maximum magnetization intensity reflects the maximum magnetization ability of the silver-based fiber under a magnetic field. By comparing the maximum magnetization intensity with the residual magnetization intensity, the silver content can be calculated. The ratio of magnetization intensity can evaluate the magnetic saturation degree of silver-based fibers. The maximum magnetization intensity and the residual magnetization intensity are related to the silver content in the silver-based fibers, which provides an important basis for the accurate calculation of the silver content in the silver-based fibers. By real-time monitoring the relationship between magnetic parameters and silver content, and using multiple parameters such as the density of silver-based fibers, molar mass of silver, magnetic susceptibility, applied magnetic permeability, magnetization intensity ratio, residual magnetization intensity and saturation magnetization intensity, a composite model can be established to accurately calculate the silver content.
