Attached Figure Description

[0052] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, the drawings used in the description of the embodiments of this application or related technologies will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0053] Figure 1 This is a flowchart illustrating a method for detecting the components of a mixture in one embodiment;

[0054] Figure 2This is a schematic diagram of a mixture component detection device in one embodiment;

[0055] Figure 3 This is a flowchart illustrating a method for detecting the components of a mixture in another embodiment. Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] For example, such as Figure 1 As shown in the figure, this application provides a flowchart of a method for detecting components in a mixture, which may include the following steps:

[0058] Step S101: Determine the number of lasers and the wavelength of each laser based on the types of components contained in the mixture.

[0059] For example, in combination Figure 2 As shown, the device (or system) applying the above-described method for detecting the components of a mixture may include a laser emitter, a laser receiver, an analog-to-digital converter (ADC), and a microcontroller. The laser emitted by the laser emitter passes through the mixture and is received by the laser receiver. The ADC converts the laser signal collected by the laser receiver into an electrical signal, which is then transmitted to the microcontroller for further analysis and processing to obtain the component proportions of the mixture.

[0060] In this embodiment, after the laser passes through the liquid, some of its intensity is absorbed by the liquid, resulting in a decrease in the emitted light intensity. Different liquids have different abilities to absorb light intensity. The light intensity absorption capacity of a mixture composed of different liquids is the sum of the light intensity absorption capacities of each component in the mixture.

[0061] For example, if the mixture contains n types of components, then the number of lasers is determined to be n-1, where n is a natural number greater than 1; based on the n-1 components contained in the mixture, the wavelengths of the corresponding n-1 lasers are determined; wherein each wavelength is used to identify one component in the mixture.

[0062] In this embodiment, the mixture contains n types of components, and the detection target is the proportion of the n components in the mixture.

[0063] In step S102, each laser is controlled to emit laser light of the corresponding wavelength so that the laser light passes through the mixture.

[0064] Optionally, the laser can be a single or multiple independent lasers of a specific wavelength. The number of lasers is n-1. The selection criterion for the laser is: if a component of the mixture absorbs most of the light intensity of a laser of a certain wavelength, while other components of the mixture absorb almost no light intensity, then that wavelength of laser can be used to identify that component.

[0065] For example, the emission sequence of the lasers corresponding to each wavelength is determined; only one laser is turned on at a time to emit a laser of one wavelength, so that the laser of a single wavelength passes through the mixture. This allows different wavelengths of laser light to be controlled to irradiate the mixture separately, thus facilitating the subsequent acquisition of the laser signal after passing through the mixture by a laser receiver.

[0066] Step S103: Acquire the laser signal after passing through the mixture using a laser receiver.

[0067] In this embodiment, a specific combination of laser wavelengths can be selected to analyze a mixture of specific components. The components of the mixture exhibit significant differences in light intensity absorption across the different wavelengths included in the laser combination. By using a laser receiver to perform photo-to-electric conversion on the received laser signal, the non-voltage amplitude corresponding to the emitted laser intensity can be obtained, thereby acquiring different voltage amplitudes. Different wavelengths of laser light correspond to different voltage amplitudes, representing different substances. Based on this, the composition of the mixture can be analyzed.

[0068] Step S104: Perform photoelectric conversion processing on the laser signal collected by the laser receiver to obtain electrical signals corresponding to different wavelength laser signals.

[0069] For example, an analog-to-digital converter (ADC) performs photoelectric conversion processing on the laser signal acquired by the laser receiver to obtain the voltage amplitude corresponding to different wavelengths of laser signals; where different voltage amplitudes correspond to the proportions of different components in the mixture. The ADC can further convert analog signals (such as continuously changing signals like voltage and current) into digital signals.

[0070] Step S105: Analyze the component ratio of the mixture based on the electrical signal.

[0071] For example, the numerical value corresponding to the electrical signal is substituted into a pre-constructed objective function, and the component ratio corresponding to the electrical signal is calculated based on the objective function.

[0072] Optionally, before executing step S105, M samples of the mixture are first constructed; wherein, in the M samples of the mixture, the proportion of each component in each sample is known; M is a natural number greater than 1; if the mixture contains n types of components, then the number of lasers is determined to be n-1, where n is a natural number greater than 1; based on the n-1 components contained in the mixture, the wavelengths of the corresponding n-1 lasers are determined; the M samples are detected by the n-1 lasers respectively to obtain the electrical signals corresponding to the laser signals of different wavelengths; an initial fitting function is constructed, and the electrical signals corresponding to the laser signals of different wavelengths, as well as the known proportions of the mixture, are substituted into the initial fitting function to determine the coefficients of the initial fitting function, thus obtaining the target function.

[0073] For example, consider a mixture of benzene, ethanol, and isooctane. Ethanol has a strong absorption rate to 1550nm laser light. Benzene has a strong absorption rate to 1650nm laser light. Based on this characteristic, lasers with wavelengths of 1550nm and 1650nm can be selected to measure the ratio of ethanol and benzene in the mixture, and finally the ratio of isooctane can be determined.

[0074] Alternatively, the mixture composition detection process can be broadly divided into two stages: measurement and calibration. For details, please refer to [link to relevant documentation]. Figure 3 As shown. Wherein:

[0075] Step A, for measurement phase 1:

[0076] Step A1: Turn on the 1550nm laser and read the ADC reading, denoted as C1550-x. (x is a label indicating the proportion of a certain component)

[0077] Step A2: Turn off the 1550nm laser.

[0078] Step A3: Turn on the 1650nm laser to read the ADC reading, and record it as C1650-xx. (xx is a label indicating the ratio of two components)

[0079] Step A4: Turn off the 1650nm laser.

[0080] It should be understood that steps A3 and A4 above can also be performed before steps A1 and A2. The embodiments of this application do not limit the order in which different wavelength lasers are turned on.

[0081] Step B, for the calibration phase:

[0082] Step B1: Prepare 11 portions of a mixed solution of ethanol and isooctane, with volume ratios of ethanol:isooctane = 10:0, 9:1, 8:2, 7:3, 6:4, 5:5, 4:6, 3:7, 2:8, 1:9, and 0:10.

[0083] Step B2: Perform steps A1 to A2 of step A 11 times on each of the 11 solutions. Collect data as C. 1550-10 ~C 1550-0 .

[0084] Step B3, place C 1550-10 ~C 1550-0 These 11 data points were fitted using a second-order method:

[0085] y = ax 2 +bx+c Equation (1)

[0086] Where a, b, and c are coefficients, x is the proportion of ethanol, and y is the voltage ADC code value corresponding to the 1550nm laser.

[0087] Step B4: Find the inverse function of the function "y = ax² + bx + c" in step B3:

[0088]

[0089] Where a0, b0, c0, and d0 are coefficients, x is the proportion of ethanol, and y is the ADC reading of the voltage corresponding to the 1550nm laser.

[0090] Step B5: Prepare 66 aliquots of a mixed solution of ethanol, isooctane, and benzene, and divide them into 11 samples. The ethanol content in each sample remains constant, with ethanol percentages of 100%, 90%, ..., 0%. The volume proportions follow the guidelines in Table 1 below.

[0091] Table 1

[0092]

[0093]

[0094] Step B6 involves performing steps A1 to A4 (66 times in total) and step B3 on the above samples in 11 groups. The collected data is shown in Table 2.

[0095] Table 2

[0096]

[0097]

[0098] Step B7: Perform steps B3 to B4 on the data 1 to data 11 respectively to obtain the following relationship:

[0099]

[0100] The above 11 formulas represent the relationship between the voltage corresponding to the 1650nm laser and the benzene ratio when the ethanol ratio is 100%, 90%, ... 0%. Here, a1-a11, b1-b11, c1-c11, and d1-d11 are coefficients, x1-x11 is the benzene ratio, and y1-y11 is the ADC reading of the voltage corresponding to the 1650nm laser.

[0101] Step C, for measurement phase 2:

[0102] Step C1: Perform steps A1 to A4 to obtain data C. 1550 C 1650 .

[0103] Step C2, C 1550 Substituting y into equation (2), we can calculate x, which is the ethanol ratio.

[0104] Step C3: Select the ethanol from equations (3) to (13) that match the ethanol ratio, and then add C... 1650 Substituting y into the formula, we can calculate x, which is the benzene ratio.

[0105] Step C4, isooctane ratio = 100% - ethanol ratio - benzene ratio.

[0106] In this embodiment, a miniaturized laser is used, significantly reducing the size of the equipment. By selecting multiple laser sources with specific wavelengths for detecting specific mixtures, all lasers can be used, reducing operating costs.

[0107] It should be understood that the embodiments of this application do not limit the number of lasers used. For example, the number of lasers used can be determined based on the proportion of unknown components and the proportion of known components in the mixture.

[0108] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
