Description

Technical Field

[0001] The present application relates to the field of impurity detection, and in particular to an impurity monitoring method, device, equipment and medium based on ultraviolet fluorescence. Background Art

[0002] The ultraviolet fluorescence method excites the molecules in the sample through ultraviolet light, putting them in an excited state, and then returns to the ground state through fluorescence radiation transition and emits fluorescence. Quantitative or qualitative information about the substance can be obtained based on the measurement of fluorescence intensity and characteristic wavelength.

[0003] The general steps for detection by ultraviolet fluorescence are: collect the liquid sample to be tested, and perform necessary pretreatment, such as filtration, dilution, etc., to remove interfering substances and adjust the sample concentration to an appropriate range. Select a suitable ultraviolet fluorescence detector, and set the excitation wavelength and detection wavelength according to the characteristics of the impurities to be tested. The excitation wavelength should be able to effectively excite the impurity molecules to produce fluorescence, and the detection wavelength should be able to accurately capture and measure the fluorescence signal.

[0004] Currently, the method of detecting impurities in liquids using ultraviolet fluorescence technology generally relies on statically set light sources and detection devices. Since the light source and the detection unit are fixed in specific positions, it is difficult to flexibly respond to the uneven distribution or dynamic changes of impurities in liquid samples, resulting in significant uncertainty in the detection results, which in turn affects the accuracy of the detection data. Summary of the invention

[0005] In order to improve the accuracy of detecting impurities in liquid, the present application provides an impurity monitoring method, device, equipment and medium based on ultraviolet fluorescence.

[0006] In a first aspect, the present application provides an impurity monitoring method based on ultraviolet fluorescence, which adopts the following technical solution: An impurity monitoring method based on ultraviolet fluorescence, comprising: Obtain the liquid category of the liquid to be detected; Based on the liquid category corresponding to the liquid to be detected, determining at least two sets of ultraviolet data corresponding to the liquid to be detected; Generate a detection instruction corresponding to each set of ultraviolet data, and send the detection instruction to the light-emitting module, wherein the detection instruction includes the light-emitting time and the rotation angle of the light-emitting module; Receive the test results corresponding to each set of test instructions, and determine whether the test results meet the result requirements based on the test results; If the detection result meets the result requirement, the detection result is used as the impurity detection result of the liquid to be detected.

[0007] By adopting the above technical solution, a high degree of flexibility is demonstrated by obtaining the liquid category of the liquid to be detected and determining at least two sets of ultraviolet data for detection based on the category. Different liquids may have different absorption characteristics of ultraviolet light, so customizing the detection scheme for specific liquid categories can more accurately reflect the impurities in the liquid. In addition, the light-emitting module is designed to be rotatable, and the light-emitting angle can be adjusted according to the detection requirements, and the liquid can be tested multiple times, multiple sets of test results can be received and comprehensively judged, which can further improve the accuracy of impurity detection and reduce the possibility of false alarms and missed reports. At the same time, the entire process from sample preparation to result output can be completed without human intervention, reducing the time cost and error risk caused by human operation.

[0008] In a possible implementation, the ultraviolet data includes ultraviolet light wavelength, and determining at least two sets of ultraviolet data corresponding to the liquid to be detected based on the liquid category corresponding to the liquid to be detected includes: Acquire each impurity type corresponding to the liquid type, and determine the absorbable wavelength range corresponding to each impurity type; Based on the absorbable wavelength range, at least two ultraviolet wavelengths corresponding to the liquid to be detected are determined to obtain at least two groups of ultraviolet data corresponding to the liquid to be detected.

[0009] By adopting the above technical solution, by obtaining the types of impurities corresponding to the liquid type and determining their respective absorbable wavelength ranges, the wavelength of ultraviolet light can be selected for detection in a very targeted manner. Different impurities have different absorption characteristics of ultraviolet light and have specific absorption wavelengths or wavelength ranges. Therefore, selecting an ultraviolet light wavelength that matches the absorption characteristics of the target impurity for detection can greatly improve the pertinence and accuracy of the detection and reduce false detection or missed detection of other non-target impurities. Determining at least two ultraviolet light wavelengths for detection based on the absorbable wavelength range means that information from multiple dimensions is taken into account during the detection process, which helps to more comprehensively cover the types of impurities that may exist in the liquid and improve the accuracy of the detection. At the same time, by comparing the test results at different wavelengths, the presence and type of impurities can be further verified and confirmed.

[0010] In a possible implementation, the generating of the detection instruction corresponding to each set of ultraviolet data includes: Acquire the container circumference of the container corresponding to the liquid to be detected and the rotation speed of the light emitting module; Determining the number of detections and the detection angle based on the length and width of the container; Determine the rotation angle corresponding to each detection angle; Determining a light-emitting time of the light-emitting module based on a rotation speed and a rotation angle of the light-emitting module; Based on the light-emitting time and the rotation angle of the light-emitting module, a detection instruction corresponding to each set of ultraviolet data is generated.

[0011] By adopting the above technical solution, by determining the number of detections and the detection angle based on the circumference of the container, it is possible to ensure that the liquid in the entire container is fully and completely detected, and impurities caused by blind detection areas can be effectively avoided, thereby improving the accuracy and comprehensiveness of the detection. The rotation angle corresponding to each detection angle is further determined, and the light-emitting moment is accurately calculated based on the rotation speed and rotation angle, so that the light-emitting module can emit ultraviolet light at the most appropriate time and position to excite impurities that may exist in the liquid and generate detectable fluorescent signals, which helps to capture weaker fluorescent signals and further improve the detection accuracy.

[0012] In a possible implementation, determining the rotation angle corresponding to each detection angle includes: Acquire the current state of the light-emitting module and the relative position of the light-emitting module and the container of the liquid to be detected; Establishing a three-dimensional coordinate system based on the relative position of the light-emitting module and the container of the liquid to be detected; Based on the current state of the light-emitting module, determine the corresponding three-dimensional coordinates of each vertex of the light-emitting module; Determining a current angle between the light emitting module and a container of the liquid to be detected; Based on each of the detected angles and the current angle, a rotation angle corresponding to each detected angle is determined.

[0013] By adopting the above technical solution, by obtaining the current shape of the light-emitting module and its relative position to the liquid container to be detected, and establishing a three-dimensional coordinate system on this basis, the position of each vertex of the light-emitting module in the three-dimensional space can be accurately determined, so that when the rotation angle corresponding to each detection angle is subsequently calculated, the actual shape and position of the light-emitting module can be taken into account, thereby avoiding errors introduced by simplified models or approximate calculations. Furthermore, the accuracy of the rotation angle is ensured, so that the light-emitting module can accurately point to each predetermined detection angle, improving the accuracy and pertinence of the detection. Not only the relative position of the light-emitting module and the container is taken into account, but also the current shape of the light-emitting module is taken into account, which enables it to accurately calculate the rotation angle in complex environments or containers, such as irregularly shaped containers or in the presence of obstructions, and has the characteristics of strong adaptability, while also improving the robustness and practicality of the detection system.

[0014] In a possible implementation, determining the light-emitting time of the light-emitting module based on the rotation speed and the rotation angle of the light-emitting module includes: Based on the current angle and each detected angle, determining an angle to be rotated from the current angle to each detected angle; Based on the rotation speed and the angle to be rotated, determining a rotation duration corresponding to each rotation angle; The arrival time corresponding to each rotation duration is determined as the light-emitting time corresponding to the light-emitting module.

[0015] By adopting the above technical solution, by calculating the angle to be rotated from the current angle to each detection angle, and combining the rotation speed to determine the rotation time corresponding to each rotation angle, and then determining the light-emitting time of the light-emitting module, it is ensured that the light-emitting module emits ultraviolet light at the correct position and time point, which helps to reduce the detection error caused by inaccurate light-emitting timing and improves the accuracy and reliability of detection. When performing continuous detection at multiple detection angles, precise light-emitting time control can also effectively avoid the overlap and interference of fluorescent signals between different detection angles. Each detection angle is excited at its specific light-emitting time, thereby ensuring the independence and accuracy of each detection result.

[0016] In a possible implementation, the detection result includes a fluorescence intensity and a characteristic wavelength, and the receiving the detection result corresponding to each group of detection instructions and determining whether the detection result meets the result requirement based on the detection result includes: Obtaining the fluorescence intensity range and characteristic wavelength range corresponding to the liquid type; Determining a first confidence level corresponding to the fluorescence intensity range and a second confidence level corresponding to the characteristic wavelength range; Determining a fluorescence intensity requirement based on the first confidence level and the fluorescence intensity range, and determining a characteristic wavelength requirement based on the characteristic wavelength range and the second confidence level; Determine whether the fluorescence intensity meets the fluorescence intensity requirement, and determine whether the characteristic wavelength meets the characteristic wavelength requirement, so as to determine whether the detection result meets the result requirement.

[0017] By adopting the above technical solution, not only the key indicator of fluorescence intensity is taken into account, but also the characteristic wavelength is introduced as an evaluation criterion. Fluorescence intensity and characteristic wavelength are two responses of different properties produced by a substance under ultraviolet light irradiation, which together reflect the characteristics and state of the substance. By evaluating these two indicators at the same time, the properties of the liquid to be tested can be more comprehensively understood, thereby improving the accuracy of the detection. When determining the requirements for fluorescence intensity and characteristic wavelength, the corresponding confidence level is also considered. The confidence level reflects the reliability and credibility of the evaluation results. By introducing the concept of confidence level, the test results can be evaluated more finely and scientifically, reducing the possibility of misjudgment and missed judgment, and further improving the reliability of the detection.

[0018] In a possible implementation, when the detection result does not meet the result requirement, the method further includes: Determining infrared data corresponding to the liquid to be detected, wherein the infrared data includes infrared light wavelength; Controlling the light emitting module to emit infrared light of the infrared light wavelength; receiving an infrared detection result corresponding to the infrared light; Based on the infrared detection result and the detection result corresponding to each group of detection instructions, the impurity detection result of the liquid to be detected is determined.

[0019] By adopting the above technical solution, when the UV detection results do not meet the requirements, the infrared data is introduced for supplementary detection, thus achieving comprehensive analysis of multi-spectrum. Since UV and infrared light have different physical properties and penetration capabilities, they can reveal the absorption, reflection or emission characteristics of substances at different wavelengths. Therefore, by combining the UV and infrared detection results, the composition and properties of the liquid to be detected can be more fully understood, and the accuracy of detection can be improved.

[0020] In a second aspect, the present application provides an impurity monitoring device based on ultraviolet fluorescence, which adopts the following technical solution: An impurity monitoring device based on ultraviolet fluorescence, comprising: An acquisition module, used for acquiring the liquid category of the liquid to be detected; A determination module, used for determining at least two sets of ultraviolet data corresponding to the liquid to be detected based on the liquid category corresponding to the liquid to be detected; A generating module, used for generating a detection instruction corresponding to each set of ultraviolet data, and sending the detection instruction to the light-emitting module, wherein the detection instruction includes the light-emitting time and the rotation duration of the light-emitting module; A receiving module, used to receive the test results corresponding to each group of test instructions, and determine whether the test results meet the result requirements based on the test results; As a module, if the detection result meets the result requirement, then the detection result is used as the impurity detection result of the liquid to be detected.

[0021] In a possible implementation, when the determination module determines at least two sets of ultraviolet data corresponding to the liquid to be detected based on the liquid category corresponding to the liquid to be detected, it is specifically used to: Acquire each impurity type corresponding to the liquid type, and determine the absorbable wavelength range corresponding to each impurity type; Based on the absorbable wavelength range, at least two ultraviolet wavelengths corresponding to the liquid to be detected are determined to obtain at least two groups of ultraviolet data corresponding to the liquid to be detected.

[0022] In a third aspect, the present application provides an electronic device, which adopts the following technical solution: An electronic device, comprising: at least one processor; Memory; At least one application, wherein the at least one application is stored in a memory and configured to be executed by at least one processor, and the at least one application is configured to: execute the impurity monitoring method based on ultraviolet fluorescence described in the first aspect above.

[0023] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium includes: a computer program that can be loaded by a processor and execute the impurity monitoring method based on ultraviolet fluorescence described in the first aspect.

[0024] In summary, this application includes the following beneficial technical effects: By obtaining the liquid category of the liquid to be tested and determining at least two sets of UV data for testing based on the category, a high degree of flexibility is demonstrated. Different liquids may have different absorption characteristics of ultraviolet light, so customizing the detection plan for specific liquid categories can more accurately reflect the impurities in the liquid. In addition, the light-emitting module is designed to be rotatable, and the light-emitting angle can be adjusted according to the detection requirements, and the liquid can be tested multiple times, multiple sets of test results can be received and comprehensively judged, which can further improve the accuracy of impurity detection and reduce the possibility of false alarms and missed alarms. At the same time, the entire process from sample preparation to result output can be completed without human intervention, reducing the time cost and error risk caused by human operation.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The ultraviolet fluorescence method excites the molecules in the sample through ultraviolet light, making them in an excited state, and then returns to the ground state through the radiation transition of fluorescence and emits fluorescence. According to the measurement of fluorescence intensity and characteristic wavelength, quantitative or qualitative information of the substance can be obtained. The general steps for detection by ultraviolet fluorescence method are: collect the liquid sample to be detected, and perform necessary pretreatment, such as filtration, dilution, etc., to remove interfering substances and adjust the sample concentration to an appropriate range. Select a suitable ultraviolet fluorescence detector, and set the excitation wavelength and detection wavelength according to the characteristics of the impurities to be detected. The selection of the excitation wavelength should be able to effectively excite the impurity molecules to produce fluorescence, and the detection wavelength should be able to accurately capture and measure the fluorescence signal. At present, the method of detecting impurities in liquids using ultraviolet fluorescence technology generally relies on statically set light sources and detection devices. Since the light source and the detection unit are fixed in a specific position, it is difficult to flexibly respond to the uneven distribution or dynamic changes of impurities in the liquid sample, resulting in the uncertainty of the test results that cannot be ignored, which in turn affects the accuracy of the test data.

[0029] In view of this, the present application embodiment provides an impurity monitoring method based on ultraviolet fluorescence, see Figure 1 In the figure, the impurity monitoring device 10 includes a light-emitting module 101 and a detection module 102. The impurity monitoring module is connected to the electronic device. The light-emitting module 101 is a rotatable module. The electronic device can control the rotation of the light-emitting module 101, and can also control the light-emitting module 101 to emit light. At the same time, the electronic device can control the detection module 102 to detect the fluorescence generated by the liquid to be detected, and receive the detection results sent by the detection module.

[0030] The present application embodiment provides an impurity monitoring method based on ultraviolet fluorescence, such as Figure 2As shown, the method provided in the embodiment of the present application is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S201 to S205, wherein: Step S201, obtaining the liquid type of the liquid to be detected.

[0031] Among them, the liquid types include drinking water, industrial wastewater, cosmetic solutions, etc. Since different liquid types may contain different impurities, the liquid type corresponding to the liquid to be detected can be obtained. Specifically, when the staff puts the liquid to be detected on the impurity detection device, they will input the number of the liquid to be detected, and the electronic device receives the number of the liquid to be detected and obtains the liquid type corresponding to the number.

[0032] Step S202: based on the liquid category corresponding to the liquid to be detected, determine at least two sets of ultraviolet data corresponding to the liquid to be detected.

[0033] Among them, each liquid to be detected corresponds to a number, each number corresponds to a liquid information, and the liquid information includes the liquid category and at least two impurity types. A first database is established based on the number of each liquid to be detected and the liquid information corresponding to each number, and a second database is established based on the ultraviolet detection wavelength corresponding to each impurity type.

[0034] The ultraviolet data includes the ultraviolet detection wavelength.

[0035] Specifically, according to the liquid category, the possible impurity type corresponding to the liquid category is obtained from the first database, and the corresponding ultraviolet detection wavelength is obtained from the second database based on the impurity type, and the ultraviolet detection wavelength corresponding to each impurity type is used as an ultraviolet data to obtain at least two sets of ultraviolet data corresponding to the liquid to be detected.

[0036] Step S203: Generate a detection instruction corresponding to each set of ultraviolet data, and send the detection instruction to the light-emitting module.

[0037] The detection instruction includes the light-emitting time and the rotation angle of the light-emitting module.

[0038] Since the light-emitting module is a rotatable module, the preset number of detections and the detection angle corresponding to each detection number can be obtained. Specifically, the light-emitting duration and rotational movement speed corresponding to each detection of the light-emitting module are obtained, and the first angle between the line formed by the two key points of the light-emitting module and the horizontal line and the second angle between the light-emitting module and the vertical line are obtained, and the required rotation angle from the first angle and the second angle to the detection angle is determined as the rotation angle, and the light-emitting moment of the light-emitting module is calculated based on the rotation angle, the light-emitting duration and the rotational movement speed. Among them, the rotational movement speed is the time required for the light-emitting module to move one degree.

[0039] More specifically, the process of determining the rotation angle can be: obtaining the order of detection angles, and according to the order, and based on the angle of the first detection angle in the horizontal direction and the angle of the vertical direction, determining the first rotation angle required to move the first angle to the angle of the first detection angle in the horizontal direction, and determining the second rotation angle required to move the second angle to the angle of the first detection angle in the vertical direction, the sum of the first rotation angle and the second rotation angle is the angle required for the light-emitting module to rotate from the current position to the first detection angle; and determining the angle required to rotate from the first detection angle to the second detection angle, and so on, to obtain the angle required to rotate from the first angle and the second angle to the last detection angle as the rotation angle.

[0040] The process of calculating the light-emitting time of the light-emitting module can be: based on the angle of rotation required to move from the current position to the first detection angle and the rotation speed, the first light-emitting time corresponding to the first detection angle is obtained, and based on the light-emitting duration of the light-emitting module and the angle of rotation required to move from the first detection angle to the second detection angle and the rotation speed, the second light-emitting time corresponding to the second detection angle is obtained, and so on, to obtain the light-emitting time corresponding to each detection angle.

[0041] Furthermore, a detection instruction including the light-emitting time and the rotation angle is generated, and the detection instruction is sent to the light-emitting module to control the rotation and light-emitting operation of the light-emitting module. The detection instruction may also include an ultraviolet detection wavelength to control the light-emitting module to emit light according to the ultraviolet detection wavelength.

[0042] Step S204: receiving the test results corresponding to each group of test instructions, and determining whether the test results meet the result requirements based on the test results.

[0043] The light-emitting module performs light-emitting and rotation operations according to the detection instructions. The detection module (such as a photoelectric sensor, a spectrometer, etc.) receives and records the fluorescence signal generated by the liquid under ultraviolet light excitation, and sends the fluorescence signal to the electronic device. The electronic device converts the received fluorescence signal into digital data and compares it with a preset threshold or standard data to determine whether there are impurities and their content.

[0044] Step S205: If the detection result meets the result requirement, the detection result is used as the impurity detection result of the liquid to be detected.

[0045] Analyze whether all test results meet the preset result requirements (such as impurity content is lower than a certain value, specific impurities are not detected, etc.). If all test results meet the requirements, the final test result is output as the impurity test result of the liquid to be tested. If it does not meet the requirements, an impurity alarm message is generated.

[0046] The embodiment of the present application provides an impurity monitoring method based on ultraviolet fluorescence, which has a unique effect.

[0047] In a possible implementation of the embodiment of the present application, in the above step S202, when the ultraviolet data includes the wavelength of ultraviolet light, determining at least two sets of ultraviolet data corresponding to the liquid to be detected based on the liquid category corresponding to the liquid to be detected may specifically include: Obtain each impurity type corresponding to the liquid type, and determine the absorbable wavelength range corresponding to each impurity type; Based on the absorbable wavelength range, at least two ultraviolet wavelengths corresponding to the liquid to be detected are determined to obtain at least two sets of ultraviolet data corresponding to the liquid to be detected.

[0048] The second database includes the absorbable wavelength range corresponding to each miscellaneous type.

[0049] Specifically, according to the liquid category, the possible impurity type corresponding to the liquid category is obtained from the first database, and based on the impurity type, the corresponding absorbable wavelength range is obtained from the second database.

[0050] Further, based on the absorbable wavelength range of each impurity type, at least two ultraviolet wavelengths that can cover these ranges or target specific key impurities are selected. These wavelengths should be able to excite the impurity molecules and produce detectable fluorescence signals. The selected ultraviolet wavelengths are combined with corresponding detection parameters (such as detection time, luminescence intensity, etc.) into at least two sets of ultraviolet data to guide the subsequent operation of the light-emitting module and the detection process.

[0051] A possible implementation of the embodiment of the present application, in the above embodiment, generating a detection instruction corresponding to each set of ultraviolet data may specifically include: Obtaining the circumference of the container corresponding to the liquid to be detected and the rotation speed of the light-emitting module; Determine the number of inspections and the inspection angle based on the container length and container width; Determine the rotation angle corresponding to each detection angle; Determining a light-emitting time of the light-emitting module based on a rotation speed and a rotation angle of the light-emitting module; Based on the light-emitting time and rotation angle of the light-emitting module, a detection instruction corresponding to each set of ultraviolet data is generated.

[0052] The rotation speed is the time required for the light emitting module to move one degree. The container perimeter is the perimeter of the container cross section, that is, the perimeter of the cross section horizontal to the liquid surface.

[0053] Specifically, the container model of the liquid container to be detected entered by the staff is received, and the basic data of the container corresponding to the container model is searched to calculate the container perimeter based on the basic data of the container. The basic data of the container includes the cross-sectional shape of the container and the length data corresponding to the cross-sectional shape. The length data corresponding to the cross-sectional shape can be the diameter corresponding to the circle or the length and width corresponding to the rectangle. More specifically, based on the container perimeter of the liquid container to be detected, the perimeter range to which the container perimeter belongs is determined, and the number of detections corresponding to the perimeter range to which it belongs is obtained as the number of detections corresponding to the liquid to be detected, and the detection angle corresponding to the perimeter range to which it belongs is obtained to obtain the number of detections and the detection angle corresponding to the liquid to be detected. One perimeter range corresponds to one detection number and one detection angle. For example, if the perimeter range is (10cm, 15cm], and the number of detections corresponding to the perimeter range is 3, then the perimeter range corresponds to 3 detections.

[0054] Further, after obtaining the number of detections and the detection angle corresponding to the liquid to be detected, the first angle between the line formed by the two key points of the light-emitting module and the horizontal line and the second angle between the light-emitting module and the vertical line are obtained, and the angle of rotation required to rotate from the first angle and the second angle to the detection angle is determined as the rotation angle. Specifically, the order of the detection angles can be obtained, and according to the order, and based on the angle of the first detection angle in the horizontal direction and the angle of the vertical direction, the first rotation angle required to move the first angle to the angle of the first detection angle in the horizontal direction is determined, and the second rotation angle required to move the second angle to the angle of the first detection angle in the vertical direction is determined, and the sum of the first rotation angle and the second rotation angle is the angle required to rotate the light-emitting module from the current position to the first detection angle; and the angle required to rotate from the first detection angle to the second detection angle is determined, and so on, to determine the angle required to rotate from the first angle and the second angle to the last detection angle as the rotation angle.

[0055] Furthermore, after obtaining the rotation angle corresponding to each detection angle, the corresponding light-emitting duration of the light-emitting module can be obtained, and based on the angle and rotation speed required to rotate from the current position to the first detection angle, the first light-emitting moment corresponding to the first detection angle can be obtained, and based on the light-emitting duration of the light-emitting module and the angle and rotation speed required to rotate from the first detection angle to the second detection angle, the second light-emitting moment corresponding to the second detection angle can be obtained, and so on, to obtain the light-emitting moment corresponding to each detection angle.

[0056] Furthermore, after obtaining the light-emitting time and rotation angle of the light-emitting module, a detection instruction including the light-emitting time and the rotation angle can be generated, and the detection instruction can be sent to the light-emitting module to control the rotation and light-emitting operation of the light-emitting module. At the same time, the detection instruction can also include an ultraviolet detection wavelength to control the light-emitting module to emit light according to the ultraviolet detection wavelength.

[0057] A possible implementation manner of the embodiment of the present application, in the above embodiment, determining the rotation angle corresponding to each detection angle may specifically include: Acquire the current state of the light-emitting module and the relative position of the light-emitting module and the container of the liquid to be detected; A three-dimensional coordinate system is established based on the relative position of the light-emitting module and the container of the liquid to be detected; Based on the current form of the light-emitting module, determine the corresponding three-dimensional coordinates of each vertex of the light-emitting module; Determine the current angle between the light-emitting module and the container of the liquid to be detected; Based on each detected angle and the current angle, a rotation angle corresponding to each detected angle is determined.

[0058] After the light-emitting module completes the detection of a liquid to be detected, it will return to the preset initial position and maintain the preset initial shape. When performing the next detection of the liquid to be detected, the light-emitting module will rotate from the preset initial position to move to the position corresponding to the detection angle. Therefore, the preset initial position and the preset initial shape of the light-emitting module can be obtained, and the position of the container of the liquid to be detected can be obtained. Based on the initial position of the light-emitting module and the position of the container, the relative position of the light-emitting module and the container of the liquid to be detected can be determined.

[0059] Furthermore, based on the relative position of the light-emitting module and the container, a three-dimensional coordinate system is established. Specifically, the center point of the container is used as the origin, the length direction of the container is used as the X-axis of the coordinate system, the width direction of the container is used as the Y-axis of the coordinate system, and the height direction of the container is used as the Z-axis of the coordinate system, and the three-dimensional modeling software is used to establish the three-dimensional coordinate system.

[0060] According to the current shape and size of the light-emitting module and its relative position in the three-dimensional coordinate system, the specific position of each vertex (or key point) of the light-emitting module in the three-dimensional coordinate system is determined. Specifically, the vertex coordinates can be directly calculated according to the shape and size of the light-emitting module. Similarly, the vertex coordinates can be calculated according to the shape and size of the container. Further, the first center coordinates of the center point corresponding to each vertex can be determined, and the second center coordinates of the center point corresponding to each vertex of the container can be determined. The first center coordinates and the second center coordinates are connected to obtain a connecting line, and the angles of the connecting line relative to each coordinate axis are determined to obtain the current angle.

[0061] Furthermore, based on the preset detection angle and the current angle between the light-emitting module and the container, the rotation angle corresponding to each detection angle is calculated. The rotation angle refers to the angle that the light-emitting module needs to rotate from the current position to be able to illuminate the specified detection angle position. Specifically, for each detection angle, the difference between it and the current angle is calculated to obtain the angle that needs to be rotated. If the light-emitting module needs to rotate around multiple axes (such as around the X-axis and the Y-axis at the same time), the rotation angle on each axis needs to be calculated separately and synthesized.

[0062] A possible implementation of the embodiment of the present application, in the above embodiment, determining the light-emitting time of the light-emitting module based on the rotation speed and rotation angle of the light-emitting module may specifically include: Based on the current angle and each detected angle, determine the angle to be rotated from the current angle to each detected angle; Based on the rotation speed and the angle to be rotated, determine the rotation time corresponding to each rotation angle; The arrival time corresponding to each rotation duration is determined as the light-emitting time corresponding to the light-emitting module.

[0063] Specifically, according to the current angle of the light module and each preset detection angle, the required rotation angle from the current angle to each detection angle is calculated. All detection angles are traversed, and for each detection angle, the difference between it and the current angle is calculated (note the positive and negative signs, i.e. clockwise or counterclockwise rotation), and the difference obtained is the rotation angle from the current angle to the detection angle.

[0064] Further, based on the rotation speed of the light emitting module and each angle to be rotated, the rotation duration corresponding to each rotation angle is calculated, and the rotation duration is the time required for the light emitting module to rotate from the current position to the specified detection angle. Specifically, the formula "rotation duration = angle to be rotated / rotation speed" is used to calculate the rotation duration corresponding to each rotation angle.

[0065] Furthermore, according to each rotation duration and the starting rotation time of the light-emitting module (which can be assumed to be time 0 or a known time), the arrival time corresponding to each rotation duration is determined, and the arrival time is the time when the light-emitting module should emit light when it rotates to the specified detection angle. Specifically, for each rotation duration, it is added to the starting rotation time to obtain the corresponding arrival time. If the starting rotation time is not time 0, it is necessary to first determine the exact value of the starting rotation time, and use the obtained arrival time as the light-emitting time of the light-emitting module.

[0066] A possible implementation of the embodiment of the present application, in the above embodiment, when the detection result includes the fluorescence intensity and the characteristic wavelength, receiving the detection result corresponding to each group of detection instructions, and determining whether the detection result meets the result requirement based on the detection result, may specifically include: Obtain the fluorescence intensity range and characteristic wavelength range corresponding to the liquid type; Determining a first confidence level corresponding to the fluorescence intensity range and a second confidence level corresponding to the characteristic wavelength range; Determining a fluorescence intensity requirement based on the first confidence level and the fluorescence intensity range, and determining a characteristic wavelength requirement based on the characteristic wavelength range and the second confidence level; Determine whether the fluorescence intensity meets the fluorescence intensity requirement, and determine whether the characteristic wavelength meets the characteristic wavelength requirement, so as to determine whether the detection result meets the result requirement.

[0067] The second database includes the fluorescence intensity range and characteristic wavelength range corresponding to each impurity type. The fluorescence intensity range is the range of fluorescence intensity of the fluorescence emitted by the impurity when it is in an excited state and returns to the ground state through the radiation transition of the fluorescence.

[0068] Specifically, according to the liquid category, the possible impurity type corresponding to the liquid category is obtained from the first database, and based on the impurity type, the fluorescence intensity range and characteristic wavelength range corresponding to the possible impurity type corresponding to the liquid category of the liquid to be detected are obtained from the second database.

[0069] Furthermore, according to experimental requirements or industry standards, a confidence level is assigned to each range (fluorescence intensity range and characteristic wavelength range), each confidence level reflects the degree of trust in the accuracy of the range, and based on these confidence levels, the fluorescence intensity requirements and characteristic wavelength requirements are adjusted or set. Specifically, a first confidence level and a second confidence level are set for the fluorescence intensity range and the characteristic wavelength range, respectively. According to the confidence level and the actual range, the fluorescence intensity requirements and characteristic wavelength requirements are flexibly adjusted. For example, if the confidence level is high, the range can be used directly as the requirement; if the confidence level is low, the required range can be appropriately relaxed or tightened. Among them, the confidence level can be a percentage, a level, or other quantitative indicators.

[0070] Furthermore, the fluorescence intensity and characteristic wavelength actually detected are compared with the fluorescence intensity requirements and characteristic wavelength requirements set previously to determine whether the test result meets the requirements. The detected fluorescence intensity is compared with the fluorescence intensity requirements to check whether it is within the required range. At the same time, the detected characteristic wavelength is compared with the characteristic wavelength requirements to check whether it is also within the required range. If both the fluorescence intensity and the characteristic wavelength meet their respective requirements, the test result is determined to meet the result requirements; otherwise, it is determined not to meet the requirements.

[0071] According to the comparison result, the information of whether the test result meets the requirements is output. If the test result meets the requirements, "the test result meets the standard" or similar information is output; if it does not meet the requirements, an impurity alarm information is generated.

[0072] A possible implementation of the embodiment of the present application, when the detection result does not meet the result requirement, may also include: Determine infrared data corresponding to the liquid to be detected, the infrared data including infrared light wavelength; Controlling the light emitting module to emit infrared light of infrared wavelength; Receive infrared detection results corresponding to infrared light; Based on the infrared detection result and the detection result corresponding to each group of detection instructions, the impurity detection result of the liquid to be detected is determined.

[0073] The second database includes the infrared light wavelength range corresponding to each miscellaneous type.

[0074] When the fluorescence detection result does not meet the requirements, it indicates that there may be impurities or other factors that affect the fluorescence characteristics. At this time, the infrared data of the liquid to be detected can be further obtained to perform infrared spectrum analysis. Specifically, according to the type of the liquid to be detected and the possible impurity components, the infrared light wavelength range or specific wavelength corresponding to the liquid type corresponding to the liquid to be detected is queried from the second database. And the light-emitting module capable of emitting infrared light is controlled to emit infrared light of the corresponding wavelength according to the determined infrared light wavelength.

[0075] When infrared light is irradiated to the liquid to be tested, it will be absorbed, scattered or transmitted by the molecules in the liquid, forming a specific infrared spectrum. These spectral data are received and recorded by detection equipment such as infrared spectrometers. Therefore, the infrared detection results can be compared and analyzed with the known infrared spectrum characteristics of impurities to determine whether there are specific impurities in the liquid to be tested and the type and content of the impurities. Specifically, Use infrared spectrum analysis software to process the recorded spectral data, including preprocessing steps such as denoising and baseline correction. Compare the processed spectral data with the known impurity infrared spectrum library to find matching characteristic peaks or spectral patterns. According to the matching results, determine whether there are impurities in the liquid to be tested, as well as the type and relative content of the impurities. The impurity detection results obtained by analysis are presented in the form of a data table, including information such as impurity type, content, and detection time.
