Description
Technical Field
[0001] The present invention belongs to the technical field of on-line detection of solid-phase substances, and in particular relates to a system device and method for spectral collaborative detection of solid-phase substances. Background Art
[0002] As more and more manufacturing and processing companies utilize technologies such as the Internet of Things, cloud computing, and big data, smart factories have formed a technical framework that includes Internet of Things technology, Internet of Things perception technology, data analysis technology, business application technology, and cloud computing technology, ultimately realizing intelligent production under the requirements of modern society.
[0003] Smart factories mean that there are more network connections between factories and enterprises, and resources and information sharing are realized through the Internet, thereby effectively improving the efficiency of each link of production and manufacturing, and enhancing the overall competitiveness of enterprises. In addition, computing and intelligent technologies will be more and more widely used in various links of the production line, and artificial intelligence will be used to optimize and personalize production and manufacturing. Finally, through the continuous improvement of production technology and production characteristics, consumers will be prompted to change their concepts, increase their desire to buy the company's products, and fundamentally change their consumption behavior, thereby increasing the company's turnover.
[0004] Specifically, ensuring the operational success of a smart factory begins with the production workshop. Production requirements must meet the first phase outlined above, ensuring full product connectivity and information sharing. Secondly, an AI management system should be implemented to comprehensively monitor and improve production, product packaging, and quality inspection. Through rational analysis and reallocation of production flow resources, resources can be maximized. Finally, market big data must be collected, planned, and analyzed to identify product types that best meet market demand and implement incremental and quality improvements.
[0005] Specifically, when it comes to the detection of solid-phase substances (finished products and semi-finished products), it can be further divided into qualitative and quantitative detection of inorganic matter, organic matter (organic compounds), and microbial content, depending on the different components. However, during the research process, the inventors found that most existing detection methods can only detect a specific component. For example, the detection methods for organic matter include gas chromatography, liquid chromatography, gas chromatography-mass spectrometry, infrared method, etc.; while the detection methods for inorganic matter include various chemical methods, atomic absorption method, plasma emission spectrometry, fluorescence spectrometry, hydride generation atomic absorption spectrometry, fluorescence method, catalytic polarography, selective ion electrode, volumetric method, potentiometric method, neutron activation analysis method, etc. In addition, most of the above-mentioned detection methods have defects such as long monitoring cycle, complex pretreatment process, presence of secondary pollutants, and can only be carried out in a laboratory environment, which is not conducive to improving the detection efficiency of solid-phase substances.

[0030] The present invention provides a system device and method for spectral collaborative detection of solid-phase substances. The system device for spectral collaborative detection of solid-phase substances has a simple structure, modularity, and high information integration. It can realize in-situ, rapid, comprehensive, and continuous qualitative and quantitative identification and detection, and can provide basic technical support for big data and artificial intelligence detection.
[0031] Example 1
[0032] The present invention provides a system device for spectral coordinated detection of solid phase substances, such as Figure 1 As shown in the figure, the system equipment for spectral collaborative detection of solid-phase substances includes a transmission structure and a spectral collaborative structure. The transmission structure is provided with a conveyor belt, which is used to place and transport the solid-phase substance to be detected; and the spectral collaborative structure includes a hyperspectral component, a terahertz time-domain spectroscopy component, and a laser-induced breakdown spectroscopy component. It is worth noting that hyperspectroscopy has significant advantages in the identification of substances; terahertz time-domain spectroscopy can mainly complete the detection of organic matter in natural environments, especially in distinguishing macromolecular groups; and laser-induced breakdown spectroscopy (LIBS) has significant advantages in the detection of inorganic substances, especially metallic inorganic substances.
[0033] More specifically, Figure 1-Figure 3As shown, the hyperspectral component, terahertz time-domain spectroscopy component, and laser-induced breakdown spectroscopy component are installed sequentially from the conveyor belt inlet to the conveyor belt outlet. The hyperspectral component includes a hyperspectral imager and a hyperspectral data acquisition and analysis module. The terahertz time-domain spectroscopy component includes a fiber-coupled terahertz transmitter module, a fiber-coupled terahertz receiver module, and a terahertz time-domain spectroscopy data acquisition and analysis module. The laser-induced breakdown spectroscopy component includes a laser-induced breakdown spectroscopy transmitter module, a laser-induced breakdown spectroscopy receiver module, and a laser-induced breakdown spectroscopy data acquisition and analysis module.
[0034] Example 2
[0035] The second embodiment includes the complete content of the first embodiment, which is as follows:
[0036] The present invention provides a system device for spectral coordinated detection of solid phase substances, such as Figure 1 As shown in FIG, the system equipment for spectral collaborative detection of solid-phase materials includes a transmission structure and a spectral collaborative structure. The transmission structure is provided with a conveyor belt, which is used to place and transport the solid-phase material to be detected; and the spectral collaborative structure includes a hyperspectral component, a terahertz time-domain spectroscopy component, and a laser-induced breakdown spectroscopy component. Figure 1-Figure 3 As shown, the hyperspectral component, terahertz time-domain spectroscopy component, and laser-induced breakdown spectroscopy component are installed sequentially from the conveyor belt inlet to the conveyor belt outlet. The hyperspectral component includes a hyperspectral imager and a hyperspectral data acquisition and analysis module. The terahertz time-domain spectroscopy component includes a fiber-coupled terahertz transmitter module, a fiber-coupled terahertz receiver module, and a terahertz time-domain spectroscopy data acquisition and analysis module. The laser-induced breakdown spectroscopy component includes a laser-induced breakdown spectroscopy transmitter module, a laser-induced breakdown spectroscopy receiver module, and a laser-induced breakdown spectroscopy data acquisition and analysis module.
[0037] On the basis of the first embodiment, the second embodiment further describes a data acquisition and analysis control unit included in the system equipment for spectral collaborative detection of solid phase substances. Figure 1 As shown, the data acquisition and analysis master control unit establishes data communication interconnection relationships with the hyperspectral data acquisition and analysis module in the hyperspectral component, the terahertz time-domain spectroscopy data acquisition and analysis module in the terahertz time-domain spectroscopy component, and the laser-induced breakdown spectroscopy data acquisition and analysis module in the laser-induced breakdown spectroscopy component.
[0038] It should be noted that the system for collaborative spectral detection of solid-phase materials operates by sequentially and continuously scanning three components: a hyperspectral component, a terahertz time-domain spectroscopy component, and a laser-induced breakdown spectroscopy component. For example, the front end of the solid-phase material (in the direction of the conveyor belt) first enters the hyperspectral component's detection area. The hyperspectral component begins detection, acquiring a hyperspectral spectrum of the solid-phase material. The hyperspectral data acquisition and analysis module then compares the spectrum with a spectral library to determine the types and contents of organic, inorganic, and microbial substances present in the solid-phase material. At time t+3s (e.g., 3 seconds), this section of solid-phase material leaves the hyperspectral component's detection area. At this point, the hyperspectral data acquisition and analysis module transmits the types and contents of the items to be detected to the data acquisition and analysis control unit. This process repeats for the solid-phase material after time t+3s.
[0039] The front end of the solid material (in the direction of the conveyor belt's forward motion) then enters the truncated cone-shaped detection area of the THz time-domain spectroscopy module. The THz time-domain spectroscopy module scans back and forth, collecting a THz time-domain spectral spectrum of the solid material within three seconds. The THz time-domain spectroscopy data acquisition and analysis module then compares the spectra with the spectral library to determine the types and contents of organic, inorganic, and microbial substances present in the solid material. The THz time-domain spectroscopy data acquisition and analysis module then transmits the types and contents of the items to be tested to the data acquisition and analysis control unit. This process is repeated for the solid material three seconds later.
[0040] Finally, the solid-phase material is tested using a laser-induced breakdown spectroscopy component. This testing process is similar to the aforementioned terahertz time-domain spectroscopy component testing process and will not be described in detail here.

[0045] In addition to Example 2, Example 3 further includes a flattening roller. The flattening roller is disposed within the conveyor structure, above the conveyor belt, and is used to flatten the solid-phase material on the conveyor belt into solid-phase sample strips of uniform height. Preferably, the flattening roller flattens the solid-phase material into a flat solid-phase sample strip with a height of 1 cm, facilitating subsequent testing using hyperspectral, terahertz time-domain, and laser-induced breakdown spectroscopy components.

[0056] Example 6
[0057] The present invention also provides a method for spectral collaborative detection of solid-phase substances, which is based on the aforementioned system equipment for spectral collaborative detection of solid-phase substances. Specifically, the solid-phase substance data obtained by the hyperspectral component analysis are defined as HEn, HYn, and HWn; HEn represents the content of the nth inorganic substance analyzed by the hyperspectral component, HYn represents the content of the nth organic substance analyzed by the hyperspectral component, and HWn represents the content of the nth microorganism analyzed by the hyperspectral component.
[0058] Define the solid-phase substance data obtained by analyzing the terahertz time-domain spectroscopy component as TEn, TYn, and TWn; where TEn represents the content of the nth inorganic substance obtained by analyzing the terahertz time-domain spectroscopy component, TYn represents the content of the nth organic substance obtained by analyzing the terahertz time-domain spectroscopy component, and TWn represents the content of the nth microorganism obtained by analyzing the terahertz time-domain spectroscopy component;

[0060] According to the different characteristics of the three detection methods of hyperspectral, terahertz time-domain spectroscopy, and laser-induced breakdown spectroscopy, when qualitatively identifying solid-phase substances, the types of organic substances and microorganisms are mainly based on the terahertz time-domain spectroscopy data, and the types of organic substances and microorganisms contained in the sample are quickly identified by combining the qualitative identification data of hyperspectral; while the types of inorganic substances are mainly based on the laser-induced breakdown spectroscopy data, and the types of inorganic substances contained in the sample are quickly identified by combining the qualitative identification data of hyperspectral. For the specific quantitative detection process (organic substances, microorganisms, inorganic substances), the output rules of the method for spectroscopically co-detecting solid-phase substances are as follows: during the detection of organic substances and microorganisms, when TEn > HEn, TEn > LEn or TEn > HEn, TEn < LEn or TEn < HEn, TEn > LEn, output TEn; when TEn < HEn, TEn < LEn, output TEn when the relative deviation < 50%, and output (Ten + HEn + LEn) / 3 when the relative deviation > 50%; during the detection of inorganic substances, output LWn.
[0061] It should be added that during the process of counting the three spectroscopic data, different colors are used for distinction. When there are discontinuous data in the laser-induced breakdown spectroscopy, the data of the part of the sample with missing data is replaced by the hyperspectral or terahertz time-domain spectroscopy data, mainly based on the data close to the laser-induced breakdown spectroscopy data, and combined with the output rules of the above data.
