TECHNICAL FIELD

[0002] Biochemical substances and biological pathogens are the two most common substances in human living environment, which have a crucial impact on human life and health. With the continuous progress and development of society and the improvement of living standards, the attention to biochemical substances and biological pathogens is getting higher and higher, so the detection of chemical substances and biological pathogens has gradually been valued. As an important means of biochemical substance and biological pathogen detection, optical fiber biochemical sensor has been widely studied, and its excellent performance such as sensitivity and specificity is expected to become the main way of biochemical sensing in the future. Among the optical fiber biochemical sensors, the optical fiber fluorescence biochemical sensor and the optical fiber interferometer biochemical sensor based on fluorescence and interference principle are the most common. The optical fiber fluorescence biochemical sensor can realize qualitative and quantitative detection of biochemical substances or biological pathogens by detecting fluorescence intensity, fluorescence lifetime and other fluorescence characteristics. The optical fiber interferometer biochemical sensor realizes qualitative and quantitative detection of biochemical substances or biological pathogens by detecting the wavelength change of interference spectrum. The optical fiber biochemical sensor has the advantages of high sensitivity and strong anti-interference, and can also realize real-time monitoring at a long distance, which is suitable for monitoring the ecological environment under harsh conditions.

[0045] In an optional scheme of the embodiment, preferably, the automatic integrated manufacturing equipment for the functionalized multi-channel optical fiber sensor provided by the embodiment further comprises a waste liquid treatment module, and a plurality of packaging shells 29 are arranged on the fixed module 7, each packaging shell 29 is provided as a four-way shell, the packaging shell 29 comprises two opposite packaging ports and two opposite functional interfaces, the packaging shells 29 are connected in series through the functional interfaces, one functional interface of the packaging shell 29 on one side is connected and communicated with the functionalization module, and one functional interface of the packaging shell 29 on the other side is connected and communicated with the waste liquid treatment module; the waste liquid treatment module is in communication connection with the control module 15, and the waste liquid treatment module is used for receiving the treatment liquid in each packaging shell 29.

[0046] The waste liquid treatment module includes a waste liquid storage container 14 and a pumping component such as a peristaltic pump 3. The waste liquid storage container 14 is a corrosion-resistant and chemically stable waste liquid storage tank that can be easily disassembled and cleaned to facilitate the collection and treatment of functionalized waste liquid. The pumping component is controlled by the control module 15 to pump out the waste liquid in each sub-encapsulation shell 29 to empty or clean the encapsulation shell 29. The adjacent encapsulation shells 29 are connected by gas-liquid channels 6 to form multiple multi-channel optical fiber sensing unit 11 arrays, which can simultaneously process the encapsulation and functionalization of multiple channel optical fiber sensing units 11, greatly improving the efficiency of preparation.

[0047] In an optional embodiment of the present embodiment, the optical fiber sensing unit 11 is preferably pre-prepared by misalignment fusion, tapering, fused resonant cavity, etched grating, and etching modification. Subsequently, specific substance or physical quantity specific detection can be achieved through encapsulation and functionalization process. The detection of the position of the optical fiber sensing unit 11 is related to the effectiveness of the subsequent functionalization, and image processing and recognition are crucial. The image captured by the high-resolution camera 23 contains the encapsulation shell 29, the optical fiber sensing unit 11 and the gas-liquid channel 6. The encapsulation shell 29 is made of plastic material with a certain degree of transparency, which can observe the internal optical fiber sensing unit 11. The gas-liquid channel 6 is a medium connecting different encapsulation shells 29. The optical fiber sensing unit 11 has different structures and thus different detection methods. Image recognition mainly uses two parallel recognition methods. One is to recognize the shape of the optical fiber sensing unit 11 structure, such as the misalignment structure of the optical fiber misalignment interference structure 28, the slender structure of the tapered optical fiber structure 30 and the spherical echo wall of the optical fiber echo wall structure 31, which are easy to identify directly by shape, then confirm the position of the encapsulation shell 29 where the optical fiber sensing unit 11 is located and adjust the position by controlling the control motor 4. The second is the light capture method. Some structures such as the optical fiber grating structure 32 cannot directly identify the accurate position of the optical fiber sensing unit 11 from the shape. It can be identified by the principle of inputting incident light 27 into the optical fiber to form scattered light 33 on the surface of the optical fiber sensing unit 11. The incident light 27 uses 520nm green light which is the most sensitive to the camera and human eye. When the incident light 27 passes through the optical fiber misalignment interference structure 28, it will produce obvious scattered light 33 on the side of the misalignment structure. When the incident light 27 passes through the tapered optical fiber structure 30, a small amount of scattered light 33 will be produced at the position of the two sides of the taper. When the incident light 27 passes through the spherical echo wall of the optical fiber echo wall structure 31, a small amount of scattered light 33 will be produced. When the incident light 27 passes through the optical fiber grating structure 32, scattered light 33 will be formed on the surface of the periodic structure. By shooting the scattered light 33 image by the camera and identifying its position, the optical fiber sensing unit 11 can be positioned and calibrated. The combination of the two recognition methods can effectively improve the accuracy of detection, and the method is simple and can be completed on the control module 15 throughout the operation, which reduces the calibration time, labor cost and difficulty and improves the calibration efficiency.

[0048] In an optional solution of the embodiment, preferably, the control module 15 is arranged to be connected to each component through wireless or wired communication, as a terminal device such as a computer; the control module 15 can receive the spectral data transmitted by the integrated module 1, and after processing, the data can be presented to the operator in a visualized manner and the functionalization process can be monitored in real time. In addition, the control module 15 can also receive the digital image of the optical fiber sensing unit 11 collected by the image detection module 13, process and identify the position of the optical fiber sensing unit 11 in the packaging shell 29 through a digital image processing algorithm, and adjust the position of the optical fiber sensing unit 11 to the center position of the adjusting motor 4 for position calibration, and then package the optical fiber sensing unit 11, so as to ensure the feasibility and effectiveness of the subsequent functionalization.
