Description

Technical Field

[0001] This invention belongs to the field of biomedical virus detection and disinfection technology, and relates to a laser detection-disinfection interconnected unmanned system for targeting spreadable biological viruses. Background Technology

[0002] The novel coronavirus primarily spreads through three routes: respiratory droplet transmission (through coughing, sneezing, and talking), direct contact transmission (direct contact with infected patients), indirect contact transmission (contact with droplets exhaled by patients and deposited on surfaces), and aerosol transmission (in environments with high concentrations of aerosols containing the novel coronavirus). While the first three routes can be significantly reduced by avoiding patients or through physical isolation measures such as wearing masks, gloves, and protective clothing, aerosol transmission is more difficult to prevent, especially in enclosed spaces or public places like subways, high-speed trains, airplanes, and conference halls. Not only the novel coronavirus, but many biological viruses also pose a risk of infecting humans through aerosol transmission. This difficulty in preventing infection through physical isolation has become a challenge in epidemic prevention and control. To better address potential future outbreaks of biological viruses, thorough research into rapid and effective detection methods and rapid and effective disinfection and inhibition technologies for these transmission routes is crucial for minimizing their impact.

[0003] Currently, detection technologies for biological viruses both domestically and internationally mainly fall under the categories of contact sampling detection or contact sensor detection. Typical examples in recent years include biosensor technology, PVR technology, reverse transcription-polymerase chain reaction (RT-PCR) technology, quantitative real-time RT-PCR, reverse transcription-loop-mediated isothermal amplification (RT-LAMP) technology, gene chip technology, enzyme-linked immunosorbent assay (ELISA) technology, and rapid detection technology using fluorescent microsphere detection strips. Disinfection methods for biological viruses both domestically and internationally mainly include physical disinfection using heating, X-rays, and ultraviolet light, and chemical disinfection using oxidants, alcohol, alkaline agents, and acidic agents. The rationale is as follows: most viruses are cold-resistant but not heat-resistant, so heating can be used to inactivate them; most viruses can survive at pH values ​​between 5 and 9, so alkaline or acidic agents can be used to soak toxic items; X-rays and ultraviolet rays can inhibit viral nucleotide synthesis, so these rays can be used for close-range irradiation to inactivate viruses; ethanol, formaldehyde, peracetic acid, chlorine-containing disinfectants, alkaline agents, and acidic agents can destroy the structure of some viruses, so these agents can be used for chemical inactivation. However, these traditional detection and disinfection techniques all require specialized laboratory equipment, materials, and skilled personnel. They involve sampling preparation, equipment or material preparation, are time-consuming, and have cumbersome procedures. Furthermore, they are all contact-based or close-range human-operated operations, posing certain safety risks. For biological viral aerosols, traditional detection methods are difficult to implement for rapid sampling and large-area detection, and traditional disinfection methods are difficult to implement for rapid, comprehensive, and long-distance disinfection of infected areas.

[0004] Currently, reports both domestically and internationally on using lasers for simultaneous detection and decontamination of biological viruses are extremely rare. However, lasers possess numerous advantages, including high monochromaticity, concentrated energy, controllable beam, adjustable parameters, environmental friendliness, and suitability for long-distance operation. Furthermore, laser detection of viruses is already well-developed both domestically and internationally. Even though reports on laser decontamination of biological viruses are scarce, it has proven to be a green and efficient decontamination method. Therefore, an integrated detection-decontamination technology that organically combines laser detection and laser decontamination will become an important and feasible approach.

[0005] In the field of future biomedical virus detection and disinfection technology, intelligent, unmanned, and integrated equipment based on multifunctional integration will be the focus of future epidemic prevention medicine development, and also the trend of epidemic prevention medicine towards a safer, greener, and more efficient development. The proposed laser detection-disinfection interconnected unmanned system for spreading biological viruses will play a positive and important role in improving the comprehensive emergency epidemic prevention capabilities in the future. Summary of the Invention

[0006] (I) Purpose of the Invention

[0007] The purpose of this invention is to address the difficulties in sampling, detecting, and targeted disinfection of diffuse biological viruses or aerosols due to their strong diffusion, instability, and large contamination area, which are caused by traditional techniques. Leveraging the advantages of laser propagation speed, good directionality, controllable energy, adjustable parameters, cleanliness, and safety, and based on the mechanism of ultraviolet laser-induced fluorescence spectroscopy detection of biological virus aerosols and ultraviolet laser inactivation of microorganisms, this invention proposes an integrated unmanned system that combines real-time detection and permeable large-area rapid scanning and disinfection. The system's internal power supply control, communication control, timing control, parameter control, and process control are all implemented using programmed intelligent software. The functional modules have high interconnectivity and strong integration, forming an interconnected, integrated, and collaborative operation mode, characterized by intelligence, efficiency, safety, environmental protection, and strong adaptability.

[0008] (II) Technical Solution

[0009] To address the aforementioned technical problems, this invention provides a laser-based real-time detection-decontamination interconnected unmanned system for dealing with diffuse biological viruses. This system is a high-precision, unmanned, remote-controlled system integrating detection and decontamination functions to tackle the challenges of detecting and eliminating biological virus aerosols. Based on the advantages of laser propagation speed, concentrated energy, strong directionality, and controllable energy, which allow for real-time material detection and decontamination, and utilizing the fluorescence spectroscopy detection of ultraviolet laser-induced biological virus aerosols and the mechanism of ultraviolet laser inactivation of microorganisms, this invention employs intelligent integrated control technology and multi-channel common-source optics to design an integrated laser detection-decontamination unmanned system. This system can perform high-precision, real-time, unmanned, and remote integrated detection-decontamination operations on diffuse biological viruses or biological virus aerosols. It is original, practical, and novel in this field.

[0010] The technical principle and approach of this invention are as follows: This invention is based on the detection of biological virus aerosol fluorescence spectroscopy induced by ultraviolet laser and the mechanism of ultraviolet laser inactivation of microorganisms. Generally, most biological viruses exhibit strong absorption characteristics to ultraviolet lasers. Furthermore, due to the different molecular or functional group compositions of different biological viruses, their characteristic absorption spectra and emitted intrinsic fluorescence spectra also differ. Therefore, based on the absorption of a specific wavelength of incident laser and the emitted fluorescence spectrum, the corresponding virus species can be detected and identified. In this invention, a high-energy ultraviolet laser of a specific wavelength is emitted by a laser and, after beam expansion, is incident on the virus aerosol. If the laser wavelength is the characteristic absorption light of the virus, the virus will absorb the laser in that wavelength band and emit fluorescence of the corresponding wavelength. Simultaneously, the aerosol particles will elastically scatter the laser light. These fluorescence signals and elastic scattering signals together form an echo signal, which is received by the system's receiving antenna and, through beam splitting, enters different detectors. The detectors respond to form electrical signals, which, after data acquisition and information analysis, can pinpoint information such as virus species, virus concentration, and target location, thereby achieving the purpose of virus detection and identification. Furthermore, since many biological viruses exhibit strong absorption characteristics to ultraviolet lasers, on the one hand, ultraviolet lasers can induce the formation of thymine dimers and cross-linking of DNA chains, thereby inhibiting viral nucleotide replication; on the other hand, under continuous irradiation by high-energy ultraviolet lasers, the temperature of viral substances rises, and even photoionization, decomposition, vaporization, and ablation occur, thereby achieving an inactivation effect. In this invention, the high-energy ultraviolet laser emitted by the laser is reasonably expanded and collimated to form a large-beam laser, and after being reflected by a large-area scanning mirror, a large-area scanning beam with high energy density is formed. When the energy density of this beam is high enough, it can perform penetrating scanning of viral aerosols over a certain distance, thereby causing ionization, decomposition, vaporization, ablation, and inactivation of the biological virus.

[0011] This invention relates to a laser detection-decontamination interconnected unmanned system for spreading biological viruses, comprising: an intelligent power supply module, an intelligent central control module, a laser source module, and a laser detection-decontamination integrated module. The intelligent power supply module is connected to the intelligent central control module, the laser source module, and the laser detection-decontamination integrated module via power transmission cables and supplies power to each module. The intelligent central control module is connected to the laser source module and the laser detection-decontamination integrated module via communication transmission cables and implements comprehensive control over the working status of each module. The laser source module and the laser detection-decontamination integrated module perform automated, programmed, and unmanned operations according to the processes, timing, and parameter commands set in the intelligent central control module.

[0012] The intelligent power module includes a battery, a power controller, a power switch, a system power control board, power supply cables, and power communication cables. The intelligent power module completes the system power-on and power-off operations by receiving remote wireless commands.

The wireless signal receiver receives external command signals regarding the power switch being turned on or off, identifies and responds through the switch-on / off response program, and then transmits the response result to the power drive motor through a communication cable. After receiving the response result, the power drive motor drives the telescopic switch-off component to extend to turn on or retract to turn off, thereby achieving automatic power-on and power-off.

[0014] The system power control board includes a main control circuit board and a power supply control program. The power supply control program sets the power supply timing, voltage, current and other power supply parameters for each power-consuming unit, component and element in the intelligent main control module, laser source module and laser detection-decontamination integrated module.

[0015] The intelligent central control module includes a central control communication unit and a detection-decontamination integrated control unit, which are used for communication control, workflow, working sequence, and working parameters control of each unit in the laser source module and the laser detection-decontamination integrated module.

It is used to realize the comprehensive control of the opening, operation, and closing of each component in the laser source module and the laser detection-decontamination integrated module.

[0018] The detection-decontamination integrated control program includes a laser wavelength selection algorithm, and the selectable laser wavelengths in the detection-decontamination integrated control program cover all tunable laser wavelengths.

[0019] The laser source module is an ultraviolet pulsed laser. The laser output wavelength is the characteristic absorption wavelength of the target virus, which is used to provide the emitted laser for laser detection and decontamination.

[0020] The integrated laser detection-decontamination module includes a laser emission-scanning unit, a laser receiving and detection unit, a data acquisition unit, and an information processing unit, which are used to implement integrated laser detection-decontamination operations.

[0021] The laser emission-scanning unit includes a high-energy beam collimator and a large-area scanning galvanometer, which are used to extend and collimate the laser output from the laser before emitting it into the target space and to perform large-area beam scanning.

[0022] The large-area scanning galvanometer includes a scanning drive motor, a multi-axis displacement platform, and a large-area optical scanning mirror, which is used to realize laser emission and high-energy-density, wide-range permeation scanning functions.

[0023] Among them, the scanning drive motor drives the multi-axis displacement platform to move, providing scanning power for the large-area scanning galvanometer.

[0024] Among them, the multi-axis displacement platform is a displacement platform with no less than six axes. It is the loading platform for large-area optical scanning mirrors and can realize complex spatial displacement in all directions. During operation, the parameters of each axis of the displacement platform can be adjusted according to the integrated control program command of detection-decontamination to realize different displacement trajectories of the platform.

[0025] Among them, the large-area optical scanning mirror is a large-area total reflection mirror or prism, whose reflection or transmission band covers the output laser band of the laser. According to the different displacement trajectories and displacement velocities of the multi-axis displacement platform, the large-area optical scanning mirror can realize scanning in different orientations, different areas, different rates, and different modes.

[0026] The laser receiving and detection unit includes a receiving antenna, a transmission optical fiber, a focusing lens, a beam splitter, a filter, a photomultiplier tube, or a spectrometer.

[0027] The receiving antenna can receive the elastic scattering signal light of the emitted laser by aerosols and the induced fluorescence signal light of the emitted laser by the target virus. The receiving antenna is connected to the large-area scanning galvanometer by a fixed bearing to ensure that the receiving optical axis of the receiving antenna is always parallel to the emitting optical axis of the large-area scanning galvanometer.

[0028] Among them, the transmission optical fiber can transmit the elastic scattering band of the emitted laser and the fluorescence band signal light induced by the target virus to the emitted laser.

[0029] The focusing lens has three lenses: the first can transmit the elastic scattering wavelength of the emitted laser and the fluorescence wavelength induced by the target virus on the emitted laser; the second only transmits the elastic scattering wavelength of the emitted laser; and the third only transmits the fluorescence wavelength induced by the target virus on the emitted laser.

[0030] Among them, the beam splitter can reflect / transmit the elastic scattering wavelength of the emitted laser, and transmit / reflect the induced fluorescence wavelength of the emitted laser by the target virus.

[0032] Among them, there are two photomultiplier tubes or spectrometers: one that responds to the elastic scattering wavelength of the emitted laser, and the other that responds to the induced fluorescence wavelength of the emitted laser by the target virus.

[0033] The data acquisition board is controlled by the integrated detection-decontamination control program. When the integrated laser detection-decontamination module enters the working state, the integrated detection-decontamination control program automatically transmits the data acquisition command to the data acquisition module. The data acquisition module automatically starts the data acquisition workflow and completes the automatic data acquisition of laser detection echo information.

It can realize intelligent information processing of laser detection data, comparison of processed information with target biological virus characteristic information, and transmission of matching information to the detection-decontamination integrated control program.

[0035] (III) Beneficial Effects

[0036] The laser-based real-time detection and elimination interconnected unmanned system for targeting spreadable biological viruses provided by the above technical solution has the following advantages:

[0037] (1) The system can effectively solve the current domestic and international challenges of high-precision detection and targeted elimination of diffuse biological viruses or toxic bioaerosols. Diffuse biological viruses or toxic bioaerosols exist in different ways than attached biological viruses. Attached biological viruses exist in relatively fixed areas, are easy to find, detect and identify, and are easy to eliminate once detected. However, diffuse biological viruses or toxic bioaerosols are in real-time motion in the environment, are highly unstable and diffuse, involve a large spatial range, are not easy to find, and even if detected and identified, are difficult to eliminate quickly. Therefore, their hazard is often greater than that of attached biological viruses, requiring effective means for rapid detection and elimination. This invention discloses a laser-based real-time detection-disinfection interconnected unmanned system for targeting diffuse biological viruses. Using lasers as a tool, it leverages the advantages of lasers, such as fast propagation speed, strong penetration, good directionality, and controllable energy. It employs ultraviolet laser-induced fluorescence spectroscopy for real-time detection of diffuse biological viruses and high-energy lasers in the strong absorption spectrum of biological viruses for large-area penetrating scanning and disinfection. Through the integrated design of the system's detection and disinfection structures, it can achieve real-time detection and disinfection functions for diffuse biological viruses.

[0038] (2) The system has strong internal interconnectivity and a high degree of intelligence. All components in the system of this invention are controlled by programmed software in terms of parameters, timing, and process, which ensures the integrated and programmed operation of the power supply, communication, detection, and decontamination modules. The internal modules have strong interconnectivity and a high degree of automation and intelligence.

[0039] (3) The system has a high degree of integration between detection and decontamination functions. The laser decontamination function optical structure (high-energy beam collimator → large-area scanning galvanometer) of this invention is directly used as the laser emission function structure of laser detection. It effectively integrates the laser detection and laser decontamination structures into one. Compared with the laser detection function and the laser decontamination function structure being distributed in different systems or in different functional units of a unified system, it has a strong integration feature. Such a system structure is more compact and the functions are more integrated.

[0040] (4) The system is an unmanned system with high efficiency and high safety. The intelligent power supply and intelligent central control module inside the system can realize automated and intelligent integrated control of the laser detection and laser decontamination function modules. It does not require human operation and control, reduces the probability of misoperation, has good work coordination, high efficiency and high safety.

[0041] (5) The system has strong environmental adaptability. The system of this invention is an unmanned system that can enter toxic, harsh environments and areas difficult for humans to access, thus exhibiting strong adaptability. In addition, this equipment system can be transferred as a payload to various platforms such as ground-based, vehicle-mounted, ship / vehicle-based, and airborne platforms, thereby being applied to various environmental areas for the detection and elimination of biological viruses.

[0042] (6) The system is recyclable and has a long lifespan. The system of this invention is an opto-mechatronic system. The power supply module is a rechargeable battery, and the working medium is a laser. All of these are renewable resources and can be recycled. Moreover, the opto-mechatronic system has high maintainability, can be reused repeatedly, has low cost, and has a long lifespan.

[0043] (7) The system operation process is green and environmentally friendly. The system of this invention consumes electricity and uses laser as the medium, which causes less environmental pollution than traditional chemical reagent detection methods and contact disinfection methods such as incineration, rinsing, and compound washing. It is greener and more environmentally friendly. In addition, for the detection and disinfection of biological viruses, the system can operate independently without human intervention, minimizing harm to the human body and protecting the health of the staff.

[0048] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0049] Reference Figures 1 to 4 As shown, this embodiment of the laser real-time detection-decontamination interconnected unmanned system for spreading biological viruses includes: an intelligent power supply module 1, an intelligent central control module 2, a laser source module 3, a laser detection-decontamination integrated module 4, a power supply cable 5, and a communication cable 6.

The battery 7 is connected to the power controller 8, which receives and identifies external command signals regarding the "on" or "off" state of the power switch 9. The power controller 8 is connected to the power switch 9 via the communication cable 26 and transmits the response signal to the power switch 9. The power switch 9 then responds according to the "on" or "off" state. The response signal drives the telescopic conductor-break component 30 to extend and conduct or retract and disconnect. When the external command is "conduct", the power drive motor 29 of the power switch 9 drives the telescopic conductor-break component 30 to extend and conduct, and powers the system power control board 10 through the power supply cable 25. The system power control board 10 then powers the intelligent control module 2, the laser source module 3, and the laser detection-decontamination integrated module 4 through the power supply cable 5. When the external command is "disconnect", the power drive motor 29 of the power switch 9 drives the telescopic conductor-break component 30 to retract and disconnect, the system power control board 10 is de-energized, and all modules of the system are also de-energized.

[0051] The power controller 8 includes a wireless signal receiver 27 and a switch-off response program 28. External command signals are received by the wireless signal receiver 27 and identified and responded to by the switch-off response program 28, and then transmitted to the power drive motor 29 through the power communication cable 26.

The detection-decontamination integrated control unit 34 includes a detection-decontamination integrated control board 37 and a detection-decontamination integrated control program 38. The intelligent control module 2 is used to control the communication, workflow, working sequence, and working parameters of each unit in the laser source module 3 and the laser detection-decontamination integrated module 4. The overall control communication unit 33 includes a communication control circuit 35 and a communication control program 36. The communication control program 36 sets the communication protocols and communication modes for each unit, component, and element in the laser source module 3 and the laser detection-decontamination integrated module 4. The detection-decontamination integrated control unit 34 includes a detection-decontamination integrated control board 37 and a detection-decontamination integrated control program 38. The detection-decontamination integrated control program 38 sets the control algorithms for the working parameters, working sequence, and working process of each unit, component, and element in the laser source module 3 and the laser detection-decontamination integrated module 4, as well as the suspicious information alarm algorithm. The entire detection-decontamination integrated control unit 34 is used to realize the comprehensive control of the opening, operation, and closing of each component in the laser source module 3 and the laser detection-decontamination integrated module 4.

[0053] Laser source module 3 is an ultraviolet laser.

[0054] The laser detection-decontamination integrated module 4 includes a laser emission-scanning unit, a laser receiving and detection unit, a data acquisition unit, and an information processing unit. This module is used to implement laser detection-decontamination integrated operations.

[0055] The laser emission-scanning unit includes a high-energy beam collimator 11 and a large-area scanning galvanometer 12, which are used to extend and collimate the laser output from the laser source module 3 before emitting it into the target space and to perform large-area beam scanning. The high-energy beam collimator 11 and the large-area scanning galvanometer 12 operate in the laser output laser band. The large-area scanning galvanometer 12 includes a scanning drive motor, a multi-axis displacement platform driven by the scanning drive motor, and a large-area optical scanning mirror mounted on the multi-axis displacement platform, which are used to realize laser emission and high-energy-density, large-area penetration scanning functions.

[0056] The laser receiving and detection unit includes a receiving antenna 13, a transmission optical fiber 14, a focusing lens 15, a beam splitter 16, a filter 17, a filter 28, a focusing lens 29, a focusing lens 30, a photomultiplier tube 11, and a photomultiplier tube 22. The receiving antenna 13 receives the elastic scattering signal light of the emitted laser from aerosols and the induced fluorescence signal light of the emitted laser from the target virus, and detects and responds to the signals. The receiving antenna 13 is connected to the transmission optical fiber 14, which transmits the elastic scattering signal light of the laser to aerosols and the induced fluorescence signal light of the emitted laser from the target virus. Signal light in the scattering band and signal light in the induced fluorescence band are incident on focusing lens 15. A beam splitter 16 is arranged on the light-transmitting side of focusing lens 15. A filter 18 is arranged on the light-transmitting side of beam splitter 16. A filter 17 is arranged on the reflective side of beam splitter 16. A focusing lens 19 is arranged on the light-transmitting side of filter 17. Focusing lens 19 focuses the beam onto photomultiplier tube 21. A focusing lens 20 is arranged on the light-transmitting side of filter 28. Focusing lens 20 focuses the beam onto photomultiplier tube 22.

[0057] The data acquisition unit is used for automatic data acquisition of the received and detected echo information.

[0058] The information processing unit is an information processing board that is loaded with information processing software, a target biological virus characteristic data information database, and suspicious characteristic information comparison software. It can realize intelligent information processing of laser detection data, comparison of processed information with target biological virus characteristic information, and transmission of matching information to the detection-decontamination integrated control program 38.

[0059] After passing through the laser emission-scanning unit, the laser performs a large-area penetrating beam scan and decontamination of the target airspace. The echo signal light is received and detected by the laser receiving and detection unit, and the data information is collected, processed, and inverted by the data acquisition unit and the information processing unit. This process is repeated to achieve integrated laser detection and decontamination.

[0060] During operation, the external controller transmits a power-on wireless communication command to the system within a certain distance range. This command is received by the wireless signal receiver 27 and recognized and responded to by the switch-off response program 28. Then, the response signal is transmitted to the power drive motor 29 through the power communication cable 26. The power drive motor 29 drives the telescopic switch-off component 30 to extend and conduct according to the response signal, thereby realizing remote contactless automatic power-on. After the power is turned on, the power supply cable 5 supplies power to the communication control circuit 35 and the detection-decontamination integrated control board 37 in the intelligent master control module 2, supplies power to the laser in the laser source module 3, and supplies power to the power-consuming components (such as the large-area scanning galvanometer 12, receiving antenna 13, photomultiplier tube 21, photomultiplier tube 22, data acquisition board 23, and information processing board 24) in the laser detection-decontamination integrated module 4. The power supply control program 32 automatically sets and allocates the power supply mode, power supply sequence, voltage, current and other power supply parameters of the above-mentioned power-consuming components.

[0061] After the intelligent control module 2, laser source module 3 and laser detection-decontamination integrated optical module 4 are powered on for a few seconds (2 seconds), the intelligent control module 2 automatically starts the communication control program 36 and the detection-decontamination integrated control program 38, and issues automated detection and decontamination commands.

[0062] The detection-decontamination integrated control program 38 first issues instructions starting from the first set laser wavelength, and sends the laser power, laser modulation mode and other parameter instructions set in the program to the laser source module 3 laser through the communication cable between the intelligent central control module 2 and the laser source module 3. The laser receives the program instructions and starts to run, outputting laser with the corresponding parameters.

[0063] Simultaneously, the detection-decontamination integrated control program 38 sends communication commands to the large-area scanning galvanometer 12, data acquisition board 23, and information processing board 24 according to the initial setting parameters, prompting these components to also start operating. When the laser detection-decontamination integrated module 4 starts running, the system is initially in laser detection mode. At this time, the large-area scanning galvanometer 12 remains stationary. The laser emitted by the laser enters the target atmospheric region after passing through the high-energy beam collimator 11 and the large-area scanning galvanometer 12. When the target biological virus aerosol is present in the region, the virus will be induced by the emitted laser to produce fluorescence of the corresponding wavelength, and at the same time, aerosol backscattered elastic light will be generated. These fluorescence signals and aerosol backscattered elastic signals together form an echo signal, which is received by the system receiving antenna 13, and then split into two paths after passing through the transmission fiber 14, focusing lens 15, and beam splitter 16. One path reflected by the beam splitter 16 is the elastic dispersive signal, and the other path transmitted by the beam splitter 16 is the fluorescence echo signal. Subsequently, the elastic dispersive signal passes through filter 17 and focusing lens 19 and enters photomultiplier tube 21 to be converted into an elastic dispersive electrical signal, while the fluorescence echo signal passes through filter 18 and focusing lens 20 and enters photomultiplier tube 22 to be converted into a fluorescence echo electrical signal. Next, the data acquisition board 23 acquires the fluorescence echo electrical signal and the elastic dispersive electrical signal respectively, and sends the data to the signal processing board 24 for processing via a communication cable. The data is then compared with the fluorescence spectral characteristic data of the target biological virus stored in the signal processing board 24. The spectral matching data information is extracted and fed back to the detection-decontamination integrated control program 38. After receiving the matching information, the suspicious information alarm algorithm of the detection-decontamination integrated control program 38 activates the alarm button on the detection-decontamination integrated control board 37. At the same time, after receiving the matching information, the detection-decontamination integrated control program 38 automatically selects parameters from the parameter library, such as laser power, scanning speed, and scanning trajectory, based on the target distance, virus concentration, and other results obtained from the information processing. These parameters are then fed back to the laser source module 3 laser and the large-area scanning galvanometer 12 via a communication cable, resetting the mode and parameters of the laser and the large-area scanning galvanometer 12, thereby starting the permeation scanning decontamination of the target virus aerosol.

[0064] When there is no target biological virus aerosol in the area, the processed information will not match the fluorescence spectral characteristics of the target biological virus, so there will be no alarm, and a "no target virus" command will be sent to the detection-decontamination integrated control program 38. After receiving the command, the detection-decontamination integrated control program 38 will automatically set the next wavelength and feed back to the laser source module 3 laser to output the next wavelength. The large-area scanning galvanometer 12 in the laser detection-decontamination integrated optical module 4 will remain stationary, and the system will continue to perform laser detection-decontamination integrated optical module 4 detection and identification on the target area.

[0065] It is worth noting that the large-area scanning galvanometer 12 and the receiving antenna 13 are connected by a fixed bearing to ensure that the transmitting optical axis of the large-area scanning galvanometer 12 and the receiving optical axis of the receiving antenna 13 are always parallel. This is beneficial because when the large-area scanning galvanometer 12 is scanning, the reflecting telescope 13 can still receive the echo signal in real time, and the system can detect the virus situation in the target area in real time.

[0066] If, after switching all tunable wavelengths, the laser detection-decontamination integrated module 4 still cannot detect the target virus aerosol, or if the laser detection-decontamination integrated optical module 4 detects the target virus while operating at a certain wavelength, but no longer detects the target virus after scanning and decontamination by the large-area scanning galvanometer 12 for a period of time, then the virus is considered to have been completely decontaminated. In either of these cases, the communication control program 36 of the intelligent master control module 2 automatically initiates a communication shutdown command, and the detection-decontamination integrated control program 38 initiates an operation shutdown command, thereby stopping the intelligent master control module 2, the laser source module 3, and the laser detection-decontamination integrated optical module 4, and placing the system in standby mode.

[0067] At this time, the external controller sends a power-off wireless communication command to the system within a certain distance range. The command is received by the wireless signal receiver 27 and identified and responded to by the switch-off response program 28. The response signal is transmitted to the power drive motor 29 through the power communication cable 26. The power drive motor 29 drives the telescopic switch-off component 30 to retract and block, thereby realizing remote contactless automatic power-off.

[0068] As can be seen from the above technical solution, the present invention has the following significant features:

[0069] (1) Effectively solves the problem of high-precision detection and disinfection of spreadable biological viruses.

[0070] (2) Strong internal interconnectivity and high degree of collaborative integration.

[0071] (3) The functional structure is highly integrated and compact.

[0074] (6) It is highly safe and environmentally friendly.

[0075] (7) It has good flexibility and strong adaptability.

[0076] (8) Long lifespan and low operating and maintenance costs.

[0077] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
