[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings. The specific operating methods in the method embodiments can also be applied to device embodiments or system embodiments. It should be noted that in the description of the present invention, "multiple" is understood as "at least two". "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist, and B exists alone. A is connected to B, which can represent: A is directly connected to B and A is connected to B through C. In addition, in the description of the present invention, words such as "first" and "second" are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0040] In order to facilitate understanding by those skilled in the art, the technical terms involved in the present invention are first explained.

[0041] (1) Adenosine triphosphate (ATP) is the core molecule of energy metabolism in organisms and exists in all living cells (bacteria, fungi, etc.). Its concentration can directly reflect cell activity or microbial activity.

[0042] (2) Unity, a game engine, is a real-time three-dimensional (3D) interactive content creation and operation platform. All creators, including game developers, art, architecture, automotive design, and film and television, use Unity to turn their ideas into reality.

[0043] (3) Entity-Component-System (ECS) architecture is a game development architecture that decomposes game objects into components and systems, improving performance and scalability by separating data and behavior. The core idea of ​​ECS is to decompose entities into multiple components, each of which contains specific data, and the system is responsible for processing the data of these components.

[0044] (4) Noise mapping is an image processing technique that is often used in 3D rendering to simulate natural textures and effects, such as the surface texture of materials such as rock, wood, or concrete. By adjusting the noise parameters, the intensity and distribution of the bump effect in the image can be controlled, creating a more realistic or artistic visual effect.

[0045] In the technical solution of the present invention, the acquisition, transmission, storage, and use of data are in compliance with the requirements of relevant national laws and regulations.

[0046] Before introducing the disinfection and sterilization method provided by the present invention, for ease of understanding, the technical background of the present invention is introduced in detail below.

[0047] Related technologies typically employ regular disinfection (e.g., daily or per shift) or passive disinfection in specific scenarios (e.g., after picking up or dropping off high-risk passengers). This approach lacks a quantitative assessment of the actual level of contamination within the vehicle. This approach can lead to either over-disinfection (increasing costs and time) or under-disinfection (failure to respond promptly to sudden pollution events).

[0048] In view of this, the present invention provides a disinfection and sterilization method, apparatus, computer equipment and storage medium to solve the problem in related technologies that the methods of regular disinfection or passive disinfection in specific scenarios may lead to excessive disinfection or insufficient disinfection.

[0049] The disinfection and sterilization method provided by the present invention can be applied to Figure 1 In the disinfection and sterilization system shown, the system includes a microorganism detection unit 102, an environment perception unit 104, a disinfection execution unit 106, and a visualization interaction unit 108. The microorganism detection unit 102 and the environment perception unit 104 are respectively connected to the disinfection execution unit 106, and the disinfection execution unit 106 is also connected to the visualization interaction unit 108.

[0050] Exemplarily, the microbial detection unit 102 is used to obtain microbial parameters in the vehicle, wherein the microbial parameters include at least microbial activity, which can be represented by ATP concentration. The microbial detection unit 102 includes an ATP bioluminescence sensor and an electrostatic adsorption sampling membrane, wherein:

[0051] The ATP bioluminescence sensor is a sensor that uses bioluminescence reaction to detect ATP concentration. It uses luciferase to react with ATP to generate a fluorescent signal. The signal intensity is proportional to the number of microorganisms, providing a real-time contamination index. It is prohibited to use alcohol to wipe.

[0052] The surface of the electrostatic adsorption sampling membrane is coated with a nano-titanium oxide photocatalyst, which efficiently captures microorganisms (such as viruses and bacteria) in the air through electrostatic action. It can also decompose adsorbed organic matter under light, reducing sampling interference. The membrane can be removed (wearing gloves when removing) and sent to the laboratory for testing, accurately identifying specific pathogens and tracing the pathogens. Among them, the user can also be prompted to "Please replace the electrostatic adsorption sampling membrane" according to a preset period (for example, every 90 days).

[0053] Environmental sensing unit 104 is used to obtain environmental parameters within the vehicle, where these environmental parameters include at least the concentration of fine particulate matter (PM2.5) and volatile organic compounds (VOC). Environmental sensing unit 104 includes a PM2.5 sensor and a VOC sensor. The PM2.5 sensor is used to detect the PM2.5 concentration within the vehicle, and the VOC sensor is used to detect the VOC concentration within the vehicle. Environmental sensing unit 104 also includes an infrared human presence detector to detect the presence of people in the vehicle.

[0054] The disinfection execution unit 106 includes an irradiation disinfection module and an ozone generator, wherein the irradiation disinfection module can be a 360-degree rotating short-wave sterilization ultraviolet light emitting diode (UVCLED) module, which depends on the specific situation and is not limited here.

[0055] The UVC LED module is an integrated light source module composed of multiple UV C-band LEDs. Its core feature is that it uses the principle of semiconductor light emission to generate short-wave ultraviolet radiation, which has a highly effective sterilization effect. Manual activation of the UVC LED is prohibited while driving. In addition, the UVC LED's service life can also be monitored. For example, if the UVC LED's service life is expected to be 5000 hours, if the service life decreases to a preset time (for example, 3500 hours), the user will be notified through the vehicle's central control screen.

[0056] An ozone generator is a device that produces ozone, using the strong oxidizing properties of ozone for sterilization, decolorization, deodorization, and wastewater treatment.

[0057] The visualization interaction unit 108 is used to visualize the disinfection process on the vehicle's central control screen. The visualization interaction unit 108 also includes an interface for generating an electronic certification report after the disinfection is completed, so that external devices can obtain the electronic certification report through this interface.

[0058] In the present invention, the method for activating the above-mentioned disinfection and sterilization system for the first time in a vehicle includes but is not limited to: after the vehicle is started, the disinfection and sterilization system authorization agreement is automatically popped up through the vehicle-mounted central control screen. In response to the user checking the box to agree in the disinfection and sterilization system authorization agreement, the user terminal application binding process is initiated. In response to the completion of the binding of the user terminal application, the user is prompted through the vehicle-mounted central control screen to "press and hold the steering wheel custom key for 3 seconds to trigger the detection." In response to the user operation of pressing and holding the steering wheel custom key for 3 seconds, the sensor calibration is started after waiting for 30 seconds (when the external ambient temperature is lower than the preset temperature in winter, the calibration is automatically performed in a certain period, such as every 30 days), and the calibration progress bar is displayed on the vehicle-mounted central control screen. When the calibration progress bar shows 100%, the disinfection and sterilization system is activated for the first time. Among them, after the user terminal application is bound, the daily sterilization trend chart and the high-risk area heat map (marking the seats and steering wheel contamination points) can be viewed in the health file of the user terminal application.

[0059] In the present invention, after the disinfection and sterilization system is activated, it will monitor abnormal conditions in real time to avoid affecting the disinfection efficiency. For example, if the disinfection and sterilization system detects an "E102" error, it will prompt the user to immediately open the window for ventilation and replace the irradiation disinfection module; if the disinfection and sterilization system detects that the visualization of the disinfection process is stuck, it will prompt the user to restart the car (such as pressing the volume "+" and "-" keys at the same time for 10 seconds); if the disinfection and sterilization system detects that it cannot connect to the user terminal application, it will prompt the user to check the fuse of the vehicle remote controller. The specific abnormality depends on the situation and is not limited here.

[0060] The technical solution provided by the present invention is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] Figure 2 A schematic diagram of a disinfection and sterilization method in one embodiment, wherein the method is applied to Figure 1 Taking the disinfection and sterilization system in the example as an example, the process can be executed by a disinfection and sterilization device, which can be implemented by software, hardware, or a combination of software and hardware. Figure 2 As shown, the process includes the following steps:

[0062] S201, obtaining microbial parameters and environmental parameters in the vehicle, and calculating a biological contamination index in the vehicle based on the microbial parameters and environmental parameters;

[0063] S202: Based on the threshold judgment result of the biological contamination index, a differentiated disinfection strategy is implemented.

[0064] Among them, the microbial parameters include at least microbial activity, which can be represented by ATP concentration; the environmental parameters include at least PM2.5 concentration and VOC concentration.

[0065] In the above disinfection and sterilization method, the microbial parameters and environmental parameters inside the vehicle are obtained, and the biological contamination index inside the vehicle is comprehensively calculated to achieve an accurate quantitative assessment of the sanitary conditions inside the vehicle. Based on the threshold judgment results of the biological contamination index, different pollution levels can be intelligently distinguished and differentiated disinfection strategies can be implemented. This can not only avoid excessive disinfection in low-risk scenarios, but also timely perform disinfection treatment in high-risk scenarios.

[0066] In one embodiment, for example, obtaining microbial parameters and environmental parameters in the vehicle in S201 and calculating the biological contamination index in the vehicle based on the microbial parameters and environmental parameters include but are not limited to:

[0067] Obtaining the microbial activity (ATP concentration), PM2.5 concentration, and VOC concentration in the vehicle. For example, the ATP bioluminescence sensor in the microbial detection unit 102 obtains the ATP concentration (unit: relative light unit, representing the degree of microbial contamination); the PM2.5 sensor in the environmental sensing unit 104 obtains the PM2.5 concentration (unit: micrograms per cubic meter); and the VOC sensor in the environmental sensing unit 104 obtains the VOC concentration (unit: milligrams per cubic meter).

[0068] Since microbial activity, PM2.5 concentration, and VOC concentration have different dimensions, they need to be normalized before weighting and calculating them to eliminate the dimension differences of the original data. The specific normalization method depends on the situation and is not limited here.

[0069] Then, the normalized microbial activity, normalized PM2.5 concentration, and normalized VOC concentration are weighted and calculated to obtain the biological pollution index BI, where BI can be in the range of 0-100, depending on the specific situation and is not limited here.

[0070] For example, according to the degree of impact of microbial activity, PM2.5, and VOC on human health, the weight w1 corresponding to the microbial activity m1, the weight w2 corresponding to the PM2.5 concentration m2, and the weight w3 corresponding to the target VOC concentration m3 are determined (such as w1=0.6, w2=0.3, and w3=0.1, the specific values ​​of w1, w2, and w3 depend on the situation and are not limited here), and the weighted sum of m1, m2, and m3 are calculated according to w1, w2, and w3, respectively, to obtain BI=w1*m1+w2*m2+w3*m3.

[0071] Through the above method, the microbial activity, PM2.5 concentration and VOC concentration in the vehicle are obtained in real time, and they are weighted and calculated to obtain the biological pollution index, thereby realizing the quantitative and unified evaluation of multi-source pollution data, overcoming the limitations of single data, accurately reflecting the biological pollution index in the vehicle, and providing a scientific basis for disinfection.

[0072] In one embodiment, for example, the differentiated disinfecting strategy is executed based on the threshold judgment result of BI in S203, including but not limited to:

[0073] If BI is greater than or equal to the first threshold, disinfection is initiated if no one is detected in the vehicle. The specific value of the first threshold depends on the situation and is not limited here.

[0074] For example, if BI is greater than or equal to the first threshold, under the condition that the infrared human presence detector in the environmental perception unit 104 detects that there is no one in the car, the disinfection execution unit 106 controls the irradiation disinfection module (directional disinfection) and the ozone generator to generate ozone to disinfect the interior of the car, ensuring efficient sterilization.

[0075] If BI is less than the first threshold and greater than or equal to the second threshold, then, provided the vehicle is parked, a disinfection confirmation request is sent to the user. Based on the user's response to the disinfection confirmation request, the system determines whether to initiate disinfection. The first threshold is greater than the second threshold, and the specific value of the second threshold depends on the circumstances and is not specified here.

[0076] For example, if the user's feedback to the disinfection confirmation request is "yes", then under the condition that the infrared human presence detector detects that there is someone in the car, the disinfection execution unit 106 controls the irradiation and disinfection module to carry out targeted disinfection in the car. Under the condition that the infrared human presence detector detects that there is no one in the car, the disinfection execution unit 106 controls the irradiation and disinfection module and the ozone generator to generate ozone to disinfect the car. If the user's feedback to the disinfection confirmation request is "no", disinfection will not be started. The specific feedback method depends on the situation and is not limited here.

[0077] If BI is less than the second threshold, disinfection will not be started, and environmental parameters and microbial parameters will be recorded to avoid excessive disinfection.

[0078] Through the above method, intelligent control of in-vehicle disinfection is achieved based on the hierarchical threshold strategy, which not only ensures the timeliness of disinfection, but also improves the user experience, while avoiding the waste of resources under low pollution conditions, and realizing safe, efficient and humane intelligent disinfection management.

[0079] Optionally, according to different threshold intervals, BI can be divided into high risk (BI is greater than or equal to the first threshold), medium risk (BI is less than the first threshold and greater than or equal to the second threshold) and low risk (BI is less than the second threshold), and they can be displayed in different forms on the vehicle's central control screen.

[0080] For example, a floating window is set up on the vehicle's central control screen, which contains at least a pathogen icon. When the risk is high, the pathogen icon is controlled to flash; when the risk is medium, a disinfection countdown is generated in the floating window to prompt the user to confirm whether to start disinfection (this can be determined based on BI or customized. The specific disinfection countdown depends on the situation and is not limited here); when the risk is low, "Good Air Quality" is displayed in the floating window, thus realizing intelligent monitoring of the risk of the vehicle's in-vehicle environment.

[0081] In addition, users can start collecting microbial parameters on the seat surface by clicking the test tube icon in the floating window. At this time, the vehicle needs to remain stationary for a period of time (such as 30 seconds). If the vehicle is detected to be moving, the sampling will be interrupted and a prompt will be given: "Please keep the vehicle stationary for a while."

[0082] Optionally, different disinfection modes can be set for users to choose from, such as smart mode (automatic judgment by the system; disinfection time is 2-15 minutes), strong mode (by long pressing the purification keyboard on the air-conditioning panel, the long press time can be 3 seconds, depending on the specific situation, not limited here; disinfection time is 30 minutes) and child mode (enabled through the application setting of the user terminal; the ozone generator is disabled during pre-disinfection before getting on the vehicle).

[0083] In one embodiment, illustratively, starting the disinfection includes but is not limited to:

[0084] In response to controlling the irradiation and disinfection module to disinfect the interior of the vehicle, the seat height is obtained through the seat sensor, and the irradiation angle of the irradiation and disinfection module is dynamically adjusted according to the seat height.

[0085] For example, if the seat height is greater than the preset height (the initial height of the seat when the vehicle leaves the factory, the specific height depends on the situation and is not limited here), the pitch angle of the irradiation and disinfection module is reduced to tilt the irradiation beam downward and concentrate on irradiating the lower part of the seat (such as the seat cushion, leg space, etc.) to avoid the dispersion of energy due to the shortened irradiation distance caused by the raised seat, and ensure the disinfection intensity of the close area; if the seat height is less than the preset height, the pitch angle of the irradiation and disinfection module is increased to expand the irradiation beam upward to cover farther or higher areas (such as backrests, headrests, etc.) to compensate for the irradiation blind spots that may be caused by lowering the seat. The specific adjustment method depends on the situation and is not limited here.

[0086] Through the above method, the irradiation angle of the irradiation and disinfection module is adjusted based on the seat height, which can eliminate the irradiation blind spots caused by changes in seat height, avoid energy waste while ensuring the disinfection effect, and significantly improve the accuracy and reliability of in-vehicle disinfection.

[0087] In one embodiment, illustratively, starting the disinfection further includes:

[0088] First, the microbial parameters are converted into virtual particles according to a preset rule by the visualization interaction unit 108. The preset rule represents the correspondence between the microbial parameters and the number of virtual particles (for example, the number of virtual particles corresponding to each unit of colony count).

[0089] Then, a virus model is generated based on the virtual particles and rendered to the vehicle's central control screen. For example, using Unity's ECS architecture to render the virus model includes but is not limited to: creating entities and components. In ECS, virtual particles can be viewed as entities with a Transform component (for position, rotation, and scale) and a ParticleSystem component; creating a system to update virtual particle properties such as position and color; and using shaders to render the virus model.

[0090] In response to rendering the virus model to the vehicle's central control screen, the radiation dose value emitted by the irradiation and disinfection module is collected (unit: millijoules per square centimeter. For example, if the irradiation and disinfection module is a UVC LED module, a UVC band-specific photoelectric sensor can be used to collect the ultraviolet radiation dose value. The specific collection method depends on the situation and is not limited here). The surface morphology of the virus model (such as dissolution effect, etc.) is adjusted based on the radiation dose value to visualize the disinfection process. The adjustment method can be:

[0091] The radiation dose value is bound to the dynamic shader parameter, and the corrosion threshold of the virus model is controlled by the noise map. As the radiation dose value increases, the virus model presents a dynamic effect from surface crack expansion, transparency gradient to internal layer-by-layer dissolution.

[0092] Optionally, when the irradiation and disinfection module is a UVC LED module, the visual effect of UVC LED irradiation is simulated by deploying a UVC light spot shader (cyan-blue gradient light effect) to enhance the visual feedback of the disinfection process, wherein the light spot intensity increases with the increase of the ultraviolet radiation dose value.

[0093] Through the above method, the microbial parameters are converted into virtual particles in real time, and a virus model is generated based on the virtual particles and rendered to the vehicle's central control screen. At the same time, the surface morphology of the virus model is adjusted according to the collected radiation dose value emitted by the irradiation and disinfection module. The disinfection process can be visualized, providing users with a real-time and transparent disinfection process, significantly improving the human-computer interaction experience and the credibility of disinfection.

[0094] In one embodiment, it is exemplified that after the disinfection is started, the following steps are further performed:

[0095] The current microbial activity (ATP concentration), current PM2.5 concentration and current VOC concentration in the vehicle are collected in real time through the microbial detection unit 102 and the environmental perception unit 104. If the current microbial activity is less than the first preset value, the current PM2.5 concentration is less than the second preset value, and the current VOC concentration is less than the third preset value, the disinfection is terminated and the irradiation and disinfection module is restored to its initial position. Among them, the first preset value, the second preset value and the third preset value can be determined according to the health and safety standards, or according to empirical values. The specific values ​​depend on the situation and are not limited here.

[0096] Through the above method, when it is monitored that the current microbial activity is less than the first preset value, the current PM2.5 concentration is less than the second preset value, and the current VOC concentration is less than the third preset value, disinfection is automatically terminated, thereby ensuring that the in-vehicle environment meets the hygiene and safety standards while effectively avoiding energy waste and excessive disinfection.

[0097] In one embodiment, it is exemplified that after the disinfection is terminated, the process further includes:

[0098] Generate blockchain evidence containing pre- and post-disinfection comparison data. For example, a hash algorithm is used to generate hash values ​​for biological and environmental parameters before and after disinfection. Then, through a smart contract, key information such as the hash value and timestamp is written to the blockchain and a transaction hash is generated. The transaction hash is ultimately returned to the vehicle as an unalterable verification credential, ensuring data authenticity and traceability, and enabling verifiability of the disinfection process.

[0099] In one embodiment, for example, sending a disinfection confirmation request to a user includes but is not limited to:

[0100] Generate a voice prompt corresponding to the disinfection confirmation request and play the voice prompt; and / or pop up a window on the vehicle's central control screen, where the window is used to prompt the user whether to start disinfection; and / or send the disinfection confirmation request to the user terminal.

[0101] Through the above method, voice prompts can ensure that information can be received while driving without distraction, pop-up windows can provide an intuitive touch operation interface, and sending the disinfection confirmation request to the user terminal can ensure that the user can respond in time even when leaving the car, realizing flexible and reliable human-computer interaction.

[0102] In one embodiment, when disinfecting the interior of a vehicle, a micro-turbine generator installed in the vehicle's air circulation system (such as air conditioning or a dedicated disinfection air duct) can be used to convert the kinetic energy of the forced airflow during disinfection (such as a UVC LED cooling fan or ozone diffusion airflow, etc.) into electrical energy, thereby realizing energy recycling.

[0103] It should be understood that although Figure 2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 2 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0104] In one embodiment, Figure 3 As shown, a disinfection and sterilization device is provided, including: a calculation module 301 and a disinfection module 302, wherein:

[0105] The calculation module 301 is used to obtain microbial parameters and environmental parameters in the vehicle, and calculate the biological contamination index in the vehicle based on the microbial parameters and environmental parameters;

[0106] The disinfection module 302 is used to execute a differentiated disinfection strategy based on the threshold judgment result of the biological contamination index.

[0107] In one embodiment, the calculation module 301 is configured to:

[0108] Obtain microbial activity, fine particulate matter concentration, and volatile organic compound concentration inside the vehicle;

[0109] The microbial activity, fine particulate matter concentration and volatile organic compound concentration are weighted and calculated to obtain the biological pollution index.

[0110] In one embodiment, the disinfection module 302 is used to:
