[0022] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0023] like Figure 1 As shown, an embodiment of the present invention provides a gas identification processing method, comprising: Step S100: Obtain the target gas and determine the working mode.

[0024] In this embodiment of the invention, the target gas refers to a gas sample to be analyzed in the vehicle cabin environment, and its source can vary depending on the usage scenario. For example, the target gas can be naturally circulating air in the vehicle cabin, including any odors, pollutants, or volatile chemicals that may be present; the target gas can also be the gas actively exhaled by the user. The gas sample of the target gas is captured by a gas sensor module.

[0025] In one embodiment, the gas sensor includes a metal oxide thin film, which works by reacting with the target gas to change its resistance and generate an electrical response signal, thereby acquiring gas characteristics.

[0026] Optionally, the target gas is acquired by a gas sensor at a preset sampling interval.

[0027] In one embodiment, the preset duration is set to 500ms.

[0028] Optionally, the preset duration can be associated with a mode. For example, when in the first mode, the preset duration is set to 500ms; when in the second mode, the preset duration is set to 300ms.

[0029] The working mode is used to indicate the current functional state of the gas identification device, and is used to perform targeted detection of different types of gases in different modes.

[0030] Step S200: When the working mode is the first mode, the target gas is processed according to the first gas processing model to obtain the first processing result.

[0031] In one embodiment, the first mode can refer to a state of continuous monitoring of the vehicle cabin environment, where the target gas originates from the cabin air and contains potentially present odor molecules, volatile pollutants, or harmful chemical components. The first gas processing model represents an odor analysis model built based on artificial intelligence algorithms, specifically designed to process multi-component gas signals in environmental scenarios. The first processing result represents the structured information output by the first gas processing model after analyzing the target gas, such as gas type and the concentration values ​​of each component.

[0032] In one embodiment, the first gas processing model and the second gas processing model can be constructed using different models depending on the specific scenario. For example, when the sample size is small, they can be constructed based on Support Vector Machines (SVM); when the model's anti-overfitting ability is important, they can be constructed using Random Forest. They can also be constructed based on deep learning models, such as convolutional neural networks, recurrent neural networks, or graph neural networks. The trained first and second gas processing models can process the gas features of the target gas to obtain the first processing result and the second processing result.

[0033] Step S300: When the first processing result indicates an anomaly, the target gas is subjected to closed-loop control.

[0034] The first processing result indicating an anomaly means that after analyzing the ambient gas in the vehicle cabin, the first gas processing model determines that there are excessive odor components, harmful substance concentrations exceeding safety thresholds, or a combination of odor characteristics matching typical pollution events. Closed-loop control means that after an anomaly is determined, a series of coordinated actions of in-vehicle equipment can be triggered, forming a complete control loop from perception and analysis to response.

[0035] For example, the controls include devices that can adjust the air quality inside the car, such as the air conditioning circulation mode, the opening and closing status of the windows, and the fragrance release unit. For instance, when smoke is detected, the system can switch to external air circulation, open the windows slightly, release a fresh fragrance, and announce a warning message; when a high concentration of formaldehyde is detected, the system can activate the internal circulation purification mode and activate the negative ion generator.

[0036] Step S400: When the working mode is the second mode, the target gas is processed according to the second gas processing model to generate a gas concentration assessment result.

[0037] In one embodiment, the second mode can refer to a short-term gas sampling state oriented towards individual users, where the gas concentration assessment result represents the structured information output by the second gas processing model after analyzing the target gas. By reusing the gas identification device, the environmental monitoring tool is extended into an individual sensing terminal.

[0038] Optionally, such as Figure 2 As shown, the gas concentration assessment results are generated through the vehicle information service platform (TSP) and transmitted to the user terminal. For example, the TSP receives gas concentration assessment data processed and sent from the vehicle, generates a report from the gas concentration assessment data, and transmits it to the user's mobile terminal, where the report results are displayed via a mobile app.

[0039] In this embodiment, the target gas is acquired and the current scenario is automatically determined. Based on the scenario, functional states are set, and different usage intentions are responded to through the same platform to better meet user needs. In the first scenario, the target gas is processed by a first gas processing model to identify the odor type and pollutant concentration, and a first processing result is output. Upon identifying an environmental anomaly, the in-vehicle execution unit is automatically activated, forming a closed-loop control from perception to intervention. In the second scenario, a second gas processing model is used to analyze the target gas and generate a gas concentration assessment result based on the analysis results. By reusing the same equipment platform, the working mode can be automatically adapted according to the usage scenario. In the corresponding scenario, the focus can be selectively on gas regulation functions or gas concentration assessment functions, achieving diversified gas identification and assessment, and improving the scenario adaptability of the in-vehicle olfactory device.

[0040] Optionally, acquiring the target gas and determining the operating mode includes: In response to the gas identification device being in a wired connection state, the communication type is determined to be wired, and the working mode is determined to be the first mode; In response to the gas identification device not being in the wired connection state, the communication type is determined to be wireless, and the operating mode is determined to be the second mode.

[0041] The communication type refers to the physical connection method used to transmit data between the gas sensor and the central controller, which is divided into wired and wireless types. For example, wired types include physical electrical connections established via USB-C, Lightning, or dedicated interfaces; wireless types include short-range wireless communication protocols such as Bluetooth, Wi-Fi, and UWB.

[0042] When the communication type is wired, it indicates that the sensor module is fixedly installed on the vehicle mount, in a state of continuous power supply and stable data transmission, suitable for long-term, low-interference gas monitoring of the vehicle cabin environment. In this case, the current operating mode is determined to be the first mode, i.e., the vehicle-mounted fixed monitoring mode.

[0043] When the communication type is wireless, it indicates that the sensor module has detached from the fixed base and is uploading exhalation data via a wireless link. This status corresponds to individualized, short-term gas sampling needs, and the current operating mode is determined to be the second mode, i.e., mobile screening mode.

[0044] The physical properties of the communication interface serve as the objective basis for determining the working mode, eliminating the need for additional mode switching switches or manual user selection. Communication types are associated with usage scenarios: wired connections correspond to fixed deployments, while wireless connections are suitable for portable use.

[0045] By improving the reliability of pattern recognition through communication type, functional mismatch can be avoided due to misoperation or software logic errors. It can also realize the automatic alignment of hardware deployment status and software function, so that the first gas processing model or the second gas processing model called later matches the source characteristics of its input data, thereby improving the rationality of overall recognition and evaluation. Ultimately, it achieves the technical effect of automatically adapting the working mode according to the usage scenario and taking into account the diverse gas recognition and evaluation.

[0046] In traditional vehicle-mounted gas detection solutions, environmental monitoring and individual health screening are considered mutually exclusive tasks: the former requires long-term stability, anti-interference capabilities, and low power consumption; the latter requires instantaneous response, high sensitivity, and resistance to humidity interference. These two tasks conflict in terms of sensor operating parameters, signal preprocessing strategies, and model input dimensions. Using the same data type to process both types of data will lead to an increased false alarm rate in environmental mode or a greater risk of missed detections in portable mode. Therefore, simply switching communication interfaces cannot solve the problem; a solution deeply coupled with the specific scenario must be developed.

[0047] Although there are various communication methods for vehicle-mounted devices, most existing olfactory processing devices are designed for a single function. Even if they have wireless transmission capabilities, they are only used for data uploading and do not change their fixed monitoring nature.

[0048] In one embodiment, the communication connection status of the gas identification device is detected in real time; if it is detected that the gas identification device is currently establishing a valid data connection with the vehicle central controller through a wired communication link (e.g., USB Type-C interface), the current communication type is determined to be wired, and the working mode is set to the first mode (i.e., vehicle fixed mode) for continuously collecting in-vehicle environmental gas data and performing environmental health regulation. If the gas identification device is detected to have not established a wired communication link, but has already paired with the vehicle central controller and established a wireless data channel through Bluetooth protocol (e.g., Bluetooth 5.2) or other wireless communication protocols, then the current communication type is determined to be wireless, and the working mode is switched to the second mode (i.e., mobile screening mode) to collect user exhaled gas samples for metabolic abnormality risk assessment.

[0049] For example, connection status can be detected by monitoring the power supply status or handshake signal of the wired interface, querying the currently active interface type of the communication management module, or automatically identifying the communication channel based on the data frame source identifier. No manual switching by the user is required; the system automatically adapts to the appropriate operating mode depending on whether the gas identification device is installed on the base or detached, achieving seamless switching between in-vehicle environmental monitoring and personal health screening scenarios.

[0050] Wired connections naturally correspond to a physical state where the sensor is fixed to the base, continuously powered, and in a stable environmental environment; wireless connections naturally correspond to an interactive state where the sensor is detached from the base, powered by a battery, and the user actively exhales. Through the strong correlation between physical deployment and user intent, the signal type becomes a reliable basis for determining the operating mode.

[0051] Optionally, processing the target gas according to the first gas processing model to obtain the first processing result includes: The gas signal is processed by the first gas processing model to obtain the gas type and gas concentration; The gas type and gas concentration are compared with a preset gas classification concentration standard; When the gas type and / or the gas concentration does not meet the gas classification concentration standard, the first processing result indicates an anomaly. When the gas type and the gas concentration meet the gas classification concentration standard, the first processing result indicates that it is normal.

[0052] In one embodiment, a gas sensor is used to sense and interact with a target gas, outputting a gas signal related to the gas composition to reflect the gas's state and intensity. The first gas processing model is an odor recognition model optimized for the vehicle cabin environment. After receiving the gas signal from the sensor, it analyzes the specific gas type and corresponding concentration value, realizing the conversion from raw sensor data to semantic information. For example, the gas sensor senses the target gas, generating an electrical response signal. This electrical response signal is used as input to the first gas processing model, which then identifies the gas type and concentration value corresponding to the electrical response signal.

[0053] Gas classification concentration standards are a set of thresholds set according to regulations, specifying the upper limit of safe concentration or normal range for different gas types. These standards are used to assess whether the current air quality meets health and comfort requirements. By comparing the gas types and concentrations output by the first gas processing model with the gas classification concentration standards, it can be determined whether there is a risk in the current environment.

[0054] If the comparison results indicate that the gas type belongs to the harmful or odorous category, or its concentration exceeds the corresponding limit, it is considered non-compliant with the standard, and the first processing result indicates abnormality; if the gas type is a common harmless type and the concentration is within the normal range, the first processing result indicates normality.

[0055] In one embodiment, the first gas processing model can be trained according to specific application scenarios. For example, when the application scenario is monitoring indoor air quality, the identifiable gas types include formaldehyde, toluene, ethylbenzene, TVOC, etc.; when the application scenario is outdoor atmospheric monitoring, the identifiable gas types include TVOC, sulfur dioxide, nitrogen oxides, CO, etc.; when the application scenario is hazardous gas detection, the identifiable gas types include methane, hydrogen, carbon monoxide, ethane, propane, etc.; when the application scenario is odor detection, the identifiable gas types include ammonia, hydrogen sulfide, methanethiol, ethanethiol, trimethylamine, etc.; when the application scenario is food freshness detection, the identifiable gas types include TVOC, sulfides, ammonia, methane, ethylene, acetic acid, ethanol, methanethiol, etc.; and when the application scenario is flower and fruit scent identification, the identifiable gas types include various TVOC gases.

[0056] Optionally, the step of performing closed-loop control on the target gas when the first processing result indicates an anomaly includes: Adjust the air conditioning circulation mode to external circulation mode, control the opening of the car windows, and activate the air purification device at least one of the following:

[0057] In one embodiment, such as Figure 2As shown, different types of closed-loop regulation are applied to different gases, controlling different actuators to achieve targeted intervention. For example, when cigarette smoke is detected inside the vehicle, whose main components are particulate matter and volatile organic compounds, the external air circulation mode is activated simultaneously, the windows are opened, and the negative ion generator is activated to accelerate smoke removal and neutralize residual odors. When formaldehyde concentration exceeds the standard, because formaldehyde is released slowly and easily adsorbed onto interior materials, the internal air circulation mode is activated first, combined with activated carbon and photocatalytic purification devices, to avoid introducing external pollution while enhancing decomposition capabilities. When the odor is determined to be ammonia or hydrogen sulfide from food spoilage, the external air circulation mode is switched on and the windows are opened to quickly replace the air and reduce the residence time of irritating gases. By matching the corresponding regulation strategy according to the identified gas type, environmental intervention measures are adapted to the characteristics of the pollution source, improving purification efficiency and user experience.

[0058] Optionally, when the operating mode is the second mode, processing the target gas according to the second gas processing model to generate a gas concentration assessment result includes: The volatile organic components and their concentrations in the target gas are evaluated based on the second gas processing model, and this is taken as the second processing result. The second processing result is compared with a preset reference range to generate the gas concentration assessment result.

[0059] Optionally, when the operating mode is the first mode, the target gas is indicated as ambient air; when the operating mode is the second mode, the ambient gas is indicated as target exhaled gas.

[0060] In one embodiment, the second mode corresponds to a mode that samples the user's exhaled gas, the target gas including a sample of gas actively exhaled by the user containing volatile organic compounds (VOCs) related to human metabolic activities. The second gas processing model represents an identification model specifically designed to analyze such biogenic gases, capable of extracting features from the electrical response signal output by the sensor and assessing the type and concentration of specific VOCs therein as a second processing result.

[0061] The preset reference range refers to the normal concentration range of each volatile organic compound (VOC) based on statistical analysis of exhaled breath data from healthy individuals. The gas concentration assessment result is a structured output generated after comparison, including the measured concentration of each target component, the reference range, and concentration deviation alerts. Concentration deviation alerts are used to guide users to pay attention to the changing trends of relevant health indicators.

[0062] In the second mode, the second gas processing model evaluates the volatile organic components and their concentrations in the target gas to form a second processing result. The second processing result is then compared with a preset reference range to generate a gas concentration assessment result that includes a concentration deviation warning, providing users with non-invasive and convenient metabolic status reference information.

[0063] For example, in the second mode, identifiable gas types include acetone, isoprene, acetaldehyde, hydrogen sulfide, and nitric oxide.

[0064] Optionally, the step of acquiring the target gas and determining the operating mode further includes: The electrical response signal generated by the sensitive material when exposed to the target gas is detected, and feature data for odor identification is generated based on the electrical response signal. The feature data is used as input data for a first gas treatment model or a second gas treatment model.

[0065] Sensitive material refers to the functional layer set in a gas sensor, typically composed of metal oxide semiconductor materials. When exposed to a target gas, its electrical properties undergo measurable changes due to surface adsorption or redox reactions, manifested as changes in parameters such as resistance, current, or impedance, forming an electrical response signal.

[0066] Electrical response signals reflect the intensity and dynamic process of the interaction between sensitive materials and gases, serving as the primary basis for odor identification. Based on these signals, feature data for odor identification is generated through signal conditioning, normalization, and feature extraction. This feature data is a multi-dimensional numerical vector characterizing the response pattern of the target gas and serves as input to subsequent gas processing models. By transforming the chemical information of gas molecules into computable electrical features, the gas processing models can achieve component identification and concentration estimation based on a data-driven approach. The quality of the feature data directly affects the reliability of the identification results; its construction must balance stability, discriminative power, and anti-interference capabilities.

[0067] Acquiring the target gas and determining the operating mode can also be achieved through various gas sensing principles, each corresponding to different electrical response mechanisms and characteristic data generation methods. When using the electrochemical principle, the sensitive material undergoes a redox reaction under the influence of the target gas, generating a current signal proportional to the gas concentration. This current varies with different gas concentrations, and after acquisition and conversion, characteristic data is formed for subsequent identification.

[0068] When using the principle of infrared absorption, the selective absorption of infrared light of specific wavelengths by different gas components is utilized. By monitoring the attenuation of transmitted light intensity, the absorption rate of each component is obtained, and its concentration is then deduced.

[0069] When using the principle of catalytic combustion, the combustible gas undergoes flameless combustion on the catalyst surface, releasing heat that raises the temperature of the heating wire, causing a change in its resistance. The amount of resistance change is related to the gas concentration, and after measurement, characteristic data is generated for identification.

[0070] When using the photoionization principle, the target gas ionizes under ultraviolet light, producing charged particles that generate a weak current under the influence of an electric field. The magnitude of the current is a function of the gas concentration, and the measured current value is used as characteristic data input into the subsequent model.

[0071] When using the thick-film ceramic semiconductor principle, the sensing material is made by coating a ceramic substrate with a thick-film paste, and its resistance value changes with the concentration of the target gas in the environment. The resistance response signal is processed to form characteristic data.

[0072] When employing MEMS semiconductor principles, the sensitive material is a thin film of metal oxide deposited on a silicon substrate. When exposed to a target gas, an adsorption reaction occurs on the film surface, causing a change in resistance. This results in high sensitivity and rapid response characteristics, which are then extracted to generate feature data for odor identification.
