Description

Technical Field

[0001] This invention relates to the field of control technology for electrical equipment, and specifically to a fragrance release control method, device, electronic device, and storage medium. Background Technology

[0002] Aroma diffusers are primarily used for fragrance diffusion, relieving anxiety, alleviating nasal congestion and allergies, and humidifying the environment. They are often used indoors and in vehicles, such as offices, homes, and cars.

[0003] In related technologies, aroma diffusers typically release fragrance continuously once turned on. Prolonged, continuous release of fragrance can lead to decreased user sensitivity to scents, reducing the therapeutic effect, and also results in wasted fragrance usage.

[0004] As a result, air fresheners that release fragrance at intervals have emerged. However, the fragrance concentration in an air freshener environment may change randomly depending on the environment. For spaces that are always in a closed environment, such as a closed vehicle, on the one hand, adopting a uniform, equal-interval release strategy, which continuously releases the same amount of fragrance when the fragrance concentration in the vehicle is already high, can sometimes have the opposite effect, potentially affecting the driver's state and causing an accident. On the other hand, equal-interval or equal-amount release strategies make it difficult to meet the user's needs for fragrance concentration in the space.

[0005] Therefore, aromatherapy diffusers in related technologies cannot specifically meet user needs. Summary of the Invention

[0006] The purpose of this application is to provide a fragrance release control method, device, electronic device and storage medium, which can adjust the fragrance concentration of the aromatherapy environment in a targeted manner according to user needs.

[0007] According to a first aspect of the embodiments of this application, a fragrance release control method is provided, comprising:

[0008] The fragrance device acquires information about the current concentration of fragrance in the aromatherapy environment;

[0009] Obtain the target concentration information of the fragrance;

[0010] Based on the current concentration information and the target concentration information, a corresponding target fragrance release strategy is determined;

[0011] Fragrance is released based on the target fragrance release strategy.

[0012] In one embodiment, the fragrance device acquires information about the current concentration of fragrance in the aromatherapy environment, including:

[0013] To obtain the quality of the fragrance in the current aromatherapy environment;

[0014] Determine the volume of the aromatherapy environment;

[0015] The current concentration information is determined based on the quality of the fragrance and the volume of the aromatherapy environment.

[0016] In one implementation, the fragrance concentration is calculated as follows:

[0017] c = n / V

[0018] Where c is the fragrance concentration, n is the mass of the fragrance, and V is the volume of the aromatherapy environment.

[0019] In one embodiment, the fragrance device is a car air freshener; the step of acquiring the quality of the fragrance in the current fragrance environment includes:

[0020] Determine the quality of the released fragrance from the car air freshener;

[0021] Determine the amount of fragrance loss from the car air freshener within a first time period; the first time period is from the start time of fragrance release to the current time.

[0022] The quality of the fragrance is determined based on the released fragrance quality and the amount of fragrance loss.

[0023] The quality of the fragrance in the current aromatherapy environment can be determined by comparing the quality of the released fragrance from the start time of fragrance release with the amount of fragrance loss in the first time interval (i.e., the time interval between the start time of fragrance release). This allows for accurate determination of the fragrance quality in the current aromatherapy environment, and consequently, accurate determination of the current fragrance concentration information in the aromatherapy environment. Ultimately, an accurate fragrance release strategy can be selected to achieve precise control of fragrance release.

[0024] In one embodiment, determining the amount of fragrance loss from the car air freshener in a first time period includes:

[0025] Determine the parameter information of the vehicle to which the car air freshener belongs; the parameter information includes the vehicle model;

[0026] After the start time, it is detected whether the vehicle's windows are open;

[0027] If the car window is found to be closed, the activation duration of the car air freshener is determined based on the start time and the current time, i.e., the first time.

[0028] The parameter information and the first time are input into the first fragrance loss prediction model so that the first fragrance loss prediction model outputs the fragrance loss.

[0029] Considering that even when the car windows are closed, the rate of fragrance loss varies depending on the vehicle model and its airtightness, the fragrance loss prediction model trained with a large amount of data on fragrance loss from different vehicle models and different durations of operation of in-car air fresheners can accurately predict the amount of fragrance loss after the in-car air freshener has been on for a certain period of time. This allows for accurate determination of the current fragrance concentration in the air-diffusing environment, and ultimately, the selection of an accurate fragrance release strategy to achieve precise control of fragrance release.

[0030] In one implementation, if the window is detected to be open, the duration of the window's opening, i.e., the second time, is determined.

[0031] The vehicle's parameter information, the first time, and the second time are input into the second fragrance loss prediction model to obtain the fragrance loss amount.

[0032] In one implementation, if the window is detected to be open, the duration of the window's opening, i.e., the second time, is determined.

[0033] Determine whether the second time is less than the preset duration;

[0034] When the window is open for less than a preset duration, the activation duration of the car air freshener is determined based on the start time and the current time.

[0035] Obtain the vehicle's speed information;

[0036] Meteorological data of the vehicle's location is obtained from the terminal device; wherein, the meteorological data includes temperature, air pressure, wind direction, wind speed, and air humidity;

[0037] The parameter information, the first time the car air freshener is turned on, the second time the car window is opened, the driving speed information, and the meteorological data are input into the second fragrance loss prediction model so that the second fragrance loss prediction model outputs the fragrance loss amount.

[0038] Considering that users still have a need for fragrance even when the car windows are open for a short time, and that vehicle model, the duration of the car diffuser's operation, the duration the windows are open, the vehicle's speed, and the weather conditions all affect the amount of fragrance loss, a second fragrance loss prediction model trained with massive amounts of fragrance loss data from different vehicle models, varying durations of car diffuser operation, varying window opening times, varying vehicle speeds, and varying weather conditions can accurately predict the amount of fragrance loss after the car diffuser has been on for a certain period. This allows for accurate determination of the current fragrance concentration in the fragrance environment, ultimately enabling the selection of an accurate fragrance release strategy and precise control over fragrance release.

[0039] In one embodiment, when the second time exceeds the preset duration, the car air freshener is turned off to stop releasing fragrance.

[0040] Considering that users may need to breathe fresh air when the car window is open for a long time and do not need the fragrance to continue to be released, or that continuing to release the fragrance would be wasteful if the window is open for a long time, the car air freshener is turned off and stops releasing the fragrance when it is detected that the car window has been open for longer than the preset time. This can avoid wasting the fragrance and save users money.

[0041] In one embodiment, the car air freshener is equipped with a microphone;

[0042] The detection of whether the vehicle window is open includes:

[0043] Acquire the audio data collected by the microphone;

[0044] Determine whether the increase in the volume of the background noise is greater than a specified increase based on the audio data;

[0045] If the increase in the volume of the background noise is greater than a specified increase, it is determined that the vehicle window is open; if the increase in the volume of the background noise is less than the specified increase, it is determined that the vehicle window is not open.

[0046] By setting a microphone in the car air freshener, the audio data collected by the microphone is obtained. Based on the audio data, it is determined whether the increase in the volume of the background noise is greater than a specified increase, thereby determining whether the vehicle window is open. The data processing volume is small, the data processing speed is fast, and the microphone size is small, which is conducive to the miniaturization of the device.

[0047] In one embodiment, the car air freshener includes a liquid level sensor for detecting the liquid level information of the fragrance in the car air freshener.

[0048] Determining the quality of the released fragrance from the car air freshener includes:

[0049] Acquire the first liquid level information detected by the liquid level sensor at the start time, and the second liquid level information detected at the current time;

[0050] Obtain the density information of the fragrance;

[0051] The volume of released fragrance is determined based on the first liquid level information and the second liquid level information;

[0052] The mass of the released fragrance is determined based on the volume and density information of the released fragrance.

[0053] By installing a liquid level sensor in the car air freshener and detecting the first liquid level information at the start time and the second liquid level information at the current time, the volume of released fragrance can be determined. Then, based on the volume and density information of the released fragrance, the mass of released fragrance can be determined. In this way, the mass of released fragrance can be accurately determined, and thus, the current concentration information of fragrance in the air freshener environment can be accurately determined. Finally, an accurate fragrance release strategy can be selected to achieve precise control of fragrance release.

[0054] In one embodiment, the fragrance device acquires information about the current concentration of fragrance in the aromatherapy environment, including:

[0055] The fragrance device acquires the current concentration information of the fragrance in the fragrance environment at preset time intervals.

[0056] In one embodiment, determining the corresponding target fragrance release strategy based on the current concentration information and the target concentration information includes:

[0057] Based on the current concentration information and the target concentration information, the relative concentration information between the current concentration and the target concentration is determined;

[0058] Based on the relative concentration information and the correspondence between relative concentration and fragrance release strategy, the corresponding target fragrance release strategy is determined.

[0059] Based on the current concentration information and the target concentration information, the relative concentration information between the current concentration and the target concentration is determined. Based on the relative concentration information and the correspondence between the relative concentration and the fragrance release strategy, the corresponding target fragrance release strategy is determined. In this way, no matter how the target concentration information and the current concentration information change, only one correspondence between the relative concentration and the fragrance release strategy needs to be stored, which can reduce storage space and simplify the control logic.

[0060] In one embodiment, before determining the corresponding target fragrance release strategy based on the current concentration information and the target concentration information, the method further includes:

[0061] Receive target concentration information configured from the terminal device.

[0062] The fragrance device can receive target concentration information configured from the terminal device. This allows users to configure the target concentration information through the terminal device to adjust the fragrance concentration of the aromatherapy environment according to their needs.

[0063] In one implementation, determining the target concentration information of the fragrance includes:

[0064] Obtain user identity information;

[0065] The target concentration information is determined based on user identity information and the correspondence between identity information and target concentration.

[0066] The system obtains user identity information and determines the target concentration information based on the user identity information and the correspondence between the identity information and the target concentration. In this way, the target concentration information can be determined according to the user identity information, so as to adjust the fragrance concentration of the aromatherapy environment in a targeted manner according to the user identity.

[0067] In one implementation, obtaining user identity information includes:

[0068] Obtain the user's biometric information;

[0069] The user identity information is determined based on biometric information and the correspondence between biometrics and user identity.

[0070] By acquiring users' biometric information and determining their identity based on this information and the correspondence between biometrics and user identity, users can be accurately identified.

[0071] According to a second aspect of the embodiments of this application, a fragrance release control device is provided, comprising:

[0072] The first acquisition module is configured to acquire the current concentration information of the fragrance in the aromatherapy environment;

[0073] The second acquisition module is configured to acquire the target concentration information of the fragrance.

[0074] The determination module is configured to determine the corresponding target fragrance release strategy based on the current concentration information and the target concentration information;

[0075] The control module is configured to release fragrance based on the target fragrance release strategy.

[0076] According to a third aspect of the embodiments of this application, an electronic device is provided, including a memory and a processor, wherein the memory is used to store a computer program executable by the processor; and the processor is used to execute the computer program in the memory to implement the method described above.

[0077] According to a fourth aspect of the embodiments of this application, a computer-readable storage medium is provided, on which a computer program is stored, which, when executed by a processor, can implement the above-described method.

[0078] According to a fifth aspect of the embodiments of this application, a computer program product is provided, including a computer program or instructions, which, when executed by a processor, implement the method described in the first aspect.

[0079] Compared with existing technologies, the advantages of this application are as follows: It acquires the current concentration information of the fragrance in the aromatherapy environment and the target concentration information of the fragrance through a fragrance device. Then, based on the current concentration information and the target concentration information, it determines a corresponding target fragrance release strategy and releases the fragrance based on the target fragrance release strategy, so that the fragrance concentration in the aromatherapy environment is close to the target concentration. Since the target fragrance concentration information is determined according to user needs, the technical solution provided by this application can adjust the fragrance concentration of the aromatherapy environment in a targeted manner according to user needs.

[0092] Unless otherwise defined, the technical or scientific terms used in this specification and claims shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. Specific embodiments of the invention will be described below with reference to the accompanying drawings. It should be noted that, in order to provide a concise description, this specification cannot provide a detailed description of all features of the actual embodiments. Without departing from the spirit and scope of the invention, those skilled in the art can make modifications and substitutions to the embodiments of the invention, and the resulting embodiments are also within the protection scope of the invention.

[0093] Figure 1 This is a flowchart illustrating a fragrance release control method according to an exemplary embodiment. This fragrance release control method can be applied to fragrance devices; the following description uses a vehicle environment as an example to illustrate the invention. In this embodiment, the fragrance device is a car air freshener. Please refer to... Figure 1 The fragrance release control method may include the following steps:

[0094] Step 101: The fragrance device acquires the current concentration information of the fragrance in the fragrance environment.

[0095] When a user (car owner, driver, or other passengers) enters the vehicle and needs a fragrant environment for relaxation, relaxation, or deodorization and disinfection, they can turn on the car air freshener to release fragrance. However, even for the same type of fragrance, not all fragrance concentrations in the environment will match the user's preferences. Therefore, the air freshener needs to control the fragrance release based on the user's preferred fragrance concentration. To do this, the air freshener must first obtain information about the current fragrance concentration in the environment.

[0096] In this embodiment, the fragrance device can acquire the current concentration information of the fragrance in the aromatherapy environment at preset time intervals. The preset time interval can be a default value or a value set by the user. The user can configure the preset time interval through a terminal device that communicates with the car aromatherapy diffuser. The preset time interval can be 5 seconds, 10 seconds, 15 seconds, 20 seconds, or 30 seconds, but is not limited to these.

[0097] In this embodiment, as Figure 2 As shown, step 101 may include the following steps:

[0098] Step 201: Obtain the quality of the fragrance in the current aromatherapy environment.

[0099] In this embodiment, considering that factors such as the vehicle's airtightness and whether the windows are open can lead to fragrance loss, in order to accurately obtain the quality of the fragrance in the current aromatherapy environment, such as... Figure 3 As shown, step 201 may include the following steps:

[0100] Step 301: Determine the quality of the released fragrance from the car air freshener.

[0101] In this embodiment, a liquid level sensor is installed on the car air freshener to detect the liquid level of the fragrance in the air freshener. The liquid level difference between two time points is determined, and the volume of released fragrance is determined based on the liquid level difference and the cross-sectional area of ​​the bottle containing the fragrance in the car air freshener. Then, the mass of released fragrance between the two time points can be determined based on the volume of released fragrance and the fragrance density.

[0102] In this embodiment, as Figure 4 As shown, step 301 may include the following steps:

[0103] Step 401: Obtain the first liquid level information detected by the liquid level sensor at the start time, and the second liquid level information detected at the current time.

[0104] Step 402: Obtain the density information of the fragrance.

[0105] Step 403: Determine the volume of released fragrance based on the first liquid level information and the second liquid level information.

[0106] Step 404: Determine the quality of the released fragrance based on the volume and density information of the released fragrance.

[0107] In this embodiment, the car air freshener can record the start time of fragrance release when it is turned on, and acquire first liquid level information detected by a liquid level sensor at the start time of fragrance release, and acquire second liquid level information detected by the liquid level sensor at the current time. Then, based on the first and second liquid level information, the liquid level difference between the start time and the current time can be determined. Based on the liquid level difference and the cross-sectional area of ​​the bottle containing the fragrance in the car air freshener, the volume of released fragrance can be determined. Then, based on the volume of released fragrance and the fragrance density information, the mass of released fragrance between the start time and the current time can be determined.

[0108] In this embodiment, the density information of the fragrance can be pre-stored in the car air freshener. When the fragrance types in the car air freshener are replaceable, the car air freshener can pre-store the density information of multiple fragrances, and select one fragrance density information from the multiple fragrance density information as the currently valid fragrance density information according to the received user instruction.

[0109] It should be noted that the execution order between steps 402 and 403 can be interchanged, and is not limited to the execution order in this embodiment.

[0110] In this embodiment, by setting a liquid level sensor in the car air freshener and detecting the first liquid level information at the start time and the second liquid level information at the current time, the volume of the released fragrance is determined. Then, based on the volume and density information of the released fragrance, the mass of the released fragrance is determined. In this way, the mass of the released fragrance can be accurately determined, and thus, the current concentration information of the fragrance in the air freshener environment can be accurately determined. Finally, an accurate fragrance release strategy can be selected to achieve precise control of fragrance release.

[0111] In some embodiments, the amount released by the car air freshener each time within the first time period can also be directly obtained. For example, if some car air fresheners release 0.1ml each time, and if they release a total of 5 times within the first time period, then the amount released within the first time period is 0.5ml.

[0112] Step 302: Determine the amount of fragrance lost from the car air freshener in the first time period. The first time period is the time from the start time of fragrance release to the current time.

[0113] In this embodiment, as Figure 5 As shown, step 302 may include the following steps:

[0114] Step 501: Determine the parameter information of the vehicle to which the car air freshener belongs. The parameter information includes the vehicle model, and may also include supplementary information, such as vehicle condition information and vehicle age information.

[0115] Considering that different vehicle models have varying airtightness, volume, vehicle condition, and age, all of which affect the rate and amount of fragrance loss, and whether the car windows are open also significantly impacts fragrance loss, the first step in determining the amount of fragrance loss is to ascertain the model of the vehicle to which the car air freshener belongs and whether the vehicle windows are open.

[0116] In an exemplary scenario, such as Figure 6 As shown, the car air freshener 61 is communicatively connected to the terminal device 62. Users can configure parameters such as the vehicle model information of the car air freshener 61 via the terminal device 62. The terminal device 62 can be a smartphone or tablet, but is not limited to these. After receiving the vehicle model configuration command from the terminal device 62, the car air freshener 61 parses the vehicle model information from the command and stores it. The terminal device 62 has a control app for the car air freshener installed, allowing users to configure the vehicle model information of the car air freshener 61 and perform other controls via the app.

[0117] Step 502: After the start time, check if the vehicle windows are open. If the windows are not open, proceed to step 503; if the windows are open, proceed to step 505.

[0118] In this embodiment, the car air freshener is equipped with a microphone, which can determine whether the vehicle windows are open by collecting audio data from the microphone.

[0119] In this embodiment, as Figure 7 As shown, step 502 may include the following steps:

[0120] Step 701: Obtain the audio data collected by the microphone.

[0121] Step 702: Determine whether the increase in the volume of the background noise is greater than the specified increase based on the audio data.

[0122] Step 703: If the increase in the volume of the background noise is greater than the specified increase, then it is determined that the vehicle window is open; if the increase in the volume of the background noise is less than the specified increase, then it is determined that the vehicle window is not open.

[0123] In this embodiment, when the car air freshener detects whether the vehicle windows are open, it can acquire audio data collected by a microphone, extract background noise from the audio data, and then determine whether the increase in the volume of the background noise is greater than a specified increase. If the increase in the volume of the background noise is greater than the specified increase, it is determined that the vehicle windows are open; if the increase in the volume of the background noise is less than the specified increase, it is determined that the vehicle windows are not open.

[0124] In this embodiment, a microphone is installed in the car air freshener to acquire audio data collected by the microphone. Based on the audio data, it is determined whether the increase in the volume of the background noise is greater than a specified increase, thereby determining whether the vehicle window is open. The data processing volume is small, the data processing is fast, and the microphone is small, which is conducive to the miniaturization of the device.

[0125] Step 503: Determine the activation duration information of the car air freshener (first time) based on the start time and the current time.

[0126] In this embodiment, the activation duration of the car air freshener can be determined based on the time length between the start time and the current time, and the activation duration information of the car air freshener can be generated, i.e., the first time can be obtained.

[0127] Step 504: Input the vehicle's parameter information and the first fragrance loss prediction model at the first moment so that the first fragrance loss prediction model outputs the fragrance loss amount.

[0128] In this embodiment, the car air freshener can input the vehicle model information and the air freshener's operating duration information into a trained first fragrance loss prediction model, so that the first fragrance loss prediction model outputs the fragrance loss amount. This first fragrance loss prediction model can be a deep learning model, which can automatically calculate the fragrance loss amount based on vehicle parameters and changes in real time. The first fragrance loss prediction model can be located locally on the car air freshener, in the terminal device, or on a remote server. When the first fragrance loss prediction model is located in the terminal device or the remote server, the car air freshener communicates with the terminal device or the remote server and sends a fragrance loss prediction request to the terminal device or the remote server. This request carries the model information and operating duration information. After the first fragrance loss prediction model outputs the fragrance loss amount, the car air freshener receives the fragrance loss amount fed back from the terminal device or the remote server.

[0129] In this embodiment, considering that even when the vehicle windows are not open, the airtightness varies depending on the vehicle model, resulting in different fragrance loss rates, the first fragrance loss prediction model, trained with a large amount of fragrance loss data from different vehicle models and different opening durations of in-vehicle air fresheners, can accurately predict the amount of fragrance loss after the in-vehicle air freshener has been on for a certain period of time. Consequently, the current concentration of fragrance in the air-diffusing environment can be accurately determined, and finally, an accurate fragrance release strategy can be selected to achieve precise control of fragrance release.

[0130] Step 505: Determine the duration of the car window being open (second time).

[0131] Step 506: Determine whether the second time is less than the preset duration. If the second time is less than the preset duration, proceed to step 507; if the second time is greater than the preset duration, proceed to step 511.

[0132] Step 507: Determine the activation duration information of the car air freshener (first time) based on the start time and the current time.

[0133] Next, input the vehicle's parameter information, the first time, and the second time into the second fragrance loss prediction model to obtain the fragrance loss amount. Alternatively, execute steps 508-510.

[0134] Step 508: Obtain the vehicle's speed information.

[0135] Step 509: Obtain meteorological data of the vehicle's location from the terminal device; the meteorological data includes temperature, air pressure, wind direction, wind speed, and air humidity.

[0136] Step 510: Input the vehicle's parameter information, the on-time information of the in-vehicle air freshener (first time), the on-time information of the car window (second time), the driving speed information, and the meteorological data into the second fragrance loss prediction model so that the second fragrance loss prediction model outputs the fragrance loss amount.

[0137] Step 511: Turn off the car air freshener to stop releasing fragrance.

[0138] In this embodiment, considering that opening vehicle windows significantly impacts fragrance loss, and that users may open windows for two reasons—briefly or for extended periods—the fragrance release may still be necessary when the window is briefly open, while prolonged opening may be for ventilation, and continuing to release fragrance would be wasteful. Based on these considerations, the car air freshener first determines the duration the window is open.

[0139] In this embodiment, the car air freshener can determine the duration of the car window being open based on the audio data collected by the microphone, and generate information on the duration of the car window being open. The audio data carries time information.

[0140] In this embodiment, the car air freshener can determine whether the car window is only briefly opened by checking if the window opening duration is less than a preset duration. When the window opening duration is determined to be less than the preset duration, the fragrance release strategy for brief window opening is executed, i.e., steps 507-510.

[0141] In this embodiment, the car air freshener can determine the operating duration information of the car air freshener based on the start time of fragrance release and the current time.

[0142] In this embodiment, the car air freshener is equipped with a speed sensor. The air freshener can obtain the vehicle's speed information through the speed sensor, or it can obtain the speed information by communicating with the vehicle. The rate at which the fragrance dissipates varies depending on the vehicle's speed and the opening of the car windows.

[0143] In this embodiment, the car air freshener can obtain meteorological data of the vehicle's location from a terminal device; the meteorological data includes temperature, air pressure, wind direction, wind speed, and air humidity. The terminal device has a weather app installed, and the app has its location function enabled to provide meteorological data of its location. The car air freshener can obtain the vehicle's location meteorological data by sending a meteorological data request to the terminal device.

[0144] In this embodiment, when the car windows are open, the rate at which the fragrance dissipates varies depending on the weather conditions at the vehicle's location. For example, the rate of fragrance dissipation differs when the vehicle's speed is in the same direction as the wind and when it is in the opposite direction; the rate of fragrance dissipation also varies depending on the wind speed.

[0145] In this embodiment, after determining the operating duration of the car air freshener, acquiring the vehicle's speed information, and obtaining meteorological data of the vehicle's location, the car air freshener inputs the vehicle's parameter information, the operating duration of the air freshener, the window opening duration, the speed information, and the meteorological data into a trained second fragrance loss prediction model, so that the second fragrance loss prediction model outputs the fragrance loss amount. The second fragrance loss prediction model can be a deep learning model. The second fragrance loss prediction model can be located locally on the car air freshener, in the terminal device, or on a remote server. When the second fragrance loss prediction model is located in the terminal device or remote server, the car air freshener communicates with the terminal device or remote server. The car air freshener sends a fragrance loss prediction request to the terminal device or remote server. This request carries vehicle parameter information, information on the duration of the car air freshener's operation, information on the duration of the car windows being open, driving speed information, and weather data. After the second fragrance loss prediction model outputs the fragrance loss amount, the car air freshener receives the fragrance loss amount fed back by the terminal device or remote server.

[0146] In this embodiment, considering that users still have a need for fragrance even when the vehicle windows are open for a short time, and that the vehicle model, the duration of the car diffuser's operation (first time), the duration of the open windows (second time), the vehicle's speed, and the weather conditions at the vehicle's location all affect the amount of fragrance loss, a second fragrance loss prediction model trained with massive amounts of fragrance loss data from different vehicle models, varying durations of the car diffuser's operation, varying durations of the open windows, varying vehicle speeds, and varying weather conditions can accurately predict the amount of fragrance loss after the car diffuser has been on for a certain period. This allows for accurate determination of the current fragrance concentration in the fragrance environment, and ultimately, the selection of an accurate fragrance release strategy to achieve precise control of fragrance release.

[0147] In the above embodiments, the first fragrance loss prediction model and the second fragrance loss prediction model can be constructed by training with simulated data in advance. That is, the prediction model is constructed by simulating the collection of data under different scenarios, and the model output data is compared with real data (e.g., concentration is measured by infrared absorption method) to continuously optimize and construct a prediction model that is close to the real value.

[0148] In this embodiment, when it is determined that the duration of the car window being open is longer than the preset duration, the fragrance release strategy for the case of the car window being open for a long time is executed, namely step 511, turning off the car air freshener and stopping the release of fragrance.

[0149] In this embodiment, considering that when the user keeps the car window open for a long time, the user may need to breathe fresh air and does not need the fragrance to continue to be released, or that continuing to release the fragrance would waste the fragrance if the window is open for a long time, the car air freshener is turned off and the fragrance is stopped when the window is detected to be open for a longer time than a preset time. This can avoid wasting the fragrance and save the user's costs.

[0150] Step 303: Determine the quality of the fragrance based on the quality of the released fragrance and the amount of fragrance loss.

[0151] In this embodiment, the car air freshener determines the quality of the fragrance, i.e. the quality of the fragrance in the current environment, based on the difference between the quality of the released fragrance and the amount of fragrance lost, and then determines the amount to be released, or directly determines the quality of the fragrance to be released.

[0152] In this embodiment, the quality of the fragrance in the current aromatherapy environment is determined based on the quality of the released fragrance from the car air freshener and the amount of fragrance loss from the start time of fragrance release to the current time. This allows for accurate determination of the fragrance quality in the current aromatherapy environment, and consequently, accurate determination of the current concentration information of the fragrance in the aromatherapy environment. Finally, an accurate fragrance release strategy can be selected to achieve precise control of fragrance release.

[0153] Step 202: Determine the volume of the aromatherapy environment.

[0154] In this embodiment, the car air freshener can pre-store the correspondence between vehicle models and volumes. The car air freshener can obtain the vehicle model information and query the pre-stored correspondence between vehicle models and volumes based on the vehicle model information to obtain the volume of the air freshening environment.

[0155] Step 203: Determine the current concentration information based on the quality of the fragrance and the volume of the aromatherapy environment.

[0156] In one embodiment, the car air freshener can determine the current concentration information based on the quality of the fragrance and the volume of the fragrance environment, wherein the formula for calculating the fragrance concentration is:

[0157] c = n / V

[0158] Where c is the fragrance concentration, n is the fragrance mass, and V is the volume of the aromatherapy environment.

[0159] In another embodiment, the fragrance concentration can also be measured by infrared absorption. Specifically, two infrared sensors are set up: one sensor emits light, and the other detects the amount of light absorbed. Since different gases absorb infrared light of different wavelengths, by detecting the amount of absorbed light, the concentration of different gases and the current concentration can be determined. The system can be trained in advance based on fragrances of different concentrations to obtain the current concentration information.

[0160] Step 102: Obtain the target concentration information of the fragrance.

[0161] In this embodiment, prior to step 102, the user can configure the target concentration information of the fragrance via a terminal device. The car air freshener can receive and store the target concentration information configured from the terminal device. This allows the user to configure the target concentration information via the terminal device to adjust the fragrance concentration of the air freshener environment according to their needs.

[0162] In this embodiment, the car air freshener can determine the target concentration information of the fragrance by reading the stored target concentration information.

[0163] In one embodiment, such as Figure 8 As shown, step 102 may include the following steps:

[0164] Step 801: Obtain user identity information.

[0165] Step 802: Determine the target concentration information based on the user's identity information and the correspondence between the identity information and the target concentration.

[0166] In this embodiment, the car air freshener can pre-store the correspondence between user identity information and target concentration. After receiving the user's identity information, the car air freshener queries the correspondence between the identity information and the target concentration to determine the target concentration. In this way, the fragrance concentration of the air freshener can be adjusted in a targeted manner according to the user's identity, improving the flexibility of fragrance release.

[0167] In one embodiment, the car air freshener can obtain user identity information through a terminal device.

[0168] In one embodiment, such as Figure 9 As shown, step 801 may include the following steps:

[0169] Step 901: Obtain the user's biometric information.

[0170] Step 902: Determine user identity information based on biometric information and the correspondence between biometrics and user identity.

[0171] In this embodiment, the car air freshener can pre-store the correspondence between biometric features and user identities. After obtaining the user's biometric information, the car air freshener queries the correspondence between the biometric features and the user's identity to determine the user's identity information. In this way, the user's identity can be accurately determined.

[0172] In one embodiment, the biometric information is fingerprint information. In this embodiment, the car air freshener is equipped with a fingerprint sensor to collect fingerprint information so that the car air freshener can obtain fingerprint feature information.

[0173] In one embodiment, the biometric information is facial feature information. In this embodiment, the car air freshener is equipped with an image sensor for capturing facial images so that the car air freshener can obtain facial feature information.

[0174] In one embodiment, the biometric information is physiological characteristic information. A physiological electrical sensor is installed on the car air freshener to collect physiological information for the air freshener to acquire physiological characteristic information. The physiological electrical sensor can be a blood pressure sensor, a heart rate sensor, or a blood oxygen sensor.

[0175] Step 103: Determine the corresponding target fragrance release strategy based on the current concentration information and the target concentration information.

[0176] In this embodiment, when the current concentration is less than the target concentration, the car air freshener needs to be controlled to continue releasing fragrance until the target concentration is reached. When the current concentration is greater than the target concentration, the car air freshener needs to be controlled to pause releasing fragrance, or reduce the frequency or amount of fragrance release, until the fragrance is reduced to the target concentration.

[0177] In this embodiment, as Figure 10 As shown, step 103 may include the following steps:

[0178] Step 1001: Based on the current concentration information and the target concentration information, determine the relative concentration information between the current concentration and the target concentration.

[0179] Step 1002: Based on the relative concentration information and the correspondence between relative concentration and fragrance release strategy, determine the corresponding target fragrance release strategy.

[0180] In this embodiment, the car air freshener can determine the relative concentration information between the current concentration and the target concentration based on the current concentration information and the target concentration information. The relative concentration information is the difference between the target concentration and the current concentration. Then, based on the relative concentration information and the correspondence between the relative concentration and the fragrance release strategy, the car air freshener determines the corresponding target fragrance release strategy. When the difference is positive, the car air freshener is controlled to continue releasing fragrance until the target concentration is reached. When the difference is negative, the car air freshener is controlled to pause the release of fragrance, or reduce the frequency or amount of fragrance release until the fragrance is reduced to the target concentration. When the difference is 0, the release of fragrance is paused.

[0181] In this embodiment, based on the current concentration information and the target concentration information, the relative concentration information between the current concentration and the target concentration is determined. Based on the relative concentration information and the correspondence between the relative concentration and the fragrance release strategy, the corresponding target fragrance release strategy is determined. In this way, no matter how the target concentration information and the current concentration information change, only one correspondence between the relative concentration and the fragrance release strategy needs to be stored, which can reduce storage space and simplify the control logic.

[0182] Step 104: Release the fragrance based on the target fragrance release strategy.

[0183] In this embodiment, the car air freshener releases fragrance based on the aforementioned target fragrance release strategy, so that the fragrance concentration in the car is close to the target concentration.

[0184] In this embodiment, the current concentration information of the fragrance in the aromatherapy environment is acquired through a fragrance device, and the target concentration information of the fragrance is determined. Then, based on the current concentration information and the target concentration information, a corresponding target fragrance release strategy is determined, and the fragrance is released based on the target fragrance release strategy to make the fragrance concentration in the aromatherapy environment close to the target concentration. Since the target fragrance concentration information is determined according to user needs, the technical solution provided in this application can adjust the fragrance concentration of the aromatherapy environment in a targeted manner according to user needs.
