Description

Technical Field

[0001] This invention relates to the field of vehicle cleaning technology, and in particular to a method and system for automatically cleaning dust inside a vehicle. Background Technology

[0002] With the increasing popularity of automobiles and the rising requirements for in-vehicle air quality, dust and PM2.5 fine particulate matter pollution inside vehicles have become key issues affecting the health and comfort of drivers and passengers. Current methods of cleaning vehicle interiors mostly rely on regular manual washing, which has drawbacks such as long cleaning gaps, continuous dust accumulation, and the potential for secondary dust and pollution.

[0003] Existing publicly available technologies disclose various in-vehicle air purification and dust detection solutions, primarily triggering purification devices by detecting particulate matter concentration to adsorb or filter suspended particulate matter. However, these existing technologies generally suffer from the following shortcomings:

[0004] 1. It mainly relies on passive and periodic cleaning, which cannot achieve real-time dust detection and immediate cleaning, resulting in obvious downtime.

[0005] 2. Most of them only handle airborne particulate matter, and lack effective automatic cleaning methods for dust accumulation on seats, floors, columns, etc.

[0006] 3. Poor matching between detection accuracy and cleaning intensity can easily lead to incomplete cleaning or wasted energy;

[0007] 4. Insufficient ability to control secondary PM2.5 pollution caused by dust accumulation, making it difficult to maintain a clean environment inside the vehicle.

[0008] Therefore, there is an urgent need for an automatic vehicle dust cleaning method and system that can automatically detect, classify, and precisely clean in different zones, while also handling both suspended and deposited dust and effectively suppressing secondary pollution. Summary of the Invention

[0009] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a method and system for automatic cleaning of dust inside a vehicle.

[0010] In a first aspect, embodiments of the present invention provide a method for automatically cleaning dust inside a vehicle, comprising:

[0011] The dust content inside the vehicle is collected by a dust sensor, and the dust concentration value is calculated.

[0012] The dust concentration value is compared with a preset threshold group to determine the dust cleaning level and cleaning method;

[0013] Based on the dust cleaning level and method, the electrostatic adsorption and mechanical vacuuming combined working mode is activated to clean the dust;

[0014] Real-time monitoring of dust concentration changes, and optimization using a zoned and timed circulating purification method based on these changes.

[0015] Furthermore, the dust sensor includes a laser scattering sensor and a photoelectric sensor, which are respectively arranged in the driver's seat, the passenger seat, the rear seat area, and the roof.

[0016] Furthermore, the laser scattering sensor measures dust concentration by emitting a laser beam to irradiate dust particles in the air and measuring changes in the intensity of the scattered light; the photoelectric sensor uses a combination of an infrared light source and a photosensitive element, which generates a blocking effect when dust particles pass through the optical path, and calculates the number and size distribution of dust particles by measuring changes in light intensity.

[0017] Furthermore, the laser scattering sensor includes a laser emitting device and a laser receiving device. The laser emitting device emits laser light, and the laser receiving device receives the scattered light data generated by the laser light passing through fine dust particles inside the vehicle. The particle content inside the vehicle is determined based on the scattered light data, using the following specific calculation formula:

[0018] M 浓度 =K×( -I) / ×C

[0019] Among them, M 浓度 Where K is the concentration of fine dust particles, and K is the calibration coefficient. I represents the incident laser intensity, I represents the received laser intensity, and C represents the environmental correction factor.

[0020] Furthermore, the preset threshold group includes three threshold levels, namely a first threshold, a second threshold, and a third threshold with progressively increasing values; when the dust particle concentration is below the first threshold, it is in a normal state and no cleaning is required; when the dust particle concentration is above the first threshold but below the second threshold, it is in a lightly polluted state and low-power cleaning needs to be started; when the dust particle concentration is above the second threshold but below the third threshold, it is in a heavily polluted state and a powerful cleaning mode needs to be started.

[0021] Furthermore, the size of the dust particles will be judged. When the diameter of the dust particles is smaller than a first threshold, electrostatic adsorption will be used for treatment. When the diameter of the dust particles is larger than a second threshold, mechanical dust collection will be used for treatment. The first threshold is smaller than the second threshold.

[0022] Furthermore, based on the dust cleaning level and method, a combined electrostatic adsorption and mechanical vacuuming working mode is activated to clean the dust, specifically including:

[0023] When the dust level is lightly polluted, low-power electrostatic adsorption is activated to perform localized purification of the vehicle that is difficult to circulate.

[0024] When the dust level is heavily polluted, a combined working mode of electrostatic dust collection, mechanical dust collection, and negative ion dust collection is used to powerfully purify the vehicle.

[0025] Furthermore, real-time monitoring of dust concentration changes is conducted, and a zoned, time-based cyclical purification method is employed for optimization based on these changes. Specific methods include:

[0026] During the cleaning process, sensors continuously monitor changes in dust content. When the dust concentration in the cleaning area drops to a safe range, the cleaning device in that area automatically stops working. For heavily polluted areas, the system will extend the cleaning time or increase the cleaning intensity. The entire cleaning process adopts a zoned and timed strategy. After the cleaning is completed, the system enters a monitoring mode and checks for environmental changes at preset intervals to ensure that the air quality inside the vehicle continues to meet the standards.

[0027] Furthermore, measures include preventing secondary dust pollution. Specific methods include: coating the dust collection plate of the electrostatic dust collector with a special material to prevent the collected dust from being re-scattered; equipping the mechanical dust collector with a three-stage filtration system, including a pre-filter, an activated carbon filter layer, and a HEPA high-efficiency filter, to achieve multi-stage filtration; using carbon fiber electrode material in the negative ion generator to avoid the generation of harmful byproducts such as ozone; and placing the exhaust vent of the cleaning device outside the vehicle to ensure that the cleaned pollutants are completely discharged outside the vehicle and do not circulate inside the vehicle.

[0028] Secondly, this invention also discloses a system for automatically cleaning dust inside a vehicle, comprising: a dust concentration calculation unit, a cleaning level and cleaning method determination unit, a dust cleaning unit, and a cleaning optimization unit; wherein:

[0029] The dust concentration calculation unit is used to collect the dust content inside the vehicle through a dust sensor and calculate the dust concentration value.

[0030] The cleaning level and cleaning method determination unit is used to compare the dust concentration value with a preset threshold group to determine the dust cleaning level and cleaning method.

[0031] The dust cleaning unit is used to activate a combined electrostatic adsorption and mechanical vacuuming working mode to clean the dust according to the dust cleaning level and cleaning method.

[0032] The cleaning and optimization unit is used to monitor changes in dust concentration in real time and optimize the process using a zoned and timed cyclical purification method based on these changes.

[0033] Secondly, the present invention also discloses an electronic device, comprising:

[0034] One or more processors;

[0035] Memory, used to store one or more programs;

[0036] When the one or more programs are executed by the one or more processors, the one or more processors implement the method.

[0037] This invention provides a method and system for automatic dust cleaning inside vehicles. The method includes: collecting dust content data from the vehicle interior using a dust sensor and calculating the dust concentration value; comparing the dust concentration value with a preset threshold group to determine the dust cleaning level and cleaning method; activating a combined electrostatic adsorption and mechanical vacuuming working mode to clean the dust based on the dust cleaning level and cleaning method; and monitoring dust concentration changes in real time and optimizing the process using a zoned and timed cyclical purification method based on the dust concentration changes. This invention eliminates cleaning gaps, efficiently handles both suspended and deposited dust, has high detection accuracy, good cleaning compatibility, and low energy consumption, and can continuously maintain a clean air environment inside the vehicle. It is suitable for intelligent cleaning of cabins in various passenger vehicles.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. Fully automatic real-time cleaning: This invention eliminates the gaps in manual cleaning, enabling dust to be cleaned as soon as it is generated, significantly improving the continuous cleanliness of the vehicle interior;

[0040] 2. Effectively prevents secondary pollution: This invention adopts a closed-loop circulation, anti-desorption dust collection and multi-stage filtration method to suppress the secondary generation of dust pollution from the source;

[0041] 3. Safe and reliable: It has over-temperature protection, dust full reminder and zone temperature control mechanisms, and can operate stably for a long time and is suitable for the whole vehicle environment. Attached Figure Description

[0045] To enable those skilled in the art to better understand the technical solutions of the present invention, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0046] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0047] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0048] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded. Terms such as “connected” or “linked” are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect.

[0049] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0050] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example: appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely locating a specific individual.

[0051] In related technologies, a method for purifying in-vehicle air is disclosed. This method detects the concentration of fine particulate matter in the vehicle and activates a dual purification device when the concentration exceeds a preset value. The first purification device adsorbs the fine particulate matter into a cavity area, while the second purification device removes the fine particulate matter from the cavity area. Existing technologies also propose a method for cleaning a car cabin, which detects the current dust content in the cabin air and compares it with a preset threshold. Based on the comparison result and the vehicle's usage status, the cleaning mode is controlled to be turned on and off. Existing technologies also propose an intelligent control method for in-vehicle air quality, which collects characteristic parameters of different components of gases in the vehicle through multiple sensors, including temperature, humidity, formaldehyde, dust, and carbon dioxide, and controls the corresponding purification equipment through a central processing unit. Existing technologies also disclose a two-stage progressive control air purification system, which determines the air quality index based on the concentration of pollutants and controls different purification methods according to the degree of exceedance. Existing technologies also propose a method for detecting and purifying PM2.5 in vehicles, which detects the PM2.5 value in the vehicle and compares it with a preset value. When the value exceeds the standard, the purification system is activated to purify the air inside the vehicle.

[0052] However, existing technologies still have the following shortcomings: First, current methods of cleaning in-car dust mainly rely on users regularly washing the car interior. This passive cleaning method results in a long gap between cleaning sessions, during which dust continues to accumulate and cannot be effectively removed in a timely manner. Second, most existing automated cleaning systems only deal with suspended particulate matter in the air, lacking effective automated cleaning methods for dust already deposited on the car's interior surfaces. Third, the matching between dust detection accuracy and cleaning efficiency in existing systems needs improvement, often resulting in sensitive detection but incomplete cleaning, or over-cleaning leading to energy waste. Finally, accumulated dust exacerbates the generation of PM2.5 inside the car, causing secondary air pollution and seriously affecting the user's driving experience and health and safety. Existing technologies have limited ability to prevent and control this secondary pollution.

[0053] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a method and system for automatically cleaning dust inside a vehicle;

[0054] This invention provides a method for automatically cleaning dust inside a vehicle, such as... Figure 1 ,include:

[0055] S100. The dust content inside the vehicle is collected by a dust sensor, and the dust concentration value is calculated. In this embodiment, the dust sensor includes a laser scattering sensor and a photoelectric sensor, and the laser scattering sensor and the photoelectric sensor are respectively arranged in the driver's seat, the passenger seat, the rear seat area and the roof.

[0056] In this embodiment, the laser scattering sensor irradiates dust particles in the air with a laser beam and measures the dust concentration based on changes in the intensity of the scattered light; the photoelectric sensor uses a combination of an infrared light source and a photosensitive element, which generates a blocking effect when dust particles pass through the optical path, and calculates the number and size distribution of dust particles by changing the light intensity.

[0057] The laser scattering sensor includes a laser emitting device and a laser receiving device. The laser emitting device emits laser light, and the laser receiving device receives the scattered light data generated by the laser light passing through fine dust particles inside the vehicle. The particle content inside the vehicle is determined based on the scattered light data, using the following specific calculation formula:

[0058] M 浓度 =K×( -I) / ×C

[0059] Among them, M 浓度 Where K is the concentration of fine dust particles, and K is the calibration coefficient. I represents the incident laser intensity, I represents the received laser intensity, and C represents the environmental correction factor.

[0060] Specifically, multiple dust sensors, including laser scattering sensors and photoelectric sensors, are installed inside the vehicle, positioned in the driver's seat, passenger seat, rear seat area, and roof. The laser scattering sensor emits a laser beam to illuminate airborne particles, measuring dust concentration based on changes in scattered light intensity, with a detection accuracy of 0.1 micrograms per cubic meter. The photoelectric sensor utilizes a combination of an infrared light source and a photosensitive element. When dust particles pass through the light path, they create an obstruction effect, and the sensor calculates the number and size distribution of particles by measuring changes in light intensity. The sensors collect data every 30 seconds and transmit the detection data to the vehicle's control unit in real time.

[0061] S200. Compare the dust concentration value with a preset threshold group to determine the dust cleaning level and cleaning method. In this embodiment, the preset threshold group includes three threshold levels: a first threshold, a second threshold, and a third threshold, with values ​​increasing sequentially. When the dust particle concentration is below the first threshold, it is in a normal state and no cleaning is required. When the dust particle concentration is above the first threshold but below the second threshold, it is in a lightly polluted state and low-power cleaning needs to be initiated. When the dust particle concentration is above the second threshold but below the third threshold, it is in a heavily polluted state and a powerful cleaning mode needs to be initiated. In this embodiment, the size of the dust particles is also judged. When the diameter of the dust particles is smaller than the first threshold, electrostatic adsorption is used for processing. When the diameter of the dust particles is larger than the second threshold, mechanical dust collection is used for processing. The first threshold is smaller than the second threshold.

[0062] Specifically, a three-tiered cleaning threshold is set: a dust concentration below 35 micrograms per cubic meter is considered normal; 35-75 micrograms per cubic meter indicates light pollution requiring low-power cleaning; and above 75 micrograms per cubic meter indicates heavy pollution requiring a powerful cleaning mode. The algorithm also analyzes the size distribution of dust particles: fine particles with a diameter less than 2.5 micrometers are handled using electrostatic adsorption, while coarse particles with a diameter greater than 10 micrometers are handled using mechanical vacuuming.

[0063] S300. Based on the dust cleaning level and method, activate the electrostatic adsorption and mechanical vacuuming combined working mode to clean the dust; in this embodiment, activating the electrostatic adsorption and mechanical vacuuming combined working mode to clean the dust based on the dust cleaning level and method specifically includes:

[0064] When the dust level is lightly polluted, low-power electrostatic adsorption is activated to perform localized purification of the vehicle. When the dust level is heavily polluted, a combined working mode of electrostatic dust collection, mechanical dust collection, and negative ion dust collection is adopted to powerfully purify the vehicle.

[0065] Specifically, the vehicle is equipped with three cleaning systems: the first is an electrostatic dust removal system, including high-voltage electrode plates and dust collection plates, operating at 8000 volts, which can effectively adsorb fine dust particles; the second is a negative ion generator, releasing 8 million negative ions per minute, causing dust particles in the air to become charged and settle; the third is a mechanical vacuuming system, equipped with a small turbine fan and a HEPA filter, with a suction power of up to 2000 Pa. The control unit precisely controls the working power and operating time of each cleaning device according to the degree of pollution in different areas.

[0066] S400 monitors dust concentration changes in real time and optimizes the process using a zoned and timed circulating purification method based on these changes.

[0067] In this embodiment, the dust concentration change value is monitored in real time, and the dust concentration change value is used to optimize the process by adopting a zoned and timed cyclical purification method. The specific method includes:

[0068] During the cleaning process, sensors continuously monitor changes in dust content. When the dust concentration in the cleaning area drops to a safe range, the cleaning device in that area automatically stops working. For heavily polluted areas, the system will extend the cleaning time or increase the cleaning intensity. The entire cleaning process adopts a zoned and timed strategy. After the cleaning is completed, the system enters a monitoring mode and checks for environmental changes at preset intervals to ensure that the air quality inside the vehicle continues to meet the standards.

[0069] Specifically, during the cleaning process, sensors continuously monitor changes in dust concentration. When the dust concentration in a certain area drops to a safe range, the cleaning device in that area automatically stops working. For stubbornly polluted areas, the system will extend the cleaning time or increase the cleaning intensity. The entire cleaning process adopts a zoned and time-based strategy to avoid disrupting airflow inside the vehicle by activating all cleaning devices simultaneously. After cleaning is completed, the system enters monitoring mode, detecting environmental changes every 5 minutes to ensure that the air quality inside the vehicle continues to meet standards.

[0070] In this embodiment, a method for automatically cleaning dust inside a vehicle further includes: S500. Controlling secondary pollution from dust, specifically including: coating the surface of the dust collection plate of the electrostatic dust removal device with a special material to prevent the collected dust from being re-scattered; equipping the mechanical dust collection device with a three-stage filtration device, including a pre-filter, an activated carbon filter layer, and a HEPA high-efficiency filter to achieve multi-stage filtration; using carbon fiber electrode material in the negative ion generator to avoid the generation of harmful byproducts such as ozone; and placing the exhaust vent of the cleaning device outside the vehicle to ensure that the cleaned pollutants are completely discharged outside the vehicle and do not circulate inside the vehicle.

[0071] Specifically, to avoid secondary pollution during the cleaning process, the system employs a closed-loop cleaning method. The dust collection plates of the electrostatic precipitator are coated with a special material to prevent collected dust from being re-dispersed. The mechanical vacuum system is equipped with a three-stage filtration system, including a pre-filter, an activated carbon filter layer, and a HEPA high-efficiency filter, achieving a filtration efficiency of 99.97%. The negative ion generator uses carbon fiber electrode material to avoid generating harmful byproducts such as ozone. The exhaust vent of the cleaning device is located outside the vehicle, ensuring that the cleaned pollutants are completely discharged outside the vehicle and do not circulate inside.

[0072] In some preferred embodiments, the dust sensor in this embodiment can also integrate temperature and humidity detection functions to adjust the cleaning strategy according to the temperature and humidity conditions inside the vehicle, thereby improving the targeting and accuracy of the cleaning effect.

[0073] In some preferred embodiments, this embodiment is also equipped with an ultraviolet sterilization device, which sterilizes and disinfects the air inside the vehicle while cleaning dust, further improving the air quality inside the vehicle.

[0074] This embodiment provides a method and system for automatic dust cleaning inside a vehicle. The method includes: collecting dust content inside the vehicle using a dust sensor and calculating the dust concentration value; comparing the dust concentration value with a preset threshold group to determine the dust cleaning level and cleaning method; activating a combined electrostatic adsorption and mechanical vacuuming working mode to clean the dust according to the dust cleaning level and cleaning method; and monitoring the dust concentration change value in real time and optimizing the process using a zoned and timed cyclical purification method based on the dust concentration change value. This invention can eliminate cleaning gaps, efficiently handle suspended and deposited dust, has high detection accuracy, good cleaning matching, and low energy consumption, and can continuously maintain a clean air environment inside the vehicle. It is suitable for intelligent cleaning of cabins in various passenger vehicles.
