Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle control, and in particular relates to an automatic smoke exhaust method and system for a vehicle, and a vehicle. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the rapid development of intelligent scenarios of automobile companies, consumers are paying more and more attention to in-car comfort, and the diversity of automobile functions has evolved accordingly. Cars are not only a means of transportation, but also the quality of life that everyone pursues.

[0004] More and more car owners are choosing to use their cars to operate online car-hailing services such as SF Express and Didi Taxi. However, smoking by passengers can cause many serious hazards: the driver may feel uncomfortable due to the smoke, which may distract attention from the road and increase the risk of traffic accidents; the smoke will quickly reduce visibility inside the car and interfere with the driver's observation of road conditions; the smell of cigarettes is very stubborn, and even after the smoking behavior ends, the odor in the smoke will remain in the car's fabrics, seats, air-conditioning systems and other corners for a long time, which will not only affect the subsequent passengers' riding experience, but may also cause the vehicle to depreciate; sticky substances such as tar in the smoke will adhere to the air-conditioning vents, dashboard, seats and other components in the car, making them difficult to clean, which not only affects the appearance, but may also corrode these components and shorten their service life.

[0005] In addition, people who are under great pressure in modern society and who often drive for long periods of time on highways and are easily fatigued often smoke to relieve stress, refresh themselves, and relieve fatigue after parking. At present, the traditional ashtrays made by most car companies in the market can only store ashes and cigarette butts. The harmful gases produced by burning cigarettes will not only affect the environment of the entire vehicle and shorten the service life of the vehicle, but also reduce the carbon dioxide content in the car and cause hypoxia.

[0006] Due to the above reasons, it is often necessary to manually open the sunroof or windows, which will affect the driving of private car owners, and some passengers are afraid of the cold and will object to opening the windows. In addition, in rainy and snowy weather or when air conditioning is turned on in summer and winter, it is not suitable to open the sunroof or windows, and the internal circulation needs to be turned on manually. This method cannot reduce the damage caused by smoke. Summary of the invention

[0007] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides an automatic smoke exhaust method, system and vehicle for vehicles, which can automatically detect smoking behavior and automatically turn on the vehicle-mounted smoke exhaust system.

[0012] When smoking behavior is detected, the vehicle's smoke exhaust system is turned on.

[0013] Furthermore, the high temperature area segmentation is performed by traversing each pixel of the thermal infrared image of the interior of the vehicle and determining the pixel with a temperature higher than a threshold as a high temperature area.

[0016] Furthermore, the exhaust duct is filled with a fragrance-making and smoke-eliminating agent containing acetic acid and an acid-base neutralization catalyst.

[0017] Furthermore, in the case of a vehicle-mounted smoke exhaust system, a thermal infrared image of the interior of the vehicle is acquired in real time, and the high-temperature area is segmented. When P consecutive thermal infrared images of the interior of the vehicle do not detect a high-temperature area, a delay of L minutes is made to turn off the smoking mode, where P and L are both set values.

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0033] Embodiment 1

[0034] This embodiment provides an automatic smoke exhaust method for a vehicle.

[0035] This embodiment provides an automatic smoke exhaust method for a vehicle, such as Figure 1 As shown, it includes the following steps

[0036] This embodiment provides an automatic smoke exhaust method for a vehicle, such as Figure 1 As shown, the following steps are included:

[0037] Step 1: A thermal infrared image acquisition device installed inside a vehicle acquires a thermal infrared image of the interior of the vehicle at the current moment.

[0038] The thermal infrared image acquisition device is installed on the top of the car to ensure that all areas in the car are covered, especially the driver and passenger seat areas. The device collects thermal infrared images at a speed of 30 frames per second to ensure real-time and continuity.

[0039] Step 2: Set a temperature threshold, traverse each pixel of the thermal infrared image of the interior of the vehicle at the current moment, and determine the pixel with a temperature higher than the threshold as a high temperature area.

[0040] The temperature threshold is set at 60°C, which is based on the typical temperature range of a burning cigarette. By traversing each pixel in the image, the system can quickly identify areas with abnormal temperatures and mark them as high-temperature areas.

[0041] Step 3: For the high temperature area, the first neural network is used to identify whether the high temperature area is a cigarette butt.

[0042] In this embodiment, the first neural network uses VGG16. Due to its deep structure, VGG16 can effectively extract image features at different levels; shallower layers tend to capture low-level features such as color and edges, and as the network depth increases, more complex morphological features are gradually learned, such as the local shape combination of objects; when processing feature extraction of a certain area in an image, VGG16 can extract rich color and morphological information from the pixel data of the area through the convolution operation of its convolutional layers.

[0043] In order to further improve the recognition accuracy, the VGG16 model used a large number of thermal infrared image data sets containing cigarette butts and other high-temperature objects (such as mosquito coils, lighters, etc.) during training to ensure that the model can accurately distinguish cigarette butts from other high-temperature objects.

[0044] Step 4: If the high-temperature area is detected as a cigarette butt, obtain several consecutive frames of thermal infrared images of the interior of the vehicle. For each frame of the thermal infrared image of the interior of the vehicle, use the method of step 2 to segment the high-temperature area and extract all pixel positions of the high-temperature area of ​​each frame of the thermal infrared image of the interior of the vehicle. Use the second neural network to identify whether there is smoking behavior.

[0045] In this embodiment, the first frame of a plurality of consecutive frames of thermal infrared images of the interior of a vehicle is a thermal infrared image of the interior of a vehicle in which a high temperature area is first identified and a cigarette butt is identified. That is, assuming that the thermal infrared image acquisition device acquires multiple images Xt-N, ..., Xt-2, Xt-1, Xt, where Xt is a thermal infrared image of the interior of a vehicle at the current moment, and N is a set value; if the thermal infrared image of the interior of a vehicle at the current moment identifies a high temperature area for the first time and a thermal infrared image of the interior of a vehicle in which the high temperature area is identified as a cigarette butt (that is, Xt-N, ..., Xt-2, Xt-1 all identify a high temperature area and a cigarette butt is identified as a thermal infrared image of the interior of a vehicle), then the thermal infrared image of the interior of a vehicle at the current moment is the first frame of a plurality of consecutive frames of thermal infrared images of the interior of a vehicle, and the plurality of consecutive frames of thermal infrared images of the interior of a vehicle are Xt, Xt+1, Xt+2, ..., Xt+M, and M is a set value.

[0046] The state of mosquito coils during the burning process is similar to that of cigarette butts. In order to avoid recognition errors in step 3, step 4 detects the movement trajectory of the cigarette butt to further confirm whether there is smoking behavior.

[0047] The second neural network uses an LSTM network. The sequence data input to the LSTM network is (Qt, Qt+1, Qt+2, …, Qt+M), where Qi is the position of all pixels in the high-temperature area of ​​a certain frame of thermal infrared image of the interior of the vehicle.

[0048] LSTM (Long Short-Term Memory Network) has excellent results in detecting the movement trajectory of cigarette butts due to its excellent ability to capture time dependencies in sequence data. By analyzing the position changes of cigarette butts in consecutive frames, the LSTM network can determine whether there is smoking behavior.

[0049] Step 5: When smoking behavior is detected, turn on the smoking mode.

[0050] In smoking mode, the vehicle needs to be powered on (high and low voltage), DC / DC works, the on-board HMI large screen works, and the on-board smoke exhaust system works.

[0051] like Figure 2 As shown, the vehicle-mounted smoke exhaust system is located on the roof directly above the driver, and includes an exhaust duct, an intake duct, an exhaust fan, and an air inlet hole arranged in the center of the exhaust fan.

[0052] Among them, the exhaust fan is a centrifugal exhaust fan. When the impeller of the exhaust fan rotates at a high speed driven by the motor, the air in the center area of ​​the impeller is driven by the blades to rotate together. Due to the action of centrifugal force, the air is thrown to the outer edge of the impeller, so that the air inlet hole in the center of the impeller forms a low-pressure area. Under the action of atmospheric pressure, the outside air is sucked into the air inlet hole in the center of the impeller through the air intake duct and enters the vehicle; the exhaust duct is in the shape of a volute, and the gas that is accelerated and thrown to the outer edge of the impeller enters the exhaust duct. The function of the exhaust duct is to collect the gas thrown out of the impeller and guide it to the outside of the vehicle.

[0053] The exhaust pipe is filled with a fragrance-making and smoke-eliminating agent mainly composed of acetic acid and an acid-base neutralization catalyst, which converts the smoke-odor gas into pollution-free gas outside the vehicle through a chemical reaction, thus blocking any connection with the interior of the vehicle.

[0054] In addition, the large screen can turn on the air purification mode to purify the odor in the car again and create a comfortable environment for other passengers in the cab.

[0055] Step 6. When the smoking mode is turned on, the thermal infrared image acquisition device installed inside the vehicle acquires thermal infrared images of the interior of the vehicle in real time, sets a temperature threshold, traverses each pixel of each thermal infrared image of the interior of the vehicle, and determines the pixel with a temperature higher than the threshold as a high-temperature area. When P consecutive thermal infrared images of the interior of the vehicle do not detect a high-temperature area, a delay of L minutes is made to turn off the smoking mode.

[0056] Among them, P and L are set values. P is set to 10 frames and L is set to 5 minutes to ensure that the system can turn off the smoking mode in time after the smoking behavior ends to avoid unnecessary energy consumption.

[0057] Step 7. The smoking mode can also be turned on and off directly through voice wake-up, mobile phone APP, large screen or ashtray shortcut button settings.

[0058] In this embodiment, a smoking relaxation mode is also provided, which can be turned on and off directly through voice wake-up, mobile phone APP, large screen or ashtray shortcut button setting. In the smoking relaxation mode, the vehicle needs to be powered on (high and low voltage), DC / DC working, on-board HMI large screen working, on-board smoke exhaust system working, music turned on, seat massage turned on, and windows closed to create a quiet and comfortable environment, so that users who are tired after a day can relax.

[0059] Step 8. Users can view images inside the car through the vehicle environment viewing function on the mobile phone APP, and can also manually turn on or off the smoking mode through the APP; users can use the voice button in the vehicle environment viewing interface of the mobile phone APP to communicate with the virtual character in the car, and can also use voice control to turn the smoking mode on or off.

[0060] In this embodiment, when the vehicle-mounted smoke exhaust system is working, the smoke sensor and alarm in the vehicle are turned on. If the driver accidentally drops unburned cigarette ash or cigarette butts into the vehicle, causing a combustion accident, the vehicle-mounted smoke alarm sends an alarm signal.

[0061] The automatic smoke exhaust method for a vehicle provided in this embodiment can automatically detect smoking behavior and automatically turn on the smoking mode. The simple and quick operation method greatly reflects the humanized and comfortable use experience.

[0062] The present embodiment provides an automatic smoke exhaust method for a vehicle, which exhausts and removes smoke through a vehicle-mounted smoke exhaust system without opening windows, and is suitable for use in rainy and snowy weather or when air conditioning is turned on in summer and winter.
