Description

Technical Field

[0001] This utility model relates to the field of vehicle control technology, and in particular to a dangerous driving identification device. Background Technology

[0002] With the acceleration of urbanization and the increase in population density, taxis, as an important mode of public transportation, play an indispensable role in people's daily travel. However, due to the special nature of taxi work (such as long driving hours and nighttime operation), drivers are prone to dangerous driving behaviors such as fatigued driving or drunk driving, which not only threatens the safety of the drivers themselves, but also poses a serious threat to the lives and property of passengers and other road users.

[0003] Despite strict laws and regulations against drunk driving and driving while fatigued in various countries, drunk driving persists due to some drivers' weak legal awareness or a sense of impunity. Some taxi drivers may continue working after drinking outside of work hours without sufficient rest, leading to excessive blood alcohol levels in the vehicle or sleep deprivation, increasing the risk of traffic accidents.

[0004] Existing alcohol testing methods (such as handheld breathalyzers) usually require human intervention, and traditional methods for detecting fatigued driving mainly rely on human observation (such as judging by facial expressions). Neither of these methods can achieve automation and real-time monitoring, making it difficult to detect and deal with safety hazards in advance. Utility Model Content

[0016] The main control module is used to output a parking control signal to the vehicle control system when it detects that the driver is fatigued / the alcohol concentration in the vehicle is greater than the alcohol concentration threshold, and the vehicle is in a parked or idling state according to the vehicle status signal, so that the vehicle control system can prevent the vehicle from moving; it also outputs a hazard light control signal to the vehicle control system so that the vehicle control system can control the vehicle's hazard lights to flash.

[0021] The main control module is also used to control the voice module to play a second preset voice message when it is detected that the driver is not fatigued and the alcohol concentration in the vehicle is less than or equal to the alcohol concentration threshold, so as to remind passengers that the driver is not fatigued or drunk driving.

[0022] In one embodiment, the dangerous driving identification device further includes:

[0023] A timer is electrically connected to the main control module, which is electrically connected to the vehicle control system. The vehicle control system is used to send corresponding vehicle status signals according to the vehicle's status.

[0026] In one embodiment, the dangerous driving identification device further includes:

[0027] The display module is electrically connected to the main control module.

The main control module, when detecting driver fatigue based on the facial image signal and / or detecting an alcohol concentration in the vehicle's interior exceeding a threshold based on the alcohol concentration signal, sends a corresponding alarm signal to the external terminal via the wireless communication module to alert the driver to fatigued or intoxicated driving. With this configuration, in practical applications, taxi companies can install this dangerous driving identification device in taxis to monitor in real time whether the driver is fatigued or intoxicated. When the driver is found to be fatigued or intoxicated, the device sends an alarm signal to the taxi company's monitoring center, enabling monitoring personnel to promptly detect the driver's fatigue or intoxication and take appropriate measures to prevent safety hazards.

[0044] With the acceleration of urbanization and the increase in population density, taxis, as an important mode of public transportation, play an indispensable role in people's daily travel. However, due to the special nature of taxi work (such as long driving hours and nighttime operation), drivers are prone to dangerous driving behaviors such as fatigued driving or drunk driving, which not only threatens the safety of the drivers themselves, but also poses a serious threat to the lives and property of passengers and other road users.

[0045] Despite strict laws and regulations against drunk driving and driving while fatigued in various countries, drunk driving persists due to some drivers' weak legal awareness or a sense of impunity. Some taxi drivers may continue working after drinking outside of work hours without sufficient rest, leading to excessive blood alcohol levels in the vehicle or sleep deprivation, increasing the risk of traffic accidents.

[0046] Existing alcohol testing methods (such as handheld breathalyzers) usually require human intervention, and traditional methods for detecting fatigued driving mainly rely on human observation (such as judging by facial expressions). Neither of these methods can achieve automation and real-time monitoring, making it difficult to detect and deal with safety hazards in advance.

[0047] Therefore, this utility model proposes a dangerous driving identification device, aiming to solve the technical problem that existing technologies cannot monitor in real time whether a driver is driving while fatigued or under the influence of alcohol. In one embodiment of this utility model, referring to... Figure 1 Dangerous driving detection devices include:

[0048] Image recognition module 10, which is used to acquire the driver's face image and output the corresponding face image signal;

[0049] An alcohol concentration detection module 20 is used to detect the alcohol concentration in the vehicle interior and output a corresponding alcohol concentration signal.

[0050] Wireless communication module 30, the wireless communication module 30 is used to establish a wireless communication connection with an external terminal;

[0051] The main control module 40 is electrically connected to the image recognition module 10, the alcohol concentration detection module 20, and the wireless communication module 30, respectively.

[0052] The main control module 40 is used to send a corresponding alarm signal to an external terminal via the wireless communication module 30 when the driver is detected to be in a state of fatigue based on the facial image signal, and / or when the alcohol concentration in the vehicle environment is detected to be greater than the alcohol concentration threshold based on the alcohol concentration signal, so as to remind the driver that he is in a state of fatigued driving / drunk driving.

[0053] In this embodiment, the present invention can refer to the published patent CN119649547A, "Fatigue Driving Detection System Based on Image Recognition," to identify fatigue driving. The specific process is as follows: When the main control module 40 receives a face image signal, it can use face region image extraction to calculate the percentage of eye closure time and mouth opening time per unit time. Using the percentage of eye closure time and mouth opening time per unit time, the current driver's fatigue level is obtained. When the driver's fatigue level is greater than the fatigue level threshold, it is determined that the driver is in a state of fatigue driving.

[0054] In this embodiment, optionally, the alcohol concentration detection module 20 can be implemented using a light-emitting component 21 and a spectral acquisition component 22, as shown in the reference. Figure 2 The light-emitting component 21 and the spectral acquisition component 22 are electrically connected to the main control module 40 respectively. The light-emitting component 21 is used to emit a light signal of a preset wavelength to the driver's face, and the spectral acquisition component 22 is used to acquire the driver's facial spectrum and output the corresponding spectral image signal.

[0055] The main control module 40 is used to send a corresponding alarm signal to an external terminal via the wireless communication module 30 when the alcohol concentration around the driver is detected to be greater than the alcohol concentration threshold based on the spectral image signal.

[0056] The main control module 40 stores a mapping table between spectral images and blood alcohol concentrations. The main control module 40 compares the acquired spectral image with the mapping table. If the acquired spectral image matches the intoxication spectral image database, it can be confirmed that the driver is currently driving under the influence of alcohol. In this case, the main control module 40 uses the vehicle control system 50 to stop the car's engine, preventing the driver from starting the car. If the acquired spectral image does not match the intoxication spectral image database, it can be confirmed that the driver is not driving under the influence of alcohol.

[0057] It should be noted that during the research and development process, researchers will emit light signals of the aforementioned preset wavelengths to test subjects with different blood alcohol concentrations (blood alcohol concentration greater than or equal to the legal limit for drunk driving) and collect spectral images of the driver's face in order to obtain multiple intoxication spectral images and their corresponding blood alcohol concentrations, which will then be mapped in a spectral image-blood alcohol concentration mapping table.

[0058] Optionally, the alcohol concentration detection module 20 can also be implemented using an alcohol concentration sensor. The alcohol concentration sensor detects the alcohol concentration based on the principle of redox reaction. When alcohol molecules come into contact with the surface of the alcohol concentration sensor, a chemical reaction occurs and a current signal is generated. The alcohol concentration sensor determines the alcohol concentration based on the magnitude of the current signal.

[0059] In this embodiment, the main control module 40 can be implemented using MCU (Microcontroller Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), SOC (System On Chip), etc.

[0060] In this embodiment, the wireless communication module 30 can be implemented using technologies such as 4G / 5G, Wi-Fi, NB-IoT, and LoRa. By establishing a communication connection with a cloud platform or monitoring center, it can transmit alarm signals and sensor data to a remote terminal in real time.

[0061] This utility model's dangerous driving identification device includes an image recognition module 10, which acquires the driver's facial image and outputs a corresponding facial image signal; an alcohol concentration detection module 20, which detects the alcohol concentration in the vehicle's interior and outputs a corresponding alcohol concentration signal; a wireless communication module 30, which establishes a wireless communication connection with an external terminal; and a main control module 40, which is electrically connected to the image recognition module 10, the alcohol concentration detection module 20, and the wireless communication module 30. The main control module 40, when detecting driver fatigue based on the facial image signal and / or detecting an alcohol concentration in the vehicle's interior exceeding a threshold based on the alcohol concentration signal, sends a corresponding alarm signal to an external terminal via the wireless communication module 30 to alert the driver to fatigued driving / drunk driving. With this setup, in practical applications, taxi companies can install the dangerous driving identification device of this utility model in taxis to monitor in real time whether the driver is driving while fatigued or under the influence of alcohol. When the driver is driving while fatigued or under the influence of alcohol, the dangerous driving identification device of this utility model sends an alarm signal to the monitoring center of the taxi company, so that the monitoring personnel can promptly detect the driver's fatigued or under the influence of alcohol and take corresponding measures to avoid safety hazards.

[0062] In one embodiment of this utility model, reference is made to Figure 3 The main control module 40 is also electrically connected to the vehicle control system 50, which is used to send corresponding vehicle status signals according to the vehicle status.

[0063] The main control module 40 is used to output a parking control signal to the vehicle control system 50 when it detects that the driver is fatigued / the alcohol concentration in the vehicle is greater than the alcohol concentration threshold, and the vehicle is in a parked or idling state according to the vehicle status signal, so that the vehicle control system 50 controls the vehicle to be unable to move; it also outputs a hazard light control signal to the vehicle control system 50 so that the vehicle control system 50 controls the vehicle's hazard lights to flash.

[0064] In this embodiment, the main control module 40 establishes communication with the vehicle control system 50 through a standardized interface (such as CAN bus, LIN bus or dedicated I / O interface), and the vehicle status includes parking status, idling status and driving status.

[0065] With this setup, in practical applications, when a driver gets into the vehicle and starts it, the vehicle must be identified by the dangerous driving identification device of this invention. If the device detects that the driver is driving while fatigued or under the influence of alcohol, it outputs vehicle control signals and hazard light control signals to the vehicle control system 50. This ensures that the vehicle control system 50 maintains the current state when the vehicle is parked, preventing restarting, or controls the engine to shut off or restricts vehicle movement when the vehicle is idling, thus preventing the vehicle from moving and avoiding accidents caused by driver fatigue or under the influence of alcohol. The vehicle control system 50 also controls the vehicle's hazard lights to flash when it receives the hazard light control signal to warn surrounding vehicles and pedestrians.

[0066] This invention, through its linkage with the vehicle control system 50, enables automated intervention (such as stopping and hazard light warning) when dangerous driving behavior is detected. This design not only effectively improves driving safety but also reduces the need for human intervention, providing strong technical support for safety management in the taxi industry.

[0067] It is important to consider that when a driver is fatigued or intoxicated while driving, stopping the vehicle could lead to rear-end collisions as other vehicles may not have enough time to react, or a sudden stop could cause traffic congestion and affect the passage of other vehicles.

[0068] In one embodiment, reference is made to... Figure 4 The dangerous driving identification device further includes:

[0069] The positioning module 60 is electrically connected to the main control module 40. The main control module 40 is used to send the positioning information sent by the positioning module 60 to an external terminal via the wireless communication module 30 when it detects that the driver is fatigued / the alcohol concentration in the vehicle is greater than the alcohol concentration threshold, and the vehicle is in motion according to the vehicle status signal.

[0070] With this configuration, when the dangerous driving identification device of this utility model detects driver fatigue or drunk driving, it will not directly control the vehicle to slow down or stop. Instead, it will send the location information to an external terminal, avoiding the risk of secondary accidents caused by sudden stopping or forced deceleration. The monitoring center can quickly locate the vehicle's position through the location information and determine whether it is in a high-risk area (such as a highway or urban main road), or dispatch nearby management personnel or law enforcement vehicles to the scene to handle the situation and stop dangerous driving behavior in a timely manner.

[0071] In one embodiment of this utility model, reference is made to Figure 5 The dangerous driving identification device further includes:

[0072] The voice module 70 is electrically connected to the main control module 40. The main control module 40 is used to control the voice module 70 to play a first preset voice message when it detects that the driver is fatigued and / or detects that the alcohol concentration in the vehicle is greater than the alcohol concentration threshold, so as to remind the passenger that the driver is fatigued or drunk driving.

[0073] The main control module 40 is also used to control the voice module 70 to play a second preset voice message when it is detected that the driver is not fatigued and the alcohol concentration in the vehicle is less than or equal to the alcohol concentration threshold, so as to remind passengers that the driver is not fatigued or drunk driving.

[0074] In this embodiment, when the system detects that the driver is fatigued or driving under the influence of alcohol, the voice module 70 will play a first preset voice message, such as "Dear passenger, the system has detected that the driver may be driving while fatigued or under the influence of alcohol. Please get off the vehicle immediately to avoid any accidents," to inform the passenger of the potential safety hazard. When the system detects that the driver is not fatigued and the blood alcohol concentration is below the threshold, the voice module 70 will play a second preset voice message, such as "Dear passenger, the system has detected that the driver is in good condition. Please feel free to ride with us and have a pleasant journey!" to inform the passenger that the driver is in good condition.

[0075] With this configuration, the dangerous driving identification device of this utility model, by introducing a voice module 70 and playing preset voice prompts in different situations, can effectively enhance passengers' right to know the driver's status and promptly remind passengers to take appropriate measures when dangerous driving behavior occurs, so as to avoid safety hazards.

[0076] Furthermore, this utility model's dangerous driving detection device can not only provide voice prompts to passengers, but also provide prompts through the display module 80. In another embodiment, refer to... Figure 6 The dangerous driving identification device further includes:

[0077] Display module 80, which is electrically connected to main control module 40; main control module 40 is used to control display module 80 to display a first preset text prompt, such as "Warning! The driver may be driving while fatigued or under the influence of alcohol, please pay attention to safety.", when it detects that the driver is fatigued or under the influence of alcohol in the vehicle and / or when it detects that the alcohol concentration in the vehicle is greater than the alcohol concentration threshold, so as to remind passengers that the driver is driving while fatigued or under the influence of alcohol.

[0078] The main control module 40 is also used to control the display module 80 to display a second preset text prompt, such as "The driver is in normal condition, please feel free to ride, and have a pleasant journey!", when it is detected that the driver is not fatigued and the alcohol concentration in the vehicle is less than or equal to the alcohol concentration threshold, so as to remind passengers that the driver is not fatigued or drunk driving.

[0079] Furthermore, the voice module 70 can be used not only to prompt passengers but also to alert the driver to fatigue. In one embodiment, referencing Figure 7 The dangerous driving identification device further includes:

[0080] A timer 90 is electrically connected to the main control module 40, which is electrically connected to the vehicle control system 50. The vehicle control system 50 is used to send corresponding vehicle status signals according to the vehicle's status.

[0081] The main control module 40 is used to control the timer 90 to start timing when the vehicle status signal detects that the vehicle is in a driving state.

[0082] The main control module 40 is used to control the voice module 70 to play a third preset voice message when the timer 90 reaches a preset duration, in order to remind the driver that the driving time has been too long.

[0083] With this setup, in practical applications, when a driver drives continuously for more than a certain period of time (such as 4 hours), the dangerous driving recognition device of this utility model will play a third preset voice message, such as "Please note! You have been driving continuously for a long time. It is recommended that you pull over and rest as soon as possible to avoid fatigue driving." This serves as a reminder to the driver that the driving time has been too long, thereby effectively preventing the problem of fatigue driving.

[0084] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
