All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With the development of national high-speed network construction, particularly high-speed network construction in mountainous regions, many extra-long tunnels such as Qinling tunnels appear, and drivers are more prone to fatigue when driving in the tunnels for a long time than when driving in the normal outside, which leads to more easy accidents.

Therefore, the invention provides a tunnel lighting control method, which is applied to a tunnel lighting system, wherein the tunnel lighting system comprises a plurality of RGB (red, green and blue) lighting lamps, and the RGB lighting lamps are respectively arranged in each section of a tunnel.

Referring to fig. 1, in an embodiment of the present invention, a tunnel lighting control method includes:

s100, collecting the driving state of a driver and generating corresponding driver state information;

optionally, referring to fig. 2, in an embodiment of the present invention, the tunnel illumination system includes a plurality of image sensors, and step S100 includes:

step S110, shooting image information of a driver in driving;

in the embodiment, the tunnel lighting system is provided with a plurality of image sensors, such as cameras, and several groups of image sensors can be arranged in each tunnel segment at certain intervals, so as to ensure that the image of the driver is always shot by the image sensors in the process of the whole tunnel form.

Step S120, performing behavior and action recognition on the image information of the driver to generate corresponding driver state information;

the driver state information comprises driver eye movement information, driver breathing action information and driver head action information.

In the embodiment, the tunnel lighting system is provided with a central control component electrically connected with a plurality of image sensors, and the central control component can perform behavior and action recognition on the image information according to the received image information of the driver, wherein the behavior and action recognition comprises recognition of current eye movement information, breathing action information of the driver, head action information of the driver and the like. Alternatively, the driver eye movement information may be characterized by the eyelid movement information of the driver, such as the eye closing time, the eye opening time and the like, the driver breathing movement information may be characterized by the mouth movement information of the driver, such as the number of times of yawning of the driver is recognized and the like, and the driver head movement information may be characterized by the head swing frequency and the swing amplitude of the driver. The central control component can judge whether the driver is in a fatigue state according to the eye movement information, the breathing movement information and the head movement information of the driver, for example, the current driver is in a closed eye state for a long time, and then can judge that the current driver is in the fatigue state.

S200, collecting the driving state of a vehicle corresponding to a driver and generating corresponding vehicle driving state information;

optionally, referring to fig. 3, in an embodiment of the present invention, the tunnel lighting system includes a plurality of speed sensors, and step S200 includes:

step S210, detecting the driving speed of a vehicle corresponding to a driver and generating corresponding vehicle speed information;

in this embodiment, the speed sensors are all electrically connected to the central control component, and the tunnel lighting system is provided with a plurality of speed sensors, such as an ultrasonic tester and a microwave speed measuring instrument, which can also be integrated with the image sensor, so that the central control component measures the speed of the vehicle shot by the current image sensor in an image recognition manner, and can generate corresponding vehicle speed information according to the license plate number of each vehicle. The central control component can judge whether the driver of the current vehicle is in a fatigue state according to the vehicle speed information of each vehicle.

S220, shooting a driving route of a vehicle corresponding to a driver, and generating corresponding vehicle driving route information;

it should be understood that in the tunnel, since the overtaking is not allowed and the vehicle cannot change the lane, the vehicle will not shift too much during the normal running of the vehicle, and basically keeps running in a state of being parallel to the lane line on both sides and keeping the distance constant. Therefore, the central control component can also identify the distance between each vehicle and two lane boundaries of the current lane of each vehicle during driving according to the images of the vehicles shot by the image sensor. Specifically, since the driver may cause the steering wheel to be tilted when in a fatigue state, and the vehicle head may find an offset (left or right), the central control component may determine whether the driver is in the fatigue state according to the amount of change in the distance between the vehicle head of each recognized vehicle and the two lane boundaries of the lane where the vehicle is located, that is, the vehicle driving route information.

Wherein the vehicle driving state information includes vehicle speed information and vehicle driving route information.

In another embodiment, referring to fig. 4, in an embodiment of the present invention, step S200 further includes:

step S230, shooting the license plate number of the vehicle corresponding to the driver;

in the embodiment, the image sensor can also shoot the image information of the vehicle corresponding to the driver at the same time and transmit the image information to the central control component for image recognition, the central control component can also recognize the license plate number of each vehicle besides recognizing the vehicle speed information and the vehicle running route information in the embodiment, and correspondingly record the vehicle running state information and the driver state information of each vehicle in the memory in the central control component according to the license plate number.

And S240, searching the vehicle travel record of the vehicle corresponding to the driver in a preset time in a networking manner according to the license plate number of the vehicle corresponding to the driver, and generating corresponding vehicle running route information.

In this embodiment, the tunnel lighting system further includes a networking component, such as a wired communication component or a wireless communication component, and the networking component may be connected to an official traffic system, such as an intelligent traffic system, a skynet system, and the like. The central control component can upload the license plate number to the traffic system, so as to query the current vehicle and the travel record within the preset time in a networking manner, and generate corresponding vehicle running route information. In addition, the tunnel lighting system may further include a communication module, such as an ETC communication module, which reads a vehicle travel record of the current vehicle within a preset time by communicating with an ETC of the vehicle when the vehicle enters the tunnel, and generates corresponding vehicle travel route information. The central control component can judge whether the current driver is in a fatigue driving state or not according to the vehicle driving route information.

Step S300, detecting position information of a vehicle corresponding to a driver, and determining a tunnel subsection position where the vehicle corresponding to the driver is located;

step S400, when the driver is determined to be in the fatigue state according to the state information of the driver or the driving state information of the vehicle, controlling a plurality of RGB illuminating lamps at corresponding positions in a tunnel subsection where the vehicle corresponding to the driver is located to work according to a preset awakening strategy, wherein the preset awakening strategy comprises increasing the brightness of the lamp light, controlling the display of the awakening color of the lamp light and controlling the lamp light to flash at a preset frequency.

In this embodiment, the central control unit further determines the position of each vehicle, i.e., the location of the tunnel segment, according to the image information transmitted from the image sensors at different positions.

In this embodiment, the central control component is further electrically connected to the multiple RGB lighting lamps, and when determining that the driver is in a fatigue state according to the driver state information or the vehicle driving state information, the central control component may determine, according to the position information of the vehicle determined in the above embodiment, a tunnel segment where the vehicle corresponding to the driver in the current fatigue driving state is located, and control the multiple RGB lighting lamps in the corresponding positions in the corresponding tunnel segments to operate according to a preset wake-up policy, and does not change the operating states of the multiple RGB lighting lamps in other tunnel segments, and when the RGB lighting lamps in other tunnel segments do not detect the driver in the fatigue state in their tunnel segments, the central control component may operate according to normal lighting light to provide conventional lighting for the tunnel. It should be understood that, because the brightness of the light is increased in the wake-up strategy, the power consumption of the RGB lighting lamp is much higher than that of the RGB lighting lamp which emits light as normal lighting light when the RGB lighting lamp operates according to the preset wake-up strategy. Therefore, only the fatigue state driver is controlled to work according to the preset awakening strategy corresponding to the plurality of RGB illuminating lamps in the tunnel segment where the vehicle is located, and the power consumption of the illuminating system can be effectively reduced.

In addition, in this embodiment, in order to ensure that normal tunnel illumination in the tunnel segment is not affected and reduce the influence on the driver in the normal driving state, only a part of RGB illumination lamps in the tunnel segment may be controlled to operate according to a preset wake-up policy, other RGB illumination lamps are in the normal illumination operating state, for example, every 10 RGB illumination lamps are in one group, multiple groups of continuous RGB illumination lamps are provided in the tunnel segment, and when it is determined that the driver is in the fatigue state, the central control component only controls 7 illumination lamps therein to operate according to the preset wake-up policy. Therefore, illumination in the tunnel is guaranteed, the influence on a driver in a normal driving state is reduced, and meanwhile, the power consumption of a tunnel illumination system is reduced.

In this embodiment, the preset wake-up strategy includes increasing the brightness of the light, controlling the light to display the wake-up color, and controlling the light to flash at a preset frequency. Specifically, when determining that the driver is in a fatigue state according to the driver state information or the vehicle driving state information, the central control component controls the plurality of lighting RGB lamps of the tunnel segment where the abnormal vehicle corresponding to the fatigue state driver is located to increase the brightness, so as to increase the illumination intensity. Meanwhile, the central control component may control the plurality of illumination RGB lamps to display a wake-up color, such as blue or cyan (it is understood that a person is more easily awake when being illuminated with blue and cyan colors), and may control the plurality of illumination RGB lamps to always display one wake-up color, and may also control the plurality of illumination RGB lamps to switch between a plurality of wake-up colors, such as blue 5S, cyan 5S, and the like. Meanwhile, the plurality of lighting RGB lamps are controlled to flash at a preset frequency, for example, flashing is carried out once every 2S, or the plurality of lighting RGB lamps can also flash in the form of water flow lamps and gradual change lamps, so that the stimulation of the social and livestock lighting is further improved. Therefore, when the driver in the tunnel is in a fatigue state, the plurality of RGB illuminating lamps in the tunnel segment where the vehicle corresponding to the driver in the fatigue state is located can be controlled to work according to the preset awakening strategy in time, so that the driver in the fatigue state is stimulated and awakened, and the driving safety of the vehicle in the tunnel is effectively improved.

Optionally, referring to fig. 5 to 6, in an embodiment of the present invention, step S400 includes:

step S410, according to the eye movement information of the driver, when the eye closing time of the driver is determined to be larger than the preset eye closing time, judging that the driver is in a fatigue state;

in this embodiment, after recognizing the current eye movement information, the central control component starts to count time when the driver is in the eye-closing state, so as to record the time when the driver closes the eyes. It can be understood that a driver in a normal waking state will generally close the eyes only during a blinking motion, and the time is short, generally between 0.1S and 0.3S. However, if the driver is currently in a state of fatigue driving, the driver may be in a half-sleep and half-awake state due to the difficulty of the driver, resulting in a long-time eye closure. Therefore, if the eye closing time of the driver is detected to be greater than or equal to the preset eye closing time. The preset eye closing time is tested by research personnel in the research and development process and is pre-stored in a central control component, for example, the current preset eye closing time is 1.5S, and if the time for closing the eyes of the driver any time is detected to be greater than 1.5S, the driver is determined to be in a fatigue state.

Step S420, according to the breathing action information of the driver, when the yawning times of the driver reach the preset yawning times within the preset time, judging that the driver is in a fatigue state;

it can be understood that when a driver is in fatigue driving, frequent sleepiness can be caused, resulting in yawning for a plurality of times within a certain time. In this embodiment, the central control component may identify the yawning action of the driver according to the current breathing action information of the driver, and if the yawning times of the driver within the preset time reaches the preset yawning times (where the preset time and the preset yawning times are preset in the central control component by the research and development staff). It can be judged that the driver is currently in a fatigue state. Further, in another embodiment, it is appreciated that the time between yawns for a driver in a tired state is short. Therefore, the central control component can also determine that the current driver is in the fatigue state by calculating the time between two yawns of the driver and when the frequency that the time between the two yawns is found to be less than the preset yawns interval time reaches a certain preset frequency.

Step S430, according to the head action information of the driver, when the head swing frequency of the driver reaches the preset swing frequency or the head swing distance of the driver reaches the preset swing distance, judging that the driver is in a fatigue state;

it can be understood that when the driver is in fatigue state, the driver's consciousness is blurred due to the sleepiness, and the sudden sleeping and the sudden waking up are repeated, however, when the driver falls asleep suddenly, the head of the driver naturally sags, and when the driver wakes up, the driver swings back to the normal position. Therefore, in this embodiment, the central control component further determines that the driver is currently in the fatigue state when determining that the head swing frequency of the driver reaches the preset swing frequency or when determining that the head swing distance of the driver reaches the preset swing distance according to the head motion information. The preset swing frequency and the preset swing distance can be obtained by research personnel according to multiple tests and are prestored in the central control assembly.

Step S440, according to the vehicle speed information, when the vehicle speed change rate of the vehicle corresponding to the driver is determined to be larger than a preset speed change rate, judging that the driver is in a fatigue state;

it is understood that when the driver is just tired, the driver does not go to sleep completely, but goes to half-sleep and half-awake, and the driver is suddenly asleep for a short time and wakes up again suddenly. When a driver suddenly falls asleep, the foot originally stepping on the accelerator may be slightly loosened, if the vehicle does not start cruise at a constant speed or the current vehicle model is older and does not have the cruise control function, the speed of the vehicle is suddenly slowed down, and when the driver suddenly wakes up, the driver habitually steps on the accelerator again, and the vehicle is suddenly slowed down during the driving process. However, in normal tunnel driving, the vehicle speed is generally kept constant. Therefore, in this embodiment, the central control component may determine that the driver is in a fatigue state currently when the number of times of the fast and slow changes of the vehicle speed of the running vehicle within the preset vehicle speed change time is found to be greater than the preset speed change number according to the vehicle speed information. The speed change of the vehicle is characterized in that the speed of the vehicle is increased after being reduced, and each time the speed change of the vehicle is the speed of the vehicle is accelerated after being decelerated once. Meanwhile, it can be understood that the vehicle speed fluctuates and changes between speeds when the vehicle is normally running, so that the vehicle speed with the vehicle speed of more than 5Km/H is changed as a speed change. For example, when the current vehicle speed is changed from 60Km/H to 54Km/H and from 54Km/H to 62Km/H, a change in speed is calculated. The preset vehicle speed change time and the preset speed change times are obtained by a research and development worker through multiple tests and are prestored in the central control assembly.

Step S450, according to the vehicle running route information, when the fact that the running route offset distance of the vehicle corresponding to the driver is larger than the preset offset distance is determined, the driver is judged to be in a fatigue state;

it is understood that when the driver is just tired, the driver does not go to sleep completely, but goes to half-sleep and half-awake, and the driver is suddenly asleep for a short time and wakes up again suddenly. When the driver is asleep suddenly, the hands are in a natural relaxed state, the steering wheel may not be held, and the steering wheel is slightly deflected along with the relaxation action of the hands, so that the vehicle is deflected. According to the regulations of traffic laws, overtaking is not allowed in the tunnel, so that the distance between the head of the vehicle and the lane boundary between the two sides does not change greatly in the general condition. Therefore, the central control component can judge that the driver is in a fatigue state when the vehicle running offset distance is found to be greater than the preset offset distance according to the current vehicle running route information, namely when the change value of the distance between the head of the current vehicle and the lane boundary lines on the two sides is greater than the preset offset distance.

Step S460, according to the vehicle running information, when the time for the driver to continuously drive is determined to reach the preset continuous driving time, judging that the driver is in a fatigue state;

it is to be understood that in practice, long driving tends to be the greatest cause of fatigue driving. Therefore, in the embodiment, after acquiring the license plate number of the vehicle, the central control component may be networked with a police system, such as an skynet system, through the networking component, so as to call out the driving route information of the vehicle within a preset time, for example, within four hours, and if the vehicle is found to be in a driving state all the time according to the driving information within four hours, it is determined that the driver is in a fatigue state. The driving state comprises a constant driving state or a condition that any one single stay time is less than half an hour in the middle.

Step 470, when the driver is determined to be in the fatigue state, controlling the plurality of RGB illumination lamps corresponding to the vehicle in the tunnel segment to operate according to a preset wake-up strategy, where the preset wake-up strategy includes increasing the brightness of the light, controlling the light to display the wake-up color, and controlling the light to flash at a preset frequency.

In this embodiment, the central control component may determine the mental state of the driver according to the above six steps, and only when the drivers are determined not to be in the fatigue state in the determination process of the above six steps, the central control component may finally confirm that the current driver is in the awake driving state. If any one of the RGB illuminating lamps judges that the current driver is in the fatigue state, the central control component controls the RGB illuminating lamps at the corresponding positions in the tunnel segment where the vehicle corresponding to the driver in the fatigue state is located to work according to a preset awakening strategy. Through foretell multi-angle judgement, can effectual improvement judge whether the driver is in the accuracy nature of fatigue state to the condition of detection omission appears in preventing, further improvement the security that the vehicle went in the tunnel.

According to the technical scheme, the driving state of a driver is collected firstly, and corresponding driver state information is generated; meanwhile, the driving state of the vehicle corresponding to the driver is collected, and corresponding vehicle driving state information is generated; detecting the position information of the vehicle corresponding to the driver, and determining the tunnel section where the vehicle corresponding to the driver is located; and finally, when the driver is determined to be in a fatigue state according to the state information of the driver or the driving state information of the vehicle, controlling a plurality of RGB illuminating lamps corresponding to the position in the tunnel segment where the vehicle is located to work according to a preset awakening strategy, wherein the preset awakening strategy comprises increasing the brightness of the lamp light, controlling the lamp light to display awakening colors and controlling the lamp light to flicker at a preset frequency. Therefore, when the driver in the tunnel is in a fatigue state, the plurality of RGB illuminating lamps in the tunnel segment where the vehicle corresponding to the driver in the fatigue state is located can be controlled to work according to the preset awakening strategy in time, so that the driver in the fatigue state is stimulated and awakened, and the driving safety of the vehicle in the tunnel is effectively improved. Meanwhile, only a plurality of RGB illuminating lamps in the tunnel section where the vehicle corresponding to the driver in the fatigue state is located are controlled to work according to a preset awakening strategy, so that the power consumption of the tunnel illumination system is effectively reduced, and the energy conservation of the tunnel illumination system is improved.

Referring to fig. 7, in an embodiment of the present invention, the tunnel lighting system further includes a plurality of searchlights and a plurality of driving assemblies in driving connection with the searchlights in a one-to-one correspondence, the plurality of searchlights are respectively disposed in each segment of the tunnel, and the tunnel lighting control method further includes:

and step S500, when the driver is confirmed to be in a fatigue state, driving the searchlight to follow the vehicle corresponding to the irradiation fatigue driver so as to prompt the surrounding vehicle to keep a distance with the vehicle.

It will be appreciated that the brightness of the RGB illumination lamps in each tunnel segment cannot be too bright in order to ensure normal lighting requirements within each tunnel segment and not affect the driver in a normally driving vehicle. Meanwhile, a driver in a fatigue state can not wake up from the fatigue state every time, and at the moment, the vehicle is possibly in an abnormal driving state, and the vehicle which does not know about to normally drive around can collide with the vehicle which does not normally drive because of too late dodging to cause an accident.

Therefore, in the embodiment, a plurality of searchlights and driving assemblies in one-to-one driving connection with the searchlights are further arranged in each tunnel segment at certain intervals, and the searchlights can be arranged at the top end of the tunnel wall, so that the emitted light beams can follow and irradiate the fatigue state driver, the front vision of the fatigue state driver cannot be influenced, the front vision of other drivers of vehicles running normally cannot be influenced, and the light beams cannot directly penetrate into the eyes of the drivers to cause dazzling of the drivers. The present drive assembly may comprise a plurality of motors so as to be able to control the swinging movement in a fore-and-aft direction and a left-and-right direction vertically suspended from the top end of the tunnel wall.

In this embodiment, when it is determined that a driver in a fatigue state currently occurs in a certain tunnel segment, the central control component in the tunnel lighting system controls the searchlight at the corresponding position to be turned on according to the captured image information of the driver, and controls the driving component to drive the searchlight to emit the light beam to continuously follow the driver in the fatigue state, so that the driver in the fatigue state is stimulated more strongly by the high-brightness searchlight light, and the driver is awakened more effectively, and the driver is enabled to resume a normal waking state. Meanwhile, the light beam emitted by the searchlight can remind surrounding vehicles, and it is understood that the searchlight is hung at the top end of the tunnel wall, so that not only the vehicle corresponding to a fatigue state driver can know that the driver of the vehicle is in a fatigue state (the vehicle is in an abnormal state), but also vehicles which are separated by a plurality of vehicles in the same tunnel segment can know that the driver of the vehicle in front is in a fatigue driving state. At the moment, after the vehicles running normally around see the abnormal vehicles irradiated by the searchlight, the vehicles can actively keep a certain distance with the abnormal vehicles and focus more on driving attention, so that if the abnormal vehicles are out of control, the vehicles around can be avoided in time, and the safety of the vehicles running normally around is ensured.

Further, in another embodiment, referring to fig. 8, the tunnel illumination control method further includes:

step S510, determining the fatigue degree of the driver according to the judgment result of the step S410-the step S460;

in the present embodiment, the central control component determines the fatigue degree of the driver according to the determination results in the steps S410 to S460. For example, according to the detection condition, determining that the driver meets the judgment condition of the fatigue state in two or less steps, for example, if the eye closing time is longer than the preset eye closing time and the yawning times reach the preset yawning book within the preset time, determining that the fatigue degree of the driver is light fatigue; if the driver is determined to meet the determination conditions of the fatigue states in the three to four steps, determining that the fatigue degree of the driver is moderate fatigue; if it is determined that the driver satisfies the determination conditions of the fatigue state in five to six steps, it is determined that the degree of fatigue of the driver is severe fatigue.

And S520, adjusting the lighting parameters of the searchlight according to the fatigue degree.

In this embodiment, a developer may preset a fatigue level-searchlight illumination parameter mapping table in the central control component, and the central control component may adjust the illumination parameter of the searchlight according to the determination results of the steps S410 to S460. Optionally, the lighting parameters may include a searchlight light-out color temperature, a searchlight light-out saturation and a searchlight light-out brightness, and the light-out saturation and the brightness of the searchlight may be respectively provided with three gears corresponding to the fatigue degree. For example, if it is determined that the fatigue degree of the driver currently in the fatigue state is severe fatigue, the central control component controls the light-emitting color temperature of the current searchlight to be blue, and increases the brightness and the saturation to a third gear (i.e. preset maximum brightness and maximum saturation), so as to enhance the stimulation effect of a light column emitted by the searchlight, further improve the stimulation effect on the driver in the fatigue state, and thus more quickly awaken the driver from the fatigue state. Meanwhile, it is to be understood that the power of the searchlight is often large, so that the lighting parameters of the searchlight are adjusted according to the current fatigue level, the total power consumption of the tunnel lighting system can be reduced, and the energy saving performance of the tunnel lighting system is improved.

The invention also provides a tunnel lighting system which comprises a central control assembly, a power supply assembly, a networking assembly, a plurality of RGB (red, green and blue) lighting lamps, a plurality of image sensors, a plurality of speed sensors, a plurality of searchlights, a plurality of driving assemblies in one-to-one corresponding driving connection with the searchlights, and a tunnel lighting control method. The central control component comprises a memory and a processor, the memory stores a tunnel lighting control program, and the tunnel lighting control program realizes the tunnel lighting control method according to any one of the above items when being executed by the processor.

The RGB illuminating lamps are respectively arranged in each section of the tunnel; the central control assembly is respectively electrically connected with the networking assembly, the plurality of RGB illuminating lamps, the plurality of image sensors, the plurality of speed sensors, the plurality of driving assemblies and the plurality of searchlights, and the power supply assembly is respectively electrically connected with the central control assembly, the networking assembly, the plurality of RGB illuminating lamps, the plurality of image sensors, the plurality of speed sensors, the plurality of searchlights and the plurality of driving assemblies.

In the present embodiment, the tunnel interior is divided into a plurality of tunnel segments, each of which is provided with a plurality of RGB illumination lamps, a plurality of image sensors, a plurality of speed sensors, a plurality of illumination lamps, and a plurality of driving components for driving the searchlight, respectively. When a driver in a fatigue state is detected in a certain tunnel segment, only the part of the plurality of RGB illuminating lamps in the tunnel segment where the driver is located is controlled to work according to a preset awakening strategy, the working states of the plurality of RGB illuminating lamps in other tunnel segments are not changed, and when the driver in the fatigue state is not detected in the tunnel segment of the RGB illuminating lamps in other tunnel segments, the RGB illuminating lamps in other tunnel segments can work according to normal illuminating light to provide conventional illumination for the tunnel. It should be understood that, because the brightness of the light is increased in the wake-up strategy, the power consumption of the RGB lighting lamp is much higher than that of the RGB lighting lamp which emits light as normal lighting light when the RGB lighting lamp operates according to the preset wake-up strategy. Therefore, the power consumption of the tunnel lighting system can be effectively reduced, and the energy saving performance of the tunnel lighting system is improved.

In the embodiment, one or more image sensors, one or more speed sensors, one or more searchlights and a plurality of driving components in driving connection with the searchlights are arranged in each tunnel segment at intervals, so that the vehicles can be always in the detection range of the sensors and the irradiation range of the searchlights in the tunnel.
