Description

Technical Field

[0001] The present invention relates to the field of highway tunnels, and in particular to a highway tunnel entrance early warning system and method. Background Art

[0002] According to statistics, the number of traffic accidents in tunnel sections accounts for 36.5% of the total number of highway accidents. Among them, the tunnel entrance and exit sections are the most prone to accidents, and the traffic accident rate is 23 times that of the tunnel interior.

[0003] When the driver enters the tunnel, there is a large difference in brightness inside and outside the tunnel, and the human eye has limited ability to adapt to sudden changes in light intensity. When driving into the tunnel, it is easy to produce a "black hole effect", and no external information can be received in a short period of time, which leads to the highest probability of accidents at the entrance of the tunnel. In order to reduce the incidence of traffic accidents and reduce casualties, the existing safety control measures for the entrance of highway tunnels include speed control, lane control, video capture and light environment optimization. In terms of speed control, horizontal or vertical deceleration markings are set at appropriate positions in front of the tunnel entrance to remind drivers to slow down and drive safely according to speed limit requirements. In terms of lane control, a dividing line prohibiting crossing the same-direction lane is set 150m outside the tunnel at the entrance of the tunnel. In terms of video capture, the effect of limiting drivers from speeding and changing lanes can be achieved by capturing illegal behaviors through video; and in terms of light environment optimization, by balancing the difference in light intensity inside and outside, the adverse visual effects when entering and exiting the tunnel can be eliminated or weakened.

[0004] These safety control measures are all aimed at warning drivers to slow down and stay in the lane at the tunnel entrance. This indiscriminate warning to all drivers, coupled with the fact that such safety control measures are also generally installed on other roads or at tunnel entrances, causes drivers to become tired of such safety control measures. Therefore, although there is a certain effect in reducing traffic accidents, the effect is not obvious. Summary of the invention

[0005] One object of the present invention is to provide a highway tunnel entrance warning system and method, which detects environmental data information of the tunnel entrance by setting up a warning column at the tunnel entrance, and adjusts the lighting brightness and color temperature of the tunnel entrance, so as to actually improve the safety control of the tunnel entrance when vehicles pass through the tunnel.

[0006] This purpose is achieved by adopting the following technical solutions:

[0007] A highway tunnel entrance warning system and method, comprising a warning column arranged at the tunnel entrance, wherein a first environmental data acquisition component, a lighting component and a data processing component are arranged on the warning column; the lighting component comprises a plurality of lighting lamps; the first environmental data acquisition component is used to detect environmental data information of the tunnel entrance, wherein the environmental data information comprises PM2.5 data information; the data processing component is used to obtain visibility information of the tunnel entrance according to the environmental data information; the lighting component is used to adjust the lighting brightness and color temperature of the plurality of lighting lamps at the tunnel entrance according to the visibility information of the tunnel entrance; when the PM2.5 data information is greater than or equal to a first preset value, the data processing component obtains the visibility information of the tunnel entrance as poor visibility; when the visibility information is When visibility is poor, the lighting brightness of several lamps at the tunnel entrance is 3000-5000 lux, and the color temperature is warm light; when the PM2.5 data information is less than the first preset value and greater than or equal to the second preset value, the data processing component obtains the visibility information of the tunnel entrance as medium visibility; when the visibility information is medium visibility, the lighting brightness of several lamps at the tunnel entrance is 2000-3000 lux, and the color temperature is warm light; when the PM2.5 data information is less than the second preset value, the data processing component obtains the visibility information of the tunnel entrance as good visibility; when the visibility information is good visibility, the lighting brightness of several lamps at the tunnel entrance is 500-2000 lux, and the color temperature is cold light.

[0008] When visibility is poor or moderate, the lighting brightness at the tunnel entrance is further increased to improve the visibility of the driver at the tunnel entrance. A higher light intensity of 3000-5000 lux can provide sufficient lighting to ensure that the driver can clearly see the situation at the tunnel entrance. The light intensity is usually between 2000-3000 lux, which can provide a clear and comfortable view for the driver. A lighting brightness of 500-2000 lux can ensure sufficient lighting while avoiding overstimulation.

[0009] In low visibility conditions such as haze and rain, the lighting is adjusted to warm light with a lower color temperature to improve visibility and safety; in clear weather, it is adjusted to cold light with a higher color temperature to save energy and maintain good lighting effects.

[0010] On the one hand, the system adjusts the light intensity and color temperature of the tunnel entrance according to the environmental data information of the tunnel entrance, so that the driver can clearly see the situation at the tunnel entrance when passing through the tunnel entrance, avoiding safety accidents.

[0011] On the other hand, the system adjusts the lighting direction, light intensity and color temperature of several lights on the warning column according to the environmental data information in the tunnel and the data information of the vehicle, so that when the driver enters the tunnel, there will be no large brightness difference and "black hole effect" problem. Specifically, the lighting component includes a rotating rod, and several lights are arranged on the rotating rod, and the rotating rod can drive the several lights to rotate circumferentially; the warning column is provided with a vehicle data collection component, and the vehicle data collection component is used to obtain vehicle data at the tunnel entrance; the lighting direction of the lights is adjusted according to the vehicle data, and the rotating rod drives the lights to rotate circumferentially, so that several lights rotate toward the tunnel, and several lights shine toward the tunnel, so as to avoid the problem of large brightness difference when the driver enters the tunnel.

[0012] At the same time, a second environmental data acquisition component is provided in the tunnel, which is used to detect environmental data information in the tunnel; during the circumferential rotation of the lighting lamp, the lighting lamp adjusts the lighting brightness and color temperature of several lighting lamps toward the tunnel according to the environmental data information in the tunnel.

[0013] Therefore, this system is used to adjust the lighting brightness and color temperature at the tunnel entrance and the tunnel section, further improving safe driving and avoiding accidents.

[0014] Furthermore, a wind component is provided on the warning column. When the visibility information of the tunnel entrance is poor visibility or medium visibility, the wind component blows toward the tunnel entrance. The wind component blows toward the tunnel entrance to disperse the particles at the tunnel entrance, avoiding excessive accumulation of particles at the tunnel entrance and affecting the driver's vision. Moreover, blowing at the tunnel entrance can also facilitate air circulation in the tunnel and improve comfort.

[0015] In addition, a connecting plate is provided at the lower end of the lighting lamp, and a telescopic mechanism is provided on the connecting plate, and the telescopic mechanism is used to adjust the height of the lighting lamp on the warning column. The vehicle data acquisition component is used to obtain the height of the vehicle at the tunnel entrance, and adjust the height of the lighting lamp on the warning column according to the height of the vehicle at the tunnel entrance.

[0016] Preferably, a solar panel is arranged on the warning column, and a wind power generation panel is arranged below the warning column. The solar panel and the wind power generation panel provide power for the system.

[0017] A display screen is provided on the warning column; the display screen displays warning information, which is helpful to reduce the probability of traffic accidents.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The present invention provides a highway tunnel entrance early warning system and method. The present invention uses environmental data information and vehicle data to realize a precise prevention and control and early warning system for the highway tunnel entrance, effectively solving the problem that the existing prevention and control early warning device probe is affected by tunnel environmental pollution, resulting in inaccurate monitoring data outside and inside the tunnel, and the inability to achieve precise prevention and control and early warning technology problems;

[0020] When environmental data information and vehicle data at the tunnel entrance and inside the tunnel are collected, the system will adjust the illumination direction, lighting brightness and color temperature of the lights at the tunnel entrance and towards the tunnel, improve the brightness at the tunnel entrance and inside the tunnel and the clarity of reference objects, and effectively solve the "black hole effect" that is easily produced when the human eye is sensitive to sudden changes in light intensity due to the large difference in brightness and color temperature inside and outside the tunnel when the driver enters the tunnel.

[0021] The system effectively solves the problem that when a driver enters the tunnel entrance from outside the tunnel, he is unable to see the vehicles and obstacles (also called foreign objects) in the tunnel due to dark adaptation. If there are foreign objects on the road, the driver cannot respond quickly to emergencies and is prone to collision accidents with foreign objects. The present invention can improve the visibility of the tunnel entrance before the driver enters the tunnel, making it easier for the driver to see the warning information displayed on the display screen and then adjust the driving situation, which is beneficial to reducing the probability of traffic accidents.

[0022] The system is powered by solar energy and wind energy, which is green, environmentally friendly and long-term reliable. BRIEF DESCRIPTION OF THE DRAWINGS

The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example 1

[0033] like Figure 1 As shown, the system includes a warning column 1 arranged at the tunnel entrance, and the warning column 1 is provided with a first environmental data acquisition component 8, a lighting component 3 and a data processing component; the lighting component 3 includes three lighting lamps 6.

[0034] Among them, the first environmental data acquisition component 8 is used to detect the environmental data information of the tunnel entrance, and the environmental data information includes PM2.5 data information; the first environmental data acquisition component 8 includes a PM2.5 detection sensor, which is also called a dust sensor or a particle sensor, and is mainly used to detect the PM2.5 concentration in the air. The working principle of this sensor is usually based on the scattering principle of light, in which a light-emitting element such as an infrared LED or a laser LED emits light, and when particles in the air pass through the light, scattering occurs. The photosensitive element captures these scattered lights and converts them into electrical signals. After amplification and processing, the concentration of the particles is calculated and output by the MCU microcontroller.

[0035] The data processing component is used to obtain visibility information of the tunnel entrance according to environmental data information; specifically, the data processing component obtains visibility information according to the concentration of particulate matter obtained by the PM2.5 detection sensor.

[0036] When the PM2.5 data information is greater than or equal to a first preset value, the data processing component obtains the visibility information of the tunnel entrance as poor visibility; when the PM2.5 data information is less than the first preset value and greater than or equal to a second preset value, the data processing component obtains the visibility information of the tunnel entrance as medium visibility; when the PM2.5 data information is less than the second preset value, the data processing component obtains the visibility information of the tunnel entrance as good visibility; wherein, the first preset value is 150 micrograms / cubic meter, and the second preset value is 75 micrograms / cubic meter.

[0037] The lighting component 3 is used to adjust the lighting brightness and color temperature of several lighting lamps 6 at the tunnel entrance according to the visibility information of the tunnel entrance; when the visibility information is poor visibility, the lighting brightness of several lighting lamps 6 at the tunnel entrance is 3000-5000 lux, and the color temperature is warm light; when the visibility information is medium visibility, the lighting brightness of several lighting lamps 6 at the tunnel entrance is 2000-3000 lux, and the color temperature is warm light; when the visibility information is good visibility, the lighting brightness of several lighting lamps 6 at the tunnel entrance is 500-2000 lux, and the color temperature is cold light.

[0038] When the vehicle does not pass through the tunnel entrance, the lighting direction of the lighting assembly 3 is toward the tunnel entrance, illuminating the tunnel entrance for the driver, so that the driver can clearly see the situation at the tunnel entrance and drive safely.

[0039] In some embodiments, the rotating rod 4 or a plurality of rotating blocks are driven to rotate by a motor.

[0040] Example 2

When the vehicle passes through the tunnel entrance, the rotating rod 4 drives the plurality of lighting lamps 6 to rotate circumferentially, so that the plurality of lighting lamps 6 face the tunnel. At the same time, the rotation speed of the rotating rod 4 is adjusted according to the vehicle speed information, so that the lighting lamps 6 face the tunnel and are always located in front of the vehicle, providing better lighting for the vehicle and avoiding the "black hole effect" caused by a sudden change in light intensity.

[0046] At the same time, several lighting lamps 6 adjust the lighting brightness and color temperature of several lighting lamps 6 toward the tunnel according to the environmental data information in the tunnel. When the visibility information is poor visibility, the lighting brightness of several lighting lamps 6 toward the tunnel is 3000-5000 lux, and the color temperature is warm light; when the visibility information is medium visibility, the lighting brightness of several lighting lamps 6 toward the tunnel is 2000-3000 lux, and the color temperature is warm light; when the visibility information is good visibility, the lighting brightness of several lighting lamps 6 toward the tunnel is 500-2000 lux, and the color temperature is cold light.

When the first vehicle has not reached the tunnel entrance, the lighting direction of the first lighting lamp, the second lighting lamp and the third lighting lamp is toward the tunnel entrance, illuminating the tunnel entrance for the driver; when the first vehicle reaches the tunnel entrance, the first lighting lamp rotates toward the tunnel entrance to illuminate, and continues to rotate back to the direction of illuminating the tunnel entrance; when the second vehicle reaches the tunnel entrance, the second lighting lamp rotates toward the tunnel entrance to illuminate, and continues to rotate back to the direction of illuminating the tunnel entrance; before the third lighting lamp rotates toward the tunnel entrance to illuminate, the first lighting lamp returns to the direction of illuminating the tunnel entrance, and so on, continuously acting on the vehicle.

[0049] In some embodiments, a connecting plate 5 is provided at the lower end of the illuminating lamp 6, and a telescopic mechanism is provided on the connecting plate 5, and the telescopic mechanism is used to adjust the height of the illuminating lamp 6 on the warning column 1.

The first telescopic rod 14, the second telescopic rod 13, and the third telescopic rod 12 adjust the height of the illuminating lamp 6 on the warning column 1 by telescoping.

[0050] The vehicle data includes vehicle height information. When the first vehicle arrives at the tunnel entrance, the length of the first telescopic rod 14 is adjusted according to the vehicle height information.
