Description

Technical Field

[0001] The utility model belongs to the technical field of traffic safety and sight guidance, and particularly relates to a tunnel continuous intelligent sight guidance device. Background Art

[0002] With the development of modern traffic infrastructure, tunnels play an important role in the highway traffic network. Due to factors such as poor lighting, narrow space, and high driving speed in the tunnel, it is easy for drivers to have problems of not being able to see clearly and far when driving in the tunnel, resulting in an inability to react in time when encountering obstacles. To avoid this phenomenon and improve driving safety, existing sight guidance devices are set in the tunnel to provide visual cues for drivers, improve the visual experience in the tunnel, relieve driver fatigue, and help improve the tunnel traffic capacity and ensure traffic safety. When an accident occurs in the tunnel, early warning needs to be carried out as soon as possible to avoid the expansion of the accident. However, the existing early warnings are all set up temporary warning components manually, resulting in delays and making it difficult to give early warnings in time.

[0003] Publication No. CN211973195U discloses a visual safety guidance component for highway tunnels. A number of reflective rings are provided on the inner wall of the tunnel body, a number of wavy reflective signs are provided on the inner wall of the tunnel body and are located below the reflective rings, and a number of self-luminous guiding signs are installed at the top of the curbstone. By setting a number of reflective rings, when there is no lighting in the tunnel, the reflective rings can automatically reflect light through the reflective film to ensure driving safety. At the same time, the reflective rings use different colors, and the problem of the black hole effect generated by drivers is effectively solved according to the brightness of the colors. By setting a number of wavy reflective signs, direction guidance is provided for drivers. Cooperating with the set number of self-luminous guiding signs, according to the distance between each self-luminous guiding sign, the driver is prompted to maintain a safe distance in the depth of the tunnel during tunnel driving, relieve visual fatigue, and reduce the safety level of tunnel driving. However, when solving the black hole effect problem, it is achieved by using different colors for the reflective rings. When the lighting equipment in the tunnel is normal and the tunnel lights are on, for the vehicles just entering the tunnel, due to the ambient light changing from bright to dark, this technical means is still difficult to eliminate the black hole effect.

[0004] Therefore, the existing sight guidance devices have problems of poor effect in eliminating black hole and white hole effects and lag in early warning of tunnel accidents. Summary of the Utility Model

The power supply component is used for being electrically connected to other components in the device to provide power for other components in the device. Since the tunnel is relatively long, Figure 1 only the tunnel entrance 2 and a part of the inner wall 1 of the tunnel are shown schematically.

[0033] In order to provide guidance for the drivers in the tunnel, the induction component 3 is continuously arranged from the starting point to the ending point of the tunnel.

The length range of the section close to the tunnel entrance 2 ∈ [60 meters, 80 meters]. This length range is determined according to the range of the vehicle driving speed in the tunnel.

[0034] In order to avoid visual fatigue of the drivers, both the high-brightness induction lamp 31 and the low-brightness induction lamp 33 include a constant-on induction lamp, a flashing induction lamp and a flowing-water type dynamic induction lamp. Arrange the setting quantity and setting position of various induction lamps reasonably according to the requirements.

[0035] In order to ensure that when the high-brightness induction lamp 31 and the low-brightness induction lamp 33 fail, the line-of-sight guidance can still be provided for the drivers, the induction component 3 further includes a reflective strip 32.

[0036] In order to obtain the status in the tunnel in time, the monitoring component 4 is continuously arranged from the starting point to the ending point of the tunnel. The above-mentioned monitoring component 4 includes an infrared sensor 41 and a current sensor 42.
