Description
Technical field
The utility model relates to highway communication fields, more specifically, it relates to a kind of freeway tunnel black-hole effect
Inhibition system.
Background technique
When automobile approaching is compared with long tunnel hole, sky, outdoor road surface, nearby buildings in the driver visual field etc. it is bright
Degree is high far beyond the brightness of tunnel portal.Under the action of induction, although actually also there is comparable brightness at hole, drive
It sails people and still feels that hole is very black, as a " black hole ", so that being beyond recognition the situation near hole, barrier is also difficult to send out
Existing, this phenomenon is known as " black hole " effect.
" black-hole effect " is the problem of vcehicular tunnel almost not can avoid, and reason is that tunnel is a tubular articles, is expert at
Effective visual light can not be formed on vehicle direction, from the appearance long tunnel is exactly a black hole, especially linear type tunnel
It is just more prominent, it thereby results in driver and is entering tunnel in a flash, have the complete dark stress reaction of vision, reason is Tunnel
Inside and outside luminous intensity difference is huge, and human eye needs an adaptation process.Thus " black-hole effect " is the more normal of tunnel driving accident
The inducement seen, and the severity that accident occurs is larger, need to be solved by relevant art means.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of freeway tunnel black hole effects
It should inhibit system, can effectively inhibit black-hole effect, improve the safety of driving.
To achieve the above object, the utility model provides following technical solution：
A kind of freeway tunnel black-hole effect inhibition system, including the unrestrained reflective areas being arranged on the entrance ground in tunnel
With the unrestrained reflector on the entrance roof for being fixed on tunnel, the unrestrained reflector is opposite with the reflective surface of unrestrained reflective areas, described unrestrained
Reflective areas covers the ground inside and outside tunnel, and the unrestrained reflector and the projection of unrestrained reflective areas in the vertical direction have intersection,
The system further includes being arranged in road vehicle detector, traffic lights and controller, and the wagon detector passes through
Digital video decoder connects controller, and the traffic lights connect and are controlled by the controller.
Preferably：It further include the alarm being arranged in by road, the alarm connects and is controlled by the control
Device processed.
Preferably：The alarm is combined aural and visual alarm.
Preferably：The unrestrained reflector includes substrate, the diffusing reflection layer coated in substrate surface and is covered on
The protective layer of the light transmission of diffusing reflection layer surface.
Preferably：The unrestrained reflective areas is the one layer of diffusing reflection coating brushed on the ground.
Preferably：The wagon detector and traffic lights are the tops for being installed in the inlet in tunnel.
Preferably：The controller is dsp controller.
Compared with prior art, the utility model has the advantages that：On daytime, ambient lighting is mapped to unrestrained on ground the system
Reflective areas generates diffusing reflection, and reflected light line a part is injected on the wall in tunnel, and a part is mapped on unrestrained reflector and goes forward side by side
Second of diffusing reflection of row overflows transmitting effect so that one section of region of the entrance in tunnel is illuminated, to make tunnel portal
The difference of brightness and ambient brightness is smaller, and when automobile enters the moment in tunnel, the eyes of driver will not generate too big light and shade alternating,
So as to which black-hole effect is effectively relieved, the safety of driving is improved；In addition, driver drive motor is travelled to the entrance in tunnel
When, wagon detector acquires the information of vehicle flowrate in front of the entrance in tunnel, is then obtained on road by digital video decoder
The data of vehicle, data are transferred to controller, and when vehicle flowrate is excessive or speed is slower, it is bright that controller controls traffic lights
It rises, reminds driver to slow down and pay attention to front vehicles, be in people's adaptation of eye tunnel so as to make vehicle enter tunnel with slower speed
Brightness win more times, further increase the safety of driving.

Specific embodiment
Referring to Figures 1 and 2, a kind of freeway tunnel black-hole effect inhibits system, the entrance including tunnel 1 is arranged in
Unrestrained reflective areas 2 on face and the unrestrained reflector 3 being fixed on the entrance roof in tunnel 1 overflow the anti-of reflector 3 and unrestrained reflective areas 2
Smooth surface is opposite, overflows a certain range of ground inside and outside the covering tunnel 1 of reflective areas 2, overflows reflector 3 with unrestrained reflective areas 2 in vertical side
Upward projection has intersection, which further includes setting in road vehicle detector 4, traffic lights 5 and control
Device processed, wagon detector 4 connect controller by digital video decoder, and traffic lights 5 connect and are controlled by controller.
The working principle of the system is：On daytime, ambient lighting is mapped to the unrestrained reflective areas 2 on ground, generates diffusing reflection, quilt
Light a part of reflection is injected on the wall in tunnel 1, and a part is mapped on unrestrained reflector 3 and carries out second of diffusing reflection, is overflow
Transmitting effect is so that one section of region of the entrance in tunnel 1 is illuminated, to make brightness and the ambient brightness of 1 entrance of tunnel
Difference is smaller, and when automobile 6 enters the moment in tunnel 1, the eyes of driver will not generate too big light and shade alternating, so as to be effectively relieved
Black-hole effect improves the safety of driving.
In addition, wagon detector 4 acquires the entrance in tunnel 1 when in front of the traveling to the entrance in tunnel 1 of driver drive motor 6
Then the information of vehicle flowrate in front obtains the data of vehicle on road by digital video decoder, data are transferred to controller,
When vehicle flowrate is excessive or speed is slower, controller control traffic lights 5 are lighted, and are reminded driver to slow down and are paid attention to front vehicle
, so as to make vehicle enter tunnel 1 with slower speed, more times are won for the brightness in people's adaptation of eye tunnel 1, into
One step improves the safety driven.
In the present embodiment, wagon detector 4 and traffic lights 5 are the tops for being installed in the inlet in tunnel 1.
Here controller is dsp controller.
The system further includes the alarm being arranged in by road, and alarm connects and is controlled by controller.When 1 entrance of tunnel
When the vehicle flowrate at place is excessive, controller controls alarm and issues alarm signal, to remind vehicular traffic, so as to preferably lift
The attention of driver.Alarm is combined aural and visual alarm.
The system further includes host computer, and controller and host computer communicate to connect.Controller uploads the traffic conditions at scene
To host computer, the long-range monitoring of traffic may be implemented, brought convenience for traffic scheduling.
Referring to Fig. 3, in the present embodiment, overflowing reflector 3 includes substrate 301, the diffusing reflection layer coated in 301 surface of substrate
302 and be covered on 302 surface of diffusing reflection layer light transmission protective layer 303.And the unrestrained reflective areas 2 on ground is then one layer of brush
Diffusing reflection coating.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
