Abstract
The utility model discloses a kind of traffic lights amber lights to pass through time intelligence suggestion device, it is fixed on the front of traffic lights amber light, including prism, rotation axis, stepper motor and controller, the rotation axis is arranged in prism lower part, the stepper motor drives rotation axis rotation, the controller is equipped with display screen, for showing and inputting traffic lights height and road speed limit.The traffic lights amber light of the utility model principle different with yellow light refractive index to feux rouges using prism by time intelligence suggestion device, driver is prompted to pass through the remaining time at crossing by the color of amber light, can be effectively prevented from can not judge traffic accident caused by yellow time.
Description
Technical field
The utility model belongs to traffic lights field, and specifically a kind of traffic lights amber light is prompted by time intelligence
Device.
Background technique
In recent years, China's car ownership shows explosive growth, and from 2013 to 2017 year, car ownership is with height
Speed in 10% increases.While car ownership sharp increase, traffic accident rate can not have always been high any more yet.Have
Statistical data is shown, is rushed traffic accident caused by amber light and is up to 90%.Due to different sections of highway traffic lights timing difference, driver
Often it is difficult that effective judgement can be made by usual friendship mouth to vehicle according to the amber light scintillation time estimated.Although current some letters
Signal lamp is mounted with liquid crystal inverse timing device, but as being difficult to judge under locating speed whether can lead to safely for driver
It crosses, therefore there are many security risks.
Utility model content
In order to solve the above technical problems existing in the prior art, it is yellow to provide a kind of traffic lights for the utility model
Lamp is fixed on the front of traffic lights amber light, including prism, rotation axis, stepper motor by time intelligence suggestion device
And controller, in prism lower part, the stepper motor drives rotation axis rotation for the rotation axis setting, sets on the controller
There is display screen, for showing and inputting traffic lights height and road speed limit.
Further, the controller is fixed on traffic lights by fixed part.
The traffic lights amber light of the utility model is by time intelligence suggestion device using prism to feux rouges and yellow light
The different principle of refractive index is prompted driver to pass through the remaining time at crossing by the color of amber light, can be effectively prevented from nothing
Method judges traffic accident caused by yellow time.
Detailed description of the invention
Fig. 1 is that the traffic lights amber light of the utility model passes through time intelligence suggestion device structural schematic diagram；
Fig. 2 is that the traffic lights amber light of the utility model passes through time intelligence suggestion device lateral plan.
Fig. 3 is controller schematic diagram；
Fig. 4 is controller another side schematic diagram；
Fig. 5 is the principles of the present invention figure.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figs. 1-5, the traffic lights amber light of the utility model is fixed on traffic by time intelligence suggestion device
The front of signal lamp amber light, including prism 1, rotation axis 2, stepper motor 3 and controller 4, rotation axis 2 are arranged in prism 1
Lower part drives rotation axis 2 to rotate by stepper motor 3, and controller 4 is equipped with display screen 5, for showing and inputting traffic lights height
With road speed limit.Controller 4 is fixed on traffic lights by fixed part 6.
The utility model has the principle of different refractivity according to prism to different wave length, and being installed on can basis
β occurs in the rotation axis 2 of axial-rotation amber light remaining time t at a certain angle.To realize by the difference of " yellow -> red "
Color spectrum makes police when signal lamp amber light flashes by crossroad safety come the driver for signal lamp different distance of adjusting the distance
Show.Concrete principle is as follows:
Amber light can be divided into yellow light and feux rouges by prism using orange-colored light in traffic lights.
Known traffic lights height h, feux rouges refractive index n, road speed limit v, prism apex angle ɑ, crossing overall length x, if amber light is surplus
Remaining scintillation time is t, and the angle that prism rotates at any time is β, wherein∠ 1 is the yellow light angle of emergence, and ∠ 2 is prism
The incidence angle of exit facet, ∠ 3 are the angle of emergence of the prism plane of incidence, and ∠ 4 is yellow light incidence angle.
It can be obtained according to the distance relation of traffic lights height and traveling:
It can be obtained according to angular relationship:
It can be obtained according to refraction theorem:
It can be obtained according to angular relationship:
∠ 4=alpha-beta (5)
It can be obtained according to refraction theorem:
Road speed limit v, amber light remaining time t where formula (6) gives signal lamp and prism rotate angle beta three's
Relationship.
