Description
Technical field
The utility model relates to traffic safety field, is specifically related to a kind of visual perception intelligent speed-control device based on edge rate principle.
Background technology
In recent years, along with country strengthens the input to infrastructure, mountainous area highway has obtained great development, and the Exploration on Train Operation Safety of highway is also subject to everybody attention always.It is reported, driving over the speed limit is one of traffic violation that causing death's quantity is maximum, and the death tolls that hypervelocity causes accounts for 18.9% of the total death toll of highway.
At present take many kinds of measures to control the speed of a motor vehicle of highway Dangerous Area both at home and abroad, mainly contain stereopsis illusion graticule, speed reduction marking etc. is mated formation, vibrated to thin layer.
On the one hand, there is defect separately in said method, and effect is not good.Stereopsis illusion graticule can cause driver's vigilance, yet for being unfamiliar with the driver of road conditions, thereby easily cause emergency brake, brings out traffic hazard; Thin layer is mated formation due to a little less than vibration sense, therefore very limited on the impact of cart; Vibrating graticule is controlled very effective to dolly speed, but due to the existence of cart, vibrating graticule serious wear, control effect reduces with the growth of tenure of use.
On the other hand, mandatory due to speed reduction marking, this causes some vehicle travelling with safe speed, when running into speed reduction marking, be also forced to slow down, for the driver who is unfamiliar with road conditions, easily cause nervous mood and may produce and drive mistake or brake hard, finally cause security incident.
Exist at present a kind of visual perception based on edge rate to slow down theoretical.Edge rate is in the unit interval, to pass the number of driver's seat edge or interruption, if the spacing of texel is known, edge rate just can be told observer's speed.If road speed remains unchanged, when edge rate increases, driver will perceive speed and uprise, and driver can be slowed down to estimating of velocity level according to self, to reach a travel speed that self-perception is safer.The concrete formula that edge rate (edge rate, ER) solves is:
In formula, ER---edge rate, Hz;
V
g---vehicle actual motion speed, m/s;
T
x---texel spacing, m.
There are some researches show, when edge rate is 12Hz, driver is the most responsive to the perception of speed.
Background based on above, studying a kind of can be very important according to the big or small device that carries out visual perception intelligent speed-control of vehicle speed.
Utility model content
The purpose of this utility model is to provide a kind of visual perception intelligent speed-control device based on edge rate principle, it is arranged on roadside barrier along turnpike driving road direction, utilize knotmeter to gather the size of the speed of a motor vehicle, and the theoretical safe speed in the actual measurement speed of a motor vehicle and this section is contrasted, thereby the spacing that control is arranged at the edge column on roadside barrier selectively realizes intelligent speed-control.
For achieving the above object, the utility model is included in the radar meter that trackside arranges, radar meter connects the input end of the single-chip microcomputer in its downstream, the output terminal of single-chip microcomputer connects variable information advices plate, the motor driver drive motor in Single-chip Controlling variable information advices plate downstream, on the roadside barrier in motor downstream, be provided with slide rail, the some edge columns that are placed in slide rail of Electric Machine Control.
Described radar meter is arranged on the trackside at 2000 meters of, Dangerous Area upstream.
Described radar meter adopts fixedly velocity radar S3 of Si Deke.
Described variable information advices plate is arranged on the trackside at 1500 meters of, Dangerous Area upstream.
Described single-chip microcomputer is arranged on the behind of variable information advices plate.
Described single-chip microcomputer adopts MSP430 single-chip microcomputer.
Described start edge column and terminating edge column are placed in respectively the slide rail at, 1000 meters of Dangerous Area upstreams and 700 meters of.
Described edge column is 60.
Compared with prior art, the utility model finds to exceed the vehicle of theoretical safe speed by radar meter, thereby by the distance changing between edge column, improve edge rate again, make driver perceive own speed higher, produce tension and take in time deceleration behavior, to exceeding the vehicle of theoretical safe speed, do not change the distance between edge column, like this by adopting the comparing result of actual measurement speed and theoretical safe speed, selectively vehicle is taked to control fast measure, strengthened the intelligent of control speed.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further explained to explanation.
Referring to Fig. 1, 2 and 3, the employing Si Deke that the utility model comprises the trackside that is arranged on 2000 meters of, Dangerous Area upstream is the radar meter 3 of velocity radar S3 fixedly, radar meter 3 connects the input end of the MSP430 single-chip microcomputer 5 in its downstream, the output terminal of single-chip microcomputer 5 connects the variable information advices plate 4 that is arranged on the 1500 meters of tracksides in Dangerous Area upstream, single-chip microcomputer 5 is arranged on the behind of variable information advices plate 4, single-chip microcomputer 5 is controlled motor driver 8 drive motor 9 in variable information advices plate 4 downstreams, on the roadside barrier in motor 9 downstreams, be provided with slide rail 6, motor 9 is controlled 60 and is equidistantly arranged in the edge column 7 in slide rail 6 by 5m, start edge column and terminating edge column are placed in respectively the slide rail 6 at, 1000 meters of Dangerous Area upstreams and 700 meters of.
For a kind of visual perception intelligent speed-control device based on edge rate principle of the utility model is further understood, now its principle of work is described further.
Referring to Fig. 3, motor vehicle 1, along in the runway direction running of highway 2, when radar meter 3 is measured after the speed of a motor vehicle, inputs to measured data in single-chip microcomputer 5, and single-chip microcomputer 5 is relatively surveyed the size of the speed of a motor vehicle and this section safe speed.If the actual measurement speed of a motor vehicle is below theoretical safe speed, variable information advices plate 4 shows green safety traffic information; If the actual measurement speed of a motor vehicle is higher than theoretical safe speed, variable information advices plate 4 shows red information warning, and drive edge column 7 to move by motor driver 8 drive motor 9, reach the effect of automatic shortening edge column 7 spacing, thereby it is higher by raising edge rate, to make driver perceive own speed, produces tension and takes in time deceleration behavior.According to device, total length and known safe speed are installed, we are easy to get the shortest time of travelling in this section, therefore programme by single-chip microcomputer 5, utilize motor driver 8 drive motor 9, make edge column automatically shorten its spacing until every 3.5 meters one, after 2 minutes, edge column spacing starts to return to every 5 meters one of initial value.
