Description

Guide type highway anti-fogging system

Technical field

The present invention relates to a kind of highway anti-fogging system, particularly a kind ofly adopt real-time detection, give warning in advance and the guide type highway anti-fogging system of on-the-spot guiding, mainly be applicable to highway and in the low visibility environment such as greasy weather, motor vehicles carried out safe guidance.

Background technology

Mist is to be suspended in a large amount of trickle water droplet in the Air Close To The Earth Surface or the visual aggregate of ice crystal.According to world Meteorology Organization, make visibility be reduced to the mist that is called below 1 kilometer, the size of mist can see that according to level degree represents.So-called horizontal visibility refers to that twenty-twenty people under weather condition at that time, can see and recognize the maximum horizontal range of the object of black and size appropriateness daytime from sky background; Then be the maximum horizontal range that can see or determine certain brightness light night.

The motor vehicle driving personnel are known road ahead information by light to the reflection of environment object, motor vehicle driving personnel's eyes can obtain enough Safety Pre apparent distances under the condition of visibility good, take in advance various counter-measures by the Safety Pre apparent distance of abundance.Visibility reduces when mist occurring, because motor vehicle driving personnel's the Safety Pre apparent distance has been shortened, in the constant situation of speed, the time that human pilot can be taken measures when running into emergency case just has been reduced.Mist mainly concentrates on visible light wave range to the impact of road traffic, and the vehicle drive personnel also mainly concentrate on visible light wave range to the perception of object on every side, and the greasy weather Accident prevention measure of having implemented at present is that envelope road or speed limit are travelled.

Know from crash analysis, the road traffic accident that occurs because of the greasy weather at highway mainly be since not the burst visibility of early warning reduce institute and cause, and the main cause that causes burst visibility to reduce is a mist.Usually group's mist that horizontal diameter is very little is little to the harm of road traffic, and group's mist medium or larger horizontal diameter is large especially to the harm of traffic.The mist of the relative other types of group's mist, its flowability is larger, relative diameter is larger, the local highway section visibility that can make highway in the short time at the utmost point is from normally dropping to below the thick fog, thereby just makes in this highway section or the vehicle in this highway section of approach has little time to adopt an effective measure and therefore have an accident.The physical features of such mist is that horizontal diameter concentration large, mist is higher, and rapidly mobile, is difficult to use the prior art means to find and early warning.For example, the control device that Chinese patent CN1233810 " sensing and controlling device for fog weather " is disclosed to be identified greasy weather weather and send control signal is installed and used at road, detect by humidity sensor, output terminal output greasy weather automatic control electric signal through the humidity amplification controller, the guiding lamp of control wired connection is finished guiding, reduces the generation of fogday traffic accident.This device is as the control foundation by humidity sensor Test Field humidity, in fact humidity and mist do not have absolute corresponding relation, and wired alarm signal is more single, is difficult in time find cause group's mist that burst visibility reduces with effective early warning, has a strong impact on anti-fog effect.

For vehicle in transit, at first to know when will enter the fog-zone; Next is when travelling in the fog-zone, needs again have a kind of device to indicate clearly trend of road and the position of the band that stops in emergency.Although the protuberant guide post of delineator or the active illuminating of active illuminant is arranged at present, it not synchronous flashing.In the low-visibility road traffic application, the active illuminant guiding device that the greasy weather glimmers at random can make the driver to the failure of road previewing, and then loses the effective judgement to road profile, so use the guiding device effect of at random flicker to against one's expectation.

The single information integrated manipulator C of guide type highway anti-fogging system only is responsible for data acquisition and comparison and the distribution in a control highway section, and being provided with a plurality of information integrated manipulator C such as system then each other can networking and consist of dcs.Dcs has the ability to the aggregation of data operation of each information node, under the dcs management, can carry out COMPREHENSIVE CALCULATING to the visibility numerical value of each information node of system-wide section and obtain the real-time numerical value of visibility of each node of system-wide section, realize that Exact Forecast is carried out in live telecast to road visibility.Simultaneously, can also use the powerful arithmetic capability of distributed information integration controller to access other measuring and controlling equipments, such as anemoscope, thermometer etc., and the real-time detector data that provides the said equipment sensor to obtain.

The embodiment guide type highway anti-fogging system is on-the-spot to be installed referring to Fig. 2, and antifog early warning display screen Y is installed in visibility detection instrument V the place ahead, and S is the distance of early warning information reach; The synchronous delineator O of sun power and the synchronous protuberant guide post L of sun power installation site are at visibility detection instrument V rear, and the synchronous delineator O of sun power is installed on the interior side rail H of road and the outer side rail E of road; The synchronous protuberant guide post L of sun power is installed in the inboard sideline D of road and road outside sideline J; The synchronous protuberant guide post L of sun power installing space is consistent with the synchronous delineator O of sun power, but both arranged in dislocation, but also equipotential is installed; The synchronous delineator O of present embodiment sun power and the synchronous protuberant guide post L of sun power arranged in dislocation.R is that road, F are direction of traffic among Fig. 2.

This guide type highway anti-fogging system principle of work is as follows:

With the spacing of minimum safe testing requirement road traffic visibility detection instrument V is set along the line at road, minimum safe detection spacing is the physical features according to this zone greasy weather, such as the data such as diameter of common mist, and according to the nearest safe spacing of these data configurations; Such as 3000 meters of the common group's mist diameters that harm arranged in this zone, following its inner concentration of group's mist of this diameter does not constitute a threat to, and minimum safe spacing that then should the zone is exactly 3000 meters.Visibility detection instrument V can effectively find for example to roll into a ball the sudden visibility real-time change that mist causes, and the visibility numerical value that road is real-time sends to information integrated manipulator C; Information integrated manipulator C compares to real-time visibility numerical value, and when finding low visibility in defined threshold, information integrated manipulator C uses the display mode transmission demonstration information with antifog early warning display screen Y coupling, starts immediately antifog early warning display screen Y; When if upper equipment is arranged, also can upload real-time visibility data for upper equipment by communication interface; If the equipotential same category of device is arranged, then share the separately real time data of section by communication interface and the networking of equipotential same category of device.Because antifog early warning display screen Y mounting points position is in the place ahead of visibility detection instrument V, thus when any point of system-wide section is found low visibility in threshold value, all can before entering the low visibility zone, vehicle give effective early warning, thus the generation of minimizing accident.When needs provide when guiding, information integrated manipulator C to send the instruction that starts the synchronous delineator O of sun power to the fog-zone, the synchronous delineator O of sun power is activated, and is attached to active illuminating reflex reflection diascope on the delineator and also is activated and begins synchronous flashing.The synchronous delineator O of sun power mainly provides the demonstration of road boundary profile to reach backward to vehicle in transit, and car provides reverse perspective, when having vehicle to pass through active illuminating reflex reflection diascope, can stay projection to rear car, can find in advance existing and the position of front truck with car after an action of the bowels.During the low visibility state, vehicle in transit can be found highway sideline and stop in emergency the band position by day; Under night low visibility state, especially in case of emergency, vehicle in transit be difficult to find the to stop in emergency accurate location of band needs to use the synchronous protuberant guide post L of sun power.The synchronous protuberant guide post L of sun power is installed in sideline, the road outside, the synchronous protuberant guide post L of sun power uses the flicker frequency synchronous flashing consistent with the synchronous delineator O of sun power, after the startup, can effectively indicate the band that stops in emergency between guardrail and the highway sideline, for vehicle in transit provides the good expected Safety Pre apparent distance, in emergency circumstances vehicle in transit can enter accurately rapidly to stop in emergency to be with according to sign and dodging.

With regard to the enforcement means, the present invention surveys the real-time numerical value of visibility at visible light wave range, use the means of communication with the live reach of the visibility numerical value in next highway section, its leading can determine according to factors such as the setting speed of a motor vehicle in road conditions, this highway section, surrounding environment.The live reach of visibility numerical value makes guide type highway anti-fogging system have larger application adaptability.Expected trend of road, pre-visual informations of actual time safety such as front vehicle position, the band position of stopping in emergency, road outline boundary position, road inner side edge line position and the inboard boundary position of road closely are provided for vehicle in transit at the guiding synchronous delineator O of synchronous flashing sun power of highway section system-wide setting and the synchronous protuberant guide post L of sun power.Here " expection " refer to the device synchronous flashing for guiding, a kind of visual effect of expected " line " that repeats to realize is provided, should " line " overlap with real road, this make vehicle in transit to the road ahead state realization can expect understanding; If guiding device is to glimmer at random then effect can be opposite and becomes and can not expect.The low visibility state, especially night during low visibility in emergency circumstances, effectively indicate the band that stops in emergency between guardrail and the highway sideline, vehicle in transit can be entered rapidly accurately stop in emergency band to be dodged, can greatly improve travelling in fog day safety.

Safe previewing is from the technical standpoint analysis, and the motor vehicle driving personnel need enough Safety Pre apparent distances can the safe driving motor vehicle, and its safe driving is relevant with the Safety Pre apparent distance.Minimum safe is driven requirement should satisfy M 〉=T+H, and in the formula, vehicle passes through in the M=Safety Pre apparent distance, T=reaction time distance, H=brake needed distance.The motor vehicle driving personnel need to have enough Safety Pre apparent distances can satisfy have time enough and the distance take measures to ensure safety, after visibility reduces, the Safety Pre apparent distance can shorten, need to pass through technological means this moment, take to give warning in advance such as the present invention and show and to prolong the Safety Pre apparent distance, thereby ensure minimum safe previewing requirement, only in this way can avoid the generation of accident.

Referring to Fig. 3, embodiment guide type highway anti-fogging system workflow is: after visibility detection instrument V obtains the real-time numerical value of visibility, with communication to information integrated manipulator C; Information integrated manipulator C compares to the real-time visibility numerical value that obtains, and sends to simultaneously epigyny device; When comparison does not meet the antifog early warning display screen Y of startup, restart receiving real-time data and comparison; If satisfying, numerical value starts threshold value, then by the wireless digital transmission device information is advanced to the upper demonstration of antifog early warning display screen Y, in advance the place ahead is entered the accurate information notification vehicle in transit of fog-zone, start simultaneously the synchronous protuberant guide post L of the synchronous delineator O of sun power and sun power, carry out guiding in real time for the vehicle that enters the fog-zone; When visibility numerical value can not satisfy the startup threshold value, and the duration greater than shut-in time during threshold value, send again the instruction of closing antifog early warning display screen Y and the synchronous delineator O of sun power, the synchronous protuberant guide post L of sun power, so circular flow.

In road traffic is used, be lower than the secure threshold that visibility below 1000 meters just can trigger highway, so it is very high that highway does not need usually with the detection sensitivity of visibility detection instrument V, can satisfy the visibility below 2500 meters surveyed and just can satisfy actual operation requirements.The special-purpose visibility detection instrument of the road traffic that present embodiment uses Hangzhou great achievement public safety Engineering Co., Ltd of BDCom to produce, the detection sensitivity of this visibility detection instrument is 10~3000 meters, can satisfy the early warning needs in road traffic greasy weather fully.

The information integrated manipulator that information integrated manipulator C uses Hangzhou great achievement public safety Engineering Co., Ltd of BDCom to produce, the supporting 2.4G radio receiving transmitting module of the information that aims at integrated manipulator C that the local digital wireless receiving and dispatching uses Hangzhou Command Communication Equipment Co., Ltd to provide, this module has the bidirectional data transfers ability.

Selectable antifog early warning display screen Y has three classes, and a class is to show that with pure figure information is simple and clear, is adapted at the environment that road conditions are simple or the speed of a motor vehicle is higher and uses; Equations of The Second Kind is figure and literal mixed type, is adapted at the road conditions complexity, and the environment that the speed of a motor vehicle is lower uses, and is characterized in also can adding simple literal early warning information outside fixing caution figure, makes early warning more accurate; The 3rd class is the dot matrix display mode, can realize the free conversion of figure and literal, is characterized in being fit to the application of various different roads, especially is fit to complex road condition and the higher road occupation of the speed of a motor vehicle.The antifog early warning display screen of YDC type that embodiment uses great achievement public safety Engineering Co., Ltd of Hangzhou BDCom to produce, belong to the mixed type display screen, it uses 32 * 64 dot matrix to show character, figure uses the triangle warning mark that meets Chinese national standard, the LED that is not less than 35 degree with half strong angle forms the figure type matrix, and LED arranges along the triangular warning sign, can strengthen to show the triangular warning figure, display screen uses 600 * 800 millimeters housing visual, about 150~250 meters of decipherment distance.

Application example:
