Abstract
The invention relates to a real-time highway monitoring system under the severe weather condition. Weather change, especially severe weather causes great risk of driving on the highway, influences transportation, and results in great loss of national properties as well as human life and properties. The system is composed of a weather information detector module (1), the weather information detector module is connected with a data collector (2), the data collector is connected with a front-end processor (3), and the front-end processor is connected with a manual controller (4), a communication interface device (5) and a PC (6). The system is used for monitoring the weather of the highway in real time.
Description
technical field:
the present invention relates to the highway real-time monitoring system under a kind of bad weather condition.
background technology:
in recent years, the development of China's expressway construction is very fast, and since building up China's Article 1 highway from 1988, to the end of the year 2007, China's highway mileage open to traffic, close to 4.5 ten thousand kilometers, will continue to keep second place of the world, is only second to the U.S..According to " national expressway network planning ", the freeway net that China will build with 30 years " seven penetrate nine vertical 18 horizontal strokes ", total kilometrage will reach 8.5 ten thousand kilometers, form " capital connection provincial capital, provincial capital communicates with each other, connect main districts and cities, cover important counties and cities " highway network, be communicated with all important cities, transport hub, the whole nation, comprise railway terminal 67, 50, water route hinge and highway terminal more than 140, by covering more than 10 hundred million population, the development that the GDP in direct service area territory accounts for more than 85% highway of national total amount creates more and more important impact to national economy.
but the change of weather condition, particularly exceedingly odious weather condition, travel to the vehicle of highway and bring huge risk, not only have a strong impact on communications and transportation, but also cause the heavy losses of national wealth and people's lives and properties.So road weather condition monitoring be highway science operation an important evidence, rain, snow, mist, accumulated snow, freeze etc. the operation of situation on highway have direct impact.The impact of meteorological condition on traffic shows a lot of aspect.Be mainly manifested in the physical property, the observation aspect such as sight line, vehicle inherently safe that change road surface.Major casualty and impact have:
a, mist: mist causes traffic hazard mainly through reducing visibility.In the weather phenomenon of the pernicious traffic hazard caused in China's most area, having the greatest impact of mist.The disastrous fogy of the dense fog particularly very low observable of <50 rice is the major reason causing major traffic accidents, often causes several the even continuous rear collision of tens of automobiles.Dense fog usually causes great vehicle to lose and casualties, causes Speed Limitation on Freeway or closedown, incurs loss through delay running time, causes tremendous economic to lose.
b, rainfall: rainfall is also affect the modal meteorological element of expressway traffic safety, and it makes coefficient of road adhesion reduce, cause automobile brake distance to increase, and defective steering stabilizer easily occurs and controls malfunctioning thus jeopardize traffic safety.Rainfall simultaneously makes visibility reduce, and driver's blurred vision is unclear, causes faulty drive.In addition, after rainfall, differ if any ponding or dry wetting in road surface, surface friction coefficient is uneven, and car brakeing is deteriorated, thus causes traffic hazard.In mountain area, heavy rain also usually causes mountain torrents, massif landslide or rubble flow, thus causes vehicle to be rushed, bridge collapse, and road is ruined; In Plain and basin, heavy rain usually causes flood, and cause road to be flooded, traffic is obstructed.C, ice and snow: ice and snow is the same with rainfall, the heavy snow danced in the air all over the sky makes visibility reduce, and once road snow is pressed or melt under sunlight irradiates daytime, the cooling of nightside road surface is frozen, cause the inside surface friction coefficient significantly to reduce, have a strong impact on operation and the braking ability of vehicle, make control malfunctioning, vehicle dallies, skid or break away, thus jeopardizes traffic safety.
d, strong wind: strong wind all has a significant impact for vehicle travel resistance, energy consumption, anti-lateral tilt and resistant slide performance, particularly side direction strong wind are on the traveling impact of high case, two case automobile more so.Strong wind can cause the weather such as sandstorm, sand, blowing snow, floating dust, affects expressway visibility.Strong wind easily makes the obstruction that fractures such as roadside trees, bar line class, easily makes Plastic, hay class, filiform class etc. float to road surface causes vehicle slip, out of control; Easily make dust, sand, dust devil affect sight line and cause traffic hazard.E, frost: when highway pavement has a frost, surface friction coefficient is close to snow face, and the physical property of freezing with snow face of freezing after rain is the same, thus causes traffic hazard.F, high temperature: hot weather is simultaneously by the impact of heat absorption, friction and vehicle exhaust etc., and express highway pavement temperature is more much higher than temperature, sometimes up to more than six or seven ten degrees Celsius, therefore doughnut is heated, tire internal gas pressure is raised, long-distancely to run at high speed, very easily cause " blowing out ".High temperature directly affects the physiology of driver, psychology and the state of mind, without air-conditioned coach more fatiguability, absent minded even in administration.
summary of the invention:
the object of this invention is to provide the highway real-time monitoring system under a kind of bad weather condition.
above-mentioned object is realized by following technical scheme:
