Guide type highway anti-fogging system

Abstract

The invention discloses a guide type highway anti-fogging system, which comprises a visibility detector, an anti-fogging early warning display screen and an information integration controller, wherein the visibility detector is arranged in a distance meeting lowest safety testing requirements on the way of the highway, and the anti-fogging early warning display screen is arranged in front of the visibility detector according to the running direction of a vehicle; the visibility detector sends real-time visibility data of the road to the information integration controller when detecting suddenreal-time visibility change, the real-time visibility data is compared with built-in data in a database and a control threshold value, and the anti-fogging early warning display screen is started immediately when the visibility is lower than the stipulated threshold value. The anti-fogging system is scientific, rational and practical, takes the real-time visibility data as a basis for starting the early warning display and guide devices on foggy days, can discover and early warn mass of fog and the like which cause sudden visibility reduction in time, effectively reduces the incidence rate oftraffic accidents when the visibility is low on foggy days, and ensures road traffic safety.

Description

technical field [0001] The invention relates to a highway anti-fog system, in particular to a guided highway anti-fog system which adopts real-time detection, early warning and on-site guidance, and is mainly suitable for monitoring motor vehicles in low-visibility environments such as foggy days on highways. Safe boot. Background technique [0002] Fog is a visible collection of large numbers of fine water droplets or ice crystals suspended in the atmosphere near the surface. According to the regulations of the World Meteorological Organization, the fog that reduces the visibility to less than 1 km is called fog, and the size of the fog is expressed according to the horizontal visibility. The so-called horizontal visibility refers to the maximum horizontal distance that a person with normal vision can see and recognize a black and moderately sized target object from the sky background in the daytime under the weather conditions at that time; at night, it can see or determi...

Problems solved by technology

At present, although there are active luminous outline markers or active luminous raised road signs, they do not flash synchronously

In the field of low-visibility road traffic applications, the randomly flashing active light-emitting guiding device in foggy days will make the driver fail to foresee the road, and then lose the effective judgment of the road outline, so the effect of using a randomly flashing guiding device will be contrary to expectations
