Description
Technical field
The invention belongs to traffic safety technology fields, and in particular to a kind of expressway fog of gamut real-time monitoring is pre-
Alert and inducible system.
Background technique
In recent years, the traffic accidents much caused by mist have absolutely proved that a mist hands over highway
The harm power for leading to safety is big.The expressway traffic accident that group's mist is caused is often extremely serious, to the lives and properties of the masses of the people
Safety brings great threat.Therefore, the group's mist early warning and inducible system of highway are established, is reduced because of group's greasy weather gas pair
The influence of expressway traffic safety, guidance vehicle drive safely in fog-zone domain, to reduce and effectively prevention highway
Traffic accident ensures that the security of the lives and property of broad masses of the people has a very important significance.
Currently, the expressway fog early warning system in China mainly includes the antifog early warning system based on transmission-type visibility meter
System and scattering formula visibility meter early warning system.But all there is deficiencies.Firstly, most of the weather monitoring device in China is from state
Outer import, equipment is comparatively more expensive, and maintenance is got up also highly difficult；Secondly, airfield equipment design arrangement is also inadequate
Rationally, each province, city when building highway due to geographical status, in terms of factor lack it is careful and careful
Investigation, research, discussion, cause: installation position, the layout density of the airfield equipments such as changeable-message sign, visibility meter
The effect in practical application is not achieved, so collected data just lose availability and authenticity.Along with due to meteorology
The operation and maintenance of the relevant devices such as monitoring is improper, and many weather monitoring devices is caused not play its due effect really.
Therefore, the highway in China substantially or uses traditional artificial detection, manually to traffic in managing foggy weather
It carries out complete artificial or the semi-artificial technical measures and means such as dredging.
Therefore, safely and effectively expressway fog early warning and inducible system are established, by the mist early warning of the group of reasonable selection and
The installation position of inducible system scientifically plans layout density in conjunction with the weather Meteorological along highway, is reached with expectation
To the variation of the real-time and accurate information feedback round-the-clock meteorology of highway, real-time and accurate information is informed in time
Highway user, the safety traffic under sight information guiding, the generation of traffic accidents is reduced or avoided.It is whole
Set system has the characteristics that real-time, efficient, warning effect etc. is obvious, if using on investment highway, can be effectively solved
Expressway fog early warning and induction problem, have great social benefit and economic benefit.
