Description
Technical field
The invention belongs to traffic circulation control technology fields, are related to a kind of intelligent anticollision early warning system.
Background technique
In recent years, as China's economy continues to develop, expressway construction is also being advanced by leaps and bounds.But at the same time, due to
Highway maintenance bring traffic accident also greatly increases.
The common cause of accident as caused by highway maintenance mainly has the following: (1), construction marker do not advise
Model: setting area is too small, excessively close, and construction marker is not complete, outmoded, unintelligible etc..(2), the factor of driver: due to highway
Totally-enclosed, full-overpass, road conditions are good, and when vehicle driving does not need driver and takes too many measure, cause under driver alertness
Drop.Driver dynamic eyesight is decreased obviously when running at high speed, and effective field of view narrows, and may be found that too late or root to necessary information
Originally a possibility that can't find, leading to error in judgement in traveling increase, or it is panic to sudden danger, and treatment measures are improper
It causes to make mistakes.
And the warning system of common setting mainly uses concave and convex lenses, traffic warning mark prompt, belongs to passive type
Safety devices cannot actively warn danger；It is influenced, can not be played a warning role completely by external environment light.
Therefore, how to solve the above problems, be those skilled in the art the content of important research.
Summary of the invention
To overcome the deficiencies in the prior art described above, it is an object of that present invention to provide a kind of intelligent anticollision early warning systems.
In order to achieve the above objects and other related objects, the present invention provides a kind of intelligent anticollision early warning system, including anticollision
Vehicle, radar detection unit, data processing terminal, controlling alarm plate and warning device；The bumper car stops being located at road construction area
The edge in domain, and close to normally travel lane；The radar detection unit includes wide area radar detector, the wide area radar inspection
