Description
Technical field
The invention belongs to road traffic technical fields, more particularly to a kind of high-speed road conditions intelligence warning system and its work
Method.
Background technique
In the process of current city, with the emergence of boom town and the enlarging of old town, high-speed transit road also exists
Constantly construction, the vehicles number travelled on road are also quickling increase.In order to which motor vehicle can pass through on super expressway
It is safer, generally require that some warning signs or caution device are installed on some sections to inform motor vehicle driving personnel, it is special
It is not on certain specific sections, it is desirable that motor vehicle speed is limited at the velocity amplitude of a certain fixation with downward driving.Therefore, often
Some speed-limiting warning boards are placed on accident-prone road section, remind passing driver pass by this place pay attention to oneself speed and
Front is traffic accident multi-happening section.
But the driving habit and law-abiding awareness due to some drivers are thin, it is but ripe to the warning of warning sign by road
It is seen depending on nothing, therefore causes many traffic accidents that should not occur.And traditional speed-limiting warning board is substantially without intelligent function
The warning sign of energy, the only fixed speed limit mark of function, the velocity amplitude of each location speed limit is different, does not have mutual friendship
It is transsexual, without the function that real-time vehicle velocity measuring function and accident early warning are broadcasted, can not occur the section of accident to front
It proposes constrained warning, is easy to cause the generation of second accident.
Summary of the invention
The purpose of the present invention is to provide a kind of high-speed road conditions intelligence warning systems, connect a variety of acquisitions by control module
Module, acquisition module obtain sequence of video images, make the difference technology with sub- adaptation background and isolate motion diagram from background image
Picture is shown on bianry image in the form of patch, and the motion information of vehicle patch is judged using patch parser, feedback
To display equipment, solve the problems, such as that existing warning sign the degree of automation is low, does not have intelligent reminding function.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of high-speed road conditions intelligence warning system, including the light being located on the anticollision barrier of highway two sides

And traffic accident；
Step L5: the information of acquisition is sent to alarm center by wireless communication module by control module, when there is traffic
Accident is sent to first-aid centre while being sent to alarm center；
Step L6: the LED warning sign near control module control accident shows the location information that GPS positioning arrives；
Step L7: the light band near control module control road accident shows corresponding light color.
The invention has the following advantages:
(1) present invention connects a variety of acquisition modules by control module, and spacing acquisition module obtains sequence of video images, fortune
Technology is made the difference with sub- adaptation background and isolates moving image from background image, is shown on bianry image in the form of patch,
Patch is classified and polymerize using patch parser, obtains the essential information of plate, then the valve by pre-setting
Value judges the operating status of road vehicle, improves the accuracy rate of vehicle-state differentiation, and being capable of fast notification alarm
Medical staff's rescue efficiency is improved at center.
(2) present invention reminds driver to pay attention to front thing by sending accident information to the LED warning sign near accident section
Therefore section, light band colleague reduce the hair of second accident using the accident in section in front of the light prompting driver of different colours
Raw probability.
