Abstract
The invention discloses an intelligent system for monitoring icing on pavement and a monitoring method thereof. The intelligent system comprises a fisheye camera, a road icing detector, a signal controller and a display terminal. The input ends of a roadbed temperature sensor, an air humidity sensor, a vibration sensor and a pavement conductivity probe are respectively connected with the input end of a detection control circuit, and the output end of the detection control circuit is connected with an input end of the signal controller. The output end of the fisheye camera is connected with another input end of the signal controller, and the output end of the signal controller is wirelessly connected with the display terminal. The intelligent system prevents error detection according to detection of pavement conductivity, roadbed temperature, air humidity and vibration above the pavement in combination with image acquisition of the fisheye camera.

Description
Technical field
The present invention relates to a kind of intelligent monitor system for highway pavement icing and monitoring method, belonging to icing detection systems technology field.
Background technology
If surface temperature is lower than 0 DEG C, road there will be accumulated snow or icing phenomenon.Icy road readily occurred in November to a period of time of next year April (i.e. winter and early spring)., usually there is icy road phenomenon in the northern area of China, especially the Northeast and northern territory, the Inner Mongol.
Icy road early warning signal divides three grades, respectively with yellow, orange, red represent.When road table temperature is lower than 0 DEG C, precipitation occurs, when being likely to occur, in 12 hours, icy road that traffic is influential, icy road yellow early warning signal will be issued.Now, human pilot should be noted that road conditions, safety traffic, and pedestrian goes out as far as possible less by bike, notes anti-skidding；Meteorological department issues the orange early warning signal of icy road, it was shown that road table temperature, lower than 0 DEG C, precipitation occurs, is likely to occur the icy road that traffic has considerable influence in 6 hours.Now, the department such as traffic, public security to carry out icy road emergency according to responsibility, and human pilot must take non-skid feature, travels at a slow speed, pedestrian go out attention anti-skidding；When issuing icy road red early warning signal, it was shown that be likely to occur in 2 hours or the icy road that traffic is had a significant impact has occurred.Now, the department such as traffic, public security notes commander and dredges driving vehicle, closes eisbahn traffic if desired, and personnel's minimizing of trying one's best is gone out.
Icy on road bring very big harm to normal use of road, national wealth and people's lives and properties will be caused heavy losses if it occur that process not in time after freezing.
At present, the major measure of the process icy on road of China is Road Weather monitoring station, and also some area and section begin with icing early warning system.Wherein weather monitoring station monitoring accuracy is poor, function singleness, can only carry out the collection of pavement state data, it is impossible to give warning in advance, implement effect poor, it is also difficult to avoid because system accuracy problem exists wrong report phenomenon.
It addition, severe traffic accidents can often be there is in road surface icing.Southern snow disaster such as 2008 causes heavy losses to the security of the lives and property of the country and people, judge now that the road surface of the highway vision still relying on people that whether freezes goes judgement, due to ground ice condition in time, position is different, there is very big-difference in the ice-like that disappears condition, first the place of wheel process disappears ice, two tracks ask that the middle road surface of sun finally disappears ice, overhead and bridge difficulty especially disappears ice, middle road surface disappear ice time the frozen water that produces still can arrive the place of wheel process, therefore vision is relied on to determine that travel speed can only arouse attention under obvious icing condition, and the above-mentioned dark ice occurred and local ice sheet can still result in beyond thought accident and occur.
Chinese patent discloses the method for several detection icy on road, and one of which is " roadway freezing point monitoring system and method ", and its application number is CN02827284.6, adopts active cooler, temperature sensor, sampled well to constitute.And judge the apparent freezing point of liquid with conductive change according to the temperature of liquid in sampled well.The method decides whether to freeze mainly through the temperature and two conditions of conductivity judging road surface, still suffers from certain erroneous judgement.
It addition, use under this specific condition of highway pavement, the booty such as sewage and dust, by severe jamming, works according to optics, and false detection rate raises, and actual popularization and application are limited.
