Description
Technical field
The utility model relates to a kind of pavement behavior mobile monitoring equipment, especially relates to a kind of express highway pavement climate condition mobile monitoring equipment.
Background technology
China's highway mileage constantly increases in recent years, and the diastrous weathers such as dense fog, heavy rain, ice and snow have become the principal element that affects traffic safety and efficiency.Due to the impermanence of road Changes in weather, add the various specific geological states of highway, the special weather situations such as rain, snow, group's mist that are very easy to regularly produce rapidly part in short-term or when long on road, this meteorological condition is difficult to obtain by the forecast of meteorological department, and driver runs at high speed at highway, owing to can not get early warning, know nothing for road ahead situation, can not take corresponding preventive measure, very easily knock into the back and collision accident.In addition, expressway speed is higher, once because visibility reduction causes traffic hazard, often can cause chain reaction, finally forms the severe traffic accidents that many cars collide continuously, the dead group of group hinders, and has greatly affected the traffic safety of highway.According to statistics, because affecting the traffic hazard causing, the inclement weathers such as thick fog account for the more than 1/4 of total number of accident.
In order to guarantee the coast is clear, improve the processing power for accident, person can accomplish in time, accurately, intactly collect the information such as the weather conditions (particularly visibility index) of road, all kinds of anomalous events and issue in time various early warning guidance informations just to require road management, improve trouble-saving ability, accelerate to process the reaction velocity of abnormal traffic events.In the time there is meteorological sudden change and traffic abnormity, can determine in time location of accident or the regional location that is obstructed simultaneously, and the corresponding induction of real-time release and rescue information, thereby the safe and smooth of road farthest guaranteed.
At present, the mode that domestic and international similar highway is mostly laid meteorological check point and video surveillance point by employing along the line at road in Mechatronic Systems gathers weather information and video image information, and pass to the video image at center by visual inspection and the mode of weather data is carried out monitoring management by the monitor of Surveillance center, when taking treatment measures after the event of noting abnormalities and terrible weather situation, patrolled to assist discovery accident and to process along the line driving by road administration personnel timing simultaneously.
But this mode exists following deficiency:
1, weather information can only long-range prediction, and forecast data out of true cannot show the Practical Meteorological Requirements situation in each section.At present, in highway area along the line, obtaining mainly of weather information forecast by the integral point of meteorological department, and meanwhile, during expressway construction, the meteorological measuring station of laying along the line at road and visibility detector complete the auxiliary collection of weather information.Due to affect visibility mist formation, continue and the process that dissipates is affected by multiple condition, it is carried out to prediction and detection exactly and remains at many technical barriers.Simultaneously because highway is wire trend, and the forecast of meteorological department to be large region wide scope forecast is generally take square kilometre as unit, data redundancy is very large, only there is macroscopical universality and large time domain generality, and do not possess practicality and the real-time of the microcosmos area of highway.In addition, meteorological measuring station and the visibility detector of laying along the line in Expressway Electromechanical System, as: the traditional meteorological optical range instrument that detects at present principle based on the scattering of light forward/backward, it is limited that it detects sample space, principle is that the air regime in the region in tens of square metres using equipment mounting points is as collection source, mainly according to the accurate measurement to atmospheric extinction coefficient (or light attenuation coefficient of atmosphere), according to Koschmider principle, existence function relation draws visibility data between meteorological optical range MOR and extinction coefficient σ.But these data can not truly represent the extraneous visibility situation of detecting sensor, but in application, artificially this data are calculated and used as the visibility data of several kilometers or tens of kilometer range, if while just there will be thus the mounting points of visiometer and fog-zone to have larger space difference, the data of visiometer just can not reflect the situation beyond its sensor sensing range at all.The reasons such as the price of while due to meteorological measuring station and visibility detector is very expensive, maintenance cost is high, complicated operation, be difficult to the intensive laying along road, article common one, the highway of 100 kilometers can only be installed 2-3 cover visiometer, because website is relatively less, and many observation websites from highway away from, the road conditions that not necessarily can represent highway are meteorological live, therefore can not meet the demand that expressway weather detects completely.
2, current supervisory system is artificial passive monitoring mode.Need with the naked eye remove to observe monitor by monitor staff, judge with acquired information by people's brain, if there is no manual observation, will fail to report weather conditions.More or less a hundred CCTV road monitoring camera has been installed on road, and image has also all passed to Surveillance center, but can not be equipped with the monitor of same quantity and the monitor staff of same quantity realizes man-to-man keeping an eye on simultaneously.Take a road monitoring branch center as example, generally only have 10-20 platform monitor and 1-2 name staff, so can not accomplish that Jin Bai road image monitored incessantly by artificial 24 hours simultaneously.Therefore, the parking that is difficult to find in time to produce in road, drive in the wrong direction, the abnormal traffic events hidden danger such as article are dropped, and an often trickle negligent supervision and the laissez-faire and expansion that all may cause hidden trouble of traffic off one's guard even finally leads to freeway traffic major accident and causes immeasurable loss.
Summary of the invention
The utility model has designed a kind of pavement behavior mobile monitoring equipment, and the technical matters of its solution is that existing highway Shang road table temperature information cannot reflect in real time accurately.
In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
