Technical field
The present invention relates to a kind of vehicle driving safety regulation technique field, relate in particular to a kind of vehicle superelevation monitoring and prior-warning device.
Background technology
Along with fast development of national economy; Communications and transportation is busy day by day, and highway freight transportation market internal competition is fierce day by day, and some lorry owners ignore traffic safety; Pernicious wantonly out-of-gauge load; Not only upset the order of freight market, and the structural safety and the serviceable life in serious threat bridge, culvert, tunnel, the annual loading because of the vehicle superelevation causes card, hits the direct economic loss that bridge, culvert, tunnel cause the accident and reach tens million of units.Since 2004, State Council and relevant ministries and commissions put into effect multinomial measure, rectify road transport market from rules, administer lorry superelevation, overweight loading, obtain remarkable result; But bounce-back aggravation is in recent years loaded the traffic hazard that causes because of the lorry superelevation and is appeared in the newspapers repeatly.Obviously, it is imperative to administer lorry superelevation loading from the technological layer constraint.
Domestic main constraint resolution has at present:
1, traditional warning sign scheme is promptly write limit for height caveat or label at highway bridge or culvert tunnel upper.
2, metal tube limit for height doorframe detection scheme; Promptly set up the ∏ type limit for height doorframe of making by the metal tube material,, thereby realize security protection bridge, culvert, tunnel because Overheight Vehicles can't pass through the limit for height doorframe in bridge, culvert, the place ahead, tunnel.
3, infrared correlation monitoring and warning scheme; Promptly establish cement (metal) bar in bridge, culvert, driveway both sides, the place ahead, tunnel; Infrared emission and receiving trap are housed respectively on it; When lorry superelevation this place of going, blocking infrared beam report to the police (be 200710193012.0 the disclosed alarm for monitoring superelevation of vehicle of Chinese patent) like application number.
4, infrared laser diffuse reflection monitoring and warning scheme; Promptly two groups of infrared laser detecting devices are being installed above bridge, culvert, the tunnel especially highway critical point, are being crossed and block 60 meters limit for height monitoring surfaces above the driveways at a distance, go when the lorry superelevation and report to the police automatically after invading this monitoring surface (be 03119010.3 the disclosed a kind of vehicle superelevation monitoring and warning device of Chinese patent) like application number.
Such scheme all has limitation part separately:
Scheme 1 can not effectively be stopped going of Overheight Vehicles.
Scheme 2 is often because of blocking bad metal tube of damage, causing traffic jam.
Scheme 3 is influenced by snowstorm weather and irrelevant floating thing easily and causes false-alarm owing to adopt single beam send-receive mode.
Scheme 4 is in limit for height monitoring surface continuous monitoring lorry superelevation, and the early warning reliability is high, but infrared laser detecting device price is relatively costly, especially installs at culvert, tunnel and part bridge construction, calibrates trouble, often limits the use of in the highway critical point.
Summary of the invention
The object of the invention just is to overcome the shortcoming and defect that prior art exists; A kind of vehicle superelevation monitoring and prior-warning device are provided; Be a kind of can be under any highway section, any meteorological condition the monitor vehicle superelevation; The prior-warning device in protection bridge, culvert, tunnel, this device have that early warning is reliable, cheap, all advantages of easy construction.
Technical scheme of the present invention is:
A kind of Γ or ∏ font support of being made up of orthogonal cross bar and montant is set on bridge, culvert, right side, motor-driven vehicle going track, the place ahead, tunnel; Each track ultrasonic probe module is set respectively on cross bar, is used for monitoring the height of each lanes vehicle downwards; Also be provided with control module and wireless communication module, and montant is provided with acousto-optic early warning module;
Ultrasonic probe module, wireless communication module and acousto-optic early warning module are connected with control module respectively.
Principle of work of the present invention is:
Measure the distance of high-order bit to the probe of driving vehicle through the ultrasonic probe module, thereby differentiate whether superelevation of this vehicle; If vehicle loading superelevation; Control module is sent to acousto-optic early warning module to superelevation information and makes corresponding early warning literal and show and audible alarm, through wireless communication module the information of these Overheight Vehicles is sent to traffic control center simultaneously or on the traffic police's mobile phone on duty of this highway section.
The present invention has advantage and good effect:
1, early warning reliability is high, can avoid causing false-alarm mistake alert condition to take place because of irrelevant floating thing blocks probe.
2, construction install convenience only need be established a kind of support of being made up of the Γ font montant and cross bar and get final product on right side, motor-driven vehicle going track.
3, cheap, cost performance is high.
