Reason device, for being screened to the heavy-duty vehicle interval through presently described bridge and counting, and processing data is reached described
Interval heavy-duty vehicle safe early warning main frame；Described fiber optical transceiver, for described wagon detector, described vehicle classification processor
Data communication and the heavy-duty vehicle safe early warning main frame of described interval between；Described interval heavy-duty vehicle safe early warning main frame, uses
Estimate in carrying out calculating in monitoring described bridge interval carrying situation and distribution situation to described heavy-duty vehicle, and issue corresponding
Early warning information.
Further, wagon detector is laser type vehicle checker, infrared light grid-type vehicle checker or video vehicle checker.
Further, wagon detector and vehicle classification processor are separate type or integrated form.
When further, closely, fiber optical transceiver is replaced by router or switch.
Further, interval heavy-duty vehicle safe early warning main frame is issued corresponding early warning information and is specially：To calculate and pre-
Alert result is distributed on display, notifies user of service with sound and light alarm form simultaneously.
Further, wagon detector is arranged in described bridge surface at regular intervals.
Compared with prior art, technological merit of the present utility model is：
(1) heavy-duty vehicle is estimated with distribution situation calculating in interval carrying of monitoring, finds bridge pavement driving conditions in time；
(2) according to interval heavy-duty vehicle COMPREHENSIVE CALCULATING data, safe early warning is carried out to bridge structure.
(3) this method is easy to implement, is easy to existing system and increases newly and transform.
Brief description
Fig. 1 is a kind of bridge interval of the present utility model heavy-duty vehicle safety pre-warning system pie graph.
Fig. 2 is a kind of bridge interval of the present utility model heavy-duty vehicle safe early warning main frame single interval overhaul flow chart.
Wherein：1- wagon detector, 2- vehicle classification processor, 3- fiber optical transceiver (), 4- fiber optical transceiver (two),
5- interval heavy-duty vehicle safe early warning main frame.
Specific embodiment
With reference to specific embodiment, fiber grating data demodulating system described in the utility model is done detailed further
Illustrate, but protection domain of the present utility model is not limited to this.
The utility model provides a kind of bridge interval heavy-duty vehicle safety pre-warning system.Bridge of the present utility model is interval
Heavy-duty vehicle safety pre-warning system is by wagon detector 1, vehicle classification processor 2, fiber optical transceiver 3 and 4, interval heavy-duty vehicle
Safe early warning main frame 5 forms.Illustrate, wagon detector 1 is not limited to laser type vehicle detection taking laser type wagon detector as a example
Device, flexibly can select according to actual conditions.
As shown in figure 1, laser type wagon detector 1 arranges n+1 at regular intervals in bridge floor, bridge floor detection interval is divided
Become n part, two laser type wagon detectors 1 constitute a detection interval, detect each laser by vehicle classification processor 2
Formula wagon detector 1 passes through heavy-duty vehicle quantity and compact car quantity, by fiber optical transceiver () 3 and fiber optical transceiver (two)
4 transmit and carry out data processing to interval heavy-duty vehicle safe early warning main frame 5, and will calculate and early warning result is distributed to display
On, user of service is notified with sound and light alarm form simultaneously.
As shown in Fig. 2 for a kind of bridge of the utility model interval heavy-duty vehicle safety pre-warning system bridge with single interval
Early warning controls control flow, and multiple intervals are combined in order by single interval.Control flow is described as follows：Interval heavy-duty vehicle peace
Electricity on full early warning main frame 5, system starts, and proceeds by system initialization, first wagon detector 1 starts and heavy-duty vehicle meter
Number device n1 (containing compact car equivalent heavy-duty vehicle value) resets and starts counting up, and starts timer t1 simultaneously and resets, works as t1=tJust,
Second wagon detector 1 starts and counter n2 (containing compact car equivalent heavy-duty vehicle value) resets and starts counting up, just now
Beginning finishes；Calculate this interval heavy-duty vehicle quantity n1-n2, that is, in real time according to collection heavy-duty vehicle count value and equivalent traction engine
It is this interval heavy-duty vehicle quantity that count value makees difference, and carries maximum and minimum of a value, estimation according to all types of heavy-duty vehicles
This interval all car load maximum current and minimum of a value, are converted into safe heavy-duty vehicle amount threshold, and according to this interval
Bearing requirements issue safe early warning information.
Wherein, t1 is that second wagon detector 1 starts to detect vehicle time；N1 counts for first wagon detector 1
Value；N2 is second wagon detector 1 count value；tJustFor second wagon detector 1 initialization time, need according to Interval Distance
From being configured；nExcellent、nGood、nDifferenceFor interval safe early warning threshold value.
If n1-n2=n, if n=0, show interval no car, bridge is in good condition.If n>0, and n>nExcellent, show interval vehicle
Negligible amounts, bridge is in good condition；If n>0, and n>nGood, show that interval vehicle is normal it is proposed that strengthening monitoring；If n>0, and n>
nDifference, show interval vehicle fleet size more it is proposed that taking measures.
How interval heavy-duty vehicle detecting system is combined in order by single interval heavy-duty vehicle detecting system, and control flow is
A upper system for detection section is output as the input of next system for detection section, can be extended to multiple system composition Large bridges
Beam heavy-duty vehicle safety pre-warning system.
Compared with prior art, the demodulation of this fiber grating data is fiber grating data demodulating system in the present embodiment
System it is a technical advantage that：
By carrying and distribution situation calculating estimation in monitoring interval to heavy-duty vehicle, discovery bridge pavement driving shape in time
Condition, according to calculating data, carries out safe early warning to bridge structure it is easy to implementing and extending, is easy to existing early warning system is carried out
Update and transform.
It is understood that embodiment of above be merely to illustrate that principle of the present utility model and adopt exemplary
Embodiment, but the utility model is not limited thereto.For those skilled in the art, without departing from this
In the case of the spirit of utility model and essence, various modifications and improvement can be made, these modifications and improvement are also considered as this reality
With new protection domain.
