Technical field
The present invention relates to the storage of bridge machinery data and analytical technology, more particularly, to the vector table of Bridge Crack disease
Show mode and data processing method.
Background technology
With expanding economy and the construction of road network, the volume of traffic is growing, and vehicle heavy-duty trend increases, overloaded vehicle
It is on the increase, various diseases occurs in substantial amounts of in-service highway bridge structure, wherein using crack as one of main forms.Split
The position of seam and form approximation reflect the direction of tension in concrete and concentrate position, between the reason for generation tension
In the presence of the corresponding relation for comparing determination.Therefore, Bridge Crack accurately grasps glue into concrete beam cracks such as " symptom " of patient
Characteristic, the harm for preliminary " cause of disease " for judging bridge structure and judge crack, so as to take rational Disposal Measures to rise
Vital effect；Had nothing in common with each other for the Crack Detection means and instrument of disease bridge, the crack describing mode in later stage
Also it is varied.Mainly it is indicated in traditional bridge machinery using diagram method fracture disease, it is by crack in beam body
Locus, the trend in crack, the width in crack, the length in crack, the morphological feature in crack and other auxiliary informations sign
On a schematic diagram or photo, to reach the purpose of record crack information.But above-mentioned traditional diagram method is to different records
Personnel and record time, to be difficult to unification there is standard, and a series of shortcomings such as memory capacity is big of data.In addition, using figure
Table method, the calling in later stage and analysis difficulty to Bridge Crack disease are also larger.
The content of the invention
Present invention aims at provide a kind of the vector representation mode and data processing method of Bridge Crack disease.
To achieve the above object, the present invention takes following technical proposals：
The vector representation mode and data processing method of Bridge Crack disease of the present invention be：
The vector representation mode of the Bridge Crack disease, including crack locus, the trend in crack, crack in beam body

The shape facility value in Di-crack, in advance defined in global variable, linear pattern crack -1, chicken-wire cracking -2, split
Seam -3 ... ...；
Other auxiliary paricular value information in Ei-crack, observation date, sampling mechanism or the observer in such as crack；
The data processing method is：The crack of bridge is standardized vector typing, ultimately forms crack set of vectors, base
In with CAD software interface, the calling of different modes is carried out to set of vectors M, is established basic " Medical record " of Bridge Crack disease,
Including：Distribution schematic diagram of the crack in beam body, crack are bent with the length change of time with the development schematic diagram of time, crack
Line, crack with the change width curve of time, crack with the time length change curve map.
The invention has the advantages that it is mainly shown as：
1st, the vector form that the fracture number that can be obtained to existing highway bridge detecting instrument standardizes according to this is stated, convenient to carry out computer
Storage；
2nd, because the characteristic information in crack is expressed using vector representation mode, there is standard unification, typing and easy to maintenance, storage
The advantages that capacity is small；
3rd, represented using the vector form of standardization, crack disease database can easily be established；Based on CAD software interface,
The calling of different modes is carried out to set of vectors M；Basic " Medical record " of Bridge Crack disease is established, such as crack is in beam body
Distribution schematic diagram, crack with the development schematic diagram of time, crack with the length change curve of time, crack with the time width
With charts such as the length change curves of time, the prediction for Bridge Crack disease provides scientific basis for change curve, crack.

Embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
The vector representation mode and data processing method of Bridge Crack disease of the present invention, now by taking certain circuit bridge as an example
It is described further：
Substantial amounts of transverse crack be present in the girder beam body bottom surface of the bridge；During the decade, crack inspection periodically is carried out to the bridge every year
Survey, and record archive is carried out to detection data.The vector representation mode and data of Bridge Crack disease are now proposed using the present invention
Processing method establishes the crack disease data acquisition system of the hollow slab bridge, and carries out calling and the analysis of data.
Using bridge machinery instruments such as the non-contact fracture detecting instrument in crack, three-dimensional full section scanning instrument to the 3rd of the bridge
