Description
Technical field
The present invention relates to instrument and equipment fields, and in particular to single source double-visual angle screening machine.
Background technology
Screening machine is also known as safety inspection instrument.The safety inspection based on X-ray is generally used in currently available technology
Instrument, screening machine by examined luggage is sent into X-ray examination channel by conveyer belt by the emitting of X rays, do
It relates to, capture completion inspection.
Luggage enters X-ray examination channel, can generate blocking to package detection sensor, which is sent to system
Control section generates X-ray trigger signal, triggering x-ray radiation source emitting x-ray.It is a branch of to be penetrated by the fan-shaped X of collimator
Harness passes through the inspected object on conveyer belt, and after X-ray is absorbed by inspected object, the dual energy that bombardment is mounted in channel is partly led
Bulk detector.X-ray is changed into signal by detector, these very weak signals are amplified, and be sent to signal processing cabinet do into
The processing of one step.
The throwing of usually used X-ray emitter is vertically, or from upper according to direction in currently available technology
Under, or from bottom to up.The receiver of signal acquisition is corresponding with X-ray emitter in 180 ° of settings.By means of which
The safety check image of formation is an orthographic projection two dimensional image.
Security staff judges article entrained in luggage by observing this two dimensional image.But it is such
Safety check image forming course has the following problems：
First, if its angle matches properly with X-ray direction when article passes through screening machine, after being projected by X-ray,
It will can not be accurately identified with a dotted or linear presentation, safety inspector on safety check image, it is possible to cause missing inspection；
Second, when explosive or contraband are blocked the lower section in stereochemical structure, since stereochemical structure is for explosion
Object or contraband formation are blocked, therefore automatic detection can be interfered to calculate, to reduce the accurate fixed of detection；
Third, since the projection information in a direction is less, so many articles can not be accurately anti-on safety check image
It should come out, it is possible to cause flase drop or missing inspection etc.；
4th, when article is more in luggage, each layer article overlaps in same safety check image after one direction projection, safety inspector
Judge that the time increases, also need to reinspection of unpacking in some cases, to cause safety check working efficiency low, the stream of people is slow by speed
Slowly.
In order to obtain information more fully safety check image, for example three-dimensional safety check image, has company to develop rotation at present
The X-ray emission source of formula, during safety check, X-ray emission source constantly rotates, and matched receiver equally constantly revolves
Turn, to form the safety check image of several different angles, the fitting of these data is got up using fitting algorithm, reduction forms one
3-D view, such structure can greatly reduce missing inspection, flase drop, simultaneously because image is more nearly authentic item form, institute
It is easy with safety inspector's identification.
But this screening machine requires the running accuracy in X-ray emission source very high, whole screening machine cost height, at
This height, therefore can not widely promote the use of.
Invention content
The purpose of the present invention is be directed to current injection line source there are the problem of, a kind of new single source double-visual angle safety check is disclosed
Machine improves safety check information so as to low cost, avoids flase drop, missing inspection, improves safety check working efficiency.
In order to achieve the above-mentioned object of the invention, the present invention discloses following technical scheme：
Single source double-visual angle screening machine, including X transmitters, X-ray receiver board, transport system, protective cover, further include having slit
Cylinder, the slit cylinder are arranged in the outside of X transmitters, and X-ray is emitted by the way that the slit on slit cylinder is arranged, described narrow
Two slits are offered on seam cylinder, the angle between two slits is more than 0 ° and less than 90 °, and the X-ray receiver board setting exists
At the interior upside slit projection of protective cover.
Preferably, the angle between two slits is between 0-45 °, wherein including 45 °.
Transport system is mainly made of the dynamical system of conveyer belt and conveyer belt, and article to be detected is placed on conveying
It takes.By the movement of conveyer belt, article to be detected is brought to the X-ray scanning area that X transmitters and X-ray receiver board are formed
In domain.
X transmitters are corresponding with X-ray receiver board, and X-ray receiver board is arranged in the interior upside of protective cover, and specifically sets
It sets at the projection of slit, after X-ray is launched via slit, can be received by X-ray receiver board, so as to acquire warp
The signal that X transmitters after luggage and articles interference are launched, this ray signal form corresponding safety check after acquiring, handling
Image.
In a preferred technical solution, it is 45 ° that we, which further disclose the angle between two slits,.
Meanwhile further preferred embodiment is, wherein a slit setting is in vertical direction, another slit setting
On the in-plane horizontal by 45 °.
In addition, as another preferred, it is 30 ° that we, which disclose the angle between two slits,
Correspondingly, in vertical direction, another slit is arranged in the plane horizontal by 60 ° for a slit setting
On direction.
Further comprise graphic data processor, the graphic data processor is connect with X-ray receiver board.Pass through
The X-ray diffraction image that different slits emit is fitted by graphic data processor, and being formed has three-dimensional color effect
Scanning patter.
Further, we are also disclosed the graphic data processor and are connect with display screen.At graph data
It manages device and shows the connection of screen, on the display screen by scanning patter reaction after treatment.Safety inspector can be intuitive
See the figure after fitting.
Compared with prior art, the invention has the advantages that：
First, stereo-picture can be formed by two visual angles, for the safety check instrument of traditional single-view, safety check
Image shows more comprehensive, it can be seen that bends the shape of article, and bending article blocks the article condition of lower section.
Secondly, compared to the prior art in realized for three-dimensional safety check image by rotary X-ray emission source, the present invention
Disclosed in technical solution without increasing new ray emission source, while without carrying out same axis calibration, only setting by slit
It counts to realize three-dimensional safety check image.Requirement to equipment is relatively low, can be realized with a low cost stereo-picture acquisition.
Simultaneously as technical solution disclosed by the invention can restore the stereoscopic-state of article to be detected, it is therefore, not only right
It is more accurate that the appearance of article judges, and can effectively recognize whether that article blocks, and safety check accuracy is high, and omission factor can
To significantly reduce.
Finally, it is notable that since be not necessarily to will be unlimited or close to unlimited figure for technical solution disclosed by the invention
As information is integrated, it is only necessary to the image fitting at two visual angles, therefore fit time is short.This makes safety check image acquisition time
Shorten, can effectively improve safety check and pass through flow.
The present invention can be achieved with by plane by simple structure of modification to three-dimensional safety check image improvement, to help
Safety inspector's Fast Identification article to be detected.It is the configuration of the present invention is simple, easy to use, there is very high application and popularization value.
