It is quick on the draw, it is good to debate knowledge effect for imaging clearly.Therefore, X-ray transmission imaging technique is examined in the safety to luggage and articles etc.
It is widely used in looking into.
In order to improve the inspection efficiency and percent of pass of luggage and articles, usually by the X-ray of two sets or more set same structures
Transmission checks that equipment assembling combination gets up to use.Fig. 8 is that binary channels transmission checks the overall structure of equipment and makes in the prior art
With the schematic diagram of method.Binary channels transmission checks that equipment checks that equipment is composed by two sets of identical X-ray transmissions.It connects down
To be illustrated by taking a set of X-ray transmission inspection equipment therein as an example.
Every suit X-ray transmission checks that equipment includes：X-ray machine 1 is located at the top of equipment and has front collimation device 2；
Transmission device 4 is arranged in the channel of equipment 6, to place and transmit luggage 3；And detector 5, setting are transmitting
The lower section of device 4 is simultaneously opposed with the X-ray machine 1.The X-ray that X-ray machine 1 is sent out is shaped as narrow by front collimation device 2
Fladellum penetrates after luggage 3 cross section information and is sensed by detector 5.As luggage 3 is as transmission device 4 is in channel 6
Middle movement is sequentially completed the transmission scan in all sections of luggage 3.Finally, it is adopted by number, automatically controlled and display device obtains luggage
The image of 3 (that is, tested targets).Since two sets of transmissions are checked that equipment assembly arrangement uses, set so being checked than single set transmission
Standby scan efficiency is doubled.
However, the space and weight of inspection equipment assembled in this way are big, of high cost, dismounting is laborious and uses
Get up inconvenience.Particularly, the component inside inspection equipment assembled in this way is bigger and disperses, and increases equipment itself
Volume, radiation protection region and design difficulty of processing etc..
Check that equipment is improved therefore, it is necessary to be transmitted to luggage and articles in the prior art, it is smaller to obtain
Space, lighter weight, lower cost and better simply design scheme, final realize efficiently and quickly complete to be detected
Comprehensive examination of target.

Specific implementation mode
Fig. 1 schematically shows binary channels transmission according to an embodiment of the invention and checks equipment and its user
Method.It includes that biparting beam X-ray machine 31, first checks that channel 10 and second is examined that binary channels transmission in the present embodiment, which checks equipment mainly,
Look into channel 20.The top of equipment is arranged on as the biparting beam X-ray machine 31 of core component.Biparting beam X-ray machine 31 being capable of basis
The requirement of system generates two X-ray fladellums with corresponding direction.First checks that channel 10 includes the first detector
11 and second conveyer 13.When checking the first luggage 12, the first luggage 12 is placed on second conveyer 13
On.Second checks that channel 20 includes the second detector 21 and second conveyer 23.It, will when checking the second luggage 22
Second luggage 22 is placed in second conveyer 23.Baffle 32 checks channel for separating the first inspection channel 10 and second
20.Binary channels transmission in the present embodiment checks that equipment further includes that number is adopted and processing module 43, electronic control module 42 and external interface
41 etc..
As shown in Figure 1, biparting beam X-ray machine 31 generates two X-ray fladellums, the center line of the two X-ray fladellums
It is a certain included angle.One X-ray fladellum can scan the first luggage 12 in the first inspection channel 10 (that is, tested mesh
Mark).Meanwhile another X-ray fladellum can scan the second luggage 22 (that is, tested target) in the second inspection channel 20.
The first detector 11 in first inspection channel 10 is arranged in opposite and the first transmission of biparting beam X-ray machine 31
The lower section of device 13, thus it is generally L-shaped, to increase effective area of detection.First luggage 12 is being placed to the first transmission
As second conveyer 13 moves forward after on device 13.When what the first luggage 12 reached biparting beam X-ray machine 31 goes out beam mouth
When position, biparting beam X-ray machine 31 sends out X-ray fladellum.First detector 11 sensing X-ray fladellum penetrates the first luggage 12
Section after signal.With the movement of the first luggage 12, whole transmission scans to the first luggage 12 are completed by column.

The surrounding and entrance for checking channel 10 and 20 are both provided with corresponding X-ray shield structure, and the inspection of relative closure is consequently formed
Look into channel.
Further, electronic control module 42 detects the location information of the first luggage 12 and the second luggage 22, controls two respectively
The motor pattern of transmission device 13 and 23, and in time allow and forbid sending out two X-ray fladellums.Particularly, two
It checks that channel 10 and 20 is relatively independent, can not only use individually, but also can simultaneously be used with binary channels.
Further, the beam mouth that goes out of biparting beam X-ray machine 31 is defined as fan-shaped slit.In such a case, it is possible to be not required to
Want front collimation device.It is of course also possible to external front collimation device.
Further, external control stand shows two tested object penetrating images checked in channel 10 and 20 simultaneously.It can
Regard to the transmission image generated manually look into or carry out automatic identification by software, to differentiate whether there is or not dangerous material and
It is suitably identified and alarms.
