Because a human body stands still, artifact caused by shaking of a human body is avoided, imaging quality is high and checking process is high in comfort.

Description

Testing fixture
Technical field
The present invention relates to a kind of testing fixture, especially for the testing fixture of human body safety inspection.
Background technology
Utilize the human body safety inspection device, X ray forms scan image after penetrating human body, can in the human body body/external dangerous material/contraband goods of carrying checks.
In the human body safety inspection system; Basically be two types: one type is imaging system vertical movement scanning, and human body plants oneself, and this type systematic tested person has comfortableness preferably; But swash width is longer; Influence in order to reduce to move to imaging system simultaneously adopt lower sweep velocity usually, so the equipment inspection percent of pass is lower; Another kind of type is that imaging system is motionless, and human body stand in and carries out tangential movement on the transfer system, and this type systematic tested person's comfortableness is relatively poor, and the people who moves knows from experience and produce the pseudo-shadow of scanning, influences imaging effect.
Summary of the invention
The purpose of this invention is to provide a kind of testing fixture, this testing fixture can improve the inspection percent of pass.
According to an aspect of the present invention, the invention provides a kind of testing fixture, this testing fixture comprises: the ray generation device that is used for divergent-ray; And with said ray generation device at interval preset distance and being used to receive the detector of the ray that the ray generation device sends, wherein said ray generation device and said detector can be moving with unequal angular velocity upright axis string pendulum.
In the present invention, the tested person plants oneself, X ray generation device and detector in surface level along the human body left and right sides Width swing synchronously.Because wobble area needs only envelope tested person left and right sides width, so movement travel is short, and sweep velocity is fast, and device inspection percent of pass is high.Human body plants oneself, the pseudo-shadow of having avoided human body to rock causing, and image quality is high, and the checking process comfort level is high.Among the present invention, the human body zone of standing can be passage, can realize the through type inspection thus.
Description of drawings
Fig. 1 is the schematic front view according to the testing fixture of the embodiment of the invention.
Fig. 2 is the diagrammatic top view according to the testing fixture of the embodiment of the invention.
Embodiment
As illustrated in fig. 1 and 2, testing fixture 100 comprises according to an embodiment of the invention: the ray generation device 105 that is used for divergent-ray; And with said ray generation device at interval preset distance and being used to receive the detector 10 of the ray that ray generation device 105 sends.Said ray generation device 105 can be with 107 swings of unequal angular velocity upright axis line with said detector 10.Testing fixture 100 also comprises coupling arrangement 109, and this coupling arrangement 109 connects said ray generation device 105 and said detector 10, makes said ray generation device 105 and said detector 10 swing with unequal angular velocity upright axis line 107.Testing fixture 100 also comprises: frame 5, the bearing support block 1 that is fixedly connected with frame 5.Ray generation device 105 comprises: x-ray source bracing frame 3, x-ray source 4, fan-shaped shielding box 6 of X ray and collimating apparatus 7.Ray generation device 105 can be any suitable ray generation device.In addition, testing fixture 100 also comprises: inspection passage 8, inspection passage 8 is formed in the frame 5.Tested person 9 can stand on receiving check in the inspection passage 8.The both sides of inspection passage 8 all can pass in and out.Ray generation device 105 and said detector 10 rough alignment.
Coupling arrangement 109 comprises: vertical axes 1091, the axis of said vertical axes 1091 are said vertical axis 107; And the web member 15 that is fixedly connected with vertical axes.Vertical axes 1091 is supported by bearing support block 1 through bearing 2, and ray generation device 105 is fixedly connected with vertical axes 1091, and detector 10 is fixedly connected with said web member 15.Web member 15 can approximate horizontal extends and can be bar.
Testing fixture 100 also comprises: drive unit 120, said drive unit 120 is connected the end away from said vertical axis 107 of said coupling arrangement 109, is used to drive said coupling arrangement 109 around said vertical axis 107 swings.
Drive unit 120 comprises driving wheel 14, and said driving wheel 14 is installed in rotation on the end of said coupling arrangement 109, and through the said coupling arrangement 109 of the roll drive of this driving wheel 14, for example, this driving wheel 14 can contact with ground.Said drive unit 120 also comprises the drive source that is used to drive said driving wheel 14 rotations.Drive source can be made up of motor 12 and driving gear pair 11.Driving wheel 14 is installed in the end of coupling arrangement 109 through bearing 13.
During along arc swing, said web member 15 can be the connecting link of one at said detector 10 upright axis lines 107.
Said web member 15 can be telescopic, makes said detector 10 roughly to move along a straight line.For example, web member 15 is telescopic, and web member comprises sleeve pipe and bar, and an end of this bar inserts the sleeve pipe from an end of sleeve pipe slidably, and the other end of said sleeve pipe is fixedly connected with said vertical axes, and said bar is fixedly connected with said detector.
In the use, motor 12 drives driving gear pairs 11, and driving wheel 14 rolls, and drives 107 swings of web member 15 upright axis lines, pendulum angle envelope tested person 9 zone of standing.When web member 15 swing, the fan-shaped shielding box of x-ray source bracing frame 3, x-ray source 4, X ray 6, collimating apparatus 7, detector 10 are done synchronous swing.The X ray that x-ray source 4 sends becomes the fan-shaped plan bundle through after the collimating apparatus 7; Pass tested person 9 backs and get into detector 10 receiving areas; Detector 10 produces the electric signal corresponding with X ray intensity, periodically gathers this electric signal, and further converts digital signal to; Just can generate row and can be used for scan lines displayed, some column scan lines then generate a width of cloth scan image.
Tested person 9 plants oneself, and x-ray source 4 is swung along tested person's 9 left and right sides Widths in surface level with detector 10 synchronously.Because wobble area needs only envelope tested person 9 left and right sides width, so movement travel is short, and sweep velocity is fast, and device inspection percent of pass is high.Human body plants oneself, the pseudo-shadow of having avoided human body to rock causing, and image quality is high, and the checking process comfort level is high.
In addition, after X ray passes tested person 9, less than the receiving area width, guarantee that all rays that arrive detectors 10 are all by effective reception at the spreading width of the receiving area of detector 10.In motion process, the X ray that also will guarantee to penetrate human body all the time all gets into the receiving area of detector 10.X-ray source 4 to go out bundle mouthful, the collimating slit of collimating apparatus 7 and the receiving area of detector 10 be coplane all the time in motion process.Web member 15 both can be rigid rod shown in the drawings, also can be sliding sleeve and Slide bar structure, thereby realized in the connecting rod swing process detector 10 rectilinear motions.When web member 15 adopted sliding sleeve and Slide bar structure, detector 10 and associated fitting needed linear guide, and guide piece can be guide rail, axle or other devices.
In addition, can utilize the angle feedback signal of motor 12 rotors, take to wait move distance or equal angles to trigger the control mode of detector 10 acquired signal, also can adopt the firing control of timer isochronic interval.This instance can adopt the equal angles firing control.
Tested person 9 is in when inspection, can stand on the ramp that X ray can penetrate, thereby realizes foot's inspection.
