Description
Technical field
The utility model relates to a kind of backscattering formula ray scanning pick-up unit, relates in particular to a kind of novel flying spot body-scanner, belongs to social safety inspection and safety precaution technical field of measuring equipment.
Background technology
Along with the safety case in the intensive and mobile big place of personnel such as bus station, railway station, airport receives increasing concern, utilize transmission and the backscattering character of X ray, with linear sweep with receive again by signal processing unit and the signal of the gathering various scanister that to handle final reading scan testing result be ultimate principle have been obtained development at full speed and obtained very using widely.Usually such pick-up unit is placed on the porch of public arena; The luggage of process, case and bag towards or pick-up unit dorsad; The X-ray beam of emission scans it according to preset rules from device, after transmission or backscattering, is received by detector, and then is handled by signal processing unit; Show by display terminal that more experienced personnel can be in the other supervision of display terminal with timely discovery suspicious object.In the existing technology, in order to reduce the radiation injury that scanning device causes personnel to be detected and adopt the backscattering formula.Backscattering formula scanner is to utilize the ray shoots information that backscattering is returned on object to carry out measurement processing, and then calculates image and a kind of device of information of the interior species distribution on this inspected object top layer.The radiographic source of this device can adopt isotope or X ray, can use flat bundles scanning also can adopt flying-spot scanner during scanning.When adopting flat bundles scanning, x ray irradiation x dosage is bigger than normal, thereby influences health.At this moment, adopt the flying-spot scanner method to address this problem well.The principle of flying-spot scanner technology is to form satisfactory bar-shaped beam through the X ray that the flying spot generating means sends x-ray source to project on the object to be scanned, and the flying spot generating means comprises that mainly a fan-shaped collimating apparatus and the collimating apparatus outside, a surperficial ad-hoc location are provided with the disk or the cylinder of slit.For example; March in 2004 disclosed CN1207558C Chinese invention patent on the 31st instructions in a kind of like this backscattering formula X-ray scanning appearance based on flying spot technology is just disclosed, comprise x-ray source, flying spot beam generator, fan-shaped collimating apparatus, detector and signals collecting and disposal system.The major technique characteristics are that flying spot beam generator adopts a rotatable cylindric straight line flying-spot scanner structure; On the same circumference of cylinder, evenly have 1 to 4 circle or square aperture; Lead or heavy metal shield layer are enjoyed in its inboard; X-ray source and fan-shaped collimating apparatus all are arranged in the cylinder, and adopt special detector.This scanner through a mechanism that the flying spot beam generation apparatus is risen by pre-set velocity, is realized the scanning from the foot to the crown to human body to the mode of human body employing transversal scanning.This scanner has characteristics such as radiation is little, efficient is high, simple in structure; But owing to be the mode of transversal scanning; Obviously greater than the human body of lateral dimension, the scanning of accomplishing one whole needs the time in about 8 to 10 seconds, considers huge personnel's flow in public arena such as railway station etc. for longitudinal size; The scanning of accomplishing a people with the time more than 8 seconds is a kind of scan mode of suitable poor efficiency, and this has also caused the practicality of this scanner to reduce.Need a kind of novel scanner that can realize quick scanning.
The utility model content
The utility model provides a kind of simple in structure, novel flying spot body-scanner that scan efficiency is high for solving the technical matters that exists in the known technology.
The know-why of the utility model is: original flying spot body-scanner receives the technical limitation of the X-ray tube that is adopted, and can not be too big on the subtended angle of flying-spot scanner, is generally 40 °.This has just caused a problem, and the subtended angle of flying-spot scanner is too little, in limited distance can be inswept scope just very little, can only satisfy transversal scanning requirement usually to human body.Adopt after the new X-ray tube; Because its outgoing subtended angle is very big, reached more than 80 °, institute's inswept scope of ability has just increased in limited distance like this; For example X-ray tube is when 1 meter left and right sides of human body; The scope of its scanning just reaches 1.8 meters to 2 meters, and is suitable with the height of human body just, becomes possibility with regard to the mode that makes the longitudinal scanning human body like this.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: novel flying spot body-scanner comprises base and is fixed in the framework of its upper surface, is connected the flying spot generating means on the said framework and is positioned at said flying spot generating means dead ahead, is arranged side by side and middle two detectors that leave the slit; It also comprises power supply and measuring circuit module and signal Processing and display terminal; Said flying spot generating means is horizontal to be fixed on the said framework; Said detector height is 1.8 to 2.2 meters; On the base of said detector outside, also be provided with travelling belt, the traffic direction of said travelling belt is parallel with the main body of said flying spot generating means.
The utility model can also adopt following technical scheme:
Said power supply and measuring circuit module are positioned on the said framework.
Said flying spot generating means comprises x-ray source and is fixed in the fan-shaped collimating apparatus in its dead ahead; Also be provided with the cylinder that inwall studs with the heavy metal shield layer at the said x-ray source and the fan-shaped collimating apparatus outside; Said cylinder is connected on the said bolster through bearing; Also be provided with slit on the same circumference of the sidewall of said cylinder, said slit also is provided with drive motor over against said fan-shaped collimating apparatus at the rear of said cylinder.
Said slit is positioned at the openend of said cylinder.
Said slit number is 1-4.
Said cylinder is a metal material.
Said drive motor is a servomotor.
Be positioned on the said bolster and also be provided with the power lead inlet on the outer wall of said x-ray source one side.
Advantage and the good effect that the utlity model has are: because the flying spot generating means is horizontal is fixed on the framework, cancelled original elevating mechanism, the utility model simple in structure.Scan mode becomes longitudinal scanning from transversal scanning; Because the longitudinal size of human body is obviously greater than lateral dimension, the time of accomplishing single pass has also shortened widely, has promoted the efficient of scanning; Have outstanding meaning for the big occasion of flows of the people such as railway station, airport, practicality is stronger.
