Description
Technical field
The present invention relates to a kind of X ray safety detection device, particularly a kind of X ray safety detection device that uses flying-spot scanner technology and backscattering technique.
Background technology
At the train station, airport, harbour, customs etc. are related to the important place of country and people's life security, all must carry out safety detection, particularly in recent years, the terrorist is movable rampant, overflow of drugs has become social effects of pollution.Therefore safety detection technology more and more is subjected to the attention of national governments.Carry out safety detection in the prior art and adopt technological means and equipment such as safety door, escape way, metal detector, case and bag detecting device, luggage parcel detecting device, drug detecting instrument usually.China be always adopt case and bag by safety door and manually the operation detection human body combine, this detection mode not only speed is slow, and separately with people and case and bag, embarrassing situations such as the aspectant socks of searching the person, undress, take off one's shoes also appear sometimes, this makes troubles for tested personnel, causes the dispute that some are unnecessary through regular meeting; Detector also can only be to the metal sensitivity in addition.Most security detection equipments adopt direct transmission scan mode simultaneously, and roentgen dose X is big, and is unfavorable to human body.How to realize hommization, finish the detection task amicably, allow people realize safety check unconsciously, both convenient, guaranteed safety again, be the technical matters that present safety detection technology is badly in need of solution.
Summary of the invention
The present invention is based on backscattering formula X ray flying-spot scanner technology, propose a kind of more convenient, the human body and the portable case and bag checkout equipment that have human nature more, more friendly, safer a kind of hommization simultaneously, not only roentgen dose X is low to make it, and can make people at simultaneously human body and case and bag unconsciously.People are more felt at ease, friendly treat safety inspection.
Technical scheme of the present invention is as follows:
A kind of human body of hommization and portable case and bag checkout equipment, contain backscattering x-ray detection device and Transmission X ray detector and frame disposal system, described x-ray detection device contains X-ray tube, collimating apparatus, flying-spot scanner drum and backscattering X-ray detector, it is characterized in that: described checkout equipment also comprises travelling belt and is used to drag the tractor of described biography band, described x-ray detection device adopts two, and relatively is placed on the both sides of travelling belt; Described Transmission X ray detector is placed on the either side of travelling belt, and this Transmission X ray detector is corresponding with the backscattering x-ray detection device that is placed on the travelling belt opposite side.
Technical characterictic of the present invention also is: described signal acquiring processing system comprises four prime amplifiers that the output signal of described backscattering X ray sensor is amplified, the mixer that four road signals after the pre-amplification are merged, and amplifier, former, discriminator, integrator, A/D and image encoder that mixed signal is handled successively; Described signal acquiring processing system also comprises the prime amplifier that the output signal of Transmission X ray detector is amplified, and the amplifier of successively signal being handled, former, discriminator, integrator, A/D and image encoder.
Backscattering X-ray detector of the present invention and Transmission X ray detector adopt plastic scintillator detector.
The present invention compared with prior art, have the following advantages and the high-lighting effect: the present invention is based on backscattering formula X ray flying-spot scanner technology, a kind of have human nature more, more friendly human body and portable case and bag checkout equipment have been proposed, use it, on the airport, embarrassing situations such as the aspectant socks of searching the person, undress, take off one's shoes can not appear in public arena such as station, both guaranteed safety, also improved tester and detected person's relation, made people be subjected to the safety detection of human body and case and bag unconsciously.This device adopts the flying-spot scanner of backscattering X ray simultaneously, and roentgen dose X is extremely low, and analyzing spot is little, and dosage is little, causes the injury of human body little.In addition owing to adopted the combination of X ray back scattering imaging and transmitted ray imaging technique, no matter be that metal dangerous material, gun, ammunition or suspicious object such as dangerous liquid material, explosive all can be detected more reliably under the clothing therefore for being hidden in.
