Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings the anti-terrorism safety inspection method for explosive according to the embodiment of the present invention and the anti-terrorism rays safety detection apparatus for explosive is described in detail.
As depicted in figs. 1 and 2, according to the anti-terrorism safety inspection method for explosive of the embodiment of the present invention, comprise the following steps:
Step S1: form air-flow, to blow to the personnel 500 by security check passage 100 on the security check passage 100 limited.
Be understandable that, security check passage 100 can be located at the comparatively open and place of limiting hardly such as railway station square, porch, park, airport entrances place, shop entrances, school porch, and the endpiece of security check passage 100 leads to the places such as railway station, park, airport, shop, school.
Such as, in the both sides of security check passage 100, exhaust fan 210 is set, 220 equipment such as grade, to blow to the personnel 500 by security check passage 100.
In addition, in step S1, in the horizontal direction, described air-flow at least covers security check passage 100, in the vertical direction, and the height of described air-flow is from the ground of security check passage 100 upwards 1.2 meters ~ 2.0 meters.Thus, can ensure that air-flow fully blows to for the personnel 500 by security check passage 100.
Step S2: collect the molecule and/or particle that blow off from personnel 500 with it.
In the explosive component of explosive, no matter solid shape or liquid, all can discrete go out some fine particles or gas molecule (passing through volatile form).Under the effect of air-flow, these molecules and/or particle can by the human bodies that blows off.Now, can such as asepwirator pump 300 or similar devices be passed through, collect these molecule blown off from personnel 500 and/or particles with it.
Step S3: the molecule that detecting step S2 collects and/or particle.
Such as, these molecules and/or particle can be detected by chromatograph, to know the composition of these molecules and/or particle.
Step S4: when detect the molecule and/or particle blown off with it from personnel 500 containing explosive molecule and/or particle time, export the determination information that these personnel are a suspect.
Described explosive molecule and/or particle at least comprise following one: petrol molecule, kerosene molecule, alcohol-gasoline blend, ammonium nitrate molecule, trinitro-toluene or C4 slurry explosives particle.
In other words, when human body keeping explosive, in the explosive component in explosive always discrete go out some fine particles or gas molecule.By forming air-flow at security check passage, these discrete explosive molecules out and/or particle are blown off human body.By collecting and detecting the molecule and/or particle that blow off from human body, if these molecules and/or particle contain explosive molecule and/or particle, namely these personnel of identifiable design may hide explosive by body.
Step S5: send early warning after step s4.Now, safety inspector obtains early warning signal, can carry out the further measure such as search the person to a suspect.
As shown in Figure 2, in order to realize the anti-terrorism safety inspection method for explosive according to the embodiment of the present invention, the present invention also proposes a kind of anti-terrorism rays safety detection apparatus for explosive, comprising: air-flow forming unit, explosive detection unit and controller (not shown).
Specifically, air-flow forming unit is used on security check passage 100, forming air-flow, to blow to the personnel 500 by security check passage 100.
As shown in Figure 2, air-flow forming unit comprises multiple first row fan 210 and multiple second row fan 220.Multiple first row fan 210 intervals are arranged in the first side of security check passage 100, and multiple second row fan 220 intervals are arranged in the second side of security check passage 100.
Explosive detection unit for collecting the molecule and/or particle that blow off from personnel 500 with it, and detects the molecule blown off with it from personnel 500 collected and/or particle.
Explosive detection unit specifically comprises: asepwirator pump 300 and chromatograph 400.Asepwirator pump 300 for collecting the molecule and/or particle that blow off from personnel 500 with it, and by the molecule blown off with it from personnel 500 collected and/or particle transport to chromatograph 400.Chromatograph 400 is for detecting the molecule and/or particle that blow off from these personnel with it.
Advantageously, chromatograph 400 is gas chromatograph or liquid chromatograph.Such as, asepwirator pump 300 is connected with the absorption gas column of gas chromatograph, and the molecule blown off with it from personnel 500 collected and/or particle heat rapidly in absorption gas column, concentrate release gas, are equivalent to sensitivity and improve hundred times to several ten thousand times.Primary adsorption, the such as open source information of U.S. SANDIA National Laboratory; Secondary absorption, the volume that the PHASED technology of the PHASED (gas chromatography that the world is minimum) of such as HONEYWELL, current HONEYWELL is used for gas detect have 1 cubic inch large; PHASED technology is for replacing HPLC (liquid chromatography that the world is minimum), and the volume that HPLC is used for gas detect has 2 cubic inches greatly.
Described controller is connected with explosive detection unit, for when detect the molecule and/or particle blown off with it from personnel 500 containing explosive molecule and/or particle time, export the determination information that these personnel are a suspect.Namely, if when chromatograph 400 detects that the molecule that blows off from personnel 500 and/or particle contain the materials such as petrol molecule, kerosene molecule, alcohol-gasoline blend, ammonium nitrate molecule, trinitro-toluene or C4 slurry explosives particle with it, described controller exports the determination information that these personnel are a suspect, and sends early warning further.
According to the anti-terrorism safety inspection method being applicable to open ground and the rays safety detection apparatus of the embodiment of the present invention; utilize the explosive component of explosive can discrete go out the characteristic of fine particle or molecule; collect and detect by the molecule of the human body that blows off and/or particle; if these molecules and/or particle contain explosive composition, then identifiable design possibility body hides a suspect of explosive.Rays safety detection apparatus is simple, safety check reliable results.
