Description
Technical field
The present invention relates to the explosives detection techniques field, the device that particularly a kind of letter bomb detects.
Background technology
World today's terrorist incident constantly takes place, and except that airplane hijacking, airplane crash incident, exploding car and body bombs, the terrorist also utilizes high explosive and the detonator mail of packing into to plot to murder city father and noted public figure, to cause political fallout.Be generation and the guarantee people property safety of eliminating these incidents, national governments all are devoted to research and develop the technology that can detect hiding explosive effectively.
In numerous explosives detection techniques, technology with conventional X-radial imaging technology for detection explosive, need operating personnel rule of thumb to judge, but dangerous goods such as explosive can be made different shape, this gives by image and judges have Free From Explosives to bring great difficulty, and is powerless especially at a small amount of explosive of hiding in the mail.Utilize neutron detection method, need well protect, be unsuitable for the use of key departments equipment.Draw by analysis-by-synthesis and to utilize nuclear quadrupole resonance (NQR) principle to carry out explosive to detect and have certain advantage various detection methods, it is a kind of method that is similar to fingerprint detection, have "dead", do not destroy detected article, can accurately discern the advantage of explosive.
The explosives detection techniques of nuclear quadrupole resonance (NQR) principle is a kind of emerging Detection Techniques that grew up in recent years, remains the technology that belongs to highly difficult in the world.In the world, it is reported and have only the Russia and the U.S. to develop the letter bomb pick-up unit, but their pick-up unit all is to adopt the split design, and display interface adopts pilot lamp or be connected with computing machine and show display interface complexity and not directly perceived.Adopt the research of the device of explosive in the NQR technology for detection mail still to belong to blank at home, do not see disclosed bibliographical information.
Summary of the invention
The present invention has overcome deficiency of the prior art, and the mail explosive detection apparatus of the integral type that a kind of volume is little, testing result is directly perceived, effective, simple to operation is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of mail explosive detection apparatus comprises rack, controller, radio-frequency power amplifier, signal condition and control box, and key is that shielded box is arranged in the rack, and display screen is installed on the rack.
The present invention is all right:
Described display screen is the touch-control display screen.Described rack is made by anti-electromagnetic interference (EMI) material, and universal wheel is installed in the rack below.Described controller is produced with reception transaction card, data collecting card, stepping motor control card by radiofrequency signal to be formed.Described shielded box is made up of matching network module, tuning capacity, detecting chamber, and detecting chamber twines detecting coil outward.Described signal condition and control box are made up of signal condition module, low-tension supply, harmonic ringing processing module, step motor drive module.
Compared with prior art, the invention has the beneficial effects as follows: this device adopts shielded box to be arranged on the interior integrated structure design of rack, integrated level height, reduced the volume of equipment, structure connects and gathers, attractive in appearance, and display screen is installed on the rack, make simple to operation, intuitive display as a result.Rack adopts anti-electromagnetic interference (EMI) material to make, and antijamming capability is significantly strengthened.Rack below installation direction wheel makes things convenient for moving of equipment.Display screen adopts the touch-control display screen, operates easylier, and display interface is attractive in appearance.This device is easy to use, and testing result and to the "dead" pollution of surrounding environment, is applicable to domestic and international key departments accurately and reliably.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Referring to Fig. 1 and Fig. 2.Mail explosive detection apparatus of the present invention comprises rack 1, controller 10, radio-frequency power amplifier 9, signal condition and control box 8, and shielded box 7 is arranged in the rack 1, and display screen 5 is installed on the rack 1.
Referring to Fig. 3.Being inserted with radiofrequency signal in the controller 10 and producing and reception transaction card 17, data collecting card 18, stepping motor control card 19, is the control center of equipment.
Referring to Fig. 4.Shielded box 7 comprises matching network module 20, tuning capacity 21 and detecting chamber 6.The detecting chamber 6 outer detecting coils 22 that twine.Detecting chamber 6 has the detecting chamber door 12 that is installed in the rotating band shielding action on the anti-electromagnetic interference (EMI) rack 1, and conveniently tested mail 16 putting into and taking out.
Referring to Fig. 5.Signal condition and control box 8 comprise signal condition module 23, low-tension supply 24, harmonic ringing processing module 25, step motor drive module 26.Finish the tuber function and the signal condition of equipment.
Referring to Fig. 6.The workflow of equipment is: the main power switch 2 of at first opening equipment is given power devices, then opens the critical piece of starting switch 3 starting outfits, makes their work, and critical piece comprises: touch-control display screen 5, radio-frequency power amplifier 9, controller 10.Open loaded switches 4 after touch-control display screen 5 has information indicating, at this moment equipment can detect mail.
At first tested mail 16 is put into detecting chamber 6, close detecting chamber door 12, after using touch-control display screen 5 to select measuring ability, controller 10 obtains the tuning information of harmonic ringing processing module 25 by data collecting card 18, finishes tuning by the control tuning capacity 21 of stepping motor control card 19, step motor drive module 26, stepper motor 13 after treatment.After tuning the finishing, controller 10 produces with reception transaction card 17 control radio-frequency power amplifiers 9 by radiofrequency signal and sends radio-frequency pulse, pulse is added to detecting coil 22 by the matching network module 20 in the shielded box 7, be used for encouraging tested article, tested article after the excitation send the signal of nuclear quadrupole resonance (NQR) frequency, signal is detected coil 22 and picks up, the signal that picks up is sent into controller 10 through signal condition module 23 conditioning backs by data collecting card 18 and is handled, analyze, and the result is presented on the touch-control display screen 5, at this moment finished detection to tested mail 16.Open detecting chamber door 12 interchangeable other mails, do another time detection.
This device can carry out the whether detection of implicit explosive to various letter class mails under the situation of not opening mail, for the safety of key departments provides safeguard, and harmless bad to detected article.
The present invention is not limited to above-mentioned embodiment, no matter does any variation on shape or structure, as shielded box 7 is installed in outside the rack 1, link into an integrated entity with rack 1, and all be a kind of distortion of the present invention, then the present invention also is intended to comprise these changes and is out of shape interior.
