[principle of work of utility model]
1. drugs/explosive detection subsystem work principle
As shown in Figure 1, be the profile of drugs, explosive, radiomaterial and metallics inspection door.Pilot lamp 21 is used for indication and is examined pedestrian's several states of living in: checking (amber light)/free time (green light)/warning (red light).As shown in Figure 3, air compressor 17 provides gases at high pressure, gases at high pressure is provided for air nozzle 43 by draft tube, and the Jet Stream of every group of air nozzle 43 all passes through 7 controls of a high-speed electromagnetic valve/electric rotating machine.Air nozzle 43 is installed on the air jet system, is with 29 driving air jet systems to move up and down along riser guide 28 by air jet system lifting motor 31 synchronously by the air jet system lifting.Touch-screen/computer system 27 is controlled by parts such as 19 pairs of air jet system lifting motors 31 of electrical equipment control screen, high-speed electromagnetic valve/electric rotating machine 7, air compressor 17, centrifugal blower 40, fans 1.
Glass door (option) 24 is installed in checks passage 23 both sides, can select dress according to actual needs.
When beginning to check, pilot lamp 21 shows idle (green light is bright), and it is good that checked pedestrian enters the assigned address station of checking passage 23; That system begins is jet, blow, and the particulate that blows off on one's body from tested personnel is collected; The filter screen of collecting station 13,36 turns to filter screen detection station 10,33 by the filter screen rotary tray motor on the filter screen rotating disk mechanism 12,35 11,34 and detects after collection work is finished; 9,32 pairs of filter screens of filter screen well heater that filter screen detects station 10,33 heat, suck and carry out check and analysis by drugs, explosive detection instrument 3,55 after the particulate that adsorbs on the filter screen is gasified, analysis result is delivered to touch-screen/computer system 27 and is handled, and is presented on the screen.If find the vestige of Poison or explosive, then give the alarm pilot lamp 21 warnings (blinking red lamp) simultaneously; Can thing if do not find, then this is checked and finishes, pilot lamp 21 shows idle (green light is bright), waits for entering of next tested person.
2. radiomaterial detection subsystem principle of work
Checked pedestrian enters the assigned address of checking passage 23, and native system will begin startup work prior to drugs/explosive detection subsystem, and after drugs/explosive detection subsystem finished one-shot measurement work, this subsystem finished this surveying work again.
Detect γ, n ray by radiomaterial detector 4, and the signal that detects is analyzed.Detection data is finally delivered to touch-screen/computer system 27 and is processed and displayed.If detected radiomaterial, system will send alerting signal.
3. metal detection subsystem work principle
Fig. 2, Fig. 5 and Fig. 6 are seen in metal detector 45 installation sites.When tested personnel when checking passage 23, metal detector 45 is surveyed it, result of detection is delivered to touch-screen/computer system 27 by communication modes and is shown.If detected violated metal, system will send alerting signal.The detection sensitivity of metal detector 45 can be provided with on request.
In a word, the detection subsystem of three kinds of functions combines, and can finish simultaneously and check drugs, explosive and radiomaterial that the pedestrian carries and the task of violated metal, has improved checking efficiency.
