The embodiment of technical solution of the present invention is described in detail below in conjunction with attached drawing.Following embodiment is only used for
Clearly illustrate technical scheme of the present invention, therefore be intended only as example, and the protection of the present invention cannot be limited with this
Range.
It should be noted that unless otherwise indicated, technical term or scientific terminology used in this application should be this hair
The ordinary meaning that bright one of ordinary skill in the art are understood.
As shown in Figure 1, a kind of stealthy safe examination system suitable for open ground provided in this embodiment, including:Coil, magnetic field
Detection device, processing unit.Coil can generate stable magnetic field, magnetic for generating magnetic field after leading to upper alternating current in coil
Field direction is as shown, the region of magnetic field covering is formed detection zone.Detector for magnetic field is for detecting the magnetic field
Variation, specifically, when the magnetic field that coil generates changes because of extraneous interference, the magnetic field detection that is arranged in field region
Device once detects that the variation in magnetic field will export electric signal.Processing unit is used to handle the signal of detector for magnetic field output
And it alarms.
Wherein, coil can be laid on crowded open ground region, such as railway station square, park inlet, airport
Inlet, shop entrances, school inlet etc..The size of coil reaches as high as 7 meters × 2 meters of rectangular area, certain coil
It can also be other shapes, do not limit excessively herein.The size of coil can also with the increase of energized power in coil and
Increase, if ensure that coil can generate enough magnetic field, and electric current is in the range of safety, so that it may increase the ruler of coil
It is very little, to expand detection zone.
The operation principle of stealthy safe examination system is:When the detection zone that the people for carrying metallics is covered by magnetic field
When, the magnetic induction line of metallics meeting cutting magnetic field causes the variation in magnetic field, detector for magnetic field to detect the variation output in magnetic field
Corresponding signal, processing unit analyze the signal received, carry out early warning or alarm.
Stealthy safe examination system provided in this embodiment suitable for open ground, compared with existing detector gate, rays safety detection apparatus
With following advantage:
1, it is suitable for opening, as at railway station square, park inlet, airport entrances, shop entrances, school enter
Mouthful place etc., detection zone is big, can the more people of one-time detection, particularly suitable crowded region;
2, safe examination system setting is hidden, is not easy to be found by terrorist, and Security Personnel is contributed to carry out hidden investigation, improves
Arrest success rate;
3, it can detect when offender has just enter into the inlet in crowded place, play effective early warning and make
With.
For hidden entire safe examination system, the coil of the vigilance for reducing terrorist, attacking personnel, the present embodiment is embedded
In the ground of detection zone.Correspondingly, detector for magnetic field can be arranged in detection zone overhead, can depend on building top
The structure in portion is laid, and ensures the concealment of detector for magnetic field, while ensureing detector for magnetic field in magnetic field range simultaneously
With preferable sensitivity.The specific embedded place and mode of coil and magnetic field device can be according to actual installation location determinations.
Experiments verify that coil, which is embedded in ground, can generate detection certain interference, in order to reduce detection signal
Noise improves sensitivity and the accuracy of system, and coil is erected at the overhead of detection zone, as shown in Figure 2.Coil depends on building
The structure at top is aerial to be laid with, and can be screened coil in conjunction with equipment such as lamp, the pipelines at top, can equally be ensured the hidden of system
Property, while reducing because building the interference generated to coil, improve sensitivity and the accuracy of safe examination system.Based on above-mentioned reality
Example is applied, detector for magnetic field includes at least one magnetic field sensor, as shown in Figure 1.Magnetic field sensor can be arranged in detection zone
It is empty in or on the corresponding ground in domain.
Wherein, magnetic field sensor is the device that the amount in various magnetic fields and its variation can be transformed into electric signal output, magnetic
The type of field sensor includes:Film (CPP) magnetoresistive sensor, magnetoresistive sensitivity device, eddy current sensor, magnetic liquid accelerate
Spend sensor, level sensor with magnetic liquid etc..
Based on above-described embodiment, in order to improve the accuracy of detection of magnetic field sensor, as shown in figure 3, detector for magnetic field packet
Include the multiple rows of magnetic field sensor being arranged in field region, formed array magnetic field sensor can to by pedestrian carry out it is more
Secondary detection, improves accuracy of detection.Array of magnetic field presses certain regular array, and detection range is made to cover entire detection zone
Interior, when multiple pedestrians pass through detection zone simultaneously, the pedestrian of different location can cause the changes of magnetic field of different location, therefore,
The sensor of different location has different output signals in array, at the output signal to array of magnetic field
Reason analysis, can detect more people simultaneously.
Wherein, a part of magnetic field sensor in detector for magnetic field is embedded in ground, another part magnetic field sensor
It sets up in the air, three-dimensional detection array is formed, as shown in figure 3, can further improve accuracy of detection.
Further, adjacent two rows of magnetic field sensor plug hole arrangements, specific arrangement mode can refer to Fig. 4.The row of plug hole formula
Mode for cloth forms net screen type layout, can further decrease the possibility of missing inspection.
Based on any of the above embodiments, each magnetic field sensor in system is all placed in metal box, metal box
Ground connection, to reduce the noise signal that magnetic field sensor generates the induction of human body.
The stealthy safe examination system of the present embodiment further includes camera, and camera is connect with processing unit, and camera is for obtaining
Take personnel's image by coil.It can be adopted with pinpoint a certain individual in conjunction with synchronizing by the magnetic field sensor of array
The image of collection is the macroscopic features that would know that a suspect.
The stealthy safe examination system of the present embodiment further includes warning device, and warning device is connect with processing unit.Warning device
A suspect is vigilant and taken precautions against according to the output result notice Security Personnel of processing unit, does not discover exception also in a suspect
When, tracing control just is carried out to it, and suitable opportunity is selected to arrest, realizes danger early warning, the danger that will be brought to the masses
It is near minimum.
Finally it should be noted that:The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations;To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that:Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
