Concealed earphone is applied to monitor the unlawful practices such as other people privacy, examination hall malpractices by a few molecules in society, to social band
Great harm is carried out, and the principle for the competition that is unfair.
The existing concealed earphone detector that cheats at one's exam is merely able to detect the position of determining examinee, to cheating take an examination into
When row processing, due to the factors such as mismatch of examinee, it is difficult quickly to inquire exam information, it has not been convenient at the later period of examinee
Reason is easy to have an impact the examinee very in examination.So cheating concealed earphone, and energy can either effectively be detected by developing one kind
Enough devices for directly inquiring examinee information, are necessary, and can be used in the example for the behaviors such as whether examinee sits in the right seat
Row inquiry.
Summary of the invention
The utility model passes through the support of magnetic field vector sensor and network communication module and remote data base, can visit
While comparing raw cheating concealed earphone, examinee information is fast and accurately positioned, so that cheat at one's exam detection and punishment and one,
Whether the present apparatus can also be sat in the right seat for examinee, if impersonate, if the customary inquiry of the behaviors such as nominal reference reaches
To the effect of a tractor serves several purposes.
To achieve the goals above, the utility model is achieved through the following technical solutions: described cheating at one's exam is hidden
Shape earphone detector includes sensor 1, controller 2, shell 3, antenna 4, display screen 5, warning circuit 6, the sensor 1 with
Controller 2 connects, and 1 input terminal of sensor is connect with antenna 4, and controller 2 is connect with display screen 5 and warning circuit 6, display screen 5
It is installed on 3 front of shell, sensor 1, controller 2, warning circuit 6 are installed on inside shell 3, and antenna 4 is installed on shell 3
End.

Preferably, the warning circuit 6 includes audio drive circuitry 7, buzzer 8, the audio driven input terminal
It is connect with 2 output end of controller, audio driven output end is connect with buzzer 8.
Preferably, the concealed earphone detector that cheats at one's exam further includes network communication module 9, remote data base 10,
The network communication module 9 is connect with controller 2, and network communication module 9 uses GSM/GPRS communication module, remote data base
10 preserve examinee information, and network communication module 9 is connect by wireless network with remote data base 10.
The utility model the utility model has the advantages that
The utility model passes through the support of magnetic field vector sensor and network communication module and remote data base, can visit
While comparing raw cheating concealed earphone, examinee information is fast and accurately positioned, so that cheat at one's exam detection and punishment and one,
Whether the present apparatus can also be sat in the right seat for examinee, if impersonate, if the customary inquiry of the behaviors such as nominal reference reaches
To the effect of a tractor serves several purposes.

Specific embodiment
Below in conjunction with the embodiment of the present invention and attached drawing, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
As shown in Figure 1, the concealed earphone detector that cheats at one's exam includes sensor 1, controller 2, shell 3, antenna
4, display screen 5, warning circuit 6, the sensor 1 are connect with controller 2, and 1 input terminal of sensor is connect with antenna 4, control
Device 2 is connect with display screen 5 and warning circuit 6, and display screen 5 is installed on 3 front of shell, sensor 1, controller 2, warning circuit 6
It is installed on inside shell 3, antenna 4 is installed on 3 upper end of shell.The sensor 1 uses three vector geomagnetic field sensors 1,
Three sensors 1 are installed in a triangle inside shell 3, and three sensors 1 are connected respectively at controller 2, inside concealed earphone
Contain metal, signal in band when concealed earphone communication with the outside world around concealed earphone can interfere earth's magnetic field more.
The warning circuit 6 includes audio drive circuitry 7, buzzer 8, the audio driven input terminal and controller
The connection of 2 output ends, audio driven output end are connect with buzzer 8, and the bigger explanation of the geomagnetic field variation that controller 2 is adhered to more is leaned on
