Description
Technical field
The present invention relates to the wireless anti-cheating implementation methods of anti-tampering technology field more particularly to a kind of active detection type.
Background technique
There is the place of examination just to have cheating, the behavior of cheating has just always existed since examination activity is born, from ancient times to the present,
Present high-tech profession stream is simply sent to from simple and unsophisticated, miscellaneous cheating activity emerges one after another, miscellaneous cheating device
Material is dazzling, with regard to the differentiation of cheating activity and the anti-fight practised fraud.
In the prior art, first generation cheating equipment and anti-cheating equipment: regular handset.When mobile phone just comes out, by
Many young man's favors are arrived, wherein having most of is all student race, attracting their major function is SMS function.So having
A little extreme students' unions of idea this part in examination, using short message convenience and mass-sending property can some examination hall wantonly
The a large amount of paper answer of transmission that meaning is acted recklessly obtains examination high score, interferes normal order of taking an examination.National standardization examination point by
During step construction promotes, with popularizing for audio-video inspection system, it is desirable to it is practised fraud with this clumsy information transfer means of mobile phone,
It is infeasible in comprehensive monitored picture.Be not found on mobile phone using such big-movement answer of leafing through, it is several
Having become one kind can not;Meanwhile the appearance of mobile phone shielding instrument gives mobile phone cheating deathblow, in addition administration tube
Reason means grant (many examinations do not allow examinee's carrying mobile phone, are otherwise regarded as disadvantage processing), so that mobile phone cheating is almost
It eliminates.Second generation cheating equipment and anti-cheating equipment: voice class cheating equipment and character type cheating equipment.These two types cheating equipment
Transmission frequency point in the range of 50MHz-1800MHz.It needs to carry one very with sound in early stage voice class cheating equipment examinee
With long receiving antenna is placed on, so instead there have been metal detectors, anti-cheat sensor for cheating equipment.Their purposes is to examine
When raw admission, so that it may find to carry the examinee of cheating equipment by metal detector, and in examination process, can also lead to
Anti-cheat sensor is crossed to find the examinee to practise fraud on the spot.But as cheating one's share of expenses for a joint undertaking industry constantly expands, their technology is also stepped into
High-technicalization.Such as they change the shape of voice class cheating cheating equipment, keep antenna more small, metal detector is not allowed
Easily it is found.And it is also proposed character type cheating equipment, making material first is not metal, has been changed to rigid plastics, secondly
Reception mode becomes character information, is similar to beeper used in those early years people, can send in several seconds a large amount of
Script.And anti-cheat sensor can not listen to character information, so substantially having abolished metal detector and anti-cheat sensor
Effect.Third generation cheating equipment and anti-cheating equipment: miniature version receiver and high-power transmitter device.Grain of rice earphone is
Carry out improved in voice class cheating equipment in the early time, its receiver becomes more miniature and hidden.And sending device is more
Add intelligent and powerful, realizes the unattended transmitting of high-power transmitting signal.From it is current it is understood that the case where, from
In the frequency range of 50MHz-1800MHz, the molecule that is likely to be practised fraud is as audio transmission and Digital Transmission.So,
On the market there have been full frequency band shielding device, this kind of full frequency band equipment has certain effect when just going out, but due to full range
The defect of section equipment itself operating mode causes cheating one's share of expenses for a joint undertaking to study it, just will appear described in analysis of cases the inside
Like that, the operating mode for seeing clearly the anti-cheating equipment of examination point in advance, in examination process, to examining by way of changing and practising fraud frequency point
Examinee in sends script.So full frequency band equipment is obviously unable to satisfy the requirement of present cheating prevention and control, in order to protect
The regular turn for hindering examination needs a kind of high-tech product of devices blocks that can practise fraud to all professions in a hurry in the market.
