Distributed detection and positioning method for examination cheating wireless invisible earphone, and detector

Abstract

The invention provides a distributed detection and positioning method for an examination cheating wireless invisible earphone, and a detector. In the past, a supervisor needs to go to an examinee whotransmits a signal to find out the cheating. The method comprises a set of audio magnetic field signal micro detection devices, and an audio magnetic field signal micro detection device is arranged atthe position of each examinee according to the seat distribution mode of the examinees, the arrangement positions satisfy the condition that the light-emitting surfaces of the audio magnetic field signal detection devices can be observed by the supervisors, all the audio magnetic field signal detection devices are distributed to form a detection array, and when an audio magnetic field signal is generated artificially, an audio magnetic field signal drives an alarm lamp of the audio magnetic field signal detection device in the detection array to emit light, and the alarm lamp with the highestbrightness is closest to the signal source of the audio magnetic field, and the examinee at the position where the alarm lamp with the highest brightness is located carries the artificial audio magnetic field signal source. The method is applied to an examination room anti-cheating device.

Description

Technical field: [0001] The invention relates to a distributed detection and positioning method and a detection device of wireless invisible earphones for cheating in exams. In particular, the detection device is a miniature detector. Background technique: [0002] There are two main types of high-tech cheating equipment for exams, namely, cheating equipment based on viewing and cheating equipment based on listening: [0003] 1. The cheating equipment relying on viewing is to hide the display screen in various items that can be brought into the examination room, such as: pens with display functions, rulers, calculators, watches, meal cards, erasers, etc. Although these cheating equipment Pretend to be in different shapes, but you have to look at the answers with your eyes after all. This behavior of candidates looking at the answers is likely to arouse the vigilance of the invigilators. The invigilators who have received high-tech anti-cheating test management training can q...

AI Technical Summary

Problems solved by technology

This device uses a portable device to transmit audio electromagnetic waves of a specific frequency range with sufficient power as an interference positioning signal to drive the invisible earphone to work, which can effectively interfere with the positioning of the invisible earphone and solve the problem of inconvenient deployment of wired audio electromagnetic field interference equipment, but the high power Due to factors such as the diameter of the transmitting coil and power supply, the audio electromagnetic field transmitting equipment is bulky and expensive, and is not suitable for large-scale use as technical defense equipment distributed by invigilators in the examination room

[0018] To sum up, the traditional interference or search methods have certain limitations, so it is urgent to develop a new test technology for wireless invisible earphones that is very low in cost, easy to operate, accurate in identification, and suitable for large-scale use in the test room. Anti-device, effectively prevent the illegal use of wireless invisible earphones in the exam
