Distributed examination room radio cheating counter measure equipment

Abstract

The invention discloses a distributed examination room radio cheating counter measure equipment, which comprises at least one examination room radio cheating counter measure central controller for detecting all radio signals within the frequency band of between 40 and 1,000 MHz in an examination room, capturing radio cheating signals, demodulating and decoding the radio cheating signals, authenticating contents of the radio cheating signals, extracting signal characteristic parameters and transmitting the signal characteristic parameters to an interference and blockage device; and the captured cheating information is stored and serves as an evidence and reported through a network. The distributed examination room radio cheating counter measure equipment comprises a detection module, a communication interface, a user interface and at least one examination room radio cheating signal interference and blockage device for receiving the cheating signal characteristic parameters sent by the central controller, forming an optimal interference style and an optimal strategy according to the parameters and producing and releasing radio interference signals. The examination room radio cheating signal interference and blockage device comprises an interference production module, a communication interface and a state management module.

Problems solved by technology

In recent years, with the development of information technology, the means of cheating in exams have undergone tremendous changes. In the past, cheating in exams was mainly entrainment, peeping, and mobile phone transmission of answers. Wireless invisible earphones, special wireless receivers and other radio transmission and receiving equipment conduct cheating activities. The number of cheating incidents has increased sharply. It affects the normal selection of national talents and damages the fairness and seriousness of national education examinations

[0003] Although some anti-radio cheating products have appeared on the market, they all have obvious defects. Metal detectors can only implement static detection of cheating equipment, and cannot intercept radio cheating signals and interfere with them; " "Cheating Ke", "Examination Master" and "Examination Dog" can only detect wireless earphone signals, so the scope of action is very limited, and they cannot intercept character-based digital radio cheating signals; mobile phone jammers are only effective for signals in the mobile phone frequency band, and cannot Covering the entire frequency band; most of the Russian radio monitoring equipment equipped by the radio management department is bulky and expensive, and can only monitor very few points, and cannot achieve large-scale deployment and application
