Abnormal radio signal monitoring method and device and radio monitoring device

Abstract

The invention applies to the field of radio monitoring and provides an abnormal radio signal monitoring method and device and a radio monitoring device. The method comprises the steps of taking levelvalue data of a radio signal of any frequency in a preset signal level range as a main analysis source and averagely dividing the level value data of the radio signal of any frequency in the preset signal level range into a plurality of fragment analysis sources according to a preset signal level interval; carrying out statistics on the occurrence times of each level in each fragment analysis source, thereby acquiring the maximum occurrence times and the minimum occurrence times; calculating a ratio between the maximum occurrence times and the minimum occurrence times in each fragment analysissource; and judging a radio signal of the frequency corresponding to the fragment analysis source of which ratio is greater than a preset ratio as a triggering signal, namely, an abnormal radio signal if the ratio is greater than the preset ratio. According to the method, the device and the radio monitoring device, a potential difference signal can be found out reasonably, rapidly and accurately,which is particularly important to examination room monitoring and activity guarantee. The method, the device and the radio monitoring device adapt to the future development trend of the radio monitoring.

Description

technical field [0001] The invention belongs to the field of radio monitoring, and in particular relates to a monitoring method, device and radio monitoring equipment for abnormal radio signals. Background technique [0002] With the development of modern communication technology, the means of cheating in exams are constantly being refurbished, increasingly high-tech, and showing a trend of specialization and groupization. Cheating and anti-cheating will have a protracted new contest, which will also challenge the traditional exam management model. High-tech cheating methods are not only used in judicial examinations, college entrance examinations, social certificates and qualification demonstrations, but also in various colleges and universities, which seriously damages the fair and just examination environment and brings great negative impact on society. The high-tech cheating means in all kinds of examinations mainly use radio technology to cheat. Therefore, it is immine...
