Abstract

The invention discloses a blocking control system and method based on a wireless cheating signal, and the system comprises N pieces of blocking equipment, a network switch, detection equipment, and anantenna. The detection equipment is connected with the network switch and the antenna. The detection equipment is used for carrying out the feature analysis of a signal obtained by the antenna, and transmitting a first control instruction to the N pieces of blocking equipment through the network switch when there is a suspected signal. The N pieces of blocking equipment are connected with the network switch. The blocking equipment is used for generating an interference signal of the suspected signal according to the first control instruction, and transmitting the interference signal. According to the embodiment of the invention, the system can intelligently adjust the radiation power according to the environment spectrum information, and solves a problem that the excessively high transmission power of pressing equipment causes the excessively large impact on the health of a human body and an excessively large management and control range.

Description

technical field

[0001] The invention relates to the technical field of wireless communication, in particular to a blocking control system and method based on wireless cheating signals. Background technique

[0002] During some major national education examinations, invigilators generally use the radio monitoring vehicle system to perform radio security tasks. The monitoring vehicle system is mainly composed of antennas, radio frequency front-ends, spectrum monitoring, and high-power suppression equipment, and is mainly used to shield external wireless cheating signals. Although the vehicle-mounted system is flexible and fast, it has a great impact on the surrounding electromagnetic environment. In order to completely cover the teaching building of the examination room, high-power transmission must be used, and it is difficult to find a good deployment location, and there are inevitably blind spots. In addition, the on-board system relies too much on the experience of profess...
