Abstract

The invention discloses a radio system for preventing cheating on exams, which belongs to the fields of radio spectrum monitoring and radio interference. The system comprises radio monitoring equipment and signal interference equipment, wherein the radio monitoring equipment and the signal interference equipment are split; the radio monitoring equipment is connected with at least one piece of signal interference equipment, and transmits information such as signal frequency and the like to the signal interference equipment after detecting a cheating signal; and the signal interference equipment transmits a corresponding interference signal. The system adopts a discovery way so as not to cause interference to normal communication signals in an examination room like an interference suppression method; one piece of radio monitoring equipment can correspond to a plurality of pieces of signal interference equipment to realize full spectrum band interference to the signals; and cheating information is stored in a database so as to achieve the technical effect of high pertinence.

Description

technical field [0001] The invention relates to an anti-cheating system for radio examinations, which belongs to the field of radio frequency spectrum monitoring and radio interference, and is a system for preventing cheating using radio signals in examination rooms, and is especially suitable for various large and medium-sized examinations. Background technique [0002] In recent years, there has been a phenomenon of using various radio test cheating tools. Cheaters often hire gunmen to enter the test room, and within a period of time after the start of the test, the test questions will be sent out of the test room through wireless image transmission, and then people will be organized to answer the questions, and finally the answers will be sent to the test room. It is transmitted to candidates in the examination room through radio signals. Some sophisticated radio technologies are being increasingly applied to cheating in exams, which seriously violates the exam law and un...
