Application Research Of Radio Monitoring And Suppress Technology In Exam Security

In recent years, with the rapid development of radio technics and the wide application of radio service, radio cheating in exams has become increasingly rampant. In order to prevent and combat the cheating acts in exams by using radio equipment and maintain a fair and equitable test order and airwaves order, the radio security work of exams is paid close attention by majority examination departments and radio regulatory agencies.It is worthy to study how to combine the radio technics with the exam security efficiently for better work.Looked on the present actual situation, some problems exist in the security work. This paper researches on the problems existing in practical work and demonstrate through the case. The main research contents include:1、The characteristics of technology in cheating on examination, research cheating signal discrimination method of cheating signals.2、How to improve the monitoring of the automation level of the middle frequency scanning work in the exam security work. Put forward three solutions: first, use the threshold value spectrum monitoring technology; second, use the Trigger measurement monitoring technology; third, perfect the basic databases and compare the real-time data.3、The technology of radio orientation and location. Analyze the technology of the system and equipment for radio monitoring in use. Analyze the advantages and disadvantages of several technologies of radio orientation and location. The different equipment and technology should be selected according to actual situation in exam security work.4、The radio interference suppression technology application in the practical work, summarizes the experience in the actual work and put forward an approach to suppress radio signals to cheat in the exam.
