摘要
研究了一种简便有效的无线电作弊防控系统,综合应用先进的无线电频谱检测与识别技术、自适应定向干扰技术和便携式全波段小区域屏蔽技术,最终实现对无线电作弊过程中向考场内发送答案环节的有效阻断,达到防止利用无线电设备进行考试作弊目的.有效打击了使用无线电通讯工具进行的集团化、网络化和产业化等团伙作案的考场作弊行为,突破现有反作弊设备的侦测受限.以逐渐形成一个覆盖整个北京市区考场的防无线电作弊的网络化防控体系.通过系统设计实现,包括监测设备和干扰设备等的应用效果显著,而且提高考务工作有效性.
The behavior of cheating in examinations has grown into gang crime, showing the characteristics of networking, collectivization and industrialization, which makes it difficult to detect cheating by existing anti cheating equipments. To combat radio cheating, a simple and effective radio cheating prevention and control system is studied, integrating the application of the advanced monitoring and recognition technology, the adaptive directional jamming technology and the portable full-band cell domain signal shielding technology, and the effective block of sending answers to exam room is eventually realized, reaching the goal of preventing radio cheating. Gradually it helps to form a prevention and control network system covering most examination-room areas throughout Beijing. Through systems design and implementation, monitoring equipment and jamming equipment and others are effective, and it has improved the efficiency of examination.
