【摘要】 通过在虚拟仪器软件LabVIEW中调用Microsoft Access数据库与Matlab软件,设计了一种基于LabVIEW的光纤安全监视预警系统,实现了对线路数据的高速采集、预处理和判决报警,同时,系统具有干涉信号的保存、回放和报警消息的GSM无线上报等辅助功能。实验证明,该系统能够对光缆线路的入侵进行有效监测。更多还原

【Abstract】 A Supervising and Early-warning system for the Safety of Optical Fiber is designed by invoking Microsoft Access database and Matlab in LabVIEW,the functions such as data-acquisition,pre-processing, decision and alarm are realized.Futhermore,the system also has the functions such as store,data-playback the interference signal and send the message of warnings by the method of wireless using GSM module.Experiments prove that the system can effectively realize the Optical fiber line Eavesdropping Monitoring.更多还原
