水声信号监测系统设计与实现

Design and Implementation of Underwater Acoustic Signal Monitor System

该系统采用虚拟仪器技术、游标测量技术、声信号检测分离技术等关键技术,本着试验测控装备体积小、重量轻的原则,采用VC++、Lab VIEW编程软件实现信号的采集、实时显示及事后频率处理、回放,实现对水声信号的监测与观察,对水声设备试验中各参试设备工作是否正常作出判定,为试验中的异常情况提供了强有力的分析结果,避免评定结果出现争议。

This system uses virtual instrument technology,cursor measurement technology,acoustic signal detection and separation technology and other key technologies,in line with the principle of small size and light weight of test and control equipment,VC++\LabVIEW programming software is adopted to realize signal acquisition,realtime display,frequency processing and playback afterwards,to realize the monitoring and observation of under acoustic signals.A judgment is also made on the normal work of each participating equipment in the equipment test,and a strong analysis result is provided for the abnormal situation in the test,and the dispute of the evaluation result is avoided.
