基于DSP的声学检测系统设计
Design of Acoustic Detection System based on DSP
摘要
Abstract
Acoustic detection is a technology that senses and analyzes the sound signal of the object,so as to nondestructive identification of its quality,state,defect and other information.It has the advantages of low cost and non-contact detection.The current acoustic detection system generally designs special sound acquisition and recognition functions for the detection target to complete specific detection tasks,lack of universality.An acoustic detection system is designed based on digital signal processor(DSP),including acoustic acquisition module and acoustic analysis software,which is suitable for a wide range of detection scenarios.It has acoustic data collection,display,analysis and acoustic detection functions,and can transmit acoustic data wirelessly or wired,which meets the need for separation of sound acquisition and analysis.In addition,it allows the user to customize a library of acoustic analysis models,and then flexibly select the appropriate acoustic model from the library in the acoustic analysis software to integrate into the inspection program to perform the detection task.The effectiveness of the acoustic detection system is verified by testing the main functions of sound acquisition,display and acoustic detection.关键词
