摘要
基于USB AE模块的便携式声发射仪是一种新型的声发射检测设备。阐述了采用声发射方法检测管道泄漏的原理、USB声发射设备的结构和特性,分析了现有USB声发射检测系统存在的局限性。以Visual Studio C++作为程序开发平台,设计了针对管道泄漏这一特定环境和对象的便携式USB声发射检测系统。通过管道泄漏模拟试验,验证了系统设计方案的合理性,实现了声发射信号采集、数据处理和声发射源定位等功能。
Portable USB acoustic emission device is a new type of acoustic emission testing equipment. This paper describes the principles of using acoustic emission to detect pipeline leaks and the structure and characteristics of the USB AE, analyzes the limitations of the existing USB acoustic emission detection system. Based on the above-mentioned points, we have developed a Portable USB acoustic emission detection system for pipeline leak on Visual Studio C＋＋ 2012 software platform. By pipeline leakage simulation experiments, we verify the system design is feasible. And the system can achieve the acoustic emission signal acquisition, data processing and acoustic source locating functions.
