摘要
针对目前我国超声导波检测设备的落后现状,根据超声导波检测的机理。采用新型高速单片机、模数转换芯片、高频线性功率放大电路、环状阵列压电陶瓷传感器和基于LabVIEW的数据采集软件,开发了一种集成化的小型超声导波检测系统。该系统能够在管道中激励和接收超声导波,通过对激励波及反射回波的时空位置分析,判断出管道长度及存在的缺陷。
A small uhrasonic guided wave test system for pipe is developed. According to the method of uhrasonic guided wave testing, this system contains a high speed microcontroller, a digital-to-analog conversion, a high frequency linear power amplifier, ring array PZT transducer and a LabVIEW-based data acquisition system. This system can make a actuating signal and receive the echo signal in the pipe. People can gage length of the pipe and detect the flaw in the pipe by analyzing the signal.
