【摘要】 “海底管道内爬行器及其检测技术”是海洋资源开发技术主题下资源与环境技术领域中的一项国家海洋863攻关课题。为了全面检测管壁腐蚀情况,漏磁检测技术和超声测厚检测技术被同时采用,并整合到同一台依靠油压差驱动的在线检测爬行机上。由于时间紧、任务重,课题组采用了采集卡设计和信号处理同步进行的策略。泰克数字示波器便成为在实验室进行数据分析和处理的理想选择。本文讲述了在实验室中如何运用TDS3052B示波器采集超声信号的历程以及使用心得。更多还原

【Abstract】 The crawling robot in seabed pipeline and detection technology" is a National Ocean Super 863 Key Project about resource and environment technology under the topic of exploiting ocean resource. In order to roundly detect corroding status of the pipeline wall, detection through Magnetic Flux Leakage and detection through Ultrasonic Wavelet are carried out at the same time, and these two technologies arc integrated into a on-line crawling detection robot driven by oil pressure difference between the beginning and the end of the crawling robot. Because of short time limit for the heavy project, the project group has decided that design of signal acquisition card and analysis of data must be carried out simultaneously. So Tektronix oscilloscopes become an i-deal selection for analysis and processing of data. In this paper, it is introduced that how to acquire ultrasonic signal with TDS3052B oscilloscope.更多还原
