On-Line EMAT Detecting System for Wheelset Tread Based on FPGA

摘要

摘要: 为了提高我国当前列车轮对的检测效率, 设计了一种基于FPGA的列车轮对踏面电磁超声在线检测系统。该系统将电磁超声检测技术与FPGA应用技术相结合, 采用基于FPGA的可编程片上系统技术, 实现了电磁超声信号发射/接收、数据采集、微弱信号检测以及存储显示等, 充分发挥了FPGA在运算速度和设计灵活性上的优势。试验表明, 系统具有较高的检测精度和检测效率, 可在列车运行速度<20 km/h时成功检测出轮对踏面上深度>2 mm的人工缺陷。

Abstract: An on-line EMAT detecting system for wheelset tread based on FPGA was developed to improve the detecting efficiency of wheelset. Combining EMAT with SOPC technology based on FPGA, this system fully took advantage of FPGA in design flexibility and processing speed. It could achieve transmission and reception of the electromagnetic ultrasonic surface wave, data acquisition, weak signal detection, storage and display. Experiments showed that the system possessed high detecting accuracy and efficiency, which could detect an artificial defect that is deeper than 2 mm on wheelset tread when the trains speed was slower than 20 km/h.
