随着高速铁路的快速发展，无缝线路在轨道交通领域的应用也越来越广泛，断轨的发生机率也随之变高。目前我国主要使用探伤车和轨道电路等方法检测断轨，但是存在诸多缺点。近年来，利用超声导波检测无缝线路断轨取得了长足的发展。文中设计了一种基于超声导波的断轨检测系统，具有断轨实时检测、数据上传、报警等功能，能够快速确定故障区间。在实际线路上进行了断轨检测实验，实现了以1 km为单位检测区间的断轨检测，误报率小于1%。
隨著高速鐵路的快速髮展，無縫線路在軌道交通領域的應用也越來越廣汎，斷軌的髮生機率也隨之變高。目前我國主要使用探傷車和軌道電路等方法檢測斷軌，但是存在諸多缺點。近年來，利用超聲導波檢測無縫線路斷軌取得瞭長足的髮展。文中設計瞭一種基于超聲導波的斷軌檢測繫統，具有斷軌實時檢測、數據上傳、報警等功能，能夠快速確定故障區間。在實際線路上進行瞭斷軌檢測實驗，實現瞭以1 km為單位檢測區間的斷軌檢測，誤報率小于1%。

With the quick development of high-speed rail, the CWR is more and more widespread in rail transport industry. Incidence of broken rail becomes higher than before. Detection methods such as rail flaw detecting car and track circuit have some shortcomings. The research on Ultrasonic Guided Waves has been deeply studied. Ultrasonic Guided Waves Technology has a lot of potential in the CWR track detection. A broken rail detection system based on guided wave is proposed. It can complete real-time detection of broken rails, packet upload, alarming and other functions. It can determine the fault section quickly. Broken rail detection experiments conducted in the actual line. The system can detect the rail between 1km intervals.
