The invention relates to a detection method and device applied to a railway track and detection equipment, and the method comprises the steps that optical fibers are laid on the two sides of the railway track, and the method comprises the steps that first measurement signals generated by the optical fibers laid on one side of the railway track are obtained, generating a first curve based on the first measurement signal; acquiring a second measurement signal generated by an optical fiber laid on the other side of the railway track, and generating a second curve based on the second measurement signal; and obtaining the amplitude difference of the same distance in the first curve and the second curve, and detecting the railway track or a wheel passing through the railway track based on the amplitude difference. By means of the method and device, the problem that in the prior art, railway track and wheel state detection is only carried out before a train runs, and consequently the timeliness of railway track and wheel state detection is low is solved.

    本申请涉及一种应用于铁路轨道的检测方法及装置、检测设备,其中,该方法包括:一种应用于铁路轨道的检测方法,铁路轨道的轨道两侧均铺设有光纤,方法包括:获取铺设在铁路轨道一侧的光纤所产生的第一测量信号,并基于第一测量信号生成第一曲线;获取铺设在铁路轨道另一侧的光纤所产生的第二测量信号,并基于第二测量信号生成第二曲线;获取第一曲线与第二曲线中相同距离的幅值差,并基于幅值差对铁路轨道或行经在铁路轨道上的车轮进行检测。通过本申请,解决了现有技术中铁路轨道及车轮状态检测仅在列车运行前进行检测,导致铁路轨道及车轮状态检测的时效性较低的问题。
