The invention relates to the technical field of rail transit, in particular to a turnout curve and reference curve alignment method and device. According to the method, the problem of turnout curve alignment can be solved, and the method is more accurate when abnormity is detected by using other original methods after alignment. Meanwhile, the numerical value finally calculated by the method provided by the invention can also be used as an abnormal curve judgment standard, and an abnormal curve of an unlimited fault type can be found out. According to the invention, a curve alignment thought is given; a distance calculation mode is given, and the mode can avoid accumulative errors caused by sampling errors due to different sampling moments of sampling points during curve sampling; according to the anomaly detection method for the turnout curve, the anomaly curve which is not limited by the fault type can be found out. The invention discloses a system for curve alignment and anomaly detection based on an autonomous and controllable domestic CPU computer and a domestic operating system running environment.
本公开涉及轨道交通技术领域,特别涉及一种道岔曲线与参考曲线对齐方法及装置。本公开可解决道岔曲线对齐问题,对齐后使用原有的其他方法检测异常时,会更加精准。同时也可以使用本公开给出方法最后算出的数值也可以作为异常曲线判断标准,可以找出不限故障类型的异常曲线。本公开给出了一种曲线对齐思路;给出了一种距离计算方式,这种方式可以避免因为曲线采样时因为采样点采样时刻不同,而导致的采样误差而引起的累积误差;给出一种道岔曲线的异常检测方法,可以找出不限故障类型的异常曲线。本公开基于自主可控的国产CPU计算机和国产操作系统运行环境下的曲线对齐并进行异常检测的系统。
