The invention discloses a low-order wheel polygon identification method and device. The method comprises the following steps: acquiring detection data of different speed grades of a detection train detected by a rail detection system; according to the power spectrum density data in the detection data, judging whether the train has a wheel polygon or not; when the judgment result is that the wheel polygon exists, the detection data deviation values of different speed grades are calculated; and according to the detection data deviation values of different speed grades, the polygon order of the wheel is judged. The method can realize low-order wheel polygon identification, and is high in efficiency and accuracy. 本发明公开了一种低阶车轮多边形识别方法及装置，该方法包括：获取通过轨检系统检测到的检测列车的不同速度等级的检测数据；根据所述检测数据中的功率谱密度数据，判断检测列车是否存在车轮多边形；在判断结果为存在车轮多边形时，计算不同速度等级的检测数据偏差值；根据不同速度等级的检测数据偏差值，判断车轮多边形的阶数。本发明可以实现低阶车轮多边形识别，效率高，准确性高。
