The invention discloses a data discrimination method based on curve comparison. After obtaining the actual curves of the parameters to be judged, the reference curves of the parameters to be judged can be retrieved from the database, and the actual curves and the reference curves can be pretreated to obtain the difference sequence of the two curves, and the difference area ratio and the differenceperiod ratio of the difference sequence can be calculated, and then whether the parameters to be judged are normal or not can be judged according to the judging model. The method has the advantages of simple distinguishing feature, fast calculation speed and easy realization, and can be used in the large scale system such as rocket or satellite test, maglev train parameter monitoring and so on. In addition, the invention also provides a data discrimination system based on the curve alignment, the function of which corresponds to the method. 本发明公开了种基于曲线比对的数据判别方法，能够在获取待判参数的实际曲线之后，从数据库检索出待判参数的参考曲线，并对实际曲线和参考曲线进行预处理，得到两者的
