【Abstract】 With the development of digitation and automatization of premonitory observation system,the data quantity becomes more and more rich.It is almost impossible to check and analyse the data in time completely through manpower processing.The two common methods are used;the premonitory data are processed in real-time by the ratio of long and short windows and N times mean square deviation,then an early warning about the abnormal data is given in the paper.更多还原
