英文摘要：

This paper uses the change point method to establish the monitoring model of the complex data based on the multinomial distribution data.Through the numerical simulation,it is proved that the test statistic is excellent.The change point model can accurately find the position of the change point and the estimate of the change point,which can provide a strong basis for more practical application.
