Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] The method for predicting the status of the merging unit equipment in the present invention proposes a time series analysis method based on the monitoring data of the merging unit equipment status, especially the monitoring data of the laser driving current of the merging unit. In particular, according to the characteristics of the monitoring data of the normal operation state and abnormal operation state of the merged unit equipment, the arithmetic square root, variance and Dickey-Fuller test are used to analyze and evaluate whether the data conform to the characteristics of a stationary time series. On this basis The ARMA model and the ARIMA model are respectively constructed to predict the state of the merging unit equipment, and the root mean square error is calculated to evaluate the quality of the established model. The d...
