Virtual-real synchronization method and system for production line

The embodiment of the invention discloses a virtual-real synchronization method and system for a production line, and the method comprises the steps: inputting the obtained first working condition data of the actual production line in a first time period into a trained LSTM model, and outputting the second working condition data at a prediction moment; third working condition data of a virtual production line at the prediction moment are obtained, whether the second working condition data are consistent with the third working condition data or not is judged, and the virtual production line is a virtual model of the actual production line; and if the second working condition data is not consistent with the third working condition data, correcting the virtual production line according to the second working condition data and the third working condition data. By adopting the embodiment of the invention, the synchronization of the actual production line and the virtual production line can be realized. 本申请实施例公开了一种
