Abstract

The invention relates to a method and system for monitoring the working condition of an injection molding machine during the plastic injection molding process. The method comprises the steps that an injection molding machine working condition data set is received; the injection molding machine working condition data set comprises multi-dimension working condition data collected during plastic injection molding by the injection molding machine; on the basis of the multi-dimension working condition data, a curve graph is generated, and on the basis of multiple curve parameters in the curve graph, a sample set is generated; a machine learning model is used for carrying out learning training on the sample set, and a training result is obtained; according to the training result, whether the working condition of the injection molding machine is in the abnormal state or not can be monitored; through the curve graph, the multi-dimension working condition data are converted into the curve parameters, the dimensions of the multi-dimension working condition data are reduced, when the machine learning model is used for carrying out learning training on the curve parameters, the machine learning model overfitting can be effectively overcome, and the controllability of monitoring of the working condition of the injection molding machine in the plastic injection molding process can be improved.

Description

technical field [0001] The invention relates to the technical field of working condition monitoring, in particular to a method and system for monitoring the working condition of an injection molding machine during plastic injection molding. Background technique [0002] With the continuous evolution of industrial automation, the integration and complexity of injection molding machines continue to increase. Plastics are non-Newtonian fluids, which have complex physical and chemical properties, many variable factors, and strong coupling, resulting in low controllability of the injection molding machine production process. Abnormalities occur frequently, so timely and effective monitoring of the working conditions of the injection molding machine can provide an important production guarantee for plastic injection molding. [0003] At present, the working condition of the injection molding machine mainly uses the monitoring model to monitor the working condition data of the inje...
