报告摘要:Modern industrial plants generally consist of multiple manufacturing units, and the local correlation within each unit can be used to effectively alleviate the effect of spurious correlation and meticulously reflect the operation status of the process system. Therefore, the local correlation which is named as spatial information here should also be taken into consideration when developing monitoring model. In this study, a cascaded monitoring network (MoniNet) method is proposed to develop monitoring model with concurrent analytics of temporal and spatial information. By implementing convolutional operation to each variable, the temporal information which reveals dynamic correlation of process data and spatial information which reflects local characteristic within individual operation unit can be extracted simultaneously. For each convolutional feature, a sub-model is developed and then all the sub-models are integrated to generate a final monitoring model. Based on the developed model, the operation status of the newly collected sample can be identified by comparing the calculated statistics with their corresponding control limits. Similar to convolutional neural network, the MoniNet can also expand its receptive field and capture deeper information by adding more convolutional layers. Besides, the filter selection and sub-model development in MoniNet can be replaced to generalize the proposed network to many existing monitoring strategies. The performance of the proposed method is validated using two real industrial processes. Illustration results show that the proposed method can effectively detect process anomalies by concurrent analytics of temporal and spatial information.
