Patent number: 11898212Abstract: A method and device for blast furnace state monitoring based on multi-modes fusion. In the process of blast furnace state monitoring, the concept of sub-mode is introduced, and the method for pre-acquisition and multi-modes weighted fusion by sub-mode is proposed to monitor blast furnace state. After preprocessing the main parameter data of the blast furnace, several sub-modes of the blast furnace and their corresponding blast furnace state indication variable data are obtained by means of a mean shift clustering algorithm. Taking the real-time parameter data of the blast furnace as inputs, the Euclidean distance between the real-time parameter data of the blast furnace and each sub-mode is calculated, and the sub-modes are weighted and fused according to the distance, and the fusion result is the real-time blast furnace state, so as to realize the real-time state monitoring of the blast furnace in a smooth operation.Type: GrantFiled: July 18, 2023Date of Patent: February 13, 2024Assignee: ZHEJIANG UNIVERSITYInventors: Xiaoyu Tang, Xin Wang, Chunjie Yang, Wenhai Wang

Publication number: 20230177313Abstract: A method for predicting burning through point (BTP) based on an encoder-decoder network is provided, which belongs to a field of soft-sensing modeling in an industrial process. A BTP prediction model based on the encoder-decoder network with a temporal attention mechanism and a spatial attention mechanism is developed according to data acquired during an operation of a sintering machine, where the temporal attention mechanism is used to characterize temporal dynamics of samples, and the spatial attention mechanism is used to capture a correlation between an object variable and an advanced feature, to improve accuracy and robustness of the model. With the model, BTP in a sintering process can be predicted in real time, which has great practical significance for on-site process guidance and parameter adjustment.Type: ApplicationFiled: June 10, 2022Publication date: June 8, 2023Applicant: ZHEJIANG UNIVERSITYInventors: Chunjie YANG, Feng YAN, Yuxuan LI, Chong YANG

Publication number: 20210365784Abstract: The present disclosure discloses a method for deriving fault diagnosis rules of a blast furnace based on a deep neural network, which relates to the field of industrial process monitoring, modeling and simulation. Firstly, a deep neural network is used to model historical fault data of the blast furnace. Then, for each kind of fault, the process starts from the output layer of the network, wherein sub-models of nodes in the adjacent layers in the deep neural network are established by using the decision tree in sequence, and the if-then rule is derived. Finally, the if-then rules are merged layer by layer, so as to finally obtain fault diagnosis rules of the blast furnace with blast furnace process variables being the rule antecedents and with fault categories being the rule consequents.Type: ApplicationFiled: May 19, 2021Publication date: November 25, 2021Inventors: Xiaoke HUANG, Chunjie YANG
