Control method and system of lithium battery pole piece rolling mill based on digital twin technology

Abstract

The invention discloses a control method and a system of a lithium battery pole piece rolling mill based on a digital twin technology. The control method comprises the steps of: establishing a lithium battery pole piece rolling mill digital twin virtual model, achieving correlation of a digital space and a physical space through a novel rolling mill control system, and effectively enhancing the visualization degree when the rolling mill is operated by virtue of the constructed digital twin body to promoting the improvement of the actual control strategy and prediction and diagnosis of fault conditions. The control system comprises a control unit formed by a main control system, an information collection module, a drive module and an information transmission module, and is achieved in a mode of an embedded development board. The control method and system perform prediction of the processing process in advance to optimize the processing parameters to allow the actual processing result to meet a processing quality requirement and change the current situation that the existing control method is too lagged is changed.

Description

technical field [0001] The invention belongs to the field of intelligent control of lithium battery pole piece rolling mill equipment, and more specifically relates to a lithium battery pole piece rolling mill control method and system based on digital twin technology. Background technique [0002] The digital twin is to establish a virtual simulation model of a physical entity, combined with sensor information acquisition technology, to feed back the operation of the physical entity equipment to the established virtual simulation model, and complete the display and feedback of the behavior, rules, strategies and other information of the real environment. In order to realize the functions of system detection, process display and system optimization of the actual equipment in the whole life cycle. [0003] As a key link in the production of lithium-ion batteries, the lithium battery pole piece rolling mill is increasingly automated, and the control system is developing in the...

Problems solved by technology

Although this method can control the pole piece rolling mill equipment to carry out the rolling work of the lithium battery pole piece, there are still some problems to be optimized: the information integration ability of the control system is not strong, and the control system has limited ability to obtain information from the equipment; The feedback of the overall operation mode of the lithium battery pole piece rolling mill makes it difficult to improve and optimize the system control strategy; lacks fault prediction and analysis methods, and relies more on human observation and judgment
