Method for monitoring content of free acid in aluminum material chromate-free passivation process based on digital twin

Abstract

The invention provides a method for monitoring the content of free acid in an aluminum material chromate-free passivation process based on digital twinning, and belongs to the field of digital twin. The method comprises the following steps that: a system three-dimensional model is established in a digital twin human-computer interface of a digital space; a digital twin information processing module extracts system state information from a database and a knowledge base and transmits the system state information to the digital twin human-computer interface module; a control unit of a physical space collects information data of a process site input device in the current round in real time and compares the information data with information data of a previous round, if the information data changes, a change signal is generated; the database stores the change signal and then sends the change signal to a data processing module; and a mobile terminal receives data stream information, generates corresponding intervention information and sends the corresponding intervention information to the digital twin human-computer interface module. According to the method, through a digital twinning simulation process, in the free acid content monitoring process, the knowledge and technology threshold of workers is lowered, and meanwhile the monitoring quality is guaranteed.

Description

technical field [0001] The invention relates to the field of digital twins, in particular to a method for monitoring free acid content in a chromium-free passivation process of aluminum materials based on digital twins. Background technique [0002] Digital twins are more and more widely used in the field of intelligent manufacturing. Digital twins make full use of data such as physical models, sensor updates, and operating history, integrate multi-disciplinary, multi-physical, and multi-scale simulation processes, and complete the mapping in the virtual space to reflect the entire life cycle process of the corresponding physical equipment. To put it simply, a digital twin is to create a digital "mirror image" on the basis of a device or system. It is based on the physical design model of the ontology, the data of the ontology sensor and the historical data of the ontology operation, and is a dynamic simulation of the ontology object. The chromium-free passivation process ...
