Embodiment

[0037] (1) Construct a multi-level twin model of all elements of the workshop

[0038] 1.1) Through the analysis and decomposition of many production elements in the physical workshop, the production elements of the physical workshop can be divided into personnel, equipment, materials, and environment, and the multi-level twin models of all elements of the workshop can be modeled separately.

[0039] Among them, the twin model of personnel includes personnel simplified model, RFID (Radio Frequency Identification) tag information, personnel location information and key operation information; specifically, personnel are workshop operators;

[0040] The equipment includes all the equipment involved in the production and processing process of the workshop, such as CNC machine tools, industrial robots, automatic guided vehicles (AGV, Automated Guided Vehicle), material transfer tables and storage platforms, etc., from multiple levels of geometry, physics, behavior, and rules , to c...

Abstract

The invention discloses a construction method of an intelligent workshop digital twin system, and belongs to the technical field of intelligent manufacturing. The method comprises the following steps: aiming at physical workshop production elements, constructing a workshop total element multi-level twin model to obtain a digital twin workshop model; constructing a data acquisition system to acquire multi-source heterogeneous data of a physical workshop, preprocessing and standardizing the multi-source heterogeneous data, and storing the preprocessed and standardized multi-source heterogeneous data into a database; by adopting the digital twin workshop model as a client and by combination with a server, achieving interaction between the digital twin workshop client and the database so that bidirectional mapping between the digital twin workshop client and the physical workshop is realized; based on three-dimensional visualization system integration, subjecting the physical workshop model and the digital twin workshop model to deep fusion interaction to finish construction of the intelligent workshop digital twin system. Therefore, the functions of real-time state display, historical state reproduction, remote control, fault alarm, state prediction and the like are achieved, and the problems that existing digital workshop data are monotonous in presentation and poor in interaction and immersion are solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and relates to a method for constructing an intelligent workshop digital twin system. Background technique [0002] With the integration and application of next-generation information technology and manufacturing such as cloud computing, Internet of Things, big data, mobile Internet, and artificial intelligence, countries around the world have successively proposed their own manufacturing development strategies at the national level to develop new models of intelligent manufacturing. In the context of the rapid development of intelligent manufacturing, digital twins have developed rapidly, and digital twin workshops have also become one of the important solutions for intelligent manufacturing. [0003] The core issue of intelligent manufacturing is to realize the integration of the physical world and the information world, and digital twin technology is an effective way to integ...
