Embodiment 1

[0022] Such as figure 1 Shown is an intelligent workshop production and processing system based on digital twins and machine learning technology. The intelligent workshop production and processing system consists of a three-tier architecture and one module, namely the physical workshop (1) and the workshop service system (3) Connect the virtual workshop (2) and the machine learning module (4).

[0023] The physical workshop (1) of the present invention refers to the physical workshop involved in the processing of the workpiece, including parts, components, workpieces, processing equipment, materials, sensors, actuators, etc., in addition to the production and processing functions of a traditional workshop , It also has the ability to perceive access and fusion of heterogeneous multi-source real-time data; the workshop service system (3) is a collection of various data-driven service system functions, and is mainly responsible for the intelligentization of the workshop driven by th...

Embodiment 2

[0025] The intelligent workshop processing method based on digital twins and machine learning technology adopts the above-mentioned system for operation, and the operation steps are as follows:

[0026] 1) The real-time data of the physical workshop is transferred to the workshop service system, and the workshop service system generates initial production activities based on the real-time data and feeds back to the physical workshop;

[0027] 2) The workshop service system transfers production data to the virtual workshop, which simulates the operation status of the physical workshop, monitors the running time, real-time status, and number of workpieces of the machine tool, and feeds back the simulation analysis results to the workshop service system. The workshop service system optimizes the simulation analysis results based on real-time data, and transmits them to the virtual workshop again, and iterates until the production plan is optimal;

[0028] 3) Based on the obtained produc...

Embodiment 3

[0031] Such as figure 2 As shown, this embodiment first constructs a virtual workshop based on a physical workshop. The workshop service system generates a production plan based on real-time data of the physical workshop and transmits the production plan to the virtual workshop. The virtual workshop performs simulation activities according to the established production process flow. At present, the machine tool data acquisition and monitoring software is available in the workshop, which can monitor the real-time status, running time, and number of workpieces of the machine tool.

[0032] In the process of processing the workpiece, according to the different processing surfaces and the required processing accuracy, different types of machine tools such as lathes, grinders, milling machines, planers, boring machines, etc. will inevitably be used in the processing. The sequence and process planning have been simulated and optimized in the virtual workshop, which can improve the eff...

Abstract

The invention discloses an intelligent workshop production processing system and method based on digital twinning and machine learning technologies. According to the system, data of a physical workshop are transmitted to a workshop service system in real time through the digital twinning technology; a workshop service system iteratively optimizes initial resources, generates an initial productionplan, and transmits production data to a virtual workshop; the virtual workshop carries out simulation analysis and optimization on the production processing process and returns a simulation result tothe workshop service system; the workshop service system transmits a command to a physical workshop by means of process control; and the system predicts the number of workpieces needing processing based on machine learning to obtain the number of workpieces needing processing in the physical workshop. According to the invention, the simulation optimization and machine tool transfer process for workpiece production processing can be performed in the virtual workshop by using the digital twinning technology and the number of workpieces needing processing can be predicted by machine learning, sothat the resources are saved and the efficiency of product research and development is improved; and the production number of enterprises becomes reasonable.

Description

Technical field [0001] The invention relates to the field of intelligent production and processing of workshop parts, in particular to an intelligent workshop production and processing system and method based on digital twins and machine learning technology.
