Method and system for quick customized-design of intelligent workshop

A method for quick customized-design of an intelligent workshop, which is applied to an intelligent workshop design system, comprising the following steps:

• step A:
• acquiring design requirement information of a production line, and performing modeling in a simulation system according to the design requirement information to establish a three-dimensional graphic model of each physical stand-alone device to be accommodated in the intelligent workshop and a workshop digital model;
• step B:
• performing action planning of each physical stand-alone device, performing logistics and motion planning of articles being processed, compiling motion and action control scripts, and performing an offline simulation operation;
• step C:
• establishing, by a digital twin technology, a communication channel among a PLC system of the workshop digital model, a PLC system of a physical workshop device and a host computer to realize interconnection and intercommunication of data and information, and realizing, by a binary synchronization technology using downlink instructions and uplink information, real-time synchronization of real-time data of the physical device, monitored data of the host computer and three-dimensional virtual simulation data to obtain a three-dimensional digital twin model of the intelligent workshop;
• and
• step D:
• outputting the three-dimensional digital twin model of the workshop as a blueprint for follow-up design and development of the stand-alone device, to a control system and an execution system;
• the step C further comprises:
• building a virtual control network, and establishing, by the digital twin technology, a physical simulation platform which is synchronized both virtually and physically so that the stand-alone device can realize action synchronization with a corresponding stand-alone digital model on a digital workshop;
• and, integrating an upper-level MES system with the workshop digital twin model to realize the operation of the whole production line under a generated MES instruction, and feeding an execution of the workshop digital twin model back to the MES system to realize an online simulation operation;
• in the step C, the method for integrating the upper-level MES system with the workshop digital twin model comprises:
• establishing, by a control network and configuration software, an instruction channel and an information channel for data interaction, and realizing, by a downlink instruction channel and an uplink information channel, connection and data synchronization of the workshop digital twin model with the upper-level MES system and an intelligent management system;
• and
• an iterative optimization step is further provided between the step C and the step D:
• a batch of orders are simulated in the MES system, to analyze the following analysis indices:
• a completion rate of the orders within a specified time limit, a balance rate of the production line, a device activation rate and a line robustness, brittleness and flexibility of the whole production line, wherein a design scheme for the intelligent workshop is further adjusted according to the analysis indices so as to optimize the analysis indices, and the above steps are executed in iterations to control the performance of the workshop.
