Embodiment Construction

[0038] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0039] Functions such as operating status, key station operating status, assembly process monitoring, production process simulation and optimization, etc., realize effective management of the workshop operation process, comprehensively improve the management and control capabilities of the intelligent workshop, and calculate the actual assembly process through real-time simulation of the workshop operating status. According to the progress deviation of each work step, the final assembly process is adjusted according to the work step deviation, the process flow is further optimized, the station beat is balanced, and the assembly capacity of the station is improved to improve the efficiency of the final assembly.

[0040] Adjust the final assembly process according to the deviation of the working steps, further optimize the process, balance ...

Abstract

The invention discloses a production process simulation optimization method based on digital twinning based on the flexible production requirements of multiple varieties, small batch and variable paces. A manufacturing operation management system and a data acquisition and control system based on big data are constructed; the intelligent level of production logistics and the professional level ofgeneral assembly process equipment are improved, a general assembly intelligent workshop with a batch product pulsation production line and a developed product intelligent general assembly unit as main bodies is formed, and more optimization decisions are provided for physical entities through information fusion and data interaction between virtual models and the physical entities.

Description

technical field [0001] The invention belongs to the technical field of simulation optimization, and in particular relates to a digital twin technology. Background technique [0002] The final assembly of existing large and complex products usually adopts a fixed station, and manual vertical assembly is performed based on a rigid frame. The assembly quality is unstable, the assembly efficiency is low, the labor intensity of the workers is high, and the assembly operation management is difficult. [0003] Pulse Assembly Lines (Pulse Assembly Lines) originally derived from Ford's mobile car production line, is the transitional stage of the continuous mobile assembly line. The difference is that the pulsating assembly line can set a buffer time and does not have high requirements for the production cycle. When a problem occurs in a certain production link, the entire production line can not be moved, or it can be left to the next station to solve it. When the assembly work is co...
