An Efficient Scheduling System for Complex Tasks in a Digital Twin System

Abstract

The invention discloses an efficient scheduling system for complex tasks of a digital twin system. The system is suitable for Virtex-5-series FPGA chips of the Xilinx company, and comprises the stepsof designing a digital twin system complex task attribute definition module, whereinthe module completes task attribute definition from the four aspects of task resource occupation, arrival time, execution time and deadline time; designing a complex task scheduling double-cache module of the digital twin system, and finishing caching of tasks arriving in batches by the module so as to calculate scheduling priorities of the tasks at the same moment, and finishing re-scheduling of tasks failed in previous scheduling under the constraint of a certain scheduling frequency; and designing a digitaltwin system complex task schedulability judgment module, completing task scheduling priority calculation by the module, and performing task scheduling according to the scheduling priority. The problemthat the emergency task cannot be immediately scheduled can be solved to a certain extent, and the complex task scheduling efficiency of the digital twin system is improved.

Description

technical field [0001] The invention belongs to the fields of electronic engineering and computer science, and in particular relates to an efficient scheduling system for complex tasks of a digital twin system. Background technique [0002] Technologies such as equipment health control, process simulation analysis, and production line operation status monitoring driven by digital twins have been widely studied by domestic and foreign scholars, enterprises, and institutions, and are currently in the stage of practical application. The development of intelligent manufacturing has played a positive role in promoting. One of the key enabling technologies in digital twins is the fusion of data and models, the fusion of heterogeneous equipment at the bottom of manufacturing, data fusion between production lines, and different equipment models (mainly referring to certain behaviors, rules, and physical constraints behind the 3D model. ) fusion is a very complex system, including t...
