Abstract

The invention provides a testable digital twinning body modeling method for an intelligent production line, and the method comprises the steps: firstly building a three-dimensional model of equipmentin the intelligent production line through digitalized modeling software, and importing the three-dimensional model into digitalized production line simulation software to obtain an intelligent virtual production line; secondly, planning motion paths of the equipment, simulating the intelligent virtual production line to obtain simulation beats until all the motion paths are traversed, and exporting the motion path with the smallest simulation beat to construct an intelligent physical production line which is the same as the intelligent virtual production line; and finally, setting a PLC control logic scheme according to the simulation process of the intelligent virtual production line so as to drive equipment of the intelligent virtual production line to perform production action simulation, so that the production actions of the intelligent physical production line and the intelligent virtual production line are kept consistent, and the construction of the testable digital twinning body of the intelligent production line is completed. Key information and operation data of the intelligent physical production line can be reflected in real time by operating the intelligent virtual production line, the production line building and debugging time is shortened, the project period is shortened, and the project cost is reduced.
