Method for constructing virtual-real combined digital twin simulation experiment platform

Abstract

The invention discloses a method for constructing a virtual-real combined digital twin simulation experiment platform. The method comprises the following steps of: (1) designing an equipment three-dimensional model, and importing the equipment three-dimensional model into simulation software; (2) adding a motion control script and a data interface into simulation software; (3) compiling a control program of the PLC or a motion controller program of a robot, downloading the compiled control program or motion controller program to a corresponding controller for compiling and running, and running the program to obtain a data signal; (4) transmitting the data signal obtained in the step (3) to the simulation software in the step (1), performing data interaction, and driving virtual equipment in the simulation software to move; and (5) comparing the motion state of the virtual equipment with the actual programming effect of the controller to obtain a visual debugging result of the controller. According to the construction scheme provided by the invention, the development cost and the construction cost of the experiment platform can be remarkably reduced, the display effect is good, and the design debugging efficiency of a production workshop and a production line is improved.
