Quick architecture method and device for digital twin workshop system

Abstract

The invention provides a quick architecture method for a digital twin workshop system, which comprises the following steps: forming a process file with workshop production logic and manufacturing procedures according to extracted dynamic process data of a manufacturing workshop, and constructing a logic data model of the workshop according to the process file; collecting geometric model data of amanufacturing workshop through an embedded data controller and the like, and finishing geometric data modeling of the digital twin workshop through a geometric modeling method; transferring the geometric model data from a CPU memory to a pre-allocation cache region of a GPU based on a shader coding mode, and presetting coordinate transformation of a geometric model in a twin space through matrix transformation; and enabling the CPU to send a graphic rendering instruction to the GPU while calculating the dynamic logic data, so that the GPU interacts with the geometric model data of the pre-distributed cache region in multiple batches. According to the invention, the dynamic logic data and the geometric model data of the twin system are subjected to parallel computing, so that the problem ofdelay mapping of the digital twin workshop system due to large data volume can be solved.
