Abstract

The invention provides an unmanned warehouse logistics optimization system based on virtual production. An intelligent warehouse keeper system, a PLC control system and a virtual production system are connected in sequence; the intelligent warehouse keeper system, the PLC control system and a real production system are connected in sequence; the intelligent warehouse keeper system is used for independently driving a virtual production model to act for production trial operation, so as to observe the logistics trend and the equipment action in the virtual production system and output an index capable of evaluating the operation efficiency; the intelligent warehouse keeper system is further used for driving the virtual production model and a real production site to act at the same time, predicting a link capable of being optimized in the virtual production system, outputting the index capable of evaluating the operation efficiency, and counting and analyzing the field operation condition. Through real-time interaction between the intelligent warehouse keeper system, the PLC system and the virtual production model, trial production can be carried out under a new condition, a high-load condition or other conditions, so as to evaluate the production process; virtual production and actual production can be controlled to be conducted synchronously; and the logistics link capable of being optimized can be mined, so that the logistics is more smooth.

Description

technical field [0001] The invention relates to the technical field of virtual production, in particular to an unmanned warehouse logistics optimization system and method based on virtual production. Background technique [0002] The use of computer models to plan / simulate the manufacturing process and production equipment configuration plans breaks through the limitations of traditional experience-based planning, thereby improving equipment utilization and operating state stability, and ensuring more reliable product quality. [0003] With the progress of society and technological innovation, there are many variable factors in modern logistics production, such as logistics distribution system, production scheduling system and planning and scheduling system, etc. It is difficult to complete these tasks through the human brain. [0004] Patent CN101872161A discloses a virtual reality-based interactive control method for key equipment in the process industry, including the fol...
