Topological relation modeling method and device for information physical fusion system

Abstract

The invention relates to a topological relation modeling method and device for an information physical fusion system, and the method comprises the following steps: 1), building an equipment model, anddetermining an energy port, a material port and an information port of each piece of equipment and the outside; 2) connecting two or more than two equipment models together according to ports to forma subsystem model with corresponding functions, and obtaining a network model of the subsystem model according to the subsystem model; 3) connecting two or more subsystem models together according toports to form a physical system model with corresponding functions, and obtaining a network model of the physical system model according to the physical system model; 4) according to the interactionof energy and information between the controller and the external environment, defining energy and information ports between the controller and the external environment; and 5) connecting the physicalsystem model and the controller model together according to the actual connection relationship and ports to obtain a hierarchical model of the whole information physical fusion system.T he method anddevice can be widely applied to the field of information physical fusion system analysis and evaluation.

Description

technical field [0001] The invention relates to the field of cyber-physical fusion, in particular to a method and device for modeling topological relations of a cyber-physical fusion system. Background technique [0002] The cyber-physical fusion system (CPS) is the unification of computing and physical processes. The controller and communication network monitor and control the physical process, while the physical world feeds back and affects the computing process. Through the feedback loop, the deep integration and real-time interaction between computing and the physical world are realized. CPS is the close integration of virtual computing, network and physical processes in various system scales and at various system levels, and there are complex interactions of matter, energy and information among its internal components. How to describe the physical process and information network and their relationship is the basis for the analysis of CPS. For large and complex CPS syst...

However, the establishment of an industrial subsystem model based on a subsystem with a fixed topology described in this method is only a static topology between devices and cannot reflect the dynamic interaction of energy, matter, and information between devices. The description method of its topology is based on json and xml files, without mathematical definitions, cannot perform calculation and analysis of topological relationships
