The invention discloses a spatio-temporal event constructing method and a spatio-temporal event constructing device for a cyber-physical system, belongs to the technical field of information, and is used for solving the problem that implementation of a specific application is hard to support as an existing constructed CPS spatio-temporal event relies on a system framework and the spatio-temporal event information is not investigated deeply. The method comprises the following steps: abstracting a calculating entity, a physical entity and an interactive entity in the CPS to a first CPS entity with different grain sizes according to the characteristics and the functional demand of the CPS and definition of the CPS entity; establishing a describing form of a first CPS spatio-temporal event corresponding to the first CPS entity, wherein the describing form is represented by a quintuple <Eid, CPS Entity, T, L, R-set>; and determining a first CPS spatio-temporal event statement according to the first CPS spatio-temporal event and a spatio-temporal attribute.
Description
technical field [0001] The invention belongs to the field of information technology, and more specifically relates to a method and device for constructing spatio-temporal events in a cyber-physical fusion system. Background technique [0002] CPS (English: Cyber-Physical-System, Chinese abbreviation: Cyber-Physical-System) is a large-scale complex heterogeneous networked embedded system, which has the characteristics of computing, communication and control integration, and its inherent heterogeneity Structure and complexity bring many challenges to researchers. CPS system can be divided into three parts according to its connotation and function: physical entity, computing entity and interactive entity. Among them, physical entities and computing entities interact deeply in time and space, and these interaction processes are often organized in the form of events. Therefore, studying how to construct CPS spatio-temporal events can not only explore the operating mechanism of t...
