Event Information Structural Model Based On Person-object-scene Information Fusion In The Environment Of Internet Of Things

In the recent years, with the Germany "Industry 4.0" being put forward, the reformations of manufacturing industry have become the current hotspot issue. With the help of the continuous popularization and application of the new information technologies such as Internet of Things, big data, cloud calculation and etc within the industry, the manufacturing industry has changed in the micro-levels, and these changes also mark the appearance of intelligent manufacture as a new-type manufacturing mode. Macroscopically, intelligent manufacture has already been able to satisfy the customer's personalized customization demands, and the manufacturing enterprises are not isolated from each other, the manufacturing mode has developed towards the directions of service-oriented resources, coordination-oriented process, alliance-oriented industry and social manufacturing capacity. On the micro level, the manufacturing process has developed towards the directions of real time, automation and intellectualization. The bottom manufacturing processes of intellectual manufacture depend on the cyber physical systems, and the manufacturing processes are digitalized, so that the enterprises could be able to collect and perceive the multi-source information in the manufacturing processes in real time, especially the object information and environment information in the manufacturing processes, in order to form the management situation information fusing "person-object-scene". It could realize the management significance explanation on base of the management responsibility and management demand required by "person" and the real situation represented by "scene ". The management situation fusing "person-object-scene " is the particular situation issue in the management mode of intellectual manufacture. As the fundamental research in the intellectual manufacturing processes, the management situation modeling based on "person-object-scene " information fusion connects the cyber physical systems and management decision levels, it is the base of the information description in the manufacturing processes of intellectual manufacture, and the base of resource information interaction of virtual manufacturing as well, and meanwhile it also the environment on which the autonomous decision of the decision-making unit relays under the multi-level decision modes.The nature of the management situation model based on the "person-object-scene " information fusion is the expression to the events in the management process, and it always produces a large number of significant events in the production and operation processes of the enterprises. Generally speaking, it is the handlers who make the decision response according to the environment in which the event is happening and his business responsibilities and demands, the event decisions make further influences on the management situations in order to provide environment to the appearance of new event to form the event drive process. However, the existing researches are starting from the static information processing, and still lack of effective methods in the understandings and structures of the real-time event information based on the person-object-scene of the cyber physical system in the real-time process.On base of this background, in this article it firstly concludes the domestic and foreign research status of discrete event system, event-driven architecture, summarizes its relevant theories, and provides the concepts of system and status in the system theory, as well as the architecture models of the event-driven architecture. Secondly, it provides the relevant concepts of information in "person-object-scene " as well as the event system architecture based on "person-object-scene" information fusion, proposes the mode structure and mode of information processing of "person-object-scene " information fusion. At last, it carries out the ontologic representation to the scene information and scene knowledge, and takes the steel casting-rolling process as the practical example to carry out the application verification on the proposed "person-object-scene" information fusion model.
