AN INNOVATIVE PLANT INFORMATION SUPERVISORY SYSTEM: THE APPLICATION OF 3D INTERACTION, FIELDBUS AND INTERNET TECHNOLOGIES IN INDUSTRIAL PROCESS FIELD

摘要

In this paper, a three-level plant information supervisory system is constructed. On this basis, the main part, an innovative human computer interface based on virtual reality technology is presented. By this interface, devices conditions and data in industry supervisory field can be reflected by the method of 3D visualization in real time. And 3D interactions such as navigation, pushing and grasping virtual objects etc. can also be realized by common interaction tools in the virtual environment. Furthermore, this 3D interfaces can be embedded into most industrial automation softwares and published through Web pages. Thus, users can deal with their supervisory tasks more easily and effectively.
