Virtual Simulation of Petrochemical Direct Operation Based on Self-Build Scenes

To covercome the deficiencies of traditional training method based on text and image, a virtual simulation method of petrochemical direct operation is proposed based on self-built scenes by means of virtual reality and simulation, 3D visualization, Internet technology and other advanced technology. According to the characteristics of direct operation such as strong systematicness, complex scenes, high risk and multi-role cooperation, this paper presents a new 3D modeling method based on large scale topographical map and chemical process to model the global and detailed information of petrochemical plants. Distributed interactive simulation technique is adopted for the communication and interaction between different trainees. We use event-based approach to training (EBAT) method and analyze elements of direction operation and logical relationship between different tasks to construct self-built scenes and self-edited courses, so simulation training courses can be expanded indefinitely. The experimental results show the validity of the proposed method.
