Research On Simulation Technology For Emergency Rescue Drill Of Petrochemical Factory By Virtual Reality

To ensure the production safety is a vital task for the petrochemical enterprise. Recently, most of petrochemical enterprises have attached great importance to the safety education for their workers, but they always use the traditional style of education, such as books, examinations via paper. Although such safety training modes can help employees learn much knowledge of emergency rescue, workers are not able to understand the real situation of the disaster site or to experience emergency rescue process.With the rapid development of computer graphics and geographic information system technology, a virtual reality for the petrochemical plant emergency rescue drill platform is designed and implemented. This platform makes use of real three-dimensional virtual reality technology to simulate petrochemical park layout and various elements of the rescue and emergency rescue process. The geographic information system technology is used to synchronize the data of virtual reality world and to analysis the optimal route of rescue and the movement situation of people.The research of virtual reality part in the simulation platform involves special equipment, production disasters, people and other elements of the rescue. The algorithm of optimize rendering, physics simulation, dynamic texture technology are researched in this thesis. The platform uses OGRE virtual reality engine, BULLET physics engine and other technologies to implement. In the part of Geographic Information System, the approach of interaction between virtual reality and geography information system is designed. The algorithms of selecting the optimal route according to the cost of the road and calculating the situation of people are proposed. This part is implemented by the MAPWINGIS and POSTGRES database. In addition, the relevant data tools are designed and implemented.The key techniques of emergency rescue drills and the platform designed in this thesis have been used in an emergency rescue system of a large petrochemical enterprise. According to the result of application, these techniques can successfully simulate emergency rescue procedures and the petrochemical park layout. This platform can be used by workers of chemical enterprise, so that it is suitable for emergency rescue education and training in the petrochemical factory.
