Abstract:It is tightly coupled between the simulation task and equipment in traditional distributed virtual maintenance training systems, so the system simulation running is inefficient and difficult to expand. In addition, the simulation resource sharing and maintenance cooperation is also a big problem. In order to solve these problems, the infrastructure and realizing framework of cloud simulation were put forward for the application in weapons virtual maintenance training field. The multilayer infrastructure of Run Time Infrastructure (RTI) component was studied. The key techniques were settled, such as federated members excogitation and transport, simulation process monitoring, simulation visualization and distributed storage. The virtual maintenance system was developed based on cloud simulation technologies, which indicated that cloud simulation was feasible and effective.
