The Collaborative Virtual Maintenance System Based on Spnss

To realize multiuser collaborative virtual maintenance training of large complex equipment and solve the collaborative work problems such as parallel and competition for resources, a method based on synthesis of Petri nets sharing a kind of subnet for modeling collaborative maintenance process was put forward and the key technologies such as hierarchical modeling of the simulation task, virtual prototype modeling, maintenance process modeling, visual simulation and the program driver were realized. Through the analysis of the functional requirements of the system and based on the human- machine interaction of the virtual reality development EON Studio function node and the integrated communication function between EonX and Visual Studio, a system framework is presented for multiuser collaborative virtual maintenance simulation training platform and the multiuser collaborative virtual maintenance simulation training system was developed. Take the main power device of a type of ship gear box fault bearing maintenance conversion as an example, we illustrate the working process of the collaborative virtual maintenance system and verify the key technologies of the system.
