Development of Desktop Virtual Maintenance Training System with Dynamically Configured Scenarios

Abstract

This paper represents an engineering method to develop a desktop-based interactive virtual maintenance training system, which could configure scenarios dynamically. The interactions of maintenance training scenarios are constructed by hierarchical Petri net. The maintenance knowledge and procedures of assembly/disassembly in virtual environment are presented by using high level Petri net. Each maintenance task is decomposed into a set of sequential basic action element done through left/right hand or both hands. The Petri net presentation of coordination and execution of each task helps to configure scenarios dynamically. This method is conducive to the interactive representation of task and action scenarios in the virtual maintenance training system.
