摘要
针对虚拟维修培训中可能存在不同培训任务的问题,建立了基于Petri网的培训任务规划模型,定义了Petri网广义变迁的扩展属性,提出了利用Petri子网来控制具体任务仿真的基本步骤;通过对变迁相关属性的合理编码,解决了从总体Petri网中提取Petri子网的问题,从而实现了Petri网对不同培训任务的可规划性。最后将结论应用于某齿轮减速箱的拆卸任务规划中,证明任务规划方法的有效性。
Aimed to resolve the problem of different training goal during the virtual maintenance training, a model titled training task-planned based on Petri-Net is presented, and the extended properties of broad Transition of Petri-Net is defined. The basic steps of a concrete simulation task controlled by the Petri-Net are suggested ; the sub-net can be taken from total Petri-Net by reading the code of transition properties, and the problem that the Petri-Net can be planned according to different training task is resolved thereby. Finally, the conclusion is drawn and applied in the disassembly simulation of a gear-box, with the result supporting the conclusion.
