面向维修训练的故障建模、仿真与评估

Fault Modeling, Simulation and Evaluation for Maintenance Training

面向维修训练领域,通过研究系统故障产生机理,运用面向对象方法建立一种基于故障传播有向图的系统故障模型,从工程应用角度阐述了其构建规则。基于该模型实现了维修训练仿真系统,介绍了有向图仿真运行类结构和维修对象测量数据的生成。在此基础上,文章提出一种基于标准故障诊断路径的评估方法,根据测量点与标准路径的相关性实现了维修训练评估。

Oriented for maintenance training domain and under the research of the system fault generating mechanism, this paper uses obJect-oriented method to set up a system fault model based on fault spreading directed graph. In the engineering perspective, its constructing rules is introduced. And the maintenance simulation system is realized, indicating the runtime structure of the directed graph and the generation of the measuring data during the simulation. On all above, an evaluation method is mentioned according to the relativity between the measuring point and the standard fault diagnosis routes.
