基于诊断行为的协同诊断可视化架构设计

Design of collaborative diagnosis visualization architecture based on diagnostic behavior

为解决协同诊断建模技术上的动态可视化弱、协同组织难度大等问题,引入可视化技术,提出一种"可视化诊断行为"的诊断方法,在此基础上完成基于诊断行为的协同诊断可视化平台架构设计。根据协同诊断系统的诊断过程特点及实时显示需要,抽象出与"诊断行为"方法相关的主要模型元素:诊断对象、诊断人员、诊断设备和诊断方法;在此基础上,进行相应的可视化诊断模型元素的设计及可视化系统相应功能模块定义。通过某民用航空发动机涡轮转子工作失效的实例,验证了该平台的可行性和正确性。

Traditional techniques of the collaborative diagnosis modeling usually lead to poor dynamic visualization and difficulties in collaborative organization .To solve these problems ,by introducing the visualization technique and proposing a diagnostic method for the visual diagnosis behavior ,a visualization platform for the collaborative diagnosis was established based on diag-nostic behaviors .Firstly according to the diagnostic process characteristics and real-time display needs of the collaborative diagno-sis system ,the main model elements of the diagnostic method for diagnosis behaviors were abstracted including diagnostic ob-jects ,staffs ,equipments and methods .Moreover ,functional modules were defined for the visualization system of collaborative diagnosis and the corresponding model elements were designed for the visualization diagnosis .Finally the visualization platform for the collaborative diagnosis is proved to be reliable and correct through the fail diagnosis of a civil aero-engine turbine rotor .
