Device for diagnosis of breakdowns, assisted by computer, for a system complex technique

摘要

In this device comprising a stage (2) for the preparation of unwinding of the diagnostics, in which is stored a knowledge base comprising a structure model, a model of action and a model of breakdowns, and a stage of execution of diagnosis (1), the model of breakdowns is established from the model of the structure and of the model of action by the fact that this stage provides an object of the base of the model of breakdowns, for each module of the knowledge base, an object of a breakdown, for each zone of action hierarchically superior of the model of action, contingent hierarchically to the object of the base of the model of breakdowns, and an object of a breakdown, for each zone of action subordinated hierarchically in the model of action, and an object of a breakdown, for each zone of action is partially formed by the opening of the point of separation according to a list of priorities. & br / application, in particular, the diagnosis of failures in a motor vehicle.
