An expanding device and method from logic tree to physical tree in fault analysis

Abstract

The invention discloses an extension device and a method from a logic tree to a physical tree in a malfunction analysis, which can realize the exact location to malfunction. The extension device comprises a logic tree management module used for arranging a malfunction detection point and establishing the logic tree which presents an equipment malfunction mode according to the malfunction detection point, a configuration management module used for establishing a configuration database according to the current configuration, a correlation analysis knowledge base which is connected with the logic tree management module and the configuration management module and used for achieving malfunction detection according to an analysis rule, and a physical tree extension module which is connected with the correlation analysis knowledge base and used for determining an edge method according to a node pair in the logic tree. Compared with the prior art, the device and the method of the invention can be smartly and self-adaptively extended from the logic tree to the physical tree, have high efficiency and exact positioning, and can be widely applied to mobile communication equipment malfunction analysis.

Description

technical field [0001] The invention relates to the field of failure analysis of mobile communication equipment, in particular to a device and method for extending logic tree to physical tree in failure analysis. Background technique [0002] In the current failure analysis of mobile communication equipment, it is mainly based on the FMEA (Failure Mode Effect Analysis) method. FMEA is based on the fault tree design in advance, that is, according to the logical design view and data processing flow of the equipment, the fault detection point is designed. In the process of fault location, branches and nodes are expanded according to the predefined fault tree. In some other methods, some adjustments are made to the expansion of the fault tree according to the historical information of the fault. [0003] In complex serialized equipment, the current fault analysis methods are difficult to adapt to the rapid replacement of equipment, and it is even more difficult to adapt to the...
