Embodiment Construction

[0033] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0034] First, in this application, the logical view of fault analysis is called a logical tree, and the physical view of fault analysis is called a physical tree. The logic tree is the basis of fault analysis, which is determined in the system design stage, that is, the effective detection points are determined in the design stage. The physical tree is based on the logical tree, combined with the current fault phenomenon, and gradually established in the fault analysis stage.

[0035] Fault analysis is not purely abstract, but the user corresponds to the specific physical equipment during the system maintenance process. In the process of extending from logical tree t...

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...
