Method for monitoring failure mode of digital communication module

Abstract

The invention provides a method for monitoring the failure mode of a digital communication module. The method is high in monitoring efficiency, high in analysis accuracy and good in output intuition. The method comprises the following steps: searching information needed by failure mode and monitoring mode analysis in a digital communication module topological graph, and generating a topological graph about failure mode and monitoring implementation of an analyzed digital communication module; analyzing a failure mode of a monitoring digital communication module based on topological graph search, establishing a mapping relation between an analyzed module graph and failure monitoring, generating an inherent failure mode of the analyzed module, and carrying out joint judgment reasoning according to an input/output relation and a hinge relation to generate an association failure mode of the analyzed module; and on the basis of the constructed topological graph, outputting a graphical failure mode and monitoring implementation analysis conclusion file in combination with inherent and associated categories of the failure mode and a monitoring mode with reasonable association, and realizing automatic identification of the failure mode of the monitoring digital communication module.

Description

technical field [0001] The invention relates to a method for monitoring failure modes of digital communication modules, which can also be extended to the method for monitoring failure modes of electronic modules in a wide range of electronic systems. Background technique [0002] Failure Mode and Effects Analysis is "Potential Failure Mode and Effects Analysis", or FMEA for short. FMEA is to analyze the subsystems and parts that make up the product, and each process that makes up the process one by one in the product design stage and process design stage, find out all potential failure modes, and analyze their possible consequences, so as to take necessary measures in advance. A systematic activity of measures to improve the quality and reliability of a product. FMEA starts before product design and manufacturing process development activities, and guides the implementation throughout the entire product cycle. It is an inductive analysis method that analyzes all possible f...

Problems solved by technology

The artificial dependence and experience dependence of this method process make the automation degree of the method process low, resulting in low efficiency. When facing the complex digital communication modules in the current large-scale electronic system, it is difficult to quickly and efficiently meet the testability. Design and optimization requirements, this is the key to focus on this issue

[0006] Second, the specialization level of the method object is low

In the analysis of monitoring the failure modes of digital communication modules, circuit designers do not understand the professional knowledge of failure mode analysis and are not familiar with the standards of failure mode analysis, so they need the support of six-sex personnel; The circuit professional knowledge foundation of the special function module of the electronic system is poor, and the monitoring mode of the module can realize the situation analysis. The cognitive ability is insufficient, and it is difficult to meet the professional analysis needs

As a result, the professional level of the analysis of the failure mode of the monitoring digital communication module is insufficient, resulting in the accuracy of the result of monitoring the failure mode of the digital communication module is not high, it is impossible to correctly express the actual possible failure mode of the analyzed module, and it is impossible to correctly determine each The reasonable monitoring mode corresponding to the failure mode is also the improvement of the present invention

[0007]Third, the usability of method output is poor

In the process of monitoring the failure mode of digital communication modules, it is often necessary to generate the analysis results of the monitoring failure mode. It is difficult to perform audit verification and application intuitively and quickly in the traditional written form, and the problem of poor intuitive output is also the focus of the present invention. focus on solving
