Decision-making method and system for fault mode and influence analysis and storage medium

Abstract

The invention provides a decision-making method and system for fault mode and influence analysis and a storage medium. The decision-making method comprises the steps of obtaining device state data ofeach monitoring point of a target device state; carrying out template matching on the target data stream template and a normal template; when the template matching degree of the target data flow template and a normal template is smaller than a first standard threshold value, determining that the target data flow template is a fault data flow; carrying out template matching on the target data flowtemplate and a fault data flow template, wherein the fault data flow template is a data flow template when equipment has a fault; when the template matching degree of the target data flow template anda fault data flow template is greater than or equal to a second standard threshold, determining that the target data flow template corresponds to a registered fault, and outputting a decision corresponding to the target data flow template; otherwise, determining that the target data flow template corresponds to a new fault. The method can adapt to the flexibility and variability of hardware forms, and can accurately judge faults and give decisions.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a decision-making method, system and storage medium for failure mode and impact analysis. Background technique [0002] At present, customers in the 3C industry have urgent and large demand for computer integrated management of automation equipment. The terminal server business layer of computer integrated management of automation equipment uses EIS (Executive Information Systems) as the management and control carrier of line body operation data, and performs "line body level control" of data on the lower layer data source (machine and line body composition). (Line Control, LC)". In the management and control of equipment status, LC emphasizes results and alarm calls, lacks analysis and decision-making on the cause of failure, and has little application value for equipment manufacturers themselves. [0003] In the communication industry, Datacom network man...

AI Technical Summary

Problems solved by technology

[0004] However, in the 3C industry, the implementation of equipment is mostly customized automation solutions, and the hardware working method is dynamic, involving more disciplines such as electromagnetism, mechanics, dynamics, optics, etc., and the hardware components of the equipment are diverse. The working mode of the server is static, and the hardware is mainly composed of circuit board components, so the hardware information of the customized automation equipment cannot be described and monitored by the fixed electronic model and thermal model like the server.

If the defect model of components is counted according to the electronic model of the server, the data source cannot be converged; and because it is a customized solution, the demand may change at any time, and the iteration speed of product form and function requirements is much higher than that of communication industry, so the hardware design rules cannot be converged
