Software remote fault diagnosis and repair method based on knowledge base

Abstract

The invention provides a software remote fault diagnosis and repair method based on a knowledge base, which comprises the steps of modeling and storing the operation conditions, dependence relationship, fault performance characteristics and repair strategy of each software component in a diagnosed software system to form a fault diagnosis and repair knowledge base; storing the knowledge base on a service terminal of the diagnosed software system; installing a client-side agent in the diagnosed software system, installing a server-side program on the service terminal, acquiring the diagnosis information of the diagnosed software system in real time by use of the client-side agent, and transferring the diagnosis information to the server-side program through the network; generating a decision command by the server-side program according to the acquired diagnosis information and the knowledge base, and transferring the decision command to the client-side agent through the network; executing the decision command by the client-side agent to realize the diagnosis and repair of the software fault. By adopting the method provided by the invention, intelligent diagnosis and repair of software faults are realized, and the efficiency and automation degree of software fault diagnosis and repair are improved.

Description

technical field [0001] The invention relates to the field of software fault diagnosis and repair, in particular to a software remote fault diagnosis and repair method based on a knowledge base. Background technique [0002] In the industrial process, the meaning of hardware fault diagnosis is to determine the cause, location and severity of system abnormality or failure based on the measured value of a specific sensor. The function of the hardware fault diagnosis expert system is to automatically complete the diagnosis of system abnormality or failure according to the measurement information and computerized diagnosis knowledge. Software fault diagnosis is still a relatively new thing, and software faults are quite different from hardware faults in terms of fault mechanism, which will inevitably lead to certain differences in the diagnostic methods of the two. The mathematical model of the software system is discrete, there is no physical reason for the formation of faults,...

AI Technical Summary

Problems solved by technology

Software faults are difficult to locate, and the failure phenomenon often does not appear in the failed components. Hardware faults are easier to locate, and the physical parameters of the failed components often change significantly.

If a software is found to have a certain failure, then all software of that version may have the failure
