specific Embodiment approach

[0048] (1) According to the requirements of the information system in terms of production, management, maintenance, and upgrades, collect the operating parameters and status parameters of the measured object shown in the monitoring layer ①, including operating system status, online and offline, operating conditions, and hidden system bugs , upgrade and maintenance history records and related network equipment, hardware equipment status parameters, etc.

[0049] (2) Since various information systems have different application requirements and characteristics, the condition-based maintenance of information systems is centered on databases, rule bases, algorithms, models, strategies, and expert knowledge. Based on the monitored information in step (1), combined with Necessary rule requirements, fault models, and disposal methods form the original data such as the rule base and maintenance base shown in the data layer ③.

[0050] On the basis of algorithms and models, standardize ...

Abstract

The invention discloses an auxiliary decision-making method for the equipment state maintenance of information systems. The auxiliary decision-making method comprises the following steps: S1, establishing an auxiliary decision-making platform for the equipment state maintenance of an information system, and acquiring state parameters and operating parameters, which are relevant to state maintenance; S2, establishing a two-dimensional relational model of system evaluation indexes, and setting a maintenance timing sequence and maintenance grades; S3, establishing a two-dimensional relational model of time and failure omens, and setting a forewarning threshold and an alarm threshold in the model; S4, obtaining a historical change curve, comparing the historical change curve with the current parameters of the information system so as to judge the state of the current information system, and bringing the judged result into the step S2 so as to obtain a maintenance conclusion. The auxiliary decision-making method disclosed by the invention is used for diagnosing the states of the systems. According to the invention, the system state maintenance aid is realized through rules, models, algorithms and reasoning. The implementation of the method is help to improve the system maintenance level, improve the system availability, reduce the production cost, and improve the economic profits of enterprises.

Description

technical field [0001] The invention relates to the field of equipment condition maintenance, in particular to an information system equipment condition maintenance auxiliary decision-making method. Background technique [0002] Computer and network technology have accelerated the process of informatization. Electric power companies have built various business systems and put them into use in large quantities. While the support for enterprise business systems has been continuously improved and the main business has been greatly integrated, the scale of the system has expanded rapidly. A lot of investment. [0003] The importance of the business system of the power management unit is self-evident. The system outage and data destruction caused by failures have caused great economic losses and reputational impacts on the company. The application of new systems and new technologies increases the failure rate of the system. Enterprises pay great attention to how to improve syst...
