A method and system for automatic interpretation of associated parameters based on rule configuration analysis

Abstract

The invention discloses a method for automatically interpreting associated parameters based on rule configuration analysis, including: using a definable grammar to construct an interpreting rule of the parameter to be judged in the form of a character string; updating and improving the feature extraction method involved in the interpreting rule in the feature database ; Load the interpretation rules of the parameters to be judged, and perform semantic analysis on the interpretation rules in combination with the feature library; load the parameter data associated with the interpretation rules, and use the interpretation rules after the semantic analysis to interpret the parameter data. The technical solution provided by the present invention overcomes the shortcomings of low efficiency of manual parameter interpretation and slow evidence collection, and is applicable to the occasions of fast and accurate interpretation of a large number of parameters, especially for the interpretation of complex associated parameters, in the field of industrial automation testing and intelligent fault diagnosis It has a good application prospect. At the same time, the present invention also provides a system for automatically interpreting associated parameters based on rule configuration analysis, which has the above beneficial effects.

Description

technical field [0001] The invention relates to the field of data processing applications, in particular to a method and system for automatically interpreting associated parameters based on rule configuration analysis. Background technique [0002] With the rapid development of fieldbus technology and modern sensor technology, more and more parameters can be detected in industrial control process. Most of these parameters are time series data, and they are highly correlated. The upper and lower limits of parameters and their time series characteristics are often closely related to the working status of the system. Therefore, how to interpret and analyze these parameters is very important for evaluating whether the system works normally. [0003] At present, the interpretation of these parameters is mainly completed by manual interpretation by experts' naked eyes, which is time-consuming and laborious, and the interpretation efficiency is low. For occasions where a large nu...

Problems solved by technology

For an interpretation rule, this invention only supports a single feature, and cannot adapt to the logical combination of multiple features, and does not consider the existence of associated features in the rule

Therefore, the method in this invention cannot be applied to complex rule situations such as multiple association parameter combinations and time series association.

[0005] The method described in "Design of Automatic Interpretation System for Space Camera Simulation Test Data" (Computer Measurement and Control, 2010, Volume 18, No. 6) is used in the space camera ground simulation test system. The three types are implemented separately, and the interpretation rules only support the logical "and" combination form. The interpretation algorithm module needs to be adaptively modified as the interpretation rules change, and it is impossible to use an intelligent algorithm to analyze the rules uniformly.
