Fault diagnosis method and system based on interface control document

Abstract

The invention provides a fault diagnosis method and system based on the interface control document (ICD). In the system of the invention, an ICD database is used to store benchmark data; a diagnosis script library is used to store a plurality of diagnosis scripts and a plurality of functions called by the diagnosis scripts; and an ICD analysis module analyzes the data packet of a diagnosis object to obtain the data to be diagnosed and the data name. The fault diagnosis method is as follows: according to the data name and data route of the diagnosis object, the data definition of the benchmark data with the same data name and data route is read from the ICD database; the data definition is utilized to convert the data to be diagnosed to the parameter detection result of the data to be diagnosed; and a reasoning module uses the diagnosis scripts and the functions to perform fault diagnosis to the parameter detection result of the data to be diagnosed and outputs a fault diagnosis result. By adopting the method and system of the invention, when fault diagnosis is performed, the ICD is utilized for storage and analysis, thus reducing the computation workload, increasing the universality and the flexibility and having the capability of expressing all kinds of knowledge conveniently and effectively.

Description

Technical field [0001] The present invention relates to control technology, in particular to a fault diagnosis method and system based on an interface control document (ICD). Background technique [0002] Fault diagnosis refers to the quantitative identification of the real-time technical status of the equipment and its components through the processing and analysis of the status information of the measuring equipment in operation or under relatively static conditions, combined with the historical conditions of the equipment, and the prediction of related abnormalities, faults and malfunctions. The technology to predict its future technical status and determine the necessary countermeasures; its purpose is to diagnose, prevent or eliminate various abnormal operating conditions or fault conditions of the system in a timely and correct manner, so as to provide necessary guidance for the operation of the equipment. Improve the reliability, safety and effectiveness of system operatio...
