An Expert System Approach for Analyzing and Evaluating the Testing Results of CTCS-3 On-board Equipment

摘要

The on-board equipment is an important part of CTCS-3 train control system. In order to verify whether the on-board equipment complies with CTCS-3 system requirements specification, it is necessary to carry out functional testing in laboratory, in which a lot of professional expertise is needed, especially in the analysis and evaluation of the testing results. Therefore, it makes sense to carry out the research on the method for analyzing and evaluating of testing results based on expert system. By establishing a rule base based on production rule representation for rule inference and comparing the rule data with the testing data gathered from various source such as DMI and data recorder, the analysis and evaluation method can be realized. Several key issues such as rule representation, testing data extraction and comparison strategy are addressed in this paper.
