Abstract

The invention relates to a dynamic function test method of a high-speed train operation control system, which belongs to the technical field of high-speed train operation control systems. The method comprises the following steps of: configuring a dynamic test model of a tested high-speed train operation control system based on a parameterization automaton model according to a high-speed train operation control system functional specification; and performing a dynamic test process on the high-speed train operation control system according to the model. In the dynamic test method, a cyclic process consisting of four steps, namely 'generating a test sequence of transfer to be tested', 'executing the test sequence', 'analyzing a test result' and 'updating a dynamic test model parameter' is performed. By the method, the generation of a fixed test sequence set before the high-speed train operation control system is tested is avoided, and the problems of low test coverage rate and low test result accuracy of the conventional static test method as well as high generation cost and high execution cost of a test sequence in the conventional dynamic test method are solved.

Description

technical field [0001] The invention relates to a dynamic test method for the function of a high-speed train operation control system, belonging to the technical field of high-speed train operation control systems. Background technique [0002] The main purpose of the high-speed train operation control system function test is to verify whether the tested high-speed train operation control system conforms to the system function specification. The traditional functional testing of high-speed train operation control systems is mainly based on static testing methods. During testing, problems such as low test coverage and low accuracy of test results have been encountered. Aiming at the problems of static testing methods, some scholars in the field of protocol conformance testing The dynamic test method was first proposed. The dynamic test method generates a larger set of test sequences to be selected before the test is executed. During the test execution, the next test sequence ...
