Acceptance Test Method and System of Urban Rail Transit CBTC System

Abstract

The invention discloses an acceptance test method and a system for a CBTC system of urban rail transit. The method comprises the following steps: S1, according to the technical specification of the CBTC system, extracting the functional characteristics of the system; S2, analyzing the relationship between the functional requirements and the functional feature points of the system, and generating the test requirements specifications of the system; S3, analyzing the relationship between the test cases and the functional characteristics, and generating the use case library of the system functiontest; S4, generating a functional test sequence covering all the test requirements of the CBTC system according to the determined functional characteristics and test cases; 5, measuring that coveragerate of the function test of the CBTC system accord to the system function requirement to the system test requirement and then to the tracking and tracing relationship of the t cases; S6, according tothe attributes of the test case, testing the test case in the laboratory and in the field. The invention provides a scientific basis for acceptance work by adopting an acceptance test mode combininglaboratory test and field pilot test.

Description

technical field [0001] The invention relates to an acceptance test method and system of an urban rail transit CBTC system. Background technique [0002] CBTC system (train automatic control system based on wireless communication) equipment has always been the focus and difficulty of urban rail transit construction. Its system functions, system reliability and security directly affect the operation efficiency and driving safety of urban rail transit. Existing engineering experience shows that a new signal system equipment often has to go through a rather long research and test cycle from research and development to engineering application. From the perspective of the system life cycle, before the system is put into engineering project application, the system must be confirmed through the acceptance test to ensure the quality and safety of the system, so as to improve the confidence in the safety of the system. [0003] At present, the main method of checking and accepting th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the fact that the main means of checking and accepting the CBTC system in the prior art is to rely on the test cases and testing means provided by the system equipment manufacturer, and to conduct simple tests under field line conditions, resulting in a lack of fairness in the acceptance results In order to solve the deficiencies of integrity, completeness and scientificity, an acceptance test method and system for urban rail transit CBTC system are provided
