Research Of CTCS-3 Train Control Simulation System Testing Method And Subsystem Testing Application

"CTCS-3 train control simulation system" was a semi-physical simulation project conducted by State Key Lab of Rail Communication and Control,based on Beijing-Shanghai high-speed railway,which contained software as well as hardware.This project simulated the functions of the real CTCS-3 train control equipment and was aimed at students of railway signal.This thesis studied the simulation tests on train control simulation system,based on real CTCS-3 equipment tests,so as to acquire efficient and accurate results.This thesis emphasized on several aspects as follows:(1)This thesis firstly analyzed the test specifications and system requirements of each part of the train control simulation system,designed the test configuration and test strategy according to software test technique and extracted the functional points of each module to assist the test on train control simulation system.(2)Then,this thesis designed a series of test cases based on black box method,conducted the tests accordingly,and analyzed the modules where problems exists.(3)Last but not the least,this thesis designed the detailed test procedures on typical modules of train control simulation system,i.e.,the Track Circuit,the Balise,the Temporary Speed Restriction server,Computer Based Interface and used QTP as an auxiliary tool to conduct the balise telegram module.By this means,the test efficiency was greatly improved.Based on test requirement and test cases,the designed functional test demonstrates the integrity of train control simulation system,and assured that this simulation system was able to meet the demand of teaching experiment.The analysis on typical subsystem test requirement and the design of its test procedures,improved the effectiveness of train control simulation system and had a positive significance on improving the train control simulation system.
