Research Of Ctcs-3 Field Test And The Assistant Tool

CTCS-3(China Train Control System Level 3) is the core of protecting high-speed railway traffic safety and improving the transport efficiency. For the purpose of high-speed railway putting to successful operation, the integration scheme, interfaces, the function requirements and the operational requirements of CTCS-3 should be verified in real field test, At present, there is no standardization for the field test in our country. How to carry out field test is a major issue for the CTCS-3.Based on the research of the CTCS-3 structure and the analysis of the requirement of field test, it carries out a detailed description for field test and proposes a field test plan, it presents test framework and test sub-sequences for field test, and covers all the test cases which are applied on field test. The analysis shows two main problems:the searching of test route and the drawing of station yard graph.About the first problem, this paper proposes one improved route searching methods-reverse route searching. It uses the similarity between station yard and binary tree, divides the station yard into different blocks by the switches, establishes the relations between the blocks, builds binary tree model through the blocks, and finally completes routes searching.About the second problem, this paper gives two different ways to solve the problem: based on the AutoCAD source file and based signal data table source file. It gives the advantage and weakness between the two kinds of methods, and selects the first methods according to the demand. This method extracts the relational information to draw the station yard graph. Also route searching can be executed after drawing the station yard graph.In the end, the test sequences generation tool achieves such functions as route setting (automatic and manual) or filling test items or test document output, etc.The methods and the tools have been applied to the systematic commissioning and integration test for Shanghai-Hangzhou high-speed way. It makes great convenience and efficiency for the filed test.
