Abstract

Abstract:

In order to optimize the safety test of signal equipment in the process of integration testing commissioning, the whole process of integration testing commissioning for the signal system was analyzed, and the improvement of the test plan preparation method was proposed. For two typical problems of signal equipment involving driving safety, closed-loop measures were taken to find the cause, formulate rectification plans, on-site rectification, re-testing of real vehicles, and formulate driving management measures. The results show that using planning software can avoid the problem of sequence omission or repetition that is easy to occur in traditional manual planning methods. Through the study of typical problems, it is proposed that special investigation and rectification should be carried out on the whole road to solve the underlying logic problem of equipment. The design source problem can be solved by formulating relevant driving management measures.

Key words: high-speed railway, signal system, integration testing commissioning, driving safety, test plan
