Abstract
High-speed train tracing and an approach-alarming system is independent of the
existing train control system, which uses the Global Navigation Satellite System
and Integrated Location System for positioning to ensure the safety of trains and
to prevent an accident of train collision caused by failure of the train control
system. The system provides autonomous train tracing and positioning services,
and sends different levels of safety alarm according to the distance between the
adjacent trains. Based on the performance testing conducted on HanYi Railway
of China (from Wuhan to YiChang), the requirements, architecture and working
principle of the system, as well as the purpose, conditions, scene setting and
process of the testing are expounded in this paper. According to three function
indexes including the judgment of the train’s position, analysis of the train’s
running mode and its transforming, plus the state of alarming and its
transforming, the test data have been analyzed and discussed. At the end, the
evaluation and conclusion of the testing are provided with a further discussion on
the deficiency of and remedial measures for the system.
Keywords: high-speed train, tracing and approach-alarming, GPS, DGPS.
