摘要
The high-speed railway signaling system is the core equipment for the safe and reliable operation of high-speed railway. The realization of intelligent operation and maintenance of high-speed railway signaling systems is the fundamental guarantee to reduce the operation risk of high-speed railway. However, the research on the operation and maintenance of high-speed railway signaling systems is still in early stage. Most of existing works were concerned about the systems in device level or the most basic level and few works focused on the whole system. There is a tremendous need to set up theoretical model of global structure on the whole. In this paper, we first define a concept of interrelated signaling system, propose a decentralized dynamic evaluation function and incorporate dynamic scheduling into the operation and maintenance system, based on which we construct a hierarchical structure model for high-speed railway signaling systems. After that, we give some research methods of dynamic quantitative evaluation, dynamic risk early warning and fault diagnosis for the decision-making layer and interrelated-signaling layer of hierarchical structure model, and finally discuss the challenges in these aspects.
