Intelligent Monitoring Technologies for Railway Signaling Systems in China

The state of the art in the monitoring technologies for railway signaling systems in China was introduced. By analyzing the drawbacks of these technologies in interconnection, data sharing, intelligent analysis and prediction, as well as their development trend and maintenance requirement, a scheme of an integrated intelligent monitoring and maintenance system for railway signaling systems was presented. The system structure, functionality and key technologies involved such as shared data selection, data integration mechanism, intelligent analysis and interface specifications were also elaborated, which provide the feasible alternatives for the condition-based maintenance of signaling equipments. Moreover, the layered implementation principle based on current monitoring situation, and the security isolation between the monitoring system and signaling systems were discussed.
