Future prospects on the intelligent monitoring technologies for railway signalling systems in China

This paper makes a survey on the current development, underlying issues, and the future prospects associated with China railway signalling monitoring technologies. To overcome the problems involved such as interconnection, data sharing and intelligent analysis, an integrated scheme of the intelligent monitoring and maintenance system for railway signalling systems is further presented. In this scheme, all kinds of monitoring data are centralized to conjointly and intelligently analyze the status of signalling devices. Moreover, interacting with the maintenance management system, the integrated scheme will have the functions of monitoring, diagnoses, intelligent maintain and management, which will greatly improve the usability of railway signal. Finally, some principles and precautions are pointed out in the future construction of the proposed scheme.
