Optimal Design of DCS Subsystem Monitoring for Urban Rail Transit Signal System Under Cross-line Network

It will be an important way to improve the transportation efficiency of the urban rail transit system in the future to realize cross-line networking on the existing line. Cross-line operation will bring great challenges to the data communication subsystem of signal system. In order to ensure its reliable and stable operation, it is necessary to integrate the scattered monitoring functions and form a complete monitoring system. Combined with the current urban rail transit network operation management, this paper designs the data communication subsystem network monitoring architecture, and carries out the cross-line simulation test and monitoring of important parameters on city cross-line. The results show that it is feasible and necessary to construct the cross-line data communication system monitoring network system.
