Objective In response to the problems of numerous terminal types, complex operation processes, decentralized system architecture, absent business collaborative synergy, insufficient functional performance, and high upgrading and renovation costs in the communication system of existing urban rail transit lines, an optimized integration scheme for the communication system in existing lines is proposed.

Method First, a theoretical analysis is conducted on the current status and problems of existing communication systems, leading to the determination of an integrated network communication technical architecture based on IP (internet protocol). Second, an integrated communication platform based on microservice architecture and a terminal architecture based on the Windows interface are designed. By utilizing key technologies such as multi-source heterogeneous system adaptation, service decoupling and fusion reconstruction, and multi-node collaborative linkage, various communication subsystems are integrated into a unified data management platform to achieve deep integration of voice, data, and video communications. Finally, the integrated communication platform is established and applied in an actual engineering project at Hangzhou Metro.

Result & Conclusion  The above optimized integration scheme achieves seamless docking with existing communication systems, strengthens the cross-system linkage capability between communication subsystems, realizing the integrated consolidation of operation terminals, system interfaces, and operation processes. This reduces the number of operation terminals by 80%, improving operational efficiency significantly. With lower renovation costs, the proposed scheme meets the higher-level functional requirements of urban rail transit operators, demonstrating higher engineering practicality and promotion value.
