In order to ensure that the urban rail transit system can operate reliably, safely and efficiently, and effectively transmit voice, data, image and other information related to operation, maintenance and management, it is necessary to establish a reliable, easy to expand, independent communication network. The communication network system of rail transit mainly includes transmission subsystem, official telephone subsystem, dedicated telephone subsystem, wireless subsystem (train scheduling, public security, fire protection), broadcasting subsystem, television monitoring subsystem, clock subsystem, power supply and grounding subsystem.

As a long-term service provider for optical communication network cabling system solutions, Shengwei has a rich product line and comprehensive solutions, providing a variety of highly reliable, industrial grade, and intelligent overall communication solutions for the entire complex communication system of rail transit. It also provides digital communication systems based on fiber optic transmission, access based on industrial switches and commercial switches Convergence and core communication solutions enable efficient interconnection and interoperability among line control centers, stations, depots, and parking lots, ensuring the accuracy, timeliness, and confidentiality of signals during transmission.

Ø High equipment reliability, low failure rate, all industrial grade products, with excellent industrial environmental adaptability;

Ø Network self-healing and flexible expansion. Supports ring network protection, has strong network flexibility and scalability, and has interconnectivity;

Ø High network effectiveness ensures important tasks. Classify different services according to their urgency and importance to ensure reliable transmission of important services;

Ø High network security ensures the confidentiality of information. Through a physically isolated private network communication system and special shielding materials, ensure that information is not leaked, and is not disturbed or attacked by external signals.

Ø Intelligent operation and maintenance management, unified network management.
