Foreword    Preface
With the continuous expansion of urban rail transit networks, data silos, business fragmentation, and manpower investment have brought greater challenges to communication operation and maintenance work. To effectively address these issues, Far East Communications has launched the Urban Rail Communication Intelligent Operation and Maintenance Platform.

The Urban Rail Communication Intelligent Operation and Maintenance Platform (hereinafter referred to as the Intelligent Operation and Maintenance Platform) integrates data from various subsystems, mines the rules of alarm, performance, and log data, and continuously improves the ability to analyze operation and maintenance data, intelligently assists in fault diagnosis, helps operation and maintenance personnel quickly discover imperceptible faults and hidden dangers, transforms passive operation and maintenance into proactive operation and maintenance, saves manpower costs, and improves overall efficiency.

Holistic Data Perception
Operation and maintenance management,   Unified and convenient

 
The intelligent operation and maintenance platform adapts to various network communication protocols, establishes unified data standards and management models, and manages massive alarms, performance, and logs from various subsystems of urban rail communications. Data is centrally stored and managed, Utilizing the computing and processing capabilities of the big data platform, Conduct centralized governance and in-depth mining, Breaking the status quo of decentralized management and data fragmentation in various systems, promoting the transformation and upgrading of operation and maintenance management through data integration.

Full-Scenario Digital Twin
Device status, at a glance

The intelligent operation and maintenance platform comprehensively uses digital twin, big data visualization, and BIM (Building Information Modeling) rendering technologies to reproduce the machine room, cabinets, and equipment in a three-dimensional scene, and at the same time, combined with the communication system network topology diagram, from Multi-dimensional clear display of system and equipment status, Can intuitively locate equipment failures and improve user experience.

Full-Process Closed-Loop Control
Fault handling, accurate and efficient
 

The intelligent operation and maintenance platform manages faults throughout their lifecycle, establishing an alarm-fault-work order-fault knowledge base-alarm maintenance suggestion Full-process control of faults, Realizing closed-loop operation and maintenance business, and Through data archiving for continuous governance, Reduce cumbersome work caused by scattered processes, and support multi-terminal collaboration of PC + mobile APP, making operations more flexible.

Full-Process Intelligent Monitoring
Quick prediction, improved decision-making

The intelligent operation and maintenance platform uses big data technology and machine learning to monitor and analyze equipment operation data in real time, which can Achieve "pre-warning" of anomalies; It can also mine the causal relationship and root cause location between a large number of alarms based on the adversarial network model, making Fault location efficiency increased by 30%, achieving "rapid diagnosis" of faults. In addition, the platform utilizes a health assessment system based on expert rules, Realize equipment health "status prediction," Promoting the evolution of operation and maintenance work from planned maintenance to condition-based maintenance, solving problems such as insufficient or excessive maintenance.

Summary
Currently, the urban rail communication intelligent operation and maintenance platform has been applied to lines in six cities. In the future, Far East Communications will continue to leverage its advantages in communication integration and product R&D, striving to build a digital and intelligent integrated operation and maintenance solution for urban rail communication system operation and maintenance business, and empower urban rail communication intelligent operation and maintenance business.
