01 · BACKGROUND
Customer Background
Enterprise Type
A cross-sea bridge operating enterprise, responsible for operation management and electromechanical facility maintenance of large cross-sea bridge-tunnel channels, classified as a national major transportation infrastructure operator.
Enterprise Scale: [TBD]
Channel Scale
The channel includes cross-sea bridges, underwater tunnels, artificial islands, and other diverse structures. Distribution rooms, server rooms, and pump houses along the route are widely distributed, with various electromechanical facilities and complex power loads.
Channel Length/Facility Count: [TBD]
Industry Position
National-level transportation infrastructure, must strictly comply with JTG D70/2 Highway Tunnel Design Code and GB 50016 Building Design Fire Protection Standard, with extremely high safety operation requirements.
Compliance Standard: JTG D70/2 / GB 50016
02 · CHALLENGES
Business Challenges
Marine Environment Corrosion Causes High Electrical Hazard Incidence
Cross-sea channels are exposed to high salt spray and high humidity marine environments to long periods, distribution lines and equipment insulation are prone to aging, Leakage and electrical fire hazards are significantly higher than land scenarios, traditional manual inspection Cannot detect them in time.
Scattered Facilities Along Route, High Manual Inspection Cost
Distribution rooms, server rooms, pump houses, and toll stations along the channel are scattered across multiple points on bridge-tunnel artificial islands. Manual inspection is time-consuming with limited coverage, and some areas are difficult to inspect frequently due to traffic control.
Large Tunnel Electromechanical Load, Difficult Temperature Monitoring
Tunnel lighting, ventilation fans, fire pumps, and other high-power equipment operate for long periods. Cable joints and distribution box temperatures are prone to abnormal increases, and without continuous online temperature monitoring, overheating hazards are difficult to warn in advance.
Emergency Response Lacks Real-Time Data Support
During emergencies, the O&M team needs real-time electrical status data to support emergency decisions, but the existing SCADA system does not cover end distribution circuits. Data blind spots affect emergency response efficiency and handling accuracy.

Network Topology
Sensing Layer: ESA Electrical Safety Monitoring Alarm Devices are deployed at corridor main distribution cabinets and primary distribution boxes; ESB Electrical Safety Monitoring Terminals are deployed at secondary distribution boxes and M&E equipment control cabinets; EST Temperature Sensors are attached to cable joints, busbars, breaker contacts and other key hot spots; ESX Electrical Safety Monitoring Devices are deployed at tunnel M&E control boxes, covering lighting, ventilation, fire pump and other circuits.
Network Layer: Each sensing terminal connects via RS485 bus (Modbus-RTU protocol) to a nearby FG Smart Gateway. The FG Gateway uploads via optical fiber private network / 4G cellular network uplink to the corridor operator's internal network. Key nodes support dual-link redundant backup to ensure data transmission reliability.
Platform Layer: Data aggregates to the FEXLINK Cloud Platform (privately deployed), providing web & mobile visualization dashboards, real-time alarms, historical trend analysis, O&M work order dispatch, compliance report auto-generation, multi-role permission management and other functions.
Integration Layer: The cloud platform integrates with the corridor's existing SCADA, BAS, and M&E O&M management systems via standard REST API / Modbus TCP protocols, achieving data sharing and linked alarms, unified into the O&M work order process.
