01 · BACKGROUND
Customer Background
Enterprise Type
A cross-sea bridge operating enterprise, responsible to 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, 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 to long periods, cable joints and distriBution box temperatures are prone to abnormal increases, lacking continuous online temperature monitoring means, overheating hazards are difficult to warn in advance.
Emergency ResponseLackReal-TimeData Support
