Project Background
Urban tunnel groups are usually managed centrally by municipal authorities, covering traffic tunnels, drainage tunnels, utility tunnels and other types. The traditional O&M model relies on paper work orders and manual inspection, resulting in slow fault response, hard-to-guarantee inspection frequency, and siloed system data that cannot work in concert.
This system builds a unified smart O&M platform for urban tunnel groups, achieving closed-loop management of "sensing — analysis — decision — execution".
System Functions
Real-time monitoring
- Full video surveillance coverage (AI smoke-and-fire recognition, illegal parking detection, pedestrian intrusion detection)
- Environmental parameters (CO/VI smoke concentration, wind speed and pressure, water accumulation level)
- Electromechanical equipment status (lighting, ventilation, drainage pumps, fire protection facilities)
- Structural deformation (settlement, convergence)
O&M management
- Electronic management of equipment ledgers (location, model, maintenance records)
- Automatic fault work-order dispatch (automatically assigned to the responsible crew based on equipment type and location)
- Inspection task scheduling and check-in records
- End-to-end tracking of maintenance work orders
Digital twin cockpit
- Real-time mapping of electromechanical equipment status onto the tunnel's 3D model
- Color-coded equipment status (green = normal / yellow = warning / red = fault)
- Hover to view equipment details
- Emergency scenario simulation (fire ventilation scenarios, flood drainage scenarios)
Key Metrics
- Number of tunnels connected: configured per project scale
- Equipment integration: compatible with 50+ equipment brands (Modbus TCP / OPC UA / HTTP API)
- Warning response time: <30 seconds
- Digital twin frame rate: ≥30 FPS
- System availability: 99.5%
Deployment Options
Supports public cloud or private (on-premises) deployment, with data retained within the owner's domain, meeting government informatization compliance requirements.
