01 · BACKGROUND
Customer Background
Enterprise Type
A highway operation enterprise, responsible for highway operation management, M&E facility maintenance and toll services, a national key transportation infrastructure operator.
Enterprise Scale: subject to site survey
Road Section Scale
Highways contain main lines, tunnels, bridges, service areas, toll stations and other multi-facility infrastructure. Along-route distribution rooms, equipment rooms, and monitoring centers are widely distributed. M&E facility types are diverse, and power loads are complex.
Road section range/facilities count: Online inspection
Industry Position
National key transportation infrastructure facilities, need strict compliance with JTG D70/2 "Highway Tunnel Design Specifications" and GB 50016 "Building Design Fire Protection Specifications" and other standards. Safe operation requirements are very high.
Compliance Standard: JTG D70/2 / GB 50016
02 · CHALLENGES
Business Challenges
Along-Route Facilities are Scattered, Manual Inspection Cost is High
Highway along-route distribution rooms, toll stations, service areas, and tunnel substations are scattered across hundreds of kilometers of road sections. Manual inspection is time-consuming, coverage is limited, and some regions affected by traffic control are hard to inspect at high frequency.
Tunnel M&E Load is Large, Temperature Monitoring is Hard
Tunnel lighting, ventilation machines, fire pumps and other large power equipment operate for long periods. Cable joints and distribution box temperatures easily rise abnormally. Lacking continuous online temperature monitoring means, overheating hazards are hard to warn about early.
Outdoor Environment Causes Electrical Equipment Aging to Accelerate
Highway distribution facilities are mostly in outdoor environments, long-term withstanding high temperature, high humidity, lightning strikes and other harsh conditions. Electrical equipment insulation easily ages, and leakage and electrical fire hazards are significantly higher than indoor scenarios.
Emergency Response Lacks Real-Time Data Support
Under emergencies, O&M teams need real-time electrical status data to support emergency decisions, but existing SCADA systems do not cover end distribution circuits. Data blind spots affect emergency response efficiency and handling accuracy.

Network Topology
Sensing Layer: ESA Multi-Parameter Smart Meter deployed at along-route distribution room main distribution cabinets and tunnel substations, ESB Three-Phase Imbalance Monitor deployed at toll station and service area secondary distribution boxes and M&E equipment control cabinets, EST Multi-Channel Temperature Controller attached to tunnel cable joints/busbars/breaker contacts and other key hot spots, ESX Intelligent Edge Computing Gateway deployed at tunnel M&E control boxes, covering lighting, ventilation, fire pumps and other circuits.
Network Layer: Each sensing terminal connects via RS485 bus (Modbus-RTU protocol) to nearby ESX Intelligent Edge Computing Gateway. ESX Gateway uploads via highway power grid optical fiber/4G cellular network uplink to road section monitoring center grid network. Key nodes support dual-link redundant backup to ensure data transmission reliability.
Platform Layer: Data aggregates to FEXLINK Cloud Platform (private deployment), providing web & mobile visualization dashboard, real-time alarm, history trend analysis, O&M work order dispatch, compliance report auto generation, multi-role permission management and other functions.
Integration Layer: Cloud platform through standard REST API / Modbus TCP protocol, integrates with highway existing SCADA, monitoring center, M&E O&M management system, achieving data sharing and linked alarms, unified into O&M work order process.
