Metro Station BMS Integration

Il problema

Station ventilation, lighting, lifts, escalators and pumps come from different packages, and the station control room has no single view during peak hours or incidents.

Panoramica della soluzione

MILESGO gateways collect data from air handling units (AHU), lighting control panels, lift controllers, escalator controllers, pump controllers and starters, fire alarm panels (read-only) over Modbus TCP / Modbus RTU / BACnet/IP / S7, and deliver it to the BMS, SCADA, the operations / command centre as BACnet/IP / OPC UA / IEC 60870-5-104. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

air handling units (AHU)
lighting control panels
lift controllers
escalator controllers
pump controllers and starters
fire alarm panels (read-only)

Protocol path

Modbus TCP / Modbus RTU / BACnet/IP / S7 → BACnet/IP / OPC UA / IEC 60870-5-104

Implementation checklist for the project manager

Fire and life-safety systems are monitored read-only; control stays with the certified fire system.
Freeze the point list and protocol mapping with the client before ordering hardware.
Agree BACnet device instances, network numbers and BBMD with the BMS contractor to avoid conflicts.
Keep OT networks segregated and use VPN for remote access instead of opening ports to the internet.
Build and simulate the configuration off site (FAT) before installation to shorten time on site.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Hand over configuration backups, point table, IP plan and as-built drawings, with a short operator training.

Project deliverables

Signed point table and protocol mapping
Gateway configuration files and backups
IP address plan and network drawing
FAT and SAT test records
As-built documentation and operator training

Architettura del sistema

Field layer: air handling units (AHU), lighting control panels, lift controllers, escalator controllers, pump controllers and starters, fire alarm panels (read-only), connected over Modbus TCP / Modbus RTU / BACnet/IP / S7. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the BMS, SCADA, the operations / command centre, which receives the data as BACnet/IP / OPC UA / IEC 60870-5-104. Remote access for maintenance runs over VPN rather than open internet ports.

Fasi di realizzazione

1
Site survey and point list
Inventory devices, protocols, register maps, panel space, power and network paths.
2
Design and point table sign-off
Map every point to the target protocol and system; agree it with the client and the upper-system contractor.
3
Configuration and FAT
Build the gateway configuration off site, simulate it and test against the signed point table.
4
Installation and wiring
Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.
5
SAT and alarm tests
Verify values against local readings, test every alarm and command end to end.
6
Handover and support
Hand over configuration backups, point table and as-built documents; train operators.

Valore per il cliente

One view of all subsystems instead of separate vendor consoles
Alarms reach the right person by SMS, email or messaging apps
New equipment integrated by configuration, not custom driver development
Timestamped records for compliance and reporting
