Railway Facility Monitoring

The problem

Trackside equipment rooms, substations and station buildings along the line are unmanned, and their power, cooling and intrusion alarms reach maintenance crews late.

Solution overview

MILESGO gateways collect data from UPS units, CRAC / CRAH precision air conditioners, electricity meters, door, intrusion and cabinet-open contacts, temperature and humidity sensors, generator controllers over Modbus RTU / Modbus TCP / SNMP, and deliver it to SCADA, the NMS (SNMP manager), SMS, email and messaging alarms as MQTT / SNMP / 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

UPS units
CRAC / CRAH precision air conditioners
electricity meters
door, intrusion and cabinet-open contacts
temperature and humidity sensors
generator controllers

Protocol path

Modbus RTU / Modbus TCP / SNMP → MQTT / SNMP / IEC 60870-5-104

Implementation checklist for the project manager

Check 4G signal and the SIM data plan at every site before committing to cellular backhaul.
Keep OT networks segregated and use VPN for remote access instead of opening ports to the internet.
For hard-wired signals, list each DI/DO/AI/AO with its type (dry contact, 4–20 mA, 0–10 V, PT1000) and choose I/O modules accordingly.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Standardise one configuration template per equipment type so further sites are copied, not rebuilt.
Fix a site / asset naming convention before the first site so data from all sites can be compared.

System architecture

Field layer: UPS units, CRAC / CRAH precision air conditioners, electricity meters, door, intrusion and cabinet-open contacts, temperature and humidity sensors, generator controllers, connected over Modbus RTU / Modbus TCP / SNMP. 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: SCADA, the NMS (SNMP manager), SMS, email and messaging alarms, which receives the data as MQTT / SNMP / IEC 60870-5-104. Remote access for maintenance runs over VPN rather than open internet ports.

System composition

Field devices: UPS units, CRAC / CRAH precision air conditioners, electricity meters, door, intrusion and cabinet-open contacts, temperature and humidity sensors, generator controllers
Edge / integration: MILESGO protocol gateways and edge controllers
Upper systems: SCADA, the NMS (SNMP manager), SMS, email and messaging alarms (MQTT / SNMP / IEC 60870-5-104)
Tools and commissioning: Web-based configuration, point table import/export (Excel), off-site simulation and on-site diagnostic tools

Delivery steps

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.

Customer value

Unattended sites supervised without permanent staff
Alarms reach the right person by SMS, email or messaging apps
Remote diagnosis and fewer site visits
Configuration templates reused across sites
