Railway Facility Monitoring

Il problema

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

Panoramica della soluzione

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.

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: 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.

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
