Rack Environment Monitoring

Il problema

Room sensors show an average temperature while individual racks overheat, and open doors or smoke inside a cabinet are not reported at all.

Panoramica della soluzione

MILESGO gateways collect data from temperature and humidity sensors, PT100 / PT1000 temperature probes, door contacts, smoke detector contacts over Modbus RTU, and deliver it to the DCIM, the NMS (SNMP manager), SMS, email and messaging alarms as SNMP / MQTT / BACnet/IP. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

temperature and humidity sensors
PT100 / PT1000 temperature probes
door contacts
smoke detector contacts

Protocol path

Modbus RTU → SNMP / MQTT / BACnet/IP

Implementation checklist for the project manager

Agree sensor positions (height, airflow, distance from doors and diffusers) so readings are representative.
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.
RS-485: shielded twisted pair, daisy-chain topology, termination at both ends, up to 32 nodes per segment without a repeater.
Fix a site / asset naming convention before the first site so data from all sites can be compared.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Keep sensor calibration certificates on file and plan recalibration intervals.

Architettura del sistema

Field layer: temperature and humidity sensors, PT100 / PT1000 temperature probes, door contacts, smoke detector contacts, connected over Modbus RTU. 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 DCIM, the NMS (SNMP manager), SMS, email and messaging alarms, which receives the data as SNMP / MQTT / BACnet/IP. 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.
