Hospital Energy Management
Problem
A hospital runs 24/7 with high HVAC and steam loads, but energy is known only from monthly bills, so savings projects cannot be targeted or verified.
Opis rozwiązania
MILESGO gateways collect data from electricity meters, BTU / heat meters, steam flow meters, gas meters, water meters over Modbus RTU / M-Bus / BACnet/IP, and deliver it to the energy management system, the BMS, large-screen dashboards (HDMI) as BACnet/IP / MQTT / OPC UA. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.
Typical scope
- electricity meters
- BTU / heat meters
- steam flow meters
- gas meters
- water meters
Protocol path
Modbus RTU / M-Bus / BACnet/IP → BACnet/IP / MQTT / OPC UA
Implementation checklist for the project manager
- Record CT ratios, meter IDs and multipliers in the point table; wrong multipliers are the usual cause of billing errors.
- M-Bus: check unit loads and cable length per segment; 2-wire M-Bus gateways need a 24 V DC supply.
- Agree KPI definitions (for example OEE components or kWh per unit) with operations before building dashboards.
- Fix a site / asset naming convention before the first site so data from all sites can be compared.
- Monitoring does not replace certified medical or safety alarm systems; keep them in place and treat MILESGO data as supervisory.
- 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
Architektura systemu
Field layer: electricity meters, BTU / heat meters, steam flow meters, gas meters, water meters, connected over Modbus RTU / M-Bus / BACnet/IP. 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 energy management system, the BMS, large-screen dashboards (HDMI), which receives the data as BACnet/IP / MQTT / OPC UA. Remote access for maintenance runs over VPN rather than open internet ports.

Etapy wdrożenia
- 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.
