Negative Pressure Room Monitoring
Bài toán
Isolation rooms depend on a pressure difference that can be lost when a door is left open or a fan fails, and staff outside the room are not told.
Tổng quan giải pháp
MILESGO gateways collect data from differential pressure sensors, door contacts, air handling units (AHU), run/stop and fault dry contacts over Modbus RTU / BACnet MS/TP, and deliver it to the BMS, SMS, email and messaging alarms, WEB HMI panels as BACnet/IP / MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.
Typical scope
- differential pressure sensors
- door contacts
- air handling units (AHU)
- run/stop and fault dry contacts
Protocol path
Modbus RTU / BACnet MS/TP → BACnet/IP / MQTT
Implementation checklist for the project manager
- Monitoring does not replace certified medical or safety alarm systems; keep them in place and treat MILESGO data as supervisory.
- Keep sensor calibration certificates on file and plan recalibration intervals.
- 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.
- Agree data retention and the report format needed for audits with the quality team at the start.
- Confirm DIN-rail space and a stable 12–24 V supply in each panel; use UPS-backed power for critical monitoring.
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
Kiến trúc hệ thống
Field layer: differential pressure sensors, door contacts, air handling units (AHU), run/stop and fault dry contacts, connected over Modbus RTU / BACnet MS/TP. 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, SMS, email and messaging alarms, WEB HMI panels, which receives the data as BACnet/IP / MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

Các bước triển khai
- 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.
