Elevator & Escalator Monitoring
ปัญหา
Lift and escalator status sits in the vendor’s own system, so the control room learns about a trapped passenger or a stopped escalator by phone.
ภาพรวมโซลูชัน
MILESGO gateways collect data from lift controllers, escalator controllers, run/stop and fault dry contacts over Modbus RTU / Modbus TCP / SNMP, and deliver it to the BMS, the operations / command centre, SMS, email and messaging alarms as BACnet/IP / OPC UA / MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.
Typical scope
- lift controllers
- escalator controllers
- run/stop and fault dry contacts
Protocol path
Modbus RTU / Modbus TCP / SNMP → BACnet/IP / OPC UA / MQTT
Implementation checklist for the project manager
- Where equipment only offers a vendor API or cloud, confirm access rights, data rate and costs with the vendor before design.
- Collect register maps and protocol documents from every equipment vendor early; a missing map is the most common delay.
- Commission in read-only mode first; enable write / control points only after the client approves each one.
- Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
- 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.
- 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
สถาปัตยกรรมระบบ
Field layer: lift controllers, escalator controllers, run/stop and fault dry contacts, 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: the BMS, the operations / command centre, SMS, email and messaging alarms, which receives the data as BACnet/IP / OPC UA / MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

ขั้นตอนการส่งมอบ
- 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.
