Reefer Container Monitoring

ปัญหา

Reefer stacks in a yard are checked by walking the rows, so a tripped plug or an alarm on one container can go unnoticed for hours.

ภาพรวมโซลูชัน

MILESGO gateways collect data from reefer container controllers (via the terminal monitoring interface), electricity meters, run/stop and fault dry contacts over Modbus RTU / Modbus TCP, and deliver it to SCADA, third-party platforms (HTTP API), SMS, email and messaging alarms as 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

  • reefer container controllers (via the terminal monitoring interface)
  • electricity meters
  • run/stop and fault dry contacts

Protocol path

Modbus RTU / Modbus TCP → MQTT / OPC UA

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.
  • RS-485: shielded twisted pair, daisy-chain topology, termination at both ends, up to 32 nodes per segment without a repeater.
  • Outdoor sites need a weatherproof, ventilated enclosure with surge protection; the gateways are panel-mount devices (working range -20 °C to +70 °C).
  • Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
  • 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

สถาปัตยกรรมระบบ

Field layer: reefer container controllers (via the terminal monitoring interface), electricity meters, run/stop and fault dry contacts, connected over Modbus RTU / Modbus TCP. 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, third-party platforms (HTTP API), SMS, email and messaging alarms, which receives the data as MQTT / OPC UA. Remote access for maintenance runs over VPN rather than open internet ports.

ขั้นตอนการส่งมอบ

  1. 1

    Site survey and point list

    Inventory devices, protocols, register maps, panel space, power and network paths.

  2. 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. 3

    Configuration and FAT

    Build the gateway configuration off site, simulate it and test against the signed point table.

  4. 4

    Installation and wiring

    Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.

  5. 5

    SAT and alarm tests

    Verify values against local readings, test every alarm and command end to end.

  6. 6

    Handover and support

    Hand over configuration backups, point table and as-built documents; train operators.
