Reefer Container Monitoring

Masalahnya

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.

Ikhtisar solusi

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

Arsitektur sistem

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.

Langkah pelaksanaan

  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.
