Cold Storage Monitoring

Masalahnya

Cold rooms hold high-value stock, but refrigeration controllers alarm only locally and temperature records for customers are exported by hand.

Ikhtisar solusi

MILESGO gateways collect data from refrigerators, freezers and cold room controllers, refrigeration case and rack controllers, PT100 / PT1000 temperature probes, door contacts, electricity meters over Modbus RTU / Modbus TCP, and deliver it to a cloud platform (MQTT), a historian / database (MySQL, SQL Server, InfluxDB), 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

  • refrigerators, freezers and cold room controllers
  • refrigeration case and rack controllers
  • PT100 / PT1000 temperature probes
  • door contacts
  • electricity meters

Protocol path

Modbus RTU / Modbus TCP → MQTT / OPC UA

Implementation checklist for the project manager

  • Agree data retention and the report format needed for audits with the quality team at the start.
  • Collect register maps and protocol documents from every equipment vendor early; a missing map is the most common delay.
  • Keep sensor calibration certificates on file and plan recalibration intervals.
  • Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
  • Confirm local storage so data survives network outages, and define the retention period.
  • Check 4G signal and the SIM data plan at every site before committing to cellular backhaul.

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: refrigerators, freezers and cold room controllers, refrigeration case and rack controllers, PT100 / PT1000 temperature probes, door contacts, electricity meters, 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: a cloud platform (MQTT), a historian / database (MySQL, SQL Server, InfluxDB), 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.

Nilai bagi pelanggan
