Supermarket Refrigeration Monitoring

Masalahnya

A failed display case or compressor rack overnight means discarded stock and food-safety risk, but case controllers only alarm on their own display.

Ikhtisar solusi

MILESGO gateways collect data from refrigeration case and rack controllers, PT100 / PT1000 temperature probes, electricity meters, door contacts over Modbus RTU, and deliver it to a cloud platform (MQTT), SMS, email and messaging alarms, a historian / database (MySQL, SQL Server, InfluxDB) as MQTT / BACnet/IP. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

refrigeration case and rack controllers
PT100 / PT1000 temperature probes
electricity meters
door contacts

Protocol path

Modbus RTU → MQTT / BACnet/IP

Implementation checklist for the project manager

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.
Agree data retention and the report format needed for audits with the quality team at the start.
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.
Standardise one configuration template per equipment type so further sites are copied, not rebuilt.

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: refrigeration case and rack controllers, PT100 / PT1000 temperature probes, electricity meters, door contacts, connected over Modbus RTU. 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), SMS, email and messaging alarms, a historian / database (MySQL, SQL Server, InfluxDB), which receives the data as MQTT / BACnet/IP. Remote access for maintenance runs over VPN rather than open internet ports.

Langkah pelaksanaan

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.
