Grain Silo Monitoring

Problem

Grain heats up from the inside, and hand-held checks at the silo top miss hot spots until spoilage has started; aeration fans run on guesswork.

Opis rozwiązania

MILESGO gateways collect data from grain temperature cables and aeration fans, temperature and humidity sensors, PT100 / PT1000 temperature probes, electricity meters over Modbus RTU, and deliver it to a cloud platform (MQTT), WEB HMI panels, SMS, email and messaging alarms as MQTT / Modbus TCP. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

grain temperature cables and aeration fans
temperature and humidity sensors
PT100 / PT1000 temperature probes
electricity meters

Protocol path

Modbus RTU → MQTT / Modbus TCP

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.
Write the control sequence (start/stop order, interlocks, set-points, fallback on communication loss) and have it approved before programming.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Outdoor sites need a weatherproof, ventilated enclosure with surge protection; the gateways are panel-mount devices (working range -20 °C to +70 °C).
Confirm local storage so data survives network outages, and define the retention period.

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

Architektura systemu

Field layer: grain temperature cables and aeration fans, temperature and humidity sensors, PT100 / PT1000 temperature probes, electricity meters, 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), WEB HMI panels, SMS, email and messaging alarms, which receives the data as MQTT / Modbus TCP. Remote access for maintenance runs over VPN rather than open internet ports.

Etapy wdrożenia

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.
