The operation
A captive iron ore mine of an integrated steel producer.
Excavators, tippers, loaders and support vehicles from several manufacturers.
Diesel issued from mobile bowsers. Cellular coverage drops on the lower benches.
The problem
Diesel issued at the bowser and diesel recorded against machines were reconciled from slips at month end. Any difference could not be traced to a machine or a shift, and machines on the lower benches went silent for parts of each shift.
How the work is phased
In detail
- Fuel sensing
- Capacitive tank sensors, calibrated tank by tank
- Dispensing
- RFID authorisation at the nozzle, volume from the flowmeter
- Engine data
- CAN bus where the manufacturer exposes it
- Coverage
- 4G with LoRaWAN for the lower benches
- Reporting
- Issue against burn, per machine and per shift
What changes on site
Issue and burn on one record, per machine and per shift
Drains flagged against a machine during the shift
Fuel released only to tagged machines
LoRaWAN carries data where 4G does not reach
