Predictive Fleet Monitoring

DrilLedger's Fleet Monitoring Agent uses vehicle telematics — a J1939 gateway on trucks and heavy plant, an OBD-II gateway on light utes — over Starlink connectivity to track engine temperature, oil pressure, coolant levels and fault codes in real time. When a reading crosses a threshold, or drifts the wrong way at the same engine load, rule-based checks raise an alert and the service booking — so the fix can be planned in downtime instead of becoming an $8,000-$15,000 emergency callout to Newman, Tom Price, or Kalgoorlie. The rules are readable, not a black box, and a fitter confirms every diagnosis.

Most WA mine sites have limited or no cellular coverage, so the gateway reports over 4G/LTE in transit and picks up Starlink at camp or depot — keeping trucks reporting across the Pilbara, Goldfields, and Mid West without a fixed signal. If the satellite link drops, the gateway streams live rather than storing on the truck, so you lose those minutes of readings, not the record. Monitoring resumes automatically when the link is back, and the gap never corrupts a vehicle history or a fuel-trial result.

Unplanned breakdowns on remote mine sites typically cost $8,000-$15,000 per incident — including emergency towing, specialist mechanic callout, replacement vehicle hire, and lost production. WA mining suppliers with 20-50 vehicles experience 4-8 preventable breakdowns per year. That's $24,000-$60,000 in avoidable costs annually.

The system supports any vehicle or equipment with OBD-II diagnostics — light vehicles, service trucks, water carts, fuel trucks, and support vehicles used on WA mine sites. It also supports auxiliary equipment monitoring via aftermarket sensor packs for generators, compressors, and pumps.

Service scheduling, compliance inspections, and vehicle history are automated. Instead of admin staff manually tracking service intervals on spreadsheets, the agent calculates service due dates from actual engine hours and kilometres, sends alerts to drivers and mechanics, and maintains a digital service history. This saves approximately 200 hours of admin per year for a 30-vehicle fleet.

WHS (Mines) Regs 2022 Reg 213 puts the duty on the person with management or control of plant to ensure maintenance, inspection and testing is carried out by a competent person, and Reg 237 requires a written record of every test, maintenance event and inspection for the period the plant is used. The agent records every Starlink-streamed telemetry sample, every alert acknowledged, every service action and every pre-start inspection against the vehicle and the actor — actor, timestamp, fault code, action, on every event. When WorkSafe (LGIRS) asks for the Reg 237 record on a specific vehicle, it is one filter and one export, not six PDFs across three laptops.

Yes. The agent tracks cumulative engine hours, kilometre readings, maintenance costs, and breakdown frequency per vehicle. It projects when each vehicle will reach its optimal replacement point based on rising maintenance costs vs residual value — helping fleet managers plan capital expenditure rather than reacting to breakdowns.
