Remote Technician

An engine is working right now, and a warning light comes on. Is it serious? Does the machine have to stop? To really know, someone had to drive out to it and hook a laptop into the bus — time, a person, and until then no certainty that the fault is even real. From emd-cloud — also called SIG — Remote Technician opens a live connection to that machine’s Dragonfly and shows its CAN bus in real time, with no one going anywhere.

Validate what is really happening

The session opens on what the asset actually reports: how many ECMs sit on the bus, the serial number and calibration of each one, and which fault codes are genuinely active as opposed to inactive.

That distinction is the whole point. A haul truck showing an amber warning lamp with the stop lamp off is reporting SPN 97 — water in fuel — at FMI 3. It is a warning, not a stop. The engine keeps running, the repair gets scheduled, and nobody halts the mine or sends a technician out in a rush.

Watch it operate, live

Engine parameters are decoded in the browser as they arrive, down to the millisecond. Engine speed, actual percent torque and the rest of what the ECM publishes plot in real time while the machine works under load — the view a technician would have standing right next to the engine. Nothing has to break first: every engine can be watched operating, live, always.

The DBC never leaves the browser

Decoding runs against the DBC provided by emd, or against a DBC of the client’s own. A client DBC is loaded in the browser and never leaves the operator’s machine, so proprietary parameter definitions stay where they are. The tunnel between that machine and the unit is point-to-point, low-latency and ultra-secure.
