Задача
The engine puts out codes and numbers over the J1939 bus, and my mechanic says he can't read any of it without a service laptop. Give me a tool where I load the frames and it tells me in plain language: here's the temperature, here's the oil pressure, here are the active faults.
План решения
What We'll Build
- A J1939 decoder web app where you upload raw CAN frame logs and instantly see parsed values in plain English: coolant temp, oil pressure, RPM, fuel rate, and more.
- A fault code interpreter that maps active DTCs (Diagnostic Trouble Codes) against standard J1939 SPN/FMI tables and explains each fault in plain language — no service laptop, no manual lookup.
- A clean dashboard displaying live or historical parameter trends, with red/yellow alerts for out-of-range values.
How It Works
- Raw J1939 frames (from a CAN logger, SD card export, or serial dongle) are parsed against PGN/SPN definitions per SAE J1939-71/73 standards.
- Processing runs in the browser or on a lightweight edge service — no proprietary software required; output delivered via simple web UI or CSV export.
- Fault descriptions pull from a curated SPN/FMI database covering the most common marine and industrial engine families.
Next Step
Upload a sample log file and your engine's make/model in our project workspace — we'll validate coverage against your specific PGNs and scope the build within one working day.
