Vehicle Data Platform Product Spec
Visual Direction
The UI is a professional vehicle data operations console. It uses Semi UI as the component base, a restrained gray-white control-room palette, dense but readable tables, right-side drawers for detail, and blue-cyan accents for primary actions. It should feel closer to a cloud data console than a marketing dashboard.
Primary Screens
- Dashboard: KPI summary, protocol distribution, vehicle map preview, quality issues, and link health.
- Vehicles: table-first identity and vehicle registry.
- Realtime: table/map switch for current vehicle state.
- Vehicle Detail: identity header and tabs for latest state, history, raw, mileage, and quality.
- History: location and raw-frame query workspace.
- Mileage: daily and range mileage analysis.
- Quality: data quality and link health workspace.
Domain Principle
The product model is vehicle-first. GB32960, JT808, and Yutong MQTT are ingestion sources for one vehicle service, not separate business products. The UI should lead with VIN, plate, online state, location, mileage, and data quality; protocol appears only as source attribution, diagnosis, and raw-frame traceability.
Vehicle service coverage is always shown at VIN level. A vehicle may have one or more ingestion sources, but upper product views should summarize source count, online source count, last seen time, and binding status before drilling into protocol-specific diagnostics.
Vehicle lists should expose a vehicle-level service status derived from binding and source coverage: identity required, no data source, offline, degraded, or healthy. Protocol tags remain attribution and troubleshooting context, not the primary status.
Interaction Rules
- Tables are the default data surface.
- Filters stay above the table.
- Details open in a right drawer unless a full route is needed.
- Error and empty states must be explicit.
- No decorative hero, no oversized marketing card layout, no dark large-screen style.
