Historical Track Playback: Query by Date and Playback Control
Feature Overview
Historical tracks let you query a device's position points within a time range and replay movement on the map. This is useful for issue investigation, process review, and customer feedback verification.
Steps
- Enter the historical track page and select a device at the top.
- Choose a date and, if necessary, narrow down the time range.
- After the query completes, the page displays a track summary such as start point, end point, mileage, and speed.
- Use playback controls to replay the route and combine it with the map to inspect key turns or stop areas.
Recommendations
- Start with the full-day range to confirm whether any track exists at all, then narrow the time range to the actual incident window.
- During review, look at alerts together with tracks for a more complete conclusion.
FAQ
Q: Why does the start point or end point show "Loading..." or incomplete location information?
A: Address resolution may need some time. Wait briefly and try again. If it still fails, check the network and retry.
