From 3797a4e2cad0046ff2f1c149c773162b9affbed1 Mon Sep 17 00:00:00 2001 From: David Kiania Date: Fri, 10 Apr 2026 22:46:00 +0300 Subject: [PATCH] Implement POLL-01 high-res GPS trails and POLL-03 on-demand location refresh POLL-01 (FIX-M14): Add poll_track_list() calling jimi.device.track.list - Runs every 30 min with 35-min lookback window (5-min overlap prevents gaps) - Inserts all device waypoints into position_history with source='track_list' - Increases position density from ~1/min to 2-6 fixes/min per active vehicle - Single shared DB connection for all devices per cycle (efficient) POLL-03 (FIX-M15): Add get_device_locations() utility function - Calls jimi.device.location.get for up to 50 specific IMEIs on demand - Used for alarm enrichment, stale device recovery, dashboard precision refresh Manual updates: - position_history section rewritten to document dual ingestion sources - Three new queries: data density check, harsh driving detection, route trace - Known Data Issues: issues 10 and 11 added and marked Fixed - API coverage table updated to reflect all three endpoints now in use Co-Authored-By: Claude Sonnet 4.6 --- ingest_movement_rev.py | 163 +++++++++++++++++++++++++++++++++- tracksolidApiDocumentation.md | 7 +- tracksolid_DB_manual.md | 91 ++++++++++++++++++- 3 files changed, 254 insertions(+), 7 deletions(-) diff --git a/ingest_movement_rev.py b/ingest_movement_rev.py index c3e46b4..95ba13d 100644 --- a/ingest_movement_rev.py +++ b/ingest_movement_rev.py @@ -21,6 +21,15 @@ REVISIONS (QA-Verified): [FIX-M13] POLL-02: Parking poll was returning 0 rows — added missing acc_type=0 and account params; fixed response field durSecond (was mapped as 'seconds'). + [FIX-M14] POLL-01: New poll_track_list() — calls jimi.device.track.list + per device every 30 minutes to capture high-resolution GPS + waypoints between the 60-second fleet sweep snapshots.
