Deployment (Jetson)

Repo: https://git.proit.id/andrew/karung-counting-feedmill-semarang (git remote set-url origin <url> after the ervan → andrew transfer).

Systemd services

Unit	Runs	After
karung-counter.service	/usr/bin/python3 predict.py (cwd /home/jetson/karung, QT_QPA_PLATFORM=offscreen)	network.target
karung-counter-dashboard.service	/usr/bin/python3 counter_dashboard.py	network.target + counter
mediamtx.service	MediaMTX restream (see zones.json:external_stream_url)	—

Both app units: Restart=always, RestartSec=5, load EnvironmentFile=/home/jetson/karung/.env.

sudo systemctl enable --now karung-counter karung-counter-dashboard
sudo systemctl restart karung-counter karung-counter-dashboard
systemctl status karung-counter karung-counter-dashboard --no-pager

Deploy flow (deploy_to_jetson.py)

Paramiko sync of templates/{operator,monitoring,base}.html, counter_dashboard.py, predict.py, .env → 192.168.192.96:/home/jetson/karung/, then restarts both services and checks status + ports (5000/5721). Run from the dev machine.

TensorRT export

On the Jetson (needs CUDA): python3 export_model.py exports karung-dimuat-detection-di-feedmill-yolo26n-seg-200e.pt → FP16 .engine; export_v4.py is the v4-best variant. Point MODEL_PATH / loader constants at the .engine afterwards.

Runtime data files

• SQLite jetson_counter.db: batches(counting_date, batch_number, camera_name, object_label, count, start/end_time), daily_summaries(...).
• current_batch.json (crash recovery), batch_mode.json (manual/auto), batch_history_folder/batch_<ts>.json + hasil_perhitungan.json (per-batch reports).
• Live frame: /dev/shm/jetson-counter/live_frame.jpg (written every 2nd frame, consumed by /api/live-video MJPEG).
• Helpers: backup.py, dump_db.py, check_jetson_db.py, migrate_jetson_db.py, merge_batches_*.py, update_batches.py, diagnose_truck_jetson.py.

Dashboard (counter_dashboard.py)

Pages: / + /monitoring, /operator (manual start/stop, mode switch), /history, /analytics. Key APIs: /api/live-video, /api/current-batch, /api/previous-batch, /api/batch/{start,stop,mode}, /api/summary, /api/daily-data, /api/day-detail/<date>, /api/recent-batches, /api/available-dates, /api/export-daily-csv, /api/export-day-csv/<date> (CSV + Excel via openpyxl).
