| High Light | Coal transportation GPS tracker with load sensor ，Real-time weight change GPS tracker ，Mobile DVR with load monitoring | ||
Designed specifically for coal transport operations, this integrated solution combines a 4G GPS tracker with a high-precision onboard load sensor to deliver real-time cargo weight monitoring and anti-theft protection. The system continuously measures load weight using capacitive sensing technology, transmits data via 4G network to a cloud platform, and triggers instant alerts for any unauthorized weight change — ensuring coal shipments arrive intact from mine to destination.
The capacitive sensor mounts on the vehicle frame without structural modification, detecting suspension deflection caused by load weight with 0.2mm accuracy. It connects to the 4G GPS tracker via standard interface, which transmits real-time weight data alongside GPS location, speed, and ACC status to the monitoring platform. Any abnormal weight fluctuation generates immediate alerts.
1. Real-Time Load Weight Monitoring
Continuous tracking of cargo weight during loading, transit, and unloading
Detects weight decrease (coal theft, leakage, unauthorized dumping) and weight increase (unauthorized loading)
0.2mm measurement error, 0.2% resolution for reliable data
2. Precise GPS/Beidou Tracking
Dual-mode satellite positioning with 5-meter accuracy
Real-time vehicle location, speed monitoring, and route history
ACC detection for ignition/extinguishment status
3. 4G Instant Data Transmission
Full 4G network compatibility for real-time weight and location uploads
Blind spot data storage (up to 30,000 records) with automatic re-transmission
Remote configuration and OTA firmware upgrades
4. Smart Alerts for Security & Compliance
Weight drop alert → theft, illegal dumping, or spillage
Weight increase alert → unauthorized loading
Overspeed alert (platform-set limit)
Low battery/power loss alert
Geofencing with route deviation detection
5. Fleet Management Capabilities
Fuel consumption monitoring (refueling/oil leakage detection)
Working hours statistics for operational efficiency
Positive/negative rotation detection (for mixer trucks)
Temperature/humidity monitoring (optional)
| Challenge | How This Solution Solves |
|---|---|
| Coal theft mid-route | Weight drop alerts with GPS location pinpoint the exact time and place |
| Illegal dumping | Unauthorized weight loss triggers instant notification |
| Overload violations | Real-time weight data prevents regulatory fines |
| Disputes on delivered quantity | Auditable weight logs provide objective evidence |
| Route compliance | GPS tracking verifies scheduled delivery paths |
