III. Core Functions

1. Real-Time Temperature Monitoring Across All Axles and the Entire Vehicle: Supports comprehensive monitoring of all axle positions on a tractor-trailer combination, simultaneously collecting temperature data from multiple axle heads, wheel hubs, and brakes. Data is continuously updated throughout the entire journey, accurately capturing temperature gradients during heavy-load braking and long downhill descents, with no monitoring blind spots.
2. Tiered Intelligent High-Temperature Warning and Protection: Features built-in temperature threshold strategies specifically designed for commercial vehicles, supporting a three-tier protection system comprising elevated-temperature warnings, high-temperature alerts, and extreme-temperature emergency alarms. It accurately identifies faults such as dry friction from dragging brakes, brake sticking, bearing damage, and thermal fade failure. The response logic is optimized for continuous braking scenarios in mountainous areas to proactively mitigate the risks of axle head fires and brake failure.
3. Local Visual Real-Time Display: The in-vehicle display shows the temperature of each axle in separate zones, providing an at-a-glance overview of the status. This eliminates the drawbacks of traditional systems—which lack displays and provide only alarms without data—allowing drivers to intuitively identify the faulty axle and the severity of the issue, and quickly take corrective actions such as slowing down or stopping to investigate.
4. Cloud-Based Remote Monitoring: 4G network connectivity enables real-time upload of axle temperature data. Fleet management systems can remotely monitor the condition of the vehicle’s wheel ends while in motion. Real-time pop-up alerts and SMS notifications are triggered for anomalies, and temperature data and alert records are automatically stored. The system supports route correlation and data review, enabling pre-event warnings, real-time monitoring, and post-event traceability.
5. Calibration-Free, Quick Adaptation: The magnetic sensors are ready to use immediately upon attachment, requiring no professional setup or complex calibration. They automatically adapt and recognize changes after trailer swaps or axle position adjustments, significantly reducing fleet maintenance labor hours and retrofitting costs.
6. Intelligent System Self-Diagnosis: The device performs a self-test upon power-up, continuously monitoring sensors, signal transmission, network communication, and power supply status. It automatically logs error codes to quickly troubleshoot issues such as signal loss or device malfunctions, ensuring stable 24-hour system operation.
