The document discusses an axle load monitoring system that uses sensors mounted on a truck's air suspension to detect the weight on each axle. The sensors send analog signals to a digital converter that puts the data on the CAN bus. This data is then sent to the driver's display and a tracking device that uploads it to an online server. The system allows drivers to monitor axle weight during loading and unloading, and fleet managers to track location, route, and axle weights in real time to prevent overloading and cargo theft.
