Abstract
A system for tracking and monitoring the intermodal status of cargo trailers. In addition to the information provided by a Global Positioning System (GPS) unit, the system monitors the status of various sensors on the trailer. The GPS unit provides the location and velocity of a trailer. A wheel monitoring unit provides the status of the wheels of the trailer, specifically whether there is rotation of the wheels or not. Anti-lock braking systems are used to provide signal information indicative of the wheel rotation status. An independent wheel rotation sensor is also used to provide the wheel rotation status. A computer processor determines the intermodal movement status of the trailer using the wheel rotation status and the location and velocity information.
