Abstract
A system and method for transmitting a triggered alarm is presented. The alarm is detected by a sensor on an asset that includes a circuit containing a global positioning system (GPS) receiver, a wireless communication unit, a processing unit, a sensor unit and a storage unit operably coupled to one another. The storage unit comprises locations of the asset on a predefined route where events (such as, for example, a door of an asset opening) are expected and the wireless communication unit comprises a wireless transmitter and a wireless receiver. The sensor monitors a portion of the asset (such as, for example, the doors of the asset) while the asset travels along the predefined route. If the portion of the asset triggers an alarm, a current location of the asset is received via the GPS receiver and the event is compared with the locations of the asset on the predefined route. If the event is not expected at the current location, the wireless transmitter sends the alarm and the event to a data processing system.
