Abstract
An acceleration-based mobile asset data recorder and transmitter equipped with a wireless processing unit, an event recorder, a digital video recorder, a fuel level sensor, and an inertial navigation sensor board. The inertial navigation sensor board includes a 3-axis gyroscope, a 3-axis accelerometer, a 3-axis magnetometer, and a microcontroller. The data recorder and transmitter allows for automatic orientation, automatic compass calibration, fuel compensation with pitch and roll, emergency brake application with impact detection, rough operating condition detection, engine running detection, and inertial navigation of a mobile asset. Users can use the normal operation of their mobile assets to locate and alert, in real-time, areas where their assets are encountering rough operating environments, to provide for quicker emergency response, and to validate the effectiveness of repairs and rerouting.
