摘要:
This invention comprises a mobile asset cellular device transmission detector equipped, a wireless processing unit, an event recorder, and a digital video recorder. The wireless processing unit includes event recorder interface software, digital video recorder interface software that obtains data from the digital video recorder, Wi-Nav software that obtains data from the Wi-Nav, GPS software that obtains data from the GPS and geo-fence software. The cellular device transmission detector continually checks for cellular device transmissions within the mobile asset and if those transmissions were associated with an impact, rollover, operator action or geo-fence defined location or boundary. When a cellular device transmission was made, the wireless processing unit triggers an episode and sends event recorder information, GPS location and speed, audio and video recordings, and impact and rollover information to a back office.
