VarOBU - Automatic Brake Test with Mobility 4.0

VarOBU is a Mobility 4.0 application. This includes an on-board unit for the wireless, secure transmission of sensor data from the braking system to the locomotive. The locomotive driver receives the result of the braking test on his mobile terminal via wireless transmission, whether he is at a standstill or while driving.

Additional data from the brake test are available in a cloud-based solution for reporting and long-term archiving. Every user is provided with the information intended for them via the integrated rights management system. The security of your data takes top priority for us here.
