Data gathering

CANdata gathering

Can gather vehicle data through 3 channels of high speed CAN

Audio signal gathering

With noise suppression feature, support external passive MIC, support audio monitoring

Voltage gathering

Gather and report main battery voltage and backup battery capacity

Data storage

Real-time data storage

The collected real-time data can be saved into the Tbox internal storage medium based on interval of 10ms. These data can be readouton computer.

Datarecovering

If network disconnects, the real-time data will be

saved into the local storage medium and be resent to

the monitoring platform once network recovers.

Independentoperation

Tbox can continue to work when external power cuts off. The data of the first 30 minutes after power cuts off can be guaranteed to be sent to the platform.

Driverbehavior

Analyzing driver behavior in real time, the device will report the events to the back-office platform once detecting bad driving behavior, including harsh acceleration, harsh turn, harsh deceleration and cornering without light.

Devicemanagement
