Description

Time & date

Time & date

Provide time and date (accurate to 1ms)

Automatic self-check

Automatic time correction, error less than 5s per day

Positioning

Support GPS/BD positioning and A-GPS, accuracy 5m. Support mobile base tower positioning.

Communication

Mobile telecom

FDD-LTE/ TDD-LTE/ TD-SCDMA/ UMTS/ EDGE/ GSM/ EVDO/ CDMA

SMS

Support parameter inquiry and setup by sending SMS order.

Multi-platform connection

Support connection with two or more platforms. Support sending different data to different platforms.

BT

Bluetooth 4.0 BLE, for data communication

Data gathering

CAN data 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 readout on 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.

Independent operation

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.

Driver behavior

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.

Device management

Power management

Five modes: working mode, monitoring mode, sleep

mode, off mode, storage mode

Self-check

When being powered on and used, device will automatically check status of GPS and network and display the status by LED indicators.

Device control

Support remote and local program upgrading, parameter configuration and etc.

Data interaction

USB

Data export, parameter configuration and local upgrading, communication with display screen.

RS232

Parameter configuration, connection with external sensors.

CAN

Communication withCAN Bus and vehicle body.

Support ISO 11898and SAE J1939.

Hardware encryption

Support SM3, SM4, universal symmetric algorithm and asymmetric algorithm.

OTA

Support upgrading other ECUs of vehicle, which need to be confirmed with ECU manufacturers.

B-CALL

Support breakdown call
