Built-in WIFI module, supports hotspot sharing;

Comply with vehicle manufacturers’ EMC and EMI requirements;

Vehicle OBD information collection: After the monitoring vehicle engine is started and before the vehicle is driven, the vehicle terminal collects the OBD diagnostic information of the vehicle at least once within 24 hours and uploads the read information to the management platform.

Vehicle data collection: It can collect data related to new energy vehicles and engine emissions according to the specified collection frequency, and automatically identify invalid data sent by the NOx sensor when the normal working conditions are not met.

Vehicle information data storage function: The collected information data can be stored in the internal storage medium, and can be automatically overwritten when the internal storage medium is full.

Data transmission: The collected vehicle status data can be uploaded to the monitoring center at specified time intervals. The type of data uploaded meets the requirements of new energy and emission standards.

Data re-issuance: When communication is abnormal, T-BOX can store the collected data locally and re-send it after the communication returns to normal.

Remote control: T-BOX has functions such as self-test, remote query, remote parameter setting, and remote upgrade.

Telematics Control Unit (T-box)
Sleep function: T-BOX has vehicle ACC ignition detection function. When the vehicle is turned off, T-BOX will send a signal to the monitoring center and enter sleep mode.

UDS diagnosis: designed in accordance with the requirements of the ISO15765-"Diagnostics on CAN" protocol, and realized the entire system framework from the data link layer to the application layer in the OSI layer required by the protocol.

OSEK network management: based on the direct network management (Direct Network Management) stipulated in OSEK network management (V2.5.3). Under the control of the ring building algorithm, T-BOX can build a stable logical ring with other NM nodes, and through the control of the sleep negotiation algorithm, it can coordinate and synchronize with other nodes in the network to enter the sleep state.

BootLoader program flashing: Based on the UDS diagnostic system, under the control of the external Tester, complete the update of the application program and data on the T-BOX.

Telematics Control Unit (T-box)
Multi-center access function: It supports connecting two or more monitoring centers at the same time, and can obtain the information issued by the monitoring centers.

Alarm function: the terminal supports battery undervoltage reminder, power failure reminder, terminal failure reminder, line reminder, overspeed warning/alarm reminder, etc.

Driving behavior analysis: It can collect vehicle braking, turning and other information to detect the driver's bad driving behavior, including: rapid acceleration, rapid deceleration, sharp turns, sharp roads, collisions, etc. When the above behavior occurs, it can be reported to the monitoring platform immediately.

Supports "cloud" guardian functions such as remote automatic program maintenance, remote fault diagnosis and debugging, remote parameter configuration, and terminal operation statistics to improve equipment installation and maintenance efficiency and save maintenance time and costs.
