Defined   as a severe collision scenario, reporting collision alarms, including   collision time, GPS information, collision acceleration

Trailer   alarm

The   vehicle is towed and reported to the trailer for warning, including trailer   time and GPS information.

Fatigue   driving reminder

The   vehicle travels for too long and automatically recognizes the fatigue driving   reminder.

Device   insertion alarm

The   terminal device is inserted and the alarm is reported.

Device   pull-out alarm (optional)

The   terminal device is pulled out, and the alarm is reported and pulled out (when   the backup power is available).

Long   positioning time

In   the case of vehicle ignition, the positioning time exceeds the settable time   threshold.

Reporting   the positioning time is too long, including alarm time and GPS information.

Driving   behavior

Driving   behavior

Including   driving cycle start terminal time, driving cycle total mileage, average   speed, maximum speed, overspeed duration,

Speed   number, idle time, rapid acceleration, rapid deceleration, sharp turn   information.

Driving   behavior event

During   the running of the vehicle, sudden acceleration, sudden deceleration, and   sharp turn events are generated, and the incident is reported separately.

OBD   data function

Vehicle   data flow

Report   the vehicle's critical data stream every 30S,

The   number of specific data items varies slightly depending on the vehicle data   support.

Reading   vehicle failure

The   terminal identifies the vehicle fault information, and reports the platform   when the vehicle fault state changes.

Clear   vehicle breakdown

Clear   the vehicle fault by issuing instructions from the platform.

Remote   management capabilities

Remote   upgrade

The   terminal software can be remotely upgraded through the GPRS network and   upgraded through the FTP server.

Remote   restart

The   device is restarted by sending a command in the data channel mode.

Remote   query

The   platform remotely queries terminal information, vehicle type, GPRS communication   parameters, heartbeat parameters, GPS/CAN return parameters, SIM card   information, GPS information, CAN data stream, and current faults through the   mobile network.
  Various alarm parameters, rapid acceleration and rapid deceleration sharp   turn parameters.

Remote   setting

The   platform remotely sets terminal information, vehicle type, GPRS communication   parameters, heartbeat parameters, GPS/CAN return parameters, clear vehicle   faults, control restart, factory reset, clear blind zone data, various alarm   parameters, and rapid acceleration and deceleration through the mobile   network. Sharp turn parameters.

Version   report

The   version information is reported every time ACC ON. The platform checks the   car version information by instruction.

SIM card information   reporting

Each time   ACC ON reports information such as the IMEI number of the SIM card.

The   platform checks information such as the IMEI number of the SIM card through   instructions.

Module   self-test

Terminal   status self-test: detect each function module (positioning module, bus   module, FLASH, 3D module)

Whether   it is working properly and its alarm occurrence (when it is not related to   wireless communication)

Backup   power

A slow flash   indicates that it is online.

It is often   dormant or not powered.

GPS light

Steady on,   indicating that the positioning is successful;

Slow flashing   indicates positioning;

Flashing   indicates that the module is abnormal.

It is often   dormant or not powered.

OBD light

Blinking   indicates successful communication with the car;

Off means that   the vehicle is not communicating or is sleeping or not powered.

Note: The three-color   lights are switched in 5 second intervals according to the   "red-green-blue" sequence.
