Telematics Box HQT401
Telematics box, as the so-called t-box, vehicle black box or smart box, is being widely used in fields such as insurance, periodic tenancy, fleet management, driver behavior management, vehicle tracking & recovery...
Vehicle location monitoring, vehicle status monitoring, vehicle control, firmware upgrade, B-CALL, CAN Bus tachograph, remote diagnostics, driving behavior analysis, hotspot share, wireless communication, information encryption, vehicle anti-theft.
The Tbox 4G LTE can be installed under the dashboard, under the seat of driver and in the trunk. It can be fixed with screws, Velcro or by customized method. Adaptively powered by vehicle power 12V or 24V, it can interact with vehicle via CAN interface.
Tbox has been integrated with MCU, data storage module, GNSS module, wireless communication module, and CAN transceiver module. Meanwhile, the preserved interfaces support extension of external devices, such as infotainment screen, and all kinds of sensors.

Telematics box, as the so-called t-box, vehicle black box or smart box, is being widely used in fields such as insurance, periodic tenancy, fleet management, driver behavior management, vehicle tracking, and stolen vehicle recovery (SVR). The tbox makes a very important role in the whole telematics system.
In-house designed, developed and manufactured by Hopechart, one of the telematics device suppliers, the t-box HQT401 comes with GPS and GNSS positioning module, 4G LTE module, Wi-Fi hotspot, Bluetooth, internal battery, CAN Bus and RS232 ports. As the tbox HQT401 adopts design of vehicular gauge, it can stand extreme working environment and conditions. The tbox can realize vehicle remote tracking and monitoring, vehicle control, security detection and warning, vehicle remote diagnostics and breakdown call. Like our other tbox or tachograph products, the HQT401 can be also work together with the double Din Android multimedia screen.

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
