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, electric vehicle remote management, 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, 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.
II.Scope of application of Vehicle Tbox 4G LTE:
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.III.Summary of Vehicle Tbox 4G LTE
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.Ⅳ. Function & feature of Vehicle Tbox 4G LTE
