Abstract

The invention relates to a vehicle driving recording device comprising a vehicle driving recorder and a power supply mechanism powering up the vehicle driving recorder; the power supply mechanism comprises a power supply management module, a host power supply and a spare power supply; the host power supply and the spare power supply are respectively connected with the power supply management module; the power supply management module is a low power management MCU; the spare power supply is a large capacity non-charging dry cell; said two can be combined to reduce the power consumption; the spare power supply is large in capacity, thus realizing a longer duration under the same conditions. When a vehicle is in an idle state for a long time in the prior art, the power of a vehicle storage battery may be used up, so the vehicle cannot be started and the vehicle driving recording device cannot be used; the vehicle driving recording device can solve said problems.

Description

technical field [0001] The invention relates to an automobile travel recorder device. Background technique [0002] Existing vehicle driving recorder comprises vehicle driving recorder, comprises vehicle driving recorder and the power supply mechanism that provides power for vehicle driving recorder, and power supply mechanism comprises power management module, host power supply and standby power supply, and host power supply and standby power supply are respectively connected with The power management module is connected, the host power supply is generally a 24V vehicle power supply, and the backup power supply is a rechargeable battery. When the ACC is turned on and the engine is ignited, the rechargeable battery is charged. Under the current technical situation, the vehicle is equipped with GPS / Beidou automobile After the driving recorder, communicate with the background server through the communication module, and send the current GPS / Beidou longitude and latitude positi...
