Description
Technical field
The present invention relates to a kind of automobile travel recorder devices.
Background technology
Existing automobile traveling recording device includes automobile travel recorder, including automobile travel recorder and is garage
The power supply mechanism that recorder provides power supply is sailed, power supply mechanism includes power management module, host power supply and stand-by power supply, host electricity
Source and stand-by power supply are connect respectively with the power management module, and host power supply is generally 24V vehicle power supplies, and stand-by power supply is can
Rechargeable battery charges in the case where ACC opens i.e. engine ignition to rechargeable battery, under current technology status, vehicle
It after GPS/ Big Dipper automobile travel recorders are installed, is communicated by communication module and background server, in real time by current GPS/ north
Bucket longitude and latitude position is sent to server.But rechargeable battery, power consumption itself is big, and self-discharge of battery is fast, especially long in vehicle
In the case that time does not use, the battery power of vehicle may be caused to exhaust, can not start vehicle and automobile travel recorder without
The technical issues of method uses.
Invention content
The present invention provides a kind of automobile traveling recording device, to solve existing automobile traveling recording device in vehicle long-time
In the case of not using, the battery power of vehicle may be caused to exhaust, can not start vehicle and automobile travel recorder can not make
The technical issues of using.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of automobile traveling recording device provides power supply including automobile travel recorder and for the automobile travel recorder
Power supply mechanism, the power supply mechanism includes power management module, host power supply and stand-by power supply, the host power supply and spare
Power supply is connect respectively with the power management module, it is characterized in that, the power management module manages MCU for low-power consumption, described
Stand-by power supply is the non-Rechargeable dry battery of large capacity.
Typical chip used in the low-power consumption management MCU：STM8L151 family chips/MSP430 family chips.
The host power supply is 24V vehicle power supplies.
The large capacity refers to that electricity is more than 700mAh.
The low-power consumption refers to that electric current is less than 5mA.
After above-mentioned technical proposal is employed, since power management module is that low-power consumption manages MCU, the stand-by power supply
For the non-Rechargeable dry battery of large capacity.The two combination can make power consumption small, and stand-by power supply capacity is big, so as to which stand-by power supply be made to exist
The longer time is used under equal conditions, solves existing automobile traveling recording device in the case where vehicle does not use for a long time,
The battery power of vehicle may be caused to exhaust, vehicle can not be started and the technical issues of automobile travel recorder can not use.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
As shown in Figure 1, a kind of automobile traveling recording device, carries including automobile travel recorder and for automobile travel recorder
The power supply mechanism of power supply source, power supply mechanism include power management module, host power supply and stand-by power supply, host power supply and standby electricity
Source is connect respectively with power management module, and power management module manages MCU for low-power consumption, and stand-by power supply is dry for the non-charging of large capacity
Battery, typical chip used in low-power consumption management MCU：STM8L151 family chips/MSP430 family chips, host power supply 24V
Vehicle power supply.Wherein large capacity refers to that electricity is more than 700mAh, and low-power consumption refers to that electric current is less than 5mA.
Power supply control management method be：
A, it is in the case that 24V vehicle power supplies disconnect to be disconnected in automobile travel recorder external power supply：
The non-Rechargeable dry battery of large capacity is operated in suspend mode to low-power consumption management MCU power supplies, low-power consumption management MCU most cases
Under pattern, quiescent current is microampere order, and as twice, specific wake-up times can be set daily timing wake-up according to application scenarios,
Low-power consumption management MCU opens automobile travel recorder host power supply immediately after waking up, by current longitude and latitude and each I/O state reportings
Central server, general work 3 minutes, then reenters dormant state.
B, the 24V vehicle powers in the case where automobile travel recorder external power supply is connected：
In the case where there is the main electricity of 24V vehicles, the non-Rechargeable dry battery management automobile travel recorder circuit part of large capacity
It is whether powered-down, in the case where ACC opens i.e. igniting, low-power consumption management MCU and Tachographs electricity are supplied electricity to using the vehicle master of 24V
Road works, and in the case where ACC closes i.e. engine misses, Tachographs circuit is closed, using the non-Rechargeable dry battery of large capacity
Power supply, into dormant state；
C, in the case of vehicle accumulator brownout, such as 24V vehicle powers, but when virtual voltage is less than 18V,
Automatic to start storage battery low-voltage variation function, the power supply for not using vehicular power-bottle is powered to automobile travel recorder, in order to avoid storage battery
It is under-voltage to cause vehicle that light a fire startup.
Since power management module is low-power consumption management MCU, stand-by power supply is the non-Rechargeable dry battery of large capacity.The two combines
Power consumption can be made small, stand-by power supply capacity is big, so as to which stand-by power supply be made under equal conditions using the longer time, to solve
Existing automobile traveling recording device may cause the battery power of vehicle to exhaust, nothing in the case where vehicle does not use for a long time
The technical issues of method startup vehicle and automobile travel recorder can not use.
