Description
Technical field
The present invention relates to in-vehicle multi-media system technical field of memory more particularly to a kind of in-vehicle multi-media system EMMC to deposit
Store up the method and apparatus of the filling map datum of member batch.
Background technique
With the raising of automobile popularity rate, the peripheral hardware storage accessory of vehicle multimedia navigation system becomes also more and more,
Wherein, for the stability for improving vehicle mounted guidance function, the external SD card for storing map datum is also gradually converted into performance more
Stable built-in patch formula EMMC chip so that the navigation feature error rate of onboard system is lower.But in-vehicle multi-media system
OEM vendor faces the problem of filling map datum heavy workload of EMMC means of storage, low efficiency simultaneously.
Fig. 1 show existing in-vehicle multi-media system host storage inside schematic diagram, 1) is navigation host in figure, and 2) be
CPU primary processor handles navigation engine；3) it is USB interface, connects external USB flash disk equipment；It 4) is EMMC storage chip, storage is led
Navigate map datum.
The way of OEM vendor is to connect navigation map data by USB after producing finished product vehicle multimedia navigation at present
Mouth is transferred in system in EMMC storage chip；Due to map data file at least 4G or more, lead to every navigation host burning
The map data file time is thirty minutes long.This method efficiency for manufacturing industry is very low, influences ETCD estimated time of commencing discharging out.
Summary of the invention
Goal of the invention of the invention is to provide a kind of in-vehicle multi-media system EMMC means of storage bulk filling map number
According to method and apparatus, solve existing navigation map data using technical solution provided by the invention and be transferred to EMMC in system
The technical issues of storage chip spends the time long, low efficiency.
In order to solve the above-mentioned technical problem, one aspect of the present invention provides a kind of EMMC means of storage bulk filling map datum
Method, include the following steps：
1) map datum, is stored in storage unit to be copied；
2), before EMMC storage chip is not built in vehicular amusement apparatus, EMMC storage chip is placed on copying apparatus
On adapter；
3), the map datum in storage unit to be copied is copied in blank EMMC storage chip by copying apparatus.
Preferably, the storage unit to be copied is that computer or EMMC store mother chip.
Based on the method for above-mentioned EMMC means of storage bulk filling map datum, another aspect of the present invention also provides one kind
The equipment of EMMC means of storage bulk filling map datum, if including copying apparatus, computer and dry plate blank EMMC storage core
Piece；The computer is connect with copying apparatus, copies map datum in the copying apparatus female adapter by the computer
EMMC storage chip and sub- adapter on EMMC storage chip on.
Preferably, the copying apparatus is flash memory copying apparatus.
Technical solution provided by the invention copies map datum to EMMC storage chip by copying apparatus, easy to operate,
It is high-efficient, the vehicular map data of large capacity can be once filled on several pieces EMMC chips.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, the present invention will be implemented below
Attached drawing needed in the description of example or the prior art is briefly described.It should be evident that the accompanying drawings in the following description
Only a part of the embodiments of the present invention, for those of ordinary skill in the art, in not making the creative labor property
Under the premise of, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is existing in-vehicle multi-media system host storage inside schematic diagram；
Fig. 2 is a kind of flow diagram of the method for EMMC means of storage bulk filling map datum of the embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The way of OEM vendor is to connect navigation map data by USB after producing finished product vehicle multimedia navigation at present
Mouth is transferred in system in EMMC storage chip, and consuming time is long, low efficiency.
Fig. 2 is referred to, in order to solve the above-mentioned technical problem, the present embodiment provides a kind of EMMC means of storage bulk filling
The method of diagram data, includes the following steps：
1) map datum, is stored in storage unit to be copied；
2), before EMMC storage chip is not built in vehicular amusement apparatus, EMMC storage chip is placed on copying apparatus
On adapter；
Before EMMC storage chip is not built in vehicular amusement apparatus, EMMC storage chip is the EMMC storage core of blank
Piece.
3), the map datum in storage unit to be copied is copied in blank EMMC storage chip by copying apparatus.
Wherein in step 1, storage unit to be copied is that computer or EMMC store mother chip.If storage unit to be copied
For computer, the EMMC storage chip of 1 blank is placed on female adapter of copying apparatus, if placing dry plate on sub- adapter
The EMMC storage chip of blank, by computer by map datum copy to female adapter EMMC storage chip and sub- adapter
On EMMC storage chip on；If storage unit to be copied is the EMMC storage mother chip for storing map datum, EMMC storage
Depositing mother chip can be the chip for prestoring map datum, be also possible to be placed on female adapter through computer copy
EMMC storage chip can not directly be copied using the data of the EMMC storage chip of female adapter in this step by computer
EMMC storage chip on shellfish to sub- adapter, completes the copy of map datum.
Based on the method for above-mentioned EMMC means of storage bulk filling map datum, the present embodiment also provides a kind of EMMC storage
The equipment of the filling map datum of member batch, if including copying apparatus, computer and dry plate blank EMMC storage chip.Wherein copy
Shellfish machine is flash memory copying apparatus.Computer is connect with copying apparatus, copies map datum in copying apparatus female adaptation by computer
In the EMMC storage chip of device and the EMMC storage chip on sub- adapter.
Technical solution provided in this embodiment copies map datum to EMMC storage chip, operation letter by copying apparatus
