Under qualitative change more technology contents, when being also considered as the enforceable scope of the present invention.
Referring to Fig. 1, data processing method steps schematic diagram of the invention is shown as, as shown in Figure 1, a kind of data processing
Method, comprising:
S1, upgrading package informatin is obtained, the upgrading data in upgrading package informatin is extracted, in one embodiment, using bsdiff
Catalogue changes the generation that judgement tool carries out difference, for example, in a preset vehicle from vehicle-mounted road by determination in equipment group
In the case that corresponding system version is not highest version, the corresponding system version of preset vehicle can be upgraded to highest version
This；Update the corresponding scalable list of preset vehicle；
S2, the directory information upgraded in data, traversing directories information, to obtain difference analysis as a result, implementing one are extracted
In example, software package is usually made of multiple files, can be packaged into a mirror image, is unfavorable for efficiently generating for difference packet after packing,
Therefore it needs to consider to unpack mirror image before difference, for the file difference one by one of packet the inside, difference is finally pressed into certain rule again
A new packet is then formed, for example, can be using the vehicle (for example, vehicle A) with highest version to one in remaining vehicle
A (for example, vehicle B) is upgraded, latter two right vehicle (vehicle A and vehicle B) again respectively upgrades remaining vehicle, according to
It is secondary to analogize, until all vehicles are upgraded to highest version；
S3, according to difference analysis result to acquisite approachs operation information, generate be packaged description information accordingly, in an embodiment
In, difference generation needs to calculate all father nodes of current version node to the version difference of current version node, terminal device
Such as vehicle system for needing to upgrade etc., it need to be fed back when installing the installation kit that cloud server is sent by network connection really
Information is recognized to cloud, and such as enterprise-level server can be selected in cloud；
S4, according to be packaged description information be packaged upgrading data, to obtain difference packet, in one embodiment, difference generate by
In calculating, the time is long, it may be considered that background task processing, file cannot be confused and encryption, otherwise cannot effectively give birth to
At difference.
Referring to Fig. 2, being shown as step S1 in Fig. 1 is having been carried out the specific steps schematic diagram in example, as shown in Fig. 2, obtaining
Upgrading package informatin is taken, the step S1 of the upgrading data in upgrading package informatin is extracted, comprising:
S11, extract upgrading package informatin in packing unpacked data, in one embodiment, obtain the software it is corresponding be packaged/
Algorithm is unpacked, the old and new's software package is unpacked by packing algorithm, may include such as terminal device example in terminal upgrade daily record data
As the previous all previous upgrading of central control system, control unit and onboard control device such as vehicle system records data；
S12, upgrading primary state data and upgrading final state data are obtained；
S13, primary state data are upgraded according to packing unpacked data processing and upgrade final state data for version correlation data, one
In embodiment, the catalogue and file difference of the old and new's software package are compared from root node；
S14, upgrading data, in one embodiment, interior embedded device three categories type are obtained according to version correlation data
Upgrading mode, such as the corresponding scalable list of preset vehicle may include the information of vehicle for example to be upgraded, vehicle to be upgraded
It is lower than the vehicle of the corresponding system version of preset vehicle by the system version of vehicular applications system in equipment group for vehicle-mounted road.
Referring to Fig. 3, being shown as step S2 in Fig. 1 is having been carried out the specific steps schematic diagram in example, as shown in figure 3, obtaining
Take the step S2 of difference analysis result, comprising:

Each of catalogue and file, if the catalogue or file are not present in old packet, it is meant that be newly-increased file or catalogue
(A), in the present embodiment, catalogue data can be vehicle control syetem such as micro-control unit, unit control unit, full-vehicle control
The upgrade file catalogue data of unit；
S22, update ergodic data acquisition update packet hash is calculated, in one embodiment, if existed in old packet,
And be file, it may include the programming system etc. of for example vehicle-mounted micro-control unit of vehicle-mounted hardware in old packet；
S23, update difference information is obtained according to update packet hash, in one embodiment, if file or catalogue exist
It is not present in new packet, it is meant that it is the file deleted or catalogue (D), if it does, a still catalogue, then recurrence to specific item
Record, for example, starting after Vehicle Controller receives the CAN message that host computer is sent line by line to the institute of CAN message described in buffer records
The data of carrying, until the data receiver of upgrade file is finished；
S24, primary state ergodic data is calculated, obtains primary state differential data, in one embodiment, such as the old and new file hash,
It if existed in old packet, and is catalogue, recurrence to next stage catalogue traverses each of old packet catalogue and file, such as
Upgrade signal order is sent to Vehicle Controller, if Vehicle Controller does not receive in 3S to Vehicle Controller by CAN bus
The upgrade command signal sent to host computer；
S25, data acquisition difference analysis is checked the mark as a result, in one embodiment, such as according to new packet hash and primary state
Fruit hash value is different, then calculates the difference (U) of two files.
Referring to Fig. 4, being shown as step S3 in Fig. 1 is having been carried out the specific steps schematic diagram in example, as shown in figure 4, obtaining
Take the step S3 for being packaged description information, comprising:
S31, difference result is repacked in one embodiment according to difference analysis result acquisition differential path data；
S32, default difference scheme data are obtained, in one embodiment, are packaged format: being packaged description file diff.conf,
Textual form A/U/D filePathl, A/U/D filePath2 ..., if it is A, it is meant that subsequent path is to need newly
It is added in old packet, if it is D, it is meant that subsequent path needs to delete from old packet, if it is U, it is meant that below
Path file be respective file in old packet difference packet；
S33, packing description information, in one embodiment, file are generated according to difference scheme data and differential path data
List File1, File2 ... packing algorithm: are packaged compression to foregoing description file and lists of documents using gzip and form one
The packet of a completion.
