Description
Technical Field
The present invention relates to the field of embedded device systems, and in particular, to a system upgrade method and apparatus for an embedded device.
Background
In recent years, embedded wearable products have gradually risen, and embedded equipment products are diversified. Because the system data packet of the embedded device is too large, when upgrading the system version, a binary differential reduction method is generally adopted, and OTA (Over-the-Air Technology) upgrading is performed.
The difference reduction method is that all embedded devices do not bypass a basic function, and the difference reduction method of the OTA in the industry at present basically adopts a uniform binary difference method based on contents to manufacture a difference packet for a resource file and a firmware file of a module chip so as to reduce the current version of the system to a target version.
However, because the computational power of an MCU (Microcontroller Unit) is limited, the time consumed in restoring the differential packet by the binary differential method is long, which affects the speed of upgrading the system version and user experience. Therefore, a system upgrade method is needed to improve the system version upgrade efficiency of the embedded device and reduce the system version upgrade time of the embedded device.

and the embedded equipment upgrades the system file of the embedded equipment from the first system version to the second system version according to the first upgrading part and the second upgrading part.
In the technical scheme, the upgrade difference packet is determined to be different difference parts, and the current version of the system is restored to the target version according to the different upgrade parts, wherein the first upgrade part obtained based on the content difference can avoid overlong restoration time caused by overlarge difference files, and the second upgrade part obtained based on the file difference can avoid overlow restoration efficiency caused by the overlarge required restoration positions of the difference files, so that the system version restoration efficiency is improved, and the system version restoration time is shortened.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, when the OTA upgrade package of the multi-type firmware of the embedded system is differentially restored, the difference is that the OTA upgrade package may include a file differential in units of files and a content differential in units of measurement units (such as KB, MB, etc.) of file contents.
The file difference is equivalent to directly determining a file with two system versions having difference as a difference part, when the system is upgraded, the file is directly used as an upgrading part to be upgraded, and when the difference reduction calculation is carried out, the calculation is carried out by taking the file as a unit so as to reduce the calculation of the difference reduction. For example, a file a in the first system version and a file a in the second system version have some program differences, so that the file a is determined as a differential part, and when the first system version is upgraded to the second system version, the file a is directly used as an upgrade part to replace the file a to upgrade the system version, where only one differential reduction calculation is performed on the file a during the upgrade, and the differential reduction calculation may be reduced, where the file a and the file a are files of the same firmware or files of the same function, generally, names of the two files are the same, and may also be different, and are not limited specifically, and here, "a" and "a" do not refer to file names.
The content difference is equivalent to searching for content difference according to a preset data metering unit for any file, determining the content with difference as a difference part in the preset data metering unit, and replacing data at the position with the content difference instead of replacing the file when the system is upgraded. For example, a preset data measurement unit is set to 100KB for an a-file (200 KB in size) in the first system version and an a-file (210 KB in size) in the second system version, whereby the data of the a-file can be divided into two segments, 0-100KB and 101KB-200KB, and a data header and a data segment data flag for each segment of data are recorded. When the file a is compared with the file A, the file A also determines two sections of data according to the data header and the data segmentation data marks, and compares the two sections of data with the data of the file a one by one, if the difference between the first section of data (0-100KB) in the file a and the first section of data (0-110KB) in the file A is found, the first section of data of the file A is determined as a differential part, when the system version is upgraded, the differential reduction is carried out on the first section of data of the file A, the corresponding upgraded file is obtained, and then the system version is upgraded.
In the two system version upgrading methods, for the system version upgrading of the file difference, if the resource of the file is too large (such as 10MB) and the difference content is smaller (such as 20KB), when the system version upgrading is performed by using the file difference, the resource of the difference part which needs to be subjected to the difference reduction is too large, so that the difference reduction time is too long, and the system version upgrading efficiency is affected.
In the system version upgrading aiming at the content difference, if the resource of a file is smaller (such as 200KB), the difference content is more, and the preset data measurement unit is smaller (such as 10KB), the difference part of the file is too much, and when the system version upgrading is carried out, a differential reduction algorithm needs to be carried out for many times to obtain the corresponding upgrading part, so that the system version upgrading efficiency is low.
Therefore, a method for upgrading a system version is needed to improve the efficiency of upgrading the system version.
Fig. 1 illustrates an exemplary system architecture to which embodiments of the present invention are applicable, which includes a server 100, where the server 100 may include a processor 110, a communication interface 120, and a memory 130.
Wherein the communication interface 120 is used for transmitting the differential part between different system versions.
The processor 110 is a control center of the server 100, connects various parts of the entire server 100 using various interfaces and routes, performs various functions of the server 100 and processes data by operating or executing software programs and/or modules stored in the memory 130 and calling data stored in the memory 130. Alternatively, processor 110 may include one or more processing units.
The memory 130 may be used to store software programs and modules, and the processor 110 executes various functional applications and data processing by operating the software programs and modules stored in the memory 130. The memory 130 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function, and the like; the storage data area may store data created according to a business process, and the like. Further, the memory 130 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
It should be noted that the structure shown in fig. 1 is only an example, and the embodiment of the present invention is not limited thereto.
Based on the above description, fig. 2 exemplarily shows a flowchart of a system upgrade method for an embedded device according to an embodiment of the present invention, where the flowchart may be executed by a system upgrade apparatus for an embedded device.
As shown in fig. 2, the process specifically includes:
In an embodiment of the present invention, the upgrade differential package is determined based on a difference between the first system version and the second system version. The differences include differences of logic codes, differences of parameters set in the logic codes, and the like, and are not limited to specific differences.
In step 220, the embedded device determines a first differential portion and a second differential portion from the upgraded differential packet.
In one implementation, the first differential portion and the second differential portion may both be differentiated according to content.
In another practical way, the first differential part and the second differential part may be obtained according to file differentiation.
In the embodiment of the invention, the first difference part is obtained by content difference, and the second difference part is obtained by file difference.
In the embodiment of the invention, the corresponding differential reduction algorithm is adopted according to the mode of obtaining the differential part, and then the corresponding upgrading part is obtained.
And step 240, the embedded device upgrades the system file of the embedded device from the first system version to the second system version according to the first upgrading part and the second upgrading part.
In step 210, the upgrade difference package is generally configured by a server, and the server determines the upgrade difference package according to a difference between a first system version and a second system version of the embedded device, where the first system version may be understood as a current system version of the embedded device, and the second system version may be understood as a system version with upgrade.
Further, fig. 3 exemplarily shows a flow chart of a method for generating an upgraded differential packet, and as shown in fig. 3, the flow chart includes the following steps.
In step 310, the server determines a first chip file and a first resource file from the files of the first system version of the embedded device.
In the embodiment of the present invention, a server determines a file corresponding to a first system version of an embedded device according to the first system version, and the file of the system version generally includes a chip file and a resource file, and fig. 4 exemplarily shows a schematic diagram of classification and format of a file, and as shown in fig. 4, the file of the system version includes a chip file and a resource file.
Specifically, the chip files are generally binary files, and include files in an stm.bin format, files in an nfc.bin format, files in a tp.bin format, files in a bt.bin format, and the like. The resource file is generally an interface file, and includes a png format (a picture format), a jpg format (a picture format), an xml format (a table format), a js format (a language format), and so on.
In one implementation, the files in the embedded device may be distinguished according to file names.
In the embodiment of the present invention, the files may be distinguished according to the format of the files or according to the resource sizes of the files.
Further, the server determines the first chip file and the first resource file from each file of the first system version according to the format of each file in the first system version of the embedded device, or determines the first chip file and the first resource file from each file of the first system version according to the resource size of each file in the first system version of the embedded device.
For example, a file whose file format is a binary format is determined as a first chip file, such as a file in stm. Determining a file with a file format of png, a file with a jpg format and a file with an xml format as a first resource file.
For another example, a file with a resource size larger than 1MB is determined as the first chip file, and a file with a resource size not larger than 1MB is determined as the first resource file.
In step 320, the server determines a second chip file and a second resource file from the files of the second system version of the embedded device.
In the embodiment of the present invention, the server determines the corresponding second chip file and second resource file according to the manner in step 310. For example, if the server determines the first chip file and the first resource file from the files of the first system version according to the file grid in step 310, the server determines the second chip file and the second resource file from the files of the second system version according to the file format. If the server determines the first chip file and the first resource file from the files of the first system version according to the file format in step 310, the server determines the second chip file and the second resource file from the files of the second system version according to the file format.
In an embodiment of the present invention, the first differential portion is determined by performing content differential according to a first chip file and a second chip file, for example, the first chip file is a binary B-file, the size of the B-file is 1.2M, the B-file is divided into 12 parts of first file contents according to the content differential method, a data header and a data trailer of each part of the first file contents are recorded, then the B-file of the second chip file is divided into 12 parts of second file contents according to the data header and the data trailer of each part of the first file contents, N parts of the file contents having a difference are determined, and corresponding data headers and data trailers are recorded, where N is not greater than 12, so that the first differential portion is obtained according to the N parts of the file having a difference and the corresponding data header and data trailer.
In this embodiment of the present invention, the second difference portion is determined by performing file difference according to the first resource file and the second resource file, for example, on the basis of consistency of file names, it is determined whether the first resource file and the second resource file have a difference, and if there is a difference, the second resource file is determined as the second difference portion.
In an implementation manner, the first differential part and the second differential part may be stored in a folder, and then the folder is compressed, so as to determine the hierarchical differential packet.
In another practical way, the first differential part and the second differential part are compressed respectively to obtain a first compressed file and a second compressed file, and then the first compressed file and the second compressed file are stored in a folder to obtain the upgrade differential packet.
In the embodiment of the invention, the server combines the first difference part and the second difference part according to a preset programming language to determine the upgrade difference packet. The preset programming language may be a merge instruction in an SQL statement, or may be an instruction of another programming language, which is not limited herein.
In the step 220, the embedded device obtains the first upgraded part according to the first restoring algorithm based on the first difference part, where the first restoring algorithm is a content difference-based restoring algorithm.
And the embedded equipment obtains a second upgrading part based on a second difference part according to a second reduction algorithm, wherein the second reduction algorithm is a file difference-based reduction algorithm.
In the embodiment of the invention, aiming at different differential parts, the corresponding upgrading parts, namely upgrading files, can be restored according to the corresponding restoration algorithm.
For example, for the first differential portion, since the first differential portion is obtained by content differentiation, a content differentiation-based restoration algorithm is applied to the first differential portion, so that an upgrade file can be obtained, where the upgrade file includes different locations and contents of chip files, which are equivalent to locations and contents that need to be upgraded.
For the second difference part, because the second difference part is obtained by file difference, a restoration algorithm based on file difference is used for the second difference part, and an upgrade file can be obtained, wherein the upgrade file comprises files which are different from the files of the first version system correspondingly and are equivalent to files needing to be upgraded.
It should be noted that, after the embedded device obtains the upgrade differential packet, before the embedded device determines the first differential part and the second differential part from the upgrade differential packet, the embedded device checks that the upgrade differential packet passes.
In one implementable approach, the upgraded differential packet is checked according to a parity check method.
In another implementation, the upgrade difference packet is checked against a Cyclic Redundancy Check (CRC). The CRC method is a channel coding technology for generating a short fixed bit check code according to data such as network data packets or computer files and the like, and is used for detecting or checking errors which may occur after data transmission or storage by using the principles of division and remainder.
For example, the sender and the receiver may agree on a predetermined integer P before communicating. And then the sender determines F meeting a formula of T mod P ═ 0 according to the data D before sending, generates a CRC code T, and then T is the splicing of the data bit D and the check bit F and sends T to the receiver. And after receiving the CRC code T, the receiving side performs a result-T mod P operation, and if and only if the result is 0, the receiving side determines that the data sent by the sending side is correct.
In the embodiment of the invention, the upgrade difference packet is verified according to an RSA encryption algorithm. The RSA algorithm is an asymmetric encryption algorithm and is also an algorithm of a public key, the key comprises a public key and a private key, and the public key is a public key.
For example, the receiver randomly selects two unequal prime numbers, determines a public key and a private key according to an euler function and a preset random integer, and discloses the public key. When the sender sends the ciphertext, the sender encrypts the ciphertext through the public key and sends the encrypted data to the receiver. And the receiver decrypts the encrypted data according to the private key which is not disclosed by the receiver to obtain the ciphertext.
In the embodiment of the invention, the receiver is equivalent to an embedded device, the sender is equivalent to a server, the ciphertext is equivalent to the upgrade difference packet, and the embedded device verifies the upgrade difference packet after the public key is encrypted according to the private key.
In step 240, the embedded device restores a second system version based on the first system version according to the first updated portion and the second updated portion, and then updates the system file of the embedded device from the first system version to the second system version according to the restored second system version.
In order to better explain the above technical solution, the generation of the upgrade difference packet and the system upgrade of the embedded device are explained in the following specific example.
Example 1
Fig. 5 exemplarily shows a schematic diagram of generation of an upgrade difference package, as shown in fig. 5, a server determines, for a current basic version (equivalent to the first system version) and a target version (equivalent to the second system version) to be upgraded of an embedded device system, files between the two versions, and divides the files into a chip file and a resource file according to a file format or a resource size, determines a chip file difference portion according to the chip file of the basic version and the chip file of the target version, determines a resource file difference portion according to the resource file of the basic version and the resource file of the target version, and then merges the chip file difference portion and the resource file difference portion according to a merge instruction in an SQL statement to obtain the upgrade difference package.
In the embodiment of the invention, the upgrade differential packet is obtained by combining the chip file differential part and the resource file differential part, only one upgrade differential packet can be checked without checking the two differential parts when the safety and the accuracy of the upgrade differential packet are checked, so that the checking cost and the checking time are reduced, the checking efficiency is improved, and the file transmission resource is also saved.
