It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1b is a flowchart of an application program upgrading method according to an embodiment of the present invention, where the embodiment is applicable to a situation of upgrading at least one application program in a vehicle-mounted device. The method can be executed by the application program upgrading device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware mode and is applied to vehicle-mounted equipment.
Specifically, as shown in fig. 1b, the method for upgrading an application program according to the embodiment of the present invention may include the following steps:
s110, receiving the release information of the upgrade package of the application program pushed by the cloud equipment through a master control controller; the release information at least comprises the name and the version of the upgrade package of the application program.
The release information is used for reminding the vehicle-mounted device to upgrade the application to be upgraded and may include information of an upgrade package corresponding to at least one application program. Accordingly, the application programs are scalable application programs for providing internet-of-vehicles services such as music, video, radio, news, and food in vehicles.
The master controller can be understood as a master controller in the vehicle-mounted equipment, and optionally, the upgrade packages received from other equipment ends can be sent to each controller to be upgraded in the vehicle-mounted equipment through a data transmission channel between the master controller and the controller to be upgraded. Correspondingly, the controller to be upgraded upgrades the application program of at least one application to be upgraded related to the received upgrade package according to the received upgrade package.
In this embodiment, an application developer or manager sends an upgrade package to a server; the server receives the upgrade package, determines and issues the application upgrade package to the cloud device, and the cloud device pushes the issuing information of the upgrade package to the vehicle-mounted device. Correspondingly, the vehicle-mounted equipment receives the release information of the upgrade package of the application program pushed by the cloud equipment through the master controller.
In an optional implementation manner, the release information of the application at least includes identification information of the application upgrade package, that is, a name and a version of the application upgrade package, so that the vehicle-mounted device can search the application upgrade package corresponding to the identification information in the cloud release system according to the identification information of the upgrade package, and download the application upgrade package.
In order to facilitate obtaining the upgrade package of the application program, improve the obtaining efficiency of the upgrade package of the application program, and reduce the operation processing of the user at the same time, in another optional implementation manner of the embodiment of the application, the release information may further include download information of the upgrade package of the application program, so that the vehicle-mounted device directly downloads the upgrade package of the application program based on the download information, and obtains the upgrade package of the application program from the cloud device. Illustratively, the download information may be a download address, and the download address may be presented in the form of a web address or a two-dimensional code.
And S120, downloading an upgrading package of the application program from the cloud equipment through the master controller according to the release information of the application program.
Optionally, in order to improve the upgrading efficiency of the application program, after receiving the release information of the application program, the vehicle-mounted device may automatically identify the release information, and download the application program upgrading package corresponding to the release information according to the release information of the application program. Specifically, the upgrade package of the application program can be downloaded from the cloud device through the master controller.
In order to avoid the influence of the upgrade package downloading process on other using processes of the user, the upgrade package can be downloaded in a mode of manual triggering of the user. And after receiving the triggering operation of the user, downloading the application program upgrading package corresponding to the release information according to the release information of the application program.
The release information includes information of an upgrade package corresponding to at least one application program. If the release information only corresponds to one application program upgrade package, the corresponding application program upgrade package can be downloaded according to the release information, and the downloaded upgrade package is installed. If the release message includes at least two application program upgrade packages, the at least two application program upgrade packages associated with the release message may be downloaded according to the release message, and the downloaded application program upgrade packages may be installed.
When there are at least two application program upgrade packages, in an optional implementation manner, the download operation of each application program upgrade package may be performed in parallel, so as to improve the download efficiency of each application program upgrade package, and further improve the upgrade efficiency of each application program.
In order to further improve the upgrading efficiency of the application program, when at least two application program upgrading packages exist, in another optional embodiment, after the corresponding application program upgrading packages are downloaded and acquired, the installation operation of each application program upgrading package can be performed in parallel.
And S130, verifying the upgrading package of the application program based on the pre-established block chain.
The block chain is pre-established when the server sends the application program upgrading packet, and the block chain stores the on-chain hash value corresponding to each upgrading packet and is used for verifying the upgrading packet.
In order to ensure the stability of subsequent application program upgrading, the vehicle-mounted device may verify the application program upgrading package based on a block chain established in advance in the application program upgrading process.
Specifically, in order to improve the integrity and correctness of transmission of the application program upgrade package and ensure the stability of subsequent application program upgrade, in an optional implementation manner of the embodiment of the present application, after the vehicle-mounted device downloads the application program upgrade package and before the application program upgrade package is installed, a local hash value corresponding to the upgrade package of the application program may be generated according to the upgrade package of the application program; and verifying the local hash value corresponding to the upgrade package of the application program based on the block chain.
In order to facilitate later-stage verification of the local hash value corresponding to the upgrade package of the application program, the vehicle-mounted device may first obtain the on-chain hash value corresponding to the upgrade package of the application program on the block chain, and judge consistency between the on-chain hash value corresponding to the upgrade package of the application program and the local hash value.
On the basis of the above embodiment, in order to accurately obtain the hash value on the link corresponding to the upgrade package of the application program on the block link, the vehicle-mounted device may retrieve the hash value on the link corresponding to the upgrade package of the application program on the block link established in advance according to the name and version of the upgrade package of the application program. Further, if the on-chain hash value corresponding to the upgrade package of the application program is retrieved on the block chain, whether the local hash value is consistent with the on-chain hash value is judged. If the local hash value is consistent with the hash value on the link, judging that the local hash value is verified; and if the local hash value is not consistent with the hash value on the chain, judging that the local hash value is not verified.
In order to improve the efficiency of the hash value on the chain, in an optional embodiment, when the hash value on the chain corresponding to the application program upgrade package is retrieved, the hash value on the chain corresponding to the application program upgrade package may be retrieved according to the name of the upgrade package. And if the retrieval result has a plurality of on-chain hash values corresponding to the upgrade package, retrieving from the preliminary retrieval result according to the version of the upgrade package. The method has the advantages that when only one version exists in a certain name upgrading package, secondary retrieval is not needed, and retrieval efficiency is improved.
In order to ensure the accuracy of hash value retrieval on the chain, in another alternative embodiment, the retrieval may be performed according to the name and version of the application upgrade package at the same time. According to the name and the version of the application program upgrading packet, the hash value on the chain corresponding to the application program upgrading packet can be uniquely determined.
And S140, if the verification is passed, upgrading the application program by using the upgrading package of the application program.
Because the vehicle-mounted equipment downloads the upgrading packet through the master controller, correspondingly, after the verification is passed, the upgrading packet received from other equipment ends is sent to each controller to be upgraded in the vehicle-mounted equipment through a data transmission channel between the master controller and the controller to be upgraded. Correspondingly, the controller to be upgraded upgrades the application program of at least one application to be upgraded related to the received upgrade package according to the received upgrade package.
On the basis of the above embodiment, specifically, after downloading the upgrade package of the application program, the master controller may determine the controller to be upgraded corresponding to the application program according to the name of the upgrade package of the application program; sending a notification message to the controller to be upgraded corresponding to the application program, so that the controller to be upgraded corresponding to the application program responds to the notification message to acquire an upgrade package of the application program in the master control controller; and loading the upgrade package of the application program into the application program through the controller to be upgraded corresponding to the application program, thereby realizing the upgrade of the application installed in the vehicle-mounted equipment.
Optionally, the master controller or other devices associated with the vehicle-mounted device store the application program installed in the controller to be upgraded and the current version of each application ascending sequence; the master control controller can search and match the application programs in the controllers to be upgraded according to the downloaded version information of the upgrading packages of the application programs, so that at least one application to be upgraded in the controllers with the upgrade is determined; transmitting at least one upgrading packet of the application to be upgraded in the master controller to the controller to be upgraded; correspondingly, the controller to be upgraded receives the upgrade package. Specifically, according to the received upgrade package, application upgrade is performed on at least one application to be upgraded in the controller to be upgraded, which is associated with the upgrade package.
On the basis of the technical schemes, in order to realize management and monitoring of the application upgrading condition in the controller to be upgraded, after the controller to be upgraded upgrades the application according to the received upgrading packet, an upgrading receipt can be sent to the master controller; correspondingly, the master controller receives the upgrade receipt sent by the controller to be upgraded, and the upgrade receipt is used for local storage or reporting to other equipment associated with the vehicle-mounted equipment, so that the upgrade receipt is stored in the other equipment. And the upgrade receipt comprises the version and/or the upgrade result of each application to be upgraded related to the received upgrade package. And the upgrading result comprises upgrading success and upgrading failure. Optionally, if the upgrade result is failure, the application program that fails to be upgraded may be re-upgraded within a set time.
According to the technical scheme of the embodiment, the master control controller receives the release information of the upgrade package of the application program pushed by the cloud equipment; the release information at least comprises the name and the version of an upgrade package of the application program; downloading an upgrading package of the application program from the cloud equipment through the master controller according to the release information of the application program; verifying an upgrade package of an application program based on a pre-established blockchain; and if the verification is passed, upgrading the application program by using the upgrading package of the application program. The embodiment of the invention realizes the verification of the upgrading of the application program based on the block chain, verifies the correctness and the integrity of the upgrading package of the application program and improves the safety and the efficiency of the upgrading of the application program.
Example two

Specifically, as shown in fig. 2, the method includes:
s210, sending the upgrade patch of the application program to the cloud device, so that the cloud device pushes the release information of the upgrade patch of the application program to the vehicle-mounted device.
The release information is used for reminding the vehicle-mounted device to upgrade the application program to be upgraded, and may include information of an upgrade package corresponding to at least one application program. Accordingly, the application programs are scalable application programs for providing internet-of-vehicles services such as music, video, radio, news, and food in vehicles.
Before sending the upgrade package of the application program to the cloud device, an application developer or a manager sends the upgrade package of each application program to be upgraded to a server; the server receives and processes the application program upgrade package.
In order to ensure that the version of the released application program upgrade package is the latest version and avoid inconvenience to a user caused by multiple times of upgrading, in an optional implementation manner, the current version of the application to be upgraded can be compared with the historical version before the upgrade package of the application program is released; and acquiring the application program upgrading packet with a higher version as the application program upgrading packet to be upgraded, and performing subsequent issuing operation.
Optionally, when the cloud device pushes the release information of the upgrade package of the application program to the vehicle-mounted device, corresponding release information may be generated for each application program to be upgraded, so that each application program to be upgraded is distinguished, and independent downloading and installation processing of each application program to be upgraded are realized.
In order to reduce user operations and improve the efficiency of upgrading the subsequent applications to be upgraded, optionally, a piece of release information may be generated for each application program to be upgraded, so that the upgrade packages of the application programs to be upgraded are sequentially downloaded and installed according to the release information.
And S220, generating verification information corresponding to the upgrade package of the application program, and uploading the verification information to a pre-established block chain.
The block chain is used for storing the hash value on the chain corresponding to each upgrade package and is used for verifying the upgrade package subsequently.
In order to improve the integrity and correctness of transmission of the application program upgrade package and ensure the stability of subsequent application program upgrade, in an optional implementation manner of the embodiment of the application, when the server sends the upgrade package of the application program to the cloud device, verification information corresponding to the upgrade package of the application program can be generated according to the upgrade package of the application program and uploaded to a pre-established block chain. The block chain is equivalent to a shared database, and the data or information stored in the shared database has the characteristics of unforgeability, whole-course trace, traceability, public transparency, collective maintenance and the like.
The server generates verification information corresponding to the upgrade package of the application program according to the upgrade package of the application program, and uploads the verification information to a block chain established in advance, which may specifically include: generating a hash value on a chain corresponding to the upgrade package of the application program according to the name and the version of the upgrade package; and writing the hash value on the chain corresponding to the upgrading packet of the application program into the block chain, so that the subsequent vehicle-mounted equipment can verify the upgrading packet conveniently.
Since the hash value of the upgrade package is stored in the block chain, by using the non-tamper property of the block chain, anyone can not modify the upgrade package and the corresponding verification information maliciously after the upgrade package is generated and the corresponding hash value is written into the block chain, thereby ensuring the integrity and consistency of the upgrade package.
According to the technical scheme, the upgrading package of the application program is sent to the cloud device, so that the cloud device pushes the issuing information of the upgrading package of the application program to the vehicle-mounted device; and generating verification information corresponding to the upgrade package of the application program, and uploading the verification information to a pre-established block chain. The embodiment of the invention realizes the verification of the upgrading of the application program based on the block chain, verifies the correctness and the integrity of the upgrading package of the application program and improves the safety and the efficiency of the upgrading of the application program.
