The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The application provides a quick upgrade method for an airborne intelligent computing system, which mainly comprises the following steps as shown in fig. 1:
step S1, the client of the carrier and the ground server agree on the upgrade version of the software;
step S2, when an upgrade version exists at the ground server, the client of the carrier sends an encryption key of the client to the ground server, receives a version upgrade request packet, an encryption key ID and a signature algorithm ID sent by the ground server, and performs bidirectional verification;
step S3, after verification is passed, the ground server packs the software version to be upgraded into a mirror image packet and transmits the mirror image packet to the client of the carrier;
and S4, unpacking and upgrading by the client of the carrier.
In some alternative embodiments, the carrier client communicates with the ground server via a wireless connection, one ground server corresponding to each of the plurality of carrier clients.
In the embodiment, the rapid upgrading system divides the equipment into a ground service end and a carrier client end, and the two ends communicate through WIFI/4G/5G to transmit data. The ground server is an update release end of software and is connected with the client of the carrier in a pair of phases; the carrier client is an updated software receiving end and is communicated with the carrier client to acquire upgrade information.
In some optional embodiments, the ground server includes a database layer, a data access layer, and a functional layer, and the carrier client includes a client management layer, an interactive interface layer, and a carrier device layer;
the database layer is used for storing software versions, functional information and carrier information; the data access layer is used for information transmission; the function layer is used for developing the function of the quick upgrade mode, and the client management layer is used for judging the upgrade state of the software, executing the upgrade flow and managing the operation log; the interactive interface layer is used for transmitting and distributing the data packets; the carrier equipment layer is used for upgrading the software.
Referring to fig. 2, in the ground server, a database layer stores software version, function information and carrier information such as model, state, etc.; the data access layer is mainly an identity authentication, information transmission communication interface and the like; the functional layer mainly integrates the development of the fast upgrade mode functions. In the carrier client, a client management layer is mainly responsible for judging the upgrading state of software, executing an upgrading flow and managing an operation log; the interactive interface layer is mainly responsible for transmission and distribution of data packets; the carrier device layer is mainly a hardware device for receiving the software algorithm.
In some alternative embodiments, step S1 comprises: the ground server is periodically polled by the carrier client to acquire the upgrade version information of the software, or the ground server sends an upgrade notification with a specified software version to the carrier client.
In some alternative embodiments, step S4 further comprises: and when the level version upgrade fails, performing rollback upgrade based on the software security version stored in the hard disk.
The method and the device provide functions of appointed software version upgrading, specific software version rollback, automatic detection and updating of the software version and the like, and meet daily software upgrading requirements. The method comprises the steps of designating a software version upgrading mode, packaging a software version to be upgraded into a mirror image package according to a stipulated format, wirelessly transmitting the mirror image package to a carrier client, and unpacking and upgrading the mirror image package to carrier equipment after identity and safety verification. The specific software version rollback mode is to set a software safety version to be put in a storage area in order to ensure the use safety of the software when the upgrade version fails to upgrade, and to rollback upgrade the specific software when the upgrade version fails to upgrade. The automatic detection and update software version mode is that after the onboard client is powered on, the server is polled every one period, and if an update request is received, the latest version software is automatically updated.
By setting the version upgrade request packet, the encryption key ID, the encryption algorithm ID, the signature algorithm ID, the upgrade request, the signature and other upgrade request and response messages, the transmission safety and accuracy are ensured. When upgrading, the ground server sends the version upgrading request packet, the encryption key ID, the signature algorithm ID and the like to the client of the carrier, the client performs identity authentication and decryption, and meanwhile, the client sends the encryption key ID to the ground server for bidirectional identity authentication, and if the authentication passes, information transmission can be performed wirelessly.

And the quick upgrading efficiency is determined by detecting the data receiving time, the data checking time and the software programming time of the client of the carrier.
In this embodiment, the data receiving time reflects the size of the transmission file and the bandwidth of the transmission network, so that the size of the transmission file should be compressed and the transmission bandwidth should be increased as much as possible for rapid transmission as much as possible; the data checking time mainly reflects the time of data encryption and decryption, verification and restoration, so that an optimization algorithm is required to optimize the encryption and decryption flow and the verification and restoration modes as much as possible; the software programming time mainly reflects the efficiency of loading the algorithm mirror image into the memory, and the transmission standard needs to be set to improve the programming efficiency and the memory transmission line performance. According to the ratio of the data receiving time to the receiving time threshold, the ratio of the data checking time to the checking time threshold, the ratio of the software programming time to the programming time threshold, and then the ratio can be used as an evaluation standard of the software upgrading efficiency through weighted calculation.
The method solves the problems of complex updating process, long time consumption and poor maintainability of the software version of the airborne equipment, and realizes the function of rapidly updating the algorithm from the ground end to the carrier end.
The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions easily conceivable by those skilled in the art within the technical scope of the present application should be covered in the scope of the present application.
