Embodiment 1

[0028] The OTA upgrade method applicable to POS machines described in this embodiment is specifically:

[0029] Step 1: After the differential upgrade package is produced by the POS manufacturer, it must be uploaded to the OTA server first. The production tool of the differential package is provided by Google, which consists of some script programs and production tools, and is in the code source code. Differential packages can be generated by controlling compilation conditions and commands.

[0030] Step 2: The server can push it directly to the user, and the user will download the upgrade after receiving the prompt. The user can also check online whether an upgrade is required, and the server will compare the user version number with the latest version number on the server.

Abstract

The invention discloses an OTA upgrade method suitable for POS machines, and relates to the technical field of the Internet. The method includes: the POS machine sends a request to download the differential upgrade package of the installed system; the OTA server receives the request, and obtains a differential upgrade package that matches the installation system carried in the request; at the same time, upgrades the differential The package is sent to the POS machine; after the POS machine downloads the differential upgrade package, restart the POS machine to upgrade, and when the LOGO on the main interface of the POS machine is seen, the upgrade is completed. The OTA upgrade method of the present invention saves storage space and resources; the OTA upgrade method seamlessly upgrades, does not erase data, does not damage the original system in the POS machine, and has no impact on the use of the POS machine; the OTA upgrade method of the present invention will not Due to the unexpected termination of the upgrade, it is necessary to re-upgrade.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an OTA upgrade method suitable for POS machines. Background technique [0002] With the rapid development of intelligent AI, the development of POS machines is bound to be diversified.
