Fig. 1 is a schematic structural diagram of a system for recovering an internet of things terminal firmware according to an embodiment of the present invention. Referring to fig. 1, a system 1 for recovering the terminal firmware of the internet of things includes an internet of things terminal 10 and an internet of things server 12. Only one internet of things terminal 10 is shown in fig. 1, and in practice, a plurality of internet of things terminals 10 may be included in the system 1. The internet of things terminal 10 comprises a POS machine and the like. The components of the system 1 are described in detail below.
The internet of things terminal 10 includes a boot program 10A, firmware 10B, backup firmware 10C, and a terminal storage module 10D. The backup firmware 10C has a first internet of things communication module 100C and a first internet communication module 102C, and the backup firmware 10C has an internet of things communication function and an internet communication function. The terminal storage module 10D is configured to store a terminal serial number 100D and a firmware version number 102D, each internet of things terminal 10 has a unique terminal serial number 100D, and the firmware version number 102D is a version number corresponding to a current firmware. The boot program 10A operates after the internet of things terminal 10 is powered on and started, and the boot program 10A first detects whether the firmware 10B is abnormal. In the present embodiment, the boot program 10A detects whether the firmware 10B is abnormal by detecting the integrity of the firmware 10B.
The boot program 10A runs the backup firmware 10C when the firmware 10B is abnormal. In this embodiment, the boot program 10A copies the backup firmware 10C to a location corresponding to the firmware 10B when the firmware 10B is abnormal, and then runs the backup firmware 10C.

The processing module 12C correspondingly binds a firmware download task according to the terminal serial number 100D and the firmware version number 102D of the firmware abnormality, and correspondingly pushes an upgrade task message through the second internet-of-things communication module 12A. The processing module 12C may also correspondingly bind the download task of the firmware of the latest version and correspondingly push an upgrade task message when the firmware version number 102D is lower than the firmware version number of the firmware upgrade package stored in the upgrade package memory 12D for the internet of things terminal 10. In this embodiment, the second internet communication module 12A implements internet of things communication based on MQTT protocol, and the second internet communication module 12B implements internet of things communication based on HTTP/HTTPs protocol; the first internet-of-things communication module 100C and the second internet-of-things communication module 12A are both connected to an internet of things (not shown) and communicate with each other through the internet of things; the first internet communication module 102C and the second internet communication module 12B are connected to an internet (not shown) and communicate with each other through the internet.
The backup firmware 10C receives the upgrade task message through the first internet of things communication module 100C, and downloads the corresponding firmware upgrade packages 121D, …, 12nD from the internet of things server 12 through the first internet communication module 102C by using the upgrade task message. The backup firmware 10C also determines whether the downloading of the firmware upgrade package is successful, if not, the downloading is continued until the downloading is successful, and if so, the boot program 10A installs the firmware upgrade package at the corresponding position of the firmware 10B.
The upgrade task message includes upgrade package information, and the backup firmware 10C determines whether the downloading of the firmware upgrade package is successful by checking whether the downloaded firmware upgrade package is complete using the upgrade package information, and continues to download the corresponding firmware upgrade package from the internet of things server 12 when it is incomplete (i.e., downloading is unsuccessful) until the complete firmware upgrade package is downloaded (i.e., downloading is successful). The backup firmware 10C checks the integrity of the upgrade package before installing it, ensuring the integrity and validity of the upgrade.
The backup firmware 10C sends a request for downloading a corresponding firmware upgrade package to the internet of things server 12 through the first internet communication module 102C, and the internet of things server 12 receives the request through the second internet communication module 12B and sends the firmware upgrade package to the internet of things terminal 10. The backup firmware 10C supports breakpoint resume when downloading the corresponding upgrade package from the internet of things server 12.
When the firmware upgrade package is installed, the internet of things terminal 10 may issue the upgraded information to the internet of things server 12 through the first internet of things communication module 102C or other similar internet of things communication modules. For example, the bootstrap program 10A may issue the upgrade completed information to the internet of things server 12 through a similar internet of things communication module therein.
