Embodiment 1

[0027] FOTA (Firmware Over-The-Air) is an over-the-air software upgrade technology for mobile terminals. In addition to smart terminal devices with networking capabilities, some general-purpose electronic devices such as smart locks do not need to be specially configured for firmware upgrades. Wifi module, and setting the Wifi module consumes a lot of power, which is not suitable for assembly on this kind of small electronic device. However, such electronic devices also have firmware upgrade requirements, but due to conditions, they basically cannot use FOTA upgrades. At present, this type of electronic equipment is either upgraded by wire, and the after-sales personnel of the manufacturer go to the equipment user's use site to import the firmware upgrade file into the system for upgrade, or use a wireless communication module with poor communication reliability to upgrade, which will bring great harm to the upgrade. Various inconveniences.

Abstract

The invention discloses an FOTA controller. The FOTA controller comprises a Wifi module; a radio frequency communication module; and a single-chip microcomputer which is configured to obtain a firmware upgrade package from a server through the Wifi module, perform protocol conversion on the firmware upgrade package and then send the firmware upgrade package through the radio frequency communication module. The FOTA controller is provided with a plurality of wireless communication modules, gives full scope to the advantages of each wireless communication module, downloads the firmware upgrade package from the server through the Wifi module, then sends the firmware upgrade package to an electronic product to be upgraded through the radio frequency communication module; therefore, the electronic product only needs to be assembled with the same radio frequency communication module, the firmware upgrade package is directly downloaded from the server without assembling a Wifi module, a series of problems of high power consumption and high cost of the Wifi module can be avoided, and the problem of low reliability of other wireless communication modes is avoided. The FOTA controller can beused as a gateway, can be matched with various electronic products at the same time, can be used for upgrading the various electronic products, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of network control, in particular to a FOTA controller. Background technique [0002] At present, there are two ways to upgrade the firmware of electronic products. One way is to upgrade through a reserved hardware interface, and the cost of this solution is too high. Another way to upgrade is through the network upgrade, FOTA (Firmware Over-The-Air) mobile terminal software upgrade over the air, refers to the cloud upgrade technology for devices with networking functions: such as mobile phones, tablet computers, portable media players Provide firmware upgrade services for devices, mobile Internet devices, etc. Users use the network to obtain smart terminal system upgrade packages in an on-demand and easy-to-expand manner, and perform cloud upgrades through FOTA to complete system repair and optimization. [0003] The wireless transmission technology selected when the existing electronic products adopt the ...
