Problems solved by technology

[0003] In the existing technology, the solution usually adopted by home appliances is to directly download the firmware through the network to overwrite and upgrade the original firmware, but this method needs to delete the original firmware before overwriting, once the home appliance is upgraded due to a new firmware version or content error If it fails, you need to contact after-sales professionals to repair it, which will bring a lot of inconvenience to users
Therefore, an improved solution has emerged. By dividing two storage areas in the Flash of smart home appliances, they are used to store the existing running firmware and the downloaded upgrade firmware, so as to directly switch to store the upgrade firmware after the upgrade is successful. However, it will cause the cost of Flash to increase due to the increase in capacity requirements. What is more serious is that if there is a problem with the downloaded upgrade firmware, it will still not be able to achieve a smooth upgrade.

Embodiment 1

[0056] A firmware upgrade method for smart home appliances, such as figure 1 , figure 2 shown, including:

[0057] Receiving response information from the server, wherein the response information includes a download address of an upgrade firmware packet, and the upgrade firmware packet includes a plurality of subpackets and first check information corresponding to each subpacket;

[0058] Obtaining the sub-packets respectively and verifying their first verification information;

[0059] When all the sub-packages are verified successfully, the upgrade firmware data package is downloaded for upgrading.

[0060] Specifically, after receiving the request information for upgrading the firmware of the smart home appliance, the server feeds back a response including the download address of the firmware update package to the smart home appliance according to the request information and the upgrade firmware data package information stored on the server. information, wherein the fir...

Embodiment 2

[0113] Another object of the present invention is to provide a firmware upgrade system for smart home appliances, the firmware upgrade system for smart home appliances includes:

[0114] The server is configured to store an upgrade firmware data package and respond to a firmware upgrade request of a smart home appliance, wherein the upgrade firmware data package includes a plurality of sub-data packages and first verification information corresponding to each sub-data package;

Abstract

The invention relates to a firmware upgrading method for intelligent household appliances. The firmware upgrading method includes the steps that response information of a server is received, wherein the response information comprises downloading addresses of upgrading firmware data packages, and the upgrading firmware data packages comprise a plurality of sub-data packages and first checking information corresponding to every sub-data package; the sub-data packages are obtained respectively, and the first checking information of the sub-data packages is checked; when all the sub-data packagesare successfully checked, the upgrading firmware data packages are downloaded and upgraded. In addition, the invention provides a firmware upgrading system for the intelligent household appliances. According to the firmware upgrading method and system for the intelligent household appliances in the technical scheme, the upgrading firmware data packages are downloaded and checked in batches, the upgrading firmware data packages are fully downloaded and programmed after new firmware data packages are successfully checked, the requirement of the capacity of a running Flash in the checking processis small, the accuracy of the whole upgrading firmware data packages is also guaranteed, and the upgrading process is guaranteed to be capable of being successfully conducted.

Description

technical field [0001] The invention relates to the field of smart home appliances, in particular to a firmware upgrade method for smart home appliances. Background technique [0002] With the continuous development of technology and people's needs for a better life, home appliances have become more and more intelligent. For various smart home appliances, software updates and upgrades are usually required to fix bugs in the old version of firmware, increase New features and UI changes, etc., to provide users with a better experience. [0003] In the existing technology, the solution usually adopted by home appliances is to directly download the firmware through the network to overwrite and upgrade the original firmware, but this method needs to delete the original firmware before overwriting, once the home appliance is upgraded due to a new firmware version or content error If it fails, you need to contact after-sales professionals to repair it, which will bring a lot of in...
