Problems solved by technology

[0002] At present, the intelligentization of food processing machines (such as soybean milk machines) has become a trend. Upgrading food processing machine programs through remote server backgrounds has become an increasingly common function of smart devices. However, since remote upgrades involve local devices, communication modules ( Such as 2G module or WIFI module) and the background server, once the data is abnormal, the program upgrade will fail. Considering that the program storage capacity in the current food processor is small, in general, the original program can only be erased and then written. , the program cannot be backed up, so once the program upgrade fails, the machine will be unusable and cannot be upgraded again through the background

Embodiment 1

[0039] An embodiment of the present invention provides a remote upgrade control method for smart home appliances. The control chip of the smart home appliance includes a storage area, the storage area is less than 100K, and the storage area includes: a BOOT area and a firmware area; the program runs in the firmware area; figure 1 As shown, the method may include S101-S102:

[0040] S101. Before erasing the data in the firmware area to remotely upgrade the firmware area, verify the latest version of the upgrade data received in the BOOT area;

[0041] S102. When the verification result shows that the upgrade data is normal, erase the data in the firmware area, and upgrade the firmware area by using the upgrade data.

[0042] Optionally, the storage area of ​​the smart home appliance may also include: a sign area;

[0043] The method may further include: during the upgrading process of the firmware area, setting an upgrade flag in the flag area, and clearing the upgrade flag in...

Embodiment 2

[0050] On the basis of the first embodiment, this embodiment provides a specific implementation manner of verifying the latest version of the upgrade data received in the BOOT area.

[0051] Optionally, as in figure 2 As shown, verifying the latest version of the upgrade data received in the BOOT area may include S201-S203:

[0052] S201. Perform a pre-upgrade in the BOOT area according to the latest version of the upgrade data;

[0053] S202. After the pre-upgrade is completed, check whether the preset check flag bit is correct;

[0054] S203. Determine that the upgrade data is normal when it is detected that the check flag is correct, and determine that the upgrade data is abnormal when it is detected that the check flag is incorrect.

[0055] In the embodiment of the present invention, after entering the BOOT area, first perform a pre-upgrade with the communication module, that is, when upgrading for the first time, do not erase the data in the firmware area, but only re...

Embodiment 3

[0060] On the basis of the second embodiment, this embodiment provides an embodiment solution in which the machine notifies the communication module to reacquire the latest version data of the server after the pre-upgrade data is abnormal.

[0061] Optionally, the method may further include: when the verification result is that the upgrade data is abnormal, feeding back the verification result to the communication module, and re-downloading the latest version of the upgrade data through the communication module.

[0062] In the embodiment of the present invention, if it is judged that the firmware upgrade is wrong during the pre-upgrade process, the machine can notify the communication module in the BOOT area that the firmware data is abnormal, and the communication module can re-download the latest version data to the server to ensure that the firmware upgrade proceeds smoothly.

[0063] In the embodiment of the present invention, under normal circumstances, the communication ...

Abstract

The embodiment of the invention discloses an intelligent household appliance remote upgrade control method. A control chip of the intelligent household appliances comprises a memory area which is smaller than 100K. The memory area may include a boot area and a firmware area. The program runs in the firmware area. The method comprises the following steps of before the data of the firmware area is erased to perform remote upgrade on the firmware area, checking the latest version of the upgrade data received by the BOOT area; before the data of the firmware area is erased to perform remote upgrade on the firmware area, when the verification result is that the upgraded data is not abnormal, erasing the firmware area data and upating the firmware area through the upgraded data. In accordance with that embodiment, the machine upgrade failure in the event of due to the abnormal or lost data downloaded by a communication module, the machine cannot be used, is avoided, the machine can maintainthe pre-upgrade version and is used normally, and the upgrade can be completed again, thereby improving the security and reliability of the upgrade process, reducing the probability of remote upgradefailure, and improving the user experience.
