Referring to fig. 3, fig. 3 is a flowchart of an OTA upgrading method for an electronic device according to an embodiment of the present application, where the method includes, but is not limited to, the following steps:

s301: and acquiring OTA (over the air) upgrading task information.

The OTA upgrading task information comprises the equipment types, the equipment models and the equipment modules of the electronic equipment, wherein one equipment type corresponds to a plurality of equipment models, and one equipment model corresponds to a plurality of equipment modules. The device model number may include information such as product model, product type, product subtype, batch year, batch week, batch number, serial number, etc.

Specifically, the user can set the device type, the device model and the device module in the OTA upgrade task information through the terminal device, and the terminal device responds to the setting of the user after receiving the OTA upgrade task information input by the user.

For example, the user sets, through the OTA upgrade interface of the electronic device, that the device type of the electronic device is a door lock, the product type of the device type is WFP01, the product type is T0, the product subtype is 13, the batch year is 21, the batch week is 27, the batch number is 1, the serial number is 0042, the module 1 of the device module is a front panel, the current OTA version of the front panel is V1.12.008, the module 2 is a back panel, and the current OTA version of the back panel is V1.12.021.

In some embodiments, the hash value corresponding to the device type, the hash value corresponding to the device model, and the hash value corresponding to the device module of the electronic device are added to determine the first hash value of the OTA file of each of the plurality of device modules.

Specifically, the OTA file refers to firmware of the device module, the first hash value refers to a hash value corresponding to a current OTA file of the device module, and the first hash value is a string of 16-ary character strings. And adding the equipment type and the equipment model in the OTA upgrading task information and the hash value corresponding to the equipment module to obtain a first hash value of the current OTA file of each equipment module.

For example, the device type is that the hash value corresponding to the door lock is d242f00aa3bc98, the hash value corresponding to the device model WFP01T013212710042 is 866b32c6f76cd8, the device module is that the hash value corresponding to the front panel is ca903df852d832, and the hash value obtained after addition is 3e197758a56 bd. Thus, the first hash value of the OTA file of the front panel with device model WFP01 is 3e197758a56 bde.

Specifically, when the current OTA version of the OTA file of the first device module is smaller than the latest OTA version of the first device module, that is, the first hash value of the OTA file of the first device module is smaller than the preset threshold, the current OTA version of the OTA file of the first device module is sequentially derived to a second hash value according to the first hash value of the OTA file of the first device module, where the second hash value is a hash value corresponding to the latest OTA version of the first device module. The specific process of derivation is: deducing the hash value of the next OTA version according to the hash value of the previous OTA version, and successively recurrently calculating the hash value of the latest OTA version.

For example, when the current OTA version of the device module is V0.1.0, the hash value of the OTA version V0.1.0 is the first hash value, according to the above method, it may be determined that the first hash value is 3a0de09cf69bfe eca0d71cbbbb2c9044a2d2, from the first hash value, it may be derived that the hash value of the OTA version V0.2.0 is e5ab531790a81e647f2f88ef9d7e85067b5ece b f, from the hash value of the OTA version V0.2.0, it may be derived that the hash value of the OTA version v0.3.0 is 7f48625dbe ac92fa97351ce219e8 cf 40c 40cf50a70, and by recursion, it may be derived that the second hash value of the OTA file is 8798925dce ac92fa97351ce219 a8 c2003a6339 c 58595 2c, that is the latest version of the device module corresponding hash value of the OTA 638 a 63503 a 638 a 639 c503 c 639 c 595 56 c 503.

In the embodiment of the application, the hash values of the latest OTA versions of the OTA files of the equipment modules can be sequentially calculated through the rule no matter what the hash values of the current OTA versions of the OTA files of the equipment modules in the electronic equipment are.

S304: and performing OTA upgrade on the first equipment module based on the second hash value of the OTA file of the first equipment module.

Generally, the upgrading priorities of a plurality of equipment modules may be the same or different, and the modules are upgraded according to the upgrading priority of each equipment module; the upgrading range is the range of OTA versions which can be upgraded by the equipment module, the range of the OTA versions comprises all OTA versions between the current OTA version of the OTA file and the latest OTA version of the OTA file, the equipment module is upgraded according to a certain OTA version selected by a user, and the upgraded OTA version is the certain OTA version selected by the user; the OTA dependent version module refers to an equipment module with the lowest dependent version relationship, for example, the front panel and the rear panel of the door lock are OTA dependent version modules, that is, the OTA version of the OTA file of the front panel is upgraded to the OTA version one, the OTA version of the OTA file of the rear panel is not lower than the OTA version two, the OTA version one is a certain version of the OTA file of the front panel, and the OTA version two is a certain version of the OTA file of the rear panel.

For example, the configuration information of the OTA upgrade task includes device module 1, device module 2, device module 3, and device module 4. The upgrade priority of the device module 1 is a, the upgrade priority of the device module 2 is a, the upgrade priority of the device module 3 is b, and the upgrade priority of the device module 4 is d. When the four equipment modules are upgraded through OTA, firstly, the equipment module 1 and the equipment module 2 are upgraded simultaneously, secondly, the equipment module 3 is upgraded, and finally, the equipment module 4 is upgraded.

Device module 1 is upgraded V0.12.2 to V0.12.6 if the OTA file of device module 1 is set to V0.12.6, and device module 1 is upgraded V0.12.2 to V0.12.7 if the OTA file of device module 1 is set to V0.12.7.

For another example, device module 1 and device module 2 are OTA dependent version modules, the current OTA version of the OTA file of device module 1 is V0.15.1, device module 1 needs to be upgraded to V0.15.9, the current version of the OTA file of device module 2 is V0.2.1, if the condition of device module 1 being upgraded to V0.15.9 is that the version of the OTA file of device module 2 is not lower than V0.2.8, then the OTA version of the OTA file of device module 2 needs to be upgraded to V0.2.8 first, and then the OTA version of the OTA file of device module 1 needs to be upgraded to V0.15.9.

In some embodiments, after OTA upgrade of the first device module, further comprising:

Specifically, the OTA upgrade result includes upgrade success and upgrade failure. After the OTA upgrading is carried out on the equipment module, the electronic equipment sends an OTA upgrading result to the terminal equipment, and the terminal equipment receives the OTA upgrading result.
