Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] According to one aspect of an embodiment of the present application, a method for upgrading smart home appliances is provided. The method for upgrading smart home appliances is widely used in smart home (Smart Home), smart home, smart home equipment ecology, smart residential (Intelligence House) ecology and other whole-house intelligent digital control application scenarios. Optionally, in this embodiment, the above-mentioned method for upgrading smart home appliances can be applied to Figure 1 In the hardware environment composed of smart home appliances 102 and Internet of Things platform 104 shown in FIG. Figure 1As shown, the Internet of Things platform 104 is connected to the smart home appliance 102 through the network, and can be used to provide services (such as application services, etc.) for the smart home appliances or clients installed on the smart home appliances. A database can be set up on the server of the Internet of Things platform or independently of the server to provide data storage services for the Internet of Things platform 104. Cloud computing and / or edge computing services can be configured on the server of the Internet of Things platform or independently of the server to provide data computing services for the Internet of Things platform 104.

[0036] The network may include but is not limited to at least one of the following: wired network, wireless network. The wired network may include but is not limited to at least one of the following: wide area network, metropolitan area network, local area network, and the wireless network may include but is not limited to at least one of the following: WiFi, Bluetooth. The smart home appliance 102 may be but is not limited to a PC, a mobile phone, a tablet computer, a smart air conditioner, a smart range hood, a smart refrigerator, a smart oven, a smart stove, a smart washing machine, a smart water heater, a smart washing equipment, a smart dishwasher, a smart projection equipment, a smart TV, a smart clothes drying rack, a smart curtain, a smart audio and video, a smart socket, a smart speaker, a smart speaker, a smart fresh air equipment, a smart kitchen and bathroom equipment, a smart bathroom equipment, a smart sweeping robot, a smart window cleaning robot, a smart mopping robot, a smart air purification equipment, a smart steamer, a smart microwave oven, a smart kitchen treasure, a smart purifier, a smart water dispenser, a smart door lock, etc.

[0037] The smart home appliance 102 includes a home appliance baseboard and a WiFi module. The WiFi module includes an OTA (Over-The-Air Technology) partition.

[0038] Combination Figure 2 As shown, the embodiment of the present disclosure provides an upgrade method for a smart home appliance, comprising:

[0039] S01, the WiFi module receives and analyzes the upgrade instruction sent by the IoT platform to obtain the critical capacity value and the upgrade package capacity, wherein the critical capacity value is associated with the storage capacity of the OTA partition.

[0040] In this step, the upgrade instruction includes a critical capacity value. The critical capacity value represents the upper capacity threshold of the entire package download upgrade package. It should be noted that the critical capacity value is less than the storage capacity of the OTA partition. As an example, the storage capacity of the OTA partition is 1964K, and the critical capacity value is 1536K.

[0041] S02, the WiFi module determines a target upgrade strategy according to the critical capacity value and the upgrade package capacity.

[0042] S03, the WiFi module sends a download request to the IoT platform according to the target upgrade strategy and downloads the upgrade package.

[0043] Using the upgrade method for smart home appliances provided by the embodiment of the present disclosure, the WiFi module receives and parses the upgrade instruction sent by the Internet of Things platform, obtains the critical capacity value and the upgrade package capacity, and then determines the corresponding target upgrade strategy based on the critical capacity value and the upgrade package capacity. Finally, a download request is sent to the Internet of Things platform and the upgrade package is downloaded according to the target upgrade strategy. The embodiment of the present disclosure can execute different upgrade strategies according to the size of the critical capacity value associated with the upgrade package capacity and the OTA partition storage capacity. When the upgrade package capacity is large, the smart home appliance system can also be upgraded according to the corresponding upgrade strategy, thereby realizing the system upgrade of smart home appliances in a way that does not increase the hardware cost of smart home appliances.

[0044] Optionally, the WiFi module determines a target upgrade strategy according to the critical capacity value and the upgrade package capacity, including:

[0045] When the critical capacity value is less than the upgrade package capacity, the WiFi module determines the target upgrade strategy as the packet download mode. Or,

[0046] When the critical capacity value is greater than or equal to the upgrade package capacity, the WiFi module determines the target upgrade strategy as the whole package download mode.

[0047] In this way, when the critical capacity value is less than the capacity of the upgrade package, it indicates that the capacity of the upgrade package is higher than the upper capacity threshold of the whole package download upgrade package, and the whole package download upgrade cannot be achieved. At this time, the sub-package download mode is adopted. When the critical capacity value is greater than or equal to the upgrade package capacity, it indicates that the upgrade package capacity is not higher than the upper capacity threshold of the whole package download upgrade package. At this time, the whole package download mode can be adopted. In this way, the embodiment of the present disclosure can determine the corresponding target upgrade strategy based on the size relationship between the critical capacity value and the upgrade package capacity, so that the smart home appliances can realize the system upgrade of the smart home appliances in a way that does not increase the hardware cost, thereby reducing the hardware cost of the smart home appliance upgrade.

[0048] It should be noted that the whole package download mode includes: the WiFi module sends a download request to the IoT platform; after receiving the download request, the IoT platform sends an upgrade package to the WiFi module. As an example, the IoT platform sends the upgrade package to the WiFi module, which can be: the IoT platform sends frame data corresponding to the data frame size corresponding to the upgrade package to the WiFi module in sequence until the upgrade package is sent.

[0049] Optionally, combined Figure 3 As shown in FIG. 1 , when the critical capacity value is less than the upgrade package capacity, the WiFi module sends a download request to the IoT platform according to the target upgrade strategy and downloads the upgrade package, including:

[0050] S11, the WiFi module determines the sub-packet capacity of each upgrade sub-packet as a critical capacity value.

[0051] S12, the WiFi module determines the number of subpacketization times according to the ratio of the upgrade package capacity to the critical capacity value.

[0052] In this step, the WiFi module determines the number of subpackaging according to the ratio of the upgrade package capacity to the critical capacity value, including: the WiFi module obtains the quotient and remainder of the upgrade package capacity and the critical capacity value; when the remainder is zero, the WiFi module determines the number of subpackaging as the quotient; when the remainder is a non-zero value, the WiFi module determines the number of subpackaging as the sum of the quotient and the value 1.

[0053] S13, the WiFi module sends a download request to the Internet of Things platform in sequence according to the subpacket capacity and subpacket number of each upgrade subpacket, and downloads each upgrade subpacket.

[0054] In this way, when the critical capacity value is less than the capacity of the upgrade package, the sub-package download mode is adopted. Specifically, since the critical capacity value represents the upper limit threshold of the capacity of the whole package downloading the upgrade package, in order to minimize the number of sub-packages, the embodiment of the present disclosure determines the sub-package capacity of each upgrade sub-package as the critical capacity value, and at the same time, determines the number of sub-packages according to the ratio of the upgrade package capacity to the critical capacity value. After determining the sub-package capacity and the number of sub-packages, the embodiment of the present disclosure sends a download request to the Internet of Things platform in sequence according to the sub-package capacity and the number of sub-packages of each upgrade package, and downloads each upgrade sub-package. As a result, the embodiment of the present disclosure can realize the sub-package download of the system upgrade package of the smart home appliance by splitting the upgrade package according to the upgrade package capacity and the upper limit threshold of the capacity of the whole package downloading the upgrade package, so that the smart home appliance can realize the system upgrade of the smart home appliance in a way that does not increase the hardware cost.

[0055] Optionally, combined Figure 4 As shown, the WiFi module sends download requests to the IoT platform in turn according to the subpacket capacity and subpacket times of each upgrade subpacket and downloads each upgrade subpacket, including:

[0056] S21, the WiFi module determines the sub-package sequence number i of each upgrade sub-package, wherein the initial value of i is 1.

[0057] S22, the WiFi module sends a download request to the IoT platform, requesting to download the i-th upgrade sub-package.

[0058] S23, when the i-th upgrade sub-package is downloaded, the WiFi module determines the size of the sub-package sequence number i and the number of sub-packages.

[0059] S24, when the sub-package number i is less than the number of sub-packages, the WiFi module updates the sub-package number to i+1, and returns to execute sending a download request and requesting to download the i+1th upgrade sub-package.

[0060] S25, when the sub-packet number i is equal to the number of sub-packet times, the WiFi module determines that the download of the upgrade package is complete.

[0061] In this way, the embodiment of the present disclosure first determines the subpackage sequence number i of each upgrade subpackage, and then sends a download request to the Internet of Things platform, requesting to download the i-th upgrade subpackage. When the i-th upgrade subpackage is downloaded, the size of the subpackage sequence number i and the number of subpackages is determined. If the subpackage sequence number i is less than the number of subpackages, it indicates that the upgrade package has not been fully downloaded. At this time, the subpackage sequence number is updated to i+1 and returns to execute the sending of the download request and request to download the i+1-th upgrade subpackage. If the subpackage sequence number i is equal to the number of subpackages, it indicates that the upgrade package has been fully downloaded and the download of the upgrade package ends. As a result, the WiFi module can split the upgrade package to implement the subpackage download mode, so that the smart home appliances can realize the system upgrade of smart home appliances without increasing the hardware cost.

[0062] Combination Figure 5 As shown, the embodiment of the present disclosure also provides an upgrade method for smart home appliances, including:

[0063] S31, the WiFi module receives and analyzes the upgrade instruction sent by the IoT platform, and obtains the critical capacity value and the upgrade package capacity, wherein the critical capacity value is associated with the storage capacity of the OTA partition.

[0064] S32, the WiFi module determines a target upgrade strategy according to the critical capacity value and the upgrade package capacity.

[0065] S33, the WiFi module sends a download request to the IoT platform according to the target upgrade strategy and downloads the upgrade package.

[0066] S34, the WiFi module sends a download request to the IoT platform according to the target upgrade strategy and downloads the upgrade package, and then sends an upgrade request to the home appliance baseboard.

[0067] S35, when receiving the upgrade confirmation response, the WiFi module sends an upgrade package to the home appliance baseboard, so that the home appliance baseboard upgrades the baseboard according to the upgrade package. The upgrade confirmation response is generated by the home appliance baseboard when receiving the upgrade request.

[0068] Using the upgrade method for smart home appliances provided by the embodiment of the present disclosure, the WiFi module receives and parses the upgrade instruction sent by the Internet of Things platform, obtains the critical capacity value and the capacity of the upgrade package, and then determines the corresponding target upgrade strategy based on the critical capacity value and the capacity of the upgrade package. Finally, a download request is sent to the Internet of Things platform and the upgrade package is downloaded according to the target upgrade strategy. After the WiFi module downloads the upgrade package, an upgrade request is sent to the home appliance baseboard to confirm with the home appliance baseboard whether it has an upgrade requirement. If an upgrade confirmation response is received, it is confirmed that the home appliance baseboard has an upgrade requirement. At this time, the WiFi module sends an upgrade package to the home appliance baseboard so that the home appliance baseboard upgrades the baseboard according to the upgrade package. The embodiment of the present disclosure can execute different upgrade strategies according to the size of the critical capacity value associated with the upgrade package capacity and the OTA partition storage capacity, and notify the home appliance baseboard to upgrade by generating an upgrade request. The embodiment of the present disclosure can realize the system upgrade of smart home appliances in a way that does not increase the hardware cost of smart home appliances.

[0069] Combination Figure 6 As shown, the embodiment of the present disclosure also provides an upgrade method for smart home appliances, including:

[0070] S41, the IoT platform sends an upgrade instruction to the WiFi module to trigger the WiFi module to download the upgrade package.

[0071] S42, the IoT platform receives the download request sent by the WiFi module, and sends the upgrade package to the WiFi module so that the WiFi module downloads the upgrade package according to the target upgrade strategy.

[0072] The download request is generated and sent by the WiFi module after receiving the upgrade instruction according to the critical capacity value and determining the target upgrade strategy.

[0073] Using the upgrade method for smart home appliances provided by the embodiment of the present disclosure, the Internet of Things platform sends an upgrade instruction to the WiFi module to trigger the WiFi module to download the upgrade package, and after receiving the download request sent by the WiFi module, sends the upgrade package to the WiFi module so that it downloads the upgrade package according to the target upgrade strategy. The embodiment of the present disclosure can execute different upgrade strategies according to the size of the critical capacity value associated with the upgrade package capacity and the OTA partition storage capacity. When the upgrade package capacity is large, the smart home appliance system can also be upgraded according to the corresponding upgrade strategy, thereby realizing the system upgrade of the smart home appliance in a way that does not increase the hardware cost of the smart home appliance.

[0074] Optionally, when the critical capacity value is less than the upgrade package capacity, receiving a download request sent by the WiFi module, and the IoT platform sending the upgrade package to the WiFi module so that the WiFi module downloads the upgrade package according to the target upgrade strategy, includes:

[0075] The IoT platform determines the subpackage capacity of each upgraded subpackage as the critical capacity value.

[0076] The IoT platform determines the number of subpackaging times based on the ratio of the upgrade package capacity to the critical capacity value.

[0077] The IoT platform receives the download request sent by the WiFi module and sends the i-th upgrade sub-package.

[0078] When the sub-package number i is less than the sub-package count, the IoT platform receives the download request sent by the WiFi module again and sends the i+1th upgrade sub-package. Where i represents the sub-package number of the upgrade sub-package. When the sub-package number i is less than the sub-package count, the WiFi module updates the sub-package number i to i+1, and returns to execute the download request to request the i+1th upgrade sub-package.

[0079] In this way, when the critical capacity value is less than the capacity of the upgrade package, the sub-package download mode is adopted. Specifically, since the critical capacity value represents the upper capacity threshold of the whole package download upgrade package, in order to minimize the number of sub-packages, the embodiment of the present disclosure determines the sub-package capacity of each upgrade sub-package as the critical capacity value, and at the same time, determines the number of sub-packages according to the ratio of the upgrade package capacity to the critical capacity value. After determining the sub-package capacity and the number of sub-packages, the Internet of Things platform receives the download request sent by the WiFi module and sends the i-th upgrade sub-package. If the sub-package sequence number i is less than the number of sub-packages, the Internet of Things platform receives the download request sent by the WiFi module again and sends the i+1-th upgrade sub-package. Thus, the Internet of Things platform can assist the WiFi module in realizing the sub-package download of the system upgrade package of the smart home appliance by splitting the upgrade package, so that the smart home appliance can realize the system upgrade of the smart home appliance in a way that does not increase the hardware cost.

[0080] It should be noted that, when the critical capacity value is less than the upgrade package capacity, the IoT platform receives a download request sent by the WiFi module and sends the upgrade package to the WiFi module so that the WiFi module downloads the upgrade package according to the target upgrade strategy. It also includes: when the sub-packet number i is equal to the number of sub-packetization times, the IoT platform confirms that the upgrade package download is complete.

[0081] Optionally, the method for upgrading the smart home appliance further includes:

[0082] The WiFi module receives and parses the upgrade command sent by the IoT platform, obtains the critical capacity value and the upgrade package capacity, and then sends an upgrade query request to the home appliance baseboard. The upgrade query request is used to determine whether the home appliance baseboard has the upgrade capability.

[0083] The WiFi module receives the upgrade query response sent by the home appliance baseboard, and the upgrade query response is used to indicate whether the home appliance baseboard has the upgrade capability.

[0084] When the upgrade response indicates that the upgrade capability is available, the WiFi module sends a version query request to the home appliance baseboard to query the version information.

[0085] The WiFi module receives the version information sent by the home appliance baseboard and sends it to the IoT platform so that the IoT platform can determine the upgrade package corresponding to the version information according to the version information. The version information is generated by the home appliance baseboard after receiving the version query request.

[0086] When the upgrade response indicates that the upgrade capability is not available, the WiFi module does not perform the operation.

[0087] In this way, the WiFi module can learn whether the home appliance baseboard has the upgrade capability by exchanging information with the home appliance baseboard, and after determining that it has the upgrade capability, it queries the version information of the home appliance baseboard and synchronizes the version information to the Internet of Things platform so that the Internet of Things platform can determine the upgrade package corresponding to the version information, thereby meeting the upgrade requirements of the home appliance baseboard.

[0088] Optionally, before the IoT platform sends an upgrade instruction to the WiFi module to trigger the WiFi module to download the upgrade package, the process further includes:

[0089] The IoT platform receives the version information sent by the WiFi module.

[0090] The IoT platform determines the upgrade package corresponding to the version information based on the version information.

[0091] It should be noted that after the IoT platform determines the upgrade package corresponding to the version information according to the version information, it also includes: the IoT platform sends a notification message to the user, and the notification message is used to confirm whether to upgrade the upgrade package corresponding to the version information. In the case of receiving the upgrade confirmation message from the user, the IoT platform generates an upgrade instruction. Among them, the upgrade confirmation message is generated when the user confirms the upgrade after receiving the notification message.

[0092] In this way, after receiving the version information and determining the corresponding upgrade package, the IoT platform sends a notification message to the user to ask him or her to confirm whether to upgrade the home appliance baseboard, so that the upgrade operation of the home appliance baseboard meets the user's needs.

[0093] In practical applications, combined with Figure 7 As shown, the upgrade method for smart home appliances specifically performs the following steps:

[0094] S100: The WiFi module sends an upgrade query request to the home appliance baseboard.

[0095] S101: After receiving the upgrade query request, the home appliance base plate sends an upgrade query response to the WiFi module, and the upgrade query indicates that the home appliance base plate has the upgrade capability.

[0096] S102: The WiFi module sends a version query request to the home appliance baseboard to query version information.

[0097] S103: After receiving the version query request, the home appliance baseboard generates version information and sends it to the WiFi module.

[0098] S104, the WiFi module receives the version information and sends it to the IoT platform.

[0099] S105, the IoT platform receives the version information and determines the corresponding upgrade package according to the version information.

[0100] S106, the IoT platform sends a notification message to the user.

[0101] S107, after receiving the notification message, the user sends a confirmation message to the Internet of Things platform.

[0102] S108, the IoT platform receives an upgrade confirmation message and generates an upgrade instruction. The upgrade confirmation message is generated when the user confirms the upgrade after receiving the notification message.
