[0020] According to an embodiment of the present invention, a firmware upgrade method is provided, applied to home appliances. The home appliance stores basic firmware, which is a general-purpose low-level software pre-burned into the home appliance, including the basic firmware version, hardware version, and basic upgrade platform address. It consists of a network module, an information storage module, a communication module, and a firmware upgrade module. The network module can search for and connect to a default WiFi hotspot after the home appliance is powered on, and access the basic upgrade platform address after the home appliance is connected to the network. The information storage module stores information such as the basic firmware version, hardware version, basic upgrade cloud address, WiFi hotspot name, and password. The communication module reports the current firmware information and physical address to the cloud, and transmits data with the MCU on the control board. The firmware upgrade module parses, installs, and verifies newly downloaded firmware. Figure 1 This is a flowchart of a firmware upgrade method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps: Step S101: If the home device establishes a communication connection with the cloud, send the device parameters of the home device to the cloud.

[0021] The device parameters include the physical address and current firmware information. After the home appliance is powered on, its internally stored basic firmware begins running, enabling the device to connect to the local area network (LAN) and establish a communication connection with a remote firmware management and distribution platform (i.e., the cloud). After establishing a communication connection with the cloud, the home appliance sends device parameters to the cloud via its communication module. These parameters identify the home appliance's identity and status, including its physical address (e.g., MAC address (Media Access Control Address, LAN address)) and current firmware information. The current firmware information includes the current firmware type in the home appliance, which can be either basic firmware or product firmware.

[0022] Step S102: If a firmware download address is received from the cloud within a preset time period, the firmware of the target product is obtained based on the firmware download address.

[0023] The firmware download address is generated by the cloud based on analysis of the current firmware information of the home appliance, determining the current firmware type. After the home appliance sends its device parameters to the cloud, the cloud first analyzes the current firmware information within those parameters to determine whether the device is running only basic firmware or also includes product firmware. Based on this determination, the cloud further queries its locally stored database for the product model and target firmware version information pre-bound to the home appliance's physical address. If the query is successful, the cloud generates the corresponding target product firmware download address and sends it to the device. If the home appliance receives this address within a preset timeframe, its firmware upgrade module will download the complete data package of the target product firmware from the specified network location using that address.

[0024] If the current firmware information only includes basic firmware information, then the current firmware type is determined to be basic firmware. If the current firmware information also includes product firmware information, then the current firmware type is determined to be product firmware.

[0025] Step S103: Upgrade the firmware based on the target product firmware.

[0026] After the target product firmware data package is downloaded, the home appliance device performs integrity verification and security analysis on the downloaded data package to ensure it is compatible with the device. Then, it upgrades the old firmware stored in the device's memory. The upgrade operation includes erasing and writing to the firmware storage partition. After the upgrade, the home appliance device stores the latest target product firmware.

[0027] The firmware upgrade method provided in this invention is applied to home appliances. The home appliances store basic firmware. If the home appliances establish a communication connection with the cloud, they send device parameters to the cloud, including the physical address and current firmware information. If a firmware download address is received from the cloud within a preset time period, the target product firmware is obtained based on the firmware download address. The firmware download address is issued by the cloud based on the current firmware type determined by analyzing the current firmware information of the home appliances. A firmware upgrade is then performed based on the target product firmware. In this method, after connecting to the cloud, the home appliances can automatically report device parameters, thereby receiving the firmware download address sent by the cloud when a firmware upgrade is needed, obtaining the target product firmware based on the firmware download address, and then performing a firmware upgrade, thus improving the accuracy and efficiency of firmware upgrades.

[0028] In some optional implementations, the method further includes: if the firmware download address sent by the cloud is not received within a preset time period, then the firmware upgrade is terminated.

[0029] After a home appliance sends its device parameters to the cloud, the cloud checks its database for matching information. This includes checking if the device's physical address, product model, or firmware version is pre-stored. If not, the cloud will not send a firmware download link. In this scenario, if the home appliance does not receive a firmware download link after a preset time, it indicates that the device has not yet been registered with the cloud.

[0030] After the home appliances send device parameters to the cloud, if there is a temporary failure of the cloud server or network communication interruption, the home appliances can end the firmware upgrade process after waiting for a preset time. That is, they can exit in time when they cannot interact with the platform normally, so as to avoid affecting the processing efficiency due to excessive waiting.

[0031] The preset duration is set according to actual needs. Optionally, the preset duration is set to 3 minutes. In some optional implementations, after step S103 above, the method further includes: Step S201: Restart the home appliances and establish a communication connection with the cloud after restarting.

[0032] After the target product firmware is written, the home appliance's control system triggers a hard reboot or system reset. The reboot signal resets the device's central processing unit (CPU) and reloads and executes the firmware from the program's start address in memory. After rebooting, the home appliance runs the target product firmware, reconnects to the local area network via the networking module, and establishes a communication connection with the cloud.

[0033] Step S202: Send the physical address and current firmware information to the cloud.

[0034] After establishing a communication connection with the cloud, the home device sends its current firmware information and physical address to the cloud. This step is identical to step S101.

[0035] Step S203: Receive the verification result of the current firmware information sent by the cloud.

[0036] After the home appliance sends its physical address and current firmware information, it waits for a response from the cloud. Upon receiving the physical address and current firmware information, the cloud executes a verification logic: it compares the version number in the current firmware information sent by the home appliance with a preset target firmware version number stored in the cloud that corresponds to the physical address of the home appliance, generating a verification result. The cloud then sends this verification result to the home appliance, which receives it via a communication link.

[0037] Step S204: If the verification result indicates that the current firmware information is consistent with the firmware information stored in the cloud, then send a success message to the cloud to indicate that the firmware upgrade was successful.

[0038] If the verification result indicates that the current firmware information of the home device is consistent with the firmware information stored in the cloud, it means that the firmware of the home device is the latest version. In this case, the home device will actively send a predefined message to the cloud to indicate that the firmware upgrade was successful, i.e., a success message.

[0039] In some alternative implementations, after step S203 above, the method further includes: Step S205: If the verification result indicates that the current firmware information is inconsistent with the firmware information stored in the cloud, then within a preset time period, receive the firmware download address sent by the cloud, and obtain the target product firmware based on the firmware download address.

[0040] If the cloud verification determines that the current firmware information of the home device is inconsistent with the firmware information stored in the cloud, it indicates that the local firmware of the home device has not been upgraded to the latest firmware version. The cloud sends a firmware download address to the home device. If the home device receives this address within a preset time, its firmware upgrade module will download the complete data package of the target product firmware from the specified network location based on this address.

[0041] Step S206: Upgrade the firmware based on the target product firmware.

[0042] After the target product firmware data package is downloaded, the home appliance device performs integrity verification and security analysis on the downloaded data package to ensure it is compatible with the device. Then, it upgrades the old firmware stored in the device's memory. The upgrade operation includes erasing and writing to the firmware storage partition. After the upgrade, the home appliance device stores the latest target product firmware.

[0043] According to embodiments of the present invention, a firmware upgrade method is provided, applied in the cloud. The cloud database stores the latest product firmware corresponding to home appliances at various physical addresses. The product firmware includes product information, firmware version, hardware version, and cloud address. The home appliances also include an information storage module, a network module, a communication module, an upgrade module, and a data parsing module. The information storage module is used to read firmware information, product information, physical address, WiFi hotspot name and password, and cloud address. The network module is used to search for and connect to the stored specified WiFi hotspots. The communication module is used to send firmware information, product information, physical address, and OTA firmware (a firmware package that can be directly downloaded and installed on the device via a wireless network) to the cloud backend, as well as to report and receive device control information. The upgrade device verifies whether the firmware sent from the cloud is correct; if correct, it overwrites the old firmware stored in the MCU with the new firmware. The function parsing module receives information from the home appliances, parses it, forwards it to the communication module, and receives information from the communication module, parses it, and forwards the information to the home appliances.

[0044] Figure 2 This is a flowchart of a firmware upgrade method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S301: Receive device parameters sent by home appliances.

[0045] The device parameters include at least the physical address and current firmware information. After the home appliance is powered on, its internally stored basic firmware begins running, enabling the device to connect to the local area network (LAN) and establish a communication connection with a remote firmware management and distribution platform (i.e., the cloud). After establishing a communication connection with the cloud, the home appliance sends device parameters to the cloud via its communication module. These parameters identify the home appliance's identity and status, including its physical address (e.g., MAC address (Media Access Control Address, LAN address)) and current firmware information. The current firmware information includes the current firmware type in the home appliance, which can be either basic firmware or product firmware.

[0046] Step S302: Analyze the current firmware information to obtain the current firmware type of the home device.

[0047] After a home appliance sends its device parameters to the cloud, the cloud first analyzes the current firmware information within those parameters. This analysis determines whether the device is running only basic firmware or also includes product firmware. Based on this determination, the cloud further queries its locally stored database for the product model and target firmware version information pre-bound to the device's physical address. If the current firmware information only includes basic firmware, it is determined to be basic firmware; otherwise, it is determined to be product firmware.

[0048] Step S303: Send a firmware download address to the home device based on the current firmware type, so that the home device can obtain the target product firmware based on the firmware download address and perform firmware upgrade based on the target product firmware.

[0049] After determining the current firmware type, if it's basic firmware, a firmware download address is sent to the home appliance. If it's product firmware, the system analyzes whether the product firmware on the home appliance matches the product firmware stored in the cloud. If they don't match, a firmware download address is sent to the home appliance. If the home appliance receives this address within a preset time, its firmware upgrade module will download the complete data package of the target product firmware from the specified network location based on that address. After the target product firmware data package is downloaded, the home appliance performs integrity verification and security analysis on the downloaded data package to ensure it's suitable for the device. Then, it upgrades the old firmware stored in the device's memory. The upgrade operation includes erasing and writing to the firmware storage partition. After the upgrade, the home appliance stores the latest target product firmware.

[0050] In some optional implementations, if the current firmware type is basic firmware, the step S303 above, which involves sending the firmware download address to the home device based on the current firmware type, includes: verifying the physical address of the home device to determine whether the target product firmware of the home device is stored locally in the cloud; if the target product firmware of the home device is stored locally in the cloud, then sending the firmware download address to the home device.

[0051] The cloud verifies the physical address of the home appliance and determines whether its database stores the product firmware associated with that physical address, i.e., the target product firmware. The target product firmware is the latest version of the firmware available for the home appliance stored in the cloud. If the cloud stores the target product firmware locally, it sends the firmware download address to the home appliance.

[0052] In some optional implementations, if the current firmware type is product firmware, the step S303 above, which involves sending the firmware download address to the home device based on the current firmware type, includes: comparing the current firmware information of the home device with the firmware information stored locally in the cloud; if the current firmware information is inconsistent with the locally stored firmware information, then sending the firmware download address to the home device.

[0053] The current firmware information includes at least the product information of the home appliance, the product firmware version, the hardware version, and the product cloud address. If the current firmware type is product firmware, it means that the home appliance has product firmware stored. By comparing the current firmware information of the home appliance with the firmware information stored locally in the cloud, it is determined whether the product firmware of the home appliance is the latest version. If the current firmware information is inconsistent with the locally stored firmware information, it means that the product firmware of the home appliance is not the latest version and needs to be upgraded. Therefore, the cloud sends the firmware download address to the home appliance.

[0054] In some alternative implementations, after comparing the current firmware information of the home device with the locally stored firmware information, the method further includes: if the current firmware information matches the locally stored firmware information, then sending a firmware upgrade success command to the home device.

[0055] If the current firmware information matches the locally stored firmware information, it indicates that the home appliance's product firmware is the latest version and does not require an upgrade. In this case, a command is sent to the home appliance to indicate that the firmware upgrade was successful.

[0056] According to an embodiment of the present invention, a firmware upgrade method is provided, comprising: if a home appliance is connected to the cloud, sending device parameters of the home appliance to the cloud, the device parameters including a physical address and current firmware information; the cloud analyzing the current firmware information of the home appliance to obtain the current firmware type of the home appliance, and sending a firmware download address to the home appliance based on the current firmware type; if the home appliance receives the firmware download address sent by the cloud within a preset time period, obtaining the target product firmware based on the firmware download address; and the home appliance performing a firmware upgrade based on the target product firmware.

[0057] Once the home appliance is powered on, its internally stored firmware begins running, enabling it to connect to the local area network and establish a communication connection with the cloud. After establishing this connection, the home appliance sends device parameters to the cloud via its communication module. These parameters identify the device and its status, including its physical address and current firmware information. The current firmware information includes the current firmware type, which can be either basic firmware or product firmware.

[0058] After the home appliance sends its device parameters to the cloud, the cloud first analyzes the current firmware information within those parameters. It analyzes the firmware type to determine whether the home appliance is currently running only basic firmware or also includes product firmware. Based on this determination, the cloud further queries its locally stored database for the product model and target firmware version information pre-bound to the home appliance's physical address. If the query is successful, the cloud generates the corresponding firmware download address for the target product firmware and sends it to the device. If the home appliance receives this address within a preset timeframe, its firmware upgrade module will download the complete data package of the target product firmware from the specified network location based on that address.

[0059] After the target product firmware data package is downloaded, the home appliance device performs integrity verification and security analysis on the downloaded data package to ensure it is compatible with the device. Then, it upgrades the old firmware stored in the device's memory. The upgrade operation includes erasing and writing to the firmware storage partition. After the upgrade, the home appliance device stores the latest target product firmware.
