Description

Technical Field

[0001] This invention relates to the field of equipment upgrade technology, and in particular to an equipment upgrade method, apparatus, intelligent power supply and storage medium. Background Technology

[0002] With the development of technology, various embedded products are increasingly entering people's lives, and upgrading embedded products has always been a key focus of product development. Continuous product upgrades can improve the user experience, address user pain points, and enhance product competitiveness without increasing user costs. However, if an unexpected power outage occurs during the upgrade process, the device firmware may only be partially burned, causing the device to fail to boot. Furthermore, some products may be unable to undergo OTA upgrades due to limitations of the main control chip. Therefore, resolving the issue of some products being unable to upgrade or experiencing irrecoverable power outages during upgrades is of paramount importance in product hardware and software design. Summary of the Invention

[0003] This invention provides a device upgrade method, apparatus, intelligent power supply, and storage medium, which solves the problem of device failure and inability to start due to power loss during the upgrade process.

[0004] According to one aspect of the present invention, a device upgrade method is provided, comprising:

[0005] When the smart power supply of the device to be upgraded detects that the upgrade event of the device to be upgraded has been triggered, the smart power supply sends a download request broadcast.

[0006] The smart power supply determines the download device from all smart devices that respond to the download request broadcast, and sends the upgrade configuration information of the device to be upgraded to the download device, so that the download device can obtain the device firmware corresponding to the device to be upgraded based on the upgrade configuration information.

[0007] The smart power supply acquires the device firmware sent by the downloading device and upgrades the device to be upgraded based on the device firmware.

[0008] According to another aspect of the present invention, a device upgrade apparatus is provided, comprising:

[0009] The proxy download request broadcasting module is used to send a proxy download request broadcast when the smart power supply of the device to be upgraded detects that the upgrade event of the device to be upgraded has been triggered.

[0010] The upgrade configuration information sending module is used by the smart power supply to determine the download device from all smart devices that respond to the download request broadcast, and send the upgrade configuration information of the device to be upgraded to the download device, so that the download device can obtain the device firmware corresponding to the device to be upgraded based on the upgrade configuration information.

[0011] The device upgrade module is used by the smart power supply to obtain the device firmware sent by the downloading device, and to upgrade the device to be upgraded based on the device firmware.

[0012] According to another aspect of the present invention, a smart power supply is provided, the smart power supply comprising:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the device upgrade method according to any embodiment of the present invention.

[0016] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the device upgrade method described in any embodiment of the present invention.

[0017] In the device upgrade scheme of this invention, when the smart power supply of the device to be upgraded detects that an upgrade event of the device to be upgraded has been triggered, the smart power supply sends a download request broadcast. The smart power supply determines the download device from all smart devices responding to the download request broadcast and sends the upgrade configuration information of the device to be upgraded to the download device, so that the download device can obtain the device firmware corresponding to the device to be upgraded based on the upgrade configuration information. The smart power supply obtains the device firmware sent by the download device and upgrades the device to be upgraded based on the device firmware. The technical solution provided by this invention solves the problem of device bricking and inability to boot due to power failure during device upgrades. It not only removes the limitation of the main control chip on device upgrades, thus enabling upgrade operations on any device and improving device reliability, but also eliminates the need for a boot program and backup partitions, reducing flash memory usage.

[0018] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of the present invention, nor is it intended to limit the scope of the invention. Other features of the invention will become readily apparent from the following description. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] In related technologies, different products employ different upgrade strategies. Current upgrade solutions mainly include: Solution 1: Online upgrades are not supported for some products with simple functions and low costs. Solution 2: Devices are not backed up, and power outages are not permitted during the upgrade process. Solution 3: Devices use an A+B upgrade scheme. Specifically, a boot program is first burned into the device. The device has two built-in application programs, A and B. When the device runs from partition A, an upgrade will upgrade partition B. Once partition B's upgrade is complete and verification is successful, the bootloader switches to partition B as the running partition. If the upgrade fails or verification fails, the running partition is not switched. This process is repeated for each upgrade. Solution 4: Devices use an A+A upgrade scheme. Specifically, a boot program is first burned into the device. The device has two built-in identical application programs, A1 and A2. The device boots from partition A1 each time. During each program upgrade, the upgrade package is burned to the backup partition A2 and verified. Once verification is successful, an upgrade flag is configured, and the device restarts. After the device restarts, it checks whether the upgrade flag is set and also checks the version information of the backup partition A2. If the upgrade flag is set, it copies the latest program from the backup partition A2 to the running partition A1 and then starts the device.

[0028] However, all four upgrade solutions mentioned above still have various problems and cannot truly guarantee a permanent upgrade without bricking the device. Solution 1: Due to certain chip selection issues, OTA upgrades are not possible. Serious problems necessitate factory repair, hindering user experience and competitiveness. Solution 2: The device lacks a backup partition, saving flash space, but power outages during the upgrade process can corrupt the device's operating program, preventing normal startup and remote recovery, requiring factory repair. Solutions 3 and 4: By adding a backup partition, the problem of device failure during upgrades due to power loss is minimized, but the presence of a backup partition leads to some flash memory waste. Furthermore, both solutions include a boot program. While this partition usually doesn't need upgrading, it may be necessary in special cases, such as flash partition changes. Power outages during boot program upgrades still present the same problems as Solution 2, failing to ensure true device recovery.

[0029] Example 1

[0030] Figure 1 This is a flowchart illustrating a device upgrade method according to Embodiment 1 of the present invention. This embodiment is applicable to upgrading smart devices. The method can be executed by a device upgrade device, which can be implemented in hardware and / or software and can be configured within a smart power supply. Figure 1 As shown, the method includes:

[0031] S110. When the smart power supply of the device to be upgraded detects that the upgrade event of the device to be upgraded has been triggered, the smart power supply sends a download request broadcast.

[0032] The device to be upgraded can be any smart device, such as smart home devices and smart mobility devices. For example, let's take a smart home device as an example. Figure 2 This is a schematic diagram illustrating the electrical connection between a smart device and a smart power supply, provided as an embodiment of the present invention. Figure 2As shown, to reduce the number of devices connected to the home network, the smart power supply does not connect to the internet independently. Instead, the smart power supplies of various smart devices can communicate with each other via power line carrier communication. This interoperability between smart power supplies, between smart devices and smart power supplies, and through the smart device connection scheme, enables communication between the smart power supply and the home network. The smart power supply can be electrically connected to the smart device via a USB cable. The power line in the USB cable supplies power to the smart device, while the data line is used for data communication and transmission between the smart power supply and the smart device. Different interface protocols are implemented for different smart devices, such as SPI, UART, and SWD. When the smart power supply detects a change in power consumption from zero to some, it considers a smart device to be connected. The smart power supply sends a keep-alive message to the smart device using a pre-defined communication protocol to maintain the device's connection. Simultaneously, it obtains and saves the smart device's firmware version, firmware download address, Flash type, upgrade protocol, etc.

[0033] In this embodiment of the invention, the smart power supply electrically connected to the device to be upgraded via a USB cable is referred to as the smart power supply of the device to be upgraded. When the smart power supply of the device to be upgraded detects that an upgrade event of the device to be upgraded has been triggered, the smart power supply of the device to be upgraded broadcasts a download request. For example, when the smart power supply of the device to be upgraded receives an upgrade instruction sent by the device to be upgraded, it determines that the smart power supply of the device to be upgraded has detected that an upgrade event of the device to be upgraded has been triggered.

[0034] Optionally, the smart power supply of the device to be upgraded detects that an upgrade event of the device to be upgraded has been triggered, including: determining that an upgrade event of the device to be upgraded has been triggered when the smart power supply of the device to be upgraded detects that the device to be upgraded is in an abnormal state; or, determining that an upgrade event of the device to be upgraded has been triggered when the smart power supply of the device to be upgraded receives an upgrade command sent by the device to be upgraded. In this embodiment of the invention, when the smart power supply of the device to be upgraded detects that the device to be upgraded is in a suspended state, it determines that the device to be upgraded is in an abnormal state. Optionally, the smart power supply of the device to be upgraded detects that the device to be upgraded is in an abnormal state, including: determining that the device to be upgraded is in an abnormal state when the smart power supply of the device to be upgraded cannot keep the device to be upgraded alive; or, the smart power supply of the device to be upgraded acquires the power consumption waveform of the device to be upgraded, and determines that the device to be upgraded is in an abnormal state when the power consumption waveform meets preset power consumption abnormality characteristics. For example, if the device to be upgraded is in a suspended state, the device to be upgraded cannot keep the device to be upgraded alive. Therefore, if the smart power supply of the device to be upgraded detects that it cannot keep the device to be upgraded alive, it determines that the device to be upgraded is in an abnormal state. For another example, the smart power supply of the device to be upgraded acquires the power consumption waveform of the device to be upgraded and performs power consumption waveform detection. If the power consumption waveform of the device to be upgraded meets the preset power consumption abnormality characteristics, such as the power consumption waveform of the device to be upgraded meeting the characteristics of abnormal device operation or continuous restart, then it is determined that the device to be upgraded is in an abnormal state.

[0035] When the smart power supply of the device to be upgraded detects that the device is in an abnormal state, it determines that the upgrade event of the device to be upgraded has been triggered. Optionally, if the user needs to force an upgrade of the device to be upgraded, the user can send an upgrade command to the device to be upgraded. The device to be upgraded responds to the upgrade command input by the user and sends an upgrade command to the smart power supply through the main control chip. When the smart power supply receives the upgrade command sent by the main control chip of the device to be upgraded, it determines that the upgrade event of the device to be upgraded has been triggered.

[0036] When the smart power supply of the device to be upgraded detects that the upgrade event of the device to be upgraded has been triggered, the smart power supply of the device to be upgraded enters the master control upgrade mode and broadcasts a download request through the power line carrier unit.

[0037] S120. The smart power supply determines the downloading device from all smart devices that respond to the downloading request broadcast, and sends the upgrade configuration information of the device to be upgraded to the downloading device, so that the downloading device can obtain the device firmware corresponding to the device to be upgraded based on the upgrade configuration information.

[0038] In this embodiment of the invention, after the smart power supply broadcasts a download request, all other smart devices capable of executing the download request respond via power line carrier communication through their connected smart power supply. These other smart devices that send download responses are referred to as smart devices responding to the download request broadcast. There can be one or more smart devices responding to the download request broadcast; this embodiment does not limit the number of smart devices responding to the download request broadcast. The smart power supply determines the download device from all smart devices responding to the download request broadcast. For example, it can randomly select one smart device from all smart devices responding to the download request broadcast, or it can select the smart device that sends the fastest download response, or it can determine the download device based on a pre-set download device selection strategy. It should be noted that this embodiment does not limit the method of determining the download device.

[0039] After identifying the device to be upgraded, the smart power supply establishes point-to-point communication with it. The smart power supply sends upgrade configuration information, such as the model, firmware version, and firmware download address of the device to be upgraded, to the device, enabling it to obtain the corresponding firmware. For example, the device can request to download the firmware corresponding to the device to be upgraded from the firmware download address based on the model and firmware version information.

[0040] S130, the smart power supply obtains the device firmware sent by the downloading device, and upgrades the device to be upgraded based on the device firmware.

[0041] In this embodiment of the invention, after the proxy download device obtains the device firmware corresponding to the device to be upgraded, it can transmit the device firmware to the smart power supply of the device to be upgraded via power line carrier communication. The smart power supply obtains the device firmware transmitted by the proxy download device and upgrades the device to be upgraded based on the device firmware. Optionally, the smart power supply obtaining the device firmware sent by the proxy download device includes: the smart power supply obtaining the device firmware sent by the smart power supply of the proxy download device via power line carrier communication; wherein, after the proxy download device obtains the device firmware corresponding to the device to be upgraded, the proxy download device sends the device firmware to the smart power supply of the proxy download device. It can be understood that after the proxy download device obtains the device firmware corresponding to the device to be upgraded, the proxy download device sends the device firmware to the smart power supply of the proxy download device, the smart power supply of the proxy download device receives the device firmware, and transmits the device firmware to the smart power supply of the device to be upgraded via power line carrier communication.

[0042] Optionally, upgrading the device to be upgraded based on the device firmware includes: performing a power-off and restart operation on the device to be upgraded, and simultaneously switching the communication interface with the device to be upgraded to the corresponding device upgrade mode according to the flash type of the device to be upgraded; upgrading the device to be upgraded based on the device firmware in the device upgrade mode. In this embodiment of the invention, after receiving the device firmware sent by the downloading device, the smart power supply of the device to be upgraded performs a forced power-off and restart operation on the device to be upgraded, and simultaneously switches the communication interface between the smart power supply and the device to be upgraded to the corresponding device upgrade mode according to the obtained flash type of the device to be upgraded. The device upgrade mode corresponding to the communication interface between the smart power supply and the device to be upgraded varies depending on the flash type of the device to be upgraded. The smart power supply transmits the device firmware to the device to be upgraded based on the communication protocol corresponding to the device upgrade mode, so that the device to be upgraded can be upgraded based on the device firmware. Figure 2 As shown, the flash memory of a smart device can be located either inside or outside the main control chip. Flash memory located inside the main control chip is called internal flash, and flash memory located outside the main control chip is called external flash. When the flash memory of a smart device is external, the data line in the USB cable used for electrical connection between the smart power supply and the smart device connects both the main control chip and the external flash. However, at any given time, the smart device can only choose to communicate with the smart power supply via either the main control chip or the external flash through the link selection unit. When the smart device fails to boot or in the default configuration, the smart power supply communicates with the external flash in the smart device. When the smart device is functioning normally, the smart device switches to communication between the main control chip and the smart power supply via the link switching unit. When the smart device has built-in flash memory, the smart power supply is electrically connected to the programming port of the smart device's main control chip through the data line in the USB cable. When the smart device is functioning normally, the smart power supply communicates with the smart device's main control chip. When the smart device is malfunctioning, the smart power supply performs the programming function. In the process of the smart power supply performing the programming function, communication protocols such as UART, SPI, SWD, and USB can be used.

[0043] Optionally, the communication interface with the device to be upgraded is switched to the corresponding device upgrade mode according to the flash type of the device to be upgraded. This includes: when the flash type of the device to be upgraded is external flash, controlling the communication link between the smart power supply and the external flash of the device to be upgraded to be established, and switching the communication interface with the device to be upgraded to SPI mode; upgrading the device to be upgraded based on the device firmware in the device upgrade mode includes: the smart power supply writing the device firmware into the external flash of the device to be upgraded in the SPI mode, so that the device to be upgraded is upgraded based on the device firmware written into the external flash. For example, when the flash of the device to be upgraded is external flash, controlling the communication link between the smart power supply and the external flash of the device to be upgraded to be established, that is, controlling the smart power supply to communicate with the external flash of the device to be upgraded, and switching the communication interface of the smart power supply to SPI mode. In SPI mode, the smart power supply directly writes the device firmware of the device to be upgraded into the external flash of the device to be upgraded based on the SPI communication protocol, and the device to be upgraded is upgraded based on the device firmware written into the external flash.

[0044] Optionally, the communication interface with the device to be upgraded is switched to device upgrade mode according to the flash type and device upgrade protocol of the device to be upgraded. This includes: when the flash type of the device to be upgraded is built-in flash, controlling the communication link between the smart power supply and the main control chip of the device to be upgraded to be connected, and switching the communication interface with the device to be upgraded to the upgrade interface mode supported by the device to be upgraded; upgrading the device to be upgraded based on the device firmware in the device upgrade mode, including: the smart power supply sends the device firmware to the main control chip of the device to be upgraded based on the device upgrade protocol in the upgrade interface mode supported by the device to be upgraded, so that the device to be upgraded can be upgraded based on the device firmware. For example, if the flash memory of the device to be upgraded is built-in, the communication link between the intelligent power supply and the main control chip of the device to be upgraded is established. This means the intelligent power supply communicates with the main control chip of the device to be upgraded and switches the communication interface with the device to the upgrade interface mode supported by the device. The upgrade interface mode supported by the device corresponds to the interface protocol of the device to be upgraded. For example, if the interface protocol of the device to be upgraded is UART, then the upgrade interface mode supported by the device is UART mode; similarly, if the interface protocol of the device to be upgraded is SWD, then the upgrade interface mode supported by the device is SWD mode. Under the upgrade interface mode supported by the device to be upgraded, the intelligent power supply burns the device firmware into the main control chip of the device to be upgraded based on the device upgrade protocol. For example, if the upgrade interface mode is SWD mode, then the intelligent power supply burns the device firmware into the main control chip of the device to be upgraded based on the SWD protocol. The device to be upgraded then performs an upgrade based on the device firmware burned into the main control chip.

[0045] Optionally, once the upgrade of the device is complete, the smart power supply will force a power outage and restart of the device.

[0046] For example, Figure 3 This is a schematic diagram of a device upgrade process provided by an embodiment of the present invention. Combined with the description of the above embodiments, it can be understood that... Figure 3 To understand, it will not be discussed further here. Figure 3 To elaborate further.

[0047] The device upgrade method of this invention involves the following steps: When the smart power supply of the device to be upgraded detects that an upgrade event of the device to be upgraded has been triggered, the smart power supply broadcasts a download request. The smart power supply determines a download device from all smart devices responding to the download request broadcast and sends the upgrade configuration information of the device to be upgraded to the download device, so that the download device obtains the device firmware corresponding to the device to be upgraded based on the upgrade configuration information. The smart power supply obtains the device firmware sent by the download device and upgrades the device to be upgraded based on the device firmware. The technical solution provided by this invention solves the problem of device bricking and inability to boot due to power failure during device upgrades. It not only removes the limitation of the main control chip for device upgrades, enabling upgrades for any device and improving device reliability, but also eliminates the need for a boot program and backup partitions, reducing flash memory usage.

[0051] The upgrade configuration information sending module 420 is used by the smart power supply to determine the download device from all smart devices that respond to the download request broadcast, and to send the upgrade configuration information of the device to be upgraded to the download device, so that the download device can obtain the device firmware corresponding to the device to be upgraded based on the upgrade configuration information.
