[0025] The embodiment of the present application provides a device upgrade method for realizing automatic firmware upgrades for devices of different types and different communication protocols, and has high versatility and scalability, which can improve development efficiency. The device upgrade method provided by the present application generates a device fingerprint for the target device, and queries the communication protocol of the target device in the configuration file based on the device fingerprint, obtains the total upgrade firmware package of the target device, and after the total upgrade firmware package passes the verification, generates a firmware data unit queue and a total package verification value based on the total upgrade firmware package, and then obtains the upgrade instruction set of the target device based on the device fingerprint. Finally, based on the communication protocol, the firmware data unit queue and the total package verification value are sent to the target device under the instruction of the upgrade instruction set to realize the upgrade of the target device. The above-mentioned device upgrade method can realize automatic firmware upgrades for devices of different types and different communication protocols, and has high versatility and scalability, which can improve development efficiency.

[0026] The device upgrade method provided in the embodiments of the present application can be applied to computer devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). It can communicate with various target devices, such as Bluetooth connections and local area network connections, to implement firmware upgrades for various target devices. The embodiments of the present application do not impose any restrictions on the specific types of computer devices.

[0027] like Figure 1 As shown, the embodiment of the present application provides a device upgrade method, including: Step S1: Generate a unique device fingerprint for each target device in the devices to be identified.

[0028] In an application, there are generally multiple devices to be identified. The target device among the devices to be identified is a trusted device. Only the target device is a device to be upgraded for firmware. Each target device corresponds to a unique device fingerprint.

[0029] Step S2: querying the communication protocol of the target device in a configuration file based on the device fingerprint.

[0030] In the application, the configuration file includes the configuration information of the target device, such as device model, device communication protocol information, upgrade instructions, service UUID (Universally Unique Identifier), firmware version, hardware version, device name, device model, etc. The configuration information of the corresponding target device can be uniquely found through a device fingerprint.

[0031] In applications, the communication protocols of different devices may vary, requiring accurate information to ensure communication quality. For example, the industrial control protocols used by end devices to communicate via Bluetooth include Modbus RTU and CANBus. These protocols differ in their data transmission frame formats: Modbus RTU uses a fixed format (address + function code + length + data + checksum), while CANBus uses a flexible format (ID + data + length + checksum).

[0032] Step S3: Obtain the total upgrade firmware package of the target device, perform firmware verification on the total upgrade firmware package, and generate a firmware verification result.

[0033] In the application, the total upgrade firmware package is the latest firmware package obtained from the upgrade server. If the total upgrade firmware package cannot be obtained from the server, the local firmware package can also be obtained locally as the total upgrade firmware package.

[0034] Step S4, when the firmware verification result indicates that the total upgrade firmware package passes the firmware verification, generates a firmware data unit queue and a total package verification value based on the total upgrade firmware package, the firmware data unit queue includes multiple firmware data units, each of the firmware data unit includes a firmware block and a block verification code corresponding to the firmware block.

[0035] In applications, the upgrade firmware package can be segmented into fixed byte blocks (e.g., 4KB per block), or adaptively divided into blocks based on the device's cache capacity. Each block is assigned a block number, which can be used to index and sequence the blocks within the upgrade firmware package. This block division reduces the amount of data transmitted per transmission, mitigates transmission failures due to network instability, supports breakpoint resuming and retransmission strategies, and facilitates block processing and verification on low-resource devices.

[0036] In the application, a block checksum is generated for each firmware block based on a preset checksum algorithm, such as a cyclic redundancy check (CRC). The firmware block and the corresponding block checksum are added to a firmware data unit queue as a firmware data unit. In the application, a total package checksum can be generated for the entire upgrade firmware package based on an integrity checksum algorithm.

[0037] Step S5: acquiring an upgrade instruction set of the target device based on the device fingerprint, wherein the upgrade instruction set includes a plurality of upgrade instructions.

[0038] In the application, the upgrade instructions in the upgrade instruction set of the target device are used to indicate the specific firmware upgrade steps of the target device. The upgrade instruction sets of different models of devices are different.

[0039] In the application, after first obtaining the target device's upgrade instruction set from the configuration file based on its device fingerprint, the target device's device fingerprint and its upgrade instruction set can be stored as a fingerprint upgrade data item in the fingerprint upgrade library. Subsequently, the target device's upgrade instruction set can be obtained from the fingerprint upgrade library based on the device fingerprint. If obtaining the upgrade instruction set from the fingerprint upgrade library fails, the upgrade instruction set can be obtained from the configuration file based on the device fingerprint again. Using the fingerprint upgrade library can speed up the acquisition of upgrade instruction sets.

[0040] Step S6: Upgrading the target device based on the communication protocol, the upgrade instruction set, the firmware data unit queue, and the total packet check value.

[0041] The device upgrade method provided in the embodiments of this application is applicable to the automated firmware upgrade of devices of different types and communication protocols, and can meet the upgrade requirements of devices of different types and communication protocols. The device upgrade method provided in this application can simultaneously upgrade the firmware of multiple devices based on multithreading, and is not limited by differences in device models, communication protocols, etc.

[0042] In one embodiment, before generating a unique device fingerprint for each target device in the devices to be identified, step S1 further includes: Step S01: Scan for devices and establish a preliminary connection with each scanned device to be identified.

[0043] Step S02: respectively obtaining service information of each device to be identified with which the preliminary connection is established.

[0044] Step S03 : matching the service information of each device to be identified with the configuration file to determine whether each device to be identified is a target device.

[0045] In the application, the service information of the device to be identified includes the device's service UUID (Universally Unique Identifier). The service information is searched in the configuration file based on the service UUID of the device to be identified. If a device with the same service UUID is found, the device to be identified is determined to be the target device.

[0046] In one embodiment, step S1, generating a unique device fingerprint for each target device among the devices to be identified, includes: Step S11: Acquire the unique identifier and service information of each target device.

[0047] Step S12: Generate a device fingerprint for each target device according to the unique identifier and the service information of each target device.

[0048] In the application, the unique identifier of the target device is a hardware unique identifier of the target device, such as a MAC address (Media Access Control Address).

[0049] In one embodiment, the total upgrade firmware package includes the latest firmware package, and step S3 of obtaining the total upgrade firmware package of the target device, performing firmware verification on the total upgrade firmware package, and generating a firmware verification result includes: Step S31: Communicate with the target device based on the communication protocol to obtain the device model and current firmware version of the target device.

[0050] Step S32: query the latest firmware version of the target device based on the device model.

[0051] Step S33: When the latest firmware version is different from the current firmware version, obtain the latest firmware package of the target device.

[0052] In most cases, the latest firmware version may be higher than the current firmware version, allowing the target device to upgrade its firmware version. In some cases, such as when the current firmware version has problems, the latest firmware version can be one version lower than the current firmware version, allowing the firmware version to be downgraded to a more secure and stable previous version.

[0053] Step S34: parsing the latest firmware package to obtain the first device model corresponding to the latest firmware package.

[0054] In the application, if the latest firmware package is an unencrypted file, it can be parsed directly. If the latest firmware package is an encrypted file, it must be decrypted according to the latest firmware package password before parsing. By parsing the first device model in the latest firmware package, the device model that the firmware package is applicable to is obtained.

[0055] Step S35 : When the first device model and the target device model are the same, a firmware verification result is generated indicating that the total upgrade firmware package has passed the firmware verification.

[0056] In the application, if the first device model and the target device model are the same, it indicates that the general upgrade firmware package is applicable to the target device and can be used for firmware upgrade of the target device, and thus a firmware verification result is generated indicating that the general upgrade firmware package has passed the firmware verification. If the first device model and the target device model are different, it indicates that the general upgrade firmware package is not applicable to the target device.

[0057] like Figure 2 As shown, in one embodiment, the step S4, when the firmware verification result indicates that the total upgrade firmware package passes the firmware verification, generates a firmware data unit queue and a total package verification value based on the total upgrade firmware package, including: Step S41 : if the firmware verification result indicates that the total upgrade firmware package passes the firmware verification, divide the total upgrade firmware package into a plurality of firmware blocks.

[0058] In this application, taking a 150KB firmware file as an example, and using Bluetooth to transmit firmware data, the maximum Bluetooth Maximum Transmission Unit (MTU) is 517 bytes. 150KB = 150 × 1,024 = 153,600 bytes. If the MTU is set to 500 bytes, the 150KB firmware file needs to be sent 308 times in a row. This means the 150 total firmware upgrade package array is divided into 308 portions, each with 500 bytes of data. Step S42: query the configuration file for a firmware package verification algorithm set corresponding to the target device according to the device fingerprint.

[0059] In applications, different devices require different verification algorithms. The verification algorithm set includes the verification algorithms required by the target device at each stage. For example, cyclic redundancy check is required in the firmware block verification stage, and integrity verification algorithms such as checksum algorithms are required in the verification stage of the total upgrade firmware package.

[0060] Step S43 , generating a total package verification value of the total upgrade firmware package and a block verification code corresponding to each firmware block according to a verification algorithm in the firmware package verification algorithm set.

[0061] In step S44 , each of the firmware blocks and the corresponding block check code are respectively combined into a firmware data unit, and the firmware data unit is added to a firmware data unit queue.

[0062] In one embodiment, step S6, upgrading the target device based on the communication protocol, the upgrade instruction set, the firmware data unit queue, and the total packet check value, includes: Step S61: Determine that the communication protocol is a protocol for communicating with the target device.

[0063] Step S62: sending the firmware unit data in the firmware data unit queue to the target device according to the upgrade steps indicated by the upgrade instructions in the upgrade instruction set.

[0064] Step S63: After the data transmission in the firmware data unit queue is completed, an upgrade verification is performed based on the total packet verification value. If the verification passes, an upgrade result indicating that the target device is successfully upgraded is generated.

[0065] like Figure 3 As shown, in one embodiment, the step S62, sending the firmware unit data in the firmware data unit queue to the target device according to the upgrade step indicated by the upgrade instruction in the upgrade instruction set, includes: Step S621: Take a firmware data unit from the head of the firmware data unit queue.

[0066] In the application, the firmware data unit queue is implemented as a queue data structure with a first-in-first-out (FIFO) feature. The data at the head of the queue is the oldest data to be queued, and the data at the tail of the queue is the latest data to be queued. One firmware data unit is taken from the head of the queue each time until the queue is empty.

[0067] Step S622: Send the firmware data unit to the target device.

[0068] In the application, before sending the firmware data unit to the target device, the target device's operating conditions are checked to determine whether the target device's current operating conditions meet the firmware upgrade requirements or meet the conditions that prohibit the firmware upgrade. For example, the firmware upgrade is prohibited when the target device's battery power is less than 5%, the battery is at high or low temperatures, the battery is being charged at high power, the voltage is unstable, or the current is abnormal.

[0069] Step S623: upon receiving confirmation information sent by the target device based on the firmware data unit, updating the upgrade progress.

[0070] In the application, the target device generates a check code based on the firmware block in the received firmware data unit and the algorithm required for firmware block verification, such as cyclic redundancy check. If the check code is equal to the block check code of the firmware block, it means that the firmware block in the firmware data unit has passed the verification, and then sends an acknowledgment message (ACK) and updates the upgrade progress.

[0071] Step S624: If the firmware data unit queue is not empty, return to step S621 to take out a firmware data unit from the head of the firmware data unit queue.

[0072] Step S625 : When the firmware data unit queue is empty, an end flag is sent to the target device.

[0073] The step S63, after the data transmission in the firmware data unit queue is completed, performing an upgrade check based on the total packet check value, and generating an upgrade result indicating that the target device has been successfully upgraded if the check passes, includes: Step S631: Receive a complete verification code sent by the target device based on the end identifier.

[0074] In the application, after receiving the end identifier, the target device combines the firmware data in all received firmware data units into a complete firmware data packet, and generates an integrity check code for the firmware data packet according to the integrity check algorithm.

[0075] Step S632: When the complete check code and the total package check value are equal, an upgrade result is generated to indicate that the target device is successfully upgraded.

[0076] In the application, each firmware block is verified through the block check code, and the complete firmware data packet composed of all firmware blocks received by the target device is verified through the integrity check code and the total packet check value, ensuring the reliability and security of the firmware data used for upgrading.

[0077] Step S633: When the complete check code and the total package check value are not equal, an upgrade result is generated to indicate that the upgrade of the target device is unsuccessful.

[0078] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

The device upgrade system can be a virtual appliance in a computer device, run by a processor of the computer device, or it can be the computer device itself.
