[0021] Figure 1A schematic diagram of a system architecture for implementing a device activation method provided in an embodiment of the present application, wherein the system architecture includes: a terminal 120, a cloud 140 and a wireless communication module 160.

[0022] The terminal 120 installs and runs an application program having a device activation method. The terminal 120 is used to send an acquisition request to the wireless communication module 160 of the device, and is also used to send an activation instruction to the wireless communication module 160 .

[0023] The terminal 120 is connected to the cloud 140 via a wireless network or a wired network.

[0024] The cloud 140 includes at least one of a server, multiple servers, a cloud computing platform, and a virtualization center. Schematically, the cloud 140 includes a processor 144 and a memory 142, and the memory 142 includes a display module 1421, a control module 1422, and a receiving module 1423.

[0025] The wireless communication module 160 is used to implement information exchange between the main controller and the activated terminal, and is also used to parse and reorganize the received information.

[0026] Optionally, the device types of the terminal include: at least one of a smart phone, a tablet computer, an e-book reader, a Moving Picture Experts Group Audio Layer III (MP3) player, a Moving Picture Experts Group Audio Layer IV (MP4) player, a laptop computer and a desktop computer.

[0027] Those skilled in the art will appreciate that the number of the above terminals may be more or less. For example, the above terminal may be only one, or the above terminals may be dozens or hundreds, or more. The embodiment of the present application does not limit the number of terminals and device types.

[0028] The present application provides a device activation method, such as Figure 2 As shown, the method includes: S101, in response to an acquisition request sent by an activation terminal, acquiring a target serial number of a main controller from a main controller of a device, and sending the target serial number to the activation terminal.

[0029] In an embodiment of the present application, the method is applied to a wireless communication module of a device, and the wireless communication module is responsible for wireless data transmission between the device and other devices or networks. The wireless communication module is a component that integrates wireless communication protocols and hardware, and is used to implement wireless data transmission functions in various smart devices. These modules can be embedded in various devices, such as mobile phones, smart home devices, wearable devices, etc., to achieve wireless network connection and data exchange. For example, the wireless communication module is a combo module, which is a module that integrates multiple wireless communication functions. It integrates different wireless communication protocols (such as Wi-Fi, Bluetooth, GPS, etc.) into one module, which facilitates the device to realize multiple communication functions without the need for additional hardware.

[0030] In an embodiment of the present application, the activation terminal is a terminal operated by an installer. After installing the device, the installer activates the device through the activation terminal. For example, if the device is a smart clothes dryer, after the installer installs the smart clothes dryer at home, if the installer wants to use the smart clothes dryer, the installer must activate the smart clothes dryer through the activation terminal he carries.

[0031] In the embodiments of the present application, a device refers to a device that needs to complete an activation process before it can be used normally, and the device is a device that can interact with an activation terminal through wireless communication. The device can be a smart home device, such as a smart lock, a smart light, and a smart appliance; the device can also be a personal electronic device, such as a smart watch, a fitness device, an e-reader, etc.; the device can also be an industrial controller, such as a PLC control, an industrial robot, etc.; the device can also be other electronic devices that need to be activated remotely or locally.

[0032] In the embodiment of the present application, the main controller of the device refers to the core processing unit responsible for managing and coordinating the various components and functions of the device. The main controller is responsible for starting and initializing the device, including loading the operating system. Therefore, the activation process of the device needs to be executed by the main controller.

[0033] In an embodiment of the present application, the serial number of the main controller is a unique identifier of the main controller of the device, which is used to track and manage the main controller. The serial number of the main controller is assigned during the production stage of the device. During the production process, the serial number of the main controller will be burned into the memory of the main controller. The serial number helps to ensure the identity authentication of the device and prevent counterfeiting.

[0034] In an embodiment of the present application, the acquisition request is sent by the activation terminal after determining that the device is in a state to be activated. That is to say, when the installer determines that the device is in a state to be activated and the above-mentioned device is a device to be activated, it will first establish a wireless communication connection with the wireless communication module of the device, and then send an acquisition request to the wireless communication module to obtain the target serial number of the main controller of the device. Therefore, after the wireless communication module receives the acquisition request sent by the activation terminal, it interacts with the main controller of the device, obtains the target serial number of the main controller from the main controller, and finally sends the above-mentioned target serial number to the activation terminal.

[0035] In an embodiment of the present application, the target serial number is sent to the activation terminal so that the activation terminal sends the target serial number to the cloud.

[0036] In an embodiment of the present application, if the activation terminal wants to activate the device, it first needs to determine through the cloud whether the device meets the activation conditions. Therefore, after the wireless communication module obtains the target serial number of the main controller according to the acquisition request, it returns the target serial number to the activation terminal, so that the activation terminal can send the target serial number of the main controller to the cloud to determine whether the device meets the activation conditions.

[0037] S102: Receive an activation instruction sent by an activation terminal.

[0038] In an embodiment of the present application, the activation instruction includes a target activation code of the main controller; the target activation code is determined by a target serial number.

[0039] In an embodiment of the present application, the activation instruction is used to instruct the activation of the device, and the target activation code is used to activate the device, complete the configuration of the device and enable the functions. A unique activation code is assigned to the device when it is produced, and then the activation code is stored in the device's memory, and the correspondence between the serial number and the activation code is stored in the cloud, so that the activation device can obtain the target activation code from the cloud according to the target serial number when activating the device.

[0040] In the embodiment of the present application, after the cloud determines that the device meets the activation conditions based on the target serial number of the main controller, it will send an activation instruction carrying the target activation code to the activation terminal.

[0041] In an embodiment of the present application, after the cloud receives the target serial number sent by the activation terminal, it determines whether the device meets the activation conditions based on the serial number. If the device meets the activation conditions, it obtains the target activation code corresponding to the target serial number, and then sends an activation instruction containing the target activation code to the activation terminal. The activation instruction forwards the activation instruction containing the target activation code to the wireless communication module, so that the wireless communication module receives the activation instruction sent by the activation terminal.

[0042] In an embodiment of the present application, the activation condition is used to ensure that the device meets specific requirements or conditions, thereby ensuring the legality, functionality and security of the device. For example, the activation condition may be whether the target serial number is recorded in the serial number set of the main controller of the registered device. The cloud will record the serial number of the main controller of the registered device in the serial number set. If the target serial number is recorded in the serial number set, it is considered that the device does not meet the activation condition.

[0043] S103, parsing the activation instruction, generating an activation instruction in a preset format according to the parsing result, and sending the activation instruction to the main controller.

[0044] In an embodiment of the present application, the data format of the activation instruction sent by the activation terminal to the wireless communication module of the device is different from the data format of the activation instruction in a preset format sent to the main controller after the wireless communication module parses and reorganizes the activation instruction. The data format of the activation instruction sent by the activation terminal to the wireless communication module is a first data format, that is, the wireless communication module and the activation terminal use the first data format for information exchange, and the activation instruction in a preset format sent by the wireless communication module to the main controller uses a preset data format, that is, the information exchange between the wireless communication module and the main controller uses a preset data format.

[0045] In the embodiment of the present application, after receiving the activation instruction, the wireless communication module first parses the activation instruction, and determines the instruction type, the device to which the instruction is directed, and the specific information carried by the instruction based on the parsing result. For example, when the instruction is an activation instruction, the instruction type, target activation code, device type of the device to be activated, target serial number of the main controller of the device to be activated, and other information can be obtained based on the parsing result. The wireless communication module constructs an activation instruction in a preset format based on the above information, and then sends an activation instruction in a preset format containing information such as the instruction type, target activation code, and target serial number of the main controller to the main controller.

[0046] In an embodiment of the present application, the parsing result includes at least one of the following: instruction type, device type, checksum, instruction length, and instruction content.

[0047] In one example, the data format of the activation instruction sent by the activation terminal to the wireless communication module is shown in Table 1 below:

[0048] Table 1 Among them, the synchronization header length is 1 BYTE, which is used to characterize the instruction type. For example, the instruction type can be divided into function instructions, activation instructions, and lock instructions; the device type length is 1 BYTE, which is used to characterize different types of devices. For example, 0X02 represents a smart clothes dryer and 0X03 represents a smart door lock; the additional data length is used to characterize the length of the entire instruction; the message data length is greater than 12 BYTE, which is used to carry specific instruction content. For example, in the activation instruction, the target activation code and target serial number are stored in the message data; the checksum length is 1 BYTE, which is used for the wireless communication module to verify whether the activation instruction is legal and whether the content has been tampered with.

[0049] In another example, the data format of the activation instruction in a preset format sent by the wireless communication module to the main controller is shown in Table 2 below:

[0050] Table 2 Among them, the synchronization header length is 1BYTE, which is used to characterize whether the current instruction is valid. For example, when the wireless communication module communicates with the main controller, the synchronization header is pre-set to 0X12. Only when the main controller determines that the synchronization header of the received instruction is 0X12, the main controller determines that the instruction is valid, and then parses other contents; the message length is 1BYTE, which is used to characterize the length of the entire instruction; the device type length is 1BYTE, which is used to characterize different types of devices; reserved as reserved bytes, or for padding; the message type identifier length is 1BYTE, which is used to characterize the instruction type. When the issued instruction is an activation instruction, the activation instruction is characterized by pre-established data. For example, the hexadecimal number 0X01 represents the activation instruction. Then when the main controller parses the synchronization header as 0X01, it can confirm that the received instruction is an activation instruction; the message body length is NBYTE, which is used to carry the target activation code and target serial number; the message check code length is 1BYTE, which is used to verify the legality of the instruction.

[0051] In another example, the data format of the response information sent by the wireless communication module to the activation terminal is shown in Table 3:

[0052] Table 3 Among them, the synchronization header length is 1 BYTE, which is used to characterize the instruction type. For example, the instruction type can be divided into function instructions, activation instructions, and lock instructions; the device type length is 1 BYTE, which is used to characterize different types of devices. For example, 0X02 characterizes a smart clothes dryer and 0X03 characterizes a smart door lock; the additional data length is used to characterize the length of the entire instruction; the operation result is used to characterize the operation result of the instruction, such as activation success or failure; the message data length is greater than 12 BYTE and is used to carry specific information; the checksum length is 1 BYTE, which is used for the activation terminal to verify whether the response information is legal and whether the content has been tampered with.

[0053] In an embodiment of the present application, an activation instruction in a preset format is sent to the main controller, so that after parsing the activation instruction in the preset format, the main controller activates the device when it determines that the target activation code is consistent with the stored activation code.

[0054] In an embodiment of the present application, after sending an activation instruction in a preset format to the main controller, the main controller can obtain the target activation code sent by the cloud after parsing the activation box in the preset format according to the preset protocol. If the main controller determines that the target activation code sent by the cloud is consistent with the stored activation code, it means that the device can be activated at present, thereby activating the device.

[0055] The device activation method provided in the embodiment of the present application receives an acquisition request, obtains the target serial number of the main controller from the main controller of the device, and then sends the target serial number to the activation terminal, so that the activation terminal sends the target serial number to the cloud, and the activation terminal sends an activation instruction containing a target activation code to the wireless communication device. After the wireless communication module receives the activation instruction, it first parses the activation instruction, then generates an activation instruction in a preset format, and sends the activation instruction in the preset format to the controller, so that after the main controller receives the activation instruction in the preset format, when it determines that the received target activation code is consistent with the stored activation code, it activates the device. The present application parses and reorganizes the information exchanged between the cloud and the activation terminal through the wireless communication module, thereby ensuring information security during the information interaction process, making it more difficult to crack the transmitted information, effectively avoiding data leakage and interception, preventing brute force cracking of the activation device, and improving the security of the device activation process.

[0056] On the basis of the above embodiments, as an optional embodiment, an activation instruction in a preset format is generated according to the analysis result, and after being sent to the main controller, an activation failure message sent by the main controller is received; if the number of times the activation failure message is received is greater than a first preset number, the activation instruction is stopped from being received within a preset time period, and a suspended activation message is sent to the activation terminal; the suspended activation message is used to indicate that the activation terminal cannot send an activation instruction to the wireless communication module within a preset time period; if the number of times the activation failure message is received is greater than a second preset number, an activation prohibition message is sent to the activation terminal; wherein, the activation failure message is sent when the main controller determines that the target activation code is inconsistent with the stored activation code, and the first preset number is less than the second preset number.

[0057] In the implementation of the present application, if the main controller determines that the target activation code in the received activation instruction of a preset format is inconsistent with the stored activation code, the activation instruction fails to pass the verification and the device cannot be activated. Therefore, the activation failure information is returned to the wireless communication module, so that the wireless communication module receives the activation failure information sent by the main controller, that is, the wireless communication module receives the activation failure information, which indicates that the activation has failed.

[0058] In an embodiment of the present application, after the wireless communication module determines that the activation has failed, it will return a response message of the activation failure to the activation terminal. Usually, after the activation fails, the activation terminal will re-acquire the target activation code from the cloud and then send an activation instruction containing the target activation code to the wireless communication module again. The wireless communication module will parse and reorganize the activation instruction again, generate an activation instruction in a preset format, and then send the activation instruction in the preset format to the main controller. In order to avoid security issues such as illegal activation, the number of activations for each device is limited. Therefore, when the number of activations of the device exceeds the pre-defined limit, the corresponding operation will be performed.

[0059] In an embodiment of the present application, if the wireless communication module determines that the number of times it receives activation failure information sent by the main controller exceeds a first preset number, it means that the current device has been activated too many times and there is a safety hazard. Therefore, the wireless communication module suspends receiving activation instructions sent by the activation terminal within a preset time period, and informs the activation terminal by sending a suspended activation message that the current number of activation failures is too many and that it is prohibited to send activation instructions to the wireless communication module within the preset time period. For example, if the wireless communication module receives activation failure information more than ten times, it stops receiving activation instructions sent by the activation terminal within three minutes, and sends a suspended activation message to the activation terminal, informing the activation terminal that it is prohibited to send activation instructions within three minutes starting from the current moment.

[0060] In an embodiment of the present application, when the activation instruction sent by the activation terminal is suspended for more than a preset time period, the activation instruction is restarted, and the number of activation failure information received is continued to be counted. If the number of subsequent activation failure information received is greater than the second preset number, it means that the current device cannot be activated. Therefore, an activation prohibition message is sent to the activation terminal to instruct the installer of the activation terminal to contact the after-sales staff of the device, so as to solve the problem that the device cannot be activated. For example, based on the above example, after the activation is suspended for three minutes, if the activation failure message is still received subsequently, it is accumulated based on the original ten times of receiving the activation failure message until the number of activation failures received is twenty times, and then an activation prohibition message is sent to the activation terminal to instruct the activation terminal to connect with the relevant staff to solve the problem that the device cannot be activated.

[0061] In the above scheme, the wireless communication module determines whether the device can still be activated based on the number of activation failure information fed back by the main controller. When multiple activation failures occur, the activation is limited for a short time. When the number of activations exceeds the upper limit, the device activation is completely prohibited to avoid large amounts of data attempts to crack the activation through external devices or scripts, thereby protecting the device to be activated and providing higher security.

[0062] Based on the above embodiments, as an optional embodiment, the parsing result is calculated according to a cyclic redundancy check algorithm to obtain a target checksum of the activation instruction; the calculated target checksum is compared with the checksum in the parsing result; if the target checksum is consistent with the checksum in the parsing result, an activation instruction in a preset format is generated according to the parsing result.

[0063] In an embodiment of the present application, when the activation terminal sends an activation instruction to the wireless communication module, the activation instruction will carry a checksum. After the wireless communication module receives the activation instruction, it will also calculate the target checksum based on the received activation instruction. When the calculated target checksum is consistent with the activation checksum carried by the activation instruction, it means that the activation instruction is legal and has not been tampered with, thereby further generating an activation instruction in a preset format that can be parsed by the main controller based on the parsing result, thereby instructing the main controller to activate the device.

[0064] In one example, the wireless communication module parses the activation instruction and obtains the parsing result, which includes: synchronization header, message data and checksum, where the synchronization header is 0x01, the message data is 0xA3, and the CRC register is initialized. The CRC register is a component used to execute the cyclic redundancy check algorithm. For example, it is set to 0xFFFF, and each byte of the synchronization header and message data is gradually input into the CRC register to execute each step of the RC algorithm. The CRC algorithm generally includes the following steps: Shift and XOR Operations: The processing of each byte consists of XORing the byte with the current value in the CRC register, followed by shifts and other bit operations as dictated by the algorithm.

[0065] Calculate the final CRC value: After all bytes are processed, the final CRC value, that is, the target checksum, is obtained. When the target checksum is consistent with the checksum carried by the instruction, it can be determined that the instruction received by the wireless communication module maintains integrity and correctness during the transmission process.

[0066] In the above scheme, when receiving the activation instruction, the activation instruction is first parsed to obtain the parsing result. According to the parsing result, the target checksum can be calculated, and the checksum sent by the activation terminal can also be obtained. When the target checksum and the checksum sent are consistent, it means that the current activation instruction has not been tampered with during the transmission process. Therefore, the activation instruction in a preset format is generated according to the parsing result obtained by parsing the activation instruction, which prevents the execution of unauthorized instructions and ensures the legal activation of the device.

[0067] On the basis of the above embodiments, as an optional embodiment, before responding to the acquisition request sent by the activation terminal, if it is detected that the device is powered on, a device status acquisition request is sent to the main controller; the device status sent by the main controller is received, and a broadcast message containing the device status and the device identification is broadcast, so that after the activation terminal scans the broadcast information, if it is determined that the device is in an unactivated state according to the device status, the device identification of the device is displayed.

[0068] In an embodiment of the present application, before receiving the acquisition request sent by the activation terminal, the wireless communication module will also broadcast the device status of the device. Therefore, after detecting that the device is powered on, the wireless communication module first sends a device status acquisition request to the main controller. After receiving the device status acquisition request, the main controller sends the device status of the device to the wireless communication module. After receiving the device status, the wireless communication module will add the device status to the broadcast information for broadcasting. There are four types of device status: activated, unconfigured and unbound, activated, networked and bound, inactivated and locally bound. Each device status has a corresponding Bluetooth broadcast flag. The device status is represented by the Bluetooth broadcast flag in the broadcast information. For example, the Bluetooth broadcast flag corresponding to activated, unconfigured and unbound is FFE3050500, the Bluetooth broadcast flag corresponding to activated, networked and bound is FFE3050501, the Bluetooth binding flag corresponding to inactivated is FFE3050502, and the Bluetooth binding flag corresponding to locally bound is FFE3050504.

[0069] In an embodiment of the present application, the wireless communication module broadcasts broadcast information carrying the device status so that after the activation terminal scans the broadcast information, it can determine whether the currently scanned device needs to be activated based on the device status carried in the broadcast information. When it is determined that the Bluetooth broadcast flag representing the device status in the broadcast information indicates that it is not activated, it means that the currently scanned device needs to be activated. Therefore, the device identification of the device is displayed on the visual interface of the activation terminal. The device identification can be the Mac address of the device. By triggering the control corresponding to the device identification, a Bluetooth connection with the device corresponding to the device identification can be established, so that the activation terminal can send a request to the wireless communication module to further determine the identity of the device.

[0070] In the above scheme, when it is detected that the device is powered on, the wireless sends a device status acquisition request to the main controller to obtain the device status. After obtaining the device status, it starts broadcasting broadcast information containing the device status, so that when the device is not activated, it can be scanned by the activation terminal in time, so that it can be selected for Bluetooth connection, thereby performing the activation operation.

[0071] On the basis of the above embodiments, as an optional embodiment, after sending the target serial number to the activation terminal, a confirmation device instruction sent by the activation terminal is received; the confirmation device instruction is sent by the activation terminal after determining that the target serial number of the main controller is stored in the cloud; after parsing the confirmation device instruction, a confirmation device instruction in a preset format is generated according to the parsing result; a confirmation device instruction in a preset format is sent to the main controller, so that after the main controller parses the confirmation device instruction in the preset format, a preset sound is broadcast according to the confirmation device instruction; the preset sound is used to indicate the device to which the activation terminal is connected.

[0072] In an embodiment of the present application, after the wireless communication module sends the target serial number to the activation terminal, the activation terminal will send the target serial number to the cloud. The cloud will determine whether the target serial number is stored. After determining that the target serial number is stored, it will send a confirmation device instruction to the activation terminal. The activation terminal sends the confirmation device instruction to the wireless communication module. Since the main controller can only parse information in a preset format, the wireless communication module will first parse the confirmation device instruction, and then generate a confirmation device instruction in a preset format based on the parsing result, and then send the confirmation device instruction in a preset format to the main controller. After receiving the confirmation device instruction in the preset format, the main controller will parse the confirmation device instruction and broadcast a preset sound based on the parsing result. For example, the device broadcasts a beeping sound, so that the installer can confirm whether the currently connected device is the same device as the device planned to be activated.

[0073] In the above scheme, in order to actually establish the consistency between the device connected by wireless communication and the device to be activated, the device instructions are received, parsed and reorganized to confirm, and a device confirmation instruction in a preset format is sent to the main controller to instruct the connected wireless communication device to broadcast a preset sound. When the connected device broadcasts the preset sound, the installer can confirm that the currently connected device and the device to be activated are the same device. The above scheme ensures the consistency between the actually activated device and the device to be activated during the activation process.
