[0049] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of the embodiment of the present application is: the cloud system generates a unique serial number tag and dynamic key for each smart device, and distributes the serial number tag and dynamic key to the application end. The communication module obtains the serial number tag and dynamic key sent by the application end, logs in to the Internet of Things message middleware through the message queue telemetry transmission protocol, and generates a login request based on the serial number tag and dynamic key; the Internet of Things message middleware forwards the login request to the cloud system for authentication, and obtains the instruction template issued by the cloud system according to the authentication result; the communication reads the smart device data according to the instruction template, and reports the smart device data to the cloud system, so that the cloud system can form a smart device management chain based on the smart device data.

[0052] The embodiments of the present application take into account that in the Internet of Things (IoT) applications, the management and data collection of smart devices usually rely on complex configuration and authentication processes. At present, most smart devices directly burn the key and serial number (SN) label into the device when they leave the factory. This practice leads to a series of problems: complex production process: before the device is produced, the key and SN label must be generated in the cloud and exported to the device manufacturer, which increases the complexity and time cost of the production process; high consistency requirements: the burned SN label must be consistent with the SN label attached to the outside of the device, requiring a high degree of consistency during the production process, increasing the risk of error; risk of authentication failure: when the device is networked or connected, the burned SN and key are usually used directly for cloud authentication. If the attached SN label is inconsistent with the burned SN label, the connection will fail, resulting in the device being unable to be used normally; key update is difficult: the burned key cannot usually be updated. If the background data is leaked, it will cause serious security risks and affect the security and reliability of the device. In summary, most smart devices directly burn the key and serial number (SN) label into the smart device when they leave the factory, thereby meeting the basic connection and authentication requirements of smart devices to a certain extent. However, burning the key and serial number (SN) tag directly into the device significantly increases the complexity of the production process and requires a high degree of consistency in the production process, which significantly increases the risk of errors in the production process of smart devices and the risk of failure in the authentication process. In addition, once the burned key is leaked or cracked, it will pose a serious threat to the security of smart devices.

[0053] Therefore, the present application provides a solution, wherein the communication module obtains the serial number tag and dynamic key generated and sent by the cloud system; the cloud system generates and sends the serial number tag and dynamic key to the application end, avoiding the complicated process of burning the key and SN into the device before the device is produced, thereby improving production efficiency; the communication module logs in to the Internet of Things Message Middleware (EMQX) through the Message Queue Telemetry Transmission (MQTT) protocol, and generates a login request based on the serial number tag and dynamic key; the Internet of Things Message Middleware (EMQX) forwards the login request of the communication module to the cloud system for authentication, and obtains the instruction template issued by the cloud system based on the authentication result: the cloud system is responsible for authentication and instruction issuance to ensure the speed and efficiency of device connection; the communication module reads the smart device data according to the instruction template, and reports the smart device data to the cloud system, so that the cloud system can form a smart device management chain based on the smart device data: the complete device management chain helps to realize the full life cycle management of the device and improve the reliability and availability of the device. In summary, the cloud system is responsible for dynamically generating and distributing serial number tags and keys, performing secure dynamic authentication, generating a smart device management chain, and realizing unified cloud management. Unified cloud management reduces inconsistencies between devices and improves the stability of device operation; by dynamically generating and distributing serial number tags and keys, the authentication failure error rate caused by inconsistencies between serial number tags and burning information during the production of smart devices is reduced, thereby achieving fast and efficient connection of smart devices and ensuring the security and reliability of smart device connections.

[0054] It should be noted that in the present application, the communication module and the cloud system communicate and exchange data through the IoT message middleware, and the communication module serves as a connecting bridge between the cloud system and smart devices, enabling smart devices with different communication protocols and standards to effectively interact with the cloud system, thereby realizing the management of smart devices by the cloud system through the smart device management chain.

[0055] Based on this, the embodiment of the present application provides a smart device management method, which is applied to the communication module, referring to Figure 1 , Figure 1 A flowchart of the first embodiment of the smart device management method provided in the present application.

[0056] In this embodiment, the smart device management method includes steps S10 to S40:

[0057] Step S10, obtaining the serial number tag and dynamic key generated and sent by the cloud system for the smart device;

[0058] The serial number tag is a unique identifier for smart devices, used to distinguish different smart devices or software instances. In the Internet of Things (IoT) environment, the serial number tag is used to ensure the uniqueness of the identity of smart devices for easy tracking and management. Dynamic keys are encryption keys that change over time and are used to enhance the security of communications.

[0059] Specifically, the cloud system will generate a unique serial number tag for each device based on the registration information or production information of the smart device. This serial number tag is assigned when the smart device is first connected to the cloud system and stored in the database of the cloud system. The cloud system will generate a dynamic key for each smart device based on a certain algorithm or rule, and the dynamic key will be changed regularly.

[0060] The application side is the interface for users to interact with the cloud system. It is responsible for receiving user instructions, sending requests to the cloud system, and displaying the data returned by the cloud system. Specifically, the cloud system sends the serial number tag and dynamic key to the application side, and the application side sends the serial number tag and dynamic key to the communication module.

[0061] Step S20, generating a login request according to the serial number tag and the dynamic key, and logging into the Internet of Things message middleware through the login request and the message queue telemetry transmission protocol, and forwarding the login request to the cloud system for authentication through the Internet of Things message middleware;

[0062] Message Queuing Telemetry Transport (MQTT) is a lightweight, publish / subscribe-based messaging protocol designed for IoT environments, allowing smart devices to transmit messages reliably with minimal resource consumption and limited bandwidth.

[0063] IoT message middleware, namely EMQX message server, EMQX (Erlang MQTT Broker eXtended) is a high-performance, scalable open source MQTT message broker or message server, specially designed for IoT (IoT) communication. In IoT, devices need to frequently exchange data and information, and EMQX is the key component to undertake this task.

[0064] The purpose of the login request is to prove the legitimacy and identity of the device to the cloud system. The login request contains the serial number tag and dynamic key. The login request is sent to the cloud system through the IoT message middleware. The request contains necessary information such as the serial number tag and dynamic key of the smart device. After receiving the login request, the cloud system verifies the identity information in the request. This usually involves comparing it with the device information database stored in the cloud system.

[0065] Step S30, obtaining the instruction template issued by the cloud system according to the result of the authentication;

[0066] Based on the authentication result, the cloud system decides whether to allow the device to access resources or perform operations. If the authentication is successful, the cloud system generates a corresponding instruction template based on predefined rules. The cloud system sends the generated instruction template to the communication module through the IoT message middleware, and the communication module performs the corresponding operation or processing according to the instruction template.

[0067] Step S40, reading the smart device data according to the instruction template, and reporting the smart device data to the cloud system, so that the cloud system forms a smart device management chain based on the smart device data to manage the smart device.

[0068] Instruction templates are usually pre-defined by the cloud system based on specific business requirements or operation logic. These templates contain key information such as the operations that the device should perform, the data reading format, and the reporting cycle or conditions. According to the requirements in the instruction template, the corresponding data is read, and the communication module reports the read data to the cloud system. The reported data may include raw data, pre-processed data, or a combination of the two. The reporting process usually involves data encapsulation, encryption, and compliance with transmission protocols to ensure data integrity and security.

[0069] After receiving the data reported by the smart device, the cloud system will perform a series of processing and analysis. These processes may include data decoding, verification, storage and further analysis (such as data mining, machine learning, etc.). Based on this data, the cloud system can form a comprehensive management chain for smart devices, including device status monitoring, fault warning, performance evaluation and optimization suggestions.

[0070] In addition, consider introducing a multi-user access control model. Through the Merkle hash tree mechanism, multiple users can safely and efficiently obtain the key material of the hierarchical nodes through independent hash chains, thereby achieving effective management of massive data resources.

[0071] The present embodiment provides a smart device management method, which is applied to a communication module, wherein the communication module obtains a serial number tag and a dynamic key generated and sent by a cloud system; the cloud system generates and sends the serial number tag and the dynamic key to the application end, avoiding the complex process of burning the key and SN into the device before the device is produced, thereby improving production efficiency; the communication module logs in to the Internet of Things Message Middleware (EMQX) through the Message Queue Telemetry Transmission (MQTT) protocol, and generates a login request according to the serial number tag and the dynamic key; the Internet of Things Message Middleware (EMQX) forwards the login request of the communication module to the cloud system for authentication, and obtains the instruction template issued by the cloud system according to the authentication result: the cloud system is responsible for authentication and instruction issuance to ensure the rapidity and efficiency of device connection; the communication module reads the smart device data according to the instruction template, and reports the smart device data to the cloud system, so that the cloud system can form a smart device management chain based on the smart device data: the complete device management chain helps to realize the full life cycle management of the device and improve the reliability and availability of the device. In summary, the cloud system is responsible for dynamically generating and distributing serial number tags and keys, performing secure dynamic authentication, generating a smart device management chain, and realizing unified cloud management. Unified cloud management reduces inconsistencies between devices and improves the stability of device operation; by dynamically generating and distributing serial number tags and keys, the authentication failure error rate caused by inconsistencies between serial number tags and burning information during the production of smart devices is reduced, thereby achieving fast and efficient connection of smart devices and ensuring the security and reliability of smart device connections.

[0072] In a feasible implementation, step S20 may include steps S21 to S22:

[0073] Step S21, using the serial number tag as the login name and the dynamic key as the login password, and forming a login request according to the login name and the login password.

[0074] Each smart device has a unique serial number tag (SN) and dynamic key in the cloud system. SN is the unique identifier of the smart device, which is used to identify the device in the cloud system. The dynamic key is generated by the cloud for the device and is used to authenticate the device during the connection and communication process to ensure the security of communication. In the login request, the communication module uses the device's SN as the username and the dynamic key as the password.

[0075] The advantage of this is that even if the device is deployed in a different network environment after leaving the factory, as long as it can connect to the cloud and obtain the latest dynamic key, it can successfully log in to the message middleware. After EMQX receives the MQTT login request from the communication module, it forwards the request to the cloud for authentication. The cloud intercepts the SN from the user name and compares it with the password (key). After successful verification, the device is marked as online.

[0076] Step S22, logging into the Internet of Things message middleware through the login request and the message queue telemetry transmission protocol;

[0077] The communication module attempts to log in to EMQX using the MQTT protocol. The login process involves establishing a TCP connection with EMQX and sending a login request in accordance with the provisions of the MQTT protocol.

[0078] In a feasible implementation, step S40 may include steps S41 to S42:

[0079] Step S41, communicating with the smart device through the serial port according to the instruction template to read the smart device data;

[0080] The instruction template is formulated by the cloud system according to specific needs, and is used to instruct the communication module on how to read data from smart devices. After receiving the instruction template, the communication module will use the serial port communication interface to communicate with the smart device. Serial port communication is a common data transmission method, especially suitable for short-distance, low-speed communication scenarios.

[0081] According to the instruction template, the communication module will send specific instructions to the smart device through the serial port, and then receive the data returned by the smart device. This data may include device status information, sensor readings, etc.

[0082] Step S42: reporting the smart device data to the cloud system via the message queue telemetry transmission protocol.

[0083] After reading the data from the smart device, the communication module will report the data to the cloud system through the MQTT protocol. This is usually achieved by sending a message to a specific topic subscribed to the cloud (such as / receive / communication module device ID).

[0084] After receiving the data reported by the communication module, the cloud system will parse and process it. On the one hand, the cloud will parse the data packet to obtain the unique identification code and other relevant data of the smart device; on the other hand, the cloud will associate the device ID of the communication module, the SN (serial number) of the smart device, the unique identification code, etc., to form a complete device management chain.

[0085] The present application also provides a smart device management method, which is applied to a cloud system. Figure 2 , Figure 2 A flowchart of a second embodiment of the smart device management method provided in this application. The method includes steps A10 to A30:

[0086] Step A10, generating a serial number tag and a dynamic key for the smart device, and sending the serial number tag and the dynamic key to the communication module;

[0087] In the cloud system, a unique serial number label (SN) and a dynamic key are generated for each smart device that is about to leave the factory. The SN is usually printed and affixed to the outside of the device for easy identification and management. The dynamic key is not burned into the device, but stored in the cloud database, waiting for the subsequent device connection and authentication process.

[0088] The cloud system sends the generated SN and dynamic key to a dedicated application terminal (usually a mobile phone APP or similar client software) through a secure method (such as HTTPS protocol), and then sends the SN and dynamic key to the communication module via Bluetooth, Wi-Fi (such as softAP mode) or other communication methods.

[0089] Step A20, receiving a login request, performing authentication according to the login request, and issuing an instruction template to the communication module according to the result of the authentication, wherein the login request is generated by the communication module according to the serial number tag and the dynamic key, and is forwarded by logging into the Internet of Things message middleware through the message queue telemetry transmission protocol;

[0090] The communication module uses the SN received from the APP as the login name and the dynamic key as the login password to form an MQTT login request. The communication module uses the SN received from the APP as the login name and the dynamic key as the login password to form an MQTT login request. The cloud intercepts information from the user name (ie, SN) and compares it with the password (ie, dynamic key) for authentication. According to the authentication result, an instruction template is sent to the communication module, which is used to instruct the communication module on how to read data from the smart device.

[0091] Step A30, receiving smart device data, and forming a smart device management chain based on the smart device data to manage the smart device, wherein the smart device data is read and reported by the communication module according to the instruction template.

[0092] The communication module communicates with the smart device through the serial port according to the Modbus command template issued by the cloud. The communication module reads the data of the smart device and reports the read data to the cloud through the MQTT protocol. The cloud receives the smart device data reported by the communication module by subscribing to a specific topic (such as / receive / communication module device ID) and forms a smart device management chain based on the smart device data.

[0093] Specifically, in another feasible implementation of step A30, a key tree can be constructed based on the serial number tag. In the key tree, the center of gravity of the tree is selected as the starting point for key derivation, and the key of each smart device is derived by using the characteristics of the center of gravity node (such as its central position in the tree structure, which can minimize the propagation range of key updates). In this way, the distribution and update of keys can be ensured to be more efficient and secure.

[0094] Furthermore, the derived key is used to encrypt the smart device data, and then the encrypted smart device data is reported to the cloud system. After receiving the encrypted data, the cloud system uses the corresponding key to decrypt it, and forms a smart device management chain based on the decrypted smart device data.

[0095] This embodiment provides a smart device management method, which is applied to the cloud system. The cloud system generates a unique serial number tag (SN) and a dynamic key for each smart device to ensure the uniqueness of the identity and the security of communication of the smart device; the introduction of dynamic keys increases the difficulty of cracking communications, thereby protecting smart devices from unauthorized access and data leakage; the message queue telemetry transmission protocol (MQTT) is used to log in to the Internet of Things message middleware for forwarding, and the serial number tag and dynamic key are used for authentication, ensuring that only legal devices can access the cloud system; the instruction template sent by the cloud to the communication module simplifies the device configuration process, and there is no need to manually set the instructions for reading data, and the operation is performed directly according to the instruction template. Improve the efficiency of device connection and data reading. Through the formed smart device management chain, the entire life cycle of the device can be tracked, and the smart device can be quickly and efficiently connected, and the security and reliability of the smart device connection can be ensured.

[0096] Based on the second embodiment of the present application, the third embodiment of the present application is proposed. In the third embodiment of the present application, the same or similar contents as those of the above-mentioned second embodiment can be referred to the above introduction, and will not be repeated in the following.

[0097] In this embodiment, step A20 of receiving a login request, performing authentication according to the login request, and issuing an instruction template to the communication module according to the authentication result may include steps A21 to A23:

[0098] Step A21, receiving a login request, and extracting a serial number from a login name included in the login request;

[0099] When the communication module attempts to log in to the EMQX service through the MQTT protocol, it will send a login request to the cloud. This login request contains the necessary authentication information, including the login name and password (in this scenario, the password is actually a dynamic key). After receiving the login request, the cloud server will parse the serial number from the login name.

[0100] Step A22, using the serial number as a reference, comparing it with the dynamic key stored in the cloud database;

[0101] The cloud server uses the serial number parsed from the login name as a query condition to query the dynamic key corresponding to the serial number stored in the cloud database. The cloud server compares the queried dynamic key with the password (i.e., dynamic key) provided in the login request.

[0102] Step A23, if the serial number is successfully compared with the dynamic key stored in the cloud database, a command template is sent to the communication module according to the pre-acquired device ID, and the smart device is marked as online.

[0103] If the serial number is successfully matched with the dynamic key stored in the cloud database, it means that the identity of the communication module has been verified. The cloud server will send a command template to the communication module based on the device ID of the successfully verified communication module obtained in advance. This command template is usually used to instruct the communication module on how to interact with the smart device.

[0104] The cloud server will also mark the smart device as online, indicating that the device has been successfully connected to the cloud and can perform subsequent data collection and management.

[0105] In this embodiment, the serial number is intercepted from the login request and compared with the dynamic key stored in the cloud database. The use of dynamic keys means that even if the key of the device changes after leaving the factory, there is no need to re-burn the device, which improves the flexibility and security of device deployment. The serial number is used as a unique identifier of the device identity, and the combination of the dynamic key can ensure that only legitimate devices can successfully log in and perform subsequent data interaction. This avoids the access of illegal devices and ensures the purity of the device network and the security of the data. Real-time data verification and comparison through the cloud avoids authentication failures caused by inconsistent device information. This reduces the error rate and ensures that the device can be put into operation efficiently and safely.

[0106] Based on the above embodiments of the present application, a fourth embodiment of the present application is proposed. In the fourth embodiment of the present application, the same or similar contents as those of the above embodiments can be referred to the above introduction, and will not be described in detail later.

[0107] In this embodiment, step A30 of receiving smart device data and managing the smart device by forming a smart device management chain based on the smart device data may include steps A31 to A32:

[0108] Step A31, receiving and parsing the smart device data read and reported by the communication module according to the instruction template, and obtaining a unique identification code of the smart device;

[0109] The cloud system is responsible for receiving the smart device data reported by the communication module. This data is usually uploaded by the communication module after reading the information of the smart device through communication methods such as the MQTT protocol.

[0110] After receiving the data from the smart devices, the cloud will parse it to extract the unique identification code of the smart device (usually denoted as SN2 to distinguish it from the SN label attached to the outside of the device mentioned above) from the data packet.

[0111] This unique identification code is an inherent attribute of the smart device and is used to uniquely identify the device in the cloud system. Obtaining this identification code by parsing the data packet is an important prerequisite for establishing a device management chain.

[0112] Step A32, associating the pre-stored corresponding relationship with the unique identification code to form a smart device management chain to manage the smart device.

[0113] In the cloud system, the corresponding relationship between the communication module device ID and the SN label attached to the outside of the device is pre-established through steps such as associating the cloud cache device ID with the SN and sending the SN and the key to the communication module.

[0114] The cloud will match and associate the parsed smart device unique identification code (SN2) with the established correspondence. The purpose of this step is to bind the data of the smart device with its identity information in the cloud system (including the communication module device ID and SN tag), thereby forming a complete smart device management chain.

[0115] In this embodiment, by using dynamic keys for identity authentication instead of fixed keys pre-burned in the device, the security of device connection is greatly enhanced. The intelligent device management chain makes device management more efficient and unified, and is suitable for the deployment and management of large-scale IoT devices. Through the intelligent device management chain, the cloud can monitor the status of the device in real time, and issue instructions and collect data as needed, which improves the efficiency and accuracy of device management.

[0116] Based on the above embodiments of the present application, a fifth embodiment of the present application is proposed. In the fifth embodiment of the present application, the same or similar contents as those of the above embodiments can be referred to the above introduction, and will not be repeated in the following.

[0117] On this basis, please refer to Figure 3 , Figure 3 A flowchart of the fifth embodiment of the smart device management method of the present application is provided.

[0118] In this embodiment, before step A21 of receiving a login request and extracting a serial number from a login name included in the login request, steps A121 to A123 are also included:

[0119] Step A121, storing the dynamic key in a cloud database;

[0120] The cloud system is responsible for securely storing the generated dynamic key in the cloud database, which is usually encrypted and strictly access-controlled to ensure the security and confidentiality of the dynamic key. The purpose of storing the dynamic key is to verify it in the subsequent authentication process to ensure that only legitimate devices can access the system.

[0121] Specifically, dynamic keys are usually encrypted before storage to prevent unauthorized access and data leakage. In addition, cloud databases should set strict access control policies so that only authorized users or system components can access and modify dynamic keys. To further improve security, dynamic keys may need to be updated regularly. This usually involves generating new keys and replacing old keys. To further improve security, dynamic keys may need to be updated regularly. This usually involves generating new keys and replacing old keys.

[0122] Step A122, obtaining the device ID of the communication module read by the application end;

[0123] The application (such as a mobile phone APP) is responsible for reading the device ID of the communication module and sending it to the cloud system. The device ID is the unique identifier of the communication module and is used to identify and track the device in the cloud system.

[0124] Specifically, the application establishes a connection with the communication module through Bluetooth, Wi-Fi or other communication protocols and reads its device ID. The application establishes a connection with the communication module through Bluetooth, Wi-Fi or other communication protocols and reads its device ID. After receiving the device ID, the cloud system may perform certain verification operations to ensure the accuracy and integrity of the data.

[0125] Step A123, establishing a corresponding relationship between the device ID and the serial number tag, and storing the corresponding relationship in a cloud database.

[0126] The cloud system is responsible for establishing the correspondence between the device ID and the serial number tag and storing this relationship in the database. This correspondence is the basis for subsequent device management and data tracking.

[0127] The cloud system is responsible for establishing the correspondence between the device ID and the serial number tag, and storing this relationship in the database. This correspondence is the basis for subsequent device management and data tracking. The cloud system is responsible for establishing the correspondence between the device ID and the serial number tag, and storing this relationship in the database. This correspondence is the basis for subsequent device management and data tracking. If the device ID or serial number tag changes (such as device replacement, serial number update, etc.), the cloud system should promptly update the correspondence in the database to ensure the accuracy and consistency of the data.

[0128] In this embodiment, by securely storing the dynamic key in the cloud database, the key can be prevented from being obtained by unauthorized users or systems, thereby protecting the smart device from malicious attacks and data leakage risks. Storing dynamic keys also provides the necessary conditions for the subsequent device authentication process. When a smart device attempts to connect to the cloud, the cloud can confirm its identity by verifying the dynamic key provided by the device, thereby ensuring that only legitimate devices can access the system. By establishing a correspondence between the device ID and the serial number tag, the cloud can achieve comprehensive management and tracking of smart devices. This helps to promptly detect and handle device failures, optimize device configuration, and improve device efficiency.

[0129] The following will be combined Figure 4 The complete process of the intelligent device management method of this application is described in detail, among which: Figure 4 A flowchart of the smart device management method provided for this application.

[0130] First, in the cloud system, a unique SN (serial number) and key are generated for each smart device that is about to leave the factory. The SN label is printed and affixed to the outside of the device, while the key is not burned into the device, but stored in the cloud database, waiting for the subsequent device connection and authentication process.

[0131] Furthermore, the APP quickly connects to the communication module via Bluetooth or softAP to obtain the device ID of the communication module. This connection process is simple and efficient, and the user operation is convenient. Through the APP to scan the SN label on the smart device or manually enter the SN, the APP calls the cloud interface to obtain the key corresponding to the SN, ensuring real-time acquisition of the key instead of pre-burning, reducing production complexity and improving security.

[0132] Furthermore, the device ID and SN of the communication module are sent to the cloud, and the cloud caches the relationship between the two to provide a basis for subsequent communication. The cloud performs real-time data verification to avoid using factory-fixed keys and enhance security.

[0133] Furthermore, the APP securely sends the SN and key to the communication module via TCP or UDP protocol via Bluetooth or softAP to ensure the security and integrity of the data during transmission. The communication module uses the MQTT protocol to log in to EMQX, and the login username is set to the device's SN (device_sn), and the password is the key provided by the cloud. This solution enhances the security of communication through dynamic key authentication.

[0134] Furthermore, after receiving the login request, it is forwarded to the cloud for authentication. The cloud intercepts the SN from the user name, verifies the correctness of the SN and the key, and marks the device as online. At this time, the cloud sends a Modbus instruction template through a custom MQTT topic ( / pub / communication module device ID) for interaction with the smart device.

[0135] Finally, after receiving the Modbus instruction template, the communication module conducts efficient and secure data interaction with the smart device through the serial port, reads the data of the smart device according to the template instruction set, and reports it to the cloud through the MQTT protocol. The cloud subscribes to a specific topic ( / receive / communication module device ID) to obtain the smart device data reported by the communication module, parses the data packet and obtains the unique identification code (SN2) of the device. The cloud associates the communication module device ID, the unique identification code SN2 of the smart device, and SN to form a complete device management chain.

[0137] The data acquisition module 10 is used to acquire the serial number tag and dynamic key generated and sent by the cloud system for the smart device;

[0139] The device management chain generation module 30 is used to obtain the instruction template issued by the cloud system according to the authentication result, read the smart device data according to the instruction template, and report the smart device data to the cloud system so that the cloud system can form a smart device management chain based on the smart device data to manage the smart device.
