This ensures unified management and timely distribution of switching information, eliminating the need for the IoT device to generate or query addresses itself.

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] In the description of this application, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "third," etc., may explicitly or implicitly include one or more features.

[0019] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0020] It should be noted that since the method in this application embodiment is executed in a computer device, the processing objects of each computer device exist in the form of data or information, such as time, which is essentially time information. It is understood that if size, quantity, position, etc. are mentioned in subsequent embodiments, they are all corresponding data that exist so that the computer device can process them. Specific details will not be elaborated here.

[0021] like Figure 1 As shown, an application scenario of one embodiment of the present invention includes a cloud server 100, an IoT device 200, and a user device 300. The user device 300 is communicatively connected to the cloud server 100, and the cloud server 100 is communicatively connected to the IoT device 200.

[0022] Specifically, when a user needs to switch the cloud address of IoT device 200, the user can perform a cloud connection switching operation in the application interface of user device 300 and send the cloud connection switching operation to cloud server 100. Then, cloud server 100 generates cloud connection information based on the cloud connection switching operation and sends the cloud connection information to IoT device 200, so that IoT device 200 switches to the target cloud server address based on the cloud connection information.

[0023] User equipment 300 can be an electronic device such as a mobile phone, laptop, or tablet computer that can communicate with cloud server 100. It provides an application interface, receives user connection switching operations, and sends the connection switching operations to cloud server 100. Internet of Things (IoT) device 200 can be a smart device such as a smart air conditioner, smart washing machine, or smart TV that can communicate with cloud server 100. It receives connection information and switches to the target cloud server address based on the connection information.

[0024] like Figure 2 As shown, this application embodiment provides a cloud address switching method applied to a cloud server. The cloud server can be cloud server 100 in the above application scenario, or other cloud servers capable of executing the cloud address switching method. The cloud address switching method includes the following steps S110 and S120: Step S110: Obtain cloud connection information. Cloud connection information includes the target cloud server address that the IoT device needs to switch to.

[0025] The cloud connection information is a collection of necessary data related to IoT devices connecting to the cloud, primarily used to guide IoT devices in switching their cloud connection addresses. This information includes the target cloud server address the IoT device needs to switch to, and the communication protocol type of the target cloud server. For example, the target cloud server address could be "http: / / 192.168.1.5 / register" or "http: / / 192.168.1.5 / login". The communication protocol type of the target cloud server could be a protocol such as MQTT.

[0026] Specifically, cloud information can be generated by receiving configuration files from external systems, such as batch configuration files uploaded to cloud servers by operations and maintenance personnel through a management platform; or, cloud information can be obtained by user devices connected to other cloud servers uploading cloud-related data.

[0027] In practical applications, the process of obtaining cloud connection information can be implemented using timed polling, such as checking for new cloud connection tasks at preset time intervals, or receiving real-time pushed cloud connection task information by subscribing to a message queue. As a preferred implementation, obtaining cloud connection information can also be triggered by listening to specific events, such as automatically obtaining the corresponding cloud connection information when a cloud platform migration completion event or a network policy change event is detected.

[0028] In some embodiments, step S110, obtaining cloud connection information, includes: receiving a cloud connection switching operation sent by a user equipment; and generating cloud connection information based on the cloud connection switching operation.

[0029] Among them, the cloud switching operation refers to the operation command initiated by the user through the user device to trigger the switching of the cloud server address.

[0030] Specifically, the cloud connection switching operation can be implemented through an interactive entry point provided by the application interface on the user's device. For example, the user selects the target cloud server address in the application and confirms the submission, thereby generating the cloud connection switching operation. The purpose of this cloud connection switching operation is to enable users to remotely and proactively trigger the switching request, avoiding reliance on on-site manual intervention or firmware upgrades, thus adapting to the needs of dynamic scenarios.

[0031] Specifically, the way to generate connection information based on the connection switching operation can be by parsing the content of the connection switching operation and filling it into a preset template, or by calling the cloud configuration interface to generate it in real time.

[0032] In this embodiment, by receiving the cloud connection switching operation sent by the user equipment and generating cloud connection information based on it, the problem of low information acquisition efficiency during cloud address switching is solved. First, the cloud connection switching operation sent by the user equipment serves as a trigger condition, eliminating reliance on local firmware upgrades or manual on-site configuration during the switching process, thus improving switching response speed. Second, the process of generating cloud connection information based on the cloud connection switching operation enables dynamic adjustment of the target cloud server address, supporting rapid switching of batch devices. Through the above technical solution, the process of acquiring cloud connection information is automated and efficient, significantly improving the overall efficiency of cloud address switching.

[0033] Step S120: Send cloud connection information to the IoT device so that the IoT device switches to the target cloud server address based on the cloud connection information.

[0034] Specifically, the process of sending cloud connection information to IoT devices can be implemented using various communication protocols, such as message push mechanisms based on the MQTT (Message Queuing Telemetry Transport) protocol, or RESTful API calls via the HTTP (Hypertext Transfer Protocol) protocol. Cloud connection information can be sent continuously through a long-lived connection or immediately upon detecting an IoT device coming online. This ensures that cloud connection information is transmitted to IoT devices in a timely and accurate manner.

[0035] In some embodiments, step S120 above, which involves sending cloud connection information to an IoT device, includes: obtaining the communication status between the IoT device and the cloud server; if the communication status is online, sending cloud connection information to the IoT device; if the communication status is offline, sending cloud connection information to the IoT device upon receiving a cloud connection request instruction from the IoT device.

[0036] The communication status between IoT devices and cloud servers refers to the real-time connection status between the IoT devices and the cloud servers. This can be achieved through heartbeat detection mechanisms, network status query protocols, or proactive reporting by the devices. An "online" communication status means that the IoT devices and cloud servers are connected. An "offline" communication status means that the IoT devices and cloud servers are not connected.

[0037] Among them, the Lianyun request instruction is a request signal initiated by an IoT device to the cloud server when it changes from an offline state to an online state. Its purpose is to notify the cloud server that the device has the ability to receive information and to send a signal to request Lianyun information.

[0038] In this embodiment, the cloud server monitors the communication status between the IoT device and the cloud server in real time. When the IoT device is online, the cloud server immediately and proactively sends a connection message, thereby shortening the switching response time and improving operational efficiency. When the IoT device is offline, the cloud server waits for the IoT device to come online and triggers the sending of a connection message through a connection request command. This mechanism can adapt to the intermittent connection characteristics of IoT devices and ensures that the connection message is transmitted only when the device can receive it. Furthermore, by combining the two modes of immediate sending in online status and delayed sending in offline status, the overall switching process is more flexible and reliable.

[0039] In some embodiments, after performing step S120 and sending the connection information to the IoT device, the connection address switching method further includes: obtaining the switching result returned by the IoT device; and updating the switching record of the IoT device based on the switching result.

[0040] The switching result serves as a marker indicating the effectiveness of the IoT device's cloud address switching operation, generating a success or failure status value through logical judgment. The switching result includes successful and failed cloud address switching. In some embodiments, the switching result may also include information such as the IoT device's current cloud address and current cloud type.

[0041] Specifically, obtaining the switching results returned by IoT devices refers to receiving status data fed back by IoT devices through communication protocols, which can be achieved using HTTP responses, MQTT message acknowledgments, or custom protocol formats.

[0042] Specifically, updating the switching records of IoT devices based on the switching results can be achieved by writing the received switching status information into a database or log system. This can be done through relational database operations, NoSQL storage, or distributed log systems, aiming to dynamically maintain the historical switching data of the devices and provide a reliable basis for subsequent operation and maintenance.

[0043] In practical applications, users can send a request to the cloud server through their user devices to view the switching records of IoT devices. After receiving the request, the cloud server will send the switching records of IoT devices to the user devices, so that users can obtain the switching records of IoT devices at any time to determine the cloud connection status of IoT devices.

[0044] In this embodiment, the cloud server relies on the actual response data of IoT devices to obtain handover results, rather than based on preset assumptions or external speculation, thereby effectively identifying abnormal scenarios such as communication interruptions and device failures. Simultaneously, updating the handover record based on the obtained handover results not only ensures that the recorded content is synchronized with the actual state of the IoT devices but also provides accurate data support for subsequent fault analysis and batch management decisions. In summary, the cloud server can dynamically track the handover behavior of IoT devices and promptly detect handover failures, thereby optimizing overall operational efficiency.

[0045] In summary, this application provides a cloud address switching method applied to a cloud server. The cloud server actively acquires and sends target cloud server address information, enabling IoT devices to automatically complete address switching. In the cloud information acquisition stage, the cloud server centrally acquires cloud information containing the target cloud server address, ensuring unified management and timely distribution of switching information, eliminating the need for devices to generate or query addresses themselves. Therefore, by actively acquiring and sending target cloud server address information, IoT devices can automatically complete address switching, avoiding the cumbersome process of manual configuration or local firmware upgrades, improving switching response speed and batch operation efficiency, and thus solving the problems of slow response and low efficiency in traditional methods.

[0046] like Figure 3 As shown in the illustration, this application also provides a cloud address switching method applied to an IoT device. The IoT device can be the IoT device 200 in the above application scenario, or other IoT devices capable of executing the cloud address switching method described in the following embodiments. The cloud address switching method includes the following steps S210 and S220: Step S210: Receive the cloud connection information sent by the cloud server.

[0047] Among them, Lianyun Information includes the target cloud server address that IoT devices need to switch to.

[0048] Specifically, the cloud connection information contains a set of necessary data related to IoT devices connecting to the cloud, primarily used to guide IoT devices in switching their cloud connection addresses. This information includes the target cloud server address that the IoT device needs to switch to, and the communication protocol type of the target cloud server. For example, the target cloud server address could be "http: / / 192.168.1.5 / register" or "http: / / 192.168.1.5 / login". The communication protocol type of the target cloud server could be a protocol type such as MQTT.

[0049] Specifically, the process of receiving cloud information sent by the cloud server can be implemented using various types of communication protocols, such as message push mechanisms based on the MQTT (Message Queuing Telemetry Transport) protocol, or RESTful interface calls via the HTTP (Hypertext Transfer Protocol) protocol, etc.

[0050] In some embodiments, step S210, receiving cloud connection information sent by the cloud server, includes: obtaining the communication status between the IoT device and the cloud server; if the communication status is online, receiving cloud connection information sent by the cloud server; if the communication status is offline, sending a cloud connection request instruction to the cloud server when the communication status changes to online, and receiving cloud connection information sent by the cloud server based on the cloud connection request instruction.

[0051] The communication status between IoT devices and cloud servers refers to the real-time connection status between IoT devices and cloud servers, which can be achieved through heartbeat detection mechanisms, network status query protocols, or device-initiated reporting.

[0052] Among them, the Lianyun request instruction is a request signal initiated by an IoT device to the cloud server when it changes from an offline state to an online state. Its purpose is to notify the cloud server that the device has the ability to receive information and to send a signal to request Lianyun information.

[0053] In this embodiment, the IoT device monitors its communication status with the cloud server in real time. When an online status is detected, the IoT device waits for connection information from the cloud server and receives the connection information when the cloud server sends it, ensuring the immediacy of information transmission. When the IoT device is offline, it automatically triggers a connection request command when it transitions from offline to online. This proactive request mechanism improves the reliability of information acquisition compared to a passive waiting approach. In summary, the IoT device can flexibly adjust its connection information reception strategy based on real-time network conditions, resolving the handover interruption problem caused by device offline status and improving the efficiency and reliability of connection address switching.

[0054] Step S220: Switch to the target cloud server address based on the cloud connection information.

[0055] Specifically, by switching to the target cloud server address based on the cloud connection information, IoT devices can establish a communication connection with the target server using the target cloud server address without intermediate conversion steps or external intervention. This switching mechanism not only simplifies the operation process, but also ensures that multiple devices can synchronously and efficiently complete the switching of cloud addresses in batch scenarios.

[0056] In some embodiments, after performing step S220 and switching to the target cloud server address based on the cloud connection information, the cloud connection address switching method further includes: obtaining the communication status between the IoT device and the target cloud server corresponding to the target cloud server address; if the communication status is online, determining that the switching result is a successful cloud connection address switch; if the communication status is offline, the IoT device switches to the original cloud address and determining that the switching result is a failed cloud connection address switch; and sending the switching result to the cloud server.

[0057] The communication status between the IoT device and the target cloud server corresponding to the target cloud server address refers to the real-time connection status between the IoT device and the target cloud server. This can be achieved through heartbeat detection mechanisms, network status query protocols, or proactive reporting by the device. An "online" communication status means the IoT device and the target cloud server are connected. An "offline" communication status means the IoT device and the target cloud server are not connected.

[0058] The switching result serves as a marker indicating the effectiveness of the IoT device's cloud address switching operation, generating a success or failure status value through logical judgment. The switching result includes successful and failed cloud address switching. In some embodiments, the switching result may also include information such as the IoT device's current cloud address and current cloud type.

[0059] Specifically, after switching to the target cloud server address based on the connection information, the IoT device first obtains the communication status between the IoT device and the target cloud server. If the communication status is online, the IoT device determines that the connection address switch was successful and sends the switch result back to the cloud server to update the device's switch record. If the communication status is offline, the IoT device switches back to the original cloud address, determines that the connection address switch failed, and sends the switch result back to the cloud server. This process provides the cloud server with dynamic management basis through a feedback mechanism. In addition, the above solution solves the service interruption problem caused by the unavailability of the target cloud server or other reasons by introducing status verification and automatic recovery logic, while improving the robustness and efficiency of the connection address switch.

[0060] In summary, this application provides a cloud connection address switching method applied to IoT devices. The IoT device receives cloud connection information sent by a cloud server and switches to the target cloud server address based on this information, enabling the IoT device to automatically complete the address switch. Through unified management and timely distribution of cloud connection information, the IoT device does not need to generate or query addresses itself, nor does it require manual switching. Therefore, by receiving cloud connection information from the cloud server, the IoT device can automatically complete the address switch, avoiding the cumbersome process of on-site manual configuration or local firmware upgrades, improving switching response speed and batch operation efficiency, thus solving the problems of slow response and low efficiency in traditional methods.
