Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to an Internet of Things gateway data synchronization method, system, device and medium. Background Art

[0002] In IoT scenarios, the cloud-based IoT management platform needs to send information such as object models, access scripts, and user configurations to the edge-side IoT gateway. This can lead to two common problems: The IoT gateway may be offline due to network disconnection with the cloud platform, preventing the sent commands from reaching the gateway; and the IoT network environment is often poor, preventing frequent communication of large amounts of data, such as object models, access scripts, and user configurations.

[0003] The existing technology generally adopts the following two solutions: In the first solution, when editing device information of the gateway and its sub-devices, the device must be online to perform addition, deletion, and modification operations, otherwise the operation is not allowed. This solution has a poor user experience. If the gateway is broken and offline, it cannot be directly deleted on the platform, resulting in garbage data.

[0004] The second solution allows for addition, deletion, and modification operations regardless of the online status of the gateway and device. If the device is offline, the platform temporarily stores these operations until the gateway comes online, at which point the platform proactively sends them to the gateway for final completion. This solution temporarily stores operations on the platform and then sends them back online, functionally resolving the poor user experience issue. However, the platform performs the majority of logical decision-making and calculations, leading to a significant impact on the platform when batch operations are performed on offline gateway devices and the gateway comes online at the same time. Summary of the Invention

[0005] The present invention provides an Internet of Things gateway data synchronization method, system, device and medium to solve the problem that when batch operations are performed on offline gateways and devices, logical decision calculations are performed on the platform, resulting in a large impact on the platform when the gateways are online at the same time.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is to provide an IoT gateway data synchronization method, comprising the following steps: a user modifies the configuration of an IoT gateway based on an IoT platform, and the IoT platform updates the content of a gateway topic corresponding to the IoT gateway based on a first protocol; if the IoT gateway is online, the IoT gateway subscribes to the corresponding gateway topic and determines whether the configuration of the IoT gateway needs to be updated based on the content of the gateway topic; if the configuration of the IoT gateway needs to be updated, the IoT gateway sends a configuration update request to the IoT platform; in response to the configuration update request, the IoT platform issues configuration parameters to the corresponding IoT gateway based on the first protocol; the IoT gateway updates the configuration of the IoT gateway based on the received configuration parameters.

[0007] In some embodiments, the step in which the user modifies the configuration of the IoT gateway based on the IoT platform, and the IoT platform updates the content of the gateway topic corresponding to the IoT gateway based on the first protocol, specifically includes: after the user modifies the configuration of the IoT gateway based on the IoT platform, the IoT platform updates the parameter shadow corresponding to the IoT gateway and modifies the version number of the parameter shadow; and the IoT platform publishes the version number of the parameter shadow to the gateway topic corresponding to the IoT gateway based on the first protocol.

[0008] In some embodiments, the step of determining whether the configuration of the IoT gateway needs to be updated based on the content of the gateway topic specifically includes: the IoT gateway compares the version number of the parameter shadow in the gateway topic with the version number stored locally by the IoT gateway; if the version number of the parameter shadow in the gateway topic is consistent with the version number stored locally by the IoT gateway, the configuration of the IoT gateway does not need to be updated; if the version number of the parameter shadow in the gateway topic is inconsistent with the version number stored locally by the IoT gateway, the configuration of the IoT gateway needs to be updated.

[0009] In some embodiments, if the IoT gateway is online, the IoT gateway subscribes to the corresponding gateway topic, and determines whether the configuration of the IoT gateway needs to be updated based on the content of the gateway topic, further comprising the step of: if the IoT gateway is offline, the IoT platform temporarily stores the content of the gateway topic corresponding to the IoT gateway in the first server, and waits for the IoT gateway to come back online.

[0010] In some embodiments, the first protocol is the MQTT protocol, and the first server is an MQTT server.

[0011] The present invention also provides an Internet of Things gateway data synchronization method for an Internet of Things platform, comprising the following steps: based on a user's configuration modification of the Internet of Things gateway, updating the content of the gateway theme corresponding to the Internet of Things gateway through a first protocol; determining whether the Internet of Things gateway is online; if the Internet of Things gateway is online, waiting for the Internet of Things gateway to determine whether its configuration needs to be updated; if the configuration of the Internet of Things gateway needs to be updated, receiving a configuration update request from the Internet of Things gateway, and issuing configuration parameters to the corresponding Internet of Things gateway based on the first protocol; if the Internet of Things gateway is offline, temporarily storing the content of the gateway theme corresponding to the Internet of Things gateway in a first server.

[0012] The present invention also provides an Internet of Things gateway data synchronization method, which is used for an Internet of Things gateway and includes the following steps: based on the online status of the Internet of Things gateway, subscribing to the corresponding gateway topic, and judging whether the configuration of the Internet of Things gateway needs to be updated according to the content of the gateway topic; if the configuration of the Internet of Things gateway needs to be updated, sending a configuration update request to the Internet of Things platform; receiving the configuration parameters issued by the Internet of Things platform, and updating the configuration of the Internet of Things gateway according to the configuration parameters.

DETAILED DESCRIPTION

[0018] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0019] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are intended solely for the purpose of describing specific embodiments and are not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Figure 1 The flowchart of the implementation of the IoT gateway data synchronization method provided by the present application is shown, including the steps: S101: The user modifies the configuration of the IoT gateway based on the IoT platform, and the IoT platform updates the content of the gateway topic corresponding to the IoT gateway based on the first protocol.

[0021] S102: If the IoT gateway is online, the IoT gateway subscribes to the corresponding gateway topic and determines whether the configuration of the IoT gateway needs to be updated based on the content of the gateway topic.

[0022] S103: If the configuration of the IoT gateway needs to be updated, the IoT gateway sends a configuration update request to the IoT platform; in response to the configuration update request, the IoT platform sends configuration parameters to the corresponding IoT gateway based on the first protocol; the IoT gateway updates the configuration of the IoT gateway according to the received configuration parameters.

[0023] This application creates a corresponding gateway theme for each IoT gateway. This allows the IoT platform to save the modified version number to the gateway theme whenever a user modifies the IoT gateway configuration, regardless of whether the IoT gateway is online or the network is good. The platform then retrieves the modified version number once the IoT gateway is online and compares it with the locally stored version number to determine whether an update is needed. This application not only ensures the success rate of IoT gateway configuration modifications in weak network environments but also improves the user experience. It also places the decision-making power on the IoT gateway itself, significantly reducing the computing pressure on the IoT platform.

[0024] The following combination Figures 1 to 6 , this application is further described in detail with specific embodiments.

[0025] like Figure 1 As shown, the IoT gateway data synchronization method provided by the embodiment of the present application is described in detail as follows: S101: The user modifies the configuration of the IoT gateway based on the IoT platform, and the IoT platform updates the content of the gateway topic corresponding to the IoT gateway based on the first protocol.

[0026] Combine Figure 4As shown, it should be noted that User 1 in this application refers to an administrator with login privileges to IoT Platform 2. User 1 can log in to IoT Platform 2 via a webpage or app, and use IoT Platform 2 to modify the configuration of IoT Gateway 3 or add, delete, or modify IoT Devices 4. Modifying the configuration of IoT Gateway 3 refers to modifying the configuration parameters of IoT Gateway 3. Configuration parameters include IP information, connection information, and the ID information of IoT Device 4. IoT Gateway 3 connects to each IoT Device 4 using these configuration parameters. Adding, deleting, or modifying IoT Devices 4 refers to increasing or decreasing the number of IoT Devices 4 connected to IoT Gateway 3, as well as modifying IoT Device 4 information (such as name, configuration, status, etc.). When the number of IoT Devices 4 connected to IoT Gateway 3 changes, its configuration parameters also change accordingly.

[0027] Among them, the IoT platform 2 is a centralized management and control system that can connect multiple device ends and service ends. Its main functions include data collection, statistics, analysis and organization, as well as transmitting the processed data to each terminal device, guiding the device to automatically execute the corresponding instructions and operations. The IoT gateway 3 is a converter that connects the IoT device 4 and the IoT platform 2. It is responsible for converting the data format of the IoT device 4 into a format that the IoT platform 2 can understand, and forwarding commands from the IoT platform 2 to the IoT device 4. It plays the role of an intermediary connecting the IoT device 4 and the IoT platform 2, and is an indispensable part of the IoT system. IoT devices 4 are the basic components of the IoT, including various sensors, smart home appliances, industrial equipment, etc. They are interconnected through IoT technology, can collect and send data to the IoT platform 2, and perform corresponding operations according to the instructions of the IoT platform 2. IoT devices 4 are the concrete embodiment of IoT applications. By connecting to the IoT platform 2, the possibility of intelligence and automation is realized.

[0028] In this embodiment, if Figure 4As shown, user 1 first logs in to IoT platform 2 and uses IoT platform 2 to modify the configuration of the IoT gateway 3 that requires configuration changes. For example, they modify the ID information of one of the IoT devices 4 connected to one of the IoT gateways 3. The modifications are then saved in the database of IoT platform 2. It should be noted that the database of IoT platform 2 stores a parameter shadow corresponding to each IoT gateway 3. Each parameter shadow records the latest configuration parameters of the corresponding IoT gateway 3. When the configuration of an IoT gateway 3 is modified, the corresponding parameter shadow on IoT platform 2 is updated accordingly. After the update is complete, the version number of the parameter shadow is incremented by one. Each time user 1 modifies the configuration of an IoT gateway 3, the version number of the corresponding parameter shadow is incremented by one. For example, before modifying the configuration of IoT gateway 3, the version number of the parameter shadow on IoT platform 2 is V1.0. After modifying the configuration of IoT gateway 3, the corresponding parameter shadow on IoT platform 2 is updated, and the version number of the parameter shadow changes from V1.0 to V1.1.

[0029] Furthermore, in this embodiment, IoT platform 2 creates a corresponding gateway topic for each IoT gateway 3. Each IoT gateway 3 can only access the content of its corresponding gateway topic. Based on the first protocol, IoT platform 2 publishes the modified parameter shadow version number to the gateway topic corresponding to that IoT gateway 3. For example, the modified parameter shadow version number V1.1 is published to its corresponding gateway topic.

[0030] In this embodiment, the first protocol is the MQTT protocol, and the first server is a server corresponding to the first protocol. In this embodiment, the first server is an MQTT server. It should be noted that MQTT (Message Queuing Telemetry Transport) is an instant messaging protocol developed by IBM and is used as a communication protocol for sensors and actuators. It is a publish / subscribe messaging protocol designed for remote devices with low-performance hardware and poor network conditions. The MQTT protocol has a retention mechanism, meaning that information published via the MQTT protocol (such as version numbers) is permanently retained. This allows IoT Gateway 3 to retrieve information by subscribing when it comes back online, even if it is offline.

[0031] S102: If the IoT gateway is online, the IoT gateway subscribes to the corresponding gateway topic and determines whether the configuration of the IoT gateway needs to be updated based on the content of the gateway topic.

[0032] After the IoT platform 2 publishes the version number of the modified parameter shadow to the corresponding gateway topic, it determines whether the corresponding IoT gateway 3 is online.

[0033] If the IoT gateway 3 is online, the IoT gateway 3 subscribes to the corresponding gateway topic and obtains the content in the gateway topic.

[0034] Furthermore, IoT Gateway 3 compares the version number of the parameter shadow in the corresponding gateway topic with the version number stored locally on IoT Gateway 3. If the version number of the parameter shadow in the gateway topic (e.g., V1.1) matches the version number stored locally on IoT Gateway 3 (e.g., V1.1), the configuration of IoT Gateway 3 does not need to be updated. If the version number of the parameter shadow in the gateway topic (e.g., V1.1) does not match the version number stored locally on IoT Gateway 3 (e.g., V1.0), the configuration of IoT Gateway 3 needs to be updated.

[0035] If the IoT gateway 3 is offline, the IoT platform 2 temporarily stores the content of the gateway topic corresponding to the IoT gateway 3 (ie, the version number of the parameter shadow) in the first server, and waits for the IoT gateway 3 to come back online and subscribe to the gateway topic.

[0036] S103: If the configuration of the IoT gateway needs to be updated, the IoT gateway sends a configuration update request to the IoT platform; in response to the configuration update request, the IoT platform sends configuration parameters to the corresponding IoT gateway based on the first protocol; the IoT gateway updates the configuration of the IoT gateway according to the received configuration parameters.

[0037] After comparing the version numbers of the IoT Gateway 3, if they are inconsistent, the configuration of the IoT Gateway 3 needs to be updated.

[0038] Specifically, IoT Gateway 3 sends a configuration update request to IoT Platform 2. Upon receiving the configuration update request, IoT Platform 2 distributes the configuration parameters of IoT Gateway 3 within the parameter shadow corresponding to IoT Platform 2 to the corresponding IoT Gateway 3. Furthermore, IoT Gateway 3 modifies its own configuration based on the latest received configuration parameters and updates the locally stored version number.

[0039] IoT Gateway 3 uses a hot update method to update its configuration. Hot updates are a common update method used by app developers; simply put, they are instant updates that occur when you open an app after downloading and installing it. Hot updates dynamically distribute code, allowing developers to fix bugs and release features without releasing a new version.

[0040] Based on the same inventive concept, Figure 2 As shown, the present invention also provides an Internet of Things gateway data synchronization method for an Internet of Things platform, comprising the steps of: S201: Based on the configuration modification of the IoT gateway by the user, the content of the gateway topic corresponding to the IoT gateway is updated through the first protocol.

[0041] S202: Determine whether the IoT gateway is online.

[0042] S203: If the IoT gateway is online, wait for the IoT gateway to determine whether its configuration needs to be updated; if the configuration of the IoT gateway needs to be updated, receive a configuration update request from the IoT gateway and send configuration parameters to the corresponding IoT gateway based on the first protocol.

[0043] S204: If the IoT gateway is in an offline state, temporarily storing the content of the gateway theme corresponding to the IoT gateway in the first server.

[0046] S302: If the configuration of the IoT gateway needs to be updated, a configuration update request is sent to the IoT platform.

[0047] S303: Receive the configuration parameters issued by the IoT platform and update the configuration of the IoT gateway according to the configuration parameters.

[0048] In this application, other technical features of the above-mentioned IoT gateway data synchronization method for IoT gateway are the same as the features disclosed in the aforementioned method embodiment and will not be repeated here.

[0050] IoT platform 2 is configured to update the content of the gateway topic corresponding to IoT gateway 3 via the first protocol based on configuration modifications made by user 1 to IoT gateway 3; determine whether IoT gateway 3 is online; and, when IoT gateway 3 is online, receive a configuration update request from IoT gateway 3 and issue configuration parameters to the corresponding IoT gateway 3 based on the first protocol.

[0051] IoT Gateway 3 is used to subscribe to the corresponding gateway topic when it is online, and determine whether the configuration of IoT Gateway 3 needs to be updated based on the content of the gateway topic; it is also used to send a configuration update request to IoT Platform 2 when the configuration of IoT Gateway 3 needs to be updated; it is also used to receive configuration parameters issued by IoT Platform 2 and update the configuration of IoT Gateway 3 based on the configuration parameters.

The method includes the following steps: a user modifies the configuration of an IoT gateway based on an IoT platform, and the IoT platform updates the content of the gateway topic corresponding to the IoT gateway based on a first protocol; if the IoT gateway is online, the IoT gateway subscribes to the corresponding gateway topic, and determines whether the configuration of the IoT gateway needs to be updated based on the content of the gateway topic; if the configuration of the IoT gateway needs to be updated, the IoT gateway sends a configuration update request to the IoT platform; in response to the configuration update request, the IoT platform sends configuration parameters to the corresponding IoT gateway based on the first protocol; the IoT gateway updates the configuration of the IoT gateway based on the received configuration parameters. This application creates a corresponding gateway topic for each IoT gateway, so that when a user modifies the configuration of the IoT gateway, regardless of whether the IoT gateway is online or the network environment is good, the IoT platform can save the modified version number to the gateway topic, and obtain it in time after the IoT gateway is online, and compare the locally stored version number to determine whether it needs to be updated. This application not only ensures the success rate of IoT gateway configuration modifications in weak network environments, but also improves the user experience. At the same time, it places the decision-making power of whether the IoT gateway needs to be updated on its own side, greatly reducing the computing pressure of the IoT platform.

[0073] The above are merely embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent structural transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of protection of the present invention.
