[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] The following describes the method, device and Internet of Things gateway for publishing business messages in an embodiment of the present application in conjunction with the accompanying drawings.

[0034] Figure 1 is a flow chart of a method for publishing a service message according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0035] S101, subscribing to a message topic sent by a first terminal device to obtain a business message sent by the first terminal device based on a message queue telemetry transmission MQTT protocol.

[0036] The execution entity in the embodiment of the present application may be an Internet of Things gateway.

[0037] Message Queuing Telemetry Transport (MQTT) is a lightweight publish / subscribe messaging protocol suitable for IoT and remote device communications.

[0038] Optionally, in an embodiment of the present application, the first terminal device is an Internet of Things device. The first terminal device publishes a business message to the Internet of Things gateway through the MQTT protocol, including information such as the message subject and the message content. The Internet of Things subscribes to the message subject sent by the first terminal device, and obtains the business message sent by the first terminal device based on the message queue telemetry transmission MQTT protocol according to the message subject.

[0039] That is to say, in the embodiment of the present application, the IoT gateway and the terminal device communicate in the form of message (Topic) subscription and publication.

[0040] In some embodiments, the business messages of each message topic sent by the first terminal device based on the MQTT protocol are directly received; in some embodiments, the short message sent by the first terminal device based on the MQTT protocol is received in the form of a message queue, the short message is identified, and the business message under each message topic is determined.

[0041] S102, for each business message under the message subject, decode the business message and convert it into a first format to obtain a standard message in a preset standard data format.

[0042] In the embodiment of the present application, the standard data format is a predefined standard device message format.

[0043] The IoT gateway decodes and converts the business message into the first format, parses the business message into a standard data format that can be recognized by the backend service, and obtains a standard message (DeviceMessage) in a preset standard data format, which is used to represent various data, status information or control commands generated by the device. The standard message format may include parts such as the message header, message body and message tail, and specifies the meaning and value range of each field in the message.

[0044] The IoT device decodes and converts the business message into the first format, and obtains the standard message according to the agreed standard message format.

[0045] S103: triggering an action based on the standard message, and publishing the standard message to the second terminal device in the form of message subscription.

[0046] Among them, the second terminal device is an Internet of Things device or a satellite device.

[0047] The DeviceMessage action trigger set is determined based on the standard message, the data stream is processed based on the DeviceMessage action trigger set, and the standard message is published to the second terminal device in the form of message subscription, which can make it easier for the terminal device and the IoT gateway to exchange data and interoperate with each other. In other words, the message is forwarded to all one or more second terminal devices that subscribe to the message topic, and the second terminal device then chooses whether to receive the message based on its own subscription status.

[0048] In some implementations, before publishing the standard message to the second terminal device in the form of a message subscription, the standard message is converted into a second format, wherein the second format conversion is an inverse conversion of the first format conversion.

[0049] In an embodiment of the present application, the business message is decoded and converted into a first format to obtain a standard message in a preset standard data format. The gateway supports a variety of different data formats, can help connect different devices and systems, improve the interoperability and flexibility of the device, trigger actions based on standard messages, publish standard messages to IoT devices or satellite devices in the form of message subscriptions, and enable the device to send and receive satellite short message messages. It uses an extensible, high-performance event-driven, non-blocking asynchronous programming framework (Vert.x framework), which can handle a large number of concurrent connections, is suitable for large-scale device access, and can be easily expanded horizontally.

[0050] Figure 2 is a flow chart of a method for publishing a service message according to an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0051] S201, performing connection authentication on the first terminal device.

[0052] There are many ways to authenticate the connection between the first terminal device and the IoT gateway, and the specific method selected depends on the system requirements and security considerations.

[0053] For example, in some implementations, when the first terminal device is connected to the IoT gateway, it provides a pre-assigned device identification and password for verification, and the IoT gateway performs identity authentication based on the provided credentials and performs connection authentication for the first terminal device.

[0054] In some implementations, both the first terminal device and the IoT gateway hold corresponding digital certificates. During the connection process, both parties can verify the validity of each other's certificates to achieve connection authentication.

[0055] In some implementations, the first terminal device carries specific token information when connecting, and the IoT gateway performs verification based on the token to authenticate the connection of the first terminal device.

[0056] In some implementations, the Secure Sockets Layer / Transport Layer Security (TLS / SSL) protocol is used to encrypt the connection between the device and the network management, to authenticate the connection of the first terminal device, and to ensure the privacy and integrity of the connection.

[0057] Optionally, the above methods can be used alone or in combination to achieve more stringent connection authentication. In the embodiment of the present application, there is no restriction on the method of connection authentication.

[0058] S202: If the authentication is successful, a communication transmission connection is established between the first terminal device and the Internet of Things gateway.

[0059] When the authentication is successful, a communication transmission connection is established between the first terminal device and the Internet of Things gateway, thereby ensuring the security of the connection.

[0060] S203, subscribing to the message topic sent by the first terminal device to obtain the business message sent by the first terminal device based on the message queue telemetry transmission MQTT protocol.

[0061] For the introduction of step S203, please refer to the relevant content in the above embodiment, which will not be repeated here.

[0062] It should be noted that the service message carries the first identifier of the first terminal device.

[0063] S204, decoding the business message under each message topic to obtain the decoded business message.

[0064] In the embodiment of the present application, the message is decoded into a readable data format, and a corresponding target decoder is selected according to the message type of the business message.

[0065] For example, there is a mapping relationship between the message type and the candidate decoders, and the target decoder corresponding to the message type of the service message is obtained based on the mapping relationship to facilitate subsequent decoding of the service message context.

[0066] S205, obtaining one or more target fields in a preset standard data format, identifying the decoded business message according to each target field, and extracting the target message corresponding to each target field.

[0067] In some embodiments, if the first terminal device is an IoT device, the target field may include one or more of the following: the first terminal device's identification, reception type, message identification, message content, service type, the second terminal device's identification and timestamp, device identification, platform type, information type, data type, tenant identification, etc.

[0068] In some embodiments, if the first terminal device is a satellite device, the target field may include one or more of the following: message header identifier, tenant identifier, message type, device identifier, message address, second terminal device identifier, message content, device name, timestamp, etc.

[0069] S206, encapsulate the target message to obtain a standard message.

[0070] For example, a data template in a preset standard data format can be obtained, where the template includes one or more target fields. The decoded business message is identified according to each target field, and the target message corresponding to each target field is extracted. The data template is filled according to the target message, and then encapsulated to obtain a standard message.

[0071] By encapsulating and combining target messages to obtain standard messages, the integrity, security and consistency of data can be ensured.

[0072] S207: query whether the first terminal device has satellite forwarding authority based on the first identifier, and determine the identifier of the second terminal device that subscribes to the message topic.

[0073] The device operation authority is obtained based on the first identifier, and forwarding authority authentication is performed to determine whether the first terminal device has satellite forwarding authority.

[0074] S208, if the first terminal device does not have satellite forwarding authority, and the second terminal device is an IoT device, routing is performed based on the message subject and the second terminal device identifier, and the standard message is forwarded to the second terminal device through the action trigger of the standard message.

[0075] S209, if the first terminal device has satellite forwarding authority and the second terminal device is a satellite device, the standard message is forwarded to the satellite short message server through the action trigger of the standard message, and the satellite short message server routes based on the message subject and the second terminal device identifier, and forwards the standard message to the second terminal device.

[0076] In some implementations, before publishing the standard message to the second terminal device in the form of a message subscription, the standard message is converted into a second format, wherein the second format conversion is an inverse conversion of the first format conversion.

[0077] S210, storing the published standard message in a database and recording a message publishing log to support data analysis and use.

[0078] In an embodiment of the present application, a message publishing log is recorded, and data sent by the gateway, such as standard messages, is stored in a database. Optionally, it can also be stored in an open source distributed search and analysis engine (ElasticSearch, ES) to support subsequent data analysis and use.

[0079] In the embodiment of the present application, the first terminal device is connected and authenticated. If the authentication is successful, a communication transmission connection is established between the first terminal device and the IoT gateway, which can realize encrypted data transmission and authentication to ensure the security and integrity of the data. The gateway can quickly access various MQTT devices and seamlessly connect them to the backend service. It adopts a publish / subscribe mode, which can realize two-way communication between different IoT devices and applications. By dividing permissions, it supports multi-device management, realizes resource isolation and security between different devices, avoids compatibility and interoperability issues, and improves the scalability and compatibility of the gateway.

[0080] Figure 3 FIG. 1 is a schematic diagram of triggering an action through a standard message according to an embodiment of the present application. Figure 3 As shown, in some embodiments, data forwarding and processing are performed based on DeviceMessage (standard message), and the business message includes information such as device, function call, and time report. The business message is decoded and converted to the first format, and the standard message in the standard data format is obtained. The DeviceMessage action trigger set is obtained, and different event processing nodes Node are triggered according to different device attributes and device functions of the standard information, and different device actions DeviceAction are executed. For example, the action triggers a logger (Logger) for recording and tracking specific actions or events, such as an action triggering application programming interface action API Action, and the standard message is forwarded to the satellite short message server by calling the API interface, such as the action triggering message downlink attribute, and the message is passed to the next operation in the data pipeline. For example, when the standard message execution node of the device output is reached, the standard message is published to the second terminal device through the gateway connection.

[0081] Based on the same concept, the embodiment of the present application also provides an IoT gateway with integrated satellite short messages. It provides a set of rules based on the rule engine, which can route messages to different targets, such as forwarding sensor data to specific applications, devices or databases. In addition, it also integrates the satellite short message function, and authorized devices can send data in a specified format through this gateway to implement the satellite short message communication function, and provides a web console so that users can easily manage and monitor devices and message flows.

[0082] Figure 4 is a structural diagram of an Internet of Things gateway according to an embodiment of the present disclosure, such as Figure 4 As shown, the Internet of Things gateway includes a connected access module and a data transceiver module. Optionally, the Internet of Things gateway is an Internet of Things MQTT device gateway integrating satellite short messages.

[0083] The access module is used to establish a communication transmission connection between the Internet of Things gateway and the first terminal device, and obtain the business message sent by the first terminal device based on the message queue telemetry transmission MQTT protocol.

[0084] The data transceiver module is used to process and parse the received business messages and forward the business messages to the second terminal device, which is a satellite device or an Internet of Things device.

[0085] In some embodiments, the access module includes a device access module and a communication management module, wherein:

[0086] The device access module has a fixed port for connecting to the first terminal device. That is, the first terminal device is connected to the satellite MQTT gateway through the fixed port exposed by the access module, and communicates with the gateway in the form of message (Topic) subscription and publication.

[0087] The communication management module is used to authenticate the connection of the first terminal device, establish communication transmission with the first terminal device after successful authentication, and obtain business messages. In other words, the communication management module manages and maintains the connection between the IoT gateway and other devices, and handles related transactions in the connection, such as connection authentication. After the IoT gateway subscribes to and receives the business message sent by the first terminal device, it will be handed over to the data forwarding module for processing.

[0088] The data processing module is responsible for processing and parsing the received data, including operations such as data conversion, data storage, and data filtering, and also supports customized data processing logic. In some embodiments, the data transceiver module includes a data processing module, a satellite short message forwarding module, and a data push module, wherein:

[0089] The data processing module is used to decode and convert the service message into a first format, obtain a standard message in a preset standard data format, and send the standard message to the satellite short message forwarding module or the data push module.

[0090] The satellite short message forwarding module is used to send the standard message to the satellite short message server, and the satellite short message server forwards the standard message to the satellite device.

[0091] The data push module is used to send standard messages to IoT devices.

[0092] In some implementations, the IoT gateway further includes a data storage module for storing standard messages and recording message publishing logs.

[0093] That is to say, the gateway supports forwarding data to the satellite short message platform and IoT devices through authorized configuration and calling of external satellite platforms, while recording information push logs and storing the data sent by the devices in ES for subsequent data analysis and use. When forwarding messages, routing is performed based on Topic and device identification, supporting message filtering and conversion functions, and conditional judgment and conversion can be performed based on the content of the message to ensure the correctness and reliability of the message.

[0094] The embodiments of the present application provide extended interfaces for data pre-processing and post-processing, which can easily implement customized data processing logic, such as data decryption, data format conversion, etc., and support customized data processing.

[0095] Optionally, the satellite device in the embodiment of the present application may be a Beidou satellite device, and the corresponding satellite short message is a Beidou satellite short message. In other implementations, the satellite may also be other satellites, such as a high-orbit satellite or a low-orbit satellite, etc. The embodiment of the present application is not limited to this.
