Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a communication method, device and message queue telemetry transmission protocol client. Background Art
[0002] Message Queuing Telemetry Transport (MQTT), as a low-overhead, low-bandwidth instant messaging protocol, is widely used in IoT embedded systems. With the continuous development of communication technology, more and more manufacturers support the MQTT protocol in communication modules and provide Attention (AT) instruction sets to control communication modules to connect to cloud platforms and servers through the MQTT protocol. However, due to the large differences in AT instruction sets of different types of communication modules, the application software developed based on a specific AT instruction set has poor portability and high product replacement costs.
[0003] In some existing technical solutions for implementing embedded MQTT clients, the AT instruction set for controlling the Transmission Control Protocol / Internet Protocol (TCP / IP) function in the communication module is usually encapsulated as a socket interface, and then the MQTT protocol and client are implemented on the basis of the socket interface. The disadvantage of these solutions is that users are required to implement the MQTT protocol and client on the basis of the socket, which adds a burden to the writing of user network applications. Moreover, the implementation of the MQTT protocol and client requires more resources, which makes these solutions difficult to apply in resource-constrained embedded systems.
[0004] To sum up, the message queue telemetry transmission protocol client of the prior art needs to communicate data through a specific protocol stack interface, and cannot directly communicate with the communication module with the MQTT protocol through the MQTT client, resulting in poor portability of the communication module with the MQTT protocol in the prior art.

[0043] The present application aims to solve the problem that a message queue telemetry transmission protocol server client in the prior art needs to use a specific protocol stack interface to perform data communication, and provides a communication method, device and message queue telemetry transmission protocol client.
[0044] like Figure 1 As shown, Figure 1 The system diagram of the message queue telemetry transmission protocol (MQTT) client includes: an MQTT client application programming interface 1, and the MQTT application programming interface 2 includes programming interfaces such as MQTT client creation, destruction, connection, subscription, publication, and disconnection, providing basic capabilities for MQTT client application development; multiple communication modules 2, such as the first communication module, the second communication module, and the third communication module, and the three communication modules all include corresponding adaptation functions; a prompt instruction module (AT instruction module) 3, and the AT instruction module executes AT instructions according to the adaptation function of the communication module; further, AT is Attention, and the AT instruction is an instruction for communication sent from a terminal equipment (Terminal Equipment, TE) or a data terminal equipment (Data Terminal Equipment, DTE) to a terminal adapter (Terminal Adapter, TA) or a data circuit terminal equipment (Data Circuit Terminal Equipment, DCE); and a microcontroller not shown in the figure. In this system diagram, the communication module can be understood as an abstract layer module with an MQTT protocol, and each abstract module has a corresponding adaptation function. Here, multiple communication modules are configured in the same MQTT communication module adaptation layer. The following method embodiments are applied to the content of the MQTT client system diagram.
[0045] like Figure 2 As shown, an embodiment of the present application provides a communication method, which is applied to a message queue telemetry transmission protocol MQTT client, wherein the MQTT client includes a prompt instruction module (AT instruction module) and multiple communication modules, including:
[0046] Step 100, obtaining first parameter information, where the first parameter information is used to determine a target communication module that communicates with the prompt instruction module;
[0047] Step 200: Control the prompt instruction module to communicate with the target communication module.
[0048] In this embodiment, step 100 can be performed by Figure 1 The MQTT client application programming interface 1 obtains the first parameter information, and the corresponding target communication module can be identified according to the first parameter information, and the target communication module is controlled through the AT command module to realize the MQTT client communication function.
[0049] It should be noted that the multiple communication modules included in the MQTT client are all abstract layer modules. The abstract layer module identifies the corresponding target adaptation function according to the first parameter, and calls the corresponding target adaptation function to achieve information interaction with the AT command module.
[0050] It should be known that any communication module or target communication module not specifically explained in the present application is understood to be an abstract layer module with an adaptation function.
[0051] Specifically, the multiple communication modules are configured in the same adaptation layer.
[0052] Furthermore, the adaptation layer is a collection of communication terminals that have been adapted to the application programming interfaces of multiple communication modules, providing the ability to control the communication terminals through corresponding AT instruction sets.
[0053] In this embodiment, the multiple communication modules are configured in the same adaptation layer, that is, communication modules with multiple different function combinations are configured in the same adaptation layer, and the adaptation function of each communication module refers to the function that matches the function, parameters, and return value requirements of the MQTT application programming interface by executing specific AT instructions.
[0054] Specifically, the communication module can use a first type of communication protocol and / or a second type of communication protocol;
[0055] The first type of communication protocol includes: message queue telemetry transmission protocol MQTT;
[0056] The second type of communication protocol includes at least one of the following: third-generation mobile communication technology 3G, third-generation mobile communication technology 4G, third-generation mobile communication technology 5G, narrowband Internet of Things NB-IoT and wireless communication technology Wi-Fi.
[0057] Here, the communication module uses the first type of communication protocol, and communicates with the actual communication terminal through at least one second type of communication protocol through the AT command module, eliminating the process of building a TCP / IP network protocol stack and realizing the function of communicating with a communication terminal having the first type of communication protocol and / or the second type of communication protocol.
[0058] Optionally, the step 200 includes:
[0059] Step 210, determining a target adaptation function corresponding to the target communication module according to the target communication module;
[0060] It should be known that the target adaptation function refers to a set of AT commands for communicating with the communication module through a hardware interface such as a serial port.
[0061] Step 220: Control the prompt instruction module to communicate with the target communication module according to the target adaptation function.
[0062] In this embodiment, the target adaptation function determined by the target communication module can notify the prompt instruction module to communicate with the target communication module according to the instruction of the target adaptation function. Here, the target adaptation function at least includes an execution instruction function, a reception instruction function and a parsing instruction function. According to each different instruction function, the communication content between the prompt instruction module and the target communication module is different.
[0063] Specifically, when the target adaptation function is an execution instruction function, step 220 includes:
[0064] Control the prompt instruction module and the target communication module to execute the operation corresponding to the execution instruction function through the preset interface transmission;
[0065] The preset interface includes a universal asynchronous receiver / transmitter (UART) interface, a serial peripheral interface (SPI) interface, or a universal serial bus (USB) interface.
[0066] In this embodiment, the preset interface is provided in the hardware driver layer of the MQTT client, and the preset interface includes one or more of USB, SPI, and UART.
[0067] Here, USB, the full name of which is Universal Serial Bus, is an external bus standard used to regulate the connection and communication between computers and external devices. SDIO, the full name of which is Secure Digital Input and Output, defines a peripheral interface, which mainly includes two types of applications: removable and non-removable. SPI, the full name of which is Serial Peripheral Interface, is a high-speed, full-duplex, synchronous communication bus. I2C, the full name of which is Inter-Integrated Circuit, is a communication bus that only needs two wires to transmit information between devices connected to the bus. UART, the full name of which is Universal Asynchronous Receiver / Transmitter, is a universal serial data bus used for asynchronous communication. The bus has bidirectional communication and can achieve full-duplex transmission and reception.
[0068] Through the above-mentioned preset interface, data can be transmitted between the prompt instruction module and the target communication module, thereby realizing control of the communication connection between the prompt instruction module and the target communication module.
[0069] Specifically, when the target adaptation function is a receiving instruction function, step 220 includes:
[0070] According to the receiving instruction function, controlling the prompt instruction module to receive the response data and / or the actively reported data sent by the target communication module;
[0071] Among them, the response data is the response data after the target communication module executes at least one of the target adaptation functions; the actively reported data is the response data after the target communication module fails to execute the target adaptation function.
[0072] In this embodiment, analysis or data cleaning can be performed based on the response data and / or actively reported data sent by the target communication module; here, the data cleaning includes: data filtering, the original data includes the response data and / or actively reported data sent by the target communication module, and the response data sent by the target communication module is filtered out; data classification, the actively reported data includes heartbeat data, status data of the target communication module, alarm data and other sampling data, which can determine whether this communication is abnormal.
[0073] Specifically, when the target adaptation function is a parsing instruction function, the step 220 further includes:
[0074] According to the parsing instruction function, the prompt instruction module is controlled to parse the received response data and / or the actively reported data.
[0075] In this embodiment, the data is mainly parsed to determine the result of this communication. Further, the parsing instruction function will call the prompt instruction module to receive the response data and / or the active reporting data, and use the parsing result of the AT instruction parsing module as the basis for the return value of the parsing instruction function.
[0076] Optionally, the method further includes:
[0077] Step 300, sending a first message to the MQTT server through the target communication module, wherein the first message includes a topic subscription message and / or a topic publishing message;
[0078] Step 400: receiving a prompt instruction fed back by the MQTT server through the target communication module.
[0079] In this embodiment, before sending the first message to the MQTT server, the target communication module needs to establish a communication connection with the MQTT server. The following explains steps 300 to 400 with a specific embodiment.
[0080] Specifically, initialize the MQTT client, call the MQTT client initialization interface, and set various parameters of the MQTT client. The MQTT client identifies the need to call the first target module initialization adaptation function through the first parameter; the second step: connect to the MQTT broker (Broker), call the MQTT client connection interface; the third step: subscribe to the MQTT topic, call the MQTT client subscription interface through step 300, or publish the MQTT topic message, call the MQTT client publishing interface, and implement the topic subscription message and / or topic publishing message through the first message; through step 400, receive the prompt instruction fed back by the MQTT server, and perform corresponding operations according to the prompt instruction fed back. That is, receive the subscribed topic MQTT message, the target communication module actively reports the MQTT message of the topic subscribed by the client according to the feedback prompt instruction, the MQTT client receives the MQTT message, and executes the corresponding callback function to notify the user that the subscribed message has arrived and performs the corresponding processing. Of course, if you want to disconnect, you can also send a second message to the MQTT server through the target communication module, and the second message includes disconnecting the connection with the MQTT agent.
[0081] In summary, the method of the present application realizes MQTT client communication interaction by directly calling the AT instruction set that controls MQTT-related functions in the communication module, avoiding the burden of additional transplantation or implementation of the MQTT protocol; the communication module adaptation layer of the present application realizes compatibility with multiple AT instruction sets, shields the differences in AT instruction sets between different communication modules, and improves the development of application programs. The present application avoids the implementation of the intermediate socket adaptation layer and the MQTT protocol, is lightweight and concise, and is more suitable for resource-constrained IoT embedded systems.
[0082] In a specific embodiment, if Figure 3 As shown, Figure 3 A schematic diagram of a connection between an embedded system and a cloud platform is shown, wherein the embedded system includes: an MQTT client 4, an actual communication module 5 and other peripherals and sensors 6; the structure of the MQTT client 4 is Figure 1 On the basis of the client shown, an application (which can be understood as a cloud platform application) and an operating system are connected; the actual communication module 5 communicates with the communication module of the MQTT client 4. In the embedded system, the information of the application is obtained by calling the MQTT client application programming interface of the MQTT client 4, and the data of the other peripherals and sensors 6 are obtained through other related interfaces, and then the obtained data is published to the cloud platform 7 through the MQTT client 4 and subscribed to related topics (Topic) to obtain data published by other terminal devices.
[0083] Specifically, through Figure 4 The workflow diagram of the MQTT client embodiment is described. Here, the workflow of the MQTT client embodiment is described by taking the ML302 module as an example. However, the present invention is compatible with communication modules of different AT instruction sets and is not limited thereto:
[0084] Step 1: Initialize the MQTT client, call the MQTT client initialization interface, and set various parameters of the MQTT client. The MQTT client recognizes that it needs to call the ML302 module initialization adaptation function through the first parameter information, and the adaptation function executes the first AT command. The first AT command is:
[0085] "AT+MQTTCFG=" <host> , <port> , <id> , <keepalive> , <user> , <passwd>,<
[0086] clean>, <version> , <encrypt>”.
[0087] Step 2: MQTT client connection, calling the MQTT client connection interface. In this embodiment, the MQTT connection is a preset cloud platform. The corresponding adaptation function is identified through the first parameter information and the second AT command is executed. The second AT command is:
[0088] "AT+MQTTOPEN= <usrflag> , <pwdflag> , <willflag> , <willretain>,<will
[0089] Qos>, <will-topic> , <will-mesg>”.
[0090] Step 3: MQTT client subscription (topic subscription), call the MQTT client subscription interface, identify the corresponding adaptation function through the first parameter information and execute the third AT command "AT+MQTTSUB= <topic> , <qos>”.
[0091] Step 4: The MQTT client subscribes (topic publishing), calls the MQTT client publishing interface, identifies the corresponding adaptation function through the first parameter information, and executes the fourth AT instruction.
[0092] The fourth AT command is: "AT+MQTTPUB= <topic> , <qos> , <retain> , <dup> , <message>”;
[0093] Step 5: The MQTT client receives the subscribed topic MQTT message, and the communication module actively reports the MQTT message of the topic subscribed by the client according to the fifth AT command.
[0094] The fifth AT command is:
[0095] "+MQTTPUBLISH: <dup> , <qos> , <retained> , <packid> , <topic>,<msg_le
[0096] n>, <mesg>”;
[0097] The MQTT client receives the MQTT message and executes the corresponding callback function to notify the user that a subscribed message has arrived and performs corresponding processing.
[0098] Step 6: The MQTT client disconnects; that is, disconnects from the cloud platform, calls the MQTT client disconnection interface, identifies the corresponding adaptation function through the first parameter information, and executes the AT command "AT+MQTTDISC".
[0099] Here, the embodiment of the present application only takes one communication module as an example. The present application supports communication among multiple communication modules that can use the first type of communication protocol and / or the second type of communication protocol, and realizes direct communication between the communication module and the MQTT client.
