[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0019] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0020] See also Figure 1 , Figure 1 : is a flow chart of an IoT terminal operation and maintenance method based on the MQTT protocol provided in an embodiment of the present application. In an embodiment of the present application, the method includes: S101, establishing a communication connection between the platform and the IoT terminal based on the MQTT protocol, setting a silent period, and executing S102 once in each silent period; S102, the IoT terminal sends update information to the platform, and the platform generates an operation and maintenance message after receiving the update information. The platform sends the operation and maintenance message to the IoT terminal, and the IoT terminal receives the operation and maintenance message sent by the platform and executes the operation command. The platform receives the execution result fed back by the IoT terminal.

[0021] It should be noted that the platform side can specifically be a cloud service platform, which can be integrated on a server, and the platform side stores information of the IoT terminals in the entire system.

[0022] In the embodiment of this specification, the IoT terminal first sends a CONNECT data packet to the platform end, and this data packet includes various parameters of the connection request, such as the protocol version, the client identifier, etc. After receiving the CONNECT data packet, the platform end will perform identity authentication and authority verification. If the verification is successful, the platform end will send a CONNACK data packet to the IoT terminal, indicating that the communication connection has been established, and the IoT terminal and the platform end can start communicating. Then set a silent period, and perform the following operation and maintenance operations once in each silent period: the IoT terminal first sends update information to the platform end. After the platform end receives the update information, the operator can call up the update information initiated by the IoT terminal from the PC end, so as to interact with the platform end to issue operation and maintenance tasks. After receiving the operation and maintenance tasks, the platform end will generate an operation and maintenance message and send the operation and maintenance message to the IoT terminal. The IoT terminal has the operation and maintenance process required by the IoT terminal pre-integrated inside. After receiving the operation and maintenance message, the IoT terminal will execute the pre-set process according to the content of the operation and maintenance message. After the operation and maintenance operation of the IoT terminal is completed, the IoT terminal will feedback the execution result to the platform end.

[0023] To summarize, in the present application, a communication connection is established between the platform and the IoT terminal through the MQTT protocol. The IoT terminal can actively communicate with the platform without the need for the platform to actively send a request to obtain data. The time required for the operation and maintenance of each IoT terminal is shortened, thereby improving the operation and maintenance efficiency. By setting a silent period, the IoT terminal only performs communication and operation and maintenance operations once within a period of time, thereby avoiding the traffic consumption caused by constant communication, thereby saving the required traffic during the operation and maintenance of the IoT terminal.

[0024] Specifically, the silent period is 24 hours, that is, the IoT terminal will report update information and perform an operation and maintenance operation every 24 hours.

[0025] In one possible implementation, the update information includes configuration information of the IoT terminal, device attributes of the IoT terminal, and device status of the IoT terminal. The operator calls up the configuration information of the IoT terminal, the device attributes of the IoT terminal, and the device status of the IoT terminal to determine what operation and maintenance operation should be performed on each IoT terminal.

[0026] In one possible implementation, before the IoT terminal sends an update message to the platform, the IoT terminal will send a subscription message to the platform. The subscription message is presented in the form of a message, requesting to subscribe to a certain topic. After receiving the subscription message, the platform will confirm the subscription and return the subscription result, which is also presented in the form of a message. The operation and maintenance message includes the message subject corresponding to the subscription message and the message of the message subject. The message subject is used to identify the message, thereby classifying the message, making the communication between the platform and the IoT terminal more efficient.

[0027] It should be noted that the message subject is specifically a character string that identifies the communication information between the IoT terminal and the platform. When the IoT terminal communicates with the platform, all messages sent by both the IoT terminal and the platform carry a message subject. The IoT terminal can subscribe to a single or multiple topics. When the platform sends a message with a certain topic, all IoT terminals that subscribe to the topic can receive it.

[0028] Furthermore, the message subject includes a first subject segment and a second subject segment, the first subject segment indicates the device number of the IoT terminal, and the second subject segment indicates the actual message subject. The first subject segment indicates the device number of the IoT terminal. When the platform sends an operation and maintenance message to the IoT terminal, the corresponding IoT terminal will be retrieved according to the device number to ensure orderly and correct communication.

[0029] Specifically, the actual message topics include an upgrade task topic, a debugging task topic, an application installation task topic, and a log acquisition task topic.

[0030] For example, if an IoT terminal subscribes to the update topic, then after the platform sends a message with the update topic, all IoT terminals that subscribe to the update topic will receive the message. The IoT terminal will determine it as an upgrade task and then execute the upgrade process integrated in the IoT terminal.

[0031] In one possible implementation, when setting the silent period, the waiting time is also set. When the IoT terminal sends the update information to the platform, the timing starts. If the information sent by the platform is not received after the waiting time, the next silent period begins. By setting the waiting time, the IoT terminal can avoid the situation where it has to wait for information from the platform, thereby avoiding the waste of communication resources.

[0032] Specifically, the waiting time is generally set to 1 minute.

[0033] In one possible implementation, the IoT terminal also executes an operation and maintenance message execution process, a task retry process, and a task rollback process. That is, the operation and maintenance module needs to include an operation and maintenance message execution process, which is used to execute the operation and maintenance message according to the process. In addition, it can also include one or more of the task retry process and the task rollback process, so as to realize task retry, task rollback, etc. The operation and maintenance message retry process is to retry the operation and maintenance message, and the operation and maintenance message rollback process is to roll back the executed operation and maintenance message.

[0034] The following will be combined with the attached Figure 2 , the IoT terminal operation and maintenance device provided in the embodiment of the present application is introduced in detail. It should be noted that the attached Figure 2 The IoT terminal operation and maintenance device shown is used to execute this application Figure 1 For the convenience of explanation, only the part related to the embodiment of the present application is shown.

Figure 2 As shown, the device comprises: The first operation and maintenance module is used to establish a communication connection between the platform and the IoT terminal based on the MQTT protocol, set a silent period, and execute the content of the second operation and maintenance module once in each silent period; The second operation and maintenance module is used for the IoT terminal to send update information to the platform. After receiving the update information, the platform generates an operation and maintenance message. The platform sends the operation and maintenance message to the IoT terminal. The IoT terminal receives the operation and maintenance message sent by the platform and executes the operation command. The platform receives the execution result fed back by the IoT terminal.

[0036] Furthermore, the update information includes configuration information, device attributes and device status of the IoT terminal.

[0037] Furthermore, the following steps are performed before the IoT terminal sends update information to the platform: The platform receives a subscription message sent by the IoT terminal, where the subscription message is used to subscribe to all messages containing a certain message topic; The operation and maintenance message includes a message subject corresponding to the subscription message and a message of the message subject.

[0038] Furthermore, the message topic includes a first topic segment and a second topic segment, the first topic segment represents the device number of the Internet of Things terminal, and the second topic segment represents the actual message topic.

[0039] Furthermore, the actual message topics include an upgrade task topic, a debugging task topic, an application installation task topic, and a log acquisition task topic.

[0040] Furthermore, the method further comprises: A waiting time is set. If the IoT terminal does not receive the operation and maintenance information during the waiting time, it enters the next silent cycle after the waiting time.

[0041] Furthermore, the silent period is 24 hours.
