Detailed Description
In order to make the technical solutions in the present specification better understood, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the accompanying drawings in one or more embodiments of the present specification, and it is obvious that the one or more embodiments described are only a part of the embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.
The target intelligent device related to the embodiment of the present specification refers to any device, instrument or machine with computing and processing capabilities, and has a sensitive and accurate sensing function, a correct thinking and judging function and an effective execution function. The intelligent refrigerator can be an intelligent refrigerator, an intelligent air conditioner and the like.
The cloud end, namely the cloud server, provides an interface for the intelligent terminal to query data and process data and the like.
Target APP, software installed on a user terminal, has functions of user login, device binding (target intelligent device), and MQTT integration.
MySQL database, a relational database management system, stores data in different tables instead of putting all data in one large repository, which increases speed and flexibility.
The Redis database, namely REmote DIctionary Server (Redis), is a key-value storage system which runs based on memory and has high performance efficiency.
MQTT (Message Queuing Telemetry Transport) is a "lightweight" communication protocol based on publish/subscribe (publish/subscribe) mode. The intelligent device receives and pushes the message published by the management platform in real time through the MQTT in a mode of subscribing by taking user information as a theme.
In order to solve the technical problem in the background art, an embodiment of the present specification provides a scheme for synchronizing attribute information of an intelligent terminal based on a message queue telemetry transmission MQTT technology. When the user passes through APP controlgear, when local APP refreshes equipment information, other controllers/binding persons of the equipment are informed through the mode of MQTT push/notification, equipment information is refreshed immediately on other APPs through the mode, instant synchronization of information is achieved, and user experience is improved.
Referring to fig. 1b, a schematic view of a scene architecture applicable to a scheme for synchronizing attribute information of an intelligent terminal based on MQTT according to an embodiment of the present specification is shown. In the scenario architecture, the method can include: the system comprises a plurality of user terminals 102 provided with target APP, a cloud server 104, a database 106, an MQTT service platform 108 and a target intelligent terminal 110. Wherein, one user terminal 102 of the plurality of user terminals 102 controls the target intelligent terminal 110 by using the target APP under the operation of the user, and updates the attribute information of the target intelligent terminal 110 on the local target APP. Meanwhile, the updated attribute information is uploaded to the cloud server 104, so that the cloud server 104 determines other user terminals 102 associated with the target smart terminal 110 according to the target smart terminal 110. Then, the cloud server 104 packages the received attribute information into MQTT messages and issues the MQTT messages to the other user terminals 102, so that the other user terminals 102 update and synchronize the attribute information of the target intelligent terminal 110 on the local target APP.
In this way, unique identifiers of a plurality of user terminals bound with (i.e. installed with) the target intelligent terminal 110 are stored on the cloud server 104, so that the binding relationship is not required to be stored among the user terminals and updated attribute information is directly transmitted, only the cloud server 104 is required to assist transmission, and the cloud server 104 immediately issues the acquired updated attribute information of the target intelligent terminal to other user terminals in an MQTT message manner, so that other user terminals can immediately and accurately synchronize the latest updated attribute information of the target intelligent terminal on the local target APP, uniform and accurate attribute information on the target APPs of all user terminals associated with the target intelligent terminal is ensured, and user control experience is improved.
The following is a detailed description of the examples of the present specification.
Referring to fig. 2, a schematic diagram of steps of a method for synchronizing attribute information of an intelligent terminal based on MQTT provided in an embodiment of the present description is shown, where the method includes:
step 202: after a first user terminal logs in a target APP, initializing Message Queue Telemetry Transmission (MQTT) services deployed among all user terminals provided with the target APP, wherein the target APP is an application program used for controlling a target intelligent terminal.
Optionally, in step 202, when initializing a message queue telemetry transmission MQTT service deployed among all user terminals installed with the target APP, the first user terminal specifically subscribes to the MQTT service based on user information of the first user terminal, where the MQTT service is deployed among all user terminals installed with the target APP, and the user information at least includes: and (4) identifying the user. Therefore, the first user terminal initiating the control request can initiate the subscription of the MQTT service in the local target APP, and after the subscription is successful, the MQTT messages can be instantly transmitted between the plurality of user terminals deploying the MQTT service and the cloud.
Step 204: and after the first user terminal controls and processes the target intelligent terminal based on the target APP, updating the attribute information of the target intelligent terminal related to the control processing operation in the local target APP.
The first user terminal performs control processing on the target intelligent terminal based on the target APP, and the control processing may include: controlling the target intelligent terminal to adjust the equipment state and controlling the target intelligent terminal to alarm equipment; for example, when the target intelligent terminal is an intelligent refrigerator, the intelligent refrigerator can be controlled to automatically adjust the temperature of the refrigerator body, or the intelligent refrigerator can be controlled to automatically shut down or start up. Correspondingly, the attribute information of the target intelligent terminal at least comprises: alarm information, equipment state update information and fault information.
Step 206: and the first user terminal calls a cloud interface and reports the recently updated attribute information of the target intelligent terminal to a cloud.
Step 208: and the cloud determines other second user terminals bound with the target intelligent terminal, and sends the attribute information to the other second user terminals in the form of MQTT messages.
Optionally, when the cloud determines another second user terminal bound to the target intelligent terminal, specifically, based on the unique identifier of the target intelligent terminal corresponding to the received attribute information, it may be determined whether another user identifier associated with the unique identifier exists in a Redis database; if the user terminal corresponding to the other user identification is found in the Redis database, determining the user terminal corresponding to the other user identification as other second user terminals; if the unique identifier is not found in the Redis database, further searching whether other user identifiers related to the unique identifier exist in the Mysql database; and if the user terminal corresponding to the other searched user identifier is found in the Mysql database, determining the user terminal corresponding to the other searched user identifier as the other second user terminal, and if the user terminal is not found in the Mysql database, not processing the user terminal.
Further, when the cloud sends the attribute information to the other second user terminals in the MQTT message, service data may be specifically encapsulated based on an operation instruction corresponding to service processing content included in the attribute information; and issuing the MQTT message obtained after encapsulation to the other second user terminals.
Step 210: and after receiving the MQTT message, the other second user terminals respectively update and synchronize the attribute information of the target intelligent terminal in the local target APP.
And after receiving the MQTT message, other second user terminals analyze the MQTT message. When the message instruction is an alarm reminding service, the user can be reminded by popping up the frame and then informed. When the device information updating service is used, the cloud interface is triggered and called to refresh the current page data, so that the consistency of the device information of the local target APP page and the target APP page of another control device is ensured, the purpose of information synchronization is achieved, and the user experience is improved.
Further, referring to fig. 3, a schematic flow chart of a scheme for synchronizing attribute information of the intelligent terminal based on MQTT is shown.
The method comprises the following steps: after logging in the APP, a user initializes the MQTT service, subscribes the MQTT message by taking a/CID/i (which can be agreed according to the situation and is based on CID) as a theme, and monitors the MQTT message published by the theme in real time if the subscription is successful. When the CID is used for logging in by the user, the cloud generates a character string with unique identification on the basis of the user information, and the character string is used as a unique identification of the user at the cloud.
Secondly, the step of: after the user adopts the APP to control/manage the equipment, the interface can be updated in real time, and the interface is reported to the cloud end interface in real time to push, so that other users related to the equipment are reminded. For example: device information updates, service triggered alert alerts, etc.
③: and after the cloud receives and reports, the user information associated with the equipment is acquired from the Redis database through the unique equipment identifier.
Fourthly, the method comprises the following steps: and if the relevant user information of the intelligent equipment is not acquired in the Redis database, acquiring the user information from the Mysql database.
Fifthly: after the user information is obtained, the service data (including specific service processing instructions such as alarm reminding, equipment information updating and the like) is packaged, and the MQTT message is issued according to the theme of d/CID/i. At this point, a message is pushed to both the associated users of the device.
Sixthly, the method comprises the following steps: the associated user monitors the MQTT message of the current user theme as described in the first step, and once the theme message of the current user is pushed by the cloud, the associated user can immediately receive the MQTT push message at the APP terminal. And after receiving the message, analyzing the message. When the message instruction is an alarm reminding service, the user can be reminded by popping up the frame and then informed. When the device information updating service is used, the cloud interface is triggered and called to refresh the current page data, so that the information of the device information of the current page is ensured to be consistent with the information of the APP management page of another control device, the purpose of information synchronization is achieved, and the user experience is improved.

after the first user terminal controls and processes the target intelligent terminal based on the target APP, updating attribute information of the target intelligent terminal related to control and processing operation in the local target APP;
the first user terminal calls a cloud interface and reports the recently updated attribute information of the target intelligent terminal to a cloud;
the cloud determines other second user terminals bound with the target intelligent terminal, and sends the attribute information to the other second user terminals in an MQTT message;
and after receiving the MQTT message, the other second user terminals respectively update and synchronize the attribute information of the target intelligent terminal in the local target APP.
7. The system for synchronizing attribute information of intelligent terminals based on MQTT according to claim 6, wherein the first user terminal, when initializing message queue telemetry transmission MQTT services deployed among all user terminals installed with the target APP, is specifically configured to:
subscribing to an MQTT service based on the user information of the first user terminal, wherein the MQTT service is deployed among all user terminals installed with the target APP, and the user information at least includes: and (4) identifying the user.
8. The system for synchronizing the attribute information of the intelligent terminal based on the MQTT according to claim 6, wherein a Redis database and a Mysql database are further deployed at the cloud; when determining other second user terminals bound to the target intelligent terminal, the cloud is specifically configured to:
based on the unique identifier of the target intelligent terminal corresponding to the received attribute information, searching whether other user identifiers related to the unique identifier exist in a Redis database;
if the user terminal corresponding to the other user identification is found in the Redis database, determining the user terminal corresponding to the other user identification as other second user terminals;
if the unique identifier is not found in the Redis database, further searching whether other user identifiers related to the unique identifier exist in the Mysql database; and if the user terminal corresponding to the other searched user identifier is found in the Mysql database, determining the user terminal corresponding to the other searched user identifier as the other second user terminal, and if the user terminal is not found in the Mysql database, not processing the user terminal.
9. The system for synchronizing the attribute information of the intelligent terminals based on the MQTT according to any one of claims 6 to 8, wherein the attribute information of the target intelligent terminal at least comprises:
alarm information, equipment state update information and fault information.
10. The MQTT-based system for synchronizing the attribute information of the smart terminal according to claim 6, wherein the cloud, when sending the attribute information to the other second user terminals in MQTT messages, is specifically configured to:
performing service data encapsulation based on an operation instruction corresponding to the service processing content contained in the attribute information;
and issuing the MQTT message obtained after encapsulation to the other second user terminals.
