Before formally introducing the embodiments of the present application, the scenarios to which the present application is applied and the problems existing in the scenarios will be described with reference to the accompanying drawings. For example, Figure 1 is a schematic diagram of the application scenario provided by this application, as shown in Figure 1, this application is applied in the scenario of Message Queuing Telemetry Transport (MQTT for short), as shown in Figure 1 MQTT communication The system specifically includes: a first device, a server and at least one second device, wherein the first device can perform MQTT communication with the at least one second device through the server.

Fig. 2 is a schematic diagram of an MQTT communication method. The communication method shown in Fig. 2 can be applied to the MQTT communication system shown in Fig. 1. In the P1 part of the communication method, in order to carry out MQTT communication, it is first necessary to carry out equipment To connect with the server, establish an MQTT connection between the first device and the server through S11, and establish an MQTT connection between the second device and the server through S12. After the P1 part, MQTT communication can be performed between the first device and the second device through the server.

Exemplarily, when the MQTT communication system shown in Figure 1 is applied to IoT scenarios such as smart homes, the user needs to establish an MQTT communication connection with the server through S12 through After the first device such as the mobile phone carried by the user establishes an MQTT communication connection with the server. The user can use the MQTT communication between the first device and the second device in the home, so as to realize the smart home function that the user obtains the dynamics in the home and controls the devices in the home.

In some embodiments, among two devices performing MQTT communication, the device sending MQTT data may be called a "publisher", and the device receiving MQTT data may be called a "subscriber". In the P2 part shown in Figure 2, the first device can serve as a publisher and send the first MQTT data to the server in S21, so that the server sends the first MQTT data to at least one second device as a subscriber in S22 . In the P3 part shown in Figure 2, the first device can act as a subscriber. After the second device sends the second MQTT data to the server in S31, the MQTT service sends the second MQTT data to the first device in S32 .

However, in the MQTT communication method shown in Figure 2, before the device performs MQTT communication, it needs to perform MQTT connection according to the usage of the user, especially when the first device is a device such as a mobile phone carried by the user, often Due to signal coverage, application settings in the mobile phone, etc., the connection to the server is disconnected, so that the user needs to manually connect every time MQTT communication is required, resulting in insufficient intelligence of the device when performing MQTT communication, and due to user The steps required to manually make an MQTT connection are cumbersome, time-consuming, and inefficient, which in turn reduces the communication efficiency for MQTT communication between devices.

Therefore, the present application provides an MQTT communication method, device, electronic equipment, and storage medium to solve the technical problem of insufficient intelligence of the equipment during MQTT communication, to reduce the number of MQTT connections manually performed by the user, and to improve the efficiency of the equipment when performing MQTT communication. The degree of intelligence improves the communication efficiency of MQTT communication between devices. The technical solution of the present application will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 3 is a schematic flow diagram of an embodiment of the MQTT communication method provided by the present application. The MQTT communication method shown in FIG. 3 can be applied to the MQTT communication system shown in FIG. 1 , specifically, including:

S101. The first device determines its geographic location.

In some embodiments, the first device may specifically determine its geographic location by means of an AutoNavi Fused Location Provider (FLP for short). Among them, the first device with integrated positioning service function integrates multiple positioning methods including Global Positioning System (Global Positioning System, GPS) positioning, base station positioning, Wi-Fi positioning, Bluetooth positioning and sensor positioning at its system layer. Therefore, the geographic location of the first device is jointly determined through the fusion of multiple positioning results, which can realize indoor and outdoor integration and precise positioning under different motion states. The determined geographic location may be identified by latitude and longitude coordinates, etc., and different geographic locations have different latitude and longitude coordinates.

S102: When the geographic location determined in S101 satisfies the first preset condition, and the current first device does not establish a connection with the server, the first device establishes an MQTT connection relationship with the server. This application does not limit the specific implementation of establishing an MQTT connection between the first device and the server. For example, the first device may send a connection establishment request to the server. After receiving the request, the server sends a connection establishment response to the first device. Establishment of MQTT connection, etc.

S103: Perform MQTT communication between the first device and the server through the MQTT connection established in S102. Wherein, the MQTT communication includes: the first device sends the first MQTT data to the server, so that the server sends the first MQTT data to at least one second device; or, the first device receives the second MQTT data sent by the server, and the second The MQTT data is sent by the second device, and after the first device establishes a connection with the server, the server sends the second MQTT data to the first device.

In some embodiments, the first preset condition includes: the distance between the geographic location and the first preset location is smaller than a first threshold. For example, the first preset location may be the location of his home specified by the user in advance, and the first threshold may be 10 meters, 50 meters, 100 meters, etc., when the distance between the geographic location and the first preset location is less than the first threshold , indicating that the user brings the first device close to the first preset location, and may connect to the server and perform MQTT communication. At this time, the first device "automatically" establishes an MQTT connection relationship with the server without any operation by the user, and can then use the established MQTT connection relationship to perform MQTT communication.

For example, when the user is carrying the first device on the way home, when the first device determines that the distance between its geographic location and the first preset location in the home is less than the first threshold through FLP, the first device establishes an MQTT connection relationship between servers. Subsequently, the first device may send the control command to the second device stored by the user in advance as the first MQTT data to the server, so that the server sends the first MQTT data to the corresponding second device, so that the second device receives the first After the MQTT data, execute the control command stored in the first device in advance by the user. The control command may be a command to turn on smart devices such as air conditioners and purifiers, a mode adjustment command, and the like. And, the first device can also receive the second MQTT data sent by the server from the second device. The second MQTT data can be the data collected by the second device such as the temperature and humidity sensor and camera in the user's home, so that the first device can send The user presents a real-time scene at home. Therefore, before the user returns home, and without the user operating the first device to establish an MQTT connection, the first device has automatically established a connection with the server and performed MQTT communication.

In another example, when the first device is a smart bracelet carried by a patient, and the distance between the smart bracelet and the first preset position detected from the hospital is less than the first threshold, the relationship between the smart bracelet supervisor and the server The MQTT connection relationship between them. Subsequently, the smart bracelet can send the detected patient's human body data such as heartbeat, blood pressure, temperature, etc. to the server as the first MQTT data, so that the server sends these human body data to the hospital database as the second device, so that the patient No further baseline measurements are required upon arrival at the hospital. And, the smart bracelet can also receive the second MQTT data sent by the hospital database through the server, the second MQTT data can include the basic information of the hospital, medical information, flow information, etc. In the case of a device, the interaction between the smart bracelet and the hospital database based on MQTT communication for patient information and hospital information is realized. Or, when the first device is the patient's smart bracelet, after the smart bracelet detects that it is on the ambulance, regardless of whether the geographical location meets the first preset condition, it will automatically establish an MQTT connection and perform MQTT Communication, realize the interaction of patient information and hospital information between the smart bracelet and the hospital database in advance.

In some other embodiments, the first preset condition includes: the distance between the geographic location and the second preset location is greater than a second threshold. For example, the second preset location may be the location of his home specified by the user in advance, and the second threshold may be 10 kilometers, 20 kilometers, etc. When the distance between the geographic location and the second preset location is greater than the second threshold, it means that the user Carrying the first device away from the second preset location, in order to prevent accidents, the first device can actively connect to the server and perform MQTT communication, and send the geographic location of the first device to the second device at home through MQTT communication, so that The family was able to confirm its location. At this time, the first device may also "automatically" establish an MQTT connection relationship with the server without any operation by the user, and then use the established MQTT connection relationship to perform MQTT communication.

In some embodiments, after the first device establishes an MQTT communication connection with the service as shown in FIG. After the first location satisfies the second preset condition, the first device disconnects the MQTT communication connection with the server. For example, the second preset condition may be that the distance between the geographic location and the fourth preset location is greater than a fourth threshold, for example, the fourth preset location may be the location of the user's home specified in advance, and the fourth threshold may be 10 meters, 50 meters, etc. The first device takes the temperature control module at home as an example. When it is placed at home and the distance from the fourth preset position is less than the fourth threshold, the first device maintains the MQTT communication connection with the server; when it is moved away from home, it cannot continue In normal use, when the geographical position detected by the first device and the fourth preset position are greater than the fourth threshold, the first device actively disconnects the MQTT communication connection to reduce the invalid MQTT communication connection and data of the first device. Interactive, save power consumption.

It should be noted that the MQTT communication performed by the first device in the above example is only an example, and this application does not limit the MQTT-related operations performed after the first device establishes an MQTT connection with the server. For example, MQTT-related operations such as publishing, subscribing, and unsubscribing in MQTT communication may also be included.

To sum up, in the MQTT communication method provided by this embodiment, after the first device detects that its geographic location meets the first preset condition, it establishes an MQTT connection with the server; thus, MQTT communication can be performed through the MQTT connection; and After the geographic location satisfies the second preset condition, disconnect the MQTT connection with the server. The user of the first device can automatically establish an MQTT connection and perform MQTT communication, or disconnect the MQTT connection more intelligently without manual operation and settings, thereby reducing the need for the user of the first device to perform MQTT The operations required for communication and the time consumed during operation improve the intelligence of the device when performing MQTT communication, thereby improving the communication efficiency during MQTT communication between devices, and also improving the user experience of devices performing MQTT communication.

In the embodiment of the present application, the specific communication method when establishing an MQTT connection between the first device and the server is not limited. Establish an MQTT connection. The GPRS network may specifically be a 4G network, a 5G network, and the like. Alternatively, the first device may also establish an MQTT connection with the server through a wireless fidelity (Wireless Fidelity, Wi-Fi for short) network.

In some embodiments, when the first device establishes an MQTT connection with the server through the Wi-Fi network, before establishing the MQTT connection, if the Wi-Fi service of the first device is not enabled, the first device may first enable the Wi-Fi service .

In some embodiments, when the first device establishes an MQTT connection with the server through the Wi-Fi network, the user can connect the first device to the Wi-Fi access point (Access Point, referred to as: AP) used by the Wi-Fi network It is configured so that the storage unit of the first device stores AP information near different geographic locations in advance. Then when the distance between the geographic location of the first device and the stored geographic location is smaller than the first threshold, the first device can directly determine the AP information corresponding to the geographic location from the storage unit, and according to the Wi-Fi network provided by the AP and the The server establishes an MQTT connection. It can be understood that the storage unit of the first device can store multiple geographic locations and the AP information corresponding to each geographic location information, so that the first device can establish APs based on AP information in different geographic locations through pre-configured APs. MQTT connection, so as to further improve the intelligence and automation of the first device to establish the MQTT connection, and further improve the communication efficiency of the device when performing MQTT communication.

Further, the first device provided in the embodiment of the present application can not only connect and disconnect the MQTT connection according to the geographical location, but also switch between the publisher mode and the subscriber mode according to the geographical location, so as to realize a more flexible MQTT communication. For example, when the first device determines that the distance between its geographic location and the third preset location is less than the third threshold, it will perform MQTT communication in publisher mode and actively send the first MQTT data to the server; when the first device determines that its geographic location If the distance between the location and the third preset location is greater than the third threshold, the MQTT communication is performed in the subscriber mode, and the second MQTT data sent by the server from the second device is received. For example, if the first device is a wristband carried by a participant, when the first device is in the venue and the distance from the third preset position in the venue is less than the third threshold, the first device sends a message to the venue in publisher mode. The management server sends the information of the participants; when the first device leaves the venue and the distance from the third preset position in the venue is greater than the third threshold, the first device receives the conference information sent by the management server in the venue in subscriber mode .

In the aforementioned embodiments of the present application, the first device can automatically establish an MQTT connection and perform MQTT communication according to the geographic location, while in other embodiments, after the server establishes the MQTT connection, the first device can also use ringing, vibration Send a prompt message in the form of other forms, prompting the user that the MQTT connection has been established. Subsequently, after receiving the user's instruction information, the first device performs corresponding MQTT communication according to the user's instruction information, thereby improving the controllability of MQTT communication, and performing MQTT communication strictly according to the user's instruction.

In some embodiments, based on the fact that the first device can obtain its geographic location in the form of FLP, when the geographic location obtained by the first device within the preset time period, the location of the first device within the preset time period can be obtained. Therefore, the first device can determine the MQTT data to be sent to the server according to the current moving speed, and finally send the MQTT data corresponding to the moving speed to the server. That is, the MQTT data is related to the moving speed of the first device. For example, when the user walks home with the first device, and when the first device determines that the distance from the first preset location in the home is less than the first threshold and the moving speed is lower than the preset speed according to the geographic location, the second A device can send a mid-range mode control command to the home air purifier through MQTT communication; and when the user takes the first device home by car, the first device determines the distance from the first preset location in the home according to the geographic location When the speed is less than the first threshold and the moving speed is greater than the preset speed, the first device can send a high-end mode control command to the home air purifier through MQTT communication, so as to complete the air purification faster. Through this embodiment, on the basis of establishing an MQTT connection according to the location information, the first device performs different MQTT communications according to the moving speed of the first device, such as sending different MQTT data, which further enriches the application scenarios of this embodiment and the second The functions of a device, and further reduce the settings that users need to make, replace the user's selection of MQTT data, improve the intelligence of the device when performing MQTT communication, thereby improving the communication efficiency of MQTT communication between devices, and also Improved user experience for devices communicating with MQTT.
