     DETAILED DESCRIPTION 
     The disclosure will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of some embodiments are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed. 
     The present disclosure provides, inter alia, a data push method, a data push system, and a computer-program product that substantially obviate one or more of the problems due to limitations and disadvantages of the related art. In one aspect, the present disclosure provides a data push method. In some embodiments, the data push method includes publishing data by at least one of a plurality of data publishing terminals; communicating an intelligent gateway with the plurality of data publishing terminals to monitor data publishing status of the plurality of data publishing terminals; communicating the intelligent gateway with a cloud-based data distribution broker configured to implement) publish-and-subscribe protocol via internet to transmit data published by the plurality of data publishing terminals to the cloud-based data distribution broker via the publish-and-subscribe protocol; and performing a controllable operation by one or more of a plurality of device terminals based on the data transmitted to the one or more of a plurality of device terminals. Optionally, the cloud-based data distribution broker includes a message proxy server, a background management system, a database server, an application server, and an object storage server. Optionally, the intelligent gateway is configured to transmit the data published by the plurality of data publishing terminals to the message proxy server via the publish-and-subscribe protocol. Optionally, the plurality of data publishing terminals comprise a mobile terminal and a stationary terminal. Optionally, the mobile terminal is configured to publish the data in real time. 
       FIG.  1    is a schematic diagram illustrating a data push system in some embodiments according to the present disclosure. Referring to  FIG.  1   , the data push method in some embodiments includes a cloud-based data distribution broker PSB configured to implement a publish-and-subscribe protocol. Examples of publish-and-subscribe protocol include a Message Queue Telemetry Transport (MQTT) publish-and-subscribe protocol. MQTT is a lightweight client/server messaging protocol based on a publish-and-subscribe interaction rather than client-request and server-deliver model. Under the publish-and-subscribe model, a client publishes information to the cloud-based data distribution broker PSB. The information published by a client is identified under one of a number of ‘topics,’ and other clients subscribe to the relevant topic and receive the information from the broker when the information is newly published or updated. Utilizing this publish-and-subscribe model, clients are able to publish data items they “know about,” and clients are able to subscribe to data “known about” by other clients. In particular, the clients can subscribe specifically to those “topics” that are relevant to their own operation. 
     Referring to  FIG.  1   , the clients in the publish-and-subscribe model may include a plurality of data publishing terminals PT, and a plurality of device terminals DT. In one example, the plurality of data publishing terminals PT are clients that publish data to the MQTT broker, and the plurality of device terminals DT are clients that subscribe to the data. However, the plurality of data publishing terminals PT are not limited to data-publishing clients, and the plurality of device terminals DT are not limited to data-subscribing clients. Referring to  FIG.  1   , the plurality of data publishing terminals PT may subscribe to “topics” relevant to their own operation, and the plurality of device terminals DT may also publish data items that they “know about.” In one example, the plurality of data publishing terminals PT includes a mobile terminal MPT (e.g., a smart phone) and a stationary terminal SPT (e.g., a desktop computer). 
     In some embodiments, the plurality of data publishing terminals PT are data generating units. Examples of data generating units include automatic data generating units and manual data generating units. Examples of manual data generating units include the mobile terminal MPT and the stationary terminal SPT. Manual data generating units include a user interface for inputting data. Examples of automatic data generating units include active data generating units and passive data generating units. Examples of active data generating units include various sensors and detectors, e.g., temperature sensors, pressure sensors, humidity sensors, cameras, and closed-circuit television. Examples of passive data generating units include radio-frequency identification readers. 
       FIG.  2    is a schematic diagram of a data push system in some embodiments according to the present disclosure. Referring to  FIG.  2   , the data push method in some embodiments include publishing data by at least one of a plurality of data publishing terminals PT; communicating an intelligent gateway IG with the plurality of data publishing terminals PT to monitor data publishing status of the plurality of data publishing terminals PT; communicating the intelligent gateway IG with a cloud-based data distribution broker PSB configured to implement a publish-and-subscribe protocol via internet to transmit data published by the plurality of data publishing terminals PT to the cloud-based data distribution broker PSB via the publish-and-subscribe protocol; and performing a controllable operation by one or more of a plurality of device terminals DT based on the data transmitted to the one or more of a plurality of device terminals DT. Optionally, the plurality of data publishing terminals PT include a mobile terminal MPT and a stationary terminal SPT. The mobile terminal MPT is configured to publish the data in real time. 
     In some embodiments, the cloud-based data distribution broker PSB includes a message proxy server. Optionally, the intelligent gateway IG is configured to transmit the data published by the plurality of data publishing terminals to a message proxy server of the cloud-based data distribution broker PSB via the publish-and-subscribe protocol. Examples of intelligent gateways include various edge computing gateways, such as the Hewlett Packard Enterprise EL20, the Intel DK300, and Dell IoT Gateway 5500. Examples of message proxy server include Apache ActiveMQ (The Apache Software Foundation), mosquito, moquette, and emqttd. 
       FIG.  3    is a schematic diagram illustrating the structure of a cloud-based data distribution broker in some embodiments according to the present disclosure. Referring to  FIG.  3   , in some embodiments, the cloud-based data distribution broker PSB includes the message proxy server include MPS, and further includes at least one of a background management system BMS, a database server DS, an application server AS, or an object storage server OSS. The background management system BMS manages various databases and servers. In one example, the background management system BMS is configured to manage the configuration of the cloud-based data distribution broker PSB, for example, the configuration of the message proxy server MPS. In another example, the background management system BMS configures the IP address of the message proxy server include MPS and a registered proxy mode of the message proxy server include MPS. The database server DS is configured to run a database and store metadata. In one example, the database is a MySQL database, and the database server DS is configured to run the MySQL database. The application server AS is configured to provide various business logics to client applications through various protocols, and provide access to the business logics for the client applications&#39; use. In one example, the application server AS is configured to implement functions including device list, recharging service, map service, SMS service, and domain name service. The object storage server OSS is configured to store and process discrete units. 
     In one example, the intelligent gateway IG monitors the data publishing status of the plurality of data publishing terminals PT, receives the data transmitted from one or more of the plurality of data publishing terminals PT, filters and checks the request. The application server AS is configured to process and store the data, for example, saving metadata in the database servers DS and saving multimedia data in the object storage server OSS. In another example, the application server AS is configured to push the data to a message push server, which in turn pushes the data to one or more of the plurality of device terminals DT. 
       FIG.  4    is a schematic diagram of a data push method in some embodiments according to the present disclosure. Referring to  FIG.  4   , the data push method in some embodiments includes transmitting the data to the intelligent gateway IG. The intelligent gateway IG is configured to determine whether the data is published by the mobile terminal MPT. When the intelligent gateway IG determines that the data is published by the mobile terminal MPT, the intelligent gateway IG is further configured to determine whether the mobile terminal MPT and a selected device terminal of the plurality of device terminals DT are connected to a same local area network. As shown in  FIG.  4   , in one example, a first device terminal DT 1  of the plurality of device terminals DT and the mobile terminal MPT are connected to the same local area network (depicted as LAN in  FIG.  4   ). Based on a determination that the mobile terminal MPT and the selected device terminal are connected to the same local area network, the intelligent gateway IG instructs the mobile terminal MPT to transmit the data from the mobile terminal MPT directly to the selected device terminal (in this case, the first device terminal DT 1 ) via the same local area network LAN, without going through the cloud-based data distribution broker PSB. 
     By configuring the intelligent gateway IG to determine whether the data is published by the mobile terminal MPT and whether the mobile terminal MPT and the selected device terminal of the plurality of device terminals DT are connected to a same local area network, the present method can greatly expedite the transmission of the data. The present method provides flexibility and efficiency to the data push process. 
       FIG.  5    is a schematic diagram of a data push method in some embodiments according to the present disclosure. Referring to  FIG.  5   , the data push method in some embodiments includes transmitting the data to the intelligent gateway IG. The intelligent gateway IG is configured to determine whether the data is published by the mobile terminal MPT. When the intelligent gateway IG determines that the data is published by the mobile terminal MPT, the intelligent gateway IG is further configured to determine whether the mobile terminal MPT and a selected device terminal of the plurality of device terminals DT are connected to a same local area network. As shown in  FIG.  5   , in one example, none of the plurality of device terminals DT is connected to a same local area network as the mobile terminal MPT. For example, the mobile terminal MPT and all of the plurality of device terminals DT are connected through a wide area network WAN. Based on a determination that the mobile terminal MPT and the selected device terminal (in this case, any one of the plurality of device terminals DT) are not connected to the same local area network, the intelligent gateway IG is configured to transmit the data from the intelligent gateway IG to the message proxy server MPS (see  FIG.  3   ) via the publish-and-subscribe protocol. 
     By configuring the intelligent gateway IG to determine whether the terminal publishing the data and the selected device terminal of the plurality of device terminals are connected to a same local area network, the present data push method enables an option of pushing data using the cloud-based data distribution broker PSB via the publish-and-subscribe protocol. The cloud-based data distribution broker PSB makes it possible to push data even if one or more of the plurality of device terminals DT are in a poor network environment, thereby avoiding delay and information loss. 
       FIG.  6    is a schematic diagram of a data push method in some embodiments according to the present disclosure. Referring to  FIG.  5   , the data push method in some embodiments includes transmitting the data to the intelligent gateway IG. The intelligent gateway IG is configured to determine whether the data is published by the mobile terminal MPT. When the intelligent gateway IG determines that the data is published by the mobile terminal MPT, the intelligent gateway IG is further configured to determine whether the mobile terminal MPT and a selected device terminal of the plurality of device terminals DT are connected to a same local area network. Optionally, the intelligent gateway IG is further configured to determine one or more device terminals of the plurality of device terminals DT that subscribe to a topic published by the mobile terminal MPT. In one example, the intelligent gateway IG determines that a first device terminal DT 1  and a second device terminal DT 2  of the plurality of device terminals DT subscribe to the topic. In another example, the intelligent gateway IG determines that the first device terminal DT 1  and the mobile terminal MPT are connected to the same local area network (depicted as LAN in  FIG.  6   ), and the second device terminal DT 2  and the mobile terminal MPT are not connected to the same local area network. In some embodiments, based on a determination that the mobile terminal NPT and a first selected device terminal (in this case, the first device terminal DT 1 ) of the plurality of device terminals DT are connected to the same local area network (depicted as LAN in  FIG.  6   ), the intelligent gateway IG instructs the mobile terminal MPT to transmit the data from the mobile terminal MPT directly to the selected device terminal (in this case, the first device terminal DT 1 ) via the same local area network LAN, without going through the cloud-based data distribution broker PSB. In some embodiments, based on a determination that the mobile terminal MPT and a second selected device terminal (in this case, the second device terminal DT 2 ) of the plurality of device terminals DT are not connected to the same local area network, the intelligent gateway IG is configured to transmit the data from the intelligent gateway IG to the message proxy server MPS (see  FIG.  3   ) via the publish-and-subscribe protocol; and the cloud-based data distribution broker PSB pushes the data to the second selected device terminal (in this case, the second device terminal DT 2 ).
