Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In some of the flows described in the specification and claims of this application and in the above-described figures, a number of operations are included that occur in a particular order, but it should be clearly understood that these operations may be performed out of order or in parallel as they occur herein, the number of operations, e.g., 101, 102, etc., merely being used to distinguish between various operations, and the number itself does not represent any order of performance. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different.

The technical scheme is mainly applied to the Internet of things (IoT) scene to realize remote control of the IoT terminal, and of course, the technical scheme can also be applied to other application scenes needing to remotely control any terminal.

Taking an IoT scenario as an example, an IoT terminal is usually an edge node of an IoT system, deployed in a remote place. In many practical applications, the IoT terminal needs to be remotely controlled, for example, many intelligent terminals are used as the IoT terminal in a new retail scene, such as an offline large screen, an intelligent container, a POS machine, and the IoT terminal needs to be remotely operated and maintained to solve a problem that the IoT terminal may have. As described in the background art, the existing methods all use a wired connection method, for example, the IoT terminal is connected through a USB (Universal Serial Bus) data line, which requires complicated wiring, increases control difficulty for the IoT terminal deployed at a remote location, and has no universality.

In order to improve the simplification of a remote control mode and the universality of remote control, the inventor provides the technical scheme of the application through a series of researches. In an embodiment of the present application, a control system is provided, which comprises at least one proxy server, a web (web page) server, at least one terminal, and a client; the client responds to the selection operation aiming at the at least one terminal, determines a selected target terminal and sends a control request to the web server; the web server allocates a target proxy server and a network port address of the target proxy based on the control request; feeding back the network port address to the target terminal and the client; the target proxy server establishes connection with the target terminal and the client respectively based on the network port address; determining a debugging port address of the target terminal, and establishing a port mapping relation between the debugging port address and the network port address; establishing a network channel between the client and the target terminal based on the port mapping relation; the client can remotely control the target terminal through the network channel. By adopting a wireless connection mode, the remote control is realized through a wide area network, the remote control difficulty is reduced, and the remote control universality is improved.

In the embodiment of the application, the port mapping is carried out through the proxy server, so that the client can access the debugging port of the terminal, and the terminal can be remotely controlled. Although the terminal can be accessed to the internet in the scene of the internet of things, the terminal can only transmit messages, cannot access a debugging port of the terminal, and cannot realize higher-level remote control. Even if the terminal is located in the local area network, the intranet penetration can be realized by carrying out port mapping through the proxy server, and therefore the remote control of the terminal can be realized through the wide area network.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic structural diagram of an embodiment of a control system provided in an embodiment of the present application, where the control system may include at least one proxy server 101, a web server 102, a client 103, and at least one terminal 104.

When at least one proxy server comprises a plurality of proxy servers, a proxy server cluster is formed. In fig. 1, only one proxy server and one terminal are drawn for convenience of understanding.

The client 103 is used for responding to the selection operation of the at least one terminal, determining a selected target terminal 104 and sending a control request to the web server 102;

the web server 102 is configured to allocate network port addresses of the target proxy server 101 and the target proxy 101 based on the control request; feeding back the network port address to the target terminal 104 and the client 103;

the target proxy server 101 is configured to establish connections with the target terminal 104 and the client 103 based on the network port address; determining a debugging port address of the target terminal 104, and establishing a port mapping relation between the debugging port address and the network port address; establishing a network channel between the client 103 and the target terminal 104 based on the port mapping relationship;

the client 103 is configured to remotely control the target terminal 104 through the network channel.

In an IoT scenario, the at least one terminal may be an IoT terminal, and the web server may be a server that the at least one IoT terminal accesses to the internet, and in the IoT scenario, the IoT terminal generally establishes an mqtt connection with the web server through an mqtt (Message queue telemetry Transport) protocol, but the mqtt connection can only perform Message passing, and the web server cannot directly access a debug port of the IoT terminal, so that remote control of the IoT terminal cannot be achieved.

Http (hypertext transfer protocol) and hypertext transfer protocol) connection is established between the client 103 and the web server 104, the web server 104 may send a control page to the client 103, the control page may include control prompt information of the at least one terminal, and the client 103 displays the control page. The selection operation for the at least one terminal may specifically refer to a selection operation for at least one control guidance message, so that the corresponding target terminal 104 may be determined according to the selected control guidance message. The target terminal 104 is any terminal that the user wants to remotely control.

The client 103 may be a browser (web browser), an application installed in the electronic device, or the like.

After the web server 102 receives the control request, it may determine the target proxy server 101, and when the system includes only one proxy server, the one proxy server is the target proxy server, and when the system includes a plurality of proxy servers, any one of the proxy servers that is idle or has a small load may be selected as the proxy server. Network ports may be allocated after the target proxy server is determined, and an unused port of the target proxy server may be selected as a network port, thereby obtaining a network port address. Alternatively, the network port address may include an ip address of the destination proxy server, a port number of the network port, and the like.

The web server 102 may respectively feed back the allocated network port addresses to the target terminal 104 and the client 103, and optionally, the target terminal 104 may issue a debugging instruction including the network port addresses, and issue a connection instruction including the network port addresses to the client 103.

The target terminal 104 may thus request to establish a connection with the target proxy server 101 based on the network port address in response to the debug instruction; the client 103 may request to establish a connection with the target proxy server 101 based on the network port address in response to the connection instruction.

Specifically, after the target terminal 104 obtains the debug instruction, it may determine a debug port, which is a non-80 port, so as to implement remote control of the target terminal through access to the debug port. The target terminal 104 may send a first connection request to the target proxy server 101, where the first connection request may include the debug port address of the target terminal 104 and the network port address. The target proxy server 101 thus establishes a port connection with the target terminal 104 based on the debug port address and the network port address. Optionally, the port connection established between the target proxy server 101 and the target terminal 104 is specifically a socket connection, and the debug port may be accessed through the socket connection.

The client 103 may send a second connection request including the network port address of the target terminal 104 to the target proxy server 101, and the client may establish a socket connection with the target proxy server 101 using the temporary port so that the network port may be accessed through the socket connection.

When the client is deployed in the electronic device of the Android system, the client can be connected with the target proxy server through an adb (Android Debug Bridge) tool.

Since the web server cannot directly access the debug port of the IoT terminal in the IoT scenario, the remote control of the IoT terminal cannot be realized. That is, the web server can perform message transmission with the terminal, but cannot implement remote control, and the terminal is located in the local area network, so that the proxy server is adopted, the proxy server adopts an intranet penetration technology, and address conversion is implemented through port mapping, so as to establish a network channel between the client and the terminal.

Therefore, in this embodiment of the present application, the target proxy server 101 establishes a port mapping relationship between the debug port address and the network port address, so that when the client 103 accesses the network port, the client forwards the debug port based on the port mapping relationship, thereby implementing access of the client to the debug port of the client 103, and further implementing remote control on the target terminal 104.

The proxy server can be embodied as an intranet-penetrating server, an intranet-penetrating client can be operated in the terminal, and the proxy server can realize that the client accesses the target terminal and the target terminal accesses the client through port mapping.

Optionally, intranet penetration may be implemented by using an frp technology, the proxy server may be an frp server, and the frp client is operated in the terminal, which may be implemented.

In the embodiment, the remote control of the terminal through the wide area network is realized through the proxy server, the wired connection is not needed, the remote control difficulty is reduced, the proxy server can be suitable for the terminal deployed in any area, and the universality of the remote control is improved.

In practical applications, the remote control of the target terminal may include acquiring service data or log information of the target terminal, and controlling the target terminal to perform corresponding operations, such as starting or closing an application program on the terminal.

In addition, the remote control of the target terminal can be usually realized through a screen operation event, that is, the screen information of the target terminal is synchronously displayed, and the corresponding control of the target terminal is realized through the screen operation event of the screen information.

Therefore, in some embodiments, the client performing remote control on the target terminal through the network channel may include:

acquiring screen information sent by the target terminal through the network channel;

displaying the screen information;

detecting a screen operation event aiming at the screen information, and generating a corresponding control instruction;

and sending the control instruction to the target terminal through the network channel so that the target terminal can execute the control instruction to realize corresponding control.

For example, the screen operation event is a click event, the click event may be represented as (X, Y, action-click), and the generated control command may be to issue a click event to the coordinates of the screen (X, Y) by parsing the click event, or, for example, the screen operation event is a slide event (X1, Y1, X2, Y2, predetermined duration, action-slide), and the generated control command may be that it takes a predetermined duration from the screen (X1, Y1) to (X2, Y2) when the screen operation event is a slide event (X1, Y1, Y2).

The remote control of the target terminal can be realized through a target proxy server, namely the target proxy server is used for receiving related data sent by a client, and determining an actually accessed debugging port based on a port mapping relation, so as to forward the debugging port to the target terminal; or receiving related data sent by the target terminal, determining a client accessing the network port address based on the port mapping relation, and forwarding the client to the client.

Therefore, in some embodiments, the obtaining, by the client, the screen information of the target terminal through the network channel may specifically be receiving, by the target proxy server, the screen information sent by the target terminal and forwarded based on the port mapping relationship; and displaying the screen information.

That is, the target terminal is used for sending the screen information to the target proxy server, and the target proxy server forwards the screen information to the client based on the port mapping relation.

The screen information sent by the target terminal may be a video generated by capturing a screen of the target terminal in real time, and optionally, in order to reduce the data volume, the screen capture obtained by capturing the screen in real time may be converted into a video in an h.256 (video coding standard) format.

The sending, by the client, the control instruction to the target terminal through the network channel may specifically be sending the control instruction to the target proxy server, so that the proxy server forwards the control instruction to the target terminal based on the port mapping relationship.

For convenience of understanding, fig. 2a and 2b show schematic diagrams of remote control through a network channel, in fig. 2a, a target terminal 104 sends screen information to a client 103 through a target server 101; in fig. 2b, the client 103 sends a control command to the target terminal 104 via the target server 101.
