The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems with reference to the drawings and specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 3 is an interaction flow chart of a first data transmission method according to an embodiment of the present application, as shown in fig. 3, including the following steps:

Step S301: the control terminal selects a target port from part or all ports of the electronic equipment, and sends a first request containing controlled information and first check information to the target port.

In this embodiment, the control end and the corresponding controlled end may select the port of the connected electronic device according to the actual application scenario, where the port may be a port already connected to other control ends and controlled ends, or may be a port not yet connected to other control ends and controlled ends. I.e. the connection between the control end and the port, and the connection between the controlled end and the port are not fixed.

After selecting a target port from part or all ports of the electronic equipment, the control end sends a first request containing controlled information and first check information to the target port, and establishes connection between the control end and the port.

Referring to fig. 2, the control terminal 301 sends a first request including controlled information and a first check request to the port 1, and establishes a connection between the control terminal 301 and the port 1.

Step S302: the electronic equipment responds to a first request received through any port, and determines controlled information and first check information corresponding to the first request.

As described above, the first request includes the controlled information and the first check information; the controlled information characterizes which controlled end needs to be remotely controlled by the control end, the first check information needs to be used in subsequent check, and based on the first check information, the electronic equipment needs to determine the corresponding controlled information and the first check information after receiving the first request.

The controlled information is information capable of uniquely characterizing the controlled terminal, and in some optional embodiments, the controlled information includes an IP address of the controlled terminal, so that the electronic device can determine whether the controlled terminal is the controlled terminal corresponding to the controlled information as long as the electronic device receives the information sent by the controlled terminal, thereby accurately and efficiently determining the controlled terminal corresponding to the controlled information.

Step S303: the controlled terminal corresponding to the controlled information selects a target port from part or all ports of the electronic equipment, and sends a second request containing control information and second check information to the target port after the controlled terminal is connected with the target port.

In this embodiment, the controlled end may be remotely controlled by one or more control ends, so before performing the verification, the controlled end may be already connected to the target port, and at this time, the controlled end may directly send a second request to the target port; if the controlled end is not connected with the target port, a second request needs to be sent to the target port after the controlled end is connected with the target port.

Referring to fig. 2, a controlled terminal corresponding to the controlled information of the control terminal 301 is a controlled terminal 201; the controlled terminal 201 transmits a second request containing control information and second check information to the port 1, and the electronic device determines the corresponding control information and second check information in response to the second request.

The control information is information capable of uniquely characterizing the control end, and in some optional embodiments, the control information includes an IP address of the control end, so that the electronic device can determine whether the control end is the control end corresponding to the control information as long as receiving the information sent by the control end, thereby accurately and efficiently determining the control end corresponding to the control information.

Step S304: and if the electronic equipment determines that the control information is successfully matched with the control end, checking the first check information and the second check information, and after the first check information and the second check information pass the check, transmitting the data uploaded by the controlled end to the control end through the port.

Because the port of the electronic device may be connected with a plurality of control terminals and a controlled terminal, the electronic device needs to match the control terminal with the controlled terminal based on the control information to determine whether the controlled terminal needs to be controlled by the control terminal; and after the matching is successful, the first check information of the control end and the second check information of the controlled end are checked, and after the check is passed, the control end and the controlled end are successfully matched.

The following is a specific example:

The control terminal 301 sends a first request including the controlled information and a first check request to the port 1, and establishes a connection between the control terminal 301 and the port 1;

the controlled terminal corresponding to the controlled information of the control terminal 301 is the controlled terminal 201; after the controlled end 201 is connected with the port 1, a second request containing control information and second check information is sent to the port 1;

If the control end corresponding to the control information is the control end 301, the control end 301 and the controlled end 201 are successfully matched, the first verification information of the control end 301 and the second verification information of the controlled end 201 are continuously verified, and if the verification is successful, the remote control of the control end 301 on the controlled end 201 is established, namely, the electronic equipment sends the data uploaded by the controlled end 201 to the control end 301 through the port 1;

If the control end corresponding to the control information is the control end 302, the matching between the control end 301 and the controlled end 201 fails, and no subsequent verification is performed.

The above-mentioned data transmission process is only exemplary, and the present embodiment is not limited thereto.

As described above, the controlled end may be remotely controlled by one or more control ends, and referring to fig. 2, the control end 304 and the control end 305 both remotely control the controlled end 204 through the port 2; at this time, the electronic device sends the data uploaded by the controlled terminal 204 to the control terminal 304 and the control terminal 305 through the above-mentioned port 2, respectively.

In addition, the specific implementation manner of the first verification information and the second verification information is not limited in this embodiment, and is exemplary:

1) The first check information of the control end is the same as the second check information of the corresponding controlled end, such as the check information negotiated between the control end and the corresponding controlled end;

2) The first check information of the control end is obtained based on the second check information of the corresponding controlled end through a preset algorithm.

The implementation manner of the first verification information and the second verification information is only illustrative, and as long as the information that can realize verification between the control end and the corresponding controlled end can be used as the first verification information and the second verification information.

An embodiment of the present application provides an interactive flowchart of a second data transmission method, as shown in fig. 4, including the following steps:

Step S404: if the electronic equipment determines that the control information is successfully matched with the control end, determining whether the first check information is identical with the second check information; and if yes, the data uploaded by the controlled end are sent to the control end through the port.

As described above, in some embodiments, the first check information of the control end is the same as the second check information of the corresponding controlled end, based on which the electronic device needs to determine whether the first check information of the control end is the same as the second check information of the controlled end; if the first check information is the same as the second check information, the verification is passed, and remote control of the control end to the controlled end can be established; otherwise, if the first check information is different from the second check information, the check is not passed, and the remote control of the control end to the controlled end cannot be established.
