Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a schematic block diagram of a portion of an apparatus for interacting with computers within a subnet, also showing some components associated with the apparatus, with the subnet 1 represented by dashed boxes and components within subnet 1 not shown for simplicity, according to one embodiment of the present invention. In the present application, subnet 1 may contain multiple computers. The correspondence of reference numerals is as follows:
4. an interaction server; 5. a control instruction generating device; 20' video data lines; 20 ". video data line; 20 "'. a video data line; 30. a control command transmission line; 30' a unidirectional transmission line.
The device for interacting the computers in one subnet comprises an interaction server 4, a unidirectional transmission line (30') (or other unidirectional transmission equipment) and an instruction receiving server (not shown in the figure, and the network exposure environment of the original subnet is not changed after the instruction receiving server establishes connection with the computers in the subnet). According to some embodiments of the invention, the means for interacting with computers within a subnet may further comprise a plurality of video data lines 20 ', 20 ", 20"'. The number of video data lines 20 ', 20 ", 20"' is the same as the number of computers within the subnetwork 1, each video data line 20 ', 20 ", 20"' being connected to a respective computer within the subnetwork. The video data line may also be a plurality of other non-network transmission devices, i.e. devices that transmit content without the aid of a network, in order to avoid any risk due to the exposure of the transmission process to the network. The device and the components for performing interaction will be described in detail below with reference to the whole interaction process or the interaction method.
As shown by the arrow in the figure, the control instruction generating device 5 transmits a control instruction to the interactive server 4 through a control instruction transmission line 30 (such as a USB line, or other non-network transmission device), the interactive server 4 determines a computer to be controlled by the control instruction, and transmits the computer ID and the control instruction to an instruction receiving server (not shown in the figure) of the subnet through a unidirectional transmission line 30' (such as a simplex serial port line), and then the instruction receiving server of the subnet transmits the control instruction to the computer to be controlled through a network path such as a switch and/or a router in the subnet; the network path herein mainly refers to a network path within a subnet, and if the transmission is performed through a network path outside an additional subnet, the network path may cause an additional network exposure in the interactive process; the use of switches or routers is related to the complexity of the network of the sub-network itself, and is well known to those skilled in the art and therefore omitted. And the computer to be controlled in the subnet receives the control instruction and responds to the control instruction, and finally, the response result is output. The response result may also be further output or output to a display unit corresponding to the control instruction generating device 5 through a non-network transmission device, for example, the video data line 20 '(or 20 ", 20"'), as required.
After the instruction receiving server sends the control instruction to the computer to be controlled through a network, the computer to be controlled responds to the control instruction, and the responding may include: open a file, close a file, etc. Subsequently, the opened folder interface in the computer to be controlled is directly output through a video data line connected to the computer, or output to a display unit corresponding to the control instruction generating apparatus 5.
Further details of the various parts of the foregoing solution will be described in more detail below.
The control instruction generating device 5 in fig. 1 is used for generating control instructions, and the control instructions are sent to the interaction server through a control instruction transmission line 30. The control instruction generating device may be, for example, an infrared frame touch input and display control instruction generating device, or a capacitive touch and display control instruction generating device. The control instruction generating device may be a combination of a control instruction generating device and a display device for capturing a touch or other control action by various methods such as electric induction, magnetic induction, thermal induction, and optical induction, or may be another device capable of generating a control instruction, such as a mouse and a keyboard.
In addition, the control instructions may also be generated via a network approach.
In some embodiments, the means for interacting with computers within a subnet further comprises a non-network transmission device for transmitting the control instruction to the interaction server (if the network transmission device or the network, the control instruction may be leaked or the content of the interaction computer may be leaked).
The interactive server determines the corresponding computer to be controlled and the ID thereof according to the control instruction, for example, the interactive server determines the computer to be controlled by the control instruction according to the information carried by the control instruction and related to the computer to be controlled, for example, determines the computer to be controlled according to some fields in the control instruction.
In addition, the interactive server may also store a correspondence relationship between the control command and the computer to be controlled in advance, determine the computer to be controlled by the control command according to the correspondence relationship, and then transmit the control command to the command receiving server of the subnet in which the computer to be controlled is located.
The above realizes the unidirectional transmission of the control command through the unidirectional transmission line, which can also be replaced by all unidirectional transmission devices. The unidirectional transmission device or the unidirectional transmission line in the figure may include a simplex serial port line, or include a duplex serial port line, wherein a return line in the duplex serial port line is broken, and a reserved line is used for unidirectional transmission of the control command to the interaction server.
FIG. 2 shows a schematic block diagram of a portion of an apparatus for interacting with computers within a subnet in accordance with another embodiment of the present invention.
The main difference between fig. 2 and fig. 1 is that in fig. 2, a splice controller 4 'and a splice screen 5' are introduced, and the response result is displayed on the splice screen. The stitching controller 4 ' is connected to the video data lines 20 ', 20 "and 20 '" and to the interaction server 4. Each video data line 20 ', 20 "' is connected to one computer in the subnet (3 computers in the subnet), and the splice controller connects the plurality of video data lines 20 ', 20"' and the interaction server. Since the interactive server can determine the computer to be controlled by the control command (as described above), the interactive server can control the splicing controller accordingly, so that the response result of the computer to be controlled by the control command can be displayed on the splicing screen in a layout manner through the second video data line and the splicing controller connected to the computer; the layout mode comprises displaying the related content in a full screen or a half screen mode, or displaying the related content in a certain size at a certain position on the screen.
As can be seen from the foregoing description of the embodiments of the present invention, the present invention can implement secure interaction on computers in a subnet under an original network environment of the subnet, where the introduction of the interaction does not make the computers in the subnet increase the risk of network exposure.
