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.
In the present application, the use of the connection lines such as the optical fiber and the serial port is related to, in order to match these connection lines, a conversion module may need to be used in a supporting manner, for example, when a signal is converted from a network to the optical fiber, a network light conversion module is needed, but in the case that the computer network port itself is an optical port, an additional network light conversion module may be omitted, since whether such a module is necessary or not may be determined according to an actual application scenario and is well known to those skilled in the art, for the sake of simplicity, the description is not given one by one, but the omission of the necessary conversion module is not indicated. 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 illustrates a schematic block diagram of a multi-signal source interface interaction system according to some embodiments of the inventions.
The connection line types corresponding to the figures are as follows: 1. a network cable; usb line; 3. a bi-directional serial port line; 4, a one-way serial port line; 5. a unidirectional optical fiber; 6. and (5) video lines.
The illustrated multi-signal-source interface interaction system includes an interaction service and instruction acquisition device 9, a switch 10, a security instruction service box 11, a security interface isolation box 15, an image processing and display device 16, and an instruction unidirectional isolation box 11'. According to some embodiments of the present invention, the apparatus may further include one or more of the command output box 12, the tiled screen 17, the display device 8', the control command generating device 8, and the wiring between the components. The display screen 17 may also be a non-tiled screen.
The control instruction generating device 8 may be, for example, an infrared frame touch input device, and may also be a capacitive touch device. The control instruction generating device may capture touch or other control actions by various methods such as electric induction, magnetic induction, thermal induction, and optical induction, or may generate other control instructions, such as a mouse and a keyboard. In addition, the control instructions may also be generated via a network approach. The control command generating device 8 can generate a gesture command, a keyboard, mouse control command, or a touch command. According to some embodiments of the present invention, the control instruction generating apparatus may be spatially superimposed on the display apparatus 8', and as will be further described below, the display apparatus 8' may provide a screen of a control object, and when the control instruction generating apparatus is a transparent touch device, by superimposing the touch device on the display apparatus, visual touch may be implemented on the control instruction generating apparatus by referring to the screen of the display apparatus 8' below the transparent touch device. The display device 8' and the control instruction generating device 8 are connected in the overall apparatus as shown in fig. 1.
The control instruction generating device can also be an infrared light curtain type touch screen based on the display device 8 'or the spliced screen 17, wherein an infrared light curtain is arranged on the surface of the display device 8' or the spliced screen 17. The infrared light curtain may be formed on the screen surface by an infrared laser or a laser array above the screen, and when the user acts on the display device 8' in which the infrared light curtain is arranged or the tiled screen 17 by a finger or the like, the touch input of the user in the screen is captured by the infrared camera. For example, when a touch is performed on the display device 8' or the tiled screen 17, the light distribution of the infrared light curtain at the touch point X will change due to the touch behavior, e.g., part of the infrared light at the touch point is diffusely reflected by the touch finger off the display device 8' or the tiled screen 17 and is captured by the infrared camera located in front of the display device 8' or the tiled screen 17; or part of the infrared light at the touch point is transmitted through the screen due to the action of the touch finger (for example, when the screen is a transflective DLP screen), and then is shot by the infrared camera positioned behind the screen. Touch control can be recognized by recognizing the position of the infrared contact in the shooting result.
The image processing and display device 16 is used for processing and outputting the input video signals, for example, after the signals are spliced with each other, or after the input signals are partially cut, the signals are displayed on a spliced screen in a certain layout. The layout comprises the window distribution size and position of each signal source on the screen. The image processing and display device 16 may be, for example, a stitching controller. The mosaic controller may also output the content output onto the mosaic screen to the display device 8' such that the content displayed thereon is the same as the content on the mosaic screen.
The interactive service and instruction acquisition device is used for receiving the control instruction from the control instruction generation device, reading real-time layout information on a screen from the image processing and display device, such as the splicing controller, judging a signal source to be operated by touch according to the layout information and the touch position indicated in the control instruction, determining an output port (or a transmission link) of a safety instruction service box corresponding to the signal source by reading the configuration file, and sending the determination results to the safety instruction service box. For example, the interactive service and instruction acquisition device reads a real-time layout from the splicing controller, determines distribution positions of each signal source on the screen, and can determine that a position to which touch is applied corresponds to the signal source 14 by analyzing touch information in the control instruction, and then the interactive service and instruction acquisition device sends the related control instruction to a safety instruction service box corresponding to the signal source 14, and the safety instruction service box further sends the control instruction to the signal source, so that the interactive service and instruction acquisition device responds to the control instruction. The signal source may convert the touch coordinates in the control command into coordinates of a signal source program space in response to the control command, for example, by converting the touch coordinates (touch coordinates on the control command generating device) into screen coordinates and converting the screen coordinates into coordinates of the signal source program space), and thereby correspondingly convert the control command into an operation in the signal source program space.
According to some embodiments of the present invention, the interactive service and instruction collection device may further determine whether the control instruction corresponds to a global operation instruction; and if the control command corresponds to the global operation command, the control command is not forwarded to a signal source or a safety command service box. The global operation instruction refers to an operation instruction which is not used for controlling each specific signal source, and the global operation instruction may include, for example, an instruction for controlling an image processing and display apparatus to change a layout of each signal source on a screen, the changing including: displaying the content of other signal sources on the screen (or called switching window) to which the current touch is applied; or, the content on the screen acted by the current touch is displayed on the whole combined spliced screen in a full screen mode (or called full screen display); or changing the size of a display window on the screen acted by the current touch; or changing the size of a display window of the display content of each signal source on the screen; or changing the position of the display window of the display content of each signal source on the screen; or pushing the content on the screen used by the current touch to other screens or screens; or switching various pre-stored layout manners, for example, a plurality of layout manners may be pre-stored, in each layout manner, the same or different signal sources (1 or more) are displayed on the screen according to a certain manner or layout, and when the touch action of the user corresponds to switching various pre-stored layout manners, the layout of the whole screen is switched every touch operation. According to some embodiments, some touches may be set to correspond to global operation instructions and other touches may be set to correspond to non-global operation instructions according to operation habits. For touches corresponding to non-global operational instructions, the corresponding touch information is sent to the corresponding signal source as described above. The touches corresponding to the global operation instruction may include, for example, O, M, C, touch gestures such as < >, or one or more fingers or a pointer sliding on the screen in some other manner, or directional touch actions (e.g., left, right, front left, front right, etc. touches corresponding to pushing a picture displayed on the screen in front of the eye to the screen on the left, the screen on the right, the screen in front of the left, the screen in front of the right, etc., respectively). The touch corresponding to the non-global operation instruction may include, for example, a double-click, a single-click, or the like touch action on the screen. According to some embodiments, some touch actions may also be introduced as boundaries for global or non-global operation instructions. For example, after one W is applied, all touches will correspond to global operation commands, and after one M is applied, all touches will correspond to non-global operation commands. For example, the interactive service and instruction acquisition device may receive the touch input gesture W, control the stitching controller to enter a screen layout adjustment mode (or called a display layout adjustment mode), and then control the stitching controller according to the movement direction and the movement distance of the gesture, so that the stitching controller responds to the instruction corresponding to the gesture to change the predetermined signal source layout mode or the size and/or position of the signal source display window. According to some embodiments, some touch actions may also be introduced as global operation instructions, and the global operation instructions are corresponding to boundaries of the global operation instructions and the non-global operation instructions. For example, after one W is applied, all touches will correspond to global operation commands, and after one M is applied, all touches will correspond to non-global operation commands. For example, the interactive service and instruction acquisition device may receive the touch input gesture W, control the stitching controller to enter a screen layout adjustment mode (or called a display layout adjustment mode), and then control the stitching controller according to the movement direction and the movement distance of the gesture, so that the stitching controller responds to the instruction corresponding to the gesture to change the predetermined signal source layout mode or the size and/or position of the signal source display window.
According to other embodiments of the present invention, the interactive service and instruction collecting device determines the signal source to be controlled by the control instruction and the output port of the corresponding safety instruction service box according to the information carried by the control instruction and related to the signal source to be controlled, for example, determines the signal source to be controlled and the output port of the corresponding safety instruction service box according to some fields in the control instruction. In addition, the interactive service and instruction acquisition equipment can also pre-store the corresponding relation between the control instruction and the signal source to be controlled, judge the signal source to be controlled by the control instruction and the output port of the corresponding safety instruction service box according to the corresponding relation, and then send the control instruction and the output port information of the corresponding safety instruction service box to the safety instruction service box; when signal sources of different networks need to be called, the interactive service and instruction acquisition equipment can send the control instruction and the output port information of the corresponding safety instruction service box to the safety instruction service box of the subnet where the signal source to be controlled is located. According to other embodiments of the present invention, the signal source to be controlled by the control command and the output port of the corresponding safety command service box (as described below) may also be determined by the safety command service box itself.
The safety instruction service box 11 comprises an instruction distribution server 21, a serial port optical transceiver transmitting end 22, a serial port optical transceiver receiving end 24, optical fibers connecting the serial port optical transceiver receiving end and the transmitting end, an optical fiber isolator 23 in the optical fibers, and a one-way serial port line connecting the transmitting end. In the present application, the optical fiber and the fiber isolator are collectively referred to as a unidirectional optical fiber for simplicity of description. The transmitting end and the receiving end of the serial optical transceiver can also be called serial optical equipment or optical serial equipment. The instruction distribution server 21 is configured to convert the control instruction in the form of the network signal into a control instruction in the form of a serial port, and output the control instruction along a corresponding serial port optical transceiver transmitting end, a corresponding unidirectional optical fiber, and a corresponding serial port optical transceiver receiving end, such as along the transmission link in line 1 of fig. 2 or along the transmission link in line 2. Two sets of transmission links are shown in the figure, and the transmission links of the corresponding sets can be configured according to the number of actual signal sources. Under the condition that the network end connection line is an optical fiber, the safety instruction service box 11 may include an instruction distribution server 21 and a plurality of unidirectional optical fibers, where the instruction distribution server 21 is configured to distribute the control instruction to the corresponding unidirectional optical fibers, so that the control instruction is transmitted to the signal source to be controlled in a unidirectional manner through the corresponding unidirectional optical fibers, that is, at this time, it is not necessary to convert the network signal into an optical signal separately. According to some embodiments of the present invention, in a case that the network end is connected by a cable, the instruction distribution server is configured to convert the control instruction in the form of the network signal into the control instruction in the form of the optical signal, and distribute the control instruction in the form of the optical signal to the corresponding unidirectional optical fiber, so that the control instruction is transmitted to the signal source to be controlled in a unidirectional manner through the corresponding unidirectional optical fiber.
According to some embodiments of the present invention, after the safety instruction service box 11 obtains the control instruction, the instruction distribution server determines the signal source to be controlled by the control instruction, and may determine which output port of the safety instruction service box the control instruction is to be sent to by reading the configuration file. The configuration file defines the correspondence of each signal source (ID) to an output port (or transmission link). According to some embodiments of the invention, the functionality of the instruction distribution server may also be integrated into the interaction service and instruction collection device 9.
The safety interface isolation box 15 includes a video optical transceiver transmitting end 31, a video optical transceiver receiving end 32, optical fibers connecting the video optical transceiver receiving end and the video optical transceiver transmitting end, an optical fiber isolator 33 in the optical fibers, and a video cable connecting the video optical transceiver transmitting end, and is used for implementing unidirectional transmission in the x direction shown in the figure, as shown in fig. 3. The transmitting end and the receiving end of the video optical transceiver may also be called an electrical-to-optical device or an optical-to-electrical device, or a visual-to-optical device or an optical-to-visual device according to the difference of the converted objects. Two sets of transmission links are shown in the figure, and the transmission links of the corresponding sets can be configured according to the number of actual signal sources. Each transmission link comprises a video optical transceiver transmitting end, a video optical transceiver receiving end, optical fibers connecting the video optical transceiver receiving end and the video optical transceiver transmitting end, and an optical fiber isolator in the optical fibers.
The instruction unidirectional isolation box 11' comprises a unidirectional serial port line connected with a signal source, a serial light conversion device 18, a unidirectional optical fiber, a light conversion serial device 19 and a unidirectional serial port line connected with an image processing and display device. The instruction unidirectional isolation box is used for receiving the control instruction generated on the signal source and enabling the control instruction to be transmitted to the image processing and display equipment in a unidirectional mode.
The following further describes a security interface interaction process or method of the multi-signal source interface interaction system.
As shown in fig. 1, the control instruction generating device 8 transmits a control instruction to the interactive service and instruction collecting device 9 through a usb cable (or other transmission device).
The interactive service and instruction acquisition device 9 receives the control instruction and judges the control object of the control instruction: when the control instruction is directed to the image processing and display device, the interactive service and instruction acquisition device 9 may directly control the illustrated image processing and display device 16 according to the control instruction, for example, to make the image processing and display device control the layout manner of the output image on the mosaic screen according to the control instruction. When the control command is directed to a signal source, the interactive service and command acquisition device 9 sends the control command to the safety command service box 11 through a network (such as a switch 10 in the figure).
The instruction distribution server 21 in the safety instruction service box 11 receives the control instruction, converts the control instruction in the form of network signal into a control instruction in the form of serial port signal, and transmits the control instruction to the serial port optical transceiver transmitting terminal 22, the unidirectional optical fiber, and the serial port optical transceiver receiving terminal 24, and directly transmits the control instruction to the signal source (13, 14) to be controlled through the unidirectional serial port line 4 (without involving the instruction output box 12 shown by the dotted line in the figure), so that the signal source responds and outputs the response result through the video line.
The safety interface isolation box 15 receives the video response result, and outputs the video response result to the image processing and display device 16 in a unidirectional manner through the video optical transmitter and receiver, the unidirectional optical fiber, the video optical transmitter and receiver, and the video cable.
The image processing and display device 16 receives the video response result and outputs it to the tiled screen 17 and/or the display device 8'.
The image processing and display device 16 also monitors control instructions from a signal source (e.g., signal source 14): when a user operates directly on the signal source to input control instructions related to controlling the layout of the signal source or other signal sources on the tiled screen, the control instructions will be transmitted unidirectionally to the image processing and display device 16 by instructing the unidirectional isolation box (i.e., unidirectional serial port line, serial-to-optical device 18, unidirectional optical fiber, optical serial-to-serial device 19, and unidirectional serial port line), and the layout of the signal source or other signal sources on the tiled screen is controlled by the image processing and display device 16.
