[0025] First embodiment

[0026] Figure 1 This is a functional block diagram of a multi-computer switching device provided in the first embodiment of the present application. Figure 1As shown, the first embodiment of the present application provides a multi-computer switching device 1 which automatically adapts to an external auxiliary keyboard KP. The multi-computer switching device 1 includes a processing circuit 10 , a connection module 12 and a signal distribution circuit 14 .

[0027] The connection module 12 is electrically connected to the processing circuit 10 and the external auxiliary keyboard KP. In the present embodiment, the connection module 12 may include a wireless connection module 120 for communicating with the external auxiliary keyboard KP having wireless connection capability. The wireless connection module 120 may be, for example, a wireless communication device applicable to various wireless communication standards, such as short-range wireless communication, Bluetooth, 2.4 GHz wireless connection, ZigBee, ultra-wideband, etc. The wireless connection module 120 may include one or more antennas, antenna control circuits, and signal processing circuits.

[0028] The signal distribution circuit 14 is electrically connected to the processing circuit 10, wherein the signal distribution circuit 14 has host ports Pc1, Pc2, Pc3, and Pc4 and a first display port Pd1. The signal distribution circuit 14 can be electrically connected to computer hosts CH1, CH2, CH3, and CH4 through the host ports Pc1, Pc2, Pc3, and Pc4, respectively, to receive image signals Sdp1, Sdp2, Sdp3, and Sdp4 from the computer hosts CH1, CH2, CH3, and CH4, respectively. In addition, the signal distribution circuit 14 is also connected to the first display device DP1 through the first display port Pd1.

[0029] The processing circuit 10 and the signal distribution circuit 14 may each include one or any combination of an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or a system on a chip (SOC), but the present application is not limited thereto. The processing circuit 10 may also be connected to the storage circuit 11 for storing information related to the input command, for example, a comparison table may be stored, which defines the correspondence between multiple input commands and multiple signal configuration modes, and the processing circuit 10 may generate a screen setting signal accordingly.

[0030] In addition, the signal distribution circuit 14 may also include one or more switching circuits, each of which may be, for example, a bipolar junction transistor (BJT), a transistor multiplexer, a metal-oxide-semiconductor field-effect transistor (MOSFET), a multiplexer or a demultiplexer, etc., which can control the signal transmission path according to the switching signal.

[0031] In this embodiment, the processing circuit 10 can be configured to receive an input command Sin from an external auxiliary keyboard KP through a connection module 12, and generate a screen setting signal Ssc according to the input command Sin to control the signal distribution circuit 14 to distribute image signals Sdp1, Sdp2, Sdp3 and Sdp4 according to the signal configuration mode, and control the first display device DP1 to perform screen display according to the signal configuration mode.

[0032] For example, the external auxiliary keyboard KP may include at least a plurality of numeric keys, but the present application is not limited thereto. A common external auxiliary keyboard KP may include, for example, ten numeric keys from 0 to 9, four arithmetic keys such as "+", "-", "*", and " / ", a symbol key ".", an input key "Enter", and a numeric lock key "Num" (abbreviation of Numlock).

[0033] Figure 2 This is a schematic diagram of a multi-computer switching device in one operation scenario according to the first embodiment of the present application. Figure 2 In the operation scenario, there are four computer hosts CH1, CH2, CH3 and CH4 and a first display device DP1. The host ports Pc1, Pc2, Pc3 and Pc4 can be arranged in sequence with multiple numbers (for example, 1 to 4). When the user presses one of the keys 1 to 4, the input command is one of the numbers 1 to 4, and the processing circuit 10 can generate a screen setting signal Ssc according to the input command (for example, 1), and its signal configuration mode is to display the image signal of the host port Pc1 through the first display device DP1. Therefore, the screen setting signal Ssc generated according to the input command (for example, 1) can be used to control the first display device to display the image signal Sdp1 of the host port Pc1 corresponding to the number "1" input by DP1. However, the above example is only one feasible embodiment and is not used to limit the present application.

[0034] In addition, when the input command is a combination of two numeric keys with an arithmetic operation key between them, the screen setting signal Ssc generated by the processing circuit 10 can be used to control the number and display mode of the image signals displayed on the first display device DP1.

[0035] Figure 3 This is a schematic diagram of the multi-computer switching device of the first embodiment of the present application in another operation scenario. Figure 2In an operation scenario, there are four computer hosts CH1, CH2, CH3 and CH4 and a first display device DP1. The host ports Pc1, Pc2, Pc3 and Pc4 can be arranged in sequence with multiple numbers (for example, 1 to 4). When the user presses two number keys from 1 to 4 and inputs a key combination of an arithmetic operation key "+" between the two number keys, for example, the input command is "1+2", then the processing circuit 10 can generate a screen setting signal Ssc according to the input command "1+2", and its signal configuration mode is to display the image signals of the host ports Pc1 and Pc2 through the first display device DP1. Therefore, the screen setting signal Ssc generated according to the input command (for example, "1+2") can be used to control the first display device to display the image signals Sdp1 and Sdp2 of the host ports Pc1 and Pc2 corresponding to the numbers "1" and "2" input by DP1. In addition, the above two image signals Sdp1 and Sdp2 can be displayed in an average split screen mode or a picture-in-picture mode by default. However, the above example is only one feasible embodiment and is not intended to limit the present application. It is conceivable that an arithmetic operation key "+" and a numeric key "1" or "2" can be added to set the display mode of the two image signals Sdp1 to be an average split screen mode or a picture-in-picture mode. In addition, a rule of pressing the "Enter" key can also be added to determine whether the user's command has been entered.

[0036] As can be seen from the above, the multi-computer switching device provided by the present application can realize more diverse configuration functions through simple combination key logic, in addition to being able to configure signals through the simplest single-key command through the numeric keypad, through the connection and operation method designed specifically for the auxiliary keyboard.

[0037] Second embodiment

[0038] Figure 4 This is a functional block diagram of a multi-computer switching device provided in the second embodiment of the present application. Figure 4 In the embodiment, the same components as those in the first embodiment are marked with similar component symbols, and repeated descriptions are omitted. Figure 4 As shown, the second embodiment of the present application provides a multi-computer switching device 2 that automatically adapts to an external auxiliary keyboard KP. The multi-computer switching device 2 includes a processing circuit 20, a connection module 22, a signal distribution circuit 24 and a keyboard and mouse connection module 26.

[0039] In the present embodiment, the connection module 22 can be electrically connected to the external auxiliary keyboard KP through the dedicated port 220. For example, the dedicated port 220 can be electrically connected to the external auxiliary keyboard KP through a transmission line, or wirelessly connected to the external auxiliary keyboard KP through a wireless adapter. The wireless adapter can be similar to the wireless connection module 120 of the first embodiment, and can be, for example, a wireless communication device applicable to various wireless communication standards, such as short-range wireless communication, Bluetooth, 2.4 GHz wireless connection, ZigBee, ultra-wideband, etc. The dedicated port 220 can be, for example, a USB port, and the connection module 22 can include a USB driver circuit.

[0040] In addition, the keyboard / mouse connection module 26 can be used to connect to the keyboard / mouse KM by wire or wirelessly, and the signal distribution circuit 24 can receive a keyboard / mouse signal group Skm from the keyboard / mouse KM through the keyboard / mouse connection module 26 .

[0041] In this embodiment, the signal distribution circuit 24 has host ports Pc1, Pc2, Pc3 and Pc4, a first display port Pd1 and a second display port Pd2. The signal distribution circuit 14 can be electrically connected to computer hosts CH1, CH2, CH3 and CH4 through the host ports Pc1, Pc2, Pc3 and Pc4, respectively, to receive image signals Sdp1, Sdp2, Sdp3 and Sdp4 from the computer hosts CH1, CH2, CH3 and CH4, respectively. In addition, the signal distribution circuit 14 is also connected to the first display device DP1 and the second display device DP2 through the first display port Pd1 and the second display port Pd2, respectively.

[0042] In this embodiment, the processing circuit 20 can be configured to receive an input command Sin from an external auxiliary keyboard KP through a connection module 22, and generate a screen setting signal Ssc according to the input command Sin to control the signal distribution circuit 14 to distribute image signals Sdp1, Sdp2, Sdp3 and Sdp4 according to the signal configuration mode, and control the first display device DP1 and the second display device DP2 to perform screen display according to the signal configuration mode.

[0043] In addition, the processing circuit 20 is further configured to generate a mouse-key distribution signal Sakm according to the input command Sin to control the signal distribution circuit 24 to distribute the mouse-key signal set Skm to the corresponding computer host CH1, CH2, CH3 or CH4 according to the mouse-key distribution mode.

[0044] Figure 5 This is a schematic diagram of a multi-computer switching device in one operation scenario according to the second embodiment of the present application. Figure 5In the operation scenario, there are four computer hosts CH1, CH2, CH3 and CH4 and two display devices, namely the first display device DP1 and the second display device DP2. The host ports Pc1, Pc2, Pc3 and Pc4 can be numbered in sequence (for example, 1 to 4), and the first display port Pd1 and the second display port Pd2 can be numbered in sequence (for example, 1 to 2). The user can use more than two numeric keys in combination with at least one arithmetic operation key "*" for control.

[0045] For example, when the user presses a number key among 1 and 2, plus an arithmetic operation key "*", and then a number key combination among 1 to 4, for example, the input command is "1*2", then the processing circuit 10 can generate a screen setting signal Ssc according to the input command "1*2", and its signal configuration mode is to display the image signal of the host port Pc2 through the first display device DP1. Therefore, the screen setting signal Ssc generated according to the input command (for example, "1*2") can control the first display device DP1 to display the image signal Sdp2 of the host port Pc2 corresponding to the input rear number "2" according to the front number "1". In addition, after entering "1*2", the "Enter" key can be added to indicate that the input has been completed.

[0046] After the "Enter" key, the user can control by inputting another input instruction. For example, the user can press the number key "2", plus an arithmetic operation key "*", and then a key combination of a number key from 1 to 4. For example, the input instruction is "1*3", then the processing circuit 10 can generate another screen setting signal Ssc according to the input instruction "2*3", and its signal configuration mode is to display the image signal of the host port Pc3 through the second display device DP2. Therefore, the screen setting signal Ssc generated according to the input instruction (such as "2*3") can control the second display device DP2 to display the image signal Sdp3 of the host port Pc3 corresponding to the input rear number "3" according to the front number "2".

[0047] Figure 6 This is a schematic diagram of the multi-computer switching device of the second embodiment of the present application in another operation scenario. Figure 6 In the operation scenario, there are four computer hosts CH1, CH2, CH3 and CH4 and two display devices, namely the first display device DP1 and the second display device DP2. The host ports Pc1, Pc2, Pc3 and Pc4 can be numbered in sequence (for example, 1 to 4), and the first display port Pd1 and the second display port Pd2 can be numbered in sequence (for example, 1 to 2). The user can use more than three numeric keys in combination with at least one arithmetic operation key "*" and at least one arithmetic operation key "+" for control.

[0048] For example, when the user presses a number key among 1 and 2, plus an arithmetic operation key "*", plus a key combination of an arithmetic operation key "+" sandwiched between two number keys among 1 to 4, for example, the input instruction is "1*1+2", then the processing circuit 10 can generate a screen setting signal Ssc according to the input instruction "1*1+2", and its signal configuration mode is to display the image signals of the host ports Pc1 and Pc2 through the first display device DP1. Therefore, the screen setting signal Ssc generated according to the input instruction (for example, "1*1+2") can control the first display device DP1 to display the image signals Sdp1 and Sdp2 of the host ports Pc1 and Pc2 corresponding to the input middle and rear numbers "1" and "2" according to the front number "1". In addition, after entering "1*1+2", the "Enter" key can be added to indicate that the input has been completed.

[0049] After pressing the "Enter" key, the user can control by inputting another input instruction. For example, the user can press the number key "2", plus an arithmetic operation key "*", and then a key combination of two number keys from 1 to 4 with an arithmetic operation key "+" sandwiched between them. For example, the input instruction is "2*3+4", and the processing circuit 10 can generate another screen setting signal Ssc according to the input instruction "2*3+4", and its signal configuration mode is to display the image signals of the host ports Pc3 and Pc4 through the second display device DP2. Therefore, the screen setting signal Ssc generated according to the input instruction (for example, "2*3+4") can control the second display device DP2 to display the image signals Sdp3 and Sdp4 of the host ports Pc3 and Pc4 corresponding to the input middle and rear numbers "3" and "4" according to the front number "2".

[0050] Furthermore, the image signals Sdp1 and Sdp2 may be displayed on the first display device DP1 in an evenly split screen mode or a picture-in-picture mode by default, and the image signals Sdp3 and Sdp4 may be displayed on the second display device DP2. However, the above example is only one feasible embodiment and is not intended to limit the present application. It is conceivable that an arithmetic operation key "+" and a number key "1" or "2" may be added to set the display mode to be used by the first display device DP1 or the second display device DP2 to be an evenly split screen mode or a picture-in-picture mode. However, the present application is not limited to the above examples, and the source, quantity and display mode of the image signals finally displayed by the first display device DP1 and the second display device DP2 may be determined by superimposing input instructions.

[0051] In addition, Figure 5 and Figure 6In the two scenarios, the mouse and key assignment mode can also be determined by the "Num" command. For example, when the user continuously presses the "Num", "1", "Enter" and other keys, the processing circuit 20 can generate a mouse and key assignment signal Sakm to control the signal assignment circuit 24 to assign the mouse and key signal group Skm to the computer host CH1 corresponding to the middle number "1".

[0052] However, the present application is not limited to the above examples. For example, a specific key combination may be used to allow the user to customize the key combination and the corresponding function.
