Description

Switching system and switching method

Technical Field

The present invention relates to a switching system, in particular to a switching system comprising a plurality of switching devices.

Background technique

Through a KVM switch, a set of keyboard, monitor and mouse can be used to control multiple hosts. However, due to the limited number of ports on a single KVM switch, it may not be able to meet the user's needs to control a large number of hosts. If you want to provide consumers with a KVM switch with more ports, you must design the KVM switch according to the required specifications. The greater the change in specifications, the more complex the design will be. In addition, the production cost of a KVM switch with more ports is also correspondingly higher, so the product has to be priced higher, affecting consumers' willingness to buy. Furthermore, when you want to control and set the KVM switch, you must connect the keyboard and mouse to the KVM you want to control before you can set it. Therefore, when there are multiple KVM switches connected to each other, if you need to set the KVM switches separately, you must connect the keyboard and mouse to each KVM switch separately before you can control and set it, which is inconvenient. Therefore, how to increase the number of controllable hosts without significantly changing the specifications of the KVM switch is a problem that urgently needs a solution in this field.

The following is an explanation of the implementation of the present invention with reference to the accompanying drawings and some embodiments of the present invention. However, the technical details described below and the contents of the accompanying drawings are only exemplary, and the scope of the present invention is not limited thereto.

Although the terms first, second, etc. are used herein to describe various elements, components, and regions, these elements, components, and regions should not be limited by these terms. These terms are only used to distinguish one element, component, or region from another element, component, or region.

Fig. 1 is a schematic diagram of a switching system 100 according to an embodiment of the present invention. Referring to Fig. 1, in one embodiment, the switching system 100 may include a first switch 110, a second switch 120, a first host 111, and second hosts 121-122.

As shown in FIG. 1 , in this embodiment, the first switch 110 is connected to the first host 111, and receives the first screen data 111a from the first host 111. The first switch 110 generates the first integrated screen data (not shown) according to the first screen data 111a received from the first host 111. The first switch 110 may have a processing element such as a central processing unit, a microprocessor, a logic operation unit or a programmable chip, and generates the first integrated screen data according to the first screen data 111a through the processing element. It should be noted that in other embodiments, the first switch 111 may be connected to other numbers of first hosts, and the present invention is not limited to the number of first hosts connected to the first switch 110.

As shown in FIG. 1 , in this embodiment, the switching system 100 further includes a second switch 120. The second switch 120 is connected to a second host 121 and a second host 122. The second switch 120 receives second screen data 121a from the second host 121, and receives second screen data 122a from the second host 122. Here, similar to the first switch 110, the second switch 120 can generate second integrated screen data 120a according to the second screen data 121a and the second screen data 122a through the processing element included therein. In other embodiments, the second switch 120 can be connected to other numbers of second hosts, and the present invention is not limited thereto.

As shown in FIG. 1 , the first switch 110 receives the second integrated screen data 120a from the second switch 120, and generates display data 100a based on the first integrated screen data and the second integrated screen data 120a; however, the present invention is not limited thereto, and in other embodiments, the first switch 110 may not generate the display data 100a, as described in detail in another embodiment below.

In this embodiment, the first switch 110 outputs the display data 100a to the display 20, so that the display 20 displays a picture according to the content of the display data 100a. In addition, the first switch 110 acts as a master switch (master) to receive the control signal 30, and the second switch 120 acts as a slave switch (slave) controlled by the first switch 110.

In another embodiment, the display 20 is connected to the second switch 120 (not shown), the second switch 120 receives the first screen data 111 (or the first integrated screen data) from the first switch device 110, and the second switch 120 generates display data 100a according to the first screen data 111 (or the first integrated screen data) and the second integrated screen data 120a, and then transmits it to the display 20 for display. In this embodiment, the second switch 120 acts as a master switch to receive the control signal 30, and the first switch 110 acts as a slave switch to be controlled by the second switch 120. In other words, the first switch 110 or the second switch 120 can be set as the master switch according to the user's needs, and the other switches can be set as slave switches, so as to better meet the needs of on-site use.

2A and 2B , operation examples of controlling each host in the switching system 100 under different usage scenarios will be described below.

FIG. 2A is a schematic diagram of an operation example of the present invention. Referring to FIG. 1 and FIG. 2A , in this operation example, the display 20 displays a screen C100 as shown in FIG. 2A based on the display data 100a. In this operation example, the display data 100a includes a first range R110, a second range R120, a first host range R111, a second host range R121, and a second host range R122. In addition, the display data 100a also includes a first depth value (not shown) and a second depth value (not shown). In this operation example, the first range R110 and the first depth value correspond to the first integrated screen data; the second range R120 and the second depth value correspond to the second integrated screen data 120a; the first host range R111 corresponds to the first screen data 111a; the second host range R121 corresponds to the second screen data 121a; the second host range R122 corresponds to the second screen data 122a.

As shown in FIG. 2A , the first range R110 partially covers the second range R120, wherein the outline of the covered portion of the second range R120 is drawn with a dotted line, and the covered portion forms an overlapping area. In this operation example, if the first depth value of the first switch 110 is set to be less than the second depth value, the first range R110 in the overlapping area covers the second range R120. In another embodiment, if the first depth value of the first switch 110 is set to be greater than the second depth value, the first range R110 in the overlapping area covers the second range R120. The following description assumes that the first depth value is less than the second depth value, and the first range R110 covers the second range R120 in the overlapping area to describe this operation example.

In this operation example, the control signal 30 includes a position information. For example, the position information of the control signal 30 may be the position L1 or the position L2 shown in FIG. 2A (L1 and L2 may be specific coordinates). The first switch 110 may determine which device is controlled by the control signal 30 based on the position information of the control signal 30. For example, if the position information of the control signal 30 falls within the first range R110, the first switch 110 may determine that the control signal 30 controls the first switch 110; if the position information of the control signal 30 falls within the first range R110 and falls within the first host range R111, the first switch 110 may serve as the main switch and determine that the control signal 30 controls the first switch 110 based on the position information of the control signal 30 falling within the first range R110. Then, the first switch 110 controlled by the control signal 30 as determined by the main switch may be controlled based on the control signal 30. If the position information of the control signal 30 falls within the first host range R111, the control signal 30 is determined to control the first host 111, and the control signal is transmitted to the first host 111 (as shown by arrow 31 in FIG. 1 ); if the position information of the control signal 30 falls within the second range R120, the first switch 110 can determine that the control signal 30 controls the second switch 120, and transmit the control signal to the second switch 120 (as shown by arrow 32 in FIG. 1 ); if the position information of the control signal 30 falls within the second range R120 and falls within the second host range R120, the first switch 110 can determine that the control signal 30 controls the second switch 120, and transmit the control signal to the second switch 120 (as shown by arrow 32 in FIG. 1 ); 1, the first switch 110 can be used as the main switch and determine that the control signal 30 controls the second switch 120 according to the position information of the control signal 30 falling into the second range R120. Then, the second switch 120 controlled by the control signal 30 determined by the main switch can determine that the control signal 30 controls the second host 121 according to the position information of the control signal 30 falling into the second host range R122, and transmit the control signal to the second host 121 (as shown by arrows 32 and 33 in FIG. 1); if the position information of the control signal 30 falls into the second range R120 and falls into the second host range R122, the first switch 110 can act as the main switch and determine that the control signal 30 controls the second switch 120 based on the position information of the control signal 30 falling into the second range R120. Then, the second switch 120 controlled by the control signal 30 determined by the main switch can determine that the control signal 30 controls the second host 122 based on the position information of the control signal 30 falling into the second host range R122, and transmit the control signal to the second host 122 (as shown by arrows 32 and 34 in Figure 1).

As shown in FIG. 2A , the position L1 and the position L2 fall within the overlapping area of the first range R110 and the second range R120, and the position L2 also falls within the overlapping area of the first host range R111 and the second host range R121. The position L1 and the position L2 may be, for example, specific coordinate values, and the coordinate system in the screen C100 will be described in detail later with reference to FIG. 3 . In this operation example, when the position information of the control signal 30 falls within the position L1, it falls within the first range R110 and the second range R120 at the same time. At this time, the first switching device 110 may determine that the control signal 30 controls the first switch 110 based on the first depth value being less than the second depth value. For example, in a usage scenario, the position information of the control signal 30 falls at position L1, and the control signal 30 may be intended to adjust the display settings within the first range R110 in the screen C100. The first switcher as the main switcher may determine that the control signal 30 controls the first switcher 110 as described above, and control the first switcher 110 to adjust the display settings within the first range R110 in the screen C100 according to the content of the control signal 30. When the position information of the control signal 30 falls at position L2, it falls within both the first host range R111 and the second host range R121. At this time, the first switcher 110 may first determine that the control signal 30 controls the first switcher 110 according to the first depth value being less than the second depth value, and then the first switcher 110 may determine that the control signal 30 controls the first host 111 according to the position information of the control signal 30 falling within the first host range R111 (as shown by arrow 31 in FIG. 1).

FIG2B is a schematic diagram of another operation example of a usage situation. Referring to FIG1 and FIG2B , the following description will be based on the first switch 110 being set such that if the first depth value is greater than the second depth value, the second range R120 covers the first range R110 in the overlapped area. However, the present invention is not limited thereto. The first switch 110 may also be set such that if the first depth value is less than the second depth value, the second range R120 covers the first range R110 in the overlapped area.

As shown in FIG. 2B , the positions L1, L2, and L3 fall within the overlapping region of the first range R110 and the second range R120. More specifically, the position L2 also falls within the overlapping region of the first host range R111 and the second host range R121, and the position L3 also falls within the second host range R122. In this operation example, when the position information of the control signal 30 falls within the position L1, the first switching device 110 can determine that the control signal 30 controls the second switch 120 based on the first depth value being greater than the second depth value. Similarly, when the position information of the control signal 30 falls within the position L2, the first switching device 110 can determine that the control signal 30 controls the second host 121 based on the first depth value being greater than the second depth value. Similarly, when the position information of the control signal 30 falls within the position L3, the first switching device 110 can determine that the control signal 30 controls the second host 122 based on the first depth value being greater than the second depth value.

The above is only an example and is not intended to limit the present invention. In other embodiments, the switching system of the present invention may include more switches. For example, in some embodiments, the switching system of the present invention may include a daisy chain formed by three or more switches connected, and the switch that receives the control signal from the outside serves as the master switch, and the remaining switches serve as slave switches. In this way, the switching system of the present invention can adjust the number of switches at will, so that the number of hosts to be controlled can be expanded or reduced according to the needs of the user.

In some embodiments, the first switch 110 can adjust the first depth value and the second depth value according to the control signal 30. For example, in one embodiment, the control signal 30 can be a mouse signal, the first depth value can be 1, the second depth value can be 2, and the first range R110 covers the second range R120. When the position information of the control signal 30 falls within the second range and is not within the overlapping area of the first range and the second range, the first switch can determine that the control signal 30 controls the second switch 120, and adjust the first depth value to 2, and adjust the second depth value to 1.

FIG3 is a schematic diagram of another operation example of the present invention. Referring to FIG1 and FIG3, in this operation example, the first integrated screen data generated by the first switch 110 according to the first screen data 111a may include a first reference coordinate system defined by a first reference point REF1, a direction _X1 , and a direction _Y1 ; the second integrated screen data 120a may include a second reference coordinate system defined by a second reference point REF2, a direction _X2 , and a direction _Y2 ; and the display data 100a may include a total coordinate system defined by an origin ORI, a direction _X3 , and a direction _Y3 . In this operation example, the first switch 110 sets the first reference point REF1 as the vertex at the lower left of the first range R110, sets the second reference point REF2 as the vertex at the upper right of the second range R120, and sets the vertex at the lower left of the screen C100 as the origin ORI. However, the present invention is not limited to this. In other operation examples, the first switch 110 can set any vertex in the first range R110 as the first reference point REF1 (not shown), set any vertex in the second range R120 as the second reference point REF2 (not shown), and set any vertex in the screen C100 as the origin ORI (not shown).

In this operation example, the first switching device 110 sets the first range R110 and the second range R120 in the total coordinate system defined by the origin ORI, the direction _X3 , and the direction _Y3 . Specifically, the first switching device 110 can set the coordinates of the first reference point REF1 and the second reference point REF2 in the total coordinate system, and set the rectangular range opened by the first reference point REF1 extending to the direction _X1 and the direction _Y1 by a certain length as the first range R110, and the rectangular range opened by the second reference point REF2 extending to the direction _X2 and the direction _Y2 by a certain length as the second range R120. In this operation example, the first reference point REF1, the direction _X1 , and the direction _Y1 define the first reference coordinate system; the second reference point REF2, the direction _X2 , and the direction _Y2 define the second reference coordinate system. It should be noted that FIG. 3 is only for illustration and is not intended to limit the specific directions of the coordinate axes of the first reference coordinate system and the second reference coordinate system.

In this operation example, within the first range R110, the coordinates of the first reference coordinate system and the coordinates of the global coordinate system can be converted to each other. For example, the coordinate value of the first reference point REF1 in the global coordinate system can be (50, 400), and the coordinate value of the first reference point REF1 in the first reference coordinate system can be (0, 0); similarly, the coordinate value of the position L4 in the global coordinate system can be (500, 410), and the coordinate value of the position L4 in the first reference coordinate system can be (450, 10).

In this operation example, within the second range R120, the coordinates of the second reference coordinate system and the coordinates of the global coordinate system can be converted to each other. For example, the coordinate value of the second reference point REF2 in the global coordinate system can be (950, 430), and the coordinate value of the first reference point REF2 in the second reference coordinate system can be (0, 0); similarly, the coordinate value of the position L4 in the global coordinate system can be (500, 410), and the coordinate value of the position L4 in the second reference coordinate system can be (450, 20).

The following example of coordinate conversion between the overall coordinate system and the second reference coordinate system is used to illustrate the effectiveness of coordinate conversion. In one usage scenario, by converting the coordinates of the second reference coordinate system and the overall coordinate system, when the first switching device 110 serves as the main switch and determines that the control signal 30 controls the second switch 120 based on the position information of the control signal 30 being located at position L4, the first switching device 110 can convert the coordinate value of position L4 in the overall coordinate system into the coordinate value of position L4 in the second reference coordinate system, and use the coordinate value of position L4 in the second reference coordinate system as the position information of the control signal 30 to transmit the control signal 30 to the second switch 120. In this way, the second switch 120 can directly determine the position of the control signal 30 in the second range R120 without having to determine by itself which coordinate value of the second reference coordinate system the coordinate value of position L4 in the overall coordinate system corresponds to.

It should be understood that the above is only an example, and depending on the user's control, the position information of the control signal 30 can be any coordinate value in the overall coordinate system. For example, if the position information of the control signal 30 and the first reference point REF1 are both coordinates (50, 400) in the overall coordinate system, the first switch 110 can determine that the control signal 30 controls the first switch 110, and convert the position information of the control signal 30 into the coordinates (0, 0) of the first reference coordinate system. If the position information of the control signal 30 and the position L4 are both coordinates (500, 410) in the overall coordinate system, the first switch 110 can determine that the control signal 30 controls the first switch 110 based on the first depth value and the second depth value (for example but not limited to, the first depth value is less than the second depth value), and convert the position information of the control signal 30 into the coordinates (450, 10) of the first reference coordinate system. In other words, the master switch can comprehensively consider the range in which the position information 30 falls and the depth values of each switch in the switching system to determine whether to convert the position information of the control signal 30 into the coordinate value of the reference coordinate system corresponding to a specific switch.

Similarly, in this operation example, if the position information of the control signal 30 and the second reference point REF2 are both coordinates (950, 430) in the overall coordinate system, the first switch 110 can determine that the control signal 30 controls the second switch 120, and convert the position information of the control signal 30 into the coordinates (0, 0) of the second reference coordinate system. If the position information of the control signal 30 and the position L4 are both coordinates (500, 410) in the overall coordinate system, the first switch 110 can determine that the control signal 30 controls the second switch 120 according to the first depth value and the second depth value (for example but not limited to, the first depth value is less than the second depth value), and convert the position information of the control signal 30 into the coordinates (450, 20) of the second reference coordinate system.

FIG4 is a schematic diagram of another operation example of the present invention. Referring to FIG1 and FIG4, in this operation example, the first switching device 110 can adjust the length and/or width of the first range R110 according to the control signal 30. For example, the control signal 30 can be a mouse signal, and when the mouse is dragged from position L5 to position L6, the first range R110 is adjusted to a first range R110' with a smaller length and width, so that the user can use the mouse to adjust the size of the first range.

As shown in FIG. 4 , similarly, in this operation example, the second range R120 can be adjusted to a second range R120' having a larger length and width.

FIG5 is a schematic diagram of another operation example of the present invention. Referring to FIG1 and FIG5, in this operation example, the control signal 30 may be a mouse signal of pressing and holding the first reference point REF1 and dragging along the path 40, and the first switching device 110 may move the position of the first range R110 in the total coordinate system of the screen C100 according to the control signal 30. Similarly, as shown in FIG5, when the control signal 30 is a mouse signal of dragging the second reference point REF2 along the path 50, the first switching device 110 may move the position of the first range R110 in the total coordinate system of the screen C100 according to the control signal 30. Therefore, the user can use the mouse to move the first range and the second range in the screen C100.

Fig. 6 is a schematic diagram of a switching system 200 according to another embodiment of the present invention. Referring to Fig. 6, in this embodiment, the first switch 210 is connected to the first display 21, and the first switch 220 is connected to the first display 22. In other words, each switch of the switching system 200 is connected to a display.

As shown in FIG. 7 , in this embodiment, the second display 22 is located in front of the first display 21 , so the second display 22 covers a corner of the first display 21 to form an overlapping area.

In the present embodiment, the first switching device 210 sets a first depth value, a first range, a second depth value, and a second range in a general coordinate system. Referring to FIG. 7 , the general coordinate system is defined by, for example, an origin VORI, a direction _X4 , and a direction _Y4 , and covers the positions of the first display 21 and the second display 22. The first range and the first depth value correspond to the first integrated screen data 210a, and the second range and the second depth value correspond to the second integrated screen data 220a. In the present embodiment, the user can set the first range and the second range to respectively match the size and position of the first display 21 and the second display 22 through the first switch 210.

In this embodiment, when the position information of the control signal 30 falls at position L7, that is, falls within the overlapping area of the first range and the second range, the first switch 210 can determine whether the control signal 30 controls the first switch 210 or the second switch 220 according to the first depth value and the second depth value. For example, when the user wants to control the first switch 210 when the position information of the control signal 30 falls at L7, the user can set the first depth value and the second depth value through the first switch 210, so that the first switch 210 determines that the control signal 30 controls the first switch 210 when its position information falls at L7.

Referring to FIG. 6 and FIG. 7 , in one embodiment, the user can set the first range and the second range to respectively match the size and position of the first display 21 and the second display 22 through the first switch 210. When the second display 22 covers part of the first display 21 to form an overlapping area as shown in FIG. 6 , the user can only see the screen of the overlapping area of the first range and the second range on the second display 22. At this time, if the user wants to view the screen content of the first integrated screen data, the first depth value and the second depth value can be set through the first switch 210, and the first switch 110 can change the content of the overlapping area corresponding to the second integrated screen data 220a to the corresponding content of the first integrated screen data 210a (i.e., the content of the overlapping area corresponding to the first integrated screen data 210a). As shown in FIG. 7 , the first switch 110 changes the content of the overlapping area corresponding to the second integrated screen data 220a to the corresponding content of the first integrated screen data 210a, so the display 22 displays the screen content of the first integrated screen data in the overlapping area instead of displaying the content of the second integrated screen data.

Alternatively, in the embodiment shown in FIG. 6 , the first switch 210 and the second switch 220 may each be connected to at least one display (not shown), and the switching system 200 may adjust the first integrated screen data 210a and the second integrated screen data 220a to be output to a specific number of displays according to a second control signal (not shown) generated by the first switch 210 or the second switch 220. For example, in a usage scenario, the first switch 210 and the second switch 220 may be connected to a total of nine displays, and the first switch 210 or the second switch 220 may have a button or a knob. When the user manipulates the button or knob of the first switch 210 or the second switch 220, the first switch 210 or the second switch 220 may generate a second control signal and adjust the first integrated screen data 210a and the second integrated screen data 220a to be output to four (2*2 matrix) or nine (3*3 matrix) of the aforementioned nine displays according to the second control signal. The present invention is not limited to this. In addition to the first switch 210 or the second switch 220 having a button or a knob, in another embodiment, the first switch 210 or the second switch 220 can also be controlled by the user through a touch interface, thereby adjusting the output of the first integrated screen data 210a and the second integrated screen data 220a to each display.

The present invention has been disclosed as above by way of embodiments, but they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the patent claims of the application.
