Description
Technical Field
The present invention relates to a switching system, and more particularly, to a switching system including a plurality of switching devices.
Background
A set of keyboard, display and mouse can be used to control multiple hosts through the KVM switch. However, because of the limited ports of a single KVM switch, it may not be possible to satisfy the user's need to control a large number of hosts. If a KVM switch with a larger number of ports is to be provided to consumers, the KVM switch should be designed separately according to the required specifications, and the complexity of the design will be increased correspondingly as the specification changes more. In addition, the more ports the KVM switches require, the more production costs, which can lead to higher pricing of the product and impact consumer purchase options. In addition, when the KVM switch is to be controlled, the keyboard and the mouse should be connected to the back of the KVM to be controlled to perform the setting, so that when a plurality of KVM switches are connected to each other, if the KVM switches should be individually set, the keyboard and the mouse should be individually connected to each KVM switch to perform the controlling setting, which is inconvenient. Accordingly, it is a challenge in the art to obtain a solution to increase the number of controllable hosts without significantly changing the specifications of the KVM switch.

Fig. 1 is a schematic diagram of a switching system 100 according to an embodiment of the invention. Referring to FIG. 1, in one embodiment, a 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 the present embodiment, the first switch 110 is connected to the first host 111, and receives the first frame data 111a from the first host 111. The first switch 110 generates first integrated frame data (not shown) according to the first frame data 111a received from the first host 111. The first switch 110 may have a processing element such as a cpu, a microprocessor, a logic unit, or a programmable chip, and generates first integrated frame data according to the first frame data 111a through the processing element. It should be noted that in other embodiments, the first switch 111 can be connected to other numbers of first hosts, and the invention is not limited to the number of first hosts connected to the first switch 110.
As shown in fig. 1, in the present embodiment, the switching system 100 further includes a second switch 120. The second switch 120 is connected to the second host 121 and the second host 122. The second switcher 120 receives the second picture data 121a from the second host 121 and the second picture data 122a from the second host 122. Here, similar to the first switch 110, the second switch 120 may generate the second integrated frame data 120a according to the second frame data 121a and the second frame data 122a through the processing elements included therein. In other embodiments, the second switch 120 can be connected to other numbers of second hosts, which is not limited to the present invention.
As shown in fig. 1, the first switch 110 receives the second integrated frame data 120a from the second switch 120, and generates the display data 100a according to the first integrated frame data and the second integrated frame data 120 a; however, the present invention is not limited thereto, and in other embodiments, the first switch 110 may not generate the display data 100a, as will be described in detail in the following another embodiment.
In the present embodiment, the first switch 110 outputs the display data 100a to the display 20, so that the display 20 displays a frame according to the content of the display data 100 a. In addition, the first switch 110 acts as a master switch (master) receiving 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 frame data 111 (or the first integrated frame data) from the first switch 110, and the second switch 120 generates the display data 100a according to the first frame data 111 (or the first integrated frame data) and the second integrated frame data 120a, and then transmits the display data to the display 20 for displaying. In this embodiment, the second switch 120 is used as a master switch, receives the control signal 30, and the first switch 110 is used as a slave switch and is controlled by the second switch 120. In other words, the first switch 110 or the second switch 120 is set as the master switch according to the user's requirement, and the other switches can be set as the slave switches, so as to meet the field requirement.
An example of the operation of controlling each host in the switching system 100 under different use conditions is described below with reference to fig. 2A and 2B.
Fig. 2A is a schematic diagram of an operation example of the present invention. Referring to fig. 1 and 2A, in the present operation example, the display 20 displays the screen C100 as shown in fig. 2A according to the display data 100 a. 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 further includes a first depth value (not shown) and a second depth value (not shown). In this embodiment, the first range R110 and the first depth value correspond to the first integrated frame data; the second range R120 and the second depth value correspond to the second integrated frame data 120a; the first host range R111 corresponds to the first screen data 111a; the second host range R121 corresponds to the second picture data 121a; the second host range R122 corresponds to the second picture 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 shown 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 smaller than the second depth value, the first range R110 in the overlapping region 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 region covers the second range R120. The following description is an explanation of the present operation example, assuming that the first depth value is smaller than the second depth value, the setting that the first range R110 covers the second range R120 in the overlapping region.
In this embodiment, 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 (L1, L2 may be specific coordinates) shown in fig. 2A. The first switch 110 determines which device the control signal 30 controls 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 can 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 be used as a master switch to determine that the control signal 30 controls the first switch 110 according to the position information of the control signal 30 falling within the first range R110, and then the first switch 110 controlled by the control signal 30 determined by the master switch 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, and transmit the control signal to the first host 111 (as indicated 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 may determine that the control signal 30 controls the second switch 120 and transmit the control signal to the second switch 120 (as indicated 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 R121, the first switch 110 may act as a master switch and determine that the control signal 30 controls the second switch 120 according to the position information of the control signal 30 falling within the second range R120, and then determine that the second switch 120 controlled by the control signal 30 via the master switch may determine that the control signal 30 controls the second host 121 according to the position information of the control signal 30 falling within the second host range R122 and transmit the control signal to the second host 121 (as indicated by arrow 32 and arrow 33 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 R122, the first switch 110 may be used as a master switch and determine that the control signal 30 controls the second switch 120 according to the position information of the control signal 30 falling within the second range R120, and then the second switch 120 determined by the master switch to be controlled by the control signal 30 may determine that the control signal 30 controls the second host 122 according to the position information of the control signal 30 falling within the second host range R122 and transmit the control signal to the second host 122 (as indicated by arrow 32 and arrow 34 in fig. 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 frame C100 will be described in detail with reference to fig. 3. In this embodiment, when the position information of the control signal 30 falls within the position L1, it falls within both the first range R110 and the second range R120, and at this time, the first switching device 110 may determine that the control signal 30 controls the first switch 110 according to the first depth value being smaller than the second depth value. For example, in a use scenario, the position information of the control signal 30 falls at the position L1, and the control signal 30 may be intended to adjust the display setting in the first range R110 in the frame C100, and the first switch as the master switch may determine that the control signal 30 controls the first switch 110 as described above, and control the first switch 110 to adjust the display setting in the first range R110 in the frame C100 according to the content of the control signal 30. When the position information of the control signal 30 falls within the position L2, it falls within both the first host range R111 and the second host range R121, and at this time, the first switching device 110 may determine that the control signal 30 controls the first switch 110 according to the first depth value being smaller than the second depth value, and then the first switch 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 indicated by an arrow 31 in fig. 1).
Fig. 2B is an operational illustration of another use case. Referring to fig. 1 and 2B, the first switch 110 is set to cover the first range R110 in the overlapping area by the second range R120 if the first depth value is greater than the second depth value, but the present invention is not limited thereto, and the first switch 110 may also be set to cover the first range R110 in the overlapping area by the second range R120 if the first depth value is less than the second depth value.
As shown in fig. 2B, the position L1, the position L2, and the position L3 fall within the overlapping area of the first range R110 and the second range R120, more specifically, the position L2 also falls within the overlapping area 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 embodiment, when the position information of the control signal 30 falls at the position L1, the first switching device 110 can determine that the control signal 30 controls the second switch 120 according to the first depth value being greater than the second depth value. Similarly, when the position information of the control signal 30 falls at the position L2, the first switching device 110 may determine that the control signal 30 controls the second host 121 according to the first depth value being greater than the second depth value. Similarly, when the position information of the control signal 30 falls at the position L3, the first switching device 110 can determine that the control signal 30 controls the second host 122 according to the first depth value being greater than the second depth value.
The above is merely exemplary and is not intended to limit the present invention, and 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 (daise chain) formed by three or more switches connected, and switches receiving control signals from the outside as master switches and the remaining switches as slave switches (slave). Therefore, the switching system of the invention can randomly adjust the number of the switches, thereby being capable of expanding or reducing the number of the hosts to be controlled according to the requirements of users.
In some embodiments, the first switch 110 may 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 may be a mouse signal, the first depth value may be 1, the second depth value may be 2, and the first range R110 may cover 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 may 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.
Fig. 3 is a schematic diagram of another operation example of the present invention. Referring to fig. 1 and 3, in the present operation example, the first switch 110 generates the first integrated frame data according to the first frame data 111a, which includes a first reference point REF1 and a direction X 1 Direction Y 1 A first reference frame defined; the second integrated frame data 120a may include a second reference point REF2, a direction X 2 Direction Y 2 A second reference frame defined; the display data 100a may include a display data from an origin ORI and a direction X 3 Direction Y 3 A defined total coordinate system. In this operation example, the first switch 110 sets the first reference point REF1 as the top left of the first range R110, the second reference point REF2 as the top right of the second range R120, and the bottom left of the screen C100 as the origin ORI. However, the present invention is not limited thereto, and in other embodiments, the first switch 110 may set any vertex of the first range R110 as the first reference point REF1 (not shown), any vertex of the second range R120 as the second reference point REF2 (not shown), and any vertex of the frame C100 as the origin ORI (not shown).
In this operation example, the first switching device 110 is located at the origin ORI and in the direction X 3 Direction Y 3 The first range R110 and the second range R120 are set in the defined total coordinate system. Specifically, the first switching device 110 can set coordinates of the first reference point REF1 and the second reference point REF2 in the total coordinate system, and set a direction X from the first reference point REF1 1 Direction Y 1 Each rectangular range extending for a certain length is a first range R110, and extends from a second reference point REF2 to a direction X 2 Direction Y 2 The rectangular extent of each of the extended lengths is the second extent R120. In this example of operation, a first reference pointREF1, direction X 1 Direction Y 1 Defining a first reference coordinate system; second reference point REF2, direction X 2 Direction Y 2 A second reference coordinate system is defined. It should be noted that the third drawing is merely an illustration, and is not intended to limit the specific orientations of the coordinate axes of the first reference frame and the second reference frame.
In this embodiment, the coordinates of the first reference coordinate system and the coordinates of the total coordinate system are mutually convertible within the first range R110. For example, the coordinate value of the first reference point REF1 in the total coordinate system may be (50,400), while the coordinate value of the first reference point REF1 in the first coordinate system may be (0, 0); similarly, the coordinate value of the position L4 in the total coordinate system may be (500,410), while the coordinate value of the position L4 in the first reference coordinate system may be (450,10).
In this embodiment, the coordinates of the second reference coordinate system and the coordinates of the total coordinate system are mutually convertible within the second range R120. For example, the coordinate value of the second reference point REF2 in the total coordinate system may be (950,430), while the coordinate value of the first reference point REF2 in the second coordinate system may be (0, 0); similarly, the coordinate value of the position L4 in the total coordinate system may be (500,410), while the coordinate value of the position L4 in the second reference coordinate system may be (450,20).
In a use scenario, by converting the coordinates of the second reference coordinate system to the coordinates of the second reference coordinate system, when the first switching device 110 is used as a master switch and determines that the control signal 30 controls the second switching device 120 according to the position information of the control signal 30 being located at the position L4, the first switching device 110 can convert the coordinate value of the position L4 in the total coordinate system into the coordinate value of the position L4 in the second reference coordinate system, and the control signal 30 is transmitted to the second switching device 120 by taking the coordinate value of the position L4 in the second reference coordinate system as the position information of the control signal 30, so that the second switching device 120 can directly determine the position of the control signal 30 in the second range R120 without automatically determining the position of the position L4 in the total coordinate system corresponding to the position value of the second reference coordinate system.
It should be understood that the above is merely exemplary, and the position information of the control signal 30 may be any coordinate value in the total coordinate system according to the user's manipulation. For example, if the position information of the control signal 30 and the first reference point REF1 are the coordinates (50,400) in the total 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) in the first reference coordinate system. If the position information of the control signal 30 and the position L4 are both coordinates in the total coordinate system (500,410), the first switch 110 can determine that the control signal 30 controls the first switch 110 according to the first depth value and the second depth value (e.g., without limitation, the first depth value is smaller than the second depth value), and convert the position information of the control signal 30 into the coordinates of the first reference coordinate system (450,10). In other words, the master switch can comprehensively consider the range of the position information 30 and the depth value of each switch in the switching system 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 the present operation example, if the position information of the control signal 30 and the second reference point REF2 are the coordinates (950,430) in the total 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) in the second reference coordinate system. If the position information of the control signal 30 and the position L4 are both coordinates in the total coordinate system (500,410), 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 (e.g., without limitation, the first depth value is smaller than the second depth value), and convert the position information of the control signal 30 into coordinates in the second coordinate system (450,20).
Fig. 4 is a schematic diagram of another operation example of the present invention. Referring to fig. 1 and 4, in the present operation example, the first switching device 110 may adjust the length and/or the width of the first range R110 according to the control signal 30. For example, the control signal 30 may be a mouse signal, and the first range R110 is adjusted to have a smaller length and width of the first range R110' when the mouse is dragged from the position L5 to the position L6, so that the user can adjust the size of the first range using the mouse.
Similarly, in the present operation example, the second range R120 can be adjusted to a second range R120' having a larger length and width, as shown in fig. 4.
Fig. 5 is a schematic diagram of another operation example of the present invention. Referring to fig. 1 and 5, in the present embodiment, the control signal 30 may be a mouse signal that holds the first reference point REF1 and drags 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 frame C100 according to the control signal 30. Similarly, as shown in fig. 5, when the control signal 30 is a mouse signal dragging the second reference point REF2 along the path 50, the first switching device 110 can move the position of the first range R110 in the total coordinate system of the frame C100 according to the control signal 30. Therefore, the user can move the first range and the second range in the screen C100 using the mouse.
Fig. 6 is a schematic diagram of a switching system 200 according to another embodiment of the invention. Referring to fig. 6, in the present embodiment, the first switch 210 is connected to the first display 21, 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.
In the present embodiment, as shown in fig. 7, the second display 22 is located in front of the first display 21, so that 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 total coordinate system. Referring to FIG. 7, the total coordinate system is, for example, the coordinate system from the origin VORI to the direction X 4 Direction Y 4 Defined 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 frame data 210a, and the second range and the second depth value correspond to the second integrated frame data 220a. In the present embodiment, the user can set the first range and the second range to respectively correspond to the size and the position of the first display 21 and the second display 22 through the first switch 210.
In the present embodiment, when the position information of the control signal 30 falls in the position L7, that is, falls in the overlapping area of the first range and the second range, the first switch 210 can determine the control signal 30 to control 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 in 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 the position information falls in L7.
Referring to fig. 6 and 7, in one embodiment, a user can set the first range and the second range to respectively correspond to the size and the position of the first display 21 and the second display 22 through the first switch 210. When the second display 22 covers a portion of the first display 21 to form an overlapping area as shown in fig. 6, the user can only see the images of the overlapping areas of the first and second areas on the second display 22. At this time, if the user wants to view the content of the first integrated frame data, the first switch 210 can set the first depth value and the second depth value, and the first switch 110 can change the content of the overlapping region corresponding to the second integrated frame data 220a to the corresponding content of the first integrated frame data 210a (i.e. the content of the overlapping region corresponding to the first integrated frame data 210 a) according to the first depth value and the second depth value. As shown in fig. 7, the first switch 110 changes the content of the overlapping area corresponding to the second integrated frame data 220a to the corresponding content of the first integrated frame data 210a, so the display 22 displays the frame content of the first integrated frame data in the overlapping area instead of displaying the content of the second integrated frame data.
Alternatively, in the embodiment shown in fig. 6, the first switch 210 and the second switch 220 may be respectively connected to at least one display (not shown), and the switching system 200 may adjust the first integrated frame data 210a and the second integrated frame data 220a to be output to a specific number of displays according to the 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 nine displays in total, and the first switch 210 or the second switch 220 may have buttons or knobs, when the user manipulates the buttons or knobs 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 integration screen data 210a and the second integration screen 220a to output to four (2×2 matrix) or nine (3*3 matrix) of the nine displays according to the second control signal. In addition to the first switch 210 or the second switch 220 having buttons or knobs, in another embodiment, the first switch 210 or the second switch 220 can be manipulated by a user through a touch interface, so that the first integrated screen data 210a and the second integrated screen 220a can be adjusted to be output to each display.
