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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a switching method of a remote input device according to an embodiment of the present invention, and referring to fig. 1, the switching method may include:
s10: the method comprises the steps that a local PC monitors whether a display picture of a remote PC exists on large-screen display equipment or not;
specifically, the large-screen display device is respectively connected with a local PC and a remote PC, can display signals of a plurality of PCs and supports signal superposition. When only the display screen of the local PC exists on the large-screen display device, input device switching is not required. If the display screen of the remote PC exists on the large-screen display device, input device switching may be required, that is, an operation signal of the input device is switched to the remote PC to control the remote PC. Therefore, the local PC first needs to determine whether the display screen of the remote PC exists on the large-screen display device, that is, the local PC monitors whether the display screen of the remote PC exists on the large-screen display device.
In one specific embodiment, the monitoring, by the local PC, whether the display screen of the remote PC exists on the large-screen display device may include: the local PC acquires display parameters of the large-screen display equipment; the display parameters comprise a signal source for displaying a picture and a corresponding display area; and the local PC judges whether a display picture of the remote PC exists on the large-screen display equipment or not according to the display parameters.
Specifically, the large-screen display device provides a control interface and a communication protocol to the outside, and the local PC can obtain display parameters of the large-screen display device, including a signal source for displaying a picture on the large-screen display device and a corresponding display area, from the large-screen display device through the control interface according to the communication protocol. The signal source is the source of the display image. If the first display picture is from a local PC, the signal source of the first display picture is the local PC; and the second display picture is from a remote PC, and the signal source of the second display picture is the remote PC. The display area is the display position of the display picture on the large-screen display device. On the basis of obtaining the display parameters of the large-screen display device, the local PC can further judge whether a display picture of the remote PC exists on the large-screen display device according to the display parameters. The method comprises the steps that a signal source of a display picture can be analyzed, and if the signal source is only a local PC, the display picture of a remote PC does not exist on large-screen display equipment; in contrast, if the signal source contains a remote PC, the remote PC is present on the large-screen display device.
The method for acquiring the display parameters of the large-screen display equipment by the local PC is not limited uniquely, and the difference setting can be carried out according to actual needs. For example, the local PC may send a query instruction to the large-screen display device to cause the large-screen display device to return its display parameters to the local PC; or, the local PC can also receive the display parameters actively sent by the large-screen display device without sending the query instruction to the large-screen display device.
For the latter, further, after the large-screen display device sends the current display parameters to the local PC, if the subsequent display parameters are not changed, that is, the signal source and the display position of the display screen on the large-screen display device are not changed, the large-screen display device may temporarily stop sending the display parameters to the local PC until the display parameters are changed, thereby reducing data sending operations and reducing power consumption.
Optionally, the obtaining, by the local PC, the display parameter of the large-screen display device may include: and the local PC sends a query instruction to the large-screen display equipment and receives display parameters returned by the large-screen display equipment in response to the query instruction.
Specifically, the present embodiment obtains the display parameters of the large-screen display device by actively sending the query instruction by the local PC. Specifically, the local PC may first send an inquiry instruction to the large-screen display device, and then the large-screen display device returns the corresponding display parameters to the local PC after receiving and responding to the inquiry instruction, so that the local PC further executes subsequent operations.
S20: if the display picture of the remote PC exists on the large-screen display equipment, the local PC sends the display area of the remote PC on the large-screen display equipment to the KVM equipment;
specifically, if the display screen of the remote PC exists on the large-screen display device, the local PC further sends the display area of the remote PC on the large-screen display device to the KVM device, so as to provide a reference basis for the KVM device to switch the input device to the remote PC. The local PC can send the display area of the remote PC on the large-screen display device to the KVM device, and can also send the display area of the local PC on the large-screen display device to the KVM device, so that a reference basis is provided for the KVM to switch the input device to the local PC again.
S30: the KVM equipment receives the moving position of the input equipment after the display area is tracked, and judges whether the input equipment moves into the display area or not according to the moving position;
s40: if the input device moves into the display area, the KVM device switches the operation signal of the input device to the remote PC.
Specifically, after receiving the display area of the remote PC sent by the local PC, the KVM device tracks the movement position of the input device in real time, and then determines whether the input device moves into the display area of the remote PC according to the movement position of the input device. And if the input equipment moves into the display area of the remote PC, switching the operation signal of the input equipment to the remote PC so as to operate the remote PC. The input device may include a mouse, a keyboard, and the like. For example, the moving position of the mouse is tracked in real time, and whether the mouse moves into the display area of the remote PC is judged according to the moving position of the mouse. If the mouse moves into the display area, the operation signals of the mouse and the keyboard are switched to the remote PC.
After the input device is switched to the remote PC by the KVM device, if it is determined that the input device moves into the display area of the local PC by tracking the position of the input device, or after the input device is switched to the remote PC by the KVM device, if the display screen of the remote PC disappears, that is, the display screen of the remote PC is no longer displayed on the large-screen display device, the KVM device may switch the input device to the local PC again.
In addition, for the case that the display images of a plurality of remote PCs are displayed in the same display area on the large-screen display device in a superimposed manner, when the input device moves into the display area, the KVM device may switch the input device to the remote PC corresponding to the display image displayed on the display area last according to the sequence of the display time of each display image. Of course, to implement the above operation, the display parameters of the large-screen display device acquired by the local PC may include the display time of the display screen.
In addition, the above embodiments are expanded around the switching of the input device between the local PC and the remote PC, and it can be understood that the switching method provided by the present invention is also applicable to the switching of the input device between the remote PCs.
In summary, in the switching method of the remote input device provided by the present invention, the local PC monitors whether the display screen of the remote PC exists on the large-screen display device, and sends the display area corresponding to the remote PC to the KVM device when the display screen of the remote PC exists on the large-screen display device; further, the movement position of the input device on the large-screen display device is tracked by the KVM device, and when the input device moves into the display area of the remote PC, the operation signal is switched to the corresponding remote PC. The switching method can effectively realize the automatic switching of the input equipment, simplify the switching process and avoid the switching confusion.
Referring to fig. 2, fig. 2 is another method for switching a remote input device according to an embodiment of the present invention, and with reference to fig. 2, on the basis of the foregoing embodiments, the present embodiment further includes:
s50: the local PC monitors the self state in real time and judges whether the input focus is lost;
s60: if the input focus is lost, the local PC sends a switch command to the KVM device to cause the KVM device to switch the operating signal of the input device to the local PC.
Specifically, in this embodiment, the condition for switching the input device between the local PC and the remote PC and between the remote PCs is that the switching control software of the local PC is started and displayed on the large-screen display device in a full screen manner. Therefore, the local PC needs to monitor its own state in real time to determine whether the input focus is lost, that is, whether the switching control software is not displayed on the large screen display device in full screen. For example, it is determined whether window covering, window minimization, etc. has occurred. Once the local PC determines that the input focus loss occurs, a switch command is immediately sent to the KVM device to cause the KVM device to switch the operating signal of the input device to the local. Naturally, when it is determined that the input focus loss has occurred, if the input device is located in the local PC, switching is not necessary.
Further, in view of the above conditions, in the present embodiment, if the switching control software is not displayed on the large-screen display device in full screen, the KVM device does not perform input device switching even if there is a display screen of the remote PC on the large-screen display device.
The switching method of the remote input equipment provided by the embodiment can effectively reduce the influence on other operations executed by the local PC while realizing automatic switching of the input equipment.
The invention also provides a switching system of the remote input equipment, and the switching system described below can be correspondingly referred to with the switching method described above.
