Detailed description of the preferred embodiments
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 and 2, a method for KVM cross-screen auto-identification of a main RX includes a KVM host, at least two RX devices and a TX device, both of which are connected to the KVM host. The RX device is used for connecting with an external keyboard, a mouse and a display device, wherein the RX device can be connected with the display device through a video interface such as an HDMI/DVI interface and the like, and is connected with the keyboard and mouse device through a USB interface, so that the RX device can receive video data from the KVM host and send the video data to the display device for displaying, and receive operation data from the keyboard and mouse device and forward the operation data to the KVM host. The TX device is used to connect with an external video source device, which is typically a PC or server. Similarly, the TX device can also be connected to the video source device through a video interface such as HDMI/DVI, so that the TX device can collect the video data of the video source device and forward the video data to the KVM host, and receive the keyboard and mouse data forwarded by the KVM host and forward the keyboard and mouse data to the signal source. The KVM host is used to implement data exchange between the RX device and the TX device. The hosts in FIG. 1 are all KVM hosts.
The method comprises the steps that each RX device and one uniquely corresponding TX device establish communication connection through a KVM host, keyboard and mouse data transmitted between the RX device and the corresponding TX device with the connection relation are marked as HID data, and a corresponding data transmission channel is marked as an HID channel. The keyboard and mouse data transmitted between the RX device and the RX device through the KVM host are denoted as KMR data, and the corresponding data transmission channel is denoted as KMR channel. Communication between the RX device and the TX device and communication between the RX device and the RX device are defaulted to a disabled state, that is, in a default state, data transmission cannot be performed between the RX device and the TX device, and data transmission cannot be performed between the RX device and the RX device.
Meanwhile, the RX device capable of responding to the current keyboard and mouse operation is denoted as a main RX device, that is, the RX device directly connected with the keyboard and mouse is the main RX device, and the keyboard and mouse operation can be responded, but other keyboard and mouse operations cannot be responded. As shown in fig. 2, operation is performed on a keyboard and mouse directly connected to RX1 and the operation can be responded to, while the remaining keyboard and mouse operations cannot be responded to, and thus RX1 is the main RX device. And the RX device where the mouse displays on the screen of the corresponding display equipment is recorded as the current RX device. Similarly, as shown in fig. 2, assuming that the mouse is displayed on the screen of display device No. 2, the RX device (i.e., RX2) where display device No. 2 is located is the current RX device, i.e., RX2 is the current RX device. In fig. 2, each RX is connected to a corresponding TX, e.g., RX1 is connected to TX1, RX2 is connected to TX2, and the like. RXN in the figure indicates the nth keyboard and mouse device, and "keyboard and mouse" refers to keyboard and mouse device.
Detecting whether the keyboard and mouse equipment is operated, if so, sending a configuration command to a KVM host by an RX device directly connected with the keyboard and mouse equipment, and after receiving the configuration command, the KVM host establishes an HID channel between the RX device and a corresponding TX device and enables the HID channel, namely, the RX device can carry out data communication with the corresponding TX device, so that the operation of the keyboard and mouse equipment connected with the RX device can be responded, and the current main RX device is established.
Preferably, before detecting whether the keyboard and mouse device is operated, detecting whether a designated main RX device and/or a current RX device exists, if so, establishing a corresponding main RX device and a corresponding current RX device according to the designation information, and enabling a corresponding HID channel. If not, detecting whether the keyboard and mouse equipment is operated or not.
After the main RX device is established, a movement signal of the mouse in the cross screen is detected, and if the mouse moves to a display picture boundary (i.e. tries to cross the picture boundary) and moves from a current screen to another screen, the RX device where the screen to which the mouse moves is positioned serves as the current RX device. The KVM host establishes KMR channel between the previous RX device and the current RX device, establishes the HID channel where the current RX device is located, disables the HID channel where the previous RX device is located and KMR channel, and forms cross-screen configuration information. For example, when the mouse is moved from the screen where RX1 is located to the screen where RX2 is located, RX1 is the last RX device, and RX2 is the current RX device. And the HID channel and the KMR channel of RX1 are disabled (i.e., closed), the KMR channel between RX1 and RX2 and the HID channel of RX2 are enabled are established, and the updated cross-screen configuration information is sent to each RX device.
After the keyboard and mouse equipment where the main RX device is located stops operating for a preset period of time, if the keyboard and mouse where any RX device in all RX devices in the cross-screen combination is located operates again, if the operated keyboard and mouse is exactly located in the current main RX device, the cross-screen configuration information does not need to be changed, otherwise, the operated keyboard and mouse is not located in the current main RX device, the RX device where the operated keyboard and mouse is located sends a configuration instruction to the KVM host, and the KVM sets the RX device where the operated keyboard and mouse is located as the main RX device according to the received configuration instruction. For example, assume that the current master RX device is RX1, the current RX device is RX2, and the occurrence keymouse operation is RX 3. The RX3 sends a configuration command to the KVM host, and after receiving the configuration command, the KVM host sets the RX3 as the master RX device, even if the KMR channel between the RX3 and the RX2 and the HID channel where the RX2 is located are enabled, and the KMR channel between the RX1 and the RX2 is disabled.
Through the operation, in one cross-screen combination, a plurality of sets of keyboard and mouse devices connected with the RX devices can be automatically switched and used in the cross-screen combination, namely, the RX devices connected with the operated keyboard and mouse devices are automatically identified and set as main RX devices, and manual configuration is not needed.
The embodiments disclosed in this description are only an exemplification of the single-sided characteristics of the invention, and the scope of protection of the invention is not limited to these embodiments, and any other functionally equivalent embodiments fall within the scope of protection of the invention. Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
