Embodiment Construction

[0039] The following is attached Figure 1-3 The application is described in further detail.

[0040] The KVM switch is one of the commonly used switches at present. Among them, KVM is the abbreviation of keyboard (Keyboard), monitor (Video), and mouse (Mouse). Simply put, a KVM switch allows system administrators to control the computer peripherals of multiple servers or computer hosts through a set of keyboards, mice, and monitors.

[0041] Existing KVM switches generally include two display interfaces 2 for connecting displays and several host display interfaces 1 for connecting to computer hosts. After the two display interfaces 2 are connected to the display, one display is used as the main screen, and the other is used as the expansion screen to display the audio and video data input from the host computer to the display interface 1 of the host computer respectively. At the same time, the existing host display interface 1 switching mode generally adopts a switch switc...

Abstract

The invention relates to a KVM control system and a KVM display switching control method, and relates to the field of computer control. The KVM control system comprises at least two host display interfaces used for being connected with a host; a display interface used for connecting a display; a main control MCU used for acquiring display response information output by the display interface basedon the received reading operation signal, wherein the main control MCU also acquires audio and video data output by the selected host display interface based on the received switching operation signal, and outputs the audio and video data to the interface connected with the display; a virtual machine chip used for acquiring and storing the display response information read by the main control MCU,and answering the inquiry of the host connected to the host display interface through a response pin group based on the display response information; a reading trigger piece used for outputting reading operation information to the main control MCU; and a switching trigger piece used for outputting switching operation information to the main control MCU. The system and the method have the effect that the display contents of the display are consistent before and after switching.

Description

technical field [0001] The invention relates to the field of computer control, in particular to a KVM control system and a KVM display switching control method. Background technique [0002] The KVM switch is one of the commonly used switches at present. Among them, KVM is the abbreviation of keyboard (Keyboard), monitor (Video), and mouse (Mouse). Simply put, a KVM switch allows system administrators to control the computer peripherals of multiple servers or computer hosts through a set of keyboards, mice, and monitors. [0003] The Chinese patent with publication number CN110888538A discloses a KVM switching circuit and a switcher, the switching circuit includes a plurality of Type-C connectors, a CC control module, a signal switching / synchronization module, at least two input device interfaces, a plurality of different Type-C communication interface; Type-C connector is used to connect the host device to realize two-way communication between the signal switching / synchro...
