Embodiment 1

[0049] refer to figure 1 , is an AUX automatic answering device of a KVM switch disclosed by the present invention, the KVM switch is connected with a display 30 and several hosts 40, and the AUX automatic answering device includes a control board 10 and an FPGA module 20. The control board 10 is used to switch the channel of the KVM switch, and control the display 30 to be connected to the host computer 40 on the switched channel. The FPGA module 20 is used for virtualizing multiple display AUX agents, and for automatically assigning a virtual display AUX agent to connect to the host 40 when the host 40 is not connected to the display 30 . It should be noted that the technical solution of the present application is also applicable to the situation that other programmable devices (such as PLD, CPLD, single-chip microcomputer, microprocessor, etc.) are used to realize it except FPGA.

[0050] refer to figure 1 , in this embodiment, there are 4 hosts 40, that is, there are 4 v...

Embodiment 2

[0060] refer to figure 2 , is the AUX automatic answering method of a kind of KVM switcher disclosed by the present invention, comprises the following steps:

[0061] Step S1, adding an FPGA-based automatic answering device on the basis of the KVM switch;

[0062] It should be noted that the automatic answering device is also applicable to the use of other programmable devices other than FPGA (such as PLD, CPLD, single-chip microcomputer, microprocessor, etc.) to realize the situation.

[0063] Step S2, building an AUX reading module, a plurality of AUX agents and a plurality of switching switches inside the FPGA, and connecting the FPGA to a switching button module;

[0064] Wherein, the switching switch is connected to the AUX agent in one-to-one correspondence, and is used to control the corresponding host to be connected to the corresponding AUX agent or directly connected to the display;

[0065] Step S3, when the automatic answering device is powered on, the AUX readi...

Abstract

The invention discloses an AUX automatic answering device and method of a KVM switch, relates to the technical field of computer control, and aims at solving the problem of inconvenient use of the existing DisplayPort type KVM switch. The technical scheme includes an FPGA module and a control board. The control board is used for switching the channels of the KVM switcher and controlling the display to be connected with the host computer on the switched channels. The FPGA module is used for virtualizing a plurality of display AUX proxies. The FPGA module is also used for automatically assigninga virtual display AUX proxy to connect the host when the host is not connected with the display. The display AUX agent is used for communicating with the display card of the corresponding host computer and enabling the display card of the host computer to complete the initialization process correctly without manual intervention, so that the ease of use of the DisplayPort KVM switch can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to an AUX automatic answering device and method of a KVM switch. Background technique [0002] KVM is an acronym for Keyboard Video Mouse. A KVM switch is a commonly used device in computer host management. It can control multiple devices with a set of keyboard, mouse and monitor. Simply put, it is to use a set of keyboards, mice and monitors to control 2, 4, 8 or even more computer hosts, and administrators can freely switch between these computer hosts to improve work efficiency. [0003] A DisplayPort KVM switch is a KVM switch whose video interface is in the form of DisplayPort, and is usually used to connect to a host whose graphics card interface is DisplayPort. Similar to it are DVI type KVM switch, HDMI type KVM switch, etc. [0004] Since the KVM switch has only one monitor interface, only one host can be connected to the monitor at a time. If several hosts sta...
