KVM terminal for realizing networking and system

Abstract

The invention provides a KVM terminal for realizing networking and a system. A USB OTG module, a dynamic random access memory, a flash memory and a gigabit network interface module are respectively connected with a processor. The gigabit network interface module is connected with an RJ45 interface. The processor is connected with a VGA interface through a VGA analog-to-digital conversion module. The processor is also connected with the DVI interface. The same hardware module is used, and the module is divided into KVM terminals for configuration through programming two programs. After the twoKVM terminals are interconnected, one KVM terminal can be responsible for accessing a USB and VGA or DVI display signal with a controlled unit, and the other KVM terminal can be used for accessing a USB keyboard and mouse, a USB storage device and a display, and remote operation of a user is realized. The first KVM terminal and the second KVM terminal are in network interconnection through the gigabit switch, multiple users can be facilitated, any controlled unit in the network segment can be accessed and controlled mostly according to the IP address, and therefore KVM networking is achieved.

Description

technical field [0001] The invention relates to the technical field of networked KVM, in particular to a terminal and system for realizing networked KVM. Background technique [0002] A KVM switch (English: KVM switch), generally referred to as KVM, also known as a multi-computer switch, is a computer device that allows users to control multiple computers through a set of keyboards, display screens, and mice. [0003] The official name of KVM switch is multi-computer switch or KVM SWITCH. Simply put, a KVM switch allows system administrators to control the computer peripherals of multiple servers or computer hosts through a set of keyboards, monitors and mice, which means that only one person can interact with all computers, of course, at one time Can only interact with one. In addition to saving the overhead of multiple keyboards and monitors, a switcher can free up more desk space. [0004] At present, most KVM switches are used in office areas. Users control multiple c...

Causes lack of information interaction, lack of information sharing, and inability to communicate with each other based on the KVM model

[0005] Although some areas have realized the interconnection of the office LAN, they have not been able to communicate with each other based on the KVM mode, and cannot communicate with each other based on video information and display information.

In the process of interconnection, it is also impossible to confirm the interconnection security based on the KVM mode, leaving a security risk for the Internet
