Keyboard and mouse equipment sharing method

Abstract

The invention discloses a keyboard and mouse equipment sharing method, which comprises the following steps of: 1, acquiring keyboard and mouse data in a channel system; 2, enabling the keyboard and mouse data to form a network data frame, and sending the network data frame to a bid-winning kylin operating system; 3, enabling the bid-winning kylin operating system to analyze the network data frame; 4, judging whether the network data frame is a keyboard event or a mouse event by the bid-winning kylin operating system, and calling a corresponding data processing function for processing according to the event type; and 5, responding to the processed keyboard and mouse event by the bid-winning kylin operating system, and performing sharing. According to the method, through a self-defined network protocol and a special algorithm, the problems of data transmission and data universality between the bid-winning kylin operating systems in a keyboard and mouse data field under a channel system are solved, and a keyboard and mouse equipment sharing function between an embedded system and a desktop system is realized; and sharing of input equipment under a domestic operating system is realized in a software mode.

Description

technical field [0001] The invention belongs to the technical field of computer control, in particular to a keyboard and mouse device sharing method. Background technique [0002] Existing methods for sharing keyboard and mouse devices can be divided into two categories, one is switching through hardware, such as a KVM switch; the other is through software, such as sharing keyboard and mouse devices through the RDP protocol or VNC protocol based on the network. [0003] A KVM switch is also called a multi-computer controller. One KVM switch can control multiple computers or servers. The control port of the KVM switch is mainly used to connect the USB port of the keyboard and mouse and the VGA port of the monitor. In the case of hardware connection, if the number of hosts to be shared is large, the hardware design complexity, design cost and switching logic complexity will increase, and the reliability will decrease at that time. [0004] RDP (Remote Display Protocol) protoc...

Problems solved by technology

[0006] Since the RDP protocol and VNC protocol are only applicable to the desktop operating system, the Tao system is an embedded operating system without a graphical desktop, and the keyboard and mouse event code values ​​​​under the Tao system are not universal, so that the Tao system cannot use the above two protocols.
