Detailed Description
The technical solution of the present invention will be described more clearly and completely with reference to the accompanying drawings. It should be understood that the embodiments described herein are only for the purpose of explanation and are not intended to limit the present invention. All other embodiments used by others skilled in the art without making any inventive step are within the scope of the present invention.
Fig. 1 is a block diagram of a multi-keyboard-mouse cooperative control device in a distributed KVM seating system. As shown in fig. 1, the distributed KVM agent system includes several agent-side nodes S0, S1, S2 … Sn and several host-side nodes H0, H1, H2 … Hn; each KVM seat side node is connected with a set of keyboard and mouse respectively; the KVM host side node is connected with the host; the KVM seat side node and the KVM host side node are respectively connected with the switch; each seat side node comprises a keyboard and mouse data acquisition module and a keyboard and mouse message communication module; at least one of the agent side nodes comprises a keyboard and mouse data conversion calculation module, one of the nodes is selected as a calculation node, and data of all the agent side nodes are calculated.
The configuration in the embodiment, the interfaces and functions of its respective parts are as follows:
the keyboard and the mouse adopt a USB2.0 interface chip, are connected with the keyboard and the mouse through a USB port, and acquire data sent by the keyboard and the mouse; and reporting to the keyboard and mouse equipment file of the operating system through UART interface drive. The specific model of the USB2.0 interface chip is FE 2.1.
The keyboard and mouse data acquisition module adopts a USB2.0 interface chip and is responsible for acquiring keyboard and mouse original data and reporting the keyboard and mouse original data to an operating system equipment file through a UART interface, and a program acquires the keyboard and mouse original data through reading the equipment file and sends the data to a computing node through a keyboard and mouse message communication module. The specific model of the USB2.0 interface chip is FE 2.1.
And the keyboard and mouse conversion calculation module is responsible for converting the keyboard and mouse data received from the node or each brother node into keyboard and mouse data on the seat, and then returning the calculated seat keyboard and mouse data to each brother node through the inter-node keyboard and mouse communication module. The keyboard-mouse conversion calculation module is realized based on the mature service logic realized by pure codes in the prior art:
setting seat resolution data (w, h), original mouse position data (delta x, delta y), an initial seat mouse position (0,0), a current seat mouse position (x0, y0), 0 < = x0 < = w,0 < = y0 < = h;
the mouse position on the seat (x0 + -deltax, y0 + -deltay).
The keyboard and mouse message communication module comprises: TCP server and TCP client processing program based on TCP/IP protocol transmission layer and network unit supporting gigabit Ethernet transmission.
