In the invention, the method for converting the mouse data of each seat side node into the mouse data on the seat by the keyboard and mouse data conversion calculation module is as follows:
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).
In the invention, the keyboard and mouse data conversion and calculation module directly transmits the keyboard data of each seat side node without conversion, thus forming the keyboard data on the seat.
In the invention, a plurality of KVM seat side nodes contained in each KVM seat are communicated with each other through a keyboard and mouse data communication module.
Compared with the prior art, the invention has the beneficial effects that:
by adopting the system of the invention, all mouse data information and keyboard key data information on the same seat can be gathered to a key mouse data conversion calculation module of a seat side node for uniform conversion calculation, the calculated key mouse data is distributed to all brother nodes again by the node, each seat node on the seat is ensured to have the same key mouse data after conversion calculation, and each brother node judges whether to make subsequent treatment by the brother node according to the calculated key mouse data, such as: whether the converted keyboard and mouse data are sent to a remote host or an OSD menu by the user. Briefly, data of a plurality of sets of keyboards and mice on a seat are gathered on one seat node through a keyboard and mouse data communication module for unified calculation and then distributed back to each node, each node holds the same keyboard and mouse data after conversion calculation in real time, and each brother node judges whether to be sent to a remote host or an OSD menu by the brother node according to the data
Under the condition that one set of keyboard mouse is inserted, the system of the invention can not cause any influence on the operation of the prior seat when any other sets of keyboard mice are plugged, thereby achieving the standard of plug and play.
The system of the invention enhances the convenience of single-seat user accessing the keyboard and mouse, i.e. the user can access the keyboard and mouse to any seat side node of the seat at will without specifying which set of keyboard and mouse is used, all the configurations are completely processed by software, plug and play are realized, the complexity of the system is reduced, and the distribution of the system is enhanced.

Detailed Description
The technical scheme of the invention is more clearly and completely described in the following with reference to the accompanying drawings and implementation. It should be understood that the embodiments described herein are only for the purpose of illustrating the present invention and are not to be construed as limiting 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 and mouse cooperative control system in a distributed KVM agent 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 data 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.
