It can be clearly understood by those skilled in the art that, for convenience and brevity of description, the specific working process and related description of the system described above may refer to the corresponding process in the foregoing method embodiments, and will not be described herein again.
It should be noted that, the multi-specification display screen layout system of the KVM system provided in the foregoing embodiment is only illustrated by the division of the above functional modules, and in practical applications, the above functions may be distributed by different functional modules according to needs, that is, the modules or steps in the embodiment of the present invention are further decomposed or combined, for example, the modules in the foregoing embodiment may be combined into one module, or may be further split into multiple sub-modules, so as to complete all or part of the above described functions. The names of the modules and steps involved in the embodiments of the present invention are only for distinguishing the modules or steps, and are not to be construed as unduly limiting the present invention.
As shown in fig. 3, the KVM system multi-specification display layout method according to the second embodiment of the present invention is based on the above KVM system multi-specification display layout system, and the method includes:
and step B10, generating each display screen model with corresponding size based on the acquired display screen parameters.
B20, controlling the display screen models to move on the display interface through a mouse, and adjusting the screen positions of the display screen models; and calling screen attributes through a mouse or a keyboard, and setting a screen picture segmentation mode.
And step B30, generating the minimum circumscribed rectangle of each display screen based on the screen position of each display screen and the set screen picture segmentation mode, and generating a seat coordinate system with the upper left corner of the minimum circumscribed rectangle as the origin.
At present, none of KVM switches or seat systems in the market considers that a display device of a user is placed at will, has any size and has any resolution, and most of existing systems specify the number of rows and columns to generate corresponding seat data. In order to solve the problem, the agent layout mode of the invention can enable a user to freely define the size and resolution information of the display, the display position can be dragged to any position by the user, and the division mode in the screen can be defined by the user. The system generates a maximum external rectangle according to the placing position of the user display, and the maximum external rectangle is used as a coordinate system of the whole seat. Each screen generates corresponding position coordinates according to the overall coordinate system. When the mouse moves in the whole seat, the current resolution of the screen and the physical size of the screen are converted into the corresponding position of the mouse in the whole large seat, so that the roaming processing of the mouse in the irregular display screen seat system is realized.
As shown in fig. 3, the size, the division mode and the resolution information of the display screen may be different, and the overall placement position may be placed by the user himself, and the position where the display screen is connected in fig. 3 is a mouse-passing position.

step S30, respectively calculating the current position of the seat and the display screen of the new position of the seat based on the parameters of the display screens, judging whether the display screen of the new position of the seat is effective or not, and if not, skipping to the step S20; if the current position of the seat and the new position of the seat are valid, respectively calculating the current position coordinates and the new position coordinates of the seat in the corresponding display screen;
step S40, according to the acquired screen segmentation information and the associated computer information, acquiring a computer C1 corresponding to the current position of the seat and a computer C2 corresponding to the new position of the seat, and calculating the coordinate of the new position of the seat in the computer C2;
step S50, judging whether the computer C1 and the computer C2 are the same computer, if not, sending a command of hiding the mouse and being inactive to the computer C1; if yes, setting the computer C2 as a current active computer, and sending the coordinates of the new seat position in the computer C2 to the computer C2;
step S60, the current seat coordinates are updated to new position coordinates, and the process goes to step S20.
