Technical Field
The invention relates to the technical field of mouse message transmission, in particular to a multi-mouse cooperative control system in a distributed KVM seat system.
Background
In the existing distributed KVM seat management system, a seat used by a user is only connected with one set of keyboard and mouse. The following disadvantages exist: firstly, when the size of the seat of a user is relatively large, in order to conveniently see the image pictures on other displays under the condition that only one set of key mouse can be operated, the key mouse needs to be inserted into a nearby seat side node, so that the convenience of the operation of the user is greatly influenced, and the working efficiency is greatly influenced; secondly, when a user uses a display supporting touch, the user wants to use a keyboard and a mouse to operate, and the existing KVM system on the market cannot support the touch; third, when two operators are required to cooperatively operate the same seat, one set of keyboard cannot be realized.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a multi-mouse cooperative control system in a distributed KVM seat system. According to the invention, any plurality of sets of key mice or any number of keyboards or mice can be inserted into the same seat of the distributed KVM seat system, the key mice do not need to exist in pairs, plug and play can be realized, and the plug and play process does not cause any influence on the operation of the existing seat.
The technical scheme adopted by the invention is as follows.
A multi-key mouse cooperative control system in a distributed KVM seat system, each KVM seat in the distributed KVM seat system comprises a plurality of KVM seat side nodes, and each KVM seat side node is connected with a keyboard, a mouse or a set of keyboard and mouse; each KVM seat side node comprises a key mouse data acquisition module and a key mouse data communication module; at least one KVM seat side node included in each KVM seat also comprises a keyboard and mouse data conversion calculation module; wherein:
the key mouse data acquisition module is used for acquiring the most original keyboard data and the most original mouse data acquired by the driving layer from the operating system;
the key mouse data communication module is used for sending the keyboard data and the mouse data of the seat side nodes acquired by the key mouse data acquisition module to the key mouse data conversion calculation module and sending the data calculated by the key mouse data conversion calculation module back to the seat nodes;
the keyboard and mouse data conversion calculation module is used for converting the received keyboard data and mouse data of the nodes at the seat side into the keyboard and mouse data on the seat.
In the invention, the method for converting mouse data of nodes at the seat side into mouse data on the seat by the mouse data conversion calculation module is as follows:
setting seat resolution data (w, h), original position data (deltax, deltay) of a mouse, an initial seat mouse position (0, 0), a current seat mouse position (x 0, y 0), 0 < =x0 < =w, 0 < =y0 < =h;
the mouse position (x0±Δx, y0±Δy) on the seat.
In the invention, the keyboard and mouse data conversion calculation module directly transmits the keyboard data of the nodes at the side of each seat without conversion, thus obtaining 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 converged to a key mouse data conversion calculation module of a seat side node to carry out unified conversion calculation, and the node is distributed to brother nodes after calculation, so that each seat node on the seat has the same part of the converted and calculated key mouse data, and each brother node judges whether subsequent processing should be carried out by the brother node according to the calculated key mouse data, for example: whether the converted mouse data is sent to a remote host or sent to an OSD menu by the user. Simply, the data of multiple sets of keyboards and mice on the seat are concentrated to one seat node through the keyboard and mouse data communication module to be uniformly calculated and then are sent back to each node, so that each node holds the same converted and calculated keyboard and mouse data in real time, and each brother node judges whether to send the data to a remote host or an OSD menu or not according to the data
Under the condition that one set of keyboard and mouse is inserted, the system of the invention can not cause any influence on the operation of the existing seat when any other sets of key mice are plugged in and plugged out, thereby reaching the plug-and-play standard.
The system enhances the convenience of single seat users for accessing the keymice, namely, the users can access the keymice to any seat side node of the seat at will without appointing which set of keymice to use, and all configurations are completely processed by software by themselves, so that plug and play is realized, the complexity of the system is reduced, and the distribution of the system is enhanced.

FIG. 1 is a block diagram of a multi-mouse cooperative control system in a distributed KVM seat system.
Detailed Description
The technical scheme of the invention is more clearly and completely described below with reference to the accompanying drawings and implementation. It should be understood that the embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. All other embodiments used by those skilled in the art without the inventive effort are within the scope of the present invention.
FIG. 1 is a block diagram of a multi-mouse cooperative control system in a distributed KVM seat system. As shown in fig. 1, the distributed KVM seat system includes a plurality of seat side nodes S0, S1, S2 … Sn and a plurality of host side nodes H0, H1, H2 … Hn; each KVM seat side node is respectively connected with a set of keyboard and mouse; the KVM host side node is connected with a host; the KVM seat side node and the KVM host side node are respectively connected with the switch; each seat side node comprises a key mouse data acquisition module and a key mouse data communication module; at least one of the agent side nodes comprises a keyboard and mouse data conversion calculation module, one of the agent side 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 the respective parts thereof are as follows:
the keyboard and the mouse adopt a USB2.0 interface chip, and are connected with the keyboard and the mouse through a USB port to acquire data sent by the keyboard and the mouse; and reporting to an operating system through a UART interface driver.
The key mouse data acquisition module is responsible for acquiring the most original key mouse data acquired by the driving layer from the operating system, and transmitting the data to the computing node through the inter-node key mouse data communication module.
The key mouse data conversion calculation module is responsible for converting the received key mouse data from the node or each brother node into key mouse data on the seat, and then the calculated seat key mouse data is returned to each brother node through the inter-node key mouse data communication module.
