Detailed Description
The invention is described in further detail below with reference to specific embodiments.
The computer data transmission system as shown in FIG. 1 includes two computers (hosts) and a KVM switch. As shown in fig. 2, the KVM switch includes a switch control module connected to the computer 1 in fig. 1 through a communication interface 1 and connected to the computer 2 in fig. 1 through a communication interface 2, and two communication interfaces. The computer data transmission system comprises a mouse, a keyboard and a display as shown in figure 1. As shown in FIG. 2, the KVM switch includes a mouse input interface, a keyboard input interface and a display output interface as input/output interfaces. The switching control module is respectively connected with the mouse, the keyboard and the display through a mouse input interface, a keyboard input interface and a display output interface. In an initial state, the switching control module enables the mouse input interface, the keyboard input interface and the display output interface to be communicated with the communication interface 1, so that a user can operate the computer 1 through the mouse, the keyboard and the display.
The computer 1 and the computer 2 each include a processor and a computer-readable storage medium in which an executable computer program is stored, the processor executing the computer program to realize a data transmission method of the computer, and the flow of the method is described below by way of example:
as shown in fig. 2, the KVM switch includes a relay register module, and the two communication interfaces are respectively configured with data lines to connect to the relay register module. If a user needs to send data of the computer 1 to the computer 2, in the initial state, the user inputs a data sending command to the computer 1 through the mouse, after receiving the command, the computer 1 encrypts local data requested to be sent by the user through a cryptographic algorithm, and then sends the encrypted data to a transfer temporary storage module of the KVM switch through the communication interface 1 for temporary storage. The KVM switcher is provided with a switch, and after the data are sent to the transfer temporary storage module, a user inputs a switching signal to the switching control module through the switch. After receiving the switching signal, the switching control module switches the mouse input interface, the keyboard input interface and the display output interface to the communication interface 2, that is, the signal ends of the mouse, the keyboard and the display are switched to the communication interface 2, so that a user can operate the computer 2 through the mouse, the keyboard and the display. After switching to the communication interface 2, the user can input a data pull command to the computer 2 through the mouse. After receiving the command, the computer 2 pulls the encrypted data from the transfer temporary storage module of the KVM switch to the local computer 2, deletes the encrypted data in the transfer temporary storage module after the pulling is completed, and then decrypts the data. The user can then process the data on the computer 2 via the mouse, keyboard and display.
On the contrary, if the user wants to send the data of the computer 2 to the computer 1, the switching signal is input to the switching control module through the switch in the initial state. After receiving the switching signal, the switching control module switches the mouse input interface, the keyboard input interface and the display output interface to the communication interface 2, after switching to the communication interface 2, the user can input a data transmission command to the computer 2 through the mouse, after receiving the command, the computer 2 encrypts local data requested to be transmitted by the user through a cryptographic algorithm, and then transmits the encrypted data to the transfer temporary storage module of the KVM switch for temporary storage through the communication interface 2. After the data is sent to the transfer temporary storage module, the user inputs a switching signal to the switching control module through the switch to switch the mouse input interface, the keyboard input interface and the display interface to the communication interface 1 again. The user can then enter a data pull command into the computer 1 via the mouse. After receiving the command, the computer 1 pulls the encrypted data from the transfer temporary storage module of the KVM switch to the local computer 1, deletes the encrypted data in the transfer temporary storage module after the pulling is completed, and then decrypts the data.
As shown in fig. 2, the KVM switch further includes a USB interface connected to the switching control module, and the switching control module switches the USB interface to communicate with the same communication interface together with the mouse input interface, the keyboard input interface, and the display output interface. If a user needs to print a file in the computer 1 or the computer 2, the user can connect the printer to the USB interface. For example, when a user wants to print a file in the computer 1, the mouse input interface, the keyboard input interface, the display output interface, and the USB interface are switched to the communication interface 1, and then the computer 1 is operated by the mouse to transmit the file in the computer 1 to the printer for printing. Similarly, if the user needs to print the file in the computer 2, the mouse input interface, the keyboard input interface, the display output interface and the USB interface are switched to the communication interface 2, and then the computer 1 is operated by the mouse to send the file in the computer 2 to the printer for printing. In other embodiments, the USB interface may be changed to connect to other external devices.
As shown in fig. 2, the KVM switch includes a network interface and two network link interfaces 1 and 2, the network interface is connected to the external network through a network cable, and the two network link interfaces 1 and 2 are respectively connected to the computer 1 and the computer 2 through the network cable. In the initial state, the network interface communicates with the network link interface 1. In this embodiment, the network interface is synchronously switched with the mouse input interface, the keyboard input interface and the display output interface, and the switching control module switches the mouse input interface, the keyboard input interface and the display output interface to the communication interface 2 and also switches the network interface to the communication network link interface 2; when the mouse input interface, the keyboard input interface and the display output interface are switched to the communication interface 1, the network interface is also switched to the communication network link interface 1. Non-preferably, the network interface and the mouse input interface, the keyboard input interface and the display output interface are switched separately, and the user needs to input a network link interface switching signal to switch the network interface to the connected target network link interface and additionally input a communication interface switching signal to switch the mouse input interface, the keyboard input interface and the display output interface to the connected target communication interface.
The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which fall within the scope of the claims.
