[0002] With the rapid development of technology, servers are being used more and more widely, making the management and control of a large number of local servers a very important issue. Remote control refers to connecting a local computer via a local area network or the Internet, displaying the local computer's desktop environment on a remote computer, and enabling remote configuration, monitoring, software maintenance, upgrades, and troubleshooting of the local computer, thus realizing server management.

[0003] In remote control systems, KVM (Keyboard Video Mouse) enables a single terminal to access and control multiple computers. KVM devices, by directly connecting to keyboard, video, and mouse ports, allow administrators to access and control multiple computers from a single terminal. Remote mouse and keyboard operations enable control of the local server. Traditional mouse and keyboard information processing involves encoding the information from the remote end and transmitting it over the network to the local machine. The local driver software then receives and parses this information via the USB (Universal Serial Bus) system, transmitting it to the operating system or application to process the corresponding mouse and keyboard events. In this process, the driver software repeatedly acquires and parses the same mouse and keyboard information, wasting resources and bus bandwidth.

[0010] The present invention also provides a remote transmission device for mouse and keyboard information, comprising: The acquisition unit is used to acquire the encoding result corresponding to the mouse and keyboard information currently transmitted to the local machine in response to the interrupted transmission polling request. The first signal unit is used to generate a mouse and keyboard stillness indication signal when the encoding result is the same as the historical encoding result corresponding to the historical mouse and keyboard information, and send the mouse and keyboard stillness indication signal to the USB HOST module so that the USB HOST module suspends the interrupted transmission polling of the mouse and keyboard information. The second signal unit is used to generate a mouse and keyboard action indication signal when the encoded result is different from the historical encoded result corresponding to the historical mouse and keyboard information, and send the mouse and keyboard action indication signal to the USB HOST module so that the USB HOST module restarts the interrupted transmission polling of the mouse and keyboard information.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] like Figure 5 As shown, Figure 5 This is a schematic diagram of the application environment provided by the present invention. The remote end refers to the user end, including a mouse and keyboard, which can collect mouse and keyboard information remotely. Specifically, during the collection process, the mouse collects mouse action information through sensors, including mouse position, movement speed, click actions, etc.; the keyboard receives input key information. The collected mouse and keyboard information is encoded and converted into corresponding digital codes.

[0027] The local server management system processes information locally. The network module receives mouse and keyboard data transmitted to the local machine via Ethernet and stores the collected information in DDR (Double Data Rate Synchronous Dynamic Random Access Memory).

[0028] The USB system receives mouse and keyboard information from a remote location. The USB DEVICE module communicates with the USB HOST module to transmit signals and data. During actual transmission, the USB HOST module actively initiates requests to the USB DEVICE module, and the USB DEVICE module responds accordingly. For the transmission of mouse and keyboard information, the USB system uses interrupt transmission. The USB HOST module polls the USB DEVICE module and initiates requests at fixed time intervals, and the USB DEVICE module responds with the mouse and keyboard information data for the current moment.

[0029] When the USB DEVICE module detects no mouse or keyboard activity on the user's end, it sets the mouse / keyboard inactivity indicator signal and transmits it to the USB HOST module. Upon receiving the inactivity indicator signal, the USB HOST module interrupts transmission and enters sleep mode, pausing polling of the USB DEVICE module until it receives a mouse / keyboard activity indicator signal, at which point it resumes interrupted transmission polling of the USB DEVICE. The mouse / keyboard activity indicator signal is set and transmitted to the USB HOST module by the USB DEVICE module when it detects mouse or keyboard activity on the user's end.

[0030] The following is combined with Figure 1 This invention describes a method for remotely transmitting mouse and keyboard information, applicable to USBDEVICE modules. Figure 1 This is a flowchart illustrating the remote transmission method for mouse and keyboard information provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps: Step 110: In response to the interruption transmission polling request, obtain the encoding result corresponding to the mouse and keyboard information currently transmitted to the local machine.

[0031] It should be noted that the encoded result of the mouse and keyboard information currently transmitted to the local device is obtained by the USB DEVICE module from the DDR.

[0032] Step 120: If the encoded result is the same as the historical encoded result corresponding to the historical mouse and keyboard information, generate a mouse and keyboard stillness indication signal and send the mouse and keyboard stillness indication signal to the USB HOST module so that the USB HOST module suspends the interrupted transmission polling of the mouse and keyboard information.

[0033] After obtaining the encoding result in step 110, the received current encoding result is compared with the historical encoding result corresponding to the historical mouse and keyboard information, and processed and analyzed. When the encoding result is the same as the historical encoding result corresponding to the historical mouse and keyboard information, that is, when the received mouse and keyboard information is the same as the previously received mouse and keyboard information, a mouse and keyboard stillness indication signal is issued and transmitted to the USB HOST module. The USB HOST module can pause the interrupted polling of the mouse and keyboard information transmission based on the mouse and keyboard stillness indication signal.

[0034] Step 130: If the encoded result is different from the historical encoded result corresponding to the historical mouse and keyboard information, generate a mouse and keyboard action indication signal and send the mouse and keyboard action indication signal to the USB HOST module so that the USB HOST module restarts the interrupted transmission polling of the mouse and keyboard information.

[0035] After obtaining the encoding result in step 110, the received current encoding result is compared with the historical encoding result corresponding to the historical mouse and keyboard information, and processed and analyzed. When the encoding result is different from the historical encoding result corresponding to the historical mouse and keyboard information, that is, the received mouse and keyboard information is different from the previously received mouse and keyboard information, a mouse and keyboard action indication signal is issued and transmitted to the USB HOST module. The USB HOST module can restart the interrupted polling of the mouse and keyboard information transmission based on the mouse and keyboard action indication signal.

[0036] The following further explains how the USB DEVICE module retrieves the encoded result corresponding to the mouse and keyboard information currently transmitted to the local machine from the DDR. In some embodiments, retrieving the encoded result corresponding to the mouse and keyboard information currently transmitted to the local machine specifically includes: Capture the encoded results of mouse and keyboard information in DDR based on the AHB bus protocol; The mouse and keyboard information includes the mouse position, mouse movement speed, mouse click action, and key input information received by the keyboard. The encoding result corresponding to the mouse and keyboard information in the DDR is obtained by acquiring the user's mouse and keyboard information via Ethernet, encoding the mouse and keyboard information, and then storing the encoding result in the DDR based on the AXI bus protocol.

[0037] Specifically, in the actual process, the user's mouse collects mouse action information through sensors, including mouse position, movement speed, and click actions; the keyboard receives input keystrokes. The collected mouse and keyboard information is encoded and converted into corresponding digital codes to obtain the encoded result.

[0038] The mouse and keyboard information, along with their corresponding encoding results, are then transmitted from the remote location to the local location via Ethernet. The local network module, based on the AXI bus protocol, stores the mouse and keyboard information and their corresponding encoding results in DDR memory. The USB device module then captures the mouse and keyboard information and their corresponding encoding results from the DDR memory using the AHB bus protocol.

[0039] Furthermore, the USB DEVICE module will be explained in more detail. For example... Figure 4 As shown, within the USB DEVICE module, the USB DEVICE control module controls the USB device based on the USB specification; the capture module captures mouse and keyboard information and / or mouse and keyboard information and their encoding results stored in DDR via the AHB bus, and then stores the mouse and keyboard information and / or mouse and keyboard information and their encoding results in the buffer of the USB DEVICE module; the comparison module compares the currently received mouse and keyboard information with the previously received mouse and keyboard information. When the currently received mouse and keyboard information is the same as the previously received mouse and keyboard information, it indicates that the remote mouse and keyboard is not active, and the mouse and keyboard inactive signal is pulled high; when the currently received mouse and keyboard information is different from the previously received mouse and keyboard information, it indicates that the remote mouse and keyboard is active, and the mouse and keyboard active signal is pulled high; the data buffer module stores the captured mouse and keyboard information.

[0040] The following is combined with Figure 2 Another method for remote transmission of mouse and keyboard information according to the present invention is described, which is applicable to a USBHOST module. Figure 2 This is a flowchart illustrating another method for remote transmission of mouse and keyboard information provided by the present invention, as shown below. Figure 2 As shown, the method includes the following steps: Step 210: In response to receiving the mouse and keyboard stillness indication signal, pause the interrupted transmission polling of mouse and keyboard information; the mouse and keyboard stillness indication signal is generated by the USB DEVICE module when the current mouse and keyboard information is the same as the historical mouse and keyboard information.

[0041] Specifically, because the USB HOST module polls the USB DEVICE module during the set time interval, the driver software parses the mouse and keyboard information and passes it to the operating system or application. After the USB HOST module receives the mouse and keyboard stillness indication signal, it pauses the interruption of the mouse and keyboard information polling until it receives the mouse and keyboard action indication signal.

[0042] The mouse and keyboard stillness indicator signal is generated when the currently captured mouse and keyboard information is the same as the previously captured mouse and keyboard information. For the specific generation method, please refer to the above embodiment. This invention will not elaborate on this.

[0043] Step 220: In response to receiving the mouse and keyboard action indication signal, restart the interrupted transmission polling of mouse and keyboard information; the mouse and keyboard action indication signal is generated by the USB DEVICE module when the current mouse and keyboard information is different from the historical mouse and keyboard information.

[0044] After the USB HOST module receives the mouse and keyboard action indication signal, it restarts the interrupted polling of mouse and keyboard information transmission.

[0045] The mouse and keyboard action indication signal is generated when the currently captured mouse and keyboard information is different from the previously captured mouse and keyboard information. For the specific generation method, please refer to the above embodiment. This invention will not elaborate on this.

[0046] Furthermore, in response to receiving a mouse and keyboard action indication signal, the process restarts the interrupted polling of mouse and keyboard information transmission, and then includes: Send an interrupt transmission polling request to the USB DEVICE module.

[0047] Based on the above embodiments, such as Figure 3 As shown, the following is a specific embodiment of a USB DEVICE module and a USB HOST module interacting to remotely transmit mouse and keyboard information, including steps S1-S10: S1: Mouse and keyboard information acquisition. The mouse collects mouse action information, including mouse position, movement speed, and click actions, through sensors or sensors; the keyboard receives input key presses. The acquired mouse and keyboard information is encoded and converted into corresponding digital codes.

[0048] S2: The encoded information of the mouse and keyboard is transmitted from the remote end to the local end via Ethernet.

[0049] S3: The local network module is based on the AXI bus protocol and stores mouse and keyboard information in DDR.

[0050] S4: The capture module in the USB DEVICE module captures mouse and keyboard information from DDR based on the AHB bus protocol.

[0051] S5: The comparison module in the USB DEVICE module compares the currently captured mouse and keyboard information with the previously captured mouse and keyboard information.

[0052] S6: If the currently captured mouse and keyboard information is different from the previously captured mouse and keyboard information, it indicates that mouse and keyboard actions have occurred, and the mouse and keyboard action indication signal is set.

[0053] S7: The USB HOST module polls the USB DEVICE module at set time intervals, and the driver software parses mouse and keyboard information and passes it to the operating system or application.

[0054] S8: Increment the mouse and keyboard information count by one, then proceed to step S1.

[0055] S9: If the currently captured mouse and keyboard information is the same as the previously captured mouse and keyboard information, it indicates that no mouse or keyboard action has occurred, and the mouse and keyboard stationary indicator signal is set.

[0056] S10: After receiving the mouse and keyboard stillness indicator signal, the USB HOST module interrupts the polling and enters sleep mode, stops the interrupt transmission polling of the USB DEVICE module, and proceeds to step S8.

[0057] The mouse and keyboard information remote transmission method provided by this invention acquires the encoded results of mouse and keyboard information transmitted to the local device via a USB DEVICE module, and processes and analyzes the current and historical encoded results. When the received current and historical encoded results are the same, a mouse and keyboard stationary indicator signal is issued; when the received current and historical encoded results are different, a mouse and keyboard action indicator signal is issued. This indicator signal is transmitted to a USBHOST module. Upon receiving the mouse and keyboard stationary indicator signal, the USB HOST module pauses its interrupted polling of mouse and keyboard information transmission until it receives the mouse and keyboard action indicator signal, at which point it resumes the interrupted polling of mouse and keyboard information transmission. This invention avoids the repeated acquisition and parsing of the same mouse and keyboard information by the driver software, saving resources and bus bandwidth.

The second signal unit 630 is used to generate a mouse and keyboard action indication signal when the encoded result is different from the historical encoded result corresponding to the historical mouse and keyboard information, and send the mouse and keyboard action indication signal to the USB HOST module so that the USB HOST module restarts the interrupted transmission polling of the mouse and keyboard information.

The restart unit 720 is used to restart the interrupted transmission polling of mouse and keyboard information in response to receiving a mouse and keyboard action indication signal; the mouse and keyboard action indication signal is generated by the USB DEVICE module when the current mouse and keyboard information is different from the historical mouse and keyboard information.
