The technical scheme of the present invention is described in detail below in conjunction with the drawings and specific embodiments, so as to further understand the purpose, scheme and effect of the present invention, but it is not intended to limit the scope of the appended claims of the present invention.

Please refer to FIG. 1 , which is an architecture diagram of a remote monitoring system. The remote monitoring system is provided with a BMC 104 (Baseboard Management Controller) in the local computer 10 .

The BMC 104 is connected to the network module 102 and is used to implement out-of-band (Out-Of-Band) management of the local computer 10. For example, the remote computer 12 can control the local computer 10 to switch on and off, obtain peripherals through the network 11 and the BMC 104. Status information of the device 103 or the chip set 101 , to control the peripheral device 103 or the chip set 101 , etc.

However, under the structure of the remote monitoring system, due to the permission problem, the BMC 104 cannot directly obtain the video signal (ie, the display screen of the local display 105 ) generated by the processor 100 , and cannot realize the remote mirror display, that is, it cannot The remote computer 12 mirrors and displays the display screen of the local display 105 . In addition, the BMC 104 can also be connected to another local display 106 and display information through the local display 106 .

Please refer to FIG. 2 , which is a schematic diagram of another remote control system. This remote control system adopts Intel® Active Management Technology (AMT, Intel Active Management Technology) to realize remote mirror display.

Specifically, in the local computer 13 , the processor 130 is provided with an AMT 133 , and the chipset 131 is provided with an AMT 134 . The AMT 133 of the processor 130 can transmit the display image (video signal) to the local display 132 for display, and transmit the same display image to the AMT 134 of the chipset 131, and then through the chip The chip set 131 (connected to the aforementioned network module 102 ) is transmitted to the remote computer 12 through the network 11 to display the mirror image of the local display 132 on the remote display 14 , thereby realizing the remote mirror display.

However, at present, only Intel® high-end processors have AMT function, and they must be equipped with specified Intel® chips, which makes the cost of remote mirror display too high, that is, greatly increases the hardware cost and greatly reduces the hardware configuration. degrees of freedom. Moreover, the aforementioned AMTs 133 and 134 are like black boxes, and ordinary people cannot know their specific structures, and cannot modify or customize them.

In order to solve the above problems, the present invention provides a computer system with a remote monitoring function, a remote monitoring system and a remote monitoring method, which can realize Out-Of-Band management and remote mirror display. as follows.

Please also refer to FIG. 3 , which is a structural diagram of a computer system according to an embodiment of the present invention.

The processor 20 (eg, CPU) is used for the main operations and control. The chipset 21 is electrically connected to the processor 20 and other devices (eg, the network module 21 or the peripheral device 24 described later), and is controlled by the processor 20 to drive other devices. The network module 22 (such as an Ethernet network card, a Wi-Fi network card, a cellular network module or other network modules with networking capability) is used to connect to the network 40 (such as the Internet), It can communicate with the remote computer 41 through the network 40 . The local display 23 (eg, touch screen, LCD screen, projector, plasma screen or other types of displays) is used to display information.

The remote monitoring system 3 is mainly used to provide the local display image of the local computer 2 (ie the display image of the local monitor 23 ) to the remote computer 41 (such as desktop computer, notebook computer, workstation, server, etc.) in real time for remote real-time display.

Specifically, the remote monitoring system 3 includes a signal receiver 30 and a remote controller 31 . The signal receiver 30 (which can be obtained by modifying existing display adapters) is directly connected to the processor 20, and the video signal corresponding to the local display screen can be directly received from the processor 20. The remote controller 31 (which can be obtained by modifying the existing BMC or single-chip controller) is used to transmit the video signal to the remote computer 41 for remote mirror display.

Specifically, please refer to FIG. 9 , which is a flowchart of a remote monitoring method according to an embodiment of the present invention.

In this embodiment, when the local computer 2 is operating (eg, after the startup is completed), the processor 20 continues to transmit the video signal V1 to the local display 23 to display the local display image on the local display 23 .

In addition, when the remote mirror display is started, step S10 is executed, the processor 20 provides a video signal of the first standard (the first video signal S1, such as the DisplayPort standard or other output standard supported by the processor 20 ), and the signal receiver 30 The first video signal S1 is continuously received from the processor 20 .

Next, step S11 is executed. Since the remote controller 31 usually does not support the output standard (the first standard) of the processor 20, in the present invention, the signal receiver 30 performs signal conversion processing (eg, video standard conversion) on the first video signal S1. ) to convert the first video signal S1 from the first standard to the input standard supported by the remote controller 31 (the second standard, such as HDMI standard, VGA standard, DVI standard, TTL standard, LVDS standard, CVBS standard, S-Video standard or YPbPr standard) to obtain the second video signal S2 different from the first standard.

Next, step S12 is executed, the signal receiver 30 transmits the second video signal S2 to the remote controller 31 .

Next, step S13 is executed. The general video standard cannot be directly used for network transmission. In the present invention, the remote controller 31 performs network compression (eg, converts it into a streaming video) to the second video signal S2 to generate a Video data S3 of network transmission standard (such as Live Streaming Protocol).

Finally, step S14 is executed, the remote controller 31 transmits the generated video data S3 to the network module 22, and the network module 22 converts the video data S3 into video data S4 (such as data packets) that can be transmitted over the network, and It is transmitted to the remote computer 41 through the network 40 . The remote computer 41 can execute the received video data S4. The video signal V2 is obtained through line decoding processing (including decapsulation, video standard conversion, etc.), and sent to the remote display 42 to display the remote display corresponding to the local display on the remote display 42 .

In one embodiment, the local display image and the remote display image are mirror images, that is, the two have the same layout and display content, but are allowed to have different display parameters, such as resolution or aspect ratio.

In one embodiment, the remote display screen may include a display window, the display window is used to display the received local display screen, and other display areas of the remote display screen can still be used to perform operations on the remote computer 41 or The information of the remote computer 41 is displayed.

DDI technology has been widely used in computer systems, it mainly allows the processor 20 to directly output video signals to other devices (in this example, the display adapters 510-512 and the signal receivers) without going through the main memory (RAM). 30) to achieve high-speed transmission.

In this example, the processor 20 has four video signal ports 500-503 (such as DisplayPort signal output ports, the number of video signal ports can be arbitrarily modified), and each video signal port 500-503 is used to output the video of the first standard mentioned above. signal.

The video signal ports 500-502 are respectively connected to display adapters 510-512, and the display adapters 510-512 are respectively connected to corresponding display connectors 520-522. Adapt to each display The connectors 510-512 are used to convert the video signal of the first standard to the video standard supported by the display connectors 520-522.

For example, the display adapter 512 can convert the video signal from the DisplayPort standard to the HDMI standard, transmit the video signal of the HDMI standard to the display connector 522 (eg, the HDMI connector), and transmit the video signal of the HDMI standard through the display connector 522 to the display connector 522. The local display 23 displays.

In the present invention, a video signal port 503 of the processor 20 is connected to the signal receiver 30, and the video signal ports 502 and 503 are set to the mirror display mode (that is, the video signals transmitted in the video signal ports 502 and 503) The signal is the same), so that the signal receiver 30 can directly receive the mirrored video signal from the processor 20 through the DDI 53, and provide the video signal to the remote computer 41 for display after converting the standard of the video signal.

Please also refer to FIG. 5 , which is a structural diagram of a video element according to an embodiment of the present invention. In the example of FIG. 5 , the remote monitoring system may include a high-speed hub 6 . The high-speed hub 6 may have one or more inputs and multiple outputs.

When the display connector 522 and the remote controller 31 support the same video standard (such as HDMI standard or VGA standard), the present invention can directly connect the single video signal port 502 to the local display 23 and the remote controller 31, However, the above-mentioned related settings of the mirror display mode can be omitted.

Specifically, the present invention can connect the video signal port 502 to the signal receiver 30, connect an input end of the high-speed hub 6 to the signal receiver 30, and connect the two output ends of the high-speed hub 6 to the display connector 522 (connected to Local display 23) and remote controller 31. Thereby, the first video signal of the first standard provided by the processor 20 through the video signal port 502 is converted into the second video signal of the second standard (such as HDMI standard or VGA standard) through the signal receiver 30, and the second video signal is input to the input After the high-speed hub 6 is broadcasted to the display connector 522 and the remote controller 31 , the local display image is displayed on the local display 22 , and the mirrored remote display image is displayed on the remote display 42 .

Please refer to FIG. 6 and FIG. 10 together. FIG. 6 is a structural diagram of a computer system according to an embodiment of the present invention, and FIG. 10 is a structural diagram and a flowchart of a remote monitoring method according to an embodiment of the present invention.

In this embodiment, the local computer 2 may include peripheral devices 24 (eg, a cooling fan device, a power supply, a hard disk, a keyboard, a mouse, etc.). The peripheral device 24 is connected to the chipset 21 to receive local monitoring, and can also be connected to a remote controller 31 (not shown) to receive remote monitoring. The remote controller 31 connects the chipset 21 and the processor 20 .

The remote monitoring system may include a BIOS (Basic Input/Output System, Basic Input/Output System) 32 . The BIOS 32 is installed in the local computer 2 (eg, installed in the EEPROM), and is used to be loaded and executed after the local computer 2 is started, so as to realize the hardware initialization of the local computer 2 .

In one embodiment, when the local computer 2 loads and executes the BIOS 32, the BIOS 32 can connect the first video signal port (the video signal port 502 in FIG. 4 ) and the second video signal port (as shown in FIG. 4 ) of the processor 20 The video signal port 503) of 4 is set to mirror mode, so that the two video signal ports transmit the same first video signal.

The execution flow of the remote monitoring method in this embodiment is as follows.

In step S200 , the processor 20 continues to transmit the video signal of the local display screen to the local display 23 for display after being activated.

When performing the remote mirror display, in step S201 , the remote user can send a remote switching request to the remote controller 31 through the network 40 through the input device 43 of the remote computer 41 . The aforementioned remote switching request may include login information (eg, account number, password, IP address of the remote computer 41 , MAC address, or any combination of other verifiable information).

In step S202 , after receiving the remote handover request, the remote controller 31 can perform verification based on the login data of the remote handover request (for example, whether it matches the preset registration data).

In one embodiment, the remote computer 41 can also send operation commands or query requests of the peripheral device 24 to the remote controller 31, and the remote controller 31 can perform corresponding operations (including direct control or through the chipset 21 ), such as controlling the peripheral device 24 according to an operation command, or returning status information as described in step S210 ).

For example, the operation command may be a mouse operation or a keyboard operation of the remote end to the local end, and the remote computer 41 controls the mouse or keyboard of the local end to perform corresponding operations according to the control request.

In step S203 , the remote controller 31 transmits an open display notification to the signal receiver 30 after the remote handover request is verified.

In step S204 , the signal receiver 30 can be connected to the chip set 21 (eg, a pin of a GPIO), and send a notification to display the display to the chip set 21 .

In step S205 , the chipset 21 notifies the processor 20 to enable the connection to the video signal port of the signal receiver 30 (eg, the video signal port 503 in FIG. 4 ).

In step S206 , the processor 20 starts to transmit the first video signal corresponding to the local display image to the signal receiver 30 .

In step S207 , the signal receiver 30 converts the first video signal into a second video signal supported by the remote controller 31 .

In step S208 , the signal receiver 30 inputs the second video signal to the remote controller 31 .

In step S209, the remote controller 31 converts the second video signal into video data that can be transmitted over the network.

In an embodiment, in step S210, the remote controller 31 can obtain the components of the local computer (such as the peripheral device 24, the network module 22, the device connected to the chipset 21, etc.) through the chipset 21 (or directly connected). status information, and send the obtained status information to the remote computer 41 .

In step S211 , the remote controller 31 transmits the video data to the remote computer 41 through the network module 22 , and the remote computer 41 processes the video data and starts to display on the remote display 42 the remote mirror mirrored with the local display screen. Display the screen.

In this way, the present invention enables the remote display 42 to be switched to display the local display screen, and enables the remote input device 43 to control the local computer 2, thereby realizing the remote KVM switch function.

It is worth mentioning that, during the execution of the remote mirror display, the present invention can also provide a refresh function and a disconnection control function of the display screen.

Specifically, please refer to FIG. 11 , which is a partial flowchart of a remote monitoring method according to an embodiment of the present invention.

In step S30, at least one of the signal receiver 30, the remote controller 31 and the processor 20 continuously detects a preset refresh condition (such as a local display screen change or a preset time interval) during the execution of the remote mirror display. , such as 1/30 second) is satisfied.

Step S31 , when the signal receiver 30 (and the remote controller 31 ) monitors that the preset refresh condition is satisfied, the aforementioned steps S10 - S14 (or steps S206 - S211 ) are executed again to obtain a corresponding new local display image from the processor 20 the new first video signal, perform signal conversion processing on the new first video signal to generate a new second video signal, perform network compression processing on the new second video signal to generate new video data, and pass the network The channel module 22 transmits new video data to the remote computer 41 so that the remote display 42 refreshes and displays a new remote display image corresponding to the new local display image.

Thereby, the present invention can realize the refresh function of the remote display screen.

In step S32, at least one of the signal receiver 30 and the remote controller 31 detects whether the remote control is terminated, for example, the remote user disconnects the connection or the connection times out.

In step S32, when the end of the remote control is detected, the remote controller 31 sends a removal display notification to the chip set 21 through the signal receiver 30, and the chip set 21 notifies the processor 20 to stop providing the first video signal to the signal receiver 31, and the provision of the mirrored display screen is discontinued.

It is worth mentioning that when the remote mirror display is started, the processor 20 will set the video signal port 503 ( FIG. 4 ) connected to the signal receiver 30 as the connected display (that is, the local user can connect to the local computer 2 ). It can be seen that the local computer is connected to two monitors, one of which is the local monitor 23 and the other is the remote monitor 42).

If the connection between the remote controller 31 and the remote computer 41 is directly interrupted without changing the above settings of the video signal port 503, even if the remote control is terminated, the local user will still see the local computer on the local computer 2. The computer is connected to two monitors, causing confusion.

In this regard, the present invention notifies the processor 20 to stop providing video signals to the signal receiver 31 through the chipset 21 after the remote control is ended, so that the processor 20 can automatically receive the corresponding connection signal after the end of the remote mirror display. The video signal port 503 (FIG. 4) of the device 30 is set as the monitor removed (that is, the local user can see on the local computer 2 that only one local monitor 23 is connected to the local computer), so as to avoid confusion for the local user and improve the user experience.

In one embodiment, the signal processing module 300 is connected to a group of pins 210 (eg, GPIO pins) of the chip set 21 , and transmits signals through the chip set 21 and the hot-plug controller 200 of the processor 20 . With the above structure, the signal processing module 300 can control the processor 20 to change the state of the video signal port 503 ( FIG. 4 ), such as setting the monitor to connect or remove the monitor, or control the processor 20 to start/stop providing the first video signal .

Please refer to FIG. 8 , which is a structural diagram of a remote controller according to an embodiment of the present invention. In this embodiment, the remote controller 31 may include a signal input module 311 , a network processing module 312 , a connection module 313 , a storage module 314 and a control module 310 electrically connected to the above components.
