[0024] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0026] Currently, the VGA interface is only used for video signal transmission, and its reserved pins (such as Pin4 / 11 / 12 / 15) have been idle for a long time, resulting in a large amount of resource waste. However, this application constructs a target bus based on the pins of the video graphics array interface used to transmit video signals, so that the target bus can be used to transmit data signals other than video signals through the video graphics array interface, which can save a lot of operation and maintenance time.

[0027] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The embodiment of the present application provides a device operation and maintenance method, which is described in detail below in conjunction with the execution process of the device operation and maintenance method. Figure 1 As shown, the above-mentioned equipment operation and maintenance method includes:

[0029] Step S11: Use the target bus to send a pairing request to the target device to be operated and maintained through the video graphics array interface, so that the target device to be operated and maintained performs a pairing operation with the operation and maintenance device according to the pairing request; the target bus is a bus constructed based on the preset pins of the video graphics array interface, and the preset pins are the pins in the video graphics array interface used to transmit video signals.

[0030] First of all, it should be pointed out that this embodiment can be based on Figure 2 The system shown implements device operation and maintenance. The motherboard (MB) serves as a computing node, hosting the CPU (Central Processing Unit) and memory. The baseboard management controller (BMC) collects sensor information, such as temperature, through the MB's complex programmable logic device (CPLD). The motherboard CPLD transmits this information to the management board's field-programmable gate array (FPGA1). In turn, the management board's FPGA1 is connected to the motherboard's BMC, transmitting real-time operation and maintenance information such as VGA signals and server one-key logs.

[0031] Therefore, in this embodiment, the first video graphics array interface of the operation and maintenance device (the device corresponding to the user board) and the second video graphics array interface of the target device to be operated and maintained (the device corresponding to the control board) are connected via a target bus (i.e., a serial peripheral interface (SPI)). It should be noted that in this embodiment, the operation and maintenance device is connected to the control board, utilizing the reserved VGA interface pins 4 (SPI_CLK), 11 (SPI_MOSI), 12 (SPI_MISO), and 15 (SPI_CS#) to construct a four-wire SPI bus, enabling communication between the control board's FPGA1 and the operation and maintenance board's FPGA2. The operation and maintenance device's functions are primarily implemented by two chips: FPGA2 is dedicated to high-speed signal processing (SPI bus communication, VGA parsing, and FLASH (flash memory) programming), while the other chip utilizes an ARM (Advanced RISC Machines) core to run the Linux system, drive USB (Universal Serial Bus) devices, manage display logic, and perform human-computer interaction functions. The two communicate via the SPI+DMA (Direct Memory Access) bus.

[0032] Therefore, when the pairing request is sent to the target device to be operated and maintained via the video graphics array interface using the target bus, Figure 3 As shown, the operation and maintenance target of the target device to be operated and maintained can be received first, and based on the operation and maintenance target, it can be determined whether the connection mode between the current operation and maintenance device and the target device to be operated and maintained is hot-swappable; if the current connection mode is hot-swappable, it is determined whether the current target device to be operated and maintained meets the preset hot-swappable condition. If the target device to be operated and maintained meets the preset hot-swappable condition, the dynamic key and identification information of the target device to be operated and maintained are obtained through the local first preset logic device (i.e., FPGA2), and the target device to be operated and maintained is authenticated based on the dynamic key and identification information; if the target device to be operated and maintained is successfully authenticated, a pairing request is generated, and the pairing request is sent to the target device to be operated and maintained via the video graphics array interface using the target bus (SPI bus). The preset hot-swappable condition is that after the target device to be operated and maintained closes the second video graphics array interface, the voltage fluctuation of the current output voltage is less than a preset threshold, and the output voltage is provided by the preset hot-swappable power controller of the target device to be operated and maintained.

[0033] Step S12: After the pairing operation is successful, the operation and maintenance request is sent to the target device to be operated and maintained, so that the target device to be operated and maintained obtains its own work log according to the operation and maintenance request and sends the work log to the operation and maintenance device.

[0034] In this embodiment, after the pairing operation between the operation and maintenance device and the target device to be operated and maintained is successful, the operation and maintenance device can send an operation and maintenance request to the target device to be operated and maintained, so that the target device to be operated and maintained can obtain its own work log according to the operation and maintenance request and send the work log to the operation and maintenance device. Figure 3 As shown, the above-mentioned work log is: when the management controller (BMC) of the target device to be maintained is in normal working status, the work log is directly obtained by using the management controller; or when the management controller of the target device to be maintained is in abnormal working status, the work log is obtained by using the second preset logic device (FPGA1) of the target device to be maintained.

[0035] Step S13: Perform operation and maintenance on the target device to be operated and maintained based on the work log, and display corresponding operation and maintenance information based on the work log on a preset display interface.

[0036] In this embodiment, after the operation and maintenance device obtains the work log, it can perform operation and maintenance on the target device to be operated and maintained, and display corresponding operation and maintenance information based on the work log on the preset display interface of the display terminal (VGA Screen).

[0037] It should be noted that this embodiment is not limited to the operation and maintenance of a single motherboard, and can also support log acquisition and operation and maintenance of multiple motherboards. Figure 4 As shown, this embodiment will be described in conjunction with a specific scenario:

[0038] In a specific embodiment, there is a server chassis with n motherboards. The management board manages the BMC and BIOS (Basic Input / Output System) Flash boot of all nodes in the server chassis. The operation and maintenance equipment manages all node firmware, collects logs, and provides screen display. The chip models and functions of the device operation and maintenance system corresponding to this server are shown in the following table:

[0039] Table 1 Chip model and function diagram

[0040]

[0041] Accordingly, when hot-swapping operation and maintenance equipment, if it is determined that the operation and maintenance equipment needs to be hot-swapped, such as debugging the server firmware or collecting one-click logs offline, in order to prevent the inserted voltage from being too high and damaging the equipment, the hot-swap Button1 button should be pressed before insertion. After the button is pressed, the server management board FPGA1 turns off the VGA output and SPI output, and the TPS22965 gradually increases the power supply voltage to prevent inrush current from damaging the equipment. After the output voltage stabilizes, the status indicator LED (Light Emitting Diode) starts to flash slowly, waiting for the operation and maintenance equipment to be connected. After the operation and maintenance equipment is connected, FPGA1 and FPGA2 perform two-way authentication and dynamic key exchange, read each other's identification information, prevent illegal operation and maintenance equipment from using the operation and maintenance interface, and start the operation and maintenance function after successful pairing, such as Figure 3 The LED lights up steadily if pairing is successful, flashes quickly if pairing fails, and FPGA1 shields the SPI interface. The dynamic key is not limited to any key type; for example, it can be a key generated based on SHA-256 (Secure Hash Algorithm-256) and HMAC (Hash-based Message Authentication Code).

[0042] And when collecting logs, such as Figure 3 As shown, the STM32H743 first receives a user's request to collect one-click logs through information such as the screen and transmits this request to FPGA2. FPGA2 then notifies FPGA1 to obtain the one-click logs. FPGA1 then determines the node's BMC liveness and transmits different logs based on the BMC's liveness. If the BMC is alive, one-click logs are obtained from the BMC. If the BMC is down, FPGA1 transmits logs collected from the MB CPLD / Sensors and other sources. The collected logs are then stored back to the USB device via a process called FPGA1 → FPGA2 → STM32H743 → USB device, completing one-click log collection.

[0043] It should also be noted that since the server described above contains n motherboards, the bandwidth corresponding to each motherboard can be dynamically allocated based on a preset dynamic bandwidth allocation algorithm to improve data transmission efficiency. For example, in this embodiment, an SPI bus is constructed using the unused pins of the VGA interface (e.g., Pins 4, 11, 12, and 15) to transmit VGA video signals (e.g., the server startup screen) and BMC data (e.g., an overtemperature alarm for a node). BMC data is small in size but requires real-time response, while VGA signals are large in size and require uninterrupted transmission. Therefore, this embodiment monitors transmission requirements in real time. If the operation and maintenance device display is interrupted and the server screen is currently being displayed, the VGA signal bandwidth is increased to ensure smooth viewing. During firmware upgrades, the BMC bandwidth is temporarily increased. This allows bandwidth to be automatically allocated based on the current bus load, improving transmission efficiency and saving costs.

[0044] Through the above technical solution, this embodiment implements SPI bus multiplexing based on the reserved pins of the VGA interface. Specifically, a four-wire SPI bus is constructed using Pin 4 (SPI_CLK), Pin 11 (SPI_MOSI), Pin 12 (SPI_MISO), and Pin 15 (SPI_CS#). This supports the simultaneous transmission of multi-node BMC data and VGA video signals and integrates a dynamic bandwidth allocation algorithm. Furthermore, through a heterogeneous dual-core architecture comprising an FPGA and an STM32H743, the FPGA is dedicated to high-speed signal processing, while the STM32H743 Linux system implements human-computer interaction and USB communication. This solves the current problem of low O&M efficiency and high costs caused by hardware redundancy, achieving low latency for O&M equipment and significantly saving O&M time and costs. Furthermore, by pressing the hot-swap button before connecting an O&M device, the management board first disables the signal output and gradually increases the power supply voltage. Devices can then be connected only after the voltage stabilizes. Bidirectional authentication is also possible to prevent unauthorized access and enhance device security.

[0045] Based on the previous embodiment, it can be seen that the present application can construct a target bus based on the pins of the video graphics array interface for transmitting video signals, so that the target bus can be used to transmit data signals other than video signals through the video graphics array interface. Next, the specific process of device operation and maintenance will be described in detail in this embodiment. Figure 5 As shown, the embodiment of the present application provides a specific equipment maintenance method, including:

[0046] Step S21: Perform operation and maintenance on the target device based on the work log.

[0047] In this embodiment, Figure 2As shown in the figure, the operation and maintenance equipment adds the firmware upgrade / verification function. When operating and maintaining, the device is plugged into a USB device, and the ARM chip parses and reads the files in the USB device and transmits them to FPGA2. FPGA2 verifies the firmware information and transmits it to FPGA1. FGPA1 verifies it again and stores it in FlashB and notifies BMC. Specifically, Figure 3 As shown, first, the current firmware version of the target device to be maintained is determined according to the work log. If the firmware version does not meet the preset version requirement, the target firmware information is obtained through the local preset serial bus interface (USB Conn), and the target firmware information is sent to the local first preset logic device, and the target firmware information is verified by the first preset logic device; if the target firmware information passes the verification, the target firmware information is sent to the target device to be maintained, so that the target device to be maintained burns the target firmware information into its own cache unit (Flash B), and upgrades its own firmware according to the target firmware information in the cache unit.

[0048] In a specific embodiment, Figure 4 As shown, the STM32H743 first parses the firmware information in the USB device and transmits it to FPGA2. FPGA2 verifies the firmware and transmits the firmware information to FPGA1. After FPGA1 verifies the firmware is correct, it burns the firmware into Flash B for use by all node BMCs. This completes the unified firmware upgrade management. It should also be noted that the operation and maintenance operations that can be implemented in this embodiment are not limited to firmware upgrades; other corresponding operation and maintenance functions can be implemented using the operation and maintenance equipment in this embodiment.

[0049] Step S22: Display corresponding operation and maintenance information based on the work log on a preset display interface.

[0050] In this embodiment, when the preset display interface of the display terminal (VGA Screen) is used to display operation and maintenance information and other information, the operation and maintenance signal generated based on the work log can be obtained through the local preset serial bus interface, and the operation and maintenance signal can be sent to the preset signal controller (VGA Control) for format conversion to obtain operation and maintenance information, and then the operation and maintenance information is sent to the local preset information switching device (VGA Mux, i.e., multiplexer), and the current display content on the preset display interface is switched to the operation and maintenance information through the preset information switching device.

[0051] And as Figure 3As shown, in this embodiment, if an information switching command is received via the preset function button (Button 2), the device information of the target device to be maintained is sent to the preset information switching device, and the preset information switching device is used to switch the current display content on the preset display interface to the device information. The device information is the video signal obtained via the video graphics array interface. If an information switching command is received again, the preset information switching device stops receiving device information and switches the current display content on the preset display interface to the maintenance information.

[0052] That is to say, if Figure 2 As shown, in this embodiment, the management board not only adds a hot plug button Button1, when pressed, the management board FPGA1 stops transmitting signals and starts the hot plug process to prevent damage to the pins caused by hot plugging. At the same time, a VGA switch button Button2 is added to switch the chip display of the operation and maintenance equipment itself and the display of the server equipment on the screen. Figure 4 As shown, the VGA signal is transmitted to the AD8113, and Button2 controls the VGA display source switching. The STM32H743 then transmits its own video signal to the ADV7125, which converts the VGA signal and transmits it to the AD8113. The AD8113 outputs the STM32H743 screen by default. Each time Button2 is pressed, the screen switches to the screen, allowing maintenance personnel to check the screen display and switching.

[0053] Through the above technical solution, this embodiment constructs a server operation and maintenance device that uses the reserved pins of the VGA interface to build an SPI bus, integrates FPGA and ARM dual-core collaborative work, and supports hot-swappable access, multi-node real-time log collection, firmware burning, and dual-screen dynamic display switching. In this way, through the VGA reserved pins multiplexing the SPI bus, heterogeneous dual-core collaborative architecture and hot-swappable dynamic switching technology, a single operation and maintenance device can simultaneously realize the server's display / log collection / firmware refresh and other functions. It has the advantages of high integration, low latency, strong fault tolerance and intelligence, and can adapt to complex scenarios such as server cluster operation and maintenance and industrial control that require high reliability and real-time performance. In addition, through the coordinated optimization of physical layer signal multiplexing and dynamic resource scheduling algorithms, it can save a lot of operation and maintenance time and increase the security of firmware management.

[0054] like Figure 6 As shown, an embodiment of the present application further provides an equipment operation and maintenance device, which is applied to operation and maintenance equipment, including:

[0055] The device pairing module 11 is configured to send a pairing request to a target device to be maintained via a video graphics array interface using a target bus, so that the target device to be maintained can be paired with the maintenance device according to the pairing request. The target bus is a bus constructed based on preset pins of the video graphics array interface, and the preset pins are pins in the video graphics array interface used to transmit video signals.

[0056] The request sending module 12 is used to send the operation and maintenance request to the target device to be operated and maintained after the pairing operation is successful, so that the target device to be operated and maintained obtains its own work log according to the operation and maintenance request and sends the work log to the operation and maintenance device;

[0057] The equipment operation and maintenance module 13 is used to operate and maintain the target equipment based on the work log, and display corresponding operation and maintenance information based on the work log on a preset display interface.

[0058] In this embodiment, a target bus can be constructed based on the pins of the video graphics array interface for transmitting video signals, and then the target bus can be used to send a pairing request to the target device to be operated and maintained through the video graphics array interface, so that the target device to be operated and maintained can perform a pairing operation. Then, an operation and maintenance request can be sent to the target device to be operated and maintained, so that the target device to be operated and maintained can obtain a work log according to the operation and maintenance request and send it to the operation and maintenance device. Thereafter, the operation and maintenance device can operate and maintain the target device to be operated and maintained based on the work log and display corresponding operation and maintenance information on a preset display interface. In this way, by constructing a target bus based on the pins of the video graphics array interface for transmitting video signals, the target bus can be used to transmit data signals other than video signals through the video graphics array interface, and the target bus can be constructed by using idle pins, which solves the problem of the video graphics array interface being used only for video signal transmission and the reserved pins being idle for a long time, resulting in resource waste, and can save a lot of operation and maintenance time.

[0059] In some specific embodiments, the first video graphics array interface of the operation and maintenance device and the second video graphics array interface of the target device to be operated and maintained are connected via a target bus; accordingly, the device pairing module specifically includes:

[0070] The first information sending unit is used to send the target firmware information to the target device to be maintained if the target firmware information is verified, so that the target device to be maintained burns the target firmware information into its own cache unit and upgrades its own firmware according to the target firmware information in the cache unit.
