[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Figure 1 An exemplary system architecture 100 is shown to which embodiments of the fault recovery method or fault recovery apparatus of the present disclosure may be applied.

[0030] like Figure 1 As shown, system architecture 100 may include terminal device 101, network 102, and server 103. Network 102 is used to provide a medium for a communication link between terminal device 101 and server 103. Network 102 may include various connection types, such as wired or wireless communication links or fiber optic cables.

[0031] The user can use the terminal device 101 to interact with the server 103 via the network 102, for example, to send repair data to the server 103. Various communication client applications, such as traffic detection applications, can be installed on the terminal device 101.

[0032] The server 103 may be a server that provides various services, in which a plurality of core boards and a baseboard management controller may be installed. The baseboard management controller may interact with the plurality of core boards and perform fault repair on the core board when a core board fails.

[0033] It should be noted that the fault repair method provided in the embodiment of the present disclosure is generally executed by the baseboard management controller and the core board in the server 103. Accordingly, the fault repair device is generally provided in the baseboard management controller and the core board in the server 103.

[0034] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0035] Continue to refer Figure 2 , shows a schematic structural diagram of an embodiment of a core board according to the present disclosure. Figure 2As shown, the core board 200 of this embodiment may include: a forced download switch 201 , a system on chip (SOC) 202 , a power supply 203 and a USB interface 204 .

[0036] Among them, the forced download switch 201 is communicatively connected with the system-on-chip 202. At the same time, the forced download switch 201 can also receive a forced download signal sent by an external device outside the core board 200. After receiving the above-mentioned forced download signal, the forced download switch 201 can change its own state, such as adjusting the electrical signal value to a preset value. The electrical signal here can be a voltage value or a current value. The forced download switch 201 can adjust the above-mentioned electrical signal value, such as adjusting the electrical signal value from a low level to a high level, or adjusting the electrical signal value from a high level value to a low level value.

[0037] While powered on, the SoC 202 can monitor the electrical signal value of the forced download switch 201 in real time. If the electrical signal value of the forced download switch 201 reaches a preset value, it can be determined that forced downloading of repair data is required to perform a forced fault repair. The repair data can include multiple lines of code, which the SoC 202 can execute to perform a flash or fault repair.

[0038] The power supply 203 is used to power the SoC 202. The power supply 203 can also receive a power control signal from an external device outside the core board 200 and control the power supply according to the power control signal. The SoC 202 can be powered on or off under the control of the power control signal.

[0039] The core board 200 may also be provided with a USB interface 204, which can be connected to an external device outside the core board 200 to receive the repair data sent by the external device. The USB interface can send the repair data to the system-on-chip 202 to achieve forced downloading of the repair data.

[0040] In some optional implementations of this embodiment, the power supply 203 may be further configured to, under the control of a power control signal, first power off and then power on the SoC 202. After powering on, the SoC 202 may enter a repair mode, i.e., execute the program or code in the repair data to repair the fault.

[0041] The core board provided by the above-mentioned embodiments of the present disclosure can receive repair data from an external device through a USB interface, and control the system-level chip by forcing a download switch and power supply, so that the system-level chip can use the repair data to repair faults under the above-mentioned control, thereby improving the fault repair efficiency of the core board.

[0042] Continue to see Figure 3 , which shows a structural diagram of another embodiment of the core board according to the present disclosure. Figure 3 As shown, the core board 300 of this embodiment may include: a microcontroller unit (MCU) 301 , a forced download switch 302 , a power supply 303 , a system-on-chip 304 and a USB interface 305 .

[0043] Among them, the micro control unit 301 is connected to the forced download switch 302 and the power supply 303. The micro control unit 301 can interact with external devices outside the core board 300, such as receiving a fault repair instruction sent by an external device. The micro control unit 301 can send a forced download signal to the forced download switch 302 when receiving the above-mentioned fault repair instruction. At the same time, a power control signal is sent to the power supply 303. The forced download switch 302 can adjust its own state when receiving the forced download signal, such as adjusting the electrical signal value. For example, the electrical signal value can be set to a preset value. The power supply 303 can control the power supply to the system-level chip 304 after receiving the power control signal.

[0044] The system-on-chip 304 can also be in communication with the USB interface 305. When the system-on-chip 304 detects that the electrical signal value of the forced download switch 302 is a preset value, it can use the repair data received from the outside through the USB interface 305 to perform fault repair.

[0045] The USB interface 305 can interact with external devices outside the core board 300 , for example, receive repair data sent by the external device and send the repair data to the system-on-chip 304 .

[0046] In some optional implementations of this embodiment, the power supply 303 may be further configured to, under the control of the power control signal, first power off and then power on the SoC 304. After powering on, the SoC 304 may enter a repair mode, i.e., execute the program or code in the repair data to repair the fault.

[0047] The core board provided by the above embodiment of the present disclosure can realize the fault repair of the core board by setting an MCU in the core board and controlling each component in the core board through the MCU. Figure 2 As shown in the core board, the core board of this embodiment has fewer connecting lines with external devices, so less wiring space is required, which facilitates the heat dissipation of the server and can also reduce the size of the server.

[0048] See also Figure 4 , which shows a schematic diagram of the structure of an embodiment of a server according to the present disclosure. Figure 4As shown, the server 400 of this embodiment may include a baseboard management controller (BCM) 401 and at least one core board 402. The core board here may be Figure 2 The core board shown can also be Figure 3 The core board shown.

[0049] BCM 401 can receive the core board fault information sent externally. The external part here can be a device outside the server 400, such as a terminal for managing each server, and the terminal can carry out data monitoring to the core board in each server. If it is found that a certain core board has no output, or cannot be connected, it is considered that the core board is faulty. The core board fault information can be generated according to the position of the core board of fault. And the above-mentioned core board fault information is output to BCM 401. BCM 401 can analyze after receiving the above-mentioned core board fault information, and determines the position of the core board of fault. Here, the core board of fault is called the target core board.

[0050] The target core board 402 can interact with the BCM 401, for example, it can receive a forced download signal sent by the BCM 401. And after receiving the above-mentioned forced download signal, it is determined that fault repair is currently needed. At this time, the target core board 402 can receive repair data from the BCM 401 to repair the fault. Here, the fault repair can be to flash the target core board 402.

[0051] The server provided by the above-mentioned embodiment of the present disclosure can implement core board fault repair by installing BCM therein, thereby eliminating the need to remove the core board from the server, thereby improving the efficiency of core board fault repair.

[0052] In some optional implementations of this embodiment, the BCM 401 may obtain the repair data from an external device. Specifically, the BCM 401 may obtain the repair data from a terminal device that monitors and manages the server 400 .

[0053] Continue to see Figure 5 , which shows a schematic diagram of the structure of the server according to the present disclosure. Figure 5 As shown, the server 500 of this embodiment may include a BCM 501 and a target core board 502 . The target core board 502 may include a forced download switch 5021 , a system-on-chip 5022 , a power supply 5023 , and a USB interface 5024 .

[0054] The forced download switch 5021 is communicatively connected to the system-on-chip 5022. The forced download switch 5021 can also receive a forced download signal sent by the BCM 501. Upon receiving the forced download signal, the forced download switch 5021 can change its state, for example, by adjusting the value of an electrical signal to a preset value. The electrical signal can be a voltage or a current. The forced download switch can adjust the value of the electrical signal, for example, from a low level to a high level, or from a high level to a low level.

[0055] When powered on, the SoC 5022 can monitor the electrical signal value of the forced download switch 5021 in real time. If the electrical signal value of the forced download switch 5021 reaches a preset value, it can be determined that forced download of repair data is required to perform a forced fault repair. The repair data can include multiple lines of code, and the SoC 5022 can execute these multiple lines of code to perform a flash or fault repair.

[0056] The power supply 5023 is used to supply power to the SoC 5022. The power supply 5023 can also receive a power control signal from the BCM 501 and control the power supply according to the power control signal. The SoC 5022 can be powered on or off under the control of the power control signal.

[0057] The target core board 502 may also be provided with a USB interface 5024, which can be connected to the BCM 501 for communication to receive repair data sent by an external device. The USB interface 5024 can send the repair data to the system-on-chip 5022 to achieve mandatory downloading of the repair data.

[0058] In this embodiment, the BCM 501 may be connected to the forced download switch 5021 via a first connection line, connected to the power supply 5023 via a second connection line, and connected to the USB interface 5024 via a third connection line.

[0059] The server provided by the above-mentioned embodiment of the present disclosure can implement fault repair of the core board through BCM, thereby improving the efficiency of fault repair.

The target core board 602 may include a micro control unit 6021 , a forced download switch 6022 , a power supply 6023 , a system-on-chip 6024 and a USB interface 6025 .

[0061] The microcontroller unit 6021 is connected to the forced download switch 6022 and the power supply 6023. The microcontroller unit 6021 can interact with the BCM 601, for example, receiving fault repair instructions sent by the BCM 601. Upon receiving the fault repair instructions, the microcontroller unit 6021 can send a forced download signal to the forced download switch 6022. Simultaneously, it can send a power control signal to the power supply 6023. Upon receiving the forced download signal, the forced download switch 6022 can adjust its state, for example, by adjusting the electrical signal value. For example, the electrical signal value can be set to a preset value. Upon receiving the power control signal, the power supply 6023 can control the power supply to the system-on-chip 6024.

[0062] The system-on-chip 6024 can also be connected to the USB interface 6025. When the system-on-chip 6024 detects that the electrical signal value of the forced download switch 6022 is a preset value, it can use the repair data received from the outside through the USB interface 6025 to perform fault repair.

[0063] The USB interface 6025 can interact with the BCM 601 , for example, receive repair data sent by an external device and send the repair data to the system-on-chip 6024 .

[0064] In this embodiment, the BCM 601 may be connected to the micro control unit 6021 via a fourth connection line, and connected to the power supply 6023 via a fifth connection line.

[0065] In some optional implementations of this embodiment, the power supply 6023 may power off the system-on-chip 6022 and then power it back on when receiving a power control signal.

[0067] Step 701 : In response to receiving core board fault information, a target core board is determined from at least one core board in communication connection according to the core board fault information.

[0068] In this embodiment, the baseboard management controller may receive core board fault information. After receiving the core board fault information, the baseboard management controller may analyze the core board fault information and determine the target core board from at least one core board in communication connection. Specifically, the core board fault information may include location information of the core board, where the location information may refer to the location of the core board in the server.

[0069] Step 702 : In response to receiving the repair data, a control signal is sent to the target core board, and the repair data is sent to the target core board, so that the target core board uses the repair data to perform fault repair according to the control signal.

[0070] After determining the target core board, the baseboard management controller can also receive repair data from the outside, send a control signal to the target core board, and send the repair data to the target core board. After receiving the control signal and repair data, the target core board can use the repair data to repair the fault.

[0073] In some optional implementations of this embodiment, when a control signal is sent to the power supply, the power supply may be caused to power off the system-on-chip and then power on again.

[0074] The fault repair method provided by the above-mentioned embodiment of the present disclosure can use BCM to repair the core board fault, thereby improving the fault repair efficiency.

[0080] Accordingly, the core board can perform fault repair through the following steps: in response to receiving the forced download signal, the control system-level chip performs fault repair using the repair data under the control of the power control signal.

[0081] In this implementation, the core board can obtain the forced download signal, the repair data, and the power control signal through the first connection line, the second connection line, and the third connection line, respectively. After receiving the forced download signal, the core board can confirm that fault repair is currently required, that is, control the system-level chip to perform fault repair using the repair data under power control.

[0082] In some optional implementations of this embodiment, the core board includes a microcontroller unit, a forced download switch, a power supply, a USB interface, and a system-on-chip. The control signal includes a forced repair instruction. The core board can receive data through the following steps: receiving the forced repair instruction from the vehicle body manager via a fourth connection line; and receiving repair data from the baseboard management controller via a fifth connection line and the USB interface.

Simultaneously, it can receive repair data from the baseboard management controller via the fifth connection line and the USB interface.
