Description

Technical Field

[0001] The embodiments of the present application relate to the server field, and in particular, to a method and device for controlling the power supply of a bus device, a storage medium, and an electronic device. Background Art

[0002] In the related art, in order to ensure the stable operation of the bus device of the server bus port, the design of the power supply circuit of the bus device power supply is particularly important. Taking the bus device including the USB device as an example, the power supply circuit architecture of the USB power supply mainly relies on the POL power module and the EFUSE module. However, this architecture may have the problem of low safety of USB power supply operation when the USB port is short-circuited.

[0003] For example, taking the bus device power supply including the POL power module and the EFUSE module as an example, when P5V_USB is short-circuited (i.e., the USB port is short-circuited), the instantaneous current is very large, and the EFUSE module short-circuit protection has not yet responded, and the voltage of P5V_STBY (i.e., the board) drops instantly, causing the FB voltage fed back by the POL power module to be lower than VUVP (80% of the VREF voltage), and undervoltage protection occurs. The POL power module will no longer have output, and the AC power needs to be cut off and restarted to return to normal; at the same time, when the POL power module has SCP protection, the POL power module will restart, and there is a risk of burning the POL power module; in addition, when P5V_USB is short-circuited, the EFUSE module has SCP protection, and the CPLD (Complex Programmable Logic) Device, complex programmable logic device) module will send P5V_USB_EN (USB enable) command multiple times to restart the EFUSE module, which may burn the EFUSE module; when P5V_USB and P5V_STBY are short-circuited, the system cannot directly sense and report the short-circuit fault, and the customer cannot sense the short-circuit fault, which may cause the risk of burning the board and affect maintenance efficiency.

For example, the data transmission device may include but is not limited to a switch, and the data computing device may include but is not limited to a server, etc.

[0043] Optionally, in this embodiment, the bus port may include but is not limited to a port on a data processing device that satisfies a bus protocol, such as a USB (Universal Serial Bus) port or a PCIE (Peripheral Component Interconnect Express) port, etc.

[0044] Optionally, in this embodiment, the bus device power supply may include but is not limited to an independent power supply in the data processing device for powering the connected bus device, or the bus device power supply may also include but is not limited to a power supply in the total power supply in the data processing device for powering the connected bus device.

[0047] Optionally, in this embodiment, the first power supply may be, but is not limited to, used to power the second power supply, for example, the first power supply may be, but is not limited to, a POL power supply. The second power supply may be, but is not limited to, used to power the bus device, for example, the second power supply may be, but is not limited to, an EFUSE module.

[0048] Figure 3 is a schematic diagram of a structure of an optional bus device power supply according to an embodiment of the present application, such as Figure 3 As shown, it can be explained by taking, but not limited to, an example in which the bus device includes a USB device, the first power supply includes a POL power supply, the second power supply includes an EFUSE module, the first detection pin includes a PG (Power Good) pin in the POL power supply, the second detection pin includes a FAULT (fault) pin in the EFUSE module, the first status signal includes a P5V_STBY_PG signal, and the second status signal includes a P5V_USB_FAULT signal.

[0049] The PG pin in the POL power supply can be used but is not limited to outputting a P5V_STBY_PG signal, and the FAULT pin in the EFUSE module can be used but is not limited to outputting a P5V_USB_FAULT signal, wherein the P5V_STBY_PG signal can be used but is not limited to indicating the relationship between the voltage output by the POL power supply and the first voltage threshold, and the P5V_USB_FAULT signal can be used but is not limited to indicating the relationship between the voltage output by the EFUSE module and the second voltage threshold.

[0050] P12V_STBY can be used to power the POL power supply, but is not limited to being used to power the POL power supply. P12V_STBY is converted to P5V_STBY by the POL power supply module, where P5V_STBY can be used to power the EFUSE module, but is not limited to being used to power the EFUSE module. P5V_STBY is converted to P5V_USB by the EFUSE module, where P5V_USB can be used to power the bus device connected to the USB port, but is not limited to being used to power the bus device connected to the USB port. P12V_STBY is divided by resistors R11 and R12 to obtain the P5V_STBY_EN signal, where the P5V_STBY_EN signal is used to indicate whether the POL power supply module is running or stopping, and provides an enable EN (Enable) to the POL power supply module. The P5V_USB_EN signal is used to indicate whether the EFUSE module is running or stopping.

[0051] Optionally, in this embodiment, it is possible but not limited to determining that the voltage output by the first power supply is greater than the first voltage threshold when the first state signal includes a high-level signal, and determining that the voltage output by the first power supply is less than or equal to the first voltage threshold when the first state signal includes a low-level signal; it is possible but not limited to determining that the voltage output by the second power supply is greater than the second voltage threshold when the second state signal includes a high-level signal, and determining that the voltage output by the second power supply is less than or equal to the second voltage threshold when the second state signal includes a low-level signal.

[0052] Optionally, in this embodiment, when the first state signal is used to indicate that the voltage output by the first power supply is greater than a first voltage threshold, and when the second state signal is used to indicate that the voltage output by the second power supply is greater than a second voltage threshold, the target power supply state can be determined, but is not limited to, as indicating that the voltage output by the bus device power supply is greater than the target voltage threshold.

[0053] Through the embodiments of the present application, the power supply status of the bus device power supply can be monitored in real time to ensure that the power supply output voltage is within a safe threshold range. When the voltage is lower than the voltage threshold, the startup control device can respond quickly, thereby improving the stability and safety of the power supply circuit of the bus device power supply.

[0054] In the technical solution provided in the above step S204, when the power supply state indicates that the voltage output by the bus device power supply is less than or equal to the target voltage threshold, the bus device power supply may, but is not limited to, have undervoltage protection. The undervoltage protection may, but is not limited to, stop the output of the POL power module when the voltage output by the bus device power supply is less than or equal to the target voltage threshold, so as to prevent the current surge caused by the low voltage from causing damage to the circuit or the bus device power supply or the connected bus device, etc. For example, it may, but is not limited to, the bus device includes a USB device, combined with Figure 3 To explain, when P5V_USB is short-circuited, the instantaneous current is very large, and the P5V_STBY voltage drops instantly, causing the POL power module (equivalent to the first power supply) to feedback the FB voltage lower than VUVP (Under Voltage Protection, 80% of VREF voltage), and undervoltage protection occurs. The POL power module will no longer have output, and the AC (Alternating Current) power must be cut off and restarted. Since the POL power supply supplies power to the EFUSE module, when the POL power module is undervoltage protected, the EFUSE module also has no output, and the AC power must be cut off and restarted.

[0067] Optionally, in this embodiment, after sending the first fault information to the management controller, a repair instruction may be sent to the first power supply, wherein the repair instruction is used to repair the first fault occurring in the first power supply, or first identification information of the faulty power supply may be extracted from the first fault information, and the first power supply corresponding to the first identification information is replaced, wherein the first fault information carries the first identification information; after sending the second fault information to the management controller, second identification information of the faulty bus device may be extracted from the second fault information, but is not limited to, and the bus device corresponding to the second identification information is replaced, wherein the second fault information carries the second identification information.

[0068] Through the embodiments of the present application, after fault information is sent to the management controller, targeted repair or replacement measures are taken based on the fault information, thereby achieving efficient fault management and rapid response of the bus device power supply and connected bus devices, and significantly improving the active fault management capabilities and maintenance efficiency.

[0069] Optionally, in this embodiment, the management controller may be, but is not limited to, used to receive fault information sent by the startup control device, for example, a BMC controller.

[0070] Optionally, in this embodiment, the first fault type may include but is not limited to a first short circuit type, and the second fault type may include but is not limited to a second short circuit type.

[0071] Optionally, in this embodiment, if the voltage output by the first power supply and the second power supply is abnormal, but there is no short circuit between the first power supply and the connected bus device, it can be indicated that the above-mentioned abnormal power supply state may be just a temporary fluctuation of the circuit, or other faults that can be directly restarted have occurred. In such a case, it is possible but not limited to first turning off the first power supply and the second power supply, and restarting the first power supply and the second power supply after an interval of a reference time (for example, 500ms or 1 minute, etc., which is not limited in this application); or, directly restarting the first power supply and then restarting the second power supply.

[0072] Figure 4 is a circuit diagram of an optional server bus device power supply according to an embodiment of the present application, such as Figure 4As shown, it is possible but not limited to taking bus devices including USB devices as an example, through the single-chip control system (equivalent to the controller) and the new enable signal P5V_STBY_EN_MOS (equivalent to the first control signal) to manage the POL power module (equivalent to the first power supply), which solves the problem that when P5V_USB is short-circuited, the instantaneous current is very large, the P5V_STBY voltage drops instantly, causing the POL power module feedback FB voltage to be lower than the starting VUVP (80% of the VREF voltage), causing undervoltage protection, the POL power module will no longer have output, and the AC power needs to be cut off and restarted.

[0073] When a short circuit of P5V_USB is detected and the voltage of P5V_STBY is reduced, the MCU control system can respond immediately and output the P5V_STBY_EN_MOS signal to the POL power module to control the enable state of the POL power module, thereby suppressing the output of P5V_STBY in a short time and preventing the POL power module from entering the protection mode due to undervoltage. When the system returns to normal, the MCU control system will re-enable the POL power module, so that the POL power module will work again and output P5V_STBY, thereby enhancing the stability and reliability of the USB power supply circuit.

[0074] At the same time, when P5V_USB is short-circuited, the EFUSE module (equivalent to the second power supply) undergoes SCP protection, and the single-chip control system will continuously detect the short-circuit state of P5V_USB. When the short-circuit state of P5V_USB is eliminated, the EFUSE module will work again and output P5V_USB, which solves the problem in the related technology that when P5V_USB is short-circuited, the EFUSE module undergoes SCP protection, and the CPLD module will send P5V_USB_EN (equivalent to the second enable signal) instruction multiple times to restart the EFUSE module, which has the risk of burning the EFUSE module, thereby improving the safety of the power supply circuit of the bus device power supply.

[0091] The embodiment of the present application provides a circuit for powering a bus device for a server, which may include but is not limited to: a POL power module, an EFUSE module, a short circuit detection circuit, a single-chip control system, and a BMC controller, and each module is directly connected through an electrical signal. The short circuit detection circuit detects the short circuit state of the P5V_STBY and P5V_USB circuits and transmits it to the single-chip control system. The single-chip control system receives the P5V_STBY_PG (equivalent to the first state signal) signal of the POL power module, the P5V_USB_FAULT signal (equivalent to the second state signal) of the EFUSE module, the P5V_STBY_SHORT signal (equivalent to the first detection signal) of the short circuit detection circuit, and the P5V_USB_SHORT signal (equivalent to the second detection signal). The single-chip control system performs logical operations according to the states of the above signals, obtains calculation results, and transmits them to the corresponding modules. The single-chip control system transmits the P5V_STBY_EN_MOS signal (equivalent to the first control signal) to the POL power module and the P5V_USB_EN signal (equivalent to the second enable signal) to the EFUSE module. The single-chip microcomputer control system can, but is not limited to, transmit the USB short circuit and board short circuit signals to the BMC controller through I2C communication.

[0092] 1) POL power module:

[0093] The POL power module converts P12V_STBY to P5V_STBY to supply power to the EFUSE module. The POL power module compares the voltage of the feedback point FB (Feedback) with the internal reference voltage VREF (Reference Voltage) to adjust the output of P5V_STBY. When the output voltage of P5V_STBY is normal, P5V_STBY_PG is high and is transmitted to the microcontroller control system.

[0094] The POL power module receives the P5V_STBY_EN_MOS signal transmitted by the single-chip control system to realize the conduction and disconnection of Q21, and pulls down the P5V_STBY_EN signal for a short time, thereby realizing the restart of the POL power module under abnormal protection.

[0095] 2) EFUSE module:

[0096] The EFUSE module converts P5V_STBY to P5V_USB, supplies power to the USB port, and implements OCP (Over Current Protection) and SCP (Short Circuit Protection) protection functions for the USB port. When the P5V_USB output voltage is normal, the P5V_USB_FAULT signal is high and is transmitted to the microcontroller control system. The EFUSE module receives the P5V_USB_EN signal transmitted by the microcontroller control system to start and stop the EFUSE module.

[0097] 3) Short circuit detection circuit:

[0098] The short-circuit detection circuit detects the status of the output P5V_STBY of the POL power module and the output P5V_USB of the EFUSE module. If P5V_STBY is short-circuited, the P5V_STBY_SHORT signal is set to 1, otherwise it is set to 0. If P5V_USB is short-circuited, the P5V_USB_SHORT signal is set to 1, otherwise it is set to 0. The short-circuit detection circuit transmits the P5V_STBY_SHORT signal and the P5V_USB_SHORT signal to the single-chip control system.

[0099] 4) Single chip microcomputer control system:

[0100] The single-chip control system receives the P5V_STBY_PG signal of the POL power module, the P5V_USB_FAULT signal of the EFUSE module, the P5V_STBY_SHORT signal and the P5V_USB_SHORT signal of the short-circuit detection circuit. The single-chip control system transmits the P5V_STBY_EN_MOS signal to the POL power module and the P5V_USB_EN signal to the EFUSE module. The single-chip control system transmits the USB short circuit and board short circuit signals to the BMC controller through I2C communication.

[0101] The single-chip control system determines the fault type of the system by detecting the status of the P5V_STBY_PG signal, P5V_USB_FAULT signal, P5V_STBY_SHORT signal, and P5V_USB_SHORT signal, and transmits these fault information to the BMC controller through the SDA line (Serial Data Line) and SCL (Serial Clock Line) of the I2C bus. After a period of time, if the system short circuit fault is eliminated, the single-chip control system transmits the corresponding status of the P5V_STBY_EN_MOS signal to the POL power module and the corresponding status of the P5V_USB_EN signal to the EFUSE module, so that the POL power module and the EFUSE module can resume normal operation.

[0102] 5) BMC controller:

[0103] The BMC controller receives USB short circuit and board short circuit signals transmitted by the single-chip control system through I2C communication, and displays the signals through the WEB (World Wide Web) to inform maintenance personnel of the corresponding fault information.

[0104] It should be noted that the technical solution of the present invention can be applied not only to the control of the power supply of bus devices in servers, but also to other devices requiring high-reliability power management, for example, power management and fault handling of network devices such as switches.

[0105] In an exemplary embodiment, when the switching device receives the first control signal of a high level, the switching device is turned on. When the switching device is turned on, the first enable signal of the first power supply is at a low level, wherein the first enable signal of the low level is used to control the first power supply to stop operating; when the switching device receives the first control signal of a low level, the switching device is turned off. When the switching device is turned off, the first enable signal of the first power supply is at a high level, wherein the first enable signal of the high level is used to control the first power supply to operate.

[0106] Optionally, in this embodiment, the switching device may include but is not limited to an electronic component that controls the first enable signal, such as a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), an IGBT (Insulated Gate Bipolar Transistor), and the like.

Figure 5 As shown, the control method for controlling the power supply of the bus device may be implemented as follows, but is not limited to, taking the controller including a single-chip microcomputer control system, the management controller including a BMC controller, the detector including a short-circuit detection circuit, the bus device including a USB device, the first power supply including a POL power supply module, the second power supply including an EFUSE module, and the switch device including a MOSFET as an example:

[0109] Step 1: Set the connection relationship between the POL power module, EFUSE module, short circuit detection circuit, single chip control system, and BMC controller on the system.

[0110] Step 2: When the system is operating normally, the microcontroller control system outputs P5V_STBY_EN_MOS=0, Q21 (equivalent to the switching device) is not conducting, P5V_STBY_EN (equivalent to the first enable signal)=1, then the POL power module works normally and outputs P5V_STBY; when the system is operating normally, the microcontroller control system outputs P5V_USB_EN (equivalent to the second enable signal)=1, then the EFUSE module works normally and outputs P5V_USB.

[0111] Step 3: If OCP or SCP protection occurs on P5V_USB, the P5V_USB_FAULT signal (equivalent to the second state signal) changes from high level to low level. Due to the instantaneous large impact current, P5V_STBY drops instantly, and the voltage at the FB feedback point of the POL power module drops instantly, which may cause UVP (Under Voltage Protection) protection on the POL power module, and the P5V_STBY_PG signal changes from high level to low level.

[0112] Step 4: If the POL power module experiences OCP, SCP, OVP (Over Voltage Protection), or UVP protection, the P5V_STBY_PG signal (equivalent to the first state signal) changes from a high level to a low level.

[0113] Step 5: The short-circuit detection circuit detects the status of the output P5V_STBY of the POL power module and the output P5V_USB of the EFUSE module. If P5V_STBY is short-circuited, the P5V_STBY_SHORT signal (equivalent to the first detection signal) is set to 1, otherwise it is set to 0. If P5V_USB is short-circuited, the P5V_USB_SHORT signal (equivalent to the second detection signal) is set to 1, otherwise it is set to 0.

[0114] Step 6: The short-circuit detection circuit transmits the P5V_STBY_SHORT signal and the P5V_USB_SHORT signal to the microcontroller control system.

[0115] Step 7: The single-chip microcomputer control system detects the status of the P5V_STBY_SHORT signal, the P5V_USB_SHORT signal, the P5V_STBY_PG signal, and the P5V_USB_FAULT signal.

[0116] Step 8: If only the falling edge of the P5V_USB_FAULT signal is detected and the EFUSE module is protected, the state of the P5V_USB_SHORT signal is determined.

[0117] 1) If P5V_USB_SHORT=0, there is no short circuit in P5V_USB, and the EFUSE module is restarted. The P5V_USB_EN signal is first set to 0, and then set to 1 after 500ms (milliseconds), so that the EFUSE module restarts and outputs P5V_USB, and the system resumes normal operation.

[0118] 2) If P5V_USB_SHORT=1, P5V_USB is short-circuited, which may be caused by an external USB device. Wait for 1 minute, add 1 to counter N1, and then loop to detect the state of P5V_USB_SHORT signal until P5V_USB_SHORT=0, and then run the content of step 8 1), and N1 is cleared at the same time.

[0119] If N1=10, it means that after waiting for 10 minutes, the USB port short circuit fault has not been restored. In this case, the USB port short circuit information (equivalent to the second fault information) is transmitted to the BMC controller through I2C communication.

[0120] Step 9: If the falling edges of the P5V_USB_FAULT signal and the P5V_STBY_PG signal are detected at the same time, the POL power module and the EFUSE module are protected at the same time, and the state of the P5V_STBY_SHORT signal is determined.

[0121] 1) If P5V_STBY_SHORT=1, P5V_STBY is short-circuited (i.e., the board is short-circuited), and the board short-circuit is transmitted to the BMC controller through I2C communication.

[0122] 2) If P5V_STBY_SHORT=0, P5V_STBY is not short-circuited, then determine the status of the P5V_USB_SHORT signal.

[0123] a) If P5V_USB_SHORT=0, P5V_USB has no short circuit, and the POL power module and EFUSE module are restarted at the same time.

[0124] The P5V_STBY_EN_MOS signal (equivalent to the first control signal) is set to 1 first, and then set to 0 after 500ms, so that the POL power module restarts and outputs P5V_STBY. The P5V_USB_EN signal is set to 0 first, and then set to 1 after 500ms, so that the EFUSE module restarts and outputs P5V_USB, and the system resumes normal operation.

[0125] b) If P5V_USB_SHORT=1, P5V_USB is short-circuited, which may be caused by an external USB device. Wait for 1 minute, add 1 to counter N2, and then loop to detect the state of P5V_USB_SHORT signal until P5V_USB_SHORT=0, and then run the content of step 9, 2) a), and clear N2 at the same time.

[0126] If N2=10, it means that after waiting for 10 minutes, the USB port short circuit fault has not been restored. In this case, the USB short circuit information (equivalent to the second fault information) is transmitted to the BMC controller through I2C (Inter-Integrated Circuit, two-wire serial bus) communication.

[0127] Through the embodiments of the present application, it is possible but not limited to taking the bus device including the USB device as an example. When it is detected that the P5V_USB short circuit has not returned to normal within the set time, the single-chip microcomputer control system outputs P5V_USB_EN=0, turns off the EFUSE module, and the single-chip microcomputer control system transmits the USB short circuit to the BMC controller through I2C communication, thereby solving the problem that when P5V_USB and P5V_STBY are short-circuited, the system cannot perceive it and cannot inform the customer through the BMC. This enables maintenance personnel to quickly locate the problem and take timely measures to restore the normal operation of the system or replace the faulty equipment, thereby improving the operation and maintenance efficiency of the server.

[0128] At the same time, when it is detected that the P5V_STBY short circuit has not returned to normal within the set time, the single-chip microcomputer control system outputs P5V_STBY_EN_MOS=1, turns off the POL power module, and the single-chip microcomputer control system transmits the board short circuit to the BMC controller through I2C communication, which solves the problem that the POL power module will restart when SCP protection occurs, and there is a risk of burning the POL power module. Maintenance personnel can promptly understand the board short circuit and take necessary measures, such as power-off inspection and replacement of faulty boards, to prevent further damage to the system, thereby improving the safety of the power supply circuit of the bus device power supply and the convenience of operation and maintenance.
