Description

Technical Field

[0001] This application relates to the field of computers, and more specifically, to a fan control method and apparatus, a storage medium, and an electronic device. Background Technology

[0002] Currently, in the hardware design of equipment (such as servers), due to structural limitations, a fan power supply board is typically used. This board controls the power supply to the entire machine while also controlling the machine's fans. Furthermore, the Baseboard Manager Controller (BMC) accesses the fan power supply board to obtain power status information and control the fans.

[0003] In related technologies, the motherboard and fan power supply board are connected via cables. The motherboard's BMC (Browser Control Center) uses an I2C bus (a bidirectional two-wire synchronous serial bus, a communication bus) to access and control the fan power supply board. By accessing the VR chip (power conversion chip) on the fan power supply board, it obtains the current power consumption of the machine and sends fan speed information to the Complex Programmable Logic Device (CPLD) on the board to control the fan speed. Simultaneously, the BMC's watchdog timer circuit signal (WDT signal) is connected to the fan board; the CPLD detects whether the WDT signal periodically reverses to determine if the BMC is stuck. When the CPLD detects a BMC stuck, it takes over fan control and determines different fan speeds based on the power-on signal sent by the motherboard. Since the BMC does not participate in fan control when the machine is powered off, the CPLD takes over fan control during power-off conditions. All of the aforementioned BMC I2C signal, WDT signal, and power-on signal must be included in the cable between the motherboard and the fan power supply board.

[0004] Therefore, to ensure the fan power supply board functions properly, related technologies require not only a BMC I2C signal but also a BMC WDT signal sent from the motherboard to the fan power supply board and a motherboard power-on signal. However, these two signals have no actual function during normal machine operation, occupying additional cable routing and increasing design costs; at the same time, the increased number of cables reduces the machine's reliability.

[0005] There is currently no effective solution to the problem that the use of power-on signals and watchdog timer signals sent by the motherboard in related technologies to control the fan speed in the device increases the number of cables, resulting in higher cable costs and lower reliability.

[0038] The embodiments of this application will be described in detail below with reference to the accompanying drawings and examples.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0040] The methods and embodiments provided in this application can be executed on mobile terminals, computer terminals, or similar computing devices. Figure 1 This is a hardware structure block diagram of a mobile terminal for a fan control method according to an embodiment of this application. Figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more processors 102 (shown as 102a, 102b, ..., 102n in the figure) (processor 102 may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission module 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of a BUS bus), a network interface, a power supply, and / or a camera. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the aforementioned electronic device. For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0041] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof. Furthermore, the data processing circuits may be a single, independent processing module, or may be integrated, in whole or in part, into any other element within the computer terminal 10 (or mobile device). As involved in the embodiments of this application, the data processing circuits serve as a processor control mechanism (e.g., selection of a variable resistor termination path connected to an interface).

[0042] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the fan control method in this embodiment. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, thereby realizing the aforementioned fan control method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0043] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the communication provider of the computer terminal 10. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0044] This embodiment provides a method that runs on the aforementioned mobile terminal. Figure 2 This is a flowchart of a fan control method according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0045] Step S201: Obtain the target signal from the target device, wherein the target device includes at least a motherboard and a power board, and the target signal is generated when the baseboard management controller in the motherboard interacts with the power conversion chip in the power board, and the power board includes at least a power conversion chip and a fan.

[0046] For example, the target device mentioned above could be a server. Furthermore, Figure 3 This is a schematic diagram of the structure of a fan control system according to an embodiment of this application, as shown below. Figure 3 As shown, the system includes: a Baseboard Manager Controller (BMC) on the motherboard of the server, a Complex Programmable Logic Device (CPLD) and a power conversion chip (VR chip) on the fan power supply board of the server, and a fan (FAN). Furthermore, the BMC and CPLD in the system are connected via an I2C bus (a bidirectional two-wire synchronous serial bus, a type of communication bus), and the CPLD and VR chip are also connected via an I2C bus. Moreover, the aforementioned target signal can be the signal generated during the interaction between the BMC and the VR chip.

[0047] In addition, such as Figure 3 As shown, the BMC I2C signal is connected to the CPLD, and then the CPLD sends it to the VR chip on the fan power supply board. The CPLD internally includes the following modules:

[0048] (1) I2C detect module: used to detect whether the BMC is interacting with I2C and to parse the communication data between the BMC and the VR;

[0049] (2) Bypass module and Switch module: used for bidirectional pass-through of BMC I2C data to the backend VR chip;

[0050] (3) I2C Master module (host module): used to access the backend VR chip and obtain the current machine power consumption data.

[0051] (4) I2C slave module: used to parse the fan speed control data sent by the BMC;

[0052] (5) PWM module (Pulse width modulation): It is used to receive the fan speed control data parsed by the I2Cslave module and output the PWM signal to control the fan (FAN) through the output PWM signal (Pulse width modulation signal).

[0053] Step S202: Determine the operating state of the baseboard management controller based on the target signal.

[0054] For example, the status of the BMC can be determined by the changes in signals generated during the interaction between the BMC and the VR chip.

[0055] Step S203: Determine the power-on / off state of the target device based on the operating state of the baseboard management controller.

[0056] For example, determine whether the BMC is in a working state, and if it is, determine whether the server is powered on or powered off. Conversely, if the BMC is determined to be in a non-working state, then determine whether the server is powered on or powered off.

[0057] Step S204: Control the fan speed based on the power-on / off status of the target device.

[0058] For example, it can determine whether the server is powered on or powered off, and if it determines that the server is powered on, it controls the fan to run at a higher speed; if it determines that the server is powered off, it controls the fan to run at a lower speed.

[0059] The above steps solve the problem of using the power-on signal and watchdog timer signal sent by the motherboard to control the fan speed in the device, which increases the number of cables, leading to higher cable costs and lower reliability. By reducing the number of cables, the problem is solved, thereby reducing cable costs and improving device reliability.

[0060] The entities that perform the above steps can be servers, terminals, etc., but are not limited to these.

[0061] In order to quickly and accurately obtain the target signal in the target device, the fan control method provided in this application embodiment can also obtain the target signal in the target device through the following steps: the baseboard management controller interacts with the power conversion chip to obtain the interaction result; based on the interaction result, the target signal in the target device is obtained.

[0062] For example, the Baseboard Management Controller (BMC) on the motherboard of the control server interacts with the VR chip (power conversion chip) on the fan power supply board of the server and obtains the signal generated when the Baseboard Management Controller (BMC) interacts with the VR chip (power conversion chip) (the aforementioned target signal).

[0063] The above method can quickly and accurately obtain the signals generated when the Baseboard Management Controller (BMC) interacts with the VR chip (Power Conversion Chip).

[0064] like Figure 4 As shown, Figure 4 This is a flowchart of a fan control method according to an embodiment of this application. Figure 1 Based on the target signal, the operating state of the baseboard management controller is determined as follows:

[0065] Step S401: Determine the preset time period;

[0066] Step S402: Determine whether the target signal has changed within a preset time period;

[0067] Step S403: If the target signal changes within a preset time period, it indicates that the substrate management controller is in working state.

[0068] Step S404: If the target signal does not change within a preset time period, it indicates that the substrate management controller is in a non-working state.

[0069] For example, within a set time threshold (the aforementioned preset time period), the CPLD I2C detect module detects whether there is a change in the I2C signal (the aforementioned target signal, i.e., the signal generated when the BMC interacts with the VR chip). If the CPLD I2C detect module detects that the I2C signal does not change after the set time threshold has been exceeded, it is determined that the BMC has not completed initialization or the BMC is stuck (the aforementioned substrate management controller BMC is in a non-working state). If the CPLD I2C detect module detects that the I2C signal changes within the set time threshold, it is determined that the BMC is working normally (the aforementioned substrate management controller BMC is in a working state).

[0070] The above scheme utilizes a CPLD to detect BMC I2C data, and the CPLD can quickly and accurately determine the working status of the Baseboard Management Controller (BMC) based on the I2C data.

[0071] like Figure 5 As shown, Figure 5 This is a flowchart of a fan control method according to an embodiment of this application. Figure 2 Based on the operating status of the baseboard management controller, the power-on / off status of the target device is determined, including:

[0072] Step S501: Obtain the current power consumption of the target device based on the operating status of the baseboard management controller;

[0073] Step S502: Determine the power-on / off state of the target device based on its current power consumption.

[0074] For example, based on the operating status of the baseboard management controller, the current power consumption of the server can be obtained in different ways, and based on the obtained current power consumption of the server, it can be determined whether the server is in a powered-on state or a powered-off state.

[0075] Using the above method, the power-on / off status of the machine can be quickly and accurately determined based on the server's current power consumption.

[0076] like Figure 6 As shown, Figure 6 This is a flowchart of a fan control method according to an embodiment of this application. Figure 3 Based on the current power consumption of the target device, the power-on / off state of the target device is determined, including:

[0077] Step S601: Obtain a preset power consumption threshold, wherein the preset power consumption threshold is used to represent the power consumption generated by the target device when it is powered on;

[0078] Step S602: Determine whether the current power consumption of the target device is less than a preset power consumption threshold;

[0079] Step S603: If the current power consumption of the target device is less than the preset power consumption threshold, it means that the target device is in a power-off state.

[0080] Step S604: If the current power consumption of the target device is not less than the preset power consumption threshold, it means that the target device is in the power-on state.

[0081] For example, determine whether the server's actual power consumption is lower than the power-on power consumption threshold (the preset power consumption threshold mentioned above). If the server's actual power consumption is lower than the power-on power consumption threshold, then the server is determined to be in a powered-off state; if the server's actual power consumption is higher than or equal to the power-on power consumption threshold, then the server is determined to be in a powered-on state.

[0082] In summary, CPLD can detect and judge power consumption data in BMC I2C data. That is, by comparing the actual power consumption of the machine with the power-on power consumption threshold, the power-on and power-off status of the machine can be quickly and accurately determined.

[0083] like Figure 7 As shown, Figure 7 This is a flowchart of a fan control method according to an embodiment of this application. Figure 4 Based on the operating status of the baseboard management controller, the current power consumption of the target device is obtained, including:

[0084] Step S701: If the baseboard management controller is in working state, then acquire the communication data between the baseboard management controller and the power conversion chip.

[0085] Step S702: Analyze the communication data between the baseboard management controller and the power conversion chip to obtain the current power consumption of the target device;

[0086] In step S703, if the baseboard management controller is in a non-working state, the power conversion chip is accessed to obtain the current power consumption of the target device.

[0087] For example, when the BMC is working normally, the CPLD uses the Bypass and Switch modules to pass through the BMC I2C to the VR chip. At this time, it's equivalent to a direct I2C connection between the BMC and the VR chip, and the CPLD does not affect their communication. Then, the I2Cdetect module in the CPLD detects the data accessed by the BMC to the VR chip and filters out the actual power consumption data. When the BMC has not completed initialization or is suspended (the aforementioned baseboard management controller BMC is in a non-working state), the I2C connection between the BMC and the VR chip switches to the CPLD's internal I2C master, and the CPLD polls the actual power consumption data in the VR chip.

[0088] Using the above method, the actual power consumption of the machine can be obtained quickly and accurately based on the working status of the Baseboard Management Controller (BMC).

[0089] To quickly and accurately control the fan speed, the fan control method provided in this application embodiment can also control the fan speed through the following steps: if the baseboard management controller is in working state and the target device is in power-on state, then the target data sent by the baseboard management controller is obtained, wherein the target data is used to adjust the fan speed; the fan speed is controlled according to the target data; if the target device is in power-off state, then the fan speed is adjusted to a first speed.

[0090] For example, when the BMC is working normally and the server is powered on, the BMC sends fan speed control data to the CPLD, and the CPLD then controls the fan according to the fan speed control data sent by the BMC. When the BMC is working normally and the server is powered off, the CPLD takes over fan control and adjusts the fan speed to a lower speed (the first speed mentioned above).

[0091] Using the above method, the CPLD can control the fan speed based on the power-on / off status, the BMC's operating status, and the debugging data sent by the BMC.

[0092] In order to quickly and accurately control the fan speed, the fan control method provided in this application embodiment can also control the fan speed through the following steps: parsing the target data to obtain the parsing result; and controlling the fan speed based on the parsing result.

[0093] For example, the CPLD's internal I2C slave module parses the fan speed control data sent by the BMC and controls the fan speed based on the parsed data.

[0094] In summary, by analyzing the fan speed control data sent by the BMC, the fan speed can be easily controlled.

[0095] In order to quickly and accurately control the fan speed, the fan control method provided in this application embodiment can also control the fan speed through the following steps: if the baseboard management controller is in a non-working state and the target device is in a powered-on state, the fan speed is adjusted to a second speed, wherein the second speed is greater than the first speed; if the target device is in a powered-off state, the fan speed is adjusted to the first speed.

[0096] For example, when the BMC has not completed initialization or is stuck (the aforementioned Baseboard Management Controller (BMC) is in a non-working state), different fan speeds can be set according to the server's current power-on / off state. For instance, when the server is powered on, the fan speed is adjusted to a higher speed (the aforementioned second speed); when the server is powered off, the fan speed is adjusted to a lower speed (the aforementioned first speed).

[0097] With the above solution, when the BMC has not completed initialization or the BMC is stuck (the aforementioned baseboard management controller BMC is in a non-working state), the fan speed can be quickly and accurately controlled according to the server's power-on / off status.

[0098] In order to quickly and accurately control the internal temperature of the target device, the fan control method provided in this application embodiment can also control the internal temperature of the target device through the following steps: obtaining the control result of controlling the fan speed; and controlling the internal temperature of the target device based on the control result.

[0099] For example, when the server is powered on, the fan needs to be controlled to run at a higher speed to lower the internal temperature of the server because the server's heat dissipation is poor; when the server is powered off, the server's heat dissipation is better, so the fan needs to be controlled to run at a lower speed to raise the internal temperature of the server.

[0100] The above method can quickly and accurately control the internal temperature of the machine, thereby enabling the server to achieve better heat dissipation.

[0101] The method provided in this embodiment includes, for example, the following steps:

[0102] (1) When the BMC is working normally, the CPLD uses the Bypass module and the Switch module to pass through the BMC I2C to the VR chip. At this time, it is equivalent to the BMC and the VR chip being directly connected through I2C. The CPLD does not affect the communication between the two.

[0103] (2) The I2C detect module in the CPLD detects the data accessed by the BMC to the VR, filters out the actual power consumption data, and compares it with the set power-on power consumption threshold.

[0104] (3) When the actual power consumption is lower than the power-on power consumption threshold, the machine is judged to be in the off state and the CPLD takes over the fan control; when the actual power consumption is higher than the power-on power consumption threshold, the machine is judged to be in the on state and the CPLD performs fan control according to the fan grouping data sent by the BMC.

[0105] (4) When the CPLD I2C detect module detects that the I2C signal has not changed for more than the set time threshold, it is determined that the BMC has not completed initialization or the BMC is stuck, and the CPLD takes over the fan control. At the same time, the I2C connected to the VR switches to the CPLD's internal I2C master. The CPLD polls the actual power consumption data in the VR to determine the current power-on / off state, and sets different fan speeds according to different power-on / off states;

[0106] (5) When the CPLD I2C detect module detects a change in the I2C signal, it determines that the BMC is working normally, and then jumps back to steps (1), (2), and (3).

[0107] Therefore, a CPLD can be used to detect I2C data and determine the working status of the BMC and the machine's power-on / off state. Simultaneously, fan control can be performed based on the debugging data sent by the BMC. The overall control logic only uses the I2C data signal itself, eliminating the need for power-on and WDT signals from the motherboard, thus achieving a complete fan control solution. This simplifies the connection between the motherboard and the fan power board, saves wiring resources occupied by WDT and power-on signals, thereby reducing cable costs and improving the reliability of machine interconnection.

[0108] In summary, the fan control method provided in this application obtains a target signal from a target device, wherein the target device includes at least a motherboard and a power board. The target signal is generated when the baseboard management controller in the motherboard interacts with the power conversion chip in the power board, and the power board includes at least a power conversion chip and a fan. Based on the target signal, the operating state of the baseboard management controller is determined; based on the operating state of the baseboard management controller, the power-on / off state of the target device is determined; and based on the power-on / off state of the target device, the fan speed is controlled. This solves the problem in related technologies where the fan speed is controlled by the power-on signal and watchdog timer signal sent by the motherboard, leading to an increase in the number of traces, resulting in higher cable costs and lower reliability. By using the signal generated when the baseboard management controller of the motherboard interacts with the power conversion chip of the power board to control the fan speed, the power-on signal and watchdog timer signal sent by the motherboard are no longer used to control the fan speed, thereby reducing the number of traces and achieving the effects of reducing cable costs and improving device reliability.
