Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a control logic switching method, a device, equipment and a medium, which can realize the noninductive switching of fan control logic when the cooling fan control logic of an edge server fails, and avoid influencing the service of the edge server and users.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
At present, a fan is taken as a core component for air cooling and heat dissipation, and is extremely important for heat dissipation of a server. The current server obtains the temperature value on the main board through the BMC to control the rotating speed of the fan so as to achieve the purpose of heat dissipation. While edge servers are typically used by businesses and specific industrial services, users may come into close proximity with the edge servers during operation of the edge servers and are therefore very sensitive to fan noise. However, when the BMC is firmware upgraded or the BMC fails, the fan may operate at a maximum or fixed speed due to failure of the fan control logic. The fan is very noisy when running at maximum speed, seriously affecting user experience, and running at fixed speed may affect server performance and operation of service due to insufficient heat dissipation. Therefore, the embodiment of the application provides a control logic switching method, which can realize the noninductive switching of the fan control logic when the cooling fan control logic of the edge server fails, and avoid influencing the service of the edge server and users. It should be noted that, the application scenario of the control logic switching method provided in the embodiment of the present application is an edge server, and in this embodiment, the application scenario of the control logic switching method is not limited, and the application scenario can be applied to other scenarios requiring control logic switching of a fan according to specific situations, and according to specific implementation situations.
Specifically, the control logic switching method provided by the application is applied to a single chip microcomputer, the single chip microcomputer can be arranged inside an edge server and can also be arranged outside the edge server, the setting position and the specific type of the single chip microcomputer are not limited, and the control logic switching method is determined according to specific implementation conditions. The substrate management controller, the complex programmable logic device and the singlechip in the edge server are all in communication connection; the baseboard management controller and the complex programmable logic device are respectively connected with the fan. It is understood that the fan is a cooling fan of the edge server.
The baseboard management controller, the BMC, is a specialized service processor that uses sensors to monitor the status of a computer, web server, or other hardware driven device and communicates with the system administrator via separate connection lines. The BMC is part of the intelligent platform control interface (Intelligent Platform Management Interface, IPMI) and is typically contained within a motherboard or main circuit board of the device being monitored. In this embodiment, the edge server has a baseboard management controller built in.
A complex programmable logic device (Complex Programmable Logic Device, CPLD) is a more complex logic element than a programmable logic device (Programmable Logic Device, PLD). A CPLD is a digital integrated circuit in which a user constructs logic functions by himself as required. The basic design method is to use integrated development software platform, using schematic diagram, hardware description language and other methods to generate corresponding target file, and transmitting code to target chip through downloading cable to realize designed digital system. In this embodiment, the edge server is built with a complex programmable logic device.
It should be noted that, in this embodiment, the specific connection modes of the single chip microcomputer, the baseboard management controller and the complex programmable logic device are not limited, and depend on the specific implementation situation. As a preferred embodiment, the three may be connected in an implementation by a bi-directional two-wire synchronous serial bus (Inter-Integrated Circuit, I2C). Among them, the I2C bus is a simple serial bus that requires only two wires to transfer information between devices connected to the bus. Based on the above structure, fig. 1 is a flowchart of a control logic switching method according to an embodiment of the present application. As shown in fig. 1, the method includes:
s10: and acquiring temperature information of the edge server main board.
In specific implementation, the singlechip acquires temperature information of the edge server mainboard through a temperature sensor arranged on the edge server mainboard. It can be understood that in this embodiment, the type of the temperature sensor is not limited, and the connection mode of the temperature sensor and the singlechip is also not limited, which depends on the specific implementation situation.
S11: and controlling the baseboard management controller or the complex programmable logic device to output a driving signal to the fan according to the temperature information so as to drive the fan to dissipate heat.
Further, the singlechip controls the baseboard management controller or the complex programmable logic device to output a driving signal to the fan according to the temperature information so as to drive the fan to dissipate heat.
It should be noted that at the same time, only one of the baseboard management controller and the complex programmable logic device is able to output a drive signal to the fan, the singlechip controls the baseboard management controller to output a driving signal to the fan, or controls the complex programmable logic device to output the driving signal to the fan according to the temperature information. In particular implementations, a default device may be set that outputs the drive signal, such as by a baseboard management controller to the fan. The default device for outputting the driving signal is not limited in this embodiment, and depends on the specific implementation.
In addition, the driving signal is not limited in this embodiment, and may be a pulse width modulation (Pulse Width Modulation, PWM) signal, or may be other signals, depending on the specific implementation.
S12: and judging whether the baseboard management controller or the complex programmable logic device has faults or not. If yes, go to step S13, if not, go to step S14.
Since the device outputting the driving signal may malfunction during the execution of the fan control logic, in order to avoid the failure of the fan control, it is also necessary to determine whether the device malfunctions. Specifically, the singlechip judges whether the baseboard management controller or the complex programmable logic device has faults or not. In this embodiment, a specific manner of determining whether the baseboard management controller or the complex programmable logic device has a fault is not limited, and depends on a specific implementation situation.
S13: the switching complex programmable logic device or baseboard management controller outputs driving signals to the fan to maintain the heat dissipation of the fan.
S14: the current control logic continues to execute and ends.
Finally, when the failure of the baseboard management controller or the complex programmable logic device is confirmed, the complex programmable logic device or the baseboard management controller is switched to output a driving signal to the fan so as to maintain the heat dissipation of the fan. And when the baseboard management controller or the complex programmable logic device is confirmed to fail, continuing to execute the current control logic and ending judgment.
It can be understood that, since only one device can output the driving signal to the fan at the same time, when the baseboard management controller outputs the driving signal and confirms that the baseboard management controller fails, in order to avoid failure of the fan control logic, the singlechip switches the complex programmable logic device to output the driving signal to the fan so as to maintain heat dissipation of the fan. When the complex programmable logic device outputs the driving signal and the fault of the complex programmable logic device is confirmed, in order to avoid the failure of the fan control logic, the singlechip is used for switching the baseboard management controller to output the driving signal to the fan so as to maintain the heat dissipation of the fan. It should be noted that, in the present embodiment, the specific process of switching the complex programmable logic device or the baseboard management controller to output the driving signal to the fan is not limited, and depends on the specific implementation.
In this embodiment, the control logic switching method is applied to the singlechip; the singlechip is in communication connection with the baseboard management controller and the complex programmable logic device in the edge server; the baseboard management controller and the complex programmable logic device are respectively connected with the fan; the method comprises the steps of obtaining temperature information of a main board of an edge server; controlling the baseboard management controller or the complex programmable logic device to output a driving signal to the fan according to the temperature information so as to drive the fan to dissipate heat; judging whether the baseboard management controller or the complex programmable logic device has faults or not; if the failure of the baseboard management controller or the failure of the complex programmable logic device is determined, the complex programmable logic device or the baseboard management controller is switched to output a driving signal to the fan so as to maintain the heat dissipation of the fan. Therefore, the scheme controls two groups of mutually redundant fan control logics respectively formed by the baseboard management controller and the complex programmable logic device through the singlechip, can realize the noninductive switching of the fan control logics when the baseboard management controller or the complex programmable logic device fails, avoids the out-of-control fan rotating speed caused by the failure of the control logics, realizes the reliable control of the fan rotating speed, and ensures the stable and efficient heat dissipation of the edge server.
In order to realize the determination of whether the baseboard management controller or the complex programmable logic device has a fault, on the basis of the foregoing embodiment, as a preferred embodiment, the determining whether the baseboard management controller or the complex programmable logic device has a fault includes:
judging whether a first heartbeat signal transmitted by a baseboard management controller is received or not;
if the first heartbeat signal is received, confirming that the baseboard management controller does not have a fault;
if the first heartbeat signal is not received, confirming that the baseboard management controller fails;
judging whether a second heartbeat signal transmitted by the complex programmable logic device is received or not;
if the second heartbeat signal is received, confirming that the complex programmable logic device does not have a fault;
and if the second heartbeat signal is not received, confirming that the complex programmable logic device fails.
In a specific implementation, the singlechip detects a first heartbeat signal transmitted by the baseboard management controller and a second heartbeat signal transmitted by the complex programmable logic device at the same time. When the first heartbeat signal is not received, the singlechip confirms that the fan control logic of the baseboard management controller is invalid, and the baseboard management controller can be subjected to firmware upgrading or has faults; when the second heartbeat signal is not received, the singlechip confirms that the fan control logic of the complex programmable logic device is invalid, and the complex programmable logic device may be in fault.
It should be noted that, in this embodiment, the specific types of the first heartbeat signal and the second heartbeat signal are not limited, and depend on the specific implementation. As a preferred embodiment, the first and second heartbeat signals may be specifically watchdog (watch) signals. A watchdog is essentially a timer circuit, typically having an input called a "watchdog" and an output, typically connected to a reset terminal of another part, typically a single-chip microcomputer. The function of the watchdog is to periodically check the internal condition of the chip and send a restart signal to the chip once an error occurs. The watchdog command has the highest priority among interrupts of the program. Therefore, in this embodiment, the determination of the failure of the baseboard management controller or the complex programmable logic device can be implemented according to whether the corresponding watchdog signal is received.
In particular, in order to realize the noninductive switching of the fan control logic, it is necessary to ensure the uniformity of the fan rotation speed before and after the switching of the control logic, and correspondingly, it is necessary to maintain the uniformity of the fan control information of the driving signals before and after the switching of the control logic, so as to realize the noninductive switching of the fan control logic. Therefore, on the basis of the above embodiment, as a preferred embodiment, before determining whether the baseboard management controller or the complex programmable logic device has failed, after controlling the baseboard management controller or the complex programmable logic device to output the driving signal to the fan according to the temperature information, the method further includes:
The control complex programmable logic device obtains the fan control information of the driving signal according to a preset period, or the control baseboard management controller obtains the fan control information of the driving signal according to the preset period.
In an implementation, when the fan control logic is executed normally, the fan control information of the driving signal at this time is backed up through the communication connection between the baseboard management controller and the complex programmable logic device.
For example, when the baseboard management controller executes the fan control logic, the complex programmable logic device backs up the fan control information of the driving signal output by the baseboard management controller at this time according to a preset period through the I2C bus with the baseboard management controller. Since the driving signal may be a PWM signal, the corresponding fan control information may be a duty cycle of the PWM signal. It should be noted that the preset period is not limited in this embodiment, and depends on the specific implementation. Preferably, the preset period may be set to 10ms, i.e., the complex programmable logic device acquires and backs up the duty cycle of the current PWM signal every 10 ms.
Correspondingly, as a preferred embodiment, switching the complex programmable logic device or the baseboard management controller to output the driving signal to the fan comprises:
The control complex programmable logic device outputs a driving signal to the fan according to the fan control information, or the control baseboard management controller outputs the driving signal to the fan according to the fan control information.
In a specific implementation, when switching the fan control logic to the complex programmable logic device, the singlechip controls the complex programmable logic device and outputs a driving signal to the fan according to the fan control information backed up before, and the fan control information of the driving signal is the same as the fan control information of the driving signal of the baseboard management controller before at the moment, so that the noninductive switching of the fan control logic is ensured. Similarly, when the fan control logic is switched to the baseboard management controller, the singlechip controls the baseboard management controller to output a driving signal to the fan according to the fan control information backed up before, and the fan control information of the driving signal is the same as the fan control information of the driving signal of the complex programmable logic device before at the moment, so that the noninductive switching of the fan control logic is ensured.
In order to better implement switching of the fan control logic, based on the above embodiments, as a preferred embodiment, switching the complex programmable logic device or the baseboard management controller to output the driving signal to the fan includes:
Controlling the multiplexer to switch the complex programmable logic device or the baseboard management controller to output a driving signal to the fan;
the two input ends of the multiplexer are respectively connected with the baseboard management controller and the complex programmable logic device, the output end of the multiplexer is connected with the fan, and the signal end of the multiplexer is connected with the singlechip.
Fig. 2 is a schematic diagram of a redundancy backup scheme for fan control logic according to an embodiment of the present application. As shown in fig. 2, to better implement the switching of the fan control logic, the cooperation of multiplexers (mux) is also required. It will be appreciated that the multiplexer is built into the edge server.
Specifically, two input ends of the multiplexer are respectively connected with the baseboard management controller and the complex programmable logic device, an output end of the multiplexer is connected with the fan, and a signal end of the multiplexer is connected with the singlechip. In the switching process of the fan control logic, the singlechip controls the multiplexer to output a drive signal from one to another, so that the complex programmable logic device or the baseboard management controller is switched to output the drive signal to the fan. It will be appreciated that the multiplexer in this embodiment is embodied as a 2:1 multiplexer. Thereby realizing more accurate switching of fan control logic.
In order to prompt the user that the fan control logic is changed and the device fails, on the basis of the above embodiment, as a preferred embodiment, after determining the failure of the baseboard management controller or the failure of the complex programmable logic device, the method further includes:
and outputting prompt information of the fault of the baseboard management controller or the fault of the complex programmable logic device.
Specifically, after the failure of the baseboard management controller or the failure of the complex programmable logic device is determined, the prompt information of the failure of the baseboard management controller or the failure of the complex programmable logic device is output, so that a user is prompted that the fan control logic is changed, and meanwhile, the prompt of the failure of the device can be realized, and the user can better grasp the running condition of the current edge server.
Further, as a preferred embodiment, after determining the failure of the baseboard management controller or the failure of the complex programmable logic device, the method further includes:
generating a fault log of the baseboard management controller or a fault log of the complex programmable logic device;
and correspondingly analyzing the fault reasons of the baseboard management controller or the fault reasons of the complex programmable logic device according to the fault logs of the baseboard management controller or the fault logs of the complex programmable logic device.
Specifically, after confirming the fault of the baseboard management controller or the fault of the complex programmable logic device, in order to realize fault analysis, a fault log of the baseboard management controller or a fault log of the complex programmable logic device is specifically generated, and the fault cause of the baseboard management controller or the fault cause of the complex programmable logic device is correspondingly analyzed according to the fault log of the baseboard management controller or the fault log of the complex programmable logic device, so that the fault analysis of the fault device of the edge server is realized, and the safety of the edge server is improved.
