Description

Technical Field

[0001] The present application relates to the technical field of switch time management, and in particular to a time management method, device, electronic device and storage medium. Background Art

[0002] With the development of computer technology, the application of centralized monitoring and management technology of switches is becoming more and more widespread in practice. One of the important functions of BMC (Baseboard Management Controller) is to monitor the health status of switch hardware devices and various events that occur in real time (such as operation events of maintenance personnel, such as plugging and unplugging nodes, plugging and unplugging fans, and turning off power, etc.). Once a hardware device fails or the operator performs certain operations, the switch will record it in real time through logs.

[0003] At present, logging is a function that most intelligent products need to have, and system time management is a must for this function. The time management system can provide stable time for the switch system. Development and maintenance personnel need to know the status of the system at any time, so as to analyze the system status later, which is conducive to the analysis and location of system problems and their resolution. The log records contain the events that occurred and the time when the events occurred. The equipment room operation and maintenance managers can use the logs to quickly determine the damaged hardware equipment and time, so as to carry out necessary processing and ensure the safe and stable operation of the entire system. When the switch system is in normal operation or failure state, the system has the function of monitoring and recording various operating parameters of the entire switch, and the timestamp needs to be bound to the system status, which helps the development and maintenance personnel to better analyze.

[0004] If the system time is inaccurate, the recorded fault time and event occurrence time will also be incorrect, and it will be difficult for the operation and maintenance personnel to accurately determine the exact time when the fault occurred and to carry out necessary processing in a targeted manner. In the process of switch time management in the prior art, the accuracy of the system time is often affected by abnormal conditions such as external environmental factors and system power outages. If the BMC time is incorrect, the fault time and event occurrence time recorded in the log will also be incorrect, and it will be difficult for the operation and maintenance personnel to accurately determine the exact time when the fault occurred and to carry out necessary processing in a targeted manner, thereby affecting the reliability of the equipment. Therefore, how to ensure the correctness of the BMC time and ensure that the fault log time is accurate so that the fault can be handled promptly and effectively is an urgent problem to be solved.

[0042] Embodiment 1

[0043] This application provides a time management method, referring to Figure 1 ,include:

[0044] S1, in response to the system being powered on, the baseboard management controller acquires time information generated by the real-time clock generation unit in real time;

[0045] S2, the baseboard management controller calibrates the system time in real time according to the time information;

[0046] S3. In response to detecting that the system operating state is abnormal, switching to the backup power circuit to supply power to the real-time clock generation unit to maintain normal operation of the real-time clock generation unit.

[0047] Specifically, refer to Figure 2 The system includes a main power supply unit, a backup power supply unit, a field effect transistor switch unit and a complex programmable logic device control unit. Among them, the field effect transistor (Metal-Oxide-Semiconductor Field-EffectTransistor, MOSFET) switch unit is used for switch control of the main power supply unit and the backup power supply unit. The field effect transistor switch unit is also used to receive instructions from the complex programmable logic device control unit so that the baseboard management controller can read the main power supply voltage of the main power supply unit and the backup power supply voltage of the backup power supply unit. The output end of the main power supply unit is connected to the first power supply end of the real-time clock generation unit, and the output end of the backup power supply unit is connected to the second power supply end of the real-time clock generation unit. The field effect transistor switch unit also includes a first field effect transistor switch unit and a second field effect transistor switch unit. The first field effect transistor switch unit is used for switch control of the main power supply unit, and the second field effect transistor switch unit is used for switch control of the backup power supply unit. The output end of the main power supply unit is connected to the input end of the first field effect transistor switch unit, the output end of the backup power supply unit is connected to the input end of the second field effect transistor switch unit, and the output end of the first field effect transistor switch unit, the output end of the second field effect transistor switch unit and the output end of the real-time clock generation unit are connected to the baseboard management controller.

[0048] In some embodiments, the system further includes a diode dual-path gating unit, the output end of the main power supply unit is connected to the first input end of the diode dual-path gating unit, the output end of the standby power supply unit is connected to the second input end of the diode dual-path gating unit, and the output end of the diode dual-path gating unit is connected to the baseboard management controller. The diode dual-path gating unit is used to perform diode gating according to the main power supply voltage and the standby power supply voltage, so that the baseboard management controller obtains the working information of the main power supply unit and the standby power supply unit in real time.

[0049] Specifically, the main power supply unit includes an AC-DC conversion module and a DC-DC conversion module, which provide stable and reliable power for modules such as a complex programmable logic device control unit, a field effect transistor MOS switch unit, a baseboard management controller, and a diode dual-path gating unit. The built-in AD module measurement function of the baseboard management controller can realize real-time monitoring of the main power supply voltage of the main power supply unit and the backup power supply voltage of the backup power supply unit. The complex programmable logic device control unit (Complex Programmable Logic Device, CPLD) is used by the user to operate the serial port tool to input instructions. The CPLD control unit communicates with the baseboard management controller through UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver / Transmitter), and the baseboard management controller controls the stable operation of the entire clock management system. CPLD is widely used in control circuits to achieve the purpose of controlling multiple CPLD online upgrades. CPLD has the advantages of high speed, flexible debugging, and short development cycle. Using CPLD to control devices such as MOS can reduce the operating burden of the BMC unit. Each CPLD device has sufficient input and output pins, which can generally meet the design requirements of the switch system. The system has strong scalability, and the CPLD program development is convenient. It can effectively reduce the hardware development cycle and development cost, and has strong universality. The field effect tube MOS switch unit mainly plays the role of switch control and voltage isolation. It receives the instructions of the CPLD control unit and executes the switch action of the corresponding instructions. At the same time, it enables the baseboard management controller to read the main power supply voltage and the backup power supply voltage. The backup power supply unit is used to provide a stable backup power supply to the RTC generation unit to ensure that after the system main power supply unit is powered off, it can also provide uninterrupted power supply to the system to ensure the stability of the system time. The diode dual-path gating unit is used to perform diode gating according to the size of the input 3.3VDC main and backup voltages. This enables the BMC to obtain the current working power supply information of the system and generate log records of the main power supply voltage and the backup power supply voltage inside the BMC, including the corresponding voltage information and time information. This is different from the AD module built into the BMC. The AD module reads the average main power supply voltage and the backup power supply voltage over a period of time through the field effect transistor MOS switch unit; the specific information of the main power supply voltage and the backup power supply voltage at each time point is transmitted to the BAT log module inside the BMC through the diode dual-path selection unit, which can reflect the real-time working power supply status of the main power supply unit and the backup power supply unit for subsequent tracing of information.

[0050] Specifically, the system includes a clock management system for a server or a switch, which controls a real-time clock (RTC) generation unit through a baseboard management controller of the system to generate continuous and accurate time to ensure the correctness of the internal time of the server or the switch, and ensures that the time is accurate and effective for a long time through an uninterrupted power supply mode of a main power supply circuit of a 3.3VDC (Direct Current) main power supply unit or a backup power supply circuit of a backup power supply unit.

[0051] Specifically, when the above-mentioned clock management system is powered on, that is, the clock management system is in normal operation, the baseboard management controller can obtain the time information generated by the RTC generation unit in real time through the I2C bus (Inter-Integrated Circuit, two-wire serial bus), and the time information can be used as the standard time of the system, which can be used for system logging, accurate time display, etc. In addition, the baseboard management controller can read and write the RTC generation unit (RTC clock chip) through the I2C bus to achieve time calibration between systems. In particular, when the system of the server or switch is in a fault or abnormal working state, the real-time clock generation unit can be powered by switching the main power supply circuit and the backup power circuit to maintain the normal operation of the real-time clock generation unit and provide accurate time for the system.

[0052] In some embodiments, S3 includes:

[0053] S31. In response to the baseboard management controller detecting that the main power supply voltage of the main power supply unit is less than a first voltage threshold, the baseboard management controller switches to the backup power circuit to supply power to the real-time clock generation unit through the backup power supply unit to maintain normal operation of the real-time clock generation unit.

[0054] In some embodiments, after S31, the method further comprises:

[0055] S32: In response to the baseboard management controller detecting that the main power supply voltage of the main power supply unit is maintained within the main voltage operating range within the first preset time, the baseboard management controller cuts off the backup power circuit and supplies power to the real-time clock generation unit through the main power supply unit.

[0056] Exemplarily, when the BMC detects that the main power supply voltage is less than the first voltage threshold, for example, the main power supply voltage that should be maintained at 3.3V is less than 3.0V, it can be determined that the main power supply is abnormal. At this time, the baseboard management controller opens the backup power circuit through the field effect transistor MOS switch unit and supplies power to the real-time clock generation unit through the backup power supply unit. In particular, in order to reduce the battery loss of the backup power supply unit, the main power supply voltage can also be monitored within a certain time range. If the main power supply voltage is less than 3.0V for more than a certain frequency, it is determined that the main power supply is abnormal, and the backup power circuit is switched. If the main voltage is subsequently maintained within the operating range within the first preset time (for example, 30 seconds, one minute, etc.), for example, it exceeds 3.0V, the baseboard management controller can cut off the backup power circuit and supply power to the real-time clock generation unit through the main power supply unit.

[0057] In some embodiments, S3 further includes:

[0058] S33. In response to the baseboard management controller detecting that the main power supply voltage of the main power supply unit is greater than the first voltage threshold and less than the second voltage threshold within the second preset time, the baseboard management controller opens the backup power circuit in advance and supplies power to the real-time clock generation unit through the main power supply unit and the backup power supply unit.

[0059] In some embodiments, after S33, the method further includes:

[0060] S34. In response to the baseboard management controller detecting that the main power supply voltage of the main power supply unit is greater than the second voltage threshold within a third preset time, the baseboard management controller turns off the backup power circuit and supplies power to the real-time clock generation unit through the main power supply unit.

[0061] Exemplarily, the clock management system can also perform backup power to reduce clock errors and maintain stable operation of the RTC generation unit. If the baseboard management controller detects that the main power supply voltage of the main power supply unit is greater than the first voltage threshold and less than the second voltage threshold within the second preset time, for example, the main power supply voltage is greater than 3.0V but less than 3.1V within the second preset time, the baseboard management controller can open the backup power circuit in advance to prevent the main power supply unit from suddenly failing and stopping working, and unable to smoothly transition to the backup power circuit for power supply, thereby causing errors. If the main power supply voltage exceeds 3.1V again within the third preset time, the backup power circuit can be turned off through the BMC to reduce battery loss. The above-mentioned first preset time, second preset time and third preset time can be preset with an empirical value, or can be set by the user according to actual business needs or business conditions.

[0062] In some embodiments, the method further comprises:

[0063] 101. The baseboard management controller obtains working information of the main power supply unit and the backup power supply unit in real time;

[0064] 102. The baseboard management controller generates a log record according to the working information, where the log record includes at least one of the record information of the main power supply voltage, the record information of the backup power supply voltage, the fault information of the main power supply unit, and the operation information of the backup power supply unit.

[0065] Specifically, referring to the above description, the diode dual-path gating unit is used to perform diode gating according to the magnitude of the input 3.3VDC main and backup voltages. Thus, the BMC can obtain the working information of the main power supply unit and the backup power supply unit; generate log records of the main power supply voltage and the backup power supply voltage inside the BMC, including the corresponding voltage information and time information, which is different from the AD module built into the BMC. The AD module reads the average main power supply voltage and the backup power supply voltage over a period of time through the field effect tube MOS switch unit; and the specific information of the main power supply voltage and the backup power supply voltage at each time point is transmitted to the BAT log module inside the BMC through the diode dual-path gating unit, which can reflect the real-time working power supply status of the main power supply unit and the backup power supply unit for subsequent tracing of information. The log record includes the recording information of the main power supply voltage, the recording information of the backup power supply voltage, the fault information of the main power supply unit, and the operation information of the backup power supply unit, including the voltage information corresponding to each time point of the main power supply voltage and the backup power supply voltage, the time point information of the backup power circuit opening and closing, etc., which can be used for operation and maintenance operators to trace back later or deal with the fault in time.

[0066] In this embodiment, the baseboard management controller can read the time information generated by the real-time clock generation unit in real time and calibrate the system time in real time. At the same time, the main power supply circuit and the backup power circuit can provide uninterrupted power supply to maintain the normal operation of the real-time clock generation unit, strictly guarantee the accuracy of the system time, ensure the correctness of the hardware equipment failure and operation log recording time of the entire clock management system, so that the development or operation and maintenance operators can effectively handle the failure in time. The baseboard management controller can also monitor the main power supply voltage of the main power supply unit in real time, and execute different power supply strategies according to whether the main power supply voltage is maintained within the normal voltage range, so as to meet the requirements that the time information of the switch equipment can be normal and stable in both normal and abnormal system states, making the system more reliable and highly scalable.

They are only for the convenience of describing the method of the present application, and cannot be understood as indicating the order of the steps.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.
