For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart of a power supply control method of a power supply circuit according to the present application.
In the embodiment, the situation that the internet traffic and the data volume are increased drastically along with the arrival of big data, cloud computing and artificial intelligence age is considered, and the computing volume and the computing frequency are increased; in the server, as the amount of data for storage and calculation increases, the carrying pressure of the server becomes larger and the stability of the hard disk is critical for the business of the database. Therefore, it is important to ensure reliable power supply of the server including the hard disk and the computing module.
The power supply circuit of the server is arranged on the main board, and the power supply chip can convert the received voltage and then output the converted voltage to each power utilization module comprising a display module, a communication module, a storage module and the like on the main board so as to supply power for each power utilization module. During normal operation, the server corresponds to the S0 state, and all parts can normally operate; however, in the actual operation process, the filter capacitor is likely to be damaged, such as cracks, so that the temperature of the filter capacitor and a power supply chip nearby the filter capacitor continuously rises, and the server is powered off to enter an S5 state. However, due to the special design in the S5 state, even if the power supply chip still receives the stand-by voltage through the filter capacitor under the condition, the temperature of the filter capacitor still continues to rise, so that the temperature of a main board and the like nearby the filter capacitor also continues to rise, but at this time, the server is already shut down, users and related technicians cannot know the situation in time to take measures naturally, and finally the main board is likely to be burnt out, and if the main board is burnt out slightly, the server cannot be reused, and the whole data center machine room is burnt out seriously, so that serious loss is caused. In order to solve the technical problems, the application provides a power supply control method of a power supply circuit, which effectively avoids the occurrence of the server board burning phenomenon.
The power supply control method of the power supply circuit comprises the steps that a power supply, a controllable switch in the power supply circuit, a filter capacitor and input ends of power supply chips are sequentially connected, output ends of the power supply chips are connected with power utilization modules, PMBUS ends of the power supply chips are connected with a control module, and the power supply control method comprises the following steps:
s11: continuously acquiring the temperature of a power supply chip through a PMBUS end;
specifically, the power supply circuit includes, but is not limited to, a power supply circuit in a server; the specific number of the power supply chips is not particularly limited, and may be one or a plurality of power supply chips, and may be determined according to actual power supply requirements. In practical application, the power supply can be connected with a PSU (Power Supply Unit, power supply management component) and then connected with a subsequent controllable switch.
The control terminal of the controllable switch is connected to the control module, and it is understood that the controllable switch herein includes, but is not limited to, various controllable power electronic devices, such as MOSFET (Metal-Oxide-semiconductor-Field-Effect Transistor) or IGBT (Insulated Gate Bipolar Transistor ), and is not particularly limited herein.
It should be further noted that, as a specific embodiment, the control module herein may specifically include a BMC (Baseboard Management Controller baseboard management controller) and a CPLD (Complex Programmable Logic Device complex programmable logic device), where the CPLD is connected to the BMC, the BMC is connected to a control end of the controllable switch, a PMBUS (Power Management Bus power management bus) end of the power supply chip, and the CPLD is connected to a powergood pin of the power supply chip and a powergood pin of each power utilization module, and is used for monitoring a voltage state of each device connected to the CPLD. The power supply chip internally comprises a temperature measuring module capable of determining the temperature of the power supply chip in real time and storing the measured temperature into a register of the power supply chip, so that the power supply chip can continuously send the measured temperature to the BMC through a PMBUS end connected with the BMC, and real-time monitoring is realized.
In addition, the power module herein includes, but is not limited to, a display module (such as a display screen), a storage module (such as a RAID disk, a SATA disk, etc.), a communication module, etc., which are not particularly limited herein. And if the power supply circuit of the original server comprises a voltage conversion chip for providing a power supply reference voltage for the power supply chip, and the voltage conversion chip is connected to the position of the controllable switch, the controllable switch can be replaced by the voltage conversion chip, that is, the execution logic for controlling the controllable switch to be turned on to be turned off can be replaced by controlling the voltage conversion chip to be turned off.
S12: judging whether the temperature of the power supply chip exceeds a preset adjustable temperature threshold value or not; if yes, enter S13;
it should be noted that, the preset temperature-adjustable threshold is set by a technician according to actual requirements, for example, the temperature can be 90 ℃, and in addition, if some power supply chips have own over-temperature power-off threshold, the preset temperature-adjustable threshold should be smaller than the over-temperature power-off threshold so as to realize early warning of board burning danger caused by the power supply chips.
S13: the power supply chip is controlled to cut off the output of each power utilization module;
specifically, when the power supply chip turns off its own output, each power consumption module starts to orderly power down, at this time, the working state of the server is switched from the S0 state to the S5 state, and the step S14 is entered to realize the segmented power-off.
S14: judging whether a power-off state signal which is sent by each power-on module and represents that the power of the power-on module is off or not is received; if the power-off state signal is received, entering S15;
specifically, taking the control module including the BMC and the CPLD as an example, the foregoing steps may be that the BMC determines whether information from the transmission of the CPLD is received, where the information is a power-off state signal (i.e., a level of a powergood pin is converted from a high level signal in a normal working state to a low level signal indicating that the power-off module itself is in a power-off state) received by the CPLD connected to each power-using module, and then the CPLD forwards the power-off state signal to the BMC.
S15: the controllable switch is controlled to be turned from on to off so as to cut off the voltage input of the power supply.
It should be noted that, after the temperature of the power supply chip exceeds the preset adjustable temperature threshold, the controllable switch may be directly controlled to switch from on to off so as to cut off the voltage input of the power supply, but from practical application, the sudden power failure risks causing damage to each power utilization module.
In summary, the application provides a power supply control method of a power supply circuit, a control module is connected with a PMBUS end of a power supply chip, the temperature of the power supply chip can be continuously monitored and obtained, a preset temperature-adjustable threshold value which is adjusted according to the needs of a user is set, and a controllable switch is kept on in a normal state so that the power supply chip supplies power to each power utilization module. Therefore, by establishing the dual judgment logic, each part in the server can be controlled to be orderly and reliably powered off, the voltage input of an external power supply can be reliably and timely cut off under different scenes, the occurrence of burning of a board is avoided, and the operation reliability, maintainability and product competitiveness of the server are improved.
Based on the above embodiments:
as a preferred embodiment, the continuous acquisition of the temperature of the power supply chip through the PMBUS terminal includes:
receiving binary data representing the actual temperature of the power supply chip, which is sent by the power supply chip through a PMBUS end;
converting the binary data to a conversion temperature;
before controlling the power supply chip to turn off the output of each power utilization module, the method further comprises the following steps:
reading binary data stored in a register in a power supply chip;
converting the binary data into a check temperature;
judging whether the check temperature is consistent with the conversion temperature;
if not, recording the result of the inconsistent checking temperature and the conversion temperature into a memory.
In this embodiment, the inventor further considers that there is a possibility of error in the process of data transmission, and thus it is necessary to perform data transmission verification. Specifically, the PMBUS end of the power supply chip transmits actually binary data, and for the same binary data, due to the reasons of system transmission clock setting and the like, a situation of missing transmission of a certain bit of the binary data may exist during transmission, so that an error occurs when the binary data is analyzed into temperature; furthermore, the program code is also in the situation of bug when running actually, so that even for the same binary data and the same preset data-temperature conversion relation, the temperature obtained after the program code analysis is applied may be different.
Then, aiming at binary data (corresponding, the moment at the moment is the first signal transmission moment) which is sent by the PMBUS end and represents the actual temperature of the power supply chip; and converting the binary data into conversion temperature, and then directly taking the conversion temperature as a judging reference to control whether the power supply chip is controlled to turn off the output of each power utilization module or not so as to ensure that the safety of the main board of the server can be prioritized no matter whether the analysis is wrong or not. However, in order to determine whether the shutdown output of the power supply chip has the problem of false shutdown, the temperature data stored in the register in the power supply chip (that is, the binary data and the corresponding time at the moment are the second signal transmission time) can be actively read, the binary data is converted into the verification temperature, and when the verification temperature is inconsistent with the conversion temperature, the problem of false shutdown of the power supply chip at the moment is determined and recorded for subsequent technical research personnel to check. It will be appreciated that when the verification temperature is consistent with the transition temperature, the results of the verification temperature consistent with the transition temperature may also be recorded to the memory for subsequent verification analysis.
It should be noted that, as an extension, the technician may write two sets of program scripts with different specific running codes, namely, a first conversion program script and a second conversion program script, for the binary data representing the actual temperature of the power supply chip, which is sent by the power supply chip through the PMBUS end, according to the coding habit and the preset data-temperature conversion relationship, if the codes have no problem, the first conversion temperature can be obtained according to the conversion of the first conversion program script, the second conversion temperature can be obtained according to the conversion of the second conversion program script, and the two conversion temperatures should be the same, so that when the first conversion temperature is the same as the second conversion temperature, the code error phenomenon described above does not exist, otherwise, the result that the first conversion temperature is inconsistent with the second conversion temperature can be recorded into the memory for subsequent inspection and analysis, and the method is not particularly limited herein.
As a preferred embodiment, determining whether the temperature of the power supply chip exceeds a preset adjustable temperature threshold includes:
judging whether the temperature of the power supply chip exceeds a preset adjustable temperature threshold value for N times continuously and the ith temperature is not more than the (i+1) th temperature, wherein i is not less than 1 and not more than N, i is an integer, and N is an integer not less than 2.
In this embodiment, in order to be closer to practical application and minimize power failure error processing, so as to cause frequent power failure of the server, execution logic for determining whether the temperature of the power supply chip exceeds a preset adjustable temperature threshold is provided, where the execution logic may simultaneously satisfy: the temperature of the power supply chip continuously exceeds the preset adjustable temperature threshold value for N times (it is to be noted that N is not particularly limited, and may be set according to actual requirements, for example, 10 times), and the i-th temperature is not greater than the i+1th temperature, so as to ensure that measures should be immediately taken to prevent board burning when the temperature of the power supply chip is gradually increased. Of course, if the temperature of the power supply chip does not continuously exceed the preset adjustable temperature threshold for N times or the ith temperature of the power supply chip is not greater than the (i+1) th temperature, continuous monitoring is only needed.
As a preferred embodiment, further comprising:
when receiving fault signals representing that the power supply chip has turned off the output of each power utilization module, judging whether a state marking signal representing that the server is in an S5 state and transmitted by the server state monitoring module is received or not;
if yes, the controllable switch is controlled to be turned from on to off.
In this embodiment, the inventor further considers that when the server actually monitors the status of each power module and each power supply chip, a situation of false alarm may occur due to signal transmission errors. In order to solve the problem, taking the control module as an example, the CPLD and the BMC specifically take the CPLD as described above, when the CPLD receives a fault signal sent by the power supply chip and indicating that the power supply chip has turned off the output to each power consumption module (i.e., the powergood pin is converted from a high level signal in a normal output state to a low level signal), the fault signal is transferred to the BMC for monitoring processing.
However, considering that there is a possibility of false alarm due to the fault signal (i.e. the power supply chip may still normally supply power to each power module, but for some reasons, the level signal of its own powergood pin becomes low at a certain moment, but is determined to be a fault signal by the CPLD by misjudgment of the level determination logic in the CPLD as a low level signal at the moment, and is forwarded to the BMC), when the fault signal is received, the BMC determines whether a state flag signal indicating that the server is in the S5 state is received, which is sent by the server state monitoring module connected with the fault signal (specifically, because the data transmission channel connected between the server state monitoring modules is a GPIO bus, the transmission reliability is high), if the fault signal is not actually false alarm, the controllable switch is turned off from on to off to cut off the voltage input of the external power supply, so as to avoid further occurrence of faults such as burn-in.
Therefore, the execution logic reliably ensures that the server is determined to enter the S5 state and then cuts off the voltage input of the external power supply, effectively avoids the situation of frequent shutdown of the server caused by false alarm of fault signals, and has stronger practicability.
As a preferred embodiment, before determining that the status flag signal is received and controlling the controllable switch to turn from on to off, the method further comprises:
acquiring and recording historical information stored in a register of a power supply chip within a preset historical time, wherein the historical information comprises historical temperature information, historical output voltage information and historical output current information;
and determining the reason that the power supply chip turns off the output of each power utilization module according to the historical information and the stored historical state information of each power utilization device in the preset historical time.
In this embodiment, in order to facilitate the subsequent technical developer to grasp the fault situation and analyze the fault situation, taking the control module including the CPLD and the BMC as described above as an example, when it is determined that the S5 state flag signal is received, before the controllable switch is controlled to turn from on to off, the BMC first obtains the history information stored in the register of the power supply chip within the preset history period through the connection line between the BMC and the PMBUS end of the power supply chip, and records the history information, where the preset history period is set according to the common requirement when the technical developer actually analyzes the cause of the fault; and the historical information includes, but is not limited to, historical temperature, historical output voltage, and historical output current of the power chip. The CPLD stores historical state information (the historical state information can be the level state of the powergood pin of each monitored power utilization module) of each power utilization module in a preset historical time period, and the historical state information can be sent to the BMC so as to study and analyze the reason that the power supply chip turns off the power utilization module.
Specifically, the BMC may determine that a power failure abnormality exists in a corresponding power utilization module according to a level state of a powergood pin of each power utilization module within a preset history period, if a monitoring signal of a certain power utilization module is converted from a high level signal to a low level signal, so that a technician can find the power failure abnormality in time; aiming at the obtained historical temperatures of the power supply chip in the preset historical time, based on each historical temperature and the preset temperature-adjustable threshold value, whether the power supply chip has over-temperature or not can be determined, and then the reason for turning off output of the power supply chip is determined to be over-temperature; for the recorded historical output voltage of the power supply chip in the preset historical time, whether the power supply chip has overvoltage or not can be determined, and then the reason for turning off the output is determined to be overvoltage; for the recorded historical output current of the power supply chip in the preset historical time, whether the current exists in the power supply chip or not can be determined, and then the reason for turning off the output is determined to be the current. Therefore, the logic recorded and stored can be convenient for subsequent technical research personnel to grasp the situation.
As a preferred embodiment, further comprising:
when the state flag signal is not received, the result that the fault signal received at this time is misinformation is recorded into a memory.
