In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the method and the device for positioning and protecting the power supply abnormality of the motherboard provided by the embodiment of the invention are mainly based on the BMC, and the power supply abnormality of the motherboard is positioned and protected through the BMC. The main board comprises a main power supply module, a plurality of power supply chips and the like, wherein the main power supply module supplies power to other circuit function modules of the main board through each power supply chip.
Referring to fig. 1, an aspect of the present invention provides a method for positioning and protecting a motherboard power supply abnormality, including:
and S110, monitoring the voltage value of each power supply after the mainboard is powered on.
In the embodiment of the invention, the baseboard management controller BMC is provided with an ADC voltage monitoring module, after the mainboard is powered on, the ADC voltage monitoring module monitors voltage input and output data of each power supply of the mainboard, and the baseboard management controller BMC acquires the voltage value of each power supply of the mainboard through an ADC voltage monitoring interface.
S120, judging whether the voltage value of the power supply is within a preset voltage range, and if not, executing the step S130.
In the embodiment of the invention, the preset voltage range is an upper limit critical value and a lower limit critical value of the voltage which can be set by maintenance personnel and can be used for normal work of each path of power supply of the mainboard. During specific implementation, the baseboard management controller BMC collects input and output voltage values of each power supply of the mainboard in the working process respectively, and maintenance personnel can obtain the upper limit critical value and the lower limit critical value of the voltage of each power supply by analyzing historical data.
S130, locking the circuit function module area related to the power supply, and monitoring the temperature value of each power supply chip in the circuit function module area related to the power supply.
In the embodiment of the invention, when the voltage of the mainboard power supply is abnormal, the temperature of the power supply chip is often overhigh. Therefore, when the voltage of a certain power supply is judged not to be in the preset voltage range, the circuit function module area related to the power supply is locked, and meanwhile, the temperature value of each power supply chip in the circuit function module area related to the power supply is monitored. Specifically, the BMC further includes a temperature monitoring module, the temperature monitoring module monitors working temperature data of each power chip in a circuit function module region associated with the power supply, and the BMC acquires a temperature value of each power chip through an I2C interface.
S140, judging whether the temperature value of the power supply chip is larger than a preset temperature threshold value, and if so, executing the step S150.
In the embodiment of the invention, the preset temperature threshold is a temperature critical value which is set by maintenance personnel and can be used for each power supply chip to normally work. Specifically, the baseboard management controller BMC collects the working temperature values of the power chips in the working process, and the maintenance personnel can obtain the temperature critical values of the power chips by analyzing historical data. The preset temperature threshold may be a certain range, or may be a certain value in a certain range.
And S150, starting a timer for timing, and generating a timing time value.
In the embodiment of the invention, when the power chip is overheated in a short time, the normal work of the power chip is not influenced, so that when the baseboard management controller BMC judges that the temperature value of the power chip is greater than the preset temperature threshold, the timer can be started to time, and the time value is generated according to the time of the timer and is used as the time range standard for judging whether the power chip is abnormal or not. The time value generated by the timer is gradually increased, so the generated timing time value is also increased along with the time value.
For example, after the timer is started to count time, the timer starts to count time from 0, and when the current timing time gradually increases to 3s, the correspondingly generated timing time value also increases to 3s in the process, which is used as a criterion for determining whether the subsequent time value reaches the first preset time threshold.
And S160, judging whether the timing time value reaches a first preset time threshold value, and if so, executing the step S170.
In the embodiment of the invention, the first preset time threshold is a time critical value which is set by maintenance personnel and enables each power supply chip to maintain normal work when the temperature critical value is exceeded. During specific implementation, the baseboard management controller BMC collects time values of each power supply chip for maintaining normal work when the temperature critical value is exceeded in the working process, and maintenance personnel can obtain the time critical value of each power supply chip by analyzing historical data. The first preset time threshold may also be a certain range, or may also be a certain value in a certain range.
And S170, sending a power-down instruction to close the circuit function module related to the power supply.
In the embodiment of the invention, when the baseboard management controller BMC judges that the voltage value of a certain power supply is not in the voltage preset range, and meanwhile, the temperature value of a power supply chip in a circuit function module area associated with the power supply is larger than a preset temperature threshold value and the timing time value reaches a first preset time threshold value, a power-down instruction is sent to close the circuit function module associated with the power supply, so that the condition that the main board chip is damaged when the main board power supply is abnormal is prevented, and the condition that the whole system cannot normally run due to the power-down of a main power supply module is avoided.
As can be seen from the above, the method for positioning and protecting abnormal power supply of a motherboard according to the embodiments of the present invention includes monitoring the voltage value of each power supply after the motherboard is powered on, and determining whether the voltage value of each power supply is within a preset voltage range, if the voltage value of a power supply is not within the preset voltage range, locking the circuit function module region associated with the power supply, monitoring the temperature value of each power chip in the circuit function module region associated with the power supply, and determining whether the temperature value of each power chip is greater than a preset temperature threshold, if the temperature value of a power chip is greater than the preset temperature threshold, starting a timer to perform timing, and generating a timing time value, and when the timing time value reaches the first preset time threshold, sending a power-down command to close the circuit function module associated with the power supply, thereby preventing the motherboard chip from being damaged due to abnormal power supply of the motherboard, meanwhile, the phenomenon that the whole system cannot normally operate due to the fact that the main power supply module is powered off is avoided.
In specific implementation, the BMC may use an AST2500 chip to support IPMI2.0 technology, and provide advanced functions such as ADC voltage and temperature monitoring, remote monitoring, and management functions. The baseboard management controller BMC monitors voltage and temperature of server mainboard key power supplies such as a processor core power supply, a processor PCIE core power supply, a processor DDR module IO power supply, a processor IO power supply, a network controller core power supply, a first DDR4 chip power supply, a second DDR4 chip power supply, a button cell power supply, a PCIE bridge power supply, a USB controller power supply, a 12V power supply, a 5V power supply, a 3.3V standby power supply, a BMC nuclear power voltage power supply and a SATA power supply.
Further, in the above embodiment, before step S110, the method further includes:
s101, monitoring impedance values of all paths of power supplies of the mainboard.
In the embodiment of the invention, the impedance value of each path of power supply of the mainboard is monitored by the external monitoring device, wherein the external monitoring device uses an external independent power supply for supplying power and monitors the direct current impedance to the ground of each path of power supply of the mainboard.
S102, judging whether the impedance value of the power supply is in a preset impedance range, if so, executing a step S103, and if not, executing a step S104.
In the embodiment of the invention, the preset impedance range is an upper limit critical value and a lower limit critical value of impedance of each power supply of the mainboard, which are set by maintenance personnel when the power supplies work normally. When a certain power supply of the mainboard has a short-circuit fault, the direct-current impedance to the ground is close to 0, and when the certain power supply of the mainboard has an open-circuit fault, the direct-current impedance to the ground is close to infinity. Therefore, the maintenance person can set the upper limit threshold value to a value close to infinity and the lower limit threshold value to a value close to 0.
And S103, sending a normal signal of the power supply of the mainboard to electrify the mainboard.
In the embodiment of the invention, when the impedance value of each path of power supply of the mainboard is in the normal impedance range, the fact that each path of power supply of the mainboard has no short circuit or open circuit fault is shown, and at the moment, the external monitoring device outputs the normal signal of the power supply of the mainboard, so that the mainboard is normally powered on.
And S104, sending a mainboard power management control signal to prevent the mainboard from being electrified.
In the embodiment of the invention, when the impedance value of a certain path of power supply of the mainboard is not in the normal impedance range, the short circuit or open circuit fault of the path of power supply of the mainboard is shown, and at the moment, the external monitoring device outputs the power supply management control signal of the mainboard and keeps the power supply management control signal of the mainboard all the time so as to prevent the mainboard from being electrified. Maintenance personnel are required to search and repair short circuit or open circuit faults, and then the external monitoring device is disconnected, so that the mainboard can be powered on. Even if a user forcibly presses the start button, the mainboard cannot be powered on due to the mainboard power management control signal output by the external monitoring device, so that the mainboard and the CPU are protected.
Further, in the above embodiment, the method further includes:
and recording the bit numbers of all power chips in the circuit function module area related to the power supply, and generating a fault log.
In the embodiment of the invention, when the baseboard management controller BMC judges that a certain power supply of the mainboard is abnormal, the bit numbers of all power supply chips in the circuit function module area associated with the power supply are recorded, and a fault log is generated, so that maintenance personnel can conveniently search and repair faults.

and if the temperature value of the power supply chip is judged to be not greater than the preset temperature threshold value, resetting the timing time value, and returning to judge whether the temperature value of each power supply chip is greater than the preset temperature threshold value.
In the embodiment of the invention, if the timing time value does not reach the first preset time threshold, the BMC determines that the temperature value of the power chip is not greater than the preset temperature threshold, that is, the temperature value of the power chip falls below the preset temperature threshold, which indicates that the power chip is overheated only in a short time and does not affect the normal operation of the power chip, at this time, the current timing time value needs to be cleared, and whether the temperature value of each power chip is greater than the preset temperature threshold is continuously monitored, when the temperature value of a certain power chip is determined to be greater than the preset temperature threshold again, the timer is reused, a new timing time value is generated, and then a new round of determination on whether the temperature of each power chip is abnormal is started.
Further, in the foregoing embodiment, if the counted time value does not reach the first preset time threshold, the method further includes:
judging whether the timing time value reaches a second preset time threshold value or not;
and if the timing time value reaches the second preset time threshold value, outputting an early warning signal.
In the embodiment of the invention, when the baseboard management controller BMC judges that the timing time value reaches the second preset time threshold and does not reach the first preset time threshold, the baseboard management controller BMC outputs the early warning signal to remind maintenance personnel to analyze and check each power chip in the circuit function module area related to the power supply in advance, so that the condition that the mainboard chip is damaged is prevented.
Further, in each of the above embodiments, the method further includes:
settings for a voltage preset range, a preset temperature threshold, a first preset time threshold, an impedance preset range, and a second preset time threshold are received.
In the embodiment of the invention, a maintenance worker presets a voltage preset range, a preset temperature threshold, a first preset time threshold and a second preset time threshold in the baseboard management controller BMC, and presets an impedance preset range in an external monitoring device.
