All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to facilitate understanding of the fault data acquisition method of VR provided in the present application, a system to which the fault data acquisition method of the present application is applicable is described below, referring to fig. 1, which shows a schematic structural diagram of a fault data acquisition system of VR in an embodiment of the present application.

Referring to fig. 1, the fault data acquisition system provided in this embodiment of the present application includes a BMC (Baseboard Management Controller ) 01, a DRAM (Dynamic Random Access Memory, dynamic random access memory) 02, a Flash Rom 03, and a terminal 04, specifically, on a server motherboard, the BMC 01 selects GPIO (General Purpose Input/Output, general purpose input/Output port) and I2C (Inter Integrated Circuit, two-wire serial bus) resources to be abundant, and processing performance is dominant, such as a BMC 01 chip with a model of AST2500, a DRAM 02 connected to the BMC 01 selects DDR4 to store particles, specifically selects a chip with a model of H5AN4G6NBJR-VKC, and a Flash Rom 03 connected to the BMC 01, specifically, may select a Rom memory chip with a model of ACA-SPI-006-K01. The I2C interface of the target VR is interconnected with the I2C interface of the BMC 01, the fault# signal pin of the target VR is interconnected with the GPIO pin of the BMC 01, the Fault trigger signal of the BMC 01 is interconnected with the CS# of the Flash chip, the SPI interface of the BMC 01 is interconnected with the Flash chip, the data bus of the BMC 01 is interconnected with the data bus of the DRAM 02, the BMC 01 is interconnected with the network of the terminal 04 through an RJ45 connector to realize the IPMI (Intelligent Platform Management Interface ) interface, so that a user can log in the web interface through the terminal 04 to check the working state and the working signal waveform of the machine.

The fault data acquisition method of the VR provided by the present application may be specifically implemented by the BMC, and the fault data acquisition method provided by the present application is described in detail below.

Referring to fig. 2, fig. 2 is a flowchart of steps of a fault data obtaining method of VR provided in the present application, where the fault data obtaining method includes:

s101: storing the obtained associated data corresponding to each working signal of the target VR into a DRAM;

specifically, the I2C interface of the target VR is interconnected with the I2C interface of the BMC, the BMC can simultaneously acquire the associated data of each working signal of the target VR through the I2C interface, the defect that a single oscilloscope can only grasp 4 paths of signals in the prior art is overcome, and the comprehensiveness and the reliability of the scheme are improved. All the obtained association data is then saved to the DRAM for subsequent retrieval from the DRAM upon triggering of the target VR failure. It can be understood that the DRAM is a dynamic random access memory, and the associated data is temporarily stored in the DRAM first, so that the subsequent response speed of calling can be improved, and the current associated data can be stored in Flash Rom in time when the target VR fault is triggered, so that the current associated data can be checked by staff. The operation signal of the target VR includes an input voltage signal VIN and/or an enable signal EN and/or a Power Good signal and/or an output voltage signal VOUT and/or an output current signal IOUT and/or a temperature signal TEMP, where the Power Good signal indicates that the output voltage has normally established an output.

In this embodiment, the association data corresponding to each working signal of the obtained target VR may be stored in the DRAM according to a preset time period, or the association data corresponding to each working signal of the obtained target VR may be stored in the DRAM after the temporary storage signal is received, where a trigger condition for storing the association data corresponding to each working signal of the obtained target VR in the DRAM is not limited.

S102: when a fault trigger signal sent by a target VR is received, all relevant data in the DRAM are transferred to a Flash Rom;

specifically, the target VR generates a Fault trigger signal fault# under the Fault conditions of overvoltage and/or overcurrent and/or overtemperature, and the fault# signal pin of the target VR is interconnected with the GPIO pin of the BMC, so that when the target VR triggers any Fault condition, the Fault trigger signal is sent to the BMC through the fault# signal pin, in order to avoid that the machine is down or power down due to the influence of the Fault of the target VR, the data in the DRAM disappears to influence the subsequent analysis of the associated data, and in the embodiment, the BMC generates a cs# signal after receiving the Fault trigger signal sent by the target VR, controls the chip selection of Flash Rom to be effective, and transfers all the temporarily stored associated data in the DRAM into the Flash Rom, namely, automatically saves the field data during Fault triggering, and after the machine is down or power down, the associated data in the Flash Rom cannot disappear, so that the subsequent user can call through the terminal.

S1013: and determining fault data of the target VR according to all the associated data in the Flash Rom, and accessing the BMC through the terminal to obtain the fault data.

Specifically, all relevant data in Flash Rom are processed to obtain fault data of target VR, such as waveforms of working signals, working states of machines and the like, a user can log in a web interface by using a terminal, and the fault data is read by accessing an IPMI (intelligent platform management interface) of the machines, so that on-site measuring signals of staff are not needed, and timeliness of fault positioning and processing is improved.

Therefore, according to the embodiment, all paths of working signals of the target VR are obtained through the BMC which is connected with the target VR, when the fault of the target VR is triggered, the BMC responds to the related data of all the working signals in the DRAM in time and automatically transfers the related data to the Flash Rom, so that the related data of all the working signals are not disappeared after the server is abnormally powered down, the analysis of subsequent staff is facilitated, the reliability of the scheme is improved, and the staff can access the BMC through the terminal to obtain and analyze the fault data in the Flash Rom without capturing the signal waveform when the fault occurs on site through the oscilloscope, so that the labor cost is reduced, and the timeliness of fault positioning is improved.

Based on the above embodiments:

as a preferred embodiment, the process of saving the obtained association data corresponding to each working signal of the target VR in the DRAM specifically includes:

acquiring associated data corresponding to each working signal of the target VR according to the acquisition period;

determining target associated data corresponding to each working signal, and storing all target associated data into a DRAM according to a storage period;

the target associated data corresponding to each working signal are as follows:

in a storage period, an average value of all associated data corresponding to the working signal;

or in the storage period, the same number of the associated data exceeding a preset value is adopted in all the associated data corresponding to the working signal, and the acquisition period is smaller than the storage period.

Specifically, in this embodiment, the association data corresponding to each working signal of the target VR may be obtained according to the acquisition period, and then the target association data is written into the DRAM according to the second preset period. In order to avoid misoperation and misjudgment, preprocessing operation is carried out on the associated data stored in the DRAM in consideration of the fact that interference signals possibly are coupled to the I2C signal line. The preprocessing operation is described by taking the Power Good signal as an example: and determining the associated data, of which the same number exceeds a preset value, in all the associated data acquired in the second preset period as target associated data of the Power Good signal, which is required to be stored in the DRAM at present, as associated data corresponding to the Power Good signal, namely high-level data or low-level data. Assuming that the acquisition period is 1s, the storage period is 5s, the preset value is 3, 5 associated data can be obtained in 5s, if 1,1,1,0,1 is respectively obtained, the associated data with the same number exceeding the preset value is 1, and the 1 is stored into the DRAM as the target associated data of the current storage period. The preprocessing operation will be described by taking the VOUT signal as an example: the relevant data corresponding to the VOUT signal, namely specific voltage data, is obtained by averaging all relevant data acquired in the storage period, and the average value is determined as target relevant data which needs to be stored in the DRAM in the current storage period of the VOUT signal.

Specifically, in order to improve the acquisition efficiency, in this embodiment, the associated data is stored in the DRAM in a refreshing manner, that is, all the associated data obtained in the current storage period replace the associated data stored in the DRAM in the previous storage period, so that only the associated data in the current storage period are stored in the DRAM, on one hand, the space occupied by the associated data in the DRAM can be reduced, and on the other hand, when the target VR fault is triggered, all the associated data stored in the Flash Rom from the DRAM is the associated data near the triggering time of the target VR fault, so that the actual working condition is more satisfied, and the accuracy of acquiring the fault data is improved.

Of course, the associated data corresponding to each storage period can be stored in the DRAM, and after the target VR fault is triggered, the last stored data is selected and transferred to the Flash Rom.
