Referring to fig. 1, the fault data acquiring system provided in the embodiment of the present application includes a BMC (baseboard management Controller) 01, a DRAM (Dynamic Random Access Memory) 02, a Flash Rom 03, and a terminal 04, and specifically, on a server motherboard, the BMC 01 may use GPIO (General Purpose Input/Output) and I2C (Inter integrated circuit, two-wire serial bus) which have abundant resources and excellent processing performance, such as a BMC 01 chip with AN AST2500 model, a DRAM 02 connected to the BMC 01, a BMC 4 Memory particle, specifically a BMC chip with a model H5AN4G6NBJR-VKC, a Flash Rom 03 connected to the BMC 01, and specifically AN ACA-SPI-006-Rom 01.

The VR fault data acquisition method provided by the present application may be specifically implemented by a 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 illustrating steps of a method for acquiring fault data of a VR according to the present application, where the method includes:

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

specifically, an I2C interface of the target VR is interconnected with an I2C interface of the BMC, and the BMC can simultaneously acquire associated data of each working signal of the target VR through the I2C interface, so that the defect that a single oscilloscope can only capture 4 paths of signals in the prior art is overcome, and the comprehensiveness and reliability of the scheme are improved. And then all the acquired associated data are saved in the DRAM so as to be called from the DRAM subsequently when the target VR triggers the fault. It can be understood that the DRAM is a dynamic random access memory, and the associated data is firstly temporarily stored in the DRAM, so that the subsequent calling response speed can be improved, and the current associated data can be timely stored in the Flash Rom when the target VR fault is triggered, so that a worker can conveniently check the data. The operating 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, and the Power Good signal indicates that the output voltage has normally established an output.

In this embodiment, the associated 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 associated 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 the trigger condition for storing the associated 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 working condition of overvoltage and/or overcurrent and/or overtemperature, a Fault # signal pin of the target VR is interconnected with a GPIO pin of the BMC, therefore, when the target VR triggers any Fault working condition, the Fault trigger signal is sent to the BMC through the Fault # signal pin, in order to avoid the machine from being down or powered down under the influence of the Fault of the target VR, the disappearance of data in the DRAM affects the subsequent analysis of the associated data, and it is considered that, in this embodiment, the BMC generates a CS # signal after receiving a fault trigger signal sent by the target VR, controls the chip selection of the Flash Rom to be effective, transfers all relevant data temporarily stored in the DRAM to the Flash Rom, the method is characterized in that field data when a fault is triggered is automatically stored, and after a machine is powered off or crashed, associated data in the Flash Rom cannot disappear, so that a subsequent user can call the data through a terminal.

S1013: and determining fault data of the target VR according to all relevant data in the Flash Rom so as to obtain the fault data by accessing the BMC through the terminal.

Specifically, all relevant data in the Flash Rom are processed to obtain fault data of the target VR, such as waveforms of all working signals and working states of the machine, a user can log in a web interface by using a terminal and read the fault data by accessing an IPMI interface of the machine, a worker does not need to measure the signals on site, and the timeliness of fault location and processing is improved.

It can be seen that, in this embodiment, each path of working signal of the target VR is simultaneously acquired by the BMC interconnected with the target VR, when the target VR is triggered due to a fault, the BMC timely responds to automatically transfer the associated data of all the working signals in the DRAM to the Flash Rom, so as to ensure that the associated data of all the working signals does not disappear after the server is abnormally powered down, thereby facilitating the analysis of subsequent workers, improving the reliability of the scheme, and the workers can access the BMC through the terminal to acquire and analyze the fault data in the Flash Rom, without grabbing a signal waveform when the fault occurs on site through an oscilloscope, reducing the labor cost, and improving the timeliness of fault location.

On the basis of the above-described embodiment:

as a preferred embodiment, the process of storing the acquired associated data corresponding to each operating signal of the target VR in the DRAM specifically includes:

in a storage period, averaging all relevant data corresponding to the working signal;

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

Specifically, in this embodiment, the associated data corresponding to each working signal of the target VR may be obtained according to the collection period, and then the target associated data is written into the DRAM according to the second preset period. To avoid false operation and misjudgment, the associated data stored in the DRAM is preprocessed to take into account that a disturbing signal may be coupled to the I2C signal line. The preprocessing operation will be described by taking the working signal as a Power Good signal as an example: and determining the relevant data with the same number exceeding the preset value in all relevant data acquired in the second preset period as the target relevant data of the Power Good signal which needs to be stored in the DRAM at present, wherein the relevant data is high-level data or low-level data corresponding to the Power Good signal. Assuming that the acquisition period is 1s, the storage period is 5s, and the preset value is 3, 5 pieces of associated data can be acquired within 5s, if the acquired associated data are 1, 1, 1, 0, and 1 respectively, the associated data with the same number exceeding the preset value are 1, and 1 is stored in the DRAM as the target associated data of the current storage period. The preprocessing operation will be described by taking the working signal as the VOUT signal as an example: and averaging the relevant data corresponding to the VOUT signal, namely the specific voltage data, obtained in the storage period, and determining the average value as target relevant data of the VOUT signal which needs to be stored in the DRAM in the current storage period.

and replacing all the relevant data stored in the DRAM with the currently acquired relevant data corresponding to each working signal of the target VR.

Specifically, in order to improve the acquisition efficiency, in this embodiment, the associated data is stored in the DRAM in a refresh manner, that is, all the associated data obtained in the current storage period are replaced with the associated data stored in the DRAM in the previous storage period, so that only the associated data in the current storage period is 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 a target VR fault is triggered, all the associated data that are transferred from the DRAM to the Flash Rom are the associated data near the target VR fault triggering time, which more meets the actual working condition, and thus the accuracy of acquiring the fault data is improved.

Of course, the associated data corresponding to each storage cycle may also be stored in the DRAM, and when the target VR is triggered by a fault, the last stored data is selected and is transferred to the Flash Rom.
