Detailed description of the invention
The core of the present invention is to provide a kind of power module failure diagnostic method, the method allow users to and
Time according to obtain power module health status information analyze power module failure reason, such that it is able to
Improve the reliability of power module failure diagnosis.
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
Refer to the flow process of the power module failure diagnostic method that Fig. 1, Fig. 1 are provided by the embodiment of the present invention
Figure；The method may include that
S100, health status information to power module detect；
S110, when the health status information described power module being detected changes, record become
The health status information changed is to designated memory space；
Wherein, the normal work of whole equipment can be affected owing to power module breaks down, it is therefore desirable to right
The health status information of power module detects, and detection here can be to carry out in real time, it is also possible to is
Detect according to predetermined period according to the actual requirements, herein for can as far as possible accurately comprehensively obtain
The health status information of power module, the detection cycle should be the shortest, is preferably capable of carrying out in real time.
The particular content of the health status information of detection here can be set according to practical situation, can
Choosing, health status information can include time and the status information that health status information changes.The most also
The particular content of health status information is not defined.
After breaking down due to power module, equipment entirety there will be the situation of power down.In prior art,
The health status information data detected after device looses power can be cleared, and after equipment powers on again, also looks for
Less than health status information, the failure cause being unable to power module occur is analyzed, and then
Not can determine that the failure cause of power module, it is impossible to carry out fault cleaning timely, safety may be there is
Hidden danger.Therefore, the present embodiment can be vertical when health status information power module being detected changes
Engrave and record the health status information changed to designated memory space, designated memory space right and wrong here
Non-volatile data memory space in volatile data storage space, e.g. power module, it is also possible to refer to
The non-volatile data memory space of fixed other positions of equipment.Preferably, the healthy shape changed is recorded
State information is in described power module non-volatile data memory space.So can be rapidly performed by storage,
And need not the miscellaneous part in equipment is made a change, more convenient fast.
S120, when receiving reading instruction, export the health status of storage in described designated memory space
Information.
Wherein, when equipment recovers normal, instruction can be read by sending, obtain designated memory space
The health status information of interior storage；Health status information is utilized power failure reason to be carried out in time,
Analyze reliably.
Utilize whole machine cabinet server power block Off-line faults diagnosis, as specific embodiment, the method is described
Concrete processing procedure:
After the power module FW of whole machine cabinet server detects that power module health status exists extremely,
The data of the health status of power module are saved in power module non-volatile data memory space.So
After whole machine cabinet server power supply lost efficacy, the fault in-situ of power module can preserve.Whole machine cabinet services
After device power down, monitoring management module provides the side reading power module non-volatile data memory space record
Method, reads power module non-volatile data memory space data, such that it is able to carry out the event of power module
The analysis of barrier reason and fault diagnosis.
Based on technique scheme, the power module failure diagnostic method that the embodiment of the present invention provides, it is possible to
Obtain power module break down time health status information, allow users to according to obtain power supply mould
The health status information of block analyzes the reason of power module failure, examines such that it is able to improve power module failure
Disconnected reliability, accuracy；Prevent and prior art fails obtain fault data, thus can not obtain
Situation to failure cause；User can also be according to the shape of the information prediction power module got further
State, prevents power failure.
Above-described embodiment records the health status information changed to designated memory space, finger here
If it is very big to determine memory space, then need not the mistake relating to that the data in designated memory space are cleared up
Journey, but once this designated memory space size is limited, then have to periodically or every time to appointment deposit
Data in storage space are cleared up；Such as non-volatile data storage size in power module is limited,
It would therefore be desirable to have certain data scrubbing mechanism；Optionally, the health status letter that described record changes
Breath may include that to designated memory space
Judge whether designated memory space is full；
If, it is determined that the health status information that write time in described designated memory space is the longest, and
By the health status information the longest described health status information the changed covering said write time.
Wherein, it is that the storage time according to the state of health data in designated memory space is for according to entering here
The replacement of the new legacy data of row.Such as definition power module log recording mechanism i.e. PSU module FW log note
The mechanism of record, after log is full, circulates and covers from Article 1 log.
Optionally, it is also possible to this health status information can be deleted after output health status information every time,
Because breaking down next time, it doesn't matter with these data again, and these data have exported, even if
For the prediction of power module be have also already been output record.Therefore, it can exporting described appointment
In memory space after the health status information of storage, delete the healthy shape of output in described designated memory space
State information.
Based on technique scheme, the power module failure diagnostic method that the embodiment of the present invention provides, it is possible to
Obtain power module break down time health status information, allow users to according to obtain power supply mould
The health status information of block analyzes the reason of power module failure, examines such that it is able to improve power module failure
Disconnected reliability, accuracy；Prevent and prior art fails obtain fault data, thus can not obtain
Situation to failure cause；User can also be according to the shape of the information prediction power module got further
State, prevents power failure；Appointment can be improved by the data dump process of designated memory space to deposit
The utilization rate in storage space, completes the record health status of this embodiment with the least memory space resource
The task of information.
Embodiments provide power module failure diagnostic method, allow users in time according to acquisition
Power module health status information analyze power module failure reason.
The power module and the whole machine cabinet server that there is provided the embodiment of the present invention below are introduced, and hereafter retouch
Power module and the whole machine cabinet server stated can be the most right with above-described power module failure diagnostic method
Should refer to.
Refer to the structured flowchart of the power module that Fig. 2, Fig. 2 are provided by the embodiment of the present invention；This power supply
