Specific embodiment
In order to make the above objects, features, and advantages of the present application more apparent, with reference to the accompanying drawing and it is specific real Mode is applied to be described in further detail the embodiment of the present application.Firstly, the research background to the application is introduced.
Currently, lack the means of the extrapolation PCIE outer plug-in card power supply of monitor controller in computer memory technical field, with It can not find the exception of PCIE outer plug-in card power supply in time as technical staff.In addition, when monitoring the power circuit of mainboard, usually Only monitoring voltage leads to not that the exception other than voltage is effectively monitored and judged.

Embodiment of the method one:
Referring to Fig. 1, which is the method flow diagram of monitoring PCIE outer plug-in card power supply provided by the embodiments of the present application.
As shown in Figure 1, the method for monitoring PCIE outer plug-in card power supply provided by the embodiments of the present application, comprising:
Step 101: obtaining the actual voltage value and actual current value of the power circuit of PCIE outer plug-in card.
In the present embodiment, power circuit is load circuit power supply.Inventor it has been investigated that, when PCIE outer plug-in card power supply is deposited When abnormal, both actual voltage value and actual current value when power circuit works, at least one can exist abnormal.Cause This, is for the exception for monitoring power supply, actual voltage value and reality when the power circuit that this step obtains PCIE outer plug-in card first works Border current value.
Step 102: the actual voltage value being compared with the theoretical voltage section of the power circuit, obtains voltage Comparison result.
It should be noted that having known that power circuit is normal in advance before the present embodiment monitors PCIE outer plug-in card power supply Theoretical voltage value and theoretical voltage value when work allow sliding scales.According to theoretical voltage value and allow sliding scales, The theoretical voltage section of power circuit can be obtained.That is, when the actual voltage value of power circuit is in theoretical voltage range When interior, it can determine that actual voltage value is normal;And the actual voltage value for working as power circuit exceeds theoretical voltage section, then it can be true Determine actual voltage value exception.For ease of understanding, it is exemplified below.
For example, the theoretical voltage value of power circuit is 1.5V, the sliding scales of allowing of theoretical voltage value are ± 5%, accordingly The lower limit that the theoretical voltage section of power circuit can be calculated is 1.5* (1-5%) V, and the upper limit is 1.5* (1+5%) V, and reason It is [1.425V, 1.575V] by voltage range.
If the actual voltage value that step 101 obtains is 1.6V, that is, exceed theoretical voltage section, then practical electricity can be determined Pressure value is abnormal, and actual voltage value is used as to voltage comparison result extremely;If the actual voltage value that step 101 obtains is 1.4V, i.e., Beyond theoretical voltage section, then actual voltage value exception can also be determined, it is used as voltage to compare knot extremely actual voltage value Fruit;If the actual voltage value that step 101 obtains is 1.52V, i.e., without departing from theoretical voltage section, then virtual voltage can be determined Value is normal, by actual voltage value just frequently as voltage comparison result.
Step 103: according to the voltage comparison result and the actual current value, determining that there are different for the power circuit Often.
Due in the case where normal work, the actual voltage value of power circuit should in theoretical voltage range, therefore, If the voltage comparison result is that the actual voltage value is abnormal, i.e. the actual voltage value of power circuit has exceeded theoretical voltage Section, then it is abnormal to determine that the power circuit exists.
In addition, the actual current value of power circuit is not centainly 0, therefore, if the reality in the case where normal work Border current value is 0, and no matter whether actual voltage value in theoretical voltage range, can be determined according to actual current value: electricity It is co-existed in source circuit and the load circuit breaking at least one.
More than, for the method for monitoring PCIE outer plug-in card power supply provided by the embodiments of the present application, this method obtains PCIE first The actual voltage value and actual current value of the power circuit of outer plug-in card;Thereafter, by the actual voltage value and the power circuit Theoretical voltage section be compared, obtain voltage comparison result;Finally, according to the voltage comparison result and the practical electricity It is abnormal to determine that the power circuit exists for flow valuve.This method by by the actual voltage value of the power circuit of PCIE outer plug-in card with Theoretical voltage section is compared, and determines that actual voltage value and theoretical voltage section whether there is difference, while can also combine The actual current value of power circuit is determined power circuit in the presence of abnormal.Therefore, even if this method actual voltage value just In the case where often, also effective monitoring to the power supply of extrapolation PCIE outer plug-in card can be realized according to actual current value.
In addition, technical staff is in application PCIE outer plug-in card power supply, also it is desirable to the load of power circuit power supply can be monitored Circuit whether there is failure.For this purpose, inventor is based on above method embodiment one, another monitoring PCIE is still further provided The method of outer plug-in card power supply, can be by the measurement to actual current value, and by the ratio of actual current value and theoretical current value Compared with determining the failure of load circuit.With reference to the accompanying drawing, it describes in detail to the embodiment of this method.
