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
