Transmitting element 314；The detector 311 includes voltage sensor 311a, current sensor 311b and power sensor 311c；The spy
Device 311 is surveyed to be used to obtain the running parameter at power supply interface in real time；The power supply that above-mentioned comparator 312 is used to obtain more in real time connects
Whether the running parameter at mouthful exceeds default scope；The running parameter that above-mentioned counter 313 is used at power supply interface exceeds
Counted during default scope, corresponding to running parameter and add one；Above-mentioned signal transmitting unit 314 is by working as based on corresponding to running parameter
When number exceedes preset value, fault pre-alarming signal is sent to peripheral control unit.
Generally, before power supply group breaks down, the running parameter at its power supply interface may fluctuate, but the ripple
Dynamic is probably that normality caused by external power source fluctuates, it is also possible to which circuit caused by aging occurs for power supply group internal component not
Fluctuated caused by stable；If normality caused by external power source fluctuates, its frequency is relatively low, may only occur once；Such as
Fruit is that power supply group internal component occurs to fluctuate caused by circuit caused by aging is unstable, and its occurrence frequency may be compared with
It is high；Based on the reason, counter is set in above-mentioned power supply stability supervisory circuit, when same running parameter is in setting time scope
The interior number fluctuated reaches certain numerical value, then can be determined that the fluctuation occurs aging for power supply group internal component and caused
Circuit it is unstable caused by fluctuation, it is necessary to further be safeguarded and checked, to predict failure in advance.
