As shown in Figure 1, the early warning failure device 2 of the power supply unit of preferred embodiment of the present invention, be the inside that is disposed at a power supply unit 1, this power supply unit 1 then is to be installed on large scale system (as servomechanism, figure does not show) inside, setting by the early warning failure device 2 of the power supply unit of preferred embodiment of the present invention, make power supply unit 1 in the time will using up its serviceable life, can send alert news, and then make the large scale system supvr carry out due emergency measure ahead of time, for example do system backup or change standby power supply unit.The power switch of pressing large scale system as the large scale system supvr is with its unlatching (POWERON) time, will start power supply unit 1, the alternating current that makes input is via after the rectification of the power-switching circuit in the power supply unit 1 10, being filtered into direct current, output to radiator fan 11, large scale system inside more respectively, and the inside of the early warning failure device 2 of this power supply unit.Owing to the circuit of power-switching circuit 10 inside and as flowing mode is by prior art, and non-feature of the present invention, so be not described in detail.
Shown in figure 2,3, the early warning failure device of power supply unit of the present invention, its preferred embodiment 2 comprises a microprocessor 3, a storer 4 and an early warning circuit 5.
This microprocessor 3 electrically connects with the power-switching circuit 10 of this power supply unit 1, when power supply unit 1 start, the alternating current of input power supply unit 1 is in the rectification via power-switching circuit 10, after being filtered into direct current, except exporting radiator fan 11 to, large scale system inside, also output to simultaneously this microprocessor 3, this microprocessor 3 is activated, because each power supply unit 1 all has certain T in serviceable life, so can in microprocessor 3, set a time cycle t, make the each start of power supply unit 1 operate to a period of time and promptly count once (adding 1), to obtain a count value X (making X=X+1) after upgrading, and in microprocessor 3, set the number of times X1 of a preset count, wherein X1=T/t.
So, this microprocessor 3 is in order to whenever power supply unit running during to time cycle t that one sets, counting once (adds 1), to obtain a count value X (X=X+1) after upgrading, and the counts X1 of a count value X after will upgrading and a setting makes comparisons, count value X after upgrading is during less than the counts X1 that sets (X＜X1), this microprocessor 3 will continue counting, when counts X1 that this count value X equals to set (X=X1), this microprocessor 3 just stops counting and exports an early warning signal.
This storer 4, at this is with the preferable enforcement of FLASHRAM (flash memory) as storer 4, be provided with a transmission interface 6 between the two at this microprocessor 3 and this storer 4, make this microprocessor 3 the count value X after at every turn upgrading can be stored in these storer 4 inside, even after power supply unit 1 shutdown, this storer 4 still keeps stored content get off, make that this microprocessor 3 can read stored count value X in this storer 4 when power supply unit 1 each start.
This early warning circuit 5 comprises a cresset display 50 and a buzzer 51, and wherein this cresset display 50 is as preferable enforcement with LED (light-emittingdiode).This early warning circuit 5 is after receiving the early warning signal that this microprocessor 3 exported, drive cresset display 50 and this buzzer 51, make cresset display 50 luminous, and make this buzzer 51 send buzzer, to notify the large scale system supvr to carry out due emergency measure ahead of time, for example do system backup or change standby power supply unit.
In the present embodiment, be to use life-span T to be approximately 50000 hours, set time cycle t=200 hour, the number of times X1=T/t=250 of preset count still not as limit, be it should be noted that as an illustration, understand some difference the serviceable life of the power supply unit of different designs specification, serviceable life, T was directly proportional with the time cycle t of setting, if serviceable life, T was shorter, then the time cycle t of She Dinging is also shorter.
By above-mentioned technology, when power supply unit 1 each start, microprocessor 3 will read count value X stored in the storer 4 (when power supply unit 1 uses for the first time, count value X=0), when power supply unit 1 start running a period of time (for example time cycle t=200 hour), microprocessor 3 will be counted once (adding 1), with the count value X (for example being 1) after the acquisition renewal, be X=X+1, and the count value X after will upgrading (X=1) is stored in the storer 4, and this count value X (X=1) and the counts X1 (for example being 250) that sets are made comparisons, when X＜X1 (1＜250), microprocessor 3 will continue counting, and when X=X1, microprocessor 3 just stops counting, and export an early warning signal and give early warning circuit 5, sending alert news, and then make the large scale system supvr carry out due emergency measure ahead of time, for example do system backup or change standby power supply unit.
Because microprocessor 3 is in 1 each start running a period of time of power supply unit, for example after time cycle t=200 hour, just counting once, so if the time of this time running does not reach the time cycle t of setting, just less than is 200 hours, it for example is 190 hours, or be not integer multiple for the time cycle t that sets, it for example is 425 hours, 425=2 * 200+25, then the part (just aforesaid 190 hours and 25 hours) of not enough time cycle t will be cast out automatically, because microprocessor 3 can not counted the part of not enough time cycle t, thus error can be produced, under these circumstances, take place power supply unit 1 to reach Use Limitation possibly and count value X still (is X＜X1), so that has used inefficacy but to have little time the situation of early warning at power supply unit 1 less than the counts X1 that sets.Take place for fear of such situation, when setting the number of times X1 of counting, can set more certain digital more on the low sidely, or shortening gate time cycle t ability allowable error is to solve the above problems.
In sum, the early warning failure device of power supply unit of the present invention, really can be by above-mentioned structure, reach and make power supply unit have in the time will using up its serviceable life (when use is about to lose efficacy) to send alert news, and then make the large scale system supvr can carry out the effect of due emergency measure ahead of time.
