Including a single-chip microcomputer 201 in the control module 200, is one to be numbered the PIC16C84 single-chip microcomputer in the present embodiment.Its RA0 to RA3 pin is in order to read the set condition of thumb-acting switch 101, oscillator 202 is in order to provide single-chip microcomputer 201 required frequency of operation, reset switch 203 is as the replacement purposes of proving installation, when the system for computer power supply does not cut off, and need reset test period the time, after setting finishes, with the test process of reset switch 203 replacement proving installations.Another using time is for when the proving installation remarkable action, with reset switch 203 replacement test processs.Reset switch 203 is parallel with an electric capacity 204, as the protection purposes.
Include one first diode 301 and one second diode 302 in the trigger element 300, both connect with series system, and the cathode terminal of first diode 301 is connected to power pin in the PCI slot by a resistance 305, in order to the monitoring power supply state.The anode tap of second diode 302 is coupled with a first transistor 303, its emitter-base bandgap grading end ground connection, source terminal is connected to power end by a resistance 306, the source terminal of transistor seconds 304 is connected to power end by a resistance 307 equally, be coupled with a resistance 308 between the base terminal of the source terminal of the first transistor 303 and transistor seconds 304, the output terminal of trigger element 300 is coupled to one of them pin of the single-chip microcomputer 201 in the control module 200.
When power supply disappears, because motherboard capacitance discharges speed can be slow excessively, therefore utilize its current potential of two diode (not shown) filtering earlier, utilize first diode 301 and second diode 302 to do wave shaping again.
Single-chip microcomputer 201 in power supply switch unit 400 and the control module 200 couples, include one the 3rd transistor 401 and the 4th transistor 402, its base terminal (Base) is coupled with a resistance 403 and resistance 404 respectively, the source terminal (Source) of the 3rd transistor 404 and the 4th transistor 402 couples a power connection respectively, first power connection 405 is connected to power switch, another second source joint 406 same source terminals with the 3rd transistor 404 and the 4th transistor 405 couple, second source joint 406 is electrically connected to the power switch of motherboard, make when computer system power-on, proving installation is used the system power supply of power supply unit as working power, and when computing machine cuts out, proving installation then uses standby (suspend) power supply in the power supply unit as working power, and reach the purpose that loop cycle is tested, with the power surges of checking motherboard could bear continuous start and close.
The testing process of proving installation disclosed in the utility model below will be described.
Before beginning test,, and proving installation disclosed in the utility model is installed in the PIC slot, and sets test period the power-off of computer system.
Whole operation at first, proving installation will be monitored the power pin in the PCI slot.Trigger element 300 will send a trigger pip when power supply disappears, cause the single-chip microcomputer 201 in the control module 200 to be started working, after the time that sets when the test period of single-chip microcomputer 201 timing, to export a control signal, cause two pins of electric power starting on the motherboard (POWER ON) to do short circuit, the action of short circuit is exactly the open system power supply.
And the judgement of test result, according to the foundation of the test period that sets as the good and bad judgement of motherboard, when setting test period when being 15 seconds, motherboard can not have long off-mode, maximum duration can not be above 15 seconds, surpass 15 seconds, the part on the expression motherboard has problem and can't start shooting.
Start and close proving installation disclosed in the utility model can be in the motherboard impact of its electric current of Pretesting to its parts of dispatching from the factory.
When the electric power starting of computer system, the computer-internal parts can not accepted the power surges of start and close, yet under this kind situation, its power supply all passes through the prior processing of power supply unit, can't cause too big injury to the part on the motherboard.And the situation of instant cut-off, if not pushing power switch takes place as yet in power supply supply again immediately after outage sometimes, computing machine is start again just, and under this situation, power supply does not then directly enter motherboard by power supply unit by alternating current, in some cases, will cause some parts impaired.Therefore, proving installation disclosed in the utility model, the continuous measuring current of can going round and beginning again is to the impact of motherboard, and the quality of decision motherboard.Say that further the utility model utilizes setup unit as the input of test period, with the analog form input test cycle, more can accurately grasp the test duration compared with prior art, and can judge the quality of motherboard.
Though the utility model with aforesaid preferred embodiment openly as above; right its is not in order to limit the utility model; any those of ordinary skills; in not breaking away from spirit and scope of the present utility model; change when doing some equivalences, therefore scope of patent protection of the present utility model is as the criterion with claim.
