Then please refer to Fig. 2, about the circuit diagram of the present invention's overall situation reset circuit.Be noted that herein, though below be that example describes with electronic package shown in Fig. 2 and circuit layout, overall reset circuit 10 of the present invention does not only limit and can be made of electronic package shown in Fig. 2 and circuit layout thereof.
The switching controls module 11 of overall situation reset circuit 10 comprises the first switch module Q1, and the first switch module Q1 is a metal oxide semiconductcor field effect transistor (MOSFET) in the present embodiment, but the present invention is not as limit.The first switch module Q1 has source S, drain D and grid G.The source S of the power supply device 30 and the first switch module Q1 electrically connects, and the drain D of the first switch module Q1 electrically connects with motherboard 20 again, with the system power supply signal of output for motherboard 20 standbies.Grid G is in order to the whether conducting of control source S and drain D.
Reply control module 12 and comprise second switch module Q2 and a plurality of capacitor C 1, C2 and a plurality of resistance R 1, R2, wherein partition capacitance and resistance are in order to adjust the degree of stability of this circuit.Owing to be not emphasis of the present invention place, so do not repeat them here its effect.Second switch module Q2 is a bipolar junction transistor (BJT) in the present embodiment, but the present invention is not as limit.Second switch module Q2 has collector C, emitter E and base stage B.Wherein base stage B and control signal generating module 40 electrically connects, and can change its current potential height by control signal, with the whether conducting of determined set electrode C and emitter E.Collector C and motherboard 20 electrically connect, to receive via 20 system for transmitting power supply signals of motherboard.The grid G of emitter E and capacitor C 1 and the first switch module Q1 electrically connects, with the current potential height that discharges and recharges the control grid G by capacitor C 1.Thus, can determine whether the first switch module Q1 exports the system power supply signal for motherboard 20 standbies.
Then please refer to Fig. 3, about the method step process flow diagram of the present invention's overall situation replacement.Be noted that herein, though below be the method that the example explanation overall situation of the present invention is reset with electronic package shown in Fig. 2 and circuit layout, the present invention does not limit and need utilize electronic package shown in Fig. 2 and circuit layout to reach the method that the overall situation of the present invention is reset.
The method that the overall situation of the present invention is reset at first can carry out step 301: the input power supply signal to the switching controls module to produce the system power supply signal to replying control module.
At first power supply device 30 can be imported the source S of power supply signal to the first switch module Q1.And the grid G of the first switch module Q1 via resistance R 1 ground connection, therefore grid G is an electronegative potential under original state, and makes source S and drain D conducting.Therefore import power supply signals to source S when power supply device 30, drain D output system power supply signal to motherboard 20 with standby power as motherboard.This moment, the base stage B of second switch module Q2 was a noble potential, so second switch module Q2 and being failure to actuate.
Next carry out step 302: input control signal is to the second switch module of replying control module.
When user's desire is carried out computer system 1 flow process that the overall situation resets, by control signal generating module 40 before computer system 1 shutdown input control signal to the second switch module Q2 that replys control module 12.Wherein the user can come requirement control signal generating module 40 to send control signal by Keyboard Control software, operating system or firmware option, but the present invention is not exceeded with above-mentioned method.
This control signal is that may command second switch module Q2 carry out step 303: control second switch module utilizes the system power supply signal that electric capacity is charged.
When control signal generating module 40 transmit a control signal to reply control module 12 after, the base stage B controlled signal of second switch module Q2 pulls into electronegative potential, and makes and collector C and emitter E conducting simultaneously the system power supply signal is transferred to capacitor C 1.Thus, capacitor C 1 can be utilized the system power supply signal and begin charging.
Then carry out step 304: control switching controls module is cut off the transmission of system power supply signal.
After capacitor C 1 charging arrived noble potential, the grid G of the first switch module Q1 also arrived noble potential equally, and cuts off the conducting of source S and drain D.Thus, i.e. may command switching controls module 11 input of signal of cutting off the electricity supply makes that motherboard 20 can't the receiving system power supply signal, and loses power supply fully.
After being cut off the system power supply signal, the second switch module Q2 that replys control module 12 carry out step 305 immediately: control capacitance is discharged automatically.
After the source S of the first switch module Q1 and drain D were cut off conducting, the system power supply signal promptly can't be sent to motherboard 20, so second switch module Q2 also can't receive the system power supply signal.Under this situation, capacitor C 1 be because of can't receiving the input of system power supply signal again, so can slowly discharge and reduce to electronegative potential resistance R 1.
Carry out step 306 at last: control switching controls module recovery output system power supply signal.
When capacitor C 1 was reduced to electronegative potential, grid G was also reduced to electronegative potential simultaneously, and made source S and drain D conducting.Therefore the first switch module Q1 again the transmission system power supply signal to motherboard 20.
And this moment, the base stage B of second switch module Q2 was identical with step 301, can return back to noble potential.Therefore behind transmission system power supply signal again, not conducting of second switch module Q2 is not so capacitor C 1 can be charged once more.
Thus, motherboard 20 can receive the system power supply signal for its standby again, and computer system 1 can be finished the flow process that the overall situation is reset.
Be noted that herein the method that the overall situation of the present invention is reset is not exceeded with above-mentioned order of steps, as long as can reach purpose of the present invention, but the also change of above-mentioned order of steps.
By above-mentioned method and circuit, the user can carry out the overall situation to computer system 1 easily and reset, and can solve the disappearance of prior art.
To sum up institute is old, and no matter the present invention everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the present invention's interest field required for protection should be as the criterion so that the scope of claims is described naturally, but not only limits to the foregoing description.
